The article presents a regression analysis of banking determinants and their impact on the capital structure of banks for the period 2011–2019 on an extensive statistical base of the countries of India, Russia, China, the USA and banks in the Eurozone. The study proceeds and is based on the empirical results of the analysis of the structure of bank capital, carried out for individual countries up to the specified period. These results turned out to be quite contradictory regarding the significance of different determinants of the structure of bank capital. Understanding the influence of the determinants on the stability of the banking system, the article attempts to explain the differences for the period 2011–2019, when the countries' banking systems adopted the Basel 3 capital adequacy requirements. It is shown that 1) the capital structure of banks is influenced not only by banking determinants, but also by development conditions, regulatory institutions, the state of the economy, which is evidence of the need to analyze the problems of forming the capital structure of banks by countries, types of banks, etc.; 2) banking determinants between 2011 and 2019 explain the variation in bank capital structure to a significant extent and regulatory action is relevant for all countries. From the point of view of the peculiarities of the formation of the structure of bank capital and the role of the regulator in this case, directions of modification of relevant theories of capital structure are proposed.
Activated carbons were prepared from rice husk carbonized in the fluidized catalysts bed reactor.

Using the different activating agents, samples with BET surface area in the range from 540 to 3060 m2/g were achieved. Using sodium or potassium carbonates results in the BET surface area up to 1400 m2/g. Hydroxides of sodium or potassium yield the samples with the higher BET surface area (up to 3060 m2/g). Textural peculiarities of the carbons were studied by the adsorption of nitrogen at 77 K and of carbon dioxide at 273 K. As active materials for supercapacitors, the porous carbon samples were examined by cyclic voltammetry and chronopotentiometry in galvanostatic mode in 1 M H2SO4 as the electrolyte using home-made three-electrode electrochemical glass cell.

Gravimetric capacitance of the carbons is linearly proportional to the BET surface area and reaches 230 and 196 F/g at discharge current density of 0.2 and 1 A/g, respectively, for the samples with the highest surface area.
Two new triterpenoid saponins 1 and 2 were isolated from the methanol extract of the roots of Acanthophyllum gypsophiloides Regel. These saponins have quillaic acid or gypsogenin moieties as an aglycon, and both bear similar sets of two oligosaccharide chains, which are 3-O-linked to the triterpenoid part trisaccharide α-L-Arap-(1→3)-[α-D-Galp-(1→2)]-β-D-GlcpA and pentasaccharide β-D-Xylp-(1→3)-β-D-Xylp-(1→3)-α-L-Rhap-(1→2)-[β-D-Quip-(1→4)]-β-D-Fucp connected through an ester linkage to C-28. The structures of the obtained saponins were elucidated by a combination of mass spectrometry and 2D NMR spectroscopy. A study of acute toxicity, hemolytic, anti-inflammatory, immunoadjuvant and antifungal activity was carried out. Both saponins 1 and 2 were shown to exhibit immunoadjuvant properties within the vaccine composition with keyhole limpet hemocyanin-based immunogen. The availability of saponins 1 and 2 as individual pure compounds from the extract of the roots of A. gypsophiloides makes it a prospective source of immunoactive agents.
The theory of magnetoresistance of the edge state of a two-dimensional topological insulator is developed. The magnetic field violates the time-reversal invariance. Magnetoresistance arises due to the energy gap opened by a magnetic field parallel to the sample surface. The combined action of impurities and the magnetic field causes backscattering of edge electrons. Although impurities are necessary for scattering, sufficiently strong interaction with impurities leads to the suppression of backscattering.
We describe generalized running key ciphers and apply them for analysis of two Shannon's methods. In particular, we suggest some estimation of the cipher equivocation and the probability of correct deciphering without key.
Unlike all other regularization schemes in N=2 supersymmetric quantum field theory

We formulate the higher covariant derivative regularization for N=2 supersymmetric gauge theories in N=2 harmonic superspace. This regularization is constructed by adding the N=2 supersymmetric higher derivative term to the classical action and inserting the N=2 supersymmetric Pauli--Villars determinants into the generating functional for removing one-loop divergencies. Together with N=2 supersymmetric background field method this regularization allows to calculate quantum corrections without breaking the manifest gauge symmetry and N=2 supersymmetry.

Thus, we justify the assumption about existence of a regularization preserving N=2 supersymmetry, which is a key element of the N=2 non-renormalization theorem. As a result, we give the prove of the N=2 non-renormalization theorem which does not require any additional assumptions.
The paper explores the potential of using a Virtual Learning Environment in teaching English to Master students at a Russian university. On the base of an e-Learning platform a kind of private website has been created with an online English course for Master students "English for Chemists and Biologists". The course is described in some detail. The Learning Management System supplied by Moodle, an e-Learning platform, is presented. The materials and tools provided by the Moodle system are considered.

The outcomes are discussed of a mixture of a traditional and online English course used to teach the university students. The author endeavours to determine whether the infusion of technology positively influences the acquisition of the English language by the Russian university students.

The author claims that the pedagogical approach which involves both the technology-enhanced teaching and the face-to-face teaching is the approach which is characteristic of the 21st century teaching practice. This promising pedagogical approach helps to improve and innovate language learning in the classroom and outside the classroom.
We report here the characterization of an alternative splice variant of prointerleukin-1α (proIL-1α), constitutively expressed by the normal adult rat testis. In addition to the classical 32K proIL-1α (32proIL-1α) messenger RNA, the testis produced a shorter variant encoding a putative protein of 24K (24proIL-1α). In situ hybridization demonstrated constitutive expression of the splice transcript in the seminiferous tubules. This alternative complementary DNA lacked the fifth exon, harboring the calpain cleavage site essential for generation of mature 17K IL-1α. This was verified by calpain treatment, producing the expected cleavage products of recombinant 32proIL-1α, but not of 24proIL-1α. Similarly, expression in COS-7 cells demonstrated processing of 32proIL-1α to the mature 17K form and secretion, whereas 24proIL-1α remained unprocessed. Both 32proIL-1α and 24proIL-1α showed a dose-dependent stimulatory effect in a thymocyte proliferation assay, although at lower potency than mature 17K IL-1α. In contrast, when tested on hCG-stimulated Leydig cells in vitro, a dose-dependent inhibition of testosterone production was obtained with mature 17K IL-1α and at a lower potency with 32proIL-1α, whereas 24proIL-1α was inactive. In conclusion, the three IL-1 bioactive proteins described here contribute to IL-1 protein heterogeneity and may serve as constitutive paracrine mediators in the testis.
The development of cell models of human diseases based on induced pluripotent stem cells (iPSCs) and a cell therapy approach based on differentiated iPSC derivatives has provided a powerful stimulus in modern biomedical research development. Moreover, it led to the creation of personalized regenerative medicine. Due to this, in the last decade, the pathological mechanisms of many monogenic diseases at the cell level have been revealed, and clinical trials of various cell products derived from iPSCs have begun. However, it is necessary to reach a qualitatively new level of research with cell models of diseases based on iPSCs for more efficient searching and testing of drugs. Biosensor technology has a great application prospect together with iPSCs. Biosensors enable researchers to monitor ions, molecules, enzyme activities, and channel conformation in live cells and use them in live imaging and drug screening. These probes facilitate the measurement of steady-state concentrations or activity levels and the observation and quantification of in vivo flux and kinetics. Real-time monitoring of drug action in a specific cellular compartment, organ, or tissue type; the ability to screen at the single-cell resolution; and the elimination of the false-positive results caused by low drug bioavailability that is not detected by in vitro testing methods are a few of the benefits of using biosensors in drug screening. Here, we discuss the possibilities of using biosensor technology in combination with cell models based on human iPSCs and gene editing systems. Furthermore, we focus on the current achievements and problems of using these methods.
We search for the decay B0s→γγ and measure the branching fraction for B0s→ϕγ using 121.4 fb−1 of data collected at the Υ(5S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. The B0s→ϕγ branching fraction is measured to be (3.6±0.5(stat)±0.3(syst)±0.6(fs))×10−5, where fs is the fraction of B(*)s¯B(*)s in b¯b events. Our result is in good agreement with the theoretical predictions as well as with a recent measurement from LHCb. We observe no statistically significant signal for the decay B0s→γγ and set a 90% confidence-level upper limit on its branching fraction at 3.1×10−6. This constitutes a significant improvement over the previous result.Received 1 December 2014DOI:https://doi.org/10.1103/PhysRevD.91.011101© 2015 American Physical Society
In the paper established clear formulas, which relate permeability with porosity and specific surface of pore and cracks. Shown that Darcy Law is not mandatory condition for calculation of fluid flow velocity. This Law may be able for one porous subject geometry and not be able for another one. The role of permeability plays a ratio between of a cube of porosity and quadrat of pores and cracks specific surface.

We report a study of the suppressed decay B^- -> DK^-, D -> K^+\pi^-\pi^0, where D denotes either a D^0 or a \bar{D}^0 meson. The decay is sensitive to the CP-violating parameter \phi_3.

Using a data sample of 772 x 10^6 B\bar{B} pairs collected at the \Upsilon(4S) resonance with the Belle detector, we measure the ratio of branching fractions of the above suppressed decay to the favored decay B^- -> DK^-, D -> K^-\pi^+\pi^0.

Our result is R_{DK} = [1.98 +/- 0.62(stat.) +/- 0.24(syst.)] x 10^{-2}, which indicates the first evidence of the signal for this suppressed decay with a significance of 3.2 standard deviations. We measure the direct CP asymmetry between the suppressed B^- and B^+ decays to be A_{DK} = 0.41 +/- 0.30 (stat.) +/- 0.05 (syst.). We also report measurements for the analogous quantities R_{D\pi} and A_{D\pi} for the decay B^- -> D\pi^-, D -> K^+\pi^-\pi^0.
Software tools to automatically survey extended hydrogen bond motifs in a large set of crystal structures have recently become available [1,2].When applied to structures stored in the Cambridge Structural Database [3], these tools allow discrimination between common and unusual hydrogen bond motifs.Complete hydrogen bond networks can be described and common substructures can be identified by using the list of motifs present in each structure as a fingerprint [1].

The application of automated motif analysis will be demonstrated by discussing results obtained for amino acids, sulfonamides, sulfinamides and for cocrystals containing the corresponding functional groups.We will show that common packing arrangements in different forms can be readily identified by using motif fingerprints.

The results from such an analysis are particularly useful for the comparison of polymorphs and in the design of cocrystals.The presence of unusual hydrogen bond motifs will be related to polymorph stability and to unusual experimental conditions.The relevance of data from homomolecular crystals to the design of cocrystals will be assessed by comparing frequent motifs in crystals that contain the same donor and acceptor group either as part of a single molecule or in two components of a cocrystal.
This paper presents the recent experimental results on development of an optical frequency standard based on ultra cold magnesium atoms with relative frequency uncertainty and long term stability at the level of Δv/v <10−16.

We stabilized the frequency of our clock laser system at 655 THz to narrow Ramsey fringes in a time separated laser fields interacting with cooled Mg atoms localized in a magneto-optical trap (MOT). The intercombination line 1S0→3P1 was used as the reference for frequency stabilization.

The results of stabilization were studied with femtosecond comb based on Ti:Sa laser.
The Turkic peoples represent a diverse collection of ethnic groups defined by the Turkic languages. These groups have dispersed across a vast area, including Siberia, Northwest China, Central Asia, East Europe, the Caucasus, Anatolia, the Middle East, and Afghanistan. The origin and early dispersal history of the Turkic peoples is disputed, with candidates for their ancient homeland ranging from the Transcaspian steppe to Manchuria in Northeast Asia. Previous genetic studies have not identified a clear-cut unifying genetic signal for the Turkic peoples, which lends support for language replacement rather than demic diffusion as the model for the Turkic language’s expansion.

We addressed the genetic origin of 373 individuals from 22 Turkic-speaking populations, representing their current geographic range, by analyzing genome-wide high-density genotype data.

Most of the Turkic peoples studied, except those in Central Asia, genetically resembled their geographic neighbors, in agreement with the elite dominance model of language expansion. However, western Turkic peoples sampled across West Eurasia shared an excess of long chromosomal tracts that are identical by descent (IBD) with populations from present-day South Siberia and Mongolia (SSM), an area where historians center a series of early Turkic and non-Turkic steppe polities. The observed excess of long chromosomal tracts IBD (> 1cM) between populations from SSM and Turkic peoples across West Eurasia was statistically significant. Finally, we used the ALDER method and inferred admixture dates (∼9th–17th centuries) that overlap with the Turkic migrations of the 5th–16th centuries. Thus, our results indicate historical admixture among Turkic peoples, and the recent shared ancestry with modern populations in SSM supports one of the hypothesized homelands for their nomadic Turkic and related Mongolic ancestors.
Catalytic hydrotreatment is recognized as an efficient method to improve the properties of pyrolysis liquids (PO) to allow co-feeding with fossil fuels in conventional refinery units. The promising catalyst recipes identified so far are catalysts with high nickel contents (38 to 57 wt.%), promoted by Cu, Pd, Mo and/or a combination, and supported by SiO2, SiO2-ZrO2, SiO2-ZrO2-La2O3 or SiO2-Al2O3.

To gain insights into the reactivity of the pyrolytic sugar (PS) and pyrolytic lignin (PL) fraction of PO, hydrotreatment studies (350 °C, 120 bar H2 pressure (RT) for 4 h) were performed in a batch autoclave. Catalyst performance was evaluated by considering the product properties (H/C ratio, the charring tendency (TGA) and molecular weight distribution (GPC)) and the results were compared with a benchmark Ru/C catalyst. The fresh and spent catalysts after the hydrotreatment of the PS and PL fractions were characterized by elemental analysis, powder X-Ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM-EDX).

All Ni based catalysts gave products oils with a higher H/C compared to Ru/C. The Mo promoted catalyst performed best, giving a product with the highest H/C ratio (1.54) and the lowest TG residue (0.8 wt.% compared to 12 wt.% for the fresh PS). The results further revealed that the PS fraction is highly reactive and full conversion was achieved at 350 °C. In contrast, the PL fraction was rather inert, and only part of the PL fraction was converted. The results revealed that the use of PS as the feed leads to higher amounts of coke deposits on the catalysts, and higher levels of Ni agglomeration when compared to experiments with PL and pure PO. This proofs that proper catalyst selection for the PS fraction is of higher importance than for the PL fraction. The Mo promoted Ni catalysts showed the lowest amount of coke and the lowest tendency for Ni nanoparticle agglomeration compared to the monometallic Ni and bimetallic Ni-Cu catalysts.
The predissociation dynamics of lithium iodide (LiI) in the first excited A-state is investigated for molecules in the gas phase and embedded in helium nanodroplets, using femtosecond pump-probe photoionization spectroscopy. In the gas phase, the transient Li+ and LiI+ ion signals feature damped oscillations due to the excitation and decay of a vibrational wave packet. Based on high-level ab initio calculations of the electronic structure of LiI and simulations of the wave packet dynamics, the exponential signal decay is found to result from predissociation predominantly at the lowest avoided X-A potential curve crossing, for which we infer a coupling constant V=650(20) reciprocal cm. The lack of a pump-probe delay dependence for the case of LiI embedded in helium nanodroplets indicates fast droplet-induced relaxation of the vibrational excitation.

IgA anti-CD74 can be a promising marker for diagnosis, assessment of activity and prognosis for ankylosing spondylitis. The aim of the study was to determine the level of IgA anti-CD74 in patients with ankylosing spondylitis and to evaluate its relationships with ankylosing spondylitis activity and carriership of genetic alleles. Materials and methods . In 48 patients with a reliable diagnosis of ankylosing spondylitis, aged 18 to 69 years were measured the ASDAScrp, BASDAI, level of highly sensitive С-reactive protein, concentration of IgA anti-CD74. The polymorphisms of the genes interleukin (IL)-17A197 a/g, IL-17F7 histidine (His) / arginine (Arg), IL-17F11139 c/g, TNF-a-863, TNFα-308, TNFα-238, IL-1B-31, IL- 4-590, IL-6-174, IL-10-1082, IL-10-592, vascular endothelial growth factor (VEGF)-2578, VEGF-936, matrix metalloproteinase (MMP)2-1306, MMP3-5A6A, MMP9-1562, HLA-B27 were evaluated in their relationships with AS activity and IgA anti-CD74 levels. Results . The mean age of patients was 45.1±14.2 years, male - 72.9%, psoriasis - 10.4%, IBD - 2.1%, BASDAI -2.99±0.28, ASDAS - 2.29±0.16, CRP - 6.5±1.65 mg/L, IgA эпй-СВ74 - 18.6±1.73 U/mL (72.9% of the patients with >12 U/mL). The relationship between an increase in concentration of IgA anti-CD74 and ASDAScrp, BASDAI activity indices, between an increase in the level of CRP and the presence of the IL-17A genotype heterozygous for the AA allele (r=0.965) was determined. CRP did not demonstrate the relationship with the BASDAI. An association of IL-17F-11139 СС and the presence of psoriasis (r=0.870) was established. 93.8% of patients with ankylosing spondylitis were carriers of the homozygous histidine allele IL-17F7 (his/his) and the TNF238 allele (GG). Conclusions . The increase in anti-CD74 IgA level was found in 72.9% of patients with ankylosing spondylitis receiving inhibitors of TNF-a and NSAIDs and associated with clinical and laboratory indicators of ankylosing spondylitis activity and with carriage of the homozygous histidine allele IL-17F7 (his/his) detected in 93.8% of patients. Carriage of TNF-238 GG; TNF-863 CC; HLA-B27; TNF-308 GG; IL-4-590 CC; IL-6-174 CG; MMP9-1562 CC; MMP9-1562 CC; VEGF- 936 CC alleles was not associated with an increase in concentration of IgA anti-CD74. CRP demonstrated an association with IL-17A-197 AA (r=0.965) detected in 29.2% of patients with no correlation with the clinical ankylosing spondylitis activity in patients receiving treatment with iTNF-α and NSAIDs.
The qualitative properties of solutions of a hereditary model of motion of aqueous solutions of polymers, its modification in the limiting case of short relaxation times, and a similar second grade fluid model are studied. Unsteady shear flows are considered. In the first case, their properties are similar to those of motion of a usual viscous fluid. Other models can include weak discontinuities, which are retained in the course of fluid motion. Exact solutions are found by using the group analysis of the examined systems of equations. These solutions describe the fluid motion in a gap between coaxial rotating cylinders, the stagnation point flow, and the motion in a half-space induced by plane rotation (analog of the Karman vortex). The problem of motion of an aqueous solution of a polymer in a cylindrical tube under the action of a streamwise pressure gradient is considered. In this case, a flow with straight-line trajectories is possible (analog of the Hagen-Poiseuille flow). In contrast to the latter, however, the pressure in the flow considered here depends on all three spatial variables.
The exact solution of the Schrödinger equation for the one-dimensional system of interacting particles with linear dispersion law in an arbitrary external field is found. The solution is reduced to two groups of particles moving with constant velocities in the opposite directions with a fixed distance between the particles in each group.

The problem is applied to the edge states of the 2D topological insulator.
