Underdetermined sets is a new type of data structures (terms) developed in Actor Prolog . ... The point is that an underdetermined set can include some indefinite rest (a tail) like a list in usual Prolog . At the same time, the order of elements of an underdetermined set can be arbitrary one and it does not affect results of unification of underdetermined sets. Moreover, Actor Prolog guarantees that a rest of an underdetermined set never contains elements that are explicitly given in the set. ...

NATURE|Vol 450|15 November 2007 NEW S D. VAN RAVENSWAAY/SPL WHAT TO DO WITH A WORMHOLE OPTICAL CABLES: the wormhole could act as a perfect optical fibre that is invisible from the outside -- but only at a single wavelength, the one the tube is designed to carry. OPTICAL COMPUTERS: dataprocessing elements for conducting logical operations on light signals could be placed inside the wormhole, so that all one would see of the computer is input and output sockets. ...

... The author of the cover picture is Vasilisa Verkhodanova. The picture symbolizes our perception of the world. The modified emblem of the SAO unifying the 6-m optical telescope and the raditelescope RATAN-600 of SAO RAS is placed in the center of the radio galaxy isophotes. From the one hand, we can investigate the properties of radio galaxies with these (and other) telescopes, and try to study physical processes providing their activity. ...

... I studied a variable star with small light variations found on the Kepler satellite. ... I calculated the surface properties and created a hypothesis of a reflecting binary star system to be the cause of this variation in luminosity. ... I can do this by studying the atomic spectra of the star. ... I found the star to be rich in Helium. I then compared the spectrum against model spectra of Helium rich stars to work out the surface gravity, surface temperature and Helium abundance of the star. ...

The Archeops experiment aimed at measuring the cosmic background emitted just after the Big Bang. The study of this radiation is essential to obtain precise information on the evolution of the Universe: density, Hubble constant, age of the Universe.. To achieve this goal, measurements have been done with devices cooled down at 100mK temperature placed at the focus of a warm telescope. ... 28960 visitors . ...
