This item is printed on demand - it takes 3-4 days longer - Neuware -The theory of elliptic curves is distinguished by its long history and by the diversity of the methods that have been used in its study. This book treats the arithmetic theory of elliptic curves in its modern formulation, through the use of basic algebraic number theory and algebraic geometry. The book begins with a brief discussion of the necessary algebro-geometric results, and proceeds with an exposition of the geometry of elliptic curves, the formal group of an elliptic curve, and elliptic curves over finite fields, the complex numbers, local fields, and global fields. Included are proofs of the Mordell Weil theorem giving finite generation of the group of rational points and Siegel s theorem on finiteness of integral points.For this second edition of The Arithmetic of Elliptic Curves, there is a new chapter entitled Algorithmic Aspects of Elliptic Curves, with an emphasis on algorithms over finite fields which have cryptographic applications. These include Lenstra s factorization algorithm, Schoof s point counting algorithm, Miller s algorithm to compute the Tate and Weil pairings, and a description of aspects of elliptic curve cryptography. There is also a new section on Szpiro s conjecture and ABC, as well as expanded and updated accounts of recent developments and numerous new exercises.The book contains three appendices: Elliptic Curves in Characteristics 2 and 3, Group Cohomology, and a third appendix giving an overview of more advanced topics. 536 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -There has been dramatic growth in the development and application of Bayesian inference in statistics. Berger (2000) documents the increase in Bayesian activity by the number of published research articles, the number of books,andtheextensivenumberofapplicationsofBayesianarticlesinapplied disciplines such as science and engineering. One reason for the dramatic growth in Bayesian modeling is the availab- ity of computational algorithms to compute the range of integrals that are necessary in a Bayesian posterior analysis. Due to the speed of modern c- puters, it is now possible to use the Bayesian paradigm to t very complex models that cannot be t by alternative frequentist methods. To t Bayesian models, one needs a statistical computing environment. This environment should be such that one can: write short scripts to de ne a Bayesian model use or write functions to summarize a posterior distribution use functions to simulate from the posterior distribution construct graphs to illustrate the posterior inference An environment that meets these requirements is the R system. R provides a wide range of functions for data manipulation, calculation, and graphical d- plays. Moreover, it includes a well-developed, simple programming language that users can extend by adding new functions. Many such extensions of the language in the form of packages are easily downloadable from the Comp- hensive R Archive Network (CRAN). 312 pp. Englisch.

Buch. Condizione: Neu. Chapin, M.C. (illustratore). This item is printed on demand - it takes 3-4 days longer - Neuware -The world is undergoing unprecedented changes in many of the factors that determine its fundamental properties and their in- ence on society. These changes include climate; the chemical c- position of the atmosphere; the demands of a growing human population for food and ber; and the mobility of organisms, ind- trial products, cultural perspectives, and information ows. The magnitude and widespread nature of these changes pose serious challenges in managing the ecosystem services on which society depends. Moreover, many of these changes are strongly in uenced by human activities, so future patterns of change will continue to be in uenced by society's choices and governance. The purpose of this book is to provide a new framework for n- ural resource management-a framework based on stewardship of ecosystems for human well-being in a world dominated by unc- tainty and change. The goal of ecosystem stewardship is to respond to and shape change in social-ecological systems in order to s-tain the supply and opportunities for use of ecosystem services by society. The book links recent advances in the theory of resilience, sustainability, and vulnerability with practical issues of ecosystem management and governance. The book is aimed at advanced undergraduates and beginning graduate students of natural resource management as well as professional managers, community leaders, and policy makers with backgrounds in a wide array of d- ciplines, including ecology, policy studies, economics, sociology, and anthropology. 424 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The SECCHI A and B instrument suites (Howard et al. , 2006) onboard the two STEREO mission spacecraft (Kaiser, 2005) are each composed of: one Extreme Ultra-Violet Imager (EUVI), two white-light coronagraphs (COR1 and COR2), and two wide-angle heliospheric imagers (HI1 and HI2). Technical descriptions of EUVI, COR1 and the HIs can be found in Wuelser et al. (2004), Thompson et al. (2003), and De se et al. (2003), respectively. The images produced by SECCHI represent a data visualization challenge: i) the images are 2048×2048 pixels (except for the HIs, which are usually binned onboard 2×2), thus the vast majority of computer displays are not able to display them at full frame and full r- olution, and ii) more importantly, the ve instruments of SECCHI A and B were designed to be able to track Coronal Mass Ejections from their onset (with EUVI) to their pro- gation in the heliosphere (with the HIs), which implies that a set of SECCHI images that covers the propagation of a CME from its initiation site to the Earth is composed of im- 1 ages with very different spatial resolutions - from 1. 7 arcsecondspixel for EUVI to 2. 15 1 arcminutespixel for HI2, i. e. 75 times larger. A similar situation exists with the angular scales of the physical objects, since the size of a CME varies by orders of magnitude as it expands in the heliosphere. 296 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Bias analysis quantifies the influence of systematic error on an epidemiology study's estimate of association. The fundamental methods of bias analysis in epi- miology have been well described for decades, yet are seldom applied in published presentations of epidemiologic research. More recent advances in bias analysis, such as probabilistic bias analysis, appear even more rarely. We suspect that there are both supply-side and demand-side explanations for the scarcity of bias analysis. On the demand side, journal reviewers and editors seldom request that authors address systematic error aside from listing them as limitations of their particular study. This listing is often accompanied by explanations for why the limitations should not pose much concern. On the supply side, methods for bias analysis receive little attention in most epidemiology curriculums, are often scattered throughout textbooks or absent from them altogether, and cannot be implemented easily using standard statistical computing software. Our objective in this text is to reduce these supply-side barriers, with the hope that demand for quantitative bias analysis will follow. 192 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Sun is nowadays observed using di erent techniques that provide an almost instantaneous 3-D map of its structure. Of particular interest is the studyofthevariabilityinthesolaroutputproducedbythedissipationofm- netic energy on di erent spatial and temporal scales - the so-called magnetic activity. The 11-year cycle is the main feature describing this phenomenon. Apart from its intrinsic scienti c interest, this topic is worth studying because of the interaction of such processes with the terrestrial environment. A eet of space and ground-based observatories are currently monitoring the behaviour of our star on a daily basis. However, solar activity varies not only on this decadal time-scale, as has been attested mainly through two methods: (a) records of the number of sunspots observed on the solar surface from 1610, and (b) the records of 14 10 cosmogenic isotopes, such as Cand Be, measured in tree-rings and i- cores, respectively. The study of the long-term behaviour of solar activity may be comp- mented by the study of historical accounts describing phenomena directly or indirectly related to solar activity. Numerous scienti c and non-scienti c d- uments have reported these events and we can make use of them as a proxy of solar activity in past times. 400 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Evidence now suggests that the roles of essential fatty acids as growth promoters and as indices of health and nutrition are fundamentally similar in freshwater and marine ecosystems. Lipids in Aquatic Ecosystems integrates this divergent literature into a coordinated, digestible form.Chapters are organized so as to discuss and synthesize the flow of lipids from lower to higher trophic levels, up to and including humans. Linkages between the production, distribution and pathways of these essential compounds within the various levels of the aquatic food webs, and their ultimate uptake by humans and other terrestrial organisms, are highlighted throughout the book. This book will be of interest to researchers and resource managers working with aquatic ecosystems. 400 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Androgens are critical regulators of prostate differentiation and function, as well as prostate cancer growth and survival. Therefore, androgen ablation is the preferred systemic treatment for disseminated prostate cancer. Androgen action is exerted in target tissues via binding the androgen receptor (AR), a nuclear receptor transcription factor. Historically, the gene expression program mediated by the AR has been poorly understood. However, recent gene expression profiling and more traditional single-gene characterization studies have revealed many androgen-regulated genes that are important mediators of androgen action in both normal and malignant prostate tissue. This book will focus on the androgen-regulated gene expression program, and examine how recently identified androgen-regulated genes are likely to contribute to the development and progression of prostate cancer. Recent studies that have attempted to unravel how these genes are deregulated in androgen depletion independent prostate cancer will be included 836 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware - 1.1. SAFETY OF CIVIL STRUCTURES Society expects that the failure of civil structures is extremely rare and relies on the care and expertise of the professionals involved in the design, construction and maintenance of structures. This is in particular true for public technical systems such as transportation or energy supply systems and structures such as bridges. Structural safety may be defined as follows: 'Adequate safety with respect to a hazard is ensured provided that the hazard is kept under control by appropriate measures or the risk is limited to an acceptable value. Absolute safety is not achievable.' It is thus not the structure as such that is designated safe but rather the people, goods and the environment in its surroundings. The continued use of existing structures is of great importance because the built environment is a huge economic and political asset, growing larger every year. Nowadays evaluation of the safety of existing structures is a major engineering task, and structural engineers are increasingly called upon to devise ways for extending the life of structures whilst observing tight cost constraints. Also, existing structures are expected to resist against accidental actions although they were not designed for. Engineers may apply specific methods for evaluation in order to preserve structures and to reduce a client's expenditure. The ultimate goal is to limit construction intervention to a minimum, a goal that is clearly in agreement with the principles of sustainable development.

GardinerPlant Genetics and Genomics: Crops and Models book series provides current overviews and summaries of the state of the art in genetics and genomics for each of the important crop plants and genetic models for which such a volume does not now exist or is out of date. Volumes will focus on a single crop, species, or group of close relatives, including especially those plants that already have advanced genomic resources developed and preferably complete or advancing genome sequences.The Rosaceae Family includes many significant fruit, nut, ornamental and wood crops. Traditionally their large stature, long juvenility periods, and often complicated genomes presented little opportunity for genetic or genomic inquiry. But the new millennium brings with it new challenges to production of the highly desirable products from this family, challenges that genetic and genomic tools may help resolve. Together necessity and scientific curiosity conspire to launch deep exploration of rosaceous crop biology. This volume originates at an acceleration point for Roscaeae genomics. A foundation of outstanding tools has been developed in a cross-section of species. The successes and failures of various approaches have been documented from model systems and inform our attack on questions within the valued crops within the Rosaceae. The text within describes the species and products of this plant family along with a synopsis of the current state of research presented from experts active on the front line of Rosaceae genomics research.Kevin M. Folta is a native of Chicago, Illinois USA. Kevin completed his Ph.D. work in identification of blue light regulated promoter elements and post-transcriptional light-regulated mRNA stability at the University of Illinois at Chicago. Postdoctoral work at the University of Wisconsin centered on light regulated electrophysiology, gene expression and high-resolution growth monitoring. Kevin has maintained a unique research program in photomorphogenesis and a separate emphasis in strawberry genomics at the University of Florida in Gainesville, FL. He is active in public science education and has won awards for dedication to undergraduate research.Susan E. Gardiner grew up on a sheep farm in Christchurch, New Zealand. Home schooled as a child, Sue later obtained both her undergraduate degree and PhD in Biochemistry from Otago University in Dunedin, New Zealand. Her post-doctoral period was spent in Freiburg, Germany, where she worked to elucidate the mechanism of differential regulation of the enzymes of phenylpropanoid biosynthesis in a parsley cell culture system irradiated with UV light. In 1980, Sue joined the Plant Physiology Division of the Department of Scientific and Industrial Research (DSIR) in Palmerston North, New Zealand where she first worked on the elucidation of chloroplast glycerolipid biosynthesis and later developed techniques for distinguishing varieties of pasture grasses and legumes. Sue's work on gene mapping in apple began in 1990 at DSIR and continued when DSIR was restructured into HortResearch in 1992. Today, Sue leads a team working to unravel the genetic architecture of traits of fruit cropscentral to New Zealand fruit industries. Technological advancements in Genomics at HortResearchproved to be critical in her success in identification of 'breeder-friendly markers for traits of economic value.' Sue has developed an extensive network of international collaborators in Rosaceae genomics, and recently completed a 2-year term as Chair of the International Rosaceae Genomics Initiative. Sue derives her greatest satisfaction from seeing her team's marker technologies being used by breeders. 656 pp. Englisch.
