Purpose. This paper aims to examine the short stories On the Night before Easter, Student and Bishop by A. P. Chekhov, which the author unites into an individual Easter story cycle based on their common spiritual and moral challenges and particular calendar time – the Easter. Results. The landscape in On the Night before Easter is in consonance with thoughts and inner world of the storyteller, novitiate Hieronimus and idling folk. By depicting nature, Chekhov manages to antithesize ‘spiritual’ and ‘fleshly’, ‘true’ and ‘borrowed’ knowledge. Easter motifs and attributes also contribute to this atmosphere. In this short story, Chekhov portrays the Church representatives as common people, which results in powerful emotional feedback from the readers. The main idea of the Easter short story Student – the issue of human memory, belief and time. At Easter the protagonist – Ivan Velikopolskii – has ‘resurrected’, feels a desire to live and enjoy his life. An accidental meeting with two women at the campfire on Great Friday allows him to acknowledge the importance of being involved in someone else’s suffering and uniting with people. In Bishop, one of Chekhov’s ‘top’ works, Easter motifs, attributes and landscape sketches help the writer to reveal the protagonist’s inner world and get through the author’s idea of the value of human life. This story finalizes many motifs and themes typical for Chekhov’s mature works. Conclusion. The works represented in this article are united by common themes, plots and Easter motifs and multiple psychological details embedded in the narration, which depict the inner world of characters. Landscape descriptions correlating with the characters’ spiritual state also play a significant role.
Metal-oxide thin-film transistors (TFTs) have been implanted for a display panel, but further mobility improvement is required for future applications. In this study, excellent performance was observed for top-gate coplanar binary SnO2 TFTs, with a high field-effect mobility (μFE) of 136 cm2/Vs, a large on-current/off-current (ION/IOFF) of 1.5 × 108, and steep subthreshold slopes of 108 mV/dec. Here, μFE represents the maximum among the top-gate TFTs made on an amorphous SiO2 substrate, with a maximum process temperature of ≤ 400 °C. In contrast to a bottom-gate device, a top-gate device is the standard structure for monolithic integrated circuits (ICs). Such a superb device integrity was achieved by using an ultra-thin SnO2 channel layer of 4.5 nm and an HfO2 gate dielectric with a 3 nm SiO2 interfacial layer between the SnO2 and HfO2. The inserted SiO2 layer is crucial for decreasing the charged defect scattering in the HfO2 and HfO2/SnO2 interfaces to increase the mobility. Such high μFE, large ION, and low IOFF top-gate SnO2 devices with a coplanar structure are important for display, dynamic random-access memory, and monolithic three-dimensional ICs.
Heading time is an important agronomic trait affecting the adaptability and productivity of common wheat.

In this study, 95 common wheat varieties from Russia and the late-maturing breeding line ‘Velut’ were tested for allelic diversity of genes having the strongest effect on heading. In this research, allelic variation at the Ppd-D1, Vrn-A1, Vrn-B1, Vrn-D1, and Vrn-B3 loci was tested. The analysis of the sequences showed the recent insertion of a retrotransposon homologous to the LTR retrotransposon (RLX_Hvul_Dacia_ RND-1) in the Vrn-B3d allele. Analysis of the gene expression of two groups of lines differing by the Vrn-B3 alleles (Vrn-B3d or vrn-B3) from the F2 population with ‘Velut’ as a parental line did not reveal a significant difference in the expression level between the groups.

The Vrn-B1 and Vrn-B3 loci provided the largest contribution to genetic diversity. We found two novel allelic variants of the Vrn-B3 gene in the studied varieties. Ten varieties carried a 160 bp insertion in the promoter region, and the breeding line ‘Velut’ carried a 1617 bp insertion. These alleles were designated Vrn-B3e and Vrn-B3d, respectively. Plants with the Vrn-B3e and the ‘Velut’ line with the Vrn-B3d allele headed later than the plants with the wild-type allele; among these plants, ‘Velut’ is the latest maturing wheat variety. Additional research is required to study the reasons for the late maturation of the ‘Velut’ line. However, the studied wheat varieties could be used as a potential source of natural variation in genes controlling heading times.
A finite group is said to be weakly separable if every algebraic isomorphism between two $S$-rings over this group is induced by a combinatorial isomorphism. In the paper we prove that every abelian weakly separable group belongs to one of several explicitly given families only.
The concept of an imaging-type 3D spin detector, based on the combination of spin-exchange interactions in the ferromagnetic (FM) film and spin selectivity of the electron–photon conversion effect in a semiconductor heterostructure, is proposed and demonstrated on a model system. This novel multichannel concept is based on the idea of direct transfer of a 2D spin-polarized electron distribution to image cathodoluminescence (CL).

The detector is a hybrid structure consisting of a thin magnetic layer deposited on a semiconductor structure allowing measurement of the spatial and polarization-dependent CL intensity from injected spin-polarized free electrons. The idea is to use spin-dependent electron transmission through in-plane magnetized FM film for in-plane spin detection by measuring the CL intensity from recombined electrons transmitted in the semiconductor. For the incoming electrons with out-of-plane spin polarization, the intensity of circularly polarized CL light can be detected from recombined polarized electrons with holes in the semiconductor. In order to demonstrate the ability of the solid-state spin detector in the image-type mode operation, a spin detector prototype was developed, which consists of a compact proximity focused vacuum tube with a spin-polarized electron source [ p -GaAs(Cs,O)], a negative electron affinity (NEA) photocathode and the target [semiconductor heterostructure with quantum wells also with NEA]. The injection of polarized low-energy electrons into the target by varying the kinetic energy in the range 0.5–3.0 eV and up to 1.3 keV was studied in image-type mode. The figure of merit as a function of electron kinetic energy and the target temperature is determined.

The spin asymmetry of the CL intensity in a ferromagnetic/semiconductor (FM-SC) junction provides a compact optical method for measuring spin polarization of free-electron beams in image-type mode. The FM-SC detector has the potential for realizing multichannel 3D vectorial reconstruction of spin polarization in momentum microscope and angle-resolved photoelectron spectroscopy systems.
Oxidative reactions that are catalyzed by cytochromes P450 1A (CYP1A) lead to formation of carcinogenic derivatives of arylamines and polycyclic aromatic hydrocarbons (PAHs), such as the widespread environmental pollutant benzo(α)pyrene (BP). These compounds upregulate CYP1A at the transcriptional level via an arylhydrocarbon receptor (AhR)-dependent signaling pathway. Because of the involvement of AhR-dependent genes in chemically induced carcinogenesis, suppression of this signaling pathway could prevent tumor formation and/or progression.

Here we show that menadione (a water-soluble analog of vitamin K3) inhibits BP-induced expression and enzymatic activity of both CYP1A1 and CYP1A2 in vivo (in the rat liver) and BP-induced activity of CYP1A1 in vitro. Coadministration of BP and menadione reduced DNA-binding activity of AhR and increased DNA-binding activity of transcription factors Oct-1 and CCAAT/enhancer binding protein (C/EBP), which are known to be involved in negative regulation of AhR-dependent genes, in vivo. Expression of another factor involved in downregulation of CYP1A—pAhR repressor (AhRR)—was lower in the liver of the rats treated with BP and menadione, indicating that the inhibitory effect of menadione on CYP1A is not mediated by this protein. Furthermore, menadione was well tolerated by the animals: no signs of acute toxicity were detected by visual examination or by assessment of weight gain dynamics or liver function.

Taken together, our results suggest that menadione can be used in further studies on animal models of chemically induced carcinogenesis because menadione may suppress tumor formation and possibly progression.
By a proper cover of a finite group G we mean an extension of a nontrivial finite group by G. Our purpose is to show that a proper cover of a finite simple group L of Lie type always contains an element whose order differs from the element orders of L provided that the Lie rank of L is sufficiently large.
The Jurassic and Cretaceous paleohydrogeology of the Arctic regions of Western Siberia includes three hydrogeological cycles: Induan-Sinemurian, Pliensbachian-Cenomanian, Turonian-Serravallian.

The paper presents results of the paleohydrological reconstructions of Jurassic and Cretaceous deposits. In the Triassic-Early Jurassic and Berriman-Cenomanian, the continental regime of sedimentation was prevalent within the study area, along with the processes of infiltration of fresh meteoric waters mainly hydrocarbonate calcium in composition with the TDS value not exceeding 5 g/dm3. Marine sedimentation conditions were dominant during the Pliensbachian-Hauterivian and Turonian-Bartonian elision stages, when the processes of sedimentation were accompanied by syngenetic burial of sodium chloride waters, locally rich in magnesium, with the TDS value reaching 35 g/dm3 in the deepest parts of the marine basin existing in the Volgian time.

Modern chemistry of groundwaters of Jurassic and Cretaceous deposits in the Arctic regions of Western Siberia is a product of long-term geological evolution of the 'water-rock-gas-OM' system.
Results of dedicated Monte Carlo simulations of beam-induced background (BIB) in the ATLAS experiment at the Large Hadron Collider (LHC) are presented and compared with data recorded in 2012. During normal physics operation this background arises mainly from scattering of the 4 TeV protons on residual gas in the beam pipe. Methods of reconstructing the BIB signals in the ATLAS detector, developed and implemented in the simulation chain based on the FLUKA Monte Carlo simulation package, are described. The interaction rates are determined from the residual gas pressure distribution in the LHC ring in order to set an absolute scale on the predicted rates of BIB so that they can be compared quantitatively with data. Through these comparisons the origins of the BIB leading to different observables in the ATLAS detectors are analysed. The level of agreement between simulation results and BIB measurements by ATLAS in 2012 demonstrates that a good understanding of the origin of BIB has been reached.
We demonstrate the stabilization of two-dimensional nonlinear wave patterns by means of a dissipative confinement potential.

Our analytical and numerical analysis, based on the generalized dissipative Gross-Pitaevskii equation, makes use of the close analogy between the dynamics of a Bose-Einstein condensate and that of mode-locked fiber laser, operating in the anomalous dispersion regime. In the last case, the formation of stable two-dimensional patterns corresponds to spatiotemporal mode locking, using dissipation-enhanced mode cleaning.

We analyze the main scenarios of pattern destabilization, varying from soliton dissolution to its splitting and spatiotemporal turbulence, and their dependence on graded dissipation.
The current state of the Russian and foreign regulatory framework for off-label prescription of medicines is presented in the article. The existing problems of this specific drug therapy and possible solutions are described. Unfortunately, there are some gaps in the Russian legislation regarding the off-label medication use.

Based on the clinical reality, in some cases, the “off-label” drugs prescription can be justified by the clinical condition of the patient, the lack of alternative approved drugs, and the availability of published scientific data that create the prerequisites for the effectiveness of this approach.

When off-label drug prescribing as a forced measure, the doctor must provide a rationale for this prescription in the medical documentation, the conclusion of the consultation (with the participation of relevant specialists and the clinical pharmacologist) or the medical commission (with the participation of the administration representative), and the written informed consent of the patient or his legal representative. This information should be actively communicated to doctors in order to increase their legal literacy and prevent possible negative and legal consequences.
We provide a Finslerian extension of the Schwarzschild metric based on heuristic arguments.The proposed metric asymptotically approaches not the Minkowski space-time but the Bogoslovsky locally anisotropic spacetime which arises naturally as a deformation of very special relativity.
Contrary to almost standard opinion that the X(3872) resonance is the D^{*0}\bar D^0+c.c. molecule or the qc\bar q\bar c four-quark state

we discuss the scenario where the X(3872)resonance is the c\bar c = \chi_{c1}(2P) charmonium which "sits on" the D^{*0}\bar D^0 threshold. We explain the shift of the mass of the X(3872) resonance with respect to the prediction of a potential model for the mass of the \chi_{c1}(2P) charmonium by the contribution of the virtual D^*\bar D+c.c. intermediate states into the self energy of the X(3872) resonance. This allows us to estimate the coupling constant of the X(7872) resonance with the D^{*0}\bar D^0 channel, the branching ratio of the X(3872) \to D^{*0}\bar D^0 + c.c. decay

and the branching ratio of the X(3872) decay into all non-D^{*0}\bar D^0 + c.c. states. We predict a significant number of unknown decays of X(3872) via two gluon:X(3872)\to gluon\ gluon\to hadrons. We suggest a physically clear program of experimental researches for verification of our assumption.

Synthetic recombination form RS7 (BBAAUS), in which the first two genomes, A and B, originate from common wheat, and the third recombinant genome consists of Aegilops speltoides (S) and Ae. umbellulata (U) chromosomes, was obtained from crossing synthetic forms Avrodes (BBAASS) and Avrolata (BBAAUU). Resistant to leaf rust, yellow rust and powdery mildew, introgression lines have been obtained from backcrosses with the susceptible varieties of common wheat Krasnodarskaya 99, Fisht and Rostislav. PCR analysis showed the presence of amplification fragments with marker SCS421 specific for the Lr28 gene in the line 4991n17. The cytological study (С-banding and FISH) of 14 lines has revealed chromosomal modifications in 12 of them. In most cases, the lines carry translocations from Ae. speltoides, which were identified in chromosomes 1D, 2D, 3D, 2B, 4B, 5B and 7B. Also, lines with the substituted chromosomes 1S (1B), 4D (4S), 5D (5S) and 7D (7S) were identified. Lines that have genetic material from Ae. speltoides and Ae umbellulata at once were revealed. In the line 3379n14, translocations in the short arm of chromosome 7D from Ae. umbellulata and chromosomes 5BL, 1DL, 2DL from Ae. speltoides were revealed. The line 4626p16 presumably has a translocation on the long arm of chromosome 2D from Ae. umbellulata and the T7SS.7SL-7DL translocation from Ae. speltoides. The T1DS.1DL-1SL and T3DS.3DL-3SL translocations from Ae. speltoides, and T2DS.2DL-2UL and T7DL.7DS-7US from Ae. umbellulata have been obtained for the first time. These lines may carry previously unidentified disease resistance genes and, in particular, leaf rust resistance genes from Ae. speltoides and Ae. umbellulata.
Among the hyperpolarization techniques geared toward in vivo magnetic resonance imaging, parahydrogen-induced polarization (PHIP) shows promise due to its low cost and fast speed of contrast agent preparation. The synthesis of 13C-labeled, unsaturated precursors to perform PHIP by side arm hydrogenation has recently opened new possibilities for metabolic imaging owing to the biological compatibility of the reaction products, although the polarization transfer between the parahydrogen-derived protons and the 13C heteronucleus must yet be better understood, characterized, and eventually optimized.

In this realm, a new experimental strategy incorporating pulse-programmable magnetic field sweeping and in situ detection has been developed. The approach is evaluated by measuring the 13C polarization of ethyl acetate-1-13C, i.e., the product of pairwise addition of parahydrogen to vinyl acetate-1-13C, resulting from zero-crossing magnetic field ramps of various durations, amplitudes, and step sizes.

The results demonstrate (i) the profound effect these parameters have on the 1H to 13C polarization transfer efficiency and (ii) the high reproducibility of the technique.
It has been shown that, with the administration of cuprizone, the amount of myelin in a number of structures of white and gray matter and the level of neurogenesis decrease, while the level of oligodendrogenesis increases.

In this research, a cuprizone model of multiple sclerosis (MS) was used to study oligodendrogenesis and neurogenesis in remyelination.

The withdrawal of cuprizone leads to the restoration of myelin content, the reduction of the excessive production of oligodendrocytes and to the restoration of the number of neurons to control values. The negative correlation between the number of oligodendrocyte precursors (OPCs) and the degree of demyelination of the corpus callosum indicates migration of OLG precursors from the subventricular zone (SVZ) to the structure during demyelination.
The novel macroporous carbon-mineral Sapropel supports were obtained from lacustrine sapropel silts of freshwater lakes by annealing of semi-coke in the inert atmosphere. The specific surface area of these supports varied from 10 to 100 m2/g, the total pore volume from 0.3 cm3/g till 1.6 cm3/g; macropores of diameters more than 2 µm were predominating.

The Sapropel supports were studied for the adsorption/adhesion of enzymatic active substances, such as whole bacterial cells, and invertase-active fully destroyed baker's yeast cells (autolysates), and purified enzyme nitrilase. The heterogeneous biocatalysts with required enzymatic activity were prepared and their properties were studied in the corresponding bioconversion processes.

The invertase-active biocatalysts exhibited high activity, 120–135 U/g, and stability; the half-times of their inactivation (t½) were more than 1000 h in the continuous process of sucrose hydrolysis at 50°C. The nitrilase-active biocatalysts for "green" chemistry of nitriles possessed high activity, 350–500 U/g, and the t½ were estimated to be more than 100 h in the periodic process of hydration of acrylonitrile to acrylic acid at 22°C.

The two-phase gas-liquid flow regimes in the horizontal rectangular microchannel using the high-speed video camera and dual-laser scanning were studied.

Experiments were carried out in the microchannel with cross section 217x370 μm for the water-nitrogen mixture. The T-shaped mixer was used for gas-liquid flow formation. The total pressure drop was measured in the microchannel taking into account the distribution of the gas and liquid bridges.

The influence of T-shaped entrance on the length of a gas and liquid bridges in the microchannel was established.
Using a data sample of $980\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of ${e}^{+}{e}^{\ensuremath{-}}$ annihilation data taken with the Belle detector operating at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider, we report the results of a study of excited ${\mathrm{\ensuremath{\Xi}}}_{c}$ states that decay, via the emission of photons and/or charged pions, into ${\mathrm{\ensuremath{\Xi}}}_{c}^{0}$ or ${\mathrm{\ensuremath{\Xi}}}_{c}^{+}$ ground state charmed-strange baryons. We present new measurements of the masses of all members of the ${\mathrm{\ensuremath{\Xi}}}_{c}^{\ensuremath{'}}$, ${\mathrm{\ensuremath{\Xi}}}_{c}(2645)$, ${\mathrm{\ensuremath{\Xi}}}_{c}(2790)$, ${\mathrm{\ensuremath{\Xi}}}_{c}(2815)$, and ${\mathrm{\ensuremath{\Xi}}}_{c}(2980)$ isodoublets, measurements of the intrinsic widths of those that decay strongly, and evidence of previously unknown transitions.
Filling of single-walled carbon nanotubes (SWCNTs) and extraction of the encapsulated species from their cavities are perspective treatments for tuning the functional properties of SWCNT-based materials. Here, we have investigated sulfur-modified SWCNTs synthesized by the ampoule method. The morphology and chemical states of carbon and sulfur were analyzed by transmission electron microscopy, Raman scattering, thermogravimetric analysis, X-ray photoelectron and near-edge X-ray absorption fine structure spectroscopies. Successful encapsulation of sulfur inside SWCNTs cavities was demonstrated. The peculiarities of interactions of SWCNTs with encapsulated and external sulfur species were analyzed in details. In particular, the donor–acceptor interaction between encapsulated sulfur and host SWCNT is experimentally demonstrated. The sulfur-filled SWCNTs were continuously irradiated in situ with polychromatic photon beam of high intensity. Comparison of X-ray spectra of the samples before and after the treatment revealed sulfur transport from the interior to the surface of SWCNTs bundles, in particular extraction of sulfur from the SWCNT cavity. These results show that the moderate heating of filled nanotubes could be used to de-encapsulate the guest species tuning the local composition, and hence, the functional properties of SWCNT-based materials.
