A.A. Gromyko and Security Policy: Helsinki compromise (to the 115th anniversary of A.A. Gromyko)
No full textThe article continues the study of the role of the Minister of Foreign Affairs of the USSR A.A. Gromyko in the formation, development and maintenance of security policy, its principles and structural elements. The subject of the article is the research of the preparation, content and prospects of the development of the Helsinki Compromise. On August 1, 1975, this compromise was enshrined in the final act of the Conference on Security and Cooperation in Europe. The article consists of four sections. The first section is dedicated to the problem of the connections between the Western interpretation of progress and the possible influence on the Western world. This problem will be scientifically examined in further articles. In the second section, the author proves that the main task of A.A. Gromyko in 1975 was to agree on the compromise as quickly as possible and then to begin with the main directions of cooperation between states. In the third section, the author analyzes the content of the compromise. In addition, the most important peculiarity (no existence of a common and specific project for all countries) is highlighted. In the fourth section, the author characterizes A.A. Gromyko's ideas about the prospects of the development of the Helsinki compromise. What is new is the interpretation of the CSCE decisions in 1975, the interpretation of the meaning and contradictions in the Gromyko system. The sources of the article are published documents of the Foreign Office of the Federal Republic of Germany, the use of which can be explained methodologically. It was important for the author to conduct the analysis on the basis of the foreign partners' assessment of the statements made by the Soviet Foreign Minister during official negotiations (outer reflection). The author's reasoning should be understood in the context of his earlier article in the journal
A.A. BRUSILOV - FULL GENERAL OF RUSSIAN ARMY AND LAST COMMANDER OF RUSSIAN TSAR
No full textThe article analyzes the biography of Russian full general A.A. Brusilov − the hero of World War I, whose name is associated with the term “Brusilov Offensive”. The author exa-mines his views on the new situation which developed in Russia during the two revolutions of 1917, and then in the Soviet period. The author highly appreciates the theoretical preparation level of A.A. Brusilov, who got full military education in tsarist Russia; reveals the pre-sence of numerous analogous episodes in the biographies of A.A. Brusilov and A.V. Suvorov. He focuses on the similar origin of two Russian heroes, whose families belonged to the military dynasties of imperial Russia. The author concludes that the continuity of generations is very important in the issue of effective army’s functioning. This tradition was preserved in the new Soviet state

Licensee MDPI, Basel, Switzerland.Organic light emitting transistors (OLETs) combine, in the same device, the function of an electrical switch with the capability of generating light under appropriate bias conditions. In this work, we demonstrate how engineering the dielectric layer based on high-k polyvinylidene fluoride (PVDF)-based polymers can lead to a drastic reduction of device driving voltages and the improvement of its optoelectronic properties. We first investigated the morphology and the dielectric response of these polymer dielectrics in terms of polymer (P(VDF-TrFE) and P(VDF-TrFE-CFE)) and solvent content (cyclopentanone, methylethylketone). Implementing these high-k PVDF-based dielectrics enabled low-bias ambipolar organic light emitting transistors, with reduced threshold voltages (<20 V) and enhanced light output (compared to conventional polymer reference), along with an overall improvement of the device efficiency. Further, we preliminary transferred these fluorinated high-k dielectric films onto a plastic substrate to enable flexible light emitting transistors. These findings hold potential for broader exploitation of the OLET platform, where the device can now be driven by commercially available electronics, thus enabling flexible low-bias organic electronic devices.Peer reviewe
Continuous representation for shell models of turbulence
No full textIn this work we construct and analyze continuous hydrodynamic models in one space dimension, which are induced by shell models of turbulence. After Fourier transformation, such continuous models split into an infinite number of uncoupled subsystems, which are all identical to the same shell model. The two shell models, which allow such a construction, are considered: the dyadic (Desnyansky--Novikov) model with the intershell ratio and the Sabra model of turbulence with . The continuous models allow understanding various properties of shell model solutions and provide their interpretation in physical space. We show that the asymptotic solutions of the dyadic model with Kolmogorov scaling correspond to the shocks (discontinuities) for the induced continuous solutions in physical space, and the finite-time blowup together with its viscous regularization follow the scenario similar to the Burgers equation. For the Sabra model, we provide the physical space representation for blowup solutions and intermittent turbulent dynamics
A.A. Gromyko and Security Policy: Conflict of Strategies after Helsinki
No full textThe article continues the study of the role of the Minister of Foreign Affairs of the USSR A.A. Gromyko in the formation, development and maintenance of security policy, its principles and structural elements. The subject of the article is the analysis and comparison of the strategies of A.A. Gromyko and the Western countries in 1976–1977 after the signing of the Helsinki Final Act. The article consists of three parts. In the first part, the author analyzes the strategic course of A.A. Gromyko and proves that the Soviet Foreign Minister understood détente as a three-level process. For this reason, he wanted to agree on the common content of détente and to build cooperation between states of different status in the system of international relations that would be beneficial for all participants. The second part describes the West’s strategic course. The author shows that the West hoped to weaken the USSR, lure the country into a foreign policy game, «keep the Soviets in good spirits» and obtain voluntary concessions from the country. The Helsinki Final Act was as a «provisional high point» that would lead to a fight for what had been achieved. In the third part, the positions of A.A. Gromyko and the Western political elite were compared. For the first time in historiography, the thesis about a real possibility of dialogue between the USSR and the United States on the legal formalization of the status of the great powers was presented. The author recommends taking into account the proposals of A.A. Gromyko in the modern system of international relations. The sources of the article are published documents of the Foreign Office of the Federal Republic of Germany, the use of which can be explained methodologically. It was important for the author to conduct the analysis on the basis of the foreign partners' assessment of the statements made by the Soviet Foreign Minister during official negotiations (outer reflection).

Hamiltonian formalism for weak turbulence of inertial waves in rotating fluids
No full textWe present the Hamiltonian description of incompressible rotating fluid by using the Clebsch variables. We find the transformation which allows us to present the three-wave interaction Hamiltonian in normal variables in simple explicit form. We analyze the three-wave interaction amplitude and find new anisotropic spectra. Finally we study the convergence of integrals and present the kinetic equation
