Taschenbuch. Condizione: Neu. Neuware - Philosophy and psychopathology have more in common than philosophers, psychiatrists and clinical psychologists might think. Three fields of inquiry come to mind: (1) Questions about the scientific status of psychopatho logical statements and claims, (2) ethical questions, and (3) problems regarding the question of how to account for something like a disordered mind. While the first two domains have frequently been addressed in articles and debates (think of the mind-body problem and the problem of institutionalization versus self-determination as examples of issues in the two fields), the question of how the mind should be conceived in order for psychopathology to work best has seldom been discussed. The present volume focuses on this question. Perception, thought, affect, will, and the like are terms which made their way from philosophy into psychology, and into present psychiatry, where disturbances of these 'faculties' or 'functions' are believed to form the most basic part of symptomatology. While these terms and many others that are used to refer to symptoms of mental disorder (such as 'self', 'consciousness', 'drive', and 'identity') may seem to be purely descriptive and theoretically 'innocent', they are packed with implicit assumptions, theoretical concepts, and sometimes dogmatic postulates.

Buch. Condizione: Neu. Neuware - Machine Learning is one of the oldest and most intriguing areas of Ar tificial Intelligence. From the moment that computer visionaries first began to conceive the potential for general-purpose symbolic computa tion, the concept of a machine that could learn by itself has been an ever present goal. Today, although there have been many implemented com puter programs that can be said to learn, we are still far from achieving the lofty visions of self-organizing automata that spring to mind when we think of machine learning. We have established some base camps and scaled some of the foothills of this epic intellectual adventure, but we are still far from the lofty peaks that the imagination conjures up. Nevertheless, a solid foundation of theory and technique has begun to develop around a variety of specialized learning tasks. Such tasks in clude discovery of optimal or effective parameter settings for controlling processes, automatic acquisition or refinement of rules for controlling behavior in rule-driven systems, and automatic classification and di agnosis of items on the basis of their features. Contributions include algorithms for optimal parameter estimation, feedback and adaptation algorithms, strategies for credit/blame assignment, techniques for rule and category acquisition, theoretical results dealing with learnability of various classes by formal automata, and empirical investigations of the abilities of many different learning algorithms in a diversity of applica tion areas.

Buch. Condizione: Neu. Neuware - Very large scale integration (VLSI) technologies are now maturing with a current emphasis toward submicron structures and sophisticated applications combining digital as well as analog circuits on a single chip. Abundant examples are found on today's advanced systems for telecom munications, robotics, automotive electronics, image processing, intelli gent sensors, etc . Exciting new applications are being unveiled in the field of neural computing where the massive use of analog/digital VLSI technologies will have a significant impact. To match such a fast technological trend towards single chip ana logi digital VLSI systems, researchers worldwide have long realized the vital need of producing advanced computer aided tools for designing both digital and analog circuits and systems for silicon integration. Ar chitecture and circuit compilation, device sizing and the layout genera tion are but a few familiar tasks on the world of digital integrated circuit design which can be efficiently accomplished by matured computer aided tools. In contrast, the art of tools for designing and producing analog or even analogi digital integrated circuits is quite primitive and still lack ing the industrial penetration and acceptance already achieved by digital counterparts. In fact, analog design is commonly perceived to be one of the most knowledge-intensive design tasks and analog circuits are still designed, largely by hand, by expert intimately familiar with nuances of the target application and integrated circuit fabrication process. The techniques needed to build good analog circuits seem to exist solely as expertise invested in individual designers.

Buch. Condizione: Neu. Neuware - This book, and the research it describes, resulted from a simple observation we made sometime in 1986. Put simply, we noticed that many VLSI design tools looked 'alike'. That is, at least at the overall software architecture level, the algorithms and data structures required to solve problem X looked much like those required to solve problem X'. Unfortunately, this resemblance is often of little help in actually writing the software for problem X' given the software for problem X. In the VLSI CAD world, technology changes rapidly enough that design software must continually strive to keep up. And of course, VLSI design software, and engineering design software in general, is often exquisitely sensitive to some aspects of the domain (technology) in which it operates. Modest changes in functionality have an unfortunate tendency to require substantial (and time-consuming) internal software modifications. Now, observing that large engineering software systems are technology dependent is not particularly clever. However, we believe that our approach to xiv Preface dealing with this problem took an interesting new direction. We chose to investigate the extent to which automatic programming ideas cold be used to synthesize such software systems from high-level specifications. This book is one of the results of that effort.

Buch. Condizione: Neu. Neuware - This book describes a new type of computer aided VLSI design tool, called a VLSI System Planning, that is meant to aid designers dur ing the early, or conceptual, state of design. During this stage of design, the objective is to define a general design plan, or approach, that is likely to result in an efficient implementation satisfying the initial specifications, or to determine that the initial specifications are not realizable. A design plan is a collection of high level design decisions. As an example, the conceptual design of digital filters involves choosing the type of algorithm to implement (e. g. , finite impulse response or infinite impulse response), the type of polyno mial approximation (e. g. , Equiripple or Chebyshev), the fabrication technology (e. g. , CMOS or BiCMOS), and so on. Once a particu lar design plan is chosen, the detailed design phase can begin. It is during this phase that various synthesis, simulation, layout, and test activities occur to refine the conceptual design, gradually filling more detail until the design is finally realized. The principal advantage of VLSI System Planning is that the increasingly expensive resources of the detailed design process are more efficiently managed. Costly redesigns are minimized because the detailed design process is guided by a more credible, consistent, and correct design plan.

Buch. Condizione: Neu. Neuware - The Symposium on New Drugs provides for an annual forum for academic investigators, research and development personnel from the pharmaceutical and related health care industries, and members of the Food and Drug Administration to discuss important clinical research issues. The Tenth Annual Symposium on New Drugs addressed the problem of whether it was still appropriate to approve antihypertensive agents soley on the endpoint of lowering cuff blood pressure. The initial discussions at this symposium related to the approaches and methods to studying antihypertensive agents. Dr. William Frishman provided a detailed list of the new approaches to the treatment of hypertension and pointed out the many new concepts that are currently active in the development of many new antihypertensive agents. Dr. William White detailed the growing importance of ambulatory blood pressure monitoring to define hypertension and to determine the change in blood pressure due to pharmacologically active agents. Dr. Jay Cohn pointed out the flaws in using cuff blood pressure and detailed the potential virtues of using vascular compliance to identify patients requiring treatment for hypertension. Dr. Thomas Pickering also discussed the potential value of evaluating changes in left ventricular hypertrophy a finding which identifies high risk patients who need to be included in clinical trials. Dr. Michael Weber detailed the issues and suggested refinements in the approaches to clinical trial designs for antihypertensive agents and Dr. Raymond Lipicky discussed the definition of dose-duration and the role of non-Mem and Peak/Through measurements in defining an antihypertensive drug effect.

Buch. Condizione: Neu. Neuware - If you have ever hiked up a steep hill to reach a viewpoint, you will know that sensing can involve the expenditure of effort. More generally, the choice of which movement an intelligent system chooses to make is usually based on information gleaned from sensors. But the information required to make the motion decision may not be immediately to hand, so the system . first has to plan a motion whose purpose is to acquire the needed sensor information. Again, this conforms to our everyday experience: I am in the woods and don't know which direction to go, so I climb up to the ridge to get my bearings; I am lost in a new town, so I plan to drive to the next junction where there is sure to be a roadsign, failing that I will ask someone who seems to be from the locality. Why, if experiences such as these are so familiar, has the problem only recently been recognised and studied in Robotics One reason is that until quite recently Robotics research was dominated by work on robot arms with limited reach and fixed in a workcell.

Buch. Condizione: Neu. Neuware - Bone marrow transplantation has emerged as a major form of treatment for a broad range of human diseases. Marrow transplantation has many unique biologic features and its principles differ markedly from the transplantation of solid organs. This volume overviews the present status of bone marrow transplantation and summarizes recent progress and controversies. Ad vances in defining the underlying biology of marrow transplantation are discussed. The current status of several major clinical problem areas are reviewed, including engraftment, acute and chronic graft-versus-host dis ease, immunodeficiency, and opportunistic infections. The therapeutic role of allogeneic and autologous bone marrow transplantation is discussed, and results are compared with alternative therapies. lX List of contributors ANASETII, CLAUDIO, M.

Buch. Condizione: Neu. Neuware - The early history and development of the field of glycolipids was concerned mainly with the predominant glycolipids found in higher animal tissues, namely the glycosphingolipids, as has been extensively documented by J. N. Kanfer and S. Hakomori in Volume 3 of this series. The major glycolipids in organisms of the plant kingdom, however, such as bacteria, yeasts and fungi, algae, and higher plants, are glycoglycerolipids, although glycosphingolipids are also present as minor components in these organisms, except for bacteria. It is of interest that one of the pioneers in glycosphingolipid research, Herbert E. Carter, also pioneered the discovery and structural elucidation of the plant galactosyldiacylglycerols. This class of glycolipids is present in chlo roplast membranes and must surely be one of the most ubiquitous and abun dant natural substances in the world, thereby deserving the attention of lipid biochemists. It is therefore surprising to learn that in contrast to the glycosphingolipids, which were discovered in the 1870s, glycoglycerolipids were not discovered until the 1950s. Since that time investigations of the structure and distribution of these glycolipids have proceeded at an exponen tially increasing rate, and much information is now available for representa tives of many genera of bacteria, yeasts, algae, and higher plants. Glycoglyce rolipids have also been identified in animal cells, particularly in the brain, testes, and sperm.

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 text books 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. Unfortunately, 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, and 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 cancer, genitourinary cancer, pediatric oncology, etc.; and second, by asking eminent 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 - The evaluation of the efficacy and safety of a clinical tool, be it a diagnostic technique, a preventive methodology, or a therapeutic intervention, is an im portant responsibility of physicians. The history of medicine is characterized by the authoritarianisms of teachers and of organizations giving way to the clinical experience of physicians; authoritarian dictum was replaced by case report and then by case series. As physicians learned to substitute the analysis of data for the inconsistencies of dictums and anecdotes, the problems of the case series as an investigative tool became more evident: patient selection criteria, measurements of outcome, significance of results, and extrapolation of conclusions to the community of patients. In response to these issues, the methodology of the controlled clinical trial has evolved and with it the instru ments of study design and of biostatistics as aids to study design and data analysis. The medical - surgical armamentarium has evolved from being dependent solely upon the observations and conclusions of a skilled clinician to being constructed upon the systematic collection and evaluation of data by a team of skilled clinicians and their statistical colleagues: this is the controlled clinical trial. During the past two decades, the evaluation of clinical approaches to pre vention and therapy has become particularly important to clinicians concerned with nervous system dysfunction. There has been and continues to be an explosion of information from the basic neurosciences and from the applica tion of biotechnology to the nervous system.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this monograph on twistor theory and its applications to harmonic map theory, a central theme is the interplay between the complex homogeneous geometry of flag manifolds and the real homogeneous geometry of symmetric spaces. In particular, flag manifolds are shown to arise as twistor spaces of Riemannian symmetric spaces. Applications of this theory include a complete classification of stable harmonic 2-spheres in Riemannian symmetric spaces and a Bäcklund transform for harmonic 2-spheres in Lie groups which, in many cases, provides a factorisation theorem for such spheres as well as gap phenomena. The main methods used are those of homogeneous geometry and Lie theory together with some algebraic geometry of Riemann surfaces. The work addresses differential geometers, especially those with interests in minimal surfaces and homogeneous manifolds. 124 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is a monograph on the fluctuational theory of superconductivity. The theory was originally developed by M. A. Savchenko in 1964 in response to the work of B. T. Matthias, the discoverer of superconductive compounds. Further development of the theory led to the prediction of the existence of high-temperature superconductors among magnetic and nonmagnetic compounds of rare-earth metals, ceramics, and polymers. In 1987 this prediction was experimentally verified by the discovery of high-Tc superconducting rare-earth metal oxides by I. Bednorz and K. Muller. To date, this is the only account that explains consistently all the available data. The theory of high-temperature superconductivity is based on the concept of an enhanced electron-phonon interaction which leads to an attraction between electrons forming superconducting pairs. This interaction is due to the exchange spin fluctu ations (exchange enhancement effect). In compounds in which there is no magnetic ordering except at very low temperatures, such as in rare-earth metal oxides, the electron-phonon interaction is strengthened due to fluctuations in the spins of the conducting electrons. If there is magnetic ordering in a superconductor at a tempera ture higher than or of the same order as the critical superconducting temperature Tc, then the attraction in the electron pairs will be further increased because the Coulomb repulsion is overwhelmed by fluctuations in the spins forming the long-range anti fer romagnetic order. 272 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -An elective course in the final-year BEng progamme in electronic engin eering in the City Polytechnic of Hong Kong was generated in response to the growing need of local industry for graduate engineers capable of designing circuits and performing measurements at high frequencies up to a few gigahertz. This book has grown out from the lecture and tutorial materials written specifically for this course. This course should, in the opinion of the author, best be conducted if students can take a final-year design project in the same area. Examples of projects in areas related to the subject matter of this book which have been completed successfully in the last two years that the course has been run include: low-noise amplifiers, dielectric resonator-loaded oscillators and down converters in the 12 GHz as well as the 1 GHz bands; mixers; varactor-tuned and non-varactor-tuned VCOs; low-noise and power amplifiers; and filters and duplexers in the 1 GHz, 800 MHz and 500 MHz bands. The book is intended for use in a course of forty lecture hours plus twenty tutorial hours and the prerequisite expected of the readers is a general knowledge of analogue electronic circuits and basic field theory. Readers with no prior knowledge in high-frequency circuits are recom mended to read the book in the order that it is arranged. ~ ______ In_t_ro_d_u_c_tl_ o_n ______ ~1 ~ 1. 240 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Civil engineering structures tend to be fabricated from materials that respond elastically at normal levels of loading. Most such materials, however, would exhibit a marked and ductile inelasticity if the structure were overloaded by accident or by some improbable but naturally occuring phenomeon. Indeed, the very presence of such ductility constitutes an important safety provision for large-scale constructions where human life is at risk. In the comprehensive evaluation of safety in structural design, it is therefore unrealistic not to consider the effects of ductility. This book sets out to show that the bringing together of the theory and methods of mathematical programming with the mathematical theory of plasticity furnishes a model which has a unifying theoretical nature and is entirely representative of observed structural behaviour. The contents of the book provide a review of the relevant aspects of mathematical programming and plasticity theory, together with a detailed presentation of the most interesting and potentially useful applications in both framed and continuum structures: ultimate strength and elastoplastic deformability; shakedown and practical upper bounds on deformation measures; evolutive dynamic response; large displacements and instability; stochastic and fuzzy programming for representing uncertainty in ultimate strength calculations. Besides providing a ready fund of computational algorithms, mathematical programming invests applications in mechanics with a refined mathematical formalism, rich in fundamental theorems, which often gives addi- tional insight into known results and occasionally lead to new ones. In addition to its obvious practical utility, the educational value of the material thoroughly befits a university discipline. 448 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Many times there are subjects which demand further explanations and guid ance written about them. Such is the case with SGML, the Standard Generalized Markup Language; and ISO Standard published in October, 1986 under the number 8879. There have been many conferences given on this topic, world-wide, as the interest in SGML exists in Europe, the US, Australia and Japan. This book is the first which contains information not only on ISO 8879 itself, but many helpful hints and ideas on developing SGML, applications and discussions of the current software written to be conforming to the ISO standard. 'Ibis book is critical for any end-user and application developer to understand the many issues neccessary to develop SGML implementations (software selection is one of the topics discussed) and SGML applications. A number of examples of the applications of SGML in various situations are discussed and one can expect that the book will stimulate further discussion of these. This book is a practical guide to various components of the language and the author's experience in development and worldng with SGML in his position as leader of the text processing section at CERN ensures that the guidance is based on practical first-hand experience at an installation with a large number of end-users of very varied experience. 328 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Important results on the Hilbert modular group and Hilbert modular forms are introduced and described in this book. In recent times, this branch of number theory has been given more and more attention and thus the need for a comprehensive presentation of these results, previously scattered in research journal papers, has become obvious. The main aim of this book is to give a description of the singular cohomology and its Hodge decomposition including explicit formulae. The author has succeeded in giving proofs which are both elementary and complete. The book contains an introduction to Hilbert modular forms, reduction theory, the trace formula and Shimizu's formulae, the work of Matsushima and Shimura, analytic continuation of Eisenstein series, the cohomology and its Hodge decomposition. Basic facts about algebraic numbers, integration, alternating differential forms and Hodge theory are included in convenient appendices so that the book can be used by students with a knowledge of complex analysis (one variable) and algebra. 268 pp. Englisch.

Malformations, tumours, more frequently trauma, rheuma tism, and even plain neck pain require a radiological exam ination. The interpretation of radiological images is often difficult because of overlapping pieces of bone, the summation phe nomena and the diversity of projections. In this book, two- or three-dimensional CTscans accompany the standard radiographs, serving as an excellent aid for com prehension. It is almost as if the reader actually had the bones shown in the radiographs in his hands.
