Autor: Giovanni Denaro, Davide Valenti, Bernardo Spagnolo, Gualtiero Basilone, Salvatore Mazzola, Salem W Zgozi, Salvatore Aronica, Angelo Bonanno

Publikováno v: PLoS ONE, Vol 8, Iss 6, p e66765 (2013)

A stochastic advection-reaction-diffusion model with terms of multiplicative white Gaussian noise, valid for weakly mixed waters, is studied to obtain the vertical stationary spatial distributions of two groups of picophytoplankton, i.e., picoeukaryo

A quantum spin approach to histone dynamics

Autor: Gils, C., Wrana, J. L., Salem, W. K. Abou

Post-translational modifications of histone proteins are an important factor in epigenetic control that serve to regulate transcription, depending on the particular modification states of the histone proteins. We study the stochastic dynamics of hist

Colliding solitons for the nonlinear Schrodinger equation

Autor: Salem, W. K. Abou, Froehlich, J., Sigal, I. M.

We study the collision of two fast solitons for the nonlinear Schr\"odinger equation in the presence of a spatially adiabatic external potential. For a high initial relative speed $\|v\|$ of the solitons, we show that, up to times of order $\log\|v\|

On the theory of resonances in non-relativistic QED and related models

Autor: Salem, W. K. Abou, Faupin, J., Froehlich, J., Sigal, I. M.

We study the mathematical theory of quantum resonances in the standard model of non-relativistic QED and in Nelson's model. In particular, we estimate the survival probability of metastable states corresponding to quantum resonances and relate the re
