... The top quark, discovered at the Tevatron in 1995 and not long ago re-discovered at the LHC, is strongly coupled to the Higgs sector and therefore expected to be related to electroweak symmetry breaking. ...

Unexpected gamma-ray emission from dwarf galaxy may point to new understanding of dark matter . ... That s why dwarf galaxies are important in the hunt for the dark matter particle. Dwarfs are thought to lack other gamma-ray-producing sources, so a gamma-ray flux from a dwarf galaxy would make a very strong case for dark matter. ...

Next Previous Contents . This means that an interrupt happened that no driver expected. ... In many cases you can safely ignore this error message, especially if it only happens once or twice at boot-time. For boot-time messages, look at the messages which are nearby for a clue as to what is going on. For example, if probing is going on, perhaps a probe for a physical device caused that device to issue an interrupt that the driver didn't expect. ...

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. ...

The Russian Parliament will soon consider a bill that would restructure the Russian space program, 35 years after the launch оf Sputnik. ... But the legislation's most striking and controversial feature is a provision that would ban testing and deployment оf space weapons ? including anti-satellite weapons and space-based missile interceptors. ... A draft bill was written by a group of experts within the Moscow Space Club, several of whom now work on space issues with the Russian Parliament. ...

... From the observed direction of interplanetary magnetic field lines, we believe this field comes from the Sun, carried by magnetic field lines dragged out by the solar wind . ... That is why magnetic field-line loops tend to keep back the solar wind, unlike the outward-bound lines in the "coronal holes" between them. ... The magnetic field at all these points is already so weak that the solar wind overpowers it and shifts its field lines, while its own motion--radially outward--remains unchanged. ...
