. The command ls -a . lists all the "hidden" files that begin with a '.' (dot). All other files and directories are also listed. This type of file is often created by you, the user, to hold commands that customise how a particular program is to work. These files are usually held together in your home directory. Every directory has two dot files, '.' and '..' which can be used in a shorthand way to refer to the current directory '.'(dot) and the parent directory of the current directory '..' (dot dot).

... Determining the nominal roll angle for stable intervals . ... We found the necessary information in a file 'rh*.ao', which has a binary extension table for each obi. ... Unlike the question of determining the nominal roll angle, we know of no a priori indication of this problem (although the guide star configuration may be the cause, or at least associated with this condition): it is necessary to examine the source position for each obi. ... The guide star record is at the end of the 'anc file'. ...

... Solar flare activity is produced by the processes of accumulation and release of energy in an active region. ... In the framework of study of solar active regions, producing powerful flares the researchers from the RATAN-600 radio telescope have detected sources with features in the form of a sharp drop in the intensity of polarized radiation in various parts of the recorded frequency range (2-16GHz), sometimes changing the sign of polarization. ...

Hochschild-Witt cohomology and a cristalline analog of the Tate Conjecture Dmitry Kaledin Summary We define a non-commutative analog of the de Rham-Witt complex and cristalline cohomology for arbitrary associative unital algebras over a finite field. We generalize this to DG algebras, so that in particular, we can recover the usual cristalline cohomology and de Rham complex of smooth algebraic varieties (in the same sense as peridoci cyclic homology recovers de Rham cohomology). ...

Next: ZGSC (Compressed GSC) and XSKYMAP . ... This is a preliminary report on an investigation of the quality and properties of plates digitized during creation of the Guide Star Catalog (GSC). The results will be vital for reclassifying GSC objects. ... Many objects are measured on more than one plate, and thus have multiple catalog entries. ... Among the shortcomings of the GSC are: biased magnitudes and incorrect classifications for certain objects, presence of artifact objects. ...

Planetary Formation is though to occur via an accretion process in a disk of gas and dust that settles into orbit about the host star. ... The identification of dusty disks around young stars would constitute excellent evidence that this process is common and that planetary formation is a natural consequence of star formation. ... This discovery, courtest of Dr. C. O'Dell at Rice University, is consistent with previous discoveries of dusty disks around nearby stars. ...
