According to the Federal Project «Russia is an attractive country for studying and working», by 2030 the number of foreign students should increase by 1.5 times compared to 2021. In recent years, higher education educational institutions of higher education have made significant progress in attracting foreign students on average, their annual growth in the number of foreign students in Russian universities in during the last previous three years has beenbeing about 6 % per year. The attraction ofAttracting foreign students in recent years has been associated with serious challenges: the pandemic and quarantine restrictions (2020–2021), the forced transition of universities to distance learning (2020– 2022), the transformation of the geopolitical situation, the allocation of the category of unfriendly countries, the rejection of the Bologna format of the organization of the educational process organization. These factors have also left their mark oninfluenced the admission campaign of the 2022–2023 academic year. The authors of the articlethis paper aim to at identifying the key problems of internationalization of education internationalization in modern conditions. We propose fundamentally new managerial and legal solutions for the development of educational migration developmentat a qualitatively new level. The empirical basis of the study was a university international services employees’ survey of employees of international services ofpoll universities and the official statistics of international and Russian organizations. The main research methods are formal legal and comparative legal. The article may be useful tomight be of use for the employees of educational authorities, uni versity management, employees and of university international services of educational institutions of higher education, for university managers, and for international education experts in the field of international education.

Objective: to study the socio-cultural and legal nature of the corruption phenomenon in a discursive and communicative context.Methods: the methodological basis of the article is the synthesis of the discursive and communicative theory of J. Habermas and W. Krawietz’s integrative theory of legal reality, focusing on the interdisciplinary study of corruption as an interdisciplinary category, taking into account not only objective, but also subjective components. This determined the choice of research methods (comparative, hermeneutic, and discursive methods).Results: corruption as a phenomenon and the interdisciplinary category reflecting it is determined by social, cultural and psychological factors of the legal reality development. Acting as a complex legal archetype, it defines the value attitudes of consciousness and behavior of the legal communication participants, orienting them to carry out actions aimed at satisfying individual (less often group and social) interests, even if they contradict the law. Corrupt behavior is perceived by a large part of the Russian society as a model of hierarchical interaction of the legal communication subjects, the purpose of which, according to the addressee, is to increase the effectiveness of the addressee’s activities. In addition, corruption is becoming an informal means of “liberation” from the legal requirements, rigid and unfair, according to some representatives of the society. In these conditions, the success of the institutional fight against corruption can be achieved only if this fight involves not only improvement of anti-corruption legislation, but also countering shadow norms, creating a system of anti-incentives for corrupt behavior, including ideologically, through the formation of value attitudes of citizens to reject corrupt practices as unpatriotic and harmful to the rule of law and the legal culture of the society as a whole.Scientific novelty: for the first time in Russian jurisprudence, a study of the category of corruption in the communicative and discursive aspect was conducted.Practical significance: the main provisions and conclusions of the article can be used in scientific and pedagogical activities when considering the issues of the essence and content of the Russian legal reality, in the anti-corruption activities of state and municipal bodies, as well as in anti-corruption education.

PurposeThe goal of research consists in identifying trends in academic mobility in Russia and abroad, primarily that of academic staff; contributing suggestions on improving the management of academic mobility processes.Design/methodology/approachThe research uses methods of observation, comparative analysis, as well as statistical method and generalization method supported by the facts. A comparative analysis of statistical data is made; these data were taken from the publicly available reliable sources of the Organization for Economic Cooperation and Development, Human Resource Development Department of the Asia–Pacific and others.FindingsIt was found that the level of academic mobility rises with the rising level of education. The overall mobility of tertiary students – in particular, students and postgraduate students, is growing throughout the world. Mobile postgraduate students demonstrate better research results during training. Even short-term academic internships for postgraduate students contribute to the successful implementation of research projects at their host university and the spread of new knowledge in general. In general, academic mobility contributes to the accumulation of human and cultural scientific capital that makes a connection between research communities in different countries. Based on the research findings, it was found that no statistics are collected on the foreign academic mobility of postgraduate students and young researchers in Russia. Based on the analysis, it may be deduced that the scope of academic mobility is extremely small. European countries are the main countries of prevailing academic mobility.Originality/valueGiven the importance of participation in foreign academic mobility for the development of the competitiveness of national science in Russia, it appears that there is a need to monitor the foreign academic mobility of Russian postgraduate students and young researchers. The monitoring of foreign academic mobility of Russian postgraduate students and young researchers is a systematic observation of the status and conditions of training highly qualified personnel in Russian educational establishments and scientific organizations, providing educational authorities of Russia with up-to-date information on the status of outgoing academic mobility necessary for analyzing and forecasting the development of the national education system and national labor market.

Targeted transport systems for drug delivery to the central nervous system (CNS) are reviewed. A modern classification of dosage forms according to generation and characteristic features is presented. The main targeted delivery systems for CNS drugs based on nanocarriers such as liposomes, polymer nanoparticles, polymer micelles, solid lipid nanoparticles, and nanoparticles of chitosan and human serum albumin are examined.

To monitor the heart muscle state and assess the risks of heart disease, the researchers need a lot of information. Recording functional indicators of autonomic heart rate control can provide a significant amount of valuable data. These indicators include, for example, the amount of respiratory arrhythmia or the relationship between baroreflex and heart rate. It is believed that a decrease in the influence of these factors on the heart rate indicates a reduction in the" internal reserves" of the body and can predict the upcoming development of heart diseases. In this study, we propose an algorithm for processing the baroreflex function to assess the cardiovascular system's health.

To study the reactions of the cardiovascular system during continuous monitoring in the dynamics of their development and analysis of the main hemodynamic parameters during the movement and orientation of the subjects (postural loads), a vector-based method was developed for assessing changes in systemic hemodynamics parameters: stroke index and mean arterial pressure. The vector representation allows us to get an idea of the intensity of changes in the patient’s hemodynamic status, expressed through the length of the vector. Based on the proposed method, a classification of hemodynamic reactions was developed.

Taisiya I. Skorobogatova, Olga Yu. Suraleva (Southern Federal University, Rostov-on-Don, Russian Federation) Research of national specificity of phraseology in a national language by distinguishing thematic groups of phraseological units and the analysis of their component composition becomes increasingly important in linguistic studies. This article is devoted to the analysis of the French phraseological units, which include dendronyms. Authors narrow notion of “dendronym” and use it only to refer to the names of trees. In French phraseological corpus authors identified 18 dendronyms, which are core components of the floral phrasal units: amandier (almond tree), cedre (cedar), chene (oak), cocotier (coconut palm), cypres (cypress), figuier (fig tree), laurier (laurel tree), murier (mulberry), olivier (olive tree), orme (elm), osier (willow), palmier (palm), peuplier (poplar), platane (sycamore), poirier (pear), pommier (apple), prunier (plum), sapin (spruce, fir). The following list proves that the repertoire of dendronyms used to form French FU is not too wide. However, the authors confirmed the possibility to consider idioms-dendronym component as special items of historical and cultural memory. Key words: floral phraseology, phraseological unit, dendrons, historical/ cultural memory, the French language .

The relevance of this article is conditioned by the need to analyze and study the student views and positions on the issue of intercultural communication and intercultural interaction, as it is obvious that in the foreseeable future we will continue to live in a multi-ethnic, multicultural society and strive for the successful coexistence of many different cultures in social networks. The aim of the study is to identify the attitude of students communicating in social networks to ethnocentrism. The leading methods for the study of this problem are the methods of questioning and testing, allowing making a qualitative analysis of the peculiarities of the attitude of students communicating in social networks, to ethnocentrism, and allowing identifying the position of students on the issue of intercultural communication and intercultural interaction. The article reveals the criteria peculiar to the representatives of different ethnic groups with a high level of ethnocentrism. These students consider everything that happens in their culture to be natural and correct, and in others to be wrong; consider the customs of their group as universal: “what is good for us is good for others”; consider the norms, roles and values of their group to be absolutely correct; act so that the representatives of their group feel like winners; feel hostility towards external groups. It is determined that the presence of a set of these criteria and properties (or most of them) in the ethnic consciousness of the individual, allows us to talk about a high level of ethnocentrism. The novelty and originality of the study lies in the fact that a set of criteria characterizing the opinion of students, supporters of cultural relativism is revealed: they are often in contact with representatives of other ethnic groups and nationalities in social networks; absolutely do not feel discomfort in communicating with foreign cultural representatives, on the contrary, such communication is of great interest; in the formation of any group do not give preference to representatives of their own people, and are guided by other selection criteria; do not regard the culture of their people as a role model for other Nations. A set of criteria is identified for supporters of ethnocentrism: they believe everything that happens in their culture, natural and correct and others wrong; consider the customs of their group as universal; consider the norms, roles and values of their group is certainly correct; feel hostility towards external groups; in General, are rarely in contact with the representatives of other ethnic groups and nationalities; feel discomfort in communicating with other cultures representatives; believe that the loss of identity of their ethnic group is an unambiguously negative phenomenon; they do not consider the cultures of all peoples equally important and equal.

The method of analyzing the stability of self-oscillations in relay systems allows us to investigate their stability in the case of an analytical description of the oscillations. Relay systems are widely used in various fields of technology because of the ease of implementation and speed control. In contrast to the known methods of analytic description of self-oscillations, the new method developed by the authors allows to investigate complex cases that have not previously been analyzed, for example, an integrator or aperiodic link in the linear part of the system, and also removes restrictions on the continuity of the impulse response of the system. Another advantage of the method is the relative ease of implementation. A comparative evaluation of the results of the analytical calculation of self-oscillations and stability analysis for symmetric self-oscillations with repetitions after half a period and asymmetrical with repetitions through a period is carried out.

In recent years, interest in non-drug methods of treating cardiovascular diseases, including the use of postural effects for rehabilitation purposes, has significantly increased. Hemodynamic reactions during postural effects are associated with a significant redistribution of blood and can be used to achieve certain positive hemodynamic reactions, and the problem of controlling the main hemodynamic parameters arises. To solve this problem, the complex of diagnostic indicators was expanded, in addition to those already included in clinical practice, such as arterial stiffness and central arterial pressure evaluation (they are important for identifying people with high cardiovascular risk). To achieve this goal, the developed system includes additional measuring channels, algorithms for processing the received signals, implemented methods for assessing the patient’s condition using an extended set of indicators.

The algorithm of processing and analysis of surface ECG signal and intracardiac electrograms is considered. The algorithm provides real-time detection of premature ectopic beats, episodes of atrial fibrillation and flutter, life-threatening ventricular heart rhythm disturbances. The detection of heart rhythm disturbances’ localization is performed based on the character of excitation wave propagation along conductive heart pathways and myocardium. The localization of heart rhythm disturbances is detected by processing of synchronous recordings of intracardiac electrograms and surface ECG.

This paper presents an analysis of the common problems in identifying the key points of pulse wave. For the processing of synchronous recorded pulse wave and electrocardiogram signals a software module has been developed in MATLAB program. This module provides displaying of the signals, key points detection, pulse wave transit time calculation and evaluation of the variability of this parameter. For estimation of the characteristic form of the pulse wave an averaged model of several neighbor cardiac cycles depending on reference point is developed. The model allows visually evaluating the shape of the pulse wave and determining the average parameters values for the selected segment. To assess the variability of pulse wave shape overlapping could be implemented.

The article describes the telemedicine system for home monitoring of blood pressure, which allows patients with arterial hypertension to provide remote diagnosis of their current health status. Due to the analysis of existing methods of blood pressure monitoring, the necessity of realization of the system for blood pressure measurement based on the modified oscillometric method was substantiated, the structural diagram of device intended for autonomous recording of human pressure signals by oscillometric method was developed. Proposed algorithm for determination of blood pressure values uses the maximum amplitude algorithm and an algorithm based on the neural networks. The presented algorithms are implemented in the MAILAB software. The results of their approbation on the signals obtained from the developed device have shown the efficiency of the algorithm using neural network technology, especially when processing distorted pressure signals, which allows increasing the accuracy of blood pressure measurement in people with disabilities of cardio-vascular system.

The full destruction (FD, that implies the disintegration into singly and doubly charged fragments only) characteristics are presented for some light nuclei ( 6 12 C, 8 16 O, 10 22 Ne, and 14 28 Si) with an energy of 3.7A GeV and heavy projectiles 79 197 Au (10.7A GeV) and 82 208 Pb (158A GeV) interacting with target nuclei in a photoemulsion. It is shown that (i) the average number of fragments, the realization of various fragmentation channels, and the degree of crushing for light projectiles substantially depend on the charge of a residual nucleus and on the mass of a target nucleus; (ii) the FD probability for residual nuclei with the same charge, as well as the multiplicity of fragments for the same impact parameter of heavy nuclei, are independent of the energy; and (iii) the integral distribution of transverse momenta of doubly charged fragments is described by two exponents (the logarithmic plot exhibits a break).

The production of $$\overline {D^0 } $$ -mesons on hydrogen and nuclear targets (carbon and aluminium) by (38–70) GeV neutrons has been analysed. The decay mode $$\overline {D^0 } \to K^ + \pi ^ - \pi ^ + \pi ^ - $$ has been studied. The longitudinalp L and transversep T momenta have been reconstructed and described by the forms (1−X F )N withN=2.3 −0.3 +0.2 and exp(-Bp T 2 ) withB=(1.3 −0.3 +0.2 ) (GeV/c)−2, respectively. In the sensitive kinematic region of (30≤p l ≤60) GeV/c $$(X_F \tilde > 0.5)$$ andp T ≤1GeV/c the cross sections are: σH2=(3.1±1.1)μb,σ c = (27.5±9.3) μb/C nucleus andσ Al =(49.6±16.3)μb/Al nucleus. The dependence of the $$\overline {D^0 } $$ -production cross section on the atomic weightA was parametrized by the power law form $$\sigma _A = K\sigma _{H_2 } A^\alpha $$ withK=1.5±0.8 andα=0.73±0.23.

In this paper we present the results of a search for the charmed strange baryon Ξc+ in the final states Λ0π+π+K− and Ξ−π+π+. The experiment was performed using the magnetic spectrometer BIS-2 with a hydrogen target located in the neutron beam of the Serpukhov accelerator. A narrow peak in the Λ0π+π+K− state is observed at a mass of ≈2440 and possibly also of ≈2310 MeV/c2, corresponding to signals for the Ξc+ → Λ0π+π+K− and Ξc+ → Σ0π+π+K− (Σ0 → Λ0γ) decays respectively. The statistics obtained for the Ξ−π+π+ state is too low to make any conclusion.

We present results of the exclusive diffractive reaction np → Λ0K0p at 0·08 < |t|< 0·53 GeV2/c2 and momenta between 30–70 GeV/c at the Serpukhov neutron beam. Thet-dependence is exp (Bt) withB= 11·4± 2·3 (GeV/c)−2 and it exhibits the diffractive minimum at ¦t¦ 0·28 GeV2/c2 for Λ0K0 massesM < 1·8 GeV/c2.B decreases with increasingM. Correlation with the beam direction is observed in the rest frame of the Λ0K0 system: the cross section rises for the forward-going Λ0. The rise is more pronounced for higherM. The cross section of reaction np → Λ0K0p for 0

A search for baryonia with negative and positive strangeness decaying respectively into\(\Lambda + \bar p + pions\) and\(\bar \Lambda + p + pions\) has been carried out in a neutron beam with a mean momentum of ≅40 GeV/c in an experiment performed at the Serpukhov accelerator. There is a strong indication of the existence of these baryonia. The following four charge states are observed for negative and positive strangeness: neutral, negative, positive and doubly charged. Their mean mass is 3055±25 MeV/c2 and the width Γ≦36±15 MeV/c2. The data show that the isotopic spin of the baryonia is ≧3/2. The baryonia production cross sections in the acceptable kinematic regionXF≧0.2 andPT≦1 GeV/c times the branching ratios of the observed decays are of the order of 1 μb per nucleon.

The reaction of terminal α-acetylenic ketones with o-aminothiophenol results in the formation of 3-acylvinyl-2-acylmethylbenzothiazolines.

TheA-dependence of the polarization ofΛ 0, s produced inclusively in neutron-nucleus interactions at a mean neutron momentum of about 40 GeV/c has been measured in an experiment performed using the BIS-2 spectrometer at the Serpukhov accelerator. Carbon, Aluminium and Copper targets were used. TheΛ 0, s were produced in the kinematical region of 0.6

In this paper we study the inclusive production of the charmed baryon Λ c + in interactions of 40–70 GeV/c neutrons with protons of hydrogen target. The experiment has been performed with the use of magnetic spectrometer BIS-2 located in the neutron beam of Serpukhov accelerator. The signal of Λ c + is observed in the effective mass spectra of Λ°π+π+π−. After the removal of interactions occurring on the container of liquid hydrogen, the signal consists of 14 combinations corresponding to ≈4 standard deviations of background. Its mean value is 2262 MeV/c2, width of the bin containing signal is 20 MeV/c2. On the basis of this signal we determine the value of cross section of Λ c + production times the branching ratio of its observed decay modeσ. Br (Λ c + → Λ°π+π+π−)=0·26±0·11 μb in the kinematic region ofx F>0·5 andp T

4,5,6,7-Tetrahydroindole and its 1-vinyl derivative were obtained in overall yields of 30–60% by the reaction of cyclohexanone oxime with 1,2-dichloro- and 1,2-dibromoethane in the MOH-dimethyl sulfoxide (DMSO) superbase system (M = K, Na, Li). Nucleophilic substitution of the halogen in the dihaloethanes by the oximate anion to give the corresponding ethylene glycol bis (imido ether) is a side reaction. The effect of the reaction conditions on the yields of products and the selectivity of the process was examined.

The addition of bromine to vinyl derivatives of 2-hydroxypyridine, 2-hydroxylepidine, and 8-hydroxyquinoline was studied. The behavior of the compounds differs as a function of the structure and the position of the vinyl group attached to the oxygen or nitrogen of the pyridine ring. A complex involving the unshared electron pair of the nitrogen atom is obtained with 2-vinyloxypyridine and bromine. N-Vinyl-2-pyridone and 2-vinyloxylepidine add bromine primarily at the double bond of the vinyl group. This reaction proceeds in a more complex fashion with N-vinyl-2-lepidone and 8-vinyloxyquinoline. The structures of the synthesized compounds were investigated by means of IR and PMR spectra.
