The article considers the problem of the relationship of structural changes and economic growth in the global economy and Russia in the framework of different methodological approaches. At the same time, the paper provides the analysis of complementarity of economic policy types, which, on the one hand, are aimed at developing the fundamentals of GDP growth (institutions, human capital and macroeconomic stabilization), and on the other hand, at initiating growth (with stable fundamentals) with the help of structural policy measures. In the study of structural changes in the global economy, new forms of policies of this kind have been revealed, in particular aimed at identifying sectors — drivers of economic growth based on a portfolio approach. In a given paper a preliminary version of the model of the Russian economy is provided, using a multisector version of the Thirlwall’s Law. Besides, the authors highlight a number of target parameters of indicators of competitiveness of the sectors of the Russian economy that allow us to expect its growth rate to accelerate above the exogenously given growth rate of the world economy.

Cup To Disc Ratio

Cup-to-disc ratio (CDR) is of great importance during assessing structural changes at the optic nerve head (ONH) and diagnosis of glaucoma. While most efforts have been put on acquiring the CDR number through CNN-based segmentation algorithms followed by the calculation of CDR, these methods usually only focus on the features in the convolution kernel, which is, after all, the operation of the local region, ignoring the contribution of rich global features (such as distant pixels) to the current features. In this paper, a new end-to-end channel and spatial attention regression deep learning network is proposed to deduces CDR number from the regression perspective and combine the self-attention mechanism with the regression network. Our network consists of four modules: the feature extraction module to extract deep features expressing the complicated pattern of optic disc (OD) and optic cup (OC), the attention module including the channel attention block (CAB) and the spatial attention block (SAB) to improve feature representation by aggregating long-range contextual information, the regression module to deduce CDR number directly, and the segmentation-auxiliary module to focus the model’s attention on the relevant features instead of the background region. Especially, the CAB selects relatively important feature maps in channel dimension, shifting the emphasis on the OD and OC region; meanwhile, the SAB learns the discriminative ability of feature representation at pixel level by capturing the relationship of intra-feature map. The experimental results of ORIGA dataset show that our method obtains absolute CDR error of 0.067 and the Pearson’s correlation coefficient of 0.694 in estimating CDR and our method has a great potential in predicting the CDR number.

Relationship Of

The relationship of the biochemical states to the mechanical events in contraction of smooth muscle cross–bridges is reviewed. These studies use direct measurements of the kinetics of P i and ADP release. The rate of release of P i from thiophosphorylated cycling cross–bridges held isometric was biphasic with turnovers of 1.8 s –1 and 0.3 s –1 , reflecting properties and forces directly acting on cross–bridges through mechanisms such as positive strain and inhibition by high–affinity MgADP binding. Fluorescent transients reporting release of an ADP analogue 3'–deac–edaADP were significantly faster in phasic than in tonic smooth muscles. Thiophosphorylation of myosin regulatory light chains (RLCs) increased and positive strain decreased the release rate around twofold. The rates of ADP release from rigor cross–bridges and the steady–state P i release from cycling isometric cross–bridges are similar, indicating that the ADP–release step or an isomerization preceding it may limit the ATPase rate. Thus ADP release in phasic and tonic smooth muscles is a regulated step with strain– and dephosphorylation–dependence. High affinity of cross–bridges for ADP and slow ADP release prolong the fraction of the duty cycle occupied by strongly bound AM·ADP state(s) and contribute to the high economy of force that is characteristic of smooth muscle. RLC thiophosphorylation led to structural changes in smooth muscle cross–bridges consistent with our findings that thiophosphorylation and strain modulate product release.

The Relationship

SYNOPSISCT scans were performed on 72 consecutive patients with a functional psychosis, and compared with 50 community controls. There was a specific difference in lateral ventricular area between these two groups but it accounted for only 11% of the variance in this measure. In contrast, racial and sexual differences in the ventricular-brain ratio (VBR) related to differences in intra-cranial area. It is argued that analysis of variance, using lateral ventricular area and intra-cranial area, is more informative than VBR in examining these structural changes in functional psychoses.

The relationship of changing demographic characteristics to health status and medical care in Latin America is examined in this article. The rapid demographic growth, high birth and death rates, although with a downward trend, the excessive expansion of the large cities, and the dispersion of the rural population are correlated with the unsatisfactory levels of health and living of the masses of the population, lack of medical care whose quality varies according to social class, and the limitations of the health systems. In the light of this analysis the authors discuss some of the tasks and prospects of the health sector. They contend that the situation described is basically due to inefficient social, economic, and political structures and an unhealthy dependence on external forces. Only radical structural changes will enable millions of Latin Americans to really have access to medical care, health, and life itself, an access which is their inalienable right and which today is denied them.

In the last decades, the confinement of various types of functional material in mesoporous silica matrices has been used to design hybrid organic-inorganic nanocomposites with unique and fascinating properties. Such nanocomposites have attracted considerable interest owing to their potential applications in various domains [1-2], while reports with precise structural information of such molecular nanomaterials are still rather scarce and quite disparate. However, in order to be able to derive a structure-functionality relationship of such hybrid complexes, a detailed description of the structural organisation of the guest species and of their immediate surrounding is absolutely mandatory. We show in this contribution that detailed structural information can be obtained by using an appropriate multiscale approach combining various experimental techniques such as X-ray total scattering coupled to atomic pair distribution function (PDF) and solid-state NMR spectroscopy. This multiscale approach does provide more extensive and accurate structural information [3]. The PDF approach has allowed the identification of the nature of the incorporated species and their arrangement as well as the distinction of the various existing phases: isolated molecules and nanoparticles. The multi-nuclei Solid State NMR investigation has provided information on both the amorphous host and the molecular guest and adds a dynamic dimension to the classical static structural characterisation. We also discuss the influence of the structural changes on the physical properties of the investigated materials

ABSTRACT Drosophila mojavensis and other species of the mulleri subgroup contain a duplicate gene encoding the enzyme alcohol dehydrogenase (ADH). Studies on the genetic relationship of the two genes using electrophoretic variants show them to be closely linked. We have cloned a 13.5-kb fragment of D. mojavensis DNA into the lambda vector, Charon 30. This fragment contains both Adh genes separated by approximately 2 kb of DNA. The clone hybridized to a single position on chromosome 3 in D. mojavensis following in situ hybridization. It is likely that the genes are tandemly arranged in the genome. One of the two genes shows a complexity in its structure that suggests the close linkage of a pseudogene or part of a gene.—The structure of the Adh locus in five species of the mulleri subgroup have been compared by constructing restriction maps of genomic DNA. Two of these species D. arizonensis and D. mojavensis express Adh-1 in the ovaries; the others do not. In comparing these species it is evident that there has been one or two insertions into the region between the Adh genes. It is possible that one of these structural changes is related to the change in Adh tissue-specific expression that has occurred during the evolution of these species.

The article is devoted to the analysis of the theoretical approaches of the theory of human capital and its definitions involving the coverage of concepts in historical retrospective. The relevance of the issue is due to a rather serious growth of the terminological field, which complicates the further theoretical conceptual development. Therefore, the aim of the article is to systematize existing approaches and basic concepts of human capital based on changes caused by interchangeable technological structures. The research methodology is based on the use of content analysis, historical and structural approaches. The research basis is classical studies of the theory of human capital as well as the work of Russian scientists over the past ten years. After the collection of scientific papers representing the conceptualization of theories of human capital was completed, selective work was analyzed (the selection was made by experts), which are of interest for systematizing and correlating the concepts of human capital with the theory of technological structures. Through content analysis, a multi-axis map of the «human capital» perception formed from the middle of the 20th century to the present moment was constructed. Such technological arguments were developed and described as «trends affecting the market and the nature of labor» and «education», as technological changes provoke sharp changes in the labor market and requirements for human capital. Moreover, the factors of its genesis and accumulation are changing. As a result, a systematization of human capital concepts was also proposed based on the criteria for interconnection with a change in technological patterns. This study can serve as the basis for further research on human capital in the context of technological and world economic structures. As an option to deepen this direction, we can offer an analysis of existing concepts of human capital based on the criteria for the relationship of its development with structural changes in the global economy.

The Relationship

The author uses the data of sociological researches conducted at the Institute of sociological research of the Russian Academy of Sciences for two dec-ades, one of the tasks of which was to study and analyze the attitude of individuals, groups and sec-tors of the population to the ongoing socio-structural changes in society. The research materials made it possible to analyze the features of the for-mation of new layers and groups in the modernizing Russian society and trace the change vector in their relationships. Secondary analysis of the obtained data allowed the author to identify several condi-tional periods of development of the Russian social system. The basis for highlighting these periods was the respondents' opinions on the criteria of social group membership in the modernizing Rus-sian society, on the relationship of new social groups, as well as the nature of the respondents' behavior strategies in the changed conditions of life. The author considers social and structural transfor-mations as a consequence of the general moderni-zation of the Russian social system.
