This volume is based on selected and updated papers from the symposium on "Basic Mechanisms of the EEG," which was held under the sponsor ship of the German EEG Society in Hamburg on September 28-29, 1990. The intention of this symposium was to relate recent experimental, clini cal, and neuropathological data on the basic mechanism that underlie the EEG. Although we know much about these mechanisms, there is still much more to be learned. The symposium was partly the continuation of an earlier symposium on "Origin of Cerebral Field Potentials" held in 1979 in Munster under the leadership of one of the present editors (E. -J. Speckmann) and H. Caspers. The present work combines new experimental and clinical results with state-of-the-art reports giving excellent general views. The first chapter presents a historical survey of the roots of current developments in neu rophysiology. It seems that in the near future we may decipher the EEG, which we have considered up to now somewhat as a cryptogram (chap ter 2). After chapter 3-a chapter concerned with more general points of the generation of cortical field potentials-chapters 4, 5, and 6 deal with several aspects and models of interactions and rhythms of cortical neurons. The role of glial cells in cortical electrical field generation is considered in chapter 7. Chapter 8 emphasizes the significance of brain metabolism."

DC-potential changes, comprising fast fluctuations and slow shifts, rep resent objective concomitants of neuronal processes in the brain. They can be recorded not only in animals, but also in humans under various conditions. As far as slow brain potentials are concerned, exciting results have been detected with respect to their correlation to psychophysiolog ical events. Although a large amount of data has been accumulated by psychophysiologists, neurophysiologists, and other scientists involved, the neurophysiological basis of these field potentials is still not clear, and remains controversial. Scientists from European countries participated in an interdisciplinary symposium in the summer of 1990, July 2 to 6, at the Friedrich Schiller University in Jena, which covered the field of slow brain potentials from the psychophysiological to the cellular level, including glial cells and microenvironment. From this conference the idea derived to present an up-to-date overview on important aspects of the field concerned. The Introductory Remarks are given to elucidate what is thought to be a "generator" of slow potentials of the brain. The large number of sources, implications of the "inverse problem" to analyze field potentials are taken into account."

In July of 1989 the 31. International Congress of Physiological Sciences was held in Helsinki. This event in Finland gave us a chance to organize and maintain a satellite symposium on problems of epilepsy from July 4th to 8th, 1989, in Frankfurt-Main. In order to reduce the number of satellite symposia outside of Finland, the president of the IUPS asked different national committees to organize joint meetings. Previously, Dr. Mare~ and Dr. Rokyta had planned to organize a symposium on developmental aspects of epilepsy in Prague, while a meeting in Frankfurt had been planned as an update of a former satellite symposium on physiology and pharmacology of epileptogenic phenomena, held here in 1980. However we were able to combine our efforts by organizing one satellite symposium in Frankfurt entitled: 'PHYSIOLOGY, PHARMACOLOGY and DEVELOPMENT of EPILEPTOGENIC PHENOMENA'. Scientists are generally disappointed about the slow progress in knowledge of their field. We found that by comparing the outcome of the two symposia in 1980 and 1989 a remarkable progress in different, some completely new aspects of the field of experimental epileptogenesis could be realized. Also the new interest in the development of the brain contributed enormously to our understanding of the mechanisms underlying epileptogenic phenomena. We would like to thank all of our colleagues who accepted our invitation to present their recent data and for sending us their manuscripts.

This volume constitutes the refereed proceedings of the 19th International Symposium on Graph Drawing, GD 2010, held in Eindhoven, The Netherlands, during September 2011.
The 34 revised full papers presented together with 3 revised short and 6 poster papers were carefully reviewed and selected from 88 submissions. Furthermore, the proceedings contain the abstracts of two invited talks and to commemorate Kozo Sugiyama and his pioneering research in graph drawing, the proceedings include an obituary. A unique and fun part of the symposium is the Graph Drawing Contest, which is part of the Graph Drawing Challenge. This year was the 18th edition. A report on the contest is included at the end of the proceedings.

Diese Hardcover-Ausgabe ist Teil der TREDITION CLASSICS. Der Verlag tredition aus Hamburg veroffentlicht in der Buchreihe TREDITION CLASSICS Werke aus mehr als zwei Jahrtausenden.

The two-volume set LNCS 9134 and LNCS 9135 constitutes the refereed proceedings of the 42nd International Colloquium on Automata, Languages and Programming, ICALP 2015, held in Kyoto, Japan, in July 2015. The 143 revised full papers presented were carefully reviewed and selected from 507 submissions. The papers are organized in the following three tracks: algorithms, complexity, and games; logic, semantics, automata, and theory of programming; and foundations of networked computation: models, algorithms, and information management.

Sind neuronale Netze das neue Allheilmittel fur Anwenderprobleme, oder sind sie nur des "Kaisers neue Kleider", d.h. leisten sie nur das gleiche wie klassische Statistikverfahren unter einem neuen Decknamen? Dieser Fragestellung soll hier nachgegangen werden, indem ein spezielles, recht leistungsfahiges neuronales Netz, Kohonens selbstorganisierende Karte, betrachtet wird. Verschiedenste Anwender berichten ihre Motivation zur Nutzung dieses Netzes und Erfahrungen mit der selbstorganisierenden Karte in Bezug auf ihr spezielles Problem. Dabei bewahrt sich dieses Netz in den vielfaltigsten Gebieten wie Biologie, Physik, Chemie, Medizin, Linguistik, Sport oder auch kunstliche Intelligenz.
