Group Motion--an improvisational dance performance practice--represents fifty years of co-creation by the authors, with the participation of thousands of dancers, musicians, videographers and others around the globe. Informed by Mary Wigman's expressionist dance and other contemporary dance and theater traditions, Group Motion has brought dance not only to stages worldwide, but also to public parks, prisons and airports. Part memoir, part guidebook, part philosophy of art treatise, this book provides step-by-step guidance to dozens of improvisational structures or games for dance professionals, theater artists, musicians and other performers who use movement for creative expression.
The two most important developments in nuclear physics were the shell model and the collective model. The former gives the formal framework for a description of nuclei in terms of interacting neutrons and protons. The latter provides a very physical but phenomenological framework for interpreting the observed properties of nuclei. A third approach, based on variational and mean-field methods, brings these two perspectives together in terms of the so-called unified models. Together, these three approaches provide the foundations on which nuclear physics is based. They need to be understood by everyone practicing or teaching nuclear physics, and all those who wish to gain an understanding of the foundations of the models and their relationships to microscopic theory as given by recent developments in terms of dynamical symmetries. This book provides a simple presentation of the models and theory of nuclear collective structure, with an emphasis on the physical content and the ways they are used to interpret data. Part 1 presents the basic phenomenological collective vibrational and rotational models as introduced by Bohr and Mottelson and their many colleagues. It also describes the extensions of these models to parallel unified models in which neutrons and protons move in a mean-field with collective degrees of freedom. Part 2 presents the predominant theories used to describe the collective properties of nuclei in terms of interacting nucleons. These theories, which are shared with other many-body systems, are shown to emerge naturally from the unified models of Part 1.
Focuses on behaviour monitoring and interpretation with regard to two main areas of focus: investigation of motion patterns and ambient assisted living. This book presents contributions on research in both these areas. It includes chapters discussing developments in monitoring and representing behaviours, with a focus on movement-based behaviour.
Self-propelled objects (particles, droplets) are autonomous agents that can convert energy from the environment into motion. These motions include nonlinear behaviour such as oscillations, synchronization, bifurcation, and pattern formation. In recent years, there has been much interest in self-propelled objects for their potential role in mass transport or their use as carriers in confined spaces. An improved understanding of self-organized motion has even allowed researchers to design objects for specific motion. This book gives an overview of the principles of self-propelled motion in chemical objects (particles, droplets) far from their thermodynamic equilibrium, at various spatial scales. Theoretical aspects, the characteristics of the motion and the design procedures of such systems are discussed from the viewpoint of nonlinear dynamics and examples of applications for these nonlinear systems are provided. This book is suitable for researchers and graduate students interested in physical and theoretical chemistry as well as soft matter.
Beginning at an introductory level, this text presents a thorough treatment of plasma physics, including an extensive discussion of its applications in thermonuclear fusion research. A novel feature of this book is its comprehensive description of the various concepts and formulas widely used in fusion theory based on the fundamental equations of the plasma fluid. The physics of fusion plasmas is explained mainly in relation to recent progress in tokamak research, but other plasma confinement schemes, such as stellarators and inertial confinement, are also described. The unique and systematic presentation will help readers to understand the overall structure of plasma theory and will facilitate access to more advanced literature on special topics.
This edited volume collects six surveys that present state-of-the-art results on modeling, qualitative analysis, and simulation of active matter, focusing on specific applications in the natural sciences. Following the previously published Active Particles volumes, these chapters are written by leading experts in the field and reflect the diversity of subject matter in theory and applications within an interdisciplinary framework. Topics covered include: Variability and heterogeneity in natural swarms Multiscale aspects of the dynamics of human crowds Mathematical modeling of cell collective motion triggered by self-generated gradients Clustering dynamics on graphs Random Batch Methods for classical and quantum interacting particle systems The consensus-based global optimization algorithm and its recent variants Mathematicians and other members of the scientific community interested in active matter and its many applications will find this volume to be a timely, authoritative, and valuable resource.
Progress in Nuclear Physics: Volume 6 is a collection of scientific papers in the field of experimental and theoretical physics. The compendium contains research papers covering a wide and diverse range of subjects in various areas of physics. The book provides contributions that discuss the methods for measuring atomic masses; the preparation of pure or enriched isotopes through electromagnetic separators; the study of nuclear moments; the spectroscopy of mesonic atoms; and parity nonconservation in weak interactions. Theoretical and experimental physicists will find this book very insightful.
This thesis focuses on experimental studies on collective motion using swimming bacteria as model active-matter systems. It offers comprehensive reviews of state-of-the-art theories and experiments on collective motion from the viewpoint of nonequilibrium statistical physics. The author presents his experimental studies on two major classes of collective motion that had been well studied theoretically. Firstly, swimming filamentous bacteria in a thin fluid layer are shown to exhibit true, long-range orientational order and anomalously strong giant density fluctuations, which are considered universal and landmark signatures of collective motion by many numerical and theoretical works but have never been observed in real systems. Secondly, chaotic bacterial turbulence in a three-dimensional dense suspension without any long-range order as described in the first half is demonstrated to be capable of achieving antiferromagnetic vortex order by imposing a small number of constraints with appropriate periodicity. The experimental results presented significantly advance our fundamental understanding of order and fluctuations in collective motion of motile elements and their future applications.
Band Structure and Nuclear Dynamics contains a compilation of papers that were presented at the International Conference on Band Structure and Nuclear Dynamics. This volume examines the relationships between phenomenological models, such as the VMI, IBA and Bohr-Mottelson models, and it discusses the attempts to provide microscopic foundations for these models. It also reviews other boson expansion techniques. The book includes the experiments on rotating nuclei, which indicate that different phases, shapes, and angular momentum coupling schemes are suitable for different spin regions and different bands; and the HFB-cranking model, which provides a theoretical framework for the interpretation of these rotational phenomena. This volume is subdivided into six parts. The first part focuses on phenomenological collective models, including the theory of nuclear collective motion, VMI and other related models, and the boson-fermion model. Part two discusses strongly deformed nuclei, including the band structure and the structure of the collective bands in it from a microscopic point of view. This part also presents the Hartree-Fock-Bogoliubov theory and the application of the cranking model to Yb bands and band crossings. The third part focuses on transitional nuclei and covers IBA models, symmetric rotor interpretation of interpretation of transitional nuclei, electromagnetic properties of excited bands, and boson models. Part four describes the very high spin states and its Nilsson-Strutinsky model and self-consistent theory. Part five includes three special topics and Part six concludes by providing topics for a round-table discussion.
