The article presents the results of the examination of the Tolerance-intolerance of ambiguity new questionnaire on the sample of 505 subjects. The three factor model, suggested by T.V. Kornilova, demonstrated poor fit to the data. The exploratory factor analysis did not reveal the factor structure of the questionnaire. The results could be explained due to samples differences. The role of additional variables determining the dimension of the construct is discussed.
Recent works by the authors have shown the high efficiency of using thin liquid films, moving under the action of gas in a flat mini-channel, for removing high heat fluxes. In the present work, we carefully study the total heat losses in such a system. Total heat losses are divided into two portions: heat losses from the heating coil to the atmosphere and heat spreadings from the heater to the substrate. The relative values of the total heat losses prior to the crisis are decreasing with increasing critical heat flux and do not exceed approximately 20% for the critical heat flux between 500 and 900 W/cm 2 .
Spin-labelled compounds are widely used in chemistry, physics, biology, and material sciences, but the directed synthesis of some functionalized organic radicals is still a challenge.

We succeeded in the preparation of a tetrazolyl-substituted nitronyl nitroxide radical in pure crystalline form. According to the single-crystal X-ray data, intra- (NH…O, 2.43 Å) and inter-molecular hydrogen bonds (NH…O, 1.91 Å) are formed between NH groups of the tetrazole cycles and O atoms of the paramagnetic moieties. The intermolecular H-bonds connect the molecules forming chains along the a-axis. Moreover, there are short intermolecular contacts between the O atoms (3.096 Å) and between the O and C atoms (3.096 Å) of the nitronyl nitroxide moieties within the chain. The spin-unrestricted broken-symmetry calculations performed at the BS-UB3LYP/def2-TZVP level of theory predicted a sufficient ferromagnetic interaction (J ≈ 20 cm–1) between the adjacent radicals inside the chain, but a weak antiferromagnetic interaction (−J ≤0.2 cm−1) between the nearest radicals belonging to the different chains.

Thus, a rare case when stable radicals, the tetrazolyl-substituted nitronyl nitroxides, are ordered into ferromagnetic chains was revealed; an investigation of the magneto-structural correlations inherent in the nitroxide radical will demand a special experiment in the sub-Kelvin regime.
Localization of a set of chimeric GFP proteins in D. melanogaster spermatogenesis has been studied. In the collection used, the proteins with detectable germ-line expression frequently occur to be involved in mRNA maturation.

According to the cellular localization, proteins fall into three groups, namely, the protein Rtc1, involved in splicing, displays an exclusively nuclear localization; the proteins Squid (splicing and mRNA transport), Pabp2 (polyadenylation), and Hrb98DE (splicing and mRNA transport) change their localization during germ-line development; and the protein Imp (mRNA localization) is located exclusively in the cytoplasm.

The distribution of Rtc1, Squid and Hrb98DE in the spermatocyte nuclei is morphologically similar to the distribution of splicing bodies, the so-called splicing factor compartments. The proteins Imp and Hrb98DE at the stage of elongation are localized to a specialized structure in the caudal region of cyst; this region corresponds to the site of the highest synthetic activity in the cyst cells at this developmental stage.
Practical application of central aortic pressure (CAP) parameters is limited by the absence of generally recognized reference and threshold diagnostic indices.

A total of 327 people were examined: 155 men and 172 women aged 25–44 years from a representative sample from the general population of Novosibirsk. Applanation tonometry of the radial artery was performed by the SphygmoCor system. The reference values of CAP parameters were obtained by a nonparametric method according to the Clinical and Laboratory Standards Institute (CLSI) recommendations (95 % percentile interval with 2.5 % and 97.5 % cut-off points and their 90 % confidence intervals). Diagnostic thresholds and categories of CAP were determined as mean values depending on the categories of brachial arterial pressure (BP) and on the basis of risk estimates, as well as sensitivity and specificity values for left ventricular hypertrophy similar to risk and sensitivity and specificity values of threshold levels (categories) of brachial BP.

The reference values of the parameters of the CAP were: 18–43 mm Hg for pulse pressure; 5–24 mm Hg for the amplification of pulse pressure; – 8.8–40 % for the augmentation index. Diagnostic categories of CAP were determined to be: optimal – less than 110 / 80, normal – 110 / 80–114 / 84, high normal – 115 / 85–124 / 89, hypertension – more than 125 / 90 mm Hg. The reference values, diagnostic thresholds and categories of parameters of CAP in the general population of Novosibirsk aged 25–44 years have been determined. It is expedient to further study them.
Experimental data on the nonlinear wave train development in 3D supersonic boundary layer over swept wing and experimental investigation of wave train development in spanwise modulated boundary layer on flat plate and swept wing at Mach number 2 and 2.5 are presented. Artificial disturbances in the boundary layer were excited by periodical glow discharge mainly at 10 and 20 kHz. It was found, that some disturbance excitation downstream cannot be explained by linear stability theory. It was obtained that receptivity of supersonic boundary layer to the surface excited controlled pulsations and the wave train development essentially depends on the Mach number.
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.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.Computational algorithms are mentioned.
In this work, the sensor response of MPcFx (M = Cu, Co, Zn; x = 0, 4, 16) films toward gaseous NH₃ (10⁻50 ppm) was studied by a chemiresistive method and compared to that of unsubstituted MPc films to reveal the effects of central metals and F-substituents on the sensing properties.

A combination of atomic force microscopy and X-ray diffraction techniques have been used to elucidate the structural features of thin MPcFx films deposited by organic molecular beam deposition. It has been shown that the sensor response of MPcF₄ films to ammonia is noticeably higher than that of MPc films, which is in good correlation with the values of binding energy between the metal phthalocyanine and NH₃ molecules, as calculated by the density functional theory (DFT) method.

At the same time, in contrast to the DFT calculations, MPcF16 demonstrated the lesser sensor response compared with MPcF₄, which appeared to be connected with the different structure and morphology of their films. The ZnPcF₄ films were shown to exhibit a sensitivity to ammonia up to concentrations as low as 0.1 ppm, and can be used for the selective detection of ammonia in the presence of some reducing gases and volatile organic compounds. Moreover, the ZnPcF₄ films can be used for the detection of NH₃ in the gas mixture simulating exhaled air (N₂ 76%, O₂ 16%, H₂O 5%, and CO₂ 3%).
The effect of weak axisymmetric magnetic and/or electrostatic perturbations on the equilibrium of a non-neutral plasma in a Malmberg-Penning trap is analyzed.

A semi-analytic solution for the potential variations inside the trap is found in a paraxial limit of the perturbations for the case of global thermal equilibrium.

The fraction of magnetically and electrostatically trapped particles is calculated for a bi-Maxwellian distribution function.
Bread wheat (Triticum aestivum) inflorescences, or spikes, are characteristically unbranched and normally bear one spikelet per rachis node. Wheat mutants on which supernumerary spikelets (SSs) develop are particularly useful resources for work towards understanding the genetic mechanisms underlying wheat inflorescence architecture and, ultimately, yield components.

Here, we report the characterization of genetically unrelated mutants leading to the identification of the wheat FRIZZY PANICLE (FZP) gene, encoding a member of the APETALA2/Ethylene Response Factor transcription factor family, which drives the SS trait in bread wheat. Structural and functional characterization of the three wheat FZP homoeologous genes (WFZP) revealed that coding mutations of WFZP-D cause the SS phenotype, with the most severe effect when WFZP-D lesions are combined with a frameshift mutation in WFZP-A.

We provide WFZP-based resources that may be useful for genetic manipulations with the aim of improving bread wheat yield by increasing grain number.
Актуальность исследования обусловлена получением новых данных по изотопной геохимии сверхкрепких рассолов Сибирской платформы. Цель: выявить особенности генезиса рассолов и растворенной в них углекислоты, а также взаимодействия вод с окружением. Методы. Полевое опробование проведено в соответствии с общепринятыми методиками. Химико-аналитические исследования выполнены методами титриметрии, ионной хроматографии и масс-спектрометрии с индуктивно связанной плазмой. Определение δD, δ18O, δ13С проводилось на приборе Isotope Ratio Mass Spectrometer FinniganTM MAT 253, снабженном приставками пробоподготовки H/Device (для анализа δD) и GasBench II (для анализа δ18O и δ13СDIC). Изотопные отношения 87Sr86/Sr и 87Rb/86Sr изучались на масс-спектрометре MI 1201T в двухленточном режиме с регистрацией на одном коллекторе. Результаты. Представлены новые изотопно-геохимические данные по сверхкрепким рассолам Сибирской платформы широкого стратиграфического диапазона (от рифея до ордовика). Для изученных рассолов характерен широкий интервал относительных концентраций дейтерия и кислорода-18: от –133 до –17,5 ‰ для δD и от –17,0 до –2,5 ‰ для δ18O. На основании значений кислородных и водородных дельт рассолов предполагается их седиментационно-метаморфический генезис. Значения δ13С для DIC рассолов варьируют в диапазоне от –31 до +12,7 ‰. Предполагается биогенное (бактериальное) происхождение растворенной в водах углекислоты. В среднем переход от более молодых комплексов к более древним сопровождается обогащением DIC легким изотопом углерода. Стронциевые отношения изученных рассолов делят их на две группы: с отношениями 87Sr/86Sr, близкими к значениям в водах современного океана, и со значениями 87Sr/86Sr, существенно их превышающими. Предполагается, что для рассолов второй группы захоронение вод происходило в присутствии обломочного материала выветривания континентальной коры, обогащенного радиоактивным 87Rb.
U–Pb geochronological, trace‐element and Lu–Hf isotopic studies have been made on zircons from ultrahigh‐pressure (UHP) mafic eclogite from the Kumdy‐Kol area, one of the diamond‐facies domains of the Kokchetav Massif (northern Kazakhstan). The peak eclogitic assemblage equilibrated at > 900 °C, whereas the bulk sample composition displays light rare‐earth element (LREE) and Th depletion evident of partial melting. Zircons from the eclogite are represented by exclusively newly formed metamorphic grains and have U–Pb age spread over 533–459 Ma, thus ranging from the time of peak subduction burial to that of the late post‐orogenic collapse. The major zircon group with concordant age estimates have a concordia age of 508.1 ±4.4 Ma, which corresponds to exhumation of the eclogite‐bearing UHP crustal slice to granulite‐ or amphibolite‐facies depths. This may indicate potentially incoherent exhumation of different crustal blocks within a single Kumdy‐Kol UHP domain. Model Hf isotopic characteristics of zircons (ε Hf (t) +1.5 to +7.8, Neoproterozoic model Hf ages of 1.02–0.79 Ga) closely resemble the whole‐rock values of the Kumdy‐Kol eclogites and likely reflect in situ derivation of HFSE source for newly formed grains. The ages coupled with geochemical systematics of zircons confirm that predominantly late zircon growth occurred in Th–LREE‐depleted eclogitic assemblage, that experienced incipient melting and monazite dissolution in melt at granulite‐facies depths, followed by amphibolite‐facies rehydration during late‐stage exhumation‐related retrogression.

A combination of the searches for pair-produced vector-like partners of the top and bottom quarks in various decay channels ($T$$\rightarrow$$Zt/Wb/Ht$, $B$$\rightarrow$$Zb/Wt/Hb$) is performed using 36.1 fb$^{-1}$ of $pp$ collision data at $\sqrt{s}$ = 13 TeV with the ATLAS detector at the Large Hadron Collider. The observed data are found to be in good agreement with the Standard Model background prediction in all individual searches. Therefore, combined 95% confidence-level upper limits are set on the production cross-section for a range of vector-like quark scenarios, significantly improving upon the reach of the individual searches. Model-independent limits are set assuming the vector-like quarks decay to Standard Model particles. A singlet $T$ is excluded for masses below 1.31 TeV and a singlet $B$ is excluded for masses below 1.22 TeV. Assuming a weak isospin $(T,B)$ doublet and $|V_{Tb}| \ll |V_{tB}|$, $T$ and $B$ masses below 1.37 TeV are excluded.
Forced high-frequency vibrations of the airfoil surface part with the amplitude almost equal to the sound velocity can change significantly the lift force of the symmetric profile streamlined at zero angle of attack.

The oscillation consists of two harmonics. The ratio of harmonics frequencies values is equal to 2.

The present work shows that the aerodynamic properties depend significantly on the specific energy contribution of each frequency.
C57Bl mice exhibit impaired glucose metabolism by the late adult age under standard living conditions.

The aim of this study was to evaluate white adipose tissue (WAT), brown adipose tissue (BAT), and skeletal muscle expression of genes involved in carbohydrate-lipid metabolism at postpubertal stages preceding the late adult age in C57Bl mice. Muscle mRNA levels of uncoupling protein 3 (Ucp3) and carnitine palmitoyltransferase 1 (Cpt1) (indicators of FFA oxidation), WAT mRNA levels of hormone-sensitive lipase (Lipe) and lipoprotein lipase (Lpl) (indicators of lipolysis and lipogenesis), muscle and WAT mRNA levels of the type 4 glucose transporter Slc2a4 (indicators of insulin-dependent glucose uptake), and BAT mRNA levels of uncoupling protein 1 (Ucp1) (indicator of thermogenesis) were measured in fed and 16 h-fasted mice in three age groups: 10-week-old (young), 15-week-old (early adult), and 30-week-old (late adult).

Weight gain from young to early adult age was not accompanied by changes in WAT and BAT indexes and biochemical blood parameters. Weight gain from early to late adult age was accompanied by increased WAT and BAT indexes and decreased glucose tolerance. Muscle Ucp3 and Cpt1 mRNA levels and WAT Lipe and Slc2a4 mRNA levels increased from young to early adult age and then sharply decreased by the late adult age. Moreover, BAT Ucp1 mRNA level decreased in the late adult age. Fasting failed to increase muscle Cpt1 mRNA levels in late adult mice. These transcriptional changes could contribute to impaired glucose metabolism and the onset of obesity in late adult mice during normal development.
Coronaviruses (CoVs) belong to the subfamily Orthocoronavirinae of the family Coronaviridae. CoVs are enveloped (+) RNA viruses with unusually long genomes. Severe acute respiratory syndrome CoV (SARS-CoV), Middle East respiratory syndrome CoV (MERS-CoV), and the novel coronavirus (2019-nCoV, SARS-CoV-2) have been identif ied as causing global pandemics. Clinically tested vaccines are widely used to control rapidly spreading, acute, and often severe infections; however, effective drugs are still not available.

The genomes of SARS-CoV-2 and SARS-CoV are approximately 80 % identical, while the genomes of SARS-CoV-2 and MERS-CoV are approximately 50 % identical. This indicates that there may be common mechanisms of coronavirus pathogenesis and, therefore, potential therapeutic targets for each virus may be the same. The enzymes and effector proteins that make up the replication-transcription complex (RTC) of coronaviruses are encoded by a large replicase gene. These enzymes and effector proteins represent promising targets for potential therapeutic drugs. The enzyme targets include papain- and 3C-like cysteine proteinases that process two large viral polyproteins, RNA-dependent RNA polymerase, RNA helicase, viral genome-modifying enzymes, and enzymes with 3'-5' exoribonuclease or uridylate-specif ic endonuclease activity.

Currently, there are many studies investigating the complex molecular mechanisms involved in the assembly and function of the RTC. This review will encompass current, modern studies on the properties and complexes of individual non-structural subunits of the RTC, the structures of individual coronavirus RTC subunits, domain organization and functions of subunits, protein-protein interactions, properties and architectures of subunit complexes, the effect of mutations, and the identif ication of mutations affecting the viability of the virus in cell culture.
The problem of the existence of an additional (independent on the energy) first integral, of a geodesic (or magnetic geodesic) flow, which is polynomial in momenta is studied. The relation of this problem to the existence of nontrivial solutions of stationary dispersionless limits of two-dimensional soliton equations is demonstrated. The nonexistence of an additional quadratic first integral is established for certain classes of magnetic geodesic flows.
Metal-semiconductor Janus-like nanoparticles with the composition tantalum silicide-silicon (TaSi₂/Si) were synthesized for the first time by means of an evaporation method utilizing a high-power electron beam. The composition of the synthesized particles were characterized using high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), selective area electron diffraction (SAED), and energy dispersive X-ray fluorescence (EDX) analysis. The system is compared to previously synthesized core-shell type particles in order to show possible differences responsible for the Janus-like structure forming instead of a core-shell architecture. It is proposed that the production of Janus-like as opposed to core-shell or monophase particles occurs due to the ability of Ta and Si to form compounds and the relative content of Ta and Si atoms in the produced vapour. Based on the results, a potential mechanism of formation for the TaSi₂/Si nanoparticles is discussed.
Helicons (circularly-polarized electromagnetic waves) propagate in a plasma with density exceeded cut-off for its frequency, and provide effective energy delivery to plasma. Accordingly, helicon discharge is one of the most suitable way for production of high-density low-temperature plasma. Helicon plasma sources, operating in the MHz frequency range and respectively low magnetic fields (0.01-0.1 T), capable to create plasma with density up to 1013 cm−3. At the same time, next generation of linear plasma facilities for both for PMI studies and fusion applications requires production of plasma with density above this limit. Theoretical studies predict that such increasing of density can be achieved by application of powerful microwave sources of GHz range frequency.

The aim of the presented experiments is experimental verification of theoretical predictions and search of conditions for effective delivery of electromagnetic power to plasma towards development of stationary source of dense plasma for linear facilities. Interaction of 2.45 GHz electromagnetic radiation with low-temperature plasma column, confined in a strong magnetic field, was studied on the GOL-3 facility. Plasma was created by external source (arc plasma gun) placed on the edge of the facility. Microwave power is transferred from moderate power (1.4 kW) magnetron source to o-ring antenna, separated from plasma column by quartz tube. Coupling of antenna with plasma (reflected-to-direct wave ratio) are measured for various magnetic fields in the facility.

First results of the measurements are presented in the paper.
The article reviews different perspectives concerning the status, origin and functions of double translations in European cultural space throughout the period. The term double translation here refers to the translation of one word with two (rarely more) lexemes connected with a conjunction or another linking word. This technique was universal across medieval translation schools, whatever their geographic origin. However, only particular schools or individual translators have been studied in terms of this technique so far, so the author aims to summarize the findings, delineate some controversial issues in the domain under consideration and place the findings in a common perspective. The controversial issues comprise (but are not limited by) the causes of their emergence in translated texts (from almost accidental fixation of the translator’s hesitation to the conscious decision to apply two different methods of translation based on specific philosophy of language). Another widely discussed question is the status of the words in such a pair – whether they were regarded as synonyms or had another status. One more question that causes discussion is their functions in the text, namely whether they were a rhetorical device or a certain means of semantic differentiation. The author of the article supposes that double translation should be considered dynamically and such chronological consideration makes it possible to argue that double translations first appeared to convey the whole range of meanings of a certain word enabling the reader to make their own choice concerning the exact meaning of the word in each particular context. As for the philosophical or theological background of the technique (be it language philosophy of St. Augustine or the theory of images developed by Pseudo-Dionysius the Areopagite) sometimes assumed to have been intentionally realized by medieval translators, it is hard to verify such claims as the utterances (Prefaces) of the medieval translators themselves hardly mention (with the possible exception of Praefatio Brixiana) either the technique or its presumed theological grounds. Moreover, word pairs (hendyadis) had been used as a rhetorical device both in the literary tradition and the national epic poetry of many European countries. This rhetorical device was widely used for emphasis, so when double translation actually lost its semantic function, it was retained by languages as set phrases or a purely stylistic device.
A set of experimental results concerning the accumulation of inelastic strain in the VT6 titanium alloy is presented. The considered tests include cyclic stress-controlled loading with monotonically increasing stress amplitude and constant mean stress. The focus of the study is on the accurate phenomenological modelling of the complex material behaviour. Four different material models are employed to capture the phenomena of ratcheting and nonlinear kinematic hardening. Two models are of the Armstrong-Frederick type and the remaining two models are of the Ohno-Wang type. Since all the considered models contain a big number of material parameters, a sophisticated nested procedure is used for the parameter identification; the obtained material parameters are validated by additional experiments. It is shown that all the models yield nearly the same accuracy; the limitations of the phenomenological approach are highlighted and discussed.
