Carotid atherosclerosis (CA) and, especially, carotid artery stenosis (CAS), are associated with a high risk of cardiovascular events in subjects with type 2 diabetes (T2D).

In this study, we aimed to identify risk factors and biomarkers of subclinical CA and CAS in T2D individuals. High-resolution ultrasonography of carotid arteries was performed in 389 patients. Ninety-five clinical parameters were evaluated, including diabetic complications and comorbidities; antihyperglycemic, hypolipidemic, and antihypertensive therapy; indices of glycemic control and glucose variability (GV); lipid panels; estimated glomerular filtration rate (eGFR); albuminuria; blood cell count; and coagulation. Additionally, serum levels of calponin-1, relaxin, L-citrulline, and matrix metalloproteinase-2 and -3 (MMP-2, -3) were measured by ELISA.

In univariate analysis, older age, male sex, diabetes duration, GV, diabetic retinopathy, chronic kidney disease, coronary artery disease, peripheral artery disease, and MMP-3 were associated with subclinical CA. In addition to these factors, long-term arterial hypertension, high daily insulin doses, eGFR, and L-citrulline were associated with CAS. In multivariate logistic regression, age, male sex, BMI, GV, and eGFR predicted CA independently; male sex, BMI, diabetes duration, eGFR, and L-citrulline were predictors of CAS. These results can be used to develop screening and prevention programs for CA and CAS in T2D subjects.
Spin relaxation was studied in a two-dimensional electron gas confined in a wide GaAs quantum well. Recently, the control of the spin relaxation anisotropy by diffusive motion was first shown in D. Iizasa et al., arXiv:2006.08253 (2020).

Here, we demonstrate electrical control by drift transport in a system with two-subbands occupied. The combined effect of in-plane and gate voltages was investigated using time-resolved Kerr rotation.

The measured relaxation time present strong anisotropy with respect to the transport direction. For an in-plane accelerating electric field along $\left[110\right]$, the lifetime was strongly suppressed irrespective of the applied gate voltage. Remarkably, for transport along $\left[1\bar{1}0\right]$, the data shows spin lifetime that was gate-dependent and longer than in the $\left[110\right]$ direction regardless of the in-plane voltage. In agreement, independent results of anisotropic spin precession frequencies are also presented. Nevertheless, the long spin lifetime, strong anisotropy and drift response seen in the data are beyond the existing models for spin drift and diffusion.

In this paper we propose the algorithm of automated definition of the genre type and semantic characteristics of poetic texts in Russian.

We formulated the approaches to the construction of a joint ("two-dimensional") classifier of genre types and stylistic colouring of poetic texts, based on the definition of interdependence of the type of genre and stylistic colouring of the text. On the basis of these approaches the principles of formation of the training samples for the algorithms for the definition of styles and genre types were analyzed. The computational experiments with a corpus of texts of the Lyceum lyrics of A.S.Pushkin were implemented.

The proposed algorithms can be used for automation of the complex analysis of Russian poetic texts, significantly facilitating the work of the expert in determining their styles and genres by providing appropriate recommendations.
The relationship of the pulsations of flow in the settling chamber with the pulsations of supersonic flow in the test section of the T-325 wind tunnel of ITAM SB RAS was investigated.

The system of three-channel hot-wire measurements in subsonic and supersonic flows was tested.

Experimental data on the correlation between flow pulsations in different sections of wind tunnel and efficiency of turbulence reducing system were obtained.
Functional nutrition is a valuable supplementation to dietary therapy. Functional foods are enriched with biologically active substances. Plant polyphenols attract particular attention due to multiple beneficial properties attributed to their high antioxidant and other biological activities.

We assessed the effect of grape polyphenols on the life span of C57BL/6 mice and on behavioral and neuroinflammatory alterations in a transgenic mouse model of Parkinson disease (PD) with overexpression of the A53T-mutant human α-synuclein. C57BL/6 mice were given a dietary supplement containing grape polyphenol concentrate (GPC—1.5 mL/kg/day) with drinking water from the age of 6–8 weeks for life. Transgenic PD mice received GPC beginning at the age of 10 weeks for four months.

GPC significantly influenced the cumulative proportion of surviving and substantially augmented the average life span in mice. In the transgenic PD model, the grape polyphenol (GP) diet enhanced memory reconsolidation and diminished memory extinction in a passive avoidance test. Behavioral effects of GP treatment were accompanied by a decrease in α-synuclein accumulation in the frontal cortex and a reduction in the expression of neuroinflammatory markers (IBA1 and CD54) in the frontal cortex and hippocampus. Thus, a GP-rich diet is recommended as promising functional nutrition for aging people and patients with neurodegenerative disorders.
We comprehensively review the deceptively simple concept of dipole scattering in order to uncover and resolve all ambiguities and controversies existing in the literature.

First, we consider a point electric dipole in a non-magnetic environment as a singular point in space whose sole ability is to be polarized due to the external electric field. We show that the postulation of the Green's dyadic of the specific form provides the unified description of the contribution of the dipole into the electromagnetic properties of the whole space. This is the most complete, concise, and unambiguous definition of a point dipole and its polarizability. All optical properties, including the fluctuation–dissipation theorem for a fluctuating dipole, are derived from this definition. Second, we obtain the same results for a small homogeneous sphere by taking a small-size limit of the Lorenz–Mie theory. Third, and most interestingly, we generalize this microscopic description to small particles of arbitrary shape. Both bare (static) and dressed (dynamic) polarizabilities are defined as the double integrals of the corresponding dyadic transition operator over the particle's volume.

While many derivations and some results are novel, all of them follow from or are connected with the existing literature, which we review throughout the paper.
Diamond crystallization in melts of europium salts (Eu2(C2O4)3·10H2O, Eu2(CO3)3·3H2O, EuCl3, EuF3, EuF2) at 7.8 GPa and in a temperature range of 1800–2000 °C was studied for the first time. Diamond growth on seed crystals was realized at a temperature of 2000 °C. Spontaneous diamond nucleation at these parameters was observed only in an Eu oxalate melt. The maximum growth rate in the europium oxalate melt was 22.5 μm/h on the {100} faces and 12.5 μm/h on the {111} faces. The diamond formation intensity in the tested systems was found to decrease in the following sequence: Eu2(C2O4)3·10H2O > Eu2(CO3)3·3H2O > EuF3 > EuF2 = EuCl3. Diamond crystallization occurred in the region of stable octahedral growth in melts of Eu3+ salts and in the region of cubo-octahedral growth in an EuF2 melt. The microrelief of faces was characterized by specific features, depending on the system composition and diamond growth rate. In parallel with diamond growth, the formation of metastable graphite in the form of independent crystals and inclusions in diamond was observed. From the spectroscopic characterization, it was found that diamonds synthesized from Eu oxalate contain relatively high concentrations of nitrogen (about 1000−1200 ppm) and show weak PL features due to inclusions of Eu-containing species.
Single tandem repeat (STR) polymorphisms are widely used in linkage and association studies. One of the drawbacks of using these markers is that genetic data coming from different experiments cannot be easily pooled together, because both allele length and binning distance may change. As large studies with multiple series of subjects sequentially included become more and more common, there is an increasing interest in pooling the genetic data obtained in different experiments. Correct reconstruction of allelic correspondences between genotyping experiments is particularly crucial for association‐oriented studies, such as candidate gene studies and genome‐wide association studies in isolated populations.

Here, we suggest a maximum‐likelihood framework to find the best correspondence between alleles typed in different genotyping experiments. We also address the issue of goodness‐of‐fit and robustness. We perform a study simulating results obtained in a genome scan using 787 STR markers.

The simulations show that the suggested method yields good results with respect to the error rate, even if the sizes of the samples to be pooled are as low as 10 subjects (3% errors), though only 9% of alleles pass our tests. As sample sizes increase to 250 subjects the proportion of alleles pooled reaches 96% with an error rate of <0.1%.
The evaluation of the indicators according to the criterion of social justice is carried out using two groups of methods: firstly, statistical, primarily the Gini coefficients (which are based on the households’ incomes in regions or country as a whole), and secondly, methods for constructing isoelastic social welfare functions at the national and regional or zonal levels, which are based on the households’ utility functions and include the inequality rejection coefficient.

The article proposes a methodological approach for assessing the territorial inequality based on an agent-oriented spatial model. The main decisions are made in the model at the microeconomic level by households and enterprises with spatial coordinates. Then they are aggregated to the level of regions, industries and the economy as a whole. The model simulates the development of the government social policy, which is carried out by changing taxes and transfers and taking into account the degree of territorial inequality. Model calculations consider pensions and five types of monetary transfers in a fixed structure: unemployment benefits, child benefits, poverty benefits, social aid and basic income benefits.

In a series of experiments, the effect on territorial inequality of changes in the total value of social transfers (with their fixed structure) and tax rates in accordance with the proportionality coefficients was assessed. It is used as a toolkit for changing the system of taxes and transfers and for supporting social policy to reduce spatial inequalities in Russia.
The influence of microwave radiation (1.2-140 GHz) on resistance of high-mobility two-dimensional electron gas in GaAs quantum wells is studied. Two series of microwave-induced magnetoresistance oscillations periodic in 1/B were observed under microwave radiation. The periods of oscillations are determined by the microwave frequency and power, correspondingly. The experimental data is qualitatively explained by photon-assisted transport and Zener tunneling between Landau orbits.
This is the first observation of the decay η_c → η' K⁺ K⁻ and we measure the branching fraction Γ(η_c → η' K⁺ K⁻)/(Γ(η_c → η' π⁺ π⁻)=0.644±0.039_stat±0.032_sys. Significant interference is observed between γγ → η_c → η π⁺ π⁻ and the non-resonant two-photon process γγ → η π⁺ π⁻.

We study the processes γγ → η_c → η' K⁺ K⁻, η' π⁺ π⁻, and η π⁺ π⁻ using a data sample of 519 fb⁻¹ recorded with the BaBar detector operating at the SLAC PEP-II asymmetric-energy e⁺e⁻ collider at center-of-mass energies at and near the Υ(nS) (n = 2,3,4) resonances. A Dalitz plot analysis is performed of η_c decays to η' K⁺ K⁻, η' π⁺ π⁻, and η π⁺ π⁻. Combined with our previous analysis of η_c → K K̅ π, we measure the K*₀(1430) parameters and the ratio between its η' K and π K couplings.

The decay η_c → η' π⁺ π⁻ is dominated by the f₀(2100) resonance, also observed in J/ψ radiative decays. A new a₀(1700) → η π resonance is observed in the η_c → η π⁺ π⁻ channel. We also compare η_c decays to η and η' final states in association with scalar mesons as they relate to the identification of the scalar glueball.
Community-acquired pneumonia is one of the most common infectious diseases and remains one of the leading causes of death in this group of diseases. Studies of community-acquired pneumonia are extremely relevant for modern clinical practice. One of the important role in the pathogenesis of bacterial, viral, fungal invasion in the system of a human lung system belongs to the pulmonary surfactant, in particular, its proteins SP-A and SP-D. This article reviews the well-known mechanisms of important biological properties of immunomodulatory activity of the proteins SP-A and SP-D in response to microbial infection in the lungs. The mechanisms of participation of surfactant proteins SP-A and SP-D in the cascade of reactions that lead to severe life-threatening complications in community-acquired pneumonia are considered. The use of serum levels of surfactant proteins SP-A and SP-D can help finding new diagnostic and prognostic approaches in patients with community-acquired pneumonia.
. The model of the observed object plays the key role in the task of object tracking. Models as a set of image parts, in particular, keypoints, is more resistant to the changes in shape, texture, angle of view, because local changes apply only to specific parts of the object. On the other hand, any model requires updating as the appearance of the object changes with respect to the camera. In this paper, we propose a dynamic (time-varying) model, based on a set of keypoints. To update the data this model uses the algorithm of rating keypoints and the decision rule, based on a Function of Rival Similarity (FRiS). As a result, at the test set of image sequences the improvement was achieved on average by 9.3% compared to the original algorithm. On some sequences, the improvement was 16% compared to the original algorithm.
The present paper discusses methodological approaches to the creation of nomenclatural standards and genetic passports for Russian cultivars, currently being developed at the N.I. Vavilov Institute of Plant Genetic Resources (VIR) in collaboration with different breeding research centers.

Plant material of potato cultivars bred in the Siberian Research Institute of Plant Cultivation and Breeding was collected by the cultivar creator A.D. Safonova in the experimental field of this institute and transferred to the VIR herbarium for preparation of their nomenclatural standards. Plant shoots and tubers of potato cultivars bred in other Siberian research centers in collaboration with the A.G. Lorkh All-Russian Research Institute of Potato Farming (VNIIKH) was collected by the representative of this institute in the experimental field of VNIIKH. Nomenclatural standards were prepared according to the ‘International Code of Nomenclature for Cultivated Plants’. DNA samples isolated from nomenclatural standards were used for preparation of genetic passports of these 11 cultivars. A similar set of DNA markers was used for genotyping cultivar accessions from the in vitro and field collections of various institutes as well as cultivar specimens from eco-geographical tests performed within the framework of the Comprehensive Research Plan of the subprogram “Development of potato breeding and seed production in the Russian Federation”.

As a result of joint research, nomenclatural standards were accomplished for 11 cultivars, namely ‘Аntonina’, ‘Zlatka’, ‘Lina’, ‘Lûbava’, ‘Nakra’, ‘Pamâti Rogačeva’, ‘Sarovskij’, ‘Safo’, ‘Solnečnyj’, ‘Tuleevskij’, ‘Ûna’ bred in five different Siberian breeding institutes including cultivars developed in collaboration with VNIIKH. These genetic passports include information of the polymorphism of eight chromosome-specific microsatellites, data on the markers of 11 R-genes conferring resistance to various harmful organisms, as well as the information about cytoplasm types. Voucher specimens of additional three Siberian cultivars ‘Kemerovčanin’, ‘Kuznečanka’, ‘Tanaj’ and five Ural cultivars ‘Аlâska’, ‘Bravo’, ‘Irbitskij’, ‘Lûks’, ‘Terra’ from the Ural Research Institute for Agriculture were also registered in the VIR herbarium collection. For these eight cultivars, the genetic passports were not issued, but the results of SSR genotyping and molecular screening of voucher specimens performed with the same set of the DNA markers are presented in this report. The comparison of cultivar genetic passport data with genotyping results of specimens having the same name, but obtained from different sources made it possible to verify this plant material.
In the last decade, preoperative modelling of the treatment of cerebral aneurysms is being actively developed. Fluid-structure interaction problem is a key point of a such modelling. Hence arises the question about the reasonable choice of the model of the vessel and aneurysm wall material to build the adequate model from the physical point of view. This study covers experimental investigation of 8 tissue samples of cerebral aneurysms and 1 tissue sample of a healthy cerebral artery. Results on statistical significance in ultimate stress for the classification of 2 cohorts of aneurysms: ruptured and unruptured described earlier in the literature were confirmed (p ≤ 0.01). We used the four most common models of hyperelastic material: Yeoh, Neo-Hookean and Mooney-Rivlin (3 and 5 parameter) models to describe the experimental data. In this study for the first time, we obtained a classification of hyperelastic models of cerebral aneurysm tissue, which allows to choose the most appropriate model for the simulation problems requirements depending on the physical interpretation of the considered problem: aneurysm status and range of deformation.
Cold atmospheric plasma (CAP) jet generated by the plasma source at 2-6 kV ac voltages with frequencies of 10-50 kHz demonstrate the different modes of operation. Depending on the voltage frequency and amplitude, some streamers in the plasma jet are short and decay before they approach the treated surface. In this case, the effect on the viability of cancer cells when exposed to CAP jet strongly depends on the mode of operation of the discharge or, in other words, on how many times the streamers hit the bio-target during the treatment. The effect on different modes on cancer cells A549 viability is reported.
Structural homology modeling supported by bioinformatics analysis plays a key role in uncovering new molecular interactions within gene regulatory networks. Here, we have applied this powerful approach to analyze the molecular interactions orchestrating death receptor signaling networks. In particular, we focused on the molecular mechanisms of CD95-mediated NF-κB activation and the role of c-FLIP/NEMO interaction in the induction of this pathway.To this end, we have created the homology model of the c-FLIP/NEMO complex using the reported structure of the v-FLIP/NEMO complex, and rationally designed peptides targeting this complex. The designed peptides were based on the NEMO structure. Strikingly, the experimental in vitro validation demonstrated that the best inhibitory effects on CD95-mediated NF-κB activation are exhibited by the NEMO-derived peptides with the substitution D242Y of NEMO. Furthermore, we have assumed that the c-FLIP/NEMO complex is recruited to the DED filaments formed upon CD95 activation and validated this assumption in silico. Further insight into the function of c-FLIP/NEMO complex was provided by the analysis of evolutionary conservation of interacting regions which demonstrated that this interaction is common in distinct mammalian species.Taken together, using a combination of bioinformatics and experimental approaches we obtained new insights into CD95-mediated NF-κB activation, providing manifold possibilities for targeting the death receptor network.
The article is devoted to a number of solutions for organizing work with memory in educational languages and programming systems aimed at teaching the preparation of multi-threaded programs over shared memory. The consideration was carried out within the framework of the SYNCHRO programming language for educational purposes, which made it possible to analyze variants of such solutions without the limitations typical for traditional manufacturing tools and devices of standard programming systems. The article gives a clear formulation of an abstract machine and a diagram of a command system that allows you to define the behavior of a program as a distributed system from a number of threads interacting in terms of access to the values of variables located in shared memory. The de-vice of shared memory and mechanisms of access to it by individual processes, which are a sequence of command execution, some of which are requests to shared memory, are described. The focus is on the convenience of debugging small programs used to introduce concurrency problems in the learning process, where the pace of learners’ under-standing of the problems is more important than achieving program efficiency and performance. The solution to this problem is useful when studying programming methods, as well as studying the history of programming languages, comparing programming paradigms, the potential of the schemes and models used, assessing the level of novelty of the programming languages being created, creating a technique for measuring different characteristics of programs on models and choosing criteria for the practicality of the created programs. When choosing a system of commands for an abstract machine, the principles of functional programming were taken into account as a popular paradigm at the stage of preparing prototypes and models of multi-threaded programs. From these principles, the conclusion is drawn of the consequences that allow you to successfully select elementary instructions that support working with memory in the style of data immutability and their transactional processing. For educational tasks in programming, the ability to ensure the correctness and completeness of solutions is more important than the efficiency and productivity of the received programs. This is the path to building reliable and secure software.
The first historical part is devoted to the works done half a century ago with an emphasize to those performed in Russia (or more precisely, in the Soviet Union). Then the recent data on the cosmic microwave background raditation is discussed and the impact of these data on the neutrino mass and the number of neutrino species is considered. The latter is compared with the results obtained from the big bang nucleosynthesis.

Next, a short description and history of the cosmological inflation is presented. The basics of the standard cosmological model and the problems of dark matter and dark energy are considered at the end of the fist section entitled 'Progress'.

In the next short section, 'Problems', one can find a list of the unsolved cosmological and astrophysical problems, which is by no means fully comprehensive. The last supershort section contains a few words about the perspectives of future development.
