The study of sorption and transport characteristics of a composite sorbent based on various types of glass microspheres is carried out.

In order to carry out this research, an experimental stand has been prepared for measuring sorbent characteristics at specified pressure and temperature values. The technique of carrying out the experiment and processing the experimental data for the purpose of determining the helium permeability of composite sorbents with a filler made of different material: sodium borosilicate glass, silica microspheres, cenospheres has been worked out.

The values of the helium permeability of the composite sorbent in the temperature range from 20 to 140 °C are determined. The transport characteristics of the medium formed by the granules of the composite sorbent, as well as the values of the characteristic time of helium sorption by the composite sorbent are found.

Results of a search for the pair production of photon-jets---collimated groupings of photons---in the ATLAS detector at the Large Hadron Collider are reported. Highly collimated photon-jets can arise from the decay of new, highly boosted particles that can decay to multiple photons collimated enough to be identified in the electromagnetic calorimeter as a single, photonlike energy cluster.

Data from proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of $36.7\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, were collected in 2015 and 2016. Candidate photon-jet pair production events are selected from those containing two reconstructed photons using a set of identification criteria much less stringent than that typically used for the selection of photons, with additional criteria applied to provide improved sensitivity to photon-jets. Narrow excesses in the reconstructed diphoton mass spectra are searched for.

The observed mass spectra are consistent with the Standard Model background expectation. The results are interpreted in the context of a model containing a new, high-mass scalar particle with narrow width, $X$, that decays into pairs of photon-jets via new, light particles, $a$. Upper limits are placed on the cross section times the product of branching ratios $\ensuremath{\sigma}\ifmmode\times\else\texttimes\fi{}\mathcal{B}(X\ensuremath{\rightarrow}aa)\ifmmode\times\else\texttimes\fi{}\mathcal{B}(a\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}{)}^{2}$ for $200\text{ }\text{ }\mathrm{GeV}<{m}_{X}<2\text{ }\text{ }\mathrm{TeV}$ and for ranges of ${m}_{a}$ from a lower mass of 100 MeV up to between 2 and 10 GeV, depending upon ${m}_{X}$. Upper limits are also placed on $\ensuremath{\sigma}\ifmmode\times\else\texttimes\fi{}\mathcal{B}(X\ensuremath{\rightarrow}aa)\ifmmode\times\else\texttimes\fi{}\mathcal{B}(a\ensuremath{\rightarrow}3{\ensuremath{\pi}}^{0}{)}^{2}$ for the same range of ${m}_{X}$ and for ranges of ${m}_{a}$ from a lower mass of 500 MeV up to between 2 and 10 GeV.

Pathogenesis of age-related macular degeneration (AMD), the leading cause of vision loss in the elderly, remains poorly understood due to the paucity of animal models that fully replicate the human disease. Recently, we showed that senescence-accelerated OXYS rats develop a retinopathy similar to human AMD.

To identify alterations in response to normal aging and progression of AMD-like retinopathy, we compared gene expression profiles of retina from 3- and 18-mo-old OXYS and control Wistar rats by means of high-throughput RNA sequencing (RNA-Seq). We identified 160 and 146 age-regulated genes in Wistar and OXYS retinas, respectively. The majority of them are related to the immune system and extracellular matrix turnover. Only 24 age-regulated genes were common for the two strains, suggestive of different rates and mechanisms of aging. Over 600 genes showed significant differences in expression between the two strains. These genes are involved in disease-associated pathways such as immune response, inflammation, apoptosis, Ca2+ homeostasis and oxidative stress. The altered expression for selected genes was confirmed by qRT-PCR analysis. To our knowledge, this study represents the first analysis of retinal transcriptome from young and old rats with biologic replicates generated by RNA-Seq technology.

We can conclude that the development of AMD-like retinopathy in OXYS rats is associated with an imbalance in immune and inflammatory responses. Aging alters the expression profile of numerous genes in the retina, and the genetic background of OXYS rats has a profound impact on the development of AMD-like retinopathy.
Genome evolution entails changes in the DNA sequence of genes and intergenic regions, changes in gene numbers, and also changes in gene order along the chromosomes. Genes are reshuffled by chromosomal rearrangements such as deletions/insertions, inversions, translocations, and transpositions. Here we report a comparative study of genome organization in the main African malaria vector, Anopheles gambiae , relative to the recently determined sequence of the Drosophila melanogaster genome. The ancestral lines of these two dipteran insects are thought to have separated ∼250 Myr, a long period that makes this genome comparison especially interesting. Sequence comparisons have identified 113 pairs of putative orthologs of the two species. Chromosomal mapping of orthologous genes reveals that each polytene chromosome arm has a homolog in the other species. Between 41% and 73% of the known orthologous genes remain linked in the respective homologous chromosomal arms, with the remainder translocated to various nonhomologous arms. Within homologous arms, gene order is extensively reshuffled, but a limited degree of conserved local synteny (microsynteny) can be recognized.
In laboratory experiments, purposeful predatory inter-relations with moving insects have been revealed and described in three species of herbivorous voles: the East European vole, the narrow-headed vole, and the Tuva silver vole.

The appearance of the full hunting stereotype in these species does not require preliminary experience, which indicates its innate nature.

The hunting behaviour of the Tuva silver vole differed from that of the East European vole and narrow-headed vole, which probably reflects the phylogenetic relationships between these species.
Chemotaxonomy as a system approach deals with intra- and interspecific polymorphism of a group of taxa in order to clarify their taxonomic positions or to select material for selection or introduction.

In this study we performed chemotaxonomic analysis of specimens of Miscanthus sinensis and M. sacchariflorus collected in the Russian Far East and of hybrid plants of both natural and artificial origin. We found 153 substances and identified 143 of them in extracts of eleven Miscanthus plants by gas chromatography-mass spectrometry (GC-MS). These substances can be grouped into alkanes (20 compounds), fatty acids (34), phenols (13), sterols (18) toсopherols (8), norterpenoids (12), and phytols (13), as well as their derivatives. The main components of the extracts of miscanthus samples are fatty acids and their derivatives (total content 19.94–41.02 %), dominated by palmitic and linolenic acids, and sterols (mainly β-sitosterol, stigmasterol, and α-amyrin), which constitute 17.15–31.73 %. The values of the CPI 'oddness index' for the alkane components of the extracts were within 1.55–7.18, with extracts from leaves of the Far Eastern samples characterized by the lower half of this range (1.55–2.74), while extracts from leaves of hybrids fell to the upper half (5.78–7.18). Principal component analysis of extraction profiles allowed us to separate three distinct clusters: M. sinensis , M. sachariflorus , and their hybrids, as well as to verify the origin of one of the natural hybrids.

The results of chemotaxonomic analysis mostly matched those of DNA sequencing of a fragment of the plastid genome, which, moreover, allowed us to identify the species nature of the maternal plants used to obtain these hybrids. Chemotaxonomic analysis using GC-MS was found to be an efficient additional technique to delimit various morphological forms of M. sinensis , M. sachariflorus , and their hybrids.
In order to speed up the calculation of tsunami wave propagation, the field-programmable gate array (FPGA) microchip is used. This makes it possible to achieve valuable performance gain with a modern regular personal computer. The two half-step MacCormack scheme was used herein for numerical approximation of the shallow water system. We studied the distribution of tsunami wave maximal heights along the coast of the southern part of Japan. In particular, the dependence of wave maximal heights on the particular tsunami source location was investigated. Synthetic 100 × 200 km sources have realistic parameters corresponding to this region. As observed numerically, only selected parts of the entire coast line are subject to dangerous tsunami wave amplitudes. The particular locations of such areas strongly depend on the location of the tsunami source. However, the extreme tsunami heights in some of those areas can be attributed to local bathymetry. The proposed hardware acceleration to compute tsunami wave propagation can be used for rapid (say, in a few minutes) tsunami wave danger evaluation for a particular village or industrial unit on the coast.
This is a defense of Pyrrhonian skepticism against the charge that the suspension of judgment based on equipollence is vitiated by the assent given to the equipollence in question. The apparent conflict has a conceptual side as well as a practical side, examined here as separate challenges with a section devoted to each. The conceptual challenge is that the skeptical transition from an equipollence of arguments to a suspension of judgment is undermined either by a logical contradiction or by an epistemic inconsistency, perhaps by both, because the determination and affirmation of equipollence is itself a judgment of sorts, one that is not suspended. The practical challenge is that, independently of any conceptual confusion or contradiction, suspending judgment in reaction to equipollence evinces doxastic commitment to equipollence, if only because human beings are not capable of making assessments requiring rational determination without believing the corresponding premises and conclusions to be true. The two analytic sections addressing these challenges are preceded by two prefatory sections, one laying out the epistemic process, the other reviewing the evidentiary context. The response from the conceptual perspective is that the suspension of judgment based on equipollence is not a reasoned conclusion adopted as the truth of the matter but a natural reaction to an impression left by the apparently equal weight of opposing arguments. The response from the practical perspective is that the acknowledgment of equipollence is not just an affirmation of the equal weight of arguments but also an admission of inability to decide, suggesting that any assent, express or implied, is thrust upon the Pyrrhonist in a state of epistemic paralysis affecting the will and the intellect on the matter being investigated. This just leaves a deep disagreement, if any, regarding whether equipollence is an inference based on discursive activity or an impression coming from passive receptivity. But this, even if resolved in favor of the critic (which it need not and ought not be), is not the same as confusion or inconsistency on the part of the Pyrrhonist, the demonstration of which is the primary aim of this paper
This article is devoted to the study of pressure pulsations behind the runner of a hydro turbine model caused by the precessing vortex core (PVC). Pressure pulsations are investigated under conditions of stationary load and transient modes of the hydro-turbine operation. Studies were performed in model conditions on the aerodynamic setup. The map of pressure pulsations was built for stationary modes using acoustic sensors and served to find rotational speeds of the swirler and flow rates at which the PVC occurs. On the basis of the data presented by parametric dependences, the initial and final parameters of the transition process were chosen. In the article, a sudden (fast) transition from part-load regime to the best efficiency point and back was considered. The characteristic times for the formation of PVC and the establishment of the flow regime when changing the controlling parameters of the installation have been determined using a continuous wavelet transform.

Numerical simulation of supersonic flow past a cylinder with a frontal gas-permeable insert is performed using the skeleton model of a highly porous cellular material.

Numerical simulation was carried out within the framework of two-dimensional RANS equations written in an axisymmetric form. The skeleton model is a system of coaxial rings of different diameters, arranged in staggered order. The calculations were carried out in a wide range of determining parameters: Mach numbers M∞ = 3, 4.85 and 7, unit Reynolds numbers Re1∞ = 13.8×105 ÷ 13.8×106 m-1, the cylinder diameter 6÷40mm, the length of the porous insert 3÷45mm, the cell diameter of 1 and 3 mm.

The results of the calculations are consistent with the available experimental data. The applicability of the skeleton model for the description of supersonic flow around axisymmetric bodies with front inserts from cellular-porous materials is shown.
In recent years, using a genome-wide association study (GWAS), a number of single nucleotide polymorphisms (SNPs) have been suggested to be associated with susceptibility to leukemia in cattle. However, all studies have been done with purebred Holstein cows and their hybrids. In this regard, it is important to confirm the functional role of polymorphisms previously identified in a GWAS study in Russian cattle breeds. The aim of this study was to verify the association between rs110861313 in the intergenic region of bovine chromosome 23 and leukemia in the Russian Black Pied cattle. Based on the levels of bovine leukemia virus (BLV)-specific antibodies detected in serum using serodiagnostic techniques, animals were divided into three groups: healthy animals ( n = 115), asymptomatic virus carriers ( n = 145) and animals with leukemia ( n = 107). Genotyping of rs110861313 was carried out using polymerase chain reaction followed by analysis of restriction fragment length polymorphisms. A significant decrease in the frequency of the A/A genotype (11.2 %) was revealed in animals with persistent lymphocytosis compared to virus carriers (27.6 %) ( p < 0.002). At the same time, the frequency of animals with the C/C genotype in animals with persistent lymphocytosis (41.1 %) was significantly higher than that of virus carriers (21.4 %) ( p < 0.001). In this case, asymptomatic virus carriers can be considered a more suitable control than healthy animals that have not been in contact with the virus. According to bioinformatics analysis, resistance to BLV can be due to the presence of the transcription factor FOXM1 binding site in the region of rs110861313. FOXM1 is expressed in immune cells and can potentially affect the expression of the neighboring genes ( LY6G5B, GPANK1, ABHD16A, LY6G6F, LY6G6E, CSNK2B, ApoM ). Thus, we found that SNP rs110861313 in the intergenic region of bovine chromosome 23 is associated with the development of leukemia following BLV infection in the Russian Black Pied cattle.
Die Kernspinresonanz (NMR) hat sich zu einer universellen Methode für biochemische und biomedizinische Studien, einschließlich Metabolomik, Proteomik und Magnetresonanztomographie (MRT), entwickelt. Durch die Vervielfachung des NMR‐Signals ausgewählter Moleküle hat die Kernspin‐Hyperpolarisation das Anwendungsspektrum von NMR und MRT bedeutsam erweitert (z. B. hyperpolarisierte Festkörper‐NMR und metabolische Bildgebung in vivo). Parawasserstoff (pH 2 ) erlaubt es, Moleküle schnell und kostengünstig zu hyperpolarisieren. In diesem Gebiet wurden in den letzten zehn Jahren umfangreiche Fortschritte erzielt, einschließlich der Synthese neuer Tracer, Katalysatoren und Methoden für die Polarisationsübertragung. Das Portfolio an hyperpolarisierten Molekülen umfasst nunmehr Aminosäuren, die für viele Anwendungen von großem Interesse sind. In diesem Beitrag beleuchten wir die aktuelle Literatur zur Hyperpolarisation von Aminosäuren und Peptiden.
This article is devoted to the development of the direct resistive heating of oxygen transport membranes technique.

In this case, DC was selected to perform direct heating. The effect of DC on the oxygen fluxes and the microstructure of the membrane was studied.

It is shown that in the short-term experiment with DC, a positive significant effect on the oxygen transport was found, while sample exposure under the influence of DC for a long period of time had a significant negative effect on the microstructure of the membrane.
Details of the calculation of the non-forward BFKL kernel at next-to-leading order (NLO) are offered. Specifically we show the calculation of the two-gluon production contribution. This contribution was the last missing part of the kernel. Together with the NLO gluon Regge trajectory, the NLO contribution of one-gluon production and the contribution of quark-antiquark production which were found before it defines the kernel completely for any colour state in the $t$-channel, in particular the Pomeron kernel presented recently.
The effect of sonication time during the synthesis of multiwalled carbon nanotubes -polymethylmethacrylate (MWCNT/PMMA) composites by coagulation technique on the MWCNT distribution in the bulk of the composites close to the percolation threshold was systematically studied by SEM and by measurements on specific resistivity in a wide range of voltages and external pressure.It was found that the resistivity of composites is irreversibly reduced up to 10 5 times during the first 1-3 measurements, while further measurements are characterized by high repeatability.Change of the composite resistivity during the measurements is discussed assuming that several types of contacts between the nanotubes changing during the measurement are present.It was found that an increase of the sonication time changed the ratio between ohmic and non-ohmic contacts.It affected the type of changes in the sample resistivity during the voltage variation in the range of 0-10 3 V/mm and resulted in a nonuniform dependence of the composite specific resistivity on the sonication time.An increase of the composite volume during the resistivity measurements was observed at the current densities above 4•10 -8 A/cm 2 .New ohmic contacts were found to form when external pressure was applied due to squeezing of the polymer matrix from the space between adjacent nanotubes.
In this work we consider Malcev bialgebras. We describe all structures of a Malcev bialgebra on a simple non-Lie Malcev algebra.
The theoretical analysis of basic phenomena at plasma processing of the agglomerated powders, in context of hollow microspherical particles production, was fulfilled. With the use of the obtained theoretical solutions for the first time the key similarity criteria were derived that allow to formulate the requirements to plasma flow, characteristics of agglomerate and its material as well as condition of quenching of the formed hollow microdroplet which realization provides the formation of hollow microsphere with necessary characteristics, in particular, of maximal diameter and minimum thickness of shell.
PARP-1 synthesizes long poly(ADP-ribose) chains (PAR) at DNA damage sites to recruit DNA repair factors. Among proteins relocated on damaged DNA, the RNA-binding protein FUS is one of the most abundant, raising the issue about its involvement in DNA repair.

Here, we reconstituted the PARP-1/PAR/DNA system in vitro and analyzed at the single-molecule level the role of FUS. We demonstrate successively the dissociation of FUS from mRNA, its recruitment at DNA damage sites through its binding to PAR, and the assembly of damaged DNA-rich compartments. PARG, an enzyme family that hydrolyzes PAR, is sufficient to dissociate damaged DNA-rich compartments in vitro and initiates the nucleocytoplasmic shuttling of FUS in cells.

We anticipate that, consistent with previous models, FUS facilitates DNA repair through the transient compartmentalization of DNA damage sites. The nucleocytoplasmic shuttling of FUS after the PARG-mediated compartment dissociation may participate in the formation of cytoplasmic FUS aggregates.
A quantized optical cavity mode controlled by dissipation, squeezed-light source and feedback loop is studied. The feedback is activated by detections of photons leaving the cavity and rapidly shifts the phase of the cavity field by π. The steady-state of the mode and first-order field correlation functions are obtained in closed analytical form and investigated. It appears that the feedback radically modifies the mode's spectrum. It gains asymmetry and its double-peaked structure becomes much more pronounced than in no-feedback case.
We calculate in the next-to-leading approximation the nonforward quark impact factors for both singlet and octet color representations in the t channel.

The integral representation of the octet impact factor in the general case of arbitrary space-time dimension and massive quark flavors is used to check the so-called ``second bootstrap condition'' for gluon Reggeization at the next-to-leading logarithmic approximation in perturbative QCD.

We find that it is satisfied for both helicity conserving and nonconserving parts. The integrations are then performed for the explicit calculation of the impact factors in the massless quark case.
Wind as a natural phenomenon as well as the peculiarities of specific winds, such as Boreas, Notos, Eurus, and Zephyrus and their influences on navigation, agriculture and, in general, human live are among the subjects, extensively treated by the Peripatetics. Winds are studied in Aristotle’s Meteorology (1.13, 2.4 sq.), Book 26 of the Problems, the Peripatetic On signs and On the position and Names of the Wind, in an epitome of a meteorological work, ascribed to Theophrastus (the so-called Metarsiology, preserved only in Arabic and Syriac translations) and, finally, in his short (and incomplete) treatise On Winds.

The latter work is of special interest not only because it is the only Peripatetic treatise especially dedicated to winds; as such it is a valuable witness of Theophrastus’ position on the nature of this natural phenomenon, generally different from the one advanced by Aristotle.

Having summarized some aspects of this rather neglected treatise, I try to correlate meteorological information and explanations offered by Theophrastus with contemporary data, especially in the context of the history of navigation.
