A highly necessary tool in a world where both feedback and non linearities abound. Similarly, all kinds of parts of mathematics serve as tools for other parts and for other sciences. Applying a simple rewriting rule to the quote on the right above one finds such statements as: 'One service topology has rendered mathematical physics . .'; 'One service logic has rendered com puter science . .'; 'One service category theory has rendered mathematics . .'. All arguably true. And all statements obtainable this way form part of the raison d'etre of this series.

Buch. Zustand: Neu. Neuware - Artificial Neural Networks have captured the interest of many researchers in the last five years. As with many young fields, neural network research has been largely empirical in nature, relyingstrongly on simulationstudies ofvarious network models. Empiricism is, of course, essential to any science… for it provides a body of observations allowing initial characterization of the field. Eventually, however, any maturing field must begin the process of validating empirically derived conjectures with rigorous mathematical models. It is in this way that science has always pro ceeded. It is in this way that science provides conclusions that can be used across a variety of applications. This monograph by Michael Lemmon provides just such a theoretical exploration of the role ofcompetition in Artificial Neural Networks. There is 'good news' and 'bad news' associated with theoretical research in neural networks. The bad news isthat such work usually requires the understanding of and bringing together of results from many seemingly disparate disciplines such as neurobiology, cognitive psychology, theory of differential equations, largc scale systems theory, computer science, and electrical engineering. The good news is that for those capable of making this synthesis, the rewards are rich as exemplified in this monograph.

Buch. Zustand: Neu. Neuware - The VHSIC Hardware Description Language (VHDL) provides a standard machine processable notation for describing hardware. VHDL is the result of a collaborative effort between IBM, Intermetrics, and Texas Instruments; sponsored by the Very High Speed Integrated Cir cuits (VHSIC) program office of the…Department of Defense, beginning in 1981. Today it is an IEEE standard (1076-1987), and several simulators and other automated support tools for it are available commercially. By providing a standard notation for describing hardware, especially in the early stages of the hardware design process, VHDL is expected to reduce both the time lag and the cost involved in building new systems and upgrading existing ones. VHDL is the result of an evolutionary approach to language devel opment starting with high level hardware description languages existing in 1981. It has a decidedly programming language flavor, resulting both from the orientation of hardware languages of that time, and from a ma jor requirement that VHDL use Ada constructs wherever appropriate. During the 1980's there has been an increasing current of research into high level specification languages for systems, particularly in the software area, and new methods of utilizing specifications in systems de velopment. This activity is worldwide and includes, for example, object oriented design, various rigorous development methods, mathematical verification, and synthesis from high level specifications. VAL (VHDL Annotation Language) is a simple further step in the evolution of hardware description languages in the direction of applying new methods that have developed since VHDL was designed.

There is no experimental evidence on such a future contingency, and yet we are not completely in the dark. There is a long history of expertise in the field; and there is a well-tried standard model by which experts' guesses can be translated into mathematical form.

Buch. Zustand: Neu. Neuware - This treatise had its origins in the authors' strong opinion that the discovery of new drugs, especially of innovative therapeutic agents, really does not happen as a spontaneous sequel to investiga tive research, no matter how penetrating such research may be. Rather, it seemed to us that the disco…very of innovative therapeutic agents was a very active process, existing in and of itself, and demanding full attention-it was not simply a passive, dependent by-process of investigative research. And yet, many researchers some close confreres of the authors, others more distant-believed otherwise. We felt that their view reflected unrealistic thinking and that reality probably lay closer to what Beyer' maintained: We are taught to believe that if we can understand a disease it should be easy enough to figure out, say, the molecular configuration of a definitive receptor mechanism somewhere along the line and to design a specific drug . . . . And so we start out to understand the disease but never get around to doing much about therapy. The authors very soon realized that there was essentially no quantitive information available on just where and how innovative therapeutic agents were discovered. There were only anecdotal accounts, and these were able to be selected and presented in ways that could be used to defend any point of view.

Buch. Zustand: Neu. Neuware - Gallium Arsenide technology has come of age. GaAs integrated circuits are available today as gate arrays with an operating speed in excess of one Gigabits per second. Special purpose GaAs circuits are used in optical fiber digital communications systems for the purpose of regeneration, multiplexing…and switching of the optical signals. As advances in fabrication and packaging techniques are made, the operat ing speed will further increase and the cost of production will reach a point where large scale application of GaAs circuits will be economical in these and other systems where speed is paramount. This book is written for students and engineers who wish to enter into this new field of electronics for the first time and who wish to embark on a serious study of the subject of GaAs circuit design. No prior knowledge of GaAs technology is assumed though some previous experience with MOS circuit design will be helpful. A good part of the book is devoted to circuit analysis, to the extent that is possible for non linear circuits. The circuit model of the GaAs transistor is derived from first principles and analytic formulas useful in predicting the approxi mate circuit performance are also derived. Computer simulation is used throughout the book to show the expected performance and to study the effects of parameter variations.

Buch. Zustand: Neu. Neuware - The purpose of these volumes is to provide a reference work for the methods of purifying many of the receptors we know about. This be comes increasingly important as full-length receptors are overexpressed in bacteria or in insect cell systems. A major problem for abundantly expressed proteins will…be their purification. In addition to purification protocols, many other details can be found concerning an individual receptor that may not be available in standard texts or monographs. No book of this type is available as a compendium of purification procedures. Receptor Purification provides protocols for the purification of a wide variety of receptors. These include receptors that bind: neurotransmit ters, polypeptide hormones, steroid hormones, and ligands for related members of the steroid supergene family and others, including receptors involved in bacterial motion. The text of this information is substantial, so as to require its publication in two volumes. Consequently, a division was made by grouping receptors by the nature of their ligands. Thus, in Volume One there are contributions on serotonin receptors, adrenergic receptors, the purification of GTP-binding proteins, opioid receptors, neurotensin receptor, luteinizing hormone receptor, human chorionic gonadotropin receptor, follicle stimulating hormone receptor, thyro tropin receptor, prolactin receptor, epidermal growth factor receptor, platelet derived growth factor receptor, colony stimulating factor recep tor, insulin-like growth factor receptors, insulin receptor, fibronectin receptor, interferon receptor, and the cholecystokinin receptor.

Buch. Zustand: Neu. Neuware - If one envisages neuroscience as a pyramid, with the more mole- lar disciplines forming the base and the more integrative d- ciplines positioned above, then neuropsychology clearly would be near the tip. Neuropsychology seeks to find order in the ultimate product of all neural systems, namely behavi…or, and to relate that product to its neural substrate. Relationships between brain and behavior are sought, but reductionistic explanations are eschewed. Attempting to 'explain' complex behaviors in terms of neuronal activity is no more satisfying than attempting to 'explain' artificial intelligence in terms of voltages within a computer's central pr- essing unit. If one is to comprehend the functioning of either the brain or the digital computer, one must know something about not only the structure and mechanics of the device, but also the prin- ples according to which components of the device are organized and the context in which the device is operating (e.g., environm- tal inputs and stored information).

Buch. Zustand: Neu. Neuware - The first version of this book, Packaging Materials and Containers was published in 1967 and was revised extensively ten years later under the title The Packaging Media. Some thirty or so authors were involved in producing the initial texts for these books, and I must acknowledge their material, muc…h of which is still valid. It is now thirteen years since The Packaging Media-high time to take stock and incorporate the considerable advances in materials, forms, techniques and machinery that have taken place. In 1977, wherever possible, we asked the original authors to carry out the revisions, but retirements and job changes have now eliminated over twenty of the original authors. We have therefore appointed an Editorial Board to advise on this more extensive revision, and I wish to thank them for their detailed and helpful assistance: Dr C. J. Mackson and Professor Y. Dagel for general comments and guidance on the overall plan and, in particular, the Introduction (chapter 1); Graham Gordon and Harri Mostyn for assistance with much of Part D on Distribution Packages, and Dennis Hine and Susan Selke for their work in respect of paperboard and plastics retail packaging, respectively. A major contribution was made by the seventh member of the Editorial Board, David Osborne, who advised in the area of glass.

Buch. Zustand: Neu. Neuware - Phenomenology was in large part the discovery of Edmund Husserl, whose Logical Investigations of 1900/01 are normally regarded as the work that launched the phenomenological movement. Yet Husserl's phenomenology, in particular in the form in which it is set out in this his most important contributio…n to philosophy, is itself part of an Austrian philosophical tradi tion inspired by Brentano and continued, in very different ways, by Meinong, Stumpf, Twardowski, Ehrenfels, Husserl - and Marty. Like Brentano and all his heirs Marty's philosophical interests were in the philosophy of mind, where this is taken to include or at least ground the philosophy of language, and analytic metaphysics. It is Marty's discussions of topics in these two areas that provide the contributions to this volume with their subject-matter. The papers by Roderick Chisholm, S. -Y. Kuroda, Barry Smith, Peter Simons, Rosaria Egidi, Karl Schuhmann, Elmar Holenstein, Edgar Morscher, Wolf gang Wenning and myself were presented at the 1984 conference on Anton Marty in Fribourg, Switzerland. Our host in Fribourg was Guido Kung, the conference was made possible by the Fritz Thyssen Stiftung. I should like to thank both for their help.

The encouraging response received from authors who have contributed the for…thcoming volumes and from the subscribers to the series has indicated the need for such a publication. Homa Motamen-Scobi London December 1987 Preface In 1990 both OPEC and the OECD will celebrate their thirtieth anntvers aries. OPEC was founded - rather unnoticed - by oil-producing countries still struggling to gain control over national petroleum resources. Future members were still under colonial rule. The foremost aim of the new organization - years before it was able to make metropolitan newspaper headlines - was stabilizing oil prices. Stability in those days meant prevent ing oil prices from falling in real terms. The OECD was formed by mostly mature industrial economies marking the normalization of the postwar international economy after years of reconstruction, strict trade regulations, etc. The aim of the new organization was to promote 'the highest sustainable growth and employment' in member countries. Incidentally, 1960 was also the year which gave birth to a more loosely defined block in the world community, namely the underdeveloped countries, qS the African colonial empires finally broke up. The two organizations became adversaries in the 1970s in the power struggle over the energy flows of the world.

Buch. Zustand: Neu. Neuware - This volume, SCIENCE OF SINTERING: NEW DIRECTIONS FOR MATERIALS PROCESSING AND MICROSTRUCTURAL CONTROL, contains the edited Proceedings of the Seventh World Round Table Conference on Sintering, held in Herceg-Novi, Yugoslavia, Aug. 28 - Sept. 1, 1989. It was organized by the International Institute…for the Science of Sintering (IISS), headquartered in Belgrade, Yugoslavia. Every fourth year since 1969, the Institute has organized such a Round Table Conference on Sintering; each has taken place at some selected location within Yugoslavia. A separate series of IISS Topical Sintering Symposia (Summer Schools) have also been held at four year intervals, but they have been offset by about two years, so they occur between the main Conferences. As a rule, the Topical Sintering Symposia have been devoted to more specific topics and they also take place in different countries. The aim of these Conferences and their related 'Summer Schools' has been to bring together scientists from all over the world who work in various fields of science and technology concerned with sintering and sintered materials. A total of seven IISS Conferences have been held over the period 1969-1989, and they have been supplemented by the four Topical Sintering Symposia held in Yugoslavia, Poland, India and Japan (in 1975, 1979, 1983 and 1987, respectively). This most recent five day Conference addressed the fundamental scientific background as well as the technological state-of-the-art pertinent to science of sintering and high technology sintered materials.

Buch. Zustand: Neu. Neuware - This work is concerned with Cystic Fibrosis (CF), the most common fatal genetic disease in the Caucasian population. The decade of the 1980s was one of spectacular progress in understanding the genetic and molecu lar basis of CF. The research breakthroughs of the decade began with the first fundamen…tal insights, published in 1981-1983, into the basic cellular pathophysiology of CF with demonstrations of altered ion transport in spe cialized exocrine epithelial tissues (1-3). Research progress shifted into a triumph of 'reverse genetics,' using restriction-fragment-Iength polymor phism DNA technology (4), with the localization of the CF gene to a region of chromosome 7 (5-7). Understanding, accelerated by an explOSion of in vitro methodologies for epithelial cell culture and transformation, allowed and physiological studies (8-11); these focused, controlled biochemical with increasing precision, on the molecular pathology of distal steps in the regulatory pathways for epithelial ion transport (12-19). Finally, the 'end of the beginning' occurred in late 1989 with one of the great achievements of molecular genetics, the isolation and cloning of the CF gene (20). As a result, we now have a CF gene product, the cystic fibrosis transmembrane regulator (CFfR), possessing predicted amino acid sequence, suggested tertiary structure, and possible transmembrane transport function (21). These amazing developments have set the stage for the next round of advances, which surely will include: 1.

Buch. Zustand: Neu. Neuware - Over the past decade, techniques have been developed and implemented to observe metabolism noninvasively in localized regions of intact, living experimental animals and humans through the use of magnetic resonance spectroscopy (MRS). At the same time, magnetic resonance imaging (MRI) techniques deve…loped in the 1970s and refined in this decade have been increasingly applied as a powerful clinical tool to probe human anatomy. Because of the unusual metabolic and physiologic characteristics of malignant tissues, oncology has been one of the primary focuses of the application of both MRS and MRI. Although considerable progress has been made in oncologic applications of magnetic resonance (MR), further research is needed to realize the full potential of MR in this area. Consequently, the 21st Annual Detroit Cancer Symposium entitled 'Magnetic Resonance in Experimental and Clin ical Oncology' was organized to provide a forum for researchers in the field to report the state of the art of MRS and MRI in oncol ogy, to discuss future goals for MRS and MRI in oncology, and to define the research needed to meet those goals. The major emphasis of the symposium was on MRS due to both the recent widespread availability of clinical MRS instrumentation and the extensive amount of animal MRS research performed over the past half decade.

Buch. Zustand: Neu. Neuware - The papersin this volume are as a resultofcontributions given at the NATO Advanced Study Institute heldat L1andinam Building, University CollegeofWales, Aberystwyth, 10 - 23 September 1989. The Institute considered the physical and chemical propertiesof a variety ofcolloidal systems ranging from sim…ple micellar solutions to concentrated colloidal dispersions. The purpose ofthe NATO Advanced Study Institute was to create a forum so that research scientists working in different areas concerned with colloid science could interact. The emphasL oft1'l. ;: contributions were on the interpretation ofthe different experimental and theoretical approach to give information on the structure, dynamics and equilibrium propertiesofthese systems. The application ofseveral different techniques in colloid science have been described; new developments and perspectives have been covered by several authors. The present volume reviews the current stale ofthe art in this area and it is hoped that it will be used as an incentive for further studies particularlywith reference to new areas ofresearch. In the organisation ofthe scientific programme for the NATO meeting we would like to acknowledge the assistance ofProfessors J. Lyklema, D. G. Hall and J. Holzwarth. We wish to thank Miss Mandy Rudd for all the secretarial assistance in setting up the meeting and for the invaluable assistance in preparing the manuscripts. In connection with the proceedings we would also like to thank Miss Sandra Fahy for assistance. The help of Paul Jones and Mrs G. Wyn-Jones during the meeting is also gratefully acknowledged.
