Book Description
From a biomedical engineering perspective, this book takes an analytic, quantitative approach to describing the basic components of physiological regulators and control systems (PRCs). In Endogenous and Exogenous Regulation and Control of Physiological Systems, the author provides grounding in the classical methods of designing linear and nonlinear systems. He also offers state-of-the-art material on the potential of PRCs to treat immune system ailments, most notably AIDS and cancer. The book focuses on certain "wet" physiological regulators, such as those using endocrine hormones as parametric control substances. Endogenous and Exogenous Regulation and Control of Physiological Systems includes simulations that illustrate model validations and the putative control of cancer and HIV proliferation. It explores novel, untried immunotherapies on the cutting-edge of PRC treatment and explores the latest technologies.

Book Description
This book aims at presenting biologists and clinicians with a compact description of the physiological manifestations of sleep that are significant from the viewpoint of the principle of homeostasis. In the jargon of the physiological literature, the word ?homeostasis?, introduced by W.B. Cannon (1926), refers to the existence of a constant state of extracellular body fluids with regard to their physical and chemical properties. Since normal cell function depends on the constancy of such fluids, in multicellular animals there are many regulatory mechanisms under the control of the central nervous system that act to maintain the constancy of the internal environment.The experimental study of homeostasis in wakefulness already revealed the nature and complexity of the underlying physiological mechanisms. Many of these regulatory mechanisms trigger compensatory changes according to the principle of negative feedback. In contrast, the control of homeostasis across sleep states is still an issue under debate concerning its physiological persistence and significance. The author's aim is to find the specific mechanistic proofs of the actual consistency or inconsistency of the principle in different states of sleep. In this respect, there are several interacting physiological functions that ought to be examined across the sleep states. The selection of the most significant experimental data is carried out with a view to present a simple but not simplistic approach to the issue.The book brings forth the evidence that the systemic homeostatic regulation of many physiological variables underlying cellular life is not active in a particular state of the ultradian sleep cycle in mammals. It also shows the theoretical and functional importance of the principle of homeostasis, as a criterion of the systemic characterisation of the integrative control of physiological functions by the central nervous system during sleep in mammals.

Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Book Description
Over the past century, educational psychologists and researchers have posited many theories to explain how individuals learn, i.e. how they acquire, organize and deploy knowledge and skills. The 20th century can be considered the century of psychology on learning and related fields of interest (such as motivation, cognition, metacognition etc.) and it is fascinating to see the various mainstreams of learning, remembered and forgotten over the 20th century and note that basic assumptions of early theories survived several paradigm shifts of psychology and epistemology. Beyond folk psychology and its naïve theories of learning, psychological learning theories can be grouped into some basic categories, such as behaviorist learning theories, connectionist learning theories, cognitive learning theories, constructivist learning theories, and social learning theories. Learning theories are not limited to psychology and related fields of interest but rather we can find the topic of learning in various disciplines, such as philosophy and epistemology, education, information science, biology, and – as a result of the emergence of computer technologies – especially also in the field of computer sciences and artificial intelligence. As a consequence, machine learning struck a chord in the 1980s and became an important field of the learning sciences in general. As the learning sciences became more specialized and complex, the various fields of interest were widely spread and separated from each other; as a consequence, even presently, there is no comprehensive overview of the sciences of learning or the central theoretical concepts and vocabulary on which researchers rely. The Encyclopedia of the Sciences of Learning provides an up-to-date, broad and authoritative coverage of the specific terms mostly used in the sciences of learning and its related fields, including relevant areas of instruction, pedagogy, cognitive sciences, and especially machine learning and knowledge engineering. This modern compendium will be an indispensable source of information for scientists, educators, engineers, and technical staff active in all fields of learning. More specifically, the Encyclopedia provides fast access to the most relevant theoretical terms provides up-to-date, broad and authoritative coverage of the most important theories within the various fields of the learning sciences and adjacent sciences and communication technologies; supplies clear and precise explanations of the theoretical terms, cross-references to related entries and up-to-date references to important research and publications. The Encyclopedia also contains biographical entries of individuals who have substantially contributed to the sciences of learning; the entries are written by a distinguished panel of researchers in the various fields of the learning sciences.

Book Description
The concept of homeostasis, the maintenance of the internal physiological environment of an organism within tolerable limits, is well established in medicine and physiology. In contrast, allostasis is a relatively new idea of 'viability through change'. With allostatic regulation by cephalic involvement, the body adapts to potentially diverse and dangerous situations through the activation of neural, hormonal, or immunological mechanisms. Allostasis explains how regulatory events maintain organismic viability, or not, in diverse contexts with varying set points of bodily needs and competing motivations. This 2005 book introduces the concept of allostasis and sets it alongside traditional views of homeostasis. It addresses basic regulatory systems and examines the behavior of bodily regulation under duress. The basic concepts of physiological homeostasis are integrated with disorders like depression, stress, anxiety and addiction. It will therefore appeal to graduate students, medical students and researchers working in physiology, epidemiology, endocrinology, neuroendocrinology, neuroscience, and psychology.
