Taschenbuch. Condición: Neu. Neuware -This volume contains selected contributions from the XIth Meeting of the European Society for Stereotactic and Functional Neurosurgery held in September 1994 in Antalyaffurkey. Most of the papers deal with the many therapeutic and technical advancements made in this field of neurosurgery. The emergence of new stereotactic methodologies such as frameless stereotaxy and other forms of neuronavigation have become an indispensable tool for all types of neurosurgical operations. An increasing number of young neurosurgeons takes an interest in the neurosurgical approaches to the treatment of movement disorders, chronic pain and epilepsy. This is a clear sign ofthe growing awareness of the long neglected fact that these neurosurgical treatments can be offered to large patient populations. Neurotransplantation as a novel treatment of Parkinson's disease has paved the way for the application of this technology for other indications. The pioneering work performed by the late Edward Hitchcock is reviewed here. There is a renewed interest in pallidotomy for dealing with certain forms of Parkinson's disease and certain aspects of this operation are discussed in another paper. Progress in the neurosurgical treatment of pain is dealt with by contributions on refined techniques of percutaneous cordotomy, DREZ operations and critical evaluations of spinal cord stimulation. A novel approach is a report on the experiences of treating cancer pain by intraspinal implantation of chromaffin cells. Several contributions cover the important issues of novel techniques for the study of neural dysfunction, peroperative monitoring with PET, microrecording, magneto-encephalography and other techniques.

Taschenbuch. Condición: Neu. Neuware -The author's general aim has been to survey as wide a field of evidence as possible and this had involved excursions into subjects of which he has little first hand knowledge. This width of range also has necessitated a somewhat arbitrary selection of evidence and has prevented full discussion of any indi vidual problem. The author trusts that he has not misrepresented anyone's results or opinions, and if this has occurred, he can only plead in excuse the peculiar difficulty of giving a brief and yet accurate account of evidence of such a wide variety. The diagrams reproduced in the article have all been redrawn and in many cases the original figures or diagrams have been modified as, for instance, by recalculating dosage on the logarithmic scale. The original authors therefore have no direct responsibility for the diagrams in their present form. The author desires to thank Messrs Arnold and Co. for permitting the repro duction of Figs. 9 and 23 from similar figures which appeared in his book 'The Mode of Action of Drugs on Cells'; portions of other figures from this book also have been reproduced in modified form. The author also desires to thank Dr. J. M. ROBSON for help in correction of the proofs. Edinburgh, July, 1937. A. J. CLARK. Contents.

Taschenbuch. Condición: Neu. Neuware -Recent developments in various areas of chemistry have been decisively influenced by the principles of structure and mechanism and by the ideas of coordination chemistry, in particular by the donor-acceptor approach, A unified view of almost all kinds of molecular forces is provided by quantum mechanics, and for practical purposes have been classified according to model assumptions, namely, dispersion, polarization, electrostatic, and short-range forces. The latter are divided into two- and three-center covalent chemical bonds, metallic bonds, and exchange-repulsion forces. This approach allows statements of principle and systematic analysis. However, quantitative predictions on concrete large systems are virtually impossible, and there are no general rules that account for structural and chemical changes due to intermolecular interactions. Chemists are therefore left with qualitative descriptions in which the changes in electron densities are considered. Such models as the MO theory or the resonance concept unrealistically assume that the nuclei remain in fixed positions. Further difficulties are encountered in the attempted description on the 'nature' of the chemical bond, e.g., the forces involved. In order to avoid these difficulties an extension of the donor-acceptor concept, characterized by the comparison between equilibrium structures in different molecular environments, will be presented in this book. In this way, changes in the positions of the nuclei can be taken into account and the question of the nature of the molecular forces is no longer important.

Taschenbuch. Condición: Neu. Neuware -At the University of Rhode Island over 25% of engineering undergraduates simultaneously complete a second degree in German, French, Spanish, or Chinese. They furthermore spend an entire year abroad, one semester as exchange students at a partner university and six months as professional engineering interns at a cooperating company. With a close-to 100% placement rate, over 400 graduates, and numerous national awards, the URI International Engineering Program (IEP) is a proven path of preparation for young engineers in today's global workplace.The author of this volume, John Grandin, is an emeritus professor of German who developed and led the IEP for twenty-three years. In these pages, he provides a two-pronged approach to explain the origin and history of this program rooted in such an unusual merger of two traditionally distinct higher education disciplines. He looks first at himself to explain how and why he became an international educator and what led him to his lasting passion for the IEP. He then provides an historical overview of the program's origin and growth, including looks at the bumps and bruises and ups and downs along the way. Grandin hopes that this story will be of use and value to other educators determined to reform higher education and align it with the needs of the 21st Century.Table of Contents: How I became a Professor of German / My Unexpected Path to Engineering / Building a Network of Support / Sidetracked by a Stint in the Dean's Office / Reshaping the Language Mission / Struggling to Institutionalize / Partnering with Universities Abroad / Going into the Hotel and Restaurant Business / Taking the Lead Nationally / Building the Chinese IEP / Staying Involved after Retirement / The Broader Message for Higher Education / ConclusionsSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 92 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The creation of physical and material infrastructure is the cornerstone of human development; not surprisingly, engineers and designers are often motivated and inspired in their practice to improve the world around them, to make things better for others, and to apply their knowledge for the good of mankind. These aspirations often get translated into engineering and design curricula where students and faculty work on development related projects usually under the category of community or service learning. This book presents an overview of such an education and outreach program designed to empower stakeholders to improve their lives. The project described here was an international multi-institutional undertaking that included academic institutions, non-governmental organizations, and private firms. Within the academic setting, an interdisciplinary set of actors that included engineering and industrial design students and faculty worked on the project. We concretize our work by presenting a design case study that illustrates how different approaches can help guide the works of engineers and designers as they create global infrastructures and localized artifacts. We emphasize the importance of developing long term relationships with organizations on the ground in order to ensure appropriate design as well as successful transfer and long term use of designed artifacts. We discuss the life trajectories of the authors to provide a grounded perspective on what motivated us to undertake this work and shaped our approach with the intention to demonstrate that there are multiple paths toward this goal.Table of Contents: Introduction / Development of the Program: Personal Trajectories Meet Professional Opportunities / Intellectual Positioning of the Program: Sociomaterial Infrastructures and Capable and Convivial Design / Case Study: Quick Response (QR) Code Based Immunization Solution / Design for Development Course and Outreach Initiative / Conclusion: Lessons LearnedSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 116 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Declarative Networking is a programming methodology that enables developers to concisely specify network protocols and services, which are directly compiled to a dataflow framework that executes the specifications. Declarative networking proposes the use of a declarative query language for specifying and implementing network protocols, and employs a dataflow framework at runtime for communication and maintenance of network state. The primary goal of declarative networking is to greatly simplify the process of specifying, implementing, deploying and evolving a network design. In addition, declarative networking serves as an important step towards an extensible, evolvable network architecture that can support flexible, secure and efficient deployment of new network protocols. This book provides an introduction to basic issues in declarative networking, including language design, optimization and dataflow execution. The methodology behind declarative programming of networks is presented,including roots in Datalog, extensions for networked environments, and the semantics of long-running queries over network state. The book focuses on a representative declarative networking language called Network Datalog (NDlog), which is based on extensions to the Datalog recursive query language. An overview of declarative network protocols written in NDlog is provided, and its usage is illustrated using examples from routing protocols and overlay networks. This book also describes the implementation of a declarative networking engine and NDlog execution strategies that provide eventual consistency semantics with significant flexibility in execution. Two representative declarative networking systems (P2 and its successor RapidNet) are presented. Finally, the book highlights recent advances in declarative networking, and new declarative approaches to related problems.

Taschenbuch. Condición: Neu. Neuware -Content-based image retrieval (CBIR) is the process of retrieval of images from a database that are similar to a query image, using measures derived from the images themselves, rather than relying on accompanying text or annotation. To achieve CBIR, the contents of the images need to be characterized by quantitative features; the features of the query image are compared with the features of each image in the database and images having high similarity with respect to the query image are retrieved and displayed. CBIR of medical images is a useful tool and could provide radiologists with assistance in the form of a display of relevant past cases. One of the challenging aspects of CBIR is to extract features from the images to represent their visual, diagnostic, or application-specific information content. In this book, methods are presented for preprocessing, segmentation, landmarking, feature extraction, and indexing of mammograms for CBIR. The preprocessing steps include anisotropic diffusion and the Wiener filter to remove noise and perform image enhancement. Techniques are described for segmentation of the breast and fibroglandular disk, including maximum entropy, a moment-preserving method, and Otsu's method. Image processing techniques are described for automatic detection of the nipple and the edge of the pectoral muscle via analysis in the Radon domain. By using the nipple and the pectoral muscle as landmarks, mammograms are divided into their internal, external, upper, and lower parts for further analysis. Methods are presented for feature extraction using texture analysis, shape analysis, granulometric analysis, moments, and statistical measures. The CBIR system presented provides options for retrieval using the Kohonen self-organizing map and the k-nearest-neighbor method. Methods are described for inclusion of expert knowledge to reduce the semantic gap in CBIR, including the query point movement method for relevance feedback (RFb). Analysis of performanceis described in terms of precision, recall, and relevance-weighted precision of retrieval. Results of application to a clinical database of mammograms are presented, including the input of expert radiologists into the CBIR and RFb processes. Models are presented for integration of CBIR and computer-aided diagnosis (CAD) with a picture archival and communication system (PACS) for efficient workflow in a hospital.

Taschenbuch. Condición: Neu. Neuware -As networks of video cameras are installed in many applications like security and surveillance, environmental monitoring, disaster response, and assisted living facilities, among others, image understanding in camera networks is becoming an important area of research and technology development. There are many challenges that need to be addressed in the process. Some of them are listed below: - Traditional computer vision challenges in tracking and recognition, robustness to pose, illumination, occlusion, clutter, recognition of objects, and activities; - Aggregating local information for wide area scene understanding, like obtaining stable, long-term tracks of objects; - Positioning of the cameras and dynamic control of pan-tilt-zoom (PTZ) cameras for optimal sensing; - Distributed processing and scene analysis algorithms; - Resource constraints imposed by different applications like security and surveillance, environmental monitoring, disaster response, assisted living facilities, etc. In this book, we focus on the basic research problems in camera networks, review the current state-of-the-art and present a detailed description of some of the recently developed methodologies. The major underlying theme in all the work presented is to take a network-centric view whereby the overall decisions are made at the network level. This is sometimes achieved by accumulating all the data at a central server, while at other times by exchanging decisions made by individual cameras based on their locally sensed data. Chapter One starts with an overview of the problems in camera networks and the major research directions. Some of the currently available experimental testbeds are also discussed here. One of the fundamental tasks in the analysis of dynamic scenes is to track objects. Since camera networks cover a large area, the systems need to be able to track over such wide areas where there could be both overlapping and non-overlapping fields of view of the cameras, as addressedin Chapter Two: Distributed processing is another challenge in camera networks and recent methods have shown how to do tracking, pose estimation and calibration in a distributed environment. Consensus algorithms that enable these tasks are described in Chapter Three. Chapter Four summarizes a few approaches on object and activity recognition in both distributed and centralized camera network environments. All these methods have focused primarily on the analysis side given that images are being obtained by the cameras. Efficient utilization of such networks often calls for active sensing, whereby the acquisition and analysis phases are closely linked. We discuss this issue in detail in Chapter Five and show how collaborative and opportunistic sensing in a camera network can be achieved. Finally, Chapter Six concludes the book by highlighting the major directions for future research.

Taschenbuch. Condición: Neu. Neuware -This book introduces the theory, algorithms, and implementation techniques for efficient decoding in speech recognition mainly focusing on the Weighted Finite-State Transducer (WFST) approach. The decoding process for speech recognition is viewed as a search problem whose goal is to find a sequence of words that best matches an input speech signal. Since this process becomes computationally more expensive as the system vocabulary size increases, research has long been devoted to reducing the computational cost. Recently, the WFST approach has become an important state-of-the-art speech recognition technology, because it offers improved decoding speed with fewer recognition errors compared with conventional methods. However, it is not easy to understand all the algorithms used in this framework, and they are still in a black box for many people. In this book, we review the WFST approach and aim to provide comprehensive interpretations of WFST operations and decoding algorithms to help anyone who wants to understand, develop, and study WFST-based speech recognizers. We also mention recent advances in this framework and its applications to spoken language processing.

Taschenbuch. Condición: Neu. Neuware -At first sight, finitely generated abelian groups and canonical forms of matrices appear to have little in common. However, reduction to Smith normal form, named after its originator H.J.S.Smith in 1861, is a matrix version of the Euclidean algorithm and is exactly what the theory requires in both cases. Starting with matrices over the integers, Part1 of this book provides a measured introduction to such groups: two finitely generated abelian groups are isomorphic if and only if their invariant factor sequences are identical. The analogous theory of matrix similarity over a field is then developed in Part2 starting with matrices having polynomial entries: two matrices over a field are similar if and only if their rational canonical forms are equal. Under certain conditions each matrix is similar to a diagonal or nearly diagonal matrix, namely its Jordan form.The reader is assumed to be familiar with the elementary properties of rings and fields. Also a knowledge of abstract linear algebra including vector spaces, linear mappings, matrices, bases and dimension is essential, although much of the theory is covered in the text but from a more general standpoint: the role of vector spaces is widened to modules over commutative rings.Based on a lecture course taught by the author for nearly thirty years, the book emphasises algorithmic techniques and features numerous worked examples and exercises with solutions. The early chapters form an ideal second course in algebra for second and third year undergraduates. The later chapters, which cover closely related topics, e.g. field extensions, endomorphism rings, automorphism groups, and variants of the canonical forms, will appeal to more advanced students. The book is a bridge between linear and abstract algebra.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 396 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Information collected by satellites recently sent by the USA, the European Space Agency, Japan, Germany, the United Kingdom, and Russia to monitor the Sun has changed our knowledge and understanding of the Sun, particularly its effect on Earth. This book presents these findings in a way that will be welcomed by amateur astronomers, students, educators and anyone interested in the Sun. Enhanced by many colour photographs, the book combines newly acquired scientific understanding with detailed descriptions of features visible on the Sun¿s surface and in its atmosphere.In the past, observing the Sun has been left to academics with specialised instruments, since solar observation has been unsafe because of the risk of eye damage. This book explains how amateur astronomers can safely observe the various solar phenomena using special hydrogen-alpha telescopes that are not too expensive. Amateurs can now make a positive contribution to science by monitoring the Sun as professionals do.Amateurs can also access the solar images taken by satellites via the internet. This book helps readers interpret and understand what these images are showing about the Sun, including the latest 3D images. Solar observers will enjoy comparing their own solar telescope observations with those produced by space probes such as SDO, SOHO, Hinode and STEREO, and further enjoy learning about transits, eclipses, and space weather and how the Sun compares to other stars in the universe.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 264 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -This volume presents a mathematical development of a recent approach to the modeling and simulation of turbulent flows based on methods for the approximate solution of inverse problems. The resulting Approximate Deconvolution Models or ADMs have some advantages over more commonly used turbulence models ¿ as well as some disadvantages. Our goal in this book is to provide a clear and complete mathematical development of ADMs, while pointing out the difficulties that remain. In order to do so, we present the analytical theory of ADMs, along with its connections, motivations and complements in the phenomenology of and algorithms for ADMs.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 196 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -A quorum system is a collection of subsets of nodes, called quorums, with the property that each pair of quorums have a non-empty intersection. Quorum systems are the key mathematical abstraction for ensuring consistency in fault-tolerant and highly available distributed computing. Critical for many applications since the early days of distributed computing, quorum systems have evolved from simple majorities of a set of processes to complex hierarchical collections of sets, tailored for general adversarial structures. The initial non-empty intersection property has been refined many times to account for, e.g., stronger (Byzantine) adversarial model, latency considerations or better availability. This monograph is an overview of the evolution and refinement of quorum systems, with emphasis on their role in two fundamental applications: distributed read/write storage and consensus. Table of Contents: Introduction / Preliminaries / Classical Quorum Systems / Classical Quorum-Based Emulations / Byzantine Quorum Systems / Latency-efficient Quorum Systems / Probabilistic Quorum SystemsSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 148 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -NS-2 is an open-source discrete event network simulator which is widely used by both the research community as well as by the people involved in the standardization protocols of IETF. The goal of this book is twofold: on one hand to learn how to use the NS-2 simulator, and on the other hand, to become acquainted with and to understand the operation of some of the simulated objects using NS-2 simulations. The book is intended to help students, engineers or researchers who need not have much background in programming or who want to learn through simple examples how to analyse some simulated objects using NS-2. Simulations may differ from each other in many aspects: the applications, topologies, parameters of network objects (links, nodes) and protocols used, etc. The first chapter is a general introduction to the book, where the importance of NS-2 as a tool for a good comprehension of networks and protocols is stated. In the next chapters we present special topics as TCP, RED, etc., using NS-2 as a tool for better understanding the protocols. We provide in the appendices a review of Random Variables and Confidence Intervals, as well as a first sketch for using the new NS-3 simulator.

Taschenbuch. Condición: Neu. Neuware -Compiling for parallelism is a longstanding topic of compiler research. This book describes the fundamental principles of compiling 'regular' numerical programs for parallelism. We begin with an explanation of analyses that allow a compiler to understand the interaction of data reads and writes in different statements and loop iterations during program execution. These analyses include dependence analysis, use-def analysis and pointer analysis. Next, we describe how the results of these analyses are used to enable transformations that make loops more amenable to parallelization, and discuss transformations that expose parallelism to target shared memory multicore and vector processors. We then discuss some problems that arise when parallelizing programs for execution on distributed memory machines. Finally, we conclude with an overview of solving Diophantine equations and suggestions for further readings in the topics of this book to enable the interested reader to delve deeper into the field. Table of Contents: Introduction and overview / Dependence analysis, dependence graphs and alias analysis / Program parallelization / Transformations to modify and eliminate dependences / Transformation of iterative and recursive constructs / Compiling for distributed memory machines / Solving Diophantine equations / A guide to further readingSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 172 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -There are 'voids' obscuring all kinds of objects in the cosmos.Voids may be withinan object, or betweenan object and us. Dark Nebulae, Dark Lanes, and Dust Lanes looks out into the deep sky at those apparent darkregions in space, which are among the most compelling telescopic destinations for amateur observers.One famous example is Barnard's dark nebulae - those striking dark clouds set against the background of stars in the Milky Way. But there are countless other less well knownexamples.These dark regions are often ignored altogether or commented upon onlybriefly in astronomy books, and it is all too easy to overlook the treasure trove they offer the observer.Dark Nebulae, Dark Lanes, and DustLanes is a great source of practical information for observers.Such voids may be successfully observed using conventional observing methods, but they are often far better seen with technologies such as light-pollution filters, CCD video cameras, and image intensifiers. This book explains the optimal ways to observe each object in detail.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 256 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -A FEW DAYS after Smetana's body had been laid to rest in the Vysehrad Cemetery, Prague, Franz Liszt sent word to Karel Navrlitil: 'In haste I write to tell you that the death of Smetana has deeply affected me. He was indeed a genius!' Ironically, with his death Smetana was proclaimed the founder of modern Czech music, but only a few years before he had been spurned, labelled 'Wagnerian' and accused of impeding the way of musical progress. Like Verdi, Smetana was a confirmed patriot. Dramatic music was his platform and his greatest ambition was to see the Prague National Theatre become the permanent home of Czech opera. This he witnessed, but not without making countless enemies and spending years of bitterness in arduous struggle. Smetana's life was one long struggle and sadly he never lived to reap the rewards of his efforts. He developed late. Like Schumann, his early works were almost exclusively for the piano: like Dostoevsky, his first important essay appeared only in middle life. His was relatively small. Few of his. scores found their way into print and, output apart from The Bartered Bride and The Kiss, little of his music was performed with any regularity during his life. After ten busy years, during which he wrote five operas and worked as Musical Director of the Prague Provisional Theatre, he was halted by deafness. There followed a further ten years in which illness and mental disorder made composition increasingly difficult.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 524 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Wireless sensor network (WSN) is an ad-hoc network technology comprising even thousands of autonomic and self-organizing nodes that combine environmental sensing, data processing, and wireless networking. The applications for sensor networks range from home and industrial environments to military uses. Unlike the traditional computer networks, a WSN is application-oriented and deployed for a specific task. WSNs are data centric, which means that messages are not send to individual nodes but to geographical locations or regions based on the data content. A WSN node is typically battery powered and characterized by extremely small size and low cost.As a result, the processing power, memory, and energy resources of an individual sensor node are limited. However, the feasibility of a WSN lies on the collaboration between the nodes. A reference WSN node comprises a Micro-Controller Unit (MCU) having few Million Instructions Per Second (MIPS) processing speed, tens of kilobytes program memory, few kilobytes data memory. In addition, the node contains a short-range radio, and a set of sensors. Supply power is typically obtained with small batteries. Assuming a target lifetime of one year using AA-size batteries, the available power budget is around 1 mW.This book covers the low-power WSNs services ranging from hardware platforms and communication protocols to network deployment, and sensor data collection and actuation. The implications of resource constraints and expected performance in terms of throughput, reliability and latency are explained. As a case study, this book presents experiments with low-energy TUTWSN technology to illustrate the possibilities and limitations of WSN applications.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 100 pp. Englisch.

Buch. Condición: Neu. Neuware -Arrangements of curves constitute fundamental structures that have been intensively studied in computational geometry. Arrangements have numerous applications in a wide range of areas ¿ examples include geographic information systems, robot motion planning, statistics, computer-assisted surgery and molecular biology. Implementing robust algorithms for arrangements is a notoriously difficult task, and the CGAL arrangements package is the first robust, comprehensive, generic and efficient implementation of data structures and algorithms for arrangements of curves.This book is about how to use CGAL two-dimensional arrangements to solve problems. The authors first demonstrate the features of the arrangement package and related packages using small example programs. They then describe applications, i.e., complete standalone programs written on top of CGAL arrangements used to solve meaningful problems ¿ for example, finding the minimum-area triangle defined by a set of points, planning the motion of a polygon translating among polygons in the plane, computing the offset polygon, finding the largest common point sets under approximate congruence, constructing the farthest-point Voronoi diagram, coordinating the motion of two discs moving among obstacles in the plane, and performing Boolean operations on curved polygons.The book contains comprehensive explanations of the solution programs, many illustrations, and detailed notes on further reading, and it is supported by a website that contains downloadable software and exercises. It will be suitable for graduate students and researchers involved in applied research in computational geometry, and for professionals who require worked-out solutions to real-life geometric problems. It is assumed that the reader is familiar with the C++ programming-language and with the basics of the generic-programming paradigm.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 316 pp. Englisch.

Neuware -The study of neurotransmitters in the human brain has expanded spectacularly in recent years with the application of techniques from immunology and molecular biology. These techniques are now being used successfully to help decipher the chemical architecture of the human nervous system. The results of these studies are of great importance for the understanding and treatment of neurological and psychiatric disorders such as Alzheimer's, Parkinson's and Huntington's diseases, as well as depression and schizophrenia. Professor Istvan Tork was a pioneer in the chemical anatomy of the brain and carried out important studies on the neuroanatomy and distribution of neuropeptides and monoarnines in the brain; some of his best known work dealt with the dual innervation of the cortex by neurons containing serotonin. Istvan Tork died on November 21, 1992, after a long struggle with a temporal lobe glioma, leaving a profound legacy of friendship and scholarly work 1. It was decided by the editors of this volume to commemorate his work and the mentors hip he gave to his many students by convening a symposium on neurotransmitters in the human brain. The symposium was held at the University of New South Wales on February 5, 1994, and was attended by over one hundred participants, including many of Professor Tork's colleagues and students. The papers from this symposium are presented in this volume to stand as a tribute to the breadth and quality of his work and to the energy and achievement of his students.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 256 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -I. Introduction Of the ever increasing number of viruses known to affect man and higher animals, the virus of lymphocytic choriomeningitis (LCM) was one of the first to be discovered. Indeed, this virus has been known and maintained in the laboratory by passages in a relatively simple host, the mouse, for 35 years. Yet our knowl edge of its properties is still scanty when compared with the wealth of informa tion available for other viruses, some of which have come to our attention much more recently. There are at least four reasons which may help to explain this seeming paradox. (1) The early belief that the LCM virus was the frequent cause of human diseases had soon to be abandoned; infections of man with this virus are rare. (2) By way of contrast, laboratory infections are not uncommon and they frequently run severe and even fatal courses. (3) Until recently, the only means of titrating the virus was by mouse inoculation, a method in which accuracy and economy are poorly correlated. (4) The virus is of unusual lability, being quickly inactivated under conditions which leave other viruses intact. Thus, when balancing medical and theoretical importance against personal hazard and tech nical difficulties, the result was quite unfavorable, and lack of interest was really not surprising. In the last few years, however, the situation has gradually changed and an increasing number of workers have turned their attention to this virus.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 184 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Mechanism of charge transport in organic solids has been an issue of intensive interests and debates for over 50 years, not only because of the applications in printing electronics, but also because of the great challenges in understanding the electronic processes in complex systems. With the fast developments of both electronic structure theory and the computational technology, the dream of predicting the charge mobility is now gradually becoming a reality.Thisvolume describes recent progresses in Prof. Shuai¿s group in developing computational tools to assess the intrinsic carrier mobility for organic and carbon materials at the first-principles level. According to the electron-phonon coupling strength, the charge transport mechanismis classified into three different categories, namely, the localized hopping model, the extended band model, and the polaron model. For each of them, a corresponding theoretical approach is developed and implemented into typical examples.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 100 pp. Englisch.
