Cyclotomic Generating Functions
Authors: Billey Sara , Swanson Joshua
Published: October 2024

It is a remarkable fact that for many statistics on finite sets of combinatorial objects, the roots of the corresponding generating function are each either a complex root of unity or zero. These and related polynomials have been studied for many years by a variety of authors from the fields of combinatorics, representation theory, probability, number theory, and commutative algebra. We call such polynomials cyclotomic generating functions (CGFs). With Konvalinka, we have studied the support and asymptotic distribution of the coefficients of several families of CGFs arising from tableau and forest combinatorics. In this paper, we survey general CGFs from algebraic, analytic, and asymptotic perspectives. We review some of the many known examples of CGFs in combinatorial representation theory; describe their coefficients, moments, cumulants, and characteristic functions; and give a variety of necessary and sufficient conditions for their existence arising from probability, commutative algebra, and invariant theory. As a sample result, we show that CGFs are "generically" asymptotically normal, generalizing a result of Diaconis on $q$-binomial coefficients using work of Hwang-Zacharovas. We include several open problems concerning CGFs.

Hydraulic hammer and dynamic loads in multiphase pipelines
Authors:   Azerbaijan State University Oil and Industry, Ismayilova F.B. , Shukurlu M.F. ,   Azerbaijan State University Oil and Industry
Published: October 2024

In oil and gas production and from the practice of transporting hydrocarbons, it is well known that, when a mono- or multiphase flow is instantly pumped, a sharp change in pressure occurs in the pipeline. As a result of hydraulic hammer, i.e., when pressure waves form and are distributed in the pipeline, compression of the pumped system and elastic deformation of the pipeline occur. Increasing the efficiency of pipeline operation requires the necessary diagnostics and consideration of the influence of such factors. The article discusses the issues of analyzing various dynamic loads in pipelines, taking into account the influence of structural forms and phase features of pumped multiphase systems.

Published: October 2024

In the article, the tension caused by the effect of permanent and temporary loads on the beam (I60) was calculated. During the calculations, the maximum bending moment generated in the beam as a result of the effect of permanent and temporary loads on the overpass beam was determined. Based on the calculated value of the bending moment, the design stress and actual stress values of the beam were calculated. When calculating the actual stress value of the beam, the values obtained based on the thickness measurement were used. In the course of calculations, along with the analytical method, reports were made with software and the results were analyzed. A three-dimensional model of the pier-platform was constructed with the help of software method, and the effects of permanent and temporary loads were applied to the beam.
Diagnostics of cavitation flows
Authors:   Azerbaijan State University of Oil and Industry, Shukurlu M.F.
Published: October 2024

The operational experience of well pipelines shows that due to the multicomponent and multiphasic nature of the well products, mixing and dilution of oils, the occurrence of cases such as narrowing and blocking of pipelines is widespread as a result of various sedimentation processes occurring in pipelines. The frequent occurrence of cavitation phenomena in pipelines because of the local resistances created in cases of narrowing greatly reduces their reliability and service life. In the article, the cavitation events caused by the narrowing of the pipelines were investigated and the diagnosis of the critical parameters of cavitation was given.
Graphoanalytical method for determining plasticity properties for structural materials
Authors:   Azerbaijan State Oil and Industry University, Musavi S.A.
Published: October 2024

The presented article sets the task of assessing and determining the plasticity of materials for the manufacture of elements of SOFC structures, manufactured on the basis of bodies in a complex stress state. To obtain estimated values of the plasticity of materials, a linear call of hardening of a deformable body is considered. As a result of the hypothesis about the strengthening of materials due to the reduction of pores, it was established that the plasticity coefficient of elastic-plastic bodies depends on its elastic parameters, porosity and deformation angles and does not depend on the factor of brittle fracture under load. A graphic-analytical method has been proposed for determining the plasticity coefficient of materials and therefore it uses all parameters explicitly to evaluate the properties of all groups of materials, including materials for SOFC.

Authors:   Azerbaijan State Oil and Industry University, Sadigova S.S.
Published: October 2024

Analysis of the enterprise’s production and economic activity, its evaluation is impossible without decision-making. There are controlling, controlled and feedback elements of management. It is in the feedback section that information is collected for making management decisions. There are numerous studies on decision-making and the tools used during it. It is known that management decisions are made at the individual and organizational level, and E. Mayo addressed the problem of optimal selection of management decisions for the first time. Decision-making in management, selection of alternative options and implementation of these decisions is a cyclical action. Since the subsystems of management are the ones that manage and are managed, there is also a need for feedback here. In management, by transferring the database to the managed subsystem, that information is processed, and in addition to the known information, environmental information that has not been taken into account affects the stability of the managed system. During the solution of the problem, more optimal decisions are made by using the possibilities of feedback in decision-making. At this time, mutual comparison of the obtained results and the selection of the most optimal of them takes place, which makes it possible to use the decisions made more effectively in experimental activities. There are many principles and approaches to decision-making in the economic literature. In the presented article, these approaches have been discussed, the author’s views have been expressed and directions for using these tools have been shown.
Нейрофизиологические механизмы двойных задач (обзор)

Published: October 2024

This review considers articles studying neural mechanisms of dual (cognitive-motor) tasks in healthy young and older people using electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS). A bibliometric network is presented showing the frequency of keywords (postural balance, gait, walking, neuropsychological tests, attention) used in publications and the associations between these keywords, as well as demonstrating the relevance of applying the cognitive-motor paradigm as a method for studying the neurophysiological mechanisms of dual-tasking. The design of the cognitive-motor dual-task paradigm used in the works varied greatly. The cognitive tasks included various computational-logical, spatial-figurative, auditory and verbal tasks as well as a modified version of a smartphone game. As motor tasks, static (stand, tandem stand) and dynamic (stand on a dynamic platform, treadmill walking, walking under the actual conditions of outside environment) tasks were used. Spatial and frequency distribution of brain activation when performing various types of cognitive and motor tasks was considered. Frontal cortical haemodynamic correlates of dual-tasking were demonstrated. Possible interpretations of research results proposed by the authors of the articles under study were indicated. The conclusions demonstrate that the actual set of tasks used in the experiment plays an essential role in the way the dual task will be processed. Dual-tasking involves activating executive functions that coordinate information processing in each task (cognitive or motor). The dual-task paradigm can be used as a model to investigate and evaluate executive functions, attention, working memory and postural control.

Over the last decades, the dietary pattern of the population has undergone changes, including a significant increase in the consumption of high-calorie food. The purpose of this study was to investigate the activity of antioxidant enzymes in rats with and without genetic predisposition to cardiovascular disease eating a high-calorie diet. Materials and мethods. Wistar (n = 30) and SHR rats (n = 30; predisposed to cardiovascular disease) were used. Animals of both strains were subdivided into two groups: control (basic diet) and experimental (high-calorie diet). Parameters of carbohydrate and lipid metabolism were determined using a biochemistry analyser; haematological analysis was performed in order to establish the type of nonspecific adaptive response of the body. The state of the antioxidant system was evaluated using the animals’ blood serum and liver homogenate by determining catalase, superoxide dismutase and glutathione peroxidase activity. Results. High-calorie diet led to excessive body weight, changes in lipid profile, impaired glucose tolerance and inadequate adaptive response of the functional systems (manifested in the strain on the adaptive mechanisms and maladaptation) as well as to depletion of antioxidant enzymes in rats of both experimental groups. The parameters of animals with and without genetic predisposition to cardiovascular disease were found to be virtually identical. Despite the fact that genetic factors contribute significantly to the development of metabolic pathologies, the results obtained in the group of Wistar rats confirm that excessive caloric intake is one of the major causes of metabolic disorders.

Physical load often varies in the course of one’s sports activity, which entails constant multidirectional changes in physiological parameters. The purpose of this paper was to study the kinetics of the chronotropic and inotropic responses of the heart to a gradually increasing load in amateur and professional runners. Materials and methods. Male amateur (n = 25) and professional long- and middle-distance runners (n = 29) with the sports ranks from Candidate for Master of Sport to International Master of Sport were examined. The protocol consisted of an exercise test with a gradually increasing load to failure on a Cosmos Quasar treadmill (Quasar Med, Germany); during the first 2 minutes, the speed gradually increased from 0 to 7 km/h, thereafter, it was gradually increasing by 1 km/h per minute. The treadmill’s angle of inclination was 1° throughout the test. Using the Metalyzer 3B software (Cortex, Germany) algorithms, haemodynamic parameters were calculated: cardiac output, stroke volume, and heart rate. Results. In both groups, stroke volume stops increasing by the 4th minute (running speed 9 km/h); during this process, amateurs’ heart rate is higher (133 ± 24 beats/min) than that of professionals (123 ± 24 beats/min; p < 0.05). No differences in the kinetics of chrono- and inotropic responses of the heart to a gradually increasing load were observed between the groups. Thus, the load that was used during the exercise test leads to the same kinetics of chronotropic and inotropic responses of the heart to a gradually increasing physical load irrespective of the subjects’ training level.

The article discusses an episode from the biography of a famous White agent in the Red army, Major General A.L. Nosovich (1878–1968), after his escape from Soviet Russia to the Whites. Nosovich served in the Red Army as chief of staff of the North Caucasus Military District in Tsaritsyn and later as assistant commander of the Southern Front. In August 1918, he was briefly arrested, but managed to prove his innocence to the Soviet command. In October 1918, having exhausted all the possibilities for continued underground activity, he crossed the front lines to join the Don Cossacks. Nosovich hoped to get recognition for his underground work, but faced mistrust and repression from the Don command. He was initially arrested, but later released and joined the Volunteer Army, where he was met with suspicion as well. In order to prove his loyalty to the Whites, Nosovich collected evidence of his service. Correspondence on these issues has survived and is presented in the article. These documents not only shed light on the specific episode in Nosovich’s life, but also in general characterize the policy of the Whites towards their supporters in the Red Army, defectors and prisoners from among former officers of the old army. This policy, lacking pragmatism, was one of the reasons behind the defeat of the White movement. In addition, the materials on the rehabilitation of General Nosovich by the Whites provide new details on the work of anti-Bolshevik underground organizations in Soviet Russia in 1918. This research complements the previously published collection of Nosovich’s documents, which include his memoirs and journalistic writings.
Становление социально-семиотического подхода к анализу мультимодального дискурса: обзор зарубежного опыта
Authors:   Novosibirsk State Pedagogical University, Dutova Natalya V.
Published: October 2024

The article provides a brief overview of the origination of the foreign socio-semiotic approach to multimodal discourse analysis. Using the methods of diachronic analysis, interdisciplinary synthesis, abstraction and analogy, the author describes the formation and development of complex socio-communicative research technologies in combination with socially constructed cultural resources. Primary attention is paid to the development of multimodal research in social semiotics. The article characterizes M. Halliday’s idea of metafunctionality in relation to language and human social life, which paved the way for the study of the joint functioning of semiotic resources in various discourses to achieve communicative goals. The theory of R. Hodge and G. Kress, which accorded a semiotic status to everything related to humans and their activity, is described. In addition, G. Kress and T. van Leeuwen’s contextual approach to investigating multimodality and M. O’Toole’s visual grammar are presented as universal technologies for the study of semiotic resources. Some features of contextual and grammatical approaches within the framework of systemic functional multimodal discourse analysis are outlined. Particular emphasis is given to the description of R. Scollon’s, S. Wong Scollon’s and S. Norris’ multimodal interactive analysis. The importance of R. Scollon’s idea about discourse as a dynamic social practice and language as a tool for performing actions is highlighted. S. Norris’ attempt to establish a universal unit of multimodal analysis as the smallest unit of pragmatic analysis in communication involving any modality is presented. Visual transcription is described as an effective method of analysing communication mediated by modern digital technologies.
Свойства идиомы c точки зрения психо- и нейролингвистики

Published: October 2024

This article analyses idiom characteristics within the framework of the psycholinguistic paradigm and neurolinguistic experiments. The purpose was to describe and systematize the main properties of idioms relevant for the processing of such expressions by the brain, in particular perception, comprehension and production. Features suggested by both Russian and foreign researchers are considered. In addition, the problematic issue of terminology is addressed, as the terms often differ significantly between Russian- and English-language works. Due to the fact that Russian psycholinguists have paid less attention to phraseology, in this article the term idiom is used in accordance with the Western linguistic tradition, where it stands for a type of a phraseological unit whose meaning cannot be derived from the conjoined meanings of its elements. The results of the present study allow us to distinguish the following idiom characteristics: familiarity, frequency, conventionality, syntactic frozenness, decomposability, transparency, literal plausibility, predictability, and salience. Additionally, the research findings suggest that each of the abovementioned features may vary considerably among expressions, which drives us to the conclusion that idioms as a class are extremely heterogeneous. Furthermore, these characteristics directly influence idiom processing in the brain, which determines the time course of comprehension and accuracy of interpretation. According to the latest data obtained using neurolinguistic research methods, the degree of each feature’s manifestation in a given expression determines which brain region is activated and serves as the key factor contributing to hemispheric differences in idiom processing. The obtained knowledge about the processes occurring in the brain during perception, comprehension and use of idioms can be applied to improve the efficiency of teaching foreign languages and translation.
Проблема человека в философии И.А. Ильина
Authors:   Bunin Yelets State University, Usachev Aleksandr V.
Published: October 2024

Anthropological issues occupy a special place in Russian religious philosophy. This article examines the problem of man in the later works of prominent Russian thinker I.A. Ilyin (1883–1954). The paper aimed to demonstrate the characteristic features of humans in Ilyin’s philosophy. The methods used in the paper are: historical-genetic, hermeneutic, and comparative, as well as the methods of analysis, synthesis, and generalization. During the first two decades of the 20th century, Russia experienced three revolutions and two wars, which could not but affect the thinking of Russian philosophers. Thus, a question was raised about man as a subject of the changing points in history. Since every revolution brings a transformation in moral attitudes, providing the essential definitions of man was rather difficult. One thing was clear, however: humans are in the deepest crisis, and the only way out of it is through intensified spiritual work. A semantic gap appeared between the human proper as the bearer of revolutionary consciousness and a certain imperative of the essence of man, which must be brought to light and implemented in reality. A special place in the article is given to the problem of spirituality, which is a key component of humans if viewed in the context of revolutionary transformations. The crisis of spirituality is proposed to be considered as an indicator of the universal human crisis, which must be corrected on the path to spiritual renewal. The study suggests a point of view according to which spirituality is a fundamental quality of a person experiencing a crisis; it is the basis of human rebirth from revolutionary captivity and of the formation of man’s new image that is able to bring existence to full-fledged characteristics.

The article examines the main trends in the innovative development of enterprises in the chemical and petrochemical industries, which made it possible to determine their role in increasing the competitiveness of enterprises in other sectors of the economy of the Russian Federation. Examples of import-substituting innovations in the industry are given. Using the example of the large-capacity polymer market, the main threats to ensuring the competitive sustainability of these enterprises have been identified. As a result, the relevance of the scientific task of developing existing models of organizational and economic interaction between participants in the production and supply chain of chemical products to increase its competitiveness in domestic and foreign markets based on the implementation of innovative processes is substantiated. A model for using the results of innovative activities in the market of large-scale polymers is proposed, which, unlike well-known models, involves the creation of a hierarchical system of local collaborations focused on the implementation of innovative processes in order to increase the competitiveness of manufactured products at various stages. The proposed approach to managing innovation activities at large enterprises producing large-scale polymers will make it possible to develop solutions for using the results of innovation activities, which can be extended to tens or even hundreds of small companies operating in the markets of the next processing stage. Such decisions included solutions for the entire chain of production and use of products, such as pre- and post-sale service, PR campaigns to promote results, collaboration with other industry players at the early stage of innovation development, and influence on regulators. The practical implementation of the developed model will help ensure the competitive sustainability of enterprises of the petrochemical complex of the Russian Federation in the context of modern challenges.

Marfan syndrome (MFS) is a heritable disorder of connective tissue resulting from pathogenic variants of the fibrillin-1 gene (FBN1). MFS is rare and the most severe form of MFS, involving rapidly progressive cardiovascular dysfunction leading to death during early childhood. The constant enrichment of the MFS mutation spectrum is helpful to improve our understanding of genotype–phenotype correlations in the disease. Our patient carries a de novo variant of FBN1, homozygous c.1415 G > A (C472Y), heterozygous 1875 T > C (N625), heterozygous IVS 17-46 A > G, IVS 35-19 A > G, IVS 40-13_14insT, IVS 45+28_29insT, IVS 51-85 T > C, IVS 53-21 A > T, heterozygous 6855 T > C (D2285), homozygous IVS 56+17 C > G, homozygous IVS 60-113 C > A, heterozygous IVS 62 + 8 A > C. There is a case report in which a patient is diagnosed with missense variant S713G, this sequence analysis also identified a heterozygous 6289 G > T nucleotide change in the FBN1 gene of this individual. At this time, there is not sufficient information to classify this allele as a disease-associated mutation or a benign variant not associated with disease

Published: October 2024

Given the wide distribution of software and its current growth, security is inevitable, and software systems have become more complex. To avoid the complexity and protect valuable assets of software systems, researchers, and practitioners in the fields of security requirement engineering (SRE) and security assurance advise incorporating security requirements early in software development life cycle (SDLC). Nowadays, security requirements specification and identification are an active research area for ensuring the effectiveness of software systems. However, security requirement identification is a challenging task due to sheer numbers of threats and attacks to a software system. Previous researchers have identified different SRE techniques, each looking at the same problem from a different perspective. Therefore, a literature review conducted on SRE techniques. We compared and analyzed different SRE techniques to find the most suitable SRE techniques for researchers and practitioners. Selected SRE techniques compared based on various parameters, such as different attributes, requirement elicitation, requirement analysis, project size, and integration of standards. The literature also indicates that among SRE approaches, security quality requirements engineering (SQAURE), secure tropos, security requirements engineering process (SREP), and comprehensive lightweight application security process (CLASP) are the most used SRE approaches that focus on activities such as threats, security requirements identification, and security objectives identification. Unfortunately, several SRE approaches fail to explicitly integrate the security standard and security assurance perspective. Three questions developed for this study: Question 1 is based on comparison of existing SRE approaches, Question 2 is based on SRE with security requirements elicitation and analysis, and Question 3 highlights the incorporation of security requirements assurance by SRE approaches implicitly or explicitly. The researcher must work with the developer to easily adopt SRE approaches to elicit and ensure security requirements for the software system.

Published: October 2024

This paper introduces a fully differential CMOS active inductor integrated with a cascoded current mirror, tailored for applications within the RF frequency range. The active inductor design is meticulously realized using CMOS 0.18-µm technology. The circuit implementation comprises a fully differential cross-coupled pair of transistors, strategically employed to impart negative feedback, thereby enhancing the quality factor (Q). The cascoded current mirror functions as a pivotal biasing component, facilitating control over the current source to modulate negative feedback and Q factor tuning. Simultaneously, two resistors integrated into the differential structure are crucial in managing the frequency spectrum. Simulation results substantiate a Q factor of 16k, coupled with an inductance of 14 nH, prominently achieved at 3 GHz frequency.  Additionally, the objective of achieving a robust Q factor at 3.5 GHz, amounting to 500, is successfully realized. Noteworthy is the adaptability in achieving a frequency range spanning 2 GHz to 3.6 GHz by manipulating resistor values. Furthermore, the study observes that manipulation of supply voltage and current source enables the tuning of Q factor values from 70 to 16k. A performance assessment, juxtaposed with previously published works, underscores the viability of the proposed active inductor for applications within the gigahertz frequency range of RF.

A network application is an application that runs on a single host and facilitates communication with another application running on a different computer or host. Numerous network applications have been introduced, including cloud computing, SaaS, SOA, and microservices. However, these technologies have often been used interchangeably, leading to confusion among developers and researchers. Therefore, the objective of this study is to review and compare the available network applications, specifically cloud computing, Software as a Service (SaaS), Service Oriented Architecture (SOA), and microservices. This study conducts a comparative analysis by examining several important criteria such as definition, type, language, interoperability, characteristics, and examples. By providing clear and precise definitions for each technology, the study aims to clarify their distinctions and appropriate usage contexts. The findings successfully establish the correct terminology for each technology and offer detailed discussions on the specific platforms and situations where each is most suitable. This comprehensive review serves as a valuable resource for developers and researchers seeking to navigate the complexities of modern network applications.

The chemical similarity found in hydroxyapatite (HA) with natural bone makes it a popular choice for bone replacement. Therefore, in recent years, there has been an increasing tendency towards manufacturing HA from biological sources or waste, such as animal bone waste. Using naturally derived HA can benefit the economy, the environment, and human health. Therefore, this paper reports on the extraction of HA from cow bone waste using a simple and cost-effective technique. The bone powder was calcined in a furnace at temperatures ranging from 700°C to 1000°C for two hours. Then, the synthesized HA was characterized using a Field Emission Scanning Electron Microscope (FESEM), Energy Dispersive X-ray Spectroscopy (EDX), Fourier Transform Infrared Spectroscopy (FTIR), and X-ray diffraction (XRD). FESEM images revealed that HA particles with non-uniform spherical morphology were produced where the size increases with the calcination temperature. This finding is consistent with the average value of particle diameter measured at a temperature of 1000°C (0.783±0.268 µm) which is much greater than at a temperature of 700°C (0.272±0.128 µm). EDX analysis revealed that the Ca/P ratio value obtained in this study indicates non-stoichiometric HA production. XRD analysis shows that only the HA phase is present and there is no secondary phase generated from the calcination process. Meanwhile, FTIR analysis can detect the main group elements of the HA which were OH- and PO43-. The findings obtained in this study prove the effectiveness of this method in producing highly crystalline HA powder from cow bone waste using the thermal treatment method.

Poly (3-hexyl-thiophene-2,5-diyl) (P3HT) material is widely used as the benchmark of p-type semiconductors in organic photovoltaics due to its high conductivity and self-assembly into nanowires. In this study, gold-doped P3HT nanowires were synthesized using o-xylene, and their optical and electronic changes were investigated. P3HT nanowires were kept in the dark for 72 hours to obtain 60 – 80 nm diameter of nanowires. 1 mM of chloroauric acid doping was used as glass-coated P3HT nanowires were dipped repetitively into the chloroauric acid solution. It was found that visible absorbance intensity reduced and the calculated optical bandgap energy of P3HT nanowires thin film decreased as much as 0.08 eV after doping. FTIR and Raman show there are no extreme changes in P3HT conjugated backbones structure after doping meaning that the gold did not completely integrate within nanowires. From this observation, we discussed the feasibility of this coating method to produce metal-doped organic film and the required improvement to suit photonic device applications.

This study investigates how underground fire water systems using Glass Reinforced Epoxy (GRE) pipes are affected by aging. Over time, GRE pipes can degrade, potentially reducing their expected lifespan. The study compared damaged and undamaged areas of pipes to assess how damage impacts their structural integrity. Microscopic and chemical analyses (SEM and EDX) were performed on pipe samples from different locations of the pipe. Mechanical testing (following ASTM standards) was conducted beforehand. Analyses revealed that as damage increased (closer to damaged area), the levels of carbon (C) and oxygen (O) changed significantly with the weight percentage exposed 45.62% difference and 11.62% difference, respectively, as compared with the undamaged area. This suggests that the epoxy resin degrades with age, releasing these elements. Additionally, the presence of foreign objects around the pipes can affect how they bear loads. These findings highlight the importance of understanding how aging and surrounding conditions can influence the performance of GRE pipes in real-world fire water systems.
