Observation of two-dimensional lattice interface solitons

We report on the experimental observation of two-dimensional solitons at the interface between square and hexagonal waveguide arrays. In addition to the different symmetry of the lattices, the influence of a varying refractive index modulation depth is investigated. Such variation strongly affects the properties of surface solitons residing at different sides of the interface.Comment: 14 pages, 5 figures, to appear in Optics Letter

Bloch wavepacket control in truncated modulated optical lattices

We study the reflection of Bloch wavepackets at the interface of optical lattice possessing a shallow longitudinal out-of-phase refractive index modulation in adjacent waveguides. We show that the relation between the transmitted and reflected energy flows can be efficiently controlled by tuning the frequency and the depth of the modulation. Thus, complete beam reflection may be achieved for a set of resonant modulation frequencies at which light tunneling between adjacent guides of modulated lattice is inhibited.Comment: 14 pages, 4 figures, to appear in Optics Letter

Defect equilibrium in PrBaCo2O5+δ at elevated temperatures

A defect equilibrium model for PrBaCo2O5+δ is suggested based on oxygen non-stoichiometry data. The model includes reactions of oxygen exchange and charge disproportionation of Co3+ cations. The respective equilibrium constants, enthalpies and entropies for the reactions entering the model are obtained from the fitting of the experimental data for oxygen non-stoichiometry. The enthalpies of oxidation Co2+→ Co3+ and Co3+→Co4+ are found to be equal to 115±9 kJ mol-1 and 45±4 kJ mol-1, respectively. The obtained equilibrium constants were used in order to calculate variations in concentration of cobalt species with non-stoichiometry, temperature and oxygen pressure. © 2013 Elsevier Inc

The political process of modern russia and the concept of institutional matrices

The article discusses the features of political process in Russia from the perspective of institutional matrices theory by S.G. Kirdina. During the description of contemporary political process in Russia, the authors examine its dependence on Y-matrix, the development and operation of its basic institutions. The task of these institutions influence on the political process of Russia development is set as the main purpose of the study. The following hypothesis is put forward in order to achieve this goal: is the influence of Y-matrix basic institutions an insurmountable obstacle for the modern Russian democracy development. The work includes the following methods and techniques as the methodological basis of research: neoinstitutional, systemic and structural-functional approaches, sociological, historical and logical methods, as well as the analysis of basic and variable factors influencing the political process of modern Russia. We came to the following conclusions after research: social institutions are the support of any society, the structure of the basic fundamental institutions forms a special matrix where the basic institutions are in a mutual accordance and close cooperation. Economy, politics, ideology are the most important aspects among these institutions. A society cannot be burdened with institutions, which are not inherent to it. It is impossible to replace one institution by another one, even if its effectiveness is discovered hardly in another country, but which does not meet the entire system of complementary, mutually relevant, harmonious and complementary rules, norms and institutions. The characteristic features of the modern political process in Russia: the strengthening of the unitary-centralized political system, the increase of a state role and its paternalistic nature, the imitative nature of democratic reforms, the reduction of public policy field, the power distancing from society, the growth of bureaucracy, etc. All these trends are consistent with the basic provisions of institutional matrix theory, the basic institutions of Y- institutional matrix, and can be projected on the modern Russian political process

State regional policy in modern russia: Problems and trends of development

© Medwell Journals, 2016.This study is devoted to research of the current conditions of the state regional policy in the Russian Federation. Despite the importance of the problems of regional policy in Russia, it has not become systemic to this day. "The Regional policy and federal relations" Program adopted by the Russian government in 2014 does not answer many questions and most importantly, it does not determine the current state of regions and efficiency of the state regional policy. Many provisions of the program are declarative in nature such as, for example, satisfaction of the population by quality of public and municipal services; the level of normative legal and methodological support of the powers of the Russian Federation subjects. It is not clear from the program on what and where the money will be spent, although the volume of federal budget allocations for the period 2013-2020 is 119,163,313.8 thous. rub. The main purpose of the study is to identify contradictions and tendencies of modern regional development, state regional policy, to analyze the impact of those policy on socio-economic and political development of the Russian society. To achieve this goal we have made the following hypothesis: does the modern state regional policy in Russia promote the objectives aimed at preserving an integrity and stability of the Russian state contributing to social well-being and development of a new quality of life of our citizens. The study includes the following methods and approaches in the capacity of the methodological basis for research: system and structure and functional approaches, sociological, logical and comparative methods and also analysis of the conditions and factors affecting the state regional policy of modern Russia. As a result of research, we came to the following conclusions: Regionalization issues in modern Russia took particular significance in connection with the collapse of the Soviet Union and the beginning of transformation of its totalitarian model with command-administrative management. The comprehensive and unprecedented for peacetime crisis which follows the collapse of the USSR has led to a loss of 40% of the national wealth and also gave rise to the desire of individual regions to search for ways out of the crisis separately. Under these conditions, the role of regional policy on the basis of which the emergence of a new Russia will be, increases immeasurably. The democratization of all aspects of life, a dramatic expansion in the early 90s of the rights of the Russian Federation subjects sharply actualized the problem on accommodation of interests of the state and the regions and demanded formulation of a state regional policy which objective should be both building a federal state and the socio-economic development of regions. Regional diversity makes it impossible for Russia to transfer an experience of any one country or the use of any one transition economy model tested in the world practice. In the process of its reforming, Russia must create a synthesis of domestic and international experience. The strength of Russia is in its regions, so the state regional policy in Russia is the basis, or the foundation which will allow our country to build a modern state and society

La2CuO4 as a Promising Oxygen Carrier for CLOU Process

The orthorhombic Ruddlesden-Popper phase La2CuO4±δ with the Cmce space group was obtained by a solid-state reaction route. Thermochemical data were calculated for the reaction of lanthanum cuprate formation Thermogravimetric measurements show the oxygen content is close to stoichiometric. Cyclic CLOU experiment was carried out to determine a specific oxygen capacity (ΔW0 exceeding 3.9%), as well as oxygen nonstoichiometry (δ) of La2CuO4±δ. The combustion rate of methane at 950 °C in the CLOU cycle about 0.5 1/min for one mole of lanthanum cuprate was achieved. © 2020 American Institute of Physics Inc..

Nakamura Tekisai and The New Book of Temperament （律呂新書）: A Philological Study of A Revision of the New Book of Temperament （修正律呂新書） and Notes for the New Book of Temperament（筆記律呂新書説）

The New Book of Temperament （律呂新書） was written by Tsai Yuan-ting （蔡元定）, a Neo-Confucianist in Southern Song Dynasty. Related to Neo-Confucianism, this book was widely spread across East Asian regions during the pre-modern age and has been extensively studied since then. After it was brought to Japan, Nakamura Tekisai, a Neo-Confucianist in early Edo Period, authored two monographs, A Revision of the New Book of Temperament（修正律呂新書） and Notes for the New Book of Temperament（筆記律呂新書説）. This thesis is an overview of the basic literature information about the two monographs that had remained unknown, through a philological study, aiming at revealing how Nakamura did some profound research into The New Book of Temperament and exploring the background to how he finally composed his monographs.東アジアの思想と構

Discrete surface solitons in semi-infinite binary waveguide arrays

We analyze discrete surface modes in semi-infinite binary waveguide arrays, which can support simultaneously two types of discrete solitons. We demonstrate that the analysis of linear surface states in such arrays provides important information about the existence of nonlinear surface modes and their properties. We find numerically the families of both discrete surface solitons and nonlinear Tamm (gap) states and study their stability properties.Comment: 3 pages, 4 figures, submitted to Opt. Let
