Selected as a Winner of the National Poetry Series by Mary Jo Bang Sarah Vap’s sixth work of poetry, Viability is an ambitious and highly imaginative collection of prose poems that braids together several kinds of language strands in an effort to understand and to ask questions about the bodies (and minds, maybe even souls) that are owned by capitalism. These threads of language include definitions from an online financial dictionary, samples from an essay on the economics of slavery, quotations from an article about slavery in today’s Thai fishing industry, lyric bits and pieces about pregnancy and infants of all kinds, and a wealth of quotations falsely attributed to John of the Cross. The viability that Vap is asking about is primarily economic and biological (but not only). The questions of viability become entwined with the need, across the book, to “increase”—in both a capitalist and a gestational sense. John of the Cross tries, at first with composure, to comment on or to mediate between all the different strands of the collection.

In the past few years it has become clear that left ventricular dysfunction, even of severe degree, may be reversible after coronary revascularization in some patients. As a result, myocardial viability has captured the imagination of researchers and clinicians seeking to unravel the cellular and subcellular mechanisms and define appropriate diagnostic modalities. These diagnostic modalities include: cardiac catheterization, positron-emission tomography, magnetic resonance imaging, two-dimensional echocardiography and single-photon imaging. This book, for the first time, brings together a diverse array of information in a comprehensive and concise fashion using a template of ten chapters written by experts in the field. It will be required reading for cardiologists, radiologists, nuclear medicine specialists, cardiac surgeons, anesthesiologists, internists and basic researchers and their trainees who are involved in the management of patients with coronary artery disease in whom myocardial viability is a clinically relevant issue.

One common characteristics of a complex system is its ability to withstand major disturbances and the capacity to rebuild itself. Understanding how such systems demonstrate resilience by absorbing or recovering from major external perturbations requires both quantitative foundations and a multidisciplinary view on the topic. This book demonstrates how new methods can be used to identify the actions favouring the recovery from perturbations. Examples discussed include bacterial biofilms resisting detachment, grassland savannahs recovering from fire, the dynamics of language competition and Internet social networking sites overcoming vandalism. The reader is taken through an introduction to the idea of resilience and viability and shown the mathematical basis of the techniques used to analyse systems. The idea of individual or agent-based modelling of complex systems is introduced and related to analytically tractable approximations of such models. A set of case studies illustrates the use of the techniques in real applications, and the final section describes how one can use new and elaborate software tools for carrying out the necessary calculations. The book is intended for a general scientific audience of readers from the natural and social sciences, yet requires some mathematics to gain a full understanding of the more theoretical chapters. It is an essential point of reference for those interested in the practical application of the concepts of resilience and viability

AMI E. ISKANDRIAN & ERNST E. VAN DER WALL The first edition of this book was published in 1994. Since then important advances have occurred in the field of myocardial viability. This, coupled with increasing interest by the scientific community in the broader issues of its relevance to patient care, suggested to us the need to write the second edition. We are most fortunate to have the help of a distinguished group of experts who have helped shape the field; we appreciate their commitments and contributions. Almost all chapters have been radically modified. Chapter 1 deals with pathophysiology of myocardial hibernation and stunning; Chapter 2 with apoptosis; Chapter 3 with the role of positron emission tomography; Chapters 4 and 5 with the role of single photon emission computed tomography with thallium-201 and technetium agents, respectively; Chapter 6 with the role of SPECT fatty acid imaging; Chapter 7 with the role of SPECT FDG imaging; Chapter 8 with the role of cardiac catheterization angiography; Chapter 9 with the role of echocardiography; Chapter 10 with the role of magnetic resonance imaging; and Chapter 11 with clinical applications. Finally, Chapter 12 provides a short summary.

The problem of viability of hybrid systems is considered in this work. A model for a hybrid system is developed including a means of including three forms of uncertainty: transition dynamics, structural uncertainty, and parametric uncertainty. A computational basis for viability of hybrid systems is developed and applied to three control law classes. An approach is developed for robust viability based on two extensions of the controllability operator. The three-tank example is examined for both the viability problem and robust viability problem. The theory is applied through simulation to an active magnetic bearing system and to a batch polymerization process showing that viability can be satisfied in practice. The problem of viable attainability is examined based on the controllability operator approach introduced by Nerode and colleagues. Lastly, properties of the controllability operator are presented.

From prehistoric times man has had a pecial s relationship with seed plants - as a source of food, materials for tools, buildings, clothing and pharmaceuticals, and for ornamenting his surroundings for his own delight (probably in that chronological order which, incidentally, also gives some indication ofthe priorities oflife). Today man's most important staple foods are derived directly from seeds as they have been since neolithic times. (It is a sobering thought, as Harlan* has pointed out, that nothing significant has been added to his diet since then. ) From those times he must have learned to collect, conserve and cultivate seeds; and the accumulated experience has been handed down. This book then is part of an ancient tradition, for here we are still primarily concerned with these skills. Seeds are plant propagules comprised of embryos in which growth has been suspended, usually supplied with their own food reserves and protected by special covering layers. Typically they are relatively dry structures compared with other plant tissues and, in this condi tion) they are resistant to the ravages of time and their environment. But resistant is a relative tenn and seeds do deteriorate: the type, the extent and the rapidity of the deterioration, and the factors which control it are important to agronomists, horticulturalists, plant breeders, seedsmen, seed analysts, and those concerned with the conservation of genetic resources.

This book presents the Entrepreneurship Viability Index (EVI) as a focal point to define other novel indices. It also introduces readers to new concepts and metrics of entrepreneurship to help measure the lifespan of entrepreneurial activities and quantify the capabilities of entrepreneurs as well as the share of efficient businesses at the country level. Using a variety of mathematical models and providing details for each category of business, EVI is measured as the ratio of the ‘rate of entrepreneurial activities’ to the ‘rate of exit from the business’, reflecting the sustainability, durability, business success, and status of entrepreneurial activities in a country. These metrics offer a unique opportunity for researchers and policymakers to assess the status of efficient entrepreneurial activities, which influence the economy, and to study economic resistance in the event of economic shocks or recessions. The book provides valuable information on various key concepts in entrepreneurship, such as the interaction of individual and environmental factors, motivation and entrepreneurial activities, which allow the prediction of entrepreneurship treatment across countries. This in turn plays a significant role in identifying the factors that secure or threaten a country’s business sector. The book helps readers, researchers, policymakers, lenders, "angel investors" and anyone with a financial interest in entrepreneurial businesses to understand how even more viable businesses could be created than is the case today, and to recognize new categories of budding entrepreneurs.
