Micrometeorites and the Mysteries of Our Origins

This book relates an attempt to decrypt the still-obscure first billion years of history of the young Earth, during a cataclysmic period during which our planet was heavily bombarded by bodies ranging in size from that of Mars to 0.1 mm sized tiny micrometeorites. It was thus found that micrometeorites played an essential role in the formation of the post-lunar atmosphere. They also provided a surprisingly large diversity of reactions in the organic prebiotic chemistry required for the birth of life on our blue planet. The author presents a wide-ranging review of the type of knowledge required to decrypt this history, which provides extensive background information from astronomy, planetary dynamics, planetology, astrobiology and earth sciences. This book will appeal to both the scientist and the general reader. It will be a source of material for lectures, and possibly new investigations, in these fields.

Micromechanics of Contact and Interphase Layers

Micromechanics provides a link between the structure and the properties at different scales of observation. This book deals with micromechanical analysis of interfaces and interface layers and presents several modelling tools, ranging from the rigorous method of asymptotic expansions to practical finite element simulations, suitable for this class of problems. Two application areas are discussed. Boundary layers associated with contact of rough bodies are modelled by applying a scale transition approach in which a macroscopic interface of zero thickness is seen at the micro-scale as a layer with some finite thickness. Secondly, evolution of laminated microstructures accompanying stress-induced martensitic transformations in shape memory alloys (SMA) is analyzed as an illustration of the case when the local interfacial phenomena – here the propagation of phase transformation fronts – govern the macroscopic behaviour of a heterogeneous material.

Micromammals and Macroparasites : From Evolutionary Ecology to Management

Small mammals are among the most ubiquitous and important components of terrestrial ecosystems. They have coevolved, and now coexist, with a diverse array of parasites, such that not only are all aspects of their biology influenced by parasitism but they also play key roles in the transmission and maintenance of parasitic diseases. This book provides a comprehensive survey of the diversity and biology of metazoan parasites affecting small mammals, of their impact on host individuals and populations, and of the management implications of these parasites for conservation biology and human welfare. Designed for a broad, multidisciplinary audience, it will be an essential resource for researchers, students, and practitioners alike in the fields of parasitology, evolutionary ecology, wildlife management, and conservation biology.

Methods of Celestial Mechanics ; Vol. II : Application to Planetary System, Geodynamics and Satellite Geodesy

G. Beutler's Methods of Celestial Mechanics is a coherent textbook for students as well as an excellent reference for practitioners. Volume II is devoted to the applications and to the presentation of the program system CelestialMechanics. Three major areas of applications are covered: (1) Orbital and rotational motion of extended celestial bodies. The properties of the Earth-Moon system are developed from the simplest case (rigid bodies) to more general cases, including the rotation of an elastic Earth, the rotation of an Earth partly covered by oceans and surrounded by an atmosphere, and the rotation of an Earth composed of a liquid core and a rigid shell (Poincaré model). (2) Artificial Earth Satellites. The oblateness perturbation acting on a satellite and the exploitation of its properties in practice is discussed using simulation methods (CelestialMechanics) and (simplified) first order perturbation methods. The perturbations due to the higher-order terms of the Earth's gravitational potential and resonant perturbations are considered thereafter. Special attention is paid to satellites of the Global Navigation Satellite Systems and to geostationary satellites. The characteristics of and models for the two most important non-gravitational forces, atmospheric drag and radiation pressure, are presented as well as the most relevant forces acting on high- and low-orbiting satellites. (3) Evolution of the Planetary System. The outer planetary system consisting of the planets Jupiter to Pluto is studied over long time intervals using simulation methods and spectral analysis (CelestialMechanics). The properties of the inner systems, in particular of the Earth's orbit, are made visible by integrating the entire system over long time intervals relevant for climate change. The distribution of minor planets and their orbital properties, regular orbits, and chaotic orbits are easily generated and analyzed using CelestialMechanics. The volume concludes with the discussion of important mathematical tools of the program system and of the principles of spectral analysis.

Metal Catalyzed Cascade Reactions

Transition metal-catalyzed cascade reactions are an elegant approach to complex molecular scaffolds. Besides their esthetics and increase in structural complexity, they have also become mechanistic challenges for the combination of organometallic elementary steps. As a consequence, cascade reactions have revolutionized synthetic strategies and conceptual thinking. The authors highlight cyclization via carbopalladation and acylpalladation and Heck-pericyclic sequences. They discuss p-allyl palladium-based cascade reactions, Michael-type additions as an entry to transition-metal-promoted cyclizative transformations, and sequential or consecutive palladium-catalyzed processes, and show Pauson-Khand cascades, metal-catalyzed cyclizations of acyclic precursors, as well as cascade and sequential ruthenium-catalyzed transformations. Therefore, the reader finds overview of an exciting and highly dynamic field of a new and innovative methodological concept

Metaheuristic Optimization via Memory and Evolution : Tabu Search and Scatter Search

Tabu Search (TS) and, more recently, Scatter Search (SS) have proved highly effective in solving a wide range of optimization problems, and have had a variety of applications in industry, science, and government. The goal of METAHEURISTIC OPTIMIZATION VIA MEMORY AND EVOLUTION: Tabu Search and Scatter Search is to report original research on algorithms and applications of tabu search, scatter search or both, as well as variations and extensions having "adaptive memory programming" as a primary focus. Individual chapters identify useful new implementations or new ways to integrate and apply the principles of TS and SS, or that prove new theoretical results, or describe the successful application of these methods to real world problems.The chapters of this book provide a series of landmarks along the way as we investigate and seek to better understand the elements of tabu search and scatter search that account for their successes in an astonishingly varied range of applications.

Messenger RNA therapeutics

Focuses on the fundamentals and applications of messenger RNA (mRNA)-based therapeutics and discusses the strengths and key challenges of this emerging class of drugs. In the past 30 years, extensive research and technological development in many areas have contributed to the emergence of in vitro transcribed mRNA as a therapeutic that has now reached clinical testing. Formulations that protect the mRNA from nucleases and accelerate its cellular uptake, combined with improvements to the mRNA molecules themselves, have been critical advancements for mRNAs to become viable therapeutics. Though once regarded as a serious impediment, the transient nature of mRNA technology is now considered a major advantage in making mRNA therapies safe and, ultimately, a potential game changer in the field of medicine. This new book in the RNA Technologies series provides a state-of-the-art overview on the emerging field of mRNA therapeutics covering essential strategies for formulation, delivery, and application. It also reviews the promising role in cancer immunotherapy, respiratory diseases, and chronic HBV infection and discusses RNA vaccines in light of the current COVID-19 pandemic. mRNA-based approaches have great potential to revolutionize molecular biology, cell biology, biomedical research, and medicine.

MEMS/NEMS : (1) Handbook Techniques and Applications Design Methods, (2) Fabrication Techniques, (3) Manufacturing Methods, (4) Sensors and Actuators, (5) Medical Applications and MOEMS

Micro-Electro Mechanical Systems (MEMS) is the integration of mechanical elements, sensors, actuators, and electronics on a common silicon substrate. While the electronics are fabricated using integrated circuit (IC) process sequences (e.g., CMOS, Bipolar, or BICMOS processes),the micromechanical components are fabricated using compatible micromachining processes that selectively etch away parts of the silicon wafer or add new structural layers to form the mechanical and electromechanical devices. MEMS promises to revolutionize nearly every product category by bringing together silicon-based microelectronics with micromachining technology, thereby, making possible the realization of complete systems-on-a-chip.

Medical Emergency Teams : Implementation and Outcome Measurement

Why Critical Care Evolved METs? In early 2004, when Dr. Michael DeVita informed me that he was cons- ering a textbook on the new concept of Medical Emergency Teams (METs), I was surprised. At Presbyterian-University Hospital in Pittsburgh we int- duced this idea some 15 years ago, but did not think it was revolutionary enough to publish. This, even though, our fellows in critical care medicine training were all involved and informed about the importance of “C- dition C (Crisis),” as it was called to distinguish it from “Condition A (Arrest). ”We thought it absurd to intervene only after cardiac arrest had occurred,because most cases showed prior deterioration and cardiac arrest could be prevented with rapid team work to correct precluding problems. The above thoughts were logical in Pittsburgh, where the legendary Dr. Peter Safar had been working since the late 1950s on improving current resuscitation techniques, ?rst ventilation victims of apneic from drowning, treatment of smoke inhalation, and so on. This was followed by external cardiac compression upon demonstration of its ef?ciency in cases of unexpected sudden cardiac arrest. Dr. Safar devoted his entire professional life to improvement of cardiopulmonary resuscitation. He and many others emphasized the importance of getting the CPR team to o- of-hospital victims of cardiac arrest as quickly as possible.

Medical data processing and analysis

Medical data can be defined as obtaining information from patients (such as signals, images, sounds, chemical components and their concentration, body temperature, respiratory rate, blood pressure, and different treatment measurements) to quantify the patient’s status and disease stage. Computer-aided diagnostic (CAD) systems use classical image processing, computer vision, machine learning, and deep learning methods for image analysis. Using image classification or segmentation algorithms, they find a region of interest (ROI) pointing to a specific location within the given image or an outcome of interest in the form of a label pointing to a diagnosis or prognosis. Computer science, with the evolution of artificial intelligence and machine learning techniques, facilitates the modeling and interpretation of results—from carrying out measurements to experiments and observations.

Media Theory : Interdisciplinary Applied Mathematics

The focus of this book is a mathematical structure modeling a physical or biological system that can be in any of a number of `states.' Each state is characterized by a set of binary features, and differs from some other neighbor state or states by just one of those feature. A simple example of a `state’ is a partial solution of a jigsaw puzzle, which can be transformed into another partial solution or into the final solution just by adding or removing a single adjoining piece. The evolution of such a system over time is considered. Such a structure is analyzed from algebraic and probabilistic (stochastic) standpoints.
