The authors present the results of 2021 field archaeological research carried out in at the Komudwanу Terminal Paleolithic site located in the estuarine part of the Manya river (Oktyabrsky District of the Khanty-Mansi Autonomous Okrug). The research was directed to study the geomorphological and geological features in the vicinity of the site, to specify the stratigraphic position of the cultural layers and to get new archaeological materials.

The terrace and cape sections of the site as well as the adjacent areas were examined, surface finds were searched, several excavation trenches and a test pit were established (total area 10 m2). High water level in the river Manya did not allow explorations of the floodplain area of the site.

The detailed stratigraphy description of the terrace and cape sections has been made, which testify to simultaneity of the uncovered archaeological materials; the geomorphological and geological features of the site area and the estuarine part of the Manya river has been clarified; the derived data testify the presence of humans 15-14 cal kyr BP. In the excavation trench on the terrace-like area, the upper bone-bearing level (layer 4) was excavated over the area of 8 sq. m, the medial bone-bearing level (layer 5) was discovered for the first time; 29 bones, of which all definable bones were those of mammoth, and 10 lithic artifacts were found in the upper bone-bearing level. Stone assemblage includes a spall with utilization retouch, flakes, shatters and a chip. Komudvany is the northernmost Terminal Paleolithic site on the West Siberian Plain.

A search for the decay $ K_{\mathrm{S}}^0\to {\mu^{+}}{\mu^{-}} $ is performed, based on a data sample of 1.0 fb −1 of pp collisions at $ \sqrt{s}=7\;\mathrm{TeV} $ collected by the LHCb experiment at the Large Hadron Collider.

The observed number of candidates is consistent with the background-only hypothesis, yielding an upper limit of $ \mathcal{B}\left( {K_{\mathrm{S}}^0\to {\mu^{+}}{\mu^{-}}} \right) $ < 11(9) × 10 −9 at 95 (90)% confidence level.

This limit is a factor of thirty below the previous measurement.
According to microelectronic production leaders the lithography based on the free electron laser (FEL) could become the main technology for the elements mass production with scale to 5 nm in the nearest future. One of the main problem is the absence of the working FEL with required parameters. The feasibility study of those FEL based on superconducting energy-recovery linac (ERL) was made in Budker INP. The ERL average current is limited by longitudinal and transverse instabilities, caused by interaction between electron beam and its induced fields in the superconducting cavities. The estimations of the threshold currents and ERL parameters were made.
The first observation of the B¯0→J/ψK+K− decay is presented with a data sample corresponding to an integrated luminosity of 1.0 fb−1 of pp collisions at a center-of-mass energy of 7 TeV collected with the LHCb detector. The branching fraction is measured to be B(B¯0→J/ψK+K−)=(2.53±0.31±0.19)×10−6, where the first uncertainty is statistical and the second is systematic. An amplitude analysis of the final state in the B¯0→J/ψK+K− decay is performed to separate resonant and nonresonant contributions in the K+K− spectrum. Evidence of the a0(980) resonance is reported with statistical significance of 3.9 standard deviations. The corresponding product branching fraction is measured to be B(B¯0→J/ψa0(980),a0(980)→K+K−)=(4.70±3.31±0.72)×10−7, yielding an upper limit of B(B¯0→J/ψa0(980),a0(980)→K+K−)<9.0×10−7 at 90% confidence level. No evidence of the resonant decay B¯0→J/ψϕ is found, and an upper limit on its branching fraction is set to be B(B¯0→J/ψϕ)<1.9×10−7 at 90% confidence level.9 MoreReceived 27 August 2013DOI:https://doi.org/10.1103/PhysRevD.88.072005This article is available under the terms of the Creative Commons Attribution 3.0 License.

In rodent female mammals, there are two forms of X-inactivation – imprinted and random which take place in extraembryonic and embryonic tissues, respectively. The inactive X-chromosome during random X-inactivation was shown to contain two types of facultative heterochromatin that alternate and do not overlap. However, chromatin structure of the inactive X-chromosome during imprinted X-inactivation, especially at early stages, is still not well understood.

In this work, we studied chromatin modifications associated with the inactive X-chromosome at different stages of imprinted X-inactivation in a rodent, Microtus levis.

It has been found that imprinted X-inactivation in vole occurs in a species-specific manner in two steps. The inactive X-chromosome at early stages of imprinted X-inactivation is characterized by accumulation of H3K9me3, HP1, H4K20me3, and uH2A, resembling to some extent the pattern of repressive chromatin modifications of meiotic sex chromatin. Later, the inactive X-chromosome recruits trimethylated H3K27 and acquires the two types of heterochromatin associated with random X-inactivation.
A novel practical method for electronic triggering of essentially different pulsed regimes in fiber cavity lasers is introduced. The method relies on electronic control of complementary transmission characteristics of a fiber-coupled LiNbO3 waveguide electro-optic switch (WEOS) which plays the role of the variable output coupler in a fiber cavity. The method was studied using a testbed laser configuration comprised of a semiconductor optical amplifier (SOA) and an all-fiber cavity. Modulation of the WEOS-based output coupling in the fast gain recovery configuration allowed not only high-quality mode locking and harmonic mode-locking at certain pulse repetition rates determined by the cavity round trip time, but it also allowed nanosecond pulsed output of the same quality to be yielded by cavity dumping at widely and continuously tunable repetition rate (ranging from kHz to MHz). Thus, WEOS-based electronically variable output coupling allows uniquely high flexibility for lasing regimes and characteristics within a single all-fiber cavity configuration.

A Moutard type transformation for matrix generalized analytic functions is derived. Relations between Moutard type transforms and gauge transformations are demonstrated.
Investigation of high frequency external perturbation effect on flow inside T-shape microchannel was examined. In-phase pulsations of different frequencies were added to both inlets of the T-shaped microchannel to study mixing by means of Micro Laser Induced Fluorescence (μLIF) technique. For all flow regimes studied, mixing enhancement was obtained. Significant enhancement can be achieved at the beginning of the outlet channel operating in steady asymmetric regime (Re=186) by forcing at certain frequency ranges (f = 500Hz, f = 800Hz). Mixing suppression was also observed for two flow regimes (Re = 400, f = 1000Hz) and (Re = 120, f = 700Hz).

The proposed approach is tested on the real innovative project with venture financing in the pharmaceutical industry.

The paper concludes that the value of the compound real option increases the overall value of the innovative project due to the factor of staged investment and a possibility to stop financing. The efficiency of using real options method when applied to the evaluation of the effectiveness of innovative projects by a venture investor is shown
We study the system of equations which describes barotropic (isentropic) flows of viscous compressible multi-fluids (mixtures of fluids). We study the relations between pressure, densities, concentrations, viscosities and other parameters of the flow and of the medium.
Here, we report the complete genome sequences of two Newcastle disease virus (NDV) isolates, Adygea/duck/12/2008, from a wild duck in Russia, and Altai/pigeon/777/2010, from a pigeon in Russia. Based on comparative sequence analysis of the F gene, these strains were classified as NDV class II, genotypes VIId and VIb/2, respectively.
using the full Belle data sample of 772 x 10^6 BBbar pairs collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The analysis uses hadronic reconstruction of the tag-side B meson and purely leptonic tau decays.

We report a measurement of the branching fraction ratios R(D(*)) of Bbar -> D(*) tau- nubar_tau relative to Bbar -> D()* l- nubar_l (where l = e or mu)

The measured values are R(D)= 0.375 +- 0.064(stat.) +- 0.026(syst.) and R(D*) = 0.293 +- 0.038(stat.) +- 0.015(syst.). The results are consistent with earlier measurements and do not show a significant deviation from the standard model prediction.
The study of free supersonic jets showed that the condensation process leads to the Van-der-Waals clusters formation. Supersonic flows clustering leads to a change of the first jet dimensions and to the formation of a secondary structure ("trace"). When the jet is ionized by an electron beam, this structure has a weakly fading glow outside the ionization region. The authors of this work explore the processes leading to the formation of this glow. The condensation influence on the background gas penetration into the jet, the energy exchange effect between jet particles and background particles, and particle lifetime in the "trace's" glow process are studied.
The problem of the formation of the Russian model of management is interdisciplinary; it requires a whole range of approaches developed in various branches of knowledge. The philosophy of management is intended to serve as a common conceptual and interdisciplinary foundation that provides a holistic perception and understanding of management. It allows to view this phenomenon as a unity of science, practice and art. Among the axiological problems of the philosophy of management, the problems of organizational culture take center stage.

To understand this phenomenon, we need a set of basic ideas about human nature, the meaning and form of activity, social reality, relationship with the external environment, the nature of human relations, etc. This notion of organizational culture can only be formed with a philosophical approach that allows implementing the integrating function of philosophy.

The paper shows that the values of paternalism and security will be the near future priorities defining the development of Russian organizational culture.
Chromatin immunoprecipitation followed by sequencing, i.e. ChIP-Seq, is a widely used experimental technology for the identification of functional protein-DNA interactions. Nowadays, such databases as ENCODE, GTRD, ChIP-Atlas and ReMap systematically collect and annotate a large number of ChIP-Seq datasets. Comprehensive control of dataset quality is currently indispensable to select the most reliable data for further analysis.

In addition to existing quality control metrics, we have developed two novel metrics that allow to control false positives and false negatives in ChIP-Seq datasets. For this purpose, we have adapted well-known population size estimate for determination of unknown number of genuine transcription factor binding regions. Determination of the proposed metrics was based on overlapping distinct binding sites derived from processing one ChIP-Seq experiment by different peak callers.

Moreover, the metrics also can be useful for assessing quality of datasets obtained from processing distinct ChIP-Seq experiments by a given peak caller. We also have shown that these metrics appear to be useful not only for dataset selection but also for comparison of peak callers and identification of site motifs based on ChIP-Seq datasets. The developed algorithm for determination of the false positive control metric and false negative control metric for ChIP-Seq datasets was implemented as a plugin for a BioUML platform.
A broad peaking structure is observed in the dimuon spectrum of $B^+ \to K^+ \mu^+\mu^-$ decays in the kinematic region where the kaon has a low recoil against the dimuon system.

The structure is consistent with interference between the $B^+ \to K^+ \mu^+\mu^-$ decay and a resonance and has a statistical significance exceeding six standard deviations. The mean and width of the resonance are measured to be $4191^{+9}_{-8}\mathrm{\,Me\kern -0.1em V/}c^2$ and $65^{+22}_{-16}\mathrm{\,Me\kern -0.1em V/}c^2$, respectively, where the uncertainties include statistical and systematic contributions.

These measurements are compatible with the properties of the $\psi(4160)$ meson. First observations of both the decay $B^+ \to \psi(4160) K^+$ and the subsequent decay $\psi(4160) \to \mu^+\mu^-$ are reported. The resonant decay and the interference contribution make up 20\,% of the yield in the low recoil region, which is larger than theoretical estimates.
Gravitational instability in classical Jeans theory, General Relativity, and modified gravity is considered. The background density increase leads to a faster growth of perturbations in comparison with the standard theory. The transition to the Newtonian gauge in the case of coordinate dependent background metric functions is studied. For modified gravity a new high frequency stable solution is found.
Heat pipes are a good solution for temperature stabilization, for example, of microelectronics, because these kinds of systems are without any moving parts.

Experimental research of the effect of operating parameters on the heat transfer in a cylindrical heat pipe has been conducted. The effect of the working fluid properties and the porous layer thickness on the heat flux and temperature difference in the heat pipe has been investigated. The temperature field of the heat pipe has been investigated using the IR-camera and K-type thermocouples. The data obtained by IR-camera and K-type thermocouples have been compared.

It is demonstrated the power transferred from the evaporator to the condenser is a linear function of the temperature difference between them.
Since December 2010, the CMD-3 detector has collected data at the electronpositron collider VEPP-2000. The sample of the accumulated data corresponds to about 60 pb−1 of integrated luminosity in the c.m. energy from 0.32 up to 2 GeV. Preliminary results of the analysis of various processes e+e− annihilation to hadrons are presented. It is shown the processes with multihadron events have several intermediate states which must be taken into account to correctly describe the angular and invariant mass distributions as well as cross section dependence versus energy.
We report new measurements of the cross sections for the production of D Dbar final states at the psi(3770) resonance. Our data sample consists of an integrated luminosity of 2.93/fb of e+e- annihilation data produced by the BEPCII collider and collected and analyzed with the BESIII detector. We exclusively reconstruct three D0 and six D+ hadronic decay modes and use the ratio of the yield of fully reconstructed D Dbar events ("double tags") to the yield of all reconstructed D or Dbar mesons ("single tags") to determine the number of D0 D0bar and D+D- events, benefiting from the cancellation of many systematic uncertainties. Combining these yields with an independent determination of the integrated luminosity of the data sample, we find the cross sections to be \sigma(e+e- --> D0 D0bar)=(3.615 +- 0.010 +- 0.038) nb and \sigma(e+e- --> D+D-)=(2.830 +- 0.011 +- 0.026) nb, where the uncertainties are statistical and systematic, respectively.
At present new SuperKEKB collider is under commissioning at KEK (Japan) while the Belle II detector for experiments at this collider is at the final stage of the construction.

The luminosity of this collider will exceed the previous one by about 40 times, amounting to 8 × 1035cm−2s−1.

The electromagnetic calorimeter is a very important component of the BELLE II detector. This calorimeter is described in this report.

Optical rogue waves emerge in nonlinear optical systems with extremely large amplitudes, and leave without a trace. In this work, we reveal the emergence of optical polarization rogue waves in supercontinuum generation from a zero-dispersion fiber, pumped by a dissipative soliton laser. Flat spectral broadening is achieved by modulation instability, followed by cascaded four-wave-mixing. In this process, we identify the emergence of optical polarization rogue waves, based on the probability density function of the relative distance among polarization states. Experimental results show that optical polarization rogue waves originate from vector multi-wave-mixing. Besides, we observe double peaks, and even triple peaks in the histogram of the state of polarization. This is a new and intriguing property, never observed so far in optical rogue waves, for example those emerging in the statistics of pulse intensities. Our polarization domain statistical analysis provides a new insight into the still debated topic of the mechanism for rogue wave generation in optical supercontinuum.
A report on the International Scientific Conference 'JAPAN XXI NOVA: Era and Century' held at the Faculty of Asian and African Studies of St. Petersburg State University on 9–10 October 2020.

Brief descriptions of the presented papers are given.
Thawing of subsea permafrost can impact offshore infrastructure, affect coastal erosion, and release permafrost organic matter. Thawing is usually modeled as the result of heat transfer, although salt diffusion may play an important role in marine settings.

To better quantify nearshore subsea permafrost thawing, we applied the CryoGRID2 heat diffusion model and coupled it to a salt diffusion model. We simulated coastline retreat and subsea permafrost evolution as it develops through successive stages of a thawing sequence at the Bykovsky Peninsula, Siberia. Sensitivity analyses for seawater salinity were performed to compare the results for the Bykovsky Peninsula with those of typical Arctic seawater. The model outputs were compared to the IBPT depth estimated from coastline retreat and electrical resistivity surveys perpendicular to and crossing the shoreline of the Bykovsky Peninsula.

For the Bykovsky Peninsula, the modeled ice-bearing permafrost table (IBPT) for ice-rich sand and an erosion rate of 0.25 m/year was 16.7 m below the seabed 350 m offshore. The interpreted geoelectric data suggest that the IBPT dipped to 15-20 m below the seabed at 350 m offshore. Both results suggest that cold saline water forms beneath grounded ice and floating sea ice in shallow water, causing cryotic benthic temperatures. The freezing point depression produced by salt diffusion can delay or prevent ice formation in the sediment and enhance the IBPT degradation rate. Therefore, salt diffusion may facilitate the release of greenhouse gasses to the atmosphere and considerably affect the design of offshore and coastal infrastructure in subsea permafrost areas.
The problems of heart failure (HF) are becoming increasingly important every year due to the increasing spread of cardiovascular diseases resulting in its development, as well as the impact of metabolic factors, obesity, drugs and endocrine dysfunctions on the myocardium. Isolation of phenotypes with preserved, mid-ranged and reduced ejection fraction in HF allows ranking the evidence base and identifying groups of patients with preferred drug intervention strategies aimed at achieving the six goals of treating HF patients and, above all, reducing mortality.

The results of recent studies have significantly expanded the list of tools for management of HF with reduced ejection fraction (EF), presented today, according to John J. V. McMurray, by five pillars: angiotensin-converting enzyme inhibitors or angiotensin-II receptor blockers, angiotensin receptor antagonist/neprilysin inhibitor, beta-blockers, mineralocorticoid receptor antagonists, sodium-glucose cotransporter 2 (SGLT2).

On the other hand, the exceptional heterogeneity of patients with HF with preserved and mid-range EF and a prevailing opinion on the need for a unified therapy for patients with HF with mid-range and reduced EF, along with the absence of proven prognosis-modifying drugs, require the identifying phenotypic clusters of patients for targeted selection of a treatment strategy. This was the subject of interest in this literature review.
The dynamics of high-energy Raman solitons in graded-index multimode fibers is both numerically and experimentally investigated.

The propagation of high-power pulses produces nonlinear losses, that quench up to 80% of the fiber transmission.

In such a regime, several solitons arising from the fission of ultra-short femtosecond pulses manifest unique features: pulse width, Raman self-frequency shift and soliton order remain nearly constant over a broad range of energies.
ODIP can serve as a tool for enhancing Nuclear Magnetic Resonance (NMR) signals of 2H nuclei, being important probes of molecular structure and dynamics.

To produce ODIP, in the first step, the D2 gas is brought to thermal equilibrium at low temperature, here 30 K, so that the ortho-component, corresponding to the total spin of the 2H nuclei equal to 0 and 2, is enriched, here to 92%. In the second step, the orthodeuterium molecule is attached to a substrate molecule using a suitable hydrogenation catalyst such that the symmetry of the two 2H nuclei is broken. As a result, the non-thermal spin order of orthodeuterium is converted into enhancement of observable NMR signals. In this work, we perform a theoretical study of ODIP and calculate the shape of ODIP spectra and their dependence on the magnetization flip angle. These results are compared with experiments performed for a number of substrates; good agreement between experimental and calculated ODIP spectra is found. We also discuss the performance of NMR techniques for converting anti-phase ODIP spectral patterns into in-phase patterns, which are more suitable for signal detection and for transferring ODIP to heteronuclei, here to 13C spins.

Experimental procedures reported here allowed us to reach signal enhancement factors of more than 1000 for 2H nuclei in the liquid phase. These results are useful for extending the scope of spin hyperpolarization to the widely used 2H nuclei.
