Replenishment of mineral resources, especially gold and rare metals, is critical for progress in the mining and metallurgical industry of Eastern Kazakhstan.

To substantiate the scientific background for mineral exploration, we study microinclusions in minerals from gold and rare-metal fields, as well as trace-element patterns in ores and their hosts that may mark gold and rare-metal mineralization. The analyzed samples contain rare micrometer lead (alamosite, kentrolite, melanotekite, cotunnite) and nickel (bunsenite, trevorite, gersdorffite) phases and accessory cassiterite, wolframite, scheelite, and microlite.

The revealed compositions of gold-bearing sulfide ores and a number of typical minerals (magnetite, goethite, arsenopyrite, antimonite, gold and silver) and elements (Fe, Mn, Cu, Pb, Zn, As, and Sb) can serve as exploration guides. The ores bear native gold (with Ag and Pt impurities) amenable to concentration by gravity and flotation methods. Multistage rare-metal pegmatite mineralization can be predicted from the presence of mineral assemblages including cleavelandite, muscovite, lepidolite, spodumene, pollucite, tantalite, microlite, etc. and such elements as Ta, Nb, Be, Li, Cs, and Sn. Pegmatite veins bear diverse Ta minerals (columbite, tantalite-columbite, manganotantalite, ixiolite, and microlite) that accumulated rare metals late during the evolution of the pegmatite magmatic system. The discovered mineralogical and geochemical criteria are useful for exploration purposes.
Using a data sample of $980\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of ${e}^{+}{e}^{\ensuremath{-}}$ annihilation data taken with the Belle detector operating at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider, we report the results of a study of the decays of the ${\mathrm{\ensuremath{\Omega}}}_{c}^{0}$ charmed baryon into hadronic final states. We report the most precise measurements to date of the relative branching fractions of the ${\mathrm{\ensuremath{\Omega}}}_{c}^{0}$ into ${\mathrm{\ensuremath{\Omega}}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{0}$, ${\mathrm{\ensuremath{\Omega}}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$, ${\mathrm{\ensuremath{\Xi}}}^{\ensuremath{-}}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{+}$, and ${\mathrm{\ensuremath{\Xi}}}^{0}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$, as well as the first measurements of the branching fractions of the ${\mathrm{\ensuremath{\Omega}}}_{c}^{0}$ into ${\mathrm{\ensuremath{\Xi}}}^{\ensuremath{-}}{\overline{K}}^{0}{\ensuremath{\pi}}^{+}$, ${\mathrm{\ensuremath{\Xi}}}^{0}{\overline{K}}^{0}$, and $\mathrm{\ensuremath{\Lambda}}{\overline{K}}^{0}{\overline{K}}^{0}$, all with respect to the ${\mathrm{\ensuremath{\Omega}}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$ decay. In addition, we investigate the resonant substructure of these modes. Finally, we present a limit on the branching fraction for the decay ${\mathrm{\ensuremath{\Omega}}}_{c}^{0}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Sigma}}}^{+}{K}^{\ensuremath{-}}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$.
The problem of studying the development of stroke in men of working age working in conditions of high occupational risk is relevant. The aim of the study was to develop a method for predicting the development of stroke in men working under the influence of electromagnetic fields of industrial frequency.

We examined 98 men who had professional contact with the factor of electromagnetic radiation (EMI) of industrial frequency, aged 30 to 65 years, with work experience of 5 years or more. Two groups were identified: the first group — 56 stroke patients, the second group — 42 men diagnosed with chronic cerebral ischemia. Using the method of sequential inclusion of the studied risk factors (ForwardStepwise), those that made an independent significant contribution to the development of stroke were selected. Based on the results obtained, a logistic regression formula was created that determines the probability of stroke in patients working on installation, repair, maintenance of electrical networks and electrical equipment.

The presence of influence on stroke development of the following factors was established: patient’s age (β-coefficient=–0,112, p=0,013), total cholesterol level (β-coefficient=0,782, p=0,009), smoking factor (β-coefficient=–2,8, p=0,001), alcohol abuse factor (β-coefficient=3,84, p=0,0001), presence of arterial hypertension of 2–3 degrees (β-coefficient=2,63, p=0,002). In the patient, the values of these 5 parameters are determined, then these values are substituted into the appropriate formula to calculate the value of p (X). A p (X) value greater than 0.32 indicates a high risk of stroke. The sensitivity of the proposed method was 71.4%, specificity–73.8%. The proposed method for predicting the development of stroke in men whose professional activity is associated with the installation, repair, maintenance of electrical networks and electrical equipment, can be used in medical practice: the patient is determined by the value of 5 parameters (patient’s age, total cholesterol, a history of exposure to smoke, factors alcohol abuse, arterial hypertension of 2–3 degrees), then these values are substituted into the appropriate formula. The calculation of the p (X) value can be implemented in the Excel table processor
We theoretically analyze the contrast observed at the outcrop of a threading dislocation at the GaN(0001) surface in cathodoluminescence and electron-beam induced current maps.

We consider exciton diffusion and recombination including finite recombination velocities both at the planar surface and at the dislocation. Formulating the reciprocity theorem for this general case enables us to provide a rigorous analytical solution of this diffusion-recombination problem.

The results of the calculations are applied to an experimental example to determine both the exciton diffusion length and the recombination strength of threading dislocations in a free-standing GaN layer with a dislocation density of $6\times10^{5}$~cm$^{-2}$.
Background Threshability, rachis fragility and spike shape are critical traits for the domestication and evolution of wheat, determining the crop yield and efficiency of the harvest. Spelt factor gene Q controls a wide range of domestication-related traits in polyploid wheats, including those mentioned above.

The main goal of the present study was to characterise the Q gene for uninvestigated accessions of wheats, including four endemics, and Aegilops accessions, and to analyze the species evolution based on differences in Q gene sequences. Results We have studied the spike morphology for 15 accessions of wheat species, including four endemics, namely Triticum macha , T. tibetanum , T. aestivum ssp. petropavlovskyi and T. spelta ssp. yunnanense , and 24 Aegilops accessions, which are donors of B and D genomes for polyploid wheat. The Q-5A , q-5D and q-5S genes were investigated, and a novel allele of the Q-5A gene was found in accessions of T. tibetanum (KU510 and KU515). This allele was similar to the Q allele of T. aestivum cv. Chinese Spring but had an insertion 161 bp in length within exon 5. This insertion led to a frameshift and premature stop codon formation. Thus, the T. tibetanum have spelt spikes, which is probably determined by the gene Tg , rather than Q. We determined the variability within the q-5D genes among hexaploid wheat and their D genome donor Aegilops tauschii. Moreover, we studied the accessions C21–5129, KU-2074, and K-1100 of Ae. tauschii ssp. strangulata , which could be involved in the origin of hexaploid wheats.

Conclusions The variability and phylogenetic relationships of the Q gene sequences studied allowed us to clarify the relationships between species of the genus Triticum and to predict the donor of the D genome among the Ae. tauschii accessions. Ae. tauschii ssp. strangulata accessions C21–5129, KU-2074 and K-1100 are the most interesting among the analysed accessions, since their partial sequence of q-5D is identical to the q-5D of T. aestivum cv. Chinese Spring. This result indicates that the donor is Ae. tauschii ssp. strangulata but not Ae. tauschii ssp . tauschii. Our analysis allowed us to clarify the phylogenetic relationships in the genus Triticum .
Whereas modern automated blood cell analyzers measure the volume of individual red blood cells (RBCs), leading to four RBC indices (mean corpuscular volume, MCV; mean corpuscular hemoglobin, MCH; mean corpuscular hemoglobin concentration, MCHC; red cell distribution width, and RDW), the RBC shape has not been assessed by clinical screening tools.

We applied the scanning flow cytometer (SFC) for complete characterization of intact RBC morphology in terms of diameter, maximal and minimal thicknesses, volume, surface area, sphericity index, spontaneous curvature, hemoglobin concentration, and content. The above‐mentioned individual RBC characteristics were measured without fluorescent markers and other chemicals by a SFC equipped only with 660 nm laser for RBC illumination and single detector for measurement of angle‐resolved light scattering. The distributions over all RBC characteristics were constructed and processed statistically to form the novel 31 RBC indices for 22 donor samples.

Our results confirm the possibility of precise, label‐free, enhanced morphological analysis of individual intact RBCs with compact single‐detector flow cytometer. Detailed characterization of RBCs with high statistics and precision can be used to increase the value of screening examinations and to reveal pathologies accompanied by abnormality of RBC shape.
Novosibirsk Scientific Center (NSC), also known worldwide as Akademgorodok, is one of the largest Russian scientific centers hosting Novosibirsk State University (NSU) and more than 35 research organizations of the Siberian Branch of Russian Academy of Sciences including Budker Institute of Nuclear Physics (BINP), Institute of Computational Technologies (ICT), and Institute of Computational Mathematics and Mathematical Geophysics (ICM&MG). Since each institute has specific requirements on the architecture of the computing farms involved in its research field, currentiy we've got several computing facilities hosted by NSC institutes, each optimized for the particular set of tasks, of which the largest are the NSU Supercomputer Center, Siberian Supercomputer Center (ICM&MG), and a Grid Computing Facility of BINP. Recendy a dedicated optical network with the initial bandwidth of 10 Gbps connecting these three facilities was built in order to make it possible to share the computing resources among the research communities of participating institutes, thus providing a common platform for building the computing infrastructure for various scientific projects. Unification of the computing infrastructure is achieved by extensive use of virtualization technologies based on XEN and KVM platforms. The solution implemented was tested thoroughly within the computing environment of KEDR detector experiment which is being carried out at BINP, and foreseen to be applied to the use cases of other HEP experiments in the upcoming future.
Genome-wide association studies have led to a significant progress in identification of genomic loci affecting coronary artery disease (CAD) risk. However, revealing the causal genes responsible for the observed associations is challenging.

In the present study, we aimed to prioritize CAD-relevant genes based on cumulative evidence from the published studies and our own study of colocalization between eQTLs and loci associated with CAD using SMR/HEIDI approach. Prior knowledge of candidate genes was extracted from both experimental and in silico studies, employing different prioritization algorithms.

Our review systematized information for a total of 51 CAD-associated loci. We pinpointed 37 genes in 36 loci. For 27 genes we infer they are causal for CAD, and for 10 further genes we judge them most likely causal. Colocalization analysis showed that for 18 out of these loci, association with CAD can be explained by changes in gene expression in one or more CAD-relevant tissues. Furthermore, for 8 out of 36 loci, existing evidence suggested additional CAD-associated genes. For the remaining 15 loci, we concluded that evidence for gene prioritization remains inconsistent, insufficient, or absent. Our results provide deeper insights into the genetic etiology of CAD and demonstrate knowledge gaps where further research is warranted.
Composite TiO2/activated carbon (TiO2/AC) and TiO2/SiO2 photocatalysts with TiO2 contents in the 10 to 80 wt. % range were synthesized by the TiOSO4 thermal hydrolysis method and characterized by AES, BET, X-ray diffraction and FT-IR ATR methods. All TiO2 samples were in the anatase form, with a primary crystallite size of about 11 nm. The photocatalytic activities of the TiO2/AC and TiO2/SiO2 samples were tested in the gas-phase photocatalytic oxidation (PCO) reaction of diethyl sulfide (DES) vapor in a static reactor by the FT-IR in situ method. Acetaldehyde, formic acid, ethylene and SO2 were registered as the intermediate products which finally were completely oxidized to the final oxidation products – H2O, CO2, CO and SO42− ions. The influence of the support on the kinetics of DES PCO and on the TiO2/AC and TiO2/SiO2 samples’ stability during three long-term DES PCO cycles was investigated. The highest PCO rate was observed for TiO2/SiO2 photocatalysts. To evaluate the activity of photocatalysts the turnover frequency values (TOF) were calculated for three photocatalysts (TiO2, TiO2/AC and TiO2/SiO2) for the same amount of mineralized DES. It was demonstrated that the TOF value for composite TiO2/SiO2 photocatalysts was 3.5 times higher than for pure TiO2.
This paper presents the results of numerical simulation of steam bubble growth in a uniformly superheated liquid.

The numerical calculation scheme takes into account both inertial and thermal effects. The main regularities of the prosses are discussed by the example of different superheat levels and different liquids: water, mercury and glycerin.

Simple estimations of characteristic times of the inertial and transition stages are offered.
Due to strong sextupole corrections, the vertical dynamic aperture of a low-emittance storage ring is rather small. Therefore, in-vacuum short-period undulators can provide a sufficiently high field. In particular, a significant electrostatic field value can be obtained near electrodes.

To eliminate the field emission, the high-field surfaces should be at a positive electric potential. In this paper, we consider the feasibility of an undulator using a comb of such electrodes.

It is worth noting that a variable-period design may be rather simple for electrostatic undulators.
The one-dimension Russo--Smereka kinetic equation describing the propagation of nonlinear concentration waves in a rarefied bubbly fluid is considered. Reductions of the model to finite component systems are derived. Stability of the bubbly flow in terms of hyperbolicity of the kinetic equation is studied. Conservation form of the model is proposed and numerical solution of the Cauchy problem with discontinuous initial data is obtained.
Smallpox was the first human disease to be eradicated, through a concerted vaccination campaign led by the World Health Organization. Since its eradication, routine vaccination against smallpox has ceased, leaving the world population susceptible to disease caused by orthopoxviruses. In recent decades, reports of human disease from zoonotic orthopoxviruses have increased. Furthermore, multiple reports of newly identified poxviruses capable of causing human disease have occurred. These facts raise concerns regarding both the opportunity for these zoonotic orthopoxviruses to evolve and become a more severe public health issue, as well as the risk of Variola virus (the causative agent of smallpox) to be utilized as a bioterrorist weapon. The eradication of smallpox occurred prior to the development of the majority of modern virological and molecular biological techniques. Therefore, there is a considerable amount that is not understood regarding how this solely human pathogen interacts with its host. This paper briefly recounts the history and current status of diagnostic tools, vaccines, and anti-viral therapeutics for treatment of smallpox disease. The authors discuss the importance of further research to prepare the global community should a smallpox-like virus emerge.
A search for a heavy neutral Higgs boson, A , decaying into a Z boson and another heavy Higgs boson, H , is performed using a data sample corresponding to an integrated luminosity of 139 fb $$^{-1}$$ -1 from proton–proton collisions at $$\sqrt{s} = 13$$ s=13 $$\text {TeV}$$ TeV recorded by the ATLAS detector at the LHC. The search considers the Z boson decaying into electrons or muons and the H boson into a pair of b -quarks or W bosons. The mass range considered is 230–800 $$\text {GeV}$$ GeV for the A boson and 130–700 $$\text {GeV}$$ GeV for the H boson. The data are in good agreement with the background predicted by the Standard Model, and therefore 95% confidence-level upper limits for $$\sigma \times B(A\rightarrow ZH)\times B(H\rightarrow bb \; \text {or} \; H \rightarrow WW)$$ σ×B(A→ZH)×B(H→bborH→WW) are set. The upper limits are in the range 0.0062–0.380 pb for the $$H\rightarrow bb$$ H→bb channel and in the range 0.023–8.9 pb for the $$H\rightarrow WW$$ H→WW channel. An interpretation of the results in the context of two-Higgs-doublet models is also given.
NFC is a product of catalytic decomposition of light hydro carbons. The main characteristic of a NFC is high specific surface area (~150,000 m 2 /kg), which is significantly higher than that of soot (~50,000 m 2 /kg). The content of impurities in NFC is about 1 wt %. Boron carbide used as a reagent is characterized by high dispersity (at the level of ~2 μm) and insignificant content of impurities – no more than 1.5 wt %. Based on analysis of state diagram of the Cr – B system, composition of the charge and upper temperature limit of diboride formation reaction were determined for obtaining chromium diboride in powder state.

Chromium diboride was prepared by reduction of chromium oxide Cr 2 O 3 with nanofibrous carbon (NFC) and boron carbide in the induction furnace under argon atmosphere. According to the results of thermodynamic analysis, the temperature of beginning of reaction for chromium oxide Cr 2 O 3 reduction by carbon and boron carbide was determined at various CO pressures. Composition and characteristics of chromium diboride were studied using X-ray phase analysis, inductively coupled plasma atomic emission spectrometry (AES-ISP), scanning electron microscopy using local energy-dispersive X-ray microanalysis (EDX), low-temperature adsorption of nitrogen, followed by determination of specific surface area by BET method, sedi mentation analysis, synchronous thermogravimetry and differential scanning calorimetry (TG/DSC).

The material obtained at optimal parameters is represented by a single phase – chromium diboride CrB 2 . The content of impurities in chromium diboride does not exceed 2.5 wt %. The powder particles were predominantly aggregated. The average size of the particles and aggregates is equal to 7.95 μm within a wide range of size distribution. The specific surface area of a single-phase sample is 3600 m 2 /kg. Oxidation of chromium diboride begins at a temperature of 430 °C and when the temperature reaches 1000 °C, the degree of oxidation is approximately 25 %. Optimum synthesis parameters are the ratio of reagents according to stoichiometry to obtain chromium diboride at a temperature of 1700 °C and holding time of 20 min. 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 diboride CrB 2 .
The primary objective of personalized vaccination is to induce an efficient immune defense while avoiding excessive immunization. Hence, it necessitates the development of methods for predicting the magnitude of the immune response prior to vaccination. Telomere length can be considered as a promising prognostic parameter for assessing the immune response to vaccination. The aim of the work was to analyze the possible association between leukocyte telomere length and specific antibody levels after vaccination against tick-borne encephalitis. The study included 55 men and 40 women who had not previously been vaccinated against tick-borne encephalitis and had no contacts with ticks. Vaccination was carried out with the EnceVir vaccine. One month after vaccination, the level of specific IgG antibodies against tick-borne encephalitis virus was analyzed using the VektoVKE-IgG-strip test system and leukocyte telomere length was measured using real-time quantitative PCR. According to the intensity of vaccine-elicited immune responses, patients were divided into three groups: unresponsive (IgG level 0–100 IU/ml), slightly responsive (IgG level 101–200 IU/ml) and highly responsive (IgG level above 200 IU/ml). The telomere length, at least at trend level ( p < 0.1), correlated with the response to vaccination as well as age, educational level and the presence of emotional stress. Using a general linear model, an association between telomere length and immune response to vaccination against tick-borne encephalitis at trend level ( p < 0.1) was found only in women. Using a pairwise comparison, it was found that telomere length was significantly higher in highly responsive women than in unresponsive women. Hence, an association between leukocyte telomere length and specific antibody levels after vaccination against tick-borne encephalitis was identified in women. Therefore, peripheral blood leukocyte telomere length can be considered as a promising marker for predicting lymphocyte proliferative responses and the magnitude of vaccine-elicited cellular immune responses.
Light field cameras have some advantages over classic cameras in a narrow field of application, such photography, cinematography surveillance and quality control in industry. Light field cameras have larger depth of field, compare to regular camera, but lower spatial resolution along optical axis then binocular system. However, 3D velocity measurements using light field are reasonable alternative to modern 3D PIV measurements. The nature of light field image requires extra reconstruction step which affects overall accuracy. In this article, light field PTV was compared to Tomo-PIV. Both techniques were used to measure 3D velocity fields in a turbulent wake past confined cylinder.
Chronic agonistic interactions promote the development of experimental psychopathologies in animals: a depression-like state in chronically defeated mice and the pathology of aggressive behavior in the mice with repeated wins. The abundant research data indicate that such psychopathological states are associated with significant molecular and cellular changes in the brain.

This paper aims to study the influence of a 20-day period of agonistic interactions on the expression patterns of collagen family genes encoding the proteins which are basic components of extracellular matrix (ECM) in different brain regions of mice using the RNA-Seq database.

Most of differentially expressed collagen genes were shown to be upregulated in the hypothalamus and striatum of chronically aggressive and defeated mice and in the hippocampus of defeated mice, whereas downregulation of collagen genes was demonstrated in the ventral tegmental areas in both experimental groups. Aberrant expression of collagen genes induced by chronic agonistic interactions may be indicative of specific ECM defects in the brain regions of mice with alternative social experience. This is the first study demonstrating remodeling of ECM under the development of experimental disorders.
