Authors: Ulianovska Yuliia , Firsov Oleksandr , Kostenko Victoria , Pryadka Oleksiy 
Published: June 2024

The object of the research is the process of identifying the authorship of a text using computer technologies with the application of machine learning. The full process of solving the problem from text preparation to evaluation of the results was considered. Identification of the authorship of a text is a very complex and time-consuming task that requires maximum attention. This is because the identification process always requires taking into account a very large number of different factors and information related to each specific author. As a result, various problems and errors related to the human factor may arise in the identification process, which may ultimately lead to a deterioration in the results obtained.
The subject of the work is the methods and means of analyzing the process of identifying the authorship of a text using existing computer technologies. As part of the work, the authors have developed a web application for identifying the authorship of a text. The software application was written using machine learning technologies, has a user-friendly interface and an advanced error tracking system, and can recognize both text written by one author and that written in collaboration.
The effectiveness of different types of machine learning models and data fitting tools is analyzed. Computer technologies for identifying the authorship of a text are defined. The main advantages of using computer technology to identify text authorship are:
– Speed: computer algorithms can analyze large amounts of text in an extremely short period of time.
– Objectivity: computer algorithms use only proven algorithms to analyze text features and are not subject to emotional influence or preconceived opinions during the analysis process.
The result of the work is a web application for identifying the authorship of a text developed on the basis of research on the process of identifying the authorship of a text using computer technology.
Determining the group of resource-oriented regions in the methodology of strategizing
Authors: Gerelishin R. I. 
Published: June 2024

Regions with significant natural resource potential play an important role in ensuring the energy and economic security of the Russian Federation. To maximize the effect of using resource potential, scientifically based and methodologically correct regional strategies must be developed. For these purposes, it is necessary to develop a concept for a strategy for the regional development of resource regions, for which it is proposed to use the strategizing methodology of a foreign member of the Russian Academy of Sciences, Professor V.L. Kvint. One of the first tasks when developing a concept is to identify a group of resource-oriented regions. To achieve this goal, the author’s definition of resource-oriented regions has been prepared, and based on an analysis of foreign and domestic practices, an algorithm for calculating the level of resource orientation has been proposed, based on 3 indicators: the share of mining in the gross regional product, the share of mining in the structure of regional employment and the degree of industry concentration. It is shown that for calculations using the proposed algorithm in terms of industry concentration, not only the Herfindahl–Hirmschan index can be used, but also the Shannon index, which is logically opposite to it, adapted for economic research.The calculations showed that the group of resource-oriented regions can include the Nenets, Yamalo–Nenets, Khanty–Mansiysk and Chukotka Autonomous Districts, the Republic of Sakha (Yakutia), as well as the Magadan and Sakhalin regions – these regions best meet the proposed definition of a resource-oriented region and can become the basis for developing the concept of a regional development strategy.
СООТНОШЕНИЕ ХРИСТИАНСТВА И КУЛЬТУРЫ В РЕЛИГИОЗНО-ФИЛОСОФСКИХ И ТЕОЛОГИЧЕСКИХ УЧЕНИЯХ XX СТОЛЕТИЯ
Authors: Положенкова Елена Юрьевна 
Published: June 2024

Целью данной статьи является культурфилософская рефлексия соотношения христианства и культуры в теологических и религиозно-философских учениях XX столетия (на примере учений С. Н. Булгакова, В. В. Зеньковского, Ж. Маритена, П. Тиллиха).
Методология. Авторы статьи исходят из признания двух противоположных методологических подходов, сложившихся в философской и религиозной мысли, к проблеме соотношения христианства и культуры: антиномистического, в котором религия и культура противопоставляются друг другу, и холистического, в котором выявляются их внутренние взаимосвязи и черты подобия.
Результаты. Было раскрыто, что вышеназванные мыслители исходят из признания глубокой связи христианства и культуры, рассматривая христианскую религию в качестве основания, духовного средоточия подлинной культуры, задающего ей высокое трансцендентное смысложизненное содержание. Общей чертой всех рассмотренных культурфилософских учений является понимание современного состояния культуры как глубокого кризиса, трагического противостояния религиозной и секулярной культур. Было выявлено, что характер интерпретации связей христианства и культуры, а также этиология кризисного состояния последней в рассмотренных культурфилософских учениях в значительной степени обусловлены конфессиональной спецификой (православной, католической, протестантской) мировоззрения их авторов.
Перспективы исследования. Проведённое исследование и его результаты могут способствовать нахождению путей преодоления современного глобального цивилизационного и ценностного кризиса, а также разработке теоретической модели православной культуры.
ЦИФРОВОЙ ПЕРЕХОД ЮЖНОРОССИЙСКИХ РЕГИОНОВ К ИМПОРТОЗАМЕЩЕНИЮ: УЧЕТ АСИММЕТРИИ ОТРАСЛЕЙ ВЫСОКИХ ТЕХНОЛОГИЙ
Authors: Волков Виталий Александрович 
Published: June 2024

Цель исследования — концептуальное и эмпирическое обоснование определяющей роли цифровой трансформации отраслей высоких технологий промышленного сектора регионов Юга России в формировании кратко- и долгосрочных сценариев их социально-экономического развития в рамках концептов информатизации, цифровизации и циркулярности с учетом высокой дифференциации этих территорий по экономическому, промышленному, инновационному и цифровому потенциалам.
Методологическая база исследования представляет собой конвергенцию ряда общесистемных теорий и концепций (системности, комплексности, сбалансированности, точек роста, инноватизации, цифровизации), а также импортозамещения, циркулярности, перехода к экономике предложения от экономики спроса, соответствия гипотезе взаимоувязанного и взаимосопряженного развития производственной и ресурсной экосистем региона. В процессе реализации задач и цели исследования использовался ресурсно-нормативный подход, сравнительный метод, динамический анализ.
Результаты исследования. В процессе исследования научно обосновано, что проводимая в настоящее время государственная политика структурного реформирования промышленности по модели импортозамещения с ключевой ролью высокотехнологичных отраслей определяется небывалым по масштабу запросом отечественной экономики в росте объемов производства высококонкурентной отечественной продукции, способной замещать существенно сократившийся импорт и повышать экспортный потенциал страны. Это согласуется с концепцией постепенного перехода от экономики спроса к экономике предложения. В статье обосновано, что «экономика предложения» (так современную российскую экономику характеризует Президент России В. В. Путин) детерминирует широкомасштабное развитие инновационного потенциала в отраслях высоких технологий обрабатывающих производств, а также не только освоение (внедрение), но и разработку прорывных (и подрывных) технологий, создание новых промышленных производств и отраслей, прежде всего в сферах, где имеется потенциал импортозамещения. В современной прикладной науке содержится обоснование того, что решение этих важнейших задач возможно исключительно на базе рационального распределения и использования эндогенных ресурсов (условие резильентности экономической системы) и в соответствии с гипотезой взаимоувязанного и взаимосопряженного развития производственной и ресурсной экосистем региона (гипотеза модели замкнутого цикла). В соответствии с этим автором предложена модель механизма последовательного цифрового перехода южнороссийских регионов к импортозамещению в индустриальной сфере с учетом существующей асимметрии отраслей высоких технологий.
Перспективы исследования заключаются в верификации разработанного механизма на примере регионов Юга России, а также научном обосновании возможности его тиражирования на другие регионы страны.

Оne of the most commonly used fluorine‑18 labeled prostate-specific membrane antigen (PSMA) ligands in positron emission tomography combined with computed tomography (PET/CT) is [18F]PSMA‑1007. In comparison to other clinically available PSMA radioligands characterized by renal clearance, [18F]PSMA‑1007 exhibits predominantly hepatobiliary excretion. It allows a better assessment of the pelvic area in patients with prostate cancer (PCa). Nevertheless, in our clinical practice, we routinely observed a notably high [ 18F]PSMA‑1007 uptake in the urinary bladder. The underlying reasons for this phenomenon remain inadequately explored.Purpose of the study. The purpose of this study was to assess the impact of preliminary hydration of patients on [18F]PSMA‑1007 uptake in the urinary bladder.Materials and methods. Prospective, multicenter, randomized controlled study included 180 patients with PCa who underwent [18F]PSMA‑1007 PET/CT. Scans were performed using three different PET/CT-systems: GE Discovery IQ Gen 2 (USA), Siemens Biograph 64 mCT and Biograph 64 TruePoint (Germany). All patients were divided into two groups: the group with hydration (n = 95, 53 %), which included the subgroups of patients with oral (n = 76, 80 %) and intravenous (n = 19, 20 %) routes of hydration, and the control group with no hydration (n = 85, 47 %). [18F]PSMA‑1007 uptake in the urinary bladder was quantified using SUVmean (Mean Standardized Uptake value), measured within a spherical VOI with a fixed volume of 2.5 cm3 delineating the bladder boundaries. Additionally, the TBRmean (Mean Target-to-Background Ratio), reflecting the ratio between urinary bladder and right gluteal muscles SUVmean.Results. SUVmean and TBRmean in urinary bladder were significantly lower (p < 0,001) in the group with hydration compared to the control group, with the following values: 1.3 [0.8; 2.0] versus 4.5 [2.7; 8.5] for SUVmean and 4.0 [2.3; 6.3] versus 13.0 [7.7; 24.0] for TBRmean. There was no significant differences in SUVmean and TBRmean between the subgroups with oral and intravenous routes of hydration (p = 0.95 for SUVmean, p = 0.49 for TBRmean). Additionally, comparatively lower interquartile range (IQR) values for both SUVmean and TBRmean in the group with hydration were noted: 1.2 versus 5.8 for SUVmean, 4.0 versus 16.3 for TBRmean.Conclusion. Preliminary hydration of patients in uptake period significantly reduces both the level and variability of [18F]PSMA‑1007 uptake in the urinary bladder.
A Note on Exact Closed-Form Solutions for Lamb’s Problem with an Arbitrary Poisson’s Ratio
Authors: Hu Shaoqian , Jiang Xiaohuan 
Published: June 2024

Abstract
Lamb’s Problem, a cornerstone in theoretical seismology, investigates the displacement of an elastic half-space due to surficial or buried point sources. Although the exact closed-form solution for surface displacements from surficial sources is well established, the solutions for buried sources in the 3D case have remained limited, either confined to integral forms or applicable only for certain Poisson’s ratios. This study addresses this gap by generalizing the existing closed-form solutions to accommodate Poisson’s ratio for buried sources. Our solutions are expressed in terms of elementary algebraic expressions, elliptic integrals, and Gauss hypergeometric functions. The derived solution is validated by numerical tests. With the newly derived solution, we also explore the properties of the leaking mode, which stems from the complex conjugate roots of the Rayleigh equation.

Authors: Kot Marek 
Published: June 2024

Financial frauds have been a growing problem across the global financial markets. Losses generated by such illegal activities affect both the global economy and individual entities, especially those operating in the financial market. Perpetrators of such frauds seem to always be one step ahead of the law enforcement, regulators as well as private sector entities such as banks and scientists. This review examines publishing actions taken throughout the years. It also shows whether there has been any correlation spotted between the number of papers published in a particular year and the events on the financial markets. The study involved a systematic literature review to achieve the set goals. Following the final results of the article, it is clear that the issue of financial frauds has been a growing global concern. It is crucial to strengthen the collaboration between the regulators, law enforcement, academic environment and private sector. Cooperation across the sectors should include research on how to prevent and mitigate the consequences of this kind of frauds.

Published: June 2024

<p>The 21st-century skills that students and teachers must have are literacy skills, learning skills and life skills. One of the literacy skills is mathematical literacy, also known as numeracy. This research aims to describe the numeracy knowledge profile of prospective mathematics teacher students. This type of research is quantitative descriptive research. The subjects of this research were 32 prospective mathematics teacher students at a private university in Yogyakarta. Data collection techniques in this research used questionnaires and interviews. The research results show that the majority of prospective mathematics teacher students are doubtful about their knowledge of numeracy. Furthermore, none of the students mentioned the complete meaning of numeracy skills; most only mentioned numeration as numbers and mathematical symbols, solving everyday problems, and number operations. Students are also unable to mention the content and context of numeracy questions. However, all students realize that as prospective mathematics teachers, it is important to study numeracy and implement it in the classroom. The suggestion to improve numeracy knowledge and skills are through lesson study that focuses on numeracy to introduce numeracy practices and as a model for prospective teachers, as well as using a student-centered learning approach, using real problems such as RME.</p><p><strong>BAHASA INDONESIA ABSTRACT: </strong>Kemampuan abad ke-21 yang perlu dimiliki oleh siswa dan guru adalah kemampuan literasi, kemampuan belajar, dan kemampuan hidup.

Abstract

Purpose
The research investigated the capacity of Myo-inositol (MI) in order that it improves biochemical markers in serum and follicular fluid, and ultimately, intracytoplasmic sperm injection (ICSI) outcomes of women with PCOS.
Methods
Sixty infertile patients with PCOS who were undergoing ovulation induction for ICSI, were randomly divided to two groups. The MI group received 2000 mg Myo-inositol + 1 mg folic acid twice a day for 6 weeks with starting the ICSI cycle. For the same period, the control group received a placebo containing only folic acid (1 mg). Levels of hormonal profiles in serum and follicular fluid, as well as oxidative stress markers (MDA, TAC, GPx, and SOD) were estimated using an ELISA assay. Primary end points were ICSI cycle outcomes.
Results
Compared to the placebo group, the MI group demonstrated significant reduction in serum and follicular fluid levels of LH, LH/FSH ratio, total testosterone, AMH, and Androstenedione. Furthermore, the MI group exhibited meaningful increases in TAC, GPx, and SOD, but MDA significantly decreased. While the number of recovered and mature oocytes is not similar statistically among the groups, the MI group showed significant improvements in the percentage of immature oocytes, cleavage rate, and good embryo quality. A meaningful correlation was checked between follicular fluid AMH level and LH, FSH, total testosterone, Androstenedione, insulin, MDA, the number of recovered oocytes, and immature oocytes.
Conclusion
Our outcomes indicate that Myo-inositol administration in women with PCOS undergoing ART helps to improve their hormonal profiles, and the quality of oocytes and embryos. (Trial registration: IRCT202220921056008N1)
