| Abstract: | We show that for any random matrix  with independent mean zero entries ![\begin{displaymath}\mathbf{E}\Vert(X_{ij})\Vert\leq C \Big(\max_{i}\sqrt{\sum_{j... ...} X_{ij}^{2}}+ \sqrt4]{\sum_{ij} \mathbf{E} X_{ij}^{4}} \Big),\end{displaymath}](http://www.ams.org/proc/2005-133-05/S0002-9939-04-07800-1/gif-abstract0/img2.gif) where  is some universal constant. |
