Tilden) Subject: The Third International BEAM Robot Games: The Third International BEAM Robot Games: Keywords: Yow! The Third BEAM Robot Games are scheduled for March 4-6th, 1994 at the CNE Automotive Building in Toronto as part of the Canadian Home Hobby show. Those that have competed before or sent their Real-mail addresses will receive flyers and details by Real mail. For those that wish further details, contact: Canada First Inc. 797 Don Mills Road, Mony Life Building, 10th floor, Don Mills, Ont., Canada M3C-3S5 Phone: 416/696-5379 Fax: 416/696-7395 They will also be the contacts for the next rulebook, shirts, buttons and upcoming videos. They are, alas, not on Internet yet. If you send this company your real-mail address, you will get a detailed flyer on or before Feb 94. The new BEAM Rules guide will include an expanded get-started section, previous show dossier, where, how, and rule supplements. The Automotive Building is a massive auditorium so hopefully we won't run into space problems like we did at the Science Centre. There is consequently no limit to the size of robots allowed at this show, provided it can be moved by truck. Me, I'm off to Los Alamos NM to carry on my sinister Robotics research, but I will be around for the games. Is all. See you there. Mark W. Tilden ------------------------------ From: Jack Brahan Subject: Artificial Intelligence Symposium ICSRIC94 AI SYMPOSIUM - FIRST ANNOUNCEMENT AND CALL FOR PAPERS 7th INTERNATIONAL CONFERENCE on SYSTEMS RESEARCH INFORMATICS AND CYBERNETICS August 15-21, 1994 Convention Centre - Congresshouse Baden-Baden, Germany Sponsored by: The International Institute for Advanced Studies in Systems Research and Cybernetics and Society for Applied Systems Research The Conference provides an international forum for the presentation and discussion of short reports on current systems research in humanities, sciences and engineering. A number of specialized symposia are held within the Conference to focus on research in computer science, linguistics, cognitive science, psycho-cybernetics, synergetics, logic, philosophy, management, education and related areas. The aim of the conference is to encourage and facilitate the interdisciplinary and trans-disciplinary communication and cooperation amongst scientists, engineers, and professionals working in different fields, and to identify and develop those areas of research that will most benefit from such a cooperation. AI Symposium The 1994 conference will place particular emphasis on Artificial Intelligence. Topics in this Symposium will include, but are not limited to, the following: Knowledge representation, Reasoning, Machine Learning, Fuzzy Logic, Neural Networks, Expert Systems, User Models, Intelligent Tutoring Systems, and Development Methodologies. Papers dealing with theoretical issues or with applications are solicited. In addition to paper presentations, panel sessions on several of these topics are planned. Participants who wish to present a paper are requested to submit a 500 word abstract as soon as possible, but not later than March 15, 1994. (E-mail submissions are preferred.) Notification of acceptance will be sent to authors by April 30, 1994. Full papers, not exceeding 5 single-spaced typed pages, will be required by May 30, 1994.

The system automatically responds to the sender's return path. Hence, it is necessary to send subscription requests and cancellations directly to the listserv at UCSD. (I cannot make modifications to the list ... nor do I have access to the list.) For your privacy, please note that the list will not be rented. If you have problems and require human intervention, contact: The next issue of the reinvented HOTT e-magazine is scheduled for transmission in February. Please forward this announcement to friends and colleagues, and post to your favorite bulletin boards. Our objective is to disseminate the highest quality and largest circulation periodical on the Information Superhighway. I look forward to serving you as HOTT's new editor. Thank you. H O T T U P D A T E I've received a steady stream of superb suggestions over the past weeks regarding the WWW and cross-posting. In response, I plan to launch a WWW/Postscript version of HOTT by 4Q 94. Also, I'll be attempting to launch a gated version to a USENET group. We'll probably call it: bit.listserv.hott or bit.magazines.computing I'm targeting the first issue for a gated USENET group. Further details will be provided in a late January update and the first issue of the e-mail edition. For the protection of your privacy, the HOTT mailing list will NEVER be rented. However, it has become necessary to seek corporate sponsors to help defray costs for subscriptions, reprint permissions, and related expenses (e.g., a new host site -- we're pushing UCSD to its limits!). But we can't get sponsors unless we have at least 100,000+ subscribers. Once we launch a USENET group, we'll be recommending that our Internet subscribers switch to the moderated (and closed) USENET group. Converting most of our Internet subscribers to a USENET will pose much less of a strain on our host system, especially when we exceed 250,000 subscribers. Besides, it's actually easier to read a magazine on a newsreader than it is by e-mail, but it's a lot harder for me to get accurate readership numbers. I'll keep you posted (no pun intended). BTW, we'll continue to offer an e-mail subscription option for those without (or with limited) access to USENET. NEW FEATURES (Consider the following to be a ** very ** preliminary announcement of new features I plan to add to HOTT ... but I can't until we get several sustaining sponsors.) There are numerous features that I plan to add over the next year. First, I want to expand trade magazine coverage to over 200 sources, including at least 30 British trade publications. Also, I want to provide summaries of U.S. and U.K. national news programs, i.e., ABC, CBS, NBC, and BBC. I'd like to transmit selected full-text features from The Los Angeles Times, The Washington Post, The (London) Financial Times, and a Japanese English-language daily (plus article summaries from a few other Japanese English-language dailies; there are a half- dozen English-language dailies published in Japan). Eventually, I'd like to add The New York Times (if I can negotiate a reasonable rate), The San Jose Mercury News, and The Boston Globe. And maybe even Newsbytes and the Japanese English-language equivalent to Newsbytes. I'm currently negotiating with The Los Angeles Times Syndicate for Michael Schrage's "Innovation" column (Michael is willing to comp HOTT on an experimental basis) and I'd like to add a few other syndicated columns. And I have several other surprises! Wish us luck! BTW, information on HOTT archives will be provided in the first issue. -- ************************************************************************* * David Scott Lewis * * Editor-in-Chief and Book & Video Review Editor * * IEEE Engineering Management Review * * (the world's largest circulation "high tech" management journal) * * Internet address: Tel: +1 714 662 7037 * * USPS mailing address: POB 18438 / IRVINE CA 92713-8438 USA * ************************************************************************* ------------------------------ From: "Stevan Harnad" Subject: EEG Models: Chaotic and Linear: PSYCOLOQUY Call for Commentary Note: This is a PSYCOLOQUY Call for Commentators, *not* a BBS Call: You are invited to submit a formal commentary on the target article whose abstract appears below. It has just been published in the refereed electronic journal PSYCOLOQUY. Instructions for retrieving the full article and for preparing a PSYCOLOQUY commentary appear after the abstract. All commentaries are refereed. TARGET ARTICLE AUTHOR'S RATIONALE FOR SOLICITING COMMENTARY The target article attempts to reconcile attractor neural network (ANN) theory with certain current models for the generation of the EEG as a step toward integrating ANN theory with gross observations of brain function. Emphasis is placed on symmetry of cortical connections at a macroscopic level as compared to symmetry at a microscopic level. We hope to elicit commentary on (1) the methodology of the experiments and simulations on which the work is based, (2) any contradictory experimental findings, (3) quantitative methods in anatomy required for further development, (4) other critiques of ANN applicability to global brain function. psycoloquy.93.4.60.EEG-chaos.1.wright Thursday 23 December 1993 ISSN 1055-0143 (53 parags, 12 equations, 3 figs, 62 refs, 1092 lines) PSYCOLOQUY is sponsored by the American Psychological Association (APA) Copyright 1993 JJ Wright, RR Kydd & DTJ Liley EEG MODELS: CHAOTIC AND LINEAR J.J. Wright, R.R. Kydd, D.T.J. Liley Department of Psychiatry and Behavioural Science, School of Medicine, University of Auckland, Auckland, New Zealand ABSTRACT: Two complementary EEG models are considered. The first (Freeman 1991) predicts 40+ Hz oscillation and chaotic local dynamics. The second (Wright 1990) predicts propagating EEG waves exhibiting linear superposition, nondispersive transmission, and near-equilibrium dynamics, on the millimetric scale. Anatomical considerations indicate that these models must apply, respectively, to cortical neurons which are very asymmetrically coupled and to symmetric average couplings. Aspects of both are reconciled in a simulation which explains wave velocities, EEG harmonics, the 1/f spectrum of desynchronised EEG, and frequency-wavenumber spectra. Local dynamics can be compared to the attractor model of Amit and Tsodyks (1990) applied in conditions of highly asymmetric coupling. Nonspecific cortical afferents may confer an adiabatic energy landscape to the large-scale dynamics of cortex. KEYWORDS: chaos, EEG simulation, electroencephalogram, linear dynamics, neocortex, network symmetry, neurodynamics, pyramidal cell, wave velocity. ------------------------------------------------------------------ INSTRUCTIONS FOR PSYCOLOQUY COMMENTATORS Accepted PSYCOLOQUY target articles have been judged by 5-8 referees to be appropriate for Open Peer Commentary, the special service provided by PSYCOLOQUY to investigators in psychology, neuroscience, behavioral biology, cognitive sciences and philosophy who wish to solicit multiple responses from an international group of fellow specialists within and across these disciplines to a particularly significant and controversial piece of work. If you feel that you can contribute substantive criticism, interpretation, elaboration or pertinent complementary or supplementary material on a PSYCOLOQUY target article, you are invited to submit a formal electronic commentary. Please note that although commentaries are solicited and most will appear, acceptance cannot, of course, be guaranteed. 1. Before preparing your commentary, please read carefully the Instructions for Authors and Commentators and examine recent numbers of PSYCOLOQUY. 2. Commentaries should be limited to 200 lines (1800 words, references included). PSYCOLOQUY reserves the right to edit commentaries for relevance and style. In the interest of speed, commentators will only be sent the edited draft for review when there have been major editorial changes. Where judged necessary by the Editor, commentaries will be formally refereed. 3. Please provide a title for your commentary. As many commentators will address the same general topic, your title should be a distinctive one that reflects the gist of your specific contribution and is suitable for the kind of keyword indexing used in modern bibliographic retrieval systems. Each commentary should have a brief (~50-60 word) abstract 4. All paragraphs should be numbered consecutively. Line length should not exceed 72 characters. The commentary should begin with the title, your name and full institutional address (including zip code) and email address. References must be prepared in accordance with the examples given in the Instructions. Please read the sections of the Instruction for Authors concerning style, preparation and editing. PSYCOLOQUY is a refereed electronic journal (ISSN 1055-0143) sponsored on an experimental basis by the American Psychological Association and currently estimated to reach a readership of 36,000. PSYCOLOQUY publishes brief reports of new ideas and findings on which the author wishes to solicit rapid peer feedback, international and interdisciplinary ("Scholarly Skywriting"), in all areas of psychology and its related fields (biobehavioral, cognitive, neural, social, etc.) All contributions are refereed by members of PSYCOLOQUY's Editorial Board. Target article length should normally not exceed 500 lines [c. 4500 words]. Commentaries and responses should not exceed 200 lines [c. 1800 words]. All target articles, commentaries and responses must have (1) a short abstract (up to 100 words for target articles, shorter for commentaries and responses), (2) an indexable title, (3) the authors' full name(s) and institutional address(es). In addition, for target articles only: (4) 6-8 indexable keywords, (5) a separate statement of the authors' rationale for soliciting commentary (e.g., why would commentary be useful and of interest to the field? what kind of commentary do you expect to elicit?) and (6) a list of potential commentators (with their email addresses). All paragraphs should be numbered in articles, commentaries and responses (see format of already published articles in the PSYCOLOQUY archive; line length should be < 80 characters, no hyphenation). It is strongly recommended that all figures be designed so as to be screen-readable ascii. If this is not possible, the provisional solution is the less desirable hybrid one of submitting them as postscript files (or in some other universally available format) to be printed out locally by readers to supplement the screen-readable text of the article. PSYCOLOQUY also publishes multiple reviews of books in any of the above fields; these should normally be the same length as commentaries, but longer reviews will be considered as well. Book authors should submit a 500-line self-contained Precis of their book, in the format of a target article; if accepted, this will be published in PSYCOLOQUY together with a formal Call for Reviews (of the book, not the Precis). The author's publisher must agree in advance to furnish review copies to the reviewers selected. Authors of accepted manuscripts assign to PSYCOLOQUY the right to publish and distribute their text electronically and to archive and make it permanently retrievable electronically, but they retain the copyright, and after it has appeared in PSYCOLOQUY authors may republish their text in any way they wish -- electronic or print -- as long as they clearly acknowledge PSYCOLOQUY as its original locus of publication. However, except in very special cases, agreed upon in advance, contributions that have already been published or are being considered for publication elsewhere are not eligible to be considered for publication in PSYCOLOQUY, Please submit all material to psyc@pucc.bitnet or Anonymous ftp archive is DIRECTORY pub/harnad/Psycoloquy HOST ------------------------------------------------------------ To retrieve the file by ftp from a Unix/Internet site, type either: ftp or ftp When you are asked for your login, type: anonymous Enter password as per instructions (make sure to include the specified @), and then change directories with: cd /pub/harnad/Psycoloquy/1993.volume.4 To show the available files, type: ls Next, retrieve the file you want with (for example): get psyc.93.4.60.EEG-chaos.1.wright [or you can abbreviate with: mget *wright When you have the file(s) you want, type: quit In case of doubt or difficulty, consult your system manager.

EUROPEAN CONFERENCE ON ARTIFICIAL LIFE ECAL95 Granada, Spain, 4-6 June, 1995 It is a pleasure to announce the forthcoming 3rd European Conference on Artificial Life (ECAL95). Despite its short life, Artificial Life (AL) is already a mature scientific field. In trying to discover the rules of life and extract its essence so that it can be implemented in different media, AL research has led us to a better understanding of a large set of interesting biology-related problems, such as self organization, emergence, origins of life, self-reproduction, computer viruses, learning, growth and development, animal behavior, ecosystems, autonomous agents, adaptive robotics, etc. The Conference will be organized into Scientific Sessions, Demonstrations, Videos and Comercial Exhibits. Scientific Sessions will consist of Lectures (invited), Oral Presentations, and Posters. The site of ECAL95 will be the city of Granada, located in the south of Spain, in the region of Andalucia. Granada was the last moors site in the Iberic Peninsula, and it has the inheritance of their culture with the legacy of marvelous constructions such as the Alhambra and the Gardens of Generalife. ECAL95 will be organized in collaboration with the International Workshop on Artificial Neural Networks (IWANN95) to be held at Malaga (Costa del Sol, Spain), June 7-9, 1995.
