This paper extends the concept of betweenness centrality based on Kirchhoff’s law for electric circuits from centrality of nodes to centrality of edges. It is shown that this new measure admits analytical definition for some classes of networks such as bipartite graphs, with computation for larger networks. This measure is applied for detecting community structure within networks. The results of numerical experiments for some examples of networks, in particular, Math-Net.ru (a Web portal of mathematical publications) are presented, and a comparison with PageRank is given. © Springer International Publishing Switzerland 2016.

International Game Theory Review | Year: 2016

This paper studies a game-theoretic model of best choice with incomplete information. In this model, players observe a sequence of incoming objects each described by two random quality components. The first component is announced to players and the other one is hidden. Players choose an object based on known information about it. The winner is the player having a higher sum of the quality components than the opponents do. The optimal strategies of the players and their payoffs in the game are derived. © 2016 World Scientific Publishing Company. Source

The regularities of changes in the optical properties of crystals of Bi2Te3-Sb2Te3 solid solutions in the range of the effects caused by free-carrier plasma oscillations at a variation in the ratio of Bi2Te3 and Sb2Te3 components are investigated. It is established that, when the Sb2Te3 content in a solid solution exceeds 80 mol %, the fundamental absorption edge undergoes plasma screening. Doping a Sb2Te3 crystal with tin increases the free-carrier concentration and plasma frequencies, thus enhancing the screening effect, whereas introduction of 0.1 mol % selenium reduced the plasma frequency and thus removes the fundamental-absorption-edge screening. © 2014, Pleiades Publishing, Ltd.

The paper discusses efficiency of mineral and raw materials development projects and coordina- tion of the long-term interests of public and private investors in cross-border Russian-Chinese cooperation activities. A series of empirical studies on development in the border regions of Russia's Far East over the last decades have signaled that these territories really faced risks of lagging behind. The problem associated with the provision of national interests within Russian-Chinese cooperation was illustrated on the example of two projects to be implemented in Zabaikalsky krai. The projects were evaluated using scenario analysis based on the author's methods. The estimates show that the interest of an investor, the fulfillment of Russia's legislative procedures, and the presence of market demand for products cannot always guarantee the procurement of Russia's national interests and "symmetrical" outcomes in the framework of Russian-Chinese cooperation. Searching for a compromise of interests, a methodical scheme has been offered to provide sufficient levels of sustainability and profitability for the Russian party in joint cross-border projects. © Pleiades Publishing, Ltd., 2013.

This paper considers a best-choice game with incomplete information associated with the job search problem. Players (experts) observe a sequence of independent identically distributed random variables (xi, yi), i = 1 . . . , n, which represent the quality of incoming objects. The first component is announced to the players and the other one is hidden. The players choose an object based on known information about it. The winner is the player having a higher sum of the quality components (total quality) than the opponent. And finally, the optimal strategies of the players are derived. © 2015 The Authors.
