Analysis and Control of Boolean Networks presents a systematic new approach to the investigation of Boolean control networks. The fundamental tool in this approach is a novel matrix product called the semi-tensor product (STP). Using the STP, a logical function can be expressed as a conventional discrete-time linear system. In the light of this linear expression, certain major issues concerning Boolean network topology - fixed points, cycles, transient times and basins of attractors - can be easily revealed by a set of formulae. This framework renders the state-space approach to dynamic control systems applicable to Boolean control networks. The bilinear-systemic representation of a Boolean control network makes it possible to investigate basic control problems including controllability, observability, stabilization, disturbance decoupling etc.

Our brain is the source of everything that makes us human: language, creativity, rationality, emotion, communication, culture, politics. The neuroscienceshave given us, in recent decades, fundamental new insights into how the brain works and what that means for how we see ourselves as individuals and ascommunities. Now - with the help of new advances in nanotechnology - brain science proposes to go further: to study its molecular foundations, to repair brainfunctions, to create mind-machine interfaces, and to enhance human mental capacities in radical ways. This book explores the convergence of these tworevolutionary scientific fields and the implications of this convergence for the future of human societies. In the process, the book offers a significant new approachto technology assessment, one which operates in real-time, alongside the innovation process, to inform the ways in which new fields of science and technologyemerge in, get shaped by, and help shape human societies."

The series Topics in Current Chemistry presents critical reviews of the present and future trends in modern chemical research. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. Review articles for the individual volumes are invited by the volume editors. Readership: research chemists at universities or in industry, graduate students.
The object of this book is to highlight how the nascent field of sustainability science is addressing a key challenges for scientists; that is, understanding the workings of complex systems especially when humans are involved. A consistent thread in the sustainability science movement is the wide acknowledgement that greater degrees of integration across what are now segmented dimensions of extant Science and Technology systems will be a key factor in matching the most appropriate science and technology solutions to specific sustainability problems in specific places.

This book highlights the importance of the choroid plexus, which forms the blood-cerebrospinal fluid barrier and is the site of the major production of the cerebrospinal fluid (CSF). The authors show that this barrier is crucial for maintaining important compositional differences between the blood plasma and the CSF. The choroid plexus epithelial cells also prevent the spread of infectious agents and other blood-borne entities to the brain tissue. Chapter topics range from the production of CSF by electrolyte regulation in the choroid plexus, to details on the selectively transporting nature of this barrier. Further, the authors elaborate on the important roles of CSF in sustaining brain health by providing hydration, solutes, and nutrients to the brain tissue. Readers will also learn how CSF circulates signaling molecules within the compartments of the brain and removes waste products from the brain tissue. Elucidating the regulation of these processes in the choroid plexus is not only important for the readers' understanding of normal brain development and function, but is also crucial for resolving a variety of cerebral challenges that lead to brain edema, as well as developing treatments for diseases. The book discusses disease models like hydrocephalus, sleep disorders, and age-related dementia. Its comprehensive coverage makes this volume a valuable resource for researchers in cell and neurophysiology, as well as graduate students of the neurosciences.
This book provides information about microbial mats, from early fossils to modern mats located in marine and terrestrial environments. Microbial mats layered biofilms containing different types of cells are most complex systems in which representatives of various groups of organisms are found together. Among them are cyanobacteria and eukaryotic phototrophs, aerobic heterotrophic and chemoautotrophic bacteria, protozoa, anoxygenic photosynthetic bacteria, and other types of microorganisms. These mats are perfect models for biogeochemical processes, such as the cycles of chemical elements, in which a variety of microorganisms cooperate and interact in complex ways. They are often found under extreme conditions and their study contributes to our understanding of extremophilic life. Moreover, microbial mats are models for Precambrian stromatolites; the study of modern microbial mats may provide information on the processes that may have occurred on Earth when prokaryotic life began to spread."
This book provides an assessment of some ethical implications of increasing life spans. Taking as a starting point the idea that to increase longevity is a form of medical enhancement, it examines the value of living longer; the means for extending life spans; the consequences of greater longevity for the fair distribution of resources and healthcare in particular.
This book analyzes the issues associated with climate change in the Himalayas. The purpose of choosing the Himalayas as a focus is because it is a particularly fragile mountain system, highly sensitive to climate change impacts, and it contains one of the largest human populations affected by climate change. The book provides extensive data and information regarding the climate history of the Himalayas, and the current effects of climate change on Himalayan weather systems, and on human and animal populations in the region. The book begins with an overview of global climate change with discussions of data trends and international initiatives, then segues into a history of climate changes and weather trends in the Himalayas. Weather systems of the Himalayas, both past and current, are analyzed and detailed through climate models, seasonal observations of weather fronts, and overviews of various climate scenarios. The book then discusses climate change impacts and signat ures specific to the Central Himalayan region, where the largest effects of impacts are observed. Readers will discover analysis presented on water resources, meteorological changes, biodiversity, agriculture and human health along with perspectives of management and policy. This book will appeal to researchers studying climate science, climatology, environmental scientists and policymakers.
'The Essential Tension' explores how agents that naturally compete come to act together as a group. The author argues that the controversial concept of multilevel selection is essential to biological evolution, a proposition set to stimulate new debate. The idea of one collective unit emerging from the cooperative interactions of its constituent (and mutually competitive) parts has its roots in the ancient world. More recently, it has illuminated studies of animal behavior, and played a controversial role in evolutionary biology. In Part I, the author explores the historical development of the idea of a collectivity in biological systems, from early speculations on the sociology of human crowd behavior, through the mid-twentieth century debates over the role of group selection in evolution, to the notion of the selfish gene. Part II investigates the balance between competition and cooperation in a range of contemporary biological problems, from flocking and swarming to experimental evolution and the evolution of multicellularity. Part III addresses experimental studies of cooperation and competition, as well as controversial ideas such as the evolution of evolvability and Stephen Jay Gould's suggestion that "spandrels" at one level of selection serve as possible sources of variability for the next higher level. Finally, building on the foundation established in the preceding chapters, the author arrives at a provocative new proposition: as a result of the essential tension between competition and cooperation, multiple levels may be essential in order for evolutionary processes to occur at all.
This manual offers a stand-alone reading companion, unique in simplifying the practical components of Bioinformatics in a unique and user-friendly manner. It covers the practical component of syllabi used at most leading universities and discusses the most extensively used tools and methodologies in Bioinformatics. Research in the biological sciences has made tremendous strides in recent years due in part to the increased automation in data generation. At the same time, storing, managing and interpreting huge volumes of data has become one of the most challenging tasks for scientists. These two aspects have ultimately necessitated the application of computers, giving rise to a highly interdisciplinary discipline-Bioinformatics. Despite the richness of bioinformatics resources and methods, the exposure of life sciences undergraduates and postgraduates to bioinformatics is extremely limited. Though the internet offers various tools for free, and provides guides for using them, it fails to help users interpret the processed data. Moreover, most sites fail to update their help pages to accommodate software upgrades. Though the market is flooded with books discussing the theoretical concepts in Bioinformatics, a manual of this kind is rarely found. The content developed to meet the needs of readers from diverse background and to incorporate the syllabi of undergraduate and postgraduate courses at various universities.
Neurons share more similarities with insulin-producing pancreatic islet cells than with any other cell type. The root of this similarity may lie in the islet's evolution from an ancestral insulin-producing neuron. The islet-neuron connection becomes less surprising as we learn more about insulin's involvement in functions far from its traditional role in mediating glucose uptake in muscle. The importance of insulin in the regulation of corporal aging has been established by the dramatic increases in longevity experienced by animals in which the adipose insulin receptor has been genetically eliminated, or in which the insulin-related daf genes have been mutated. New research suggests that, analogous to its influence on corporal aging, insulin also makes important contributions to brain aging and the expression of late-life neurodegenerative disease. Insulin plays a key role in cognition and other aspects of normal brain function. Insulin resistance induces chronic peripheral insulin elevations and is associated with reduced insulin activity both in periphery and brain. The insulin resistance syndrome underlies conditions such as Type 2 diabetes mellitus and hypertension, which are associated with age-related cognitive impairment and Alzheimer's disease. This book discusses the mechanisms through which insulin dysregulation contributes to the development of cognitive impairment and late-life neurodegenerative disease. Given the recent pandemic of conditions associated with insulin resistance, it is imperative that we achieve a comprehensive knowledge of the mechanisms through which insulin resistance affects brain function in order to develop therapeutic strategies to address these effects.

Evolutionary theory addresses the phenomenon of the origin and diversity of plant and animal species that we observe. In recent times, however, it has become a predominant ideology which has gained currency far beyond its original confines. Attempts to understand the origin and historical development of human culture, civilization and language, of the powers of human cognition, and even the origin of the moral and ethical values guiding and constraining everyday life in human societies are now cast in an evolutionary context. In "Evolutionary Theory and the Creation Controversy" the author examines evolutionary theory from a historical perspective, explaining underlying metaphysical backgrounds and fundamental philosophical questions such as the paradoxical problem of change, existence and creation. He introduces the scientists involved, their research results and theories, and discusses the evolution of evolutionary theory against the background of Creationism and Intelligent Design.

KEY TOPICS:
The hearing organs of non-mammals, which show quite large and systematic differences to each other and to those of mammals, provide an invaluable basis for comparisons of structure and function. By taking advantage of the vast diversity of possible study organisms provided by the "library" that is biological diversity, it is possible to learn how complex functions are realized in the inner ear through the evolution of specific structural, cellular and molecular configurations. Insights from Comparative Hearing Research brings together some of the most exciting comparative research on hearing and shows how this work has profoundly impacted our understanding of hearing in all vertebrates.
This book traces the history of life-concepts, with a focus on the vegetable souls of Aristotle, investigating how they were interpreted and eventually replaced by evolutionary biology. Philosophers have long struggled with the relationship between physics, physiology, and psychology, asking questions of organization, purpose, and agency. For two millennia, the vegetable soul, nutrition, and reproduction were commonly used to understand basic life and connect it to "higher" animal and vegetable life. Cartesian dualism and mechanism destroyed this bridge and left biology without an organizing principle until Darwin. Modern biology parallels Aristotelian vegetable life-concepts, but remains incompatible with the animal, rational, subjective, and spiritual life-concepts that developed through the centuries. Recent discoveries call for a second look at Aristotle's ideas - though not their medieval descendants. Life remains an active, chemical process whose cause, identity, and purpose is self-perpetuation.
This book gives basic facts about litter decomposition studies, which are of guidance for scientists who start studies. Since the publication of the third edition, there has been quite a development not only in the field of litter decomposition but also in supporting branches of science, which are important for fruitful work on and understanding of decomposition of plant litter and sequestration of carbon. A consequence is that 'old established truths' are becoming outdated. New knowledge in the fields of phytochemistry and microbial ecology has given a new baseline for discussing the concepts 'litter decomposition' and 'carbon sequestration'. We can also see a rich literature on litter decomposition studies using roots and wood as substrates. These have given new insights in factors that regulate the decomposition rate and as regards roots their contribution to sequestered carbon in humus. Additional facts on the role of temperature vs the litters' chemical composition may in part change our view on effects of climate change. Further information on applications of the new analytical technique (13C-NMR) for determining organic-chemical compounds has allowed us to develop these parts. Focus is laid on needle litter of Scots pine as a model substrate as this species has been considerably more studied than other litter species. Also the boreal/northern temperate coniferous forest has in part been given this role. Still, new information may allow us to develop information about litter from further tree species.
