Introduction to Modeling Biological Cellular Control Systems

Natural selection is more than the survival of the fittest: it is a force engendering higher biological complexity. Presenting a new explanation for the tendency of life to become more complex through evolution, this book offers an introduction to the key debates in evolutionary theory, including the role of genes and sex in evolution, the adaptive reasons for senescence and death and the origin of neural information. The author argues that biological complexity increased through the process of 'modularity transfer': modular phenotypes (proteins, somatic cells, learned behaviours) evolved into new modular information carriers (regulatory proteins, neural cells, words), giving rise to new information systems and higher levels of biological organisation. Modular Evolution makes sense of the unique place of humans in evolution, both as the pinnacle of biological complexity and inventors of non-biological evolution.

This is an introduction to the mathematical basis of finite element analysis as applied to vibrating systems. Finite element analysis is a technique that is very important in modeling the response of structures to dynamic loads. Although this book assumes no previous knowledge of finite element methods, those who do have knowledge will still find the book to be useful. It can be utilised by aeronautical, civil, mechanical, and structural engineers as well as naval architects. This second edition includes information on the many developments that have taken place over the last twenty years. Existing chapters have been expanded where necessary, and three new chapters have been included that discuss the vibration of shells and multi-layered elements and provide an introduction to the hierarchical finite element method.

With mathematical and computational models furthering our understanding of lung mechanics, function and disease, this book provides an all-inclusive introduction to the topic from a quantitative standpoint. Focusing on inverse modeling, the reader is guided through the theory in a logical progression, from the simplest models up to state-of-the-art models that are both dynamic and nonlinear. Key tools used in biomedical engineering research, such as regression theory, linear and nonlinear systems theory, and the Fourier transform, are explained. Derivations of important physical principles, such as the Poiseuille equation and the wave speed equation, from first principles are also provided. Example applications to experimental data throughout illustrate physiological relevance, whilst problem sets at the end of each chapter provide practice and test reader comprehension. This book is ideal for biomedical engineering and biophysics graduate students and researchers wishing to understand

Insects counteract infection by a variety of reactions, partly humoral but principally cellular. This monograph considers their cellular reactions, especially the phagocytosis of micro-organisms and the encapsulation of larger parasites, from two main points of view: parasitological and cytologica. The first aspect involves description of the reactions and of their effects on parasites. This part of the subject is basic to the biological control of insect pests, because a better understanding of cellular defence reactions could lead to improved methods of using insect parasites to human advantage. The second aspect involves analysis of the stimuli that evoke cellular reactions. This part of the monograph attempts to relate the defensive activities of insect blood cells to general problems of cytology, such as the recognition of foreign bodies, the aggregation of cells and their adhesion to foreign surfaces and their extreme flattening on each other as they form capsules. Two final chap

First published in 1985, this book covers the physiological and environmental factors that regulate leaf growth. It opens with a consideration of the importance to the plant of leaf size, form and development, and then divides naturally into two sections: the first covers the intrinsic factors within the leaf that influence development, including solute and hormonal status, cellular components, and energy transducing systems; the second considers the role of some major environmental variables in the regulation of leaf growth, including temperature, light, water and nutrients, atmospheric influences and the interactive effects of climatic variables.

This concise undergraduate textbook brings together Earth and biological sciences to explore the co-evolution of the Earth and life over geological time. Written for a one-semester course, it explores the Earth system at and above the surface of the Earth by examining the interactions and feedback processes between the geosphere, atmosphere, hydrosphere and biosphere. It also explains how the Earth's surface environment involves a complex interplay between these systems. Through a wealth of features and student questioning, the book allows students to understand how physical controls make our planet hospitable for life, investigate the processes of global change that operate on a range of timescales, understand important cross-disciplinary connections and explore how the whole Earth system has evolved. Finally, it assesses how and why the climate of the Earth has varied over geological time, and considers whether life itself is passive or an active agent for change.

During development cells and tissues undergo changes in pattern and form that employ a wider range of physical mechanisms than at any other time in an organism's life. This book shows how physics can be used to analyze these biological phenomena. Written to be accessible to both biologists and physicists, major stages and components of the biological development process are introduced and then analyzed from the viewpoint of physics. The presentation of physical models requires no mathematics beyond basic calculus. Physical concepts introduced include diffusion, viscosity and elasticity, adhesion, dynamical systems, electrical potential, percolation, fractals, reaction-diffusion systems, and cellular automata. With full-color figures throughout, this comprehensive textbook teaches biophysics by application to developmental biology and is suitable for graduate and upper-undergraduate courses in physics and biology.

Linear systems can be regarded as a causal shift-invariant operator on a Hilbert space of signals, and by doing so this book presents an introduction to the common ground between operator theory and linear systems theory. The book therefore includes material on pure mathematical topics such as Hardy spaces, closed operators, the gap metric, semigroups, shift-invariant subspaces, the commutant lifting theorem and almost-periodic functions, which would be entirely suitable for a course in functional analysis; at the same time, the book includes applications to partial differential equations, to the stability and stabilization of linear systems, to power signal spaces (including some recent material not previously available in books), and to delay systems, treated from an input/output point of view. Suitable for students of analysis, this book also acts as an introduction to a mathematical approach to systems and control for graduate students in departments of applied mathematics or engin

The application of molecular biological techniques to the study of development has had a profound effect on our understanding of developmental processes. This 1985 book expounds some of the views on which hierarchies of genes control aspects of animal development. There is an emphasis on the best-studied systems, namely Drosophila and the nematode Caenorhabditis, though some features of mouse and sea-urchin development are also discussed. The book focuses on how information obtained from the study of mutants, combined with molecular details of the structure, regulation and functions of the genes involved, sheds light on the complex processes of animal development. The 1990 second edition, which is reprinted here, is an expanded and largely rewritten version of Dr de Pomerai's successful first edition. It features extensive additions to the chapter on insect development, a chapter discussing nematode development and another addressing differentiation in vertebrate systems.

Hankel operators are of wide application in mathematics (functional analysis, operator theory, approximation theory) and engineering (control theory, systems analysis) and this account of them is both elementary and rigorous. The book is based on graduate lectures given to an audience of mathematicians and control engineers, but to make it reasonably self-contained, the author has included several appendices on mathematical topics unlikely to be met by undergraduate engineers. The main prerequisites are basic complex analysis and some functional analysis, but the presentation is kept straightforward, avoiding unnecessary technicalities so that the fundamental results and their applications are evident. Some 45 exercises are included.
