Packet loss concealment method based on hidden Markov model and decision tree for AMR-WB codec
Authors: Gueham Tarek , Merazka Fatiha
Published: April 2022

In this paper, we introduce hidden Markov model (HMM) based packet loss concealment (PLC) methods and discuss the impact of Markovian assumptions on the performance of these models. We also present a new PLC method, implemented on the G.722.2 codec, which relies on the HMM and Decision Tree (DT), namely HMDT architecture, to enhance the perceptual quality of Voice over Internet Protocol (VoIP) communications under severe packet loss conditions. The proposed method is a receiver-based model that tracks the statistical evolution of speech signals through HMM and uses the DT architecture to predict/estimate accurately the lost speech packets by exploiting the surrounding received speech packets. Objective and subjective metrics are used to evaluate the performance of the proposed method. Test results show that our proposed method enhances considerably the speech quality of the reconstructed speech signal and produces a more natural speech variation compared to conventional PLC methods.

Background
Bone protective effect of Si-Wu-Tang (SWT), a classical prescription of traditional Chinese medicine, is verified in clinical for thousand years. However, its mechanisms were still unclear. This study aims to investigate the molecular mechanism in ApoE -/- mice fed a high-fat diet combining network pharmacology and in-vivo experiments.
Methods
Femurs were collected from 6 ~ 8-week-old female ApoE-/- C57BL/6J mice (n = 12, 18–22 g) and their age-matched wild-type (WT) littermates C57BL/6J mice (n = 6, 18–20 g). They were divided into 3 groups: the control, SWT and model groups. Serum levels of high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were measured by the serum biochemical index. HE staining and immunohistochemistry analysis were performed to observe the pathological tissue structure and the location and expression level of targets from the pathway screened out by the network pharmacology method. Western blot (WB) and RT-PCR analyses were performed to detect the expression levels of target proteins and mRNAs, respectively.
Results
The results of the network pharmacology analysis showed that the mechanism of SWT in treating osteopenia was closely related to the oestrogen receptor (ER) signalling pathway. In vivo experiments indicated that, compared with control group, the distribution of bone trabeculae was sparse, and the bone density decreased. The levels of HDL-C and LDL- C in the serum of the model group increased significantly (p < 0.01). The expression of GPER, PI3K, AKT and BCL-2 in the bone tissue of the model group decreased, and P53, BAX, ERα and ERβ were upregulated. Compared with the model group, the body mass of the SWT group increased slowly. The bone density and the distributions of bone trabeculae both increased. The expression of ERα, ERβ, GPER, PI3K, AKT and BCL-2 increased. The decreased expression of apoptotic genes, including P53 and BAX, was observed.
Conclusion
SWT significantly reduced bone loss in ApoE -/- mice fed a high-fat diet. An important mechanism might be that SWT could activate the PI3K/AKT signalling pathway mediated by ER and then inhibit apoptosis-related proteins to exert bone protective effects.
Multiple UAVs Three-Dimensional Navigation Using a Hybrid Optimization Algorithm
Authors: Jain Upma , Dewangan Ram Kishan , Tiwari Shailendra , Prakash Jay
Published: April 2022

This paper aims to propose a hybrid approach for multiple UnmannedAerial Vehicle navigation. This is an NP-hard problem since the robots have to find the optimal safe path without colliding with other robots and obstacles in three-dimensional search space. The proposed approach enhances the exploration capabilities of the whale optimization algorithm and then hybrid this improved whale optimization algorithm with the sine cosine algorithm to improve the overall exploitation capabilities. The efficiency of the proposed hybrid approach is compared with other meta-heuristic algorithms for multi-UAV navigation. Results obtained through simulation ensure the validity of the proposed approach.

Published: April 2022

Background
Femoral neck fracture is a common fracture in orthopedic practice. This study aimed to compare the clinical outcomes between the femoral neck system and dynamic hip system blade for the treatment of femoral neck fracture in young patients.
Methods
This retrospective study included 43 and 52 patients who underwent treatment for femoral neck fracture with the femoral neck system and dynamic hip system blade, respectively, between August 2019 and February 2020. Operative indexes, including operation duration, blood loss, incision length, postoperative complications (femoral neck shortening, non-union, screw pull-out, femoral head necrosis), and Harris scale scores were recorded and analyzed.
Results
Compared to that with the dynamic hip system blade, the femoral neck system showed significantly less operation duration (femoral neck system vs dynamic hip system blade: 47.09 ± 9.19 vs 52.90 ± 9.64, P = 0.004), less blood loss (48.53 ± 10.69 vs 65.31 ± 17.91, P < 0.001), and shorter incision length (4.04 ± 0.43 vs 4.93 ± 0.53, P < 0.001). Femoral neck shortening was significantly lower with the femoral neck system than with the dynamic hip system blade (3.93 ± 2.40, n = 39 vs 5.22 ± 2.89, n = 44, P = 0.031). No statistical differences were observed between the two groups in nonunion, screw pull-out, and femoral head necrosis. In addition, the latest follow-up Harris scale score was significantly higher with the femoral neck system than with the dynamic hip system blade (92.3 ± 4.5 vs 89. 9 ± 4.9, P = 0.015).
Conclusion
The femoral neck system results in less trauma, less femoral neck shortening, and better hip joint function than the dynamic hip system blade for the treatment of femoral neck fracture in young patients.

In clinical practice a number of standardized neuropsychological tests have been designed to assess and monitor the neurocognitive status of patients with neurodegenerative diseases such as Alzheimer’s disease. Important research efforts have been devoted so far to the development of multivariate machine learning models that combine the different test indexes to predict the diagnosis and prognosis of cognitive decline with remarkable results. However, less attention has been devoted to the explainability of these models. In this work, we present a robust framework to (i) perform a threefold classification between healthy control subjects, individuals with cognitive impairment and subjects with dementia using different cognitive indexes and (ii) analyze the variability of the explainability SHAP values associated with the decisions taken by the predictive models. We demonstrate that the SHAP values can accurately characterize how each index affects a patients’ cognitive status. Furthermore, we show that a longitudinal analysis of SHAP values can provide effective information on Alzheimer’s disease progression.

The repertoire of coronavirus disease 2019 (COVID-19)-mediated adverse health outcomes has continued to expand in infected patients, including the susceptibility to developing long-COVID; however, the molecular underpinnings at the cellular level are poorly defined. In this study, we report that SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection triggers host cell genome instability by modulating the expression of molecules of DNA repair and mutagenic translesion synthesis. Further, SARS-CoV-2 infection causes genetic alterations, such as increased mutagenesis, telomere dysregulation, and elevated microsatellite instability (MSI). The MSI phenotype was coupled to reduced MLH1, MSH6, and MSH2 in infected cells. Strikingly, pre-treatment of cells with the REV1-targeting translesion DNA synthesis inhibitor, JH-RE-06, suppresses SARS-CoV-2 proliferation and dramatically represses the SARS-CoV-2-dependent genome instability. Mechanistically, JH-RE-06 treatment induces autophagy, which we hypothesize limits SARS-CoV-2 proliferation and, therefore, the hijacking of host-cell genome instability pathways. These results have implications for understanding the pathobiological consequences of COVID-19.

Authors: wang Lidong , zhang Honghai
Published: April 2022

Background
Mink fur is an important economic product, but the molecular mechanism of its color formation and fur development is still unclear. We used RNA-seq to analyze the skin transcriptome of young and adult minks with two different hair colors.
Result
The minks were made up of black adults (AB), white adults (AW), black juveniles (TB), and white juveniles (TW) (three each). We found that thirteen KRTAP genes and five signaling pathways (JAK-STAT signaling Pathway (cfa04630), Signaling pathways regulating pluripotency of stem cells (cfa04550), ECM-receptor interaction (cfa04512), Focal adhesion (cfa04510) and Ras signaling pathway (cfa04014)) were related to mink fur development through pair comparison and cross-screening among different subgroups. We also found a tyrosinase family (TYR, TYRP1, TYRP2) involved in mink hair color formation. The expression level of TYR in black young minks was higher than that in white young minks, but this phenomenon was not observed in adult minks.
Conclusion
Our study found significant differences in adult and juvenile mink skin transcriptome, which may shed light on the mechanism of mink fur development. At the same time, the skin transcriptome of black and white minks was also different, and the comparison was different by age, suggesting that the genes regulating hair color function in early childhood rather than adulthood. This study can provide molecular support for breeding mink coat color and improving fur quality.

The demand for eco-tourism is increasing in the world. The government plans to increase the attendance of protected areas. Due to this goalit is necessary to choose new 丨ocations and pay attention to the deve丨opmentstrat- egy of eco-tourism in the regions. There is a sufficient number of such territories in the Urals. These are national parks: Yugyd-Va, Pripyshminsky forests, Deer Streams, Taganay and all show a steady increase in attendance. Covid restrictions without doubt have negatively affected their visit, but they can be used for additional positioning of domestic tourism of an ecological orientation. To do this, one needs to know the potential consumer. They can be not only residents of neighboring territories, but also foreign tourists. The ways to solve the problems of ecological tourism development in the Urals are possible through: creating an accessible and comfortable environment for tourism development, improving the quality, safety and competitiveness of products formed in the field of ecological and adventure tourism, promoting tourist products in the domestic and international tourism markets. The mechanisms for solving the tasks set are seen in the creation of modern infrastructure, including on the territory of national parks with the involvement of private investors. It is necessary to ensure the systematic development of tourist facilities, offer a wide range of tours aimed at different target groups. At the moment, many territories are betting on the development of tourism. As the analysis of the programs has shown, they are not sufficiently systematic; they have overestimated the return on tourism. As a consequence, the issue of developing performance criteria for certain projects and the formation of different business models focused either on specialized enterprises or on several specialized or undeveloped territories are paramount. After all, there is a high risk of non-return of capital in tourism. This may stop potential investors. It would not be correct to assume that tourism can solve all the problems of the region, but taking into account current trends, it can be one of the points of economic growth and investment inflow

Authors:   MFA of Russia，Moscow, Belekova А.
Published: April 2022

Today UNESCO is the largest intellectual forum where the most important directions of the world community development in the humanitarian sphere are being discussed and implemented. In this very body，beyond politically-charged confrontations and on the basis of the principle of consensus priority，a collective search for answers to the most important common human problems is carried out. In this context the UNESCO mission can hardly be overestimated. National Commissions for UNESCO in their turn are the essential link between the Member-States and the Organization. Political turbulence and complex contradictions of a number of leading countries of the world nowadays impose on UNESCO the priority task to model a new matrix of intellectual cooperation and demonstrate the urgent need to develop innovative mechanisms for the implementation of the main UNESCO goals and ideals. In this regard it is extremely important to get a more complete picture of the practical contribution of the National Commissions to the UNESCO activities on the example of the Russian Federation and to present recommendations that would have a positive and beneficial effect on the overall activities of the network. The author has made an attempt to systematically analyze the activities of this specialized entity of Russia to promote and popularize the UNESCO principles and values. A projection of the most important vectors is presented in the research. The most innovative mechanisms for the UNESCO programs and applied projects have been identified. The author has analyzed the possibilities of capacity-building of the National Commission. Some aspects related to its strategic objectives are reflected in the research. Particular attention is dedicated to the task of creating new pillars of the National Commission of the Russian Federation for UNESCO in the regions of Russia

Recently, due to the clearly expressed tendency to involve poor ores with a low content of a valuable component in the exploitation, heap leaching technology has been increasingly used. As a rule, it is sold on small reserves and sizes of ore deposits. For example, in the Transbaikal Territory, the number of developed gold-bearing de posits and potentially suitable for the development by heap leaching technology of a valuable component today is about 31. Moreover, deposits, as a rule, are located on the territory represented by frozen and permafrost soils. They are characterized by harsh climatic conditions and low-snow winters. One of the promising areas of the research is the method of block modeling, which, with the development of information technology, acquires special significance and is aimed at solving the urgent problem of three-dimensional modeling. Its main advantage is that it allows you to quantify the spatial distribution of factors, as well as the dynamics of their changes over time. The object of research is an ore stack of a technogenic deposit. The subject of the study is mathematical modeling of gold heap leaching. The purpose of the study is to develop a method for block modeling of gold heap leaching in an ore stack and a methodology for its implementation. The research methodology is the use of the regularities of filtration and physico-chemical seepage of leaching solutions through the porous medium of the ore stack. Research methods are the following: physical and mathematical methods modeling of heap leaching processes; use of statistical methods to identify patterns of spatial distribution of factors affecting the heap leaching process; use of software products (geoinformation systems) for data visualization
PRIMARIES AS A FORM OF POLITICAL PARTICIPATION OF PARTIES
Authors:   Transbaikal State University, Chita, Zimina N.
Published: April 2022

The article is devoted to the procedure of conducting primaries - preliminary intraparty voting in Russia and participation in primaries of political parties. The subject of the article “Primaries as a form of political participation of parties” is primaries. The purpose of the article is to study the procedure of primaries as a form of political participation of political parties. The article presents various methods, such as analysis, comparative method, survey, which to a greater extent make it possible to define the conceptual apparatus, to conduct a comprehensive analysis of primaries. Primaries are used in the electoral systems of the USA, Italy, Russia and other countries. The history of primaries in Russia dates back to 2000, and the United Russia party held its first primaries in 2007 in order to determine the party's candidates for the elections. It can be noted that despite the rather long existence of primaries in the Russian political process, there is still no single legal interpretation of the primaries procedure. Today, attempts are being made in Russia to institutionalize primaries as a form of political and legal participation of parties in electoral procedures, which is confirmed by the data of recent electoral campaigns. Primaries are firmly included in the electoral process as pre-election intra-party voting, which allows forming lists of participants in the elections from a political party at the preliminary stage of the elections. In Russia, with its imitation democracy, primaries in “systemic” parties can also be called imitation. In non-systemic opposition blocs, we can sometimes observe honest primaries; these parties have no chance of getting into power even at the regional level, because primaries are actively used only by United Russia. As a result of the work, the author comes to the conclusion that the Russian version of the primaries is far from perfect and needs careful refinement of the legal and technological aspects of the primaries and requires rethinking the true objectives of the procedure, which was projected from the American political reality to the unprepared Russian electoral procedure. The results of the study can be applied when conducting primaries by political parties and their regional branches in the conditions of the Transbaikal Territory.

There can be no state sovereignty without information sovereignty. The Chinese Government understands this well and during the COVID-19 pandemic, when the whole world “went online”，adopted several laws designed to regulate the country's information policy in the media sphere. At the time of writing, China has a new legislation in the field of information security. The most crucial laws in information and cyber sphere are the Law “On Data Security”，“On Personal Data Protection”，and the Law “On Cyberspace”，the first two of which are developed to supplement and improve the application of the Law “On Cybersecurity” adopted in 2017. However, the adoption of these laws entailed a number of problems for Chinese tech-goliaths and caused a wave of international criticism. This article examines the key provisions of the new set of China's legal framework in the field of information security and analyzes the prospects for its further development. Materials and methods. Formal legal methods of analyzing Chinese legislation in the in formation and cyber spheres are involved, scientific and general scientific methods of cognition of the specifics of China's national legislation in the field of ensuring the protection of national and information security and state sovereignty are usedin this paper. Results of the study. The new information legislation of China traces the same vector of state policy aimed at protecting national sovereignty by ensuring a data security system regulated by the Chinese Government and their localization on the territory of the country. China considers the data accumulated by private companies as a national asset, the use of which should be carried out or restricted in accordance with Chinese laws. However, most of the law needs to supplement and expand some terms due to the threat of legal uncertainty and the creation of a legal vacuum for manipulation
ACCURACY OF SATELLITE ESTIMATION OF SURFACE TEMPERATURE OF HETEROGENEOUS URBANIZED AREAS
Authors:   Institute of Space Research of Natural Resources of the National Aero Agency, Baku space, Mammadova E.
Published: April 2022

Temperatures in urban areas are always higher than in rural areas, “urban heat islands” noticeably affect the urban climate, which puts the theme under discussion in the category of acute environmental problems. The author suggests a possibility of accurate satellite-based estimation of surface temperature of heterogeneous urbanized areas. The object of the study is surfaces of urbanized areas. The subject of the study is satellite temperature estimation of “urban heat islands”. The aim of the study is to scientifically substantiate the probability of an accurate satellite assessment of surface temperature of heterogeneous urbanized areas. The realization of the aim involves solving a number of tasks, the main ones of which are: - to reveal the dependence of the depth of the carried out correction of the emissivity variability influence on the measured value of the degree and character of emissivity change from the wavelength; - to consider the emissivity properties of new and old asphalt pavement. The research methodology is presented by the ecological approach and structural-functional approach. The aim of the study and its objectives has determined the need to use the following methods: analysis, synthesis, induction, deduction, comparison, explanation. The task of increasing the accuracy of remote sensing of heat islands appearing in urbanized areas by taking into account the emissivity index spectral dependence of objects on the surface of the ground cover on the wavelength has been formulated and solved. It is determined that the optimum is the inverse dependence of the emissivity coefficient on wavelength. Emission properties of new and old asphalt pavement have been considered, and on the basis of the analysis the author has made a conclusion about the importance of taking into account the temperature of such a pavement. It has been found that if, according to the Planck curve family, asphalt pavement emits at an appropriate temperature in the 9…11 pm range at the maximum energy, the requirement for the correction may weaken, and, consequently, the error due to the failure to consider the influence of spectral variability in emissivity may diminish

Published: April 2022

The subject of the study is identification of the content peculiarities and its impact on users of the social network Instagram, based on the case the State Duma members from Kuzbass. The purpose of the study is to analyze the qualitative parameters of the content created in the Instagram social network by members of the State Duma from Kuzbass. The methodological basis of the study was formed with M. CasteNs5 network society approach and J.-F. Lyotard's concept of the pluralism of truths. The use of these approaches has made it possible to consider Internet communications in social networks as an unpredictable source of information from the standpoint of users' assessment. To systematize data and analyze information “bursts” in the social network, a specialized Feedspy software has been applied. Subsequently, using the method of content analysis, posts and comments have been analyzed focusing on the cases of Anton Gorelkin and Vyacheslav Petrov, politicians-members of the State Duma from Kuzbass, who are the most active on Instagram. The chronological framework of the study covered the electoral campaign period from April to September 2021. In considering the term Internet communications, the paper identifies two existing communication models - vertical and horizontal. The modern system of communications in social networks corresponds to a horizontal model of communications based on the principle of subject-to-subject relations. As a definition of Internet communication, the approach of J. Arquilla and D. Ronfeldt is used, who define communication as a structure that promotes the transfer of information and the formation of values. It has been found that news, image and communication content are the most popular content types among the parliament members. A. Gorelkin uses more diverse types of content in his social network and actively builds communication through comments, while parliament member V. Petrov builds communication in a completely different way. Against the background of a very “calm” election campaign, as evidenced by the subject matter of the posts and the presence of comments from fake pages, there is a very high proportion of positive comments

SYSTEMS OF JOINT ENTREPRENEURSHIP IN THE REGIONS OF RUSSIA: STRUCTURAL, QUANTITATIVE AND DYNAMIC ANALYSIS
Authors:   Rostov State University of Economics，Rostov-on-Don, Tertishnikova M.
Published: April 2022

Any state strives to invest not only its own funds in the development of its economy, but also to attract foreign investment. This makes it possible to open new production facilities, as well as attract advanced technologies and experience of foreign specialists. This article discusses the problems of the development of joint entrepreneurship systems in the Russian Federation at the latest historical stage. The subject of the study is the organizational and economic relations that have arisen and developed in the course of the activities of joint ventures with the participation of foreign capital. The purpose of the study is to determine the current situation of joint entrepreneurship in Russia. To achieve this goal, a structural and quantitative analysis of the indicators of the development of joint entrepreneurship in macro-regions (federal districts) was carried out Interregional and intraregional imbalances have been identified, factors negatively affecting the development of joint forms of doing business in the country have been identified. As a result, based on the data obtained, it was revealed that during the period under review there was a decrease in the number of joint ventures on the territory of the Russian Federation. Foreign investors are afraid to invest their funds in long-term investments due to the unstable economic situation in the country. The presence of sanctions also does not add to the investment attractiveness. An analysis of the activity of joint entrepreneurshi p by region showed that only a few have developed programs for the development of foreign capital participation in joint ventures. The rest are practically not developing in this direction. As a result of the work performed, the author formulated measures to support and stimulate the development of joint entrepreneurship in the country as a whole and in certain regions of Russia in particular

Bell, M. McLuhan, M. Castells), mass communication theory (H. Blumer, N. Postman, 巳. Skinner, G. Gerbner and others), as well as Russian scientists G. L. Akopov, I. A. Bykov, and S. V. Volodenkov. The author notes that the works of contemporary experts focus, to a greater extent, on conducting regional studies on social networks. It was found that there are fundamental differences between the content in social accounts of the political party leaders and the governor of Kuzbass. It is shown that, unlike the governor's account, where users can ask their urgent questions in the comments and receive answers, the content of the party leaders is more entertaining. The posts of politicians representing political parties are not opinion exchange platforms and are not aimed at solving topical social and economic issues. The main task of comments in the posts of party leaders is to maintain interest in their persons (by posting personality-focused content), rather than in the professional political activities of a politician.

Research methods are the following: methods of system, situational and comparative analysis were used in the work. As a result of the study, the high importance of the state's participation in the development of technoparks as a key subject of innovation activity is determined. The necessity of public-private partnership is substantiated, which determines the vector of sectoral development based on the interest of leading enterprises in regions of various specialization. The limitations of sustainable integration of technoparks are determined due to the inconsistency of traditional approaches to managing these structures, the need for fundamentally new management models in difficult situational conditions.
