. Comment on J2243-2544 . The jet extends in the opposite direction to that shown by Shen et al. (1998) at 5 GHz with about 2 times higher resolution than our image. The structure we see is confirmed by the 2.3 and the 8.4 GHz images from the VLBA Calibrators database. VLBApls home page . Last modified: 16 Oct 2000

The first persistent Web agent that we have created on Actor Prolog is a program that collects information about research groups that develop Prolog and projects in the field of logic programming. The agent looks through a given list of Web sites and calculates some attributes of the sites: the date of recent modification, total size, the number of figures, the number of outside links, the number of error links, the number of given keywords, etc. ... http://www.cplire.ru/Lab144/space/prolog.html . ...

This artistically modified image of the local galaxy Arp 220, captured by the Hubble Space Telescope, helps illustrate the Herschel results. The bright core of the galaxy, paired with an overlaid artist's impression of jets emanating from it, indicate that the central black hole's activity is intensifying. As the active black hole continues to rev up, the rate of star formation will, in turn, be tamped down in the galaxy. ...
