Book Description
Volume 1 of this work presents theory and methods to study the structure of condensed matter on different time scales. The authors cover the structure analysis by X-ray diffraction methods from crystalline to amorphous materials, from static-relaxed averaged structures to short-lived electronically excited structures, including detailed descriptions of the time-resolved experimental methods. Complementary, an overview of the theoretical description of condensed matter by static and time-dependent density functional theory is given, starting from the fundamental quantities that can be obtained by these methods through to the recent challenges in the description of time dependent phenomena such as optical excitations. Contents Static structural analysis of condensed matter: from single-crystal to amorphous DFT calculations of solids in the ground state TDDFT, excitations, and spectroscopy Time-resolved structural analysis: probing condensed matter in motion Ultrafast science

Book Description
Einstein's General Theory of Relativity leads to two remarkable predictions: first, that the ultimate destiny of many massive stars is to undergo gravitational collapse and to disappear from view, leaving behind a 'black hole' in space; and secondly, that there will exist singularities in space-time itself. These singularities are places where space-time begins or ends, and the presently known laws of physics break down. They will occur inside black holes, and in the past are what might be construed as the beginning of the universe. To show how these predictions arise, the authors discuss the General Theory of Relativity in the large. Starting with a precise formulation of the theory and an account of the necessary background of differential geometry, the significance of space-time curvature is discussed and the global properties of a number of exact solutions of Einstein's field equations are examined. The theory of the causal structure of a general space-time is developed, and is used to study black holes and to prove a number of theorems establishing the inevitability of singualarities under certain conditions. A discussion of the Cauchy problem for General Relativity is also included in this 1973 book.

Book Description
Fluid-structure interaction is a new theme of investigation in computational methods, covering many applications in both engineering and medical sciences. This book deals with various examples of interaction between a fluid and a structure, and each author presents, for the different problems involved, the method which is considered to be the most appropriate.

Book Description
While it is often assumed that behavioral development must be based upon both physical law and the biological principles of morphogenesis and selection, forging a link between these phenomena has remained an elusive goal. Now in Emergent Forms, psychologist Eugene C. Goldfield offers an exciting new theoretical framework--based, in part, on the concept of self-organization--that promises to aid researchers in their quest to discover the underlying origins and processes of behavioral development. Addressing the question of how familiar human functional acts--such as eating, walking, manipulating objects, and smiling--emerge during infancy, Goldfield proposes that during perceptually guided spontaneous activity a variety of biodynamic devices for doing different kinds of work are assembled and adapted to specific tasks. Throughout, the theory is examined in the context of development, and extended to atypical development and other domains, such as cognition and language. The author also addresses many long-standing issues in behavioral development, including the apparent disappearance of so-called primitive behaviors, the emergence of new skills, and the role of the caregiver in skill acquisition. The author concludes his work by discussing how the implications of this research can be applied to understanding abnormal development in children who are motor impaired. Interdisciplinary in scope and accessible to a broad range of readers, Emergent Forms will fascinate students and researchers of ecological, developmental, evolutionary, and cognitive psychology.

Book Description
Jakob Hohwy explores a new theory in neuroscience: the idea that the brain is essentially a hypothesis-testing mechanism that attempts to minimise the error of its predictions about sensory input. He explains the rich and multifaceted character of our conscious perception, and argues that the mind has a fragile, indirect relation to the world.

Book Description
Zusammenfassung: This highly interdisciplinary volume brings together a carefully curated set of case studies examining complex systems with multiple time scales (MTS) across a variety of fields: materials science, epidemiology, cell physiology, mathematics, climatology, energy transition planning, ecology, economics, sociology, history, and cultural studies. The book addresses the vast diversity of interacting processes underlying the behaviour of different complex systems, highlighting the multiplicity of characteristic time scales that are a common feature of many and showcases a rich variety of methodologies across disciplinary boundaries. Self-organizing, out-of-equilibrium, ever-evolving systems are ubiquitous in the natural and social world. Examples include the climate, ecosystems, living cells, epidemics, the human brain, and many socio-economic systems across history. Their dynamical behaviour poses great challenges in the pressing context of the climate crisis, since they may involve nonlinearities, feedback loops, and the emergence of spatial-temporal patterns, portrayed by resilience or instability, plasticity or rigidity; bifurcations, thresholds and tipping points; burst-in excitation or slow relaxation, and worlds of other asymptotic behaviour, hysteresis, and resistance to change. Chapters can be read individually by the reader with special interest in such behaviours of particular complex systems or in specific disciplinary perspectives. Read together, however, the case studies, opinion pieces, and meta-studies on MTS systems presented and analysed here combine to give the reader insights that are more than the sum of the book's individual chapters, as surprising similarities become apparent in seemingly disparate and unconnected systems. MTS systems call into question naïve perceptions of time and complexity, moving beyond conventional ways of description, analysis, understanding, modelling, numerical prediction, and prescription of the world around us. This edited collection presents new ways of forecasting, introduces new means of control, and - perhaps as the most demanding task - it singles out a sustainable description of an MTS system under observation, offering a more nuanced interpretation of the floods of quantitative data and images made available by high- and low-frequency measurement tools in our unprecedented era of information flows

Book Description
Volume 17 is the second in a special topic series devoted to modern techniques in protein NMR, under the Biological Magnetic Resonance series. Volume 16, with the subtitle Modern Techniques in Protein NMR , is the first in this series. These two volumes present some of the recent, significant advances in the biomolecular NMR field with emphasis on developments during the last five years. We are honored to have brought together in these volume some of the world s foremost experts who have provided broad leadership in advancing this field. Volume 16 contains - vances in two broad categories: I. Large Proteins, Complexes, and Membrane Proteins and II. Pulse Methods. Volume 17 contains major advances in: I. Com- tational Methods and II. Structure and Dynamics. The opening chapter of volume 17 starts with a consideration of some important aspects of modeling from spectroscopic and diffraction data by Wilfred van Gunsteren and his colleagues. The next two chapters deal with combined automated assignments and protein structure determination, an area of intense research in many laboratories since the traditional manual methods are often inadequate or laborious in handling large volumes of NMR data on large proteins. First, Werner Braun and his associates describe their experience with the NOAH/DIAMOD protocol developed in their laboratory.
