Life has offered humanity a unique experiment of experience a real threat and an unprecedented reaction to in the form of self-isolation. Media communication has a crucial role in this situation.

The research focuses on the analysis of the media sphere dynamics during COVID-19 pandemic on the example of popular local news website. Data on publication activity, views and comments were collected from January 22 to July 19. Qualitative analysis of comments revealed high user aggression, especially during the first months of coronavirus pandemic. Also, three groups of commentators were identified which differ in their attitudes towards the problem of coronavirus.

An unexpected and paradoxical scene is observed. As the epidemiologic situation worsens, journalists write less about COVID-19 and users demonstrate less interest and emotions in this topic too. It was revealed that user reactions are mostly caused by messages about lockdown, bans and restrictive measures rather than on the epidemiologic reports and details. The article discusses two periods which are characterized by different behavior if users and journalists. At first, the unique uncertainty situation generates great interest and emotional response to information about coronavirus. So, users and authors are guided by news about pandemic from Europe and China. Later understanding of possible risks displaces interest in the topic and reduce the degree of emotions. Moscow context becomes a guide in perception of pandemic as a stressful situation. In none of these periods the local epidemiological situation didn`t play a crucial role in determining of the reaction of the media sphere.
This paper is an overview of an international research and practice workshop 'Rock Art: Methods and Techniques of Documenting' which took place in July of 2018 at Shalabolino site as part of work of the Minusinsk Rock Art Research Expedition of IAET SB RAS.

We estimate effectiveness of the proposed format of a scientific event and also describe modern approaches to documenting and analyzing rock art (engravings and paintings) at open air sites.
The paper deals with initial-boundary value problems for the linear wave equation whose solutions stabilize to zero in a finite time.

To show this for C2, we prove a smoothing result implying that the solutions to the perturbed problems become eventually C2-smooth for any H1 × L2-initial data.

We prove that problems in this class remain exponentially stable in L2 as well as in C2 under small bounded perturbations of the wave operator.
The ongoing COVID-19 pandemic has highlighted significant gaps in human protection from infection. There is a real and fairly high probability of new infections that pose a danger to humans.

To combat (prevention and treatment) this kind of infections, new types of drugs are needed, which differ in their mechanism of action from existing antimicrobial agents and vaccines, and thus complement them. These drugs should have complex universal activity against pathogens, regardless of their type (bacteria, viruses, fungi, protozoa) and, in general, increase the resistance of the macroorganism to infection by pathogenic agents, stimulate nonspecific immunity, both general and local. In this regard, preparations of nanostructured silver are promising. The properties of silver nanoparticles depend on their structure, shape, size, morphology, ligand environment and preparation method. Argovit represents nanosilver formulation with optimized biochemical and toxicological characteristics.

Argovit effectiveness for combating infectious pathogens in various fields of medicine was shown for: intestinal infections of various etiologies; acute respiratory viral infections and associated bacterial complications; purulent surgery, diabetic foot; drug resistant forms of tuberculosis; viral infections caused by both DNA and RNA viruses. In the clinic, argovit effectiveness in protection from coronavirus infection and for treatment of the early stages of COVID-19 disease on volunteers was shown.
In this paper we describe an approach to building low latency shared network storage based on multi-layered unification and results of testing a prototype of this type of storage.
To accompany boron neutron capture therapy for cancerous tumours, there has been an optimised ICP-AES method for boron determination in animals' organs tissues.This technique is characterised by its universalism.The approach comprises preliminary acid decomposition at high temperatures and pressure (if necessary), ICP-AES boron determination in the gained solutions analysing comparative samples basing on a single element solution.Its validity is proved by the spike experiment and mass sample variation test.The ICP-AES method is used during the evaluation of BPA and BSH accumulation in organs and tissues when intravenously injecting U87 glioblastoma medication to SCID mice of SPF-status.

N‐type microcrystalline silicon carbide (μc‐SiC:H(n)) is a wide bandgap material that is very promising for the use on the front side of crystalline silicon (c‐Si) solar cells. It offers a high optical transparency and a suitable refractive index that reduces parasitic absorption and reflection losses, respectively. In this work, we investigate the potential of hot wire chemical vapor deposition (HWCVD)–grown μc‐SiC:H(n) for c‐Si solar cells with interdigitated back contacts (IBC). We demonstrate outstanding passivation quality of μc‐SiC:H(n) on tunnel oxide (SiO 2 )–passivated c‐Si with an implied open‐circuit voltage of 742 mV and a saturation current density of 3.6 fA/cm 2 . This excellent passivation quality is achieved directly after the HWCVD deposition of μc‐SiC:H(n) at 250°C heater temperature without any further treatments like recrystallization or hydrogenation. Additionally, we developed magnesium fluoride (MgF 2 )/silicon nitride (SiN x :H)/silicon carbide antireflection coatings that reduce optical losses on the front side to only 0.47 mA/cm 2 with MgF 2 /SiN x :H/μc‐SiC:H(n) and 0.62 mA/cm 2 with MgF 2 /μc‐SiC:H(n). Finally, calculations with Sentaurus TCAD simulation using MgF 2 /μc‐SiC:H(n)/SiO 2 /c‐Si as front side layer stack in an IBC solar cell reveal a short‐circuit current density of 42.2 mA/cm 2 , an open‐circuit voltage of 738 mV, a fill factor of 85.2% and a maximum power conversion efficiency of 26.6%.
Background.Trabecular bone score obtained by lumbar spine Dual-energy X-ray Absorptiometry is a novel and insufficiently explored instrument of accessing trabecular bone quality. One of its promising applications is early diagnostics of osteoporosis (OP) before fragility fractures appear. Meanwhile most of systemic inflammatory rheumatic diseases affect bone tissue either directly and indirectly by glucocorticoids consumption. Both factors potentiate OP development and can influence the trabecular bone score. Aimsto evaluate the possibilities of trabecular bone score using in rheumatology. Materials and Methods.Data analysis of domestic and foreign scientific publications. Results and Discussion.Authors of analyzed publications note stable association of low trabecular bone score with vertebral fractures, its correlation with local inflammatory markers in lumbar spine and ankylosing spondylitis structural progression. In most studies trabecular bone score do not have association with systemic inflammatory activity and treatment. Conclusion. Trabecular bone score is effective in OP diagnostics in rheumatic patients, evaluation of local inflammatory activity in the lumbar spine and structural progression of ankylosing spondylitis.
From 2011 to 2014, the BESIII experiment collected about 5 fb−1 data at center-of-mass energies around 4 GeV for the studies of the charmonium-like and higher excited charmonium states.

By analyzing the di-muon process e+e− → γISR/FSRμ+μ−, the center-of-mass energies of the data samples are measured with a precision of 0.8 MeV.

The center-of-mass energy is found to be stable for most of the time during data taking.
One of the most difficult tasks in the field of data mining is the development of universal tools for the analysis of texts written in the literary and business styles. A popular path in the development of algorithms for processing text document corpus is the use of machine learning methods that allow one to solve NLP (natural language processing) tasks. The basis for research in the field of natural language processing is to be found in the following factors: the specificity of the structure of literary and business style texts (all of which requires the formation of separate datasets and, in the case of machine learning methods, the additional feature selection) and the lack of complete systems of mass processing of text documents for the Russian language (in relation to the scientific community-in the commercial environment, there are some systems of smaller scale, which are solving highly specialized tasks, for example, the definition of the tonality of the text). The aim of the current study is to design and further develop the structure of a text document corpus processing system. The design took into account the requirements for large-scale systems: modularity, the ability to scale components, the conditional independence of components. The system we designed is a set of components, each of which is formed and used in the form of Docker-containers. The levels of the system are: the data processing level, the data storage level, the visualization and management of the results of data processing (visualization and management level). At the data processing level, the text documents (for example, news events) are collected (scrapped) and further processed using an ensemble of machine learning methods, each of which is implemented in the system as a separate Airflow-task. The results are placed for storage in a relational database; ElasticSearch is used to increase the speed of data search (more than 1 million units). The visualization of statistics which is obtained as a result of the algorithms is carried out using the Plotly plugin. The administration and the viewing of processed texts are available through a web-interface using the Django framework. The general scheme of the interaction of components is organized on the principle of ETL (extract, transform, load). Currently the system is used to analyze the corpus of news texts in order to identify information of a destructive nature. In the future, we expect to improve the system and to publish the components in the open repository GitHub for access by the scientific community.
The study on the signs of socio-economic constitutionalism addresses only certain aspects of this broad issue. The article says that the Constitution of the Russian Federation lays down the potential of a socially oriented economy, examines the relationship of the social and economic foundations of the constitutional system with the foundations of the socio-economic status of the individual and the problems of the country's economic development.

The scientific novelty of the study lies in the fact that the significance of constitutional values in the context of socioeconomic constitutionalism during the economic crisis is indicated, a correlation is established between the effective development of a socially-oriented economy and the implementation of constitutional norms that enshrine the principles and guarantees of socio-economic rights as basic guidelines, not fully implemented.

The scientific result of the study was the proposal of the need to develop and implement a state standard of social well-being. In connection with the use of such a standard, law enforcement practice may in the future contribute to positive shifts in Russian socio-economic constitutionalism in the context of the formation of answers to the challenges of globalization.
The TAIGA-IACTs are part of the hybrid TAIGA experimental complex, located near lake Baikal in Tunka valley, Siberia, Russia. The telescopes have segmented mirrors in Davis-Cotton design with the reflector diameter of 4.3 m and an imaging camera with PMTs in its focus to detect nanosecond flashes of Cherenkov light from EAS. The TAIGA-IACTs are operating in wobble mode. Their operation requires high pointing and tracking accuracy, especially important for long exposure times.

The telescope positioning system consists of steppers motors, 17-bit angular encoders and a CCD camera for accurate monitoring of the telescope pointing by stars in its field of view and related calibration procedures. The telescope is controlled by using the custom software based on the EPICS (Experimental Physics and Industrial Control System) package.

This report presents an overview of the TAIGA-IACT control and monitoring software, pointing accuracy and the relevant calibration procedures.
Due to the photothermal conversion effect induced by laser radiation, MWCNTs can enhance thermal destruction and removal of the polymer from the composite surface. It was found that in pristine composites only a small part of MWCNTs is located directly on the surface of the film, which is associated with the high work of polymer adhesion to the nanotube surface and the surface tension forces of the polymer matrix melt.

In this article, we investigate the use of laser processing to create effective surface contacts on multi-wall carbon nanotube (MWCNT)/polyethylene composites. The structure of pristine and lasermodified composites is characterized by Raman spectroscopy, optical and scanning electron microscopy. Scanning electron microscopy (SEM) and Raman scattering demonstrate that in the surface contacts formed under the action of laser radiation, the polymer matrix is removed from the near-surface layer. The presence of MWCNTs with an unchanged structure and a small amount of amorphous carbon material was confirmed by Raman spectroscopy. The conductivity of pristine and modified composites was characterized by a series of current-voltage characteristic measurements with the through-plane 4-point probe.

It was found that laser treatment of the composite surface leads to an increase in the measured volume conductivity by 1-2 orders of magnitude, depending on the content of MWCNTs. At the same time, the removal of the near-surface layer of the polymer by laser treatment makes it possible to reduce the contribution of the contact resistance to the resistance of the composite measured by 2-point probe from 55-77 to 0.18-5.3% for composites with an MWCNT content of 2.5-4 wt%.
The present paper reports on the investigation of fuel-rich and fuel-lean turbulent combustion in a high-swirl jet. The jet flow was featured by a breakdown of the vortex core, presence of the central recirculation zone and intensive precession of the flow. The measurements were performed by the stereo PIV, OH PLIF and HCHO PLIF techniques, simultaneously. Fluorescence of OH* in the flame and combustion products was excited via transition in the (1,0) vibrational band of the A2Σ+ – X2Π electronic system. The fluorescence was detected in the spectral range of 305-320 nm. In the case of HCHO PLIF measurements the A-X transition was excited. The jet Reynolds number was fixed as 5 000 (the bulk velocity was U0 = 5 m/s). Three cases of the equivalence ratio ϕ of methane/air mixture issued from the nozzle were considered 0.7, 1.4 and 2.5. In all cases the flame front was subjected to deformations due to large-scale vortices, which rolled-up in the inner (around the central recirculation zone) and outer (between the annular jet core and surrounding air) mixing layers.
The article analyzes the key trends in consolidation and restructuring defense sector assets developed in the XXI century, i.e. the creation of vertically integrated structures in accordance with the decrees of the President of the Russian Federation; the inclusion of financially disadvantaged enterprises in concerns and state corporations, their subsequent financial recovery within the framework of integrated structures; the specifics of integration strategies of the leading defense industry holdings by the example of Rostec group, Almaz-Antey concern, USC group, and Roscosmos group. The paper gives the motives of the Russian defense companies for non-organic growth strategies and restructuring according to the state priorities. The article proposes the approaches to financial recovery of defense enterprises, given the preparation of profound amendments to the bankruptcy law; maintaining a favorable institutional climate in the M&A market for defense enterprises, etc. According to the authors, dominant leaders will continue to participate in the implementation of state programs that will require certain concentration of both efforts and capital as well as assets redistribution of a particular state Corporation.
This chapter focuses on critical problems of the nature and genesis of human sexuality: the classic concept of different sexual strategies of men and women, primordiality and naturalness of monogamy, the disinterestedness of women in sex, evolutionary “side effect” of female orgasm. We present and discuss inescapability of adultery, the diversity of sexual relations in pre-state societies, the revealed mechanisms of competition and selectivity in the anatomy and physiology of male and female reproductive organs. The modern versions of the adaptive significance, functions of the female orgasm deserve particular attention. Neither “egoistic” explanations (retention of a partner and “hunting” for good genes) nor esthetic ones (self-value of pleasure) are sufficient. The evolutionary hypothesis explains the genesis of emotional and sexual syncretism in women and the “cleavage” (dualism) of male sexuality. Women’s feelings toward men come from girls’ love and commitment to fathers and older men as protectors. Their feelings toward mothers remain intact: close relationships and at least partial identification with mothers remain in the majority. In boys, the original love for mothers inevitably suffers a crisis both in phylogeny through sexual selection, masculine culture, and in ontogeny through negative reinforcement.
By means of in situ ultrahigh vacuum reflection electron microscopy, the nucleation of vacancy islands on wide terraces of the Si(100) surface is investigated.

The temperature dependence of the displacement of a vacancy island nucleation center is determined in the process of heating a sample with a dc electric current. On the basis of a theoretical model, the effective electric charge of addimers is estimated in the direction across dimer rows of the surface.

The effective charge has a positive sign and does not exceed 15 units of the elementary charge in the temperature range of 1020–1120°C.
Nanowires with helical surface states represent key prerequisites for observing and exploiting phase-coherent topological conductance phenomena, such as spin-momentum locked quantum transport or topological superconductivity. We demonstrate in a joint experimental and theoretical study that gated nanowires fabricated from high-mobility strained HgTe, known as a bulk topological insulator, indeed preserve the topological nature of the surface states, that moreover extend phase-coherently across the entire wire geometry. The phase-coherence lengths are enhanced up to $5\ensuremath{\mu}\mathrm{m}$ when tuning the wires into the bulk gap, so as to single out topological transport. The nanowires exhibit distinct conductance oscillations, both as a function of the flux due to an axial magnetic field and of a gate voltage. The observed $h/e$-periodic Aharonov-Bohm-type modulations indicate surface-mediated quasiballistic transport. Furthermore, an in-depth analysis of the scaling of the observed gate-dependent conductance oscillations reveals the topological nature of these surface states. To this end we combined numerical tight-binding calculations of the quantum magnetoconductance with simulations of the electrostatics, accounting for the gate-induced inhomogeneous charge carrier densities around the wires. We find that helical transport prevails even for strongly inhomogeneous gating and is governed by flux-sensitive high-angular momentum surface states that extend around the entire wire circumference.
We consider the bicriteria asymmetric traveling salesman problem (bi-ATSP).The optimal solution to a multicriteria problem is usually supposed to be the Pareto set, which is rather wide in real-world problems.For the first time, we apply to the bi-ATSP the axiomatic approach of the Pareto set reduction proposed by V. Noghin.We identify series of "quanta of information" that guarantee the reduction of the Pareto set for particular cases of the bi-ATSP.An approximation of the Pareto set to the bi-ATSP is constructed by a new multiobjective genetic algorithm.The experimental evaluation carried out in this paper shows the degree of reduction of the Pareto set approximation for various "quanta of information" and various structures of the bi-ATSP instances generated randomly or from TSPLIB problems.
The current paper is concerned with linguocultural (ethnolinguistic) analysis of australianisms as culture specific words which are either not found in British English (the mother tongue) or are different from their British counterparts to some extent. The main research question was to identify the key lexemes of this type and establish correlation between them and Australian values (the national identity) as well as ethnostereotypes in modern Australian society. The novelty of the approach to studying these lexical units is in looking at them in terms of their functioning in speech and pragmatics based on the most sensitive to social change and dynamic type of discourse – the media (The material was drawn for the national papers “The Daily Telegraph, Australia” and “The Australian” over the past decade). By means of the random selection method, definitional and contextual analyses six key concepts have been identified (fair go, fair dinkum, larrikin, battler, bludger, (hard) yakka – the last word being aboriginal) and their place in the national identity structure defined. Also, we found some differences in how the same australianisms were presented and ranked in either paper manifesting certain values (for example, battler) or anti-values (for example, bludger) depending on the editorial board’s opinion and/or the content. For instance, “The Daily Telegraph” clearly highlighted the idea of justice (e.g. fair go, fair dinkum), while “The Autralian” put more focus on praising the stubbornness of Australians in the struggle against various obstacles (e.g. battler). References to the boisterous (larrikin) nature of Australians were somewhat more frequent “The Daily Telegraph”, although this concept was quite important for both newspapers. One of the most interesting results we got was a shift in connotations of several australianisms. Thus, it was shown that some words (for example, larrikin), originally having a negative meaning, with time may become positively connoted, characterising a certain previously disapproved type of person / behavior as normal. The study can be continued to include more words of this type, especially aboriginal ones which are already used in media and call for ethnolinguistic (linguocultural) interpretation by researchers.
