This paper deals with the acoustic features of the Surgut Khanty consonants. The research is based on the data gathered during fieldwork in Kogalym town (2018) and the Ugut village (2019). The audio samples are provided by three native speakers of the Tromjegan, Malyi Yugan, and Bolshoi Yugan idioms. The total size of the sample database numbers more than six thousand isolated consonant pronouncements. The data for the research was obtained using oscillographic and spectrographic methods, formant locus analysis, spectral moment analysis. The analysis was performed via Praat and Emu-SDMS software. Oscillograghy and spectrography methods reveal that voiceless fricative phonemes may be voiced in intervocalic distribution. It is common for the sonants to become devoiced in the final and preconsonantal positions. Moreover, due to devoicing, different phonemes may acquire low-obstruent and obstruent consonant features. For the fricative, lateral-fricative consonants, affricates spectral moment analysis has been carried out. The spectral moments technique gives an opportunity to represent complex noise data as a relatively small set of numbers that can be processed statistically. According to the data on spectral moments, four types of noise have been defined: high-frequency low-dispersion noise resembling /s/, medium-frequency low-dispersion noise resembling /ʃ/, /tʃ/, /cc/, low-frequency medium-dispersed noise for phonemes /ɫ/, / /, low-frequency dispersed noise for phonemes /w/, /γ/. The forman analysis is used o es ima e onsonan resonan frequen ies. As shown by he formant locus analysis, the smallest values of the second formant locus are associated with the labial and velar phonemes. Larger values are associated with the coronal phonemes. The largest ones are specific to the palatal phonemes. At the same time, the acoustic features make it possible to stably distinguish the nasal /n/ - /ɲ/, wherein the opposition of the middle and fron lingual ar i ula ions is observed only in some speakers’ re ordings for the pairs /ɫ/ - / /, /tʃ/ - /cc/.
Readily accessible monoterpenes α-pinene and ß-pinene are of interest as starting material for preparation of certain chiral derivatives, annelated heterocycles in particular.Recently utilisation of pinanederived α,β-unsaturated ketones for the synthesis of phenantrolines (1) and pyridines (2) fused with pinane frame were reported.The heterocycles cited are prospective chiral auxiliaries.The alternative route to heterocycles annelated with the pinane carbon frame is the use of pinocarvone oxime, which is readily prepared via nitrosochlorination of α-pinene.We reported earlier preparation of pyrazole and isoxazole-type heterocycles annelated with pinane skeleton (3).Isoxazoles and ß-enaminocarbonyl compounds are known to be the convenient starting material for preparation of different types of azaheterocycles (4,5,6).

Now we report the synthesis of pinane-derived enaminoaldehyde and new annelated heterocycles of pyridine and pyrimidine type. Results and discussion.Isoxazole 2 (both optically active and racemic) was prepared from (-)-a-pinene and (±)-a-pinene correspondingly according to published procedure (3).In order to obtain ß-enaminocarbonyl derivative of pinane type we studied hydrogenolysis of isoxazole 2 (Scheme 1).Surprisingly, hydrogenation of isoxazole 2 proceeds at ambient pressure to give enaminoaldehyde 3 in noticeable yield only in the presence of significant amount of the catalyst 5% Pd/C (1:1 w/w).However, hydrogenation of compound 2 at 4-5 atm H 2 over 5% Pd/C catalyst (10:1 w/w) gave enaminoaldehyde 3 in 89% yield.Despite chemistry of aminoaldehydes has been scrupulously reviewed, only few examples of the use of aliphatic enaminoaldehydes for preparation of heterocyclic compounds are known(7).Reactions of chiral

Synthesis of new chiral fused pyridines and pyrimidines with pinane carbon frame prospective as bioactive compounds is described.Heterocylisations of pinane-derived ßenaminoaldehyde, need generally more rigid conditions than for o-aminobenzaldehyde, probably, both due to sterical and electronic reasons.
The notion of a word-representable graph has been studied in a series of papers in the literature. A graph $G=(V,E)$ is word-representable if there exists a word $w$ over the alphabet $V$ such that letters $x$ and $y$ alternate in $w$ if and only if $xy$ is an edge in $E$. If $V =\{1, \ldots, n\}$, this is equivalent to saying that $G$ is word-representable if for all $x,y \in \{1, \ldots, n\}$, $xy \in E$ if and only if the subword $w_{\{x,y\}}$ of $w$ consisting of all occurrences of $x$ or $y$ in $w$ has no consecutive occurrence of the pattern 11.

In this paper, we introduce the study of $u$-representable graphs for any word $u \in \{1,2\}^*$. A graph $G$ is $u$-representable if and only if there is a vertex-labeled version of $G$, $G=(\{1, \ldots, n\}, E)$, and a word $w \in \{1, \ldots, n\}^*$ such that for all $x,y \in \{1, \ldots, n\}$, $xy \in E$ if and only if $w_{\{x,y\}}$ has no consecutive occurrence of the pattern $u$.

We show that for any $k \geq 3$, every finite graph $G$ is $1^k$-representable. This contrasts with the fact that not all graphs are 11-representable graphs.The main focus of the paper is the study of $12$-representable graphs. In particular, we classify the $12$-representable trees. We show that any $12$-representable graph is a comparability graph and the class of $12$-representable graphs include the classes of co-interval graphs and permutation graphs. We also state a number of facts on $12$-representation of induced subgraphs of a grid graph.
The article provides a kinetic description of the plasma equilibrium in the Beklemishev diamagnetic trap, where the traditional approach based on the theory of magnetic drifts is not applicable, since the ions move in a substantially non-circular orbit, the diameter of which is approximately equal to the diameter of the diamagnetic bubble.

The ion distribution function was found in the collisionless approximation, neglecting the diamagnetic electron current. The radial profile of the magnetic field, the plasma density, the current density, and the components of the pressure tensor are calculated. An adiabatic invariant is calculated that replaces the magnetic moment, which is not conserved in the diamagnetic bubble.

It was found that the width of the boundary layer in the diamagnetic bubble varies from 6 to 8 Larmor radii calculated by a vacuum magnetic field. The criterion of absolute confinement is formulated and the plasma equilibrium is found for the case when the adiabatic invariant is not conserved and only ions whose velocity satisfies the criterion of absolute confinement are trapped.
Seismic tomography provides a window into magmatic plumbing systems; however, obtaining sufficient data for ‘real-time’ imaging is challenging. Until now, syn-eruptive tomography has not been successfully demonstrated. For the first time, we obtained high-resolution images of Earth's interior during an ongoing volcanic eruption. We used data from 11,349 earthquakes, most of which during La Palma eruption (19 September-13 December, 2021), to perform travel-time seismic tomography. We present high-precision earthquake relocations and 3D distributions of P and S-wave velocities highlighting the geometry of magma sources. We identified three distinct structures: (1) a shallow localised region (< 3 km) of hydrothermal alteration; (2) spatially extensive, consolidated, oceanic crust extending to ~10 km depth and; (3) a large (> 400 km 3 ) sub-crustal magma-filled rock volume intrusion extending from ~7 to 25 km depth. Our results suggest that this large magma reservoir feeds the La Palma eruption continuously for almost three months. Prior to eruption onset, magma ascended from ~10 km depth to the surface in < 7 days. In the upper 3 km, melt migration is along the western contact between consolidated oceanic crust and altered hydrothermal material. Similar structural weaknesses along the eastern contact could potentially cause new eruptive centres in the future.
CPT-violation due to $e^+ e^-$ mass difference

demonstrate that CPT-violation generates a non-zero photon mass

cosmological bounds on the photon mass lead to bounds on $e^+ e^-$ mass difference which are at least by 10 orders of magnitude stronger than the direct experimental bound
Generation of the cosmological baryon asymmetry in frameworks of spontaneous baryogenesis is studied in detail.

It is shown that the relation between baryonic chemical potential and the time derivative of the (pseudo)Goldstone field essentially depends upon the representation chosen for the fermionic fields with non-zero baryonic number (quarks). Kinetic equation is modified and numerically solved in equilibrium for the case of time dependent external background or finite integration time

to be applicable to the case when energy conservation law is formally violated.
The assembly of the microtubule-based spindle structure in plant meiosis remains poorly understood compared with our knowledge of mitotic spindle formation. One of the approaches in our understanding of microtubule dynamics is to study spindle assembly in meiosis of amphyhaploids.

Using immunostaining with phH3Ser10, CENH3 and α-tubulin-specific antibodies, we studied the chromosome distribution and spindle organisation in meiosis of F 1 2R(2D)xR wheat-rye hybrids (genome structure ABDR, 4× = 28), as well as in wheat and rye mitosis and meiosis.

Thus, we can conclude that: (1) cohesion maintenance in centromeres and between arms of sister chromatids may negatively affect bipolar spindle formation in the first meiosis; (2) 2R/2D rye/wheat chromosome substitution affects the regulation of the random chromosome distribution in the absence of a bipolar spindle.
The role of beamstrahlung in high-energy e(+)e(-) storage-ring colliders (SRCs) is examined. Particle loss due to the emission of single energetic beamstrahlung photons is shown to impose a fundamental limit on SRC luminosities at energies 2E(0)≳140 GeV for head-on collisions and 2E(0)≳40 GeV for crab-waist collisions. With beamstrahlung taken into account, we explore the viability of SRCs in the 2E(0)=240-500 GeV range, which is of interest in the precision study of the Higgs boson. At 2E(0)=240 GeV, SRCs are found to be competitive with linear colliders; however, at 2E(0)=400-500 GeV, the attainable SRC luminosity would be a factor 15-25 smaller than desired.
Observations of gamma rays up to several 100 TeV are particularly important to spectrally resolve the cutoff regime of the long-sought Pevatrons, the cosmic-ray PeV accelerators.

One component of the TAIGA hybrid detector is the TAIGA-HiSCORE timing array, which currently consists of 28 wide angle (0.6 sr) air Cherenkov timing stations distributed on an area of 0.25 km2. The HiSCORE concept is based on (non-imaging) air shower front sampling with Cherenkov light.

First results are presented.
V. G. Bardakov, Yu. A. Mikhalchishina and M. V. Neshchadim proposed a representation φM of the virtual braid group V Bn into the automorphism group of a free product of a free group and a free Abelian group.

We propose a representation of the virtual braid group V Bn into the automorphism group of a free product of a free groups and a free Abelian groups. Our representation generalizes this representation φM.

It is proved that the kernel of new representation is contained in the kernel of representation φM. It is proved that natural genetic code of image of the virtual braid group V Bn with respect to new representation has strong symmetry.

The accurate simulation of additional interactions at the ATLAS experiment for the analysis of proton–proton collisions delivered by the Large Hadron Collider presents a significant challenge to the computing resources. During the LHC Run 2 (2015–2018), there were up to 70 inelastic interactions per bunch crossing, which need to be accounted for in Monte Carlo (MC) production. In this document, a new method to account for these additional interactions in the simulation chain is described. Instead of sampling the inelastic interactions and adding their energy deposits to a hard-scatter interaction one-by-one, the inelastic interactions are presampled, independent of the hard scatter, and stored as combined events. Consequently, for each hard-scatter interaction, only one such presampled event needs to be added as part of the simulation chain. For the Run 2 simulation chain, with an average of 35 interactions per bunch crossing, this new method provides a substantial reduction in MC production CPU needs of around 20%, while reproducing the properties of the reconstructed quantities relevant for physics analyses with good accuracy.
The role of structure-energy properties of the mechanically induced defects of the crystal structure of heterogeneous catalysts is considered here.

Objectives To determine the gender differences in the effect of sleep disorders on risk of myocardial infarction (MI) and stroke in population 25-64 years over 16 years of follow-up. Methods Under the third screening of WHO program MONICA -Psychosocial a random representative sample of both gender aged 25- 64 years in Novosibirsk was examined in 1994 (n = 1346, male 48.8%, mean age 44,9 ± 0,4 years). The sleep assessment was performed using the Jenkins Sleep Questionnaire. There were 15 cases of new-onset MI in women and 30 in men, new-onset stroke 35 cases in women and 22 in men from 1994 to 2010. Results In an open population aged 25-64 years 48.6% of men and 65.9% of women had sleep disorders (p&lt; 0.001). Univariate analysis showed 2.4-fold risk of MI in those males with SD over 16-year of follow-up (95%CI 1.1-5.3; p&lt; 0.05) but not for women. MI risk was higher in those men who were never married, divorced or widowed (p for all &lt;0.01) compared to married ones. Risk of stroke was higher in men HR = 3 (95%CI 1.2-7.6;p &lt; 0.05) than in women HR = 1.9 (95%CI 1.03-3.7; p &lt; 0.05). Multivariate analysis revealed 2.8-fold risk of stroke (95%CI 1.1-7.1; p &lt; 0.05) in men and HR = 2.7 in women (95%CI 1.4-5.42;p &lt; 0.01) with SD. Stroke risk was higher in men with lower educational level and in women with college degree in those with SD. Conclusions Sleep disorders is a risk factor of MI in men only and stroke for both gender and negative social gradient increases cardiovascular risk.
Long-lived spin states of hyperpolarized propane-d6 gas were demonstrated following pairwise addition of parahydrogen gas to propene-d6 using heterogeneous parahydrogen-induced polarization (HET-PHIP). Hyperpolarized molecules were synthesized using Rh/TiO2 solid catalyst with 1.6 nm Rh nanoparticles. Hyperpolarized (PH ∼ 1%) propane-d6 was detected at high magnetic field (9.4 T) spectroscopically and by high-resolution 3D gradient-echo MRI (4.7 T) as the gas flowed through the radiofrequency coil with a spatial and temporal resolution of 0.5 × 0.5 × 0.5 mm3 and 17.7 s, respectively. Stopped-flow hyperpolarized propane-d6 gas was also detected at 0.0475 T with an observed nuclear spin polarization of PH ∼ 0.1% and a relatively long lifetime with T1,eff = 6.0 ± 0.3 s. Importantly, it was shown that the hyperpolarized protons of the deuterated product obtained via pairwise parahydrogen addition could be detected directly at low magnetic field. Importantly, the relatively long low-field T1,eff of HP propane-d6 gas is not susceptible to paramagnetic impurities as tested by exposure to ∼0.2 atm oxygen. This long lifetime and nontoxic nature of propane gas could be useful for bioimaging applications including potentially pulmonary low-field MRI. The feasibility of high-resolution low-field 2D gradient-echo MRI was demonstrated with 0.88 × 0.88 mm2 spatial and ∼0.7 s temporal resolution, respectively, at 0.0475 T.

Main results obtained in this field with the Belle detector as well as perspectives of the new experiments with the Belle II detector at the SuperKEKB collider is discussed in this report.
Localized electric fields induce diamond crystallization from carbonates under P - T conditions of Earth's mantle
We consider a model nondispersive nonlinear optical fiber channel with an additive Gaussian noise.

Using Feynman path-integral technique, we find the optimal input signal distribution maximizing the channel's per-sample mutual information at large signal-to-noise ratio in the intermediate power range. We calculate the output signal entropy, conditional entropy, and per-sample mutual information for Gaussian, half-Gaussian, and modified Gaussian input signal distributions.

The optimal input signal distribution allows us to improve previously known estimates for the channel capacity. We demonstrate that in the intermediate power range the capacity (the per-sample mutual information for the optimal input signal distribution) is greater than the per-sample mutual information for half-Gaussian input signal distribution considered previously as the optimal one. We also show that the capacity grows as $loglogP$ in the intermediate power range, where $P$ is the signal power.
Acute cerebral ischemia induces distant inflammation in the hippocampus; however, molecular mechanisms of this phenomenon remain obscure. Here, hippocampal gene expression profiles were compared in two experimental paradigms in rats: middle cerebral artery occlusion (MCAO) and intracerebral administration of lipopolysaccharide (LPS). The main finding is that 10 genes (Clec5a, CD14, Fgr, Hck, Anxa1, Lgals3, Irf1, Lbp, Ptx3, Serping1) may represent key molecular links underlying acute activation of immune cells in the hippocampus in response to experimental ischemia. Functional annotation clustering revealed that these genes built the same clusters related to innate immunity/immunity/innate immune response in all MCAO differentially expressed genes and responded to the direct pro-inflammatory stimulus group. The gene ontology enrichment and Kyoto Encyclopedia of Genes and Genomes pathway analyses also indicate that LPS-responding genes were the most abundant among the genes related to "positive regulation of tumor necrosis factor biosynthetic process", "cell adhesion", "TNF signaling pathway", and "phagosome" as compared with non-responding ones. In contrast, positive and negative "regulation of cell proliferation" and "HIF-1 signaling pathway" mostly enriched with genes that did not respond to LPS. These results contribute to understanding genomic mechanisms of the impact of immune/inflammatory activation on expression of hippocampal genes after focal brain ischemia.
A cyclic creep damage model, previously proposed by the authors, is modified for a better description of the transient creep of D16T alloy observed in the finite strain range under rapidly changing stresses.

The new model encompasses the concept of kinematic hardening, which allows us to account for the creep-induced anisotropy. The model kinematics is based on the nested multiplicative split of the deformation gradient, proposed by Lion. The damage evolution is accounted for by the classical Kachanov-Rabotnov approach. The material parameters are identified using experimental data on cyclic torsion of thick-walled samples with different holding times between load reversals.

For the validation of the proposed material model, an additional experiment is analyzed. Although this additional test is not involved in the identification procedure, the proposed cyclic creep damage model describes it accurately.
G-banding was successfully demonstrated in chromosomes of Baicalasellus angarensis (Isopoda, Crustacea) using a simple and reproducible technique. The obtained bands were numerous and distributed along the whole length of the chromosomes. The number of the G-bands mached interrelated with the condensation of chromosomes. The bands of homologous chromosomes in some cells were matchable. C-banding patterns in chromosomes of B. angarensis have also been investigated.

The constitutive heterochromatin is located in centromeric and interstitial position of several chromosomes.
In this study, we used ELISA for quantification of PPDK in photosynthesizing leaves of miscanthus. We cloned a fragment of the gene encoding PPDK, purified the resulting protein by affinity chromatography, identified it using MALDI mass spectrometry, and obtained monoclonal antibodies by immunizing BALB/c mice. Selectivity of monoclonal antibodies was assessed by Western blot using the protein extracts of Soranovskii. The presence of PPDK was again verified by MALDI mass spectrometry. Therefore, we developed and tested the method for determining PPDK quantity in miscanthus using ELISA.
Used the set-up with a semi-circular gap allows the realization of different types of Couette flow and to change the flow parameters (velocity, pressure, Reynolds and Knudsen numbers, etc.) over a wide range. Reynolds number can be varied by the cylinder rotation speed and pressure inside the facility. Obtaining high Knudsen numbers is possible at low pressures and using light gases, since the system is sealed.

Simulation of the properties of the flat Couette flow in the stand should be ensured by minimizing the influence on the flow of centrifugal forces, which are manifested by distortion of the linear velocity profile.

The nature of the flow varies from laminar to turbulent ones. Preliminary experiments have shown the possibility of modeling the formation of longitudinal vortices in a semi-circular channel similar to the circular Couette flow.
The variants of two- and three-dimensional lattice Boltzmann methods (LBM) are described for computer simulations of fluids with liquid-vapor phase transitions and heat transfer. Several improvements of LBM are described (correct implementation of the body force term, "pseudoforces" for the method of "passive scalar" for internal energy and implementation of a latent heat of evaporation). The formation of rivulets in a flow along an inclined flat surface, the fall of a droplet onto a rigid nonwettable plane and the process of spinodal decomposition of initially uniform fluid are modelled.
