This book offers the first systematic account of canard cycles, an intriguing phenomenon in the study of ordinary differential equations. The canard cycles are treated in the general context of slow-fast families of two-dimensional vector fields. The central question of controlling the limit cycles is addressed in detail and strong results are presented with complete proofs. In particular, the book provides a detailed study of the structure of the transitions near the critical set of non-isolated singularities. This leads to precise results on the limit cycles and their bifurcations, including the so-called canard phenomenon and canard explosion. The book also provides a solid basis for the use of asymptotic techniques. It gives a clear understanding of notions like inner and outer solutions, describing their relation and precise structure. The first part of the book provides a thorough introduction to slow-fast systems, suitable for graduate students. The second and third parts will be of interest to both pure mathematicians working on theoretical questions such as Hilbert's 16th problem, as well as to a wide range of applied mathematicians looking for a detailed understanding of two-scale models found in electrical circuits, population dynamics, ecological models, cellular (FitzHugh–Nagumo) models, epidemiological models, chemical reactions, mechanical oscillators with friction, climate models, and many other models with tipping points.
Physical health and mental health are inextricably linked together. Moreover, as the biology of mental illnesses is gradually – and inexorably – being elucidated, the overlap between physical illnesses and mental illnesses has become even more apparent. These observations ‘set the stage’ for readers of this issue of Psychiatric Clinics in which a variety of articles are presented from all aspects of medicine - from emergency mental health to how burn patients heal and cope with the physical and mental outcomes, to coverage of issues such as prolonged stay in the intensive care unit, comorbidities in the elderly, food allergies, depression and other common primary care conditions, and childhood diabetes. A primer on interviewing techniques and role play is presented along with the role of nurses who cross both mental and physical aspects of healthcare and the essential role of a supportive family to the interdiscipinary team .
Metals in the earth's crust are very unevenly distributed and, traditionally, a small number of ore deposits, districts or countries have dominated the world supply and have influenced commodity prices. The importance of exceptionally large, or rich, deposits has greatly increased in the age of globalization when a small number of international corporations dominate the metals market, based on few very large ore deposits, practically anywhere in the world. Search for giant orebodies thus drives the exploration industry: not only the in-house teams of large internationals, but also hundreds of junior companies hoping to sell their significant discoveries to the "big boys". Geological characteristics of giant metallic deposits and their setting and the politico-economic constraints of access to and exploitation in prospective areas have been a "hot topic" in the past fifteen years, but the knowledge generated and published has been one-sided, scattered and fragmented. This is the first comprehensive book on the subject that provides body of solid facts rather than rapidly changing theories, written by author of the Empirical Metallogeny book series and founder of the Data Metallogenica visual knowledge system on mineral deposits of the world, who has had an almost 40 years long international academic and industrial experience. The book will provide abundant material for comparative research in metallogeny, practical information for the explorationists as to where to look for the "elephants", and some inspiration for commodity investors.
Long before a devastating earthquake hit in January 2010, Haiti was one of the most impoverished and oppressed countries in the world. However, in the late 1980s a remarkable popular mobilization known as Lavalas ("the flood") sought to liberate the island from decades of US-backed dictatorial rule. Damming the Flood analyzes how and why the Lavalas governments led by President Jean-Bertrand Aristide were overthrown, in 1991 and again in 2004, by the enemies of democracy in Haiti and abroad. The elaborate campaign to suppress Lavalas was perhaps the most successful act of imperial sabotage since the end of the Cold War. It has left the people of Haiti at the mercy of some of the most rapacious political and economic forces on the planet. Updated with a substantial new afterword that addresses the international response to the earthquake, Damming the Flood is both an invaluable account of recent Haitian history and an illuminating analysis of twenty-first-century imperialism.
