About Zones of Resonant Returns of Asteroid Apophis . ... Asteroid Apophis is one of extremely dangerous NEOs. ... Using analytical and numerical tools, we investigate the loss of precision after the Earth approach in 2029 and the possible approach in 2036. ... Possible trajectories of collisions with the Earth have been found analytically and numerically in this chaotic region. To construct these trajectories we used quasi-random intermediate motions, made up from resonant collision orbits. ...

... We report on a study of the infrared properties of Bi 2 Sr 2 CaCu 2 O 8+ d , Bi 1.66 Pb 0.34 Sr 2 CaCu 2 O 8+ d , and Tl 2 Ba 2 CuO 6+ d crystals at doping levels from underdoped to strongly overdoped. ... While we observe a normal-state gaplike depression in 1/ t ( w , T ) in the underdoped regime, it is not observed in the overdoped regime. While the high-frequency 1/ t ( w , T ) is temperature independent in the underdoped regime, it scales with temperature in the overdoped regime. ...

... The analysis shows, that asteroid ­ rubble pile loses its fast fragments in no time but the retaining fragments forms a compact structure immersed in dust ­ gas atmosphere, created by interaction of interplanetary medium with dispersed product of collisional evolution of asteroid. By interaction of an asteroid ­ rubble pile with interplanetary medium structures asteroid can increase its brightness on account of blowed up dust simulating phenomenon of distant comet's brightening. ...

Distant globular clusters with anomalously small masses. ... We found that 10 metal-poor globular clusters are greately distinguished for anomalously small masses on the "destruction rate-mass" plain. ... Note that 10 distant clusters of anomalously small mass selected by us proved to be younger and with an average metallicity <[Fe/H]> = -1.36 ? ... It looks as if only far from the centre of the Galaxy, conditions are created that lead to formation of globular clusters with anomalously small masses. ...

A very important stage in a story of formation of any new science is the shift from discussion of situation which are possible but do not occur in practice due to some reason to recognition of real phenomena of interest. ... We suggest to consider computer viruses as this new specific form of life which is coming in the contact with our form of life. ... Computer life has been created by human being, the role of independent evolution of computer viruses seems to be still negligible. ...
