Authors: Pirzada S. , Haq Mohd Abrar Ul
Published: August 2023

Let G be a connected graph with n vertices, m edges. The distance signless Laplacian matrix DQ(G) is defined as DQ(G) = Diag(Tr(G)) + D(G), where Diag(Tr(G)) is the diagonal matrix of vertex transmissions and D(G) is the distance matrix of G. The distance signless Laplacian eigenvalues of G are the eigenvalues of DQ(G) and are denoted by δ1
Q(G), δ2
Q(G), ..., δn
Q(G). δ1
Q is called the distance signless Laplacian spectral radius of DQ(G). In this paper, we obtain upper and lower bounds for SDQ
(G) in terms of the Wiener index, the transmission degree and the order of the graph.

Authors: Ramane Harishchandra S. , Parvathalu B. , Ashoka K. , Patil Daneshwari
Published: August 2023

The energy E(G) of a graph G is the sum of the absolute values of eigenvalues of G and the Seidel energy ES(G) is the sum of the absolute values of eigenvalues of the Seidel matrix S of G. In this paper, some relations between the energy and Seidel energy of a graph in terms of different graph parameters are presented. Also, the inertia relations between the graph eigenvalue and Seidel eigenvalue of a graph are given. The results in this paper generalize some of the existing results.
Explainable patch-level histopathology tissue type detection with bag-of-local-features models and data augmentation
Authors: Galiger Gergő , Bodó Zalán
Published: August 2023

Automatic detection of tissue types on whole-slide images (WSI) is an important task in computational histopathology that can be solved with convolutional neural networks (CNN) with high accuracy. However, the black-box nature of CNNs rightfully raises concerns about using them for this task. In this paper, we reformulate the task of tissue type detection to multiple binary classification problems to simplify the justification of model decisions. We propose an adapted Bag-of-local-Features interpretable CNN for solving this problem, which we train on eight newly introduced binary tissue classification datasets. The performance of the model is evaluated simultaneously with its decision-making process using logit heatmaps. Our model achieves better performance than its non-interpretable counterparts, while also being able to provide human-readable justification for decisions. Furthermore, the problem of data scarcity in computational histopathology is accounted for by using data augmentation techniques to improve both the performance and even the validity of model decisions.

Authors: Palatka József , Kovács Levente , Szilágyi László
Published: August 2023

Interstitial Lung Diseases (ILDs) represent a heterogeneous group of several rare diseases that are di cult to predict, diagnose and monitor. There are no predictive biomarkers for ILDs, clinical signs are similar to the ones for other lung diseases, the radiological features are not easy to recognize, and require manual radiologist review. Data-driven support for ILD prediction, diagnosis and disease-course monitoring are great unmet need. Numerous image processing techniques and computer-aided diagnostic and decision-making support methods have been developed over the recent years. The current review focuses on such solutions, discussing advancements on the fields of Quantitative CT, Complex Networks, and Convolutional Neural Networks.
On connectivity of the semi-splitting block graph of a graph
Authors: Baskar Nivedha , Mangam Tabitha Agnes , Acharya Mukti
Published: August 2023

A graph G is said to be a semi-splitting block graph if there exists a graph H such that SB(H) ≌ G. This paper establishes a characterisation of semi-splitting block graphs based on the partition of the vertex set of G. The vertex (edge) connectivity and p-connectedness (p-edge connectedness) of SB(G) are examined. For all integers a, b with 1 < a < b, the existence of the graph G for which κ (G) = a, κ (SB(G)) = b and λ (G) = a, λ (SB(G)) = b are proved independently. The characterization of graphs with κ(SB(G)) = κ (G) and a necessary condition for graphs with κ (SB(G)) = λ (SB(G)) are achieved.
Intensive Counseling of Smokers for Nicotine Addiction Cessation and Health Benefits of Smoking Cessation
Authors: Ancuţa Constantin , Bivolaru Sorin , Mihălţan Florin
Published: August 2023

Smoking is a chronic disease with a recurring character, one of the oldest habits on the globe but also a problem of modern society, which kills more than 8 million people each year. More than 50% of those deaths are the result of direct tobacco use, while around 1.2 million are the result of non-smokers being exposed to second-hand smoke(1). Nicotine addiction must be seen as a chronic disease, with numerous periods of relapse and remission, and is mandatory that the clinician must treat it properly.

Smoking cessation is of critical importance to public health, various studies indicate that smoking is a major risk factor for a variety of serious health conditions, including cancer, heart disease, stroke, and chronic obstructive pulmonary disease (COPD). The risk of developing these conditions is directly related to the amount and the duration of smoking and is higher for those who start smoking at a younger age. While counseling is likely to be successful in helping individuals quit smoking, there are also other methods to reach the goal, including medication, nicotine replacement therapy, and lifestyle changes. However, these methods may not be as effective as counseling in helping individuals quit smoking. Otherwise, other methods, such as reducing the amount of smoking or switching to a less harmful form of tobacco, may reduce the risk of developing some of the conditions associated with smoking, but they do not reduce the risk to the same level as quitting smoking.
Bochdalek Hernia in an 83-Year-Old Ex-Pulmonology Nurse
Authors: Bogdan George , Cotea Antonio , Mihălţan Florin Dumitru , Constantin Ancuţa Alina
Published: August 2023

Bochdalek hernia (BH) represents the herniation of abdominal visceral components through a discontinuity between the lateral (costal) and posterior (crural) components of the diaphragm. With an incidence directly proportional to age, it is rare in adults, with reported frequencies in the specialized literature ranging from 0.17% to 6% of all diaphragmatic hernias, and it is the most common type of congenital diaphragmatic hernia, affecting the left hemidiaphragm in 85% of cases(1,2).

The authors describe the case of an 83-year-old patient, a former nurse in a pneumology department, diagnosed with Bochdalek hernia, which mimicked a suspicious neoplastic lung mass. The patient's clinical context and conducted investigations established the benign etiology of the formation, without requiring further surgical intervention. Additionally, we provide a brief review of the medical literature on this topic, radiological approaches, and the importance of differential diagnosis.
Understanding the Effects of Politicizing Media Operations: A Study of the Patriotic Front Regime (2011–2021)
Authors: Tiwine Zimba Muchipa  , Sanny Mulubale
Published: August 2023

There are various forms of Media that have a wider reach of communication, such as newspapers, radio, television, internet-based websites, and magazines. These have a major impact on politics, especially television, radio and newspapers. However, media reporting has received a reaction from political leaders and, in some cases, banned for what is deemed negative reporting against the ruling government. This paper explores the relationship between media and politics in the context of democratic tenets. The study used both secondary and primary sources of data collection. A total of 25 participants took part in this study as key informants. These were selected through purposive sampling and several official and academic documents were reviewed to address this study's aim. The collected data were analysed through a thematic, methodological approach. The findings show that the influence that the Patriotic Front (PF)'s time in government was defined by both successes and a shrinking media space for political debates and information sharing with the public. It was found by this study that television stations, such as Prime TV, with highly politicised content being aired, were bridled by the government to the point of their closure. This study has revealed that various political party structures of the Patriotic Front were used to intimidate the media. Based on the findings, it can be argued here that media houses' critical role in politics was not consolidated but rather constrained during the period under study.

Published: August 2023

This study intended to document the contribution of IGAs to the financial performance of the public secondary schools in Nyamira County. The introduction of Free Secondary Education brought massive financial calamities, and most schools are operating negatively in relation to cost. The objectives were to examine the type of IGAs engaged in public secondary schools in Nyamira County and to ascertain the factors influencing the performance of income-generating Activities in public secondary schools in Nyamira County. This research used Resource Dependence Theory. The study embraced a descriptive research design. Target population was 5 County education officers, 147 principals, 1076 teachers, and 37,070 students in Nyamira County. The researcher purposefully sampled 5 County Education Officers. Simple random sampling was embraced to get 15 Principals, 108 teachers, and finally 240 students. A total of 368 respondents took part in this investigation. Interview schedules and research questionnaires were used to gather data. Piloting of the instrument was done. The data were gathered through editing, coding, tabulating, and then analyzed, and SPSS 23 was applied. Quantitative data were displayed by descriptive statistics like tables.

Numerous factors, such as the size of the project, school liquidity, inadequate finances, politics, supervision, operating costs, management capacity, and level of development in learning institutions, influenced income-generating activities in schools. The study recommends that a policy framework on income-generating activities to engage in should be formulated, regular training to equip teachers with skills to manage income-generating activities, proper record keeping should be embraced to ensure there is accountability in learning institutions, the ministry of education should encourage schools to partner with different agencies and sponsors to finance in this county and beyond.
Oil Diplomacy in the International Economy: Impact of Russia–Ukraine Conflict
Authors: Osaseri Frances Eseosa  , Dr. Agbebaku Philip Enahoro  , Agba, Emeka Augustine
Published: August 2023

Russia's invasion of Ukraine has demonstrated how vulnerable energy markets are. Russia's invasion has made a tenacious situation much worse for energy markets, particularly in Europe. For now, the biggest question facing world leaders is how to sever their energy dependence on Russia. The United States and the United Kingdom were the first major countries to ban Russian oil, but neither depended heavily on these imports. Moreover, the impact of such actions is minimal because Russia can simply redirect that oil elsewhere on the global market. An embargo would only work if the EU took part, economists say, because it would be difficult for Russia to quickly find new customers for the oil and gas it sends to Europe. The late stages of the Industrial Revolution, which occurred in the early 20th century, saw oil rise to prominence as a commodity. As a result of the increasing importance of petroleum in modern warfare, petroleum politics have become a crucial factor in international relations. As a result, oil plays a crucial role in geopolitics, as countries compete to secure oil supply through trade, diplomacy, armed conquest, and other means. The changing situation of economic and political dominance in the world is now evident in the crisis. How much influence does Russia command in Europe and outside with its oil and other energy commodities? This study aims to review the relevance of oil in international politics and the various ways the current conflict between Russia and Ukraine is changing the narratives of oil diplomacy in the international economy. This study uses mercantilism, one of the four theories of international economic relations, to explain the situation that has witnessed the stability of Russia's economy despite strong waves of sanctions tossing it about. Evidence from reviewed literature shows that it is the global economy that carries the weight of the current crisis. It is, therefore, vital for policymakers worldwide to seek alternative means of survival if Russia decides to react by restricting its export of strategic global commodities of which it is a significant export leader, like oil.
The Convergence Criteria of Monetary Integration and Economic Performance of Sub-Saharan African Countries
Authors: Orji, Alexander C  , Osang, Paul A  , Okeke, Tabansi C
Published: August 2023

Based on the experience of countries that have adopted the use of a single currency, there is no doubt that monetary integration remains a key strategy for Sub-Saharan African (SSA) countries to transform themselves into a strong united bloc of developed nations and a global force. Therefore, this study examines the impact of the convergence criteria of monetary integration on the economic performance of SSA countries from 1999 to 2021, using Panel Autoregressive Distributed Lag Model (PARDL). About nine SSA countries from the four regions of SSA were randomly selected, and the countries include: Nigeria, South Africa, Angola, Kenya, Lesotho, Ghana, Ethiopia, Democratic Republic of Congo, and Central African Republic. In order to achieve the main objective of this study, the annual panel data were collected from World Bank database on the variables such as Gross Domestic Product growth rate (GDPG), Inflation Rates (INFR), Real Exchange Rates (REXR), and Fiscal Deficit (FDEF). The panel unit root and Johansen Fisher cointegration tests were conducted on all the variables. While the variables exert mixed order of integration, there exists a long-run relationship among the variables. The PARDL results reveal that the inflation rate has an insignificant positive effect on the GDP growth rate in the long run and an insignificant negative effect in the short run. The result further shows that in both the long and short run, the real exchange rate has an insignificant negative impact on the economic performance of SSA countries. The fiscal deficit result shows a significant positive impact on the GDP growth rate in SSA countries both in the long run and short run. The study, therefore, recommends that government should formulate a policy that would strengthen local currencies against foreign currencies, probably by fixing the exchange rates. If this is done, the inflation rate will be tamed through various productions of goods and services at reduced costs.

This study aims to determine the effect of pregnant women’s fear of COVID-19 on their expectations, experiences, and reactions in the first ultrasound examination. This study was conducted with 166 pregnant women who visited the polyclinic in a Hospital of University, on the March and May, 2021 and, have an ultrasound examination for the first time. Data were collected using the Personal Information Form, the Fear of COVID-19 Scale (FCV-19S), and the Parents’ Expectations, Experiences, and Reactions to Routine Ultrasound Examination Scale (PEER-U). The average age of pregnant women was 29.02±5.56. While 15.1% had a COVID-19 positive history, 8.4% lost someone they knew due to COVID-19. FCV-19S score was found 18.26±5.32. Fear of COVID-19 scores were higher in women who did not work and who had their first pregnancy.  While the mean score for PEER-U before was 59.05±6.99, the mean score for PEER-U after was 65.07±4.53. While a positive correlation was reported between FCV-19S and the scores for PEER-U before (r=0.392), no significant correlation was detected between FCV-19S and the scores for PEER-U after.  Pregnant women were found to experience an average fear of COVID-19. It was found a correlation between COVID-19 and the scores for PEER-U before. The fear of COVID-19 and the scores for PEER-U before were found to be affected by some socio-demographic characteristics.

Approaches to Conducting a Comparative Assessment of the Activities of Senior Officials and Executive Authorities of the Regions of the Russian Federation
Authors: Kryukov Sergey Vladimirovich
Published: August 2023

The subject of the study is approaches to conducting a comparative assessment of the activities of senior officials and executive authorities of the subjects of the Russian Federation. The object of the study is the regions (subjects of the Russian Federation). The author analyzes the main approaches to conducting such a comparative assessment, including those used in the Government Methodology for evaluating the activities of senior officials and executive authorities of the subjects of the Russian Federation. Based on the identified shortcomings of existing approaches, the author suggests a new approach to conducting a comparative assessment of the activities of senior officials and executive authorities of the subjects of the Russian Federation, based on the use of a minimum set of objective indicators characterizing the level and quality of life of the population of the subjects of the Russian Federation. The author's approach is based on the comparison of the level and quality of life of the population of the subjects of the Russian Federation as the main results of the activities of senior officials and executive authorities of the subjects of the Russian Federation. To assess the standard of living of the population of the region, it is proposed to use the indicator "the size of the real per capita income of the population", and to assess the quality of life of the population - the indicator "life expectancy at birth". For a visual comparison of regions in statics and dynamics, it is proposed to track the place and trajectory of the image of the region in the space of two coordinates corresponding to the level and quality of life of the population of the region. To differentiate regions in accordance with the results achieved, it is proposed to use a quantitative measure of the distance between the indifference curves in the specified coordinate space. Thus, the proposed approach has a number of advantages, and can be used both by the executive authorities of the subjects of the Russian Federation and by researchers to conduct a comparative assessment and choose ways to improve the level and quality of life of the population of the regions.
Numerical Modeling to Investigate the Aerodynamics of a Boundary-Layer Ingested Transonic Fan
Authors: Giri Ritangshu , Turner Mark G.
Published: August 2023

Boundary-layer ingested engines have the potential to offer significantly reduced fuel burn, but the fan stage must be designed to run efficiently with a distorted inflow. It must also be able to withstand unsteady aerodynamic loads resulting from a complex nonuniform flowfield. This paper applies different numerical methods for an improved understanding of the aerodynamic interaction between a transonic fan and inlet distortion. A single-stage transonic tail cone thruster fan was designed using both in-house and commercial tools operating in an inlet distortion flowfield. This paper demonstrates that the relevant metrics required to compute the aerodynamic performance of a fan stage in distorted conditions can be reasonably modeled with a few harmonics using the nonlinear harmonic method in a fraction of time in comparison to a full annulus time marching solution. The nonlinear harmonic method also reduces the computational domain, and hence reduces the solution runtime by an order of magnitude. However, it fails to accurately resolve the wake and potential field transfer across the blade rows due to a limited number of harmonics being applied. A detailed aerodynamic description of the unsteady inflow distortion, the interacting blade-row mechanisms, the flow redistribution upstream of the rotor, the distortion transfer across the different blade rows, and the corresponding aerodynamic losses can be analyzed accurately using only a full annulus time-marching method.
Euhemerics in early Ptolemaic Alexandria

The article presents a new original view on the circumstances and features of the origin of euhemerism in all its genre diversity - from mythographic utopias, chorographies and mirabilia to pseudoperiples and paradoxography. An in-depth analysis of the sources that have come down to us gives grounds to assume with a fairly high degree of probability early Ptolemaic Alexandria as its main launch pad and epicenter and to link it with the activities of Demetrius Phalereus, the founder of the famous in antiquity Mouseion and the Library.

The Reception of Aristotle’s Interpretation of Plato’s Forms in Plotinus and al-Fārābī
Authors:   University of Notre Dame, Alexandrov Emile
Published: August 2023

This paper makes four arguments to challenge attributing to Plato a theory of Forms. I begin by closely studying Aristotle’s critique of the Forms to show that Aristotle was more focused on the epistemological implications of the Forms as opposed to their existence. Additionally, it remains unclear as to whether Aristotle was targeting Plato or the Platonists in his critiques. I then turn to the inconsistencies inherent in Plato’s discussion of the Forms. Essentially, this is incumbent upon Plato’s commitment to the belief that writing and language fail to capture the Forms holistically. As such, Plato’s variegated discussions of the Forms in the dialogues reflect his commitment to the mutability of the world concurrently with language. This carries over to the reception of Plato and Aristotle in Antiquity and beyond. I show that starting from Antiochus of Ascalon onwards, Plato and Aristotle were accepted to be representatives of a consistent philosophy. This historical ‘harmonization’ of Plato and Aristotle shows that opposition between both thinkers concerning the Forms was not a commonly held view. I then turn to Plotinus who syncretised Plato’s Forms with Aristotelian Intellect which was appropriated by al-Fārābī who rejected the idea that there had been any distinction in the first place. Al-Fārābī composed a treatise on the harmony of Plato and Aristotle, whereas Plotinus based his entire philosophical enterprise on the synthesis of Platonic-Aristotelian philosophy that proved historically influential. The resulting thesis of this paper is that any close historical study of Aristotle’s interpretation of Plato’s Forms would show that one cannot attribute to Plato a theory of Forms without facing serious contradictions.
What is the reality of necessary and eternal truth? Metaphysical dispute of Jesuit theologians in the middle of the 17th century
Authors:   Saint Petersburg State University of Aerospace Instrumentation, Ivanov Vitaly ,   Institute of Philosophy RAS
Published: August 2023

The article is a study of the metaphysical dispute about the reality of necessary and eternal truths that took place among the leading Spanish Jesuits during the heyday of the scholastic tradition of the Society of Jesus in the middle of the 17th century. The traditional scholastic problem of “eternal truths” concerning essences of creatures and their possible existence, was radically reformulated thanks to the theological “innovations” of A. Pérez, who argued that the only verificativum (or foundation of reality) of any necessary truths is the very essence of God. This caused a furious polemical reaction on the part of S. Izquierdo, who proposed his own solution to this problem within the framework of his own original ontology of “status rerum” (especially the quidditative status) from the position of superrealism. The followers of Pérez, in turn, persistently opposed the "extremes" of Izquierdo's position. First, we briefly explicate the concept of "necessary and eternal truth" in Peripatetic tradition and give a historical overview of the time and place of this dispute, pointing to the main works in which the metaphysicians and theologians of the Society who participated in it formulated their positions. Secondly, we explicate the Pérezian thesis about God as the foundation of the necessity and reality of eternal truths on the example of an early treatise on the "possibility of creatures" by Gaspar de Ribadeneira (1653). Thirdly, we detail and analyze Izquierdo's criticism of this position in Disputation 10 of his Pharus scientiarum (1659). Fourthly, we present Izquierdo's own doctrine of the “quidditative status of things” or absolute necessary objective truths, and also explain his understanding of the necessity and eternity of such truths. In addition, we analyze how exactly he solves the key problem for his ontology – the problem of distinction and separability of the quidditative and existential status of a thing. Finally, we analyze the criticism of Izquierdo's position in the metaphysics of Antonio Bernaldo de Quirós (1666), pointing out the specifics of his argumentation and its theological and philosophical motives.
Eos and Tithonus: Metamorphoses of Corporeality
Authors:   Institute of Philosophy RAS, Petroff Valery V.
Published: August 2023

The article discusses the philosophical implications of the Greek myth of Eos and Tithonus. In relation to different versions of this myth, the opinions of various authors regarding the problem of finding and maintaining individual identity in the conditions of bodily metamorphoses, as well as the problems of aging (gradual loss of the body and memory) are considered. The question is raised about the body of the mythological hero and the means of transmitting the fabula, whether it is transmission in the oral tradition through speech-logos or transmission through the text fixed on a material carrier (which can be lost, corrupted, restored ). The question of the interrelation of the myth of Eos and Tithonus with the details of the biography of the authors who refer to it is being studied. In this respect, the following are studied: the Homeric hymn to Aphrodite, Sappho’s “Tithonus poem” (including the history of its finding and reconstruction), as well as the poem “Tithonus the Cicada” by Alexei Parshchikov, which puts the ancient story into the modern context of reasoning about the “digital body”, transhumanism and cloning.
Aristotle's observation of the illusion of the motion aftereffect in modern knowledge of the perception of time and movement
Authors:   Institute of Philosophy and Law SB RAS, Zaykova Alina
Published: August 2023

In his work De Insomniis, Aristotle pointed out that after observing motion, objects at rest appeared to move. In modern literature, this effect, called the "waterfall illusion" or "the motion aftereffect", is widely researched and explained both scientifically and philosophically. Most researchers consider in the first place why this happens and what it means. This allows us to put forward new hypotheses and argue in favor of existing theories, in particular, thanks to the waterfall illusion, a hypothesis about multi-threaded data processing by neurons was proposed and some features of the work of adaptive perception mechanisms were demonstrated. At the same time, the implicit and unreasoned choice of a specific method of explanation to assert the advantages of a certain model while neglecting other empirical experience may be a methodological error, which can be seen in the example of S. Prosser's concept of dynamic frames.
"Hellenic sages" in Christian temples: a guide to philosophical iconography in the Middle Age
Authors:   Saint Petersburg Mining University, Dorofeev Daniil
Published: August 2023

The article is devoted to the study of the visual-plastic iconography of ancient philosophers in medieval Christian churches in Western and Eastern Europe, the Middle East, Greece and Russia. For the first time in Russian and European scientific literature, the author gives such a complete and detailed overview of all Christian churches (including little-known ones) and temples that have visual-pictorial and sculptural-plastic images of “Hellenic sages”, which in the Middle Ages included not only ancient philosophers, but also poets, writers, historians and sibyls. Based on his many years of research, travel, study of many domestic and foreign sources on this topic, the author presents a large-scale and multicolored picture of the amazing Christian (primarily Orthodox) tradition of understanding the ancient sages as prophets of Christ and his teachings, drawing attention to many of its interesting features. This tradition finds expression both in texts and in the narthex, galleries, refectory, outer walls and even in the iconostasis of churches, visual images of the “Hellenic sages”, most often part of the iconography of the “Tree of Jesse”. Along the way, the problems of visual identification of such images, the features of their appearance, clothing, accompanying sayings, etc. are touched upon. Revealing in this way the potential of the visual dialogue between antiquity and Christianity in the Middle Ages, the author strives to present in a new light the reception of ancient Greek philosophers, which is valuable for modern thought both in the aesthetic and historical-philosophical context.

Published: August 2023

The article focuses on the genre and typological analysis of the early paintings of the “northern cycle” of the 1950s and 1960s by People’s Artist of the USSR Vladimir Igoshev, dedicated to the original world of the indigenous peoples of the North in the context of Soviet modernisation. This analysis of the works testifi es to the active entry of the “new life” images into the life and traditional culture of the indigenous northerners, and, at the same time, emphasises the originality of the ethnic fl avour. The article suggests the division of stable plots and themes into conditional groups: “new, socialist life” / “old, pre-revolutionary life”, school themes and the theme of enlightenment, pictures of cultural leisure and images of the “new man”. The author concludes that with the help of the works of V. Igoshev, it is possible to reconstruct the picture of the “Great Journey” of the indigenous peoples of the North in the context of the phenomena of Soviet modernisation.

THE ARTISTIC WORLD OF I. S. SHMELEV’S WORKS AS VIEWED BY LITERARY CRITICS IN CHINA
Authors: WANG ZEYU , WANG XIAOQIAN
Published: August 2023

The aim of the study is to determine the value of the artistic heritage of I. S. Shmelev in the eyes of Chinese critics in the process of creating spiritual realism as part of the literature of the Russian emigration. The article presents analysis of the current state of the study of I. S. Shmelev’s heritage in China. The authors identify possible directions of research on this writer among Chinese literary scholars. The scientifi c novelty of the work is due to the fact that studying of I. S. Shmelev’s works in the context of Christian traditions still remains on the periphery of the interests of researchers, and is practically not represented from the standpoint of Chinese literary scholars in terms of spiritual realism. For the fi rst time, a scientifi c rationale is given and a research development is carried out on the state of the study of the writer’s heritage at the moment in China. As a result, it is proved that the interest in research on Shmelev and his work is gradually changing in China.

THE HISTORIOGRAPHICAL REVIEW OF THE WORKS ON THE DEVELOPMENT OF RUSSIAN PAINTING IN THE SECOND HALF OF THE 18TH CENTURY
Authors: SADYROVA MARGARITA
Published: August 2023

Most often, Russian painting of the second half of the 18th century is considered in works on art only in the context of the general process of development of Russian art. Most of them conscientiously cover the development of Russian painting in the second half of the 18th century. The material on this topic is concentrated either in multi-volume publications, or in journal articles, or in separate books that tell about the life and work of a particular artist.
THE IMAGE AND MEANING OF THE MASK IN THE KOREAN BONGSAN MASK DANCE THEATRE
Authors: ARADZHIONI OKSANA
Published: August 2023

The complex of traditional meanings of the mask in the history of the Korean folk theater, which determined its appearance and ways of its involvement in the stage performance, is considered in comparison with modern reconstructions of performances of the Bongsan mask theater, one of the most famous types of Korean folk theater today. The analysis shows that among the historical meanings of the mask, the most popular among modern spectators are those meanings that are associated with the appearance of the mask as an object of decorative and applied art.
ORCHESTRATION AS A TEXTUAL INTERPRETATION OF A WORK (BASED ON V. PANCHENKO’S ARRANGEMENT OF THE CLAVIER OF E.-T.-A. HOFFMAN’S OPERA “UNDINE” FOR SOLOISTS, CHORUS AND SYMPHONY ORCHESTRA)
Authors: DARDA VALERIA
Published: August 2023

The continuing development of the composing technique is associated with the interpretation of timbre and other expressive possibilities of instruments and voices. At the same time, the displacement of concert performances of symphony orchestras and the tradition of creating “classical” orchestration by the practice of chamber-ensemble musicmaking and electronic musical creativity become topical problems. The question arises: has the attitude to the orchestration of music of the 18th-19th centuries changed today? What compromises are permissible, and what goes beyond the designated type of creative work? Do the ethical requirements to the composer’s text interpretation decrease when referring to the works of little-known authors? And if correctness and responsibility to the creator of the composition and the audience are great, then the role of research and analytical analysis multiplied by the mastery of the orchestration technology and talent compensate for the need to adapt the score to the proposed conditions of the work’s performance.
THE IMAGE OF SERVILIA IN THE COLLISIONS OF THE INTONATION PLOT: FROM THE DRAMA OF L. A. MEI TO THE OPERA OF N. A. RIMSKY-KORSAKOV
Authors: ISUPOVA TATIANA , OLEYNIK MARIANA
Published: August 2023

The presented materials are the fi rst experience of considering the musical characteristics of Servilia in the context of the intonational events of N. A. Rimsky-Korsakov’s opera of the same name, unfolding in the multidimensional space of its musical reality. The personal drama of the heroine is placed in socio-historical collisions: on the one hand, the confl ict of tyranny and citizenship, and on the other, the main socio-historical confl ict immersed in the deep layers and expressed in the confrontation between paganism and Christianity. The results of the study of the opera’s musical content testify to the modality of the musical image of the young patrician, consolidating the meanings of the intonational plot, and thus being the intonational epicenter of the opera.
THE NATIONAL AND THE UNIVERSAL IN CHEN YI’S WORKS
Authors: WU XIAOLEI
Published: August 2023

The article is devoted to Chen Yi, a Chinese violinist and composer living in the USA since 1986. Despite the worldwide fame, Chen Yi’s music has been little studied in Chinese and Russian musicology, except for individual works. Meanwhile, the expansion of knowledge about contemporary composers of China seems relevant for creating a general panorama of the Chinese musical culture of modern times. Many Chinese composers freely change their places of residence, tour all over the world, become honorary creative fi gures of different countries and at the same time remain dedicated to their native roots. Chen Yi’s work is an example of the commitment to the national culture, whose diverse images are embodied in the most striking modern stylistic solutions of the composer.
Reaction-Agnostic Featurization of Bidentate Ligands for Bayesian Ridge Regression of Enantioselectivity

Published: August 2023

Chiral ligands are important components in asymmetric homogeneous catalysis, but their synthesis and screening can be both time-consuming and resource-intensive. Data-driven approaches, in contrast to screening procedures based on intuition, have the potential to reduce the time and resources needed for reaction optimization by more rapidly identifying an ideal catalyst. These approaches, however, are often non-transferable and cannot be applied across different reactions. To overcome this drawback, we introduce a general featurization strategy for bidentate ligands that is coupled with an automated feature selection pipeline and Bayesian ridge regression to perform multivariate linear regression modeling. This approach, which is applicable to any reaction, incorporates electronic, steric, and topological features (rigidity/flexibility, branching, geometry, constitution) and is well-suited for early-stage ligand optimization. Using only a limited number of points per dataset, our workflow capably predicts the enantioselectivity of four metal-catalyzed asymmetric reactions. Uncertainty estimates provided by Bayesian ridge regression permit the use of Bayesian optimization to efficiently explore pools of prospective new ligands. Using this procedure, a new library of 312 chiral bidentate ligands was screened to identify promising ligand candidates for a challenging asymmetric oxy-alkynylation reaction.
Downsizing Porphyrin Covalent Organic Framework Particles Using Protected Precursors for Electrocatalytic CO2 Reduction

Covalent organic frameworks (COFs) are promising electrocatalyst platforms owing to their designability, porosity, and stability. Recently, COFs with various chemical structures were developed as efficient electrochemical CO2 reduction catalysts. However, controlling the morphology of COF catalysts remains a challenge, which can limit their electrocatalytic performance even if the chemical structure is optimally designed. Especially, while metalated porphyrinoids show great promise as catalytically active COF building blocks, their intermolecular stacking and coordination interactions make it difficult to conduct solution-based COF synthesis which can control the particle size dominated by the aggregation of crystallites. In this work, we report a new synthetic methodology for rationally downsized COF catalyst particles, where a tritylated amine is employed as a novel protected precursor for COF synthesis. Trityl protection provides high solubility to a representative cobalt porphyrin precursor, while its deprotection proceeds in situ under typical solvothermal COF synthesis conditions. This colloidal deprotection–polycondensation process yields smaller COF particles with less crystallite aggregation than a conventional synthesis, maintaining crystallinity and porosity. The downsized COF particles exhibit superior catalytic performance in electrochemical CO2 reduction, with higher CO production rate and faradaic efficiency with similar stability compared to conventional COF particles. The improved performance of downsized COF particles is attributed to the higher contact area with a conductive agent. This study provides a strategy for the preparation of COF electrocatalysts with controlled morphology and enhanced performance and also reveals an important factor in the evaluation of COF electrocatalysts.
