Diversification of transit risks of Russia as a basis for economic and energy security in European countries

The paper examines the dependence of energy security against the European Union (EU) and Russia, where the main threats are the insufficient diversification of supplies, the difficulties in gas transportation and the high transit tariffs. It covers the threats of location of the gas transportation system in Ukraine, through the territory of which a significant volume of gas purchases to the EU countries is delivered. The ways of diversifying transit risks have been identified through the Yamal-Europe, Blue Stream, and Nord Stream gas pipelines, as well as by the implementation of the Nord Stream 2 gas pipeline. This will allow diversifying the EU transit risks and supplying gas to Austria through the territory of Germany, the Czech Republic and Slovakia. In turn could be determined by political and economic instability. In the methodological part of the paper, an analysis of gas consumption in the countries of Central and Eastern Europe was made, which showed fairly stable consumption with a slight decrease in demand.peer-reviewe

Software selection based on analysis and forecasting methods, practised in 1C

The research focuses on the problem of a "1C: Enterprise 8" platform inboard mechanisms for data analysis and forecasting. It is important to evaluate and select proper software to develop effective strategies for customer relationship management in terms of sales, as well as implementation and further maintenance of software. Research data allows creating new forecast models to schedule further software distribution

Photoionization of Xe 3d electrons in molecule Xe@C60: interplay of intra-doublet and confinement resonances

We demonstrate rather interesting manifestations of co-existence of resonance features in characteristics of the photoionization of 3d-electrons in Xe@C60. It is shown that the reflection of photoelectrons produced by the 3d Xe photoionization affects greatly partial photoionization cross-sections of and levels and respective angular anisotropy parameters, both dipole and non-dipole adding to all of them additional maximums and minimums. The calculations are performed treating the 3/2 and 5/2 electrons as electrons of different kinds with their spins "up" and "down". The effect of C60 shell is accounted for in the frame of the "orange" skin potential model.Comment: 13 pages, 12 figure

Non-dipole angular anisotropy parameters of semi-filled shell atoms

We present the results of calculations of outer shell non-dipole angular anisotropy parameters for semi-filled shell atoms in the Hartree-Fock (HF) one-electron approximation and with account of inter-electron correlations in the frame of the Spin Polarized Random Phase Approximation with Exchange (SP RPAE). We demonstrate for the first time that this characteristic of photoionization process is essentially sensitive to the fact whether the photoelectron has the same or opposite spin orientation to that of the semi-filled shell.Comment: 15 pages, 8 figure

Teaching Academic English to Russian-speaking Academic Staff: The Case of the Office of Academic Writing

The paper discusses the preliminary results of teaching academic writing to scientific and academic staff at South Ural State University (national research university) within the framework of advanced training courses. The 36 and 72-hour training programs were developed by the academic and methodological department of the Office of Academic Writing. The Office was opened at the university in 2016 in order to improve the academic literacy of the university’s academic staff, develop professional communication skills in English, and assist authors who aspire to get their papers published in top rated scientific journals indexed in the scientific citation databases Scopus and Web of Science. Upon completion of these programs, authors of scientific papers gain knowledge about the basics of academic writing, the structure of a scientific paper, the English scientific style and its lexical and grammatical features, as well as editing a paper, working with scientific citation databases, and elaborating a publishing strategy. We conducted a study from October 2016 to December 2018 and calculated data on the attendees’ affiliation (an institute or higher school), the contingent (position), and the importance of the offered training programs (the number of attendees in each course). The obtained data indicates that representatives of social-humanitarian and technical fields show a special interest in the courses. The courses of academic writing are most popular among associate professors who have experience in publishing papers in Russian. Authors are especially interested in intensive practice-oriented programs. Upon completion of the courses and with the support of the Office of Academic Writing, attendees prepared scientific texts in English and submitted them to top rated journals and conference proceedings. The educational activity of the Office of Academic Writing can be developed through elaboration and implementation of new advanced training programs, including the distance ones. Their effectiveness will be evaluated by an increase in the publication activity of the university’s employees

Bichromatic dressing of a quantum dot detected by a remote second quantum dot

We demonstrate an information transfer mechanism between two dissimilar remote InAs/GaAs quantum dots weakly coupled to a common photonic crystal microcavity. Bichromatic excitation in the s state of one of the dots leads to the formation of dressed states due to the coherent coupling to the laser field, in resonance with the quantum dot. Information on the resulting dressed structure is read out through the photoluminescence spectrum of the other quantum dot, as well as the cavity mode. The effect is also observed upon exchange of the excitation and detection quantum dots. This quantum dot intertalk is interpreted in terms of a cavity-mediated coupling involving acoustic phonons. A master equation for a three-level system coherently pumped by the two lasers quantitatively describes the behavior of our system. Our result presents an important step towards scalable solid-state quantum networking based on coupled multi-quantum-dot-cavity systems, without the need to use identical quantum emittersThis work was supported by the Spanish MINECO under Contract No. MAT2011-22997, by CAM under Contract No. S2009/ESP-1503, and by the FP7 ITN Spin-optronics (237252).
