Potential of elites in consolidation of public opinion in eastern and western approaches

The authors proceed from the classical understanding of the elite as a social group endowed with power and capable of influencing public opinion. The paper represents the examination of the role of elites – political, economic and social – in the formation of public ideas, values and political attitudes. The problem is conditioned, on the one hand, by the intensification of geopolitical confrontation and the formation of polar ideological concepts on both sides of the ocean, on the other hand – by the dynamic change in characteristics of media environment, which lead to increased centrifugal processes and polarization of public opinion on current events, values and ideology. The authors take into account the widely accepted hypothesis of relative homogeneity of elites (Huntington, Sklair) in the sense that cultural differences and stereotypes influence decision-making in this environment the least. This assumption became the starting point in choosing the topic, predetermined the search for possible points of contact in building a public dialogue, and, in general, served as the basis for a conceptual assessment of the ability of elites to resolve insurmountable contradictions between different segments of the political media space. The authors identified similarities and differences in the understanding of the social and political role of elites in the East and West and proposed possible routes for the development of dialogue. The study is based on the works of the classics of the theory of elites, as well as on modern research in the field of social communication and media.

Imaging swiFTly: streaming widefield Fourier Transforms for large-scale interferometry

We describe a scalable distributed imaging algorithm framework for next-generation radio telescopes, managing the Fourier transform from apertures to sky (or vice versa) with a focus on minimising memory load, data transfers, and computation. Our algorithm uses smooth window functions to isolate the influence between specific regions of spatial-frequency and image space. This allows the distribution of image data between nodes and the construction of segments of frequency space exactly when and where needed. The developed prototype distributes terabytes of image data across many nodes, while generating visibilities at throughput and accuracy competitive with existing software. Scaling is demonstrated to be better than cubic in problem complexity (for baseline length and field of view), reducing the risk involved in growing radio astronomy processing to large telescopes like the Square Kilometre Array.

МЕТОД КОДУВАННЯ ВІДЕОДАНИХ В СПЕКТРАЛЬНО- ПАРАМЕТРИЧНОМУ ПРОСТОРІ

It is shown that the development of modern infocommunication systems is followed by the trend of widespread use of wireless technologies. The level of intellectualization of the protocols of their functioning is increasing. Accordingly, the characteristics of wireless infocommunication technologies for data transmission are increasing. This contributes to their use for data transmission from remote robotic platforms in the process of information support for the functioning of critical infrastructure. It is substantiated that the transmission of video data with the required level of bit intensity on the basis of existing on-board telecommunication technologies is organized under conditions of significant time delays. Consequently, the level of efficiency of information delivery is lost. On the other hand, there are losses in the reliability of video information. It is argued that the option for solving the problem lies in the further development of technologies for encoding video information streams. The most common platform is the JPEG format. However, the city has disadvantages. They refer to the loss of compression levels in the event of a reduction in the potential for detecting psychovisual addictions. The article substantiates an approach for improvement, which consists in the use of an adapted coding technology in the spectral-parametric space. This approach consists in detecting subbands in spectral arrays and their subsequent parameterization with the formation of structural components at a significant level and length. Further processing is proposed to be carried out taking into account the informativeness of segments and reducing the amount of structural redundancy. An approach for constructing a technology for compression of spectral arrays with the detection of spectral sub-bands is substantiated. A model has been created to find the amount of information for transformed segments in the spectral-parametric space. This takes into account the available amount of redundancy, which is established by determining the constraints on the values of structural components. A method for encoding segments in spectral-parametric description has been developed. The main basic components of the method relate to the processing of sets of two-component structural-parametric components, taking into account the peculiarities of their content depending on the presence of quantization processes.

The authors believe that positive feedback in the joint evolution of artificial intelligence (AI) tools and personal segments of the open educational space will contribute to the transformation of the existing information society into a learning society. This makes it possible to form a system of open meta-education according to the needs of each individual.

Based on the results of the work, the authors conclude that digital platforms and social networks are widely used in Bulgaria today for effective socio-political communication with voters and in shaping public opinion of the country's population.

IMEC (India-Middle East-Europe Economic Corridor) project: uncertainty management vector

Another war in the Middle East. It would seem that it is another act in a the very old confl ict between Israel and Palestine. What’s the difference? Why should this act radically change the Middle East and very likely not only it? In this regard, the authors consider it necessary to provide a brief description of the new approach to operating stage-by-stage military confrontation as a tool for uncertainty management through the IMEC (India-Middle East-Europe Economic Corridor) project. The article substantiates the methodology of shock power confi guration of important segments of the world economic space in the interests of a group of leading actors in the world economics and politics. The geostrategic paradigm of the beneficiary, which needs a controlled conflict in the common interests of the future of the fractal sets of explicit and latent participants in such geostrategic operations, has been established.

Evaluation of different mechanical cleaning protocols associated with 2.5% sodium hypochlorite in the removal of residues from the post space.

This study evaluated the effectiveness of different mechanical protocols using rotary brush (RB), ultrasonic tip, and oscillatory system (OS) associated with 2.5% sodium hypochlorite (NaOCl) in the removal of residues and dentin permeability in the cervical and apical segments of the post space. Experimental in vitro study. Forty roots from human first molars were prepared and divided into four groups according to the cleaning protocols: Control (CO), NaOCl 2.5% conventional irrigation with a syringe; RB associated with NaOCl 2.5%; ultrasonic tip (US) associated with NaOCl 2.5%; OS associated with NaOCl 2.5%. The persistence of residues was evaluated by scanning electron microscopy and data submitted to Kruskal-Wallis and Dunn tests, and dentin permeability evaluated by confocal microscopy and date submitted to ANOVA one-way and Tukey's tests (P = 0.05). There were no differences in residue cleaning among the CO, RB, US, and OS groups, regardless of the analyzed root segment (P > 0.05). When comparing groups, dentin permeability in the CO group was significantly lower in the cervical segment (P < 0.05). The OS group promoted the highest permeability value in the apical segment. RB, US, and OS are similar in removing residues from the post space. However, OS results in higher dentin permeability in the apical segment.

Measuring Trajectory Similarity Based on the Spatio-Temporal Properties of Moving Objects in Road Networks

Advancements in navigation and tracking technologies have resulted in a significant increase in movement data within road networks. Analyzing the trajectories of network-constrained moving objects makes a profound contribution to transportation and urban planning. In this context, the trajectory similarity measure enables the discovery of inherent patterns in moving object data. Existing methods for measuring trajectory similarity in network space are relatively slow and neglect the temporal characteristics of trajectories. Moreover, these methods focus on relatively small volumes of data. This study proposes a method that maps trajectories onto a network-based space to overcome these limitations. This mapping considers geographical coordinates, travel time, and the temporal order of trajectory segments in the similarity measure. Spatial similarity is measured using the Jaccard coefficient, quantifying the overlap between trajectory segments in space. Temporal similarity, on the other hand, incorporates time differences, including common trajectory segments, start time variation and trajectory duration. The method is evaluated using real-world taxi trajectory data. The processing time is one-quarter of that required by existing methods in the literature. This improvement allows for spatio-temporal analyses of a large number of trajectories, revealing the underlying behavior of moving objects in network space.

The Language Resources of the Russia’s Foreign Humanitarian Policy: The Digital Components

The rapidly changing geopolitical situation has dictated the need for a conceptual design of the humanitarian policy of the Russian Federation abroad as a direction of foreign policy that is gaining priorities. The formation of an objective perception of Russia in the world involves systematic interaction with foreign audiences through digital infrastructure. Numerous digital platforms, being created by foreign tech giants, with their own rules and standards, compete with states, influence public opinion and public discourse. The “Russian language” of one of the largest segments of the digital space is ambivalent: in other words, it does not always mean a complimentary attitude towards Russia and Russian culture. Based on the available and collected data of Internet statistics, an assessment is made of the role of Russian-language digital resources as an opportunity to achieve the goals of Russia’s foreign humanitarian policy. On the example of the RuWiki, the Russian-language section of the Wikipedia online encyclopedia, it is shown how social media can be used in an ideological and value confrontation. In a comparative vein, Russian initiatives in the creation and promotion of national digital platforms are described on the example of encyclopedic portals - “Knowledge” based on the Great Russian Encyclopedia and Runiversalis. The main directions of humanitarian policy in the digital space are outlined, considering the geopolitical context. It is concluded that the development of domestic digital infrastructure will create a common semantic field for gravitation towards Russia, the Russian language and culture, regardless of the geopolitical situation. It is suggested that the formation of a more pronounced Russian-speaking segment of the global network reflects the idea of a multipolar world defended by Russia.

On positive systems with multivariable positive control: Process stabilization

The process stabilization is tackled from the perspective of a family of positive systems with multivariable positive control. This framework is consistent because each of the n state variables and m control inputs in chemical processes is in R+. The aim is to provide multivariable positive feedback control schemes which take values in the hyperbox U∈R+m; while sufficient conditions are satisfied to ensure the stabilization process. Two approaches are discussed: the first is a sliding mode control based on hyperplanes intersecting a (n−m)-dimensional segment of the state space which comprises the equilibrium point; such scheme guarantees robust stability. The second is a continuous feedback stabilizer based on Lyapunov functions, which enhances convergence rate while stabilization is ensured. The process stabilization is shown with two examples: a heat exchanger and an isothermal continuous stirred tank reactor. Both examples illustrate the usefulness of the proposed framework of multivariable positive control.

Motion Primitive Approach to Spacecraft Trajectory Design in a Multi-body System

The increasing number and variety of spacecraft that are expected to operate within cislunar space and other multi-body gravitational environments throughout the solar system necessitates the continued development of strategies for rapid trajectory design and design space exploration. In the field of robotics, similar needs have been addressed using motion primitives that capture the fundamental building blocks of motion and are used to rapidly construct complex paths. Inspired by this concept, this paper leverages motion primitives to construct a framework for rapid and informed spacecraft trajectory design in a multi-body gravitational system. First, motion primitives of fundamental solutions, e.g., selected periodic orbits and their stable and unstable manifolds, are generated via clustering to form a discrete summary of segments of the phase space. Graphs of motion primitives are then constructed and searched to produce primitive sequences that form candidate initial guesses for transfers of distinct geometries. Continuous transfers are computed from each initial guess using multi-objective constrained optimization and collocation. This approach is demonstrated by constructing an array of geometrically distinct transfers between libration point orbits in the Earth-Moon circular restricted three-body problem with impulsive maneuvers.

Multiscale Spatial Patterns in Giant Dike Swarms Identified Through Objective Feature Extraction

AbstractDike swarms are ubiquitous on terrestrial planets and represent the frozen remnants of magma transport networks. However, spatial complexity, protracted emplacement history, and uneven surface exposure typically make it difficult to quantify patterns in dike swarms on different scales. In this study, we address this challenge using the Hough transform (HT) to objectively link dissected dike segments and analyze multiscale spatial structure in dike swarms. We apply this method to swarms of three scales: the Spanish Peaks, USA; the Columbia River Flood Basalt Group (CRBG), USA; the Deccan Traps Flood Basalts, India. First, we cluster dike segments in HT space, recognizing prevalent linearly aligned structures that represent single dikes or dike packets, with lengths up to 10 − 30x the mapped mean segment length. Second, we identify colinear and radial dike segment mesoscale structures within each data set, using the HT to segment swarms into constituent spatial patterns. We show that for both the CRBG and Deccan Traps, a single radial or circumferential swarm does not well characterize the data. Instead, multiple and sometimes overlapping mesoscale linear and radial features are prevalent suggesting a complex history of crustal stresses. The HT can provide useful insights in a variety of geologic settings where many quasi‐linear features, at any scale, are superimposed spatially.

Medical discourse as a social activity: formation, priorities, dynamics (based on the material of the Russian popular science magazine «Zdorovie»)

Increasing interest in society in topics related to medicine and health is due to the current trend to consider physical, mental and social well-being as a basic human need. In the context of modern life, health is perceived as one of the most important values of an individual and society as a whole, therefore, medical discourse today plays a special role in culture, covering not only the professional expert and scientific community, but also the widest audience - the audience of the media. The media play a key role as a source of medical information and its targeted and targeted distribution. In this article, the medical discourse is analyzed in terms of its formation as a social activity and the role of modern mass media in it. The aim of the study is to analyze the demand for medical discourse in society and the features of its mediatization, which is the most important factor in the value-semantic dynamics of society and its way of life. The main empirical material is publications in the magazine "Zdorovie", the most popular Russian publication about a healthy lifestyle, medicine, practices for the treatment and prevention of diseases, the art of preserving beauty and vitality. The discourse of the popular scientific magazine "Zdorovie" as a very important segment of the value-semantic space of modern media is represented by a set of genres aimed at disseminating theoretical and practical medical knowledge, experience and providing medical services, taking into account the characteristics of medical subjects. dis-course, their information needs and problem-thematic requests, goal-setting attitudes, the degree and nature of interest, as well as the level of professional, general cultural and communicative competencies.

Smooth Interpolation Design with Consideration of Corner Tolerance Constraints for Robotics

This paper presents a novel method for interpolation design that ensures the continuity of a velocity profile and satisfies a specified corner tolerance constraint. The method uses an S-shaped profile to generate trajectories for each line segment in the task space. The velocity profiles of each segment are overlapped to control the smoothness of the corners and reduce the cycle time. This study defined an overlapping time parameter that is associated with the corner tolerance and the cycle time. Moreover, a corner tolerance constraint equation was derived that can allow for a given tolerance to be satisfied. This constraint equation enables the use of the proposed velocity profile overlap (VPO) method to specify corner tolerances for each corner of the trajectory. The proposed method was compared against the conventional acceleration/deceleration after interpolation (ADAI) method. The results demonstrate that the proposed VPO method can achieve higher accuracy and lower cycle time than the ADAI method.

Магия слова Оскара Лёрке: в поиске аутентичности художественного высказывания

The research is devoted to the problem of artistic language, in particular, the German-language lyric poetry of the XX century. The object of the study is just one segment of the cultural space, i.e. “magical” nature poetry, which most vividly reflects the process of changing cultural paradigms and artistic orientations. The aim of the study is to identify the features and the moral-aesthetic orientation of the creative work of Oskar Loerke, the founder of magical nature poetry. The research is novel in that it is the first to analyse the artistic language of Loerke’s lyric poetry in the aspect of the author’s artistic activity theory. It is the first time that Loerke’s magical nature poetry is being considered as one of the ways to solve the poet’s creative task, i.e. the search for a new authentic artistic language in the epoch of cultural crisis. The relevance of the poet’s use of the magic word is substantiated, the basic principle of artistic space organisation based on dialogue is revealed. The researcher considers the poet’s belief in the extraordinary power of the word to be the main feature of Loerke’s lyric poetry, which brings his notion of the word closer to magic. However, the poet recognises the independence of the object to which the word is directed, its ability to exist, thus creating a dialogue situation. Dialogue becomes a key principle in the organisation of Loerke’s poetic world. As a result, it has been proved that by turning to the magic of the word, the poet solves the problem of the authenticity of a statement at the level of the organisation of the artistic image, creating the situation of experiencing a creative act – the making of a work.

Dribble Accuracy and Arm Coordination Pattern According to Motor Expertise and Tempo.

Skilled movements in motor learning result from efficiently controlling the many degrees of freedom in human movement. To acquire motor skills, harmonious coordination of body segments in time and space is crucial for accurate and consistent performance. The purpose of this study was to compare dribbling accuracy, consistency, and coordination patterns of body segments according to motor expertise and tempo. To achieve this, we had eight basketball experts and eight beginners perform static dribbling at three different speeds for 20 s. Force plates measured radial error while motion capture equipment measured the angular data of the right arm's fingers, wrist, and elbow. The measurements obtained from the force plate were used to analyze the participants' dribbling performance, including accuracy, consistency, and coordination patterns. The research results showed that there was no significant difference in dribbling accuracy according to skill level, but skilled players showed higher consistency in the anterior-posterior (AP) direction (p < 0.001). In the comparative analysis of coordination patterns, skilled players showed an in-phase structure, whereas beginners showed an anti-phase structure (elbow-wrist: p < 0.05; wrist-finger: p < 0.001; elbow-finger: p < 0.001). This study suggests that achieving proficiency in basketball dribbling requires a strategy that involves coordination of movements with an in-phase pattern for stability in performance.

User Request for Content Produced by Female Influencers Online

The article represents the trends in information content, which is produced by the most popular Russian women bloggers. The purpose of the article is to study the discursive fields formed by female influencers in the Russian segment of the online space. Women influencers are able to formulate the gender specificity of published content, which leads to the transformation of discursive fields, first in the online space, and then in offline reality. The main channel of communication between influencers and the target audience is social media, which, on the one hand, provide an illusory freedom of expression, on the other hand, build a new, latently functioning hierarchical system for managing public opinion. Having a direct channel of communication with the audience, female influencers are able to broadcast the gender agenda, reproduce gender stereotypes, fixing them in the existing transit of social action from online to offline space. As a result of the network and linguo-discursive analysis, conclusions were drawn about which discursive fields broadcast by female influencers are the most popular among users, which in the future will not only construct their lifestyle, but also affect the perception of the gender agenda that reveals various aspects of a woman (self-realization, family, career, politics, education, etc.).

Client-Centric Concept in Higher Education: Russian and International Experience of Implementation

The client-centric concept, which originated in the 1980s, has been implemented in the last decade in specific digital projects at the national and global level. Russia has fully embraced the new technological trend and is creating new types of digital services in different segments of the social space. The purpose of the article is to consider the stages of implementation of client-centric principles in global and Russian practice. The main emphasis is placed on the information superservice "University Admission Online" introduced in Russia and its counterparts in other countries of the world. The analysis showed that Russia has already passed the main stages of formation of such digital platforms and is in the group of the leading countries of the new initiative. International experience shows that the nearest analogues of Russian superservice have been created under the patronage of the state in Sweden and Germany. At the same time, the article shows that private global services in the higher education market already operate today – the Australian and the Anglo-Chinese initiatives, respectively. The question of expanding the digitalization of the Russian higher education market through the launch of global services in the framework of public-private partnerships is discussed.

Fast and Accurate Transient Analysis of Thin-Wire Structure in Half-Space With PEEC Method

This article presents an efficient full-wave partial element equivalent circuit (PEEC) method of thin-wire structure in half-space for lightning transient analysis. In the framework of the PEEC formulation for thin-wire conductors, the partial elements are computed by double-folded line integrals. In layered media, the interaction integrals involve dyadic Green's functions, which contain a closed-form part and a Sommerfeld-integral part. The direct numerical computation of these integrals is very challenging and time-consuming, which hinders the practical application of the full-wave method. However, the efficient and accurate evaluation of partial elements has not been investigated in a comprehensive way so far. Accordingly, this article presents an efficient method for the evaluation of the partial elements between elementary segments in half space. The main novelty is that the interaction integrals are computed through a combination of the Taylor series expansion of the full-wave free space Green's function and the Sommerfeld-integral adaptive interpolation technique, which significantly reduces the computation time. The new method is systematically validated on examples from finite-difference time-domain (FDTD) method and method of moments and experimental results. The proposed method is validated with the NEC code in the frequency domain and the FDTD in the time domain.
