We measure the branching fractions of ${B}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}{\ensuremath{\eta}}^{(\ensuremath{'})}$ decays with the complete Belle data sample of $772\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ events collected at the $\ensuremath{\Upsilon}(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. The results for the branching fractions are: $\mathcal{B}({B}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\eta})=(12.3{\ifmmode\pm\else\textpm\fi{}}_{1.7}^{1.8}\ifmmode\pm\else\textpm\fi{}0.7)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}6}$ and $\mathcal{B}({B}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}{\ensuremath{\eta}}^{\ensuremath{'}})<7.4\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}6}$ at 90% confidence level. The $\ensuremath{\eta}\mathrm{\text{\ensuremath{-}}}{\ensuremath{\eta}}^{\ensuremath{'}}$ mixing angle is constrained to be less than 42.2\ifmmode^\circ\else\textdegree\fi{} at 90% confidence level.
The arising of the cavitation cavity behind the circular cylinder with aspect ratio 0.06 has been investigated using high-speed visualization. High-speed imaging at a sampling rate up to 200 kHz and even higher for the local areas allowed the spatial structure and dynamics of gas-vapor cavities thoroughly to be studied. The time dependence of the volume of the cavitation cavity on time was obtained for all investigated regimes. The vapor volume fraction, as expected, was found to increase with a decrease in cavitation number at higher flowrates. The feature of the separated cavitation cavity behind the cylinder is the complex structure consisting of the set of the flatted bubbles with a thin liquid interface between them. The collapse of the cavitation cavity proved to be always initiated only near one of the channel walls.
The paper is devoted to the topical problem of determining the sources of methane from observational data. An algorithm based on the statistical optimization method used to estimate a time constant parameter is considered. To implement the algorithm, a variant of ensemble smoothing is used, which is an optimal estimate of the desired parameter based on observational data and forecast for a given time interval. This paper presents the implementation of the algorithm for real observational and forecast data, the results of a three-dimensional transport and diffusion model are taken as a mathematical model, and satellite measurement data are used as observational data. Methane fluxes are estimated in subdomains of the Earth’s surface for specified time intervals. The paper contains a mathematical formulation of the problem, a scheme for its numerical implementation. The results of numerical experiments with model and real data are presented.
In TAIGA Observatory (Tunka Advanced Instrument for cosmic ray physics and Gamma-ray Astronomy) we are commissioning the first Imaging Atmospheric Cherenkov Telescope (IACT).

The telescope has an alt-azimuth mount and 17-bit shaft encoder for each axis, stepper motors are used for axis control. For the pointing calibration of the telescope a CCD-camera is installed on the dish of the telescope and its position allows to capture simultaneously both the Cherenkov camera with LEDs and the sky with observed source.

Since October 2017, the telescope has been operating in tracking mode. In this work the TAIGAIACT telescope pointing calibration approach and first results of the tracking operations are described.
The collocation and least residuals (CLR) method combines the methods of collocations (CM) and least residuals. Unlike the CM, in the CLR method an approximate solution of the problem is found from an overdetermined system of linear algebraic equations (SLAE). The solution of this system is sought under the requirement of minimizing a functional involving the residuals of all its equations. On the one hand, this added complication of the numerical algorithm expands the capabilities of the CM for solving boundary value problems with singularities. On the other hand, the CLR method inherits to a considerable extent some convenient features of the CM. In the present paper, the CLR capabilities are illustrated on benchmark problems for 2D and 3D Navier–Stokes equations, the modeling of the laser welding of metal plates of similar and different metals, problems investigating strength of loaded parts made of composite materials, boundary-value problems for hyperbolic equations.
The essay is concerned with decoding the subject (cognitive) content of R. Kipling's The Spies' March, notable mainly for its proud name. The problem is that the text is created using the double coding technique; it is fundamentally ambiguous and can be read in two ways, allowing in both cases various cognitive and semantic interpretations in the modern historical and cultural context. The spy attribution of the March is a clever deception, created first by the author in the hope that the readership will be able to uncover his language game following the old adage “a good [poetic] witch covers her tracks, but a better [semiotic] one can uncover them”. That’s what they call now research, investigation or enquiry, depending on purpose and circumstances. He refers to “spies” as epidemiologists who fought the outbreak of plague in Manchuria in 1911. For Kipling, it was a language game, the poetic purpose of which was to describe in purely military terms and partly in Bible language of the Apocalypse the fight against the epidemic, which, in its intrinsic “quest” for globalization, threatened to outgrow into a pandemic. Unfortunately, the readers proved to be too gullible, neglecting to analyze biblical references of The March and its dramatized composition in which two choruses are opposed to each other and which is preceded by a distant Voice; they often trusted the title’s literal meaning, and preferred to read The March as glorification of spies. To do this, it is just enough to “turn” the Yellow Flag of the original (a symbol of a pandemic disaster) into a proud one, a flag of dignity and fame. In Russia, translators have also joined this process. Details of such a false-negative decryption are presented in the section entitled “Lexical, symbolic and discursive keys for decoding The March”. The technique of creating and decoding an ambivalent text is, of course, the main object of theoretical analysis. Nevertheless, in terms of application, the potential use of the key ideological “messages” of The March in the global information and political environment, giving now a lot of place to politainment as well as infotainment, is even more important to explore. We consider two major “messages”: «There are not leaders to lead us to honour» и «Bring us deliverance, spy!». The tasks of such a politainment entreprise might be to form a causal relationship between these two Kipling’s brainchilds, namely, to personalize the "spy" in the international media discourse and entrust him with the implementation of Kipling's order regarding deliverance from current “calamities”. The mainstream media trend shows that the greatest chances to become such a “spy” has VP, which recently also received from Roland Lombardi, by analogy with the devout Lawrence of Arabia, the informal title of Arabian (Poutine d’Arabie). To do it, it’s enough for western media to add inverted commas when mentioning his nickname.
Black crystal, a new mutant of coat color pattern occurring in the American mink in the course of selection for domestic behavior, is described.

Breeding data demonstrate that the novel color phase is inherited as a monogenic autosomal semidominant trait. The mutant gene is designated as Black crystal and is symbolized by Cr.

The Cr gene is not allelic to the multiple-allelic series at the Black cross locus. A salient feature of the mutation is the appearance of white guard hairs producing a veil-like covering of the body. In the Black crystal homozygote, coat color is of the Himalayan type.
Autism spectrum disorder (ASD) is characterized by uncommon genetic heterogeneity and a high heritability concurrently. Most autoimmune disorders (AID), similarly to ASD, are characterized by impressive genetic heterogeneity and heritability.

We conducted gene-set analyses and revealed that 584 out of 992 genes (59%) included in a new release of the SFARI Gene database and 439 out of 871 AID-associated genes (50%) could be attributed to one of four groups: 1. FMRP (fragile X mental retardation protein) target genes, 2. mTOR signaling network genes, 3. mTOR-modulated genes, and 4. vitamin D3-sensitive genes. The network analysis revealed 3124 interactions between 528 out of 729 AID genes for the 0.7 cutoff.

With the exception of FMRP targets, which are obviously associated with the direct involvement of local translation disturbance in the pathological mechanisms of ASD, the remaining categories are represented among AID genes in a very similar percentage as among ASD predisposition genes. Thus, mTOR signaling pathway genes make up 4% of ASD and 3% of AID genes, mTOR-modulated genes—31% of both ASD and AID genes, and vitamin D-sensitive genes—20% of ASD and 23% of AID genes. The great majority (up to 67%) of AID genes are related to the mTOR signaling pathway directly or indirectly. Our present research and available published data allow us to hypothesize that both a certain part of ASD and AID comprise a connected set of disorders sharing a common aberrant pathway (mTOR signaling) rather than a vast set of different disorders. Furthermore, an immune subtype of the autism spectrum might be a specific type of autoimmune disorder with an early manifestation of a unique set of predominantly behavioral symptoms.
Small differences in the reactivity of weakly nucleophilic potassium aryltrifluoroborates are revealed in the silver-assisted Pd-catalyzed cross-coupling of K[4-RC6F4BF3] (R = H, Bu, MeO, EtO, PrO, iPrO, BuO, t-BuO, CH2=CHCH2O, PhCH2O, PhCH2CH2O, PhO, F, pyrazol-1-yl, pyrrol-1-yl, and indol-1-yl) with ArX (4-BrC6H4CH3, 4-IC6H4F and 3-IC6H4F). An assumed role of silver(I) compounds Ag m Y (Y = O, NO3, SO4, BF4, F) consists in polarization of the Pd-X bond in neutral complex ArPdL n X with the generation of the related transition state or formation of [ArPdL n ][XAg m Y] with a highly electrophilic cation and subsequent transmetallation with the weakly nucleophilic borate. Efficiency of Ag m Y as a polarizing agent decreases in order Ag2O > AgNO3 ≈ Ag2SO4 > Ag[BF4] > AgF. No clear correlation between the reactivity of K[4-RC6F4BF3] and substituent electron parameters, σI and σR°, of the aryl group 4-RC6F4 was found.
We experimentally demonstrate a previously unforeseen nonlinear effect in optical fibers: up-conversion luminescence generation excited by multiphoton absorption of femtosecond infrared pulses.

We directly estimate the average number of photons involved in the up-conversion process, by varying the wavelength of the pump source.

We highlight the role of nonbridging oxygen hole centers and oxygen-deficient center defects and directly compare the intensity of side-scattered luminescence with numerical simulations of pulse propagation.
Tuberculosis (TB) is a common disease caused by infection of Mycobacterium tuberculosis and influenced by host hereditary and environmental factors. Accumulated genomic data obtained through the use of new methodological approaches, including analysis of associative networks, contribute to the understanding of the hereditary basis of the disease.

In the current study, we carried out the reconstruction and analysis of associative network representing molecular genetic links between proteins/genes involved in the development of TB.

In the associative network, well studied proteins and genes with a decisive importance in the efficiency of the human immune response against a pathogen predominated. However, this approach identified 12 new genes encoding for the respective proteins in the associative network polymorphismsof which has not been studied regarding the development of TB.
While metal-organic frameworks based on aromatic carboxylates are very numerous and well investigated

the chemistry of their fully fluorinated analogues is at the very beginning. This minireview aims at summarizing all metal complexes with octafluorobiphenyl-4,4′-dicarboxylate (oFBPDC 2− ) anion and in particular, porous coordination polymers, their syntheses, crystal structures and functional properties

highlighting the importance of further investigation of such systems.
Physical roots of the model are in recent advances of the theory of weak turbulence of wind‐driven waves that predicts the link of instant wave energy to instant energy flux to/from waves.

A physical model for sea wave period from altimeter data is presented. The model operates with wave height and its spatial derivative and does not refer to normalized radar cross‐section σ 0 measured by the altimeter. Thus, the resulting formula for wave period does not contain any empirical parameters and does not require features of particular satellite altimeter or any calibration for specific region of measurements.

A single case study illustrates consistency of the new approach with previously proposed empirical models in terms of estimates of wave periods and their statistical distributions. The paper brings attention to the possible corruption of dynamical parameters such as wave steepness or energy fluxes to/from waves when using the empirical approaches. Applications of the new model to the studies of sea wave dynamics are discussed.
In this paper, new method for determining the mechanical characteristics of nanoparticles in a heterogeneous mixture is proposed. The heterogeneous mixture consists of a thermosetting epoxy resin and silicon dioxide powder of different dispersity. The mechanical characteristics of such a material at a constant concentration for nanopowder are experimentally determined. Using existing formulas for obtaining effective characteristics, the Lame coefficients for nanoparticles of various sizes are calculated. The dependence of the elastic characteristics on the particle size is obtained.
The evolution of the artificial wave packet in the supersonic boundary layer of swept wing was experimentally studied for the first time by hot-wire measurements. The localized disturbances were generated by pulse glow discharge.

Analysis of the mean flow, integral dependences, the averaged waveforms of wave packet and spectral data analysis in supersonic boundary layer of swept wing has been executed. Estimates of the velocity of propagation of controlled disturbances downstream are made.

A comparison of the wave packet development in the boundary layer of a swept wing at two Mach numbers is given.
The dynamics of photodissociation of PCl3 at 235 nm has been studied by monitoring of ground state Cl(2P3/2) and spin-orbitally excited Cl(2P1/2) atoms by REMPI technique. Also, the P+, PCl+, PCl+, and PCl+ photoions have been monitored non-resonantly in parallel with detection of REMPI-produced Cl+ ions.

The speed distributions and speed-dependent anisotropy ± parameters β for all these particles have been determined by three-dimensional photofragment ion imaging technique.

The β parameters are close to zero for all these particles. The relative yields of excited Cl(2P1/2) atoms for photodissociation of PCl3 is 0.49 0.03. The speed distributions of Cl(2P3/2) and Cl(2P1/2) atoms are bimodal. We explain the bimodal distributions as a result of competition between two REMPI channels. One channel is far-from-resonance one-photon photodissociation, the another channel is near-resonant two-photon ionisation followed by near-resonance one-photon photodissociation.
Recently, many interdisciplinary community researchers have focused their efforts on study of the low-level light irradiation effects (photobiomodulation, PBM) as a promising therapeutic technology. Among the priorities, a search of new wavelength ranges of laser radiation to enhance the laser prospects in treatment of autoimmune and cancer diseases commonly accompanied by disorders in the antioxidant system of the body.

Here, we report comprehensive biomolecular studies of the changes in the BALB/c nude mice skin after an exposure to the continuous laser radiation at the 1270 nm wavelength and energy densities of 0.12 and 1.2 J/cm 2 .

Such regime induces both local and systemic PBM effects, presumably due to the short-term increase in ROS levels, which in turn activate the cell antioxidative system.
In this paper, we show that every finite spatial graph is a connected sum of a planar graph, which is a forest, and a tangle. As a consequence, we get that any finite spatial graph is a connected sum of a planar graph and a braid. Using these decompositions it is not difficult to find a set of generators and defining relations for the fundamental group of compliment of a spatial graph in 3-space [Formula: see text].
Light scattering is one of the most important elementary processes in near-field optics.

We build up the Born series for scattering by dielectric bodies with sharp boundaries. The Green's function for a two-dimensional homogeneous dielectric cylinder is obtained. As an example, the formulas are derived for a scattered field of two parallel cylinders.

The polar diagram is shown to agree with the numerical calculation by the known methods of discrete dipoles and boundary elements.

эти очень маленькие, длиной 1.5-2.8мм, беспозвоночные животные населяют предгорные и горные реки Азии и Северной Америки.Семейство Nymphomyiidae установлено в 1932 г. известным японским диптерологом М
The paper describes the current state of agent-based modeling of geographical space and spatial economic systems. We explore reasons why this approach to modeling spatial phenomena is of particular interest. Agent-based models (ABMs) allow accounting for agents’ spatial heterogeneity, the existing structure of the space, locality of interactions between agents. A survey of approaches to introducing space into the models and examples of the existing spatial models is presented. There is a great variety of spatial ABMs, but they relate predominantly to the local and city level, rather than to the economy as a whole. Spatial ABMs at the level of large regions and countries are not yet sufficiently developed, but have good prospects in the future. With increasing availability of geodata and technological development in general the number of applications and coverage of spatial ABM will grow
Purpose. We considered and analyzed the finds of iron arrowheads from a small collection of armament objects for long-range combat related to the epoch of Kyrgyz Great Power. The collection is exhibited at the moment in the National Museum of the Kyrgyz Republic in Bishkek City. Results. Precise location of these objects is not determined. However, it is known that all these objects of armament originate from the territory of modern Kyrgyzstan. The arrowheads from the collection have been preserved quite well, which distinguishes these findings from the armament objects of excavations of archaeological monuments of the cultures of ancient and medieval peoples in the Tian Shan. Having carried out a formal and typological classification analysis of the items from the collection, we determined a certain typological identity of the armament for longrange combat that were related to different groups and types of iron petiolate arrowheads according to the section and the form of feather. We found analogues to the arrows from our collection when discovered arrowheads of similar forms as a part of weapon complexes of ancient and medieval ethnicities inhabiting the Central Asian historical and cultural region during the Ancient times, Early and High Middle Ages. We traced the spread of arrowheads of different types, analyzed them as a part of our collection, and analyzed the items discovered in the course of previous research in medieval archaeological sites on the territory of northern Tian Chan Region in the bounds of Kyrgyzstan. The results of our analysis prove that all the arrowheads from the collection studied relate to the historical eras of the Early and High Middle Ages. Conclusion. A part of this collection is likely to have belonged to the complex of means for long-range combat. They used such arrowheads while shooting the enemy in the epoch of the Kyrgyz Khanate. Preponderance of armorpiercing and versatile iron arrowheads can testify the necessity to confront enemies in long-range combats and fight against adversaries who were powerfully armed and fully-equipped with metallic armor.
Music recommender systems (MRS) help users of music streaming services to find interesting music in the music catalogs. The sparsity problem is an essential problem of MRS research. It refers to the fact that user usually rates only a tiny part of items. As a result, MRS often has not enough data to make a recommendation.

To solve the sparsity problem, in this paper, a new approach that uses related items' ratings is proposed. Hybrid MRS based on this approach is described. It uses tracks, albums, artists, genres normalized ratings along with information about relations between items of different types in the music catalog.

The proposed MRS is evaluated and compared to collaborative method for users' preferences prediction.
Depression is the most frequently diagnosed psychiatric disease in Western countries.Although a variety of pharmacological treatments for this disorder are available, a significant proportion of patients is treatmentresistant and/or suffer from side effects.There is a growing need for a complex understanding of the underlying pathogenic mechanisms in the neural circuits and effort for developing novel therapies for the depression.The role of serotonin in depression and antidepressant treatment remains unclear despite decades of research.New optogenetic tools for manipulation of neuronal activity have enabled the investigation of the contribution of distinct neural circuit elements to the pathogenesis of depression.In this study, we used the specific lentiviral vectors for the inhibition of serotonergic neurons.The proton pump archaerhodopsin-3 (eArchT3.0)has been expressed in the serotonergic neurons under the control of tryptophan hydroxylase 2 promotor.Green light stimulation of eArchT3.0 expressing neurons led to a reduced percentage of c-Fos expressing cells among thоse neurons, which indicates a decrease in their activity.
Major (CD9, CD63, CD81) and others (CD82, CD151, Tspan8) tetraspanins are widely represented in exosomes, where they interact with various proteins and form functional tetraspanin complexes. Tetraspanin complexes include proteases.

Tetraspanin-associated exosomal proteases (ADAM proteases, MMPs, EMMPRIN) play an important role in the processes of cell motility, migration, invasion and formation of metastases.

Also, a significant contribution to tumor progression is made by proteases that are not associated with tetraspanins. They destabilize intercellular contacts, promote migration and invasion of tumor cells, participate in the regulation of the expression IGF-I, VEGF and transcription factors activation/deactivation. The role of other proteases of exosomes in the processes of tumor progression is being clarified.
