While performing vegetation surveys in the southern part of the Lena delta, a new species of Carex from section Phacocystis has been found. Morphologically, Carex delongii sp. nov. is most close to C. cespitosa and C. minuta but differs from the former in smaller inflorescences, shorter pistillate spikes, narrow and soft leaves, oblong-ovoid (vs. ovoid) utricles; from the latter, it is distinguished by having smaller spikes and larger utricles.

This relationship is also confirmed by molecular data.

A detailed description of Carex delongii, its comparison with related species, illustrations, characteristics of habitat and phylogenetic position are reported.
A strong spin-orbit interaction leads to a Rashba-type splitting of the bulk bands of BiTeCl, which results in toroidal Fermi surfaces with distinct spin structures depending on the chemical potential.

Here, we present spin- and angle-resolved photoelectron spectroscopy measurements of the three-dimensional spin-orbit split state at the top of the valence band. Its polarization is systematically studied in dependence of the photon energy and compared to ab initio calculations of the initial state.

The measured spin orientation is in plane to the (0001) surface and perpendicular to the momentum, independently of the photon energy.
An infinite permutation is a linear ordering of the set of non-negative integers. Generally, the properties of infinite permutations analogous to those of infinite words show some resemblances and some differences between permutations and words.

In this paper, we define maximal pattern complexity for infinite permutations and show that this complexity function is ultimately constant if and only if the permutation is ultimately periodic.

Then we characterize the non-periodic permutations of minimal complexity (equal to n) and find that they all are constructed with the use of Sturmian words.
Basic solutions of the theory of weak turbulence, the so-called Kolmogorov–Zakharov solutions, are shown to be relevant to the results of the simulations.

Results of extensive simulations of swell evolution within the duration-limited setup for the kinetic Hasselmann equation for long durations of up to 2 × 106 s are presented. Features of self-similarity of wave spectra are detailed and their impact on methods of ocean swell monitoring is discussed.

Essential drop in wave energy (wave height) due to wave–wave interactions is found at the initial stages of swell evolution. At longer times, wave–wave interactions are responsible for a universal angular distribution of wave spectra. Weak power-law attenuation of swell within the Hasselmann equation is not consistent with results of ocean swell tracking from satellite data. The relatively fast weakening of wave–wave interactions makes the swell evolution sensitive to other effects. In particular, coupling with locally generated wind waves can force the swell to grow in relatively light winds.
Based on the molecular-dynamic simulation of the impact of a solid ball on the surface of polycrystalline copper

a method for calculating the dynamic hardness of nanocrystalline materials is proposed. It is proposed to carry out the calculation of hardness by dividing the impact work by the squeezed volume. It is shown that this expression of dynamic hardness is consistent with Meyer hardness in the case of quasistatic indentation.

As a result of this simulation, it is shown that under conditions when the diameter of the impactor decreases and approaches the crystal lattice constant of the target, the dynamic hardness increases. Also, in the calculations, the impactor density varied approximately twice, which was equal to the density of steel and the density of tungsten carbide. For a striker diameter of 5 nm, dynamic hardness increases with the speed of the striker and does not depend on its density.
The work is devoted to numerical simulation of the dynamics of nonlinear periodic waves on the surface of freely flowing liquid film realized with the use of the previously discovered symmetry of model equations. The calculation results have been presented for the dynamics of amplitudes of significant harmonics and for the wave surface evolution. They prove to be in good agreement with previously calculated steady-state traveling solutions obtained on the full and the reduced bases. In addition, the work has identified intervals of wavenumbers in which the evolution of perturbations with small initial amplitude leads to a wave signal periodically changing in time rather than to the steady-state traveling solution.
A vast amount of SNPs derived from genome-wide association studies are represented by non-coding ones, therefore exacerbating the need for effective identification of regulatory SNPs (rSNPs) among them. However, this task remains challenging since the regulatory part of the human genome is annotated much poorly as opposed to coding regions.

Here we describe an approach aggregating the whole set of ENCODE ChIP-seq data in order to search for rSNPs, and provide the experimental evidence of its efficiency. Its algorithm is based on the assumption that the enrichment of a genomic region with transcription factor binding loci (ChIP-seq peaks) indicates its regulatory function, and thereby SNPs located in this region are more likely to influence transcription regulation. To ensure that the approach preferably selects functionally meaningful SNPs, we performed enrichment analysis of several human SNP datasets associated with phenotypic manifestations. For experimental verification, 40 SNPs falling into overlapping regions of at least 7 TF binding loci were selected from OMIM. The effect of SNPs on the binding of the DNA fragments containing them to the nuclear proteins from four human cell lines (HepG2, HeLaS3, HCT-116, and K562) has been tested by EMSA.

It was shown that all samples are significantly enriched with SNPs falling into the regions of multiple ChIP-seq peaks as compared with the randomly selected SNPs. A radical change in the binding pattern has been observed for 29 SNPs, besides, 6 more SNPs also demonstrated less pronounced changes. Taken together, the results demonstrate the effective way to search for potential rSNPs with the aid of ChIP-seq data provided by ENCODE project.
A numerical simulation of a supersonic (M∞ = 7) flow around a cylinder with a front gas-permeable porous insert at a zero angle of attack was carried out using three-dimensional skeleton models of a highly porous cellular material made of non-intersecting hard spheres with a regular and chaotic arrangement of pores. A comparative analysis of these skeleton models with different spatial arrangement and pore size showed a weak influence of the structure of skeleton models on the resistance of a cylinder with a front gas-permeable insert. The computed data of the drag coefficient are compared with the results of tube experiments.
Double complex salts can be used as precursors for the preparation of bimetallic alloys of high-melting metals upon temperatures less than 600 ºC.The crystals of the title compounds have been synthesized by mixing together the aqueous solutions of complex salts containing [M A (NH 3 )Cl] 2+ (M A = Co, Rh, Ir) cations and MoO 4 2-or WO 4 2-anions.Single crystal X-ray diffraction analysis was carried out on a Bruker X8 APEX CCD-based diffractometer with MoKα-radiation at 150 K.All involved complex salts are isostructural and crystallize in the orthorhombic space group Pnma (Z = 4).The compounds have the island crystal structures with the isolated ions.Thermal decomposition in the reducing atmosphere of the double complex salts occurs at temperatures 100-600° K.The XRD analysis of the thermolysis products was performed on an ARL X'TRA diffractometer with CuKα-radiation and shows the solid solutions formation of title metals with particle sizes less than 50 nm.The final products phase composition is shown to depend on phase diagrams of the respective bimetallic systems.Owing to the fact that those complex salts are isostructural it is possible to prepare the solid solutions and the triple and quadruple alloys after their decomposition.
. We study soliton collisions in the Dyachenko–Zakharov equation for the envelope of gravity waves in deep water. The numerical simulations of the soliton interactions revealed several fundamentally different effects when compared to analytical two-soliton solutions of the nonlinear Schrodinger equation. The relative phase of the solitons is shown to be the key parameter determining the dynamics of the interaction. We find that the maximum of the wave field can significantly exceed the sum of the soliton amplitudes. The solitons lose up to a few percent of their energy during the collisions due to radiation of incoherent waves and in addition exchange energy with each other. The level of the energy loss increases with certain synchronization of soliton phases. Each of the solitons can gain or lose the energy after collision, resulting in increase or decrease in the amplitude. The magnitude of the space shifts that solitons acquire after collisions depends on the relative phase and can be either positive or negative.
Biological activity of antisense oligonucleotides (asON), especially those with a neutral backbone, is often attenuated by poor cellular accumulation. In the present proof-of-concept study, we propose a novel delivery system for asONs which implies the delivery of modified antisense oligonucleotides by so-called transport oligonucleotides (tON), which are oligodeoxyribonucleotides complementary to asON conjugated with hydrophobic dodecyl moieties. Two types of tONs, bearing at the 5′-end up to three dodecyl residues attached through non-nucleotide inserts (TD series) or anchored directly to internucleotidic phosphate (TP series), were synthesized. tONs with three dodecyl residues efficiently delivered asON to cells without any signs of cytotoxicity and provided a transfection efficacy comparable to that achieved using Lipofectamine 2000. We found that, in the case of tON with three dodecyl residues, some tON/asON duplexes were excreted from the cells within extracellular vesicles at late stages of transfection. We confirmed the high efficacy of the novel and demonstrated that MDR1 mRNA targeted asON delivered by tON with three dodecyl residues significantly reduced the level of P-glycoprotein and increased the sensitivity of KB-8-5 human carcinoma cells to vinblastine. The obtained results demonstrate the efficacy of lipophilic oligonucleotide carriers and shows they are potentially capable of intracellular delivery of any kind of antisense oligonucleotides.
On structures in hypergraphs of models of a theory Hypergraphs of models of a theory are derived objects allowing to obtain an essential structural information about both given theories and related semantic objects including graph ones.

In the present paper we define and study structural properties of hypergraphs of models of a theory including lattice ones.

Characterizations for the lattice properties of hypergraphs of models of a theory, as well as for structures on sets of isomorphism types of models of a theory, are given.
FRAXopathies are caused by the expansion of the CGG repeat in the 5′UTR of the FMR1 gene, which encodes the protein responsible for the synthesis of FMRP. This mutation leads to dramatic changes in FMRP expression at both the mRNA and protein levels. Evidence is emerging that changes in FMR1 mRNA expression can lead to the dysregulation of the miRNAs that target its 3′UTR.

In the present work, B-lymphocyte cell lines obtained from patients with FRAXopathies were used, and a wide variety of FMR1 gene activities were observed, allowing the identification of the relationships between FMR1 dysregulation and miRNA activity. We studied the expression levels of eight miRNAs that target the FMR1 gene. To prove the interaction of the studied miRNAs with FMR1, a plasmid was constructed that possesses three primary structures: the miRNA gene, with expression driven by an inducible promoter; a constitutively expressed FusionRed reporter; and an eGFP reporter followed by the 3′UTR of the FMR1 gene.

We evaluated changes in miRNA expression in response to alterations in FMR1 gene activity in a model cell line as well as interactions with some miRNAs with the FMR1 3′UTR.
Liquid phase pentanoic acid hydrogenation in decane as a solvent (180 ºC, hydrogen pressure 25 bar) was studied over monometallic Ir and bimetallic Ir-Re catalysts supported on alumina, ceria and zirconia, as well as carbon support Sibunit.Before catalytic test all catalysts were preliminary treated in Н 2 at 415 ºC during 5 h.An XPS study revealed predominant metallic state for Ir in studied catalysts while Re was partially oxidized.Conversion of pentanoic acid changed in the row Ir/CeO 2 < Ir/ZrO 2 < IrRe/ZrO 2 < IrRe/Al 2 O 3 ~ IrRe/C.Selectivity to pentanol was elevated over bimetallic catalysts in the sequence Ir/Al 2 O 3 < Ir/CeO 2 ~ Ir/ZrO 2 < IrRe/ZrO 2 < IrRe/Al 2 O 3 ~ IrRe/C.It was shown that doping of Ir with Re gives a rise of pentanoic acid conversion and selectivity to pentanol in the absence of byside decarboxylation reaction.A series of the most active catalyst IrRe/Al 2 O 3 was prepared varying Ir particle size from 0.8 to 1.7 nm as verified by TEM.Both pentanoic acid conversion and selectivity to pentanol over IrRe/Al 2 O 3 catalyst increased with an increase of mean Ir particle size.
The photocatalytic activity of TiO2 depends on numerous factors, such as the chemical potential of electrons, charge transport properties, band-gap energy, and concentration of surface-active sites. A lot of research has been dedicated to determining the properties that have the most significant influence on the photocatalytic activity of semiconductors.

Here, we demonstrated that the activity of TiO2 in the gas-phase reduction of CO2 is governed mainly by the desorption rate of the reaction intermediates and final products.

This indicates that the specific surface area of TiO2 and binding strength of reaction intermediates and products are the main factors affecting the photocatalytic activity of TiO2 in the investigated process. Additionally, it was shown that rutile exhibits higher photocatalytic activity than anatase/rutile mixtures mainly due to its high efficiency in the visible portion of the electromagnetic spectrum.
Cesium adsorption on $(2\ifmmode\times\else\texttimes\fi{}4)$-GaAs(001) was studied by photoemission and low-energy electron diffraction. The different Cs-induced changes of $\text{As}\text{ }3d$ and $\text{Ga}\text{ }3d$ core-level spectra show that charge transfer is almost complete for Ga surface sites, but is negligible to surface As at a coverage ${\ensuremath{\Theta}}_{\text{Cs}}<0.3\text{ }\text{ML}$. The situation becomes opposite for ${\ensuremath{\Theta}}_{\text{Cs}}>0.3\text{ }\text{ML}$, at which transfer occurs to As but no longer to Ga. Charge transfer to As atoms leads to surface disordering and destabilization and induces surface conversion from As-rich to Ga-rich $(4\ifmmode\times\else\texttimes\fi{}2)$-GaAs(001) surface after annealing at a reduced temperature of $450\text{ }\ifmmode^\circ\else\textdegree\fi{}\text{C}$.
Spoof localized surface plasmon resonances (LSPRs) in the THz range are promising for bio-sensing and spectroscopy.

Using long spiral grooves allows improving the surface mode confinement of LSPRs in the long-wavelength region. Our numerical simulations of sub-wavelength spiral gold disks in the range of 0.04–6 THz have shown that in case of Drude conductivity and normal incidence of EM radiation only the first- and second-order dipole localized surface plasmon resonances (LSPRs) are excited. High order resonances arise at inclined incidence.

The spectra and 2D distributions of the EM field at the resonant frequencies depend on the number of spiral arms and symmetry of the spiral structure.
A common feature of domestic animals is tameness-i.e., they tolerate and are unafraid of human presence and handling. To gain insight into the genetic basis of tameness and aggression, we studied an intercross between two lines of rats (Rattus norvegicus) selected over >60 generations for increased tameness and increased aggression against humans, respectively.

We measured 45 traits, including tameness and aggression, anxiety-related traits, organ weights, and levels of serum components in >700 rats from an intercross population. Using 201 genetic markers, we identified two significant quantitative trait loci (QTL) for tameness.

These loci overlap with QTL for adrenal gland weight and for anxiety-related traits and are part of a five-locus epistatic network influencing tameness. An additional QTL influences the occurrence of white coat spots, but shows no significant effect on tameness. The loci described here are important starting points for finding the genes that cause tameness in these rats and potentially in domestic animals in general.
Silica nanoparticles (SNPs) doped by hexanuclear molybdenum cluster complexes [{Mo6X8}L6]n (X = Cl, Br, or I; L = various inorganic or organic ligands) have been recently suggested as materials with high potential for biomedical applications due to both their outstanding photoluminescence properties and their ability to efficiently generate singlet oxygen upon photoirradiation. However, no studies were undertaken so far to prove this concept.

Therefore, here we examined the potential of photoluminescent SNPs doped by {Mo6I8}4+ for applications such as bioimaging and photodynamic therapy using the human epidermoid larynx carcinoma (Hep-2) cell line as a model.

Our results demonstrated both: (i) significant luminescence from cells with internalised molybdenum cluster-doped SNPs combined with the low cytotoxicity of particles in the darkness and (ii) significant cytotoxicity of the particles upon photoirradiation. Thus, this research provides strong experimental evidence for high potential of molybdenum-cluster-doped materials in biomedical applications such as optical bioimaging, biolabeling and photodynamic therapy.
The influence of the finiteness of the proton radius and mass on the energies of a hydrogen atom and hydrogen-like ions in a superstrong magnetic field is studied. The finiteness of the nucleus size pushes the ground energy level up leading to a nontrivial dependence of the value of critical nucleus charge on the external magnetic field.
Presented paper is the next step in the research of axial transport in Gas Dynamic Trap. Experiments dedicated to the neutral gas role in the expander of mirror device were carried out.

Ion current density distribution measured at the end plate does not depend on neutral gas density in the expander. Experimental indications of neutral gas extrusion from the axis of the expander to its periphery were observed.

Numerical model describing such extrusion by elastic collisions of neutrals with plasma ions is in agreement with experimental data.
Two-phase Cryogenic Avalanche Detectors (CRADs) with combined THGEM/GAPD multiplier have become an emerging potential technique for dark matter search and coherent neutrino-nucleus scattering experiments. In such a multiplier the THGEM hole avalanches are optically recorded in the Near Infrared (NIR) using a matrix of Geiger-mode APDs (GAPDs).

To select the proper sensor, the performances of six GAPD types manufactured by different companies, namely by Hamamatsu (MPPCs), CPTA (MRS APDs) and SensL (SiPMs), have been comparatively studied at cryogenic temperatures when operated in two-phase CRADs in Ar at 87 K.

While the GAPDs with ceramic packages failed to operate properly at cryogenic temperatures, those with plastic packages, namely MPPC S10931-100P and MRS APD 149-35, showed satisfactory performances at 87 K. In addition, MPPC S10931-100P turned out to be superior in terms of the higher detection efficiency, lower nose rate, lower pixel quenching resistor and better characteristics reproducibility.
Microelectronics already needs for heat removal more than 1 kW/cm 2 . To assess the spray cooling capabilities to meet the growing requirements, a review of experimental studies is presented. Both the lack of progress in increasing the limit values of critical heat fluxes over the past 20-30 years and the fact that this technique is considered effective and promising are demonstrated. The “modern” physical picture has been formed at the turn of the 21st century. The review shows that the trend towards increasing the heat transfer coefficients is realized in the same way as in other promising cooling technologies. The paper refers to the studies in which the coolant film thickness was reduced by the authors, as well as those that presented correlations of the three-phase contact line dynamics with the values of the achieved heat flux. A problem is formulated for the required detailed studies of highly dynamic processes in an ultra-thin liquid film at the micro level, aimed at the heat transfer enhancement.
This paper analyzes problems revealed by practice of implementation of large-scale projects (megaprojects). It discusses features of large-scale projects, namely, their impact on the whole economy and high uncertainty regarding conditions of their implementation, as well as possibilities of the standard approach to assessing social efficiency of investment projects to adequately take account of these features.

Some ways to solve the problems under consideration are proposed.
The internal structure and construct (convergent and discriminant) validity of the Russian-language version of the Attitudes about reality (AAR) scale developed by R. K. Unger, R. D. Draper and R. D., & M. L. Pendergrass (1986) are examined.

The sample was 272 subjects. The confirmatory factor analysis revealed that both one-factor and three-factor structural models have poor fit indices. The exploratory factor analysis, in turn, did not allow to obtain an interpretable factor solution.

The study also showed that the internal consistency of AARS is rather low. The obtained correlations do not confirm the convergent validity of the scale, although they provide initial support for its discriminant validity. The results show that the AAR scale in its current form is not suitable for assessing individual's beliefs about reality.
The bubble growth process in a magmatic melt during decompression at a constant rate under various conditions is numerically studied.

The effect of the formation of a narrow boundary layer with a high viscosity around the bubble, which significantly changes the dynamics of the bubble, is taken into account.

It is shown that, at a low initial pressure in the medium, in the bubble high pressure is maintained throughout the calculation time. In the case of long decompression time, the final bubble radius is bigger than in the case with small decompression time. This effect can be associated with different dynamics of the medium viscosity in a narrow boundary layer around the bubble.
Results of calculations of high voltage electron cooling process in NICA collider are presented. Two independent electron cooling systems in the collider are intended to increase luminosity in space charge dominated regime. The model of cooling calculations was tested on experimental results, obtained in COSY synchrotron, which is equipped with 2 MeV electron cooler, produced by Budker INP. Also a project of high voltage electron cooling systems for the NICA collider is presented.
The paper discusses the results of measurement for three components of tensor analyzing power for the reaction of incoherent [Formula: see text]-meson photoproduction on a deuteron within the proton energy range of 15–200[Formula: see text]MeV and the neutron energy range of 15–150[Formula: see text]MeV.

The experiment was performed on the deuterium internal gas target of VEPP-3 electron accelerator using the protons and neutrons coincidence counting technique.

The results of measurements of the tensor analyzing power's components are compared with the results of statistical modeling performed within the frameworks of a theoretical model.
