... An Interdisciplinary Journal of Nonlinear Phenomena in Complex Systems . ... In this work the approach to recording, storing and associative retrieval of multimedia information is proposed. For this purpose the method for recording and storing the information on the trajectories of the nonlinear dynamic systems is used. Principles of recording, allowing to retrieve the desired record from the database of audio records by an arbitrary piece of the record we are looking for, are proposed. ...

... This thread contains a step-by-step recipe to extract MOS spectra of a point-like source observed in Imaging mode and to create associated response matrices, starting from a calibrated, concatenated event list (either produced with emproc or available as PPS product; here it has the assumed file name MOS.fits ). ... The users should note that the SAS metatask xmmselect allows them to interactively define source and background regions (via ds9) and to run backscale on the fly. ...

LARGE-SCALE PHENOMENA AT THE SUN ASSOCIATED . WITH FILAMENT ERUPTIONS OUTSIDE ACTIVE . ... Considering the 12.09.1999 event as an example, we analyze manifestations of large-scale disturbances associated with coronal mass ejections (CMEs) caused by filament eruptions outside of active regions. ... The filament eruption occurred in relatively weak magnetic fields, but it was accompanied by larger-scale phenomena than flare events do. ...

... This image shows clearly the 3-D structure of this star formation region: a large cavity, created by the radiation pressure from new-born stars located in the brightest area of the image, lies within a huge cloud of dust and gas. Identified as a truly indepedent star cluster, NGC 1980 is associated with this well-studied star formation region, around the brightest star seen at the bottom of this image, Iota Ori. ...

An Observational Program to detect Supernovae in the Virgo Cluster. ... This effort will consist of an observational initiative involving galaxies associated with the Virgo Cluster in search of supernovae (SNe). ... The magnitude limit of this search will concentrate on galaxies brighter than ~14.7v. There are over 2,096 galaxies represented within an area ~140 square degrees, roughly centered on the Virgo Cluster centroid ( [alpha] 12h 25m, and [delta] ~+13 degrees). ...
