Taschenbuch. Condición: Neu. Neuware -Complex dynamics is today very much a focus of interest. Though several fine expository articles were available, by P. Blanchard and by M. Yu. Lyubich in particular, until recently there was no single source where students could find the material with proofs. For anyone in our position, gathering and organizing the material required a great deal of work going through preprints and papers and in some cases even finding a proof. We hope that the results of our efforts will be of help to others who plan to learn about complex dynamics and perhaps even lecture. Meanwhile books in the field a. re beginning to appear. The Stony Brook course notes of J. Milnor were particularly welcome and useful. Still we hope that our special emphasis on the analytic side will satisfy a need. This book is a revised and expanded version of notes based on lectures of the first author at UCLA over several Vinter Quarters, particularly 1986 and 1990. We owe Chris Bishop a great deal of gratitude for supervising the production of course notes, adding new material, and making computer pictures. We have used his computer pictures, and we will also refer to the attractive color graphics in the popular treatment of H. -O. Peitgen and P. Richter. We have benefited from discussions with a number of colleagues, and from suggestions of students in both our courses.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 192 pp. Englisch.

Buch. Condición: Neu. Neuware -Due to the worldwide epidemic of acquired immunodeficiency syndrome (AIDS), the past ten years have witnessed a flurry of activity in the chemotherapy of viral diseases. Unprecedented scientific efforts have been made by scientists and clinicians to combat infections of human immunodeficiency virus (HIY), the causative agent. Looking back over the past ten years, we have made remarkable progress toward the treatment of the viral disease: isolation of HIV only two years after the identification of the disease, plus major strides in the areas of the molecular biology and virology of the retrovirus, etc. More remarkably, the discovery of the chemotherapeutic agent AZT (Retrovir) was made within two years after the isolation and identification of the virus, followed by unprecedented drug development efforts to culminate in the FDA approval of AZT in twenty-three months, which was a record-breaking time for approval of any drug for a major disease. The last six to seven years have particularly been an exciting and productive period for nucleoside chemists. Since the activity of AZI' was established in 1985, nucleoside chemists have had golden opportunities to discover additional anti-HIV nucleosipes, which are hoped to be less toxic and more effective than AZT, and the opportunity continues. As we all are aware, AZT possesses extremely potent anti-HIY activity, and no other nucleoside or non nucleoside has surpassed the potency of AZT in vitro. 352 pp. Englisch.

Buch. Condición: Neu. Neuware -Elliptic curves have been intensively studied in algebraic geometry and number theory. In recent years they have been used in devising efficient algorithms for factoring integers and primality proving, and in the construction of public key cryptosystems.Elliptic Curve Public Key Cryptosystems provides an up-to-date and self-contained treatment of elliptic curve-based public key cryptology. Elliptic curve cryptosystems potentially provide equivalent security to the existing public key schemes, but with shorter key lengths. Having short key lengths means smaller bandwidth and memory requirements and can be a crucial factor in some applications, for example the design of smart card systems. The book examines various issues which arise in the secure and efficient implementation of elliptic curve systems.Elliptic Curve Public Key Cryptosystems is a valuable reference resource for researchers in academia, government and industry who are concerned with issues of data security. Because of the comprehensive treatment, the book is also suitable for use as a text for advanced courses on the subject.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 148 pp. Englisch.

Buch. Condición: Neu. Neuware -At the age of 6, I discovered a jar of brightly colored shells under my grandmother's kitchen sink. When I inquired where they had come from, she did not answer. Instead, she told me in broken English, 'Ask your mother. ' My mother's response to the same question was, 'Oh, I made them in camp. ' 'Was it fun ' I asked enthusiastically. 'Not really,' she replied. Her answer puzzled me. The shells were beautiful, and camp, as far as I knew, was a fun place where children roasted marshmallows and sang songs around the fire. Yet my mother's reaction did not seem happy. I was perplexed by this brief exchange, but I also sensed I should not ask more questions. As time went by, 'camp' remained a vague, cryptic reference to some time in the past, the past of my parents, their friends, my grand parents, and my relatives. We never directly discussed it. It was not until high school that I began to understand the significance of the word, that camp referred to a World War II American concentration camp, not a summer camp. Much later I learned that the silence surrounding discus sions about this traumatic period of my parents' lives was a phenomenon characteristic not only of my family but also of most other Japanese American families after the war.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 304 pp. Englisch.

Buch. Condición: Neu. Neuware - Parsing technology traditionally consists of two branches, which correspond to the two main application areas of context-free grammars and their generalizations. Efficient deterministic parsing algorithms have been developed for parsing programming languages, and quite different algorithms are employed for analyzing natural language. The Functional Treatment of Parsing provides a functional framework within which the different traditional techniques are restated and unified. The resulting theory provides new recursive implementations of parsers for context-free grammars. The new implementations, called recursive ascent parsers, avoid explicit manipulation of parse stacks and parse matrices, and are in many ways superior to conventional implementations. They are applicable to grammars for programming languages as well as natural languages. The book has been written primarily for students and practitioners of parsing technology. With its emphasis on modern functional methods, however, the book will also be of benefit to scientists interested in functional programming. The Functional Treatment of Parsing is an excellent reference and can be used as a text for a course on the subject.

Buch. Condición: Neu. Neuware - Dean Pomerleau's trainable road tracker, ALVINN, is arguably the world's most famous neural net application. It currently holds the world's record for distance traveled by an autonomous robot without interruption: 21.2 miles along a highway, in traffic, at speedsofup to 55 miles per hour. Pomerleau's work has received worldwide attention, including articles in Business Week (March 2, 1992), Discover (July, 1992), and German and Japanese science magazines. It has been featured in two PBS series, 'The Machine That Changed the World' and 'By the Year 2000,' and appeared in news segments on CNN, the Canadian news and entertainment program 'Live It Up', and the Danish science program 'Chaos'. What makes ALVINN especially appealing is that it does not merely drive - it learns to drive, by watching a human driver for roughly five minutes. The training inputstothe neural networkare a video imageoftheroad ahead and thecurrentposition of the steering wheel. ALVINN has learned to drive on single lane, multi-lane, and unpaved roads. It rapidly adapts to other sensors: it learned to drive at night using laser reflectance imaging, and by using a laser rangefinder it learned to swerve to avoid obstacles and maintain a fixed distance from a row of parked cars. It has even learned to drive backwards.

Buch. Condición: Neu. Neuware - In transfusion medicine the scientific fundamentals of immunology have had a considerable clinical impact. Transfusion may suppress the immunity but some patients could suffer disadvantages including GvHD, alloimmunisation and possible cancer, where white cells (WBC) play pivotal roles in this phenomenon, presenting antigens and producing cytokines. A clinical application of this practice is LAK-cells targeted against cancer. MHC on the WBC may provide additional immunological modulations through series of secondary messengers. Thus reduction of WBC in the blood and bone marrow may be advantageous for patients. On the other hand, sharing a part of MHC or making the transplanted white cells anergic by storage may be even more advantageous for patients. CMV infection could mimic part of this MHC. UV radiation is effective in the inactivation of the WBC although filters are easy means for such removal. However, their accurate quantification requires flow cytometry that has considerable potential application in blood transfusions. Idiotypic antibody could play an important role in platelet theory. However, the potential infection risks in transfusion like HIV and HCV remain, but application of molecular biological methods like PCR or RT/PCR has great potentials in detection of infectious diseases, transplantation and genetic disorders. Immuno affinity purified concentrates, like factor IX and protein C, could reduce patients' immune functions, where in the future protein C could be derived from transgenic animals. Advances are sure to emerge through adoptive immunotherapy and gene therapies are exciting prospects when genes transferred into lymphocytes could be used to correct cell mediated immune deficiency, as in ADA.

Buch. Condición: Neu. Neuware - Multiprocessing: Trade-Offs in Computation and Communication presents an in-depth analysis of several commonly observed regular and irregular computations for multiprocessor systems. This book includes techniques which enable researchers and application developers to quantitatively determine the effects of algorithm data dependencies on execution time, on communication requirements, on processor utilization and on the speedups possible. Starting with simple, two-dimensional, diamond-shaped directed acyclic graphs, the analysis is extended to more complex and higher dimensional directed acyclic graphs. The analysis allows for the quantification of the computation and communication costs and their interdependencies. The practical significance of these results on the performance of various data distribution schemes is clearly explained. Using these results, the performance of the parallel computations are formulated in an architecture independent fashion. These formulations allow for the parameterization of the architecture specitific entities such as the computation and communication rates. This type of parameterized performance analysis can be used at compile time or at run-time so as to achieve the most optimal distribution of the computations. The material in Multiprocessing: Trade-Offs in Computation and Communication connects theory with practice, so that the inherent performance limitations in many computations can be understood, and practical methods can be devised that would assist in the development of software for scalable high performance systems.

Buch. Condición: Neu. Neuware -In recent years, III-V devices, integrated circuits, and superconducting integrated circuits have emerged as leading contenders for high-frequency and ultrahigh speed applications. GaAs MESFETs have been applied in microwave systems as low-noise and high-power amplifiers since the early 1970s, replacing silicon devices. The heterojunction high-electron-mobility transistor (HEMT), invented in 1980, has become a key component for satellite broadcasting receiver systems, serving as the ultra-low-noise device at 12 GHz. Furthermore, the heterojunction bipolar transistor (HBT) has been considered as having the highest switching speed and cutoff frequency in the semiconductor device field. Initially most of these devices were used for analog high-frequency applications, but there is also a strong need to develop high-speed III-V digital devices for computer, telecom munication, and instrumentation systems, to replace silicon high-speed devices, because of the switching-speed and power-dissipation limitations of silicon. The potential high speed and low power dissipation of digital integrated circuits using GaAs MESFET, HEMT, HBT, and superconducting Josephson junction devices has evoked tremendous competition in the race to develop such technology. A technology review shows that Japanese research institutes and companies have taken the lead in the development of these devices, and some integrated circuits have already been applied to supercomputers in Japan. The activities of Japanese research institutes and companies in the III-V and superconducting device fields have been superior for three reasons. First, bulk crystal growth, epitaxial growth, process, and design technology were developed at the same time.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 324 pp. Englisch.

Buch. Condición: Neu. Neuware -TEX has always been regarded as the most elegant and powerful system for computer typesetting. However, its widespread use, beyond academia, was hampered by its complexity. Recently, fairly good TEX implementations have come out for PCs putting TEX on the desks of many people: writers, designers, desktop publishers, engineers, and consequently, the interest in TEX has surged. What is needed at this point is a book that teaches step-by-step how to use TEX, illustrating each step by meaningful examples. This is exactly what S.v. Bechtolsheim's book does. It is a tutorial and guide for the first-time users of TEX, as well as a reference for the most experienced 'TEXpert.' TEX in Practice will appear as a four volume set, starting with volume 1 Basics, followed by volume 2 Paragraphs, Math and Fonts, volume 3 Tokens, Macros and volume 4 Output Routines, Tables. TEX in Practice will be an indispensable reference for the TEX community and a guide through the first steps for the TEX novice.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 436 pp. Englisch.

Buch. Condición: Neu. Neuware -Lead-based paint has become a national issue and will continue to be a hi- priority focus ofnational, state, and local agencies until there is no lead-based paint in the United States. Lead-based paint has become a tremendous health hazard for people and animals. Lead-based paint has been in widespread use throughout Europe and the United States. Lead has been known to be a health hazard since the time ofPliny the Elder (A. D. 23¿79), but it was deemed that the advantages of lead in paint outweighed the health hazards. There has been a change in outlook, and in 1973 the U. S. Congress banned all lead paint from residential structures. A voluminous number of law suits have been initiated since, and continue to be litigated with the purpose of determining the parties responsible for the lead poisoning of children and others and to exact the indemnities. Lead-based paint is still authorized for use on bridges and nonresidential structures, and thousands of city, state, military, and federal government housing projects still contain lead-based paint. This paint must be removed if these dwellings are to be safe living quarters, especially for children. Aba- ment techniques continue to be evaluated; some have been used successfully. Lead-based paint abatement will continue into the next century, and it is hoped that this comprehensive volume will serve as a guide for those seriously interested in this important subject.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 312 pp. Englisch.

In addition to providing mental health professionals, trauma victims, and military personnel with an unparalleled source of information, the work's exploration of the cultural, social, and political processes affecting recovery from combat stress reaction offers a unique perspective of contemporary Isreali culture.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 304 pp. Englisch.

Buch. Condición: Neu. Neuware - The Royal Society has initiated a series of meetings to discuss the effect advances in technology will have on our way of life in the next century. The two previous meetings have been concerned with housing and waste treat ment. The subject of the third meeting, communications, is no less critical to life, but it offers particular problems and uncertainties, especially in the forecasting of future trends. Indeed, some have doubted if there can be profitable debate on long-term development in such a fast-moving field. The importance of the topic justifies an attempt, and the reader will judge whether the authors have met the challenge. Communications today bears little resemblance to that of the 1970s. Then we knew about satellites and optical fibres, and we had seen lasers and silicon chips, but most of us could never imagine the potential of the new technologies within our grasp. We had also not assessed the thirst of the popUlation for more and better ways of talking and writing to each other. It was the combination of market need and technical capability that created the com munications revolution.

Buch. Condición: Neu. Neuware - Effective Polynomial Computation is an introduction to the algorithms of computer algebra. It discusses the basic algorithms for manipulating polynomials including factoring polynomials. These algorithms are discussed from both a theoretical and practical perspective. Those cases where theoretically optimal algorithms are inappropriate are discussed and the practical alternatives are explained. Effective Polynomial Computation provides much of the mathematical motivation of the algorithms discussed to help the reader appreciate the mathematical mechanisms underlying the algorithms, and so that the algorithms will not appear to be constructed out of whole cloth. Preparatory to the discussion of algorithms for polynomials, the first third of this book discusses related issues in elementary number theory. These results are either used in later algorithms (e.g. the discussion of lattices and Diophantine approximation), or analogs of the number theoretic algorithms are used for polynomial problems (e.g. Euclidean algorithm and p-adic numbers). Among the unique features of Effective Polynomial Computation is the detailed material on greatest common divisor and factoring algorithms for sparse multivariate polynomials. In addition, both deterministic and probabilistic algorithms for irreducibility testing of polynomials are discussed.

Buch. Condición: Neu. Neuware - The previous volume of this series on soft tissue sarcomas highlighted the importance of the multidisciplinary approach to treatment, the focus of which is continued in the present edition. Proper diagnosis and staging remain the cornerstone of the treatment strategy. Sophisticated histopathology techniques and growing consensus on grading systems have further increased the importance of the histopathologist in providing estimates of the prognosis of the patient as well as providing data for the planning of treatment strategy. The use of cytogenetics is relatively new in this field. This might enable the distinction of subgroups in specific histological tumor types. Furthermore, molecular biological studies not only help to reveal inherited predispositions and details in oncogenesis in tumor development, but they may also provide additional predictive factors for tumor behavior. Further data on treatment strategy will be provided by diagnostic imaging, a field in which the role of magnetic resonance imaging is rapidly developing. As far as actual treatment is concerned, surgery still provides the major chance for cure. In view of the endeavor to be as sparing as possible, the addition of radiotherapy to surgery is of utmost importance. Usually radiotherapy is given after surgery, but the optimal sequence of the two modalities still needs to be defined. The combined use of surgery with radiotherapy and/or chemotherapy does have an impact on wound healing.

Wearing optical-shutter spectacles and aiming a pulsed laser torch, he will be able to peer at the beating heart, study the movement of a joint or the flexing of a muscle, press on suspect areas to see how the organs beneath respond, check that pills have been correctly swallowed or that an implant is savely in place, and so on. A patient wearing white cotton or nylon clothes that scatter but hardly absorb light, may not even have to undress . . . . -. David Jones, Nature (1990) 348:290 Optical imaging of the brain is a rapidly growing field of heterogenous techniques that has attracted considerable interest recently due to a number of theoretical advantages in comparison with other brain imaging modalities: it uses non ionizing radiation, offers high spatial and temporal resolution, and supplies new types of metabolic and functional information. From a practical standpoint it is important that bedside examinations seem feasible and that the implementations will be considerably less expensive compared with competing techniques. In October 1991, a symposium was held at the Eibsee near Garmisch, Germany to bring together the leading scientists in this new field.

Buch. Condición: Neu. Neuware -Computational neuroscience is best defined by its focus on understanding the nervous systems as a computational device rather than by a particular experimental technique. Accordinlgy, while the majority of the papers in this book describe analysis and modeling efforts, other papers describe the results of new biological experiments explicitly placed in the context of computational issues. The distribution of subjects in Computation and Neural Systems reflects the current state of the field. In addition to the scientific results presented here, numerous papers also describe the ongoing technical developments that are critical for the continued growth of computational neuroscience.Computation and Neural Systems includes papers presented at the First Annual Computation and Neural Systems meeting held in San Francisco, CA, July 26--29, 1992.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 560 pp. Englisch.

Buch. Condición: Neu. Neuware -In our environmentally conscious society, reports of an increase in the risk of developing several cancers - including melanoma, lymphoma and lung cancer - have excited great controversy. Of these tumors, melanoma has demonstrated the most spectacular increase, generating a considerable body of research. The justification for this volume is found in the need for an up-to-date review of this research. The book represents a comprehensive review of both current research and clinical management of melanoma, arranged in such a way as to be maximally user-friendly to both the basic scientst and the clinician interested in this fascinating disease.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 404 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is intended to provide an overview and scholarly analysis of state-of-the-art developments within the field of environmental simulation research. Environmental simulation involves the presentation of scale model previews, full-scale mock-ups, and computer images of planned environments and activities taking place within them to designers and to prospective users of those settings. Environmental simulations are under taken for many purposes, including (1) the training of environmental de sign students and professionals, (2) the assessment of people's environ mental preferences, and (3) the incorporation of observers' assessments of simulated settings into the planning, design, and renovation of actual envi ronments to maximize the degree of fit between occupants' needs and the arrangement of their physical surroundings. Environmental simulation research has expanded rapidly during the past two decades as the result of increasing collaboration between behav ioral and social scientists, environmental designers, and professional plan ners. During this period, alternative conceptual and methodological ap proaches to environmental simulation have emerged, and numerous programs of simulation research have been initiated worldwide. To date, however, no attempt has been made to present a comprehensive review and assessment of these research developments and an analysis of their implications for design and public policy. Accordingly, the major objectives of this volume are to provide an overview of key conceptual and meth odological advances within the field of environmental simulation research and to place these diverse developments within a broader scientific and public policy context. 348 pp. Englisch.

Neuware -When I first proposed this book, one of the hopes was that it would be the stage upon which would be conducted a quiet, well reasoned discussion of the various techniques of stereotactic radio surgery. At that time, there was quite a bit of rancorous debate that tended to obscure the scientific and medical merits of each of the separate methods. At the present time, I am happy to report that the field of stereotactic radiosurgery is much less riven by such inappropriate posturing. The field has taken many steps towards maturity, both technically and medically. In the course of this mat uration process, there have been many grandiose plans and speeches made on behalf of stereotactic radiosurgery. Inevitably, the reality will not live up to the hype, but such is the natural course of devel opment in these sorts of matters. However, even though events may not match our hopes, we should keep in mind the words of Herbert Parker. Recognizing that new modalities for the treatment of cancer do not stand much chance of revolutionary success, nevertheless, he quite correctly pointed out that ' . . . with any type of radiatiQn, the margin between success and failure is small. If the chance of success is a little greater . . . thi~ might well be classed as a great advance. ' Mark H.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 316 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Handbook of Effective Psydwtherapy is the culmination of 15 years of personal interest in the area of psychotherapy outcome research. In my view, this is one of the most interesting and crucial areas in the field: it has relevance across disparate clinical disciplines and orientations; it provides a measure of how far the field has progressed in its efforts to improve the effectiveness of psychotherapeutic inter vention; and it provides an ongoing measure of how readily clinicians adapt to scientific indications in state-of-the-art care. Regrettably, as several of the chapters in this volume indicate, there is a vast chasm between what is known about the best available treatments and what is applied as the usual standard of care. On the most basic level there appears to be a significant number of clinicians who remain reluctant to acknowledge that scien tific study can add to their ability to aid the emotionally distressed. I hope that this handbook, with its many delineations of empirically supported treatments, will do something to remedy this state of affairs. 524 pp. Englisch.

This series of symposia was initiated in 1987 in light of the growing importance to eliminate particles from process gases and liquids. As pointed out in the Preface to antecedent volumes in this series that particles in process gases and liquids could cause significant yield losses in precision manufacturing and concomitantly there has been heightened interest in understanding the behavior of particles in gases and liquids and devising ways to eliminate, or at least reduce substantially, these particles. The concern about particles in gases and liquids has been there for qui.te some time in the microelectronics arena, but there are other areas also where particles are of significant concern, e.g. in operation theatres in hospitals, food and beverage industry, and pharmaceutical manufacturing. This symposium basically had the same objectives as its predecessors, but to provide an update on the R&D activity taking place in the arena of particle detection, characterization and control. The printed program comprised a total of 28 papers dealing with variegated aspects of particles in gases and liquids. There were brisk and lively discussions and the attendees offered many positive comments, which goes to show that it was a well-received and needed symposium. 308 pp. Englisch.

The heterojunction high-electron-mobility transistor (HEMT), invented in 1980, has become a key component for satellite broadcasting receiver systems, serving as the ultra-low-noise device at 12 GHz. Furthermore, the heterojunction bipolar transistor (HBT) has been considered as having the highest switching speed and cutoff frequency in the semiconductor device field. Initially most of these devices were used for analog high-frequency applications, but there is also a strong need to develop high-speed III-V digital devices for computer, telecom munication, and instrumentation systems, to replace silicon high-speed devices, because of the switching-speed and power-dissipation limitations of silicon. The potential high speed and low power dissipation of digital integrated circuits using GaAs MESFET, HEMT, HBT, and superconducting Josephson junction devices has evoked tremendous competition in the race to develop such technology. A technology review shows that Japanese research institutes and companies have taken the lead in the development of these devices, and some integrated circuits have already been applied to supercomputers in Japan. The activities of Japanese research institutes and companies in the III-V and superconducting device fields have been superior for three reasons. First, bulk crystal growth, epitaxial growth, process, and design technology were developed at the same time. 324 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Lead-based paint has become a national issue and will continue to be a hi- priority focus ofnational, state, and local agencies until there is no lead-based paint in the United States. Lead-based paint has become a tremendous health hazard for people and animals. Lead-based paint has been in widespread use throughout Europe and the United States. Lead has been known to be a health hazard since the time ofPliny the Elder (A. D. 23-79), but it was deemed that the advantages of lead in paint outweighed the health hazards. There has been a change in outlook, and in 1973 the U. S. Congress banned all lead paint from residential structures. A voluminous number of law suits have been initiated since, and continue to be litigated with the purpose of determining the parties responsible for the lead poisoning of children and others and to exact the indemnities. Lead-based paint is still authorized for use on bridges and nonresidential structures, and thousands of city, state, military, and federal government housing projects still contain lead-based paint. This paint must be removed if these dwellings are to be safe living quarters, especially for children. Aba- ment techniques continue to be evaluated; some have been used successfully. Lead-based paint abatement will continue into the next century, and it is hoped that this comprehensive volume will serve as a guide for those seriously interested in this important subject. 308 pp. Englisch.
