Ornstein-Uhlenbeck Processes Simulation

In this paper we give a brief introduction to Ornstein-Uhlenbeck processes and their simulation methods. Ornstein-Uhlenbeck processes were introduced by Barndorff-Nielsen and Shephard (2001) as a model to describe volatility in finance. Ornstein-Uhlenbeck processes are based on Levy processes. Levy processes simulation may be found in [1, 2]

Application of Supercomputer Technologies for Simulation of Socio-Economic Systems

To date, an extensive experience has been accumulated in investigation of problems related to quality, assessment of management systems, modeling of economic system sustainability. The studies performed have created a basis for formation of a new research area — Economics of Quality. Its tools allow to use opportunities of model simulation for construction of the mathematical models adequately reflecting the role of quality in natural, technical, social regularities of functioning of the complex socioeconomic systems. Extensive application and development of models, and also system modeling with use of supercomputer technologies, on our deep belief, will bring the conducted researches of social and economic systems to essentially new level. Moreover, the current scientific research makes a significant contribution to model simulation of multi-agent social systems and that isn’t less important, it belongs to the priority areas in development of science and technology in our country. This article is devoted to the questions of supercomputer technologies application in public sciences, first of all, — regarding technical realization of the large-scale agent-focused models (AFM). The essence of this tool is that owing to increase in power of computers it became possible to describe the behavior of many separate fragments of a difficult system, as social and economic systems represent. The article also deals with the experience of foreign scientists and practicians in launching the AFM on supercomputers, and also the example of AFM developed in CEMI RAS, stages and methods of effective calculating kernel display of multi-agent system on architecture of a modern supercomputer will be analyzed. The experiments on the basis of model simulation on forecasting the population of St. Petersburg according to three scenarios as one of the major factors influencing the development of social and economic system and quality of life of the population are presented in the conclusion

Technology for test-systems for diagnosis of modified proteins (proteopathy) underlying social diseases (Report 1)

A new experimental technique for obtaining diagnostic test systems is introduced based on conjugates "polymer microsphere–bioligand" for rapid diagnosis of autoantibodies to the modified protein on example of thyroglobulin, which consists of preliminary blocking of aldehyde groups of polymer microspheres by glycine amine groups, and then of the covalent interaction between carboxyl group of glycine and the amino groups of thyroglobulin. This way of creating test systems has enhanced the sensitivity of the reaction of latex agglutination (RLA) by extending the boundaries of titer.A new experimental technique for obtaining diagnostic test systems is introduced based on conjugates "polymer microsphere–bioligand" for rapid diagnosis of autoantibodies to the modified protein on example of thyroglobulin, which consists of preliminary blocking of aldehyde groups of polymer microspheres by glycine amine groups, and then of the covalent interaction between carboxyl group of glycine and the amino groups of thyroglobulin.

MODERN ANALYSIS METHODS USE IN ORDER TO ESTABLISH THE GEOGRAPHIC ORIGIN OF FOOD PRODUCTS

Food products with controlled geographical origin place are in special demand among consumers because of their specific properties, due to climatic, soil characteristics or other factors. The article provides an analysis of regulatory framework for legal goods protection with an indication of their origin place on the territory of the Russian Federation and in other countries. Existing authentication methods for this type of product are reviewed. Based on the analysis of scientific literature, the authors noted the most significant works aimed at confirming the authenticity of food products’ origin place on the example of honey and meat products, which were carried out in the countries of the European Union, Australia, China, Brazil, South Africa, the USA and other countries. It is shown that the most widespread researches aimed at studying values of isotopic ratios of hydrogen (2H/1H), carbon (13C/12C), oxygen (18O/16O), nitrogen (15N/14N) and sulfur (34S/32S) in compounds contained in products that reflect the distribution of «light» and «heavy» isotopes during biological and geochemical processes within a single region. The analysis of the works aimed at studying the qualitative and quantitative composition of trace elements and rare earth metals (As, B, Ba, Cd, Li, Mn, Pd, Rb, Se, Te, Tl, Dy, U, etc.), as well as research of isotopic relations values of some elements (87Sr/86Sr, 207Pb/206Pb, etc.) in product samples and soils of studied region. The advantages of an integrated research approach, which includes the creation of data array of various indicators values and its in-depth analysis using chemometric algorithms and mathematical modeling methods, are shown.Food products with controlled geographical origin place are in special demand among consumers because of their specific properties, due to climatic, soil characteristics or other factors.

Sesen Ivanovich Bolo: Creative Portrait and Technology of Collecting Folklore

The article is devoted to the life of one of the founders of the Yakut field folklore S. I. Bolo. The relevance of the work is determined by the increased interest in folk textology and insufficient study of biography and scientific heritage of Yakut researchers. The novelty of the research is in the fact that the methods and principles of fixing the folklore text of S. I. Bolo are analyzed for the first time. His characteristic as a collector of folklore is given. The term “technology of collecting folklore” is proposed, which means a set of methods, principles, means of fixation of oral folk art. Based on the study of the key moments of life and activity of S. I. Bolo his creative portrait is created. As the author of the article shows, the phenomenon of S. I. Bolo is that he, despite the lack of appropriate education, has made significant progress in the field of folklore, has developed its own work technology. It is reported that in the conditions of hand-written fixation of folklore texts, he tried to accurately convey their linguistic features. It is noted that among all the genres of oral folk art, he was most interested in historical legends about ancestors, on the basis of which he built his theory of the origin of the Yakuts and compiled pedigrees tables. The author points out that the negative consequences of Stalin’s repressions and national policy in Yakutia prevented the wide dissemination of S. I. Bolo’s ideas and publication of the materials

Transformation of the Yakut Heroic Epos Olonkho: Statement of the Problem, Systematization and Periodization

The article is devoted to the transformation of the Yakut heroic epos. The relevance of the work is due to large changes in the epos creation of Yakut storytellers and insufficient study of this process in Yakut folklore. The novelty of the study is that for the first time the problem of olonkho transformation is specifically studied. Various changes in the epos in the genre, pragmatic, conceptual, ideological and other aspects are considered. Of particular note is the transition from the oral epos to the written form of being. It is established that the appearance of copyright works based on olonkho creates confusion in the definition of the genre, as a result of which various falsifications appear. The characteristic of the transformation of the concept of “olonkhosut” (narrator) is given. An author’s periodization of olonkho transformations is proposed, which consists of three stages: pre-revolutionary, Soviet and post-Soviet (modern). It is noted that each period has its own characteristics. The author of the article reveals some features of stage productions when traditional images and motives of olonkho are distorted to suit modern viewers' requirements. Summing it up, the author concludes that the transformation of the epos creates a great danger that can destroy the olonkho genre in Yakut folklore and change the idea of it in modern people

Transformation of Yakut Heroic Epos (by Material of Olonkho of B. A. Alekseyev “Erbechtay Mergen”)

The article is devoted to the transformation of the Yakut heroic epos on the example of Olonkho of B. A. Alekseyev “Erbechtay Mergen,” which was recorded by him and the folklorist-collector S. I. Bolo during the Vilyuisk expedition in 1938. The relevance of the work is determined by the increased interest in the transformation processes of the traditional culture of the Yakuts under the influence of the socio-cultural environment. The novelty of the study is that for the first time the local Olonkho text is studied as an object of transformation. Olonkho manuscript and the peculiarities of its recording are given. It is reported that in 2017 the author of the article prepared the Olonkho text for publication. The article establishes fabulous elements, demythologization, the influence of Russian culture as the cause of changes in Olonkho. As the author of the article shows, this Olonkho is characterized by cumulative actions of the characters, as in fairy tales. It is noted that the rivalry and strife of relatives enhance the domestic nature of the relationship between the characters and push the heroic image into the background. It is reported that due to demythologization the mythological motifs and images have become rare in Olonkho of B. A. Alekseyev. The author also points out that under the influence of Russian culture there have been some changes: a lot of words are borrowed from the Russian language, the names of Russian cities, the pantheon of deities began to include Christian images, there is a mixture of the image of Baba Yaga and abaasa women, there are images of Russian girls, etc

Representations of Cold in the Folklore Picture of World of Yakuts

The idea of cold, reflected in the folklore picture of the world of the Yakuts is discussed in the article. The relevance of the work is due to the increased interest in the northern (Arctic) topic, in particular, to the issue of perception of cold by indigenous peoples, which has its own characteristics, ancient and late strata. The novelty of the study lies in the fact that for the first time folklore material is more widely covered, a comparison is made with the features of the perception of cold by other peoples; modern transformations are revealed. The author of the article uses texts of different folklore genres as a material for study: epics, legends, mythological stories, folk songs, tales, proverbs and sayings. The semantics of the word tymny (cold), which has figurative meanings with a negative connotation, is described. It was revealed that in the folklore picture of the world of the Yakuts, the cold is represented in the images of Winter and North, the mythological Bull of Winter, the Lower World inhabited by the abaasy monsters, the Aam-Daan cold, astral objects (constellations, planets). It is reported that folklore reflects not only the negative attitude of the Yakuts to cold, but also the ways of their adaptation to harsh climatic conditions. It is established that at present the idea of cold has undergone a transformation, in particular, it has begun to be perceived positively, which is largely due to the influence of modern mass culture, universal literacy, and improvement of living conditions

Poetics of Path Chronotope in Yakut Heroic Epic (S.N. Karataev “Bogatyr Tong Saar”)

The article is devoted to the poetics of the path chronotope in the Yakut heroic epic. The relevance of the topic is due to the need for an in-depth study of the spatio-temporal organization of the path in the olonkho, in particular in the Vilyui epic tradition, to which the olonkho S.N. Karataev “Bogatyr Tong Saar” belongs. The novelty of the article lies in the fact that for the first time the poetics of the path chronotope in the Yakut epic is subjected to systemic analysis, and for the first time the peculiarities of the path chronotope in the Vilyui epic tradition are revealed. The author of the article comes to the conclusion that the chronotope of the path occupies the most important place not only in the chronotope of the olonkho, but in general in its plot-compositional organization. The structure of the path has been determined, consisting of three main parts: the departure of the hero on the path, the process of the path itself, the completion of the path (the return of the hero to his homeland), in which various plot motives are realized. Particular attention is paid to the plot-forming role of the path chronotope in the olonkho, its relationship with the system of characters, poetical and stylistic means. It has been established that the leading links of the poetics of the Yakut heroic epic have inextricable interconnections in solving the main ideological and aesthetic problems
