The presented paper contains a description of approaches to simulate processes, observed during leakage in the steam generator of the reactor with liquid metal coolant. These approaches have been implemented in thermal hydraulic code HYDRA-IBRAE/LM. To calculate motion of gas bubbles in liquid metal flow and heat transfer of gas bubbles with metal, different relations are used in HYDRA-IBRAE/LM code. The code contains models of chemical interaction between water and sodium for modelling of tube rupture in sodium cooled fast reactors, Modelling of the experiments has been made using HYDRA-IBRAE/LM code. The results of the modelling with determined main factors are presented in the article.
The energy calibration of nuclear recoil detectors is of primary importance to rare-event experiments such as those of direct dark matter search and coherent neutrino-nucleus scattering. In particular, such a calibration is performed by measuring the ionization yield of nuclear recoils in liquid Ar and Xe detection media, using neutron elastic scattering off nuclei.

In the present work, the ionization yield for nuclear recoils in liquid Ar has for the first time been measured in the higher energy range, at 80 and 233 keV, using a two-phase Cryogenic Avalanche Detector (CRAD) and DD neutron generator. The ionization yield in liquid Ar at an electric field of 2.3 kV/cm amounted to and at 80 and 233 keV, respectively.

The Jaffe model for nuclear recoil-induced ionization, in contrast to that of Thomas-Imel, can probably consistently describe the energy dependence of the ionization yield.
The article presents an analysis of the performance indicators of oil and gas companies, justification of the choice the most appropriate indicators for different company comparison. The author made and introduced indicators’ classification according to various criteria: in the form of expression, depending on the object of study and others. To compare companies, you can not use indicators which were counted by these companies because of the different structure of indicators. In this case, you need to count all indexes by your own using financial reports to make a united structure. The aim of the work is evaluation of the efficiency of companies of oil and gas complex and making a factor analysis of indicators of efficiency. To fulfill the goal author used formulas for counting indicators. One of the results of this work is that ROE (Return On Equity) is one of the most important and representative indexes because it shows how effective money of shareholders is used. It has a sense because all analyzed companies are joint-stock. Using a decomposition and factor analysis of ROE author showed that with an increase in net profit and equity at the same percentage, the return on equity is more sensitive to changes in net profit. And in the situation of decreasing the same elements, ROE is more sensitive to changes in equity.
The expression of eukaryotic genes can be regulated at several stages, including the translation of mRNA. It is known that the structure of mRNA can affect both the efficiency of interaction with the translation apparatus in general and the choice of translation initiation sites. To study the translated fraction of the transcriptome, experimental methods of analysis were developed, the most informative of which is ribosomal profiling (RP, Ribo-seq). Originally developed for use in yeast systems, this method has been adapted for research in translation mechanisms in many plant species. This technology includes the isolation of the polysomal fraction and high-performance sequencing of a pool of mRNA fragments associated with ribosomes. Comparing the results of transcript coverage with reads obtained using the ribosome profiling with the transcriptional efficiency of genes allows the translation efficiency to be evaluated for each transcript. The exact positions of ribosomes determined on mRNA sequences allow determining the translation of open reading frames and switching between the translation of several reading frames - a phenomenon in which two or more overlapping frames are read from one mRNA and different proteins are synthesized. The advantage of this method is that it provides quantitative estimates of ribosome coverage of mRNA and can detect relatively rare translation events. Using this technology, it was possible to identify and classify plant genes by the type of regulation of their expression at the transcription, translation, or both levels. Features of the mRNA structure that affect translation levels have been revealed: the formation of G2 quadruplexes and the presence of specific motifs in the 5'-UTR region, GC content, the presence of alternative translation starts, and the influence of uORFs on the translation of downstream mORFs. In this review, we briefly reviewed the RP methodology and the prospects for its application to study the structural and functional organization and regulation of plant gene expression.
We study hadronic transitions between bottomonium states using $496\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ data collected at the $\mathrm{\ensuremath{\Upsilon}}(4S)$ resonance with the Belle detector at the KEKB asymmetric energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. We measure $\mathcal{B}(\mathrm{\ensuremath{\Upsilon}}(4S)\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}\mathrm{\ensuremath{\Upsilon}}(1S))=(8.2\ifmmode\pm\else\textpm\fi{}0.5(\text{stat})\ifmmode\pm\else\textpm\fi{}0.4(\text{syst}))\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$, $\mathcal{B}(\mathrm{\ensuremath{\Upsilon}}(4S)\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}\mathrm{\ensuremath{\Upsilon}}(2S))=(7.9\ifmmode\pm\else\textpm\fi{}1.0(\text{stat})\ifmmode\pm\else\textpm\fi{}\phantom{\rule{0ex}{0ex}}0.4(\text{syst}))\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$, and $\mathcal{B}(\mathrm{\ensuremath{\Upsilon}}(4S)\ensuremath{\rightarrow}\ensuremath{\eta}\mathrm{\ensuremath{\Upsilon}}(1S))=(1.70\ifmmode\pm\else\textpm\fi{}0.23(\text{stat})\ifmmode\pm\else\textpm\fi{}0.08(\text{syst}))\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$. We measure the ratio of branching fractions $\mathcal{R}=\mathcal{B}(\mathrm{\ensuremath{\Upsilon}}(4S)\ensuremath{\rightarrow}\ensuremath{\eta}\mathrm{\ensuremath{\Upsilon}}(1S))/\mathcal{B}(\mathrm{\ensuremath{\Upsilon}}(4S)\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}\mathrm{\ensuremath{\Upsilon}}(1S))=2.07\ifmmode\pm\else\textpm\fi{}0.30(\text{stat})\ifmmode\pm\else\textpm\fi{}\phantom{\rule{0ex}{0ex}}0.11(\text{syst})$. We search for the decay $\mathrm{\ensuremath{\Upsilon}}(1{^{3}D}_{1,2})\ensuremath{\rightarrow}\ensuremath{\eta}\mathrm{\ensuremath{\Upsilon}}(1S)$, but do not find significant evidence for such a transition. We also measure the initial-state radiation production cross sections of the $\mathrm{\ensuremath{\Upsilon}}(2S,3S)$ resonances and we find values compatible with the expected ones. Finally, the analysis of the $\mathrm{\ensuremath{\Upsilon}}(4S)\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}\mathrm{\ensuremath{\Upsilon}}(1S)$ events shows indications for a resonant contribution due to the ${f}_{0}(980)$ meson.
Human alkyladenine DNA glycosylase (AAG) protects DNA from alkylated and deaminated purine lesions. AAG flips out the damaged nucleotide from the double helix of DNA and catalyzes the hydrolysis of the N-glycosidic bond to release the damaged base.

To understand better, how the step of nucleotide eversion influences the overall catalytic process, we performed a pre-steady-state kinetic analysis of AAG interaction with specific DNA-substrates, 13-base pair duplexes containing in the 7th position 1-N6-ethenoadenine (εA), hypoxanthine (Hx), and the stable product analogue tetrahydrofuran (F). The combination of the fluorescence of tryptophan, 2-aminopurine, and 1-N6-ethenoadenine was used to record conformational changes of the enzyme and DNA during the processes of DNA lesion recognition, damaged base eversion, excision of the N-glycosidic bond, and product release. The thermal stability of the duplexes characterized by the temperature of melting, Tm, and the rates of spontaneous opening of individual nucleotide base pairs were determined by NMR spectroscopy.

The data show that the relative thermal stability of duplexes containing a particular base pair in position 7, (Tm(F/T) < Tm(εA/T) < Tm(Hx/T) < Tm(A/T)) correlates with the rate of reversible spontaneous opening of the base pair. However, in contrast to that, the catalytic lesion excision rate is two orders of magnitude higher for Hx-containing substrates than for substrates containing εA, proving that catalytic activity is not correlated with the stability of the damaged base pair. Our study reveals that the formation of the catalytically competent enzyme-substrate complex is not the bottleneck controlling the catalytic activity of AAG.
Paleohygdrogeological reconstructions of the Siberian sedimentary basins suggest the presence of three water genetic types in petroleum deposits: (1) Waters that formed during marine sedimentation, (2) Waters of meteoric origin that infiltrated the basin and were involved in supergene processes in the geological past, (3) Waters produced by condensation from a hydrocarbon mixture.

The available hydrogeochemical data collected over the past four decades in Siberian Arctic areas were analyzed and interpreted comprehensively for the first time, through data ranking, evaluation and analysis, systematic estimation of region, altitude background and abnormal value, and calculation of element molar ratio, different kinds of correlation coefficients in water proximity were estimated.

Hydrogeochemical patterns of petroleum deposits are controlled by the long geological evolution in the water-rock-gas-organic matter system. Sodium-chloride bicarbonate, sodium chloride, calcium chloride groundwaters, and other types of brines with the total salinity of 0.2-350 g/L are distributed in the Siberian Arctic sedimentary basins. Comparative analysis of groundwaters and brines in the Siberian Arctic revealed a group of sodium chloride water samples had a total salinity of over 250 g/L, suggesting the formation of the brine was related to leaching of evaporite rock. Hydrogeochemical data indicate that composition of the brine has varied dramatically with their evolution. Mesozoic groundwaters and brines of Anabar-Laptev basin and West Siberia existed only in the beginning of their chemical evolution.
The hydrogeological history of the Anabar-Khatanga basin covers the period from the Archaean to the Quaternary and includes 12 hydrogeological cycles. The Jurassic-Eopleistocene cycle is the longest during which there were continental conditions of sedimentation with the longest infiltration stage (from the Lower Cretaceous to the Neo-Pleistocene). The salts of the Devonian salt basin play a key role in the formation of the groundwater and brines composition within the following structures: Nordvik, Southern Tigyan, Ilya Kozhevnikova, Ledovka and Belaya.
The Novosibirsk free electron laser is the first multi-turn energy-recovery linear accelerator with three separate laser systems (the terahertz, far-infrared and mid-infrared ones).

The facility is well equipped with optical elements and instrumentation available to Russian and foreign users.

In this paper, we describe in brief the workstations of the facility and survey selected recent experiments using intense monochromatic terahertz laser radiation, which can be tuned from 90 to 240 μm.
In the case of non-catalytic steam cracking, it was found that the use of water leads to a reduction in coke formation and, correspondingly, an increase in the yield of the target liquid products (semisynthetic oil), while reducing the sulfur content, in comparison with thermal cracking.

The catalytic steam cracking of vacuum residue (VR) in a slurry-type reactor at a temperature of 425-450 °C and 2 MPa in the presence of a Mo-based dispersed catalyst was carried out for the first time. The catalyst was introduced into the feedstock through a reverse emulsion, which was previously prepared from VR and an aqueous solution of the Mo-based precursor salt, followed by decomposition and formation of a dispersion of catalyst particles in the VR.

The results of the study also showed that the use of Mo-based dispersed catalyst increases the depth of interaction between water and VR, with an increase in the H:C ratio and a reduction in sulfur content in liquid products (semisynthetic oil).
Objective : to investigate the effect of workplace stress on cognitive functions of younger men and women (25—44 years) in an open population of Novosibirsk. Patients and methods . The study included a representative sample of Novosibirsk population aged 25—44 years (2013—2016 screening) within the budgetary theme №0541-2014-0004. We screened individuals aged 25—44years: 463 men, mean age 35.94±5.957years, and 546 women, mean age 36.17±5.997 years. Association of workplace stress with cognitive functions were assessed with standardized questions such as: «Has your specialty changed over the past 12 years?», «Do you like your job?» and «How do you rate your work responsibility over the past 12 months?». Cognitive evaluation during screening period included: A.R. Luria 10-words learning task (immediate and delayed recall), Burdon's test, exclusion of concepts «5th extra», animal naming test. Results and discussion . We observed a decrease in semantic associations number among the respondents who did not change their occupation over the past year and among respondents who assess their work responsibility as «low». Verbal logical reasoning was lower in the respondents who assumed that they «did not like» or «did not like at all» their job and also assessed their work responsibility as «low». Auditory verbal shortterm memory, long-term memory, memorization productivity, and attention were worse in the participants who had either «insignificant» or «average» work responsibility. Conclusion . Younger adults experiencing workplace stress have a decrease in cognitive functions.
Human ring chromosomes are often unstable during mitosis, and daughter cells can be partially or completely aneuploid.

We studied the mitotic stability of four ring chromosomes, 8, 13, 18, and 22, in long-term cultures of skin fibroblasts and induced pluripotent stem cells (iPSCs) by GTG karyotyping and aCGH. Ring chromosome loss and secondary aberrations were observed in all fibroblast cultures except for r(18). We found monosomy, fragmentation, and translocation of indexed chromosomes. In iPSCs, aCGH revealed striking differences in mitotic stability both between iPSC lines with different rings and, in some cases, between cell lines with the same ring chromosome. We registered the spontaneous rescue of karyotype 46,XY,r(8) to 46,XY in all six iPSC lines through ring chromosome loss and intact homologue duplication with isoUPD(8)pat occurrence, as proven by SNP genotype distribution analysis.

In iPSCs with other ring chromosomes, karyotype correction was not observed. Our results suggest that spontaneous correction of the karyotype with ring chromosomes in iPSCs is not universal and that pluripotency is compatible with a wide range of derivative karyotypes. We conclude that marked variability in the frequency of secondary rearrangements exists in both fibroblast and iPSC cultures, expanding the clinical significance of the constitutional ring chromosome.
First simulation results on interaction of a long and thin magnetized plasma column with a 100 keV electron beam are presented. Selected parameters are similar to those in the real GOL-3 experiments. To simulate the realistic problem of continuous beam injection into a plasma, we use a 2D3V particle-in cell code allowing for the open boundary conditions in the beam direction. It is shown that such a thin system appears to be unstable against the quasi-regular longitudinal density modulations and generates the fundamental and second harmonic emissions via the antenna mechanism. The radiation power of such an antenna is found to reach 0.6% of the total beam power.
A spatial mathematical model of the evaporation system using film flows has been developed. A numerical study of several modes of film flow in an evaporation cell at a heater temperature below the boiling point has been carried out. The characteristics of the film flow and the features of the coupled heat and mass transfer processes in the gas-film-metal substrate system have been studied.

Good agreement between the calculation and the experiment on the main parameters of the wave motion of the film and the heat transfer characteristics has been obtained.
Atoms in highly excited (Rydberg) states have a number of unique properties which make them attractive for applications in quantum information. These are large dipole moments, lifetimes and polarizabilities, as well as strong long-range interactions between Rydberg atoms. Experimental methods of laser cooling and precision spectroscopy enable the trapping and manipulation of single Rydberg atoms and applying them for practical implementation of quantum gates over qubits of a quantum computer based on single neutral atoms in optical traps. In this paper, we give a review of the experimental and theoretical work performed by the authors at the Rzhanov Institute of Semiconductor Physics SB RAS and Novosibirsk State University on laser and microwave spectroscopy of cold Rb Rydberg atoms in a magneto-optical trap and on their possible applications in quantum information. We also give a brief review of studies done by other groups in this area.

The local characteristics of the gas-liquid two-phase flow in rectangular microchannels 420 × 280 μm and 395 × 205 μm with T-shaped mixer inlet were experimentally investigated in this work.

Visualization of flow regimes and measurement of local characteristics were carried out using a high-speed video camera Optronis CX600x2 and laser-induced fluorescence (LIF) method. Deionized water and ethanol were used as the liquid phase, and nitrogen - as the gas phase. The Rhodamine 6G dye was added to the liquid. The location of the microchannel in space (horizontal, vertical) was changed.

The profiles of the liquid film along the long side of the microchannel were obtained, the local film thickness was measured in the channel`s central section for the elongated bubble flow and the transition flow of the deionized water-nitrogen mixture. The unevenness of liquid film thickness at the channel cross-section and along the bubble was experimentally shown. The temporal dynamics of two-phase flow for the ethanol-nitrogen mixture was shown. It was found that most of the liquid flows in the meniscus on the short side of the microchannel for the present gas and liquid flow rates.
Mobile devices are frequently used for educational purposes considering their high availability and portability. However, educational abilities of mobile devices are quite limited due to the lack of proper IDE applications. Most Android integrated development environments for C++ are lacking code completion and real-time code analysis, while others provide these features at unacceptable speeds.

Therefore, we decided to develop a next-generation mobile C++ IDE that will not only have these features, but will also provide them at real-time speeds. In this paper, we describe the software porting technology applied to Clang compiler and other required tools and propose the method to speed up compilation, code completion and code analysis in our IDE. We also propose UI optimization methods. We also describe a regular expression-based heuristic algorithm for precompiled header generation that has small processor time and RAM requirements. The efficiency of the algorithm is tested on different educational code examples.

Our experiments show that our IDE is the only one at the moment, that can keep code completion real-time in all usage scenarios. The performance gain is 300 % average, when STL is used, reaching 3350 % when Boost library is involved. There is a small performance loss when C is used, but it is not significant, as the performance is still acceptable for real-time usage. This will make mobile devices more suitable for learning C++ and will provide students with an opportunity to leave their laptops at home and to learn C++ in different situations, where usage of laptop is not convent.
В работе исследована возможность оптимизации длины ВКР-лазера со случайной распределенной обратной связью, реализованной за счет записи массива волоконных брэгговских решеток (ВБР) со случайным набором фаз и амплитуд в пассивном волокне с сохранением поляризации.

В результате была идентифицирована и удалена часть массива, вносившая большие потери, при этом длина массива ВБР уменьшилась с 13 до 6,7 м, а количество решеток в массивес 57 до 30.

В оптимизированной конфигурации пороговая мощность накачки составляет менее 1 Вт, a генерируемая мощность непрерывного линейно-поляризованного излучения на длине волны 1092 нм составляет около 3 Вт с каждого конца массива при мощности накачки 14 Вт.Ширина линии генерации при максимальной мощности составляет около 80 пм, а в припороговом режиме наблюдается одночастотная генерация с шириной <50 кГц.
We search for the flavor-changing neutral current decays D0\to mu+mu- and D0\to e+e-, and for the lepton-flavor violating decays D0\to e\pm mu\mp using 660 fb^-1 of data collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. We find no evidence for any of these decays. We obtain significantly improved upper limits on the branching fractions: B(D0\to mu+mu-)<1.4x10-7, B(D0\to e+e-)<7.9x10-8, and B(D0\to e+mu-)+B(D0\to mu+e-)<2.6x10-7 at 90% confidence level.
The cross section for the process $e^+e^- \to \omega\eta$ is measured in the center-of-mass energy range 1.34--2.00 GeV. The analysis is based on data collected with the SND detector at the VEPP-2000 $e^+e^-$ collider. The measured $e^+e^- \to \omega\eta$ cross section is the most accurate to date. A significant discrepancy is observed between our data and previous BABAR measurement.
The resonant substructure of B0s→¯D0K−π+ decays is studied with the Dalitz plot analysis technique.

The study is based on a data sample corresponding to an integrated luminosity of 3.0 fb−1 of pp collision data recorded by LHCb.

A structure at m(¯D0K−)≈2.86 GeV/c2 is found to be an admixture of spin-1 and spin-3 resonances. The masses and widths of these states and of the D∗s2(2573)− meson are measured, as are the complex amplitudes and fit fractions for all the ¯D0K− and K−π+ components included in the amplitude model. In addition, the D∗s2(2573)− resonance is confirmed to be spin 2.
