Book Synopsis Role of Nonlinear Dynamics in Endocrine Feedback by : Chinmoy K. Bose
Download or read book Role of Nonlinear Dynamics in Endocrine Feedback written by Chinmoy K. Bose and published by Nova Biomedical Books. This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endocrine feedback system may not be appreciated by conventional hormone level estimation at a single point of time. Our body also needs to be looked at as a dynamical system, a dissipative structure. Specifically, the information processing at the neuroendocrine level must be guided by a science that is not random but deterministic. For sustenance of life body environ must always (at the present moment) balance itself delicately and relentlessly. In this dynamical system, feedback control will essentially be mathematical control that has to be understood in the light of physical control theory. Whatever goes around inside the body must be originating from chemical reactions, but factors controlling the nature and rate and limit of those reactions are multi-relation oriented. The outcome of such relationship is not limited to linear reactions but dependent on some "non-material entity", like balancing while cycling or walking on a rope. This non-material entity is described as "feedback" relationship. This book tries to elucidate how and why such kind of relationship must be understood in order to know this reportedly simple subject of endocrine feedback.
Book Synopsis Feedback Control in Systems Biology by : Carlo Cosentino
Download or read book Feedback Control in Systems Biology written by Carlo Cosentino and published by CRC Press. This book was released on 2011-10-17 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Like engineering systems, biological systems must also operate effectively in the presence of internal and external uncertainty—such as genetic mutations or temperature changes, for example. It is not surprising, then, that evolution has resulted in the widespread use of feedback, and research in systems biology over the past decade has shown that feedback control systems are widely found in biology. As an increasing number of researchers in the life sciences become interested in control-theoretic ideas such as feedback, stability, noise and disturbance attenuation, and robustness, there is a need for a text that explains feedback control as it applies to biological systems. Written by established researchers in both control engineering and systems biology, Feedback Control in Systems Biology explains how feedback control concepts can be applied to systems biology. Filling the need for a text on control theory for systems biologists, it provides an overview of relevant ideas and methods from control engineering and illustrates their application to the analysis of biological systems with case studies in cellular and molecular biology. Control Theory for Systems Biologists The book focuses on the fundamental concepts used to analyze the effects of feedback in biological control systems, rather than the control system design methods that form the core of most control textbooks. In addition, the authors do not assume that readers are familiar with control theory. They focus on "control applications" such as metabolic and gene-regulatory networks rather than aircraft, robots, or engines, and on mathematical models derived from classical reaction kinetics rather than classical mechanics. Another significant feature of the book is that it discusses nonlinear systems, an understanding of which is crucial for systems biologists because of the highly nonlinear nature of biological systems. The authors cover tools and techniques for the analysis of linear and nonlinear systems; negative and positive feedback; robustness analysis methods; techniques for the reverse-engineering of biological interaction networks; and the analysis of stochastic biological control systems. They also identify new research directions for control theory inspired by the dynamic characteristics of biological systems. A valuable reference for researchers, this text offers a sound starting point for scientists entering this fascinating and rapidly developing field.
Book Synopsis Practical Numerical Algorithms for Chaotic Systems by : Thomas S. Parker
Download or read book Practical Numerical Algorithms for Chaotic Systems written by Thomas S. Parker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the basic tenets of science is that deterministic systems are completely predictable-given the initial condition and the equations describing a system, the behavior of the system can be predicted 1 for all time. The discovery of chaotic systems has eliminated this viewpoint. Simply put, a chaotic system is a deterministic system that exhibits random behavior. Though identified as a robust phenomenon only twenty years ago, chaos has almost certainly been encountered by scientists and engi neers many times during the last century only to be dismissed as physical noise. Chaos is such a wide-spread phenomenon that it has now been reported in virtually every scientific discipline: astronomy, biology, biophysics, chemistry, engineering, geology, mathematics, medicine, meteorology, plasmas, physics, and even the social sci ences. It is no coincidence that during the same two decades in which chaos has grown into an independent field of research, computers have permeated society. It is, in fact, the wide availability of inex pensive computing power that has spurred much of the research in chaotic dynamics. The reason is simple: the computer can calculate a solution of a nonlinear system. This is no small feat. Unlike lin ear systems, where closed-form solutions can be written in terms of the system's eigenvalues and eigenvectors, few nonlinear systems and virtually no chaotic systems possess closed-form solutions.
Book Synopsis Stability and Oscillations of Nonlinear Pulse-Modulated Systems by : Arkadii Kh. Gelig
Download or read book Stability and Oscillations of Nonlinear Pulse-Modulated Systems written by Arkadii Kh. Gelig and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are two main fields of application of pulse-modulated sys tems, communications and control. Communication is not a subject of our concern in this book. Controlling by a pulse-modulated feed attracted our efforts. The peculiarity of this book is that all back the sampled-data systems are considered in continuous time, so no discrete time schemes are presented. And finally, we pay a little at tention to pulse-amplitude modulation which was treated in a vast number of publications. The primary fields of our interest are pulse width, pulse-frequency, and pulse-phase modulated control systems. The study of such systems meets with substantial difficulties. An engineer, who embarks on theoretical investigations of a pulse-mo dulated control, is often embarrassed by the sophisticated mathe matical tools he needs to know. When a mathematician, who looks for practical applications of his mathematical machinery, meets with these systems, he faces a lot of of complicated technical schemes and terms. Probably this is the reason why publications on pulse modu lation are seldom in scientific journals. As for books on this subject (save on amplitude modulation), the significant part of them is in Russian and hardly available for a non-Russian reader.

Book Synopsis Analysis of Physiological Systems by : Vasilis Marmarelis
Download or read book Analysis of Physiological Systems written by Vasilis Marmarelis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: In studying physiological systems bioscientists are continually faced with the problem of providing descriptions of cause-effect relationships. This task is usually carried out through the performance of stimulus-response experiments. In the past, the design of such experiments has been ad hoc, incomplete, and certainly inefficient. Worse yet, bioscientists have failed to take advantage of advances in fields directly related to their problems (specifically, advances in the area of systems analysis). The raison d'etre of this book is to rectify this deficiency by providing the physiologist with methodological tools that will be useful to him or her in everyday labora tory encounters with physiological systems. The book was written so that it would be practical, useful, and up-to date. With this in mind, parts of it give step-by-step descriptions of in the laboratory. It is hoped that this systematic procedures to be followed will increase the usefulness of the book to the average research physiologist and, perhaps, reduce the need for in-depth knowledge of some of the associated mathematics. Even though the material deals with state-of-the art techniques in systems and signal analysis, the mathematical level has been kept low so as to be comprehensible to the average physiologist with no extensive training in mathematics. To this end, mathematical rigor is often sacrificed readily to intuitive simple arguments.

Book Synopsis Applications of Nonlinear Dynamics To Developmental Process Modeling by : Karl M. Newell
Download or read book Applications of Nonlinear Dynamics To Developmental Process Modeling written by Karl M. Newell and published by Psychology Press. This book was released on 2014-03-05 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been an increasing interest in the application of dynamical systems to the study of development over the last decade. The explosion of the dynamical systems framework in the physical and biological sciences has opened the door to a new Zeitgeist for studying development. This appeal to dynamical systems by developmentalists is natural given the intuitive links between the established fundamental problems of development and the conceptual and operational scope of nonlinear dynamical systems. This promise of a new approach and framework within which to study development has led to some progress in recent years but also a growing appreciation of the difficulty of both fully examining the new metaphor and realizing its potential. Divided into 4 parts, this book is a result of a recent conference on dynamical systems and development held at Pennsylvania State University. The first 3 parts focus on the content domains of development that have given most theoretical and empirical attention to the potential applications of dynamical systems--physical growth and movement, cognition, and communication. These parts show that a range of nonlinear models have been applied to a host of developmental phenomena. Part 4 highlights two particular methodological issues that hold important implications for the modeling of developmental phenomena with dynamical systems techniques.

Available in PDF, EPUB and Kindle. Book excerpt: Vertebrate Endocrinology represents more than just a treatment of the endocrine system-it integrates hormones with other chemical bioregulatory agents not classically included with the endocrine system. It provides a complete overview of the endocrine system of vertebrates by first emphasizing the mammalian system as the basis of most terminology and understanding of endocrine mechanisms and then applies that to non-mammals. The serious reader will gain both an understanding of the intricate relationships among all of the body systems and their regulation by hormones and other bioregulators, but also a sense of their development through evolutionary time as well as the roles of hormones at different stages of an animal's life cycle. - Includes new full color format includes over 450 full color, completely redrawn image - Features a companion web site hosting all images from the book as PPT slides and .jpeg files - Presents completedly updated and revitalized content with new chapters, such as Endocrine Disrupters and Behavioral Endocrinology - Offers new clinical correlation vignettes throughout
Book Synopsis Approaching Complex Diseases by : Mariano Bizzarri
Download or read book Approaching Complex Diseases written by Mariano Bizzarri and published by Springer Nature. This book was released on 2020-04-17 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume – for pharmacologists, systems biologists, philosophers and historians of medicine – points to investigate new avenues in pharmacology research, by providing a full assessment of the premises underlying a radical shift in the pharmacology paradigm. The pharmaceutical industry is currently facing unparalleled challenges in developing innovative drugs. While drug-developing scientists in the 1990s mostly welcomed the transformation into a target-based approach, two decades of experience shows that this model is failing to boost both drug discovery and efficiency. Selected targets were often not druggable and with poor disease linkage, leading to either high toxicity or poor efficacy. Therefore, a profound rethinking of the current paradigm is needed. Advances in systems biology are revealing a phenotypic robustness and a network structure that strongly suggest that exquisitely selective compounds, compared with multitarget drugs, may exhibit lower than desired clinical efficacy. This appreciation of the role of polypharmacology has significant implications for tackling the two major sources of attrition in drug development, efficacy and toxicity. Integrating network biology and polypharmacology holds the promise of expanding the current opportunity space for druggable targets.

Book Synopsis Model Predictive Control in the Process Industry by : Eduardo F. Camacho
Download or read book Model Predictive Control in the Process Industry written by Eduardo F. Camacho and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Model Predictive Control is an important technique used in the process control industries. It has developed considerably in the last few years, because it is the most general way of posing the process control problem in the time domain. The Model Predictive Control formulation integrates optimal control, stochastic control, control of processes with dead time, multivariable control and future references. The finite control horizon makes it possible to handle constraints and non linear processes in general which are frequently found in industry. Focusing on implementation issues for Model Predictive Controllers in industry, it fills the gap between the empirical way practitioners use control algorithms and the sometimes abstractly formulated techniques developed by researchers. The text is firmly based on material from lectures given to senior undergraduate and graduate students and articles written by the authors.
Book Synopsis The Quest for Fitness by : Mark Michaels
Download or read book The Quest for Fitness written by Mark Michaels and published by iUniverse. This book was released on 2000-12 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Quest for Fitness: A rational exploration into the new science of organizations follows the tradition of Frederick Taylor and W. Edwards Deming by rationally applying scientific principles and processes to understanding the nature of organization. The book recognizes that the environment has changed drastically since Taylor applied Newtonian principles to describe the industrial organization. The synthesis forces the reader to change his/her view from considering how an organization can be created to take control of its environment to how one can be created to survive over time in a changing environment. The Quest for Fitness leaves the reader with a vision of organizations as complex adaptive organisms striving to stay fit on an ever-changing landscape. There is an ongoing search to optimize one’s position in an uncharted wilderness. Survival is not dependent upon the strongest but upon the ability to adapt as the landscape changes. The leaders of such organizations are no longer commanders, but explorers, who create network infrastructures enabling information to be received, integrated, and shared throughout the organization so that individual parts can best respond to immediate conditions, without the total system flying apart.
