Russian SHAREABLE DATA CENTER Institute of Solar-Terrestial Physics SB RAS . ... A most promising problem is to investigate the interaction of two VHF powerful radiowave beams in the ionosphere, whose difference frequency is equal to the plasma frequency in some ionospheric area (that is, the difference frequency is taken in the range 1-8 MHz). ... Two-frequency interaction effects are based on radiowave non-linear mixing, which is rather complicated when describing and modelling the experiment. ...

My research is focused on applications of the mathematical language of geometric algebra. ... Geometric algebra can be applied to any subject in mathematics, physics or engineering which is in some part rooted in geometry. ... A black hole has a spectrum of gravitational bound states in much the same manner as the Hydrogen atom. These have only recently been determined, and are contained in the paper Bound States and Decay Times of Fermions in a Schwarzschild Black Hole Background . ...

Dynamical chaos in the problem of magnetic jet collimation O. Yu. ... In the paper of Bisnovatyi-Kogan (2007) magnetic collimation resulting from torsional oscillations of a cylinder with elongated magnetic field and periodically distributed initial rotation around the cylinder axis was considered. ... Space and time periods of oscillations depend on the conditions of jet formation: the length-scale, the amplitude of the rotational velocity, and the strength of the magnetic field. ...

While Apache is for the most part a drop-in replacement for NCSA's httpd, there are a couple gotcha's to watch out for. These are mostly due to the fact that the parser for config and access control files was rewritten from scratch, so certain liberties the earlier servers took may not be available here. ... The basic mod_auth AuthGroupFile -specified group file format allows commas between user names - Apache does not. ... Apache does not implement OnDeny ; use ErrorDocument instead. ...
