Book Description
The first edition of this book was greeted with broad interest from readers en gaged in various disciplines of biophysics. I received many stimulating and en couraging responses, however, some of the book's reviewers wanted to stress the fact that an extensive literature of network theory was not included or reported in the book. But the main aspect of the book is intended to be substantive rather than methodical: networks simply serve as a remedy for doing some first steps in analysing and modelling complex biological systems. For an advanced stage in the investigation of a particular system it may be appropriate to replace the pheno menological network method by more detailed techniques like statistical equations or computer simulations. According to this intention, the second edition of the book has been enlarged by further biological examples for network analysis, not by more network theory. There is a completely new section on a network model for photoreception. For this section I am obliged to J. Tiedge who did most of the detailed calculation and to my colleague Professor Stieve with whom we have had a very fruitful cooperation. Also I would like to mention that this work has been sponsored by the "Deutsche Forschungsgemei nschaft" i n the "Sonderforschungsberei ch 160". Recent results for excitable systems represented by feedback networks have also been included in the second edition, especially for limit cycle networks.

Book Description
This volume represents a collection of studies in cultural history and theory of science from the early modern era to the present. The essays are linked by the conviction that one of the most significant developments in recent scientific historiography consists in its insistence that the relations between science, culture and history be understood and examined reciprocally. Not only does scientific practice take place under conditions shaped by social and cultural forces; it also generates and necessitates its own specific patterns of cultural, social and political activity. Sciences which have evolved into significant social systems produce their own cultures and politics. Through discussion of the common origin of scientific knowledge and the cultures and politics of research, this volume hopes to make a contribution toward a better understanding of the roles of scientific research from its inception in the 17th century up to the dramatic upheavals in the 20th century. With articles by Lorraine Daston, Sven Dierig, Moritz Epple, Evelyn Fox Keller, Mary Jo Nye , Dominique Pestre, Hans-Jörg Rheinberger, Simon Schaffer, Friedrich Steinle, Catherine Wilson, Norton M. Wise and Claus Zittel. Der Band in englischer Sprache versammelt Studien zur Kulturgeschichte und Theorie der Wissenschaften von der Frühen Neuzeit bis zur Gegenwart. Vereinigt sind die Beiträge durch die Überzeugung, dass eine der folgenreichsten Interventionen der jüngeren Wissenschaftsgeschichte darin liegt, dass die Beziehungen zwischen Wissenschaft, Kultur und Gesellschaft auf reziproke Weise verstanden und untersucht werden müssen. Wissenschaftliche Praxis findet nicht nur stets unter sozial und kulturell geprägten Bedingungen statt, sie erzeugt und erfordert auch eigene, spezifische Muster kulturellen, sozialen und politischen Handelns. Die Wissenschaften, die zu sozialen Systemen bedeutender Größe angewachsen sind, schaffen ihre eigenen Kulturen und Politiken. Durch die Diskussion der gemeinsamen Entstehung wissenschaftlichen Wissens und der Kulturen und Politiken der Forschung leistet der Band einen Beitrag zu einem besseren Verständnis der Rollen wissenschaftlicher Forschung von ihrer Formierung im 17. Jahrhundert bis zu den dramatischen Umbrüchen des 20. Jahrhunderts. Mit Beiträgen von Lorraine Daston, Sven Dierig, Moritz Epple, Evelyn Fox Keller, Mary Jo Nye , Dominique Pestre, Hans-Jörg Rheinberger, Simon Schaffer, Friedrich Steinle, Catherine Wilson, Norton M. Wise und Claus Zittel.

Book Description
Mass Action in the Nervous System: Examination of the Neurophysiological Basis of Adaptive Behavior through the EEG focuses on the neural mechanisms and the behavioral significance of the electroencephalogram, with emphasis on observations made on the mammalian olfactory system. Organized into seven chapters, this book begins with a brief nonmathematical review of the concept of the neuron and the interrelations among neurons that lead to the formation of interactive masses. Some chapters follow on the linear properties of neurons and their parts; the ionic hypothesis; the nonlinear input-output relations of neurons in masses expressed in terms of amplitude-dependent coefficients in linear differential equations; and the relations between the states of activity of neurons. Subsequent chapters describe the properties resulting from feedback within neural masses; the effects of the nonlinearities in the input-output relations of neurons on the behavior of masses; and some inferences concerning the mechanisms of neural signal processing at the level of neural masses. The book is a model for an advanced text in neurophysiology, and some understanding is assumed of the elements of the fields of linear analysis, probability, statistics, theory of potential, neuroanatomy, electrophysiology, neuropharmacology, and experimental psychology.

Book Description
Biographic Memoirs: Volume 67 contains the biographies of deceased members of the National Academy of Sciences and bibliographies of their published works. Each biographical essay was written by a member of the Academy familiar with the professional career of the deceased. For historical and bibliographical purposes, these volumes are worth returning to time and again.

Book Description
Photon correlation is a kind of spectroscopy designed to identify optical frequency shifts and line-broadening effects in the range of many MHz down to a few Hz. The optical intensity is measured in terms of single photon detection events which result in current pulses at the output of photomulti plier tubes. This signal is processed in real time in a special-purpose paral lel processor known as a correlator. The resulting photon correlation func tion, a function in the time domain, contains the desired spectral informa tion, which may be extracted by a suitable algorithm. Due to the non-intrusive nature and the sound theoretical basis of photon correlation, the phenomena under study are not disturbed, and the parameters in question can be precisely evaluated. For these reasons photon correlation has become a valuable and in many instances indispensable technique in two distinct fields. One of these is velocimetry in fluid flow. This includes hydro- and aerodynamic processes in liquids, gases, or flames where the velo city field may be stationary, time periodic, or turbulent, and may range from micrometers per second for motion inside biological cells to one kilometer per second for supersonic flow. The other major field is stochastic particle propagation due to Brownian motion.
