Authors: Dubey Vaidehi , Prakash Sant
Published: February 2025

Antigone antigone (Linnaeus, 1758), commonly known as Sarus Crane is a widely distributed water bird that is found in India, Australia, and Southeastern parts of Asia. It is divided into three extant subspecies, but its number has been on a decline in recent years. In this study, a non-invasive approach was applied for obtaining the genomic DNA from the molted feathers extracted from Sarsai Nawar Wetland, Etawah, Uttar Pradesh. The genetic diversity was evaluated from the 429 bp long mitochondrial DNA cytochrome b as a genetic marker was sequenced and evaluated for its genetic diversity. Hap2, encompassing sequences from India and Australia, emerged as the most prevalent haplotype in the sample. The degree of genetic difference between the subspecies exhibited a FST value of 0.391. The entire sample of Sarus Cranes had a low number of cyt b haplotypes, but the subspecies still had a high degree of genetic diversity. Negative, non-significant values for Tajima’s D (-1.660) indicate neutral evolution of populations of the three subspecies.

Російсько-українська війна як чинник переформатування постбіполярної міжнародної системи
Authors: Федуняк Сергій
Published: February 2025

У статті аналізується вплив російсько-української війни на процеси, що відбуваються в постбіполярній системі міжнародних відносин, зокрема, характер і особливості системи міжнародних відносин, що сформувалася після завершення холодної війни та основні процеси у ній, а також взаємовплив російсько-української війни та процесів трансформації міжнародної системи. Після завершення «холодної війни» система міжнародних відносин сформувалася у вигляді моделі гегемонічної багатополярної стабільності при відсутності, з одного боку, договірної бази, яка б відображала нову конфігурацію сил, а також політичної волі західних еліт до підтримання миру і стабільності на основі ліберальних цінностей. Наслідком цього стало зростання реваншистських настроїв у правлячого класу РФ, що зрештою вилилося у повномасштабну військову агресію в Україні. Російсько-українська війна справляє вплив на всі структурні виміри міжнародної системи: конфігурацію співвідношення сил, ієрархію акторів, ступінь гомогенності/гетерогенності та внутрішній режим. Одним із вагомих і помітних наслідків впливу повномасштабного вторгнення Російської Федерації на конфігурацію співвідношення сил стали консолідація і більш чітке самовизначення держав на користь того чи іншого центру сили, що призводить до зміни силових потенціалів внаслідок перерозподілу ресурсів. Російсько-українська війна не справляє прямого і безпосереднього впливу на ієрархію акторів у міжнародній системі, оскільки зміни в ієрархії є наслідком сукупності більш вагомих і багатопланових процесів. Водночас вона створила поле для підтвердження і зміцнення статусу провідних держав. Ще одним наслідком впливу війни на міжнародну систему стало зростання ступеня гетерогенності і, до певної міри, наростання ідеологічної конфронтації на рівні цивілізацій. Також війна нанесла потужний удар по внутрішньому режиму системи, зробивши його ще менш стійким і надійним. Все це призвело до різноспрямованого впливу на систему міжнародних відносин. З одного боку, фактично завершила своє існування слабка і нестабільна пост-біполярна модель, що посилило рівень загроз і викликів глобальній та регіональній безпеці. З іншого боку – розпочався процес створення нової моделі на основі нового балансу сил та інтересів провідних світових акторів.

Місцевий референдум в Україні: демократія vs. маніпулювання (case study Чернівецької громади)
Authors: Юрійчук Євгенія , Гринишин Єгор
Published: February 2025

У статті розглянуто інститут місцевого референдуму як ефективний інструмент безпосередньої демократії у місцевому самоврядуванні, покликаний вирішувати проблемні питання територіальної громади, формувати референдну культуру виборців та надавати легітимність ухваленим рішенням. Референдну легітимацію прийнятих рішень проаналізовано через довіру до результату голосування та електоральну участь. У Чернівецькій громаді референдуми використовували, здебільшого, як демократичні інструменти ухвалення рішень шляхом опитування думки населення, хоча й траплялися випадки блокування його ініціювання, маніпулювання громадською думкою для забезпечення явки виборців за допомогою використання технології паралелей, технології усунення супротивників, як інструменту перешкоджання діяльності громадянського суспільства щодо висловлення недовіри місцевій раді. Констатовано, що в Україні тільки розпочинає формуватися місцева референдна культура, яка потребує детальнішого ознайомлення населення з можливостями цього інституту, популяризації місцевого референдуму та проведення інформаційних кампаній щодо його ефективності.

New Formats of International Cooperation of Ukraine: British-Polish-Ukrainian Trilateral Pact
Authors: Kolos Dmytro Mykola
Published: February 2025

The events of the Euromaidan and Russia's aggressive actions against Ukraine became catalysts for fundamental changes not only in Europe, but also at the global level, which prompts Ukraine to activate new types of geopolitical cooperation. The purpose of the study is to identify and assess the features and prospects of the new format of international cooperation between the United Kingdom, Poland, and Ukraine – the Trilateral Pact – considering the threat posed by Russia to the region and the international security system. The tasks of the research are the analysis of the reasons for the formation of this alliance; identification of the goals imposed on it by the member states; search for strengths and weaknesses of this alliance; forecasting the prospects of the Trilateral Pact. In this research were used such research methods as: level analysis, assessment of factors at the domestic, individual, bilateral, and international levels; content analysis of documents, surveys, interviews; and factor analysis to identify determinants affecting the functionality of the Trilateral Pact. The hypothesis of this study is the statement that the United Kingdom, Poland and Ukraine will intensify cooperation within the framework of the Trilateral Pact in the future, which is facilitated by the growth of threats from the side of the Russian Federation in Europe and the international system in general, as well as the need to increase the defense capabilities of these states and the need to encourage the EU and NATO to review their positions on international security and stability. The formed hypothesis was partially confirmed, considering the fact that the functionality and effectiveness of the Triangle is influenced by the internal political and social situation in the member states of the Pact; the absence of a “road map” and a clearly formed institutional structure of the Triangle; the course of events in the Ukrainian-Russian war, as well as the level of support from the side of the USA and NATO. The deepening of geopolitical rapprochement between Poland, Ukraine and the United Kingdom will continue in the future, but with different dynamics.

Authors: Bartko Vasyl , Qian Jing , Khomenko Oleksandr
Published: February 2025

The article reflects significant changes in the way projects are managed, emphasizing the importance of integrating digital technologies to improve the efficiency and transparency of construction processes. The digital ecosystem of a construction project combines various innovative tools such as Building Information Modeling (BIM), Internet of Things (IoT), Artificial Intelligence (AI), Cloud Computing and Big Data to create an integrated environment that promotes process optimization and productivity.The basis of the transformation is the concept of ecosystem interaction, where the construction project is considered as part of a dynamic network that includes various participants: architects, engineers, contractors, suppliers and customers. Interaction between them is carried out through digital platforms, which allows coordination of actions in real time and provides access to relevant information for all interested parties. Using BIM as a central tool of the digital ecosystem allows for the integration of data on all stages of the project — from design to completion of construction and operation. This significantly reduces the time and resources spent on correcting errors, increases the accuracy and quality of work.The theoretical foundations of digital transformation include such aspects as adaptability and flexibility, which allow you to quickly respond to changes in market conditions and customer needs. The digital ecosystem allows you to automate many routine processes, increase the level of control over costs and deadlines. In addition, the use of big data analytics and AI-based forecasting helps to identify risks in the early stages and eliminate them in a timely manner, which reduces the overall risks of the project.

The handling of corruption cases in Indonesia faces various challenges, particularly concerning procedural law and political influence. This study examines how legal processes and political dynamics impact the effectiveness of corruption eradication. The central research question explores the extent to which procedural law regulations and political interventions shape law enforcement outcomes. This study aims to analyze the effects of political interference, law enforcement institutions' independence, and procedural law weaknesses on corruption case handling. This research evaluates relevant legal frameworks and case studies using a qualitative approach that combines normative and empirical legal analysis. The findings reveal that political intervention often undermines law enforcement, while gaps in procedural law create significant obstacles to effective corruption eradication. However, a strong synergy between robust legal policies and genuine political will is essential for enhancing the effectiveness of law enforcement against corruption. The implications of this study underscore the need for legal reforms and institutional safeguards to ensure impartial and effective handling of corruption cases in Indonesia.

The object of the research is the process of detecting anomalies in high-load complex computer systems (HLCSS). The practical application area includes HLCSS such as banking transaction servers and cloud platforms, where stable operation must be ensured under heavy request loads. The problem addressed in the research is the lack of real-time anomaly detection models in HLCSS with a specified accuracy under resource constraints. Anomalies may signal system malfunctions, process mismatches, or potential cyberattacks. High-load systems are particularly sensitive to even minor disruptions, as they can cause significant delays or complete service unavailability for many users simultaneously, leading to financial losses and loss of customer trust.
Modern web services face issues such as attempts of DDoS attacks, significant fluctuations in user requests, database connection problems, memory leaks, and the impact of unexpected changes in network or hardware configuration. Therefore, ensuring timely anomaly detection is a critical aspect of high-load system security. Automating the analysis process and promptly identifying potential problems in real time help reduce risks and minimize downtime. Developing a mathematical model for anomaly detection in high-load web services aims not only to improve detection accuracy but also to ensure a timely response to potential threats under resource constraints. This helps avoid significant financial losses and enhances user trust in such services.
The paper creates and investigates a mathematical model for detecting anomalous connections between components of a complex computer system (HLCSS). The testing results of the model showed the following performance metrics: accuracy – 84%, precision – 87%, recall – 74%, F1-Score – 78%. The positive results of the study are explained by the following prerequisites: the HLCSS model uses projection matrices and orthogonal vector functions for anomaly analysis. This allows for the creation of spatial decompositions that reveal complex interconnections between components of a complex computer system using only eigenvalues and vectors. Thus, the model can be applied for operational data analysis and anomaly detection in resource-constrained environments.

Published: February 2025

In modern mechanical engineering, Model-Based Systems Engineering (MBSE) has become widely adopted. One of its key concepts is the creation and testing of virtual models of the designed technical systems. Compared to traditional approaches, this method significantly reduces resources and development time for new machines or improvements to existing ones. However, the accuracy of modeling entirely depends on the precision of the input data used for simulation. This also applies to the process of feed material destruction, particularly corn kernels. To obtain reliable simulation results, it is necessary to create a model of a kernel that closely resembles the real one and assign it physical and mechanical parameters that most accurately correspond to the studied sample.
The aim of this research is to create an adequate virtual model of a corn kernel in the Simcenter STAR-CCM+ environment by comparing the destruction force obtained virtually and in laboratory experiments. Based on measurements and a review of studies in the Simcenter STAR-CCM+ software, a discrete element model (DEM) was developed using the aggregation of 86 spheres, employing the Hertz-Mindlin contact model. A virtual full-factorial experiment was conducted, resulting in regression equations describing the dependence of the kernel destruction force on Poisson’s ratio (µp), Young’s modulus (Ep), and ultimate tensile and shear stress (Wp) under different loading directions.
A laboratory test stand was developed and implemented, where experimental studies of the destruction force of corn kernels were conducted under conditions analogous to the virtual experiment. The comparison of results identified factor values at which the model matches the laboratory research findings: Young’s modulus Ep = 10 MPa, Poisson’s ratio µp = 0.48, and ultimate tensile and shear stress Wp = 2.4 MPa. The obtained results allow for refining the input parameters in corn kernel simulations, ensuring more accurate virtual studies of the destruction process under various interactions with working elements.

The article provides an in-depth analysis of a method to improve the reliability and efficiency of automated production lines by reducing maintenance costs and minimizing downtime using artificial intelligence algorithms. The method involves the application of acoustic spectra generated by the production line nodes during operation to establish a correlation with the reliability and efficiency of these lines. A model for representing acoustic spectra as a two-dimensional data array, which captures the change in acoustic spectra over time, has been proposed. The format of acoustic spectra as two-dimensional data is used to recognize equipment operation patterns. To recognize these patterns, the use of a convolutional neural network is proposed, and its software model has been developed, allowing simulation and assessment of the accuracy of using machine learning methods.
Additionally, the article highlights the results of the functioning of the developed neural network, which indicate a significant correlation between the measured acoustic spectra of the production line equipment and its reliability and efficiency indicators. The importance of this approach lies in the ability to timely detect potential problems and quickly eliminate them, which in turn contributes to reducing maintenance costs and increasing productivity.
Moreover, the implementation of this method can significantly impact the overall efficiency of production processes, providing more accurate and reliable monitoring of equipment conditions. Further research may be directed towards improving the proposed models and algorithms, as well as developing new approaches to the analysis and interpretation of acoustic spectra.
Furthermore, the integration of such advanced technologies into the production environment demonstrates a progressive shift towards more intelligent and autonomous manufacturing systems. These advancements not only enhance the performance and sustainability of industrial operations but also pave the way for future innovations. By continually refining the models and algorithms used in acoustic spectrum analysis, industries can achieve higher levels of precision in fault detection and maintenance planning. This proactive approach ensures that equipment operates at optimal levels, thereby extending its lifespan and reducing unexpected downtime. Overall, the adoption of AI-driven methodologies in industrial settings represents a significant leap forward in modernizing production lines and achieving unprecedented levels of operational excellence.

For normal operation of mechanisms and machines using various working fluids, the size of mechanical particles in it must be smaller than the gap in the moving pairs or the holes in the nozzles. In this regard, the working fluids are pre-filtered. Usually, two-stage filtration is used: first, coarse cleaning, and then fine cleaning. This work is devoted to improving the coarse cleaning system.
There are known coarse cleaning filters in which the liquid is cleaned due to sludge. They are large-volume tanks with partitions. This circumstance sharply limits the scope of use of these filters. Mesh filters are of certain practical interest for coarse cleaning of working fluids, as they are more compact and convenient to use. For coarse cleaning of working fluids, only square-weave metal meshes are used, that is, metal meshes with a square mesh. To form a cylindrical working surface of the filter element, the flat metal mesh is not only bent, but also its ends are connected using additional parts or soldering. This increases the cost of manufacturing the filter element. In addition, to increase the productivity of the liquid pumped through the filter, the need to increase the area of the filter element can significantly increase the dimensions of the filter. The latter limits the scope of its use. As we can see, all the imperfections of this coarse filter are associated with the fact that its filter element has only one working surface (cylindrical). Therefore, further improvement of the filter is aimed at developing a filter element with an additional working surface.
The purpose of the study is to reduce the cost of manufacturing and expand the scope of use of the filter.
In the proposed new coarse liquid filter, the filter element is made of a flat metal mesh with a square mesh by the method of cold multi-operation drawing. Of all known metal meshes, only meshes with a square mesh are subject to this type of deformation, i.e. do not tear. After stretching, the filter element takes the form of a cylindrical cup with a small flange, which is used for fastening. An original technology for stretching a filter element from a square blank is proposed. This filter element, compared to the known one, has not only a side, but also a bottom working surface. The filter element is tightly put on a perforated support, which does not allow the mesh to bend under the pressure of the liquid being cleaned. The use of this filter allows you to reduce the cost of its manufacture by simplifying the technology for manufacturing the filter element, as well as expand the area of use of the filter due to the presence of not only a side, but also a bottom working surface in the filter element. The latter increases its throughput and makes it more compact.

The article investigates the influence of modifying impurities such as niobium carbides (NbC), zirconium oxides (ZrO2), graphite and others on the microstructure, mechanical, corrosion and tribological properties of the deposited layers obtained by the electroslag method. The main objective of the study is to improve the performance of the working bodies of agricultural implements, such as ploughshares and cultivator tines, by applying special deposited layers. The paper discusses the influence of different types of modifying additives on microstructural changes and properties of the deposited layers, and evaluates the effectiveness of using such layers for the restoration of agricultural parts.
The use of niobium carbides and zirconium oxides can significantly increase the hardness and wear resistance of the deposited layers due to the formation of a stable microstructure with hard inclusions, which provides increased resistance to abrasive wear. Graphite, in turn, reduces the coefficient of friction, which reduces energy costs during operation and improves the efficiency of the restored parts. The article also presents the results of metallographic studies, microhardness measurements, corrosion and tribological tests, which confirm the effectiveness of using modifying additives to improve the properties of the deposited layers.
In addition to the experimental studies, a mathematical model was developed to predict the wear of the deposited layers. The model takes into account such parameters as microstructure, mechanical properties and operating conditions, which allows us to predict wear resistance and optimise the composition of deposited materials to ensure maximum service life of parts. The modelling results show high prediction accuracy, which is confirmed by experimental data.
The article also presents the results of field tests, which showed that the use of modified welded layers on ploughshares and cultivator tines can increase their service life by 25-30% compared to unmodified (factory) samples. This leads to a reduction in maintenance costs and an increase in the economic efficiency of agricultural production. An economic analysis has been carried out, which shows a reduction in the cost of maintenance and repair of equipment due to the use of linings with improved properties.
Thus, the results of the study show that the application of the electroslag surfacing method with the use of modifying additives is a promising approach to restore agricultural working bodies, increase their wear resistance and reduce operating costs. The proposed materials and methods can be used to increase the efficiency of maintenance and reduce the cost of replacing parts in the agricultural sector.
