Purpose. We studied a rare finding of an iron sword, that was coincidentally discovered at the beginning of the 20th Century in the outskirts of Kuragino Village on the territory of Minusinsk Hollow. At present, the finding is stored in the collection of long blade weapon objects in the Minusinsk Museum of Local History. Results. The authors traced the most significant events and results achieved in the course of previous studying of archaeological findings of ancient and medieval swords on the territory of Southern Siberia and Central Asia. Definite formal signs, considerable for identification of typological affiliation, of the sword finding from the Kuragino Village are singled out. According to the formal signs, this finding is related to a particular individual type of iron swords. The item has a long, right double-edged blade and a removable guard, which is smoothly curved to sideways of the blade, and a right handle’s haft. Conclusion. Our analysis allows us to conclude that the iron sword was likely to be used by the Yenisei Kyrgyz warriors in the course of hostilities with their adversaries among the nomads, against the Old Turks and Uyghurs people, on the territory of Southern Siberia and contiguous territories of the Central Asian region during a certain historical period, including the Early Middle Ages, in particular the third quarter of the 1st millennium A. D. That historical period included inception of the Yenisei Kyrgyz state on the territory of the steppe regions of Minusinsk Hollow, which is located to the north of the West-Sayan Mountains.
The Spherical Neutral Detector (SND) is an experiment for e+e− annihilation study at low energies 0.2−2 GeV. The light quark anti−quark bound states are the main subject of study at these energies. They express themselves as resonances in the e+e− hadronic cross sections. Hadronic cross sections could be recalculated to hadronic vacuum polarization (HVP). The Standard Model predictions today are limited by HVP which is not calculable with modern QCD theory. In this talk we present the review of the hadronic cross sections measurements at SND and new measurements: e+e− → π+π−, π0γ, π+π−π0, ωπ0, K+K−η, η, KsKLπ0, π+π−π0η, ωπ0η e.t.c.
We consider a class of linear time-varying delay systems of neutral type with periodic coefficients.We obtain conditions for the exponential stability of the zero solution and establish estimates characterizing the exponential decay rate of solutions at infinity.
We demonstrate and numerically characterize a set of single-layer metasurfaces based on capacitively-coupled bent metal strips deposited on a thin polypropylene film operating as band-stop filters at 139.1 GHz. Due to a high inter-digital coupling capacitance between neighboring inclusions formed by the strips, the resonance of the metasurface becomes highly sensitive to the incidence angle of a plane wave. At the same time, a narrow-band resonance is achieved by reducing the conductor length along the vertical polarization direction of the incident wave.

We propose to use both properties for designing a sensor, which analyses the thickness of a thin slab of a known substance deposited over the structure by tracking the angle at which the minimum of transmission can be measured at a single frequency. We compare three versions of the proposed geometry by numerical calculation of the transmission coefficient depending on both the incidence angle and analyte slab’s thickness.

We select the most suitable structure for sensing.
Accompanying the discovery of an increasing number of proteins, there is the need to provide functional annotation that is both highly accurate and consistent. The Gene Ontology™ (GO) provides consistent annotation in a computer readable and usable form; hence, GO annotation (GOA) has been assigned to a large number of protein sequences based on direct experimental evidence and through inference determined by sequence homology. Here we show that this annotation can be extended and corrected for cases where protein structures are available. Specifically, using the Combinatorial Extension (CE) algorithm for structure comparison, we extend the protein annotation currently provided by GOA at the European Bioinformatics Institute (EBI) to further describe the contents of the Protein Data Bank (PDB). Specific cases of biologically interesting annotations derived by this method are given. Given that the relationship between sequence, structure, and function is complicated, we explore the impact of this relationship on assigning GOA. The effect of superfolds (folds with many functions) is considered and, by comparison to the Structural Classification of Proteins (SCOP), the individual effects of family, superfamily, and fold.

The Budker Institute of Nuclear Physics in worldwide collaboration has developed a project of a 14 MeV neutron source for fusion material studies and other applications. The projected neutron source of the plasma type is based on the gas dynamic trap (GDT), which is a special magnetic mirror system for plasma confinement.

Essential progress in plasma parameters has been achieved in recent experiments at the GDT facility in the Budker Institute, which is a hydrogen (deuterium) prototype of the source. Stable confinement of hot-ion plasmas with the relative pressure exceeding 0.5 was demonstrated. The electron temperature was increased up to 0.9 keV in the regime with additional electron cyclotron resonance heating (ECRH) of a moderate power.

These parameters are the record for axisymmetric open mirror traps. These achievements elevate the projects of a GDT-based neutron source on a higher level of competitive ability and make it possible to construct a source with parameters suitable for materials testing today. The paper presents the progress in experimental studies and numerical simulations of the mirror-based fusion neutron source and its possible applications including a fusion material test facility and a fusion-fission hybrid system.
This paper presents results of an experimental study of the effect of hydrophobic fluoropolymer coating on the multiscale characteristics of heat transfer at water boiling.

New experimental data on the dynamics of vapor bubble growth and detachment, the evolution of contact line, the nucleation site density, and heat transfer coefficient were obtained using high-speed imaging techniques, including infrared thermography and video recording from the bottom side of the transparent heater.

It was shown that using a hydrophobic fluoropolymer coating leads to heat transfer enhancement, to a decrease of the surface temperature at the onset of boiling, to an increase of nucleation site density, and to significant change in the dynamics of growth and departure of vapor bubbles and the evolution of the triple contact line.
An equilibrium problem for a two-dimensional homogeneous linear elastic body containing a thin elastic inclusion and an interfacial crack is considered. The thin inclusion is modeled within the framework of Euler-Bernoulli beam theory.

An explicit formula for the first derivative of the energy functional with respect to the crack perturbation along the interface is presented.

It is shown that the formulas for the derivative associated with translation and self-similar expansion of the crack are represented as path-independent integrals along smooth contour surrounding one or both crack tips. These path-independent integrals consist of regular and singular terms and are analogs of the well-known Eshelby-Cherepanov-Rice J-integral and Knowles-Sternberg M-integral.
In most mammalian cell lines, chromatin located at the nuclear periphery is represented by condensed heterochromatin, as evidenced by microscopy observations and DamID mapping of lamina-associated domains (LADs) enriched in dimethylated Lys9 of histone H3 (H3K9me2). However, in Kc167 cell culture, the only Drosophilla cell type where LADs have previously been mapped, they are neither H3K9me2-enriched nor overlapped with the domains of heterochromatin protein 1a (HP1a). Here, using cell type-specific DamID we mapped genome-wide LADs, HP1a and Polycomb (Pc) domains from the central brain, Repo-positive glia, Elav-positive neurons and the fat body of Drosophila third instar larvae. Strikingly, contrary to Kc167 cells of embryonic origin, in neurons and, to a lesser extent, in glia and the fat body, HP1a domains appear to overlap strongly with LADs in both the chromosome arms and pericentromeric regions. Accordingly, centromeres reside closer to the nuclear lamina in neurons than in Kc167 cells. As expected, active gene promoters are mostly not present in LADs, HP1a and Pc domains. These domains are occupied by silent or weakly expressed genes with genes residing in the HP1a-bound LADs expressed at the lowest level. In various differentiated Drosophila cell types, we discovered the existence of peripheral heterochromatin, similar to that observed in mammals. Our findings support the model that peripheral heterochromatin matures enhancing the repression of unwanted genes as cells terminally differentiate.
Usually, in situ diffraction studies of mechanochemical transformations use plastic milling jars in place of steel. This is done to reduce the absorbtion of radiation by the walls.

Using as an example the polymorphic transformation of β-glycine, we show that the transformation rate can vary significantly depending on the material of the jars. Using ex situ analysis we here compare the transformation rates in steel and common plastics such as acrylonitrile butadiene styrene, polylactic acid, and polyethylene terephthalate glycol.
It is represented in an article the history of the Turks till the second half of the 1st millennium A.D., from migration period out of Central Asian steppes to boundaries of the Chinese empire and their resettlement to the Altai Mountains, when the Old Turkic state was at its greatest height, took control the number of sedentary agriculturist oases and successfully confronted the major powers of that time - Chinese Persian and Byzantine empires.

Throughout the vast territory of the Sayan and Altai Mountains and Central Asian region there are represented all major types of funerary and memorial constructions of the Old Turks, which constitutes burial places according to the ritual of inhumation accompanied by riding horses or rams and memorial complexes in the form of vertically dug stone plates fences with vertically fixed stone steles.

Authors of the article consider designated historical period of the Old Turkic history from the perspective of interaction of the Old Turks and Kyrgyz, who resided in the territory of Minusinsk Hollow. Mutual relations between those two peoples took various forms in different times: unabashedly hostile passively feudatory, when the Yenisei Kyrgyz preferred not to show pure resistance to the Turks. However, such instability of their own position has not disturbed the Kyrgyz to expand the range of their own vassals.
Recent results on various cross sections of e+e−→hadrons obtained with the SND and CMD3 detectors at the VEPP-2000 collider in the energy range up to 2 GeV are presented.

The final states studied include e+e−→π+π−, K+K−, π+π−π0, π+π−π0π0, ηπ+π−, ωη, ηγ and others.

The measured cross sections are important since they contribute to the total hadronic cross section, muon g-2 and parameters of excited vector mesons. The nucleon-antinucleon production at threshold was also studied.
A new class of atomic interferences using ultra-narrow optical transitions are pushing quantum engineering control to a very high level of precision for a next generation of sensors and quantum gate operations. In such context, we propose a new quantum engineering approach to Ramsey-Bord\'e interferometry introducing multiple composite laser pulses with tailored pulse duration, Rabi field amplitude, frequency detuning and laser phase-step. We explore quantum metrology with hyper-Ramsey and hyper-Hahn-Ramsey clocks below the $10^-18$ level of fractional accuracy by a fine tuning control of light excitation parameters leading to spinor interferences protected against light-shift coupled to laser-probe field variation. We review cooperative composite pulse protocols to generate robust Ramsey-Bord\'e, Mach-Zehnder and double-loop atomic sensors shielded against measurement distortion related to Doppler-shifts and light-shifts coupled to pulse area errors. Fault-tolerant auto-balanced hyper-interferometers are introduced eliminating several technical laser pulse defects that can occur during the entire probing interrogation protocol. Quantum sensors with composite pulses and ultra-cold atomic sources should offer a new level of high accuracy in detection of acceleration and rotation inducing phase-shifts, a strong improvement in tests of fundamental physics with hyper-clocks while paving the way to a new conception of atomic interferometers tracking space-time gravitational waves with a very high sensitivity.
An Ag I dimer capped with labile organometallic diphosphorus ligands [Cp 2 Mo 2 (CO) 4 (η 2 ‐P 2 )] (Cp=C 5 H 5 ) acts as a highly pre‐organized molecular precursor to direct the construction of 1D or 2D, and 3D organometallic–organic hybrid coordination polymers upon reaction with ditopic pyridine‐based linkers. The formation of the supramolecular aggregates can be controlled by the stoichiometry of the organic molecules, and the mechanism is supported by DFT calculations.
The study of the L- and D-amino acid properties in proteins and peptides has attracted considerable attention in recent years, as the replacement of even one L-amino acid by its D-analogue due to aging of the body is resulted in a number of pathological conditions, including Alzheimer’s and Parkinson’s diseases. A recent trend is using short model systems to study the peculiarities of proteins with D-amino acids.

In this report, the comparison of the excited states quenching of L- and D-tryptophan (Trp) in a model donor–acceptor dyad with (R)- and (S)-ketoprofen (KP-Trp) was carried out by photochemically induced dynamic nuclear polarization (CIDNP) and fluorescence spectroscopy.

Quenching of the Trp excited states, which occurs via two mechanisms: prevailing resonance energy transfer (RET) and electron transfer (ET), indeed demonstrates some peculiarities for all three studied configurations of the dyad: (R,S)-, (S,R)-, and (S,S)-. Thus, the ET efficiency is identical for (S,R)- and (R,S)-enantiomers, while RET differs by 1.6 times. For (S,S)-, the CIDNP coefficient is almost an order of magnitude greater than for (R,S)- and (S,R)-. To understand the source of this difference, hyperpolarization of (S,S)-and (R,S)- has been calculated using theory involving the electron dipole–dipole interaction in the secular equation.
Time series forecasting is an important research topic with many practical applications. As shown earlier, the problems of lossless data compression and prediction are very similar mathematically. In this article, we propose several forecasting methods based on real-world data compressors. We consider predicting univariate and multivariate data, describe how multiple data compressors can be combined into one forecasting method with automatic selection of the best algorithm for the input data. The developed forecasting techniques are not inferior to the known ones. We also propose a way to reduce the computation time of the combined method by using the so-called time-universal codes. To test the proposed techniques, we make predictions for real-world data such as sunspot numbers and some social indicators of Novosibirsk region, Russia. The results of our computations show that the described methods find non-trivial regularities in data, and time universal codes can reduce the computation time without losing accuracy.
We study stationary solutions in the differential kinetic equation, which was introduced in Dyachenko A et al (1992 Physica D 57 96–160) for description of a local dual cascade wave turbulence. We give a full classification of single-cascade states in which there is a finite flux of only one conserved quantity. Analysis of the steady-state spectrum is based on a phase-space analysis of orbits of the underlying dynamical system. The orbits of the dynamical system demonstrate the blowup behaviour which corresponds to a 'sharp front' where the spectrum vanishes at a finite wave number. The roles of the Kolmogorov–Zakharov and thermodynamic scaling as intermediate asymptotic, as well as of singular solutions, are discussed.

Reconstruction of acoustic parameter such as acoustic velocity considers as part of inverse problems for mathematical physics and reasonable reconstruction of this parameter will assist solving interrelated problem such as inversion and imaging which are popular in the field of seismic imaging.

In this work, we studied and conducted a comparative study between two methods; the optimal control method and inverse scattering approach. In optimal control method we are using conjugate gradient method for reconstructing the desired acoustic parameter while for inverse scattering approach, we are introducing the application of Marchenko integral equation.

Furthermore, the numerical results for both approaches are presented for one dimensional problem along with the analysis from this comparative study.
We directly connect topological changes that can occur in mathematical three-space via surgery, with black hole formation, the formation of wormholes and new generalizations of these phenomena. This work widens the bridge between topology and natural sciences and creates a new platform for exploring geometrical physics.
Purpose. This article aims at analyzing anthropological data from the burial ground Berezovy Ostrov-1. The materials studied belong to the Siberian population of the Early Bronze Age. We studied the demographic situation, dental and postcranial pathologies. We also analyzed the burial rites and inventory in terms of the sex and age of the buried. Our main aim was to characterize the lifestyle, the diet and the ritual practice of this micropopulation. Results. We estimated the safety of the anthropological materials related to the Early Bronze Age community from the burial ground Berezovy Ostrov-1, analyzed the sex and age composition and pathological status of the buried and compared the demographic data of the Berezovy Ostrov-1 micropopulation with the distribution of sex and age in the Sopka-2/3 and Sopka-2/3A groups, which attribute to the Ust’-Tartas culture. As a result of sex and age identification, we found some similarities of the demographic structure of the population studied and the Ust’-Tartas groups from the burial ground Sopka-2. As for the ritual rites, we can ascertain some regularity. Stone tools, arrowheads and ornaments as objects of the same nature are typical for women, as well as for men and children. At the same time, we observe no burials of cremated women, newborns and children under 2 years old. In terms of pathologies, Berezovy Ostrov-1 site is characterized by increased frequencies of linear hypoplasia, calculus and periodontal diseases and an average frequency of caries. We can assume that the basic diet of the population included meat and wild plants, which is typical for hunter-gatherers. An increased frequency of linear hypoplasia indicates a possible famine or transferred diseases at the stage of tooth enamel formation. Our comparison with the Neolithic and Odinovo groups of the Baraba forest-steppe indicates that the diet in the Berezovy Ostrov-1 group was similar to that in the Neolithic series from Vengerovo-2A. Conclusion. The first results of our analysis reveal general correspondence of the adaptation models observed on the territory of the Novosibirsk Ob region to the characteristics of the populations of hunter-gatherers. We draw a conclusion about difficult conditions for the population of Berezovy Ostrov-1 and acute shortage of food resources. Correlation of the sex-age characteristics of the buried with the peculiarities of the funeral rite allows us to assume that there existed a special burial rite for newborns and children under the age of one year.
The plant hormone ethylene regulates numerous developmental processes and stress responses. Ethylene signaling proceeds via a linear pathway, which activates transcription factor (TF) EIN3, a primary transcriptional regulator of ethylene response. EIN3 influences gene expression upon binding to a specific sequence in gene promoters. This interaction, however, might be considerably affected by additional co-factors. In this work, we perform whole genome bioinformatics study to identify the impact of epigenetic factors in EIN3 functioning. The analysis of publicly available ChIP-Seq data on EIN3 binding in Arabidopsis thaliana showed bimodality of distribution of EIN3 binding regions (EBRs) in gene promoters. Besides a sharp peak in close proximity to transcription start site, which is a common binding region for a wide variety of TFs, we found an additional extended peak in the distal promoter region. We characterized all EBRs with respect to the epigenetic status appealing to previously published genome-wide map of nine chromatin states in A. thaliana. We found that the implicit distal peak was associated with a specific chromatin state (referred to as chromatin state 4 in the primary source), which was just poorly represented in the pronounced proximal peak. Intriguingly, EBRs corresponding to this chromatin state 4 were significantly associated with ethylene response, unlike the others representing the overwhelming majority of EBRs related to the explicit proximal peak. Moreover, we found that specific EIN3 binding sequences predicted with previously described model were enriched in the EBRs mapped to the chromatin state 4, but not to the rest ones. These results allow us to conclude that the interplay of genetic and epigenetic factors might cause the distinct modes of EIN3 regulation.
An interaction of the moving submerged circular cylinder with elastic solid ice cover is investigated. The method of reduction to integral-differential system of equations is extended to the case of elastic ice sheet floating on the fluid surface. The elastic properties of the ice are accounted for by the Euler's beam theory. A special iterative procedure is developed to construct small-time asymptotic solution for the cylinder moving with constant acceleration from rest. Elastic-gravity waves in the ice cover are studied in a wide range of parameters.
