Buch. Condizione: Neu. Neuware - The idea of using functionals of Information Theory, such as entropies or divergences, in statistical inference is not new. However, in spite of the fact that divergence statistics have become a very good alternative to the classical likelihood ratio test and the Pearson-type statistic in discrete models, many statisticians remain unaware of this powerful approach.Statistical Inference Based on Divergence Measures explores classical problems of statistical inference, such as estimation and hypothesis testing, on the basis of measures of entropy and divergence. The first two chapters form an overview, from a statistical perspective, of the most important measures of entropy and divergence and study their properties. The author then examines the statistical analysis of discrete multivariate data with emphasis is on problems in contingency tables and loglinear models using phi-divergence test statistics as well as minimum phi-divergence estimators. The final chapter looks at testing in general populations, presenting the interesting possibility of introducing alternative test statistics to classical ones like Wald, Rao, and likelihood ratio. Each chapter concludes with exercises that clarify the theoretical results and present additional results that complement the main discussions.Clear, comprehensive, and logically developed, this book offers a unique opportunity to gain not only a new perspective on some standard statistics problems, but the tools to put it into practice.…

Buch. Condizione: Neu. Neuware - Toxicology of Reptiles cohesively summarizes much of the cutting-edge research taking place in fields such as reptilian endocrinology, neurophysiology, immunology, and ecology. It also addresses conservation needs along with the complications often associated with population studies. The text is easy to synthesize and apply in the evaluation and understanding of potential risks to reptiles from environmental contaminants.This book provides a comprehensive description of the current state of knowledge of reptilian toxicology from the perspective of target organ systems. It covers major contaminant classes within each chapter, focusing on those of greatest concern. The authors highlight the most pressing information gaps, and propose priority directions for further advancement in the fields of reptilian biology, wildlife and environmental toxicology, conservation, and ecological risk assessment.…

Buch. Condizione: Neu. Neuware - This volume discusses questions of free-radical biology and new, modern directions in molecular cytobiology; proteomics and genomics. The book presents articles and reviews on bioantioxidants, synthesis of new compounds, mechanisms of their action and areas of application. Studies on free radical states using ESR technique, biochemistry of regulatory systems and the role of free radicals in radiation disease and cancer development are given special attention. Test results of new drugs for curing malignant tumors and kinetic approaches to the description of disease development and estimation of curative action of medicinal preparations are shown. The book also presents studies in the branch of enzymology, receptor systems, photoreception, in particular. The volume uniquely presents general tendencies in chemistry, biology and medicine kinetically united and attached to free radical mechanisms and other questions under consideration.…

Buch. Condizione: Neu. Neuware - Since its discovery, Atomic Force Microscopy (AFM) has become a technique of choice for non-destructive surface characterization with sub-molecular resolution. The AFM has also emerged as a problem-solving tool in applications relevant to particle-solid and particle-liquid interactions, design, fabrication, and characterization of new materials, and development of new technologies for processing and modification of materials. This volume is a comprehensive review of AFM techniques and their application in adhesion studies. It is intended for both researchers and students in engineering disciplines, physics and biology. Over 100 authors contributed to this book, summarizing current status of research on measurements of colloidal particle-solid adhesion and molecular forces, solid surface imaging and mapping, and discussing the contact mechanics models applicable to particle-substrate and particle-particle systems.…
