Available in PDF, EPUB and Kindle. Book excerpt: This award-winning thesis investigates the mechanisms underlying cardiac arrhythmia development and termination from an entirely new perspective. By viewing the heart as a complex system, the author uses theoretical tools from nonlinear dynamics combined with numerical simulations and experiments to achieve insights into the relationship between its structure and dynamics, thereby paving the way towards innovative low-energy defibrillation strategies. The work tackles, among other things: the effect of substrate heterogeneity on the spatial-temporal dynamics of cardiac arrhythmias and ways in which weak pulsed electric fields can be used to control these dynamics in heterogeneous cardiac tissue. The long-term vision of this research is to replace the current strategy of applying painful and sometimes tissue damaging electric shock – currently the only reliable way to terminate life-threatening fibrillation – by a more subtle but equally effective intervention. The book maps out a number of promising research directions for biophysicists and medical researchers working on the origins and treatment of cardiac arrhythmias.

Available in PDF, EPUB and Kindle. Book excerpt: Cardiac Dynamics is the name of a relatively young field of study, born from the fruitful interaction between branches of two different disciplines: medicine and physics. "Dynamics" is the branch of physics which deals with the action of forces on bodies or particles in motion or at rest. "Cardiac" relates to the clinical field of cardiology but also to cardiophysiology, both of which are specialized branches of medicine. Narrower than the well established field of Hemodynamics, Cardiac Dynamics is restricted to dynamic phenomena occurring in and around the heart. The mathematical treatment of such phenomena, however, is vastly more complex because of the intricate nature of the mechanisms involved in the cardiac action. Thus, whereas hemodynamics is concerned with predominantly passive (visco-) elastic structures - vessels - containing time-variant flow of viscous flui- blood -, the mechanical study of the heart requires additional con siderations such as: active elastic components representing the contractile mechanism of cardiac muscle, complex geometry and fiber structure in the myocardial wall, autoregulatory mechanisms, and intricate flow patterns associated with valve motion. Viewed in this light it is not surprising that attempts to describe ventricular pump function and to quantify contractile performance have not reached the level of sophistication which is common in e. g. arterial hemodynamics. For the same reason, many of the often simplified approaches to describe ventricular mechanics failed to stand up to more rigorous theoretical, experimental or clinical testing.

Download or read book Cytochrome Complexes Evolution Structures Energy Transduction and Signaling written by William A. Cramer and published by Springer. This book was released on 2016-06-14 with total page 763 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Introduction that describes the origin of cytochrome notation also connects to the history of the field, focusing on research in England in the pre-World War II era. The start of the modern era of studies on structure-function of cytochromes and energy-transducing membrane proteins was marked by the 1988 Nobel Prize in Chemistry, given to J. Deisenhofer, H. Michel, and R. Huber for determination of the crystal structure of the bacterial photosynthetic reaction center. An ab initio logic of presentation in the book discusses the evolution of cytochromes and hemes, followed by theoretical perspectives on electron transfer in proteins and specifically in cytochromes. There is an extensive description of the molecular structures of cytochromes and cytochrome complexes from eukaryotic and prokaryotic sources, bacterial, plant and animal. The presentation of atomic structure information has a major role in these discussions, and makes an important contribution to the broad field of membrane protein structure-function.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years there has been a growth in interest in studying the heart from the perspective of the physical sciences: mechanics, fluid flow, electromechanics. This volume is the result of a workshop held in July 1989 at the Institute for Nonlinear Sciences at the University of California at San Diego that brought together scientists and clinicians with graduate students and postdoctoral fellows who shared an interest in the heart. The chapters were prepared by the invited speakers as didactic reviews of their subjects but also include the structure, mechanical properties, and function of the heart and the myocardium, electrical activity of the heart and myocardium, and mathematical models of heart function.

Book excerpt: Physics at the beginning of the twenty-first century has reached new levels of accomplishment and impact in a society and nation that are changing rapidly. Accomplishments have led us into the information age and fueled broad technological and economic development. The pace of discovery is quickening and stronger links with other fields such as the biological sciences are being developed. The intellectual reach has never been greater, and the questions being asked are more ambitious than ever before. Physics in a New Era is the final report of the NRC's six-volume decadal physics survey. The book reviews the frontiers of physics research, examines the role of physics in our society, and makes recommendations designed to strengthen physics and its ability to serve important needs such as national security, the economy, information technology, and education.

Available in PDF, EPUB and Kindle. Book excerpt: I know that most men, including those at ease with the problems of the greatest complexity, can seldom accept even the simplest and most obvious truth if it be such as would oblige them to admit the falsity of conclusions which they have delighted in explaining to colleagues, which they have proudly taught to others, and which they have woven, thread by thread, into the fabric of their lives. Joseph Ford quoting Tolstoy (Gleick, 1987) We are used to thinking that natural objects have a certain form and that this form is determined by a characteristic scale. If we magnify the object beyond this scale, no new features are revealed. To correctly measure the properties of the object, such as length, area, or volume, we measure it at a resolution finer than the characteristic scale of the object. We expect that the value we measure has a unique value for the object. This simple idea is the basis of the calculus, Euclidean geometry, and the theory of measurement. However, Mandelbrot (1977, 1983) brought to the world's attention that many natural objects simply do not have this preconceived form. Many of the structures in space and processes in time of living things have a very different form. Living things have structures in space and fluctuations in time that cannot be characterized by one spatial or temporal scale. They extend over many spatial or temporal scales.
