Synchronization and linearity: an algebra for discrete event systems

by François Baccelli, Guy Cohen, Geert Jan Olsder, Jean-Pierre Quadrat , 2001
"... The first edition of this book was published in 1992 by Wiley (ISBN 0 471 93609 X). Since this book is now out of print, and to answer the request of several colleagues, the authors have decided to make it available freely on the Web, while retaining the copyright, for the benefit of the scientific ..."

CoNLL-X shared task on multilingual dependency parsing

by Sabine Buchholz, Erwin Marsi - In Proc. of CoNLL , 2006
"... Each year the Conference on Computational Natural Language Learning (CoNLL) 1 features a shared task, in which participants train and test their systems on exactly the same data sets, in order to better compare systems. The tenth CoNLL (CoNLL-X) saw a shared task on Multilingual Dependency Parsing. ..."

. In this paper, we describe how treebanks for 13 languages were converted into the same dependency format and how parsing performance was measured. We also give an overview of the parsing approaches that participants took and the results that they achieved. Finally, we try to draw general conclusions about multi

Neural Networks as Spatio-Temporal Pattern-Forming Systems

by Bard Ermentrout , 1998
"... Models of neural networks are developed from a biological point of view. Small networks are analysed using techniques from dynamical systems. The behaviour of spatially and temporally organized neural fields is then discussed from the point of view of pattern formation. Bifurcation methods, analytic ..."

Reaction-Diffusion Textures

by Andrew Witkin, Michael Kass - Computer Graphics , 1991
"... We present a method for texture synthesisbased on the simulation of a process of local nonlinear interaction, called reaction-diffusion, which has been proposed as a model of biological pattern formation. We extend traditional reaction-diffusion systems by allowing anisotropic and spatially non-unif ..."

A dynamic model of social network formation.

by Brian Skyrms , Robin Pemantle - Proc. Nat. Acad. Sci. U.S.A. , 2000
"... We consider a dynamic social network model in which agents play repeated games in pairings determined by a stochastically evolving social network. Individual agents begin to interact at random, with the interactions modeled as games. The game payoffs determine which interactions are reinforced, and ..."

players whose locations are close, according to some given spatial data. Biological models in which encounters are governed by spatial structure have become increasingly frequent in the 1990s; see, for example, the work of Durrett, Levin, and Neuhauser (7-9). A similar hypothesis of spatial structure

Systems biology markup language: Level 2 and beyond

by A. Finney, M. Hucka - Biochem. Soc. Trans
"... The SBML (systems biology markup language) is a standard exchange format for computational models of biochemical networks. We continue developing SBML collaboratively with the modelling community to meet their evolving needs. The recently introduced SBML Level 2 includes several enhancements to the ..."

Pattern formation by local self-activation and lateral inhibition

by Hans Meinhardt, Alfred Gierer - BioEssays , 2000
"... In 1972, we proposed a theory of biological pattern formation in which concentration maxima of pattern forming substances are generated through local self-enhancement in conjunction with long range inhibition. Since then, much evidence in various developmental systems has confirmed the importance of ..."

Extracting Biological Information from Full-length Papers

by David P. A. Corney, David T. Jones, Bernard F. Buxton, William B. Langdon, Joanne Charlwood, Peter M. Woollard - Bioinformatics , 2004

Systems biology Advance Access publication June 23, 2011 KEGGtranslator: visualizing and converting the KEGG PATHWAY

by Clemens Wrzodek, Andreas Dräger, Andreas Zell , 2011
"... Summary: The KEGG PATHWAY database provides a widely used service for metabolic and nonmetabolic pathways. It contains manually drawn pathway maps with information about the genes, reactions and relations contained therein. To store these pathways, KEGG uses KGML, a proprietary XML-format. Parsers a ..."

We have developed KEGGtranslator, an easy-to-use stand-alone application that can visualize and convert KGML formatted XML-files into multiple output formats. Unlike other translators, KEGGtranslator supports a
