Points fixes, zéros et la méthode de Newton = Fixed points, zeros and Newton's method

This work is devoted to the fixed points of differentiable applications, to the zeros of non-linear systems and to Newton's method. It is aimed at masters students or preparing for the aggregation of mathematics and confirmed researchers. The first part is devoted to the method of successive approximations and confronts a “dynamical systems” point of view (Grobman-Hartman theorems, of the stable manifold) with examples resulting from numerical analysis. The second part of this work presents Newton's method and its most recent developments (Smale's alpha theory, under- or over-determined systems). It presents a new approach to this subject and a set of original results published for the first time in a French-language work. This is an advanced text on fixed points, zeros of nonlinear systems and the Newton method. Its first part, devoted to fixed points, includes the Grobman-Hartman and the stable manifold theorems. The second part describes the Newton method from a modern point of view: Smale's alpha theory, underdetermined and overdetermined systems of equations. These results are illustrated by various examples from numerical analysis.

Platelet Function : Assessment, Diagnosis, and Treatment

Platelet function, or clot formation, is difficult to assess, but extremely important because inadvertent or excessive platelet activation underlies many common cardiovascular disorders, such as myocardial infarction, unstable angina, and stroke. In Platelet Function: Assessment, Diagnosis, and Treatment, a panel of leading researchers and clinicians review the latest findings on the complexities of platelet function and the various means of inhibiting platelet clot formation. The authors delineate an up-to-date picture of platelet biology and describe methods for assessing platelet function, including the commonly used platelet aggregation, thromboxane production, procoagulant function, platelet function under flow, and the expression of platelet activation markers. The focus is both on the technology and the outcome of research on platelets, including the fast developing fields of proteomics and genomics and their application to platelet research. The clinical applications of the various methods for the assessment of platelet function in vivo, as well as antiplatelet therapy, are fully discussed.

Plastics for Corrosion Inhibition

The development of polymer composites containing inhibitors of metal corrosion is an important endeavour in modern materials science and technology. Corrosion inhibitors can be located in a polymer matrix in the solid, liquid or gaseous phase. This book details the thermodynamic principles for selecting these components, their compatibility and their effectiveness. The various mechanisms of metal protection – barrier, inhibiting and electromechanical – are considered, as are the conflicting requirements placed on the structure of the combined material. Two main classes of inhibited materials (structural and films/coatings) are described in detail. Examples are given of structural plastics used in friction units subjected to mechano-chemical wear and of polymer films/coatings for protecting metal objects against corrosion.

Plasticity in the Visual System : From Genes to Circuits

Plasticity is the basis for learning, memory formation and cognition, and the adaptability it affords is essential for normal day-to-day functioning. Many diseases of brain functioning can be described as, or affect, plasticity mechanisms. The goal of Plasticity in the Visual System: From Genes to Circuits is to assemble and integrate the various levels of analysis required to approach a more complete picture of plasticity in the visual system. Researchers with backgrounds varying from systems neuroscience to molecular biology present a coherent picture of visual system plasticity, in which an array of genetic and molecular processes becomes linked with changes in neuronal connectivity, physiological changes, and ultimately, learning behavior. Because of its interdisciplinary view on plasticity, this book will appeal to the wide neuroscience community.

Plant Selection for Bioretention Systems and Stormwater Treatment Practices

As cities develop, more land is converted into impervious surfaces, which do not allow water to infiltrate. Careful urban planning is needed to ensure that the hydrologic cycle and water quality of the catchment areas are not affected. There are techniques that can attenuate peak flow during rain events and reduce the amount of metals, nutrients, and bacteria that enter the urban water cycle. This brief gives a short introduction on bioretention systems and documents the effectiveness of some 36 plant species in removing water pollutants. A summary on the maintenance requirements is also presented.

Plant Respiration : From Cell to Ecosystem

Respiration in plants, as in all living organisms, is essential to provide metabolic energy and carbon skeletons for growth and maintenance. As such, respiration is an essential component of a plant’s carbon budget. Depending on species and environmental conditions, it consumes 25-75% of all the carbohydrates produced in photosynthesis – even more at extremely slow growth rates. Respiration in plants can also proceed in a manner that produces neither metabolic energy nor carbon skeletons, but heat. This type of respiration involves the cyanide-resistant, alternative oxidase; it is unique to plants, and resides in the mitochondria. The activity of this alternative pathway can be measured based on a difference in fractionation of oxygen isotopes between the cytochrome and the alternative oxidase. Heat production is important in some flowers to attract pollinators; however, the alternative oxidase also plays a major role in leaves and roots of most plants. A common thread throughout this volume is to link respiration, including alternative oxidase activity, to plant functioning in different environments.

Planning Demand-Driven Disassembly for Remanufacturing

Ian M. Langella examines the planning of disassembly for remanufacturing of used products, yielding components which are reassembled into “as good as new” items. Through a thorough analysis of the underlying planning problem, fundamental insights are attained and heuristic solution methods are developed and tested. Although the heuristics exhibit good performance, they remain simple enough to be applied to industrial-sized problems. The author considers both settings where yields are deterministic and stochastic and where the amount of returned products is constrained.
