The conference is characterized by urgency, informative, debatable, creative collaboration etc., promotes new ideas, knowledge, and discoveries in the field.
An important thing in format of conference is a senior research co-generation of talented young people (students work on scientific articles under the guidance of Ph.D’s, performances of students for authoritative audience), exchange of experience, ‘master classes’ in the flesh
To the question of action on the rods lying on elastic foundation, inertial load with a variable speed of its movement
No full textA method for calculating the rods on elastic foundation under the inertial load action when it moves at a variable speed is proposed. Test problems about a force or load movement with variable speeds along a hinged beam and about the movement with a high-speed railway car deceleration along a track section modeled by a hinged supported beam of great length on an elastic foundation are considered. The selection of the elastic foundation material of the rail track determines the dynamics of the high-speed railway car in different modes of its movement. To construct the methodology, the previously proposed by the author of the article solutions are used: a step-by-step procedure for solving the problems of unsteady dynamics of structures and the method of “nodal accelerations” to take into account the action on structures of a moving inertial load
Small immunological clocks identified by deep learning and gradient boosting
No full textBackground: The aging process affects all systems of the human body, and the observed increase in inflammatory components affecting the immune system in old age can lead to the development of age-associated diseases and systemic inflammation. Results: We propose a small clock model SImAge based on a limited number of immunological biomarkers. To regress the chronological age from cytokine data, we first use a baseline Elastic Net model, gradient-boosted decision trees models, and several deep neural network architectures. For the full dataset of 46 immunological parameters, DANet, SAINT, FT-Transformer and TabNet models showed the best results for the test dataset. Dimensionality reduction of these models with SHAP values revealed the 10 most age-associated immunological parameters, taken to construct the SImAge small immunological clock. The best result of the SImAge model shown by the FT-Transformer deep neural network model has mean absolute error of 6.94 years and Pearson ρ = 0.939 on the independent test dataset. Explainable artificial intelligence methods allow for explaining the model solution for each individual participant. Conclusions: We developed an approach to construct a model of immunological age based on just 10 immunological parameters, coined SImAge, for which the FT-Transformer deep neural network model had proved to be the best choice. The model shows competitive results compared to the published studies on immunological profiles, and takes a smaller number of features as an input. Neural network architectures outperformed gradient-boosted decision trees, and can be recommended in the further analysis of immunological profiles
Prospects for Creating a Reserve Currency by the Shanghai Cooperation Organization Countries
No full textThe purpose of this study is to clarify the prospects for the creation of a new reserve currency by the (Shanghai Cooperation Organization (SCO) countries to reduce foreign exchange costs in trade transactions, to strengthen integration processes in the Eurasian space, to increase the investment potential of developing Asian countries and to stimulate sustainable economic growth. The paper presents the results of mathematical modeling of the optimal portfolio structure of collateral assets with the possible issuance of a new reserve currency by the SCO countries. The article concludes that currently the best reserve assets that have been analyzed are the Chinese yuan, Indian rupee and gold. The expected return of the new reserve currency does not depend on fluctuations in the global foreign exchange market, and its calculated risk (standard deviation of return) turned out to be lower than the risk of fluctuations in the value of the yuan and gold. The article concludes that gold is the best collateral asset, as it has a stable positive yield, constant purchasing power and a fair value that is 4 times higher than the market value. It is proposed to issue a new reserve currency in the form of stablecoins so that it incorporates all the best properties of cryptocurrencies and fiat mone
Money Field Theory: in Pursuit of Formalism
No full textThe article explores the possibility of interaction between financial and industrial sectors of an economy via such a new economic notion as a pervasive money field, which is used to pin down the elusive entropy of financial markets. The theory of a field originally comes from physics and we show the way it can be applied to economic reality. The implementation makes possible not only to reunite separate channels of monetary transmission mechanism into a single mechanism, but it also provides a new glimpse at the formalized mechanism of macroeconomic monetary relationship
Artificial Intelligence and Law: Theoretical and Legal Features
No full textArtificial Intelligence (AI) has become one of the most transformative technological phenomena in the modern digital era. This article raises fundamental theoretical and legal issues related to the classification and regulation of artificial intelligence. This study aims to examine in depth the concept, characteristics, legal nature, scope of application, and regulatory framework of artificial intelligence from an information law perspective. This study uses a qualitative method with a literature approach and a legal approach (normative juridical), where data is obtained through a literature review of various scientific literature, laws and regulations, legal documents, and relevant academic articles. In this study, the author explores various approaches in defining the concept of AI, as well as examining its legal regulations in various jurisdictions. One important finding shows that artificial intelligence law can be categorized as a legal institution within the information law framework. In addition, the issue of legal responsibility for AI actions is an important highlight, considering that artificial intelligence can act autonomously but does not yet have a clear legal subject. This article also describes the use of AI in various fields such as health, transportation, and finance, considering each sector\u27s specific characteristics. While the benefits offered, such as efficiency and automation, the article also highlights the potential risks inherent, including privacy violations and algorithmic bias. Overall, this research provides conceptual and normative insights into the legal challenges and opportunities in the development and application of AI

Age-related DNA methylation changes are sex-specific: a comprehensive assessment
No full textThe existence of a sex gap in human health and longevity has been widely documented. Autosomal DNA methylation differences between males and females have been reported, but so far few studies have investigated if DNA methylation is differently affected by aging in males and females. We performed a meta-analysis of 4 large whole blood datasets, comparing 4 aspects of epigenetic age-dependent remodeling between the two sexes: differential methylation, variability, epimutations and entropy. We reported that a large fraction (43%) of sex-associated probes undergoes age-associated DNA methylation changes, and that a limited number of probes show age-by-sex interaction. We experimentally validated 2 regions mapping in FIGN and PRR4 genes and showed sex-specific deviations of their methylation patterns in models of decelerated (centenarians) and accelerated (Down syndrome) aging. While we did not find sex differences in the age-associated increase in epimutations and entropy, we showed that the number of probes having an age-related increase in methylation variability is 15 times higher in males compared to females. Our results can offer new epigenetic tools to study the interaction between aging and sex and can pave the way to the identification of molecular triggers of sex differences in longevity and age-related diseases prevalence

Парамагнитный резонанс в электрон-примесных системах
No full textThe equation for the magnetization is obtained on the basis of the kinetic equation for an isotropic distribution function of electrons scattering on massive impurity centers in the presence of magnetic and electric fields. The analytical solution of the Cauchy problem for a given initial distribution of the magnetization under conditions of paramagnetic resonance is obtained. The estimated dynamic frequency shift of the forced precession has nonlocal and nonlinear dependence on the nonuniform distribution of the initial magnetization. The dynamic frequency shift of the free precession has only nonlocal character. Time and space dependence of the internal field is obtained. All results are expressed in terms of the initial distribution of the magnetization without specifying its functional form and in terms of the propagation function. These results may be used for analysis of spin diffusion in natural and manmade materials and also in magnetometry.The author thanks Prof. S.V. Peletminskii for the interest in the research and for useful discussion
