Taschenbuch. Condizione: Neu. Neuware -Viruses, being obligatory parasites of their host cells, rely on a vast supply of cellular components for their replication, regardless of whether infection leads to cell death or to the state of persistence. Animal viruses are providing scientists with relatively simple models to study the molecular biology of genome replication and gene expression. Whereas viruses use, in general, pathways of macromolecular biosynthesis common to the host cell, they have a cunning ability to adopt unusual mechanisms of gene expression and gene replication, provided these special pathways offer an advantage in competition for cellular resources. Any study of viral gene expression and replication is likely to lead also to new insights in cellular metabolism. The discoveries of cis-acting regulatory elements in transcription, the phenomenon of splicing of pre mRNA, and cap-dependent and cap-independent initiation of translation may be cited as examples. In addition, animal virus genomes contain elements and encode proteins that are very useful for the design of vectors for gene cloning and expression in mammalian cells. Apart from the basic interest in their biology, viruses have gained notoriety, of course, because they are pathogens. Human animal viruses may cause diseases ranging from the deadly (AIDS) to the benign (common cold). All studies on animal viruses potentially lead to the development of tools for their control, be it through prevention by immunization or treatment with antiviral drugs. Finally, viruses have yielded invaluable reagents in molecular biology as, for example, the vaccinia virus vector for the expression of foreign genes.…

Taschenbuch. Condizione: Neu. Neuware - Design of High-Performance CMOS Voltage-Controlled Oscillators presents a phase noise modeling framework for CMOS ring oscillators. The analysis considers both linear and nonlinear operation. It indicates that fast rail-to-rail switching has to be achieved to minimize phase noise. Additionally, in conventional design the flicker noise in the bias circuit can potentially dominate the phase noise at low offset frequencies. Therefore, for narrow bandwidth PLLs, noise up conversion for the bias circuits should be minimized. We define the effective Q factor (Qeff) for ring oscillators and predict its increase for CMOS processes with smaller feature sizes. Our phase noise analysis is validated via simulation and measurement results.The digital switching noise coupled through the power supply and substrate is usually the dominant source of clock jitter. Improving the supply and substrate noise immunity of a PLL is a challenging job in hostile environments such as a microprocessor chip where millions of digital gates are present.…

This item is printed on demand - it takes 3-4 days longer - Neuware -Over the last few centuries, science has usurped domains of knowledge that were once the province of religion. At the same time, however, both science and religion have enforced strict boundaries throughout. Science can describe the world to us, but it cannot tell us about meaning or values. This is a compelling case for breaching this barrier - in effect, for a reunification of science and religion. 360 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Written in a provocative, witty, and highly accessible style, this is not only a splendid general introduction to the central questions of consciousness and brain science, but also an answer to some of them. The author -- noted Glaswegian chemist A.G. Cairns-Smith -- believes our feelings and sensations are not simply alternative descriptions of neural events but have themselves evolved and have physical effects in the brain as well as physical causes. Secrets of the Mind portrays a vision of the world as it may come to be seen by a future science. Sand, sea water, air, and the atoms from which such materials are made are now well understood by science, but the same can not be said of our personal feelings, our sensations and emotions. Science tells us that these too must be forms of quantum energy if they evolved, yet is only now beginning to explain how. 248 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Describing more than two centuries of epidemic meningitis, In the Blink of an Eye introduces a deadly and frightening bacterial infection of the brain one that afflicts healthy children and young adults in dramatic fashion, often changing or taking lives in just hours or days. Meningococcal meningitis is the culprit causing sporadic cases as well as explosive, unpredictable outbreaks of disease throughout the world leading to the deaths of dozens to hundreds of thousands every year. Beginning with the case of a healthy teenage boy who rapidly succumbs to the disease, the book traces meningitis through its various social contexts. From the acceptance of the germ theory of disease and the birth of the sister sciences of microbiology and immunology in the nineteenth century to the modern molecular era, the story traverses more than 200 years of medical history. It leads us through the early descriptions of the disease, its impact on military forces, large outbreaks of meningitis in Africa and elsewhere, and the evolution of approaches to its treatment, control, and prevention. In so doing, we witness the development of modern medical research and education, the discovery of antibiotics, the rapid emergence of drug-resistant bacteria, the invention of a novel class of vaccines, and learn the inner workings of disease processes and the human immune system. The story of meningococcal meningitis winding through the evolution of infectious diseases, the great European capitals of nineteenth century science, the Rockefeller Institute, the dye industry, Nazi Germany, military medicine, the Vietnam era, and prospects for an end to epidemic disease parallels the rise of modern medical science. 160 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The US healthcare system faces numerous difficulties: uncontrolled increases in costs; major access problems; doctor shortages; closing practices; inefficiencies; decreasing revenues; shrinking bottom lines; large numbers of uninsured and underinsured patients; and the upcoming increased demands in service posed by the Affordable Care Act. As a result, many physicians and health care organications are turning to group visits to address these problems.While Dr. Noffsinger's textbook Running Group Visits In Your Practice is the cornerstone reference on designing, implementing and running shared medical appointments (SMAs) in one's practice, it lacks the simplicity and practicality that clinicians are looking for to start their own SMA programs. The ABCs of Group Visits is a practical, streamlined and step-by-step guide focused on the implementation aspects of group visits.Healthcare professionals at every level are looking for alternate ways to deliver high quality care at lower cost, and it is clear to many that group visits provide a care delivery model that will address many of today's critical challenges. The ABCs of Group Visits quickly provides a solution for your busy practice. 372 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Sustainability applies to everybody. But everybody applies it differently, by defining and shaping it differently-much as water is edged and shaped by its container. It is conceived in absolute terms but underpinned by a great diversity of relatively 'green'-and sometimes contradictory-practices that can each make society only more or less sustainable. In Practicing Sustainability , chefs, poets, music directors, evangelical pastors, skyscraper architects, artists, filmmakers, as well as scientific leaders, entrepreneurs, educators, business executives, policy makers, and the contrarians, shed light on our understanding of sustainability and the role that each of us can play. Each contributor addresses what sustainability means, what is most appealing about the concept, and what they would like to change to improve the perception and practice of sustainability. What emerges from their essays is a wide spectrum of views that confirm an important insight: Sustainability is pursued in different ways not only due to different interpretations, but also because of varying incentives, trade-offs, and altruistic motives. Practicing and achieving sustainability starts with a willingness to look critically at the concept. It also means enabling rich and vigorous discussion based on pragmatism and common sense to determine a framework for best ideas and practices. With time and the much needed critical thinking, sustainable development will become a more integral part of our culture. By sharing experiences and crisp insights from today's savants, Practicing Sustainability serves as a stepping stone to the future. 280 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -While mathematics students generally meet the Riemann integral early in their undergraduate studies, those whose interests lie more in the direction of applied mathematics will probably find themselves needing to use the Lebesgue or Lebesgue-Stieltjes Integral before they have acquired the necessary theoretical background. This book is aimed at exactly this group of readers. The authors introduce the Lebesgue-Stieltjes integral on the real line as a natural extension of the Riemann integral, making the treatment as practical as possible. They discuss the evaluation of Lebesgue-Stieltjes integrals in detail, as well as the standard convergence theorems, and conclude with a brief discussion of multivariate integrals and surveys of L spaces plus some applications. The whole is rounded off with exercises that extend and illustrate the theory, as well as providing practice in the techniques. 244 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This revised and updated fourth edition designed for upper division courses in linear algebra includes the basic results on vector spaces over fields, determinants, the theory of a single linear transformation, and inner product spaces. While it does not presuppose an earlier course, many connections between linear algebra and calculus are worked into the discussion. A special feature is the inclusion of sections devoted to applications of linear algebra, which can either be part of a course, or used for independent study, and new to this edition is a section on analytic methods in matrix theory, with applications to Markov chains in probability theory. Proofs of all the main theorems are included, and are presented on an equal footing with methods for solving numerical problems. Worked examples are integrated into almost every section, to bring out the meaning of the theorems, and illustrate techniques for solving problems. Many numerical exercises make use of all the ideas, and develop computational skills, while exercises of a theoretical nature provide opportunities for students to discover for themselves. 364 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -While the analysis is not the first to investigate empirically the effects of different individual or household factors on school access and completion of Ghanaians, it extends previous work by simultaneously incorporating individual, household, community, regional and national characteristics and also illustrates the latest evidence by applying international data sources and unusually detailed household survey data for a sub-Saharan country. Its focus is threefold: (i) gaining a richer understanding of which external influences hinder educational access and attainment in Ghana, (ii) how to better tackle these challenges and (iii) analyzing how educational development affects the country's overall development. An interview with the Minister of Education helps guide the policy orientation of the analysis by identifying several critical challenges and areas of needed policy attention. Findings from the data analysis indicate that the geographic divide between the North and South, increased economic growth, demographic pressure and a number of individual, household and community factors especially children's nutritional and labour status are the most important challenges in increasing levels of education among Ghanaians in years to come. Finally, the analysis pilots a new and comprehensive results- and capacity-focused policy matrix to help the Government of Ghana realign policy priorities and reform existing programs. To this end, respective policy levers on the demand- and supply-side are discussed, with particular reference to external and demand-side interventions which have not received the necessary attention at the policy-level to improve educational opportunities and outcomes at all levels. 156 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Data Correcting Approaches in Combinatorial Optimization focuses on algorithmic applications of the well known polynomially solvable special cases of computationally intractable problems.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Lectures on Finitely Generated Solvable Groups are based on the 'Topics in Group Theory' course focused on finitely generated solvable groups that was given by Gilbert G. Baumslag at the Graduate School and University Center of the City University of New York. While knowledge about finitely generated nilpotent groups is extensive, much less is known about the more general class of solvable groups containing them. The study of finitely generated solvable groups involves many different threads; therefore these notes contain discussions on HNN extensions; amalgamated and wreath products; and other concepts from combinatorial group theory as well as commutative algebra. Along with Baumslag's Embedding Theorem for Finitely Generated Metabelian Groups, two theorems of Bieri and Strebel are presented to provide a solid foundation for understanding the fascinating class of finitely generated solvable groups. Examples are also supplied, which help illuminate many of the key concepts contained in the notes. Requiring only a modest initial group theory background from graduate and post-graduate students, these notes provide a field guide to the class of finitely generated solvable groups from a combinatorial group theory perspective. 68 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Latinos are the fastest growing and largest minority group in the United States. In 2008, this group numbered over 47 million; by 2050, the population is expected to triple, reaching 133 million. Traditionally, Latinos have immigrated to large urban centers (e.g., New York, Los Angeles) that over long periods of time developed a complex infrastructure to receive new immigrants. Increasingly, new Spanish-speaking immigrants are moving into areas of the country previously unfamiliar to them. Although urban co-ethnic communities continue to be the destination of many newcomers, immigrants from Mexico, Central America, and South America in pursuit of low-skilled labor opportunities are settling in small towns and rural areas of the South and Midwest. This new demographic trend has resulted in the creation of the term 'new growth communities,' which refers to small rural areas that are now home to a small but rapidly growing Hispanic population. Unfortunately, these communities, which are now present in many states across the country (e.g., Illinois, North Carolina), lack the infrastructure necessary to meet the needs of Latino immigrants (e.g., access to health care, immigration assistance, and breaking down language barriers). The lack of an infrastructure and the lack of an established ethnic community to facilitate the assimilation of new immigrants present an ongoing challenge, especially in the area of Latino mental health. The volume focuses on dealing with systemic issues and on providing innovative ideas for development of infrastructure of services. This text will advance ways to understand and ameliorate mental health disparities both from research and experiential perspectives. 304 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The ideas of probability are all around us. Lotteries, casino gambling, the al most non-stop polling which seems to mold public policy more and more these are a few of the areas where principles of probability impinge in a direct way on the lives and fortunes of the general public. At a more re moved level there is modern science which uses probability and its offshoots like statistics and the theory of random processes to build mathematical descriptions of the real world. In fact, twentieth-century physics, in embrac ing quantum mechanics, has a world view that is at its core probabilistic in nature, contrary to the deterministic one of classical physics. In addition to all this muscular evidence of the importance of probability ideas it should also be said that probability can be lots of fun. It is a subject where you can start thinking about amusing, interesting, and often difficult problems with very little mathematical background. In this book, I wanted to introduce a reader with at least a fairly decent mathematical background in elementary algebra to this world of probabil ity, to the way of thinking typical of probability, and the kinds of problems to which probability can be applied. I have used examples from a wide variety of fields to motivate the discussion of concepts. 264 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Expert testimony relying on scientific and other specialized evidence has come under increased scrutiny by the legal system. A trilogy of recent U.S. Supreme Court cases has assigned judges the task of assessing the relevance and reliability of proposed expert testimony. In conjunction with the Federal judiciary, the American Association for the Advancement of Science has initiated a project to provide judges indicating a need with their own expert. This concern with the proper interpretation of scientific evidence, especially that of a probabilistic nature, has also occurred in England, Australia and in several European countries. Statistical Science in the Courtroom is a collection of articles written by statisticians and legal scholars who have been concerned with problems arising in the use of statistical evidence. A number of articles describe DNA evidence and the difficulties of properly calculating the probability that a random individual's profile would 'match' that of the evidence as well as the proper way to intrepret the result. In addition to the technical issues, several authors tell about their experiences in court. A few have become disenchanted with their involvement and describe the events that led them to devote less time to this application. Other articles describe the role of statistical evidence in cases concerning discrimination against minorities, product liability, environmental regulation, the appropriateness and fairness of sentences and how being involved in legal statistics has raised interesting statistical problems requiring further research. 468 pp. Englisch.…

A vner Friedman Robert Gulliver v PREFACE During the last few years the numerical techniques for the solution of elliptic problems, in potential theory for example, have been drastically improved. Several so-called fast methods have been developed which re duce the required computing time many orders of magnitude over that of classical algorithms. The new methods include multigrid, fast Fourier transforms, multi pole methods and wavelet techniques. Wavelets have re cently been developed into a very useful tool in signal processing, the solu tion of integral equation, etc. Wavelet techniques should be quite useful in many wave propagation problems, especially in inhomogeneous and nonlin ear media where special features of the solution such as singularities might be tracked efficiently. 308 pp. Englisch.…
