Nonlinearity in Living Systems: Theoretical and Practical Perspectives on Metrics of Physiological Signal Complexity


Book Description

The biological basis of physiological signals is incredibly complex. While many types of research certainly appreciate molecular, cellular and systems approach to unravel overall biological complexity, in the recent decades the interest for mathematical and computational characterization of structural and functional basis underlying biological phenomena gain wide popularity among scientists. Nowadays, we witnessed wide range applications of nonlinear quantitative analysis that produced measures such as fractal dimension, power-law scaling, Hurst exponent, Lyapunov exponent, approximate entropy, sample entropy, Lempel–Ziv complexity, as well as other metrics for predictions of onset and progression of many pathological conditions, especially in the central nervous systems (CNS). In this Research Topic, we seek to bring together the recent practical and theoretical advances in the development and application of nonlinear methods or narrower fractal-based methods for characterizing the complex physiological systems at multiple levels of the organization. We will discuss the use of various complexity measures and appropriate parameters for characterizing the variety of physiological signals up to the systems level. There are multiple aims in this topic. The recent advancement in the application of nonlinear methods for both normal and pathological physiological conditions is the first. The second aim is to emphasize the more recent successful attempt to apply these methods across animal species. Finally, a comprehensive understanding of advantages and disadvantages of each method, especially between its mathematical assumptions and real-world applicability, can help to find out what is at stake regarding the above aims and to direct us toward the more fruitful application of nonlinear measures and statistics in physiology and biology in general.

Perspectives of Mesoscopic Physics


Book Description

Professor Yoseph (Joe) Imry, an early initiator of mesoscopic physics, has been among the leaders in this field for several decades. This book contains articles by leading (theoretical and experimental) scientists working in nanoscience and in related fields. Most of the contributions, consisting both reviews of the state of the art and new results, summarize invited talks given at two conferences held in honor of Imry's 70th birthday: the 101st Statistical Mechanics Conference (Rutgers University, May 10?12, 2009), and Perspectives of Mesoscopic Physics (Weizmann Institute of Science, May 31?June 1, 2009). This book covers a broad range of active research in nanoscience, including topics like quantum interference, decoherence, electron correlations, nano superconductors and nano magnets, nonequilibrium and glassy behavior.




The Value of Systems and Complexity Sciences for Healthcare


Book Description

This visionary reframing of health and healthcare uses a complexity science approach to building healthcare systems that are accessible, effective, and prepared for change and challenges. Its holistic map for understanding the human organism emphasizes the interconnectedness of the individual’s physical, psychological, cognitive, and sociocultural functioning. Applications of this approach are described in primary, specialist, and emergency care and at the organizational and policy levels, from translating findings to practice, to problem solving and evaluation. In this model, the differences between disease and illness and treating illness and restoring health are not mere wordplay, but instead are robust concepts reflecting real-world issues and their solutions. Based on the Proceedings of the 1st International Conference of Systems and Complexity for Healthcare, topics covered include: • Coping with complexity and uncertainty: insights from studying epidemiology in family medicine • Anticipation in complex systems: potential implications for improving safety and quality in healthcare • Monitoring variability and complexity at the bedside • Viewing mental health through the lens of complexity science • Ethical complexities in systems healthcare: what care and for whom? • The value of systems and complexity thinking to enable change in adaptive healthcare organizations supported by informatics • If the facts don’t fit the theory, change the theory: implications for health system reform The Value of Systems and Complexity Sciences for Healthcare will interest and inspire health and disease researchers, health professionals, health care planners, health system financiers, health system administrators, health services administrators, health professional educators, and, last but not least, current and future patients.




Recovery and Major Mental Disorders


Book Description

The book provides a clear and comprehensive description of both personal and clinical recovery in severe mental disorders, including schizophrenia and related disorders, and mood disorders such as major depression and bipolar disorders. Divided into two main parts: recovery in schizophrenia and related disorders, and recovery in mood disorders, it offers a broad overview of the factors associated with better or worse outcomes in terms of recovery, as well as the rates (how many people affected by mental disorders may gain recovery), and the time course (how long people affected by mental disorders take to recover) of recovery. It also discusses in detail the pharmacological and psychosocial interventions that can be considered recovery-oriented. Covering the main aspects of recovery in major mental disorders, the book is intended for professionals, scholars, students and anyone interested in mental health.




The Non-Linear Field Theories of Mechanics


Book Description

This third edition includes the corrections made by the late C. Truesdell in his personal copy. It is annotated by S. Antman who describes the monograph`s genesis and the impact it has made on the modern development of mechanics. Originally published as Volume III/3 of the famous Encyclopedia of Physics in 1965, this book describes and summarizes "everything that was both known and worth knowing in the field at the time." It also has greatly contributed to the unification and standardization of the concepts, terms and notations in the field.
