Tsagaan Agui Cave, situated in Tsagaan Tsakhir limestone massif in the Gobi Altai Mountains of southern Mongolia, is the one of the rare stratified Holocene archaeological sites known in the Gobi Desert. During 1995-2000 excavation campaigns, cultural material spanning the late Bronze Age through the ethnographic present was recovered. In 2021, an excavation pit (2021/1) was dug in the gallery that joints the cave’s Main and Small Chambers, and an additional sondage (2021/2) was excavated in the Main Chamber itself. Excavation Unit 2021/1 is subdivided into Layers 1, 2, and 3, in which Layers 1 and 2 are attributed to the Holocene, and 3, the lowermost, is likely of Pleistocene age. Birch barkfragments bearing Old Mongolian inscriptions, cylindrical paste beads, and one additional, presumably carnelian, bead were found in Layers 1 and 2. Excavation Unit 2021/1, Layers 1-3, yielded lithic artifacts made of yellow jasper and Devonian flint, typical of the local Paleolithic industry. Only a single transparent chalcedony microblade can be tentatively dated to the Holocene. The suite of Holocene cultural material obtained during the 2021 excavations at Tsagaan Agui requires additional analysis and interpretation and is of particular interest with respect to the reconstruction of late prehistoric trade networks linking arid southern Mongolia with remote regions and the appearance of historical documents in the Gobi Desert. The study of the Holocene layers at Tsagaan Agui Cave is also of timely significance in terms of preserving Mongolian cultural heritage, since the upper layer of the site is being destroyed due to unregulated and unsupervised tourist activity in spite of its relatively remote location.
For the past five years methyl-ammonium lead trihalide perovskite solar cells have shown remarkable progress in power conversion efficiencies due to their unique properties.

Single CH3NH3PbI3 crystals were grown on the base of concentrated aqueous solution condensation of the precursor. The grown crystal structure and stoichiometry were studied by RHEED, X-ray and XPS.

The perovskite crystal photocurrent spectra were measured in the temperature range of 85-330 K.
Targeted DNA integration into known locations in the genome has potential advantages over the random insertional events typically achieved using conventional means of genetic modification.

We investigated the possibility of obtaining a suspension cell culture of Arabidopsis thaliana carrying a site-specific integration of a target gene encoding modified human interferon (dIFN) using endonuclease Cas9. For the targeted insertion, we selected the region of the histone H3.3 gene (HTR5) with a high constitutive level of expression. Our results indicated that Cas9-induced DNA integration occurred with the highest frequency with the construction with donor DNA surrounded by homology arms and Cas9 endonuclease recognition sites.

Among the monoclones of the four cell lines with knock-in studied, there is high heterogeneity in the level of expression and accumulation of the target protein. The accumulation of dIFN protein in cell lines with targeted insertions into the target region of the HTR5 gene does not statistically differ from the level of accumulation of dIFN protein in the group of lines with random integration of the transgene. However, one among the monoclonal lines with knock-in has a dIFN accumulation level above 2% of TSP, which is very high.
Betaines 5,6,7, -phosphanylidene)-1,2,3,4-tetrahydronaphthalene-1,2,4trione, 5,6,7,8-tetrafluoro-3-(methyldiphenyl-λ 5 -phosphanylidene)-1,2,3,4-tetrahydronaphthalene-1,2,4-trione, and 3-[(2,5-difluorophenyl)diphenyl-λ 5 -phosphanylidene]-5,6,7,8-tetrafluoro-1,2,3,4tetrahydronaphthalene-1,2,4-trione have been synthesized via fluorine substitution in the quinone ring of hexafluoro-1,4-naphthoquinone by tertiary phosphines RPh 2 Р (R = Ме, Ph, 2,5-F 2 C 6 H 3 ) and methanol in 90, 30 and 62% yields, respectively.The first naphthalenetrione formed also upon interaction of pentafluoro-1,4-naphthoquinone with triphenylphosphine in methanol.The new 1,4-dibenzodioxine derivative -6,11-difluoro-9-(triphenyl-λ 5 -phosphanylidene)-7,8,9,10tetrahydro-5,12-dioxatetracene-7,8,10-trione -has been obtained in a 83% yield by fluorine substitution in the benzene moiety of a naphthoquinone skeleton of this betaine by the action of pyrocatechol at the presence of potassium carbonate in DMSO.
The radiation-induced phenomena of CaSi2 crystal growth were investigated, both directly during the epitaxial CaF2 growth on Si (111) and film irradiation with fast electrons on Si (111) after its formation, while maintaining the specified film thickness, substrate temperature and radiation dose.

Irradiation in the process of the epitaxial CaF2 film growth leads to the formation of CaSi2 nanowhiskers with an average size of 5 µm oriented along the direction <110>. The electron irradiation of the formed film, under similar conditions, leads to the homogeneous nucleation of CaSi2 crystals and their proliferation as inclusions in the CaF2 film.

It is shown that both approaches lead to the formation of CaSi2 crystals of the 3R polymorph in the irradiated region of a 10 nm thick CaF2 layer.
In the present work, we study and compare the structure and sensing properties of thin films of unsubstituted palladium phthalocyanine (PdPc) and hexadecafluorosubstituted palladium phthalocyanine (PdPcF16). Thin films of PdPc and PdPcF16 were obtained by the method of organic molecular beam deposition, and their structure was studied using UV–visible spectroscopy, X-ray diffraction, and atomic force microscopy techniques. The electrical sensor response of PdPc films toward ammonia and hydrogen was investigated and compared with that of PdPcF16 films. The nature of interaction between the phthalocyanines films and some gaseous analyte molecules has been clarified using quantum chemical (DFT) calculations.
We investigated the spin coherence of high-mobility two-dimensional electron gases confined in multilayer GaAs quantum wells.

The dynamics of the spin polarization was optically studied using pump-probe techniques: time-resolved Kerr rotation and resonant spin amplification. For double and triple quantum wells doped beyond the metal-to-insulator transition, the spin-orbit interaction was tailored by the sample parameters of structural symmetry (Rashba constant), width and electron density (Dresselhaus linear and cubic constants) which allows us to attain long dephasing times in the nanoseconds range.

The determination of the scales: transport scattering time, single-electron scattering time, electron-electron scattering time, and spin polarization decay time further supports the possibility of using n-doped multilayer systems for developing spintronic devices.
A new approach to improve the light-emitting efficiency of Ge(Si) quantum dots (QDs) by the formation of an ordered array of QDs on a pit-patterned silicon-on-insulator (SOI) substrate is presented. This approach makes it possible to use the same pre-patterned substrate both for the growth of spatially ordered QDs and for the formation of photonic crystal (PhC) in which QDs are embedded. The periodic array of deep pits on the SOI substrate simultaneously serves as a template for spatially ordering of QDs and the basis for two-dimensional PhCs. As a result of theoretical and experimental studies, the main regularities of the QD nucleation on the pre-patterned surface with deep pits were revealed. The parameters of the pit-patterned substrate (the period of the location of the pits, the pit shape, and depth) providing a significant increase of the QD luminescence intensity due to the effective interaction of QD emission with the PhC modes are found.
A shallow water model of film flow is used to describe the process of a drop spreading on a horizontal plane, taking into account the liquid viscosity, heat-mass transfer and surface tension forces.

To simulate this flow numerically in polar coordinates an unconditionally stable implicit difference scheme has been developed, which (in the case of evaporation) can calculate the drop spreading over a dry surface without special allocation of the drop boundary.

A region of dimensionless parameters is singled out under which the evaporating droplet, as a result of surface tension forces, transforms into a circular ring before complete evaporation.
A range of several psychiatric medications targeting the activity of solute carrier (SLC) transporters have proved effective for treatment. Therefore, further research is needed to elucidate the expression profiles of the Slc genes, which may serve as markers of altered brain metabolic processes and neurotransmitter activities in psychoneurological disorders. We studied the Slc differentially expressed genes (DEGs) using transcriptomic profiles in the ventral tegmental area (VTA), nucleus accumbens (NAcc), and prefrontal cortex (PFC) of control and aggressive male mice with psychosis-like behavior induced by repeated experience of aggression accompanied with wins in daily agonistic interactions. The majority of the Slc DEGs were shown to have brain region-specific expression profiles. Most of these genes in the VTA and NAcc (12 of 17 and 25 of 26, respectively) were downregulated, which was not the case in the PFC (6 and 5, up- and downregulated, respectively). In the VTA and NAcc, altered expression was observed for the genes encoding the transporters of neurotransmitters as well as inorganic and organic ions, amino acids, metals, glucose, etc. This indicates an alteration in transport functions for many substrates, which can lead to the downregulation or even disruption of cellular and neurotransmitter processes in the VTA and NAcc, which are attributable to chronic stimulation of the reward systems induced by positive fighting experience. There is not a single Slc DEG common to all three brain regions. Our findings show that in male mice with repeated experience of aggression, altered activity of neurotransmitter systems leads to a restructuring of metabolic and neurotransmitter processes in a way specific for each brain region. We assume that the scoring of Slc DEGs by the largest instances of significant expression co-variation with other genes may outline a candidate for new prognostic drug targets. Thus, we propose that the Slc genes set may be treated as a sensitive genes marker scaffold in brain RNA-Seq studies.
The dynamics of hydrocarbon generation by the Jurassic and Cretaceous source rocks in the northeastern part of the Bolshaya Kheta megasyneclise

was reconstructed by historical and geological modelling

The amounts of liquid and gaseous hydrocarbons generated by these sources rocks were estimated for each time period and catagenetic substage
Solid solutions La0.5Ca0.5Mn1-xFexO3synthesized by the method of polymer-salt compositions at a temperature of 900 °C with the perovskite structure were tested in the methane oxidation reaction.It was shown that at 600 °C, complete conversion of methane occurs for all compositions, however, the nature of the dependence of the degree of conversion for lower temperatures is not linear and depends on the chemical composition.The formation of planar defects in the direction of crystallographic planes (101) in the perovskite structure at the stage of the synthesis of solid solutions and the appearance of nanoparticles of Ca-Mn oxides on the surface of perovskite after participation after reaction were shown by the HRTEM method.
Hyperpolarisationsverstärkte Magnetresonanztomographie kann zur Untersuchung biomolekularer Prozesse im Körper verwendet werden, erfordert aber die Verwendung von Hetero‐Kernen wie 13 C, 15 N oder 129 Xe. Hier stellen wir eine neue Art der Hyperpolarisierten Protonen Bildgebung vor, bei der die hyperpolarisierte Spinordnung in einem nicht magnetischen und langlebigen korrelierten (Singulett‐) Zustand eingeschlossen ist und nur durch eine spezifische biochemische Reaktion für die Bildgebung freigesetzt wird. In dieser Arbeit erzeugen wir hyperpolarisiertes Fumarat durch chemische Reaktion eines Eduktes mit para‐angereichertem Wasserstoffgas. Der Singulettzustand der Fumarat Protonen wird als Antiphasen‐NMR‐Signale durch enzymatische Umwandlung zu Malat in D 2 O freigesetzt. Anhand dieses Modellsystems zeigen wir zwei Pulssequenzen, um die NMR‐Signale für die Bildgebung zu rephasieren und die Hintergrundsignale von Wasser zu unterdrücken. Die hier vorgestellte hyperpolarisationsverstärkte Protonen Bildgebungstechnik ermöglicht eine hyperpolarisierte Bildgebung, ohne dass hierfür Hetero‐Kerne mit ihrer niedrigen natürlichen Häufigkeit und geringen Empfindlichkeit benötigt werden.
The article notes the tendency towards the preferred choice of the preposition pro (about) (instead of o) in modern Russian speech. The above said leads to a change in the compatibility of the accusative word form with the explanatory meaning, to an expansion of the range of verbs and nouns that control this form.

Observations on the use of the so-called 'The Accusative of theme' in media speech allowed us to identify different communicative intentions of the speaker, which are marked by the word form pro (about) N4: fixation of the topic, announcement, continuation and development, return to the topic, change of topic, forecast, clarification, accentuation.

In addition, as part of the predicate, the word form with the preposition pro (about) is used as a means of the object of speech / thought characterization. In these syntactic conditions, a new way of defining the concept is formed: X eto pro (is about) N4, as well as a new question: What is X about? They are actively used in speech by adherents of the newest rhetorical canon – as opposed to the traditional one.
At FSE 2004, Lipmaa et al. studied the additive differential probability adp⊕(α,β → γ) of exclusive-or where differences α,β,γ ∈ Fn2 are expressed using addition modulo 2n. This probability is used in the analysis of symmetric-key primitives that combine XOR and modular addition, such as the increasingly popular Addition-Rotation-XOR (ARX) constructions. The focus of this paper is on maximal differentials, which are helpful when constructing differential trails. We provide the missing proof for Theorem 3 of the FSE 2004 paper, which states that maxα,βadp⊕(α,β → γ) = adp⊕(0,γ → γ) for all γ. Furthermore, we prove that there always exist either two or eight distinct pairs α,β such that adp⊕( α,β → γ) = adp⊕(0,γ → γ), and we obtain recurrence formulas for calculating adp⊕. To gain insight into the range of possible differential probabilities, we also study other properties such as the minimum value of adp⊕(0,γ → γ), and we find all γ that satisfy this minimum value.

A report on the scientific journey to the Ningxia-Hui Autonomous Region of the PRC in July 2019 is presented. During the journey the authors consulted Chinese rock art specialists, visited the Historical Museum of the Ningxia Province, Museum of Western Xia (Xi Xia), Helankou Rock Art Museum and the Helankou and Damaidi rock art sites in Helan and Zhongwei counties of the Ningxia-Hui Autonomous Region.

Brief descriptions of the rock art sites and museum collections are given.
Amorphous silicon (α-Si) film present an inexpensive and promising material for optoelectronic and nanophotonic applications. Its basic optical and optoelectronic properties are known to be improved via phase transition from amorphous to polycrystalline phase. Infrared femtosecond laser radiation can be considered to be a promising nondestructive and facile way to drive uniform in-depth and lateral crystallization of α-Si films that are typically opaque in UV-visible spectral range. However, so far only a few studies reported on use of near-IR radiation for laser-induced crystallization of α-Si providing less information regarding optical properties of the resultant polycrystalline Si films demonstrating rather high surface roughness. The present work demonstrates efficient and gentle single-pass crystallization of α-Si films induced by their direct irradiation with near-IR femtosecond laser pulses coming at sub-MHz repetition rate. Comprehensive analysis of morphology and composition of laser-annealed films by atomic-force microscopy, optical, micro-Raman and energy-dispersive X-ray spectroscopy, as well as numerical modeling of optical spectra, confirmed efficient crystallization of α-Si and high-quality of the obtained films. Moreover, we highlight localized laser-induced crystallization of α-Si as a promising way for optical information encryption, anti-counterfeiting and fabrication of micro-optical elements.
Modern world trends have a significant impact on the university and human capital as an important part of the university. From our point of view, an active process is currently underway and namely it is transition from a university-function, to a university-subject of change. Only a small amount of the university's academic staff have the necessary competences for the implementation of full-life projects and the ability to work in a project team, this is primarily due to the lack of soft-skills.

In this regard, to assess the capitalization of the human resource in the university community, in this article propose to introduce the concept of capitalization index (CI), which takes into account the diversity of activities of the university staff (scientific work, teaching, interaction with students, etc.) and determines its effectiveness.

This system allows us to supplement it with various components, depending on the trends of development of the university, and also shift the focus from one area to another (priority factor) and strengthen the significance of a certain type of activity (quality factor).
Adipose tissue is considered one of the endocrine organs in the body because of its ability to synthesize and release a large number of hormones, cytokines, and growth and vasoactive factors that influence a variety of physiological and pathophysiological processes, such as vascular tone, inflammation, vascular smooth muscle cell migration, endothelial function, and vascular redox state. Moreover, genetic factors substantially contribute to the risk of obesity. Research into the biochemical effects of molecules secreted by visceral adipocytes as well as their molecular genetic characteristics is actively conducted around the world mostly in relation to pathologies of the cardiovascular system, metabolic syndrome, and diabetes mellitus. Adipokines could be developed into biomarkers for diagnosis, prognosis, and therapeutic targets in different diseases. This review describes the relevance of secretory activity molecules of visceral adipocytes in cardiovascular disease associated abdominal obesity.
We present a measurement of the asymmetry A_{CP} between same-sign inclusive dilepton samples ℓ^{+}ℓ^{+} and ℓ^{-}ℓ^{-} (ℓ=e, μ) from semileptonic B decays in ϒ(4S)→BB[over ¯] events, using the complete data set recorded by the BABAR experiment near the ϒ(4S) resonance, corresponding to 471×10^{6} BB[over ¯] pairs. The asymmetry A_{CP} allows comparison between the mixing probabilities P(B[over ¯]^{0}→B^{0}) and P(B^{0}→B[over ¯]^{0}), and therefore probes CP and T violation. The result, A_{CP}=[-3.9±3.5(stat)±1.9(syst)]×10^{-3}, is consistent with the standard model expectation.
AgGd(MoO4)2:Ho3+/Yb3+ double molybdates with five concentrations of Ho3+ and Yb3+ were synthesized by the microwave employed sol–gel based process (MES), and the crystal structure variation, concentration effects, and spectroscopic characteristics were investigated.

The crystal structures of AgGd1−x−yHoxYby(MoO4)2 (x = 0, 0.05; y = 0, 0.35, 0.4, 0.45, 0.5)at room temperature were determined in space group I41/a by Rietveld analysis. Pure AgGd(MoO4)2 has a scheelite-type structure with mixed occupations of (Ag,Gd) sites and cell parameters a = 5.24782 (11) and c = 11.5107 (3) Å, V = 317.002 (17) Å3, Z = 4. In doped samples, the sites are occupied by a mixture of (Ag,Gd,Ho,Yb) ions, which provides a linear cell volume decrease with the doping level increase. The evaluated photoluminescence and Raman spectroscopic results were discussed in detail.

Under the excitation at 980 nm, AGM:0.05Ho,yYb phosphors exhibited a yellowish green emission composed of red and green emission bands according to the strong transitions 5F5 → 5I8 and 5S2/5F4 → 5I8 of Ho3+ ions. The upconversion intensity behavior dependent on the Yb/Ho ratio is explained in terms of the optimal number of Yb3+ ions at the characteristic energy transfer distance around the Ho3+ ion.
. A quantitative physical model, describing the piezoelectric electromechanical coupling in nanomechanical resonators with a two-dimensional electron gas, is developed. Numerical calculations of the change in density of a two-dimensional electron gas contained in a vibrating cantilever are performed using the model and are shown to be consistent with the experiment. The obtained data show that the vibration-induced electron density modulation is localized near the clamping point and that it is related to a rapid spatial change in the mechanical stress near this point. It is shown that details of the clamping geometry significantly affect the magnitude of the effect.
The construction of the scheme is based on a fourth-order three-exponential scheme, which contains only one exponent with a spectral parameter.

A fourth-order multi-exponential scheme is proposed for the Zakharov-Shabat system. The scheme represents a product of 13 exponential operators. This exponent is factorized to the fourth-order with the Suzuki formula of 11 exponents.

The obtained scheme allows the use of a fast algorithm in calculating the initial problem for a large number of spectral parameters and conserves the quadratic invariant exactly for real spectral parameters.
Precise study of the hadrons production in e+e- annihilation at low energies provides important information about interactions of light quarks and spectroscopy of their bound states. These studies are especially important for theoretical calculations of the muon (g-2) via the Standard Model because of the present difference between theoretical and experimental values exceeds three standard deviations.

In this report we will discuss current status and recent results obtained by the CMD-3 experiment and will give a brief look to status of the BaBar and Belle II experiments.
