Buch. Condizione: Neu. Neuware - I have purposely limited myself to a rather brief statement in this introduc tion, in order that the summing up be not misrepresented for the discursive development of the whole. There is something more than mildly dangerous in setting oneself a series of goals in an introduction only to find them happily attained in the conclusion, as if getting from the beginning to the end was simply a question of transition. Of course, the destination of a speculative presentation includes the process of development in such a way that the end is always implicitly the beginning: each configuration simply forms a deter minate moment within the on-going manifestation of the 'absolute'. It is around Hegel's concept of the absolute, how it is known and how it presents itself, which the bulk of our discussion turns. We may say tentatively that the absolute speaks. This speaking is the manifestation of the absolute itself, not a dissimulation or mere appearance, and consequently can be known and known most perfectly in language. In Hegel's system, this speak ing or discourse has exhausted itself and is complete, but in what manner this 'close' is achieved remains the question which disturbs and provokes our own speech in what is to come.

Buch. Condizione: Neu. Neuware - Breast cancer, being a disease with very high prevalence in the female population, has permanently attracted the attention of biologists, biochemists, pathologists, surgeons, and oncologists. In the U.S. alone approximately 120,000 new cases are diagnosed and 37,000 deaths a year are recorded as an outcome. Early diagnosis, clear cut prognosis and the hope of new therapeutic approaches has spurred the enthusiasm of researchers, who with the advent of newer methodologies, tried to employ it in different approaches to the breast cancer patient. In spite of the efforts devoted towards the creation of new approaches, reagents and procedures taking advantage of special characteristics of the breast tissue were slow to come. In general, most diagnostic and prognostic techniques were those shared and applied to other carcinomas. In the early seventies we discovered the first sets of antigens associated with breast epithelial tissue both in the mouse and the human. The recognition of such group of molecules, present in the milk fat globule membrane, gave impetus to several studies in these areas. These mammary cell surface antigens proved useful in several diagnostic approaches such as radioimaging, histochemical and serum assay procedures. However, the apparently inherent limitations of polyclonal antibodies reduced the impact of these novel approaches.

Buch. Condizione: Neu. Neuware - This volume represents a part of the scientific proceedings of the Sixth Annual Meeting of the American Section of the International Society for Heart Research that was held in Oklahoma City from September 13-15, 1984. The chapters have been grouped according to the content of invited symposia on cardiovascular topics ranging from electrophysiology, autonomic control of the circulation, aging of the myocardium, mechanisms of cardiovascular injury, cultured heart cell studies, etc. Abstracts of all the papers presented at this meeting are included in Volume 16 (Supp. 1) of the Journal of Molecular and Cellular Cardiology. Since our understanding of the pathobiology of cardiovascular injury requires integrating knowledge from both basic and clinical sciences, the information presented in this volume extends from fundamental biochemical processes to pharmacological agents required to treat complex cardiac arrhythmias. At the molecular level, the structural lipids of the sarcolemma may be altered during myocardial ischemia; the role of free radicals in this process is one emerging area of active study. At the subcellular level, plasma membranes provide the anatomical basis for maintenance of optimal potentials of excitable cells; the anatomy and physiology of the sarcolemma ultimately determines the response to drugs and metabolic perturbants. At the cellular level, much progress has been made in our understanding of cultured and adult myocytes during ischemia and hypoxia; in particular, the electrophysiology of these model systems is well understood and several chapters address this approach.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Recently, there has been a lot of interest in provably 'good' pseudo-random number generators [lo, 4, 14, 31. These cryptographically secure generators are 'good' in the sense that they pass all probabilistic polynomial time statistical tests. However, despite these nice properties, the secure generators known so far suffer from the han- cap of being inefiicient; the most efiicient of these take n2 steps (one modular multip- cation, n being the length of the seed) to generate one bit. Pseudc-random number g- erators that are currently used in practice output n bits per multiplication (n2 steps). An important open problem was to output even two bits on each multiplication in a cryptographically secure way. This problem was stated by Blum, Blum & Shub [3] in the context of their z2 mod N generator. They further ask: how many bits can be o- put per multiplication, maintaining cryptographic security In this paper we state a simple condition, the XOR-Condition and show that any generator satisfying this condition can output logn bits on each multiplication. We show that the XOR-Condition is satisfied by the lop least significant bits of the z2-mod N generator. The security of the z2 mod N generator was based on Quadratic Residu- ity [3]. This generator is an example of a Trapdoor Generator [13], and its trapdoor properties have been used in protocol design. We strengthen the security of this gene- tor by proving it as hard as factoring. 508 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The literature on systems seems to have been growing almost expo nentially during the last decade and one may question whether there is need for another book. In the author's view, most of the literature on 'systems' is either technical in mathematical sense or technical ifF engineering sense (with technical words such as noise, filtering etc. ) and not easily accessible to researchers is other fields, in particular not to economists, econometricians and quantitative researchers in so cial sciences. This is unfortunate, because achievements in the rather 'young' science of system theory and system engineering are of impor tance for modelling, estimation and regulation (control) problems in other branches of science. State space mode~iing; the concept of ob servability and controllability; the mathematical formulations of sta bility; the so-called canonical forms; prediction error e~timation; optimal control and Kalman filtering are some examples of results of system theory and system engineering which proved to be successful in practice. A brief summary of system theoretical concepts is given in Chapter II where an attempt has been made to translate the concepts in to the more 'familiar' language used in econometrics and social sciences by means of examples. By interrelating concepts and results from system theory with those from econometrics and social sciences, the author has attempted to narrow the gap between the more technical sciences such as engi neering and social sciences and econometrics, and to contribute to either side. 200 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Aggregation processes are studied within a number of different fields--c- loid chemistry, atmospheric physics, astrophysics, polymer science, and biology, to name only a few. Aggregation pro ces ses involve monomer units (e. g. , biological cells, liquid or colloidal droplets, latex beads, molecules, or even stars) that join together to form polymers or aggregates. A quantitative theory of aggre- tion was first formulated in 1916 by Smoluchowski who proposed that the time e- lution of the aggregate size distribution is governed by the infinite system of differential equations: (1) K . . c. c. - c k = 1, 2, . . . k 1. J 1. J L ~ i+j=k j=l where c is the concentration of k-mers, and aggregates are assumed to form by ir k reversible condensation reactions [i-mer + j-mer -+ (i+j)-mer]. When the kernel K . . can be represented by A + B(i+j) + Cij, with A, B, and C constant; and the in- 1. J itial condition is chosen to correspond to a monodisperse solution (i. e. , c (0) = 1 0, k 1), then the Smoluchowski equation can be co' a constant; and ck(O) solved exactly (Trubnikov, 1971; Drake, 1972; Ernst, Hendriks, and Ziff, 1982; Dongen and Ernst, 1983; Spouge, 1983; Ziff, 1984). For arbitrary K , the solution ij is not known and in some ca ses may not even exist. 136 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This treatment of molecular and atomic physics is primarily meant as a textbook. It is intended for both chemists and physicists. It can be read without much knowledge of quantum mechanics or mathematics, since all such details are explained-. It has developed through a series of lectures at the Royal Institute of Technology. The content is to about 50 % theoretical and to 50 % experimental. The reason why the authors, who are experimentalists, went into theory is the following. When we during the beginning of the 1970's measured photo electron spectra of organic molecules, it appeared to be impossible to understand them by use of available theoretical calculations. To handle hydrocarbons we ( together with C. Fridh ) constructed in 1972 a purely empirical procedure, SPINDO [1] which has proved to be useful, but the extension to molecules with hetero atoms appeared to be difficult. One of us ( L.A.) proposed then another purely ~~E!E!~~! EE2~~~~E~ ( Hydrogenic Atoms in Molecules, HAM/1, unpublished), in which the Fock matrix elements f5.y were parametrized using Slater's shielding concept. The self-repulsion was compensated by a term '-1'. The ~~2~~_~ff2E~, HAM/2 [2] , started from the total energy E:. of the molecule. The atomic parts of L used the Slater shielding constants, and the bond parts of E. were taken from SPINDO. The Fock matrix elements Fpv were then obtained from E in a conventional way. 304 pp. Englisch.

It is about what can be done with it right now on the farm. It is about today's technology, allowing decisions to be made about what to do with straw this year in order to minimize costs, minimize management problems and maximize yields and profits. It can be read cover to cover, chapter by chapter or dipped into as a reference book. Whichever way, this manual is aimed at helping the farmer to understand the technology and do the job that has to be done - profitably. Action Plans which summarize the relevant data and ease decision-making appear at the end of each chapter. The final part is a Decision Planner which will help with tackling the job in hand, on the day. Acknowledgments Grateful thanks are given to many individuals and organizations for their assistance, support and provision of information. Special acknowledgment is made to the fine work done by ADAS and their staff who made efforts to provide a great deal of up to date data for this publication. Thanks for assistance are also given to leI Plant Protection Division and to John Deere who, through their annual Award to agricultural writers, sparked this project off by giving the award to the author in 1982. 224 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -I have been working on this book since leaving Russia in April of 1972. It was my wish to write this book in English, and there were what seemed to me to be serious reasons for doing so. In recent years there has appeared a wealth of literature, in Russian, about Russia. As a rule, this literature has been published outside the USSR by authors who still live in the Soviet Union or who have only recently left it. A fair amount of important literature is being translated into English, but I believe it will be read main ly by specialists in Russian studies, or by those who have a great interest in the subject already. The majority of Russian authors write, of course, for the Russian reader or for an imagined Western public. It is my feeling that Russian authors have serious difficulties in understanding the men tality of Westerners, and that there still exists a gap between the visions of Russians and non-Russians. I have made my humble attempt to bridge ~his gap and I will be happy if I am even partly successful. The Russian world is indeed fascinating. Many people who visit Russia for a few days or weeks find it a country full of historical charm, fantastic architecture and infinite mystery. For many inside the country, especial ly for those in conflict with the Soviet authorities. 272 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is the first outcome of our effort in ASIAN LINK PROJECT to construct the econometric models of Asian developing countries and analyze their inter-dependence with major trading partners, the United States and Japan. The model we present here is called Asian Link System. The countries in this system include Korea, Taiwan, Hong Kong, China, the Philippines, Thailand, Malaysia, Singapore, Indonesia, Japan and the United States. They are covered by national models. The rest of the world is divided into several regions and treated by simple proto-type models. The main characteristics of Asian Link System are to deal with the inter-dependent relations between Asian developing countries on the one hand and Japan and United States on the other hand. Here are presented these national models and the Asian Link System with the underlying statistical data, so that any econometrician can re-estimate our models and check the results of our research work. Nowadays most articles and books in econometrics report only the final results or conclusions of research so that no other econometrician can re-calculate or re examine the findings. This is very serious in the empirical research, because as theorists may make mistakes, positive economists do commit errors or miss some possible considerations. Unless statiscal data are offered, other econometricians cannot make suggestions or improve the models. This is the main reason why empirical research in econometrics or applied econometrics are not making substantial progress in recent years. 352 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is about the regeneration of plants from seed under field conditions. It attempts to give a reasonably balanced overview of the many aspects of this broad topic. The first chapter introduces some general ideas about reproduction in plants. Subsequent chapters deal with the early stages in the life of a plant, from ovule to established seedling, in a more or less chronological order. The final chapter shows how the data on regeneration requirements of different species can be used to explain a number of important characteristics of whole plant communities. The study of the ecological aspects of reproduction by seed touches on a range of issues of current interest in biology. A discussion of seed size and number involves a consideration of the concepts of resource allocation, life cycles and strategies. The in teractions between plants and animals seen in pollination, seed dispersal and predation provide excellent material for the study of coevolution. Investigations on regeneration from seed have greatly our understanding of the causes and maintenance of species added to diversity. The reader will find that virtually all the experiments and field observations described in this book are conceptually very simple. Many of them merely required numerous careful measurements. 160 pp. Englisch.

J 1. J L ~ i+j=k j=l where c is the concentration of k-mers, and aggregates are assumed to form by ir k reversible condensation reactions [i-mer + j-mer -+ (i+j)-mer]. When the kernel K . . can be represented by A + B(i+j) + Cij, with A, B, and C constant; and the in- 1. J itial condition is chosen to correspond to a monodisperse solution (i. e. , c (0) = 1 0, k > 1), then the Smoluchowski equation can be co' a constant; and ck(O) solved exactly (Trubnikov, 1971; Drake, 1972; Ernst, Hendriks, and Ziff, 1982; Dongen and Ernst, 1983; Spouge, 1983; Ziff, 1984). For arbitrary K , the solution ij is not known and in some ca ses may not even exist.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 136 pp. Englisch.

Neuware -Recently, there has been a lot of interest in provably 'good' pseudo-random number generators [lo, 4, 14, 31. These cryptographically secure generators are 'good' in the sense that they pass all probabilistic polynomial time statistical tests. However, despite these nice properties, the secure generators known so far suffer from the han- cap of being inefiicient; the most efiicient of these take n2 steps (one modular multip- cation, n being the length of the seed) to generate one bit. Pseudc-random number g- erators that are currently used in practice output n bits per multiplication (n2 steps). An important open problem was to output even two bits on each multiplication in a cryptographically secure way. This problem was stated by Blum, Blum & Shub [3] in the context of their z2 mod N generator. They further ask: how many bits can be o- put per multiplication, maintaining cryptographic security In this paper we state a simple condition, the XOR-Condition and show that any generator satisfying this condition can output logn bits on each multiplication. We show that the XOR-Condition is satisfied by the lop least significant bits of the z2-mod N generator. The security of the z2 mod N generator was based on Quadratic Residu- ity [3]. This generator is an example of a Trapdoor Generator [13], and its trapdoor properties have been used in protocol design. We strengthen the security of this gene- tor by proving it as hard as factoring.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 508 pp. Englisch.

It is intended for both chemists and physicists. It can be read without much knowledge of quantum mechanics or mathematics, since all such details are explained-. It has developed through a series of lectures at the Royal Institute of Technology. The content is to about 50 % theoretical and to 50 % experimental. The reason why the authors, who are experimentalists, went into theory is the following. When we during the beginning of the 1970's measured photo electron spectra of organic molecules, it appeared to be impossible to understand them by use of available theoretical calculations. To handle hydrocarbons we ( together with C. Fridh ) constructed in 1972 a purely empirical procedure, SPINDO [1] which has proved to be useful, but the extension to molecules with hetero atoms appeared to be difficult. One of us ( L.A.) proposed then another purely ~~E!E!~~! EE2~~~~E~ ( Hydrogenic Atoms in Molecules, HAM/1, unpublished), in which the Fock matrix elements f5.y were parametrized using Slater's shielding concept. The self-repulsion was compensated by a term '-1'. The ~~2~~_~ff2E~, HAM/2 [2] , started from the total energy E:. of the molecule. The atomic parts of L used the Slater shielding constants, and the bond parts of E. were taken from SPINDO. The Fock matrix elements Fpv were then obtained from E in a conventional way.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 304 pp. Englisch.

Growing specialization and diversification have brought a host of monographs and textbooks on increasingly specialized topics. However, the 'tree' of knowledge of mathematics and related fields does not grow only by putting forth new brancheq. It also happens, quite often in fact, that branches which were thought to be completely disparate are suddenly seen to be related. Further, the kind and level of sophistication of mathematics applied in various sciences has changed drastically in recent years: measure theory is used (non-trivially) in regional and theoretical economics, algebraic geometry interacts with physics; the Minkowsky lemma, coding theory and the structure of water meet one another in packing and covering theory; quantum fields, crystal defects and mathematical programming profit from homotopy theory; Lie algebras are relevant to filtering; and prediction and electrical engineering can use Stein spaces. And in addition to this there are such new emerging subdisci fI plines as 'experimental mathematics', 'CFD , 'completely integrable systems', 'chaos, synergetics and large-scale order', which are almost impossible to fit into the existing classification schemes.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.
