Cell Biology of Physarum and Didymium, Volume I: Organisms, Nucleus, and Cell Cycle presents important experimental research on Physarum and Didymium for developmental and cellular studies. This book is organized into four parts, encompassing 12 chapters that summarize the taxonomy, biological activities, genetics, and cell cycle of these organisms. The opening part covers two chapters on morphology, taxonomy, phylogeny, biosystematics, and evolutionary implications of Physarum and Didymium species. This is followed by discussions on the biological aspects of these species. These include periodic events of the mitotic cycle in Physarum polycephalum. The general characteristics of chemoreception at the membrane level using plasmodium as a model organism, as well as the structure and motility of plasmodium, are also included. The third part of the book focuses on genetic analysis of plasmodium development and the discovery of techniques for the genetic manipulation of P. polycephalum. Progress in the genetic analysis of other processes is summarized. The concluding part examines the morphological evolution of the nucleus during the mitotic cycle together with the results from ultracytochemical and radioautographic studies. It also includes a discussion on DNA organization and replication in P. polycephalum. Finally, the synthesis and degradation of RNA in Physarum and the relationship of these biochemical processes to mitotic cycle and differentiation are tackled in the concluding chapter. The book will serve as a frequent, single reference source to brief cell biologists on the primary research on Physarum and Didymium. It will be a good source for graduate students in cell biology, and perhaps in other graduate courses.

This book is devoted to Slime mould Physarum polycephalum, which is a large single cell capable for distributed sensing, concurrent information processing, parallel computation and decentralized actuation. The ease of culturing and experimenting with Physarum makes this slime mould an ideal substrate for real-world implementations of unconventional sensing and computing devices The book is a treatise of theoretical and experimental laboratory studies on sensing and computing properties of slime mould, and on the development of mathematical and logical theories of Physarum behavior. It is shown how to make logical gates and circuits, electronic devices (memristors, diodes, transistors, wires, chemical and tactile sensors) with the slime mould. The book demonstrates how to modify properties of Physarum computing circuits with functional nano-particles and polymers, to interface the slime mould with field-programmable arrays, and to use Physarum as a controller of microbial fuel cells. A unique multi-agent model of slime is shown to serve well as a software slime mould capable for solving problems of computational geometry and graph optimization. The multiagent model is complemented by cellular automata models with parallel accelerations. Presented mathematical models inspired by Physarum include non-quantum implementation of Shor's factorization, structural learning, computation of shortest path tree on dynamic graphs, supply chain network design, p-adic computing and syllogistic reasoning. The book is a unique composition of vibrant and lavishly illustrated essays which will inspire scientists, engineers and artists to exploit natural phenomena in designs of future and emergent computing and sensing devices. It is a 'bible' of experimental computing with spatially extended living substrates, it spanstopics from biology of slime mould, to bio-sensing, to unconventional computing devices and robotics, non-classical logics and music and arts.

The unconventional computing is a niche for interdisciplinary science, cross-bred of computer science, physics, mathematics, chemistry, electronic engineering, biology, material science and nanotechnology. The aims of this book are to uncover and exploit principles and mechanisms of information processing in and functional properties of physical, chemical and living systems to develop efficient algorithms, design optimal architectures and manufacture working prototypes of future and emergent computing devices. This second volume presents experimental laboratory prototypes and applied computing implementations. Emergent molecular computing is presented by enzymatic logical gates and circuits, and DNA nano-devices. Reaction-diffusion chemical computing is exemplified by logical circuits in Belousov-Zhabotinsky medium and geometrical computation in precipitating chemical reactions. Logical circuits realised with solitons and impulses in polymer chains show advances in collision-based computing. Photo-chemical and memristive devices give us a glimpse on hot topics of a novel hardware. Practical computing is represented by algorithms of collective and immune-computing and nature-inspired optimisation. Living computing devices are implemented in real and simulated cells, regenerating organisms, plant roots and slime mould. The book is the encyclopedia, the first ever complete authoritative account, of the theoretical and experimental findings in the unconventional computing written by the world leaders in the field. All chapters are self-contains, no specialist background is required to appreciate ideas, findings, constructs and designs presented. This treatise in unconventional computing appeals to readers from all walks of life, from high-school pupils to university professors, from mathematicians, computers scientists and engineers to chemists and biologists.

Zahlreiche Teilgebiete der modernen Biologie weisen seit geraumer Zeit eine gleichartige Entwicklungstendenz auf: Die Phase des Beschreibens von Einzelbeobachtungen und ihre Zusammenfassung mit dem Ziele des Erkennens von GesetzmiiBigkeiten beim Ablauf bestimmter Grundvorgiinge des Belebten ist weitgehend abgeschlos sen. In einer zweiten Phase hat vor allem die Forschung der ersten Hiilfte des 20. lahrhunderts an zahlreichen Beispielen die dazugehori gen makroskopisch oder auch mikroskopisch erkennbaren, mechani schen Gesetzen unterliegenden Mechanismen beschrieben und analy siert. Weite Gebiete der modernen biologischen Forschung lassen durch die Art ihrer experimentellen Fragestellung einen weiteren Entwicklungsschritt erkennen: Die Wurzeln der Ursachen solcher Mechanismen, weIche die Grundvorgiinge des Belebten hervorbrin gen, werden in den molekularen Bereich verlegt. Der molekulare Aufbau und die sich aus ihm ergebenden chemischen Reaktionen bestimmter Molekiilarten sind nach dieser Vorstellung die Grundlage fiir den Ablauf der vielen, sehr spezifischen Teilvorgiinge, weIche in ihrer Gesamtheit als Leben bezeichnet werden. Biologische und chemische Forschung reichen sich bei der Schaffung einer molekularen Biologie die Hand. Ohne Zweifel ist im Vergleich zu den anderen Teilgebieten der Mole kularbiologie die molekulare Genetik mit ihren Aussagen am weitesten fortgeschritten, bietet das geschlossenste Bild. Sie weist nach, daB es letzten Endes die Molekiile eines einzigen Bautyps - die Nuclein siiuren -sind, deren besondere Merkmale und Reaktionsbefiihigungen die wesentlichen Teilvorgiinge der Vererbung bedingen. Aus diesem Gesichtswinkel heraus ist eine Darstellung der molekularen Genetik im weitesten Sinne eine Monographie iiber die biologische Bedeutung der Nucleinsiiuren.
