We study the problem of quantization of discrete probability distributions, arising in universal coding, as well as other applications. We show, that in many situations this probl...
For finite-size scaling studies of second-order phase transitions the critical energy range of interest is usually larger than the energy range covered by a canonical Monte Carlo ...
We consider the general relay channel. For this setup, the best achievability result was derived by Cover and ElGamal, in theorem 6 of their paper from 1979. In this work we apply...
Abstract. We outline a general theory of graph polynomials which covers all the examples we found in the vast literature, in particular, the chromatic polynomial, various generaliz...
We consider a scenario where an attacker is able to receive a stegosignal only over a Gaussian channel. But in order to provide security of this channel noise
