An approach to modeling the dynamics of the state of research fronts on the basis of webometric indicators is considered. As a result of the analysis of publication activity, trends in the development of string theory, superstring theory, and M-theory have been revealed. It is shown that the nature of interdisciplinary dependencies for these fields may imply a gradual suppression of well-established theories by newer ones.

This article identifies the role of foreign academies of sciences in generating, disseminating, and using scientific and technical information (STI). The expedience of analytically comparing the websites of these academies by content and characteristics is substantiated. The peculiarities of the legal status of these organizations, as well as their structure and lines of activities, are considered.

The functional features of the websites of the considered academies are analyzed as well as the interface languages, sources, and composition of information posted on these sites about academy members, subordinate organizations/subdivisions, scientific publications and materials published in such publications, scientific events, etc. A detailed analytical comparison is applied to the webometric indicators of the considered sites, including information on inbound, internal, and outbound hyperlinks, site storages, and data on their user traffic. Conclusions are made about the role of these sites in aggregating and disseminating STI, as well as about the usefulness of such sites to Russian researchers and organizations.

In this paper, we investigate a coupling Markov chain for the VKF method, where an excessively long run of the chain is stopped if the number of its steps exceeds the total length of the trajectories preliminarily computed for the chain. For this version of the algorithm, a submultiplicativity lemma is proved. In addition, a theorem on the probability with which the length of the trajectory exceeds a certain threshold is proved by reasoning a la Fekete’s lemma. Finally, we prove that the probabilities of the results yielded by the ordinary and stopped coupling Markov chains differ in terms of the total variation distance by an exponentially small quantity with respect to the number of preliminary runs.

This paper considers the problem of completeness of information transfer during translation; the latter is understood as a type of communicative activity on transposing full-value verbal messages from one culture (and language) into another culture (and language). The main attention is devoted to the translation transformations of compression, or contraction, and extension of information. The viewpoint that the term “translation with elements of localization” is valid is supported. The analysis is based on authentic texts of scientific, technical, and business literature.
