We give strong bounds for the rate of convergence of the regenerative process distribution to the stationary distribution in the total variation metric. For this aim we propose a new modification of the coupling method which we call stationary coupling method. Use of this stationary coupling method improves the classic results about the convergence rate of the distribution of the regenerative process in the case of a heavy tail. Also this method can be applied for obtaining the bounds of the rate of the convergence for the queueing regenerative processes. © Springer International Publishing AG 2016.

Nutrition is an important indicator of quality of life, an element of national security. The article reviews the formation of the food consumption geography. The differences in food consumption among Russia's regions are shown in the dynamics from 1990 to 2013. They are caused by the influence on food patterns of such factors as natural conditions, level of regional socioeconomic development, local traditions associated with the agricultural profile of an area, living standards, ethnic nutrition traditions, etc. The well-being of regions with higher food consumption levels depends mainly on economic conditions or on favorable natural living conditions. The following trends have been identified: an increase in consumption of vegetables in most regions; a decrease in consumption of dairy products in Russia in general, and especially in regions with traditional dairy farming; and a significant increase in consumption of potatoes and bread in the North Caucasian republics. The paper represents the results of a food pattern cluster analysis of Russia's regions in 1990 and 2013. © 2016 Pleiades Publishing, Ltd.

We introduce the notion of a pseudotoric structure on a symplectic manifold, generalizing the notion of a toric structure. We show that such a pseudotoric structure can exist on toric and nontoric symplectic manifolds. For the toric manifolds, it describes deformations of the standard toric Lagrangian fibrations; for the nontoric ones, it gives Lagrangian fibrations with singularities that are very close to the toric fibrations. We present examples of toric manifolds with different pseudotoric structures and prove that certain nontoric manifolds (smooth complex quadrics) have such structures. In the future, introducing this new structure can be useful for generalizing the geometric quantization and mirror symmetry methods that work well in the toric case to a broader class of Fano varieties. © MAIK/Nauka 2010.

The article describes the formation of surface topography in combined finishing machining. Use of combined machining can achieve a better quality of the resulting surface. Multiple studies have helped to formulate the main provisions and recommendations regarding the determination of appropriate machining parameters, selection of cutting parameters and the environmental requirements the cutting tool in use should meet. However, many questions on the quality of, and opportunities for combined shaping methods have not yet been studied. © 2016 The Authors.

Localized waves near the stress-free surface or the free edge of a solid with a thin nematic coating are investigated. The nematic media is described using an approximate linear low-frequency model. Being a non-traditional material this medium possesses a strong anisotropy of elastic and viscous properties and some additional freedom caused by the long polymer chain and molecules. As shown, the specific wave phenomena, observed earlier in the infinite nematic media, in the case of a coating with finite thickness lead to the appearance of the quasi-resonance zones where the phase speed and the attenuation of waves in heterogeneous composites are strongly perturbed. © 2011 SAGE Publications.

At present time the growth of high speed train traffic takes part in Russian Railways, especially in the European part of the country. In this connection, routes of freight traffic have been changed. The load from freight trains on lines with embankments based on weak foundations (peat foundations) has been increased. The evaluation of efficiency of reinforcement of the peat foundation with wooden piles applied for repair of the subgrade was obtained by centrifugal modeling. The results were compared with modeling of embankments without reinforcement. As the prototype there were used embankments on Obozerskaya-Malenga line (northern part of Russia, Arhangelsk region). Physical centrifugal modeling was obtained by wooden pile construction for prototype scale: length of piles-6.5 m and diameter 0.3 m (joined in the top) with small sandy berm. Two series of experiments were performed: for two rows of piles and for four rows of piles. In the paper there are presented data of these centrifuge tests and construction sites observing for better analyzing efficiency of these technical decisions. © 2014 Taylor & Francis Group.

Fundamentals of the new theory for the processes of transition from deterministic state to the chaos state (turbulence) for non-isothermal flows are presented. According to this theory, systems of stochastic equations of energy, momentum and mass are applied for non-isothermal flows. Then the analytical dependence for estimation of the value of the critical Reynolds number and the value of the critical point of regime change for non-isothermal and compressible flows are written. As an example, consider the classic flow of a Newtonian medium in the circular smooth tube. The values of the critical point of the beginning of the transition from laminar (deterministic) to turbulent motion for non-isothermal flows in the pipe are predicated. It is shown, that predicated values of the critical Reynolds numbers are in satisfactory agreement with the classical data. © 2014 Artur V. Dmitrenko.

Contributing to the European Research Area in surface transport to strengthen the competitiveness of the European surface transport sector. This will be achieved by using the excellent EURNEX competence to provide research excellence capabilities to European Small and Medium Size Enterprises (SMEs). Furthermore the cooperation with research excellencies from non EU countries will stimulate research that is of mutual interest and strengthen the European as well as non European research excellencies. EURNEX, the European Rail Research Network of Excellence, started on 01 January 2004 and has been granted for 4 years with 6 Mio within the 6th Framework Programme of EC. It involves 66 research institutes from 20 European countries and the associations of industry and operators UNIFE, UIC and UITP. More than 80 % of the members cover not only the rail research domain but surface transport. EURNEX supports the aims of the EC to see an interoperable and harmonised European rail system contributing to co-modality and a strong internationally competitive European railway industry by integrating the fragmented research, sharing knowledge and coordinating current research. The main benefits for the integration of non EU researchers in EURNEX are the scientific exchange on an international level, the training of junior scientists and researchers using the EURNEX assets, the identification of research areas that are of mutual interest, and the solving of problems in the international railway sector with European know how. The main benefits, that SMEs contributing as associated partners in EURNEX can gain, are an overview of the state of the art of the surface transport sector as a whole as well as specific topics, an insight in current research trends, an evaluation of their individual know how (respecting sensitive information), and an access to excellent research capabilities and test facilities.

We show that exotic Lagrangian tori constructed by Chekanov and Schlenk can be obtained for a large class of toric manifolds. For this, we translate their original construction into the language of pseudotoric structures. As an example, we construct exotic Lagrangian tori on a del Pezzo surface of degree six. © 2012 Pleiades Publishing, Ltd.

The rapid development of Asian economies, particularly China, India and Russia has dramatically increased the trade volumes between Europe and Asia, with the largest trading partners of Europe actually being located in Asia. Nowadays, the most important trade loads are being transported between the two continents by sea. Railway transport, using the existing and new land routes for the Trans-Eurasian land bridge presents a viable alternative to the maritime routes, which is gaining significant momentum. Due to the origins and current nature of this rail land bridge, numerous issues need to be resolved to bring the system to a modern state of infrastructure, services and operations. Furthermore, to build the capacity to fully exploit the systems potential adaptation of new technologies, interoperability solutions and optimized operations should be considered. To support this objective, NEAR2 proposed the development of a Rail Research Network, drawing knowledge and expertise form leading institutions and researchers from both continents. The project capitalizes upon the existing structure and leverages the achievements of the existing European Rail Research Network and builds upon the reservoir of expertise of the proposed project partners gleaned from the most relevant past and on going research projects and other activities. The Network aims to become the resource arm of the relevant industry. NEAR2 will establish a unique, international, interdisciplinary research capacity with the goal of contributing in advancing a major sector of the regions economy, as well as broaden the knowledge basis of the railway research and practice.
