In terms of their ore formation, these deposits correspond mainly to the orogenic type, which generally reflects specific metallogeny of the West Kalba gold-bearing belt in East Kazakhstan. Gold-quartz veins and mineralized zones of the gold-sulphide formation are confined to fractures feathering regional NW-striking and sublatitudinal faults. Their common features include the following: gold-bearing veinlet-disseminated pyrite-arsenopyrite ores that are localized in carbonaceous-sandy-schist and turbidite strata of different ages; structural-tectonic control of mineralization, numerous dikes of medium-basic compositions in ore-control zones; and the presence of post-orogenic heterochronous granite-granodiorite rocks, although their relation to gold-ore mineralization is not obvious.

We present new age constraints for igneous rocks and ore-metasomatic formations of the gold deposits in the Akzhal-Boko-Ashalin ore zone. Igneous rocks of the study area have similar ages in a narrow range from 309.1±4.1 to 298.7±3.2 Ma, which is generally consistent with the previously determined age of granitoid massifs of gold-ore fields in East Kazakhstan. A younger age (292.9±1.3 to 296.7±1.6 Ma) is estimated for felsic rocks of the dyke complex. For the ore mineralization, the 40Ar/39Ar dating of sericite from near-ore metasomatites yields two age intervals, 300.4±3.4 Ma and 279.8±4.3 Ma.

A gap between of the ages of the ore mineralization and the igneous rocks is almost 20 Ma, which may indicate that the processes of ore formation in the ore field continued in an impulse-like pattern for at least 20 Ma. Nevertheless, this confirms a relationship between the hydrothermal activity in the study area and the formation and evolution of silicic igneous rocks of the given age interval, which belong to the Kunush complex, according to previous studies. This interpretation is supported by reconstructed tectonic paleostress fields, showing that directions of the main normal stress axes changed during the ore mineralization stage, which is why the ore bodies significantly differ in their orientations. The above-mentioned data are the first age constraints for the study area. Additional age determinations are needed to further improve understanding of the chronology of ore-forming processes. Actually, all the features characterizing the gold mineralization of the Akzhal, Ashalin and Dauba ore fields, including the data on lithology, stratigraphy, structural tectonics, magmatism, isotope geochronology, mineralogy and geochemistry, can be used as criteria when searching for similar ore fields in East Kazakhstan.
The latter are derived from the analysis of the available data concerning the evaporation of polyatomic and monatomic gases [1,2].

Semi-empirical procedure of obtaining the boundary conditions for strong evaporation of a polyatomic gas is proposed. The procedure is based on specifying the dependencies of specific momentum and enthalpy of the flow from the gas flow rate.

The procedure predicts the exactly sonic terminal velocity of the flow and leads to some corrections of boundary conditions [1] in transonic region. Thus, for j=2 and sonic flow the corrected values of pressure, temperature and fraction of back-scattered molecules are about 1.007, 0.97 and 0.92 of those reported in Ref. [1].
Eingeschlossene Kohlenstoffspezies spielen eine doppelte Rolle in der nichtoxidativen Dehydroaromatisierung von Methan über Mo-Atom/ZSM-5-Katalysatoren.

In ihrer Zuschrift auf S. 1028 zeigen N. Kosinov, E. J. M. Hensen et al. mithilfe von Operando-Spektroskopie, Mikroskopie und Isotopenmarkierung von Methan, dass polycyclische aromatische Kohlenwasserstoffe, die in den Mikroporen des Zeolith-Katalysators entstehen, entscheidende Zwischenstufen auf dem Weg zu Benzol sind.

Diese Spezies desaktivieren den Katalysator durch Bildung von Ablagerungen, die den Zugang zu den Poren versperren.
On the basis of laboratory explorations the features of conducting the corrosive process in the shaft reinforcement parts under the load from lifting buckets and rock mass were determined.
Using a data sample corresponding to an integrated luminosity of 0.35 fb−1 collected by LHCb in 2011, we report the first evidence of CP violation in the decays of B0s mesons to K±π∓ pairs, ACP(B0s→Kπ)=0.27±0.08(stat)±0.02(syst), with a significance of 3.3σ. Furthermore, we report the most precise measurement of CP violation in the decays of B0 mesons to K±π∓ pairs, ACP(B0→Kπ)=−0.088±0.011(stat)±0.008(syst), with a significance exceeding 6σ.Received 29 February 2012DOI:https://doi.org/10.1103/PhysRevLett.108.201601This article is available under the terms of the Creative Commons Attribution 3.0 License.

The possibility of adaptation of a Multi-GPU, CUDA-based code for parallel computations on CPUs with the OpenMP technology is considered. By applying macros of the preprocessor of the C++ language and compiler options, the source code can be translated the GPU/CUDA, CPU/OpenMP, and Xeon Phi/OpenMP executable files. The operability of this technology is illustrated by an example of adaptation of the HyCFS code. The computational efficiency for various platforms is compared.
The predissociation dynamics of lithium iodide (LiI) in the first excited A-state is investigated for molecules in the gas phase and embedded in helium nanodroplets, using femtosecond pump-probe photoionization spectroscopy.

In the gas phase, the transient Li+ and LiI+ ion signals feature damped oscillations due to the excitation and decay of a vibrational wave packet. Based on high-level ab initio calculations of the electronic structure of LiI and simulations of the wave packet dynamics, the exponential signal decay is found to result from predissociation predominantly at the lowest avoided X-A potential curve crossing, for which we infer a coupling constant V=650(20) reciprocal cm.

The lack of a pump-probe delay dependence for the case of LiI embedded in helium nanodroplets indicates fast droplet-induced relaxation of the vibrational excitation.
We report the first observation of the radiative decay of the ϒ(1S) into a charmonium state.

These results are obtained from a 24.9 fb^{-1} data sample collected with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider at a center-of-mass energy equal to the ϒ(2S) mass using ϒ(1S) tagging by the ϒ(2S)→ϒ(1S)π^{+}π^{-} transitions.

The significance of the observed signal of ϒ(1S)→γχ_{c1} is 6.3 standard deviations including systematics. The branching fraction is calculated to be B[ϒ(1S)→γχ_{c1}]=[4.7_{-1.8}^{+2.4}(stat)_{-0.5}^{+0.4}(sys)×10^{-5}]. We also searched for ϒ(1S) radiative decays into χ_{c0,2} and η_{c}(1S,2S), and set upper limits on their branching fractions.
The process of dog domestication likely involved at least two functional stages. The initial stage occurred when subpopulations of wolves became synanthropes, benefiting from life nearby or in human environments. The second phase was characterized by the evolution of novel forms of interspecific cooperation and social relationships between humans and dogs.

Here, we discuss possible roles of the oxytocin system across these functional stages of domestication. We outline possible neurobiological changes associated with these processes and present a Siberian fox model of canid domestication in which these predictions can be tested.

We hypothesize that in early domestication, oxytocin played important roles in attenuating fear and stress associated with human contact. In later domestication, we hypothesize that oxytocin's most critical functions were those associated with affiliative social behavior, social engagement, and cooperation with humans. Lastly, we identify limitations of current studies on the neuroendocrinology of domestication and discuss challenges and opportunities for future research.

We give a complete description of solutions of the Diophantine equation.
The work deals with the experimental study of the aerodynamic structure of a swirling flow in the isothermal model of two-stage vortex combustion chamber. The main attention is focused on the process of flow mixing of two successively connected tangential swirlers of the first and second stages of the working section. Data on flow visualization are presented for two patterns of flow swirling. Time-averaged profiles of the axial and tangential velocity components are obtained with the help of laser-Doppler anemometer. In the case of flow co-swirling between two stages of the working section, instability of a secondary flow in the form of precessing vortex was distinguished. For the regime with counter flow swirling, effective mixing of the swirl flows was found; this was reflected by formation of the flow with uniform distribution of axial velocity over the cross-section.
The measured spatial distributions of the turbulent Reynolds stresses and fluxes were compared with their predictions by gradient turbulent transport models. The local values of the turbulent viscosity and turbulent diffusivity coefficients were evaluated based on Boussinesq’s and gradient diffusion hypotheses.

The present paper reports on the combined stereoscopic particle image velocimetry (PIV) and planar laser induced fluorescence (PLIF) measurements of turbulent transport for model swirl burners without combustion. Two flow types were considered, namely the mixing of a free jet with surrounding air for different swirl rates of the jet (Re = 5 × 103) and the mixing of a pilot jet (Re = 2 × 104) with a high-swirl co-flow of a generic gas turbine burner (Re = 3 × 104). The contribution of the coherent flow fluctuations to the turbulent transport was evaluated based on proper orthogonal decomposition (POD). The turbulent viscosity and diffusion coefficients were also evaluated for the stochastic (residual) component of the velocity fluctuations.

The studied flows with high swirl were characterized by a vortex core breakdown and intensive coherent flow fluctuations associated with large-scale vortex structures. The high-swirl flows with vortex breakdown for the free jet and for the combustion chamber were characterized by intensive turbulent fluctuations, which contributed substantially to the local turbulent transport of mass and momentum. Moreover, the high-swirl flows were characterized by counter-gradient transport for one Reynolds shear stress component near the jet axis and in the outer region of the mixing layer.
The main characteristics of multipole insertion devices (ID) are the first and second field integrals along an orbit trajectory in an accelerator. Such integrals of permanent magnets or traditional electromagnets insertion devices can be obtained by means of longitudinal scanning by Hall probes. Measurements of the magnetic field by Hall probes in superconducting IDs have obvious difficulties because of limited space, temperature deviation along the path, etc. Measurements of the integrals by Hall probes, especially when the integrals has to be equal to zero, it is very difficult to make with a necessary accuracy.

At Budker INP along with Hall probes the system of magnetic measurements on the basis of the tense wire with a direct current is used. The method is based on similarity of interaction of a direct current in a stretched wire and an electron beam in an accelerator with magnetic field. The stretched wire with current is a good model to describe behavior of an electron beam when passing through a magnet.

Especially the method is useful at measurement of superconducting IDs where it isn't enough space for other probes. The method provides a dynamic control of the field integrals in different modes of a magnet operation (field ramp up or down), allows to measure the integrals quickly and rather precisely.
Liver fluke causes severe liver damage in an infected human. However, the infection often remains neglected due to the lack of pathognomonic signs. Nanoparticle-enhanced magnetic resonance imaging (MRI) offers a promising technique for detecting liver lesions induced by parasites.Surface modification of iron oxide nanoparticles produced by coprecipitation from a solution of Fe3+ and Fe2+ salts using 3-aminopropylsilane (APS) was carried out. The APS-modified nanoparticles were characterized by transmission electron microscopy, fourier transform infrared spectroscopy, and thermogravimetric analysis. Magnetic resonance properties of MNPs were investigated in vitro and in vivo.The amount of APS grafted on the surface of nanoparticles (0.60±0.06 mmol g-1) was calculated based on elemental analysis and infrared spectroscopy data. According to transmission electron microscopy data, there were no essential changes in the structure of nanoparticles during the modification. The APS-modified nanoparticles exhibit high magnetic properties; the calculated relaxivity r2 was 271 mmol-1 s-1. To obtain suspension with optimal hydrodynamic characteristics, amino groups on the surface of nanoparticles were converted into an ionic form with HCl. Cellular uptake of modified nanoparticles by rat hepatoma cells and human monocytes in vitro was 74.1±4.5 and 10.0±3.7 pg [Fe] per cell, respectively. Low cytotoxicity of the nanoparticles was confirmed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and Annexin V/7-aminoactinomycin D flow cytometry assays. For the first time, magnetic nanoparticles were applied for contrast-enhanced MRI of liver lesions induced by Opisthorchis felineus.The synthesized APS-modified iron oxide nanoparticles showed high efficiency as an MRI contrast agent for the evaluation of opisthorchiasis-related liver damage.

Temperature distributions in different moments of time are obtained. Condition of tree damage by forest fire influence is under consideration in this research. Information summarized using tables with scenario and fire consequences results.
The mathematical model of the energy source describes the physical phenomena characteristic of pulsed energy supply using laser radiation.

Direct numerical modeling of the effect of the local area of energy release on the development of the combustion propagation process in a high-speed flow of a homogeneous fuel-air mixture (H2+air) has been carried out. Energy supply and ignition are simulated taking into account a given kinetic scheme.

The results on the space-time evolution of the ignition region are presented. The dependence of the position of the ignition region on the speed of the oncoming flow has been investigated.
The present work investigates the application of the plasma of glow discharge to deposit the fluoropolymer coatings. Two series of experiments were carried out in which the influence of pressure and current strength on surface coatings morphology during its surface treatment with glow discharge plasma was investigated. The surface morphology is investigated by a scanning electron microscope (SEM), and the water contact angle (WCA) is measured. The fact that the choice of pressure significantly affects the morphology and properties of the deposited coating is established.

The interaction of a detonation wave with reactive supersonic flow has been studied using detailed and reduced kinetic schemes of chemical reactions in channels of various configurations: a channel with a step, a symmetric channel with a step, and a channel with a cavity.

A mathematical technique based on the ANSYS/Fluent software has been developed to implement this interaction. Flow parameters are compared for various configurations and kinetic schemes.

It has been shown that pulsating detonation can be used to enhance ignition in supersonic flow. The possibility of using a cavity to stabilize combustion in a supersonic combustor under the impact of a detonation wave has been demonstrated.
By measuring the thermoelectric effect in high-mobility quantum wells with two occupied subbands in perpendicular magnetic field

we detect magnetophonon oscillations due to interaction of electrons with acoustic phonons. These oscillations contain specific features identified as combined resonances caused by intersubband phonon-assisted transitions of electrons in the presence of Landau quantization

The quantum theory of phonon-drag magnetothermoelectric effect, generalized to the case of multi-subband occupation, describes our experimental findings
We propose a new family of operator-orthoregressive methods for identifying the coecients of linear dierence equations from measurements of noisy solution at short time intervals.This family includes special cases of orthogonal regression (TLS) and variational identication (STLS) methods.Computational algorithms are mentioned.

The conditions of identiability, as well as quantitative indicators of local identiability, based on the numerical characteristics of the ellipsoids of deviations of the identied coecients at small disturbances in measurements, are obtained.
Comparative analysis of stereotypical behavioral patterns including elements of flexible behavior is presented, with hunting behavior of small mammals as an example. Reactions towards live prey (cockroaches) were investigated in rodents possessing different feeding specialization, in comparison with the insectivorous common shrew. Quantitative analysis was used, and Markov chains were constructed to generate schemes of stereotypes of hunting behavior in different species. The characteristic feature of hunting stereotypes in rodents is that after seizing an insect with teeth, they seize and hold it with their forepaws. This is the more evolutionary progressive feature than seizing the prey with teeth only, like shrews do. As schemes of stereotypes and tactics of hunting appeared to be similar in herbivorous narrow-headed voles and granivorous striped field mice, one can assume that these rodents possess specific adaptations to carnivorous life style. Norway rats display the less specialized hunting stereotypes. The studied rodent species demonstrate more primitive hunting stereotypes than specialized hunting rodents; however, their hunting stereotype is rather specific, and this can be considered behavioral adaptation allowing rodents to broaden feeding resources by the use of active hunting towards insects. A suggested scheme of comparative analysis of stereotypical behavior can be used in ethological and psychological studies. The study was supported by the Russian Science Foundation (grant No. 14-14-00603).
Significant importance of autoimmune changes in the pathogenesis of schizophrenia (SCZ) is not established. Here, we present the first evidence that autoantibodies of 100% SCZ patients possess RNase activity: сCMP > poly(C) > poly(A) > yeast RNA. In addition, we have got an unexpected result: there was revealed site‐specific hydrolysis of four known SCZ specific microRNAs (miR‐137, miR‐9‐5p, miR‐219‐2‐3p, and miR‐219a‐5p) playing an important role in the regulation of several genes functioning. Three major of cleavage sites are located in the microRNA loops or duplex parts directly articulated with the loops. RNase abzymes can contribute to decreasing of microRNAs effects on the functioning of numerous genes and the products of their transcription. Therefore, abzymes with RNase activity may be to some extent important for the development of schizophrenia. © 2018 IUBMB Life, 70(2):153–164, 2018
Patterns of the nonequilibrium phase transitions during propagation of an adiabatic wave phase transition in metastable refrigerants R141b, R113 and pentane C5H12 were experimentally established. Experiments were carried out in a wide range of initial temperatures and pressures in a transparent cylindrical channel. Visualization of liquids decay was performed using high-speed video camera.
A find of coesite in a kyanite graphite-diamond-bearing eclogite xenolith from the Udachnaya-Vostochnaya kimberlite pipe is described in this paper. The coesite relics were found in intensely fractured garnet indicating some influence of the kimberlite melt, which is supported by the typical secondary mineral assemblage around this inclusion. These data indicate that shallower diamond-free coesite rocks (2,7 GPa) underwent metamorphism distinct from diamond-bearing coesite eclogites (~4 GPa). The metasomatic alteration of rock interacting with C-O-H fluid during diamond crystallization may be another possible reason for the missing coesite in diamond-bearing xenoliths.
The research of the gas giant atmosphere behavior during its interaction with a stellar wind is given in paper. The various case of interaction of atmosphere with the dense gas current are considered. The numerical model based on gravitational hydrodynamics equations was used. The combination of operator splitting approach, Godunov’s and HLL methods, and the piecewise parabolic method on local stencil is used for the solution of equations. The computing experiments were made on the supercomputer equipped with Intel Xeon Phi accelerators.
The Monte Carlo simulation of the critical behavior of multilayer structures based on anisotropic Heisenberg model is performed. The influence of the uniaxial anisotropy on the critical behavior of the thin Heisenberg-like film is described. The investigation of non-equilibrium critical behavior of multilayer structure which correspond to the nanoscale superlattice Co/Cu demonstrates that the aging effects can be observed in a wider temperature range than for bulk magnetic systems.
