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. ...

... 8, ``Celestial Mechanics'', 2002 Rotation theory of celestial bodies: dynamical relations of the pole motion and nutation Yu. ... Problem By construction Earth rotation theory the studies of the precession--nutation motion and pole motion are considered usually separately. ... The angle Q between the polar axis of inertia and axis of rotation is small (of order 10 \Gamma6 ). ... The perturbation theory of the Earth rotation has been constructed in the elastic Andoyer and angle--action variables. ...

... According to the current estimates, a few percent of Main Sequence B5-F5 stars reveal strong surface magnetic fields reaching the values of tens of kilogauss, which is an order of magnitude greater than the maximal magnetic field in sunspots. ... An important direction in the study of magnetic stars is the study of binary and multiple systems with magnetic components using the techniques of spectroscopy and high angular resolution interferometry. ...

... We have measured this "redshift" for the pink black holes, and allowed for it in our calculations. ... We see this effect in the emission from gas around these pink black holes, but it is far too small an effect to account for the pinkness. Thus the swirling motions of gas around or into the black holes cannot produc the colour. ... At first we thought that these things were normal blue black holes hidden behind clouds of interstellar dust, that absorbed the blue light and made them appear pink. ...

... According to the big bang theory, huge amounts of energy were released, giving rise to matter, antimatter and dark matter. ... The Big Bang Theory has enabled scientists to make certain predictions. ... These particles are the building blocks of matter, antimatter and dark matter. ... This could theoretically happen if the hydrogen was shockheated to over 100000 C. The Big Bang Theory is only a theory and so there is no concrete evidence to suggest that it is entirely correct. ...

... Imagine that for every pixel in the color image, you take its luminance value (that's how bright it appears). ... In the end, you will have a histogram which counts how many times each luminance value appears in the image (that histogram can be used to analyze the distribution of the luminance values in the image). ... For the watermark effect, we want to use the same value that we used in the Stretch Contrast step, so that the lightest color will be in fact white (255), and nothing will get clamped...

Dear Colleague, We would like to inform you that the 7-th edition of the International Workshop "Lie Theory and Its Applications in Physics" shall be held in Bulgaria (resort "Chaika", near Varna, on the Black Sea), 18 - 24 June 2007. ... The first three workshops were organised in Clausthal (1995,7,9), the 4th was part of the 2nd Symposium 'Quantum Theory and Symmetries' in Cracow (2001), the 5th was organised in Varna (2003) http://theo.inrne.bas.bg/~dobrev/LT-5/ . ...
