Lawsone encapsulated polylactic‐co‐glycolic acid nanoparticles modified with chitosan‐folic acid successfully inhibited cell growth and triggered apoptosis in Panc‐1 cancer cells
Authors: Ghafaripour Helia , Homayouni Tabrizi Masoud , Karimi Ehsan , Barati Naeeni Niloofar
Published: May 2023

The present research aims to encapsulate lawsone in polylactic‐co‐glycolic acid (PLGA) nanoparticles modified with folic acid (FA) and chitosan (CS) to study its anticancer effects against Panc‐1 cells. The nanoparticles were analysed in means of shape/size and zeta potential index using scanning electron microscope and dynamic light scattering. High‐performance liquid chromatography was applied to evaluate the lawsone entrapment efficacy. The authors performed acridine orange/propidium iodide staining and flow cytometry to monitor apoptosis induction and cell cycle arrest. The expressions of apoptosis‐related genes (BAX and BCL‐2) were assessed by real time PCR. Nanoparticle antioxidative and antibacterial activities were examined by DPPH/ABTS scavenging assay, disk diffusion method, and minimum inhibitory concentration and minimum bactericidal concentration evaluation. The NPs were 229.65 nm, the encapsulation efficiency was 81%. The concentration of lawsone that exerts 50% cell growth inhibition (IC50) against Panc‐1 cells was calculated 118.4 μL. Apoptosis induction was evidenced by the increased number of orange cells and increased proportion of cells in G1‐Sub phase respectively. Moreover, lawsone‐loaded nanoparticle upregulated BAX gene expression, while downregulated BCL2expression, suggesting the activation of apoptotic pathway. The observed cytotoxic/apoptotic properties suggest that Lawson‐loaded PLGA‐FA‐CS‐NPs hold a great potential in pancreatic cancer treatment.
Blind despreading and deconvolution of asynchronous multiuser direct sequence spread spectrum signals under multipath channels
Authors: Li Liangliang , Zhang Huaguo , Du Songmao , Liang Tao , Gao Lin
Published: May 2023

In non‐cooperative scenarios, the spreading sequences or waveforms of the direct sequence spread spectrum (DSSS) signals is unknown to the receiver. This paper focuses on addressing the problem of blind estimation of the spreading waveform under multipath channels. In the scenario of direct signal path transmission, the spreading sequences can be directly obtained based on the estimated spreading waveforms. However, in the presence of multipath channels, the spreading waveform becomes the convolution of the spreading sequence and channel response, thus deconvolution should also be performed after estimating the spreading waveforms. In order to perform blind despreading and deconvolution of asynchronous multiuser DSSS signals under multipath channels, the authors propose to exploit the finite symbol characteristics of information and spreading sequences and then the iterative least square with projection method is adopted. Besides, the Cramer‐Rao bound of spreading waveforms is derived in such a circumstance as a performance benchmark. The effectiveness of the proposed method is verified via simulation experiments.
Zeeman Doppler imaging ofξBoo A and B
Authors: Strassmeier K. G. , Carroll T. A. , Ilyin I. V.
Published: May 2023

Aims.We present a magnetic-field surface map for both stellar components of the young visual binaryξBoo AB (A: G8V, B: K5V).

Methods.We employed high-resolution Stokes-Vspectra obtained with the Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT). We inverted StokesVline profiles with ouriMAP software and compared them with previous inversions. We employed an iterative regularization scheme without the need for a penalty function and incorporated a three-component description of the surface magnetic-field vector. The spectral resolution of our data is 130 000 (0.040–0.055 Å) and we obtain a signal-to-noise ratio (S/N) of up to 3000 per pixel depending on wavelength. We used a singular-value decomposition (SVD) of a total of 1811 spectral lines to average Stokes-Vprofiles. Our mapping is accompanied by a residual bootstrap error analysis.

Results.We constructed magnetic flux densities of the radial field component forξBoo A andξBoo B of up to plus or −115±5 G and 55±3 G, respectively. The magnetic morphology ofξBoo A is characterized by a very high latitude, nearly polar spot of negative polarity and three low-to-mid-latitude spots of positive polarity, while that ofξBoo B is characterized by four low-to-mid-latitude spots of mixed polarity. No polar magnetic field is reconstructed for the coolerξBoo B star. Both our maps are dominated by the radial field component, containing 86% and 89% of the magnetic energy ofξBoo A and B, respectively. We find only weak azimuthal and meridional field densities on both stars (plus or −15–30 G), about a factor two weaker than what was seen previously forξBoo A. The phase averaged longitudinal field component and dispersion is +4.5±1.5 G for ξ Boo A and −5.0±3.0 G forξBoo B.
The effect of a small amount of hydrogen in the atmosphere of ultrahot magma-ocean planets: Atmospheric composition and escape
Authors: Charnoz Sébastien , Falco Aurélien , Tremblin Pascal , Sossi Paolo , Caracas Razvan , Lagage Pierre-Olivier
Published: May 2023

Context.Ultrahot (>1500 K) rocky exoplanets may be covered by a magma ocean, resulting in the formation of a vapor rich in rocky components (e.g., Mg, Si, Fe) with a low total pressure and high molecular mass. However, exoplanets may have also captured a significant amount of hydrogen from the nebular gas during their formation. Ultrahot rocky exoplanets around the Fulton gap (~1.8R⊕) are sufficiently large to have retained some fraction of their primordial hydrogen atmosphere.

Aims.Here, we investigate how small amounts of hydrogen (much smaller than the mass of the planet) above a magma ocean may modify the atmospheric chemistry and its tendency to thermally escape.

Methods.We use a chemical model of a magma ocean coupled to a gas equilibrium code (that includes hydrogen) to compute the atmospheric composition at thermodynamical equilibrium for various H contents and temperatures. An energy-limited model is used to compute atmospheric escape and is scaled to consider H-rich and H-poor atmospheres.

Results.The composition of the vapor above a magma ocean is drastically modified by hydrogen, even for very modest amounts of H (≪10−6planetary mass). Hydrogen consumes much of the O2(g), which, in turn, promotes the evaporation of metals and metal oxides (SiO, Mg, Na, K, Fe) from the magma ocean. Vast amounts of H2O are produced by the same process. At high hydrogen pressures, new hydrogenated species such as SiH4form in the atmosphere. In all cases, H, H2, and H2O are the dominant nonmetal-bearing volatile species. Sodium is the dominant atmospheric metal-bearing species atT <2000 K and low H content, whereas Fe is dominant at high H content and low temperature, while SiO predominates atT> 3000 K. We find that the atmospheric Mg/Fe, Mg/Si, and Na/Si ratios deviate from those in the underlying planet and from the stellar composition. As such, their determination may constrain the planet’s mantle composition and H content. As the presence of hydrogen promotes the evaporation of silicate mantles, it is conceivable that some high-density, irradiated exoplanets may have started life as hydrogen-bearing planets and that part of their silicate mantle evaporated (up to a few 10% of Si, O, and Fe) and was subsequently lost owing to the reducing role of H.

Conclusions.Even very small amounts of H can alter the atmospheric composition and promote the evaporation to space of heavy species derived from the molten silicate mantle of rocky planets. Through transit spectroscopy, the measurement of certain elemental ratios, along with the detection of atmospheric water or hydrogen, may help to determine the nature of a surface magma ocean.
Linear acceleration emission of pulsar relativistic streaming instability and interacting plasma bunches
Authors: Benáček Jan , Muñoz Patricio A. , Büchner Jörg , Jessner Axel
Published: May 2023

Context. Linear acceleration emission is one of the mechanisms that might explain intense coherent emissions of radio pulsars. This mechanism is not well understood, however, because the effects of collective plasma response and nonlinear plasma evolution on the resulting emission power must be taken into account. In addition, details of the radio emission properties of this mechanism are unknown, which limits the observational verification of the emission model.

Aims. By including collective and nonlinear plasma effects, we calculate radio emission power properties by the linear acceleration emission mechanism that occurs via the antenna principle for two instabilities in neutron star magnetospheres: (1) the relativistic streaming instability, and (2) interactions of plasma bunches.

Methods. We used 1D electrostatic relativistic particle-in-cell simulations to evolve the instabilities self-consistently. From the simulations, the power properties of coherent emission were obtained by novel postprocessing of electric currents.

Results. We found that the total radio power by plasma bunch interactions exceeds the power of the streaming instability by eight orders of magnitude. The wave power generated by a plasma bunch interaction can be as large as 2.6 × 1016 W. The number of bunch interactions that are required to explain the typical pulsar power, 1018 − 1022 W, depends on how the coherent emissions of bunches are added up together. Although ∼4 × (101 − 105) simultaneously emitting bunches are necessary for an incoherent addition of their radiation power, ≳6 − 600 bunches can explain the total pulsar power if they add up coherently. The radio spectrum of the plasma bunch is characterized by a flatter profile for low frequencies and by a power-law index up to ≈ − 1.6 ± 0.2 for high frequencies. The plasma bunches simultaneously radiate in a wide range of frequencies, fulfilling no specific relation between emission frequency and height in the magnetosphere. The power of the streaming instability is more narrowband than that of the interacting bunches, with a high-frequency cutoff. In both instabilities, the angular width of the radiation decreases with increasing frequency. In addition, the wave power evolution depends on the pulsar rotation angle, causing microsecond fluctuations in the intensity because it oscillates between positive and negative wave interference as a function of the emission angle.
Morphological and molecular characterisation ofTristoma integrumDiesing, 1850 (Monogenea, Capsalidae), including its complete mitogenome

Published: May 2023

Capsalids are monopisthocotylean monogenean parasites found on the skin and gills of fish. Capsalines (subfamily Capsalinae) are large-sized capsalids, parasitic on highly prized gamefish, and species ofTristomaparasitise only the gills of swordfish (Xiphias gladius). We obtained specimens ofTristoma integrumDiesing, 1850 from swordfish collected off Algeria in the Mediterranean Sea. Here, we describe the specimens, including the key systematics characters of dorsolateral body sclerites. One specimen was used for a next generation sequencing analysis but a part of it, including the sclerites, was mounted on a permanent slide, drawn, and deposited in a curated collection. We characterised the complete mitogenome, the ribosomal cluster (including 18S and 28S) and additional genes such as Elongation factor 1 alpha (EF1α) andHistone 3. We also retrieved molecular information from the host tissue present in the gut of the monogenean and provide the sequence of the complete rRNA cluster of the host,X. gladius. The mitogenome ofT. integrumis 13 968 bp in length and codes for 12 protein, 2 rRNA and 22 tRNA. Phylogenies of capsalids were generated from 28S sequences and concatenated mitochondrial protein-coding genes, respectively. In the 28S phylogeny, most subfamilies based on morphology were not found to be monophyletic, but the Capsalinae were monophyletic. In both phylogenies, the closest member toTristomaspp. was a member of theCapsaloides. In an Appendix, we report the complex nomenclatural history ofTristomaCuvier, 1817 and its species.
Aspects of preserving cultural diversity in modern conditions
Authors: Aliskhanova Malika Khamidovna , Gelagaeva Aruzha Magamedovna , Isipova Lalita Rukmanovna
Published: May 2023

The paper addresses the issues of preserving cultural diversity on the example of the Chechen Republic. Cultural values play an important role in the development of education, science, cultural life of peoples and cooperation, so each state strives to preserve these values for future generations. Representatives of more than 190 peoples live in the Russian Federation; hence, preservation of cultural diversity is one of the priorities of the state cultural policy. In modern conditions, the cultural diversity of civil nations is increasing, and the peoples are seeking more and more means, including political and legal ones, to preserve and develop their integrity and cultural image. One of the main factors that indicates the state of the ethnopolitical situation and the nature of interethnic relations is the balance of ethnic forces. Owing to stabilization of the socio-political situation in Chechnya, the need for revival of multi-ethnicity as the most important factor and condition for the republic development is a priority. Chechen society includes more than 40 peoples and nationalities. There are 11 national cultural centers and 6 national cultural autonomies in the Chechen Republic. Members of these organizations are actively involved in the public life of the region, promoting traditions and culture of their ethnic group. Modern nations are culturally, religiously and politically more pluralistic than traditional communities that have maintained their unity through fundamental traditions in culture or religion. The ethnocultural policy pursued in the Chechen Republic provides the conditions for representatives of ethnic communities to satisfy their national and cultural needs, and to preserve their religious and national identities.
Difficulties in fulfilling the first five-year plans in the industry of Chechnya in 1928–1937
Authors: Aliskhanova Malika Khamidovna , Isakieva Zulay Sulimovna , Barzaeva Petimat Ismailovna
Published: May 2023

The paper analyzes the difficulties of the Soviet-party leadership in the Chechen Autonomous Region in implementing the first five-year plans. The study of this problem is caused by the fact that modern Russia is experiencing a new round of modernization processes, and today the experience of previous generations is important so as not to repeat their mistakes. The subject of this study is of continuous interest among scientists who consider the present as a direct continuation of the past. Given the fact that the North Caucasus has a special place in the recent history of Russia in the last two decades, therefore, a deep study of the trends and contradictions of socio-economic development in Chechnya in the 1928–1937 allows identifying the historical origins and causes of modern problems in this region, which are a direct consequence of the accumulated contradictions in historical development. The policy of industrialization by the Soviet leadership was considered as a decisive factor in creating the material and technical base of socialism and ensuring the country’s defense potential. The industrial jump was caused primarily by the foreign policy aspect, so the leadership emphasized that to delay the pace means to lag behind. Industrialization for the Chechen Autonomous Region meant the creation of industrial production, because here it was almost absent, the main population was employed in agriculture. The city of Grozny with its factories was an independent region. In 1928, the Soviet leadership began to implement the directives of the first congress. The directives of the XV Party Congress emphasized the need for special attention to the issues of economic recovery and culture of backward national outskirts, which was the Chechen Autonomous Region by the beginning of the first five-year plans.
Personality and Society in the Dichotomy of Power and Freedom: Russian Contours
Authors: Bilalov Mustafa Isaevich , Babatova Aishat Sharipovna , Ramazanova Saida Rakipovna , Alilova Kalimat Mukhtarovna , Umarova Zara Yasuevna
Published: May 2023

The understanding the place of personality in history, its relationship with power and society as a whole is considered in the paper taking into account geography, social and economic characteristics, historical spiritual origins of the North Caucasian ethnic groups. A retrospective journey into history and philosophy allows comparing the options of the human community developed by peoples and civilizations – the relationship of the individual with power, with the values of freedom, knowledge, experience of capitalism, liberalism, socialism, to search for the most acceptable for Russia and its regions. Much attention is paid to European experience, which managed to accumulate the achievements of upbringing, education and science. In our opinion, the relations of personality and society in European civilization are refracted by a through line of power and knowledge, truth and freedom, perfectly revealed in the philosophical work of Nietzsche and Foucault. Their approach is very critical striking not so much with its objectivity but with pessimism and nihilism. Modern societies are disciplinary, and appropriate procedures as an interrelated sequence of actions of power and society, form such a person, having the ultimate goal of establishing dominance over it. This is not carried out in an obvious way, but by many layers of socio-political and cultural acts of the state. The paper gives preference to a regional civil society with Eurasian basic values that have the character of ideological-forming, resistant to the twists and turns of globalization. They form the spiritual structure of peoples and allow them preserving their identity, which is the goal and task of historical progress. Not the search for some main universal ways of development, but the desire of peoples to sufficiently large, but local civilizations, to communities in which optimal harmony of personality and state, citizen and power, freedom and responsibility is possible.

An essential component of the professional training of maritime cadets is their readiness to act skilfully in any accident or emergency situation. When a ship is destroyed, it is the responsibility of every crew member to know how to use the salvage equipment available on board and how to use it promptly and effectively. The subject of the study is the professional training of maritime cadets. The authors of the article substantiate and disclose the main points of the methodology for assessing the knowledge of lifeboat and raft equipment of maritime cadets. The methodology aims to serve in the convention training process as well as in the final certification of cadets in the Initial Security Training discipline. The article contains the results of the experimental work: testing cadets on the test-questionnaire of the considered method, their analysis and interpretation, as well as the mathematical processing of the results, proving the reliability and validity of this method. The authors agree that the use of the developed methodology in the practice of convention training in all maritime educational organisations would be appropriate and effective.
On the dualistic unity of natural science and the humanities
Authors: Safontseva Natalia
Published: May 2023

This paper is an analysis of the effectiveness of the Russian learners from the 2019 TIMSS International Monitoring Study report. While analyzing the document, the initial conclusion drawn by the author is that the mathematical and natural science literacy of Russian schoolchildren is quite high and that the educational system in Russia is stable. At the same time, the author suggests that rethinking the directions of educational development is impossible without taking into account the underlying processes occurring in the depths of basic general education. In the author's opinion, the lack of significant gains in the scores of Russian students over the last 2 phases of the TIMSS studies is an indicator of certain stagnation in primary mathematics and science education. The author is of the belief that a statement of this fact should contribute to the fundamentalism of education. Assessing the structural correlation between natural science and humanities knowledge by quantitative volume of academic load of mathematics and natural science disciplines, the author points to the dualistic unity of natural science and humanities knowledge in high school, which should contribute to the development of creative independent thinking of students. The author's understanding of the results of the context survey of Russian schoolchildren indicates the need to improve the professional expertise of the science teachers, which will improve the outcome of the educational process. The author suggests adopting the experience of other countries in implementing the interdisciplinary approach to the educational process. The author emphasizes that STEM education imposes special requirements on the teacher, who must have integrated knowledge of mathematics, science and technology, be fluent in computer programs, be motivated to work with children and be skilled in didactics.

A fuzzy model for assessing mathematical competences of university students
Authors: Pankina S.I. , Lyutikova M.N.
Published: May 2023

Within a competency-based approach to professional education, the paper outlines the concept of mathematical competence, grounds an urgency for effective mathematical competences and their assessment through a constructed fuzzy model. It promotes objective criteria for defining quantitative and qualitative indicators and assessing the level of all components. The topic addressed is novel in that it develops and implements a system for assessing the level of professional mathematical competences in tertiary education. The model constructed for evaluating the outcomes, based on the selected criteria, evaluates whether mathematical training opportunities are sufficient to satisfy the ultimate goal of training – the readiness of graduates for professional activities and on-fire specialties.
Interdisciplinarity in natural science and humanities as the basis for the development of education
Authors: Safontseva Natalia
Published: May 2023

The author analyzed the contradictory statements regarding the present and future of Russian education related to the choice of knowledge priorities between natural sciences and humanities. The author notes that pedagogical science should abandon the paradigm choice between the humanistic values of education and rationalistic technological approaches to the learning process. The author believes that the changes in humanities knowledge should be considered as a consequence of changes in the natural science knowledge. This fact testifies to the mutual penetration of various ways of thinking and the dualistic unity of seeming opposites. By interpreting the technocracism as a concept of the power of professionals based on scientific and technical knowledge, the author suggests that the development of education should be based on dualistic unity, and not on the contrast between natural science and humanitarian knowledge. The author notes that at the current stage of the development of civilization the priority task is to prepare transprofessionals with integral interdisciplinary professional competencies that are able to solve professional tasks at the intersection of various sciences, while understanding the social consequences of their actions. According to the author, technocratism ensures the transition from ideas about the desired image of a graduate of an educational institution to a truly developed professionally competent person with fundamental education. At the same time, humanistic values determined by the culture and national traditions of their country should provide high ethical and moral personal qualities of a transprofessional, without which sufficient civic responsibility and an active life position in conditions of continuous technogenic transformations in all spheres of life are impossible.
Historical aspects of the formation of the Russian mentality
Authors: Bogatyreva V.V.
Published: May 2023

This paper examines the legal mentality as an element of the structure of legal consciousness, as well as its characteristic expressions. It also pays attention to the historical factors that influenced the formation of the Russian mentality, due to the adoption of Christianity in Russia. A comparative analysis of the impact of this concept in different periods of formation and development of the Russian state is conducted. Russian law has rather deep roots going back to the history of ancient Russian society. Since the content of law is reflected in legal ideas, in this regard, it is advisable to study Russian law from a deep and comprehensive study of the legal mentality of Russian society.

Published: May 2023

The article studies the problems of quality and efficiency of public administration. The article describes foundations of a new concept of public administration – the concept of expert quality control of the government policy (EQGP), which is an effective way to improve the quality and efficiency of government in post-industrial (information) society. In order to improve the efficiency of government administration, it is necessary to improve the mechanisms for forming public bodies and to implement monitoring mechanisms into the system of public bodies formation. To achieve this goal, it is necessary to activate expert communities (“expert factories”), to enhance expert and analytical activities both at the stage of formation of public bodies (examination of election programs) and monitoring of their activities (examination of reports). Depending on the positions occupied by experts in the decision-making system, four models of expert control have been identified. The features of each model are presented. The article also describes the basic principles of EQGP.

The study reveals ways to identify and describe the psycholinguistic meanings of lexical units (on the example of the toponym "Vladikavkaz"). Psycholinguistic meaning is one of the types of meanings along with the traditional type of meaning such as lexicographic meaning. The lexicographic meaning consists of a small set of logically meaningful features that reflect described phenomenon. The lexicographic meaning is presented in classical explanatory dictionaries. It is formulated on the basis of the principle of reductionism (minimization of features included in the meaning). The psycholinguistic meaning is the meaning in the minds of native speakers. This type of meaning is presented in psycholinguistic dictionaries. The psycholinguistic meaning can be identified by various methods. An effective method for identifying and describing psycholinguistic meanings is a psycholinguistic experiment, in particular, an associative experiment that involves native speakers. Associative experiments were carried out by the Russian Voronezh theoretical and linguistic school in the Russian Federation. The subjects were native Russian speakers in the North Caucasus and Voronezh. Toponyms of the Russian language were used as stimulus materials – "Derbent", "Dagestan", "Moscow", "St. Petersburg", etc. The experiments identified a lot of associative reactions, the distribution of which made it possible to construct associative fields. The semantic interpretation of associative fields revealed the psycholinguistic meanings of toponyms. This article presents the results of semantic interpretation of associative reactions to the stimulus "Vladikavkaz", obtained in the experiments. The associative fields of the toponym are described. The semantic components of the toponym are identified. The psycholinguistic meaning of the toponym "Vladikavkaz" is formulated in two regional variants.
