The paper is devoted to the analysis of the influence of the galactic bar on the nature of the orbital motion (chaotic or regular) of globular clusters in the central region of the Galaxy with a radius of 3.5 kpc, which are subject to the greatest influence of the bar. The sample includes 45 globular clusters. To form the 6D phase space required for integrating the orbits, the most accurate astrometric data to date from the Gaia satellite (Vasiliev, Baumgardt, 2021) were used, as well as new refined average distances (Baumgardt, Vasiliev, 2021). The orbits of the globular clusters were obtained both in an axisymmetric potential and in a potential including the bar. The following, most realistic, bar parameters were adopted: mass 1010M⊙, semi-major axis length 5 kpc, bar axis rotation angle 25o, angular otation velocity 40 km/s/kpc. The analysis of the chaoticity/regularity of the orbital motion in both potentials was carried out using one of the most effective methods, namely, the frequency method, which consists in calculating the drift of fundamental frequencies. As a result, the influence of the bar on the dynamics of each GC of the sample was assessed. We ectablished that 8 GCs changed regular dynamics to chaotic under the influence of the bar, and 9 GCs changed chaotic dynamics to regular.

In recent years, A2 parameter determinations became available for many asteroids due to astrometric measurements’ quantity and quality improvement. It is well known that the A2 parameter is associated with the influence of the Yarkovsky drift of asteroid orbits. The mentioned A2 determinations can be performed using a 50-year (or even less) time series of positional data for relatively small asteroids (with a size of about hundreds of meters). These calculations meet many difficulties for larger bodies (more than 10 kilometers). Logically, a relatively long time series with 100-year coverage leads to a significantly good effect manifestation. The (433) Eros asteroid is an illustrative case in the considered context. It has a long history of observations (since the 1890s). Unfortunately, the (O-C) dispersion for old observations reaches several arc seconds. Therefore, A2 value estimation for this body is complicated. Digitization of the corresponding old photographic plates and remeasurements of the asteroid positions are required. We present the results of the remeasurements of the Pulkovo photographic plates containing (433) Eros images. These astronegatives were taken with the Pulkovo Normal Astrograph in 1900 and 1930. Digitization was performed with the NAROO digitization center (Paris Observatory). A total of 18 asteroid positions were obtained at the accuracy level of 0.1 - 0.3 arcsec. The absolute values of (O − C)α and (O − C)δ do not exceed 0.5 arcsec relative to the NASA/Horizons ephemerides.

This article studies the relativistic effect of geodetic precession in the rotation around their axes of Jupiter and its 94 satellites for which ephemerides are known. As a result, the most significant secular terms of the geodetic rotation of these celestial bodies were determined for the first time: 1. for Jupiter relative to the barycenter of the Solar System and the plane of the mean orbit of Jupiter at the epoch J2000.0 in Euler angles, in the perturbing terms of physical libration and in the absolute value of the vector of angular rotation of the geodetic rotation of the body under study; 2. for 8 regular (4 inner (Metis J16, Adrastea J15, Amalthea J5 and Thebe J14)) and 4 Galilean (Io J1, Europa J2, Ganymede J3 and Callisto J4))) satellites of Jupiter relative to: a) the barycenter of the Solar system and the plane of the mean orbit of the satellite under study at epoch J2000.0 in Euler angles, in the perturbing terms of the physical libration and in the absolute value of the vector of angular rotation of the geodetic rotation of the body under study; b) the barycenter of the Solar system and the plane of the mean orbit of the barycenter of the Jovian system at epoch J2000.0 in Euler angles, in the perturbing terms of the physical libration and in the absolute value of the vector of angular rotation of the geodetic rotation of the body under study; c) the barycenter of the Jupiter satellite system and the plane of the mean orbit of the studied satellite of the J2000.0 epoch in the perturbing terms of the physical libration and in the absolute value of the angular rotation vector of the geodetic rotation of the studied body; 3. for 86 irregular satellites (J6–J13, J17–J72, J5501–J5507, J5509–J5523) of Jupiter relative to: a) the barycenter of the Solar system in the absolute value of the angular rotation vector of the geodetic rotation of the studied body; b) the barycenter of the Jupiter satellite system in the absolute value of the angular rotation vector of the geodetic rotation of the studied body. For the J2000.0 epoch, the mean orbits of the studied celestial bodies and the mean orbit of the barycenter of the Jovian system were calculated. For regular satellites, the values of the angles of inclination of their equator to their own orbits were determined. The obtained analytical values of the geodetic precession of the studied celestial bodies can be used for a numerical study of the rotation of these bodies in the relativistic approximation.

This study considers the elemental composition and manufacturing technology of mirrors of the so-called Sarmatian type. The examined mirrors are fortuitous discoveries originating from the territory of the Kerch Peninsula. All three objects are pendant mirrors with radial-beam ornamentation, which appeared at the turn of the 1st and 2nd centuries AD and existed until the beginning of the 3rd century AD. The results of X-ray fluorescence analysis of the alloy composition indicate that the mirrors are made of an alloy of copper, tin and lead with similar qualitative characteristics. The method of X-ray tomography clarified the details of the relief ornamentation, which was poorly expressed on the items due to corrosion.

This is the first report on the isolation of Rhodococcus aetherivorans-specific bacteriophages and of applicability of such invertebrates as Hyalophora cecropia and Eisenia fetida as objects for screening the phage microflora of Rhodococcus species. Some of the isolated phages were capable of growth of R. ruber and R. qingshengii. An efficient procedure for bacteriophage reproduction in the liquid culture of R. aetherivorans was developed. The revealed bacteriophages may be used for development of efficient genetic tools for Rhodococcus strains, including the industrially significant ones.
Litholigical features of the eastern edge of the Miocene sulfate basin in Prut-Dniester interfluve and the specifics of karstification
Authors: Kostiuk Uliana
Published: December 2024

The entire sulfate layer of the western Ukraine is divided into units (lithosomes) that define specific conditions of sediment accumulation in each area.

Our research is focused on studying the structural-textural features of the gypsum layer at the edge of the evaporite basin on the Prut-Dniester interfluve and tracing their influence on the development of karst manifestations, both surface and underground.

The lithological characteristics of evaporites in this area were studied by T. Perita and M. Bombel. The latter assigned the eastern edge of the Miocene sulfate basin to unit M, which is entirely represented by a facies of concealed crystalline gypsum with traces of gypsumified microbial mats. This facies is typical for coastal plains of a saline basin, as colonies of cyanobacteria settle in shallow waters under warm climatic conditions, and upon the influx of sulfate solution, these cyanobacteria undergo gypsyfication. Thus, the facies of concealed crystalline gypsum with a wavy structure formed due to the gypsyfication of cyanobacteria in the coastal zone.

Regarding karst manifestations, the investigated area is home to two giant labyrinthine caves: Popelyushka Cave (91 km) and Bukovinka Cave (5 km). These caves serve as classic examples of hypogenic speleogenesis. The morphology of the caves, including ceiling domes, overhanging walls, windows, etc., indicates the formation of galleries by the influx of artesian chemically active waters.

We conducted research to refine the litho-facial features of the territory. The speleological method was employed, as it allows for observing differences in the gypsum layer on uneroded cave walls. We refined the facial differences, using examples from caves such as Popelyushka, Mamalyha, Bukovinka, Pidzamche, as well as through the cavity that was revealed upon penetration under the collapse in the village of Dankivtsi.

Such research serves as the foundation for studying the evolution of the Miocene evaporite basin and also holds practical significance, forming the basis for investigating collapse formation in the surveyed area. This is because different facial variations of gypsum react differently to dissolution by chemically active waters.

Published: December 2024

Land resources are among the most valuable components of national wealth, and their rational use can contribute to the sustainable economic development of the state. In this regard, great hopes are placed on the development of the agricultural land market, given its potential as a tool for stimulating the agricultural sector and attracting foreign investment. Due attention and support to it will also help the flow of financial resources to local budgets, which is important for the development of infrastructure, health care, education, and social programs. Such a need seems especially urgent in the conditions of the Russian-Ukrainian war.

In the article, based on the official statistical materials of the State Service of Geodesy, Cartography and Cadastre of Ukraine and the Ministry of Finance of Ukraine, a series of thematic maps that reflect the key economic indicators of the state of the agricultural land market in Ukraine were developed and constructed. Cartographic modeling was carried out using special ArcMap software. a linear scale is taken as the most optimal. Hydrography, political-administrative boundaries, and regional centers were selected as general geographic elements. Colored cartograms and numerical signatures were used to present relevant thematic information.

Based on the analysis of thematic maps, the regional features of the dynamics of land purchase and sale transactions, losses of the agricultural land market due to full-scale invasion, weighted average prices of commercial land, and quarterly budgetary revenues of communities from the agricultural land market were noted.

The general results of the work of the land market at the first stage of its introduction (1.06.2021–1.01.2024), the influence of the Russian-Ukrainian war on its activity, and further prospects for development on the path to liberalization and deregulation of land relations are analyzed. Special attention is paid to the importance of full-fledged activity of the land market for improving the financial capacity of communities.

Despite heavy losses from Russian aggression, forced restrictions for the period of martial law (for example, the ban on the free transfer of land plots into private ownership, the closure of the public map, work with the coordinates of land plots under the control of the Security Service, etc.), Ukraine has passed the test with dignity at the first stage of agricultural land market operation. It can further develop the market with greater opportunities for agribusiness in the second stage, improve the state of the economy and people's living standards.

Constructed thematic maps can become the basis for making informed management decisions to optimize the operation of the agricultural land market of Ukraine. If necessary, other additional data can be added to the cartographic analysis.

Keywords: land market, buying and selling, cartographic modeling, thematic maps, community.

A Generalised Vision Transformer-Based Self-Supervised Model for Diagnosing and Grading Prostate Cancer Using Histological Images
Authors: Chaurasia Abadh K , Harris Helen C , Toohey Patrick W , Hewitt Alex W
Published: December 2024

BACKGROUND: Gleason grading remains the gold standard for prostate cancer histological classification and prognosis, yet its subjectivity leads to grade variability between pathologists, potentially impacting clinical decision-making. Herein, we trained and validated a generalised AI-driven system for diagnosing prostate cancer using diverse datasets from tissue microarray (TMA) core and whole slide images (WSIs) with Hematoxylin and Eosin staining.

METHODS: We analysed eight prostate cancer datasets, which included 12,711 histological images from 3,648 patients, incorporating TMA core images and WSIs. The Macenko method was used to normalise colours for consistency across diverse images. Subsequently, we trained a multi-resolution (5x, 10x, 20x, and 40x) binary classifier to identify benign and malignant tissue. We then implemented a multi-class classifier for Gleason patterns (GP) sub-categorisation from malignant tissue. Finally, the models were externally validated on 11,132 histology images from 2,176 patients to determine the International Society of Urological Pathology (ISUP) grade. Models were assessed using various classification metrics, and the agreement between the model’s predictions and the ground truth was quantified using the quadratic weighted Cohen’s Kappa (_κ_) score.

RESULTS: Our multi-resolution binary classifier demonstrated robust performance in distinguishing malignant from benign tissue with _κ_ scores of 0.967 on internal validation. The model achieved _κ_ scores ranging from 0.876 to 0.995 across four unseen testing datasets. The multi-class classifier also distinguished GP3, GP4, and GPs with an overall _κ_ score of 0.841. This model was further tested across four datasets, obtaining _κ_ scores ranging from 0.774 to 0.888. The models’ performance was compared against an independent pathologist’s annotation on an external dataset, achieving a _κ_ score of 0.752 for four classes.

CONCLUSION: The self-supervised ViT-based model effectively diagnoses and grades prostate cancer using histological images, distinguishing benign and malignant tissues and classifying malignancies by aggressiveness. External validation highlights its robustness and clinical applicability in digital pathology.

This study examines the relationships between customer service quality, employee job satisfaction, job performance, and user satisfaction in the banking industry, with a focus on Maybank. The objective is to determine how employee satisfaction and performance impact user satisfaction and customer service experience. A survey was conducted among 200 Malaysian banking customers, and responses were analyzed using regression analysis to test six hypotheses. The results confirm that customer service experience, employee job satisfaction, and job performance all significantly influence user satisfaction. Specifically, customer service experience (β = 0.291, p < 0.01) and employee job satisfaction (β = 0.322, p < 0.001) show strong positive effects on user satisfaction, while employee job performance (β = 0.200, p < 0.05) also contributes positively. Additionally, employee job satisfaction significantly enhances both job performance (β = 0.732, p < 0.01) and customer service experience (β = 0.340, p < 0.01). Employee performance is a key factor in delivering superior customer experiences (β = 0.534, p < 0.001). The study concludes that improving employee satisfaction is crucial for boosting job performance and customer service, which in turn elevates user satisfaction

Published: December 2024

This study aims to analyze the export competitiveness of processed cocoa beans from West Sulawesi Province to the Malaysian and Singaporean markets. Two analyses were conducted using the Revealed Comparative Advantage (RCA) and Export Product Dynamic (EPD) methods. The results show that processed cocoa beans from West Sulawesi Province have a strong comparative advantage in the Malaysian market but are less competitive in the Singaporean market. Key success factors include the high quality of processed cocoa beans produced, consistent supply, and supportive international import policies. Additionally, increasing export volume and the quality of raw cocoa beans is crucial to enhance competitiveness in the Singaporean market.

U.S. Approach to the Revolutions in Mexico, China and Russia: the Experience of Interaction and Reflection
Authors:   Institute of World History of the Russian Academy of Science, Manukhin Alexey
Published: December 2024

The article is devoted to the general and specific features of the practical policy of the United States in relation to revolu-tionary processes abroad in the early twentieth century. The examples used are the Mexican Revolution of 1910-1917, the Russian Revolution and Civil War of 1917-1922, the Xinhai Revolution of 1911 in China. The starting point for the study is the tradition of comparative study of revolutions, theories of their genesis and influence on international relations. It is noted that the presence of stable ideas about "progress" de-termined the positive perception of revolution as a phenome-non by Americans. Particular attention is paid to the signifi-cance of American stereotypes about their country as the most successful "revolutionary nation". A search is under-taken for evidence that the United States gradually accumulat-ed experience of interaction with revolutions, having rather limited information about them. The article examines the cor-relation of diplomatic, military, economic, and propaganda instruments of Washington's influence on the situation in Mexico, China, and Russia, identifying common and specific features. It is indicated that the Americans proceeded from the thesis of the possibility of quickly overcoming the de-structive phase of the revolution and its transition to a con-structive channel. It is assumed that the revolutions in the countries under consideration contributed to the gradual erad-ication of primitive "positivist" views on historical develop-ment in the minds of the American political elite and intelli-gentsia. At the same time, the entire architecture of planning and conducting US foreign policy was becoming more com-plex, including due to the need to compete with other "great powers." The approach outlined is intended to clarify the typ-ical features of state policy in the context of revolution as an international problem.
Global trends in the world economy and new opportunities for Russia
Authors: Ershov M. V.
Published: December 2024

Systemic changes in the global economy and in the financial markets become increasingly obvious. This is fully true for Russia. Sanctions against it are expanding, financial markets in the country are undergoing changes, even the rules of the game are changing, and the transformation of the economy is becoming increasingly clear. But despite serious challenges, in general, the forming situation opens up new opportunities for Russia. Currently, as was the case 35 years ago (when the foundations of the Russian currency market were laid, which became an indicator of subsequent market processes), conditions are once again being formed that will determine our country’s place in the global economy for years to come.
Theoretical model of macroprudential add-ons to risk-weights for foreign-currency denominated loans
Authors: Penikas H. I.
Published: December 2024

We offer a Merton-Vasicek model extension to account for the presence of foreign-currency denominated loans in the portfolio and to derive the value of the macroprudential add-ons to risk-weights in the capital adequacy ratio. We show how the add-ons depend upon the foreign-currency exchange rate volatility, and upon the ratio of foreign-currency denominated assets and liabilities of typical borrowers within such a loan portfolio. In addition, we explain why it is worth accounting for the exchange rate in the additive, and not multiplicative form in the theoretical model.

Review on Green and Efficient Synthesis of Schiff Bases and Transition Metal Complexes
Authors: Sadashiv N. Sinkar
Published: December 2024

These reviews focus on synthesizing Schiff bases and transition metal complexes using a microwave-assisted method. This method is rapid, efficient, clean and ecologically caring. The special method provides several advantages: environmental friendliness, simple work-up procedure, short reaction times, non-hazardous and excellent yields. The microwave-assisted method has become a new and rapidly growing area in man-made organic chemistry. In many cases, reactions that normally require many hours at reflux temperature under classical conditions can be completed in a microwave oven within several minutes or even seconds. Recent simplifications of microwave reaction enhancement techniques have increased microwave ovens' safety and practical utility for their use in chemical laboratories without any modification. The biological activity data show that some metal complexes are more effective than the free ligand. These compounds show different biological activities, including antifungal, antibacterial, antitubercular, antiviral, antimalarial, antidiabetic, anticancer, antioxidant, antidiuretic, anti-inflammatory, and antipyretic. This review discusses the synthesis and biological applications of Schiff bases synthesized using microwave irradiation.

Published: December 2024

In the context of rapid global economic transformation and technological advancements, the biopharmaceutical industry has seen an increasing demand for high-quality applied talent. However, traditional vocational education models have struggled to keep pace with the fast-evolving requirements of the industry. To address this challenge, this paper proposes a governance structure and sustainable development mechanism tailored to the industry-education integration community in the biopharmaceutical sector. Through the design of a multi-tier governance structure — including the strategic decision-making, operational management, and implementation layers — this study explores how to improve management efficiency and optimize resource allocation within such communities. By analyzing specific case studies in the biopharmaceutical field, this paper evaluates the role of industry-education integration in fostering technological innovation and talent development. The research shows that a scientifically sound governance structure and a well-designed sustainable development mechanism are critical to the success of industry-education integration communities. These mechanisms not only enhance the community’s capacity for innovation but also promote the deep integration of education and industry, providing essential support for the long-term development of the biopharmaceutical sector. This paper offers a theoretical foundation for future research on industry-education integration while providing practical guidelines for industry implementation.
