. Comment on J0126-0123 . No detection: this object has been studied with the Molonglo telescope at 408 MHz (Schilizzi & McAdam 1975) as a source with a size between 2 and 5 . It is near an Abell cluster (Owen & Ledlow 1997). The data could be confused with a strong radio source (3C 40) identified with a pair of galaxies at z=0.018, 170" from our field center.

Titles and abstracts. ... Bernard Leclerc; On the dual canonical basis (old and new) . Around 1991, Lusztig, motivated by earlier works of Gelfand and Zelevinsky, introduced a "canonical basis" of the coordinate ring C[N] of the maximal unipotent subgroup N of a simple algebraic group G. This basis was in fact the specialization as q tends to 1 of the dual canonical basis of the quantum enveloping algebra U_q(n) (where n = Lie(N)). ...

... THE SIMPLEST MODEL. ... 13, Moscow 119992, Russia E-mail: san@sai.msu.ru Abstract: The analysis of the simplest model shows that an asteroid ­ rubble pile evolves, depending on the parameter V2d (where V is the average velocity of fragments and d is the average distance between fragments), either as a conglomerate of "independent mutually gravitating clusters" (when V2d < fm, where f is the gravitational constant and m is the average mass of a fragment) or as a "receding cluster" (when V2d > fm). ...
