We study the two-dimensional, time-dependent magnetohydrodynamics (MHD) of radiation-driven winds from luminous accretion disks initially threaded by a purely axial magnetic field. The radiation force is mediated primarily by spectral lines and is calculated using a generalized multidimensional formulation of the Sobolev approximation. We use ideal MHD to compute numerically the evolution of Ke...

The broad range of subjects represented in this symposium highlight exciting new advances in the field of stream fish community ecology. Some of the chapters expand on themes (e.g., community stability, species interactions) that were represented in the 1987 publication Community and Evolutionary Ecology of North American Stream Fishes edited by W. J. Matthews and D. C. Heins. Others present re...

We apply our technique for indirect imaging of the accretion stream to the polar HU Aquarii, using eclipse prooles observed when the system was in a high accretion state. The accretion stream is relatively luminous, contributing as much or more to the overall system brightness as the accretion region on the white dwarf. We model the eclipse prooles using a model stream consisting of a ballistic...

The instantaneous state of a neural network consists of both the degree of excitation of each neuron, the network is composed of, and positions of impulses in communication lines between neurons. In neurophysiological experiments, the neuronal firing moments are registered, but not the state of communication lines. But future spiking moments depend essentially on the past positions of impulses ...

From 06.05. to 11.05.2007, the Dagstuhl Seminar 07191 Event Processing was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put...
