Fragmentation and Multifragmentation of 10.6A GeV Gold Nuclei

We present the results of a study performed on the interactions of 10.6A GeV gold nuclei in nuclear emulsions. In a minimum bias sample of 1311 interac- tions, 5260 helium nuclei and 2622 heavy fragments were observed as Au projec- tile fragments. The experimental data are analyzed with particular emphasis of target separation interactions in emulsions and study of criticalexponents. Multiplicity distributions of the fast-moving projectile fragments are inves- tigated. Charged fragment moments, conditional moments as well as two and three -body asymmetries of the fast moving projectile particles are determined in terms of the total charge remaining bound in the multiply charged projectile fragments. Some differences in the average yields of helium nuclei and heavier fragments are observed, which may be attributed to a target effect. However, two and three-body asymmetries and conditional moments indicate that the breakup mechanism of the projectile seems to be independent of target mass. We looked for evidence of critical point observable in finite nuclei by study the resulting charged fragments distributions. We have obtained the values for the critical exponents gamma, beta and tau and compare our results with those at lower energy experiment (1.0A GeV data). The values suggest that a phase transition like behavior, is observed.Comment: latex, revtex, 28 pages, 12 figures, 3tables, submitted to Europysics Journal

Создание нормативно-правовых и институциональных условий развития образовательной миграции в России

The publication aims to analyze the existing regulatory framework in the field of edu- cational migration for the implementation of strategic documents in the field of foreign and humani- tarian policy of Russia; assess how the existing legal mechanisms for educational migration meet the objectives; to formulate the institutional conditions for a new stage in the export of Russian education, taking into account geopolitical changes. The publication also presents the results of the monitoring of “double degree” programs conducted by RUDN University in 2022, as well as the risks of introducing a new system of higher education in Russia in the aspect of internationalization. The methodological basis of the study is the analysis of statistical data in the field of international education, as well as the analysis of the regulatory framework, which includes the legislation of the Russian Federation; departmental regulatory documents, international experience. Main research methods: analysis, formal legal and comparative legal.Публикация ставит своей целью провести анализ существующей нормативно-правовой базы в области образовательной миграции по реализации стратегических документов в области внешней и гуманитарной политики России; оценить, насколько существующие правовые механизмы образовательной миграции отвечают поставленным задачам; сформулировать институциональные условия нового этапа экспорта российского образования с учётом геополитических изменений. Также в публикации представлены итоги мониторинга программ «двойных дипломов», проведённого РУДН в 2022 г., а также риски внедрения новой системы высшего образования в России в аспекте интернационализации. Методологическую базу исследования представляют анализ статистических данных в области международного образования, а также анализ нормативно-правовой базы, которая включает законодательство Российской Федерации, ведомственные нормативно-правовые документы, международный опыт. Основные методы исследования: анализ, формально-юридический и сравнительно-правовой
