Ni-substituted Sr-aluminates Sr 1-x Ni x Al 11.2+x Ni 0.8-x O 19-δ (x = 0; 0.2; 0.4; 0.8) obtained by a precipitation method and calcined at 1200°C have been characterized by different physicochemical techniques and their catalytic properties have been tested in steam reformation of methane.It has been shown that substitution of Al 3+ and/or Sr 2+ by Ni 2+ in the aluminate structure results in changes of phase composition, specific surface area, and reducibility of samples.It has been established that the samples are not completely reduced in the temperature range of 30-900°C.The Sr 1-x Ni x Al 11.2+x Ni 0.8-x O 19-δ (x = 0; 0.2; 0.4) catalysts are active and stable in the steam reforming of methane at 700oC: residual amount of methane is (1.1±1.0)vol.%, while the Sr 1-x Ni x Al 11.2+x Ni 0.8-x O 19-δ (x = 0.8) sample is rapidly deactivated by coking.
We predict the onset of self-induced parametric or Faraday instabilities in a laser, spontaneously caused by the presence of pump depletion, which leads to a periodic gain landscape for light propagating in the cavity. As a result of the instability, continuous wave oscillation becomes unstable even in the normal dispersion regime of the cavity, and a periodic train of pulses with ultrahigh repetition rate is generated. Application to the case of Raman fiber lasers is described, in good quantitative agreement between our conceptual analysis and numerical modeling.
We deduce the formula of the asymptotics of the spectrum of the linear problem on the stability of stationary flows of an incompressible polymeric fluid with volume charge.
While the mathematical modeling of optical phenomena, a computer calculation is often performed, confirming the conclusions made.To do this, a virtual computer model of the optical installation is created in the form of a 3D scene.Also, virtual scenes are often used in training when creating presentations.

This paper describes computer models of spherical lenses and the calculation of interaction of linear polarized light rays with them.It is focused on applications that use ray tracing.The reflected and all rays passing through the lens that arise due to internal reflections are calculated from the ray incident on the scene object.The number of internal reflections is set by the parameter.All output rays are calculated based on the application of Fresnel's equations and are characterized by intensity values and polarization parameters.They are constructed on the basis of the application of the set-theoretic intersection of geometric primitives: a half-space, a sphere, a cone, a cylinder and their complements to the scene space.An advanced user can build their own objects by analogy, for example, cylindrical lenses.

It is known that light of any polarization can be represented on the basis of the mentioned one.We selected spherical lenses since they are most often used in optic installations.
A search for the direct production of the supersymmetric partners of $\tau$-leptons (staus) in final states with two hadronically decaying $\tau$-leptons is presented. The analysis uses a dataset of $pp$ collisions corresponding to an integrated luminosity of $139$ fb$^{-1}$, recorded with the ATLAS detector at the Large Hadron Collider at a center-of-mass energy of 13 TeV. No significant deviation from the expected Standard Model background is observed. Limits are derived in scenarios of direct production of stau pairs with each stau decaying into the stable lightest neutralino and one $\tau$-lepton in simplified models where the two stau mass eigenstates are degenerate. Stau masses from 120 GeV to 390 GeV are excluded at 95% confidence level for a massless lightest neutralino.
An amorphous solid dispersion (SD) of curcumin (Cur) with disodium glycyrrhizin (Na2GA) was prepared by mechanical ball milling. Curcumin loaded micelles were self-formed by Na2GA when SD dissolved in water. The physical properties of Cur SD in solid state were characterized by differential scanning calorimetry, X-ray diffraction studies, and scanning electron microscope. The characteristics of the sample solutions were analyzed by reverse phase HPLC, UV-visible spectroscopy, 1H NMR spectroscopy, gel permeation LC, and transmission electron microscopy. In vitro cytotoxic tests demonstrated that Cur SD induced higher cytotoxicity against glioblastoma U-87 MG cells than free Cur. Besides, an improvement of membrane permeability of Cur SD was confirmed by parallel artificial membrane permeability assay. Further pharmacokinetic study of this SD formulation in rat showed a significant ∼19-fold increase of bioavailability as comparing to free Cur. Thus, Cur SD provide a more potent and efficacious formulation for Cur oral delivery.
Eukaryotic genomes encode thousands of non-coding RNAs (ncRNAs), which play crucial roles in transcriptional and post-transcriptional regulation of gene expression. Accumulating evidence indicates that ncRNAs, especially microRNAs (miRNAs) and long ncRNAs (lncRNAs), have emerged as key regulatory molecules in plant stress responses. In this review, we have summarized the current progress on the understanding of plant miRNA and lncRNA identification, characteristics, bioinformatics tools, and resources, and provided examples of mechanisms of miRNA- and lncRNA-mediated plant stress tolerance.
Gold atoms dispersed on multiwalled carbon nanotubes have been successfully utilized in the heterogeneous hydrogenation of 1,3-butadiene or 1-butyne with parahydrogen

as reported by K. V. Kovtunov et al. in their Communication on page 7012 ff

The estimated contributions of the pairwise hydrogen addition route, and therefore the achieved NMR signal enhancement levels, are at least an order of magnitude higher than those obtained with supported metal nanoparticles
Wolbachia are maternally inherited symbiotic bacteria that are widespread among arthropods and filarial nematode parasites. It has been found in all main insect orders although some of them are still insufficiently studied.

We performed PCR-screening for 15 species, 252 samples of fleas (Siphonaptera), that had been collected in the Sverdlovsk region and Khabarovsk territory.

Six new symbiotic associations of Wolbachia-Siphonaptera were found for the first time. On the basis of earlier published data and the results of the current study we estimate that a minimum of 500 out of 2000 species in the Siphonaptera order are infected with Wolbachia
Currently, cucurbiturils are being actively researched all over the world. Research is focused on the ways of improving the solubility and selectivity of cucurbiturils, increasing the stability of the complexes with other particles in various media and enhancing their ability to bind and release various substances.

The most significant area of our research is the assessment of safety, studying the biological properties and synergistic effects of cucurbiturils during complexation with drugs. In this article, the hemocompatibility of erythrocytes and leukocytes with cucurbiturils was investigated.

We demonstrated that cucurbiturils have no cytotoxic effect, even at high concentrations (1 mM) and do not affect the viability of PBMCs. However, cucurbiturils can increase the level of the early apoptosis of lymphocytes and cucurbit[7]uril enhances hemolysis in biologically relevant media. Despite this, cucurbiturils are fairly safe organic molecules in concentrations up to 0.3 mM. Thus, we believe that it will become possible to use polymer nanostructures as drug delivery systems in clinical practice, since cucurbiturils can be modified to improve pharmacological properties.
The h-index is an important bibliographic measure used to assess the performance of researchers. Dutiful researchers merge different versions of their articles in their Google Scholar profile even though this can decrease their h-index. In this article, we study the manipulation of the h-index by undoing such merges. In contrast to manipulation by merging articles (van Bevern et al. [Artif. Intel. 240:19-35, 2016]) such manipulation is harder to detect. We present numerous results on computational complexity (from linear-time algorithms to parameterized computational hardness results) and empirically indicate that at least small improvements of the h-index by splitting merged articles are unfortunately easily achievable.
This article reflects the results of studying the infographics on the sites of large cities in Siberia – the second stage of infographics studying in regional media, specifically of the most cited Internet mass media of Krasnoyarsk and Omsk cities with a population of over 1 million people in the Siberian Federal District. During the first stage it was shown how this format was developed chronologically and how many infographics were published on these sites over the years. At the second stage of the study, the content analysis method and the typological method were applied to the generated empirical database, and the audience indicators of the respective projects were analyzed. As a result, the article provides quantitative characteristics of different types of infographics. The typology was carried out for various reasons: autonomy from the accompanying text, interactivity, type of presentation of data (processes, objects), which corresponds to the created information graphics. The text also describes the various editorial features of creating infographics in seven analyzed online media, answers to questions: do the editors create their own infographics or borrow it for information or advertising purposes, which topics are visualized in this way, what data sources are used, in which programs do they work and etc. And the analysis of audience indicators allows us to conclude whether the presence of infographics in the text helps to increase the number of readings.
Comparative studies showed that DMM OSR exceeded DMM steam reforming (SR) and DMM partial oxidation (PO) in terms of hydrogen productivity.

The catalytic properties of CuO-CeO2 supported on alumina for the oxidative steam reforming (OSR) of dimethoxymethane (DMM) to hydrogen-rich gas in a tubular fixed bed reactor were studied. The CuO-CeO2/γ-Al2O3 catalyst provided complete DMM conversion and hydrogen productivity > 10 L h−1 gcat−1 at 280 °C, GHSV (gas hourly space velocity) = 15,000 h−1 and DMM:O2:H2O:N2 = 10:2.5:40:47.5 vol.%.

Thus, the outcomes of lab-scale catalytic experiments show high promise of DMM oxidative steam reforming to produce hydrogen-rich gas for fuel cell feeding.
The purpose of the research is to evaluate the effect of albendazole as part of the supramolecular complex with disodium salt of glycyrrhizic acid obtained by solid-phase mechanical treatment. Materials and methods. The anthelmintic activity of the complex and its effect on the host organism was assessed on hamsters infected with Opisthorchis felineus by single and 7-fold administration at 45 days after infection. After 21 days, we counted the number of helminthes in the liver, and conducted a morphometric analysis of the liver and spleen, and detected biochemically the activity of alanine aminotransferase and aspartate aminotransferase in the animals’ blood serum. Results and discussion. The number of O. felineus significantly decreased after 7-fold, but not a single, administration of albendazole (ABZ) and ABZ-Na 2 GA complex (1 : 10). The administrated substances had no effect on the weight gain of the animals and the daily consumption of the pellets. At the same time, ABZ only as part of the complex normalized the weight of the liver and spleen in hamsters infected with O. felineus and reduced the alanine aminotransferase activity. Consequently, a longer administration of ABZ as part of the complex with disodium glycyrrhizinate has not only a pronounced anthelmintic effect, but also improves some of the physiological parameters of hamsters to a greater extent than a pure substance.
An increase in the prevalence of autosomal recessive deafness 1A (DFNB1A) in populations of European descent was shown to be promoted by assortative marriages among deaf people. Assortative marriages became possible with the widespread introduction of sign language, resulting in increased genetic fitness of deaf individuals and, thereby, relaxing selection against deafness. However, the effect of this phenomenon was not previously studied in populations with different genetic structures.

We developed an agent-based computer model for the analysis of the spread of DFNB1A. Using this model, we tested the impact of different intensities of selection pressure against deafness in an isolated human population over 400 years.

Modeling of the 'purifying' selection pressure on deafness ('No deaf mating' scenario) resulted in a decrease in the proportion of deaf individuals and the pathogenic allele frequency. Modeling of the 'relaxed' selection ('Assortative mating' scenario) resulted in an increase in the proportion of deaf individuals in the first four generations, which then quickly plateaued with a subsequent decline and a decrease in the pathogenic allele frequency. The results of neutral selection pressure modeling ('Random mating' scenario) showed no significant changes in the proportion of deaf individuals or the pathogenic allele frequency after 400 years.
Five new cluster compounds based on [Mo6Bri8(CN)a6]2−and [Mo6Bri6Qi2(CN)a6]n−(Q = S, Se,n= 3, 4) cluster units have been synthesized and characterized.
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.
Influenza A virus (IAV) causes a respiratory infection that affects millions of people of different age groups and can lead to acute respiratory distress syndrome. Currently, host genes, receptors, and other cellular components critical for IAV replication are actively studied.

One of the most convenient and accessible genome-editing tools to facilitate these studies is the CRISPR/Cas9 system. This tool allows for regulating the expression of both viral and host cell genes to enhance or impair viral entry and replication.

This review considers the effect of the genome editing system on specific target genes in cells (human and chicken) in terms of subsequent changes in the influenza virus life cycle and the efficiency of virus particle production.
The front cover displays novel ionic liquid crystalline (ILC) compounds containing a nitroxide radical unit in the organic cations, showing an enantiotropic smectic A (SmA) phase. One of the ILC compounds shows strong intermolecular magnetic interactions owing to the nanosegregation of strongly bonded ionic and non-ionic moieties. Its droplet can be magnetically manipulable. More information can be found in the Full Paper by Yoshiaki Uchida, Rui Tamura, and co-workers.
We study the plasma-vacuum interface problem in relativistic magnetohydrodynamics for the case when the plasma density does not go to zero continuously, but jumps. In the vacuum region we consider the Maxwell equations for electric and magnetic fields. We show that a sufficiently large vacuum electric field can make the planar interface violently unstable. By using a suitable secondary symmetrization of the vacuum Maxwell equations, we find a sufficient condition that precludes violent instabilities. Under this condition we derive an energy a priori estimate in the anisotropic weighted Sobolev space $H^1_*$ for the variable coefficients linearized problem for nonplanar plasma-vacuum interfaces.
The authors investigate the historical fate of one of four construction mega-projects of Qin Shihuangdi, namely, Epang Palace which was supposed to become the worthy dwelling for the first unifier of the Celestial Empire. Construction workers erected the giant platform-stylobate and built three walls around it. During the Middle Ages (from the end of the Han dynasty and up to the Tang dynasty) it accommodated the military Echeng settlement. Within the same period of time, by the efforts of literati and, first of all, by prominent poet Du Mu (803–852) who wrote “The Ode on Epang Palace”, a myth was created about the wonderful residence of the Emperor with many features such as watchtowers, pavilions and galleries, and how all these beauties were destroyed by rebellions in the great fire. Nevertheless, regular archaeological excavations conducted at the site during the period of 2002–2004 did not reveal any traces of such a fire. The Palace wasn’t burned down – it was simply never constructed. Furthermore, though the huge base platform of the Palace was registered by UNESCO experts as the biggest palace building in the world, no further complicated constructions were found on its surface (though some evidence of preparatory works were reported, for example, the many pieces of roofing tiles that were lifted to the platform). The results of archaeological investigations of real Epang meant the death-warrant to false Epang that was built by local authorities as popular tourist attraction, means a source of money. It was ruined in 2012 and replaced with archaeological park where all construction works were to be based on scientific reconstruction.
interrelation oF traCe eleMents and tHe strUCtUral orGaniZation oF lYMPH nodes at YoUnG and senile aGe A B S T R A C T -The article deals with the study of interrelation of trace elements and morphology of lymph nodes at different localization and age-related changes.Lymph nodes of different localization at young and old animals were analyzed by a morphological method with definition of trace elements by roentgen fluorescent method and the use of synchrotron radiation.There are data on forming of the lymphoid-microelement association important for integrative assessment of the structural organization of lymph nodes.Structural modification of lymph nodes has certain patterns, proceeding from features of a microelement profile.The region-dependent morphological variant of lymph nodes corresponds to a certain content of trace elements and their correlation with compartments of lymph nodes.Trace elements deficiency and reduction of compartments of lymph nodes are considered as predictors of aging of lymphoid tissue.The results have practical significance to justify a higher traceelement content in anti-aging programs.
The Gaching high-sulfidation (HS) epithermal Au–Ag deposits, part of the Maletoyvayam ore field, which is located in the volcanic belts of the Kamchatka Peninsula (Russia). The main ore components are native gold, tellurides, selenides, and sulphoselenotellurides of Au and oxidation products of Au-tellurides.

This study examines the different types of native gold in this ore deposit and the mechanisms and sequential transformation of calaverite (AuTe2) into mustard gold.

The primary high fineness gold (964‰–978‰) intergrown with maletoyvayamite Au3Te6Se4 and other unnamed phases (AuSe, Au(Te,Se)) differ from the secondary (mustard) gold in terms of fineness (1000‰) and texture. Primary gold is homogeneous, whereas mustard is spongy. Two types of mustard gold were identified: (a) Mixtures of Fe-Sb(Te,Se,S) oxides and fine gold particles, which formed during the hypogenic transformation stage of calaverite due to the impact of hydrothermal fluids, and (b) spotted and colloform gold consisting of aggregates of gold particles in a goethite/hydrogoethite matrix. This formed during the hypergenic transformation stage. Selenides and sulphoselenotellurides of gold did not undergo oxidation. Pseudomorphic replacement of calaverite by Au-Sb(Te,Se,S,As) oxides was also observed.
Type 2 diabetes (T2D) is a metabolic disorder characterized by disturbances of carbohydrate, fat and protein metabolism and insulin resistance. The majority of T2D patients are obese and obesity by itself may be a cause of insulin resistance.

Our aim was to evaluate whether the recently identified T2D risk alleles are associated with human measures of fatness as characterized with Dual Energy X-ray Absorptiometry (DEXA).Genotypes and phenotypes of approximately 3,000 participants from cross-sectional ERF study were analyzed. Nine single nucleotide polymorphisms (SNPs) in CDKN2AB, CDKAL1, FTO, HHEX, IGF2BP2, KCNJ11, PPARG, SLC30A8 and TCF7L2 were genotyped. We used linear regression to study association between individual SNPs and the combined allelic risk score with body mass index (BMI), fat mass index (FMI), fat percentage (FAT), waist circumference (WC) and waist to hip ratio (WHR).

Significant association was observed between rs8050136 (FTO) and BMI (p = 0.003), FMI (p = 0.007) and WC (p = 0.03); fat percentage was borderline significant (p = 0.053). No other SNPs alone or combined in a risk score demonstrated significant association to the measures of fatness.From the recently identified T2D risk variants only the risk variant of the FTO gene (rs8050136) showed statistically significant association with BMI, FMI, and WC.
Two types of the karyomorphs in the katydid Mecopoda elongata (L.) from Borneo (Malaysia) and Amami Is. (Japan) were found. The chromosomal complement of M. elongata from Amami Is. and one karyomorph from Borneo (Kota Kinabalu – song 1) consists of 28 autosomes plus the X in the male (2n = 29). In two long pairs, pair L1 is metacentric, whereas pair L2 is subacrocentric. Other autosomes are meta or submetacentric. The size and shape of the X chromosome is similar to the L1 pair. “Kota Kinabalu - song-2” karyomorph has the same chromosome number as “KK song-1” and “Amami”. However, in “KK song-2” the autosomes belonging to L2 pair are metacentric. The size of these chromosomes is approximately similar to the L1 pair and the X chromosome. The discrete chromosome differentiation in M. elongata suggest that this species consists of several biological species. In M. elongata from Borneo, the assumption of a belonging of two groups of the karyomorphs to different species proves to be true also in differences in crepitating.

Several mutations were introduced into the putative serine protease domain of the tick-borne encephalitis virus NS3 protein and into a possible internal cleavage site within the protein.

The influence of these mutations on proteolytic activity of NS3 protein and NS3' protein formation was tested in vitro. Mutations affecting the Ser-138 residue of the NS3 protein prohibited cleavage between NS2B and NS3 proteins when the NS2B-NS3 part of the viral genome was expressed in vitro.

It was found that NS3' formation was not dependent on the activity of the NS3 N-terminal serine protease, suggesting the key role of Ser-138 in viral serine protease functioning.
