Institutional-synergetic approach in benchmarking of territorial industrial policy
The authors argue that an industrial policy for a territory is a crucial means for its development and suggest theoretical and methodological outline for its benchmarking. The fact of creating priority development areas (PDAs), which are similar to special economic zones, whose inefficiency is now recognized, confirms the suspicion that PDA creation is an outcome of political lobbing rather than economic planning. Governmental efforts on the federal, regional and municipal levels lack consistency. The current economic conditions lead to fierce competition for investment, which makes municipal and regional governments more open to investors, on the one hand, but on the other, may lead to some poor decision-making. The authors argue that in view of the current priorities of technological innovation, coordination of diverse stakeholders’ interests and goals in PDA dynamics, it is imperative to integrate a PDA development strategy into the industrial policy of a territory. Conceptually, this research relies on the institutional-synergetic approach to benchmarking of territorial industrial policies. This approach can help us develop an industrial policy for a specific PDA by building upon this area’s competitive advantages and by evaluating the available alternatives. To improve managerial decision-making, it is also recommended to study and adopt Russian and international experience in this sphere. PDAs should act as self-organizing systems in order to engage institutions and mechanisms of development 'in the right place at the right time' and employ tools of synergetic management ('stimulate trigger points') for positive synergetic effects.The research was funded by the Russian Foundation for Humanities, project 'Strategy of Formation and Management of Priority Development Areas Based on the Implementation of the Territorial Industrial Policy' № 16-02-00073
Hostility, Anger, Psycho-emotional Factors and Cardiovascular Disease
The review presents the main aspects of the relationship between psychoemotional factors, hostility, anger and cardiovascular diseases. The first chapter describes the main historical stages in the study of this problem, starting from the Middle Ages and ending with fundamental research of the 19-20 centuries. In the second part, the authors demonstrated that hostility/anger are a risk factor for the CVD development and affect the prognosis and course of CVD (hypertension, ischemic heart disease, various cardiac arrhythmias, etc.). In the third chapter, there were studies that found that high rates of hostility/ anger reduced the effectiveness of cardiovascular therapy. In the fourth part, there are the main correlation mechanisms of negative emotions, hostility/anger and the cardiovascular system, carried out through the relationships with the activation of the hypothalamic-pituitary-adrenal, autonomic nervous system, platelet activation, with the changes in the risk factors characteristics etc. In the final chapter, the authors suggested prospects for further study of the problem, probably associated with the assessment of behavioral interventions, pharmacological or complex effects on the severity of hostility/anger to reduce CVD mortality in individuals with high rates of hostility / anger
Topology of "white" stars in relativistic fragmentation of light nuclei
In the present paper, experimental observations of the multifragmentation
processes of light relativistic nuclei carried out by means of emulsions are
reviewed. Events of the type of "white" stars in which the dissociation of
relativistic nuclei is not accompanied by the production of mesons and the
target-nucleus fragments are considered.
A distinctive feature of the charge topology in the dissociation of the Ne,
Mg, Si, and S nuclei is an almost total suppression of the binary splitting of
nuclei to fragments with charges higher than 2. The growth of the nuclear
fragmentation degree is revealed in an increase in the multiplicity of singly
and doubly charged fragments with decreasing charge of the non-excited part of
the fragmenting nucleus.
The processes of dissociation of stable Li, Be, B, C, N, and O isotopes to
charged fragments were used to study special features of the formation of
systems consisting of the lightest , d, and t nuclei. Clustering in
form of the He nucleus can be detected in "white" stars via the
dissociation of neutron-deficient Be, B, C, and N isotopes.Comment: 20 pages, 3 figures, 9 tables, conference: Conference on Physics of

Fragmentation of relativistic nuclei in peripheral interactions in nuclear track emulsion
The technique of nuclear track emulsions is used to explore the fragmentation
of light relativistic nuclei down to the most peripheral interactions - nuclear
"white" stars. A complete pattern of therelativistic dissociation of a B
nucleus with target fragment accompaniment is presented. Relativistic
dissociation Be is explored using significant statistics and
a relative contribution of Be decays from 0 and 2 states is
established. Target fragment accompaniments are shown for relativistic
fragmentation N3He+H and Ne5He. The leading role of the
electromagnetic dissociation on heavy nuclei with respect to break-ups on
target protons is demonstrated in all these cases. It is possible to conclude
that the peripheral dissociation of relativistic nuclei in nuclear track
emulsion is a unique tool to study many-body systems composed of lightest
nuclei and nucleons in the energy scale relevant for nuclear astrophysics.Comment: 15 pages, 4 figures, 4 tables, conference: Relativistic nuclear

Distributed Computing Grid Experiences in CMS
The CMS experiment is currently developing a computing system capable of serving, processing and archiving the large number of events that will be generated when the CMS detector starts taking data. During 2004 CMS undertook a large scale data challenge to demonstrate the ability of the CMS computing system to cope with a sustained data-taking rate equivalent to 25% of startup rate. Its goals were: to run CMS event reconstruction at CERN for a sustained period at 25 Hz input rate; to distribute the data to several regional centers; and enable data access at those centers for analysis. Grid middleware was utilized to help complete all aspects of the challenge. To continue to provide scalable access from anywhere in the world to the data, CMS is developing a layer of software that uses Grid tools to gain access to data and resources, and that aims to provide physicists with a user friendly interface for submitting their analysis jobs. This paper describes the data challenge experience with Grid infrastructure and the current development of the CMS analysis system
Institutional factor in international economic activity of region and its socio-economic development
The article substantiates the impact of the institutional factor on the development of regional international economic relations. The scope of the study is regional international economic activity (IEA), the subject-matter is the role of the institutional factor in its development. The study purpose is to develop a scientific approach for the assessment of the institutional factor impact on the development of region's international economic relations. The hypothesis is that the targeted efforts of all participants of IEA of the region (business, authorities, local community) to strengthen of theese components of the institutional factor, which have a strong influence on the regional socio-economic development. A methodological approach for the assessment of this influenceis developed. It includes determining three elements of IEA institutionalization - agreements, organizations, events. A three-dimensional model is proposed for the coordination of these elements with 3 groups of countries - developed, developing and CIS, including the Eurasian Economic Union, and also with basic indexes characterizing the qualitative and quantitative contribution of region's IEA into its socio-economic development. This model is tested on the example of the Sverdlovsk region of Russia for 2003-2015. That has allowed to define various kinds of the effects from strenthening the IEA institutional component, which are expressed in the increase of the export of the region, improvement of its investment attractiveness, the diversification of regional economy as well as the the generation of additional jobs and tax flows increase. © Copyright 2005-2016 Institute of Economics, the Ural branch of the RAS.

Effect of gliprolines on lipid peroxidation rate in male rats’ immunocompetent organs under conditions of information stress
Introduction. The study of various aspects of the stress-reactivity of the body’s immune system, along with the search for correction tools characterized by immunoregulatory properties, is one of the most relevant areas of physiology and pharmacology. Currently, neuropeptides belonging to the group of glурrоlins (the registered drug “sеlаnk” and the new compounds Рro-Glу-Рro-Leu and Рro-Glу-Рro) are of particular interest in practical application as promising bioregulators, in particular their effects on the processes of free radical oxidation, as well as the ability to restore changes from the immune system, including those formed in response to stress.The aim of the study: was to study the effect of glурrоlins on the intensity of lipid peroxidation, catalase activity in the spleen and thymus of male rats under experimental information stress.Material and methods. The study was performed on white nonlinear male rats on which the model of information stress, based on the formation of behavior in animals in a multi-alternative food-producing maze, was reproduced for 20 days. The initial content of malondialdehyde, the rate of spontaneous and ascorbate-dependent lipid peroxidation were determined by standard spectrophotometric methods, and the activity of catalase in the homogenate of the thymus and spleen of experimental animals was evaluated.Results. Under the studied stress conditions, an increase in peroxidation processes was noted. Against the background of the introduction of sеlаnk, Рro-Glу-Рro and Рro-Glу-Рro-Leu, the suppression of the intensity of lipid peroxidation processes in the homogenates of the spleen and thymus tissue of male rats was established (a decrease in the initial level, the rate of spontaneous and ascorbate-dependent lipid peroxidation).Conclusions. Injection of neuropeptides belonging to the group of glyprolins (sеlаnk, Рro-Glу-Рro-Leu and Рro-Glу-Рro) under informational stress conditions contributes to the suppression of the intensity of lipid peroxidation processes, which indicates the stress-protective and immunocorrective effect of the studied substances
Relationship of the White Coat Effect with Endpoints and Several Prognostic Indicators in Hypertensive Patients Treated with Regular Antihypertensive Therapy
Aim of the study was to evaluate in a prospective cohort study the relationship between the severity of the white coat effect (WHE) in patients with hypertension, who treated with regular antihypertensive therapy, and the composite endpoint, several prognostic indicators, in a routine clinical practice.Material and Methods. We analyzed the data of a prospective cohort study, which included 125 patients with hypertension who received regular antihypertensive therapy. The study consisted of three visits (baseline, 6 and 12 months) and an outcome data collection period (30.1±7.6 months of follow-up after the third visit). This study included three visits every 3 months: 1 visit – screening, ambulatory blood pressure monitoring (ABPM) session, Echo; 2 – assessment of the patient’s status and the therapy effectiveness; 3- assessment of the patient’s status, ABPM session, Echo (the total number of ABPM was 239, Echo - 240). The primary composite endpoint included death for any reason angina pectoris, transient ischemic attack, development of chronic heart failure, arterial revascularization, frequent ventricular extrasystoles, atrial fibrillation, secondary - deterioration of the cardiovascular diseases course and tertiary endpoint – deterioration of the arterial hypertension, concomitant diseases course.Results. The study involved 125 patients: 28 men (22%), 97 women (78%), mean age was 62.6±0.8 years, duration of hypertension 11.6±0.8 years, height 163.6±0.7 cm, body weight 83.1±1.4 kg. The baseline mean daytime systolic BP (SBP) was 125.1±9.8 and diastolic (DBP) – 76.1±7.0 mm Hg, age was 62.8±9.0 years, the WCE level for SBP was 16.5±1.4, for DBP 10.9±0.7 mm Hg. We identified a positive correlation between tertiary composite endpoint data and WCE: for systolic WCE (SWCE) (F = 4.7, p<0.031). We found correlations between WCE and Echo parameters: 1) SWCE level had with LVMI (r = 0.16. p<0.017); 2) diastolic WCE (DWCE) had negative relationship with LV contractility parameters.Conclusions. Thus, only systolic WCE level had correlation with composite endpoint data and LVMI. DWCE level had negative associations with echocardiography LV contractility parameters
Changes of photosynthesis and carbon metabolism in Typha angustifolia L grown in conditions of nitrate nitrogen overload
Nitrates may induce alterations in NO-signaling system and change photosynthesisin plants. Significant reduction of 14CO2 fixation was noted at concentration of 3.96mM NaNO3 in an aquatic macrophyte (Typha angustifolia L.). Assimilation of 14CO2 seven days after the introduction of nitrates did not differ between control and experimental samples. There were changes in distribution of 14C among products of 4CO2 fixation 4 h after NaNO3 addition, resulting in increased sugar radioactivity in experimental plants. It was suggested that the observed changes may have regulatory importance
Mechanism of completion of peptidyltransferase centre assembly in eukaryotes.
During their final maturation in the cytoplasm, pre-60S ribosomal particles are converted to translation-competent large ribosomal subunits. Here, we present the mechanism of peptidyltransferase centre (PTC) completion that explains how integration of the last ribosomal proteins is coupled to release of the nuclear export adaptor Nmd3. Single-particle cryo-EM reveals that eL40 recruitment stabilises helix 89 to form the uL16 binding site. The loading of uL16 unhooks helix 38 from Nmd3 to adopt its mature conformation. In turn, partial retraction of the L1 stalk is coupled to a conformational switch in Nmd3 that allows the uL16 P-site loop to fully accommodate into the PTC where it competes with Nmd3 for an overlapping binding site (base A2971). Our data reveal how the central functional site of the ribosome is sculpted and suggest how the formation of translation-competent 60S subunits is disrupted in leukaemia-associated ribosomopathies.Bloodwise, MRC, Wellcome Trus
