Book Description
There is a growing interest in programming languages and systems, and computational models based on intensional logics — such as temporal logic, interval logic and modal logic — and possible world semantics. In fact, a whole new programming model called intensional programming has emerged with applications in a wide range of areas including parallel programming, dataflow computation, temporal reasoning, scientific computation, software version control, real-time programming, temporal query languages, executable temporal logics, spreadsheets, attribute grammars, and hardware synthesis, to name a few. Intensional Programming is especially suited to application domains where the notion of dynamic change is central.This collection will feature papers by leading researchers in the field of intensional programming dealing with theoretical foundations, design, implementation and prototype development issues, comparative studies, and applications, as well as those describing new challenges arising out of applications. It contains revised and extended versions of the papers presented at the Eighth International Symposium on Languages for Intensional Programming held on May 3-5, 1995 at Macquarie University in Sydney, Australia.

Book Description
With a spirit of exploration rarely seen in modern times, Ben Long and his wife, Karen Nichols, quit their jobs, sold their house, and set out to follow in the footsteps of Meriwether Lewis and William Clark. Their quest: To look at the plants and animals encountered during the Corps of Discovery's great endeavor and report on how nature is doing after two centuries of "civilization." Long's voice is appealing, and readers will have no trouble imagining themselves traveling along with the couple in their fully loaded Subaru. Long and Nichols drove from Montana to the Pacific, checking on Lewis and Clark's natural "discoveries" along the way: prairie dogs, cutthroat trout, sharptail grouse, coyotes, beavers, bison, grizzlies, whitebark pine, even a dinosaur fossil. Everywhere, they encounter another persistent force of nature -- human nature. This highly readable travelogue is informed by humor, history, the sacred journals of Lewis and Clark, and the vivid experience of discovery.

Book Description
Bacteria in various habitats are subject to continuously changing environmental conditions, such as nutrient deprivation, heat and cold stress, UV radiation, oxidative stress, dessication, acid stress, nitrosative stress, cell envelope stress, heavy metal exposure, osmotic stress, and others. In order to survive, they have to respond to these conditions by adapting their physiology through sometimes drastic changes in gene expression. In addition they may adapt by changing their morphology, forming biofilms, fruiting bodies or spores, filaments, Viable But Not Culturable (VBNC) cells or moving away from stress compounds via chemotaxis. Changes in gene expression constitute the main component of the bacterial response to stress and environmental changes, and involve a myriad of different mechanisms, including (alternative) sigma factors, bi- or tri-component regulatory systems, small non-coding RNA’s, chaperones, CHRIS-Cas systems, DNA repair, toxin-antitoxin systems, the stringent response, efflux pumps, alarmones, and modulation of the cell envelope or membranes, to name a few. Many regulatory elements are conserved in different bacteria; however there are endless variations on the theme and novel elements of gene regulation in bacteria inhabiting particular environments are constantly being discovered. Especially in (pathogenic) bacteria colonizing the human body a plethora of bacterial responses to innate stresses such as pH, reactive nitrogen and oxygen species and antibiotic stress are being described. An attempt is made to not only cover model systems but give a broad overview of the stress-responsive regulatory systems in a variety of bacteria, including medically important bacteria, where elucidation of certain aspects of these systems could lead to treatment strategies of the pathogens. Many of the regulatory systems being uncovered are specific, but there is also considerable “cross-talk” between different circuits. Stress and Environmental Regulation of Gene Expression and Adaptation in Bacteria is a comprehensive two-volume work bringing together both review and original research articles on key topics in stress and environmental control of gene expression in bacteria. Volume One contains key overview chapters, as well as content on one/two/three component regulatory systems and stress responses, sigma factors and stress responses, small non-coding RNAs and stress responses, toxin-antitoxin systems and stress responses, stringent response to stress, responses to UV irradiation, SOS and double stranded systems repair systems and stress, adaptation to both oxidative and osmotic stress, and desiccation tolerance and drought stress. Volume Two covers heat shock responses, chaperonins and stress, cold shock responses, adaptation to acid stress, nitrosative stress, and envelope stress, as well as iron homeostasis, metal resistance, quorum sensing, chemotaxis and biofilm formation, and viable but not culturable (VBNC) cells. Covering the full breadth of current stress and environmental control of gene expression studies and expanding it towards future advances in the field, these two volumes are a one-stop reference for (non) medical molecular geneticists interested in gene regulation under stress.

Book Description
In his master thesis, Vladimir Herdt presents a novel approach, called complete symbolic simulation, for a more efficient verification of much larger (non-terminating) SystemC programs. The approach combines symbolic simulation with stateful model checking and allows to verify safety properties in (cyclic) finite state spaces, by exhaustive exploration of all possible inputs and process schedulings. The state explosion problem is alleviated by integrating two complementary reduction techniques. Compared to existing approaches, the complete symbolic simulation works more efficiently, and therefore can provide correctness proofs for larger systems, which is one of the most challenging tasks, due to the ever increasing complexity.

Book Description
Biophysics is a new way of looking at living matter. It uses quantitative experimental, theoretical, and computational methods, thereby opening a new window for studying and understanding life processes. This textbook provides a brief introduction to the basics of the field, followed by in-depth discussions of more advanced biophysics subjects, going all the way to state-of-the-art experiments and their theoretical interpretations. The second edition presents some of the newest developments in the field (e.g., biomolecular condensates, loop extrusion), a new chapter on computational methods, and many computer exercises specially designed for this textbook.

Book Description
This book presents recently developed intelligent techniques with applications and theory in the area of engineering management. The involved applications of intelligent techniques such as neural networks, fuzzy sets, Tabu search, genetic algorithms, etc. will be useful for engineering managers, postgraduate students, researchers, and lecturers. The book has been written considering the contents of a classical engineering management book but intelligent techniques are used for handling the engineering management problem areas. This comprehensive characteristics of the book makes it an excellent reference for the solution of complex problems of engineering management. The authors of the chapters are well-known researchers with their previous works in the area of engineering management.

Book Description
This book constitutes the proceedings of the 23rd International Conference on Theory and Applications of Satisfiability Testing, SAT 2020, which was planned to take place in Alghero, Italy, during July 5-9, 2020. Due to the coronavirus COVID-19 pandemic, the conference was held virtually. The 25 full, 9 short, and 2 tool papers presented in this volume were carefully reviewed and selected from 69 submissions. They deal with SAT interpreted in a broad sense, including theoretical advances (such as exact algorithms, proof complexity, and other complexity issues), practical search algorithms, knowledge compilation, implementation-level details of SAT solvers and SAT-based systems, problem encodings and reformulations, applications (including both novel application domains and improvements to existing approaches), as well as case studies and reports on findings based on rigorous experimentation.
