Females in some species of Old World monkeys and apes vocalize after copulation, but the function of these vocalizations is not clear. In this article, we examine the hypothesis that copulation calls are a form of postcopulatory female choice. According to this hypothesis, copulation calls are honest signals of fertility (i.e., ovulation) that are used by females to encourage mate guarding by t...

There are two fundamental problems studied by the theory of hamiltonian integrable systems: integration of equations of motion, and construction of action-angle variables. The third problem, however, should be added to the list: separation of variables. Though much simpler than two others, it has important relations to the quantum integrability. Separation of variables is constructed for the SL...

In this paper we compare the Russian National Corpus to a larger Russian web corpus composed in 2014; the assumption behind our work is that the National corpus, being limited by the texts it contains and their proportions, presents lexical contexts (and thus meanings) which are different from those found ‘in the wild’ or in a language in use. To do such a comparison, we used both corpora as tr...

The paper presents experimental results on WSD, with focus on disambiguation of Russian nouns that refer to tangible objects and abstract notions. The body of contexts has been extracted from the Russian National Corpus (RNC). The tool used in our experiments is aimed at statistical processing and classification of noun contexts. The WSD procedure takes into account taxonomy markers of word mea...

BACKGROUND Individual characteristics and socioeconomic strata (SES) are important determinants of health differences. We examine health inequalities in Russia and estimate the association of demography (gender and age) and SES (working status, income, geography of residence, living standard, wealth possession, and durable asset-holding) with perceived health over the period 1994-2012. METHOD...
