Activity of Russian Entrepreneurs in Field of Tea Production in Yangtze River Valley in Second Half of 19th Century
Authors: Khamzin I. R. , Ganiev R. T. , Kochnev A. V.
Published: December 2022

The development of the Russian tea industry in the Chinese provinces along the Yangtze River valley in the second half of the 19th century is examined in the article. It is noted that among the regions where Russian tea factories were located, the main role belonged to the province of Hubei, in addition, the presence of production in the provinces of Hunan and Jiangxi was revealed. The historical situation in which the Russian tea industry arose is studied. Based on archival and published material, the number of Russian factories in Central China is shown. It is revealed that in the 70s of the 19th century, Russian trading houses operating in China began to transfer factories from the interior of Hubei province to the port of Hankou. It has been determined that cheap brick tea has become the main commodity produced in Russian factories, while Russian entrepreneurs are gradually abandoning the production of long leaf tea. Separately, the features of tea production and the organization of the workflow were studied. It is proved that the Russian tea factory in China has become one of the important factors of not only economic, but also socio-cultural contact between Russian and Chinese civilizations.

Published: December 2022

Squamous cell carcinoma (SCC) is the most prevalent oral cancer within the population, representing approximately 90% of all oral neoplasms, and the lingual location is the most common site of the same, which usually presents with few symptoms which originates from presenting in advanced stages at the time of diagnosis. A case of an adult patient with a clinical and histopathological diagnosis of lingual carcinoma is reported. The study of these patients is important since they must remain in dental surveillance, not only in an early diagnosis of suspected premalignant and malignant oral lesions and timely treatment as appropriate, which improves their prognosis and quality of life.

One of the issues linked to Extension that has caused the greatest tension and evolutionary leaps in the University over the decades, had to do with its different currents of thought, from the traditionalist model to the critical model. Extension seemed at times to be shrouded in an "epistemological haze" that prevented a clear conceptual understanding of its changing paradigms and its role as an essential pillar of the public university. However, thanks to these processes of change and the countless positions produced in relation to the dialogue of knowledge, the participation of teachers and their responsibility to society in the framework of the public university was strengthened. From this and from political management decisions, the concept of curricularising extensionist praxis from the Chairs arose, also taking students centre stage, with the aim of continuing to prioritise this process during their undergraduate training. This new phenomenon at the Faculty of Dentistry of the National University of Cordoba presents us with a challenge in which, in addition to continuing to develop the usual territorial practices, the theoretical conceptualizations that will provide academic support for the dialogical exchange of knowledge with society should be positioned.

Authors:   Universidad Nacional de Córdoba, Virga Carolina , Aguzzi Alejandra , De Leonardi Adriana , Moro Cecilia
Published: December 2022

The process from an active ingredient to the final medicine requires pre-formulation and stability studies of the product developed under different conditions, as well as the standardization of the extract as raw material. The objective of this work was to characterize formulations for topical application (gels), for use in post-extraction tooth sockets. Materials and methods: The gels were made according to good laboratory practice standards. The pH of the gel formulations was measure with a pH meter (Eutech, Cyberscan) using 1% aqueous solutions of the gels at room temperature. Extensibility was determined with a wooden block and glass slide apparatus. The gel was added and the time it took too completely separate from the fixed was note. The spreading capacity was calculate using formulas (S = W × L / T) The measurement of the consistency of the gels was carried out by dropping a cone from a fixed distance of 10 cm in such a way that it lands in the center of a glass cup filled with the gel. Cone penetration was measured from the surface of the gel to the tip of the cone within the gel. The distance traveled by the cone after 10 seconds was recorded. To analyze the superficial topographic characteristics of the gels, photographs were taken with a confocal microscope. Results: All formulations are in a range of pH values close to neutrality (pH 6.4-6.9). The gel prepared with alendronate presented higher extensibility, while the others showed lower extensibility with similarities between them. The consistency analysis showed no differences between the formulations. The selected formulations presented a brown olive-green color with different intensities; they presented a homogeneous appearance to the naked eye, but heterogeneous when observed under a confocal microscope. Conclusions: In the characterization of the gels, show that they have a variable texture and consistency depends on the type and concentration of the active ingredient used. The most suitable gel formulation was alendronate.
RUU PERAMPASAN ASET SEBAGAI PELUANG DAN TANTANGAN DALAM PEMBERANTASAN KORUPSI DI INDONESIA
Authors: Agustine Oly Viana
Published: December 2022

ABSTRAKPemberantasan korupsi menjadi salah satu agenda reformasi dalam menciptakan penyelenggaraan negara yang bersih dan bebas korupsi. Berbagai upaya telah dilakukan pemerintahan dari masa ke masa mulai dari pembentukan Komisi Pemberantasan Korupsi dan diaturnya korupsi dalam sebuah peraturan perundang-undangan sendiri terlepas dari Kitab Undang-Undang Hukum Pidana. Kedua instrumen tersebut telah mampu menjadi harapan dalam pemberantasan korupsi di Indonesia. Meskipun demikian, perlu dipikirkan kembali instrumen lain yang dapat menjadi peluang dalam mempercepat pemberantasan korupsi di Indonesia. Dalam penulisan artikel ini akan membahas mengenai rancangan undang-undang perampasan aset sebagai peluang dan tantangan dalam pemberantasan korupsi di Indonesia. Metode penulisan yang digunakan adalah dengan yuridis normatif, dengan melihat peraturan perundang-undangan yang ada dengan ditunjang oleh teori-teori hukum yang ada. Hasil penelitian yang didapat bahwa rancangan undang-undang perampasan aset memiliki mekanisme khusus dalam pengembalian aset negara akibat dari korupsi tanpa adanya putusan pengadilan yang dapat membuat efek jera kepada para pelaku korupsi. Namun, tidak dipungkiri bahwa pemberlakuan perampasan aset masih mengalami stagnasi karena rendahnya political will dari para pembentuk undang-undang. Oleh karena itu, dapat disarankan kepada Pemerintah dan legislatif untuk dapat mendorong pembahasan dan pengesahan rancangan undang-undang perampasan aset segera. Kata Kunci: Korupsi, Peluang, Perampasan Aset, Tantangan.
KEDUDUKAN PERJANJIAN EKSTRADISI DAN PENGEMBALIAN ASET DALAM PENEGAKAN HUKUM PIDANA INTERNASIONAL TERHADAP PELAKU TINDAK PIDANA KORUPSI DI INDONESIA
Authors: Damayanti Novy Septiana
Published: December 2022

ABSTRAKPerjanjian ekstradisi memberi kemudahan kepada negara-negara yang memiliki perjanjian, dimana perjanjian tersebut untuk menindak, menangkap, dan mengadili pelaku kejahatan di suatu negara yang melarikan diri ke negara lain diluar yurisdiksi nasional. Kehadiran pelaku tersebut kenegara lain untuk menghindari upaya penangkapan atas dirinya sehubungan dengan kejahatan yang telah dilakukannya di negara asal. Maka dengan larinya pelaku keluar negeri, ini berarti ada negara lain yang kepentingannya dirugikan karena tidak dapat menangkap pelaku tersebut, yang dimana pelaku tersebut telah melakukan pelanggaran hukum berdasarkan tempat kejadian kejahatan yang dilakukan (locus delicti). Salah satunya adalah perkara tindak pidana korupsi dianggap sebagai ancaman kejahatan luar biasa yang merugikan seluruh masyarakat di dunia, dalam penegakkan hukum tindak pidana korupsi yang pelakuya melarikan diri keluar negeri agar dirinya merasa aman dan terbebas dari suatu tindak pidana yang ia lakukan. Maka ekstradisi dan pengembalian aset sangan diperlukan untuk para pelaku tindak pidana korupsi yang melarikan diri kenegara lain. Mekanisme dari bentuk kerjasama internasional dalam pengambilalihan aset tindak pidana dari negara lain sebagaimana yang diuraikan dalam pasal 43 (1) UNCAC sangat diperlukan. Dalam hal ini kedudukan perjanjian ekstradisi sangatlah penting untuk para pelaku tindak pidana korupsi yang melarikan diri kenegara lain. Penulisan ini menggunakan metode penelitian hukum yuridis normatif dengan penelitian dari data sekunder dan dijelaskan secara deskriptif. Sehingga pada akhirnya penulis berkesimpulan bahwa peraturan berupa pedoman terkait tindakan pengembalian aset dari tindak pidana korupsi yang ada di luar negeri lewat pengembangan perjanjian ekstradisi.

Well-Being Among Nursing Students: Relationship Between Lifestyle Behaviours, Sleep Quality and Resilience
Authors: Kundayi Ravi Ramya , mohamed mona
Published: December 2022

Well-being is considered a positive state influenced by one’s mental, physical, emotional and cultural factors. High-level well-being enables a person to live at full potential. In this study, we investigated the level of well-being and its associated factors among nursing students studying at a selected university in Ras Al Khaimah in the United Arab Emirates. A quantitative descriptive study was conducted among undergraduate nursing students enrolled in this university. A convenient sampling technique was used to recruit the participants. Measures included the WHO-5 well-being index, a lifestyle behaviour questionnaire, the Pittsburgh sleep quality index and a brief resilience scale. Nearly two-thirds (65.4%) of the study participants reported good well-being whereas the remaining 34.6% reported low well-being. In general, better well-being was found to be associated with moderate or vigorous physical activity for at least 30 minutes three or more times a week (
p<0.05) and a habit of skipping breakfast (
p<0.05). It was also found to be associated with better subjective sleep quality (
p<0.001), less sleep latency (
p<0.01), fewer sleep disturbances (
p<0.001), and less daytime dysfunction (
p<0.001). These results support the need to improve the well-being of nursing students. We recommend interventions that promote physical activity and sleep quality to improve the well-being of undergraduate nursing students.

The article was prepared on the empirical database of a sociological survey of schoolchildren’s parents in the Novosibirsk region. Re- 184 search tasks included the following: to involve opinion of parents about the ongoing changes in the Russian school system, about the quality of education, opportunities for personal progress in the framework of modern conditions, as well as about future plans and choice of profession. To obtain empirical information, a mixed technique was used: telephone survey (in the urban agglomeration) and traditional with a paper questionnaire (in 2 municipal districts of the region). In total, in 2018–2019 505 questionnaires were collected (data combined into one array). Most of the respondents generally answered well or rather well about the school where their child (or children) study, but very critically appreciated the results of the educational reforms being carried out in the country. At the same time, parents made a request to improve the quality of school education, reduce formalism in the educational process, increase the professionalism of teachers, improve methods, programs, textbooks and organization of the educational process, and they also expressed interest in expanding the areas of additional classes that develop the interests of schoolchildren. The vast majority of parents are sure that in modern Russian society the financial situation of the family is not decisive for the opportunities for the intellectual development of children, and it is also not necessary for this to live in a large city. Much more important, in their opinion, is the ability of the child and his (her) desire to study, as well as the efforts of the family aimed at the development of children, the cultural level and education of parents, as well as the quality of school education.

Published: December 2022

The article examines the peculiarities of the social status of teachers of humanities working in Russian universities. The processes taking place today in modern society have changed the social status of university teachers, depending on the type of university in which they work, their age and position. This especially affected teachers of social and humanitarian disciplines. There is an asymmetry in their status position, in which a high level of education conflicts with a low level of financial status of this category of people, which leads to a decrease in the public prestige of the profession. The data of the All-Russian sociological study “Humanities teachers of Russian universities: socio-political values, forms of social activity, effects of influence on youth”, conducted in September – October 2021 under the guidance of Doctor of Sociology, Professor of Ulyanovsk State Technical University O.V. Shinyaeva, are presented.

Authors:   Omsk State Technical University, Evdokimova O. P. , Makashin D. S. ,   Omsk State Technical University
Published: December 2022

Aluminum alloy Ak5m is widely used in the aerospace and automotive industries to replace heavier alloys. This is due to its excellent properties of high specific strength, high corrosion resistance, good formability and low manufacturing cost. Ductility and heat generation during drilling AK5MCH often leads to the formation of burrs at the inlet and outlet from the surface of the workpiece. This study shows the effect of cutting speed and drilling conditions on the formation of burrs in the AK5MCH alloy. Drilling is carried out using coolant and without coolant using drills made of high-speed steel with a diameter of 6,0 mm with cutting speeds of 20, 42 and 60 m/min at a constant feed of 0,15 mm/rev. This study showes that drilling AK5MCH with a cutting speed of 42 m/min using a coolant is advantageous, as it leads to the least tool wear and minimal burr formation.

Published: December 2022

Theoretical studies of the endurance of an aviation alloy of AMg6 type during its long-term cyclic volumetric temperature deformation beyond the limits of Hooke's law have been carried out. A technique has been developed for assessing the endurance of aviation alloys in cyclic volumetric temperature deformation taking into account the presence of cavities (cracks) based on bringing the cyclic volumetric temperature deformation conditions to the conditions of standard mechanical testing of samples. According to the developed method, a preliminary assessment of the endurance of the aviation alloy of AMg6 type with a workhardened and annealed surface is carried out using the available limited base of empirical data obtained on the basis of standard mechanical tests of experimental samples. The effect of the initial length of a crack in experimental samples on the endurance of the experimental samples, at which its uncontrolled growth is possible during cyclic volumetric temperature deformation, is assessed. A comparative analysis of the calculated endurance of the experimental samples with the actual endurance of the structural material (hard worked alloy AMg6) of a real orbital object such as the «Zarya» module of the international space station shows a discrepancy of no more than 12,5 %.

Published: December 2022

The article is devoted to one of the important problems of increasing the wear resistance of tribosystems by applying an antifriction polymer composite coating containing a groove that operates in a hydrodynamic mode to the tribocontact surface. Based on the equation of the flow of truly viscous liquid for a «thin layer» and the continuity equation, a self-similar solution is found taking into account the groove and without taking into account the groove, as a result, the velocity and pressure fields in the groove and on the surface of the polymer antifriction composite coating are determined, as well as the load capacity and friction force allowing to determine the increase in wear resistance; an increase in duration of the hydrodynamic regime. The results of numerical analysis of the obtained theoretical calculation models and experimental evaluation of the proposed design are also presented in order to verify and confirm the effectiveness of the obtained theoretical models.

Published: December 2022

The paper considers a method for justifying the choice of a corrosion-resistant material for the manufacture of a blowout preventer body based on computer simulation of an elastic-plastic task in the ANSYS Mechanical APDL software. To describe the material properties, a multilinear deformation model is used, the reference points of which are calculated as a result of working out the macro developed by the authors based on two models: RambergOsgood and the “method of sequential corrections” proposed by TSAGI specialists. The paper presents the results of computer simulation on the loading of the PShKM-ASMT-114x21 preventer body by working and double starting pressure for four variants of body materials. The calculations confirmed the high safety factor of the body for the currently used 40X steel showed sufficient working capacity of corrosion-resistant steels 20X13 and 30XMA. However, a computer experiment detected very extensive zones and the level of plastic strains as a result of loading the body made of 12X18H10T steel with double starting pressure. The obtained results indicate that the investigated preventer can be manufactured in corrosionresistant versions K1 and K2, but for the execution of K3 it is necessary to develop a fundamentally different geometry of the body.

A promising design of a thermostated quartz oscillator with a resonator-thermostat is considered. In order to study the effect of replacing the material of the microplate in the resonator-thermostat on the operation of the generator, the processes of establishing a stationary temperature regime after switching on are investigated. The material of the new microplate corresponds to the technology of lowtemperature co-fired ceramics. An unacceptable change in the nature of the establishment of a stationary regime has been detected. To solve the problem found, the design change is proposed.

Magnetic testing is one of the most widespread types of the NDT. When carrying out magnetic testing various analog magnetic measuring sensors are used: ferroprobe, based on Gauss and Hall effects, etc. A perspective direction of research in the field of nondestructive testing and technical diagnostics is the development of measuring transducers with a digital output signal, or a signal easily convertible into a code. The paper considers magnetic transducer based on the oscillistor effect, which has a threshold nature and involves the appearance of electric current oscillations, flowing through a semiconductor sample, placed in the longitudinal electric and magnetic fields. The results of experimental studies of the dependence of the threshold electric field strength on the magnetic field strength are presented. The scheme of the converter of magnetic field induction into the impulses of electric voltage, and diagrams of its work are given. The sensitivity of the converter depends on the frequency of the sample frequency generator and the conversion coefficient of the ramp generator.

Published: December 2022

Phalangeal microgeodic syndrome (PMS) is a rare rheumatological disease affecting children strongly associated with cold weather. It is considered to be benign and self-limiting, with most cases resolving in warmer months, and no studies have investigated its association to autoantibodies or viral infection. In this peculiar case, a 12-year-old child with the previous COVID-19 infection developed PMS that did not improve in the warm weather and, subsequently, Raynaud’s phenomenon and facial rash. With the increasing number of new studies showing the correlation between COVID-19 and autoimmunity, this case report highlights a plausible link between COVID-19, PMS, and autoimmunity in the pediatric population that should be investigated further.

Published: December 2022

According to WHO data, in 2016 the number of adults with excess body weight exceeded 1.9 billion (39 % of the inhabitants of our planet over the age of 18), of which more than 650 million (13 %) suffer from obesity. Due to the high prevalence, doctors meet more and more patients with overweight and obesity, and they need nutritional correction at the pre-hospital stage. Obesity as a result of overeating, but paradoxically, can be accompanied by nutritional deficiency, therefore nutritional deficiency is determined not only by low body weight, but also by the inability to maintain the optimal internal state of the body. Patients with overweight and obesity should be screened and examined according to such criteria (validated scales MUST and NRS-2002) that are used in general clinical practice, for a certain disease, and as a screening for nutritional insufficiency/inadequacy of nutrition. The publication used articles that are included in scientific search databases Cochran, GoogleScholar, PubMed.

Published: December 2022

A full-scale russian-Ukrainian war has been going on for about nine months. Almost every day, Ukrainian cities suffer from enemy raids of missiles and drones, as a result, civilians become victims of hostilities. The prevalence of mine blast injury in these conditions is extremely high. Unfortunately, this type of injury is often accompanied by massive bleeding, which forces to make amendments in a treatment strategy. According to world standards, the first infusion solution for this category of patients should be whole blood, because of its numerous advantages. At the Multidisciplinary Clinical Hospital of Emergency and Intensive Care in Lviv, this strategy has been used almost since the first days of the war for patients of all age groups. In the article, we present a convincing evidence base of the advantages of using whole blood, as well as a clinical case of using whole blood infusion in a pediatric patient.
Anglicismes en russe doukhobor
Authors: MAKAROVA Veronika
Published: December 2022

Cet article examine les anglicismes en russe doukhobor, une variété linguistique qui était parlée au Canada par les Spirit Wrestlers (ou Doukhobors, un groupe de dissidents chrétiens originaire de l'Empire russe et immigré au Canada en 1899), mais qui a presque entièrement disparu. Les résultats démontrent l’existence de trois vagues successives d’emprunts à l’anglais. La première (contenant très peu d’emprunts, composés principalement de gentilés) s’était déjà produite en russe avant l’immigration des Doukhobors au Canada. La deuxième vague a correspondu aux premières années de leur immigration, lorsque des dizaines de mots ont été empruntés à l’anglais, principalement pour exprimer certains nouveaux concepts liés à la vie dans leur nouveau pays : la technologie, la vie sociale, le vocabulaire général, la culture, les unités de mesure et le vocabulaire lié à l’alimentation. La dernière vague, à la fin du XXe et au début du XXIe siècles, était principalement composée d’emprunts de termes technologiques. Seule la deuxième vague a été prolifique et a créé de nouveaux mots à partir de mots sources anglais par le biais d’une dérivation morphologique. L’utilisation de mots d’emprunt qui sont absents dans le russe standard a contribué à l’idée selon laquelle le russe doukhobor était une variété linguistique inférieure. Cette notion, ainsi que certains facteurs démographiques et sociaux plus saillants, ont joué un rôle dans sa disparition.
“Mit dem Topping bin ich auch fein”–Anglicisms in a German TV cooking show
Authors: FIEDLER Sabine
Published: December 2022

En raison de son rôle de lingua franca, l’anglais est une source majeure d’influence linguistique dans le monde entier. Cet article traite de l’impact de l’anglais sur l’allemand. Les influences induites par le contact ont été largement décrites pour des domaines comme le commerce, le sport, le divertissement, la publicité et la politique. L’accent est mis ici sur un domaine traditionnellement associé à la langue française – la cuisine. Il présente les résultats d’une étude empirique sur l’utilisation des anglicismes dans une émission de cuisine de la télévision allemande. En Allemagne, ce format connaît un regain de popularité et constitue une base utile pour cette étude car il représente un type de communication orale qui est perçu comme authentique et se rapproche de la communication spontanée et naturelle. Les anglicismes trouvés dans l’ensemble de données comprennent des emprunts directs, des emprunts traduits (calques) et des constructions hybrides. Alors que la majorité d’entre eux sont des lexèmes simples et complexes, tels que peppern (« poivrer ») et Signature-Gericht (« plat signature »), plus d’un tiers peuvent être classés comme des unités phraséologiques ayant la structure de syntagmes (p. ex. in the making) et de phrases (p. ex. Safety first!). Les buts comunicatifs des émissions de cuisine sont l’instruction et le divertissement, et l’utilisation des anglicismes y est étroitement liée. Par exemple, les anglicismes servent à dénommer les produits et les plats (p. ex. green-zebra Tomaten, Surf and Turf, No-bake Cheesecake), sont utilisés pour combler les lacunes de l’émission lorsque les gens ne savent peut-être pas quoi dire ou comment réagir (p. ex. That’s life), et on les retrouve fréquemment dans les jugements positifs et négatifs (p. ex. ein Masterpiece, ein bisschen Old School). En outre, les animateurs insèrent des expressions anglaises pour donner à leur discours un caractère plus vivant, moderne et familier et pour créer un humour basé sur la langue.
Fractional differential model of physical processes with saturation and its application to the description of the dynamics of COVID-19
Authors: Твёрдый Д.А. , Паровик Р.И.
Published: December 2022

В этой статье была использована дробно-дифференциальная модель физических процессов с насыщением для описания динамики летальных исходов инфекции COVID-19. Математическое описание модели дается интегро-дифференциальным уравнением Риккати с производной дробного переменного порядка типа Герасимова-Капуто. Такое описание позволяет учитывать эффекты насыщения и памяти в динамике распространения COVID-19 среди населения. Здесь эффект насыщения заключается в выходе на плато числа заболевших и умерших, что указывает на стабилизацию динамики распространения COVID-19. Эффект памяти заключается в том, что симптомы инфекции у зараженных проявляются не сразу, а с некоторой задержкой. В статье исследуются данные наблюдений по новым случаям заражения и общему числу смертей в период за 2.5 года (с марта по сентябрь 2022 г) в Российской Федерации и Республике Узбекистан. Далее в работе уточняются параметры модели на основе исследуемых данных по динамике COVID-19. С помощью уточнённой модели делается предварительный прогноз на следующие полгода с последующей проверкой. Показано хорошее согласие между модельными кривыми и кривыми данных по общему числу смертей от COVID-19.

In this article, a fractional differential model of physical processes with saturation was used to describe the dynamics of lethal outcomes of COVID-19 infection. The mathematical description of the model is given by the integro-differential Riccati equation with a derivative of a fractional variable order of the Gerasimov-Caputo type. This description makes it possible to take into account the effects of saturation and memory in the dynamics of the spread of COVID-19 among the population. Here, the saturation effect consists in reaching a plateau in the number of cases and deaths, which indicates the stabilization of the dynamics of the spread of COVID-19. The memory effect is that the symptoms of infection in infected people do not appear immediately, but with some delay. The article examines observational data on new cases of infection and the total number of deaths over a period of 2.5 years (from March to September 2022) in the Russian Federation and the Republic of Uzbekistan. Further, the parameters of the model are refined based on the studied data on the dynamics of COVID-19. With the help of the refined model, a preliminary forecast for the next six months is made with subsequent verification. Good agreement is shown between the model curves and the data curves for the total number of deaths from COVID-19.

Authors: Богатырева Ф.Т.
Published: December 2022

В работе исследуется параболическое уравнение в частных производных с дробным дифференцированием по одной из двух независимых переменных, ассоциируемой со временем. Такие уравнения принято относить к классу уравнений дробной диффузии. Оператор дробного дифференцирования представляет собой линейную комбинацию двух операторов Джрбашяна-Нерсесяна. Основным результатом работы является теорема об общем представлении регулярных решений исследуемого уравнения в бесконечной полосе. В терминах функции Райта построено фундаментальное решение и изучены его основные свойства. В частности, доказаны формулы дробного дифференцирования, исследовано асимптотическое поведение и получены оценки для фундаментального решения и его производных при больших и малых значениях автомодельной переменной, доказана его положительность. Для построения общего решения использован метод функции Грина, адаптированный к уравнениям, содержащим операторы Джрбашяна-Нерсесяна. К частным случаям рассматриваемого уравнения относятся уравнения с производными Римана-Лиувилля и Герасимова-Капуто. Поэтому полученные результаты остаются справедливыми и для уравнений с этими операторами дробного дифференцирования и их комбинациями.

The paper investigates a parabolic partial differential equation with fractional differentiation with respect to one of two independent variables associated with time. Such equations are usually referred to the class of fractional diffusion equations. The fractional differentiation operator is a linear combination of two Dzhrbashyan-Nersesyan operators. The main result of the work is a theorem on the general representation of regular solutions of the equation under study in an infinite strip. A fundamental solution is constructed in terms of the Wright function and its main properties are studied. In particular, formulas for fractional differentiation are proved, the asymptotic behavior is investigated, and estimates are obtained for the fundamental solution and its derivatives for large and small values of the self-similar variable, and its positiveness is proved. To construct a general solution, the Green’s function method adapted to equations containing Dzhrbashyan-Nersesyan operators is used. Particular cases of the equation under consideration include equations with Riemann-Liouville and Gerasimov-Caputo derivatives. Therefore, the results obtained remain valid for equations with these fractional differentiation operators and their combinations.

This paper is devoted to the process of finding the upper bound for the absolute error of the optimal quadrature formula in the space W2​​(m,m−1) of real-valued, periodic functions. For this the extremal function of the quadrature formula is used. In addition, it is shown that the norm of the error functional for the optimal quadrature formula constructed in the space W2​​(m,m−1)is less than the value of the norm of the error functional for the optimal quadrature formula in the Sobolev space L2​​(m).

Пусть G – подгруппа в группе всех обратимых линейных преобразований конечномерного действительного пространства Rn. Одной из задач дифференциальной геометрии является нахождение легко проверяемых необходимых и достаточных условий, обеспечивающих G – эквивалентность путей, лежащих в Rn. В статье установлены необходимые и достаточные условия эквивалентности путей в некоторой неевклидовой геометрии.

Let G be a subgroup of the group of all reversible linear transformations of a finitedimensional real space Rn. One of the problems of differential geometry is to find easily verifiable necessary and sufficient conditions that ensure that G is the equivalence of paths lying in Rn. The article establishes the necessary and sufficient conditions for the equivalence of paths in some non-Euclidean geometry.

Published: December 2022

В работе исследуется нелокальная краевая задача для линейной системы обыкновенных дифференциальных уравнений дробного порядка с постоянными коэффициентами на отрезке [0,l]. Дробная производная порядка α∈(0,1] понимается в смысле Римана–Лиувилля. Краевые условия связывают след дробного интеграла от искомой вектор-функции на левом конце отрезка – в точке x=0, со следом самой вектор функции на правом конце отрезка – в точке x=l. Цель настоящей работы – построение явного представления решения данной задачи в терминах функции Грина. Исследована структура решения краевой задачи, определена и построена соответствующая функция Грина, получено представление решения. Доказана теорема об однозначной разрешимости исследуемой краевой задачи.

We study a nonlocal boundary value problem for a linear system of ordinary differential equations of fractional order with constant coefficients on the interval [0,l]. The fractional derivative of order α∈(0,1] is understood in the Riemann–Liouville sense. The boundary conditions connect the trace of the fractional integral of the desired vector function at the left end of the segment – at the x=0, with the trace of the vector function itself at the right end of the segment at the point x=l. The purpose of this work is to construct an explicit representation of the solution of this problem in terms of the Green’s function. The structure of the solution to the boundary value problem is investigated, the corresponding Green’s function is defined and constructed, and the representation of the solution is obtained. A theorem on the unique solvability of the boundary value problem under study is proved.
Data-driven discovery of organic electronic materials enabled by hybrid top-down/bottom-up design

The high-throughput molecular exploration and screening of organic electronic materials often starts with either a 'top-down' mining of existing repositories, or the 'bottom-up' assembly of fragments based on predetermined rules and known synthetic templates. In both instances, the datasets used are often produced on a case-by-case basis, and require the high-quality computation of electronic properties and extensive user input: curation in the top-down approach, and the construction of a fragment library and introduction of rules for linking them in the bottom-up approach. Both approaches are time-consuming and require significant computational resources. Here, we generate a top-down set of 117K synthesized molecules containing their optimized structures, associated electronic and topological properties and chemical composition, and use these structures as a vast library of molecular building blocks for bottom-up fragment-based materials design. A tool is developed to automate the coupling of these building block units based on their available C(sp2/sp)-H bonds, thus providing a fundamental link between the two philosophies of dataset construction. Statistical models are trained on this dataset and a subset of the resulting hybrid top-down/bottom-up compounds, which enable on-the-fly prediction of key ground state (frontier molecular orbital gaps) and excited state (S1 and T1 energies) properties from molecular geometries with high accuracy across all known p-block organic compound space. With access to ab initio-quality optical properties in hand, it is possible to apply this bottom-up pipeline using existing compounds as molecular building blocks to any materials design campaign. To illustrate this, we construct and screen over a million molecular candidates for efficient intramolecular singlet fission, the leading candidates of which provide insight into the structural features that may promote this multiexciton-generating process.
Strained Porphyrin Tape-Cycloparaphenylene Hybrid Nanorings

Published: December 2022

V-shaped porphyrin dimers, with masked para-phenylene bridges, undergo efficient oxidative coupling to form meso-meso linked cyclic porphyrin oligomers. Reductive aromatization unmasks the para-phenylenes, increasing the strain. Oxidation then fuses the porphyrin dimers, providing a nanoring with curved walls. The strain in this macrocycle bends the para-phenylene and fused porphyrin dimer units (radii of curvature: 11.4 Å and 19.0 Å, respectively), but it does not significantly alter the electronic structure of the fused porphyrins.

Due to the rise in atmospheric carbon dioxide (CO2) concentrations, there is a need for the development of new strategies to enhance the selectivity and activity of the electrocatalytic conversion of CO2 to value-added products. The incorporation of redox mediators (RMs) as co-catalysts to enhance the transfer of redox equivalents during catalysis has been gaining more attention in recent years across a variety of small molecule transformations. We have shown that using Cr-centered complexes with sulfone-based RMs leads to an enhancement of CO2 reduction electrocatalysis under protic conditions via an inner-sphere mechanism. In these co-catalytic systems, an oxygen atom of the reduced RM binds to the Cr center to form a key intermediate stabilized by pancake bonding between the reduced aromatic components of the catalyst ligand backbone and the RM. This interaction facilitates the transfer of an electron and accesses a more kinetically favorable reaction pathway. Here, we show that expanding the aromatic character of the ligand backbone of the catalyst as well as the RM can cause a greater enhancement of co-electrocatalytic activity. These results suggest that further activity improvements can be achieved by focusing on the kinetic and thermodynamic parameters which control association between the catalyst and RM.
