... Toward this goal, the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey -III (SDSS-III) has measured slight recurring density enhancements in galaxy densities up to six billion light years away ( redshift 0.7), when the universe was about half its current age. ... BOSS's measurements of this size scale indicate a strong universe component of dark energy , and so bolsters previous indications of this unusual composition. ... NASA Official: Jay Norris. ...

Irregular phenomena in the Earth Pole oscillation process and temporal variations of geopotential Valery Bondarenko, Vadim Perepelkin s The observed irregular phenomena in the Earth Pole oscillation process are very variety. ... These phenomena indicated in the IERS data are the "abnormal" fluctuation of the Earth Pole coordinates which owing to changing of the geodynamical parameters gives negative result in interpolation and forecast of the first approximation mathematical model. ...

... The curve of the photoconductivity of n -GaAs versus the magnetic field during monochromatic infrared illumination reveals oscillations consisting of two series of extrema which are periodic along the inverse-field scale. One series of extrema stems from the nonmonotonic field dependence of the impurity magnetoabsorption coefficient, the other stems from a sharp step in the distribution function of nonequilibrium electrons.

. The Oscillation Project with Emulsion-tRacking Apparatus (OPERA) is an experiment to test the phenomenon of neutrino oscillations. It exploits CERN Neutrinos to Gran Sasso (CNGS), a high-intensity and high-energy beam of muon neutrinos produced at the CERN Super Proton Synchrotron in Geneva, Switzerland, and pointing to the Laboratori Nazionali del Gran Sasso (LNGS) underground laboratory, 455 miles (730 kilometers) away at Gran Sasso in central Italy.

Dynamical chaos in the problem of magnetic jet collimation O. Yu. ... In the paper of Bisnovatyi-Kogan (2007) magnetic collimation resulting from torsional oscillations of a cylinder with elongated magnetic field and periodically distributed initial rotation around the cylinder axis was considered. ... Space and time periods of oscillations depend on the conditions of jet formation: the length-scale, the amplitude of the rotational velocity, and the strength of the magnetic field. ...
