New and rare species of bryophytes for the territory of St. Petersburg
2012
In total 24 bryophyte species (10 liverworts and 13 mosses) are recorded for the first time for the territory of St. Petersburg and five rare species (Anthoceros agrestis Paton, Fossombronia wondraczekii (Corda) Dumort. ex Lindb., Aloina rigida (Hedw.) Limpr., Dicranella humilis R. Ruthe, Seligeria diversifolia Lindb.) are listed for the territory of St. Petersburg on the basis of old literature data.

Multi-rogue waves solutions: from the NLS to the KP-I equation
2013
Our discovery of multi-rogue wave (MRW) solutions in 2010 completely changed the viewpoint on the links between the theory of rogue waves and integrable systems, and helped explain many phenomena which were never understood before. It is enough to mention the famous Three Sister waves observed in oceans, the creation of a regular approach to studying higher Peregrine breathers, and the new understanding of 2 + 1 dimensional rogue waves via the NLS-KP correspondence. This article continues the study of the MRW solutions of the NLS equation and their links with the KP-I equation started in a previous series of articles (Dubard et al 2010 Eur. Phys. J. 185 247–58, Dubard and Matveev 2011 Natur…
