The paper presents an analytical review of the application of biometric recognition systems in relation to facial image identification technologies. The classification of biometric systems is presented. The trends of technological progress in the field of biometrics and facial recognition capabilities are considered. It is determined that in 2020 there is a trend of transition from the use of biometric recognition technologies in traditional state security systems to the sphere of commercial and user applications. The process of «linking» encryption keys and passwords with the biometric parameters of the data subject is described. It is proposed that a biometric feature and a biometrics parameter mean a certain value that has a physical meaning that characterizes the subject itself. The possibility of using circular neighborhood and bilinear interpolation of pixel intensity values in biometrics is also presented. This will make it possible to build a local binary template. In order to solve the problem of identification of persons, it is advisable to investigate the essence of biometric systems in the technologies of identification of persons, their types, identifying the shortcomings of each of them, on the basis of which to present the directions of elimination and search for the most reliable technologies. The essence of the use of biometric systems in the technologies of identification of persons is, for example, that the user can provide the bank or other counterparty with evidence that it is he who wants to use the services on his accounts. At the same time, the demand has increased for contactless biometric solutions. These technologies are implemented in order to conduct additional biometric verification of users. This allows to minimize possible fraud or violation of the internal rules of the service, for example, the transfer of accounts of some registered users to others.

The Subject

Topography is the most important component of the geographical shell, one of the main elements of geosystems, and the framework of a landscape. geomorphometry is a science, the subject of which is modeling and analyzing the topography and the relationships between topography and other components of geosystems. Currently, the apparatus of geomorphometry is widely used to solve various multi-scale problems of the Earth sciences. As part of the RFBR competition “Expansion”, we present an analytical review of the development of theory, methods, and applications of geomorphometry for the period of 2016–2021. For the analysis, we used a sample of 485 of the strongest and most original papers published in international journals belonging to the JCR Web of Science Core Collection quartile I and II (Q1–Q2), as well as monographs from leading international publishers. We analyze factors caused a progress in geomorphometry in recent years. These include widespread use of unmanned aerial survey and digital photogrammetry, development of tools and methods for survey of submarine topography, emergence of new publicly available digital elevation models (DEMs), development of new methods of DEM preprocessing for their filtering and noise suppression, development of methods of two-dimensional and three-dimensional visualization of DEMs, introduction of machine learning techniques, etc. We consider some aspects of the geomorphometric theory developed in 2016–2021. In particular, a new classification of morphometric values is presented. We discuss new computational methods for calculating morphometric models from DEM, as well as the problems facing the developers and users of such methods. We consider application of geomorphometry for solving multiscale problems of geomorphology, hydrology, soil science, geology, glaciology, speleology, plant science and forestry, zoogeography, oceanology, planetology, landslide studies, remote sensing, urban studies, and archaeology.

This given article reveals the topicality not only of destructive, but also of constructive, as well as hybrid conflicts. Practically it has been done for the first time. It also describes the history of the formation of both foreign and domestic social conflictology. At the same time, the chronology of the development of the latter is restored and presented objectively, in full, taking into account the contribution of those researchers who actually stood at its origins. The article deals with the essence of the socio-psychological approach to understanding conflicts. The subject of social conflictology includes the regularities of their occurrence and manifestation at various levels, spheres and conditions, including normal, complicated and extreme ones. Social conflictology includes the theory and practice of diagnosing, resolving, and resolving social conflicts. It analyzes the difficulties that occur in defining the concept, structure, dynamics, and classification of social conflicts. Therefore, it is no accident that the most important task is to create a full-fledged theory of social conflicts. Without this, it is impossible to talk about effective settlement and resolution of social conflicts. Social conflictology is an integral part of conflictology. There is still a lot of work to be done, both in theory and in application, for its complete design. At present, there is an urgent need to develop conflict-related competence not only of professionals, but also for various groups of the population.

The aim of the study is to describe the titles of Latvian metal music albums, from the perspective of content, by identifying the common and distinctive character of the metallic music tradition, and perhaps even the local one. Of 241 album titles (data on Dec. 31, 2019), most are in English, some in French, Latin, Russian, some consisting of digits, and 69 titles in Latvian. These titles are the subject of the research. The main source is Encyclopaedia Metallum (www.metal-archives.com), which still does not reflect the current situation concerning Latvian metal music. Album titles in this study are viewed separately from album designs and song titles and are analysed from the perspective of content. The album title is an important part of the work that has been issued because it is an element that makes the audience/buyer pay attention to the album because it must not be forgotten that today the album is also an item that you want to sell. In general, it can be concluded that Latvian metal musicians, with their album titles in Latvian, are mostly following world trends, as evidenced by the integration in the researcher Deena Weinstein’s classification of Dionysian discourse and discourse on chaos. Most titles are more relevant to the discourse on chaos because the thematic circle of chaos is wider. Latvian mythology, along with history, is an up-to-date source for the creative work of bands that is responsible for the local feeling of the titles. A large enough number are titles that are difficult to fit in the Weinstein’s division and form the third group with philosophical titles and simply all sorts of titles. If the philosophical titles follow the world’s trends, the simple titles include the names of the events, tributes, and the titles of literary works, which give them a local character.

The classification of Russian culture-bound terms used in the novel “Quiet Flows the Don” by M. A. Sholokhov and in its translation into the English language. The novel “Quiet Flows the Don” by M.A. Sholokhov and its translation into English done by Robert Daglish have served as the source for the research of culture-bound terms. These terms have been classified on the basis of the subject division offered by S. Vlakhov and S. Florin. It is proved that the interest to the study of culture-bound terms is still important. The relevance of the research is determined by the fact that despite numerous research papers in this field the origin, classification and translation of these terms still need some investigation. The aim of the present study is to classify the culture-bound terms taken from the novel “Quiet Flows the Don” by M.A. Sholokhon and its translation into the English language. As a result, there have bben taken 407 samples of the lexical units with a cultural component which were classified according to the subject principal offered by S. Vlakhon and S. Florin. The culture-bound terms have a great influence on a foreign reader as they are cultural units that transmit the information of the daily routine and the historical epoch described in the novel. The culture-bound terms taken from the novel “Quiet Flows the Don” by M.A. Sholokhov and its translation are analyzed and classified. The division of the culture-bound terms according to the subject principal allowed to reveal that most terms refer to the daily routine, social and political life and military terms.

In this paper are recorded the results of an investigation undertaken at the instance of Dr. A. Smith Woodward for the purpose of ascertaining to what extent the pattern presented by the calcified laminæ of the centrum is of value as an aid to the classification of Elasmobranch fishes, and to the identification of vertebræ found in the fossil state. The subject was dealt with exhaustively in 1879-1885 by Hasse, who, in his monograph ‘Das natürliche System der Elasmobranchier,’ claimed that the differences in the disposition of the calcified laminæ in the various genera and families of Elasmobranchs occur with such constancy and regularity that they may be accepted with confidence as an important factor in taxonomy. During the years, however, that have passed since the publication of this monograph the thesis has come to be looked upon with suspicion, and vertebrate morphologists at the present time do not, as a whole, regard Hasse’s definitions of the Cyclospondyli, Tectospondyli, and Asterospondyli as consistently applicable to the genera and species included by him within those groups. The material studied in the course of the investigation was to a large extent accumulated several years ago (see p. 313), and it was only the superior attraction of Cephalodiscus as a subject of research that prevented the work from being brought to an earlier conclusion. The examination of this accumulated material, and of that more recently acquired, was carried on in the Huxley Research Laboratory of the Imperial College of Science during the winter of 1917 and from May, 1919, to May, 1920, and I hereby acknowledge my great indebtedness to Prof. E. W. MacBride and the administrative officers of the College for the facilities offered there for the prosecution of the work. I have further to thank Prof. MacBride for frequent advice and for valuable suggestions made during the progress of the research. My thanks are also due, and are hereby tendered, to Dr. A. Smith Woodward and Mr. C. Tate Began, of the British Museum (Natural History), for many helpful hints and suggestions.

In recent years, gene selection for cancer classification based on the expression of a small number of gene biomarkers has been the subject of much research in genetics and molecular biology. The successful identification of gene biomarkers will help in the classification of different types of cancer and improve the prediction accuracy. Recently, regularized logistic regression using the L 1 regularization has been successfully applied in high-dimensional cancer classification to tackle both the estimation of gene coefficients and the simultaneous performance of gene selection. However, the L 1 has a biased gene selection and dose not have the oracle property. To address these problems, we investigate L 1 / 2 regularized logistic regression for gene selection in cancer classification. Experimental results on three DNA microarray datasets demonstrate that our proposed method outperforms other commonly used sparse methods ( L 1 and L E N ) in terms of classification performance.

Spatial Semantics

The relevance of the article is due to the importance of studying spatial semantics in the new scientific paradigm. The possibility of studying genre varieties of description (description-landscape, description-interior, description-portrait, description of the subject) using frame analysis is indicated in the article. Considerable attention is paid to the classification of spatial verb description predicates. It is noted that the unflagging interest in verbal units in modern linguistics, with unsteady classification grounds, different numbers of distinguished verb classes and terminological differences in describing the object, indicates the need to compile a classification of verb predicates based on the principles of linguocognitology. The study of the semantics of verb predicates of descriptive text, the identification of integrating and differential seme, contributing to the isolation of various lexical-semantic groups of verb predicates and building the patterns implemented in the description of spatial relationships appears to be significant. The attention is focused on the need to integrate linguistic, physiological and psychological knowledge in the study of the predicative component of a descriptive text. Such integration is embodied in the idea of spatial discrimination through all sensory systems and the division of spatial predicates into units of visual, auditory, olfactory, tactile, taste and undifferentiated perception. It is established that in the case of using predicates of intermodal semantics, spatial significance is realized in terms of “proximity” / “remoteness” of the source objects of the corresponding sensations.

Introduction. The article describes phraseological synonyms in Russian and Moksha subdialects on the territory of Mordovia. The subject of the analysis is the specific features of dialect phraseological units. The purpose of the study is to present a comprehensive description of the phenomenon of synonymy of phraseological turns in the considered subdialects. Materials and Methods. To achieve this goal, it employs various research methods, the main of which is descriptive one. In addition, it uses the elements of distributive and component analysis method. The language material was made up of phraseological units extracted by continuous sampling from the “Dictionary of Russian subdialects on the territory of the Republic of Mordovia”, Moksha-Russian dictionaries and field observations of the authors. Results and Discussion. As a result of the analytical review of the material, it is identified that in the phraseological units of both the Russian and Moksha languages develop synonymous series covered by the phenomenon of variance. The emergence of synonymous series is primarily associated with the renewal of the figurative basis of phraseological units belonging to the same topic. In the process of synonymous development of phraseological units, there is a search for a better image and linguistic means of constructing it while maintaining the unity of the logical side of the concept underlying it. Conclusion. The article is of practical importance, its results can be used in writing teaching handbooks on Russian dialectology, in teaching the course “Russian dialectology”, “Dialectology of the Moksha language” and corresponding courses for students majoring in Arts and Humanities.

The Impact

We consider the process of forming the iconic system of atlas mapping of the Baikal region. More than twenty atlases were created for the territory of the Baikal region and published. Fifteen of these were selected by us for their general cartosemiotic study. We review the results of the analysis of the information-modular structure of atlases on the example of the map index in these atlases. It is shown that the number of information-semiotic modules in each atlas can vary and depends on its subject and purpose. The subject, structure and purpose of atlases are the cause of their complex and flexible modular-thematic semiotic structure. The analysis of the internal semiotic structure of atlases was carried out from the perspective of a single system of classification of conventional signs and graphic display methods on the example of three atlases: Atlas of Transbaikalia, Atlas of the Baikal Basin and the new atlas “Baikal region: society and nature”. The information and semiotic modules of the new atlas are formed according to the macrostructure of its thematic content, taking into account territorial levels and specific substantive thematic positions of mapping. When creating this atlas, we used effective methods of semiotic modeling and a certain balance and variety of applied syntactic constructions of cartographic signs. The atlas is being prepared for a printing publication as a work of a new kind, integrating modern information about the impact of socio-economic processes on the natural environment. The balance and diversity in the combination of various types, classes, groups and types of syntactic constructions of cartographic signs revealed during semiotic analysis of atlases of the Baikal region shows a high scientific level of map compilation and works on the general semiotic design of the publication of most atlases of the Baikal region.
