... Early studies of PMS stars focused on T associations, especially Taurus-Auriga. However, one might expect low mass star formation to be different in OB associations. ... He identified Orion OB1a as the stars northwest of the belt. Orion OB1b is composed of the stars near the belt, including the belt stars and Orionis. ... He finds no perceptible distance change within the Orion OB1b association and finds the distance modulus to be 7.8 and 7.9 for Orion OB1a and OB1b respectively. ...

... The procedure of radiometer signal integration can be considered as a sort of reducing dimension of the initial sampling space, where the samples are the result of analog-to-digital conversion. ... The probability distribution of the signal and spikes is completely known. ... The quality of the considered algorithm could be also illustrated by Figure 2 . ... One could see the considered adaptive algorithm is preferable even by low degree of compression, because all spikes have been depressed. ...

... At 37m long and over 4m across, Polyus-Skif was an enormous 80 tonne spacecraft which possessed its own space resupply tug to control its orbit once in space. Too heavy to be carried to space on the back of the USSR?s standard heavy-lift launcher, the Proton rocket, its launch became a major event for the cosmonautic world, as it was to have been the first object to be taken into space on the Soviet UnionтАЩs new and most powerful ever launch vehicle, the superheavy launch system, Energia . ...
