Limit Cycles of Differential Equations
Contains the lecture series originally delivered at the "Advanced Course on Limit Cycles of Differential Equations" in the Centre de Recerca Matemàtica Barcelona in 2006.The topics covered are the center-focus problem for polynomial vector fields, and the application of abelian integrals to limit cycle bifurcations. Both topics are related to Hilbert's sixteenth problem. In particular, the book will be of interest to students and researchers working in the qualitative theory of dynamical systems.
Light Absorption in Sea Water
Takes a fresh, holistic approach to the problems of light absorption and absorbers in seawaters, discussing the fundamentals of light absorption at various depths in seawaters of different trophicity by absorbers of diverse origin. The authors have drawn their information from a substantial body of contemporary research results published in the subject literature (over 700 references) as well as their own work during the last 30 years. No other book presently available examines the issues of light absorption and absorbers in seawaters in such a manner. The physical and chemical properties, as well as the optical constants, of organic and inorganic suspended particulate matter (SPM), are discussed in the context of their relationship to the light absorption properties of SPM. Special emphasis is placed on the role of the phytoplankton and the pigments it contains which are particularly strong and important absorbers of visible light in the sea.
Life in the Universe : Expectations and Constraints
Energy, chemistry, solvents, and habitats -- the basic elements of living systems - define the opportunities and limitations for life on other worlds. This class-tested text examines each of these parameters in crucial depth and makes the argument that life forms we would recognize may be more common in our solar system than many assume. It also considers, however, exotic forms of life that would not have to rely on carbon as basic chemical element, solar energy as a main energy source, or water as primary solvent. Finally the question of detecting bio- and geosignature of such life forms is discussed, ranging from Earth environments to deep space. While speculative considerations in this emerging field of science cannot be avoided, the authors have tried to present their study with the breadth and seriousness that a scientific approach to this issue requires. They seek an operational definition of life and investigate the realm of possibilities that nature offers to realize this very special state of matter and avoid scientific jargon wherever possible to make this intrinsically interdisciplinary subject understandable to a broad range of readers.
Life as We Know It
Life As we Know It ["LAKI"] covers several aspects of Life, ranging from the prebiotic level, origin of life, evolution of prokaryotes to eukaryotes and finally to various affairs of human beings. Although it is hard to define Life, one can, however, characterize it and describe its features. Topics treated are categories of bacteria, algae and fungi, conscience, philosophy, theology, aesthetics, appearance of sport and life destiny, life after clinical death, and thoughts of the world to come ("Olam Haba"). The various chapters have been written so that they are accessible to all - from the avid lay reader to the specialist – and make available multidisciplinary sources of information about Life. This volume will interest open minded scholars, students at all levels of general sciences, natural and Life science, researchers of philosophy, theology, history of Life, astrobiology, and those who wish to widen their knowledge about "who are we in the universe".
Les prothèses tricompartimentaires du genou de première intention : Techniques opératoires. Problèmes et solutions = Primary tricompartmental knee replacement : Surgical techniques, problems, and solutions
It seems difficult and presumptuous to want to write a book on total knee replacement. There are many quality works dealing with this subject. The knee prosthesis has, from its origin, particularly in the United States, given rise to considerable studies in all directions: biomechanical, physiological, biological and industrial. Our goal is to offer the youngest a book of simple knowledge without pretension of completeness or prejudice as to long debated subjects (conservation or not of the posterior cruciate ligament, cement or without cement, resurfacing or not of the patella, fixed plate or mobile platform, etc.), and to give practical advice based on our experience. Why limit yourself to first-line tricompartmentals? Because it is the most common solution to the usual degenerative knee problems. In addition, unicompartment and revision prostheses will be the subject of further literature. Everyone knows that to put a knee prosthesis model, and therefore to a system. However, it is important to be able to keep your freedom of analysis in order to maintain your freedom of choice. You have to know how to put on a knee prosthesis without compromise or fanaticism. Convictions are more dangerous enemies of truth than lies. Nietzsche
Les douleurs abdominales en questions : Rôle physiopathologique de la sensibilité viscérale = Abdominal pain in question : The pathophysiological role of visceral sensitivity
The gut-brain axis refers to the network of nerve pathways that connect the myenteric plexus, the veritable "gut brain," to the central nervous system. Nearly 80% of these neurons are sensory neurons, and the afferent pathways that transmit information from the digestive tract to the central nervous system play a crucial role in the physiological regulation of digestive functions, as well as in certain pathological conditions. A large majority of these sensations remain unconscious and give rise to reflex responses. Only those requiring a conscious response reach the level of awareness in a normal state (hunger, thirst, the urge to defecate). In pathological situations, the same is true for painful sensations of digestive origin. Functional bowel disorders are a frequent reason for consultation. Their pathophysiology is now based on a model integrating the various etiological factors around the brain-gut axis. These patients frequently present with visceral hypersensitivity, which manifests as an increased perception of digestive sensations, notably the onset of pain in response to stimuli that are not painful in normal subjects. Recognizing the role of visceral hypersensitivity has made it possible to explain the mechanism of action of medications used to treat functional bowel disorders and paves the way for the development of new molecules acting on digestive afferents. In this book, we will describe the anatomical and physiological basis for understanding the concept of visceral sensitivity and the role of digestive afferents in the pathophysiology of acute and chronic abdominal pain, particularly irritable bowel syndrome.
Les cancers digestifs = Digestive cancers
Digestive tumors are among the most common malignant tumors and represent a major public health problem. This is one of the areas that has evolved the most in recent years in oncology due to significant progress in diagnostic strategies and therapeutic management. It seems essential that this progress be implemented in the daily practice of physicians treating these tumors. This book, the result of multidisciplinary work, provides a practical and up-to-date approach to the management of malignant digestive tumors. The first chapters are devoted to general and original subjects such as epidemiology, genetics, the management of elderly subjects. A second part approaches in a pragmatic and practical way the principles of diagnostic and therapeutic management by localization. A third part, devoted to the practical realization of chemotherapy, takes stock of new therapeutic approaches, oral or locoregional chemotherapy. Finally, the last part of the book is dedicated to digestive cancer emergencies and the palliative management of these tumors.
Lenses and Waves : Christiaan Huygens and the Mathematical Science of Optics in the Seventeenth Century
this book offers the first account of the development of Huygens’ mathematical analysis of lenses and telescopes and its significance for the origin of the wave theory of light. As Huygens applied his mathematical proficiency to practical issues pertaining to telescopes – including trying to design a perfect telescope by means of mathematical theory – his dioptrics is significant for our understanding of seventeenth-century relations between theory and practice. With this full account of Huygens’ optics, this book sheds new light on the history of seventeenth-century optics and the rise of the new mathematical sciences, as well as Huygens’ oeuvre as a whole. Students of the history of optics, of early mathematical physics, and the Scientific Revolution, will find this book enlightening.
Leibniz and the English-Speaking World
These essays comprise a first attempt to assess overall the attention awarded to Leibniz’s philosophy in the English-speaking world in his own time and up to the present day. In addition to an introductory overview there are fourteen original and previously unpublished essays considering Leibniz’s connections with his English-speaking contemporaries and near contemporaries as well as the later reception of his thought in Anglo-American philosophy.

Volume II gathers another set of extensive lectures covering topics so diverse as the formation and the distribution of elements in the Universe, the concept of habitability from both the planetologists' and the biologists' point of view and artificial life. The contributions are held together by the common goal to understand better the origin of life, its evolution and possible existence outside the Earth's realm.
Lectures in astrobiology ; Vol I ; Part 2 : From prebiotic chemistry to the origin of life on earth
The first comprehensive textbook at the graduate level encompassing all aspects associated with the emerging field of astrobiology. Volume I gathers a fist set of extensive lectures that cover a broad range of topics, from the formation of solar system to the quest for the most primitive life forms that emerged on the early Earth.
Le bouddhisme et la médecine traditionnelle de lInde = Buddhism and traditional medicine from India
Aims to return to ancient India, to the sources of Buddhism. It is a question of comparing the religious bodies of Buddhism of the origins with the treatises relating to Ayurveda, the medicine practiced in India at that time.
Layce (Image data poisoning) = لايس (تسميم بيانات الصور )
The ongoing growth of image generative artificial intelligence models was paved with existing drawings and art pieces by great artists both past and present, and while generative models are very useful and helpful, there is the issue of the origin of the datasets trained on, and the morality of usage regarding copyrights and artistic identity. A novel line of defense that helps artists and visual content creators actively protect their pieces emerged, dubbed Data Poisoning and it works by misleading Artificial Intelligence models that attempt to use a Poisoned Image for training, or as a reference, as the Poisoned Image will appear to the human eye identical to the original art piece, while the Artificial Intelligence model will be seeing a remarkably different image, causing generative models to generate false positive results when given a prompt poisoned by the author or when trained on data poisoned by the original owner. This study aims to study image data poisoning methods and technologies, and build an application containing multiple image models, and poisoning models as well, accompanied by a Community for artists to share art and interact with each other.
Lattice : Multivariate Data Visualization with R
R is rapidly growing in popularity as the environment of choice for data analysis and graphics both in academia and industry. Lattice brings the proven design of Trellis graphics (originally developed for S by William S. Cleveland and colleagues at Bell Labs) to R, considerably expanding its capabilities in the process. Lattice is a powerful and elegant high level data visualization system that is sufficient for most everyday graphics needs, yet flexible enough to be easily extended to handle demands of cutting edge research. Written by the author of the lattice system, this book describes it in considerable depth, beginning with the essentials and systematically delving into specific low levels details as necessary. No prior experience with lattice is required to read the book, although basic familiarity with R is assumed.

The mechanisms of action of the main classes of laxatives are widely described. The text contains illustrations that help to understand the origins of plant laxatives and the pharmacology of the most interesting ones. Doctors, pharmacists, herbalists, nurses and students will find this volume interesting and useful.
Language Learning Motivation and L2 Pragmatic Competence
It presents an original study that not only enriches our knowledge of the feasibility of modern technology in collecting large-scale data related to pragmatic competence but also eminently connects L2 pragmatics more closely with mainstream second language acquisition research by focusing on the role of motivation in pragmatic learning.
Language in our brain : The origins of a uniquely human capacity
Friederici describes the basic language functions and their brain basis; the language networks connecting different language-related brain regions; the brain basis of language acquisition during early childhood and when learning a second language, proposing a neurocognitive model of the ontogeny of language; and the evolution of language and underlying neural constraints. She finds that it is the information exchange between the relevant brain regions, supported by the white matter tract, that is the crucial factor in both language development and evolution.
Landscapes of Lifelong Learning Policies across Europe : Comparative Case Studies
This book explores different landscapes of Lifelong Learning policies (LLP), producing case-based examinations of their institutional, discursive, and relational dimensions. Across Europe, young people develop their life courses amidst diverse living conditions and are confronted with a variety of institutional and structural arrangements that impact on their opportunities in education and labour. Considering the relevance of LLP in shaping those opportunities, the chapters draw from multi-level, mixed-methods research and offer original insights on the interplay of discourses and governance patterns in the processes of policy-making and deliverance. The book yields noteworthy insights into the widely differing realities across the European landscape, and also into the diverging ways young people deal with and actively participate in LLP.
Landscape as Urbanism : A General Theory
Traces the roots of landscape as a form of urbanism from its origins in the Renaissance through the twentieth century. Growing out of progressive architectural culture and populist environmentalism, the concept was further informed by the nineteenth-century invention of landscape architecture as a "new art" charged with reconciling the design of the industrial city with its ecological and social conditions. In the late twentieth and early twenty-first centuries, as urban planning shifted from design to social science, and as urban design committed to neotraditional models of town planning, landscape urbanism emerged to fill a void at the heart of the contemporary urban project.
Lagrangian Transport in Geophysical Jets and Waves : The Dynamical Systems Approach
This book provides an accessible introduction to a new set of methods for the analysis of Lagrangian motion in geophysical flows. These methods were originally developed in the abstract mathematical setting of dynamical systems theory, through a geometric approach to differential equations. Despite the recent developments in this field and the existence of a substantial body of work on geophysical fluid problems in the dynamical systems and geophysical literature, this is the first introductory text that presents these methods in the context of geophysical fluid flow. The book is organized into seven chapters; the first introduces the geophysical context and the mathematical models of geophysical fluid flow that are explored in subsequent chapters. The second and third cover the simplest case of steady flow, develop basic mathematical concepts and definitions, and touch on some important topics from the classical theory of Hamiltonian systems. The fundamental elements and methods of Lagrangian transport analysis in time-dependent flows that are the main subject of the book are described in the fourth, fifth, and sixth chapters. The seventh chapter gives a brief survey of some of the rapidly evolving research in geophysical fluid dynamics that makes use of this new approach. Related supplementary material, including a glossary and an introduction to numerical methods, is given in the appendices.
