Simulating information creation in social Semantic Web applications cs.CE Appropriate ranking algorithms and incentive mechanisms are essential to the creation of high-quality information by users of a social network. However, evaluating such mechanisms in a quantifiable way is a difficult problem. Studies of live ...

Composition operators on Bergman-Orlicz spaces on the ball math.FA math.CV We give embedding theorems for weighted Bergman-Orlicz spaces on the ball and then apply our results to the study of composition operators in this context. As one of the motivations of this work, we show that there exist some weighted Bergma...

Radio emission from dark matter annihilation in the Large Magellanic Cloud astro-ph.HE The Large Magellanic Cloud, at only 50 kpc away from us and known to be dark matter dominated, is clearly an interesting place where to search for dark matter annihilation signals. In this paper, we estimate the synchrotron emi...
