... More than 300 surface reconstructions are already known for pure Si surface and Si surface with adsorbate. Study of their properties by the methods of surface physics reveal numerous interesting phenomena including various phase transitions accompanied by changes of Fermi-surface topology, development of the charge-density wave, etc . ... The charge-density wave (CDW) develops in materials with a chain-like crystal structure at temperatures below the Peierls transition temperature. ...

Fibre composite materials were quite well researched in WW 2 and after but failed to make great impact because a stiff and unavailable fibre was lacking. ... The requisite stiffness of composites is known and it is understood how to use it in engineering situations. The problem of toughness of fibre composites is less well understood. Some of the impressive artefacts made from fibre composites are described and their use in the Airbus A380 and Boeing 787 described in a little detail. ...

The direct detection of gravitational waves is one of those events long-expected by physicists that are nevertheless a significant occurrence which excites the world scientific community as if something unexpected has happened. ... Many rumors leaked ahead of the conference, and the fact that something (that is, a signal corresponding to gravitational waves) was discovered by LIGO (Laser Interferometer Gravitational-Wave Observatory) was discussed on the sidelines. ... arXiv:1602.03868 . ...

MAKING THE PROFILES . First of all you are expected to load a FITS file ("FILE"-"LOAD"). ... By pressing the middle button you copy the profile from the first profile window to the second one. ... An example: first integral can correspond to the profile of active region and second integral can correspond to the profile of quiet chromospheric region. ... The second profile (which is subtracted from the first one) you extract after clicking on "SUBTRACT"-"MARK QUIET PROFILE" and marking the region. ...

... Exposure Time Calculator (ETC) . Survey processing . ... VISTA is a 4-m class wide field survey telescope for the southern hemisphere, equipped with a near infrared camera (1.65 degree diameter field of view at VISTA's nominal pixel size) containing 67 million pixels of mean size 0.34 arcsec and available broad band filters at Z,Y,J,H,K s and a narrow band filter at 1.18 micron. A wide field visible camera, if constructed, could also be used on VISTA. ... Tile . ... ESO VISTA Public Surveys . ...
