Currently, an increasing number of fiber-optic communication lines are reaching the end of their predetermined service life, yet the quality indicators of these lines still allow for continued operation. To extend the actual operational life of these lines, it is necessary to conduct high-quality monitoring of both the current status of all components and the dynamics of key indicators. This article proposes a method for addressing the challenge of maintaining communication network reliability while continuing to use optical cables after their warranty period has expired. A study of random values of the attenuation coefficient and polarization mode dispersion of an optical fiber, supported by actual operational data from a network segment, shows high temporal stability in the attenuation coefficient and polarization mode dispersion of optical fiber type G.652. This conclusion allows us to discuss the continued operation of optical cables after the warranty period. To analyze the key aging metric, mathematical models are used that take into account the physical and chemical properties of cables as well as the conditions of their proof-tests. Using an example related to the current state of Russian fiber optic networks, we calculate the number of emergency reserve elements necessary to maintain the reliability of their operation. Practical recommendations for the placement of emergency reserve are also provided.

The paper presents a new multimodal approach to analyzing the psycho-emotional state of a person using nonlinear classifiers. The main modalities are the subject’s speech data and video data of facial expressions. Speech is digitized and transcribed using the Scribe library, and then mood cues are extracted using the Titanis sentiment analyzer from the FRC CSC RAS. For visual analysis, two different approaches were implemented: a pre-trained ResNet model for direct sentiment classification from facial expressions, and a deep learning model that integrates ResNet with a graph-based deep neural network for facial recognition. Both approaches have faced challenges related to environmental factors affecting the stability of results. The second approach demonstrated greater flexibility with adjustable classification vocabularies, which facilitated post-deployment calibration. Integration of text and visual data has significantly improved the accuracy and reliability of the analysis of a person’s psycho-emotional state

The article discusses the problem of estimating the reliability of distributed data storage systems. The author concludes that classical models do not consider many of the capabilities of modern distributed systems, such as the ability of automatic data recovery on the rest of nodes. Such ability depends on several factors, including free and used space on nodes. This process means that such a system can recover nodes loss independently without the interaction with other agents, as system administrators, which might be required to configure new nodes for data recovery. After that, the author describes the main components of such a system, which reliability should be calculated. The parameters which are used in such an automatic data recovery are defined and added to the well-known methodology-based reliability estimating model for RAID. At the end, modelling of various data storage systems is carried out and the result of reliability estimation of these systems is compared with the systems that are based on the proposed automatic data recovery model.

Relevance: The knowledge economy in developing countries like Russia and India is dynamic and ever-changing. By researching the relationship between intellectual capital and financial performance, banks can create plans to manage their intangible assets efficiently, improving their financial performance, spur more innovation, and providing them with a competitive advantage. Research objective. This research aims to study the impact of the intellectual capital of the top banking companies in Russia and India on their financial performance. This research will investigate the potential effects of the following knowledge economy quirks on the correlation between financial performance and intellectual capital. Data and methods. This study includes a sample of the top eleven Russian banking companies constituents of the Moscow index and equivalent number of Indian Banking companies constituents of National Stock Exchange of India from 2011 to 2022. PLS-PM analysis has been employed to identify the intellectual capital components that predict the firm’s performance and the effect of intellectual capital components on the firm’s financial performance.

Data and Methods. To achieve these objectives, we used a quantitative approach, surveying 872 Thai participants through an online questionnaire using a convenience sampling technique. Additionally, we analyzed the data comparing e-commerce and s-commerce across Southeast Asian countries using the documentary method and content analysis. Results. Consumer spending through e-commerce and s-commerce has a significant positive impact on economic growth in Thailand, surpassing the impact of government spending. Private consumption, a substantial component of Thailand’s GDP, stimulates production, investment, and job creation, fostering overall economic advancement. In Southeast Asia, distinct e-commerce trends are evident: Thailand benefits from high internet and smartphone usage, Indonesia from robust social media engagement, and Vietnam from a focus on social commerce and mobile, cross-border e-commerce. These diverse trends underscore the necessity for businesses to tailor their strategies to each country’s unique consumer behaviors and preferences. Conclusions. The study confirms the significant impact of electronic consumption through e-commerce and social media on GDP growth. This form of consumption not only drives demand but also creates jobs, enhances efficiency, and opens up opportunities for international trade, fostering sustained economic development. In light of these findings, governments are advised to bolster digital infrastructure and support businesses in their digital transition. Meanwhile, businesses are recommended to adapt to digital models, emphasize consumer engagement, expand globally through online platforms, and integrate sustainable practices. Collectively, these measures are designed to harness the full potential of electronic consumption for sustainable and robust economic growth.

Процессы излучения и поглощения микро- и наночастицами рассчитываются с помощью формализма модовой теории излучений с использованием зависимости добротности электрически малых радиоантенн от их относительных (по отношению к длине излучаемой волны) размеров. Рассмотрено формирование радианной сферы, заполненной эванесцентными волнами (ТЕ, ТМ), вокруг поверхности излучающей частицы. Эти волны не излучаются в свободное пространство и представляют собой колебания электрических и магнитных полей на частотах ν < c/cutoff (например, для сферической частицы cutoff = 2,221D, где D – диаметр). Для излучений на длинах волн больших cutoff, частица перестает быть эффективной антенной. У таких частиц роль излучающих в дальнюю зону антенн выполняют окружающие их радианные сферы. Частицы, размеры которых больше излучаемых длин волн, сами являются эффективными антеннами. С помощью предложенной методики проведены расчеты мощностей и коэффициентов излучений микронных и нанометровых частиц.

Public Employment Services provide support for firms and individuals in finding new employment opportunities. They are important actors at the labour market, since well-functioning services reduce costs of search friction and increase matching efficiency. In this paper we adopt the regional classification scheme to identify similarities of regions and their PES on the basis of regional labour market-oriented characteristics. The purpose of the scientific search is the theoretical justification and empirical confirmation of Russian regions’ similarity in terms of employment level and the formulation of areas for increasing the efficiency of public employment services. The tasks were solved using expert analytical methods, analysis of statistical rows, clustering and cartography. The clustering is based on Ward’s hierarchical method, clusters are plotted on weighted standardised data. The official information from the Federal State Statistics Service of the Russian Federation (Rosstat) are analysed. We identified 7 clusters, in which PES have rather similar conditions. The heterogeneity of conditions is higher between clusters. PES within a cluster are valid for comparison and the adoption of new services and best practice examples. We show that the classification of the Russian Economic Zones does not necessarily cover similarities at local labour markets. The practical significance of the results is due to the possibility of using them to develop decisions for long - and short-term support for employment and the formation of an optimal labour market structure both at the state level and at the level of constituent entities of the Federation.

This article considers entropy analysis as a tool for assessing the sustainability and integration of regional economies into national and international economic systems. Three key types of entropy are de ned - economic diversi cation, income and employment distribution and interregional ties. The methodology for calculating entropy indicators based on the generalised Shannon entropy formula is presented. A comparative analysis of three hypothetical regions was conducted on the basis of entropy indices. The obtained results allow us to quantitatively assess the speci cs of regional development, identify imbalances and propose strategies to improve the sustainability and economic diversi cation of regions.

The paper presents a method for detecting false responses of localization and identification algorithms. The method considers matching image characteristics that cannot be described by local features stably and completely. It is proposed to use image zones containing such features, describe them and use them to assess the validity of the algorithm response. In the work we demonstrate how the algorithm works on ID documents. Possible features are images of the coats of arms and flags of countries, background filling and text unique to the considered document type. To illustrate the proposed algorithm, the MIDV-500 and MIDV-LAIT datasets were taken. The first is used to show that the rejector does not reject correct system responses, the second - that it rejects the incorrect ones. We test several methods of zone description. The experimental results show that false type selection decreases with the use of any description type and the local CNN-descriptor shows the best performance. The increase of classes with marked zones is shown to improve the filtration of false responses. The experiments show the improvement from by 13% with one type with zones to by 4 times with 10 types.

This article examines Russian culturonyms in contemporary American literature. American authors come from a variety of linguistic and cultural backgrounds, and their literary works often reflect translingual and/or transcultural features. The relevance of this article is owed to the expanding study of bilingual creativity among bilingual and bicultural individuals. Bilingual authors, who are also heritage language speakers, often possess linguacultural hybridity because they were raised with several languages and cultures. It is in their fiction writing that this hybridity is often expressed. The aim of this work is to reveal and analyze culture-specific words from Russian medieval linguaculture found in literary works of Nicholas Kotar and Olesya Salnikova-Gilmore, American writers of Russian descent. The bilingual heritage writers often opt for internal translation to describe Russian culturonyms to English-speaking readers. By doing so, bilingual and bicultural writers of Russian heritage introduce and familiarize English speakers with elements of Russian linguaculture. This, in turn, further contributes to the growing English-Russian contact in transcultural literature. In their English-language novels, Kotar and Salnikova-Gilmore skillfully incorporate and adapt Russian culture-specific words and concepts. The findings may provide insight into contemporary literary works written by bilingual heritage writers and their linguacultural hybridity, including the translation strategies implemented in their original interlinguacultural texts.
