FEATURES OF ELECTRON RUNAWAY IN A GAS GAP WITH A CONICAL CATHODE
Authors: Zubarev N. M. , Zubareva O. V. , Yalandin M. I.
Published: April 2024

The conditions and dynamics of electron runaway in a gas gap with an inhomogeneous distribution of the electric field due to the use of a conical cathode are analyzed. Significant differences in the behavior of electrons at cone opening angles larger and smaller than the threshold value of 98.6 degrees are revealed. For a weakly inhomogeneous field distribution (cones with angles exceeding the threshold), electrons are continuously accelerated throughout the gap. In a strongly inhomogeneous field (cones with relatively small opening angles), electrons can gain maximum energy inside the gap, and begin to decelerate in the near-anode region. Despite this, they reach the anode with high energies comparable to the work of the electric field. This difference leads to the need to use different criteria for the runaway of free electrons in the gas gap.
ON CONTACT PROBLEMS FOR TWO STAMPS AND A NEW TYPE OF CRACK MODEL
Authors: Babeshko V. A. , Evdokimova O. V. , Babeshko O. M. , Zaretskaya M. V. , Evdokimov V. S.
Published: April 2024

In this work, for the first time, an exact solution of the contact problem of interaction with a multilayer base of two semi-infinite stamps, the ends of which are parallel to each other, is constructed. Stamps are assumed to be absolutely rigid, and the distance between them can have any finite value. The task is an important stage in the algorithm for constructing models of a new type of crack in materials of different rheologies. The mechanism of destruction of the medium by cracks of a new type is radically different from the mechanism of destruction of the medium by Griffiths cracks, and has so far been poorly studied. Griffiths formed his cracks with a smooth border as a result of compression from the sides of an elliptical cavity in the plate. Cracks of a new type have a piecewise smooth border, resulting from the replacement of an ellipse with a rectangle compressed from the sides. The problem considered in the article can be considered as the result of the formation of a new type of crack with absolutely rigid banks and deformable lower boundary. Thanks to it, after the solution, it becomes possible to switch to deformable stamps and a crack of a new type in the rheological medium. The solution of this problem turned out to be possible due to the construction of exact solutions of the Wiener–Hopf integral equations on a finite segment. The paper shows how the solution of one of the previously unsolved problems allows us to investigate and solve exactly other problems, to identify previously unknown properties and resonances. As a result of constructing an exact solution to the problem, the fact that the solution of dynamic contact problems for stamp systems is not unique was confirmed and a dispersion equation for finding resonant frequencies was constructed.

DFT STUDY OF KETO-ENOL EQUILIBRIUM AND GLOBAL ELECTROPHILICITY OF HYDROXYMALEIMIDE DERIVATIVES
Authors: Panov Alexey A.
Published: April 2024

For 36 3-hydroxymaleimide derivatives energies of enol and keto forms were calculated by DFT method. The results clearly show that with only few exceptions, enol form is energetically more favourable by 16–60 kJ mol–1, with energy difference depending on 4-substituent. Global electrophilic index was calculated for all the compounds in question, showing that keto form is generally more electrophilic, with electrophilicity strongly dependending on 4-substituent. Two possible structures of hydroxymaleimide anion were evaluated, with deprotonated oxygen atom being the most energetically favourable.

Published: April 2024

For the first time, the kinetics of the process of butyl lactate production by the interaction of ammonium lactate with n-butanol in the presence of water in the temperature range of 130–170°C in a closed system was studied as one of the stages of a new complex technology for the production of lactic acid and polylactide. The flow diagram of the process has been established. For the first time, a kinetic model of ammonium lactate esterification with n-butanol was proposed, considering the side formation of lactamide and the catalysis of esterification due to the acidity of lactic acid. The developed kinetic model can be used for mathematical modeling of the butyl lactate synthesis reactor.

Authors: Musina E. I. , Strelnik I. D. , Litvinov I. A. , Karasik A. A.
Published: April 2024

The approach to the synthesis of bis-phospninesulfides and nickel and platinum chelate complexes of 1,3,6-azadiphosphacycloheptanes is supposed. The approach is based on the ability of 14-membered 1,8-diaza-3,6,10,13-tetraphosphacyclotetradecanes undergo the reversible transformation to the mixture of meso- and rac-isomers of 7-membered bisphosphines during the solution. The reaction of 1,8-diaza-3,6,10,13-tetra-phosphacyclotetradecanes with elementary sulfur results in 14-membered tetra(phosphinesulfides) or 7‑membered bis(phosphinesulfides) that depends on the reaction conditions. The reaction of 1,3,6-azadiphosphacycloheptanes, forming by the reversible dissociation of 14-membered tetraphosphines in chloroform, with Ni(CH3CN)6(BF4)2 and Pt(COD)Cl2 give corresponding chelate complexes. The structures of meso-isomer of 1-cyclohexyl-3,6-diphenyl-1-aza-3,6-diphosphacycloheptan-3,6-disulfide 8, bis-(κ2-1-isopropyl-3,6-diphenyl-1-aza-3,6-diphosphacycloheptane)nickel bis(tetrafluoroborate) 9, bis-(κ2-1-icyclohexyl-3,6-diphenyl-1-aza-3,6-diphosphacycloheptane)chloronickel tetrafluoroborate 10 and cis-dichloro-(κ2-1-cyclohexyl-3,6-diphenyl-1-aza-3,6-diphosphacycloheptane)-platinum(II) 13 were established by single crystal XRD analysis.

Published: April 2024

In this work rhodium and iridium immobilized complexes were prepared and characterized by X-ray photoelectron spectroscopy. For the first time, hyperpolarized 13C-ethylene was detected directly in the gas phase during acetylene hydrogenation with parahydrogen on immobilized iridium complexes. The line shape of polarized 13С‑ethylene unambiguously indicates that the hydrogen addition to the triple bond of acetylene on immobilized iridium complexes proceeds via syn-addition. It has been shown that the selective acetylene hydrogenation with parahydrogen over immobilized iridium complexes is an effective chemical method for enriching the nuclear spin isomers of ethylene.

ON ONE APPROACH TO THE ASSESSMENT OF A TRIANGULAR ELEMENT DEGENERATION IN A TRIANGULATION
Authors: Kriksin Yu. A. , Tishkin V. F.
Published: April 2024

A quantitative estimate of a triangular element quality is proposed - the triangle degeneration index. To apply this estimate, the simplest model triangulation is constructed, in which the coordinates of the nodes are formed as the sum of the corresponding coordinates of the nodes of some given regular grid and random increments to them. For different values of the parameters, the empirical distribution function of the triangle degeneration index is calculated, which is considered as a quantitative characteristic of the quality of triangular elements in the constructed triangulation.
NUMERICAL-STATISTICAL INVESTIGATION OF SUPEREXPONENTIAL GROWTH OF THE MEAN PARTICLE FLUX WITH MULTIPLICATION IN A HOMOGENEOUS RANDOM MEDIUM
Authors: Mikhailov G. A. , Lotova G. Z.
Published: April 2024

The new correlative-grid approximation of a homogeneous random field is introduced for the effective numerically-analytical investigation of the superexponential growth of the mean particles flux with multiplication in a random medium. A complexity of particle trajectory realization is not dependent on the correlation scale. The test computations for a critical ball with isotropic scattering showed high accuracy of the corresponding mean flux estimates. For the correlative-grid approximation the possibility of Gaussian asymptotics of the mean particles multiplication rate when the correlation scale decreases is justified.
DYNAMICS OF A SYSTEM OF TWO EQUATIONS WITH A LARGE DELAY
Authors: Kashchenko S. A. , Tolbey A. O.
Published: April 2024

The local dynamics of systems of two equations with delay is considered. The main assumption is that the delay parameter is large enough. Critical cases in the problem of the stability of the equilibrium state are highlighted and it is shown that they have infinite dimension. Methods of infinite-dimensional normalisation were used and further developed. The main result is the construction of special nonlinear boundary value problems which play the role of normal forms. Their nonlocal dynamics determines the behaviour of all solutions of the original system in а neighbourhood of the equilibrium state.

Authors: Lazareva G. G. , Oksogoeva I. P. , Sudnikov A. V.
Published: April 2024

The paper presents the results of mathematical modeling of plasma transfer in a spiral magnetic field using new experimental data obtained at the SMOLA trap created at the Budker Institute of Nuclear Physics SB RAS. Plasma confinement in the trap is carried out by transmitting a pulse from a magnetic field with helical symmetry to a rotating plasma. New mathematical model is based on a stationary plasma transfer equation in an axially symmetric formulation. The distribution of the concentration of the substance obtained by numerical simulation confirmed the confinement effect obtained in the experiment. The dependences of the integral characteristics of the substance on the depth of corrugation of the magnetic field, diffusion and plasma potential are obtained.

A NEW COURSE “ALGEBRA + COMPUTER SCIENCE”: WHAT SHOULD BE ITS OUTCOMES AND WHERE IT SHOULD START
Authors: Borovik A. V. , Kondratiev V. V
Published: April 2024

The words “Programming is the second literacy” were coined more than 40 years ago [13], but never came to life. The paper develops and details that old slogan by proposing that the mainstream mathematics education in schools should merge with education in computer science/programming. Of course, this means a deep structural reform of school mathematics education. We are not talking about adapting the 20th century mathematics to the 21st century—s it outlined in [10, 19], we mean the 21st century mathematics education for the 21st century mathematics. To the best of our knowledge, this paper is perhaps the first known attempt to start a proper feasibility study for this reform. The scope of the paper does not allow us to touch the delicate socio-political (and financial) sides of the reform, we are looking only at general curricular and didactic aspects and possible directions of the reform. In particular, we indicate approaches to development of a Domain Specifiic Language (DSL) as a basis for all programming aspects of a new course.
ADAPTIVE DOMAIN-SPECIFIC NAMED ENTITY RECOGNITION METHOD WITH LIMITED DATA
Authors: DYCHKA Ivan , POTAPOVA Kateryna , VOVK Liliya , MELIUKH Vasyl , VEDENIEIEVA Olga
Published: April 2024

The ever-evolving volume of digital information requires the development of innovative search strategies aimed at obtaining the necessary data efficiently and economically feasible. The urgency of the problem is emphasized by the growing complexity of information landscapes and the need for fast data extraction methodologies. In the field of natural language processing, named entity recognition (NER) is an essential task for extracting useful information from unstructured text input for further classification into predefined categories. Nevertheless, conventional methods frequently encounter difficulties when confronted with a limited amount of labeled data, posing challenges in real-world scenarios where obtaining substantial annotated datasets is problematic or costly. In order to address the problem of domain-specific NER with limited data, this work investigates NER techniques that can overcome these constraints by continuously learning from newly collected information on pre-trained models. Several techniques are also used for making the greatest use of the limited labeled data, such as using active learning, exploiting unlabeled data, and integrating domain knowledge. Using domain-specific datasets with different levels of annotation scarcity, the fine-tuning process of pre-trained models, such as transformer-based models (TRF) and Toc2Vec (token-to-vector) models is investigated. The results show that, in general, expanding the volume of training data enhances most models' performance for NER, particularly for models with sufficient learning ability. Depending on the model architecture and the complexity of the entity label being learned, the effect of more data on the model's performance can change. After increasing the training data by 20%, the LT2V model shows the most balanced growth in accuracy overall by 11% recognizing 73% of entities and processing speed. Meanwhile, with consistent processing speed and the greatest F1-score, the Transformer-based model (TRF) shows promise for effective learning with less data, achieving 74% successful prediction and a 7% increase in performance after expanding the training data to 81%. Our results pave the way for the creation of more resilient and efficient NER systems suited to specialized domains and further the field of domain-specific NER with sparse data. We also shed light on the relative merits of various NER models and training strategies, and offer perspectives for future research.

Authors:   ,   San Jose State University, White Tijan
Published: April 2024

This study aimed to determine the percentage of first-generation college students enrolled at California Community Colleges and examine their experiences through a culturally engaging lens using a mixed-methods approach. The research was interested in determining what percentage of community college students hold first-generation college student status using the federal definition of the term, understanding to what extent those students found their campus environments to be culturally responsive and relevant to their needs and what insights some of these students could offer regarding their experiences. The researcher surveyed and facilitated a focus group discussion with students throughout the Bay Area geographic region to assess students' perceptions and experiences. The data collected indicated that first-generation student status as defined by the federal government is more prevalent in California Community Colleges than previously reported and that, generally speaking, find their campuses more culturally engaging than their non-first-generation counterparts. However, there were only statistically significant differences between firstgeneration and non-first-generation college students concerning their perceptions of their campus' cultural relevancy as defined by the Culturally Engaging Campus Environments Model of College Success.
The influence of geometrical shape on the buckling of thin-walled axisymmetric
shells
Authors: Krivenko Olga P. , Lizunov Petro , Kalashnikov Oleksandr
Published: April 2024

The most economical for long span structures are thin-walled covering consisting
of shell elements. These include shells of cylindrical, spherical, conical and other
shapes. Buckling analysis of thinwalled structures is important in the design of
buildings and structures. In this case, the geometric shape of the shell used has a
great effect on the critical load. A comparative analysis of the geometrically nonlinear
deformation, buckling, and postbuckling behavior of rotation panels of the same v olume
under static thermomechanical loading is carried out. Spherical and conical shells
having the same thickness, rise and weight are considered. Preheated shells are loaded
with uniform external pressure. The calculation method is based on geometrically
nonlinear relations of the three-dimensional theory of thermoelasticity without the use
of simplifying hypotheses of shell theory and the use of a moment finite element scheme.
A universal 3D isoparametric finite element is used. The element allows you to model
shells of stepwise variable thickness, with breaks in the middle surface and with other
geometric features in thickness. The problem of nonlinear deformation, buckling, and
postbuckling behavior of inhomogeneous shells is solved by a combined algorithm that
employs the parameter continuation method, a modified Newton–Kantorovich method, and a
procedure for automatic correction of algorithm parameters. The method has been
justified numerically in the authors' articles. Research has revealed the behavioral
features of the compared shallow panels.

The proposed approach to the formalization of models of development projects and
the development of a higher education institution (HEI) provides the possibility of
modeling (research), processes of training future specialists and development with the
selection of points of origin of projects for the implementation of management tasks.
This makes it possible to simplify the description of the main processes of vocational
training and to build models for the analysis of improvements through the system of
quality and development in the training of specialists in vocational training. In order
to conduct higher education diagnostics and form harmonized decisions in higher
education development programs in the system of higher education, it is advisable to use
programs for the development and management of business processes, the management
functions of which are focused on the analysis of the state of the higher education
institution and management functions that ensure a successful and less expensive result
of higher education development with taking into account the increased requirements of
the external environment and the labor market. One of the conceptual provisions of the
development of information technologies and education management systems is the further
development of information provision in the formation of a single perfect information
environment, informatization of education management systems, and evaluation of the
quality and effectiveness of training specialists for the production industries, taking
into account the requirements of the labor market, production and modern development of
science. The proposed technique and method of comprehensive assessment of the quality of
education of graduates of higher education institutions with the help of IT on the basis
of indicators and indicators of quality, according to quantitative and qualitative
factors, their composition, taking into account the needs of production, the
requirements of the external and internal and educational environment. Thus, the main
technology of education quality management is the most widespread component of
artificial intelligence - fuzzy systems. Thanks to its combination with classical models
and methods of ensuring the process of management of higher education institutions, it
was possible to obtain wider opportunities for working out those parameters that until
then had not been considered due to their qualitative nature. It is advisable to include
the following input components to the main indicators: finance, training and
development, competence, satisfaction, requirements and assessment of higher education

Model development of the system for avoiding echo chambers in social networks
Authors: Stetsyk Oleksii , Terenchuk Svitlana
Published: April 2024

This article examines the problems that appear in the process of the development
of social networks. The focus of the study is on the echo chamber effect in various
social networks. It turned out that the echo chamber effect is the result of the work of
a deep neural network, which analyzes the interests and priorities of each social
network user, checks other similar posts and priorities of other users, and then forms a
“circle” of like-minded people for each user. Thus, the main drawback of the standard
content generation algorithm is the selection of only publications and comments that
support the user’s position. The goal of the study is a software architecture to solve
the echo chamber problem in highly loaded social networks in real-time. The main idea
was to cluster opinions on controversial topics and include user opinions from different
clusters in user content. Data on controversial topics is collected from news, scholarly
articles, publications, and comments with hashtags. The collected topics are clustered
usi ng the K-means algorithm and the “elbow” method is used to find the optimal number
of clusters. The result of the clustering of opinions by topic is provided as input data
for the generation of a news feed by a recurrent neural network. The system uses Kafka
as a message broker between microservices and AZURE blob storage for storing
publications and comments. Both solutions support high scalability.

Human Immunodeficiency Virus (HIV) infection, known as Acquired Immunodeficiency Syndrome (AIDS), continues to be a major global health issue, impacting millions worldwide. The disease progresses through the depletion of CD4+ T lymphocytes, compromising the immune system's capacity to fight opportunistic infections and cancers, leading to high morbidity and mortality without treatment. The socioeconomic impact of HIV/AIDS is profound, exacerbating poverty and inequality, especially in under-resourced regions. Standard HIV/AIDS management includes antiretroviral therapy (ART), prophylaxis against opportunistic infections, and supportive care, with ART regimens comprising various drug classes such as nucleoside and non-nucleoside reverse transcriptase inhibitors, protease inhibitors, integrase inhibitors, and entry inhibitors. These therapies have transformed HIV into a manageable chronic condition, yet access to these treatments remains unequal globally. This perspective traditional approaches to HIV therapy, the socioeconomic impacts of the disease, and the potential of innovative treatments like hypochlorous acid (HOCl). HOCl is a naturally occurring antimicrobial agent produced by neutrophils, effective against a broad spectrum of pathogens through mechanisms of oxidative damage and immune modulation. Given its antiviral properties, especially in the context of early innate immune responses, this review explores the feasibility of HOCl as a novel therapeutic avenue in HIV/AIDS management, aiming to broaden the current treatment landscape and address ongoing challenges in global HIV care.
An Approach to Robust Fatigue Life Prediction to Be Used in Early Design Stages
Authors: Cronemyr Peter , Eriksson Robert
Published: April 2024

Many engineering structures eventually fail through fatigue. Design against fatigue is one of the more important parts of the engineering design process in order to avoid injuries/fatalities, improve sustainability and decrease costs. Design against fatigue is often a complicated and time-consuming process. New, faster, and sufficiently accurate engineering tools are much needed to allow for quick computational estimates as well as robust and risk-minimized engineering solutions. By combining knowledge from the fields of solid mechanics and quality management, such a tool has been developed and is proposed in this paper. By combining easy-to-use tools for robust design and probability design with engineering tools for stress analysis and fatigue analysis, regression equations and response surfaces can be developed to be used for choosing a robust solution. Hence reducing the sensitivity to variation in loads, material characteristics and other noise factors. After a design has been selected, a more detailed analysis can be carried out to validate the solution. Preliminary results from an application of analysis and design of an airplane wheel axle are presented.

The emergence of social media and its development makes it easier for individuals to carry out various interactions. Social Media plays a role as an effort to improve the quality of public services. Social media is a more efficient means of building relationships between government agencies and the community. One of them can lead to achieving understanding between the community and government agencies because this is an effort to improve the quality of public services. One of the efforts made by the Sidoarjo Dukcapil Department to improve the quality of public services is by optimizing Instagram social media. Optimizing Instagram in government agencies is something that needs attention, both in sharing information and activity content. Therefore, this research aims to find out how to optimize the Sidoarjo Disdukcapil Instagram social media as an effort to improve the quality of public services based on the 4C concept and The Circular Model of Some for Social Communication, using a qualitative descriptive approach. The results of this research show that the Sidoarjo Disdukcapil Instagram social media optimization as an effort to improve the quality of public services still does not fully fulfill the dimensions contained in the theory of social media utilization, namely Context, Communication, Collaboration, and Connection. This is because a conducive communication space has not been created and social media managers have not responded to all responses from the public, besides that the collaboration carried out has not been extensive. So there are still many dimensions that still need to be improved.

Transfer pricing reforms in the context of BEPS: challenges remain
Authors: Pyroha S. S.
Published: April 2024

The presence of affiliated entities in different countries and the independence of tax systems make it easy to shift profits from jurisdictions with high corporate tax rates to jurisdictions with low rates. Transfer prices and the arm's length principle are used to prevent profit shifting. The article identifies the peculiarities of transfer pricing reform in the context of the BEPS plan, analyses changes to Ukrainian legislation and opportunities for its improvement. The article analyses the amendments to the Tax Code of Ukraine aimed at ensuring the implementation of the BEPS plan. The shortcomings of these amendments are outlined and amendments are proposed to improve the legislation. The author also examines the compliance with the BEPS guiding principle, which provides for the taxation of profits where profit-generating economic activities are carried out and where value is created. It is established that the amendments to the Tax Code of Ukraine do not ensure the implementation of this principle. In addition to the problems of practical implementation of the provisions of legislation, the article identifies conceptual shortcomings of the proposed improvements to the transfer pricing methods, which practically do not ensure the achievement of the set goals. An alternative method of pricing based on the market assessment of value added, which is determined by the sum of the firm’s factor income, wages and profits, is substantiated. Instead of the concept of “transfer price”, the concept of “fair market price” is introduced, which is determined by the sum of value added, depreciation and expenses, representing the added value of all previous stages of the production and/or distribution cycles. The proposed approach excludes the concepts of “affiliated entities”, “transfer prices” and “arm’s length principle”. The existence of a unified system of value added tax in the European Union allows for the unification of the tax system in terms of direct and indirect taxes as a result of the introduction of fair market prices. Amendments to the legislation have been proposed to allow for automatic solution of the following tasks.

The research deals with assessment of business ethical aspects for such international companies as Starbucks and Ueshima Coffee Company (UCC), which is relevant in the context of the global business community's focus on achieving the sustainable development indicators of the Agenda 2030 and digital business transformations, which correlate with new ethical challenges associated with ensuring fairness, transparency, privacy, security and accountability in the implementation of digital technologies. We defined the notion of business ethics, its main elements and relations to other categories. Also, cause-effect links were established between cultural features of the USA and Japan and their business ethical aspects. In particular, we focused on certain social basic values: how they influence the business readiness to accept ethical norms. Besides, we estimated the efficiency of corporate social responsibility (CSR) for Starbucks and Ueshima Coffee Company. Their ethical awareness is quite high with minor violations as to five parameters. For example, the Starbucks unethical behavior is confirmed by no open-access data on employees’ CSR training, low progress in environment protection (coffee cup recycling, carbon dioxide decreasing). On the other hand, there is no person to check the CSR observance while reports on social-ecological indexes are not complete. Simultaneously, the Ueshima Coffee Company does not provide any open reports with financial and social-ecological data. No documents of anti-corruption policy are available. Moreover, the social inequality fall is not included unto the Ueshima Coffee Company agenda. Finally, we defined recommendations to improve the corporate ethics and to standardize business ethical principles.
