We propose a method for scientific terms extraction from the texts in Russian based on weakly supervised learning. This approach doesn't require a large amount of hand-labeled data.

To implement this method we collected a list of terms in a semi-automatic way and then annotated texts of scientific articles with these terms. These texts we used to train a model. Then we used predictions of this model on another part of the text collection to extend the train set. The second model was trained on both text collections: annotated with a dictionary and by a second model.

Obtained results showed that giving additional data, annotated even in an automatic way, improves the quality of scientific terms extraction.

This article discusses the main facts about one of the leaders of the nomadic Ewenkis of Transbaikalia  Gantimur, who in 1666/67 left Qing empire and got through the process of naturalization in Russia. The author criticizes the narrative that is widespread in the state and local historical works and genealogical writings. According to it, Gantimur belonged to the Manchu ruling elite and allegedly participated in 1655 in the attack on the Russian Komarsky ostrog (fortress), located on the right bank of the Amur.

Based on the analysis of a broad range of archival and published sources (petitions of Gantimur and his descendants, reports of Russian explorers and administrators, diplomatic documents drawn up during the Russian-Manchu negotiations) and historical research, it is shown, how this narrative appeared and became prevalent.

The author proves that this historical myth does not correspond to real facts and was fabricated by the grandchildren of Gantimur in order to improve their status in the Russian social hierarchy and increase wealth. This article concludes by arguing that Gantimur was not part of the Manchu elite and did not take part in the Manchu campaigns on the Amur river.
We report the first observation of the doubly Cabibbo-suppressed decay D_{s};{+}-->K;{+}K;{+}pi;{-} using 605 fb;{-1} of data collected with the Belle detector at the KEKB asymmetric-energy e;{+}e;{-} collider. The branching ratio with respect to its Cabibbo-favored counterpart B(D_{s};{+}-->K;{+}K;{+}pi;{-})/B(D_{s};{+}-->K;{+}K;{-}pi;{+}) is (0.229+/-0.028+/-0.012)%, where the first uncertainty is statistical and the second is systematic. We also report a significantly improved measurement of the doubly Cabibbo-suppressed decay D;{+}-->K;{+}pi;{+}pi;{-}, with a branching ratio B(D;{+}-->K;{+}pi;{+}pi;{-})/B(D;{+}-->K;{-}pi;{+}pi;{+})=(0.569+/-0.018+/-0.014)%.
We propose the study of the inclusive hadroproduction of a heavy-flavored jet in association with a light jet, as a probe channel of strong interactions at high energies. We build up a hybrid factorization that encodes genuine high-energy effects, provided by a partial next-to-leading BFKL resummation, inside the standard collinear structure of the cross section. We present a detailed analysis of different distributions, shaped on kinematic ranges typical of experimental analyses at the Large Hadron Collider, and differential in rapidity, azimuthal angle and transverse momentum. The fair stability that these distributions exhibit under higher-order corrections motivates our interest toward future studies. Here, the hybrid factorization could help to deepen our understanding of heavy-flavor physics in wider kinematic ranges, like the ones accessible at the Electron-Ion Collider.
Validation of the previously proposed implicit criterion of fracture propagation was carried out. The implicit criterion at each step of the propagation considers the rock stress state both before and after the propagation.

It is based on the assumption that the fracture tends to propagate in the direction where II and III modes of stress intensity factor (SIF) are zero. Since in most cases both conditions cannot be satisfied simultaneously, the values of the SIF modes II and III are combined in one function and are integrated along the whole front. A few possible propagation directions are considered at each step of the propagation and the one is chosen to provide the minimum of the integral.

The criterion parameters was chosen using the comparison with experiment results and semi analytical formulas obtained from three point bend test with twisted fracture.

At the heart of the code – the new original low-dissipation numerical method based on a combination of operator splitting approach and piecewise-parabolic method on the local stencil. The chemodynamics of the hydrogen while the turbulent formation of molecular clouds is modeled.
The study reveals the place and role of humanism in the philosophy of K. Marx and J.-P. Sartre.

The existential aspects of their teachings that allow one to consider these philosophers as equal are analyzed. A comparison of humanistic motifs in Marx and Sartre's works has been made.

The conclusion is drawn that their description of the 'world of alienation' is the same. However, they consider the pre-existing and post-existing reality differently, which is due to different positions on the relationship between essence and existence.

The relaxational kinetics of the photoemission from the Cs/GaAs and GaAs(Cs,O) surfaces at elevated temperatures is studied.

It was found that heating to moderate temperatures of about 150°C leads to substantial changes in the amplitude and shape of the Cs coverage dependences of the photoemission current, along with the changes of its relaxational kinetics after the cesium deposition. After the oxygen exposure on the GaAs(Cs,O) surface, a photoemission relaxational increase is observed due to changes in the affinity.

The temperature dependences of the amplitude and decay time of the relaxational kinetics on the Cs/GaAs and GaAs(Cs,O) surfaces were obtained.
We study an initial boundary value problem for a system of quasilinear equations which are effectively used for finding by the stabilization method numerical stationary solutions of the hydrodynamical model of charge transport in the silicon MESFET (metal semiconductor field effect transistor). This initial boundary value problem has the following peculiarities: the PDE system is not a Cauchy-Kovalevskaya-type system; the boundary is a nonsmooth curve and has angular points; nonlinearity of the problem is mainly connected with squares of gradients of the unknown functions.

By using a special representation for the solution of a model problem we reduce the original problem to a system of integro-differential equations.

This allows one to prove the local-in-time existence and uniqueness of a weakened solution. Using a constructed energy integral and the Schauder fixed-point theorem, we prove the global-in-time solvability of the initial boundary value problem and justify the stabilization method under additional assumptions on the problemâs data.
We report one-step fast synthesis and consolidation of iron aluminide FeAl of high open porosity by pressureless reactive Spark Plasma Sintering (SPS). The starting material of the Fe-40at.%Al composition was a mixture of an iron powder with an average particle diameter of 4 μm and an aluminum powder with an average particle diameter of 6 μm. The rationale behind the choice of the SPS as a processing technique and fine and comparable sizes of the two reactants for the synthesis of high-open porosity FeAl was realization of fast full chemical conversion of Fe and Al into single-phase FeAl reducing the time available for the compact shrinkage. According to the XRD phase analysis, single-phase FeAl compacts formed after SPS at 800 and 900°C. These compacts had open porosities of 41 and 46%, respectively. The transverse rupture strength of the compacts sintered at 700-900°C was found to change little with the sintering temperature in the selected range.
The dependence of wakefield amplitude and phase on beam and plasma parameters is studied in the parameter area of interest for self-modulating proton beam-driven plasma wakefield acceleration.

The wakefield phase is shown to be extremely sensitive to small variations of the plasma density, while sensitivity to small variations of other parameters is reasonably low.

The study of large parameter variations clarifies the effects that limit the achievable accelerating field in different parts of the parameter space: nonlinear elongation of the wakefield period, insufficient charge of the drive beam, emittance-driven beam divergence, and motion of plasma ions.
Modern high-power lasers exhibit a rich diversity of nonlinear dynamics, often featuring nontrivial co-existence of linear dispersive waves and coherent structures. While the classical Fourier method adequately describes extended dispersive waves, the analysis of time-localised and/or non-stationary signals call for more nuanced approaches. Yet, mathematical methods that can be used for simultaneous characterisation of localized and extended fields are not yet well developed.

Here, we demonstrate how the Nonlinear Fourier transform (NFT) based on the Zakharov-Shabat spectral problem can be applied as a signal processing tool for representation and analysis of coherent structures embedded into dispersive radiation. We use full-field, real-time experimental measurements of mode-locked pulses to compute the nonlinear pulse spectra. For the classification of lasing regimes, we present the concept of eigenvalue probability distributions.

We present two field normalisation approaches, and show the NFT can yield an effective model of the laser radiation under appropriate signal normalisation conditions.
Raman scattering spectra were obtained at 25-320 K for bilayers prepared from saturated 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) and mono-unsaturated 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) phospholipids, with and without cholesterol. Raman intensities were measured at modes sensitive to lipid inter-chain interactions and/or intra-chain torsional motion (asymmetric CH2 stretching at 2880 cm(-1)) and to the conformational state of lipids (C-C stretching at 1130 cm(-1)). These intensities decreased with temperature, which could be ascribed to increased lipid flexibility. For cholesterol-free and cholesterol-containing DPPC bilayers, the decrease of Raman intensities observed above ∼200 K could be related to the phenomenon of dynamical transition known for biological systems near these temperatures. For a cholesterol-free POPC bilayer, the decrease of intensity for the asymmetric CH2 stretching mode started at a lower temperature, above 100 K, while the addition of cholesterol shifted this starting temperature to a more normal ∼200 K value. The low-temperature lipid flexibility in the case of POPC was related to the abundance of free-volume holes, which disappeared in presence of cholesterol. Near gel-fluid phase transitions, Raman intensities for cholesterol-free bilayers dropped sharply, while for cholesterol-containing bilayers, they changed smoothly.
Background: Dendritic cells (DCs) are known to contribute to the pathogenesis of different autoimmune diseases. It is clear nowadays the role of DCs in rheumatoid arthritis (RA) but not well investigated in Axial spondylitis (AxSpA). DCs are a heterogeneous population and can be divided into groups: myeloid (mDCs) and plasmacytoid (pDCs). DCs can induce both immune response and tolerance.

Methods: The study include sixty five patients with early forms of diseases including 55 patients with RA and 10 patients with AxSpA. Diagnosis RA was established according ACR/EULAR criteria (2010). Diagnosis AxSpA was established according ASAS criteria. All patients received conventional synthetic DMARDs. Thirty patients with osteoarthritis (OA) used as a control group. Analysis of the content of the B-lymphocytes, myeloid and plasmacytoid DCs was carried out by flow cytometry. B-lymphocytes, subtypes of peripheral blood DCs were characterized by the following phenotypes: myeloid DCs (CD3-CD14-CD19-HLA-DR + CD11c + CD123-), plasmacytoid DCs (CD3-CD14-CD19-HLA-DR + CD11c-CD123 +), B-lymphocytes (CD19 +). Analyses were performed before treatment and after 3 and 6 months.

Conclusion: The data obtained indicate that early form of rheumatic diseases namely rheumatoid arthritis and axial spondylitis have the common features such as the dominance of mDCs and their decreasing in reduction of activity of disease.
The authors continue to use hardware acceleration to calculate tsunami wave propagation in a few seconds at modern PC. The FPGA-based Calculator, for regular grid has been proposed and numerically tested earlier.

The goal of this work is to develop original implementation the FPGA-based algorithm for nested-grids computations of tsunami wave propagation. Use of the nested grid approach makes it possible to calculate wave propagation almost until the shore line. Numerical tests are based on the real digital bathymetry at southern part of Japan. Mesh step variation of the gird is from 180 m to just 7 m. Realistic shape of the initial sea surface displacement at tsunami source was used.

The detailed distribution of wave height maxima around and inside the Onahama port have been issued as a result of tsunami generated by a model source located along the Japan deep-water trench. The superfast FPGA calculator provides an opportunity to obtain the calculated wave parameters inside ports and harbours even before arrival of tsunami wave.
Many xenobiotics in the human environment, such as benzo[a]pyrene (B(a)P) and dichlorodiphenyltrichloroethane (DDT), may act as non-genotoxic carcinogens through epigenetic mechanisms, including changes in microRNA expression profile. In part, such disorders can be mediated by the activation of nuclear receptors, resulting in the activation of protein coding gene expression and microRNAs involved in malignant transformation of cells. Therefore, the aim of this study was to investigate the chain of events “xenobiotic administration – receptor activation – up-regulating microRNA expression – down-regulation target genes expression” as one of the key factors in the chemically-induced carcinogenesis. Using in silico methods, an analysis of the rat genome was carried out to find microRNAs putatively regulated by AhR (aryl hydrocarbon receptor) and CAR (constitutive androstane receptor), activated by BP and DDT, respectively. In particular, miR-3577 and -193b were selected as potentially regulated CAR, miR-207 was selected as a candidate for miR under AhR regulation. The results of the study showed that the treatment of female rats with DDT and B(a)P caused a tissue-specific changes in the expression of microRNAs and host genes in both acute and chronic administration of xenobiotics. To confirm the effects of xenobiotics on the microRNA expression, we also estimated the mRNA level of PTPN6, EIF3F, Cbx7, and Dicer1 genes potentially targeting miR-193b, -207, and -3577. The study has shown a high correlation between the expression of target genes and microRNAs; however these changes depended on the tissue types, the dose and time after xenobiotic treatment.
This article suggests ways to quickly assess the state of labor protection and ecology by calculating a number of indicators of industrial risk based on the information available in the modules for assessing labor protection by indicators of industrial risk. The efficiency of using the software proposed by the authors for the occupational health and safety management system based on a specific task from the modules "Personnel", "Events", "Equipment" and "Ecology", consisting of four main modules, is proved. In addition, this paper compares the matrix methods of risk assessment in the coordinate system "probability of an event or consequences of an event" of prevention and assessment of occupational risks for employees used in domestic and foreign practice in the occupational safety management system.Work on identifying harmful factors of accidents during the extraction, use and transportation of raw materials at industrial enterprises and assessing compliance with the requirements of the standards of the Republic of Kazakhstan should be carried out continuously. The main goal of the labor protection service is to create safe working conditions for employees at industrial enterprises, as well as to prevent occupational diseases of employees. In this regard, a system of accounting, analysis and assessment of the state of labor protection, as well as labor safety management, should work.
The sublethal effects of high predation risk on both prey behavior and physiology may have long-term consequences for prey population dynamics. Snowshoe hares exhibit 10-yr population cycles; during declines, virtually every hare that dies is killed by a predator.

We assessed the physiological responsiveness of the stress axis and of energy mobilization by subjecting hares during the population decline and low to a hormonal-challenge protocol. We monitored the population demography through live-trapping and assessed reproduction through a maternal-cage technique.

During the 1990s' decline in the Yukon, Canada, hares were chronically stressed—as indicated by higher levels of free cortisol, reduced maximum corticosteroid-binding capacity, reduced testosterone response, reduced index of body condition, reduced leucocyte counts, increased overwinter body-mass loss, and increased glucose mobilization, relative to hares during the population low. This evidence is consistent with the explanation that predation risk, not high hare density or poor nutritional condition, accounted for the chronic stress and for the marked deterioration of reproduction during the decline. Reproduction and indices of stress physiology did not improve until predation risk declined. These findings may also account for the lag in recovery of hare reproduction after predator densities have declined and thus may implicate the long-term consequences of predation risk on prey populations beyond the immediate effects of predators on prey behavior and physiology.
Interest in the research of compressibility of such mixtures is associated with the possibility of creating materials with the necessary properties, and with the properties of the materials themselves.

The results of numerical experiments on modeling shock-wave loading of metal composites – elkonites, which are sintered refractory materials (W, WC or Mo) impregnated with fusible metal (Ag or Cu) using thermodynamically equilibrium model TEC (thermodynamic equilibrium components) are presented. The modelling of materials with such components is carried out to develop the promising direction of obtaining materials with specified properties.

The good agreement of the model calculations with the data of different authors, which are determined on the basis of experiment, is obtained.

Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
Chimeric antigen receptors (CARs) are recombinant protein molecules that redirect cytotoxic lymphocytes toward malignant and other target cells. The high feasibility of manufacturing CAR-modified lymphocytes for the therapy of cancer has spurred the development and optimization of new CAR T cells directed against a broad range of target antigens. In this review, we describe the main structural and functional elements constituting a CAR, discuss the roles of these elements in modulating the anti-tumor activity of CAR T cells, and highlight alternative approaches to CAR engineering.
Human 8-oxoguanine-DNA glycosylase (OGG1) efficiently removes mutagenic 8-oxo-7,8-dihydroguanine (8-oxoGua) and 2,6-diamino-4-hydroxy-5-formamidopyrimidine when paired with cytosine in oxidatively damaged DNA. Excision of 8-oxoGua mispaired with adenine may lead to G-->T transversions. Post-translational modifications such as phosphorylation could affect the cellular distribution and enzymatic activity of OGG1. Mutations and polymorphisms of OGG1 may affect the enzymatic activity and have been associated with increased risk of several cancers.

In this study, we used double-stranded oligodeoxynucleotides containing 8-oxoGua:Cyt or 8-oxoGua:Ade pairs, as well as gamma-irradiated calf thymus DNA, to investigate the kinetics and substrate specificity of several known OGG1 polymorphic variants and phosphomimetic Ser-->Glu mutants.

Among the polymorphic variants, A288V and S326C displayed opposite-base specificity similar to that of wild-type OGG1, whereas OGG1-D322N was 2.3-fold more specific for the correct opposite base than the wild-type enzyme. All phosphomimetic mutants displayed approximately 1.5-3-fold lower ability to remove 8-oxoGua in both assays, whereas the substrate specificity of the phosphomimetic mutants was similar to that of the wild-type enzyme. OGG1-S326C efficiently excised 8-oxoGua from oligodeoxynucleotides and 2,6-diamino-4-hydroxy-5-formamidopyrimidine from gamma-irradiated DNA, but excised 8-oxoG rather inefficiently from gamma-irradiated DNA. Otherwise, kcat values for 8-oxoGua excision obtained from both types of experiments were similar for all OGG1 variants studied. It is known that the human AP endonuclease APEX1 can stimulate OGG1 activity by increasing its turnover rate. However, when wild-type OGG1 was replaced by one of the phosphomimetic mutants, very little stimulation of 8-oxoGua removal was observed in the presence of APEX1.
The purpose of this paper is to develop further the main concepts of Phenomena Dynamic Logic (P-DL) and Cognitive Dynamic Logic (C-DL), presented in the previous paper. The specific character of these logics is in matching vagueness or fuzziness of similarity measures to the uncertainty of models.

These logics are based on the following fundamental notions: generality relation, uncertainty relation, simplicity relation, similarity maximization problem with empirical content and enhancement (learning) operator. We develop these notions in terms of logic and probability and developed a Probabilistic Dynamic Logic of Phenomena and Cognition (P-DL-PC) that relates to the scope of probabilistic models of brain.

In our research the effectiveness of suggested formalization is demonstrated by approximation of the expert model of breast cancer diagnostic decisions. The P-DL-PC logic was previously successfully applied to solving many practical tasks and also for modelling of some cognitive processes.
Development of collective intelligence and consciousness starts playing key evolutionary role given spread of social networks and massive Internet communications. Paper considers cognitive model and architecture capable to capture cognitive phenomena in social environments, which could be used for modeling of collective cognition as well as developing practical applications for individual interaction with collective intelligence. The model is evaluated by means of qualitative and quantitative experiments.
