The complex [Zn2(tdc)2dabco] (H2tdc = thiophene-2,5-dicarboxylic acid; dabco = 1,4-diazabicyclooctane) shows a remarkable increase in carbon dioxide (CO2) uptake and CO2/dinitrogen (N2) selectivity compared to the nonthiophene analogue [Zn2(bdc)2dabco] (H2bdc = benzene-1,4-dicarboxylic acid; terephthalic acid).

CO2 adsorption at 1 bar for [Zn2(tdc)2dabco] is 67.4 cm3·g–1 (13.2 wt %) at 298 K and 153 cm3·g–1 (30.0 wt %) at 273 K. For [Zn2(bdc)2dabco], the equivalent values are 46 cm3·g–1 (9.0 wt %) and 122 cm3·g–1 (23.9 wt %), respectively. The isosteric heat of adsorption for CO2 in [Zn2(tdc)2dabco] at zero coverage is low (23.65 kJ·mol–1), ensuring facile regeneration of the porous material. Enhancement by the thiophene group on the separation of CO2/N2 gas mixtures has been confirmed by both ideal adsorbate solution theory calculations and dynamic breakthrough experiments. The preferred binding sites of adsorbed CO2 in [Zn2(tdc)2dabco] have been unambiguously determined by in situ single-crystal diffraction studies on CO2-loaded [Zn2(tdc)2dabco], coupled with quantum-chemical calculations.

These studies unveil the role of the thiophene moieties in the specific CO2 binding via an induced dipole interaction between CO2 and the sulfur center, confirming that an enhanced CO2 capacity in [Zn2(tdc)2dabco] is achieved without the presence of open metal sites. The experimental data and theoretical insight suggest a viable strategy for improvement of the adsorption properties of already known materials through the incorporation of sulfur-based heterocycles within their porous structures.
Using the data-compression method we revealed a similarity between hunting behaviors of the common shrew, which is insectivorous, and several rodent species with different types of diet. Seven rodent species studied displayed succinct, highly predictable hunting stereotypes, in which it was easy for the data compressor to find regularities. The generalist Norway rat, with its changeable manipulation of prey and less predictable transitions between stereotype elements, significantly differs from other species. The levels of complexities of hunting stereotypes in young and adult rats are similar, and both groups had no prior experience with the prey, so one can assume that it is not learning, but rather the specificity of the organization of the stereotype that is responsible for the nature of the hunting behavior in rats. We speculate that rodents possess different types of hunting behaviors, one of which is based on a succinct insectivorous standard, and another type, perhaps characteristic of generalists, which is less ordered and is characterized by poorly predictable transitions between elements. We suggest that the data-compression method may well be more broadly applicable to behavioral analysis.
We consider the six dimensional N=(1,0) hypermultiplet model coupled to an external field of the Abelian vector multiplet in harmonic superspace approach.

Using the superfield proper-time technique we find the divergent part of the effective action and derive the complete finite induced low-energy superfield effective action.

This effective action depends on external field and contains in bosonic sector all the powers of the constant Maxwell field strength. The obtained result can be treated as the 6D, N=(1,0) supersymmetric Heisenberg-Euler type effective action.
Purpose. The article discusses the development of Middle Paleolithic assemblages in Caucasus during MIS5. The majority of Middle Paleolithic Caucasus archaeological sites are located in Southern Caucasus and along the Black Sea coast. In Northeastern Caucasus only a few exposed lithic assemblages were reported that demonstrate technical and typological characteristics typical for the Middle Paleolithic. During the last decade more than 20 Paleolithic sites including several multilayered occupations in the Darvagchai and Rubas River basins have been discovered. The assemblages from Coastal Dagestan sites like Rubas-1 (layer 3), Darvagchai-zaliv-1 (complex 2), Chumus-Inic, Rubas-2–5 etc. should be associated with the Middle Paleolithic. Cultural bearing layers of the majority of the sites had been included in the pebble glomeration, dated to Late Khazar time (0,2–0,1 Ma). The total number of artifacts in these assemblages is ~ 1700 items. Most of them (~ 1400 items) were found in the stratified sediments (Rubas-1 (layer 3), Darvagchai-zaliv-1 (complex 2), etc.). Results. The techniques of parallel unifacial, radial and Levallois flaking are typical for the Middle Paleolithic complexes of Coastal Dagestan. Generally, these assemblages can be characterized as non-Levallois and non-laminar (Ilam ~ 10), with the limited presence of Levallois technique and low faceting indices (IL and IF < 20). However, Levallois technique produced both elongated blanks, including points, and flakes. Narrow-faced cores were rarely used. Flakes were used as tool-blanks. Such tools as side-scrapers, denticulate, notched tools and perforators dominate in the tool kits. Levallois and Mousterian points were rare. There are many rough end-scrapers and knifes found, but Upper Paleolithic types of tools, such as burins, borers, etc., are sporadic. Limaces were rare. Truncated-faceted tools with base rejuvenation and bifaces typical for different Caucasus Middle Paleolithic assemblages have not been identified. Coastal Dagestan Middle Paleolithic sites demonstrate significant differences with synchronous Caucasus assemblages (Kudaro I Cave (layers 4–3), Kudaro III Cave (layers 4–3), Cona Cave (layer 5) in South Ossetia; Djurchula Cave, Copi I Cave in Georgia; Myshtulagty-lagat Cave (layers 14–12) in North Ossetia; Erevanskaya Cave (layers 7–5А), Hovk-I Cave (layers 12–8) in Armenia; Azih Cave (layer III) in Azerbaijan). Conclusion. Comparison of Coastal Dagestan sites with other Caucasus Middle Paleolithic sites has revealed significant differences between them. However, during the early stages of occupations, Dagestan Middle Paleolithic sites share some similarities with the Zagros-Taurus Middle Paleolithic (together with South Caucasus sites). We conclude that the Dagestan Middle Paleolithic assemblages investigated represent a local variant of the Middle Eastern Middle Paleolithic.
In the modern world, globalization leads to the active interaction of representatives of different cultures, however, there are questions of how this is reflected in the well-being level of society. This article raises the problem of the cultural heterogeneity consequences as a result of globalization. For the analysis, religion was chosen as a cultural feature (criterion of heterogeneity), which is an institution of norms and values of the population, as well as a reflection of the historical past of population. The object of research is the regions of Russia. The analysis used data from the Atlas of Religions and Nationalities of Russia «Arena» (Non-profit research based consulting "Sreda") and the Federal Agency for Ethnic Affairs. The study analyzed the influence of religious heterogeneity on the level of scientific activity of organizations in the regions of the Russian Federation. The negative influence of religious heterogeneity on the level of research activity of organizations in the regions of the Russian Federation was revealed. It is shown that the impact is not direct. Religious heterogeneity is associated with the level of migration of young scientists, which, in turn, has an impact on the activities of scientific organizations in the country.
The paper considers an approach to creating intelligent assistants in the form of chatbots that support information search based on preliminary genre and thematic clustering of website content. The tasks of finding the necessary in-formation and providing information support to the user, organizing feedback to improve the quality of the search are being solved. A feature of the approach is the use of genre models developed for a given type of resource (educational, informational, etc.), on the basis of which genre structuring of the content of a particular site is carried out. The resulting genre structures allow you to more accurately determine the boundaries of thematic clusters related to the topic of the user's search query. To provide feedback to the user, a simple script has been developed that allows not only to clarify the request, but also to implicitly get information about what exactly did not suit the user in the resulting out-put. An experimental study was conducted on the Telegram platform, the results were compared with the Yandex search engine.
Let G be a finite connected graph on n vertices with Laplacian spectrum 0 = λ1 < λ2 ≤ . . .≤ λn.The Kirchhoff index of G is defined by the formula

The aim of this paper is to find an explicit analytical formula for the Kirchhoff index of Möbius ladder graph Mn = C2n(1, n) and Prism graph P rn = Cn × P2.

The obtained formulas provide a simple asymptotical behavior of both invariants as n is going to the infinity.

The problem of maintenance of a momentless state of a composite shell with respect to parameters’ choice of reinforcement is solved. The problem of optimum design of composite pressure vessels is investigated.
The Coregonus lavaretus (Linnaeus, 1758) complex is a morphologically and genetically diverse group of whitefish. Its taxonomic structure has been controversial for almost a century. At least 25 forms of C. lavaretus have been described in Siberia, but there is still no consensus on their intraspecific structure and taxonomy. Coregonus lavaretus pidschian (Gmelin, 1789) was described as a subspecies of C. lavaretus. Recently, it was assumed that this subspecies is also a complex.

The purpose of this study was to compare the distributions of pidschian-like whitefish haplotypes in two basins of large Siberian rivers, Yenisei and Lena, and to assess the gene flow between basins of these rivers, which were connected after the last glaciation. The sequence of the following mitochondrial DNA genes, 16S rRNA (partial), tRNA-Leu (full), NADH dehydrogenase subunit 1 (full), tRNA-Ile (full), and tRNA-Gln (partial), were used for the inference of intraspecific genetic structure of C. l. pidschian.

Whitefish haplotypes were clustered into two groups according to their distribution between two large Siberian river basins; however, there were shared haplotypes indicating events of migration and hybridization, which could occur when Bolshoi Yenisei and Lena river systems were connected after the last glaciation (the Late Pleistocene).
The enhancement of Raman scattering by optical phonon modes in quantum dots was achieved in resonant and surface-enhanced Raman scattering experiments by approaching the laser energy to the energy of either the interband transitions or the localized surface plasmons in silver nanoclusters deposited onto the nanostructures. Resonant Raman scattering by TO, LO, and SO phonons as well as their overtones was observed for PbS, ZnS, and ZnO quantum dots while enhancement for LO and SO modes in CdS quantum dots with a factor of about 700 was measured in surface enhanced Raman scattering experiments. Multiple phonon Raman scattering observed up to 5th and 7th order for CdS and ZnO, respectively, confirms the high crystalline quality of the grown QDs.
One of the aims of this work is to clarify the appearance of the Kolmogorov-type energy spectrum $E(k)\ensuremath{\propto}{k}^{\ensuremath{-}5/3}$, observed in many numerical works on discrete vortex tubes and quantized vortex filaments in quantum fluids at zero temperature. Usually when explaining classical turbulent properties of quantum turbulence the model of vortex bundles is used. This model is necessary to mimic the vortex stretching, which is responsible for the energy transfer in classical turbulence.

In my consideration I do not appeal to the possible ``bundle arrangement'' but instead explore the alternative idea that the turbulent spectra appear from a singular solution, which describes the collapsing line at moments of reconnection. One more aim is related to an important and intensively discussed topic---the role of hydrodynamic collapse in the formation of turbulent spectra.

I demonstrated that the specific vortex filament configuration generated the spectrum $E(k)$ close to the Kolmogorov dependence and discussed the reason for this as well as the reason for deviation. I also discuss the obtained results from the points of view of both classical and quantum turbulence.
In this paper we construct multiparametric families of two dimensional metrics with polynomial first integral. Such integrable geodesic flows are described by solutions of some semi-Hamiltonian hydrodynamic type system. We find infinitely many conservation laws and commuting flows for this system. This procedure allows us to present infinitely many particular metrics by the generalized hodograph method.
The compound has been characterized with single-crystal X-ray diffraction, multinuclear NMR, IR, UV-vis spectrometry, CV and spectroelectrochemistry.

The clathrochelate is capable of ligand-centered two-electron reversible reduction coupled with electrochromism (in solution and thin film).
Inelastic collapse of stochastic trajectories of a randomly accelerated particle moving in half-space z>0 has been discovered by McKean [J. Math. Kyoto Univ. 2, 227 (1963)] and then independently rediscovered by Cornell et al. [Phys. Rev. Lett. 81, 1142 (1998)PRLTAO0031-900710.1103/PhysRevLett.81.1142]. The essence of this phenomenon is that the particle arrives at the wall at z=0 with zero velocity after an infinite number of inelastic collisions if the restitution coefficient β of particle velocity is smaller than the critical value β_{c}=exp(-π/sqrt[3]). We demonstrate that inelastic collapse takes place also in a wide class of models with spatially inhomogeneous random forcing and, what is more, that the critical value β_{c} is universal. That class includes an important case of inertial particles in wall-bounded random flows. To establish how inelastic collapse influences the particle distribution, we derive the exact equilibrium probability density function ρ(z,v) for the particle position and velocity. The equilibrium distribution exists only at β<β_{c} and indicates that inelastic collapse does not necessarily imply near-wall localization.
Functionality of the non-coding transcripts encoded by the human genome is the coveted goal of the modern genomics research. While commonly relied on the classical methods of forward genetics, integration of different genomics datasets in a global Systems Biology fashion presents a more productive avenue of achieving this very complex aim.

Here we report application of a Systems Biology-based approach to dissect functionality of a newly identified vast class of very long intergenic non-coding (vlinc) RNAs. Using highly quantitative FANTOM5 CAGE dataset, we show that these RNAs could be grouped into 1542 novel human genes based on analysis of insulators that we show here indeed function as genomic barrier elements.

We show that vlincRNAs genes likely function in cis to activate nearby genes. This effect while most pronounced in closely spaced vlincRNA–gene pairs can be detected over relatively large genomic distances. Furthermore, we identified 101 vlincRNA genes likely involved in early embryogenesis based on patterns of their expression and regulation. We also found another 109 such genes potentially involved in cellular functions also happening at early stages of development such as proliferation, migration and apoptosis. Overall, we show that Systems Biology-based methods have great promise for functional annotation of non-coding RNAs.

Investigation of subcooled nucleate boiling in minichannels was conducted with high speed recording optical system also equiped with high spatial resolution optics

The final stage of bubble dynamics is in good agreement with the Labuntsov correlation for spherical vapor bubble growth on a heated wall
Experimental investigations of heat transfer from the heated wall to the two-phase bubbly flow were performed in vertical annular channel using air-water system. The IR-thermography and miniature temperature sensors were used to measure heat transfer coefficients. The influence of bubbles on heat transfer is shown in comparison with the case of single phase flow. The presence of bubbles in the flow leads to heat transfer intensification in the annular channel even for low void fractions.
We experimentally and numerically study the dynamics of whispering gallery modes slowly propagating within the cladding of an optical fiber near its end facet. We demonstrated that modes reflect from the fiber cleave. The reflection coefficient appears to reach 70% for the sample under study. Use of a facet provides a simple method to confine the axial propagation of the modes.
The production of recombinant human granulocyte-colony stimulating factor (hG-CSF) for therapeutic purposes relies on its expression in selected clones of transfected mammalian cells. Alternatively, this protein can be produced by targeted secretion in the milk of transgenic goats.

After DNA microinjection of in vivo-produced pronuclear embryos was performed, two founders were obtained (one male and one female, named 10 M and 12 F, respectively). The mean level of hG-CSF secreted in the milk from the 12 F goat, which was measured during a period of induced lactation, was 620.92 ± 179.93 μg/ml. In addition, the recombinant protein presented in vitro biological activity on differentiation of human umbilical stem cells to neutrophil granulocyte series. A total of nine kids (six from 10 M and three from 12 F) that carried the hG-CSF transgene were generated by outbreeding of the founders.

In summary, we produced two transgenic goats with a stably integrated hG-CSF gene that were capable of secreting recombinant hG-CSF from the lactating mammary gland without causing any harm to the animals' health. Additionally, the founders proved to be fertile and capable of transmitting the hG-CSF gene to first generation progeny of each line. Additional investigations of the phenotypic and genotypic characteristics of the 10 M and 12 F lines are warranted.
The paper presents experimental data on synthesis of finely dispersed powder of chromium carbide Cr 3 C 2 . Chromium carbide was prepared by reduction of chromium oxide Cr 2 O 3 with nanofibrous carbon (NFC) in induction furnace in argon atmosphere. NFC is a product of catalytic decomposition of light hydrocarbons. The main characteristic of NFC is high specific surface area (~150,000 m 2 /kg), which is significantly higher than that of carbon black (~50,000 m 2 /kg). Content of impurities in NFC is at the level of 1 wt %. Based on analysis of state diagram of Cr – C system, composition of charge and the upper temperature limit of carbide formation reaction for obtaining chromium carbide in powder state are determined. Based on thermodynamic analysis, temperature of the onset of carbothermic reduction reaction of chromium oxide Cr 2 O 3 was determined at various CO pressures. Characteristics of chromium carbide were studied using X-ray diffraction analysis, pycnometric analysis, scanning electron microscopy using local energy dispersive X-ray microanalysis (EDX), lowtemperature nitrogen adsorption followed by determination of specific surface area by means of BET method, sedimentation analysis, synchronous thermogravimetry and differential scanning calorimetry (TG/DSC). The material obtained at optimal parameters is represented by a single phase – chromium carbide Cr 3 C 2 . Powder particles were predominantly aggregated. Average size of particles and aggregates equaled 6.5 μm within a wide range of size distribution. Specific surface value of the obtained samples was 2200 m 2 /kg. Oxidation of chromium carbide began at temperature of ~640 °C and practically ends at ~1000 °C. Optimum parameters of synthesis are provided by ratio of reagents according to carbide of Cr 3 C 2 composition stoichiometry at temperature of 1300 °С and holding time of 20 minutes. It is shown that for this process nanofibrous carbon is an effective reducing agent and that chromium oxide Cr 2 O 3 is almost completely reduced to carbide Cr 3 C 2 .
The main purpose of the study is to develop the calculation algorithm of energy efficiency indicators. To develop an algorithm, it is necessary to consider the features of the power supply system of the oil and gas production enterprise.

The equipment parameters identification method based on actual measurements is used for designing a mathematical model. To calculate the steady-state, the nodal-voltage method is used in couple with an addressing matrix for tracing power flows.

The algorithm considered in the paper was introduced into the information system of the production control center at the field as an additional module for assessing energy efficiency. The large deviation of the indicator's values from the specified ones is messaging about the equipment's normal mode violations. It allows creating an optimal schedule of organizational and technical measures to regulate energy consumption and improve the energy efficiency of the enterprise.
The SuUR (suppressor of underreplication) gene controls late replication and underreplication of DNA in Drosophila melanogaster polytene chromosomes: its mutation suppresses DNA underreplication whereas additional doses of the normal allele strongly enhances underreplication. The SuUR protein is localized in late replicating and underreplicating regions. The N-terminal part of the SuUR protein shares modest similarity with the ATPase/helicase domain of SWI2/SNF2 chromatin remodeling factors, suggesting a role in modification of chromatin structure. Here we describe novel structural modifications of polytene chromosomes (swellings) and show that SuUR controls chromatin organization in polytene chromosomes. The swellings develop as the result of SuUR ectopic expression in the transgene system Sgs3-GAL4; UAS-SuUR(+). They are reminiscent of chromosome puffs and appear in approximately 190 regions of intercalary, pericentric and telomeric heterochromatin; some of them attain tremendous size. The swellings are temperature sensitive: they are maximal at 29 degrees C and are barely visible at 18 degrees C. Shifting from 29 degrees C to 18 degrees C results in the complete recovery of the normal structure of chromosomes. The swellings are transcriptionally inactive, since they do not incorporate [(3)H]uridine. The SuUR protein is not visualized in regions of maximally developed swellings. Regular ecdysone-inducible puffs are not induced in cells where these swellings are apparent.
