... We use the graph description of coordinates on Teichmuller spaces of Riemann surfaces with holes due to Penner and Fock. ... The Goldman's Poisson structure can be recovered; its quantum deformation enables us to introduce noncommutative Teichmuller spaces and to construct the quantum mapping class group and quantum modular transformations. Using the geodesic spectral description, we can find a cell decomposition of Teichmuller (and moduli) spaces in the new coordinates. ...

. A regular expression is a concise way of expressing any pattern of characters. You construct a regular expression by combining ordinary characters with one or more metacharacters: characters that have special meaning for the shell . Regular expressions can be used to: . specify filenames . search file contents . change file contents . Commands differ in the range of the regular expressions that they support. Check the manual page for the command for further details.

... A further spin off of this project is that more reliable pointing information for all exposures is provided. In 1995 the ST-ECF introduced, along with the CADC, the re-calibration on-the-fly (OTF) of archived HST exposures. ... By correlating the HST Mission Schedule and the time-tagged engineering telemetry data stream downloaded from HST it is possible to reconstruct with great accuracy the pointing sequence of any given scientific observation. ... taken within the same HST visit . ...

... astro-ph/0003002 We cross-identified the ROSAT Bright Source Catalog (RBSC) and the NRAO VLA Sky Survey (NVSS) to construct the RBSC-NVSS sample of the brightest X-ray sources (~0.1 counts s^{-1} ~= 10^{-12} ergs cm^-2s^-1 in the 0.1--2.4 keV band) that are also radio sources (S ~= 2.5 mJy at 1.4 GHz) in the 7.8 sr of extragalactic sky with |b| > 15deg and DEC > -40deg. ... We used the more accurate radio positions to make reliable X-ray/radio/optical identifications down to the POSS plate limits. ...

... Configuration The dictionary accepts one obligatory parameter - RULES, which has to be set to the file describing parsing rules and output recipes. ... Each non-empty line is either a comment (when started with '#' symbol), or a conversion rule, and in the latter case has to contain whitespace-separated pattern and output recipe. Currently, pattern has to match the _integer_ (one, two or more) number of input tokens; they will be replaced with a single one. ...
