EAEU — Cuba: Institutionalization of Interaction and the Potential of Modern Cooperation

The research is aimed at studying the process of establishment and development of Eurasian-Cuban partnership under new geopolitical conditions and its role in the emerging global economy and geopolitics. The author reviews the methodical work of Eurasian Economic Commission as well as the system-forming role of Russia in building a mutually beneficial partnership with the Republic of Cuba, the priorities of interaction and the factors of influence are defined.Aim. To appraise significance and potential of the Cuban direction in the Eurasian Economic Union strategy in the context of the emerging multipolarity.Tasks. To study the process of institutionalization of the Eurasian-Cuban partnership, main areas of cooperation, current trends and factors of influence, determining the prospects for interaction.Methods. A combination of general scientific theoretical and special methods is used. The method of comparative analysis and the logical method are of prime importance. When working with regulatory and legislative sources, the normative method is used.Results. The potential of EAEU — Cuba relations has not been implemented yet; there are clear disproportions between the member countries; and the growing role of Chinese factor in the context of Eurasian-Cuban relations requires due consideration.Conclusion. Effective coordination within EAEU — Cuba — China can provide joint implementation of global challenges targeted at states’ sustainable development under the formation of a multipolar world order

Search for Pairs of Isolated Radio Pulsars - Components in Disrupted Binary Systems

We have developed a method for analyzing the kinematic association of isolated relativistic objects - possible remnants of disrupted close binary systems. We investigate pairs of fairly young radio pulsars with known proper motions and estimated distances (dispersion measures) that are spaced no more than 2-3 kpc apart. Using a specified radial velocity distribution for these objects, we have constructed 100-300 thousand trajectories of their possible motion in the Galactic gravitational field on a time scale of several million years. The probabilities of their close encounters at epochs consistent with the age of the younger pulsar in the pair are analyzed. When these probabilities exceed considerably their reference values obtained by assuming a purely random encounter between the pulsars under consideration, we conclude that the objects may have been gravitationally bound in the past. As a result, we have detected six pulsar pairs (J0543+2329/J0528+2200, J1453-6413/J1430-6623, J2354+6155/J2321+6024, J1915+1009/J1909+1102, J1832-0827/J1836-1008, and J1917+1353/J1926+1648) that are companions in disrupted binary systems with a high probability. Estimates of their kinematic ages and velocities at binary disruption and at the present epoch are provided

HE ROLE OF TURKEY IN EASTERN MEDITERRANEAN BY AMERICAN RESEARCHERS

The article analyzes the main approaches developed by American analysts in research centers - the “think tanks” and universities of the United States, concerning the role of Turkey in the eastern Mediterranean in the context of the events taking place in the region at the moment. Despite the fact that there is no consensus on the future role of Turkey as an ally of the United States and NATO in the region among American experts, the need for the direct involvement of the White House in the resolution of regional conflicts is not in doubt and is determined by strategic interests of the USA in the Eastern Mediterranean and the Middle East

Views of Ukrainian Crises in Research of American Think-tanks

The paper is a brief analysis of the main approaches developed within American “think-tanks” concerning the events taking place in Ukraine. According to most researchers, the Ukrainian crisis requires US strong engagement to confirm the key geopolitical role of the White House as the sole guarantor of the stability of the current Euro-Atlantic and the Middle Eastern security environment

EXPLANATION: Exoplanet and Transient Event Investigation Project—Optical Facilities and Solutions

Peer reviewed: TrueOver the past decades, the achievements in astronomical instrumentation have given rise to a number of novel advanced studies related to the analysis of large arrays of observational data. One of the most famous of these studies is a study of transient events in the near and far space and a search for exoplanets. The main requirements for such kinds of projects are a simultaneous coverage of the largest possible field of view with the highest possible detection limits and temporal resolution. In this study, we present a similar project aimed at creating an extensive, continuously updated survey of transient events and exoplanets. To date, the core of the project incorporates several 0.07–2.5 m optical telescopes and the 6-m BTA telescope of the Special Astrophysical Observatory of RAS (Russia), a number of other Russian observatories and the Bonhyunsan observatory of the Korea Astronomy and Space Science Institute (South Korea). Our attention is mainly focused on the description of two groups of small, wide-angle optical telescopes for primary detection. All the telescopes are originally designed for the goals of the project and may be of interest to the scientific community. A description is also given for a new, high-precision optical spectrograph for the Doppler studies of transient and exoplanet events detected within the project. We present here the philosophy, expectations and first results obtained during the first year of running the project.</jats:p
