Buch. Condizione: Neu. Neuware - Where do you begin to look for a recent, authoritative article on the diagnosis or management of a particular malignancy The few general oncology textbooks are generally out of date. Single papers in specialized journals are informative but seldom comprehensive; these are more often preliminary reports on a very limited number of patients. Certain general journals frequently publish good in-depth reviews of cancer topics, and published symposium lectures are often the best overviews available. Unfor tunately, these reviews and supplements appear sporadically, and the reader can never be sure when a topic of special interest will be covered. Cancer Treatment and Research is a series of authoritative volumes that aim to meet this need. It is an attempt to establish a critical mass of oncology literature covering virtually all oncology topics, revised frequently to keep the coverage up to date, easily available on a single library shelf or by a single personal subscription. We have approached the problem in the following fashion: first, by dividing the oncology literature into specific subdivisions such as lung can cer, genitourinary cancer, and pediatric oncology; second, by asking emi nent authorities in each of these areas to edit a volume on the specific topic on an annual or biannual basis. Each topic and tumor type is covered in a volume appearing frequently and predictably, discussing current diagnosis, staging, markers, all forms of treatment modalities, basic biology, and more.

Buch. Condizione: Neu. Neuware - Research at the molecular and the cellular level has greatly enhanced our understanding of the pathogenesis and management of heart disease. Valuable contributions, towards this end, have been made by scientists from different dis ciplines including biochemistry, physiology, pathology, molecular biology and biophysics. We felt that it would be of interest and value to bring together ex perts from diverse specialities to present their work and to discuss the common problems encountered in their endeavours. In accordance, a symposium was organised in February 1988 at the Postgraduate Institute of Medical Education & Research, Chandigarh. It was held during the annual meeting of the Indian section of the International Society for Heart Research. This book is a compila tion of some of the papers presented at the symposium. The symposium was sponsored by the Council on Cardiac Metabolism of the International Society and Federation of Cardiology. A number of Indian or ganisations gave generous financial help. These included the National Academy of Medical Sciences, Indian Council of Medical Research, Council of Scientific and Industrial Research and Department of Science and Technology. Desktop publishing was used to prepare this volume. In doing so we came to appreciate the remarkable qualities, skills and help rendered by Professor Dharam Vir. For typing the manuscripts and for other secretarial assistance we gratefully acknowledge the help of Ravinder and Sawtantar.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Cryptology is the art and science of secure communication over insecure channels. The primary aim of this book is to provide a self-contained overview of recent cryptologic achievements and techniques in a form that can be understood by readers having no previous acquaintance with cryptology. It can thus be used as independent reading by whoever wishes to get started on the subject. An extensive bibliography of 250 references is included to help the reader deepen his or her understanding and go beyond the topics treated here. This book can also be used as preliminary material for an introductory course on cryptology. Despite its simplicity, it covers enough state-of-the-art material to be nevertheless of interest to the specialist. After a survey of the main secret and public key techniques, various applications are discussed. The last chapter describes 'quantum cryptography', a revolutionary approach to cryptography that remains secure even against an opponent with unlimited computing power. Quantum crytography is based on the principles of quantum physics. 120 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The simultaneous inclusion of polynomial complex zeros is a crucial problem in numerical analysis. Rapidly converging algorithms are presented in these notes, including convergence analysis in terms of circular regions, and in complex arithmetic. Parallel circular iterations, where the approximations to the zeros have the form of circular regions containing these zeros, are efficient because they also provide error estimates. There are at present no book publications on this topic and one of the aims of this book is to collect most of the algorithms produced in the last 15 years. To decrease the high computational cost of interval methods, several effective iterative processes for the simultaneous inclusion of polynomial zeros which combine the efficiency of ordinary floating-point arithmetic with the accuracy control that may be obtained by the interval methods, are set down, and their computational efficiency is described. The rate of these methods is of interest in designing a package for the simultaneous approximation of polynomial zeros, where automatic procedure selection is desired. The book is both a text and a reference source for mathematicans, engineers, physicists and computer scientists who are interested in new developments and applications, but the material is also accessible to anyone with graduate level mathematical background and some knowledge of basic computational complex analysis and programming. 280 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Safe surgery is founded upon careful dissection and clear identification of vital structures. Knowledge of the appropriate anatomy and anatomical relations is therefore essential, not only during surgical training, but as the cornerstone of surgical practice. The aim of this book is to describe the essential anatomical basis of a range of common procedures in general and vascular surgery. The large-format multi-volume texts on operative surgery, despite their undoubted excellence, are now too expensive for individual purchase. Single-volume books on operative surgery have been unable to devote sufficient attention to anatomical detail and the surgeon is left ploughing through anatomy texts, often failing to find illustrations which demonstrate clearly the features that are important in an operative dissection. The present text highlights features of the operations which are important anatomically while not attempting to give a complete description of the operative procedure. A combination of line diagrams and cross sections has been used to provide the topographical detail. The volume is aimed mainly at surgeons in training, to help them on a day-to day basis and to provide a text which will be useful in revising for post graduate examinations in surgery. It is also hoped that the book will be of use to practising surgeons, providing an easy means of highlighting important anatomical aspects of the procedures they perform relatively infrequently. 1989 S.J.S. 100 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book which is the outcome of a NATO-Advanced Study Institute on Mod elling the Ocean Circulation and Geochemical Tracer Transport is concerned with using models to infer the ocean circulation. Understanding our climate is one of the major problems of the late twentieth century. The possible climatic changes resulting from the rise in atmospheric carbon dioxide and other trace gases are of primary interest and the ocean pla. ys a ma. jor role in determining the magnitude, temporal evolution and regional distribution of those changes. Because of the poor observational basis the ocean general circulation is not well understood. The World Ocean Circulation Experiment (WOCE) which is now underway is an attempt to improve our knowledge of ocean dynamics and thermodynamics on global scales relevant to climate change. Despite those efforts, the oceanic data base is likely to remain scarce and it is crucial to use appropriate methods in order to extract the maximum amount of information from observations. The book contains a thorough analysis of methods to combine data of val'ious types with dynamical concepts, and to assimilate data directly into ocean models. The properties of geocl;temical tracers such as HC, He, Tritium and Freons and how they may be used to impose integral constraints on the ocean circulation are discussed. 632 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This work relates different approaches for the modelling of parallel processes. On the one hand there are theso-called 'process algebras' or 'abstract programming languages' with Milner's Calculus of Communicating Systems (CCS) and the theoretical version of Hoare's Communicating Sequential Processes (CSP) as main representatives. On the other hand there are machine models, i.e. the classical finite state automata (transition systems), for which, however, more discriminating notions of equivalence than equality of languages are used; and secondly, there are differently powerful types of Petri nets, namely safe and general (place/transition) nets respectively, and predicate/transition nets. Within a uniform framework the syntax and the operational semantics of CCS and TCSP are explained. We consider both, Milner's well-known interleaving semantics, which is based on infinite transition systems, as well as the new distributed semantics introduced by Degano et al., which is based on infinite safe nets. The main part of this work contains three syntax-driven constructions of transition systems, safe nets, and predicate/transition nets respectively. Each of them is accompanied by a proof of consistency. Due to intrinsic limits, which are also investigated here, neither for transition systems and finite nets, nor for general nets does a finite consistent representation of all CCS and TCSP programs exist. However sublanguages which allow finite representations are discerned. On the other hand the construction of predicate/transition nets is possible for all CCS programs in which every choice and every recursive body starts sequentially. 184 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This monograph considers stochastic models for laser propagation in atmospheric turbulence in a Hilbert space context. The laser beam intensity is formulated as the solution to a random Schroedinger equation. This model is considered as an abstract bilinear system with a multiplicative white noise input. This monograph applied the Hilbert space valued white noise theory to the laser distortion problem and relates it to the Wiener process formulation. This monograph will be of interest to researchers working in stochastic differential equations, as well as engineers and physicists working in atmoshperic optics. The monograph is intended for readers who have taken a graduate course in functional analysis and probability. 160 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The ESPRIT Project 1072, DIAMOND (Development and Integration of Accurate Mathematical Operations in Numerical Data-Processing) was carried out from January 1986 through April 1989 by the five partners Siemens Miinchen (prime contractor), CWI Amsterdam, University of Karlsruhe (Institut fiir Ange wandte Mathematik), NAG Oxford and University of Bath (subcontractor to NAG). The technical work was divided into three main work packages with one additional work package for miscellaneous topics. The major goals of this project, according to its title, were to develop a set of accurate numerical algorithms (work package 3) and to provide tools to support their implementation by means of an embedding of accurate arithmetic into programming languages (work package 1) and by transform ation techniques which either improve the accuracy of expression evaluation or detect and eliminate presumable deficiencies in accuracy in existing programs (work package 2). A great variety of working papers describing and discussing the results of these work packages have been written during the collaboration of the project. This book (Accurate Numericlll A 19oritltms) mainly summarizes the results of work package 3, carried through by the two partners Karlsruhe University and NAG Oxford under the leadership of the editors and Dr. G. S. Hodgson. Another book (Improving Floating-Point Programming, J. Tliley, to appear 1989), edited by P.J.L. Wallis, which is one of the DIAMOND project's final deliverables, concentrates more on the fundamental tools. 248 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This monograph evolved over the past five years. It had its origin as a set of lecture notes prepared for the Ninth Summer School of Mathematical Physics held at Ravello, Italy, in 1984 and was further refined in seminars and lectures given primarily at the University of Colorado. The material presented is the product of a single mathematical question raised by Dave Kassoy over ten years ago. This question and its partial resolution led to a successful, exciting, almost unique interdisciplinary col laborative scientific effort. The mathematical models described are often times deceptively simple in appearance. But they exhibit a mathematical richness and beauty that belies that simplicity and affirms their physical significance. The mathe matical tools required to resolve the various problems raised are diverse, and no systematic attempt is made to give the necessary mathematical background. The unifying theme of the monograph is the set of models themselves. This monograph would never have come to fruition without the enthu siasm and drive of Dave Eberly-a former student, now collaborator and coauthor-and without several significant breakthroughs in our understand ing of the phenomena of blowup or thermal runaway which certain models discussed possess. A collaborator and former student who has made significant contribu tions throughout is Alberto Bressan. There are many other collaborators William Troy, Watson Fulks, Andrew Lacey, Klaus Schmitt-and former students-Paul Talaga and Richard Ely-who must be acknowledged and thanked. 196 pp. Englisch.
