A process is described for creating a more civerse set of experiences for undergraduate students in mathematics. While we use examples drawn from classes studying linear algebra, the procedures are appropriate for any undergraduate course in mathematics. The diversity of the activities is generated in part through the use of a taxonomy which addresses the nature of the activities rather than a hierarchy of levels of difficulty. All exercises used as illustrations have been attempted by students in second year undergraduate classes. © 1998 Taylor & Francis Group, LLC.

The University of New South Wales (UNSW) high-resolution numerical weather prediction model (HIRES) has been used to forecast wind direction and speed at a height of 10 m over the Sydney to Hobart race yacht area for the past three years. The model is run routinely, three times daily, at the New South Wales Regional Office of the Australian Bureau of Meteorology in Sydney. One of these model runs is out to seven days ahead and its boundary conditions are provided by the Bureau of Meteorology's global model. For the 1996 Sydney to Hobart yacht race the model was run at 25 km resolution out to five days ahead and was subjected to detailed verification by one of the Authors (KLB), who participated in the race aboard the yacht AMP Wild Oats and carried out an observational program during the race. The model winds were verified on a six-hourly basis utilising instrumentation on the yacht. The yacht carried wind sensors, which are situated on top of the yacht's mast at a height of 17.5 m above the water. The authors were interested in both the wind directional trends and the wind speeds forecast by the model. It was found that the model gave overall guidance of good quality but was particularly accurate early in the race when a major wind change known locally as a Southerly Buster occurred just after the start of the race. Later in the race from about the fourth day, the quality of the forecasts decreased in accuracy. An improved version of the model, run at higher resolution (10 km), will be verified again in the next race, in December 1997.

The IC intron, found within the DNA polymerase alpha gene of Toxoplasma gondii, was used to evaluate the genetic relationship among 10 strains of T. gondii. Sequence comparison detected polymorphisms within this 652 bp intron which correlated with murine virulence. The results reported here suggest that T. gondii contains two lineages, corresponding with their virulence, evolving independently following their separation. The extensive homology of the IC sequences within the virulent and avirulent groups affirms the close relationship of the strains within the group, as reflected by the identical nucleotide substitutions and dinucleotide insertions/deletions observed. In addition, the presence of the Nde I restriction enzyme site within the IC intron of avirulent strains allows definition of a T. gondii strain as murine virulent or avirulent without needing to test it in vivo.

The gene encoding the catalytic subunit of the Toxoplasma gondii DNA polymerase α enzyme has been isolated. The coding region is 6487 bp in length, containing three introns, and specifies a protein of 1690 aa. The seven conserved regions which characterize the polα polypeptide, as well as four of the five polα-specific aa domains, were found in the T. gondii gene. The absence of one of these domains, as well as the presence of a unique cysteine cluster between domains IV and B in the T. gondii polα, may result in a slight difference in the secondary or even tertiary structure compared with the human homologue and thus may be suitable for designing anti-Toxoplasma drugs. A number of amino acid differences within the seven conserved regions between the human and T. gondii polα, as well as variations in the spacings of these regions, were also observed.

We develop a family of distributions which allow for over- and underdispersion relative to the Poisson. This latter feature is particularly appealing since many existing methods only allow for overdispersion. These distributions arise from underlying continuous-time Markov processes in which event rates depend on how many events have already occurred. The results are illustrated with underdispersed count data from a polyspermy study and overdispersed data from the Canadian Sickness Survey. (C) 1998 Elsevier Science B.V. All rights reserved.

The phylogenetic relationships and taxonomic affinities of coccidia with isosporan-type oocysts have been unclear as overlapping characters, recently discovered life cycle features, and even recently discovered taxa, continue to be incorporated into biological classifications of the group. We determined the full or partial 18S ribosomal RNA gene sequences of three mammalian Isospora spp., Isospora felix, Isospora ohioensis and Isospora suis, and a Sarcocystis sp. of a rattlesnake, and used these sequences for a phylogenetic analysis of the genus Isospora and the cyst-forming coccidia. Various alveolate 18S rDNA sequences were aligned and analyzed using maximum parsimony to obtain a phylogenetic hypothesis for the group. The three Isospora spp. were found to be most closely related to Toxoplasma gondii and Neospora caninum. This clade in turn formed the sister group to the Sarcocystis spp. included in the analysis. The results confirm that the genus Isospora does not belong to the family Eimeriidae, but should be classified together with the cyst-forming coccidia in the family Sarcocystidae. Furthermore, there appear to be two lineages within the Sarcocystidae. One lineage comprises Isospora and the Toxoplasma/Neospora clade which share the characters of having a proliferative phase of development preceding gamogony in the definitive host and an exogenous phase of sporogony. The other lineage comprises the Sarcocystis spp. which have no proliferative phase in the definitive host and an endogenous phase of sporogony.

Estimating equations have found wide popularity recently in parametric problems, yielding consistent estimators with asymptotically valid inferences obtained via the sandwich formula. Motivated by a problem in nutritional epidemiology, we use estimating equations to derive nonparametric estimators of a “parameter” depending on a predictor. The nonparametric component is estimated via local polynomials with loess or kernel weighting; asymptotic theory is derived for the latter. In keeping with the estimating equation paradigm, variances of the nonparametric function estimate are estimated using the sandwich method, in an automatic fashion, without the need (typical in the literature) to derive asymptotic formulas and plug-in an estimate of a density function. The same philosophy is used in estimating the bias of the nonparametric function; that is, an empirical method is used without deriving asymptotic theory on a case-by-case basis. The methods are applied to a series of examples. The application to nutrition is called “nonparametric calibration” after the term used for studies in that field. Other applications include local polynomial regression for generalized linear models, robust local regression, and local transformations in a latent variable model. Extensions to partially parametric models are discussed. © 1998 Taylor & Francis Group, LLC.

A number of localizations for the putative susceptibility gene(s) have been identified for both Crohn's disease and ulcerative colitis. In a genome wide scan, Hugot et al, (1996) identified a region on chromosome 16 which appeared to be responsible for the inheritance of inflammatory bowel disease in a small proportion of families. Subsequent work has suggested that this localization is important for susceptibility to Crohn's disease rather than ulcerative colitis. We investigated the contribution of this localization to the inheritance of inflammatory bowel disease in 54 multiplex Australian families, and confirmed its importance in a significant proportion of Crohn's disease families; we further refined the localization to a region near to D16S409, obtaining a maximum LOD score of 6.3 between D16S409 and D16S753.

We give an elementary unified approach to rank one symmetric spaces of the noncompact type, including proofs of their basic properties and of their classification, with the development of a formalism to facilitate future computations. Our approach is based on the theory of Lie groups of H-type. An algebraic condition of H-type algebras, called J2, is crucial in the description of the symmetric spaces. The classification of H-type algebras satisfying J2 leads to a very simple description of the rank one symmetric spaces of the noncompact type. We also prove Kostant's double transitive theorem; we describe explicitly the Riemannian metric of the space and the standard decompositions of its isometry group. Examples of the use of our theory include the description of the Poisson kernel and the admissible domains for convergence of Poisson integrals to the boundary. © 1998 The Journal of Geometric Analysis.

The coding regions from five avirulence (avr) genes from Xanthomonas campestris pv. malvacearum (Xcm), the causal agent of bacterial blight of cotton, were joined to the cauliflower mosaic virus 35S promoter and expressed transiently in cotton leaves after Agrobacterium tumefaciens-mediated gene transfer. A genotype-specific necrosis was observed 3 to 6 days post inoculation for constructs derived from avrB4, avrb7, and avrBIn on cotton lines containing the resistance (R) genes B4, b7, and BIn, respectively, but not on susceptible cotton plants. No necrosis was obtained with plasmids that direct expression of avr genes within A. tumefaciens, showing that the cotton response required transfer of the genes into the plant cells. Addition of a signal peptide sequence into the avr constructs to target expressed Avr protein to the apoplast significantly reduced the responses. The results indicate that intracellular expression of Xcm Avr proteins in cotton having the corresponding R gene causes specific host cell death.

View description>>

Control of the transition to flowering is critical for reproductive success of a plant. Studies in Arabidopsis have led us to suggest how this species has harnessed the environmental cue of a period of low temperature to ensure flowering occurs at an appropriate time. We propose that Arabidopsis has both vernalization-independent and vernalization-dependent pathways for the initiation of inflorescence development in the shoot apex. The vernalization-independent pathway may be concerned with the supply of carbohydrate to the shoot apex. In late flowering ecotypes which respond to vernalization the vernalization-independent pathway is blocked by the action of two dominant repressors of flowering, FRI and FLC, which interact to produce very late flowering plants which respond strongly to vernalization. We have isolated a gene which may correspond to FLC. We suggest the vernalization-dependent pathway, which may be concerned with apical GA biosynthesis, is blocked by methylation of a gene critical for flowering. This gene may correspond to that encoding kaurenoic acid hydroxylase (KAH), an enzyme catalysing a step in the GA biosynthetic pathway. Under this scheme vernalization causes unblocking of this pathway by demethylation possibly of the KAH gene and consequent biosynthesis of active GAs in the apex.

View description>>

We have measured the energy-momentum density of amorphous silicon dioxide using an (e,2e) spectrometer with 20.8 keV incident, 19.6 keV scattered, and 1.2-keV ejected electron energies. The amorphous SiO2 sample was prepared by oxidizing a thin silicon membrane. The experimental data show a valence electronic structure characteristic of upper p-like and lower s-like bands. The width of the upper valence band is 10 eV. This is separated by 9 eV from the lower valence band, which exhibits 2-eV dispersion. We have calculated the energy-momentum density of alpha-quartz using the ab initio linear muffin-tin orbital method and the result is spherically averaged over all crystal directions to enable comparison with the experiment. The calculated electron momentum densities show very good agreement with experiment for both the upper and lower valence bands. The theoretical prediction of the energy separation between the upper and lower valence bands is about 2 eV smaller than that measured and this discrepancy is discussed. The agreement between theory and experiment suggests that the short-range order in silicon dioxide plays an important role in determining the electronic structure of this material.

Current models of immunity to blood stages of Plasmodium invoke a primary role for T-cell dependent processes and much recent evidence implicates Th1-type responses as crucial to the control of acute malaria. But do these data stand up to close scrutiny? Here, Andy Fell and Nick Smith review recent data from rodent and human studies and suggest that Th1-type responses may not after all be important in controlling malaria infection in the blood.

We formulate some general network (and risk) management problems in a Bayesian context, and point out some of the essential features. We argue and demonstrate that, when one is interested in rare events, the Bayesian and frequentist approaches can lead to very different strategies: the former typically leads to strategies which are more conservative. We also present an asymptotic formula for the predictive probability of ruin (for a random walk with positive drift) for large initial capital and large number of past observations. This is a preliminary investigation which raises many interesting questions for future research.

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. Protein interaction with each of the test materials caused a net increase in mass of the material indicating protein binding except for lysozyme interacting with P(HEMAMAA). A net decrease in mass was observed for lysozyme interacting with P(HEMAMAA) which may be ascribed to lysozyme collapsing the hydrogel by expelling water. A net mass decrease was observed for cholesterol interacting with each of the hydrogel materials, while a mass increase was observed on PMMA.

View description>>

Safety assessment for noncancer health effects generally has been based upon dividing a no observed adverse effect (NOAEL) by uncertainty (safety) factors to provide an acceptable daily intake (ADI) or reference dose (RfD). Since the NOAEL does not utilize all of the available dose-response data, allows higher ADI from poorer experiments, and may have an unknown, unacceptable level of risk, the benchmark dose (BD) with a specified, controlled low level of risk has become popular as an adjunct to the NOAEL or the low observed adverse effect level (LOAEL) in the safety assessment process. The purpose of this paper is to summarize statistical procedures available for calculating BDs and their confidence limits for noncancer endpoints. Procedures are presented and illustrated for quantal (binary), quasicontinuous (proportion), and continuous data. Quasicontinuous data arise in developmental studies where the measure of an effect for a fetus is quantal (normal or abnormal) but the experimental unit is the mother (litter) so that results can be expressed as the proportion of abnormal fetuses per litter. However, the correlation of effects among fetuses within a litter poses some additional statistical problems. Also, developmental studies usually include some continuous measures, such as fetal body weight or length. With continuous data there generally is not a clear demarcation between normal and adverse measurements. In such cases, extremely high and/or low measurements at some designated percentile(s) can be considered abnormal. Then the probability (risk) of abnormal individuals can be estimated as a function of dose. The procedure for estimating a ED with continuous data is illustrated using neurotoxicity data. When multiple measures of adverse effects are available, a BD can be estimated based on a selected endpoint or the appearance of any combination of endpoints. Multivariate procedures are illustrated using developmental and reproductive toxicity data.

Many bacteria produce reddish brown to black pigments and some of these have been characterised. This report describes the isolation and characterisation of a diffusible brown melanin-like pigment from the bacterium Aeromonas media. Physico-chemical testing suggested that the pigment is a true melanin. New butanol-soluble yellow, red and brown pigments were isolated from the A. media strain under reducing conditions during melanogenesis and these pigments were shown to be unstable precursors of the polymeric brown melanin product.

Home training in self-lowering of blood pressure using continuous blood pressure feedback has not previously been reported. Enhancement of laboratory-learned skills was hypothesized on the basis of outcomes from other intellectual, emotional and physical endeavours. To examine the supplementary effect of home blood pressure biofeedback training. Thirty unmedicated, mild hypertensives participated in a randomized, double-blinded, modified contingency placebo-controlled study. After suitable screening and baseline blood pressure measurements subjects undertook eight laboratory biofeedback sessions and then 12 home training sessions over 4 weeks using continuous finger blood pressure monitoring. In the laboratory those being administered active therapy (n = 16) lowered systolic pressures by 5 +/- 5.4 mmHg compared with a lowering of 4 +/- 4.2 mmHg with placebo (NS), During the fourth week at home lowering for the active group (11 +/- 8 mmHg) was greater than that with placebo (4 +/- 6.2 mmHg, P = 0.017), Arm-cuff blood pressures were not statistically different for groups and with time but that of the active group was lower by 9 +/- 15.4/7 +/- 0.2 mmHg, which is a clinically relevant change, after home biofeedback. The efficacy of self-lowering of systolic blood pressure in mild hypertensives by continuous feedback was enhanced by 6 mmHg with 4 weeks of practice at home. Standard arm-cuff blood pressure was reduced by a clinically relevant amount The home environment proved cost effective for this 'high-tech' approach.

View description>>

When aqueous solutions containing Fe2+ ions are irradiated at <250 nm, photooxidation to Fe3+occurs and molecular hydrogen is generated. This plwtoprocess has been studied extensively for over 60 years, but without agreement being reached about the nature of the primary step. Possible initial steps include metal-to-ligand charge transfer (MLCT), internal Fe2+ 3d4s absorption, direct electron photodetachment producing a partially solvated electron in a pre-existing solvent cavity, and polaron-type charge transfer to solvent (CTTS) absorption. We consider the energetics and solvent shift of the first three of these processes, concluding that the MLCT band is too high in energy, the 3d -4s excitation could participate, and the direct photodetachment band is at the correct energy and intensity to account for all that is (as yet) observed of the absorption band. In general, a rather complicated picture of this process in inorganic complexes emerges. In this work, we apply a general method tue have developed for estimating the effects of solvents on transitions of species that have strong specific interactions (e.g., hydrogen bonding) with the solvent molecules. © 1998 American Chemical Society.

Historical data often play an important role in helping interpret the results of a current study. This article is motivated primarily by one specific application: the analysis of data from rodent carcinogenicity studies. By proposing a suitable informative prior distribution on the relationship between control outcome data and covariates, we derive modified trend test statistics that incorporate historical control information to adjust for covariate effects. Frequentist and fully Bayesian methods are presented, and novel computational techniques are developed to compute the test statistics. Several attractive theoretical and computational properties of the proposed priors are derived. In addition, a semiautomatic elicitation scheme for the priors is developed. Our approach is used to modify a widely used prevalence test for carcinogenicity studies. The proposed methodology is applied to data from a National Toxicology Program carcinogenicity experiment and is shown to provide helpful insight on the results of the analysis.

A complete life cycle for the ubiquitous protozoan parasite Toxoplasma was proposed over 25 years ago. Since that time, despite attempts to make the genus polyspecific, there has been only one species, Toxoplasma gondii, consistently recognised in the genus. Recent studies on taxa in genera closely related to Toxoplasma such as Neospora, Hammondia, Frenkelia, Isospora and Sarcocystis, have convincingly showed the need for a reclassification of many of the species in these genera. However, in addition to these genus level studies, over the last 10 years several laboratories have used molecular techniques including isoenzyme electrophoresis, restriction fragment length polymorphism analyses, random amplified polymorphic DNA - polymerase chain reaction, and comparisons of the small subunit ribosomal RNA gene, DNA polymerase alpha intron, and 70 kDa heat shock protein gene nucleotide sequences to investigate the genetic diversity among strains in the species T. gondii. Overall, the results of these analyses confirm that the strains in the genus Toxoplasma comprise a limited number of clonal lineages, directly correlated with their virulence in mice. The aim of this presentation is to review the molecular research in this area in order to raise the hypothesis that there may be more than one species in the genus Toxoplasma, which may contain taxa with distinct and different life cycles.

View description>>

Multidrug resistance to anti-cancer drugs is a major medical problem. Resistance is manifested largely by the product of the human MDR1 gene, P-glycoprotein, an ABC transporter that is an integral membrane protein of 1280 amino acids arranged into two homologous halves, each comprising 6 putative transmembrane ?-helices and an ATP binding domain. Despite the plethora of data from site-directed, scanning and domain replacement mutagenesis, epitope mapping and photoaffinity labeling, a clear structural model for P-glycoprotein remains largely elusive. In this report, we propose a new model for P-glycoprotein that is supported by the vast body of previous data. The model comprises 2 membrane-embedded 16-strand ?-barrels, attached by short loops to two 6-helix bundles beneath each barrel. Each ATP binding domain contributes 2 ?-strands and 1 ?-helix to the structure. This model, together with an analysis of the amino acid sequence alignment of P-glycoprotein isoforms, is used to delineate drug binding and translocation sites. We show that the locations of these sites are consistent with mutational, kinetic and labeling data.

The early effects of heat stress on the photosynthesis of symbiotic dinoflagellates (zooxanthellae) within the tissues of a reef-building coral were examined using pulse-amplitude-modulated (PAM) chlorophyll fluorescence and photorespirometry. Exposure of Stylophora pistillata to 33 and 34 °C for 4 h resulted in (1) the development of strong non-photochemical quenching (qN) of the chlorophyll fluorescence signal, (2) marked decreases in photosynthetic oxygen evolution, and (3) decreases in optimal quantum yield (F(v)/F(m)) of photosystem II (PSII). Quantum yield decreased to a greater extent on the illuminated surfaces of coral branches than on lower (shaded) surfaces, and also when high irradiance intensities were combined with elevated temperature (33 °C as opposed to 28 °C). qN collapsed in heat-stressed samples when quenching analysis was conducted in the absence of oxygen. Collectively, these observations are interpreted as the initiation of photoprotective dissipation of excess absorbed energy as heat (qN) and O2-dependent electron flow through the Mehler-Ascorbate-Peroxidase cycle (MAP-cycle) following the point at which the rate of light-driven electron transport exceeds the capacity of the Calvin cycle. A model for coral bleaching is proposed whereby the primary site of heat damage in S. pistillata is carboxylation within the Calvin cycle, as has been observed during heat damage in higher plants. Damage to PSII and a reduction in F(v)/F(m) (i.e. photoinhibition) are secondary effects following the overwhelming of photoprotective mechanisms by light. This secondary factor increases the effect of the primary variable, temperature. Potential restrictions of electron flow in heat-stressed zooxanthellae are discussed with respect to Calvin cycle enzymes and the unusual status of the dinoflagellate Rubisco. Significant features of our model are that (1) damage to PSII is not the initial step in the sequence of heat stress in zooxanthellae, and (2) light plays ...

The first Moderate Resolution Imaging Spectroradiometer (MODIS) instrument is planned for launch by NASA in 1998. This instrument will provide a new and improved capability for terrestrial satellite remote sensing aimed at meeting the needs of global change research. The MODIS standard products will provide new and improved tools for moderate resolution land surface monitoring. These higher order data products have been designed to remove the burden of certain common types of data processing from the user community and meet the more general needs of global-to-regional monitoring, modeling, and assessment. The near-daily coverage of moderate resolution data from MODIS, coupled with the planned increase in high-resolution sampling from Landsat 7, will provide a powerful combination of observations. The full potential of MODIS will be realized once a stable and well-calibrated time-series of multispectral data has been established. In this paper the proposed MODIS standard products for land applications are described along with the current plans for data quality assessment and product validation

Traditionally, mental health professionals and school authorities have found school refusal to be a perplexing and challenging problem. Relevant to an understanding of school refusal, we initially review some important developmental-normative considerations. The clinical features, epidemiology, and etiology of school refusal are also briefly discussed. We then describe a number of behavioural strategies that have been used in the management of school refusal. Finally, we review the research support for the efficacy and acceptability of behavioural strategies in the treatment of school refusal.

For the protection of clients and the long-term survival of their profession, clinical psychologists are being urged to take a leading role in the promotion of empirically validated treatments. Recently, the American Psychological Association's Division of Clinical Psychology (Division 12) established a Task Force on Promotion and Dissemination of Psychological Procedures to define empirically validated treatment and make recommendations in relation to methods for educating mental health professionals, third party payers and the public about effective psychotherapies. Predictably, the task force report has a somewhat controversial status but continues to be an influential "blueprint" for the improvement of clinical psychology in various countries including Australia.

Childhood phobias are complexly determined but responsive to behavioral interventions. This review focuses on emotive imagery, a variant of systematic desensitization developed specifically for use in treatment of children's excessive fears. Although emotive imagery appears to be a useful treatment procedure, further research is needed before it could be considered as having 'well-established' empirical status. Several other important methodological and theoretical issues are emphasized.

Background. School-based relaxation training programmes are a popular means of helping children with anxiety problems such as headaches and test anxiety. Aims. Our major objective is to evaluate the empirical status of school-based relaxation training programmes. Contents. Focusing on progressive muscle relaxation training, we show how this adult training procedure has been modified for use with children. Several training issues are discussed including the questions of live versus recorded instruction and individual versus group instruction. We also discuss the evaluation of relaxation training programmes in school settings, highlighting issues of reliability and validity. Conclusions. Our review of studies examining the efficacy of school-based relaxation training shows that improvements are usually modest and of dubious clinical or educational significance. Consequently we suggest that when relaxation training is used with school children treatment goals should be more modest or, that if improvements in specific performance areas are sought, then more comprehensive treatment packages be developed which can influence the successful performance of children in target areas and reduce anxiety to normal levels.

Objective: To evaluate the efficacy of a 4-week cognitive-behavioral treatment program for children who refuse to go to school. Method: Thirty- four school-refusing children (aged 5 to 15 years) were randomly assigned to a cognitive-behavioral treatment condition or a waiting-list control condition. Treatment consisted of individual child cognitive-behavioral therapy plus parent/teacher training in child behavior management skills. Measures taken before and after treatment included school attendance, child self-report of emotional distress and coping, caregiver reports on emotional and behavioral problems, and clinician ratings of global functioning. Results: Relative to waiting-list controls, children who received cognitive- behavioral therapy exhibited a significant improvement in school attendance. These children also improved on self-reports of fear, anxiety, depression, and coping. Significant improvements also occurred in relation to caregiver reports and clinician ratings. Maintenance of therapeutic gains was demonstrated at a 3-month follow-up assessment. Conclusions: Cognitive- behavioral treatment of school refusal was efficacious and acceptable. The relative contributions of child therapy and parent/teacher training require further study.

Sintering in air and hot isostatic pressing are production methods regarded as being capable of producing fibre-reinforced hydroxyapatite ceramics for biomedical applications. These composites may have the advantage of improved mechanical properties and be suitable for applications in areas where there are significant levels of load on the material. The use of pure hydroxyapatite is restricted to those free of dynamical load. Obtaining improved mechanical strength is a question of the bond between the matrix phase and the fibre-reinforcement phase. However, a chemical bond between both phases, indicated by large diffusion zones, might lead to the dehydration of the hydroxyapatite leading to undesired tricalcium phosphate in the matrix resulting in a weakening of the mechanical and biological stability of the composites. Composites with three fibre types, alumina, 316L-stainless steel and titanium were prepared and sintered in air or hot isostatically pressed. A reaction zone was noted around the titanium and stainless steel fibres, but not around the alumina fibres. The reaction zone was larger for stainless steel than titanium. Hot isostatic pressing also reduced the reaction zone markedly compared to sintering in air.

This work introduces electronic network modeling as a new way of simulating battery behavior. Mathematical descriptions are given for the Ni and Cd electrode charge/discharge reactions These mathematical descriptions are subsequently introduced in the form of electronic components, combined in an electronic network The advantage of this way of modeling is that it provides a compact electronic model of a battery, which can be used in any electronic-circuit simulation, providing a tool to develop new battery-management systems In addition, due to the discretization of the electrochemical reactions into separate electronic components, local currents and overpotentials occurring in the system can be studied. This information can be used to investigate the origin of certain battery behavior.

Smoke pollution from controlled burning of forested areas can be a major problem for populated areas, even those at some distance from the site of the burning. In particular, Perth, the largest city in Western Australia, is affected by smoke from controlled forest burns to the south of the city when meteorological conditions advect smoke over the city. Such controlled burns are extensively carried out on an annual basis in spring, early summer and late autumn by the Western Australian Department of Conservation and Land Management (CALM) in the southwest forests, in order to reduce flammable fuels and mitigate the undesirable social, economic, environmental and human problems caused by destructive wildfires. In this article, results are presented from a mesoscale model prediction of smoke trajectories from a controlled burn event that took place in November, 1995. In this example, two meteorological factors, a strong sea-breeze front and a mesoscale low pressure system, unexpectedly turned the smoke back from its initial trajectory over the ocean to directly over Perth itself. The result was very high smoke concentration levels over the city and associated health concerns to residents as well as disruption to transport including the closing of Perth airport. The mesoscale guidance was very accurate and can provide valuable guidance when run routinely.

In standard time-to-event or survival analysis, occurrence times of the event of interest are observed exactly or are right-censored, meaning that it is only known that the event occurred after the last observation time, There are numerous methods available for estimating the survival curve and for testing and estimation of the effects of covariates in this context. In some situations, however, the times of the events of interest may only be known to have occurred within an interval of time. In clinical trials, for example, patients are often seen at pre-scheduled visits but the event of interest may occur in between visits. These data are interval-censored. Owing to the lack of well-known statistical methodology and available software, a common ad hoc approach is to assume that the event occurred at the end (or beginning or midpoint) of each interval, and then apply methods for standard time-to-event data. However, this approach can lead to invalid inferences, and in particular will tend to underestimate the standard errors of the estimated parameters. The purpose of this tutorial is to illustrate and compare available methods which correctly treat the data as being interval-censored. It is not meant to be a full review of all existing methods, but only those which are available in standard statistical software, or which can be easily programmed. All approaches will be illustrated on two data sets and compared with methods which ignore the interval-censored nature of the data. We hope this tutorial will allow those familiar with the application of standard survival analysis techniques the option of applying appropriate methods when presented with interval-censored data.

Abstract. Radiomelrtcally calibrated, Airborne Visible Infrared Imaging SpectromeIer (AVIRIS) images acquired during the Smoke, Clouds and Radiation in Brazil (SCAR-B) experiment were processed to simulate vegetation index (VI) imagery with the Moderate Resolution Imaging SpectroradiomeIer (MODIS) band passes. Data sets were extracted from tropical forested areas, burned fields, and shrub/grassland areas over both clear and variable smoke conditions wIth average aerosol optical thickness (AOT) values at 0.67 flm of 0.14, 1.1, and 1.9, respectively. The atmospheric resistant VIs and various middle-infrared (MlR) derived Vis were then analyzed with respect to their ability 10 minimize atmospheric "smoke" contamination. The atmospheric resistant VIs utilized the blue band for correction of !he red band, while !he MlR-derived Vis used !he MIR region (1.3 - 2.5 flm) as a substitute for the red band since it is relatively transparent to smoke, yet remains sensitive to green vegetation. The performance of lhese indices were assessed and compared wi!h !he normalized difference vegetation index (NDVI) and !he soil-adjusIed vegetation index (SAVI). Over !he tropical forests !he NDVI and SAVI had high relative errors over all smoke-filled atmospheric conditions (50-80% error), while !he atmospheric resistant VIs resulted in a 50-80% relative error only over thick levels of smoke.

The Australian continent provides an important test of macroecological patterns given its unique biota and long-term geographical isolation. However, macro- ecological contributions from the Australian continent are rare. We explored the relationship between abundance and geographical range for Australian frogs (Order Anura) across complete geographical ranges, and investigated how adult body size relates to both abundance and the size of geographical ranges.

The complexes trans-[Ru(2-C≡CC5H3N-5-R)Cl(dppm)2] [R = H (6), NO2 (7)] have been prepared and 7 has been structurally characterized; comparison with the structural study of trans-[Ru(4-C≡CC6H4NO2)Cl(dppm) 2] (3) reveals a decrease in Ru-C(1) distance and increase in Ru-Cl(1) distance, consistent with stronger σ-bonding by the nitropyridylalkynyl ligand in 7 compared to the nitrophenylalkynyl ligand in 3. Electrochemical data for 3, 6, 7, precursor dichloro complexes [RuCl2(dppm)2] [cis (1a), trans (1b)], and related alkynyl complexes trans-[Ru(4-C≡CC6H4R)Cl(dppm)2] [R = H (2), 4-C6H4NO2 (4), (E)-4-CH=CHC6H4NO2 (5)] have been determined by cyclic voltammetry. Introduction of nitro substituent in progressing from 2 to 3 or 6 to 7 leads to a substantial increase in EoRuII/III, most of which is lost on chain-lengthening the alkynyl ligand in progressing from 3 to 4 or 5. Replacement of phenyl by pyridyl in progressing from 2 to 6 or 3 to 7 results in a 0.1 V increase in EoRuII/III. The optical spectra of representative complexes have been examined. Introduction of a nitro substituent onto the phenylalkynyl ligand, in progressing from 2 to 3, results in a substantial (ca. 11000 cm-1) red-shift in the intense MLCT band of the RuII-C≡C-Ar-NO2 moiety. Complexes 3, 4 and 5 exhibit sizable solvatochromic shifts, suggestive of significant optical nonlinearities. Quadratic hyperpolarizabilities for 2-7 were determined by hyper-Rayleigh scattering (HRS) at 1064 nm; measurements are consistent with an increase in βHRS upon incorporation of nitro substituent (progressing from 2 to 3 or 6 to 7), chain-lengthening the alkynyl ligand (progressing from 3 to 4 and then to 5) and replacing phenyl by pyridyl in progressing from 2 to 6, general trends that are maintained with the two-level-corrected data, and which parallel shifts in λmax to low energy. The observed and two-level-corrected βHRS values for 7 are lower than expected; it is perhaps significant that λmax for 7 is close to ...

Based on the concept of a defined sealed rechargeable NiCd battery, the mathematics of the various electrochemical and physical processes occurring inside the battery are described. Subsequently, these sets of mathematical equations are clustered and converted into an electronic network model. Introducing the relevant electrochemical and physical parameters, the one-dimensional model is shown to be capable of simulating not only the development of the cell voltage during (over)charging and (over)discharging. but also of simultaneously calculating the development of the internal gas pressure. Considering the thermal dependencies of the various electrochemical reactions and those of the battery environment, the temperature development and the mutual interaction with the voltage and gas pressure can also be calculated. Since the electronic network approach gives access to all partial currents flowing through the different reaction paths inside the battery, it is easy to visualize what processes are occurring during battery operation This is. for example, illustrated for the two-step overdischarge process, indicating that, respectively, the Cd and O2 charge-transfer reactions play a dominant role under these conditions. Electronic network simulations are shown to be not only restricted to direct current applications but are also applicable to processes, like open-circuit voltage relaxation and self-discharge behavior.

We consider a model of a complete market with two assets under the suggestion that an investor may hedge the payoff function with the given probability; in othei words, the investor should have capital not less than the given payoff function with probability not less than 1 - α (α is a given significance level). Under some limitations on a class of hedging strategies we find a lower bound for an option price (that it, for the initial capital of the investor) and construct a hedge (the investor strategy) for which this lower bound is achieved. For examples, we calculate the price and hedge of a European call option and also an American call option with a barrier condition.

Random amplified polymorphic DNA polymerase chain reaction (RAPD-PCR) uses arbitrary primers and low stringency annealing conditions to amplify anonymous DNA fragments which are then depicted in agarose gels. RAPD-PCR fingerprints have been used for typing and differentiation of bacteria and, increasingly, for the study of genetic relationships between strains and species of microorganisms, plants and animals. The analysis of such fingerprints is based upon the assumption that comigration of amplicons does not occur and that any given band contains a single amplicon. This report shows that comigration of fragments of nearly identical size, but different nucleotide sequences, occurs between different isolates and within single RAPD-PCR bands from Aeromonas hydrophila. The possibility of the same phenomenon occurring for other prokaryotic or eukaryotic genomes argues for caution in the interpretation of RAPD-PCR fingerprints.

Reviewed panic attacks and panic disorders in children and adolescents critically and highlighted new developments. It is concluded that panic attacks and panic disorder are common in adolescence and that they are responsive to cognitive-behavioral treatment regimens. It is also concluded that although panic attacks and panic disorder are less common in children, they are nonetheless present. It is important to note, however, that their expression in childhood may vary from the clinical features seen in adolescence and adulthood. Specifically, it is suggested that most panic attacks in childhood are associated with particular events and are not unexpected or "out of the blue." Moreover, noncatastrophic interpretations of the symptoms of panic prevail. A developmental model for the onset, course, and correlates of panic in children is put forth.

School refusal is a complex and heterogeneously determined and experienced behaviour problem. Due to its complexity and heterogeneity, a multimethod and multisource approach to assessment is required. The approach is described as a hypothesis-testing approach which uses developmentally sensitive and empirically validated procedures. Clinical-behavioural interviews, structured diagnostic interviews, self-reports, reports of significant others, self-monitoring, and behavioural observations are recommended. Issues associated with these procedures are reviewed.

Reviews the empirically supported status of behavioral and cognitive-behavioral interventions in the treatment of childhood phobias and anxiety disorders. For childhood phobias, it is concluded that imaginal desensitization, in vivo desensitization, filmed modeling, live modeling, and cognitive-behavioral interventions that use self-instruction training are probably efficacious and that participant modeling and reinforced practice are well established. For anxiety disorders, only cognitive-behavioral procedures with and without family anxiety management (FAM) were found to be probably efficacious. However, much of the support for these procedures comes from analogue studies conducted in research laboratory or school settings, delivered in small-group format and, not infrequently, with nonclinically referred children. Additional research that examines high-strength interventions with clinic-referred children is recommended. Furthermore, research that examines the pathological processes involved in the onset and maintenance of phobic and anxiety disorders as well as the change processes used to treat these disorders is called for.

A method based on a self-organisational approach has been developed, where a local state operator defines the state of each finite element at each iteration. The algorithm is based on the principle of local adaptation with global feedback in the form of a derivative equation based on von Mises stresses that allows the local remodelling function to vary at each time step. The state operator has the form of a nonlinear differential equation solved iteratively based on the material density and strain energy density within each element. A constraint equation is formulated based on a maximum deviatoric strain energy criteria, with the objective to minimise the mass of the design domain subject to the above constraint. A number of examples are presented to demonstrate the use of this approach. © 1997 Elsevier Science Ltd.

A method for the Bayesian restoration of noisy binary images portraying an object with constant grey level on a background is presented. The restoration, performed by fitting a polygon with any number of sides to the object's outline, is driven by a new probabilistic model for the generation of polygons in a compact subset of R2, which is used as a prior distribution for the polygon. Some measurability issues raised by the correct specification of the model are addressed. The simulation from the prior and the calculation of the a posteriori mean of grey levels are carried out through reversible jump Markov chain Monte Carlo computation, whose implementation and convergence properties are also discussed. One example of restoration of a synthetic image is presented and compared with existing pixel-based methods. © 1998 Royal Statistical Society.

Uptake of the toxic heavy-metal, thallium, was studied in the cyanobacterium Synechococcus R-2 (PCC 7942) using clinically available 201Tl+. Thallium was found to distribute across the plasmalemma passively, and so the accumulation ratio of the ion ([TI+]i/[Tl+]o) could be used to calculate the apparent membrane potential (Δψi,o) of the cells (ETli,o+=Δψi,o). The permeability of the plasmalemma to Tl+ (PTl+≈1 to 5 nm s-1) is higher than that of K+. Valinomycin does not increase the permeability of Tl+. Transient changes in the Δψi,o of cells, because of electrogenic transport of ions, could be detected from its effects upon the uptake rate of Tl+. HCO3- hyperpolarized Synechococcus cells, whereas NH4+, CH3NH3+, and K+ led to depolarization. The use of Tl+ as a reporter of Δψi,o has some inherent limitations. Tl+ is toxic at very low concentrations (inhibitory effects are apparent after about 6 h at concentrations as low as 1 mmol m-3). The rate of equilibration is slow (t1/2≈5 to 20 min). Equilibration of Tl+ takes about 2 h, which limits its value as a membrane potential probe. Large amounts of Tl+ bind to the surface of the cells making the method impracticable for measuring accumulation ratios of less than about 10 (Δψi,o values smaller than about -60 mV). Cultures continuously exposed to Tl+ (10 mmol m-3) eventually become Tl+ resistant by actively extruding Tl+ (ΔμTli,o+=-3±0.2 kJ mol-1) and so thallium cannot be used as a Δψi,o probe in such cells.

Cover of and the number of species in encrusting macrobenthic assemblages inhabiting temperate rocky reefs in the vicinity of an ocean outfall changed rapidly following the discharge of secondary treated sewage effluent. Within 3 mo of the commissioning of the outfall, significant reductions in the cover of crustose and foliose algae were apparent when this outfall area was compared to 2 reference locations. The cover of several species of sponge, including Cymbastela concentrica, Geodinella sp. and Spongia sp., also underwent marked declines coincident with the commissioning of the outfall. Only 1 category of cover increased significantly at the outfall; this was a nondescript matrix comprising silt and microorganisms, which doubled its representation to almost 60%. We did not detect significant declines in the cover and number of species of sponges or total fauna, however. A 'Beyond BACI' experimental design was used to determine the environmental impact because of the great spatial and temporal variability in these shallow water (~20 m) encrusting communities. Photographic samples were taken in 3 periods, the first pre-commissioning and the other 2 post-commissioning. Multivariate analyses revealed marked shifts in the structure of the assemblage at the outfall relative to the reference locations; these shifts were clearly depicted by a non-metric multi-dimensional scaling (nMDS) plot. A SIMPER analysis confirmed that the overall composition of the community at the outfall changed from one in which algae and sponges were well represented to an assemblage dominated by silt and ascidians.

View description>>

Rupture of the fibrous cap of an atherosclerotic plaque may result in thrombosis and rapid occlusion of the artery. Since the most vulnerable areas of the plaque contain a large number of macrophages, it is thought that the release of matrix-degrading proteinases by these cells may contribute to the weakening and subsequent rupture of the fibrous cap. While a great deal of research has focused on matrix metalloproteinases, cysteine proteinases can also be secreted by activated macrophages. Cathepsin S is unique among the cysteine proteinases in that it is stable at neutral pH. Increased synthesis of cysteine proteinases may result in their secretion from the cell in the pro-form which, unlike the fully processed protein, is stable at neutral pH values. In this study, human atherosclerotic plaques obtained from carotid endarterectomy were dissected into defined regions. Cysteine proteinase levels in each region were assessed using peptide substrates, western blotting and zyrnography. Localisation of these proteinases was then examined histologically. Increased levels of cathepsins B, L and S were found in extracts of the shoulder region (up to 5 fold higher than normal arterial tissue) and close to the lipid core (up to 10 fold higher than normal arterial tissue). Histochemistry using an active site-directed probe revealed that the active proteinases were located in specific sites within these regions. These proteinases are highly active against many matrix molecules, and thus may produce focal weakening of the fibrous cap. Experiments are currently underway in which activated macrophages are incubated with plaque tissue and the effects of a range of proteinase inhibitors on the cleavage of specific matrix molecules examined.

The C-band ERS-1 SAR data were combined with the Landsat TM data to improve the soil moisture estimates in a semiarid region. The SAR data were compared with the soil moisture measurements at three conditions: a) without any correction for soil roughness and vegetation effects; b) corrected for soil roughness effects; and c) corrected for both soil roughness and vegetation effects. The soil roughness effects were taken into account by using a dry season SAR image. The vegetation influence was considered by using an empirical relationship between SAR and leaf area index data, the latter being derived from TM images. Results indicated that the contribution of soil roughness and vegetation in the radar backscatter were significant and they must be taken into account to obtain accurate soil moisture estimations.

A sensitivity analysis of C-band (5.3 GHz) and Ku-band (14.85 GHz) synthetic aperture radar (SAR) data to the bare soil moisture content of agricultural fields was conducted in this study. The C-band data were obtained with a 23° incidence angle, whereas the Ku-band data were obtained with 35°, 55°, and 75° incidence angles. The fields presented either a small-scale or an intermediate-scale periodic soil roughness components, associated with level-basin and furrow irrigation systems, respectively. For fields with a small-scale roughness component, the SAR data were sensitive to soil moisture, particularly at the C-band with a 23° incidence angle and Ku-band with a 35° incidence angle. For fields with a intermediate-scale roughness component, both C- and Ku-band data were nearly insensitive to soil moisture. By using a theoretical surface scattering model, this study also analyzed the effects of different soil roughness components [root mean square (RMS) height h, correlation length, and periodic row structure] in the SAR data. For fields with RMS height <0.3 cm, a small variation in h (from 0.1 to 0.3 cm) provoked a significant variation in the SAR data (up to 8 dB).

Much evidence exists documenting the comorbidity of anxiety and affective disorders in youth. Furthermore, comorbidity appears to have serious implications both in terms of severity of impairment and course of disorder. Despite this, little is known about the meaning behind the high rate of co-occurrence of anxiety and depression in children and adolescents. Several conditions exist that may give rise to comorbidity. Specifically, two disorders may be comorbid when there is a high rate of symptom overlap between the disorders, when one underlying construct is split into two separate disorders, when the disorders share common risk or etiological factors, or because one disorder causes or increases the risk of developing the second disorder. The present paper examines each of these explanations as they relate to the comorbidity of anxiety and depression in youth. © 1998 Plenum Publishing Corporation.

Predicting rainfall along the New South Wales (NSW) coast is a major forecasting problem because of sharp gradients in rainfall amounts with the heaviest falls on the coastal fringe decreasing rapidly inland. On some occasions the rainfall pattern is less spatially coherent and consists of isolated maxima. Both rainfall patterns are associated with mesoscale coastal ridging. The first rainfall pattern arises from coastal ridging occurring in combination with an offshore trough. In the first case study presented here, a typical ridge-trough system was aligned parallel to the coast, and located just offshore, with the observed rainfall heaviest at the coast, decreasing rapidly from over 60 mm to near zero 30 km inland. The model captured well the southward temporal evolution of the maximum relative humidity values and rainfall. The second rainfall pattern occurs when shallow coastal ridging interacts with downdrafts from thunderstorm activity over the ranges to the west. The second case study was one in which convergence and condensation generated a quasi-stationary line of thunderstorms, resulting in flash flooding. The model precipitation rates and accumulations matched very closely those of the squall line, as revealed by radar precipitation intensities and the observed rainfall.

Objective: To examine the efficacy of a combination of 4 blood markers of alcohol use in detecting alcohol-abusing pregnant women. Study design: Two new markers of alcohol use, whole blood-associated acetaldehyde and carbohydrate-deficient transferrin, and 2 traditional markers of alcohol use, gamma-glutamyl transpeptidase and mean red blood cell volume, were measured in the blood of pregnant women. Each woman was interviewed about alcohol and drug use, medical and obstetric histories, and nutrition. Each infant was examined by a clinician who was blinded to exposure status. Results: All of the women who reported drinking an average of 1 or more ounces of absolute alcohol per day had at least, 1 positive blood marker. The infants of mothers with 2 or more positive markers had significantly smaller birth weights, lengths, and head circumferences than the infants with negative maternal screens. The presence of 2 or more positive markers was more predictive of infant outcome than any self-reporting measure. Conclusions: These markers, which detect more at-risk pregnant women than self-reporting methods, could lead to better efforts at detection and prevention of alcohol-induced fetal damage.

Carney complex (CC), Pentz-Jeghers syndrome (PJS), Cowden disease (CD), and Bannayan-Zonana syndrome (BZS) share clinical features, such as mucocutaneous lentigines and multiple tumors (thyroid, breast, ovarian, and testicular neoplasms), and autosomal dominant inheritance. A genetic locus has been identified for CC on chromosome 2 (2p16), and the genes for PJS, CD, and BZS were recently identified; genetic heterogeneity appears likely in both CC and PJS. The genes for PJS and CD/BZS, STK11/LKB1 and PTEN, respectively, may act as tumor suppressors, because loss of heterozygosity (LOH) of the PJS and CD/BZS loci has been demonstrated in tumors excised from patients with these disorders. We studied 2 families with CC in whom the disease could not be shown to segregate with polymorphic markers from the 2p16 locus. Their members presented with lesions frequently seen in PJS and the other lentiginosis syndromes. We also tested 16 tumors and cell lines established from patients with CC for LOH involving the PJS and CD/BZS loci. DNA was extracted from peripheral blood, tumor cell lines, and tissues and subjected to PCR amplification with primers from microsatellite sequences flanking the STK11/LKB1 and PTEN genes on 19p13 and 10q23, respectively, and a putative PJS locus on 19q13. All loci were excluded as candidates in both families with LOD scores less than -2 and/or by haplotype analysis. LOH for these loci was not present in any of the tumors that were histologically identical to those seen in PJS. The overall rate of LOH for the PJS and CD/BZS loci in tumors from patients with CC was less than 10%. We conclude that despite substantial clinical overlap among CC, PJS, CD, and BZS, LOH for the STK11 and PTEN loci is an infrequent event in CC-related tumors. Linkage analysis excluded the PJS and CD/BZS loci on chromosomes 19 (19p13 and 19q13) and 10 (10q23) from harboring the gene defect(s) responsible for the phenotype in these 2 families.

View description>>

We consider generalized linear mixed models (GLMMs) for clustered data when one of the predictors is measured with error. When the measurement error is additive and normally distributed and the error-prone predictor is itself normally distributed, we show that the observed data also follow a GLMM but with a different fixed effects structure from the original model, a different and more complex random effects structure, and restrictions on the parameters. This characterization enables us to compute the biases that result in common GLMMs when one ignores measurement error. For instance, in one common situation the biases in parameter estimates become larger as the number of observations within a cluster increases, both for regression coefficients and for variance components. Parameter estimation is described using the SIMEX method, a relatively new functional method that makes no assumptions about the structure of the unobservable predictors. Simulations and an example illustrate the results. © 1998 Taylor & Francis Group, LLC.

View description>>

Studies of reptilian thermoregulation have tended to focus on diurnal heliothermic taxa that display overt thermoregulatory behavior, with nocturnal reptiles attracting less attention. We studied thermoregulation by the broad-headed snake (Hoplocephalus bungaroides), a small (mean snout-vent length = 57 cm) nocturnal elapid that spends long periods sequestered in diurnal retreat sites. The snakes selected body temperatures of 28.1 degrees-31.1 degrees C in laboratory thermal gradients. Prey-capture ability (strike speed and accuracy) increased at higher body temperatures over the range 20 degrees-30 degrees C. Using temperature-sensitive radio transmitters, we obtained 7,801 body-temperature measurements of 19 free-ranging snakes. Information on operative environmental temperatures was obtained at the same time. From these data, we quantified the degree to which the snakes exploit the environmental thermal heterogeneity available to them (i.e., the time they spent within their setpoint range, relative to the total time that these body temperatures were available to them). Mean body temperatures (both diurnally and nocturnally) differed among seasons but not among different types of retreat sites. Inclement weather prevented snakes from attaining "preferred" body temperatures on 30% of days. However, even when preferred temperatures were available, the snakes exploited this opportunity for only 26% of the time: they remained within retreat sites and rarely emerged to bask. Nonetheless, judicious retreat-site selection resulted in snakes being within their set-point range for 60% of the time at the most crucial time of day (i.e., the 2-h period around dusk, when the opportunity to capture prey is highest).

Among the tests that can be used to detect dose-related trends in count data from toxicological studies are nonparametric tests such as the Jonckheere-Terpstra and likelihood-based tests, for example, based on a Poisson model. This paper was motivated by a data set of tumor counts in which conflicting conclusions were obtained using these two tests. To define situations where one test may be preferable, we compared the small and large sample performance of these two tests as well as a robust and conditional version of the likelihood-based test in the absence and presence of a dose-related trend for both Poisson and overdispersed Poisson data. Based on our results, we suggest using the Poisson test when little overdispersion is present in the data. For more overdispersed data, we recommend using the robust Poisson test for highly discrete data (response rate lower than 2-3) and the robust Poisson test or the Jonckheere-Terpstra test for moderately discrete or continuous data (average responses larger than 2 or 3). We also studied the effects of dose metameter misspecification. A clear effect on efficiency was seen when the 'wrong' dose metameter was used to compute the test statistic. In general, unless there is strong reason to do otherwise, we recommend the use of equally spaced dose levels when applying the Poisson or robust Poisson test for trend.

View description>>

Transpiration element is included in the integrated stomatal conductance-photosynthesis model by considering gaseous transfer processes, so the present model is capable to simulate the influence of boundary layer conductance. Leuning in his revised Ball's model replaced relative humidity with VPDs(the vapor pressure deficit from stomatal pore to leaf surface) and thereby made the relation with transpiration more straightforward, and made it possible for the regulation of transpiration and the influence of boundary layer conductance to be integrated into the combined model. If the differences in water vapor and CO2 concentration between leaf and ambient air are considered, VPDs, the evaporative demand, is influenced by stomatal and boundary layer conductance. The physiological responses of photosynthesis, transpiration, and stomatal function, and the changes of intercellular CO2 and water use efficiency to environmental factors, such as wind speed, photon flux density, leaf temperature and ambient CO2, are analyzed. It is shown that if the boundary layer conductance drops to a level comparable with stomatal conductance, the results of simulation by the model presented here differ significantly from those by the previous model, and, in some cases, are more realistic than the latter.

View description>>

Hydroxyapatite (HAp) coatings are used to improve the adhesion of bone onto implanted devices. This approach increases the integrity and hence the lifetime of the implant. Several orthopaedic appliances (HAp coated and macrotextured) were recovered from patients after revision surgery. The implants were cleaned and sterilised in ethanol or formaldehyde before being photographed and sectioned for analysis. X-ray diffraction indicated that the remaining coating was of high crystallinity. Micro textured areas such as ribbings and fenestrations subjected the coating to different modes of stress which has affected the coating. Adhesive failure was evident on implants attributed to dissolution of the amorphous phase at the interface. Observation of the microstructure with scanning electron microscopy showed that coating degradation begins at the surface where the coating is resorbed and continues along the substrate-coating interface thereby compromising interface strength. The microstructure and the dissolution of retrieved implants are discussed in relation to the general coating features in plasma sprayed HAp coatings.

The paper provides a numerical comparison of local risk minimisation and mean-variance hedging for some key variations of stochastic volatility models. A hedging and pricing framework is established for both approaches. Important quantitative differences become apparent that have implications for the implementation of hedging strategies under stochastic volatility.
