... The CME was formed at a distance of 0.2 0.5 R from the Sun's surface as a U-shaped structure, which was observed both in the 171 њ A images and in white-light. ... When the CME passes from TESIS Fe 171 њ to A LASCO C2 field of view, we see complete correspondence between the bright structures on the TESIS and LASCO images (see Figure 4b,c). Since bright structures on LASCO images are density structure, then the CME on TESIS Fe 171 њ images is also a density structure. ... Figure 2. ...

... The complexity of inversion of Goldreich's function by backtracking algorithms. ... In 2005 M. Alekhnovich, E. Hirsch and D. Itsykson proved the exponential lower bound on the complexity of inversion of Goldreich's function based on linear predicate and random graph by myopic bactracking agorithms. ... Motivated by applications to string algorithms, we introduce the following subclass of Monge matrices: a matrix is called unit-Monge, if its density matrix is a permutation matrix. ...

The astronauts moved out of the stricken Command Module and into the cramped quarters of the Lunar Module. The Lunar Module, built for the short trip for two people to land on the moon, would serve as the lifeboat for a four-day journey for three people. ... Lunar Module pilot. ...

In the regular experiments carried out with the RAS radio telescopes at Pushchino during 1999-2002, the study of the radial dependence of scattering of compact natural radio sources was extended to remote regions of the solar plasma environment. ... The stream in the transalfvenic region displays the same typical radial structure as observed in the transonic region, i.e., the existence of a "precursor" - a narrow band of reduced scattering preceding a wide region of enhanced scattering. ...

Super Rocket Targets . NPO MOLNIYA has been designing rockets-targets for over 30 years using the great experience in crea-ting anti-aircraft guided rockets (AGR) for C-25M. On the basis of B-300 anti-aircraft rockets which expired their service life, there were designed, tested and put into the serial production the following types of the rocket - ... The analogue of this system successfully passed the state tests with the ZVEZDA-4 rocket-target. ...

... Moon Phase below . ... ARTICLE: Why the moon always shows us the same face . ... Before you continue reading, you should know that this was not always the case, i.e. the Moon once was rotating with respect to the Earth, so that on every night a terrestrial observer (if there was one, because this was long, long before mankind appeared on our planet, and even before any major animals had appeared) saw another face of the Moon. ... Figure 1 (not to scale) shows how we can imagine the system Earth-Moon...
