Taschenbuch. Condizione: Neu. Neuware -This book contains the refereed papers which were presented at the interna tional conference on 'Multivariate Approximation and Splines' held in Mannheim, Germany, on September 7-10,1996. Fifty experts from Bulgaria, England, France, Israel, Netherlands, Norway, Poland, Switzerland, Ukraine, USA and Germany participated in the symposium. It was the aim of the conference to give an overview of recent developments in multivariate approximation with special emphasis on spline methods. The field is characterized by rapidly developing branches such as approximation, data fit ting, interpolation, splines, radial basis functions, neural networks, computer aided design methods, subdivision algorithms and wavelets. The research has applications in areas like industrial production, visualization, pattern recognition, image and signal processing, cognitive systems and modeling in geology, physics, biology and medicine. In the following, we briefly describe the contents of the papers. Exact inequalities of Kolmogorov type which estimate the derivatives of mul the paper of BABENKO, KOFANovand tivariate periodic functions are derived in PICHUGOV. These inequalities are applied to the approximation of classes of mul tivariate periodic functions and to the approximation by quasi-polynomials. BAINOV, DISHLIEV and HRISTOVA investigate initial value problems for non linear impulse differential-difference equations which have many applications in simulating real processes. By applying iterative techniques, sequences of lower and upper solutions are constructed which converge to a solution of the initial value problem.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 340 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This volume contains a selection of invited papers, presented to the fourth In Statistical Analysis Based on the L1-Norm and Related ternational Conference on Methods, held in Neuchatel, Switzerland, from August 4-9, 2002. Organized jointly by the University of Illinois at Chicago (Gib Bassett), the Rutgers University (Regina Liu and Yehuda Vardi) and the University of Neuchatel (Yadolah Dodge), the conference brought together experts whose research deals with theory and ap plications involving the L1-Norm. The conference included invited and contributed talks as well as a tutorial on Quantile Regression. This volume includes 36 refereed invited papers under seven headings. Part one deals with Quantiles in all their forms and shapes. It includes papers on quantile functions in non-parametric multivariate analysis, and empirical applications of quantile regression. Much of the development in this direction follows from the fundamental paper by Koenker and Bassett in 1978. Financial and Time Series A nalysis follows the section on quantiles. Part three concerns Estimation, Testing and Characterization. Part four, Deep in the Data, deals with issues related to data depth. Part five addresses Classification questions. The problem of Density Estimation and Image Processing is discussed in Part six, and finally Part seven presents two environmental applications. The contributions represent clear evidence of important research involving theo retical issues and applications associated with the L1-Norm. It is my hope that the articles contained in this volume and its predecessors, published in 1987, 1992, and 1997, will stimulate interest among researchers.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 472 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -These two volumes constitute texts for graduate courses in linear operator theory. The reader is assumed to have a knowledge of both complex analysis and the first elements of operator theory. The texts are intended to concisely present a variety of classes of linear operators, each with its own character, theory, techniques and tools. For each of the classes, various differential and integral operators motivate or illustrate the main results. Although each class is treated seperately and the first impression may be that of many different theories, interconnections appear frequently and unexpectedly. The result is a beautiful, unified and powerful theory. The classes we have chosen are representatives of the principal important classes of operators, and we believe that these illustrate the richness of operator theory, both in its theoretical developments and in its applicants. Because we wanted the books to be of reasonable size, we were selective in the classes we chose and restricted our attention to the main features of the corresponding theories. However, these theories have been updated and enhanced by new developments, many of which appear here for the first time in an operator-theory text. In the selection of the material the taste and interest of the authors played an important role.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 572 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -An exploration of the theory of discrete integrable systems, with an emphasis on the following general problem: how to discretize one or several of independent variables in a given integrable system of differential equations, maintaining the integrability property This question (related in spirit to such a modern branch of numerical analysis as geometric integration) is treated in the book as an immanent part of the theory of integrable systems, also commonly termed as the theory of solitons. Most of the results are only available from recent journal publications, many of them are new.Thus, the book is a kind of encyclopedia on discrete integrable systems. It unifies the features of a research monograph and a handbook. It is supplied with an extensive bibliography and detailed bibliographic remarks at the end of each chapter. Largely self-contained, it will be accessible to graduate and post-graduate students as well as to researchers in the area of integrable dynamical systems.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 1124 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware - 1. Historical Remarks Convex Integration theory, first introduced by M. Gromov [17], is one of three general methods in immersion-theoretic topology for solving a broad range of problems in geometry and topology. The other methods are: (i) Removal of Singularities, introduced by M. Gromov and Y. Eliashberg [8]; (ii) the covering homotopy method which, following M. Gromov's thesis [16], is also referred to as the method of sheaves. The covering homotopy method is due originally to S. Smale [36] who proved a crucial covering homotopy result in order to solve the classification problem for immersions of spheres in Euclidean space. These general methods are not linearly related in the sense that succes sive methods subsumed the previous methods. Each method has its own distinct foundation, based on an independent geometrical or analytical insight. Conse quently, each method has a range of applications to problems in topology that are best suited to its particular insight. For example, a distinguishing feature of Convex Integration theory is that it applies to solve closed relations in jet spaces, including certain general classes of underdetermined non-linear systems of par tial differential equations. As a case of interest, the Nash-Kuiper Cl-isometrie immersion theorem ean be reformulated and proved using Convex Integration theory (cf. Gromov [18]). No such results on closed relations in jet spaees can be proved by means of the other two methods.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 228 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Epidemiological studies of Chronic Bronchitis/ Chronic Obstructive Airway Disease (CB/COAD) have demonstrated that hypersecretory glandular activity, as weIl as infections, are not the most important risk factors determining the serious decline in lung function in this disease. Instead, inflammatory indices are emerging as characteristic features of the pathology and pathophysiology of CB/COAD. It is possible that continuous inflammatory processes cause structural changes and thus provide the anatomical basis for airway obstruction which, once estab lished, is only partly reversible. We feIt it was timely to gather leading international researchers who could provide critical updates on CB/COAD, its pathology and clinical/ experimental assessments. The latter aspect included not only the fundamentals of airway function but also, and in greater detail, cellular and solute indices which can now be used to determine inflammation in CB/COAD. The meeting was made possible by a grant from Draco/Astra (Sweden and Finland). We particularly acknowledge the expert assistance of Mrs. Eva Engberg in all facets of the present work. 296 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Since prostaglandins were first proposed as mediators of in flammation some eight years ago, there have been a variety of arachidonic acid metabolites discovered including the thromboxa nes, prostacyclin, prostaglandin endoperoxides and lipoxygenase products such as SRS-A. All of them have subsequently been shown to have significant and specific biological activities not only in inflammatory responses but also in other physiological pro cesses. The explosion of research in this area has been an indi cation of the importance of this field but has also meant that it is time for an evaluation of activities of prostaglandins and products of the arachidonate pathway - collectively described as eicosanoids. For this reason the organizers of this conference felt it was timely to bring together workers in the field and critically evaluate some aspects of the role of different eico sanoids in inflammatory responses and the action of the anti inflammatory agents drugs used to modulate or inhibit these responses. The conference held at King's College Hospital Medical School produced lively and constructive discussions. While there are still many complexities to be investigated several important conclusions did emerge. The organizers were grateful to have the use of facilities at Normanby College and King's College Hospi tal. Also we would like to thank the Boots Company Ltd. , for generous sponsorship and Mrs. P. Carter for valuable secretarial assistance. K. D. Rainsford A. W. Ford-Hutchinson M. J. H. Smith Organizers. Lewis 7 INTRODUCTION TO PROSTAGLANDINS AND INFLAMMATION G. P. 248 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -In September 1998, during the 'International Workshop on Analysis and Vibrat ing Systems' held in Canmore, Alberta, Canada, it was decided by a group of participants to honour Peter Lancaster on the occasion of his 70th birthday with a volume in the series 'Operator Theory: Advances and Applications'. Friends and colleagues responded enthusiastically to this proposal and within a short time we put together the volume which is now presented to the reader. Regarding accep tance of papers we followed the usual rules of the journal 'Integral Equations and Operator Theory'. The papers are dedicated to different problems in matrix and operator theory, especially to the areas in which Peter contributed so richly. At our request, Peter agreed to write an autobiographical paper, which appears at the beginning of the volume. It continues with the list of Peter's publications. We believe that this volume will pay tribute to Peter on his outstanding achievements in different areas of mathematics. 1. Gohberg, H.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume of 'Agents and Actions Supplements' provided a challenge to the editors, the authors and the publisher. It was our aim to complete the book in advance of the lectures to be given at the 'International Symposium on Asthma and Allergic Diseases in Childhood', in Berne, Switzerland, on March 25th-27th, 1993. This symposium commemorates the 10th anniversary of the Swiss Association of Parents of Asthmatic and Allergic Children. The incidence of asthma and allergies generally is on the increase and demands everyone's attention, including that of physicians, researchers, allied health professionals and parents. There have been no recent breakthroughs in our understanding of asthma pathogenesis or treatment. However, forms of treatment, pathogenetic insights and public awareness are undergoing rapid changes as our knowledge of atopic diseases increases. For this reason we chose the title 'Update on Childhood Asthma'. The purpose of the papers is to summarize recent research results, to provide an update on the current approach to therapeutic interventions and to alert readers to the psychosomatic aspects of asthma. Whether the state of knowledge has already changed while you are holding this book in your hands is not so much dependent on a delay in publishing but on the speed of appearance of new research results. Fortunately, our ambitious target to edit the proceedings in advance of the conference has been successful. This was only possible because of the timely submission of papers, the speed of publication and the enthusiasm of the editors. 236 pp. Englisch.

The afternoons were free for discussion and recreation but delegates reassanbled with the help of Hunter Valley Wines two hours before dinner to review the many posters presented. On the evenings of the 27th and 28th May, four review lectures were given by J. Dingle (The role of messengers of the IL-I/Catabolin type in cartilage turnover), R.

Roughl ey (Cha nges in proteoglycan structure duri ng cartil age agei ng - ori gi n and effects). The workshop sessions and review lectures, while intense, provided much new data in the areas defined and provided useful debates on controversial issues, which in some instances still remain unresolved. However, the relaxed, informal atmosphere of the Salamander Bay resort provided the greatest incentive for open discussion, the renewal of old, and establishment of new, friendships, all of which are important aspects of our scientific community. While it was not possible to publish all the papers presented at the Salamander Bay Symposium, I trust that those contained herei n will provide some indication of the overall quality and scope of the meeting.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The human immune system, despite having its own sophisticated defence mecha nisms, is inferior to bacteria and viruses with respect to adaptability. Furthermore, our immune system is increasingly exposed to detrimental effects, that is immuno suppressive environmental consequences, unhealthy living, and chronic illnesses. Excessive chemotherapy threatens our immune system even further. This situation demands compensatory prophylactic therapeutic regimes. One of these - specific immunostimulation - is more difficult to achieve than the immunosuppression cur rently used in transplantation surgery and the medical treatment of autoimmune dis eases. The earliest attempts to develop suitable medication for immunostimulation were based on traditional remedies which embodied the accumulated experience of several centuries. Medicinal plants are already being used prophylactically as stan dardized and efficacy-optimized preparations for the treatment of various recur rent infections, or in combination with chemotherapeutics in standard medical practice. In order to rationally apply immunostimulants of plant origin, however, it is necessary to search for the active principles of these substances and to produce them in a pure form. Because suitable screening methods have become available only recently, research in this field is in its very beginning. Further progress can be expected from systematic basic research on the mechanisms underlying immunomodulation. This also applies to verification of clinical efficacy, which is a prerequisite for the acceptance of medications with purported immunostimulatory properties. 388 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Lung cancer is a disease with pandemic public health implications as it is now the leading cause of cancer mortality throughout the world. This book results from two recent International Association for the Study of Lung Cancer (IASLC) Workshops on lung cancer prevention. It strikes a balance between considering public health approaches to tobacco control and population-based screening, advances in clinical evaluation of chemoprevention approaches, and the biology of lung carcinogenesis. Indeed, while the science of smoking cessation is evolving as new pharmacological tools are moving into clinical evaluation, the current impact of molecular diagnostics is profound. The rapidly-evolving diagnostic technologies are revolutionizing basic scientific investigation of cancer, and this trend is expected to soon spill over into the clinical practice of medicine. The evolution of economical diagnostic platforms to allow for direct bronchial epithelial evaluation in high-risk populations promises to improve the diagnostic lead-time for this disease. The hope is that enough progress will occur to permit lung cancer detection in advance of clinical cancer so that the disease can be addressed early on, while it is still confined to the site of origin. Chemoprevention, which is designed to intervene in the early phase of carcinogenesis prior to any subjective clinical manifestation of a cancer, is also generating greater research interest. Moreover, the benefit of aerosolized administration of chemoprevention agents over conventional oral administration has strong appeal and may result in the reduction of the incidence of cancer when combined with new diagnostic technologies. 348 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the Proceedings of the International Workshop Variational Methods For Discontinuous Structures, which was jointly organized by the Dipar timento di Matematica Francesco Brioschi of Milano Politecnico and the Interna tional School for Advanced Studies (SISSA) of Trieste. The Conference took place at Villa Erba Antica (Cernobbio) on the Lago di Como on July 4- 6, 2001. In past years the calculus of variations faced mainly the study of continuous structures, say particularly problems with smooth solutions. One of the deepest and more delicate problems was the regularity of weak solutions. More recently, new sophisticated tools have been introduced in order to study discontinuities: in many variational problems solutions develop singularities, and sometimes the most interesting part of a solution is the singularity itself. The conference intended to focus on recent developments in this direction. Some of the talks were devoted to differential or variational modelling of image segmentation, occlusion and textures synthesizing in image analysis, varia tional description of micro-magnetic materials, dimension reduction and structured deformations in elasticity and plasticity, phase transitions, irrigation and drainage, evolution of crystalline shapes; in most cases theoretical and numerical analysis of these models were provided. viii Preface Other talks were dedicated to specific problems of the calculus of variations: variational theory of weak or lower-dimensional structures, optimal transport prob lems with free Dirichlet regions, higher order variational problems, symmetrization in the BV framework. 204 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Our goal is to find Grabner bases for polynomials in four different sets of expressions: 1 x- , (1 - x)-1 (RESOL) X, 1 x- (1 - xy)-1 (EB) X, , y-1, (1-yx)-1 y, (1_y)-1 (1-x)-1 (preNF) (EB) plus and (1 - xy)1/2 (1 - yx )1/2 (NF) (preNF) plus and Most formulas in the theory of the Nagy-Foias operator model [NF] are polynomials in these expressions where x = T and y = T\*. Complicated polynomials can often be simplified by applying 'replacement rules'. For example, the polynomial (1 - xy)-2 - 2xy(1-xy)-2 + xy2 (1 - xy)-2 -1 simplifies to O. This can be seen by three applications of the replacement rule (1-xy) -1 xy -t (1 - xy)-1 -1 which is true because of the definition of (1-xy)-1. A replacement rule consists of a left hand side (LHS) and a right hand side (RHS). The LHS will always be a monomial. The RHS will be a polynomial whose terms are 'simpler' (in a sense to be made precise) than the LHS. An expression is reduced by repeatedly replacing any occurrence of a LHS by the corresponding RHS. The monomials will be well-ordered, so the reduction procedure will terminate after finitely many steps. Our aim is to provide a list of substitution rules for the classes of expressions above. These rules, when implemented on a computer, provide an efficient automatic simplification process. We discuss and define the ordering on monomials later. 422 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Massively Parallel Systems (MPSs) with their scalable computation and storage space promises are becoming increasingly important for high-performance computing. The growing acceptance of MPSs in academia is clearly apparent. However, in industrial companies, their usage remains low. The programming of MPSs is still the big obstacle, and solving this software problem is sometimes referred to as one of the most challenging tasks of the 1990's. The 1994 working conference on 'Programming Environments for Massively Parallel Systems' was the latest event of the working group WG 10.3 of the International Federation for Information Processing (IFIP) in this field. It succeeded the 1992 conference in Edinburgh on 'Programming Environments for Parallel Computing'. The research and development work discussed at the conference addresses the entire spectrum of software problems including virtual machines which are less cumbersome to program; more convenient programming models; advanced programming languages, and especially more sophisticated programming tools; but also algorithms and applications. 423 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Rapid progress has been made in our understanding of the molecular mechanisms of cell growth and oncogenesis during the past decade. Special attention has been given to the presentation of the frequently neglected close correlation between changes in signal transduction and metabolic pathways during oncogenesis. This book advances the knowledge of mechanisms regulating metabolism and functioning of vitamin A and offers the most recent results of research on the clinical efficiency of retinoids in skin disorders and cancer. The book presents recent findings on the regulation of cell growth in normal and neoplastic tissues by growth factors including hormones, and by the activation and inactivation of oncogenes and tumor suppressor genes, respectively. It also offers a survey of the molecular and cell biochemistry of retinoids. Basic researchers in biochemistry, pharmacology and cell biology as well as clinicians will find this book very informative and up-to-date.
