Two experiments, CMD-3 and SND, collected over 100 pb−1 in total taking data in 2011-2013 at the VEPP-2000 electron-positron collider. The data sample covers the whole available c.m. energy range from 0.32 GeV to 2.0 GeV. An upgrade of VEPP-2000 started in the second half of 2013, aimed at the luminosity increase up to 10 times at 2.0 GeV. Data taking is expected to resumed in 2015. The current results of analysis of the collected data for various modes of e+ e− → hadrons are discussed.
The article is devoted to the study of the escape to the cities as a tactic of the struggle of the "deprived" for the restoration of rights.Based on the analysis of petitions for the restoration of the voting rights of the "deprived" in the Iskitim and Maslyaninsky districts of Western Siberia, the behavioral practices of the "deprived" in the process of forced migration to cities are reconstructed.The discriminatory policy of the Soviet leadership in the Siberian countryside in the late 1920s and the first half of the 1930s led to the outflow of rural population to large cities, as well as to the destruction of social structure of Siberia with peasants being the dominant group in the population.Organized recruitment did not produce significant results due to a number of reasons as opposed to spontaneous migration.At the same time, forced migration was considered by the "deprived" as a way to avoid the economic difficulties associated with running their own economy, as well as to escape from further repression (confiscation of property and expulsion).The "deprived" used various strategies wen specifying cities in their petitions, but in most cases the very fact that they worked at a factory in the city was considered by the discriminated as proof of loyalty to the Soviet government.Besides, the children of the "deprived" used the fact of moving to the city as proof of a break with their family.The retreat to the cities was one of the tactics of the struggle of the "deprived" for the restoration of their rights.The evaluation of the effectiveness of this tactic showed that the "deprived" achieved their goal in most cases only when a significant evidence base was attached to the petitions.
Human placenta is an organ which protects, feeds, and regulates the grooving of the embryo. Therefore, identification and characterization of placental components including proteins and their multi-protein complexes is an important step to understanding the placenta function.

We have obtained and analyzed for the first time an extremely stable multi-protein complex (SPC, ∼1000 kDa) from the soluble fraction of three human placentas. By gel filtration on Sepharose-4B, the SPC was well separated from other proteins of the placenta extract. Light scattering measurements and gel filtration showed that the SPC is stable in the presence of NaCl, MgCl2, acetonitrile, guanidinium chloride, and Triton in high concentrations, but dissociates efficiently in the presence of 8 M urea, 50 mM EDTA, and 0.5 M NaCl. According to SDS-PAGE and MALDI mass spectrometry data, this complex contains many major glycosylated proteins with low and moderate molecular masses (MMs) 4–14 kDa and several moderately abundant (79.3, 68.5, 52.8, and 27.2 kDa) as well as minor proteins with higher MMs. The SPC treatment with dithiothreitol led to a disappearance of some protein bands and revealed proteins with lower MMs.

The SPCs from three placentas efficiently hydrolyzed plasmid supercoiled DNA with comparable rates and possess at least two DNA-binding sites with different affinities for a 12-mer oligonucleotide. Progress in study of placental protein complexes can promote understanding of their biological functions.
The characteristics of burning of substandard liquid hydrocarbons in a direct-flow evaporative burner with controlled forced jet feeding of superheated steam are studied by the example of waste transmission automobile oil. The influence of the steam regime parameters on the temperature distribution in the flame, the thermal power and the composition of the combustion products is determined.

The regimes providing simultaneously a low concentration of CO and NOx and a high power of heat release have been found.
The purpose of the research is to evaluate the effect of albendazole as part of the supramolecular complex with disodium salt of glycyrrhizic acid obtained by solid-phase mechanical treatment.

Materials and methods. The anthelmintic activity of the complex and its effect on the host organism was assessed on hamsters infected with Opisthorchis felineus by single and 7-fold administration at 45 days after infection. After 21 days, we counted the number of helminthes in the liver, and conducted a morphometric analysis of the liver and spleen, and detected biochemically the activity of alanine aminotransferase and aspartate aminotransferase in the animals' blood serum.

Results and discussion. The number of O. felineus significantly decreased after 7-fold, but not a single, administration of albendazole (ABZ) and ABZ-Na 2 GA complex (1 : 10). The administrated substances had no effect on the weight gain of the animals and the daily consumption of the pellets. At the same time, ABZ only as part of the complex normalized the weight of the liver and spleen in hamsters infected with O. felineus and reduced the alanine aminotransferase activity. Consequently, a longer administration of ABZ as part of the complex with disodium glycyrrhizinate has not only a pronounced anthelmintic effect, but also improves some of the physiological parameters of hamsters to a greater extent than a pure substance.
We reveal that synthetic photonic lattices based on coupled fiber loops can realize deep neural networks for coherent manipulation of optical pulse trains, which could lead to advances in communications and real-time data analysis. We show the platform feasibility for an essential task of telecommunication signal equalization. We also demonstrated that utilizing all-optical Kerr nonlinearity within the system may open a path to complex signal manipulation.
Sakha--an area connecting South and Northeast Siberia--is significant for understanding the history of peopling of Northeast Eurasia and the Americas. Previous studies have shown a genetic contiguity between Siberia and East Asia and the key role of South Siberia in the colonization of Siberia.

We report the results of a high-resolution phylogenetic analysis of 701 mtDNAs and 318 Y chromosomes from five native populations of Sakha (Yakuts, Evenks, Evens, Yukaghirs and Dolgans) and of the analysis of more than 500,000 autosomal SNPs of 758 individuals from 55 populations, including 40 previously unpublished samples from Siberia.

Phylogenetically terminal clades of East Asian mtDNA haplogroups C and D and Y-chromosome haplogroups N1c, N1b and C3, constituting the core of the gene pool of the native populations from Sakha, connect Sakha and South Siberia. Analysis of autosomal SNP data confirms the genetic continuity between Sakha and South Siberia. Maternal lineages D5a2a2, C4a1c, C4a2, C5b1b and the Yakut-specific STR sub-clade of Y-chromosome haplogroup N1c can be linked to a migration of Yakut ancestors, while the paternal lineage C3c was most likely carried to Sakha by the expansion of the Tungusic people. MtDNA haplogroups Z1a1b and Z1a3, present in Yukaghirs, Evens and Dolgans, show traces of different and probably more ancient migration(s). Analysis of both haploid loci and autosomal SNP data revealed only minor genetic components shared between Sakha and the extreme Northeast Siberia. Although the major part of West Eurasian maternal and paternal lineages in Sakha could originate from recent admixture with East Europeans, mtDNA haplogroups H8, H20a and HV1a1a, as well as Y-chromosome haplogroup J, more probably reflect an ancient gene flow from West Eurasia through Central Asia and South Siberia.Our high-resolution phylogenetic dissection of mtDNA and Y-chromosome haplogroups as well as analysis of autosomal SNP data suggests that Sakha was colonized by repeated expansions from South Siberia with minor gene flow from the Lower Amur/Southern Okhotsk region and/or Kamchatka. The minor West Eurasian component in Sakha attests to both recent and ongoing admixture with East Europeans and an ancient gene flow from West Eurasia.
On the stage of YSO O-I the whole of factors: chemical composition of gas and solids, chemical catalytic reactions, the disc self-gravitation, the increased ratio of solids to gas surface density, adiabatic gas cooling provides favorable conditions for gravitational instabilities development.

We simulated 3D dynamics of gas and dust under self-consistent gravitational field and reproduced the formation and evolution of the disc around the protostar.

We found that for stars of Solar mass there are regimes when the disc of variable mass is unstable for the development of fast gravitational instabilities.
Fasting is often used for obesity correction but the 'refeeding syndrome' limits its efficiency, and molecular mechanisms underlying metabolic response to different food availability are under investigation. Sex was shown to affect hormonal and metabolic reactions to fasting/refeeding.

The aim of this study was to evaluate hormonal and transcriptional responses to fasting and refeeding in male and female C57Bl/6J mice. Sex asymmetry was observed both at the hormonal and transcriptional levels. Fasting (24 h) induced increase in hepatic Fgf21 gene expression, which was associated with elevation of plasma FGF21 and adiponectin levels, and the upregulation of expression of hepatic (Pparα, Cpt1α) and muscle (Cpt1β, Ucp3) genes involved in fatty acid oxidation. These changes were more pronounced in females. Refeeding (6 h) evoked hyperinsulinemia and increased hepatic expression of gene related to lipogenesis (Fasn) only in males and hyperleptinemia and increase in Fgf21 gene expression in muscles and adipose tissues only in females.

The results suggest that in mice, one of the molecular mechanisms underlying sex asymmetry in hepatic Pparα, Cpt1α, muscle Cpt1β, and Ucp3 expression during fasting is hepatic Fgf21 expression, and the reason for sex asymmetry in hepatic Fasn expression during refeeding is male-specific hyperinsulinemia.
The results are in good agreement with the previous works of different authors.

The structure of the deflagration burning front in Type Ia supernovae is considered. The parameters of the flame are obtained: its normal velocity and thickness. The problem of pulsation instability of the flame, subject to plane perturbations, is studied. First, with an artificial system with switched-off hydrodynamics the possibility of secondary reactions stabilizing the front is shown. Secondly, taking account of hydrodynamics and using a realistic equation of state (EOS) and thermal conduction, we can obtain pulsations when the Zeldovich number is artificially increased. The critical Zeldovich numbers are presented.

These results show the stability of the flame in a Type Ia supernova against pulsations, because its effective Zeldovich number is small.
We report measurements of the branching fractions and direct CP asymmetries (A_{CP}) for B->K pi, pi pi and KK decays (but not pi^0 pi^0) based on the final data sample of 772x10^6 B B-bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^+ e^- collider. We set a 90% confidence-level upper limit for K^+- K^-+ at 2.0x10^{-7}; all other decays are observed with branching fractions ranging from 10^{-6} to 10^{-5}. In the $B^0/B^0-bar -> K^+-\pi^-+ mode, we confirm Belle's previously reported large A_{CP} with a value of -0.069 +- 0.014 +- 0.007 and a significance of 4.4 sigma. For all other flavor-specific modes, we find A_{CP} values consistent with zero, including A_{CP}(K^+- \pi^0) = +0.043 +- 0.024 +- 0.007 with 1.8 sigma significance. The difference of CP asymmetry between B^+- -> K^+- pi^0 and B^0/B^0-bar -> K^+-\pi^-+ is found to be Delta A_{K pi} equiv A_{CP} (K^+ pi^0) - A_{CP}(K^+ pi^-) = +0.112 +- 0.027 +- 0.007 with 4.0 sigma significance. We also calculate the ratios of partial widths for the B-> K pi decays. Using our results, we test the validity of the sum rule A_{CP}(K^+ pi^-) + A_{CP}(K^0\pi^+) x Gamma(K^0\pi^+)/Gamma(K^+ pi^-)} - A_{CP}(K^+ pi^0)x 2Gamma(K^+ pi^0)/Gamma(K^+ pi^-) - A_{CP}(K^0 pi^0)x 2Gamma(K^0 pi^0)/Gamma(K^+ pi^-) = 0 and obtain a sum of -0.270 +- 0.132 +- 0.060 with 1.9 sigma significance.
Hoeffding-type exponential inequalities are obtained for the distribution tails of canonical von Mises' statistics of arbitrary order based on samples from a stationary sequence of random variables satisfying the {\varphi}-mixing condition. The present paper weakens the restrictions on the coefficient {\varphi}() which are contained in the paper "Exponential inequalities for the distributions of canonical U- and V-statistics of dependent observations" by Borisov and Volodko (2009). At the same time, we correct the corresponding proof in this paper.
Using the Helmholtz decomposition of the vector field of folding fluxes in a two-dimensional space of collective variables, a potential of the driving force for protein folding is introduced. The potential has two components. One component is responsible for the source and sink of the folding flows, which represent, respectively, the unfolded states and the native state of the protein, and the other, which accounts for the flow vorticity inherently generated at the periphery of the flow field, is responsible for the canalization of the flow between the source and sink.

The theoretical consideration is illustrated by calculations for a model $eta$-hairpin protein.
The formation of planetesimals and large bodies in circumstellar discs can be referred to the stage of massive unstable disc emerging due to the gravitational collapse in the molecular cloud. We have simulated the dynamics of gas and boulder clumps in such systems. The features of instability development in massive disc is discussed. Unlike medium-massive discs the massive disc can provide conditions for simultaneous formation of several clumps as a result of overdensity ring fragmentation. We found regimes where 3, 2 or 1 overdensity ring appear in the disc and then fragment into clumps collecting about a half of the disc mass.
Archaeological science has intensively developed in the last few decades. The methodology is being improved, the number of investigated objects is increasing, and archaeological material is accumulating. One of the most important aspects of scientific activity is the integration of the results of work into the scientific community.

On March 16–19, 2020, a scientific seminar named “The complexes with flat-bottomed ceramics in the Neolithic of the Urals and Western Siberia: typology, technology, chronology, genesis” was held in Yekaterinburg. More than 50 leading specialists came from the Urals, Western Siberia, Germany and Japan. The set of reports were presented, each presentation was followed by a discussion. The participants had an opportunity to examine the collections of the archaeological sites with flat-bottomed pottery.

It has been confirmed that flat-bottomed pottery appeared in Western Siberia and the Urals in the 7th millennium BC. The earliest complexes were discovered in the Baraba forest-steppe and in the Taiga regions in the North of Western Siberia. In local areas, different types of dishes are distinguished, having both similar features and differences. Discussions remain the genesis of morphologically different vessels. Problems of the attitude of complexes of flat-bottomed ceramics to the early and late stages of the Neolithic, the paths and variants of neolithization processes, the spread of ceramic production in a wide area of the region. The current problem of the ratio of Upper Paleolithic, Mesolithic and Early Neolithic formations in the region appears to be relevant. As well as the time of the invention of pottery by man, the fact which radically changed his economy and culture, as well as the physiology of man himself.
Resonant structures in B^{0}→ψ^{'}π^{-}K^{+} decays are analyzed by performing a four-dimensional fit of the decay amplitude, using pp collision data corresponding to 3 fb^{-1} collected with the LHCb detector. The data cannot be described with K^{+}π^{-} resonances alone, which is confirmed with a model-independent approach. A highly significant Z(4430)^{-}→ψ^{'}π^{-} component is required, thus confirming the existence of this state. The observed evolution of the Z(4430)^{-} amplitude with the ψ^{'}π^{-} mass establishes the resonant nature of this particle. The mass and width measurements are substantially improved. The spin parity is determined unambiguously to be 1^{+}.
A numerical simulation of a supersonic (M∞ = 7) flow around a cylinder with a front gas-permeable porous insert at a zero angle of attack was carried out using three-dimensional skeleton models of a highly porous cellular material made of non-intersecting hard spheres with a regular and chaotic arrangement of pores.

A comparative analysis of these skeleton models with different spatial arrangement and pore size showed a weak influence of the structure of skeleton models on the resistance of a cylinder with a front gas-permeable insert.

The computed data of the drag coefficient are compared with the results of tube experiments.
Die milde Thermolyse der Lewis‐Base‐stabilisierten Phosphanylboran‐Monomere R 1 R 2 P‐BH 2 ⋅NMe 3 (R 1 ,R 2 =H, Ph oder t Bu/H) von Raumtemperatur bis 100 °C ist eine bequeme Synthesemethode für Oligo‐ und Poly(phosphanylborane) [R 1 R 2 P‐BH 2 ] n .

Die Polymerisation scheint über eine Additions‐/Kopf‐Schwanz‐Polymerisation kurzlebig, freier Phosphanylboran‐Monomere, R 1 R 2 P‐BH 2 , zu verlaufen.

Diese Methode liefert hochmolekulare Materialien, wie durch Poly( tert ‐butylphosphanylborane) veranschaulicht, die gegenwärtig auf anderen Wegen (z. B. katalytische dehydrierende Kupplung) nicht zugänglich sind.
The desorption of excited rubidium atoms off the surface of helium nanodroplets is studied in detail using femtosecond time-resolved photoion and photoelectron imaging spectroscopy in combination with quantum wave-packet simulations. The good agreement of the measured time-dependent velocity distributions with the simulation when exciting the Rb dopant atoms into the $6p$ state supports the pseudodiatomic model for the Rb-He droplet interaction, even on the level of quantum wave-packet dynamics. Time-resolved photoelectron spectra reveal the partitioning of excitation energy into the dopant and the droplet degrees of freedom.
We study the free boundary problem for the plasma-vacuum interface in ideal compressible magnetohydrodynamics. Unlike the classical statement, when the vacuum magnetic field obeys the div-curl system of pre-Maxwell dynamics, we do not neglect the displacement current in the vacuum region and consider the Maxwell equations for electric and magnetic fields.We show that a sufficiently large vacuum electric field can make the planar interface violently unstable.We find and analyze a sufficient condition on the vacuum electric field that precludes violent instabilities.Under the assumption that this condition is satisfied at each point of the unperturbed nonplanar plasmavacuum interface, we prove the well-posedness of the linearized problem in anisotropic weighted Sobolev spaces.
Photoinduced processes with partial (exciplex) and full charge transfer in donor-acceptor systems are of interest because they are frequently used for modeling drug-protein binding.

Low field photo-CIDNP (chemically induced dynamic nuclear polarization) for these processes in dyads, including the drug, (S)- and (R)-naproxen and (S)-N-methyl pyrrolidine in solutions with strong and weak permittivity have been measured. The shapes of the experimental CIDNP field dependence with two extrema have been described using the Green function approach for the calculation of the CIDNP effects in the system without electron exchange interactions.

The dramatic influence of solvent permittivity on the field dependence of the N-methyl pyrrolidine (1)H CIDNP effects has been found. The field dependences of both (R,S)- and (S,S)-dyads in a polar medium are the curves with a single extremum in the area of the S-T+ terms intersection. Moreover, the CIDNP field dependences of the same protons measured in a low polar medium present curves with several extrema. The article discusses the possible causes of the differences between the CIDNP field dependence detected in a low-permittivity solvent with the strong Coulomb interactions and in a polar solvent.
The probe sampling of gases is extensively used in studies of high-temperature oxidation processes. This technique allows one to obtain directly information on the chemical composition of the reaction volume, however, inevitably introduces thermal and gas-dynamic perturbations into the system. In order to further numerically simulate the sampling process, the temperature profiles of the quartz probe surface in the CH4/O2/Ar flames were measured in a pressure range of 1-5 atm. The measurements were carried out by thermographic method using an IR camera, which was calibrated by direct thermocouple measurements taking into account flame shielding. The data obtained will be used as boundary conditions for computer simulation of the sampling processes, which will significantly improve the accuracy of the sampling probe methods.
B chromosomes (Bs) revealed more than a hundred years ago remain to be some of the most mysterious elements of the eukaryotic genome. Their origin and evolution, DNA composition, transcriptional activity, impact on adaptiveness, behavior in meiosis, and transfer to the next generation require intensive investigations using modern methods.

Over the past years, new experimental techniques have been applied and helped us gain a deeper insight into the nature of Bs. Here, we consider mammalian Bs, taking into account data on their DNA sequencing, transcriptional activity, positions in nuclei of somatic and meiotic cells, and impact on genome functioning. Comparative cytogenetics of Bs suggests the existence of different mechanisms of their formation and evolution.

Due to the long and complicated evolvement of Bs, the similarity of their morphology could be explained by the similar mechanisms involved in their development while the difference between Bs even of the same origin could appear due to their positioning at different stages of their evolution. A complex analysis of their DNA composition and other features is required to clarify the origin and evolutionary history of Bs in the species studied. The intraspecific diversity of Bs makes this analysis a very important element of B chromosome studies.
The stability and accuracy of compact difference schemes with artificial viscosities of the fourth divergence order are studied.

These schemes have a third order both of classical approximation on smooth solutions and weak approximation on discontinuous solutions. As a result of the stability analysis of these schemes in the linear approximation, the optimal values of their viscosity coefficients were obtained.

Test calculations are presented to demonstrate the advantages of the new compact scheme compared to the TVD and WENO schemes when calculating discontinuous solutions with shock waves.
