Seagrasses are unique plants; the only group of flowering plants to recolonise the sea. They occur on every continental margin, except Antarctica, and form ecosystems which have important roles in fisheries, fish nursery grounds, prawn fisheries, habitat diversity and sediment stabilisation. Over the last two decades there has been an explosion of research and information on all aspects of seagrass biology. However the compilation of all this work into one book has not been attempted previously. In this book experts in 26 areas of seagrass biology present their work in chapters which are state-of-the-art and designed to be useful to students and researchers alike. The book not only focuses on what has been discovered but what exciting areas are left to discover. The book is divided into sections on taxonomy, anatomy, reproduction, ecology, physiology, fisheries, management, conservation and landscape ecology. It is destined to become the chosen text on seagrasses for any marine biology course. © 2006/2007 Springer. All Rights Reserved.

A half-century of research has identified that mass media portrayals of women are influential in shaping their self-image and self-esteem, as well as men's and societies' views of women. Comparatively few studies have examined mass media portrayals of men and male identity, and gender studies have often assumed these to be unproblematic. But, in a post-industrial era of massive economic, technological and social change, research shows mass media are projecting and propagating new images of male identity from Atlas Syndrome workaholics and 'deadbeat dads' to 'metrosexuals' and men with "a feminine side" with potentially significant social implications.

The benchmark approach provides a general framework for financial market modeling, which extends beyond the standard risk-neutral pricing theory. It permits a unified treatment of portfolio optimisation, derivative pricing, integrated risk managemetn and insurance risk modeling. Th existence of an equivalent risk-neutral pricing measure is not required.Instead, it leads to pricing formulae with respect to the real-world probability measure. This yields important modeling freedom which turns out to be necessary for the derivation of realistic, parsimonious market models. The first part of the book describes the necessary tools fromprobability theory, statistics, stochastic calculus and the theory of stochastic differential equations with jumps. The second part of devoted to financial modeling by the benchmark approach. Various quajtitative methods for the real-world pricing and hedging of derivatives are explained. The general framework is used to provide an understanding of the nature of stochastic volatility. The book is intended for a wide audience that includes quantitative analysts, postgraduate students and practitioners in finance, economics and insurance. It aims to be a self- contained, accessible but methematically rigorous introduction to quantitative finance for readers that have a reasonable mathematical or quantitative background. Finally, the book hsould stimulate inetrest in the benchmark approach by describing some of its power and wide applicability.

In the age when the miniaturization trend that has driven the semiconductor industry is reaching its limits, organic modification of semiconductors is emerging as a field that could give much-needed impetus. We review the current state of understanding of the functionalization of C(100), Si(100), and Ge(100) surfaces through chemisorption of alkenes and alkynes, focusing on adsorbate structural control. While reactions on C(100) show most of the properties expected for concerted cycloaddition reactions such as [2+2] and [4+2] (Diels–Alder) processes, reactions on Si(100) present a wide range of variant behavior, including in some cases the prominence of non-cycloaddition products. More general stepwise free-radical addition processes are seen to provide a better description of reactions on Si(100), their prominence being attributed to either the non-existence or ineffectiveness of π bonding within surface silicon dimers. The investigations of these systems provide not only insight into driving mechanisms for chemisorption but also motivation for the development of new techniques of organic functionalization on semiconductors.

Interactions within ecological communities usually involve many species and pose intriguing challenges for ecologists who wish to map and disentangle them. To simplify this task we often assume that the interactions do not change in strength or direction and that the identities of the key species remain the same. Species can be 'pigeon-holed' into convenient categories such as 'pollinator', 'competitor', 'pest' or even 'redundant' using these assumptions. This makes programs of conservation or pest management easier to implement, but is also ignores an emerging body of evidence that interactions between species vary between situations, places and times. In this chapter we will explore the complexity of effects that arise from changes in tereactions between species. We also consider how such effects may be modelled and predicted,a nd illustrate how ecological insight can be used to guide management decisions.

The recent devlopment of cell biolofy technques for bacteria to allow visualisation of fundamental processes in time and space, and their use in synchronous populations of cells, has resulted in a dramatic increase in our understanding of cell division and it regulation in these tiny cells. The first stage of cell division is the formation of a Z ring, composed of apolymerised tubulin-like protein, FtZ,at the division site precisely at midcell. Several membrane-associated division proteins are then recruited to this ring to forma complex, the divisome, which causes invagination of the cell envelope layers to form a division septum. The z Ring marks the future division site, and the timing of assembly and positioning of this structure are important in determining where and when division will take place in the cell. Z ring assembly is controlled bnu many factors including negative regulatory mechanisms such as Min and nucleoid occlusion that influence Z ring positioning and FtZ accessory proteins that bind to FtZ directly and modulate its polymerisation behaviour. The replication status of the cell also influences the positionin of the Z ring,w hich may allow the tight coordination between DNA replication and cell division required toproduce two identical newborn cells.

Diabetes is known to induce a range of micro-and macrovascular compliacations with the latter resutling in premature and accelerated atherosclerosis. Thus people with diabetes have a 2-4 fold increased risk of developing cardiovascular diseases which is responsible for ca. 50% of deaths amongst people with diabetes. The mechanisms behind this elevated risk are still not fully understood, though there is now increasing evidence for a role of glycation and clycoxidation reactions induced by hyperglycemia. This article reviews current knowledge of the role that these reactions play in diabetes-induced atherosclerosis with particular emphasis on the molecular reactions that result in the modification of lipoproteins, and the consequences of these reactions on cellular metabolism.

© 2006 by World Scientific Publishing Co. Pte. Ltd. All rights reserved. A climatology of dust reporting days from 1995 to February 2004 has been prepared for the central eastern Australia region. The climatology reveals a total of 55 "dust days," consisting of 43 dust days associated with fronts. Of these 24 were classified as being embedded in the zonal westerlies in the Great Australian Bight (GAB) or in westerlies produced by from low-pressure systems in the GAB. The remaining 19 were associated with fronts over eastern Australia where high pressure systems in the GAB generated postfrontal south to southeast winds. Two case studies of dust storm generation and transport were modeled using an integrated wind erosion prediction system. The model predictions were broadly consistent with both satellite images highlighting dust and with the synoptic observations that reported dust.

Type IV pili or fimbriae are non-flagellar, filamentous surface appendages that are associated with a number of biological activities in bacteria. These processes include a form of surface translocation termed twitching motility; bacteriophage sensitivity; attachment to biotic (bacteria, plant, animal) and abiotic surfaces; biofilm development; and the uptake of naked DNA by natural transformation. Many of these biological functions are reliant on the ability of these structures to extend and retract.

Biotechnology requires robust and predictable expression of transgenes. Most commercial Genetically Modified (GM) crops contain the viral 35S promoter to drive insecticide and herbicide resistance genes. In cotton there have been reductions in efficacy of Bacillus thuringiensis toxin (Bt) expressing plants late in the season that have been attributed to reductions in promoter activity. We have used genomic approaches to identify cotton genes whose expression remains high during the season to find promoters that might better maintain expression of transgenes in the field. A cDNA library from young late season leaves was used to generate about 2000 ESTs. Clustering of ESTs was used to determine relative transcript abundance and identify the most highly-expressed genes. These were primarily photosynthetic and housekeeping genes and some metabolic genes. The ESTs were printed to a small cDNA microarray and probed with both early- and late-season leaf mRNAs. Absolute fluorescence levels were used to rank genes and confirm the EST abundance data. Candidate genes, including the small subunit of Rubisco (RbcS) were selected. An RbcS promoter (Genbank Accession DQ648074) was isolated and analysed in both Arabidopsis and cotton linked to a GUS reporter gene. Expression of the reporter gene was consistently high in green tissues throughout the life cycle of cotton in the glasshouse, and in the field. A number of other candidate promoters have been identified that may be useful in a variety of biotechnology applications. Copyright © 2006 The Japanese Society for Plant Cell and Molecular Biology.

The natural ecosystems of the Northeast Region of Brazil (NEB) have experienced persistent drought episodes and environmental degradation during the past two decades. In this study, we examined the spatial heterogeneity and temporal dynamics of the NEB using a 20-year time series of Normalized Difference Vegetation Index (NDVI) observations, derived from the National Oceanographic and Atmospheric Administration (NOAA)-Advanced Very High Resolution Radiometer (AVHRR) instrument. A set of 12 000 spatially distributed NDVI values was analysed to investigate significant deviations from the mean-monthly values of the base period (19822001) in the study area. Various statistical analyses involving minimum, mean and maximum values, coefficient of variation (CV), standardized anomalies (Z-scores), and 36-month running mean were applied to monthly NDVI values to identify spatial and temporal variations in vegetation dynamics. We found strong seasonal oscillations in the vegetation-growing season (FebruaryMay) over the NEB study area, with maximum NDVI observed in AprilMay and seasonal variations, expressed by the CV, ranging from 14% to 32%. In addition, a consistent upward trend in vegetation greenness occurred over the period 19841990, and was strongly reversed in the subsequent period 19911998. These upward and downward trends in vegetation greenness followed an inter-annual oscillation of not, vert, similar78 years. We also found that dry season peak (September) latitudinal variations in NDVI were 2025% greater in 19911999 than 19821990 across the study region. The results of this study suggest that patterns in NEB vegetation variability were a result of the impact of enhanced aridity occurring over the last decade of the 20th century.

Longitudinal data for Lock and Barrett's (2003) universal prevention trial is presented, along with data from 12-month follow-up to 24-and 36-month follow-up. Results of this study indicate that intervention reductions in anxiety reported in Lock and Barrett were maintained for students in Grade 6, with the intervention group reporting significantly lower ratings of anxiety at long-term follow-up. A significant Time × Intervention Group x Gender Effect on Anxiety was found, with girls in the intervention group reporting significantly lower anxiety at 12-month and 24-month follow-up but not at 36-month follow-up in comparison to the control condition. Results demonstrated a prevention effect with significantly fewer high-risk students at 36-month follow-up in the intervention condition than in the control condition. Results are discussed within the context of prevention research. Copyright © 2006 by Lawrence Erlbaum Associates, Inc.

Increased contamination of waterways has lead to many impacts on organisms, including effects on reproduction. A suite of endocrine-disruptive chemicals (DECs) has been shown to mimic sex hormones in vertebrates and their presence is an important bioindicator of environmental degradation. We examined expression of vitellogenin (Vtg, a female yolk protein) in male toadfish (Tetratenos glaber), as an indicator of EDC presence in estuaries around Sydney, Australia. First we demonstrated induction of Vtg in males from unpolluted estuarine sites through injection of 17beta-oestradiol. Second, serum of fish from polluted and unpolluted estuaries was collected and examined by reducing-polyacryamide gel electrophoresis (SDS-PAGE). While females from polluted (downstream from sewage treatment plants, and subject to urban runoff) and less polluted sites all expressed Vtg in blood serum, males from less polluted sites showed little or no evidence of Vtg expression. however, most males from heavilty polluted sites showed moderate to high levels of vtg expression indicating that EDCs were present and affecting normal endocrine function in males. We suggest that simple biochemical examinations of EDS effects, such as vtg induction in males, are useful rapid assessment methods wich can provide evidence upon which further, more detailed studies may be undertaken.

Mg-Ti-H thin films are found to have very attractive optical properties: they absorb 87% of the solar radiation in the hydrogenated state and only 32% in the metallic state. Furthermore, in the absorbing state Mg-Ti-H has a low emissivity; at 400 K only 10% of blackbody radiation is emitted. The transition between both optical states is fast, robust, and reversible. The sum of these properties highlights the applicability of such materials as switchable smart coatings in solar collectors. © 2006 American Institute of Physics.

We present an exact theory for modelling the modes of two-dimensional photonic crystals with a truly infinite cladding. It builds on our previous implementation of the fictitious source superposition method for simple point defects that is based on three key ideas: the use of fictitious sources to modify response fields so defects can be introduced; the representation of the defect mode as a superposition of solutions of quasiperiodic field problems; and the reduction of the twodimensional superposition to a highly efficient, one-dimensional average. Here we describe an elegant extension to model a compound, multiple scatterer, defect in a given layer, and then build on this to construct an arbitrary defect from multiple layers of compound defects. We demonstrate the method's accuracy and efficiency, and present two-and three-dimensional results. We also demonstrate the strengths of the method for difficult problems, such as where a mode is highly extended near cutoff.

The one-number census approach was developed by the Office for National Statistics to adjust the counts from the 2001 census of England and Wales for undernumeration. The method is underpinned by an assumption of independence between the count of the population that was given by the 2001 census and the count that was given by the Census Coverage Survey. Some dependence was, however, detected, and the paper describes the strategy that was used to measure dependence and to adjust the 2001 census population estimates. Bruti-Liberati, N & Platen, E 2006, 'Approximation of Jump Diffusions in Finance and Economics', Computational Economics, vol. 29, no. 3-4, pp. 283-312. In finance and economics the key dynamics are often specified via stochastic differential equations (SDEs) of jump-diffusion type. The class of jump-diffusion SDEs that admits explicit solutions
is rather limited. Consequently, discrete time approximations are required. In this paper we give a survey of strong and weak numerical schemes for SDEs with jumps. Strong schemes provide pathwise
approximations and therefore can be employed in scenario analysis, filtering or hedge simulation. Weak schemes are appropriate for problems such as derivative pricing or the evaluation of risk measures
and expected utilities. Here only an approximation of the probability distribution of the jump-diffusion process is needed. As a framework for applications of these methods in finance and economics we use
the benchmark approach. Strong approximation methods are illustrated by scenario simulations. Numerical results on the pricing of options on an index are presented using weak approximation methods.

Mycoplasma hyopneumoniae, the causative agent of porcine enzootic pneumonia, colonizes the respiratory cilia of affected swine causing significant economic losses to swine production worldwide. Heparin is known to inhibit adherence of M. hyopneumoniae to porcine respiratory epithelial cilia. M. hyopneumoniae cells bind heparin but the identity of the heparin-binding proteins is limited. Proteomic analysis of M. hyopneumoniae lysates identified 27 kDa (P27), 110 kDa (P110) and 52 kDa (P52) proteins representing different regions of a 159 kDa (P159) protein derived from mhp494. These cleavage fragments were surface located and present at all growth stages. Following purification of four recombinant proteins spanning P159 (F1P159, F2P159, F3P159 and F4P159), only F3P159 and F4P159 bound heparin in a dose-dependent manner (Kd values 142.37 ± 22.01 nM; 75.37 ± 7.34 nM respectively). Scanning electron microscopic studies showed M. hyopneumoniae bound intimately to porcine kidney epithelial-like cells (PK15 cells) but these processes were inhibited by excess heparin and F4P159. Similarly, latex beads coated with F2P159 and F4P159 adhered to and entered PK15 cells, but heparin, F2P159 and F4P159 was inhibitory. These findings indicate that P159 is a post-translationally cleaved, glycosaminoglycan-binding adhesin of M. hyopneumoniae.

Habitat and microhabitat preferences and site fidelity of Orectolobus ornatus were assessed between September 2002 and August 2003 to assess potential suitability of marine reserves for its conservation. Of six rocky reef habitats available in the study area (sponge gardens, artificial structures, barren boulders, sand, sea grass, macroalgae), O. ornatus exhibited a significant preference for sponge gardens, artificial structures, and barren boulders habitats. Habitat preferences of males and females, and individuals <1 m and >1 m, did not differ. Orectolobus ornatus selected daytime resting positions with a high topographic complexity and crevice volume and did not select on the basis of prey availability. Habitat and microhabitat preferences may be related to the need for predator avoidance. Regular monitoring of 40 individually identified O. ornatus revealed that none was a permanent resident of the study area. Seven individuals exhibited short-term temporary fidelity to the study area; they were resighted frequently for part of an intensive 100-day survey. Remaining individuals were temporary visitors; they were resighted at most once after initial identification or returning after extended absences. Monthly population surveys confirmed the turnover of O. ornatus in the study area. The lack of long-term site fidelity suggests that small marine reserves will be ineffective as a conservation strategy for O. ornatus.

RATIONALE: Despite irrefutable epidemiologic evidence, cigarette smoking remains the major preventable cause of lung disease morbidity worldwide. The appetite-suppressing effect of tobacco is a major behavioral determinant of smoking, but the underlying molecular and neuronal mechanisms are not understood. Neuropeptide Y (NPY) is an orexigenic neuropeptide, whose activity in the hypothalamic paraventricular nucleus governs appetite. OBJECTIVES: To compare the effects of smoke exposure and equivalent food restriction on body weight, organ mass, cytokines, and brain NPY in Balb/c mice. METHODS: A pair-feeding study design compared smoke exposure (4 wk; 1 cigarette, 3 x /d, 5 d/wk) to equivalent food restriction (pair-fed) and sham-exposed control mice. RESULTS: Smoke exposure rapidly induced mild anorexia. After 4 wk, smoke-exposed and pair-fed groups were lighter than control mice (22.0 +/- 0.2, 23.2 +/- 0.5, 24.9 +/- 0.4 g, respectively; p < 0.05). Brown and white fat masses were only reduced by smoke exposure, relative to control mice. NPY concentration in the paraventricular nucleus was significantly and paradoxically reduced by smoke exposure, despite lower plasma leptin concentrations; this was not observed in the pair-fed group experiencing 19% food restriction. Adipose mRNA expression of uncoupling proteins, inflammatory cytokines interleukin 6 and tumor necrosis factor alpha, and adipose triglyceride lipase was decreased by smoke exposure, and even lower in pair-fed mice. CONCLUSIONS: In contrast to food restriction, smoke exposure caused a reduction in hypothalamic NPY and fat mass, and regulated adipose cytokines. These findings may contribute to understanding weight loss in smoking-related lung disease and in the design of more effective smoking cessation strategies.

Cholecystokinin (CCK) is a gastrointestinal satiety signal released from the duodenum to terminate feeding, via CCK1 receptors. CCK2 receptors are considered to be involved in anxiety. CCK2 receptor knockout mice have increased body weight and food intake. Little is known regarding the effects of CCK2 receptor deficiency on adipose distribution and hypothalamic feeding regulators such as neuropeptide Y (NPY), a powerful stimulator of feeding. Adult (10?week) CCK2 receptor knockout and wild-type mice were anaesthetized and killed by decapitation. Brain sections, organs and fat tissue were dissected. Plasma leptin, insulin and brain NPY content were measured by radioimmunoassay. Female CCK2 receptor knockout mice weighed more than control mice (22.0?±?0.2 vs. 19.9?±?0.4?g, P?0.05), with this difference being less marked in male mice (26.4?±?0.4 vs. 25.6?±?0.6?g). Fat masses in all locations sampled were significantly smaller in CCK2 receptor knockout mice of both genders (P?0.05), resulting in lower plasma leptin and insulin levels. NPY concentrations were significantly increased in arcuate nucleus and anterior hypothalamus in both male and female CCK2 receptor knockout mice, and total hypothalamic NPY content was increased by 7 and 9% in males and females, respectively (P?0.05). CCK2 receptor deletion was associated with increased body weight and hypothalamic NPY content, but reduced fat masses and plasma leptin and insulin. Increased NPY might contribute to increased food intake in CCK2 receptor knockout mice.

Using field data, Airborne Visible Infrared Imaging Spectrometer (AVIRIS) imagery, and Moderate-Resolution Imaging SpectroRadiometer (MODIS) data, a multi-scale analysis of ecosystem optical properties was performed for Sky Oaks, a Southern California chaparral ecosystem in the SpecNet and FLUXNET networks. The study covered a four-year period (2000-2004), which included a severe drought in 2002 and a subsequent wildfire in July 2003, leading to extreme perturbation in ecosystem optical properties. Two vegetation greenness indices (Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI)) and a measure of the fraction of photosynthetically active radiation absorbed by vegetation (fPAR) were compared across sampling platforms, which ranged in pixel size from 1 meter (tram system in the field) to 1000 m (MODIS satellite sensor). For the EVI, there was excellent agreement between MODIS, AVIRIS and the ground measurements (tram system). AVIRIS and tram-based NDVI and fPAR values were in close agreement. However, MODIS NDVI and fPAR values were consistently higher than those determined from the field and the aircraft sensor, and these differences could not be entirely attributed to differences in sampling scale. Interestingly, MODIS fPAR derived from backup algorithms (NDVI driven) was closer to the AVIRIS and tram fPAR under the cloudy conditions.

We assessed determinants of cord serum polychlorinated biphenyl (PCB) levels among 720 infants born between 1993 and 1998 to mothers living near a PCB-contaminated Superfund site in Massachusetts, measuring the sum of 51 PCB congeners (SPCB) and ascertaining maternal address, diet, sociodemographics, and exposure risk factors. Addresses were geocoded to obtain distance to the Superfund site and neighborhood characteristics. We modeled log10(SPCB) as a function of potential individual and neighborhood risk factors, mapping model residuals to assess spatial correlates of PCB exposure. Similar analyses were performed for light (mono-tetra) and heavy (penta-deca) PCBs to assess potential differences in exposure pathways as a function of relative volatility. PCB-118 (relatively prevalent in site sediments and cord serum) was assessed separately. The geometric mean of SPCB levels was 0.40 (range, 0.06818.14) ng/g serum. Maternal age and birthplace were the strongest predictors of SPCB levels. Maternal consumption of organ meat and local dairy products was associated with higher and smoking and previous lactation with lower SPCB levels. Infants born later in the study had lower SPCB levels, likely due to temporal declines in exposure and site remediation in 19941995. No association was found between SPCB levels and residential distance from the Superfund site. Similar results were found with light and heavy PCBs and PCB-118. Previously reported demographic (age) and other (lactation, smoking, diet) correlates of PCB exposure, as well as local factors (consumption of local dairy products and Superfund site dredging) but not residential proximity to the site, were important determinants of cord serum PCB levels in the study community. Choi, H & Speer, MS 2006, 'Effects of atmospheric circulation and boundary layer structure on the dispersion of suspended particulates in the Seoul metropolitan area', Meteorology and Atmospheric Physics, vol. 92, no. 3-4, pp. 239-254. A three-dimensional non-hydrostatic numerical model and lagrangian particle model (random walk model) were used to investigate the effects of the atmospheric circulation and boundary layer structure on the dispersion of suspended particulates in the Seoul metropolitan area. Initially, emitted particulate matter rises from the surface of the city towards the top of the convective boundary layer (CBL), owing to daytime thermal heating of the surface and the combined effect of an onshore wind with a westerly synoptic-scale wind. A reinforcing sea-valley breeze directed from the coast toward the city of Seoul, which is enclosed in a basin and bordered by mountains to its east, disperses the suspended particulate matter toward the eastern mountains. Total suspended particulate concentration (TSP) at ground level in the city is very low and relatively high in the mountains. Radiative cooling of the surface produces a shallow nocturnal surface inversion layer (NSIL) and the suspended particulate matter still present near the top of the CBL from the previous day, sinks to the surface. An easterly downslope mountain wind is directed into the metropolitan area, transporting particulate matter towards the city, thereby recycling the pollutants. The particulates descending from the top of the NSIL and mountains, combine with particulates emitted near the surface over the city at night, and under the shallow NSIL spread out, resulting in a maximum ground level concentration of TSP in the metropolitan area at 2300 LST. As those particles move toward the Yellow Sea through the topographically shaped outlet west of Seoul city under the influence of the easterly land breeze, the maximum TSP concentration occurs at the coastal site. During the following morning, onshore winds resulting from a combined synoptic-scale westerly wind and westerly sea breeze, force particulates dispersed the previous night to move over the adjacent sea and back over the inland metropolitan area. The re... Choi, H & Speer, MS 2006, 'The influence of synoptic-mesoscale winds and sea surface temperature distribution on fog formation near the Korean western peninsula', Meteorological Applications, vol. 13, no. 04, pp. 347-347. When high pressure is located near the Korean peninsula, a diffluent wind regime generally occurs over the Yellow Sea. At night or early morning, diffluent westerly winds occur on the western side of the Korean peninsula near Inchon city and encounter a combined land breeze and katabatic easterly offshore wind, resulting in conditions ranging from calm to a moderate westerly wind near the coast. Nocturnal radiational cooling of the land surface and the moisture laden westerly winds can cause air near the coast to become saturated, resulting in coastal advection fog. During the day, on the other hand, the synoptic-scale westerly wind is reinforced by a westerly sea breeze and is further reinforced by a westerly valley wind directed upslope towards the mountain top. Even if the resulting intensified onshore wind could transport a large amount of moisture from the sea over the land, it would be very difficult for fog to form because the daytime heat flux from the ground would develop the convective boundary layer inland from Inchon city sufficiently to reduce significantly the moisture content of the air. Therefore, fog does not generally form in situ over the inland coastal basin. When an area of cold sea water (10 °C average) exists approximately 25-50 km offshore and the sea surface temperature increases towards the coast, air parcels over the cool sea surface are cooled sufficiently to saturation, resulting in the formation of advection sea fog. However, at the coast, nocturnal cooling of the ground further cools the advected moist air driven by the westerly wind and causes coastal advection fog to form. © 2006 Royal Meteorological Society.

For the first time, scanning electron microscopy has been used to investigate the binding of gold nanoparticles to fingermarks placed on nonporous surfaces. The results show that gold nanoparticles, under standard MMDII conditions, bind preferentially to latent fingermark ridges on nonporous surfaces. Variation in surfactant concentration influences background development but does not affect the binding of gold nanoparticles to the ridges, while pH variation influences the binding to ridges but leaves valley regions unaffected.

Gold and silver nanoparticles using oleylamine as a stabilizer have been formulated for developing latent fingermarks on nonporous surfaces. These nanopowders are compared with conventional powders such as black powder, black magnetic powder, aluminum powder, and white powder. Gold nanopowder produced sharp and clear development of latent fingermarks without background staining. Scanning electron microscope images revealed that particles were concentrated in the fingermark ridge areas, with only minor amounts located in the valley regions.

A combination of cyclic voltammetry (CV), UV-vis-NIR spectroscopy and spectroelectrochemistry, hyper-Rayleigh scattering (HRS) [including depolarization studies], Z-scan and degenerate four-wave mixing (DFWM) [including studies employing an optically transparent thin-layer electrochemical (OTTLE) cell to effect electrochemical switching of nonlinearity], pump-probe, and electroabsorption (EA) measurements have been used to comprehensively investigate the electronic, linear optical, and nonlinear optical (NLO) properties of nanoscopic pi-delocalizable electron-rich alkynylruthenium dendrimers, their precursor dendrons, and their linear analogues. CV, UV-vis-NIR spectroscopy, and UV-vis-NIR spectroelectrochemistry reveal that the reversible metal-centered oxidation processes in these complexes are accompanied by strong linear optical changes, switching on low-energy absorption bands, the frequency of which is tunable by ligand replacement. HRS studies at 1064 nm employing nanosecond pulses reveal large nonlinearities for these formally octupolar dendrimers; depolarization measurements are consistent with lack of coplanarity upon pi-framework extension through the metal.

Imaging, vol. 2006, pp. 21304:1-21304:1. A study demonstrating how ultrafast laser radiation stimulates osteoblasts is presented. The study employed a custom made optical system that allowed for simultaneous confocal cell imaging and targeted femtosecond pulse laser irradiation. When femtosecond laser light was focused onto a single cell, a rise in intracellular Ca 2+ levels was observed followed by contraction of the targeted cell. This contraction caused deformation of neighbouring cells leading to a heterogeneous strain field throughout the monolayer. Quantification of the strain fields in the monolayer using digital image correlation revealed local strains much higher than threshold values typically reported to stimulate extracellular bone matrix production in vitro. This use of point targeting with femtosecond pulse lasers could provide a new method for stimulating cell activity in orthopaedic tissue engineering. Curtis, TP, Head, IM, Lunn, M, Woodcock, S, Schloss, PD & Sloan, WT 2006, 'What is the extent of prokaryotic diversity?', PHILOSOPHICAL TRANSACTIONS OF THE ROYAL SOCIETY B-BIOLOGICAL SCIENCES, vol. 361, no. 1475, pp. 2023-2037. The extent of microbial diversity is an intrinsically fascinating subject of profound practical importance. The term `diversity may allude to the number of taxa or species richness as well as their relative abundance. There is uncertainty about both, primarily because sample sizes are too small. Non-parametric diversity estimators make gross underestimates if used with small sample sizes on unevenly distributed communities. One can make richness estimates over many scales using small samples by assuming a species/taxa-abundance distribution. However, no one knows what the underlying taxa-abundance distributions are for bacterial communities. Latterly, diversity has been estimated by fitting data from gene clone libraries and extrapolating from this to taxa-abundance curves to estimate richness. However, since sample sizes are small, we cannot be sure that such samples are representative of the community from which they were drawn. It is however possible to formulate, and calibrate, models that predict the diversity of local communities and of samples drawn from that local community. The calibration of such models suggests that migration rates are small and decrease as the community gets larger. The preliminary predictions of the model are qualitatively consistent with the patterns seen in clone libraries in `real life. The validation of this model is also confounded by small sample sizes. However, if such models were properly validated, they could form invaluable tools for the prediction of microbial diversity and a basis for the systematic exploration of microbial diversity on the planet.

Multi-tiered sampling approaches are common in environmental and occupational exposure assessment, where exposures for a given individual are often modeled based on simultaneous measurements taken at multiple indoor and outdoor sites. The monitoring data from such studies is hierarchical by design, imposing a complex covariance structure that must be accounted for in order to obtain unbiased estimates of exposure. Statistical methods such as structural equation modeling (SEM) represent a useful alternative to simple linear regression in these cases, providing simultaneous and unbiased predictions of each level of exposure based on a set of covariates specific to the exposure setting. We test the SEM approach using data from a large exposure assessment of diesel and combustion particles in the U. S. trucking industry. The exposure assessment includes data from 36 different trucking terminals across the United States sampled between 2001 and 2005, measuring PM2.5 and its elemental carbon (EC), organic carbon (OC) components, by personal monitoring, and sampling at two indoor work locations and an outdoor "background" location. Using the SEM method, we predict the following: (1) personal exposures as a function of work-related exposure and smoking status; (2) work-related exposure as a function of terminal characteristics, indoor ventilation, job location, and background exposure conditions; and ( 3) background exposure conditions as a function of weather, nearby source pollution, and other regional differences across terminal sites. The primary advantage of SEMs in this setting is the ability to simultaneously predict exposures at each of the sampling locations, while accounting for the complex covariance structure among the measurements and descriptive variables. The statistically significant results and high R-2 values observed from the trucking industry application supports the broader use of this approach in exposure assessment modeling.

We have demonstrated a combined imaging system, where the physiology of biological specimens can be imaged and profiled at 10-20 frames per second whilst undergoing femtosecond laser irradiation. Individual GH3 cells labeled with the calcium fluorophore Fluo-3 were stimulated using a counter-propagating focused femtosecond beam with respect to the imaging system. As a result of the stimulation, calcium waves can be generated in COS cells, and laser-induced calcium oscillations are initiated in the GH3 cells. Single-photon fluorescence images and intensity profiles of the targeted specimens are sampled in real-time using a modified PerkinElmer UltraView LCI microscope. Copyright © 2006 Daniel Day et al.

Molecular dynamics simulations of the thermal behaviour of gold clusters containing 7, 13 and 20 atoms have been performed. Total energies and forces at each step of the simulation are calculated from first principles using density functional theory. Ion trajectories are then calculated classically from these forces. In each case the global minimum energy structure and a low-lying isomer are used as the starting structures. In most cases, the clusters do not exhibit a sharp transition from a solid-like phase to a liquid-like phase, but rather pass through a region of transformation between structural isomers that extends over a considerable temperature range. Solid-like behaviour is observed in the atomic trajectories of ther simulation at temperatures up to, or above, the bulk melting point. The 20-atom tetrahedral structure is the one exception, showing a sharo transition between solid-like and liquid-like phases at about 1200 K. The starting sturcture used in the simulation is shown to have a considerable effect upon the subsequent thermal behaviour.

Summary
1. Periphytic diatoms are used as indicators of water quality because their ecological tolerances or preferences to environmental variables are thought to be predictable. However, much of the present autecological information for periphytic diatoms has been derived from studies conducted in the northern hemisphere. In this present study we used periphytic diatoms to determine the impacts of inorganic nutrient pollution in a tidal river system in the temperate latitudes of south-east Australia. In so doing, we assess the suitability of the use of the ‘northern hemisphere’ ecological tolerance/preference data for periphytic diatoms.
2. Artificial substrates were used to collect periphytic diatoms at 35 sites, which were positioned along the riverbanks and the middle of the river at various distances upstream and downstream of the sewage outfall. The sampling design took into account tidal excursions and the observed sewage plume dynamics. Periphytic diatoms were collected during the austral winter month of August and the austral spring months of September and October. We deployed the artificial substrates for 4 weeks to allow the periphytic diatoms to recruit and colonise, before identifying and enumerating the assemblages.
3. Data analysis included two approaches: multivariate visualisations of combinations of environmental and biological data to investigate shifts in species structure of the periphytic diatom assemblage and multimetric indices based on ecological tolerance/preference data.
4. We found that the spatial patterns inferred from multivariate and multimetric analyses were consistent. Temporal variation in the composition of the periphytic diatom assemblage was greater than the spatial variation along horizontal sections of the river (in any one deployment) due mainly to shifts between winter and spring species.
5. Outfall effects were most apparent in winter, possibly because subsequent deployments were swamped by growth of spring periphyt...

A general Monte Carlo ray-tracing method for light guides with particles randomly dispersed in a matrix is presentedd. Previous ray-tracing approaches have been designed for undoped cylindrical light guides, where a propagating ray is deviated bu total internal reflection only. These geometrical principles are extended and further developed into a method of ra-tracing suitable for particle-doped systems. Redefining ray direction after deviation by a particle, obtaining ray/wall intercept points and angles, and calculation of ray reflection angles from a cylindrical surface are described. Simulations of light from a source LED traced through TRIMM-doped (Transparent Refractive Index Matched Micro-Particle) polymethyl methacrylate (PMMA) light guides have been performed. Distributions of the light exiting the walls of two concentrations of TRIMM-doped lgith guides are given, as an exampled of an application of the described ray-tracing method.

Vertical migration behaviour by the chainforming dinoflagellate Gymnodinium catenatum Graham was investigated using vertically-stratified laboratory columns. Under surface nutrient-deplete conditions, with nutrients added only at depth, 100% of cells underwent vertical migration (VM), starting downwards migration 3 h before the end of the light period and beginning upwards migration 3 h before the start of the light period. Cells in nutrient-replete columns showed no VM, but they were more dispersed in the upper layer during the dark compared to the light period. When surface layers (S) were nitrate-deplete (-N) and enriched with humic substances (H) contained in Huon River water and bottom waters (B) were nutrient replete (R) (SH-NBR), the pattern of VM was altered-50% of cells underwent migration and 50% remained at the pycnocline. In columns with nitrate-replete and humic-enriched surface layers (SHRBR), Most cells underwent VM, while 30% remained at the surface. Cells in SH-NBR columns showed increased N quotas and intra-cellular nitrate concentrations after 4 days, indicating nitrate uptake by G. catenatum in bottom layers. The concomitant increase in particulate organic nitrogen (PON) with the decrease in external nitrate concentrations in bottom layers provide convincing evidence that VM by G. catenatum facilitates nutrient retrieval at depth. However, addition of humic substances (a potential source of organic nitrogen) to surface layers did not ameliorate G. catenatum N depletion sufficiently to preclude the need for NO3- uptake at depth. Furthermore, there was no detectable pattern of increasing carbon (C) quota during the day (photosynthate accumulation) or increasing N quota during the night (nitrate assimilation).

Duggin, IG 2006, 'DNA replication fork arrest by the Bacillus subtilis RTP-DNA complex involves a mechanism that is independent of the affinity of RTP-DNA binding', JOURNAL OF MOLECULAR BIOLOGY, vol. 361, no. 1, pp. 1-6. In order to elucidate the mechanism of DNA replication fork arrest by the replication terminator protein (RTP)DNA complex, a set of RTP fusion proteins were constructed in which peptides of various sizes were fused to the C terminus; this placed the peptides at a surface location that was predicted to come into contact with the DNA replication machinery during fork arrest. The fusion proteins were capable of replication fork arrest in vivo, but they had a significantly reduced efficiency compared to wild-type RTP, which was not directly proportional to peptide size or sequence. Importantly, the fusion proteins retained completely normal RTPDNA binding affinity. These findings rule out the molecular clamp model as the sole explanation for fork arrest by RTP, and suggest that RTP interacts with the replication machinery in a manner that directly contributes to the fork arrest mechanism.

In the three domains of life, the archaea, bacteria, and eukarya, there are two general lineages of DNA replication proteins: the bacterial and the eukaryal/archaeal lineages. The hyperthermophilic archaeon Sulfolobus solfataricus provides an attractive model for biochemical study of DNA replication. Its relative simplicity in both genomic and biochemical contexts, together with high protein thermostability, has already provided insight into the function of the more complex yet homologous molecules of the eukaryotic domain. Here, we provide an overview of recent insights into the functioning of the chromosome replication machinery of S. solfataricus, focusing on some of the relatively well characterized core components that act at the DNA replication fork.

Swine erysipelas vaccines are routinely used to protect pigs against peracute and acute/urticarial forms of Erysipelothrix. Between 1995 and 1998, 34 swine herds across four Australian states experienced vaccine failure. Forty-four isolates of Erysipelothrix rhusiopathiae of serovars 2, 1a, 1b and 1b × 21 were recovered from 15 of these 34 vaccine breakdown herds. These isolates were characterised by restriction fragment length polymorphism (RFLP) analyses using RsaI and AluI on whole cell DNA and for the presence of plasmid DNA. Results were compared with those of 20 isolates from 16 herds unaffected by vaccine breakdown and 13 isolates representing 10 reference strains. The majority of breakdown herds possessed isolates of serovar 2 (9/15 herds), followed by serovar 1a (5 herds). No geographic predominance of a single serovar was evident. The identification of 10 RsaI profiles from whole cell DNA among the 44 isolates from 15 breakdown herds indicated that a single, new clonal lineage of E. rhusiopathiae was not responsible for vaccine failure. RsaI RFLP analyses detected a further 14 distinct profiles among 20 field strains unassociated with vaccine breakdowns, and none matched profiles of the 10 serovar reference strains for serovars 1a, 1b, 2 or 21. This technique is recommended for epidemiological studies of E. rhusiopathiae strains.

counter automata. We show that a group has word problem accepted by a blind
n-counter automaton in the sense of Greibach if and only if it is virtually
free abelian of rank n; this result, which answers a question of Gilman, is in
a very precise sense an abelian analogue of the Muller-Schupp theorem. More
generally, if G is a virtually abelian group then every group with word problem
recognised by a G-automaton is virtually abelian with growth class bounded
above by the growth class of G. We consider also other types of counter
automata. Elder, MJ 2006, 'A non-Hopfian almost convex group', Journal of Algebra, vol. 271, no. 1, pp. 11-21. In this article we prove that an 'isometric multiple HNN-extension' of a

Social Anxiety Disorder (SAD) is a heterogeneous and distressing problem for many children and youth. This review focuses on the etiology and maintenance of SAD, and examines research findings in several key areas of investigation: genetic or hereditary factors (twin and family studies), temperament characteristics (behavioural inhibition), and parent-child interactions (attachment, parenting styles). It is concluded that genetic influences, behavioural inhibition, and parent-child interactions play significant and interactive roles in the development and maintenance of SAD. Other influences such as peer relationships, social skills deficits, and traumatic experiences are also acknowledged. Ultimately, an understanding of such pathways should facilitate effective early screening and intervention of children at risk for severe social anxiety. © 2006 Taylor & Francis.

Recent literature and our previous observations indicated the presence of both NMDA and serotonin type 3 receptors in human platelets with very similar ionic currents to that of cultured mammalian neuronal receptors. Baseline electrophysiological data shows similar profile for platelets from both normal and schizophrenic subjects, whereas serotonin receptor studies exhibited the presence of 5-hydroxytryptamine type-3 (5-HT3) currents in both normal and schizophrenic platelets significantly different from each other. The two major differences observed were: first, 5-HT3 receptors present in the platelets of schizophrenic patients were four times more sensitive to serotonin than those present in the platelets of normal subjects and, second, that D: -serine in micro molar concentrations dampens this effect in platelets from schizophrenic patients but increases the sensitivity of serotonin for platelet 5-HT3 receptors of normal subjects. Patch clamp technique was used to measure the whole cell currents passing through serotonin receptors in these two types of human platelets. The currents were found to be 5-HT3 receptor currents as they were abolished by 10 microM D-tubocurarine. Similarly, micromolar concentrations of D: -serine increased the sensitivity of 5HT3 receptor currents in the normal human platelets but decreased it in the platelets of the schizophrenic patients. This effect was reversed when D-amino acid oxidase (0.3 microM) was co applied with 100 microM of D-serine, raising the possibility that D-serine by itself may act as a modulator for platelet 5-HT3 receptor channel currents. These observations raised exciting new questions about the role of platelet serotonin receptors and their regulation by D-serine.

The Brazilian Cerrado is an extensive and complex biome, characterized by rapid and abrupt land cover changes. Due to its dimensions and physiognomic variations, the Cerrado plays an important role regarding the water, energy, and carbon fluxes at both the regional and global scales. Therefore, the correct understanding of the structure and ecological functioning of this biome, particularly in the temporal domain, is of great importance. With this respect, in this study we compared the seasonal response and land cover discrimination of the major MODIS (MODerate resolution Imaging Spectroradiometer) biophysical indices: the normalized difference vegetation index (NDVI), the enhanced vegetation index (EVI), the leaf area index (LAI), and the fraction of absorbed photosynthetically active radiation (fAPAR). In spite of the fact the four indices showed similar temporal trends, the LAI showed the highest sensitivity to the seasonal variations of the natural and converted landscapes. On the other hand, the NDVI showed the best performance regarding land cover discrimination. Our results suggest a synergistic approach concerning the MODIS biophysical / ecological variables for land cover assessments and environmental monitoring of the Cerrado biome.

There is a degree of uncertainty in the public mind concerning the exact subject matter of nanotechnology. Novels such as Michael Crichtons Prey and the movie Agent Codie Banks have primed many to believe that nanotechnology is about tiny (and rather dangerous) nano-robots. Of course, most technically savvy individuals know better, but because this misconception exists there is an obligation on researchers in this field to communicate a more accurate understanding of the topic to the wider community. The Institute for Nanoscale Technology at the University of Technology, Sydney (UTS) has sought to bridge this gap in understanding.

Both molecules are covalently boudn with interaction energies of 1.85 and 1.43 eV for methanethiolate and benzenethiolate, respectively. The preferred binding site is slightly offset from the bridge sire i both cases towards the fcc-hollow. The potential energy durfacces (PES) have depths of 0.36 and 0.22 eV, the hollow sites are local maxima in both cases, and there is not barrier to diffusion ofthe molecule at the bridge site. The corresponding dimers are weakly bound for methanethiolate and benzenthiolate, with binding energies of 0.38 and 0.16eV, respectively, and the preferred binding geometry is with the two sulphur atoms close to adjacent atop sites. The barrier to dissociation of the dimer dimethyl disulphide is estimated to like between 0.3 and 0.35eV.

Bufflelgrass (Pennisetum ciliare syn. Cenchrus ciliaris) is an African grass that has been widely introduced in subtropical arid regions of the world to improve rangelands for cattle production. However, it can have a negative effect on the diversity of native plant communities. Buffelgrass was introduced to Sonora, Mexico in the 1970s as a means to bolster the cattle industry. Desmonte, the process by which native desert vegetation is removed in preparation for buffelgrass seeding, alters the land surface such that buffelgrass plots are easily detectable from aerial and Landsat satellite images. We estimated the extent of conversion to buffelgrass in a 1,850,000 ha area centered on Hermosillo, from MSS and TM images from 1973, 1983, 1990 and 2000. We then compared the relative above-ground productivity of buffelgrass to native vegetation using Normalized Difference Vegetation Index values (NDVI) from Landsat and Moderate Resolution Imaging Spectrometer (MODIS) satellite sensor systems. Buffelgrass pastures have increased from just 7700 ha in 1973 to over 140,000 ha in 2000. Buffelgrass pastures now cover 8% of the land surface in the study area. Buffelgrass pastures have lower net primary productivity, estimated by MODIS NDVI values, than unconverted desert land. The desmonte process removes trees and shrubs, while the buffelgrass plantings are often sparse, leading to an apparent net loss in net primary production from land conversion. We recommend that the desmonte process be discontinued until its efficacy and safety for native ecosystems can be established, and that a comprehensive plan for preserving biodiversity while accomodating economic development be established for this region of the Sonoran Desert in Mexico.

Since the birth of the lithium ion battery in the early 1990s, its development has been very rapid and it has been widely applied as power source for a lot of light and high value electronics due to its significant advantages over traditional rechargeable battery systems. Recent research demonstrates the importance of surface structural features of electrode materials for their electrochemical performance, and in this paper the latest progress on this aspect is reviewed. Electrode materials are either anodic or cathodic ones. The former mainly include graphitic carbons, whose surfaces can be modified by mild oxidation, deposition of metals and metal oxides, coating with polymers and other kinds of carbons. P, Through these modifications, the surface structures of the graphitic carbon anodes are improved, and these improvements include: (1) smoothing the active edge surfaces by removing some reactive sites and/or defects on the graphite surface, (2) forming a dense oxide layer on the graphite surface, and (3) covering active edge structures on the graphite surface. Meanwhile, other accompanying changes occur: (1) production of nanochannels/micropores, (2) an increase in the electronic conductivity, (3) an inhibition of structural changes during cycling, (4) a reduction of the thickness of the SEI (solid-electrolyte-interface) layer, and (5) an increase in the number of host sites for lithium storage.

Here we reported an effective method to prepare TiO2/C core-shell nanocomposites as active anode materials for lithium ion batteries with markedly ameliorated electrochemical performance. At first, a precursor, polyacrylonitrile coated nano-TiO2 particles, was formed by emulsion polymerization. Then the precursor was heat-treated under argon atmosphere to achieve the nanocomposites. The conductive carbon shell enveloped TiO2 nanoparticles and suppressed the aggregation of nanoparticles during cycling. Meanwhile, it combined closely with the nanocores, significantly enhanced kinetics of lithium intercalation and de-intercalation and diffusion coefficient of lithium ion. This provides a good way to improve the cycling and kinetics of nanoanode materials.

A new and effective method to prepare TiO2/C core-shell nanocomposites as active anode materials for lithium ion batteries with markedly ameliorated electrochemical performance is described. Initially a precursor, polyacrylonitrile coated nano-TiO2 particles, is formed by emulsion polymerization. This precursor is heat-treated under argon atmosphere to achieve the nanocomposite. The conductive carbon shell enveloped TiO2 nanoparticles and suppressed the aggregation of the core nanoparticles during cycling. In addition it is attached closely to the nano-cores, and the kinetics of lithium intercalation and de-intercalation, the apparent diffusion coefficient of lithium ions and the consequent cycling behavior are significantly enhanced. This provides a good way to improve cycling and kinetics of nano-anode materials Fu, WJJ, Hu, JB, Spencer, T, Carroll, R & Wu, GY 2006, 'Statistical models in assessing fold change of gene expression in real-time RT-PCR experiments', COMPUTATIONAL BIOLOGY AND CHEMISTRY, vol. 30, no. 1, pp. 21-26.

We demonstrate for the first time a nonlinear finite-difference time-domain (FDTD) analysis of optical parametric four-wave mixing (FWM) in an actual InGaAsP-InP-based racetrack microresonator, and the results are compared with measurements on an experimental prototype. It has been found from the two-dimensional (2-D) and three-dimensional FDTD analyses that the resonance frequencies can be reasonably predicted by an FDTD model by considering the strong material dispersion of the waveguide medium and that the wavelength conversion by FWM is not sensitive to the dimensionality of the model; thus, it is efficiently predicted by the 2-D FDTD model. Ganguli, B & Wand, MP 2006, 'Additive models for geo-referenced failure time data', Statistics in Medicine, vol. 25, no. 14, pp. 2469-2482. Asthma researchers have found some evidence that geographical variations in susceptibility to asthma could reflect the effect of community level factors such as exposure to violence. Our methodology was motivated by a study of age at onset of asthma among children of inner-city neighbourhoods in East Boston. Cox's proportional hazards model was not appropriate since there was not enough information about the nature of geographical variations so as to impose a parametric relationship. In addition, some of the known risk factors were believed to have non-linear log-hazard ratios. We extend the geoadditive models of Kamman and Wand to the case where the outcome measure is a possibly censored time to event. We reduce the problem to one of fitting a Poisson mixed model by using Poisson approximations in conjunction with a mixed model formulation of generalized additive modelling. Our method allows for low-rank additive modelling, provides likelihood-based estimation of all parameters including the amount of smoothing and can be implemented using standard software. We illustrate our method on the East Boston data.

The increasingavailability of atomic-level protein derived from X-ray crystallography and NMR spectroscopy, together with advances in computational power, have ushered in a new era of powerful theoretical apporaches to study protein mechanism,s and, by extension, use a computer-aided structural approach to drug design. Calssical molecular dynamics calculations, in which Newton's equations of motion are solved for all atoms in the system, has emerged as an important tool for analysing protein dynamics at physiologically relevant timescales, in ways that are either very difficult or impossible to do experimentally. Indeed, the computer is becoming a kind of virtual microscope that can observe things not observable by any other means. The availability of more sophisticated parallel computer clusters and program suites will lead to simulations thatw ill be capable of examining entire processes such as polypeptide folding pathways and reaction mechanisms. In this review, the incipient applicationof molecular dynamics analysis of ABC (ATP-Binding Cassette) trasporters is surveyed and discussed, with particular relevance to unresolved and controversial issues.

Loss of biodiversity and habitats is one of the greatest threats to the environment and education has a critical role to play in addressing this issue. This paper describes a teaching activity for first-year university students studying sustainable resource management at the University of Newcastle which established a partnership between education, government and the community to rehabilitate a nature reserve where biodiversity values were threatened by weed invasion. Students research the problem (weed invasion), quantitatively assess the impacts of weed invasion and management interventions, and work alongside a community-based bushcare group and government agency during on-ground rehabilitation of the reserve. Key outcomes for students have been knowledge and skills relevant to a critical issue for the Australian environment; a more optimistic attitude towards environmental issues and their potential to develop solutions; a positive perspective about the role of community involvement; continued participation in community bushcare groups outside the classroom; and personal involvement in solving a critical environmental issue. © 2003, Cambridge University Press.

Background N-3 and n-6 polyunsaturated fatty acids (PUFAs) have been hypothesized to have opposing influences on neonatal immune responses that might influence the risk of allergy or asthma. However, both n-3 eicosapentaenoic acid (EPA) and n-6 arachidonic acid (AA) are required for normal fetal development. Objective We evaluated whether cord blood fatty acid levels were related to neonatal immune responses and whether n-3 and n-6 PUFA responses differed. Methods We examined the relation of cord blood plasma n-3 and n-6 PUFAs (n = 192) to antigen- and mitogen-stimulated cord blood lymphocyte proliferation (n = 191) and cytokine (IL-13 and IFN-?; n = 167) secretion in a US birth cohort. Results Higher levels of n-6 linoleic acid were correlated with higher IL-13 levels in response to Bla g 2 (cockroach, P = .009) and Der f 1 (dust mite, P = .02). Higher n-3 EPA and n-6 AA levels were each correlated with reduced lymphocyte proliferation and IFN-? levels in response to Bla g 2 and Der f 1 stimulation. Controlling for potential confounders, EPA and AA had similar independent effects on reduced allergen-stimulated IFN-? levels. If neonates had either EPA or AA levels in the highest quartile, their Der f 1 IFN-? levels were 90% lower (P = .0001) than those with both EPA and AA levels in the lowest 3 quartiles. Reduced AA/EPA ratio was associated with reduced allergen-stimulated IFN-? level. Conclusion Increased levels of fetal n-3 EPA and n-6 AA might have similar effects on attenuation of cord blood lymphocyte proliferation and IFN-? secretion. Clinical implications The implications of these findings for allergy or asthma development are not yet known.

The authors describe 'collaborative problem solving,' a cognitive-behavioral approach for working with aggressive children and adolescents. The model conceptualizes aggressive behavior as the byproduct of lagging cognitive skills in the domains of flexibility, frustration tolerance, and problem solving. The goal is to train staff to assess specific cognitive skills that may be contributing to challenging behavior and to teach children new skills through collaborative problem solving. The authors present results from an inpatient unit that dramatically reduced rates of seclusion and restraint.

The ways in which invasive organisms influence native ecosystems remain poorly understood. For example, feral cane toads Bufo marinus have spread extensively through tropical Australia over the last 70 years, but assessments of their ecological impact remain largely anecdotal. We conducted experimental trials to examine the effect of cane toad presence on invertebrate fauna in relatively small (2.4 x 1.2 m) outdoor enclosures on a floodplain near Darwin in the wet-dry tropics. Toads significantly reduced invertebrate abundance and species richness, but only to about the same degree as did an equivalent biomass of native anurans. Thus, if toads simply replaced native anurans, the offtake of invertebrates might not be substantially different from that due to native anurans before toad invasion. However, our field surveys suggest that toads cause a massive (fourfold) increase in total amphibian biomass. The end result is that cane toads act as a massive nutrient sink in the floodplain ecosystem because they consume vast numbers of invertebrates but (unlike native frogs) are largely invulnerable to predation by frog-eating predators.

We investigated the relationships among attachment representation, social withdrawal, and depressive symptomatology in childhood. A total of 326 children aged 8 to 10 years participated in the study. Children completed a family drawing procedure to assess attachment representation, the Children's Depression Inventory and the Social Withdrawal subscale of the Personality Inventory for Youth. Social withdrawal and attachment representations indicative of attachment dysfunction were each found to be positively correlated with depressive symptomatology. Further, attachment representation was found to significantly moderate the relationship between withdrawal and depression such that the positive relationship between withdrawal and depression was attenuated in the absence of attachment representations indicative of attachment dysfunction. © 2006 Springer Science+Business Media, Inc.

Increased ocean temperatures are thought to be triggering mass coral bleaching events around the world. The intracellular symbiotic zooxanthellae (genus Symbiodinium) are expelled from the coral host, which is believed to be a response to photosynthetic damage within these symbionts. Several sites of impact have been proposed, and here we probe the functional heterogeneity of Photosystem II (PSII) in three coral species exposed to bleaching conditions. As length of exposure to bleaching conditions (32 degrees C and 350 mu mol photons m(-2) s(-1)) increased, the Q(A)(-) reoxidation kinetics showed a rise in the proportion of inactive PSII centers (PSIIX), where Q(B) was unable to accept electrons. PSIIX contributed up to 20% of the total PSII centers in Pocillopora damicornis, 35% in Acropora nobilis and 14% in Cyphastrea serailia. Changes in F-V/F-M and amplitude of the J step along fast induction curves were found to be highly dependent upon the proportion of PSIIx centers within the total pool of PSII reaction centers. Determination of PSII antenna size revealed that under control conditions in the three coral species up to 60% of PSII centers were lacking peripheral light-harvesting complexes (PSII beta). In P. damicornis, the proportion of PSII beta increased under bleaching conditions and this could be a photoprotective mechanism in response to excess light. The rapid increases in PSIIX and PSII beta observed in these corals under bleaching conditions indicates these physiological processes are involved in the initial photochemical damage to zooxanthellae.

The lordosis of the lumbar spine and body weight result in significant shear forces through the lumbosacral elise spaces. These forces result in translational motion across the disc space, which is resisted but not completely abolished by pedicle screw stabilization. It is postulated that this motion may be a factor in the development of nonunion of lumbar interbody fusions. An in vitro study of the micromotion of porcine specimens with serrated or smooth interbody spacers and subjected to shear forces under compressive preload was conducted to determinewhether the surface serrations on vertebral interbody implants significantly resist shear forces and resulting sagittal translation.

The beam splitter has a periodic structure and is planned for fabrication by serial bideposition in mutually orthogonal planes. Recent experimental data for form-birefringent silicon is used to establish the feasibility of the design for a beam splitter to be used at 1310 nm and at an angle of 45° in air.

Sediment toxicity tests in the laboratory are an important part of ecological risk assessments, yet how they relate to sediment toxicity in situ has rarely been explored. Using meta-analysis, we examined differences in the toxicity of sediment tested in Houseman, EA, Coull, BA & Ryan, LM 2006, 'A functional-based distribution diagnostic for a linear model with correlated outcomes', BIOMETRIKA, vol. 93, no. 4, pp. 911-926. In this paper we present an easy-to-implement graphical distribution diagnostic for linear models with correlated errors. Houseman et al. (2004) constructed quantile-quantile plots for the marginal residuals of such models, suitably transformed. We extend the pointwise asymptotic theory to address the global stochastic behaviour of the corresponding empirical cumulative distribution function, and describe a simulation technique that serves as a computationally efficient parametric bootstrap for generating representatives of its stochastic limit. Thus, continuous functionals of the empirical cumulative distribution function may be used to form global tests of normality. Through the use of projection matrices, we generalised our methods to include tests that are directed at assessing the normality of particular components of the error. Thus, tests proposed by Lange & Ryan (1989) follow as a special case. Our method works well both for models having independent units of sampling and for those in which all observations are correlated.

Remotely sensed, angle-based vegetation indices that measure vegetation amounts by the angle between an approximated soil line and a simulated vegetation isoline in the red-near-infrared reflectance space were developed and evaluated in this paper. Unsalan and Boyer previously proposed an angle-based vegetation index, thetas (denoted as thetas NDVI in this paper), based on the normalized difference vegetation index (NDVI) with the objective of overcoming the saturation problem in the NDVI. However, thetasNDVI did not consider strong soil background influences present in the NDVI. To reduce soil background noise, an angle-based vegetation index, thetasSAVI , based on the soil-adjusted vegetation index (SAVI), was derived using trigonometric analysis. The performance of thetasNDVI and thetasSAVI was evaluated and compared with their corresponding vegetation indices, NDVI and SAVI. The soil background influence on thetasNDVI was found to be as significant as that on the NDVI. thetasNDVI was found to be more sensitive to vegetation amount than the NDVI at low vegetation density levels, but less sensitive to vegetation fraction at high vegetation density levels. Thus, the saturation effect at high vegetation density levels encountered in the NDVI was not mitigated by thetasNDVI. By contrast, thetasSAVI exhibited insignificant soil background effects and weaker saturation, as in SAVI, but also improved upon the dynamic range of SAVI. Analyses and evaluation suggest that thetasSAVI is an optimal vegetation index to assess and monitor vegetation cover across the entire range of vegetation fraction density levels and over a wide variety of soil backgrounds Jiang, ZY, Huete, AR, Chen, J, Chen, YH, Li, J, Yan, GJ & Zhang, XY 2006, 'Analysis of NDVI and scaled difference vegetation index retrievals of vegetation fraction', REMOTE SENSING OF ENVIRONMENT, vol. 101, no. 3, pp. 366-378. The normalized difference vegetation index (NDVI) is the most widely used vegetation index for retrieval of vegetation canopy biophysical properties. Several studies have investigated the spatial scale dependencies of NDVI and the relationship between NDVI and fractional vegetation cover, but without any consensus on the two issues. The objectives of this paper are to analyze the spatial scale dependencies of NDVI and to analyze the relationship between NDVI and fractional vegetation cover at different resolutions based on linear spectral mixing models. Our results show strong spatial scale dependencies of NDVI over heterogeneous surfaces, indicating that NDVI values at different resolutions may not be comparable. The nonlinearity of NDVI over partially vegetated surfaces becomes prominent with darker soil backgrounds and with presence of shadow. Thus, the NDVI may not be suitable to infer vegetation fraction because of its nonlinearity and scale effects. We found that the scaled difference vegetation index (SDVI), a scale-invariant index based on linear spectral mixing of red and near-infrared reflectances, is a more suitable and robust approach for retrieval of vegetation fraction with remote sensing data, particularly over heterogeneous surfaces. The proposed method was validated with experimental field data, but further validation at the satellite level would be needed.

The electrochemical hydrogen storage properties of MgxSc1-x alloys are investigated both in thin film and bulk form. A comparison is made between the electrochemical, thermodynamic and structural properties of both systems. It is shown that the electrochemical properties of the thin films and bulk materials strongly resemble one another. For compositions where x > 0.8, a sudden decrease in capacity is observed in both cases, which is argued to be due to a structural transformation of the resulting hydride from fluorite to rutile. The formation of a fluorite structure for the bulk hydride was confirmed by X-ray diffraction. Both galvanostatic and equilibrium voltage curves show a plateau in the electrode potential, indicative of a phase transition. Partial discharge of a MgSc bulk hydride showed retention of the face-centered cubic host structure. Overall, the thin film materials are able to give a good indication of the electrochemical processes that take place in a simplified two-dimensional model system. This knowledge can subsequently be used for understanding the bulk system, as both bulk and thin film materials complement each other very well. © 2005 Elsevier B.V. All rights reserved.

Caudal autotomy is widely employed by lizards to facilitate escape from predators. Despite conferring immediate short-term benefits, tail loss may involve substantial costs, including impaired locomotor performance, loss of energy reserves, and reduced survival during subsequent encounters with predators. We investigated whether tail autotomy influenced the running speeds and anti-predator behaviors of adult male Velvet Geckos, Oedura lesueurii. This nocturnal terrestrial gecko displays a range of anti-predator behaviors (tail waving and vibration, slow movement, and crypsis) in the presence of scent from the predatory Broad-headed Snake, Hoplocephalus bungaroides. Since tailless geckos cannot use tail displays to attract predatory strikes away from the torso, we hypothesized that tailless geckos would spend more time motionless in the presence of Broad-headed Snake scent. Sprint speeds of tailless and tailed Velvet Geckos were very similar over short (0.25 m) and longer distances (I m). During locomotor trials, geckos frequently stopped along the racetrack, but tail autotomy did not affect the frequency of this behavior. Contrary to our predictions, tailless Velvet Geckos did not decrease their activity levels in the presence of Broad-headed Snake scent. Overall, our data support the hypothesis that the locomotor costs associated with tail autotomy are relatively minor in lizard species where the tail plays no functional role in locomotion.

Several varieties of blue ballpoint pen inks were analysed by higher performance liquid chromatography (HPLC) and infrared spectroscopy (IR). The chromatographic data extracted at four wavelengths (254, 279, 370 and 400 nm)was analysed individually and at a combination of these wavelengths by the soft independent modeling of class analogies (SIMCA) technique using principal components analysis (PCA) to estimate the separation between pen samples. Linear discriminant analysis (LDA) measured the probability with which an observation could be assigned to a pen class. The best resolution was obtained by HPLC using data from all four wavelengths together, differentiating 96.4% pen pairs successfully using PCA and 97.9% pen samples by LDA> PCA separated 60.7% of the pen pairs and LDA provided a correct classification of 62.5% of the pends compared to IR. The need to develop a suitable IR method for analysing nlue ball-point pen inks has been emphasised and it is hoped that the development of such a method would indeed providea valuable tool for the non-destrictive analysis of blue ball-point pen ink samples for forensic purposes.

Danish district heating systems have good water quality, but continue to suffer from biofouling and biocorrosion. Localisation analyses of bacteria using microautoradiography were performed for one system in order to obtain detailed information for solving these problems. A mass balance showed that 77% of the bacteria were located at surfaces, with 23% in the bulk water, and 9% of the total carbon originated from biomass, while 91% was dissolved in the bulk water. The presence of active bacteria was determined with microautoradiography which showed that biofilms contained 99% and 1% were in the bulk water. A high bacterial functional diversity was observed, with active mesophilic and thermophilic bacteria under aerobic and anaerobic conditions and with potentially corrosive biofilm bacteria present. The study reveals that by applying the activity based approach, the ratio of living and dead bacteria in the biofilm and bulk water in this type of system could be accurately determined. Also, the results emphasise that to minimise biofilm growth and biocorrosion, monitoring should be established focusing on the surfaces, since bulk water parameters do not reflect bacterial activity.

The accuracy of nonlinear finite-difference time-domain (FDTD) methods is investigated by modeling nonlinear optical interaction in a ring resonator. We have developed a parallelized 3-D FDTD algorithm which incorporates material dispersion, (3)-nonlinearities and stair-casing error correction. The results of this implementation are compared with experiments, and intrinsic errors of the FDTD algorithm are separated from geometrical uncertainties arising from the fabrication tolerances of the device. A series of progressively less complex FDTD models is investigated, omitting material dispersion, abandoning the stair-casing error correction, and approximating the structure by a 2-D effective index model. We compare the results of the different algorithms and give guidelines as to which degree of complexity is needed in order to obtain reliable simulation results in the linear and the nonlinear regime. In both cases, incorporating stair-casing error correction and material dispersion into a 2-D effective index model turns out to be computationally much cheaper and more effective than performing a fully three-dimensional simulation without these features.

Ledovskikh, A, Danilov, D, Rey, WJJ & Notten, PHL 2006, 'Modeling of hydrogen storage in hydride-forming materials: Statistical thermodynamics', Physical Review B, vol. 73, no. 1. A new lattice gas model has been developed, describing the hydrogen storage in hydride-forming materials. This model is based on the mean-field theory and Bragg-Williams approximation. To describe first-order phase transitions and two-phase coexistence regions, a binary alloy approach has been adopted. A complete set of equations describing pressure-composition isotherms and equilibrium electrode potential curves of hydride forming materials in both solid-solution and two-phase coexistence regions has been set up. The proposed model defines both the equilibrium pressure and equilibrium potential as explicit functions of the normalized hydrogen concentration, using eight physically well-defined parameters. Gibbs free energies, entropies, and phase diagrams of both model (LaNiy Cu1.0) and commercial, MischMetal-based, AB5 -type materials at different compositions and temperatures have been simulated. Good agreement between experimental and theoretical results for the pressure-composition isotherms obtained in the gas phase and the equilibrium potential curves measured in electrochemical environment has been found in all cases. © 2006 The American Physical Society.

Empirical research on dimorphic plant species supports this hypothesis. To date, of 44 dimorphic angiosperms for which RA has been reported in the literature, RA is greater in females than males in 40 species, is equal in four, and in no species is it greater in males. 2 In many instances where differential RA occurs, sexual dimorphism in morphological or physiological traits has been reported. This dimorphism is often attributed to the differing costs of reproduction or to selection to counteract such costs. 3 We investigated RA and other morphological and physiological characters in Gynatrix pulchella, a dimorphic species that we found ranges from dioecious to subdioecious or gynodioecious, depending on season and locality. Our results showed that contrary to our predictions functionally male plants allocated significantly more biomass to reproduction than female plants across three populations. Greater male RA was due to a combination of larger, more numerous flowers and lower leaf biomass per branch than females. 4 There were no detectable costs of greater RA in males in terms of decreased overall growth or increased mortality. Additionally, leaf nitrogen content was greater in males than in females and there were no between-sex differences in gas exchange. 5 The finding that male plants allocate significantly more resources to reproduction than females in G. pulchella is apparently a unique case.

We have identified a second lin gene in a gene cassette. This cassette was recovered from a multiply antibiotic-resistant Salmonella enterica serovar Stanley strain (SRC54) isolated in 2001 from a traveler who had recently returned from Thailand.

It displayed intermediate resistance to ciprofloxacin. The gene cassette array was amplified by using standard primers (L2 and R1) in the 5' conserved sequence and 3' conserved sequence of class 1 integrons, and the 2.25-kb amplicon was cloned into pPCRscript and sequenced as previously described (see reference 6 for primer details). E. coli strain DH5{alpha} containing pPCR-Script with the cassette array was at least 10-fold more resistant to lincomycin (MIC, ?2,000 µg/ml) than DH5{alpha} containing only pPCR-Script (MIC, 180 µg/ml).

Recent research results confirm the importance of structural surface features of cathode materials for their electrochemical performance. Modification by coating is an important method to achieve improved electrochemical performance, and the latest progress was reviewed here. When the surface of cathode materials including LiCoO2, LiNiO2, LiMn2O4 and LiMnO2 is coated with oxides such as MgO, Al2O3, SiO2, TiO2, ZnO, SnO2, ZrO2, Li2O center dot 2B(2)O(3)-glass and other materials, the coatings prevent the direct contact with the electrolyte solution, suppress phase transition, improve the structural stability, and decrease the disorder of cations in crystal sites. As a result, side reactions and heat generation during cycling are decreased. Accompanying actions such as suppression of Mn2+ dissolution, increase in conductivity and removal of HF in electrolyte solutions have been observed. Consequently, marked improvement of electrochemical performance of electrode materials including reversible capacity, coulomb efficiency in the first cycle, cycling behavior, rate capability and overcharge tolerance has been achieved. In conclusion, further directions are suggested for the surface modification of electrode materials. With further understanding of the effects of the surface structure of cathode materials on lithium intercalation and de-intercalation, better and/or cheaper cathode materials from surface modification will come up in the near future.

Alien atom doping has been adopted to modify the electrochemical performance of olivine type LiFePO4 for cathode material of the lithium ion batteries. Here, we first report that zinc-doping can improve the performance of LiFePO4. The effects of zinc-doping have been studied by the measurements of X-ray diffraction pattern, scanning electronic microscopy, electrochemical impedance spectroscopy and cyclic voltammetry. The results indicate that the zinc atoms do not destroy the lattice structure of LiFePO4, and enlarge the lattice volume. During de-intercalation and intercalation process of lithium ions, the doped zinc atoms protect the LiFePO4 crystal from shrinking. This kind of "pillar" effect provides larger space for the movement of lithium ions. Consequently, the conductivity is enhanced and the lithium ion diffusion coefficient is boosted after doping. These favourable changes are beneficial to the improvement of the electrochemical performance of LiFePO4 including discharge capacity and rate capability.

Meanwhile, the kinetics of lithium intercalation and de-intercalation is greatly ameliorated.

A heuristic method for job shop scheduling based on decomposed due date to minimize total weighted tardiness is proposed. The initial due date of each operation is determined according to the flow allowance rate of each job, then the job sequences on all machines are obtained by the improved modified operation due date rule based on Giffler-Thompson scheme. And the due date of the critical operation is adjusted to improve the solution quality with considering interactions among jobs at each iteration. The simulation results show that the proposed method can obtain good solutions with acceptable computational efficiency, and can be used to the real job shop scheduling system.

Serum protein adsorption on colloidal silica surfaces was investigated using a quartz crystal microbalance with dissipation (QCM-D) monitoring. The amount of serum proteins adsorbed on colloidal silica-coated surfaces was not significantly different from the control silica surfaces, with the exception of 21 nm colloidal silica which experienced significantly less (P<0.05) fibrinogen adsorption compared with control silica. The adhesion and proliferation of human endothelial cells (C11STH) on nano-scale colloidal silica surfaces were significantly reduced compared with control silica surfaces, suggesting that the conformation of adsorbed proteins on the colloidal silica surfaces plays a role in modulating the amount of cell binding. Fibronectin is one of the main extracellular matrix proteins involved in endothelial cell attachment to biomaterial surfaces. There was reduced binding of a monoclonal anti-fibronectin antibody, that reacted specifically with the cell-binding fragment, to fibronectin-coated colloidal silica surfaces compared with control silica surfaces. This suggests that the fibronectin adsorbed on the colloidal silica-coated surfaces was conformationally changed compared with control silica reducing the availability of the cell-binding domain of fibronectin.

The quartz crystal microbalance with dissipation (QCM-D) (Q-Sense AB, Sweden) has been established as a useful tool for evaluating interactions between various biological and non-biological systems, and there has been increasing interest in using the QCM-D technique for cell monitoring applications. This study investigated the potential of the QCM-D to characterise the initial adhesion and spreading of cells in contact with protein precoated biocompatible surfaces. The QCM-D technique is attractive for monitoring cell adhesion and spreading as it allows in situ real-time measurements. The adhesion of NIH3T3 (EGFP) fibroblasts to tantalum (Ta) and oxidised polystyrene (PSox) surfaces precoated with serum proteins was examined using the QCM-D for a period of either 2 or 4 h. Time-lapse photography was performed at 30 min intervals to visually examine cell adhesion and spreading in order to relate cell morphology to the QCM-D response.

Lysozyme interaction with an acrylic-based hydrogel, poly(2-hydroxyethyl methacrylate) co-methacrylic acid (P(HEMA-MAA)), was investigated using a combination of quartz crystal microbalance with dissipation (QCM-D), surface plasmon resonance (SPR) and dual polarisation interferometry (DPI). This combination of techniques demonstrated that lysozyme initially absorbed into the hydrogel matrix and displaced water from the hydrogel while subsequent lysozyme additions were adsorbed onto the surface of the hydrogel material. QCM-D, being sensitive to bound water, showed an overall decrease in mass and stiffening of the layer after lysozyme addition. SPR, a water insensitive technique, showed a net mass increase after addition of lysozyme and buffer rinses. DPI showed that the first exposure of lysozyme to P(HEMA-MAA) was consistent with lysozyme absorption while subsequent lysozyme exposures were consistent with lysozyme adsorption.

Proteins, lipids and other biomolecules interact strongly with the acrylic-based biomaterials used for contact lenses. Although hydrogels are nominally resistant to protein fouling, many studies have reported considerable amounts of protein bound to poly(2-hydroxyethylmethacrylate) (PHEMA) lenses. This study examined the binding of a series of biomolecules (tear protein analogues, mucin and cholesterol) to poly(methylmethacrylate) (PMMA) and three HEMA-based hydrogels (PHEMA, HEMA plus methacrylic acid (P(HEMAMAA)), HEMA plus methacrylic acid plus N-vinylpyrrolidone (P(HEMAMAANVP))) by use of a quartz crystal microbalance with dissipation (QCM-D) monitoring. The QCM-D estimates changes in the mass and viscous constant for the adsorbed layer through measurements of frequency and dissipation.

The complex cis-[PtBr2{PPh2(4-catechol)}2] 1 has been synthesized by cleavage of the four methyl groups from cis-[PtCl2{PPh2(4-veratrole)}2] using BBr3, followed by work-up in the presence of excess bromide. An X-ray crystal structure of 1·(ethanol)2 confirms that the two catechol rings are adjacent to each other and approximately parallel, and therefore well structured to act as double bidentate ligands for adjacent metal atoms on the surface of a nanocrystal. The crystal packing of 1·(ethanol)2 involves intermolecular hydrogen-bonding interactions and a parallel fourfold phenyl embrace between PPh2 moieties. Density functional calculations have demonstrated that conformational variability of the aryl rings in cis-[PtBr2{PPh2(4-catechol)}2] is energetically feasible, and two conformations of cis-[PtBr2{PPh2(4-catechol)}2] as a complex ligand for Ti atoms on the various surfaces of the anatase and rutile structures of TiO2 have been assessed for geometrical commensurability. Three structural models for adsorbates of cis-[PtBr2{PPh2(4-catechol)}2] on TiO2 are developed for anatase (110), anatase (101), and rutile (001).

R44. BACKGROUND: Comparisons of complete bacterial genomes reveal evidence of lateral transfer of DNA across otherwise clonally diverging lineages. Some lateral transfer events result in acquisition of novel genomic segments and are easily detected through genome comparison. Other more subtle lateral transfers involve homologous recombination events that result in substitution of alleles within conserved genomic regions. This type of event is observed infrequently among distantly related organisms. It is reported to be more common within species, but the frequency has been difficult to quantify since the sequences under comparison tend to have relatively few polymorphic sites. RESULTS: Here we report a genome-wide assessment of homologous recombination among a collection of six complete Escherichia coli and Shigella flexneri genome sequences. We construct a whole-genome multiple alignment and identify clusters of polymorphic sites that exhibit atypical patterns of nucleotide substitution using a random walk-based method. The analysis reveals one large segment (approximately 100 kb) and 186 smaller clusters of single base pair differences that suggest lateral exchange between lineages. These clusters include portions of 10% of the 3,100 genes conserved in six genomes. Statistical analysis of the functional roles of these genes reveals that several classes of genes are over-represented, including those involved in recombination, transport and motility. CONCLUSION: We demonstrate that intraspecific recombination in E. coli is much more common than previously appreciated and may show a bias for certain types of genes. The described method provides high-specificity, conservative inference of past recombination events.

An established exposure-response relationship exists between water arsenic levels and skin lesions. Results of previous studies with limited historical exposure data, and laboratory animal studies suggest that diet may modify arsenic metabolism and toxicity. In this study, we evaluated the effect of diet on the risk of arsenic-related skin lesions in Pabna, Bangladesh. Six hundred cases and 600 controls loosely matched on age and sex were enrolled at Dhaka Community Hospital, Bangladesh, in 2001-2002. Diet, demographic data, and water samples were collected. Water samples were analyzed for arsenic using inductively coupled plasma mass spectroscopy. Betel nut use was associated with a greater risk of skin lesions in a multivariate model [odds ratio (OR)=1.67; 95% confidence interval (CI), 1.18-2.36]. Modest decreases in risk of skin lesions were associated with fruit intake 1-3 times/month (OR=0.68; 95% CI, 0.51-0.89) and canned goods at least 1 time/month (OR=0.41; 95% CI, 0.20-0.86). Bean intake at least 1 time/day (OR=1.89; 95% CI, 1.11-3.22) was associated with increased odds of skin lesions. Betel nut use appears to be associated with increased risk of developing skin lesions in Bangladesh. Increased intake of fruit and canned goods may be associated with reduced risk of lesions. Increased intake of beans may be associated with an increased risk of skin lesions. The results of this study do not provide clear support for a protective effect of vegetable and overall protein consumption against the development of skin lesions, but a modest benefit cannot be excluded.

Harmonization is a prctice whereby the harmoniser who is centered in silent prayer, opens and nourishes the subjects' chakrasm using touch. This technique has been widely used since 1983, with substantial anecdotal evidence wbout its benefits, but no published peer-reviewed data. This preliminary study aimed to discover if standard physiological measuring techniques can detect any significant changes in the central and autonomic nervous system and the cardiopulmonary system during harmonisation. A simple, comparative design was used, with one experimental group of 20 self-selecting, healthy women, naive to harmonisation. The results were compared with reference data, matched for age and gender, from non-intervention control studies conducted by the same experimeners in the same neurophysiological laboratory. An 80-minute recording session determined baseline, intervention and stabilisation measurements on electroencephalographic, electrocardiographic and respiratory data. A significant lowering of brain activity was found during theopening phase of harmonisation, implying a state of increased mental focus coupled with a sense of calmness and relaxation, while significant changes to heartbeat/respiration ratios were observed during the nourishing phase. This suggests that different physiological processes affecting the central and autonomic nervous system and the cardiopulmonary system may occur during different phases of harmonisation.

Growth and dominance of the cyanobacterium Anabaena circinalis in weir pools of the BarwonDarling River, Australia, are related to persistent vertical thermal stratification between October and March, when discharge is low. We determined critical velocities and discharges required to suppress bloom formation at three sites, and modelled the occurrence of sub-critical discharges in order to predict the frequency of blooms under different management scenarios. Our model suggests that the frequency of blooms was about double that expected under near-natural flows (without major impoundment or water extraction) for 19902000. Flow management, through Environmental Water Provisions that limit water extraction when river levels are low, has been in place since July 2000. Our model suggests that these provisions are unlikely to have had an effect on bloom frequency for 20002003. In the longer term, however, they could reduce bloom frequency at some sites by up to one-third Miura, T, Huete, A & Yoshioka, H 2006, 'An empirical investigation of cross-sensor relationships of NDVI and red/near-infrared reflectance using EO-1 hyperion data', REMOTE SENSING OF ENVIRONMENT, vol. 100, no. 2, pp. 223-236. Long term observations of global vegetation from multiple satellites require much effort to ensure continuity and compatibility due to differences in sensor characteristics and product generation algorithms. In this study, we focused on the bandpass filter differences and empirically investigated cross-sensor relationships of the normalized difference vegetation index (NDVI) and reflectance. The specific objectives were: 1) to understand the systematic trends in cross-sensor relationships of the NDVI and reflectance as a function of spectral bandpasses, 2) to examine/identify the relative importance of the spectral features (i.e., the green peak, red edge, and leaf liquid water absorption regions) in and the mechanism(s) of causing the observed systematic trends, and 3) to evaluate the performance of several empirical cross-calibration methods in modeling the observed systematic trends. A Level 1A Hyperion hyperspectral image acquired over a tropical forestsavanna transitional region in Brazil was processed to simulate atmospherically corrected reflectances and NDVI for various bandpasses, including Terra Moderate Resolution Imaging Spectroradiometer (MODIS), NOAA-14 Advanced Very High Resolution Radiometer (AVHRR), and Landsat-7 Enhanced Thematic Mapper Plus (ETM+). Data were extracted from various land cover types typically found in tropical forest and savanna biomes and used for analyses. Both NDVI and reflectance relationships among the sensors were neither linear nor unique and were found to exhibit complex patterns and bandpass dependencies.

AICAR (5-amino-1-β-d-ribofuranosyl-imidazole-4-carboxamide) is an adenosine analog which improves the recovery of the heart after ischemia. In some tissues AICAR enters cells and stimulates AMP-activated protein kinase (AMPK). We explored the mechanism of cardioprotection in isolated rat hearts. We confirmed that AICAR (0.5 mM) applied 10 min prior to a 30-min period of ischemia and present throughout ischemia and reperfusion caused a substantial improvement in the recovery of developed pressure on reperfusion. However, adenosine (100 μM) produced no improvement, suggesting that the mechanism of action of AICAR was not increased endogenous adenosine production. Measurements of intracellular sodium concentration ([Na+]i) showed that AICAR prevented the rapid rise of [Na+]i, which normally occurs on reperfusion. Inhibitors of the cardiac sodium-hydrogen exchanger (NHE1) also protect the heart from ischemic damage and also prevent the rapid rise of [Na+]i on reperfusion, suggesting that AICAR might cause the inhibition of NHE1. We tested this possibility on isolated rat ventricular myocytes in which the recovery of pHi after NH 4Cl exposure provides a measure of NHE1 activity. AICAR (0.5 μmM) inhibited NHE1 activity in response to an acid load by about 80%. To test whether the AICAR-induced inhibition of NHE1 arose through adenosine, we used the adenosine receptor blocker 8-sulfophenyltheophylline (8-SPT) and found that it had no measureable effect. To test whether the AICAR-induced inhibition of NHE1 might occur through the activation of AMPK, we measured the activity of two isoforms of AMPK. Surprisingly, activity was reduced, whereas in many other tissues AICAR increases AMPK activity. Furthermore, this effect of AMPK was blocked by 8-SPT, suggesting that the inhibition of AMPK arose through an adenosine-receptor-related pathway. We conclude that AICAR inhibits NHE1 through an unidentified pathway. This inhibition may make a contribution to the cardioprotective e...

We present a case study illustrating the challenges of analyzing accelerometer data taken from a sample of children participating in an intervention study designed to increase physical activity. An accelerometer is a small device worn on the hip that records the minute-by-minute activity levels throughout the day for each day it is worn. The resulting data are irregular functions characterized by many peaks representing short bursts of intense activity. We model these data using the wavelet-based functional mixed model. This approach incorporates multiple fixed-effects and random-effects functions of arbitrary form, the estimates of which are adaptively regularized using wavelet shrinkage. The method yields posterior samples for all functional quantities of the model, which can be used to perform various types of Bayesian inference and prediction. In our case study, a high proportion of the daily activity profiles are incomplete (i.e., have some portion of the profile missing), and thus cannot be modeled directly using the previously described method. We present a new method for stochastically imputing the missing data that allows us to incorporate these incomplete profiles in our analysis. Our approach borrows strength from both the observed measurements within the incomplete profiles and from other profiles, from the same child as well as from other children with similar covariate levels, while appropriately propagating the uncertainty of the imputation throughout all subsequent inference. We apply this method to our case study, revealing some interesting insights into children's activity patterns. We point out some strengths and limitations of using this approach to analyze accelerometer data.

The thermodynamic and kinetic properties of Pd-coated MgySc (1 - y) thin film electrodes are investigated. These thin film electrodes can be described as a two-layer structure, in which the Pd and MgySc(1 - y) layer contribute to the overall electrochemical response. In order to identify the response of the Pd layer in the two-layer system, thin films consisting of solely Pd, with identical thickness and orientation, were measured. Based on the fact that the chemical potentials of the individual layers of the Pd-coated MgySc (1 - y) thin films are equal at equilibrium, the exact hydrogen concentration in each layer could be determined. It is shown that during the major part of the hydrogen extraction process of the MgySc (1 - y) thin films, the composition of the Pd topcoat is close to PdH0.001. The kinetics of the surface reactions was investigated using electrochemical impedance spectroscopy and showed that, when cross-correlating the results of MgySc(1 - y) thin films (y = 0.65 - 0.85) and pure Pd films, the surface kinetics are completely dominated by the Pd topcoat. Additionally, it was shown that the charge transfer reaction, and not the absorption reaction is the rate-determining step. The impedance response, dominating the overall kinetic impedance at the hydrogen-depleted state, could be linked to the transfer of hydrogen across the Pd/MgySc(1 - y) interface in the two-layer thin film electrode. © 2005 Elsevier Ltd.

Deficiencies in apoptotic cell clearance have been linked to autoimmunity. Here we examined the time-course of peritoneal macrophage phagocytosis of dying cells following the direct injection of apoptotic thymocytes into the peritoneum of NOD mice and BALB/c controls. Macrophages from NOD mice demonstrated a profound defect in the phagocytosis of apoptotic thymocytes as compared to control macrophages. Nonobese diabetic mice also demonstrated a decrease in the clearance of apoptotic cell loads following an apoptotic stimulus to thymocytes (dexamethasone) when compared to BALB/c or NOR controls. Further, NOD mice demonstrated an increase in apoptotic cell load following an apoptotic stimulus to keratinocytes (ultraviolet light, UVB) when compared to control strains. Animals deficient in macrophage phagocytosis of apoptotic debris often manifest an autoimmune phenotype characterized by the production of antinuclear autoantibodies (ANA). We determined whether increased apoptotic cell loads (through repeated exposure to UVB irradiation) could accelerate such autoimmune phenomena in young NOD mice. Following repeated UVB irradiation, NOD mice, but not BALB/c or NOR controls, developed ANA. We propose that abnormalities in apoptotic cell clearance by macrophages predispose NOD mice to autoimmunity. Oliver, BG & Black, JL 2006, 'Airway Smooth Muscle and Asthma', Allergology International, vol. 55, no. 3, pp. 215-223. The airway smooth muscle is the key determinant of airway narrowing in asthma but its function in the absence of disease is unknown. Evidence for an intrinsic abnormality in the muscle in asthma is only just emerging. The airway smooth muscle is not merely a contractile cell, but also one which determines the composition of, and interacts with the extracellular matrix, and which may participate in inflammatory and allergic reactions and viral infections. The reason for the differences which have been observed in the in vitro properties of airway smooth muscle derived from asthmatic individuals may result from an inherent "supercontractility", an increased tendency to proliferate due to the absence of an inhibitory transcription factor C/EBP-α, the influence of an altered extracellular matrix and/or a decrease in release of factors such as PGE2 which would under normal circumstances inhibit both proliferation and contraction. Although long acting beta agonists and corticosteroids are successful treatments for inflammation and bronchoconstriction, the structural changes which constitute airway remodelling may require additional therapeutic intervention, the nature of which will be determined by thorough investigation of the mechanisms underlying the asthmatic phenotype. ©2006 Japanese Society of Allergology.

Laboratory study', WATER AIR AND SOIL POLLUTION, vol. 177, no. 1-4, pp. 59-80. Indoor air-borne loads of volatile organic compounds (VOCs) are usually significantly higher than those outdoors, and chronic exposures can cause health problems. Our previous laboratory studies have shown that the potted-plant microcosm, induced by an initial dose, can eliminate high air-borne VOC concentrations, the primary removal agents being potting-mix microorganisms, selected and maintained in the plant/root-zone microcosm. Our office field-study, reported in the preceding paper, showed that, when total VOC (TVOC) loads in reference offices (0 plants) rose above about 100 ppb, levels were generally reduced by up to 75% (to < 100 ppb) in offices with any one of three planting regimes. The results indicate the induction of the VOC removal mechanism at TVOC levels above a threshold of about 100 ppb. The aims of this laboratory dose-response study were to explore and analyse this response. Over from 5 to 9 days, doses of 0.2, 1.0, 10 and 100 ppm toluene and m-xylene were applied and replenished, singly and as mixtures, to potted-plants of the same two species used in the office study. The results confirmed the induction of the VOC removal response at the lowest test dosage, i.e in the middle of the TVOC range found in the offices, and showed that, with subsequent dosage increments, further stepwise induction occurred, with rate increases of several orders of magnitude. At each dosage, with induction, VOC concentrations could be reduced to below GC detection limits (< 20 ppb) within 24 h. A synergistic interaction was found with the binary mixtures, toluene accelerating m-xylene removal, at least at lower dosages. The results of these two studies together demonstrate that the potted-plant microcosm can provide an effective, self-regulating, sustainable bioremediation or phytoremediation system for VOC pollution in indoor air.

Using flow cytometry, two distinct populations of virus-like particles (VLP) and heterotrophic bacteria were defined within the 12 cm water layer immediately overlying healthy, diseased and dead acroporid corals. Bacterial abundances were similar in overlying water for all coral types, however, VLP were 30% higher above diseased corals than healthy or dead corals. Mean virus to bacteria ratios (VBR) were up to 30% higher above diseased corals than above healthy or dead coral or in distant water. Concomitant with increasing VLP concentrations within 5 cm of coral surfaces, VBR distributions were generally highest above healthy and diseased coral and depressed above dead coral. These results suggest fundamental shifts in the VLP and bacterial community in water associated with diseased corals.

We present a low temperature study of GaN eiplayers by means of low voltage cathodoluminescence (CL). We show that lowering the primary electrons accelerating voltage down to 1 kV allows imaging of single threading dislocations. By using monochromatic or panchromatic low voltage CL microscopy, it is possible to extract different diffusion lengths related to free excitons, bound excitons or donot-to-acceptor pair transitions.

We predict the scattering loss in rectangular high index-contrast waveguides, using a new variation of the classical approach of coupled-mode theory. The loss predicted by this three-dimensional (3-D) model is considerably larger than that calculated using previous treatments that approximate the true 3-D radiation modes with their two-dimensional counterparts. The 3-D radiation modes of the ideal waveguide are expanded in a series of cylindrical harmonics, and the coupling between the guided and radiation modes due to the sidewall perturbation is computed. The waveguide attenuation can then be calculated semianalytically. It is found that the dominant loss mechanism is radiation rather than reflection, and that the transverse electric polarization exhibits much larger attenuation than transverse magnetic polarization. The method also gives simple rules that can be used in the design of low-loss optical waveguides. The structural properties of sidewall roughness of an InGaAs/InP pedestal waveguide are measured using atomic force microscopy, and the measured attenuation is found to compare well with that predicted by the model.

Recent work on Neospora caninum, a protozoan parasite that causes abortion in dairy cattle has focused on a number of different control options. Modelling has suggested the most effective options for control but the present paper argues that the most effective option might not necessarily be optimal from an economic point of view. Decision trees, using published quantitative data, were contruscted to choose between four different control strategies. The costs of these interventions, such as 'test and cull', therapeutic treatment with a pharmaceutical, vaccination or "doing nothing" were compared, and modelled, in the first instacne on the New Zealand and Australian dairy situation. It is argued however, that the relative costs in toehr countries might be similar and that only teh availability of a registered vaccine will change the decision tree outcomes, as does the within-herd prevalence of N. caninum infection. To "do nothing" emerged as the optimal economic choice for n. caninum infections/abortions up to a within-herd prevalence of 18%, when viewed over a 1-year horizon, or 21% when costs were calculated over a 5 year horizon.

The microscale spatial distributions of viruses were investigated in three contrasting environments including oligotrophic open ocean, eutrophic coastal and estuarine habitats. The abundances of two discrete populations of both viruses and heterotrophic bacteria were measured at spatial resolutions of between 1 and 5 cm using purpose-designed microscale sampling equipment and flow cytometric sample analysis. Within open water samples, virus distributions were characterized by non-normal distributions and by `hotspots' in abundance where concentrations varied by up to 17-fold. In contrast to patterns generally observed at larger spatiotemporal scales, there was no correlation between bacterial and viral abundance or correspondence between bacteria and virus hotspots within these samples. Consequently, strong hotspots and gradients in the virus:bacteria ratio (VBR) were also apparent within samples. Within vertical pro¢les taken from above the sediment water interface within a temperate mangrove estuary, distributions of planktonic viruses were characterized by gradients in abundance, with highest concentrations observed within the 1-2 cm immediately above the sediment surface, and virus distributions were correlated to bacterial abundance (P50.01). The patterns observed in these contrasting habitats indicate that microscale patchiness of virus abundance may be a common feature of the marine environment. This form of heterogeneity may have important implications for virus^host dynamics and subsequently in£uence microbial trophodynamics and nutrient cycling in the ocean.

This study investigated DSM-defined anxiety symptoms in South African youths. Children and adolescents ( N = 701) from various cultural groups completed the SCARED and a questionnaire measuring perceived parental rearing behaviors. Results indicated that the psychometric properties of the SCARED were satisfactory in the total sample of South African youths, and acceptable in colored and black children and adolescents. Further, colored and black youths displayed higher SCARED scores than white youths, and there were also differences in the perceived parental rearing behaviors of the cultural groups. White youths generally rated their parents' rearing behaviors as less anxious, overprotective, and rejective, but more emotionally warm than colored and black youths. Finally, positive correlations were found between anxious rearing, overprotection, and rejection and anxiety symptoms. The clinical and research implications of these findings are briefly discussed. © 2005 Elsevier Ltd. All rights reserved.

The P2X7 receptor is a ligand-gated cation channel that is highly expressed on mononuclear leukocytes and that mediates ATP-induced apoptosis and killing of intracellular pathogens. There is a wide variation in P2X7 receptor function between subjects, explained in part by four loss-of-function polymorphisms (R307Q, E496A, I568N, and a 5′-intronic splice site polymorphism), as well as rare mutations. In this study, we report the allele frequencies of 11 non-synonymous P2X7 polymorphisms and describe a fifth loss-of-function polymorphism in the gene (1096C → G), which changes Thr357 to Ser (T357S) with an allele frequency of 0.08 in the Caucasian population. P2X7 function was measured by ATP-induced ethidium+ influx into peripheral blood lymphocytes and monocytes and, when compared with wild-type subjects, was reduced to 10-65% in heterozygotes, 1-18% in homozygotes, and 0-10% in compound heterozygotes carrying T357S and a second loss-of-function polymorphism. Overexpression of the T357S mutant P2X7 in either HEK-293 cells or Xenopus oocytes gave P2X7 function of ∼50% that of wild-type constructs. Differentiation of monocytes to macrophages, which also up-regulates P2X 7, restored P2X7 function to near normal in cells heterozygous for T357S and to a value 50-65% of wild-type in cells homozygous for T357S or compound heterozygous for T357S/E496A. However, macrophages from subjects that are compound heterozygous for either T357S/R307Q or T357S/stop codon had near-to-absent P2X7 function. These functional deficits induced by T357S were paralleled by impaired ATP-induced apoptosis and mycobacteria killing in macrophages from these subjects. Lymphocytes, monocytes, and macrophages from subjects homozygous for T357S or compound heterozygous for T357S and a second loss-of-function allele have reduced or absent P2X 7 receptor function. © 2006 by The American Society for Biochemistry and Molecular Biology, Inc.

Slender-bodied, diurnal "sand snakes" of the genus Psammophis are widespread and abundant through Africa, but the general biology of these animals remains poorly known. For example, sexual dimorphism is unstudied because it is difficult to determine the sex of live specimens (uniquely among snakes, the male hemipenis is vestigial). Our dissections of 700 preserved specimens provide detailed ecological information on ten psammophiine species from southern Africa. Males grow larger than females in most taxa, especially in species of large absolute body size. However, sex differences in body proportions (relative head size, relative tail length) are minor. Females produce small clutches (generally < 10 eggs), with larger clutches in larger females in some but not all species. Psammophylax tritaeniatus differs from the nine Psammophis species studied in its higher fecundity and its primary reliance on mammalian rather than reptilian prey. Within Psammophis, five species (P. brevirostris, P. jallae, P. leopardinus, P. subtaeniatus, P. trigrammus) fed mostly on scincid lizards, two (P. namibensis, P. notostictus) fed mostly on lacertid lizards, and two (P. trinasalis, P. mossambicus) took approximately equal numbers of lizards and mammals. Although dietary composition thus varied with snake species and body size, conspecific males and females took similar prey types. Thus, despite reports of unusual mating systems in captive psammophiines, these snakes exhibit only minor sexual dimorphism in size, bodily proportions, and dietary habits. Shine, R, Webb, JK, Lane, A & Mason, RT 2006, 'Flexible mate choice: a male snake's preference for larger females is modified by the sizes of females encountered', ANIMAL BEHAVIOUR, vol. 71, no. Part 1, pp. 203-209. Why do males exert strong mate choice in some taxa but not others? Theory suggests that mate discrimination will enhance male fitness when encounter rates with potential mates are high, when those potential mates vary in the fitness consequences likely to accrue from an attempted insemination, and when courting one female reduces the male's opportunity to court other females. One widespread form of mate choice involves a trend for males of many ectothermic species to court larger (and thus, more fecund) females. To test whether such preferences are dynamically adjusted to local conditions, we studied male preference for larger females in red-sided garter snakes, Thamnophis sirtalis parietalis, near a communal den in Manitoba, Canada. Courting a small female imposes a high opportunity cost for a male in the centre of the den, because many large and easily located females are nearby. In the surrounding woodland, in contrast, a male that neglects a small female is unlikely to encounter a larger substitute partner. In arena trials, male snakes from the den selected larger females more than did males from the surrounding woodland. Manipulating a den male's exposure to females (none, large, small) for 60 min led males to adjust their criteria for courtship depending upon the sizes of females encountered. Hence, the local environment can modify courtship criteria, with male garter snakes adjusting their mate choice selectivity based upon spatial and temporal factors that affect the opportunity costs of courtship.

We have developed an animal model to investigate the mechanisms underlying an acute exacerbation of chronic asthma. Sensitized BALB/c mice were exposed to aerosolized ovalbumin, either as chronic low-level challenge (mass concentration ≈ 3 mg/m3) for 4 wk, a single moderate-level challenge (≈ 30 mg/m3), or chronic low-level followed by single moderate-level challenge (the acute exacerbation group). Compared with animals receiving chronic challenge alone, mice in the acute exacerbation group exhibited a more marked inflammatory response, with involvement of intrapulmonary airways and lung parenchyma, and increased numbers of lymphocytes and eosinophils in bronchoalveolar lavage fluid. They also developed airway hyperreactivity (AHR) to methacholine, demonstrable as increased transpulmonary resistance and decreased compliance. This pattern of AHR was absent in chronically challenged animals, but was also present in animals given single moderate-level challenge. However, compared with animals receiving a single moderate-level challenge, inflammation and AHR were induced more rapidly in the acute exacerbation group. Eosinophil-deficient GATA1 Δdbl mice exhibited undiminished AHR in the acute exacerbation model. We conclude that in mice with pre-existing airway lesions resembling mild chronic asthma, exposure to a moderately high concentration of inhaled antigen induces features of an acute exacerbation. The inflammatory response involves distal airways and is associated with a distinct pattern of AHR, which develops independent of the enhanced eosinophilic inflammation.

Naturally occurring populations of bacteria and archaea are vital to life on the earth and are of enormous practical significance in medicine, engineering and agriculture. However, the rules governing the formation of such communities are still poorly understood, and there is a need for a usable mathematical description of this process. Typically, microbial community structure is thought to be shaped mainly by deterministic factors such as competition and niche differentiation. Here we show, for a wide range of prokaryotic communities, that the relative abundance and frequency with which different taxa are observed in samples can be explained by a neutral community model (NCM). The NCM, which is a stochastic, birthdeath immigration process, does not explicitly represent the deterministic factors and therefore cannot be a complete or literal description of community assembly. However, its success suggests that chance and immigration are important forces in shaping the patterns seen in prokaryotic communities.

The basic task of a battery management system (BMS) is the optimal utilization of the stored energy and minimization of degradation effects. It is critical for a BMS that the state-of-charge (SoC) be accurately determined. Open-circuit voltage (OCV) is directly related to the state-of-charge of the battery, accurate estimation of the OCV leads to an accurate estimate of the SoC. In this paper we describe a statistical method to predict the open-circuit voltage on the basis of voltage curves obtained by charging batteries with different currents. We employ a dimension reduction method (Karhunen-Loeve expansion) and linear regression. Results of our modelling approach are independently validated in a specially designed experiment. © 2005 Elsevier B.V. All rights reserved.

The year 2005 saw the opening of the new NEutron ReflectOmeter (NERO) at the GKSS research centre in Geesthacht, Germany for the investigation of magnetic and non-magnetic systems as well as soft matter nano-structures. NERO operates with a monochromatic beam of neutrons of wavelength 0.433 nm with a resolution better than 2%. An angular range of -20°<2θ<100° allows for both reflectometry and high-angle diffraction measurements to be made. NERO has both a position-sensitive detector and a pencil detector installed for flexibility when making specular and diffuse measurements. NERO has been designed to accommodate heavy-sample environments such as cryo-furnaces and various kinds of magnets. Polarization analysis is available for the investigation of magnetic nano-structures. A supermirror stack with a wide angular-acceptance range will be available in 2006 for time-efficient measurements of magnetic diffuse reflectivity.

Dientamoeba fragilis, an unusual single-celled parasite that was described first in 1918, is found worldwide in the gastrointestinal tract of humans. D. fragilis has emerged from obscurity recently because it is now recognised as a common cause of chronic diarrhoea abd is treatable with drugs. Recent molecular studies have described D. fragilis as having two genotypes. Diagnostic tests, based on conventional and real-time PCR, have been developed that will provide a rapid, sensitive and specific diagnosis of D. fragilis. These tests willalso aid the elucidation of the host distribution and the life cycle of this pathogen.

To the Editor: We report three cases of locally acquired Entamoeba histolytica infection in men who have sex with men (MSM) in Sydney, New South Wales. E. histolytica is an invasive pathogenic amoeba that can cause invasive intestinal and extraintestinal amoebiasis. Entamoeba dispar is morphologically identical but is considered non-pathogenic and non-invasive.1 The three patients presented with a 1â3-week history of diarrhoea and abdominal pain. Routine bacterial cultures were negative for pathogens. Ova, cyst and parasite investigations showed cysts and trophozoites of E. histolytica/dispar complex in permanently stained, fixed faecal smears. Stool samples were tested for E. histolytica and E. dispar by polymerase chain reaction (PCR), using a previously described method.2 All three patients were positive for E. histolytica by PCR; sequencing of the amplicons verified the presence of E. histolytica DNA.

This study examined the prevalence of dyspareunia, urinary sensory symptoms, and urinary incontinence and explored their associations among sexually active Chinese women aged 1534 years. Data from 3,150 women were analyzed from a survey undertaken during 2003 in 30 counties in China as part of the United Nations Population Fund Country Program. The overall prevalence of dyspareunia was 4.7%. Urinary pain, burning or frequency was reported by 8.5%, 6.2% reported urinary incontinence, and 2.3% reported both sets of urinary symptoms. The prevalence of urinary incontinence, both alone and in combination with sensory symptoms, increased in a linear manner with age. Dyspareunia was associated with early sexual debut, primary level of education, and membership of minority ethnic communities. Urinary sensory symptoms and incontinence were more common among those reporting early sexual debut, those with less schooling, and women engaged in agricultural and manual unskilled occupations. Urinary incontinence was more common among women who had had a previous vaginal delivery compared to nulliparous women. Dyspareunia was strongly associated with the presence of urinary symptoms, particularly among those with both sensory symptoms and incontinence (26.8%). Nearly a quarter of women who had dyspareunia had sought treatment but fewer had done so for urinary incontinence. Dyspareunia and urinary symptoms show distinct but overlapping patterns of association with demographic variables. The findings indicate unmet need for assessment and advice about these symptoms in womens reproductive health programs.

Photosynthetic electron transport directly generates the energy required for carbon fixation and thus underlies the aerobic metabolism of aquatic systems. We determined photosynthetic electron turnover rates, ETRs, from ca. 100 FRR fluorescence water-column profiles throughout the subtropical and tropical Atlantic during six Atlantic Meridional Transect cruises (AMT 6, MayJune 1998, to AMT 11, SeptemberOctober 2000). Each FRR fluorescence profile yielded a water-column ETR-light response from which the maximum electron turnover rate (ETRRCIImax), effective absorption (s PSII) and light saturation parameter (E k) specific to the concentration of photosystem II reaction centres (RCIIs) were calculated. ETRRCIImax and E k increased whilst s PSII decreased with mixed-layer depth and the daily integrated photosynthetically active photon flux when all provinces were considered together. These trends suggested that variability in maximum ETR can be partly attributed to changes in effective absorption. Independent bio-optical measurements taken during AMT 11 demonstrated that s PSII variability reflects taxonomic and physiological differences in the phytoplankton communities. ETRRCIImax and Ek, but not sPSII, remained correlated with mixed-layer depth and daily integrated photosynthetically active photon flux when data from each oceanic province were considered separately, indicating a decoupling of electron turnover and carbon fixation rates within each province. Comparison of maximum ETRs with 14C-based measurements of Pmax further suggests that light absorption and C fixation are coupled to differing extents for the various oligotrophic Atlantic provinces. We explore the importance of quantifying RCII concentration for determination of ETRs and interpretation of ETR-C fixation coupling.

The transmittance and irradiance distribution at the exit aperture of a cylindrical mirror light pipe (MLP) have been measured and calculated for the cases of collimated and diffuse inputs. MLPs are an example of a nonimaging optical system that can concentrate light, which may give rise to problematic hotspots and glare either on any diffuser used at the exit aperture or in the illuminated room. It is shown in this work that use of a diffuser at the entrance aperture overcomes these problems without a marked reduction in transmission of a typical MLP.

The resolution of secondary electron (SE) images in scanning electron microscopy (SEM) is limited by the SE diffusion length. However, most materials are poor electrical conductors and in practice, resolution and image information content are often limited by charging. We demonstrate how charging can be eliminated as the resolution-limiting factor using a gaseous SE detector for magnetic immersion electron lenses. Charging is stabilized by ions produced in a magnetic field-assisted gas ionization cascade. The charge control self-regulation process does not quench the SE imaging signal, thereby enabling high resolution image contrast mechanisms that are suppressed in high vacuum SEM. © 2006 American Institute of Physics.

The ability of corals to cope with environmental change, such as increased temperature, relies on the physiological mechanisms of acclimatisation and long-term genetic adaptation. We experimentally examined the bleaching sensitivity exhibited by 2 species of coral, Pocillopora damicornis and Turbinaria reniformis, at 3 locations across a latitudinal gradient of almost 6 degrees on the Great Barrier Reef (GBR), Target bleaching temperature was reached by using a ramping rate of 0.2 degrees C/h. We found that the bleaching sensitivity and recovery of both species differed between corals with clade D symbionts and those with clade C. However, in F damicornis bleaching susceptibility corresponded more strongly with latitude than with zooxanthella type and hence, temperature history, suggesting that local adaptation has occurred. The observed bleaching sensitivity was shown by a decrease in photochemical efficiency (F-v/F-m) in both species of coral. The rate of recovery in T reniformis was highest in explants containing clade D symbionts. The occurrence of clade D in the northern section of the GBR may reflect a long-term response to high sea water temperatures, while the presence of clade D in low abundance in T reniformis at Heralds Prong Reef and Percy Island may be a result of recent bleaching events.

Oxysterols are the 27-carbon products of cholesterol by both enzymic and non-enzymic mechanisms. Their roles in cholesterol homeostasis, as well as in diseases in which oxidative damage and lipid peroxidation are implicated (e.g. atherosclerosis), have been investigated extensively. However, there are a number of important considerations regarding the chysiological/pathophysiological functions and activities of the different oxysterols. First,in both normal and diseased tissues, the levels of oxysterols are very low when compared to the native sterol. Also, when assessing studies thathave measured the levels of oxysterols in biological samples, there must be careful consideration as to the method of sample isolation,s torage and sampling. This is because of the potential generation or loss of oxysterols during these procedures. Additionally, the relevance of in vitro studies which examine the effects of oxysterols upon cell function should be judged as to cellular oxysterol content (both in terms of the levels of oxysterol and the degree of esterification) resulting fromthe oxysterol treatment. We present evidence that the means by which oxysterol is delivered in vitro determines whether the oxyterol content reflects what has been found in vivo. Studies identifying the specific cellular targets of oxysterol indicate that several oxysterols may be regulators of cellular lipid metabolism via control of gene transcription.

Recently, a lattice gas model was presented and successfully applied to simulate the absorption/desorption isotherms of various hydride-forming materials. The simulation results are expressed by parameters corresponding to several energy contributions, e.g., interaction energies. However, the use of a model system is indispensable in order to show the strength of the simulations. The palladium-hydrogen system is one of the most thoroughly described metal hydrides found in the literature and is therefore ideal for this purpose. The effects of decreasing the thickness of Pd thin films on the isotherms have been monitored experimentally and subsequently simulated. An excellent fit of the lattice gas model to the experimental data is found, and the corresponding parameters are used to describe several thermodynamic properties. It is analyzed that the contribution of H-H interaction energies to the total energy and the influence of the host lattice energy are significantly and systematically changing as a function of Pd thickness. Conclusively, it has been verified that the lattice gas model is a useful tool to analyze thermodynamic properties of hydrogen storage materials. © 2006 American Chemical Society. Vermeulen, P, Niessen, RAH & Notten, PHL 2006, 'Hydrogen storage in metastable MgyTi(1−y) thin films', Electrochemistry Communications, vol. 8, no. 1, pp. 27-32. The electrochemical properties of MgyTi(1 - y) thin films with y ranging from 0.50 to 0.95 during (de)hydrogenation are investigated. These metastable alloys were successfully prepared by means of electron-beam deposition at room temperature. X-ray diffraction confirmed that crystalline single-phase materials were obtained. Galvanostatic dehydrogenation measurements show that substituting Mg by Ti clearly affects the hydrogen storage properties. MgyTi(1 - y) alloys with less than 20 at.% Ti exhibit an extremely low rate-capability, whereas increasing the Ti-content leads to a enhanced rate-capability. A superior reversible hydrogen storage capacity, along with an excellent rate-capability, is found for the Mg0.80Ti0.20 alloy. To obtain a comprehensive view of the effect of Ti on the electrochemical hydrogen storage properties, pure Mg thin films are also included in the present study. The electrochemical deep-discharging behaviour of pure Mg shows a distinct evolution of the overpotential which might be due to a nucleation and growth process. Galvanostatic hydrogenation of the MgyTi(1 - y) alloys revealed the formation of products that do not correspond to the intrinsic thermodynamic properties of the individual Mg and Ti hydride, suggesting that no segregation occurs. Moreover, the close analogy of the electrochemical behaviour of MgyTi(1 - y) and MgySc (1 - y) alloys points to a fcc-structured hydride. © 2005 Elsevier B.V. All rights reserved.

Many animals autotomize their tails to facilitate escape from predators. Although tail autotomy can increase the likelihood of surviving a predatory encounter, it may entail subsequent costs, including reduced growth, loss of energy stores, a reduction in reproductive output, loss of social status and a decreased probability of survival during subsequent encounters with predators. To date, few studies have investigated the potential fitness costs of tail autotomy in natural populations. I investigated whether tail loss influenced survival, growth and territory occupation of juvenile velvet geckos Oedura lesueurii in a population where predatory snakes were common. During the 3-year mark-recapture study, 32% of juveniles voluntarily autotomized their tails when first captured. Analysis of survival using the program MARK showed that voluntary tail autotomy did not influence the subsequent survival of juvenile geckos. Survival was age-dependent and was higher in 1-year-old animals (0.98) than in hatchlings (0.76), whereas recapture probabilities were time-dependent. Growth rates of tailed and tailless juveniles were very similar, but tailless geckos had slow rates of tail regeneration (0.14 mm day(-1)). Tail autotomy did not influence rock usage by geckos, and both tailed and tailless juveniles used few rocks as diurnal retreat sites (means of 1.64 and 1.47 rocks, respectively) and spent long time periods (85 and 82 days) under the same rocks. Site fidelity may confer survival advantages to juveniles in populations sympatric with ambush foraging snakes. My results show that two potential fitness costs of tail autotomy - decreased growth rates and a lower probability of survival - did not occur in juveniles from this population.

Webb, JK, Shine, R & Christian, KA 2006, 'The adaptive significance of reptilian viviparity in the tropics: Testing the maternal manipulation hypothesis', EVOLUTION, vol. 60, no. 1, pp. 115-122. Phylogenetic transitions from oviparity to viviparity in reptiles generally have occurred in cold climates, apparently driven by selective advantages accruing from maternal regulation of incubation temperature. But why, then, are viviparous reptiles so successful in tropical climates? Viviparity might enhance fitness in the tropics via the same pathway as in the temperate zone, if pregnant female reptiles in the tropics maintain more stable temperatures than are available in nests (Shine's maternal manipulation hypothesis). Alternatively, viviparity might succeed in the tropics for entirely different reasons than apply in the temperate zone. Our data support the maternal manipulation hypothesis. In a laboratory thermal gradient, pregnant death adders (Acanthophis praelongus) from tropical Australia maintained less variable body temperatures (but similar mean temperatures) than did nonpregnant females. Females kept at a diel range of 25-31 degrees C (as selected by pregnant females) gave birth earlier and produced larger offspring (greater body length and head size) than did females kept at 23-33 degrees C (as selected by nonpregnant snakes). Larger body size enhanced offspring recapture rates (presumably reflecting survival rates) in the field. Thus, even in the tropics, reproducing female reptiles manipulate the thermal regimes experienced by their developing embryos in ways that enhance the fitness of their offspring. This similarity across climatic zones suggests that a single general hypothesis-maternal manipulation of thermal conditions for embryogenesis-may explain the selective advantage of viviparity in tropical as well as cold-climate reptiles.

While it is well established that viruses play an important role in the sturcture of marine microbisal food webs, few studies have directly addresed their role in large lake systems. As part of an ongoing study of the microbial acology of Lake Erie, we have examined the distribution and diversity of viruses in this system. One surprising result has bee the pervasive distribution of cyanophages that infect the marine cyanobacterial isolate Synechococcus sp. strain WH7803. Viruses that typically infect this cyanobacterium wre identified throughout the western basin of Lake Erie, as well as in locations within the central and eastern basins. Analyses of the gene encoding the g20 viral capsid assembly protein (a conservative phylogenetic marker for the cyanophage) indicate that these viruses as well as amplicons from natural populations and the ballast of commercial ships are related to marine cyanophages but in some cases form a unique clade, leaving questions concerning the native hosts of these viruses. The results suggest that cyanophages may be as important in freshwater systems as they are known to be in marine systems.

An extensive body of research documents the high prevalence of comorbidity among child and adolescent disorders in general and between conduct problems and depression in particular. These problems co-occur at significantly higher rates than would be expected by chance and their comorbidity may have significant implications for nosology, treatment, and prognosis. Four main hypotheses have been put forth to account for these high rates of comorbidity. First, comorbidity may be a result of shortcomings associated with referral or informant biases. Second, comorbidity may be an artifact of overlapping definitional criteria. Third, one disorder may cause the other disorder by influencing the developmental trajectory and placing an individual at increased risk for further difficulties. Finally, comorbidity between two disorders may be explained by shared underlying causal or risk factors. The purpose of this review is to explore these possibilities, concentrating primarily on the common risk factors of parent psychopathology, emotion regulation, and cognitive biases that may underlie the co-occurrence of these two disorders. Based on our review, we propose a model for the development of comorbidity between these two disorders. © Springer Science+Business Media, LLC 2006.

Office field-study', WATER AIR AND SOIL POLLUTION, vol. 175, no. 1-4, pp. 163-180. Volatile organic compounds (VOCs) are major contaminants of indoor air, with concentrations often several times higher than outdoors. They are recognized as causative agents of "building-related illness" or "sick-building syndrome". Our previous laboratory test-chamber studies have shown that the potted-plant/root-zone microorganism microcosm can eliminate high concentrations of air-borne VOCs within 24 hours, once the removal response has been induced by an initial dose. However, the effectiveness of the potted-plant microcosm in 'real-world' indoor spaces has never previously been tested experimentally. This paper reports the results of a field-study on the effects of potted-plant presence on total VOC (TVOC) levels, measured in 60 offices (12 per treatment), over two 5-9 week periods, using three planting regimes, with two 'international indoor-plant' species. Fourteen VOCs were identified in the office air. When TVOC loads in reference offices rose above 100 ppb, large reductions, of from 50 to 75% (to <100 ppb), were found in planted offices, under all planting regimes The results indicate that air-borne TVOC levels above a threshold of about 100 ppb stimulate the graded induction of an efficient metabolic VOC-removal mechanism in the microcosm. Follow-up laboratory dose-response experiments, reported in the following paper, confirm the graded induction response, over a wide range of VOC concentrations. The findings together demonstrate that potted-plants can provide an efficient, self-regulating, low-cost, sustainable, bioremediation system for indoor air pollution, which can effectively complement engineering measures to reduce indoor air pollution, and hence improve human wellbeing and productivity.

The recent observation of a powerlaw relationship, S ? Az, between number of taxa, S, and area, A, for microbial eukaryotes and bacteria suggests that this is one of the few generic relationships in ecology, applicable to plants, animals and microbes. However, the rate of increase in the number of species with area varies from approximately the fourth (z = 0.26) to as little as the 50th root (z = 0.0019) in microbes. This is an enormous range for which no quantitative explanation has been proffered. We show by sampling from synthetic populations that the disparity between sample and community sizes in microbial community surveys means z can be considerably underestimated and accrual of rare taxa with increasing area will not be detectable. Significant microbial taxaarea relationships will only be observed when changes in community structure within samples correlate with area. Thus, the very low z values observed recently cannot be used as the sole evidence in support of any particular community theory of community assembly. More generally, this suggests that our search for patterns and laws in the microbial world will be profoundly influenced and, potentially distorted by the sample sizes that are typical of microbial community surveys.

The unique optical properties of gold nanorods, which exhibit tuneable absorption asa function of their aspect ratio, suggest that they might have potential applications in coatings for solar control on windows. Here we explore the properties of coatings produced by attaching gold nanorods to the surface of glass. Such coatings can attenuate solar radiation effectively, even at very low gold contents, but the figure-of-merit of our experimental coatings was close to unit, indicating that theyr are not spectrally selective. however, calculations are presented to show how coatings comprised of a blend of rods with aspect ratios of greater than 3 can produce coatings of up to 1.4. The maximum avlue possible for perfectly spectrally-selective coating in sunlight is 2.08. Unfortunately, the practical realisation of such coatings requires the further development of reliable methods to scale up the production of gold nanorods of longer aspect ratios.

The discovery of small 'non-coding' RNA molecules (small interfering (si)- and micro-RNAs) that regulate the function of a gene or clusters of genes and the design of synthetic analogues of these molecules may provide new directions for the treatment and characterization of respiratory disorders. © 2006 Elsevier Ltd.

An algorithm based on cluster decomposition is presented for large scale WCDMA base station positioning problem. A data matrix based on the signal gain of cellular networks and some criterion functions are designed for K means clustering. In the algorithm, the original problem is firstly decomposed into K sub-problems by K means clustering. Each sub-problem is then solved by integer programming. Finally, the solutions of K sub-problems are coordinated to form an approximate solution of the global problem. Simulation result shows the validity of this algorithm.

Linear mixed models are able to handle an extraordinary range of
complications in regression-type analyses. Their most common use is to account
for within-subject correlation in longitudinal data analysis. They are also the
standard vehicle for smoothing spatial count data. However, when treated in
full generality, mixed models can also handle spline-type smoothing and closely
approximate kriging. This allows for nonparametric regression models (e.g.,
additive models and varying coefficient models) to be handled within the mixed
model framework. The key is to allow the random effects design matrix to have
general structure; hence our label general design. For continuous response
data, particularly when Gaussianity of the response is reasonably assumed,
computation is now quite mature and supported by the R, SAS and S-PLUS
packages. Such is not the case for binary and count responses, where
generalized linear mixed models (GLMMs) are required, but are hindered by the
presence of intractable multivariate integrals. Software known to us supports
special cases of the GLMM (e.g., PROC NLMIXED in SAS or glmmML in R) or relies
on the sometimes crude Laplace-type approximation of integrals (e.g., the SAS
macro glimmix or glmmPQL in R). This paper describes the fitting of general
design generalized linear mixed models. A Bayesian approach is taken and Markov
chain Monte Carlo (MCMC) is used for estimation and inference. In this
generalized setting, MCMC requires sampling from nonstandard distributions. In
this article, we demonstrate that the MCMC package WinBUGS facilitates sound
fitting of general design Bayesian generalized linear mixed models in practice.

An electrochemical method has been developed for the in situ determination of concentration gradients in the electrolyte of sealed Li-ion batteries by measuring the potential difference between microreference electrodes. Formulas relating the concentration gradient and the potential difference between the microreference electrodes were derived from the Nernst-Planck equation. The concentration gradients in Li-ion batteries are theoretically and experimentally proven to be linear at steady state under galvanostatic charging and discharging conditions. Based on this finding, both the diffusion coefficient of the lithium ions in the electrolyte and the diffusion overpotential related to the concentration gradient have been calculated. It was found that the concentration gradient is proportional to the applied current over a wide current range and that the obtained diffusion coefficient of lithium ions is almost constant. For the batteries studied in this work, the diffusion overpotential is already noticeable at 0.30 A and the limiting current is estimated to be 1.1 A, corresponding to a C-rate of 3.7. © 2006 Wiley-VCH Verlag GmbH & Co.

A bottleneck-based decomposition heuristic algorithm is proposed for dealing with computational complexity in large-scale flow shop scheduling problems. Based on the characteristic of bottleneck, the flow shop is decomposed into bottleneck and non-bottleneck machines. A single-machine scheduling problem with release time and delivery time is built for the bottleneck machine, which is solved optimally, while simple priority rules are used for scheduling the non-bottlenecks. The correlations between the bottleneck and non-bottleneck machines are coordinated by adjusting the release time and delivery time of jobs on the bottleneck machine. Simulation results show that the heuristic algorithm can obtain better solution in quite short time and be suitable to large-scale problems.

Single-vein leaves have the simplest hydraulic design possible, yet even this linear water delivery system can be modulated to improve physiological performance. We determined the optimal distribution of transport capacity that minimizes pressure drop per given investment in xylem permeability along the needle for a given length without a change in total water delivery, or maximizes needle length for a given pressure difference between petiole and needle tip. This theory was tested by comparative analysis of the hydraulic design of three pine species that differ in the length of their needles [ Pinus palustris (Engl.) Miller, ¡« 50 cm; Pinus ponderosa Lawson & Lawson, ¡« 20 cm and Pinus rigida Miller, ¡« 5 cm]. In all three species, the distribution of hydraulic permeability was similar to that predicted by the optimum solution. The needles of P. palustris showed an almost perfect match between predicted and actual hydraulic optimum solution, providing evidence that vein design is a significant factor in the hydraulic design of pine leaves.

In this paper we compare tje optical absorption for nanospheres made from a range of transition and alkali metals from li (A=3) to Au (A=79). numerical solutions to Mie theory were used to claculate the absorption efficiency for nanospheres varying in radii between 5nm and 100 nm in vacuum. We show that although gold is the most commonly used nanoparicle material, its absorption efficiency at the lasmon resonance is not as strong as materials such as the alkali metals. Of all the materials tried, potassium spheres with a radius of 21 nm have an optimum absorption efficiency of 14.7. in addition we also show that, unlike gold, the wavelength of the plasmon peak in other materials is sensitive to the sphere radius. In potassium the peaporition shifts by 100 nm for spheres ranging from 5 nm to 65 nm, the shift is less than 10 nm for gold spheres.

Event-driven uncertainties such as corporate defaults, operational failures or central bank announcements are important elements in the modelling of financial quantities. Therefore, stochastic differential equations (SDEs) of jump-diffusion type are often used in finance. We consider in this paper weak discrete time approximations of jump-diffusion SDEs which are appropriate for problems such as derivative pricing and the evaluation of risk measures. We present regular and jump-adapted predictor-corrector schemes with first and second order of weak convergence. The regular schemes are constructed on regular time discretizations that do not include jump times, while the jump-adapted schemes are based on time discretizations that include all jump times. A numerical analysis of the accuracy of these schemes when applied to the jump-diffusion Merton model is provided.

Using the discrete dipole approximation (DDA) the local electromagnetic fields surrounding gold nano-cap particles are investigated. Suitable k-vectors and polarization vectors of the incident light are used to determine the largest local electric field enhancement. The largest enhancement can be found for the 864 nm dipole resonance; where the field enhancement is approximately 30000 times the applied field. The electric field contours surounding the particle are used to assign the order of the surface plasmon resonance.

Gold nanorods manifest a tunable plasmon resonance with light in the visible to near-infrared regions of the spectrum, and have been proposed for use in spectrally selective coatings on glass. however, details of shape and packing density have a significant effect onthe optical properties of these nanoparticle coatings. Here we show how these effects can be controlled and exploited to produce a flexible spectral response.

A nano- or- mesoporous sponge of Au is formed when the intermetallic compound AuAl2 is de-alloyed with NaOH. The large specific surface area of the sponge, and the unique surface chemical properties of Au indicate that this porous material might suefully serve as an electrode in capacitive sensors or other specialised electrochemical cells. Results for some prototype sensor and emergy storage systems are presented, and methods of controlling the nature of the porosity presented.

The geometry and energetics for adsorption of ethynylbenzene on au(!!!) have been studied using Density Functional Theory. The alkynyl group, following removal of the terminal H atom, adsorbs covalently to the surface in the fcc hollow site with a bond energy of about 70 kcal.mol-1. Intermediate adsorption states are also possible via a hydrogen 1,2 shoft to form a surface-bound vinylidene, or through the opening o the c-c triple bond without removing the hydrogen atom.

We perform emperical calculations of the tunneling current through various small organic molecules sandwiched between gold electrodes by using the Wenzel-Kramers-Brillouin (WKB) approximation. The barrierto tunneling is taken to eb the work function of gold and calculated from a first principles electronic structure code. The current-voltage characteristics of these molecules are compared in the context of exisiting first principles and experimental results. In this model the surface dipole moment, induced by the adsorbed molecule can have asignificant effect on the current and hence dipole moments may be an important property for prediction of the conductance chracteristics of a molecule.

We discuss various possibilities to design phase shifters with reduced frequency dispersion using combined sections of forward-wave and backward-wave transmission lines. It is shown that inclusion of backward-wave sections into a single transmission line always increases the total dispersion. On the other hand, we show that dispersion can be reduced by means of lines with positive anomalous dispersion and provide an example of such line. Furthermore, we report the theory and design of a novel phase shifter, based on parallel combined backward-forward transmission lines. The phase shifts, produced by this device, are characterized with negligible frequency dependence in a wide frequency range. We show that for an ideal performance, phase deviation can be less than 1° within a 20% bandwidth while excellent impedance matching is retained. We support these theoretical estimates by microwave circuit simulations and direct measurements, showing that the novel phase shifter can be easily implemented with simple electronic components. © 2006 EuMA.

The potential use of Fe doped GaN for spintronics applications requires a complete understanding of the electronic structure of Fe in all of its charge states. To address these issues, a set of 400 μm thick freestanding HVPE grown GaN:Fe crystals with different Fe-concentration levels ranging from 5×1017 cm-3 to 2×1020 cm -3 was studied by means of photoluminescence, photoluminescence excitation (PLE) and Fourier transform infrared (FTIR) transmission experiments. The Fe3+/2+ charge transfer (CT) level was determined to be at 2.86 ± 0.01 eV above the valence band maximum considerably lower than the previously reported value of 3.17 ± 0.10 eV. A bound state of the form (Fe2+, hVB) with a binding energy of 50 ± 10 meV has been established as an excited state of Fe3+. FTIR transmission measurements revealed an internal (5E - 5T2) transition of Fe2+ around 400 eV which, until now, was believed to be degenerate with the conduction band. Consequently, a second CT band was detected in PLE spectra. © 2006 Materials Research Society.

We report an advanced phase compensation principle, which employs combined backward-forward transmission lines having similar frequency dispersion. Various applications of this principle to the design of microwave devices allow for an exceptionally low dispersion in a wide frequency range while keeping the structure very compact and simple compared to conventional solutions. To illustrate the idea, we present the performance of (i) phase shifters, (ii) power dividers and (iii) baluns (complete antenna feeders) built on the reported principle. We support the theoretical estimates by microwave circuit simulations and direct measurements, showing that the novel devices can be easily implemented with simple electronic components.

This paper aims to discuss the optimal selection of investments for the short and long run in a continuous time financial market setting. First, it documents the almost sure pathwise long-run outperformance of all positive portfolios by the growth optimal portfolio. Secondly, it assumes that every investor prefers more rather than less wealth and keeps the freedom to adjust his or her risk aversion at any time. In a general continuous market, a two fund separation result is derived which yields optimal portfolios located on the Markowitz efficient frontier. An optimal portfolio is shown to have a fraction of its wealth invested in the growth optimal portfolio and the remaining fraction in the savings account. The risk aversion of the investor at a given time determines the volatility of her/his optimal portfolio. It is pointed out that it is usually not rational to reduce risk aversion further than is necessary to achieve the maximum growth rate. Assuming an optimal dynamics for a global market, the market portfolio turns out to be growth optimal. The discounted market portfolio is shown to follow a particular time transformed diffusion process with explicitly known transition density. Assuming that the drift of the discounted market portfolio grows exponentially, a parsimonious and realistic model for its dynamics results. It allows for efficient portfolio optimisation and derivative pricing.

View description>>
The pricing and hedging of long dated derivative contracts is a challenging area of research. As a result of utility indifference pricing for general payoffs the growth optimal portfolio turns out to be the appropriate numeraire or benchmark with the real world probability measure as corresponding pricing measure. This concept of real world pricing can be applied for valuing long dated derivatives. An equivalent risk neutral probability measure does not need to exist under this benchmark approach. This paper develops a parsimonious model for a stock index dynamics, which is based on a time transformed squared Bessel process. It uses a diversified world stock index as proxy for the growth optimal portfolio. Surprisingly low prices result for long dated zero coupon bonds that can be replicated using historical data. Such prices and hedges are difficult to explain under the prevailing risk neutral approach.

A variety of fluorescent and chromophoric proteins homologous to the green fluorescent protein (GFP) has been recently discovered and cloned from non-bioluminescent marine animals, such as corals, and now provide a multitude of colors for use in fluorescence imaging applications. Recently, a novel fluorescence imaging methodology has emerged that utilizes the unique photoactivatory property of several GFP-like proteins, which respond to irradiation by altering their optical properties, thereby providing a new spatio-temporal capability to the GFP-based imaging applications. During our studies of GFP-like proteins from the Great Barrier Reef corals, several novel photoactivatable (PA) GFP-like proteins have been discovered. These include fluorescence photo-amplifiers and reversible photoswitchers, similar to PA jelly-fish derived PA-GFP and Dronpa, that greatly increase their emissions following ultraviolet-A (UVA) irradiation; the red-to-green (R-to-G) converters, similar to DsRed, that rapidly change to green color following single- or 2-photon irradiation; the green-to-red (G-to-R) converters, that acquire bright red fluorescence following UV-violet irradiation, similar to Kaede-like proteins; and the kindling GFP-like proteins, that are non fluorescent, but rapidly acquire bright fluorescence after green light irradiation. We report on the various optical characteristics of these coral PA proteins that may be used to expand the scope of the available fluorescence bio-imaging technologies.

The techniques used to identify nanoparticle size and shape characteristics are o vital importance in the developemnt of functional nanoparticles. Each technique offers different advantages: this work compares the two techniques of transmission electron microscopy (TEM) and x-ray diffraction (XRD) analysis by charactering CeO2 nanoparticle specimens. Whole Powder Pattern Modelling (WPPM) is used to quantify the specimens dislocations and size characteristics from XRD data. Using admixed samples we test and extend the techniques. We show that XRD accurately characterises small crystallite distributions and that larger crystallite distributions necessitate further investigation.

It is shown that the linewidth-enhancement α-factor in a semiconductor optical amplifier (SOA) has a significant temporal dependence. A time window with a small or even a negative α-factor is observed both in experiments and in calculations. This observation might seriously impact the performance of XPM devices at highest speed. © 2006 Optical Society of America.

We present examples of ordered assemblies of organic and biological molecules on gold(111) surfaces. The first example shows how control over mono or multilayer assemblies of 1,4-phenylenedimethanthiol can be achieved and monitored. The second example shows how monolayers on gold can be prepared using amine groups to anchor aromatic molecules to the surface. A third example whos how ordered assemblies of genetically-engineered inorganic-binding polypeptides can be formed on gold surfaces using a 3-repeat, 14 amino acid gold-binding protein (GBP1).

INTRODUCTION 'Motorway service stations exist to meet a road safety need by giving drivers somewhere to stop and rest' Lord Whitty. From analyses of road crash investigation reports on a total of over 2,000 roadtraffic collision (RTC) files obtained from UK police forces, we have found that sleepiness is a major cause of serious accidents on monotonous roads in Great Britain, especially motorways. Moreover, compared with RTCs as a whole, we have found that sleep-related crashes (SRCs) are more likely to result in death or serious injury. We have also shown that STATS19 has not been a reliable source of information on SRCs, and we have developed other techniques for identifying them. These techniques are now adopted by over half the police forces and have been successfully 'tested' in many court cases involving death by dangerous driving. Our analyses of SRCs, on behalf of the Department for Transport (DfT), have been the basis of road-crash audits that have also examined the influence of: time of day, day of week, type of driver, road lighting versus no lighting, road-traffic density (e.g. 'Sleep related vehicle accidents on sections of selected trunk roads and motorways in the UK, 1995-1998' - DfT Road Safety Report No. 22, 2001). In these respects, we have found, for example, that in relation to traffic flow rates, proportionately many more SRCs happen during the hours of midnight to 0600h and, typically, drivers causing SRCs are men, usually aged under 30 years. We have also conducted laboratory studies of the processes of falling asleep at the wheel using a realistic, interactive and fully instrumented driving simulator that enables us to monitor and analyse automatically a variety of driving behaviours, as well as the electroencephalographic (EEG) status of the driver. We have used this system to evaluate practical methods that the driver can utilise to overcome sleepiness (findings from which are incorporated in the Highway Code), and we have shown that dri...
