The Ontology of Physics for Biology: Semantic Modeling of Multiscale, Multidomain Physiological Systems

by Daniel L. Cook John H. Gennari Maxwell L. Neal

This book introduces semantic representations of multiscale, multidomain physiological systems that link to qualitative reasoning and to quantitative analysis of biophysical processes in health and disease. Two major public health problems, diabetes and hypertension, serve as use-cases to illustrate the depth and rigor of such representations for logical inference and quantitative analysis. Central to this approach is the Ontology of Physics for Biology (OPB) that formally represents the foundations of classical physics and engineering system dynamics that are the basis for our understanding of biomedical entities, processes, and functional relationships. Furthermore, we introduce OPB-based software for annotating and abstracting available biosimulation models for reuse, recombination, and for archiving of physics-based biomedical knowledge. We have formalized and leveraged physics-based biological knowledge as a working view of physiology and biophysics from three distinct perspectives: (1) biologists and biomedical investigators, (2) biophysicists and bioengineers, and (3) biomedical ontologists and informaticists. We present a logical and intuitive semantics of classical physics as a tool for mediating and translating biophysical knowledge among biomedical domains. Daniel L. Cook, MD, PhD John H.

Optical Methods for Managing the Diabetic Foot

by Gennadi Saiko Robert L. Bartlett Jose L. Ramirez-GarciaLuna

This book discusses optical technologies for Diabetic Foot management. It combines the current medical literature review with an overview of the technology and physics behind it. Thus, it is a single-source introduction to the topic. It can also be used as a reference source and practical guide for the use of technology. The particular focus is on low-cost technologies, including hyperspectral imaging, thermography, and endogenous bacterial fluorescence. Moving diagnostic modalities closer to the patient (e.g., primary care) allows the disease to be detected at an earlier stage, thus improving outcomes. However, while some optical technologies are available commercially, they have not received wide clinical adoption due to gaps in knowledge translation to mainstream medicine. This book aims to narrow this gap with practical illustrations. The book will be of interest to a broad range of healthcare professionals, clinical researchers, engineers, and decision-makers, who are dealing with complications of diabetes. Key Features: Reviews the current state of technologies. Provides a practical guide with practical considerations and illustrations. Supplies a 360-degree view of the combination of clinical information with a technology background and primers on physics and engineering.

Optimal Navigation in Active Matter (Springer Theses)

by Lorenzo Piro

Efficient navigation in terms of travel time and energy dissipation is of crucial importance for biological micro-swimmers. The design of optimally navigating artificial swimmers also has potentially valuable applications such as targeted drug delivery, which has become an increasingly realistic perspective due to the recent progress in the experimental realization of controllable microswimmers able to perform nontrivial tasks. Despite recent theoretical progress, the field still faces open challenges, notably in describing navigation problems that take into account the complexities of the world of microswimmers.This book presents a selection of works on the problem of optimal microswimmer navigation that represent a significant advance in this direction. The material in this book provides important insights into how efficient navigation may be achieved in the presence of curved space geometry, confining forces and flows, as well as thermal fluctuations. Finally, the energetic cost of navigation is addressed via a new formulation of the problem that accounts for the swimmer body geometry.

Optimal Transport Statistics for Economics and Related Topics (Studies in Systems, Decision and Control #483)

by Nguyen Ngoc Thach Vladik Kreinovich Doan Thanh Ha Nguyen Duc Trung

This volume emphasizes techniques of optimal transport statistics, but it also describes and uses other econometric techniques, ranging from more traditional statistical techniques to more innovative ones such as quantiles (in particular, multidimensional quantiles), maximum entropy approach, and machine learning. Applications range from general analysis of GDP growth, stock market, and consumer prices to analysis of specific sectors of economics (construction, credit and banking, energy, health, labor, textile, tourism, international trade) to specific issues affecting economy such as bankruptcy, effect of Covid-19 pandemic, effect of pollution, effect of gender, cryptocurrencies, and the existence of shadow economy. Papers presented in this volume also cover data processing techniques, with economic and financial application being the unifying theme. This volume shows what has been achieved, but even more important are remaining open problems. We hope that this volume will: inspire practitioners to learn how to apply state-of-the-art techniques, especially techniques of optimal transport statistics, to economic and financial problems, and inspire researchers to further improve the existing techniques and to come up with new techniques for studying economic and financial phenomena.

Optimierung: Ein interdisziplinäres Handbuch

by Markus Dederich Jörg Zirfas

Dieses interdisziplinäre Handbuch rekonstruiert Optimierung als ein Phänomen, das konstitutiv in aktuelle Entwicklungen der Gegenwart eingeschrieben ist. Denn es erscheint kaum mehr möglich, nicht optimieren zu wollen oder zu können. Das gilt für die Arbeit an sich selbst, die Verbesserung des Anderen und die Perfektionierung der Welt. Optimierung verspricht messbare Steigerungen von Effektivität und Effizienz sowie eine Erweiterung der Reichweite von Einfluss und Macht. Sie wirft aber auch Fragen der Instrumentalisierung, der Verdinglichung und Entfremdung sowie Fragen nach Grenzen und Unverbesserlichkeiten auf. Ohne eine Auseinandersetzung mit der Idee der Optimierung lässt sich eine moderne Humanwissenschaft heute nicht mehr konzipieren.

Optomechanics with Quantum Vacuum Fluctuations (Springer Theses)

by Zhujing Xu

This thesis presents the first realization of non-reciprocal energy transfer between two cantilevers by quantum vacuum fluctuations. According to quantum mechanics, vacuum is not empty but full of fluctuations due to zero-point energy. Such quantum vacuum fluctuations can lead to an attractive force between two neutral plates in vacuum – the so-called Casimir effect – which has attracted great attention as macroscopic evidence of quantum electromagnetic fluctuations, and can dominate the interaction between neutral surfaces at small separations. The first experimental demonstration of diode-like energy transport in vacuum reported in this thesis is a breakthrough in Casimir-based devices. It represents an efficient and robust way of regulating phonon transport along one preferable direction in vacuum. In addition, the three-body Casimir effects investigated in this thesis were used to realize a transistor-like three-terminal device with quantum vacuum fluctuations. These two breakthroughs pave the way for exploring and developing advanced Casimir-based devices with potential applications in quantum information science. This thesis also includes a study of the non-contact Casimir friction, which will enrich the understanding of quantum vacuum fluctuations.

Oral Bioavailability and Drug Delivery: From Basics to Advanced Concepts and Applications (Wiley Series in Drug Discovery and Development)

by Ming Hu Xiaoling Li

ORAL BIOAVAILABILITY AND DRUG DELIVERY Improve the performance and viability of newly-developed and approved drugs with this crucial guide Bioavailability is the parameter which measures the rate and extent to which a drug reaches a user’s circulatory system depending on the method of administration. For example, intravenous administration produces a bioavailability of 100%, since the drugs are injected directly into the circulatory system; in the case of oral administration, however, bioavailability can vary widely based on factors which, if not properly understood, can result in a failure in drug development, adverse effects, and other complications. The mechanics of oral bioavailability are therefore critical aspects of drug development. Oral Bioavailability and Drug Delivery provides a comprehensive coverage of this subject as well as its drug development applications. Beginning with basic terminology and fundamental concepts, it provides a thorough understanding of the challenges and barriers to oral bioavailability as well as the possibilities for improving this parameter. The resulting book is an indispensable tool for drug development research. Oral Bioavailability and Drug Delivery readers will also find: Discussion questions in many chapters to facilitate comprehension Detailed discussion of topics including dissolution, absorption, metabolism, and more Real-world examples of methods in actions throughout Oral Bioavailability and Drug Delivery is ideal for pharmaceutical and biotechnology scientists working in drug discovery and development; researchers in chemistry, biology, pharmacology, immunology, neuroscience, and other related fields; and graduate courses in drug development and delivery.

Ordering the Human: The Global Spread of Racial Science (Race, Inequality, and Health #15)

by Eram Alam, Dorothy Roberts, and Natalie Shibley

Modern science and ideas of race have long been entangled, sharing notions of order, classification, and hierarchy. Ordering the Human presents cutting-edge interdisciplinary scholarship that examines the racialization of science in various global contexts, illuminating how racial logics have been deployed to classify, marginalize, and oppress.These wide-ranging essays—written by experts in genetics, forensics, public health, history, sociology, and anthropology—investigate the influence of racial concepts in scientific knowledge production across regions and eras. Chapters excavate the mechanisms by which racialized science serves projects of power and domination, and they explore different forms of resistance. Topics range from skull collecting by eighteenth-century German and Dutch scientists to the use of biology to reinforce notions of purity in present-day South Korea and Brazil. The authors investigate the colonial legacies of the pathologization of weight for the Maori people, the scientific presumption of coronary artery disease risk among South Asians, and the role of racial categories in COVID-19 statistics and responses, among many other cases. Tracing the pernicious consequences of the racialization of science, Ordering the Human shines a light on how the naturalization of racial categories continues to shape health and inequality today.
