Atomic Radiative Processes provides a unified treatment of the theory of atomic radiative processes. Fourier transforms are used to obtain solutions of time-dependent Schrödinger equations, and coupled differential equations are transformed to coupled linear equations that in most cases can be readily solved. This book consists of nine chapters and begins with an overview of some of the properties of the classical field and its interaction with particles, focusing on those aspects needed for a better understanding of quantum theory. The Hamiltonian formalism is used to quantize the field, and the density of states of the radiation field is considered. The following chapters focus on a few Fourier transform techniques and their application to such areas as coherence properties of the field and amplitude and intensity correlations; the theory of angular momentum; the properties of irreducible tensors; quantization of the radiation field; and photon states. The interaction of a two-level atom with single modes of the radiation field is also discussed, along with spontaneous emission and decay processes; the evolution of coupled atomic states; the frequency distribution of emitted radiation; and radiative excitation and fluorescence. This monograph is intended for students and researchers in pure and applied physics.
Since 1984, the year of the publication of its first edition, the famous “Blue Guide” has been the international reference for paediatricians and neuropaediatricians with regard to epileptic syndromes in infants, children and adolescents. This 6th edition reviews some of the most noteworthy developments in the field, particularly in epileptic syndromes, but also focuses on the genetic aspects of the syndromes and their development. Progress brought about by advances in neuroimaging is also discussed in addition to specific etiologies such as parasitic diseases and immune and autoimmune diseases. The different backgrounds of the contributors - coordinators and authors – ensure that the book’s longstanding reputation for objectivity and seriousness, built over almost 35 years, remain well-deserved. This book written by the current leading specialists is recognized worldwide as the international reference in epilepsy.
Intended for cell biologists, biophysicists, biochemists, molecular biologists, physiologists, researchers in hemostatsis and thrombosis and pathologists, this book provides an insight into cell adhesion from three interdisciplinary perspectives: fundamental facts of adhesion; molecular biochemistry of adhesion and physiological aspects. It summarizes the basic aspects of surfaces in general and describes the theoretical and experimental tools necessary to investigate cell adhesion, including the basic biochemistry and molecular biology of adhesion. The book offers concise treatment of individual topics, features current material, and provides key references as a guide to further study.

It will be of immense value to a wide variety of helping professionals and carers, including social workers, psychologists, doctors, voluntary counsellors, and all those whose work brings them into contact with disaster victims.
Free Imagination argues that the brain's capacity to imagine is the fundamental basis of human Free Will. Laws of physics need not apply in our internal simulations, so virtually anything is possible there. And since some of our actions can follow from that which we imagine, especially from processes of deliberation that involve imagining possible scenarios and outcomes, our actions inherit the freedom of our imaginings. The creative power of the human imagination may have evolved as a consequence of the demodularization of neural circuitry associated with volitional attentional operations over operands downloadable into a mental workspace where, virtually, anything could be combined with anything else. This new cognitive architecture gave rise to the danger of psychosis. Our schizotypal form of imagination, arising from the promiscuous, generative and iterative combination of disencapsulated operators and operands in a mental workspace, may have evolved only in humans by exapting from existing motoric and other operations involved in volitional hand dexterity to a domain of premotoric simulation. What we imagine into existence can be used for good or evil. Imagination is therefore our greatest tool and weapon. When applied to ourselves, it allows us the possibility of reimagining and then transforming ourselves in light of second-order desires. This gives us the ability to choose to become a new kind of chooser in the future. Other animals lack this second-order Free Will; although they can do otherwise, they cannot want to become otherwise than they are, making them amoral. This book explores the idea that because humans, in contrast, have second-order Free Will, they can be moral or immoral.
Translational research connects science and clinical medicine from "the bench to the bedside." In Sleep, Epilepsies and Cognitive Impairment, the authors look back from the bedside to the brain function underlying clinical symptoms and reveal mechanisms explored by contemporary neuroimaging and signal analysis in the overlapping fields of sleep and epilepsy. This book will help the reader to see epilepsy from a new viewpoint. The common pathophysiology binding together the diverse manifestations of epilepsies is the exaggeration of plastic functions of the brain involving the hippocampus, the non-specific thalamocortical system and the perisylvian cognitive network. Epileptic derailment seems to be the price for the latest achievements of the mammal and human brain; namely the highly developed ability to change and learn. The contemporary results of sleep research provide new viewpoints to explain why sleep and epilepsy are bedfellows. Converging evidence supports the concept that one of the most important biological roles of NREM sleep is the renewal of synaptic balance ensuring learning ability from one day to the next and consolidation of new memories. Epilepsy and NREM sleep use overlapping structures and functions, therefore epilepsy beginning in early childhood may interfere with sleep plastic functions. NREM sleep, which affects original learning and memory, may become the hidden source of chronic cognitive impairment when epilepsy occurs during sleep and blocks the plastic processes. Sleep, Epilepsies and Cognitive Impairment abandons the academic classification of epilepsy by following the system epilepsy concept, binding major epilepsies with structures and functions of physiological brain systems. It tries to show within this system the close interrelationship between sleep, epilepsy and cognition. Neuroscientists, clinical epileptologists and neurologists interested in brain processes underlying brain plasticity, sleep and epilepsy will find this book thought provoking. It offers good "brain-gymnastics" for reconsidering the ideas on epilepsy. - It provides contemporary knowledge about the neurophysiological and functional anatomical background of major epilepsies - Treats major epilepsies as system epilepsies of brain networks - Reveals the interrelationship of sleep, epilepsy and cognitive impairment showing how epileptic manifestations became facilitated in NREM sleep and interferes with sleep plastic functions
