This book focuses mainly on the recent developments of all types of theoretical, mathematical, and computational conceptions, as well as modelling and simulation of specific research themes covering all scientific and technical disciplines from chemistry, physics, and engineering to biology and medicine. The book contains timely reviews and research covering fundamental and applied research aspects in all disciplines of natural sciences, including their historical representations and philosophical perspectives. The book discusses the fact that the largest and smallest values of the fukui function and local softness do not necessarily correspond to the softness and hardness regions of the molecules such as porphyrins. The authors have adopted two popular calculation procedures for this venture. One is the very old Hückel molecular orbital calculation, and the other is one of best semi-empirical AM-1 procedures for such systems. Our finding is that neither the fukui functions nor the local softnesses can predict the preferred donor sites of porphyrins toward metal ions.

"God's Physics": A New Science Transforming the World & Our Life Science is currently undergoing a profound "Paradigmatic-Shift" from the Old "Material-Causal" Paradigm of 20th Century's Relativity Theory and Quantum Mechanics to the New "God's Physics" Paradigm: Succinctly stated, 'God's Physics' replaces our old way of looking at the world as created by a "random Big-Bang" nuclear explosion towards an exciting new realization that our entire physical universe, our bodies and minds, and our total physical and human existence are all being continuously created by a singular higher "Universal Consciousness Reality" – 'God'! Yes, according to this New 'God's Physics' Paradigm there exists a singular higher 'Universal Consciousness Reality' which "produces", "remembers", "sustains" and "evolves" every small "pixel" in our entire physical universe – including our own body and mind, helps and encourages us to lead a moral, purposeful and meaningful life! Indeed, according to this New 'God's Physics' understanding of the world, everything in our universe, e.g., from the tiniest cells in our bodies, every atom in the universe, every rock, plant, animal or human being – are all being produced and re-produced a "billion-billion-billion" times (per second!) by this singular higher 'Universal Consciousness Reality' (UCR), i.e., 'God'! Indeed, this profound new scientific discovery comes along with the realization that this singular higher 'Universal Consciousness Reality' cares about our own 'moral-choices', evolves every small 'pixel' in the universe as well as us as (intelligent conscious) human beings towards leading a Moral, Spiritual Existence within an "awakened" New Morally and Spiritually Perfected World! Therefore, the discovery of this new (exciting) "God's Physics" not only resolves the biggest unresolved "Scientific Enigma" that Einstein was working on for half of his illustrious scientific career – but also completely transf

Although its importance is not always recognized, theory is an integral part of all biological research. Biologists' theoretical and conceptual frameworks inform every step of their research, affecting what experiments they do, what techniques and technologies they develop and use, and how they interpret their data. By examining how theory can help biologists answer questions like "What are the engineering principles of life?" or "How do cells really work?" the report shows how theory synthesizes biological knowledge from the molecular level to the level of whole ecosystems. The book concludes that theory is already an inextricable thread running throughout the practice of biology; but that explicitly giving theory equal status with other components of biological research could help catalyze transformative research that will lead to creative, dynamic, and innovative advances in our understanding of life.

The scientific developments at the end of the past millennium were dominated by the huge increase and diversity of disciplines with the common label "computer science". The theoretical foundations of such disciplines have become known as theoretical computer science. This book highlights some key issues of theoretical computer science as they seem to us now, at the beginning of the new millennium. The text is based on columns and tutorials published in the Bulletin of the European Association for Theoretical Computer Science in the period 1995 -- 2000. The columnists themselves selected the material they wanted for the book, and the editors had a chance to update their work. Indeed, much of the material presented here appears in a form quite different from the original. Since the presentation of most of the articles is reader-friendly and does not presuppose much knowledge of the area, the book constitutes suitable supplementary reading material for various courses in computer science.

Vector Partitions, Visible Points and Ramanujan Functions offers a novel theory of Vector Partitions, though very much grounded in the long-established work of others, that could be developed as an extension to the existing theory of Integer Partitions. The book is suitable for graduate students in physics, applied mathematics, number theory and computational mathematics. It takes the reader up to research level, presenting new results alongside known classical results from integer partitions and areas of vector and multipartite partition theory. It also sets forth new directions for research for the more advanced reader. Above all, the intention of the book is to bring new inspiration to others who study mathematics and related areas. It is hoped that some new ideas will be launched to add value and insight into many of the classical and new theories surrounding partitions. The book is an appreciation of the many gifted authors of research into partitions over the past century and before, in the hope that more may come of this for future generations. Features Provides a step-by-step guide through the known literature on Integer and Vector Partitions, and a focus on the not so well-known Visible Point Vector identities Serves as a reference for graduate students and researchers in physics, applied mathematics, number theory and computational mathematics Offers a variety of practical examples as well as sets of exercises suitable for students and researchers Geoffrey B.
