Science Newsletter of the Faculty fo Physics
This is a new bulletin, which, as we hope, will bring fresh, updated information on scientific news, research activities, and related events in the life of our department to our staff members, undegraduate and graduate students, postdocs, collaborators and partners. We greatly hope that this Science Newsletter will help us to find new partners in research and shorten the way from fundamental research to applications and innovations, from our fundamental discoveries to their successful implementations in not too distant future.
XIV National School-Seminar "Wave phenomena in inhomogeneous media"
The conference papers from the School-Seminar «Waves-2014» will be submitted for publishing in the Memoirs of the Faculty of Physics journal.

The Gardner equation in weakly dispersive limit: evolution of a pulse with a polarity, opposite to the sign of the quadratic nonlinearity
E.А. Rouvinskaya, O.E. Kurkina, A.A. Kurkin, A.R. Giniyatullin
Laboratory of Modeling of Natural and Anthropogenic Disasters, Nizhny Novgorod State Technical University n. a. R. E. Alekseev 24 Minin street, 603950 Nizhny Novgorod, RussiaWe study some peculiarities of the small dispersion limit for the Gardner equation with positive and negative sign of cubic nonlinear term and positive quadratic nonlinear term by numerical modeling of evolution of long bell–shaped pulse with a polarity, opposite to the sign of the quadratic nonlinearity. A statistical and spectral analysis of wave fields is carried out.
