Published: November 2024

Accurate prediction of aqueous solubility remains a critical challenge in the chemical and pharmaceutical industries, significantly influencing drug development and delivery. This study revisits this well-explored area by leveraging the advanced capabilities of modern computational resources. We apply an automated network optimizer model that integrates dual optimization processes for molecular features and hyperparameters, streamlining the traditionally complex hyperparameter search while providing an efficient interpretation of molecular properties. By employing feature optimization techniques, our deep neural network model demonstrates improvements in both the speed and accuracy of molecular property predictions, achieving an average performance of R2 = 0.991. This result outperforms conventional hyperparameter optimization methods such as grid search and random search in predicting the intrinsic solubility of 3,745 compounds across four external experimental datasets. Based on feature importance analysis, we identified key molecular features and structures that significantly influence solubility. Additionally, combining three molecular fingerprints (Morgan, MACCS key, and Avalon) with molecular descriptors enhances model performance, providing a deeper understanding of the relationship between molecular structure and solubility within the physicochemical feature optimization process. These findings underscore the potential of machine learning models to improve predictive modeling of physical properties, apply automated modeling and feature selection to new chemical datasets, and offer explainable insights into the principles driving solubility predictions.
Testing the effectiveness of an algorithm for suppressing self-excited vibrations during intensive braking of a vehicle
Authors: Klimov A. V.
Published: November 2024

Introduction. When the vehicle slows down, particularly on slippery surfaces, stability of the electromechanical drive system movement can be reduced, which is accompanied by high self-excited vibrations. These vibrations occur when the sliding speed increases and the friction force decreases. At the same time, the dynamic load on the drive system increases sharply, which can lead to its failure. Thus, the development of methods for suppressing self-excited vibrations is an urgent task.

The purpose of the study is to test the operability and effectiveness of the method for suppressing self-excited vibrations in the electromechanical wheel drive system during braking with the use of methods of field experiments.

Materials and methods. The study of the efficiency and effectiveness of the algorithm was based on field experiments.

Results. Based on field experiment method, the efficiency and effectiveness of the algorithm for suppressing self-excited vibrations during deceleration has been determined, which allows for six-fold reduction in maximum amplitudes and 3-3,5-fold reduction in averaged amplitudes, while excluding changes in the moment sign during vehicle intense deceleration.

Conclusion. The algorithm of suppressing self-excited vibrations can be recommended for application in developing vehicle deceleration control systems

Authors: Pechatnova E. V. , Novikov I. A. , Kiryushin I. I. , Nagorny N. N.
Published: November 2024

Introduction. Accidents in cities and outside populated areas have their own characteristics, which have been studied in various works. However, changes in the characteristics of traffic, pedestrian flows, and those of the street and road environment structure usually are not observed on crossing the city boundaries. Calculations show that it is in the suburban zone that the highest accident density is estimated, as well as a high proportion of accident-hazardous areas. Besides, there has been an increase in the suburbanization process, which leads to the growth of suburban areas. In this regard, assessing the impact of various factors on accidents within the suburban boundaries is an urgent research task.

   The aim of the study is to investigate the influence of environmental factors on accidents in suburban areas (the city of Barnaul is observed as an example).

   Materials and methods. In this study the suburban zone of Barnaul was considered as an example, the boundaries of the zone being defined according to the transport methodology. The empirical basis of the work was data on accidents that were recorded for the sections of federal highways within the boundaries of the suburban zone in the period from 2018 to 2023. For each accident from the sample, the period of day and weather conditions (air temperature, precipitation rate and wind speed) were determined. The relative risk theory was used to assess the influence of the factors selected.

   Conclusions. The study identified the distinctive features of accidents in suburban areas in comparison with those of suburban and urban road conditions. The influence of the group of key external factors was also assessed: periods of the day and weather conditions. Among the former, day, civil, navigational, astronomical twilight and night periods were distinguished. As for the latter, air temperature, precipitation rate and wind speed were analyzed.

   Limitations of the study/implications for future research. The results of the study can be used in further comprehensive research of accidents in suburban areas of large cities.

   Practical implications. The identified features of accidents and the dependence of the relative risk of accidents in the suburban area on external factors can be used for preventive measures development, as well as in the development of intelligent transport systems.

   Originality. For the first time, the dependences of the relative risk of accidents in the suburban area as a result of a group of key environmental factors (period of the day and weather conditions) were determined.
The influence of mineral powders on the resistance of bitumen binder to thermal deformations

Published: November 2024

Introduction. The complex influence of dynamic loads, climatic factors, and aggressive environments is the driver of premature deformation of asphalt concrete pavements. The main types of failure are: plastic rutting deformations occurring at high temperatures above zero; fatigue cracks in the pavement caused by repeated loads; low-temperature transverse cracks occurring in the area with temperatures below zero while pavement cooling. According to modern concepts, the contribution of the binder to the formation of the described defects reaches 90–100 %. However, bitumen loses its original properties, interacting with mineral powder and forming an asphalt binder, which acts as a binder in asphalt concrete. Therefore, it is advisable to predict the behavior of asphalt concrete in a wide range of temperatures, and especially in low-temperature part, relying not on the bitumen binder, but on the asphalt binder.

   Materials and methods. Experimental laboratory studies of materials were carried out in accordance with GOST 33133–2014, GOST R 58400.1–2019, GOST 32761–2014, GOST 58401.1–2019, GOST R 58400.8–2019, GOST R 58400.11–2019. The objects of study were bitumen filled with mineral powders from limestone and dust from electric filters of an asphalt concrete plant.

   Results. Significant changes in the properties of the original bitumen were revealed under the influence of varying degrees of filling with mineral powder from limestone and dust from electric filters. It was shown that filling the binder with mineral powder (dust) in the maximum permissible concentration limit changes the PG (X) brand parameter by three positions from 64 °C to 82 °C. More fundamental data were obtained for the low-temperature stability of samples with a collapse of the parameter (± Y) from -34 °C to -22 °C. By identifying the parameters responsible for low-temperature cracking of the system at the binder level of asphalt, it is possible to scale the knowledge to asphalt concretes.
Investigating Configurations for Automated Crash Reproduction in JavaScript
Authors:   , Oliver Philip
Published: November 2024

Automated Crash Reproduction is the process of generating a test case which reproduces a software crash. The process usually identifies a crash as reproduced when a generated test can match an error with a similar execution context to the original crash, with most approaches aiming to match a stack trace. We present research outcomes which deepen the understanding of this area. The first is a reproduction study of the existing tool EvoCrash, providing insight into areas of Automated Crash Reproduction which require further research. The second is CrashJS: a benchmark dataset for Automated Crash Reproduction for NodeJS programs.

CrashJS contains 453 crashes from several pre-existing sources such as benchmarks for JavaScript bugs and security vulnerabilities, GitHub issues, and generated crashes from existing JavaScript test generation tools.

We present our changes to the SynTest-JavaScript test generation tool to leverage the existing framework for Automated Crash Reproduction. This resulted in the first tool for Automated Crash Reproduction for JavaScript programs. Our tool is the second for dynamically-typed languages, with most existing research focused on statically-typed languages. We present an empirical evaluation of fitness functions for Automated Crash Reproduction for NodeJS programs. We found fitness functions which can outperform the existing state of the art fitness functions for Automated Crash Reproduction, reproducing 18.9% more crashes from CrashJS, or 28.9% more crashes, if partial reproductions are included. Finally, we applied our fitness functions in EvoCrash to assess their suitability in Java. We found that our fitness functions could not reproduce more crashes than using the EvoCrash fitness function. However, we discovered our fitness functions could reproduce crashes faster than when using the EvoCrash function.

Influence of the main physiological groups of microorganisms on the bioavailability of 137Cs and its entry from peaty-gley soil into the biomass of Avena sativa L.
Authors: Tankevich E. A. , Nikitin A. N. , Simonchyk Yu. K.
Published: November 2024

The influence of the main physiological groups of soil microorganisms on transfer of 137Cs from the peaty-gley soil into the biomass of oats (Avena sativa L.) are analyzed in the article. The soil contaminated with radioisotopes after the Chernobyl nuclear power plant accident. The impact of these groups of microorganisms on the content of stable isotopes K, Ca, Sr, Cs in bioavailable forms in the soil are is presented as well. 1 It was established that the introduction of phosphate-mobilizing bacteria and spore-forming ammonifiers into peaty-gley soil did not change the level of 137Cs accumulation in the aboveground biomass of oats. However, both groups of soil microorganisms significantly (by 44‒84 %) increase the content of radioactive and stable isotopes of cesium in water-soluble form in the soil.

Against this background, the introduction of phosphate-mobilizing bacteria into peaty-gley soil reduces the accumulation of radionuclide in the roots of the plant by 30.5 %. The absence of increased accumulation of 137Cs in oats with increase in the content of radionuclide in water-soluble form is explained primarily by an increase in the content of К in bioavailable form in peaty-gley soil when phosphate-mobilizing bacteria and spore-forming ammonifiers are added to it.

Published: November 2024

The article analyzes the genetic diversity of populations of Lobelia dortmanna L. (Dortmann’s lobelia) performed using molecular iPBS markers. All known populations in Belarus from lakes Beloye (Luninetsky district), Svityaz (Novogrudsky district), Belyanets and Bredno (Rossonosky district), located in island localities far from the south-east border of the range, were studied. The research results showed that Nei’s greatest genetic distance is characteristic of the Belyanets population (0.15), and the least one is characteristic of the Bredno population (0.10). For this species, no relationship has been identified between the position of the population within the range, its size, plant vitality and the level of genetic diversity.

For Belarusian populations of Lobelia dortmanna L., a predominance of interpopulation variability (54 %) over intrapopulation variability (46 %) was established, which indicates a high level of their genetic differentiation. The gene flow for populations of the species under study is 0.35, which confirms the low level of gene exchange between populations and is consistent with an extremely low population size of the species in the territory of Belarus, as well as the isolation of populations both from the main fragment of the species’ range and among themselves. Data of the cluster analysis of Lobelia dortmanna L. populations demonstrate their division into 2 genetically distinct groups, the geographical location of which confirms their genetic connection with the Fennoscandian and Atlantic-European fragments of the species’ range in the northern part of Europe.
Roots of polynomials over division rings
Authors: Goutor A. G. , Tikhonov S. V.
Published: November 2024

In this article, we study the properties of polynomials over division rings. Formulas for finding roots of polynomials which are the products of linear factors are obtained. These formulas generalize the known results for quaternion algebras. As known, if a minimal polynomial of a conjugacy class A in a noncommutative division ring is quadratic, then any polynomial having two roots in A vanishes identically on A. We show that in the case of a conjugacy class with minimal polynomial of larger degree, the situation is completely different. For any conjugacy class with minimal polynomial of degree >2, we construct a quadratic polynomial with infinitely many roots in this class, but there also are infinitely many elements in this class which are not the roots of this polynomial.
Retrospective assessment of sulfur dioxide and nitrogen oxide emissions from stationary sources in Belarus
Authors: Kakareka S. V. , Krukowskaya O. Yu.
Published: November 2024

Algorithms for extrapolating series of statistical data and filling data gaps have been developed. For the first time scientifically valid estimates of sulfur dioxide and nitrogen oxide emissions from major stationary emission sources in Belarus have been obtained for the period from 1950 to 2020. Scientifically valid estimates of sulfur dioxide and nitrogen oxide emissions from major stationary sources over this period in Belarus were obtained for the first time. It was found that sulfur dioxide emissions continuously increased from 1950 to 1980 and grew almost 39 times during this period (from 22.3 to 862.4 thousand tons) attributed to increased combustion of coal, fuel oil and oil refining development. Subsequently, there was a decade of moderate emission reduction on average by 2.9 % per year. Started in 1991, there was a period of a rapid emission reduction (on average by 19.4 % per year) until reaching 80.7 thousand tons in 2000. In the subsequent period, emissions were mainly characterized by a slow decrease to an average level of 45–55 thousand tons per year. Nitrogen oxide emissions showed a rapid growth in the first three decades of the analyzed period (from 13.5 thousand tons in 1950 to 134.5 thousand tons in 1979), which is connected with an overall increase in fuel consumption. In the 1980s, there was a slow decrease up to 112.2 thousand tons in 1991, followed by more intensive reductions in the following years. In 2000, the lowest level of nitrogen oxide emissions since the mid-1960s was observed – 53.1 thousand tons. Subsequent periods were mainly marked by fluctuations in nitrogen oxide emission levels. The obtained results are significantly more accurate than the existing estimates of historical emissions within the Comprehensive Emissions Data System (CEDS).

Reasons for the existence of the utilitarian approach to literature in Russian writers – supporters of the autonomy of art’s ideas
Authors: Danilovich T. V.
Published: November 2024

The article is devoted to understanding how Russian writers, who defend the freedom and intrinsic value of art in their literary criticism (А. Fet, A. Druzhinin, N. Minsky, D. Merezhkovsky, V. Bryusov, A. Blok, Ellis, D. Burliuk, Tsvetaeva, Zamyatin, A. Voronsky, L. Lunts, V. Nabokov, N. Ulyanov, E. Kropivnitsky, A. Sinyavsky, S. Dovlatov), interpret the reasons for the utilitarian approach to literature. It is shown that the designated artists in words reveal a wide range of motives for a pragmatic view of artistic creativity. The heterogeneity of these motives is noted from the point of view of the utilitarian writer’s goal, external circumstances, object of influence, and the degree of independence in choosing the pragmatic path in literature. Specific national arguments in favor of utilitarianism considered by apologists for the idea of self­sufficiency and independence of art are highlighted. The motives of the activity of the utilitarian writers which evoke sympathy and respect among a number of representatives of Russian literature who defend the autonomy of art are outlined. The existence of such situations in public life is indicated, which supporters of freedom and the intrinsic value of art consider as conditions justifying and even making necessary the choice of a utilitarian approach to literature and literary criticism.

A Hipótese da Instabilidade Financeira de Minsky: O Ciclo de Crédito e a Crise Internacional
Authors: Barbosa Glaudionor Gomes
Published: November 2024

O artigo pretende apresentar as principais contribuições do economista norte-americano Hyman P. Minsky, em particular sua “hipótese da instabilidade financeira”. Minsky foi influenciado por muitos autores de diferentes origens, como: Oskar Lange, Henry Simons, Jacob Viner e Frank Knight. Conclui seu Doutorado em 1954 sob a orientação de Schumpeter. Começa a estudar Keynes, vindo a ser considerado como um respeitável keynesiano. A fragilidade financeira é apresentada por Minsky de acordo com o grau de prudência do endividamento das unidades econômicas que compõem um sistema financeiro. De acordo com Minsky, existem três tipos de unidades econômicas, segundo o grau de prudência do endividamento. São elas: (a) as unidades Hedge, nas quais o endividamento é tal que as entradas monetárias, oriundas dos rendimentos esperados, são mais elevadas quando comparadas às saídas monetárias em pagamento das dívidas, em cada período significativo; (b) as unidades especulativas, onde as saídas monetárias para pagamentos de dívidas são superiores às entradas monetárias almejadas em alguns curtos períodos, mas as unidades podem se refinanciar (há o risco do valor líquido do investimento tornar-se negativo); (c) as unidades de Ponzi são aquelas nas quais as saídas em pagamento dos juros da dívida são maiores do que as entradas monetárias esperadas, tornando o valor do investimento líquido negativo.

OPERA APERTA IN UKRAINE: LIBRETTO IN PERFORMANCES WITH AN OPEN SCRIPT
Authors:   P.I. Tchaikovsky National Music Academy of Ukraine, Borodina Nataliia
Published: November 2024

The purpose of the work is to investigate the possibility of preserving and reproducing the texts of modern Ukrainian experimental operas (opera aperta) with an open plot, the libretto of which changes from production to production, depending on the historical context, audience, stage and the use of interactive elements. Methodology: used textual methods and analysis of open sources (OSINT), historical-comparative method, method of analysis and synthesis. Scientific novelty. For the first time, criteria of sufficiency for the preservation of experimental operas with an open plot were developed, and methodological guidelines were provided for the processes of organizing preservation and reproduction. We improved our available knowledge about methods of deconstruction of texts in "opera aperta" performances. The study of the texts of modern experimental operas with an open plot in the traditions of post-dramatic theater has gained further development. Conclusions. The conducted analysis showed that experimental operas, despite their open character, changes from production to production, and the absence of a libretto in the traditional sense of the word, have unchanged textual elements – first of all, this is the justification of the concept of the work (which were made on the project website, in an interview mass media and on the pages of social networks), which gives the opportunity to restore the author's idea with the help of a variable substrate. In the construction of operas with an open plot, fragments of classical texts (musical and literary) and folk motifs are used, references to which make it possible to re-deconstruct according to the instructions contained in the concept.

Published: November 2024

In the modern world, the topic of employment and the creation of tools to optimize the provision of these services is very relevant. The crises of recent years (e.g., Covid-19, Russia's full-scale invasion of Ukraine) have had a significant impact on the global economy and the labor market. The rapid pace of informatization has created a situation where the labor market is overwhelmed with information about available vacancies, but at the same time needs qualified specialists. That is why the use of information systems to automate recruitment will reduce the cost of searching and selecting candidates, increase the accuracy and objectivity of decision-making, and provide centralized management of recruitment processes. The purpose of the paper is to model the operation of an information system for automating recruiting processes. Recruiting, as an important component of personnel management, has its own peculiarities and challenges. The modern labor market requires companies to be flexible, innovative and have effective strategies to attract the best specialists. The methodology of the study is based on general research methods of analysis and the basics of modeling information systems using CASE technology tools. The use of CASE technologies for modeling information systems is an important tool in the software development process. CASE technologies provide automation of various stages of the software life cycle, from requirements analysis to testing and system support. As a result of the study, to represent the static structure of the system model, a class diagram was constructed, which includes such classes as Recruiter, Candidate, Vacancy, Application, Offer; to depict the relationship between actors and precedents in the system, a use case diagram was constructed, which includes such options as “Register in the system”, “Manage vacancies”, “Log in”, “Find a vacancy”, “Find a candidate”, “View a vacancy”, “View a candidate”, “View an offer”, “View an application”; to depict the interaction between parts of the composite structure or cooperation roles, a cooperation and sequence diagram was built for the use case “Respond to an application”; to display the components, dependencies and relationships between them, a component diagram, which includes such components as MainWebServer, Database, MainSignUp, CandidateInterface, RecruiterInterface, NotificationSystem, JobApplicationManager; to display the computing nodes during the program operation, components, and objects executed on these nodes, a deployment diagram was built. Practical implications. The proposed model of the information system for automating recruiting processes can be the basis for developing the architecture of the corresponding information system and optimizing recruiting processes. The value/originality of the information system for automating the recruiting process is its versatility and can be adapted for recruiting specialists in various fields of activity.

Minimum principal stress data are essential for well design, drilling, completion, plug and abandonment, and reservoir injection planning optimization. This data can be obtained using extended leakoff tests (XLOT), which are performed after drilling a short openhole section below the casing/liner shoe. XLOT test data are only acquired just below casing/liner shoes. Least principal stress data can also be acquired using a wireline testing tool configured with the straddle packer section (SPS), which gives the flexibility to perform multiple microfrac tests at different zones of interest in a single run to obtain the minimum stress profile. The process of microfrac with a wireline tool involves setting the packers at a desired depth, inflating the packers to isolate the interval, injecting into the packed-off interval to increase the interval pressure until the rock breaks down, propagating the induced fracture by continuing injection and then shutting off the injection and observing the pressure falloff. The falloff data are analyzed to estimate the minimum principal stress. This method works in rocks with some permeability so that the fluid can naturally leak off into the formation through the fracture. Caprocks and other shales are extremely low permeability with very small to no leakoff. A recent technology development provides a flowback option at a controlled rate to remove the injected fluid from the packer interval, thereby reducing the interval pressure and enabling fracture closure. This technology was successfully applied in a well in the Norwegian Sea, where XLOT data was also acquired. Typically for XLOT, larger volumes of fluid are injected, thereby extending the induced fracture in the order of 15 m from the wellbore. In contrast to the XLOT, much smaller volumes are injected during microfrac tests, thereby extending the fracture only a short distance of the order of 1 to 3 m from the wellbore. In this paper, the results from the microfrac with wireline formation tester are compared with the conventional XLOT test. There is a good agreement in the estimated minimum stress from both measurements. The analysis of pre- and post-frac borehole electrical images to determine stress orientation is also discussed. A well where both types of tests were conducted enables a unique opportunity to compare the results provided by two different techniques measuring formation minimum principal stress. This is also the second well for the same operator in which the flowback technology was successfully used for caprock microfrac.

Mining and oil and gas enterprises use various pipeline designs and pipe fittings to transport various combustible, explosive, toxic and other hazardous media, both liquid and gaseous. To prevent emergencies leading to production downtime, harming the life and health of personnel, as well as affecting the environmental situation, modern technical means are required to detect emerging defects in a timely manner and with sufficient accuracy. The article justifies the relevance to use nondestructive testing methods in assessing the technical condition and residual life of pipelines and shut-off valves of mining and oil and gas sector enterprises. The prospects of diagnosis by the method of analysis of excited oscillations are proved. The design and algorithm of operation of the Kamerton diagnostic complex produced by the ROS Research and Production Enterprise (Perm) are described. The methodological basis of defect finding using the Kamerton multichannel analyzer are described. The main characteristics of the registered signals are listed that characterize the condition of the elements of the technical facilities based on the results of diagnostics. In terms of efficiency and timely response, the method has no analogues in comparison with traditional methods of non-destructive equipment testing, e.g. the magnetic, eddy current, ultrasonic flaw detection, ultrasonic thickness measurement, radiation, radio wave, penetrating substances control, and other methods. In some cases, for example, for the elements made of ceramics, materials of heterogeneous structure such as polymers or concrete, the proposed method is the only possible diagnostic method.

Authors:   The Korean Society of Music Education Technology, Park Eunseung
Published: November 2024

The 2022 revised curriculum was announced to help students develop core competencies required by the future society and grow into leading individuals in line with the changing times. The purpose of this study is to examine the utilization of various Edtech programs and effective teaching methods in the field of Edtech through them. We believe that what students need to live in a rapidly changing future society is self-directedness to make judgments and decisions on their own and the ability to utilize digital media, and we plan to utilize Edtech as a method to develop these abilities. In this study, we analyzed the 2022 revised music curriculum and examined teaching methods in the field of music creation using Edtech. The most noticeable change in the revised music curriculum is the establishment of a creative field, and since there are many ways to apply Edtech to the creative field, we focused on creative activities. By analyzing the revised curriculum, we organized the activity topics of creative classes, explored Edtech that can be utilized in music classes, and then presented learning strategies that can enhance self-directedness. Based on this, a teaching and learning model for the music creation field utilizing Edtech was presented and a teaching and learning guidance plan was proposed accordingly. Edtech can be utilized in various ways in music creation classes and can be said to be an essential element in education for the future. Through this study, it was confirmed that the use of Edtech in music and creation classes can foster learners' self-directed capabilities and digital media utilization capabilities. It is hoped that this study will be helpful to teachers in the field and that follow-up research on this topic will continue.
2022 Revised Music Curriculum How to learn the elements of Korean traditional music related to Hanbae
Authors:   The Korean Society of Music Education Technology, Park Jiyoung
Published: November 2024

The purpose of this paper is to present a plan to learn elements related to Hanbae among the music elements of the 2022 revised music curriculum. To this end, first, the music elements of the content system and achievement standards of the 2022 revised curriculum were examined, and the Korean traditional music elements related to Hanbae among the music elements were reviewed with prior research and literature. Second, the implementation patterns of Hanbae-related activities were analyzed in the 2015 revised music textbook and the 2022 revised 3rd-4th grade exhibition music textbook. Third, a teaching and learning plan for learning Korean traditional music elements related to Hanbae was presented. As a learning method presented in this study, it is expected that the concept of Hanbae, which students vaguely understood, can be comprehensively understood as multi-sensory activities of hearing, vision, touch, and motor sensations. In addition, it will be possible to internalize the Korean traditional music by understanding that the elements related to Hanbae, such as Hanbae's change, Ginzajin format, and Hanbae's format, are linked to each other through various activity experiences, and by discovering the characteristics of Korean traditional music elements on their own. Furthermore, it is expected that the
development of a plan to educate Korean traditional music elements such as Hanbae, Hanbae's change, Ginzajin format, and Hanbae's format, which are organically connected, is not independently learned, but rather complexly.
