The measurement assumes no direct CP violation in B0→D(*)h0 decays. The quoted model uncertainties are due to the composition of the D0→K0Sπ+π− decay amplitude model, which is newly established by performing a Dalitz plot amplitude analysis using a high-statistics e+e−→c¯c data sample.

The measurement is performed combining the final data sets of the BABAR and Belle experiments collected at the Υ(4S) resonance at the asymmetric-energy B factories PEP-II at SLAC and KEKB at KEK, respectively. The data samples contain (471±3)×106B¯B pairs recorded by the BABAR detector and (772±11)×106B¯B pairs recorded by the Belle detector. Using a time-dependent Dalitz plot analysis of B0→D(*)h0 with D→K0Sπ+π− decays, where h0∈{π0,η,ω} denotes a light unflavored and neutral hadron.

We present first evidence that the cosine of the CP-violating weak phase 2β is positive, and hence exclude trigonometric multifold solutions of the Cabibbo-Kobayashi-Maskawa (CKM) Unitarity Triangle. The results of the measurement are sin2β=0.80±0.14(stat)±0.06(syst)±0.03(model) and cos2β=0.91±0.22(stat)±0.09(syst)±0.07(model). The result for the direct measurement of the angle β of the CKM Unitarity Triangle is β=[22.5±4.4(stat)±1.2(syst)±0.6(model)]°. CP violation is observed in B0→D(*)h0 decays at the level of 5.1 standard deviations. The significance for cos2β>0 is 3.7 standard deviations. The trigonometric multifold solution π/2−β=(68.1±0.7)° is excluded at the level of 7.3 standard deviations. The measurement resolves an ambiguity in the determination of the apex of the CKM Unitarity Triangle.
The decays ${D}^{0}\ensuremath{\rightarrow}d\overline{u}{e}^{+}\ensuremath{\nu}\ensuremath{\rightarrow}{a}_{0}^{\ensuremath{-}}(980){e}^{+}\ensuremath{\nu}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}\ensuremath{\eta}{e}^{+}\ensuremath{\nu}$ and ${D}^{+}\ensuremath{\rightarrow}d\overline{d}{e}^{+}\ensuremath{\nu}\ensuremath{\rightarrow}{a}_{0}^{0}(980){e}^{+}\ensuremath{\nu}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}\ensuremath{\eta}{e}^{+}\ensuremath{\nu}$ (and the charge conjugated ones) are the direct probe of the constituent two-quark components in the ${a}_{0}^{\ifmmode\pm\else\textpm\fi{}}(980)$ and ${a}_{0}^{0}(980)$ wave functions.

The recent BESIII experiment is the first step in the experimental study of these decays. We suggest adequate formulas for the data analysis and present a variant of $\ensuremath{\eta}\ensuremath{\pi}$ invariant mass distribution

when ${a}_{0}(980)$ has no constituent two-quark component at all.
In December 2019, the first cases of pneumonia of unknown etiology were found in Wuhan (China). Later, the pneumonia was associated with a new coronavirus; in February 2020, the World Health Organization (WHO) gave the name COVID-19 to the new disease, while the International Committee on Taxonomy of Viruses (ICTV) gave the name SARS-CoV-2 to the virus causing it. By March 11, 2020, when the virus had spread to 114 countries, the number of diagnosed patients had reached 118 thousand and the number of deaths was 4000, the WHO declared the outbreak of the disease a pandemic. In this review, we summarize the relevant information about the origin and spread of SARS-CoV-2, its epidemiology and diagnostics, and the clinical course and treatment of COVID-19.
A model of a hypersonic air intake based on the principle of compression along the directions of the captured jet converging in space is studied. Such an air intake allows a high compression ratio and a compact section of the internal channel, which simplifies the heat protection of the air intake and the combustion chamber. Experimental studies were carried out in a pulsed wind tunnel IT-302M for Mach number M = 6 - 8 in the range of angles of attack from 0° to 8°. Numerical simulation has been performed based on solving the full averaged Navier-Stokes equations, supplemented k-w turbulence model. The pressure distributions on the compression surfaces and in the air intake channel are obtained, the coefficients of the total pressure recovery and flow rate, the Mach number in the throat of the air intake are determined. The features of the flow structure for three variants of the air intake in the area of external compression are established: with side walls, side walls with slots and without side walls. The influence of the boundary layer bleed and lateral spreading on the launch and integral characteristics of a hypersonic air intake with a compact cross-section of the inner channel is determined. Satisfactory agreement between the calculated and experimental data is shown.
The data were recorded with the BABAR detector at center-of-mass energies at and near the ϒ(4S) resonance, and correspond to an integrated luminosity of approximately 468 fb^{-1}.

We measure the mass difference, Δm_{+}, between the D^{*}(2010)^{+} and the D^{+} using the decay chain D^{*}(2010)^{+}→D^{+}π^{0} with D^{+}→K^{-}π^{+}π^{+}.

We measure Δm_{+}=(140 601.0±6.8[stat]±12.9[syst]) keV. We combine this result with a previous BABAR measurement of Δm_{0}≡m(D^{*}(2010)^{+})-m(D^{0}) to obtain Δm_{D}=m(D^{+})-m(D^{0})=(4824.9±6.8[stat]±12.9[syst]) keV. These results are compatible with and approximately five times more precise than the Particle Data Group averages.
The article describes the results of exploration works in the lower reaches of the Ob (Shuryshkarsky district of the YNAO) in 2021. The coastline of the right bank of the Ob was studied in three main areas: near the villages of Khashgort, Kushevat and the Sormas channel.

In total, 13 pits and 2 excavation trenches were made with a total area of 70 sq. m. The coastline near the village of Khashgort revealed paleofaunal materials and stone artifacts of the Paleolithic type. The main excavations were carried out at the Kushevat Paleolithic site discovered in 2020. Archaeological and paleofaunal materials were recorded in the alluvial deposits of two excavation trenches with a total area of 44 sq.m at an unnamed inflow of the Ob. The excavations revealed tree bone-bearing layers; stone artifacts, charcoal pieces, and non-utilitarian items were recovered from the lowermost layer. Archaeological materials (2 specimens) are represented by a small spall and an exhausted core of the parallel reduction pattern. The paleofaunal material numbering 110 units (bones, horns, teeth, and fragments) is mainly represented by the remains of a reindeer.

Thus, in the field season of 2021, a new locus of the surface occurrence of the Paleolithic materials was identified supporting previous identification of a cultural layer at Kushevat. As a result, taking into account the stratigraphic situation at the site and the preliminary results of radiocarbon dating, the Kushevat site is currently the northernmost and most ancient of the known Paleolithic sites known in the Ob valley. Apparently, the derived data indicate the earliest, pioneering stage of Homo sapiens sapiens habitation of the subarctic zone during MIS3 in the range of 45-30 ka BP.
Simulation of a blood flow under normality as well as under pathology is extremely complex problem of great current interest both from the point of view of fundamental hydrodynamics, and for medical applications. This paper proposes a model of Van der Pol - Duffing nonlinear oscillator equation describing relaxation oscillations of a blood flow in the cerebral vessels. The model is based on the patient-specific clinical experimental data flow obtained during the neurosurgical operations in Meshalkin Novosibirsk Research Institute of Circulation Pathology. The stability of the model is demonstrated through the variations of initial data and coefficients. It is universal and describes pressure and velocity fluctuations in different cerebral vessels (arteries, veins, sinuses), as well as in a laboratory model of carotid bifurcation. Derived equation describes the rheology of the "blood stream - elastic vessel wall gelatinous brain environment" composite system and represents the state equation of this complex environment.
In the work presented, the polymer-graphene-gold composites obtained by the methods of chemical vapor deposition and pulsed laser ablation (PLA) are studied. The morphological and optical properties of the given samples are studied in detail. It is shown that with an increase in the number of laser pulses in the PLA method, the metal coating transforms from separate small gold particles to a continuous cover with the presence of large nanoparticles. It is shown that a change in the gold film thickness influences significantly the efficiency of plasmon attenuation of a signal: with an increase in the average mass thickness, the effect increases and reaches its maximal value at film thickness of 6 nm. It is shown that the most intense plasmon absorption occurs in the wavelength range from 550 to 750 nm. A further increase in the thickness of metal coating decreases sample transparency in the studied range and does not affect the intensity of plasmon absorption and scattering.
Отмечается неуклонный рост количества пациентов, имеющих очаговые образования печени, Гемангиомы и кисты являются самыми частыми находками среди них.

Нами обследован 61 пациент с очаговыми образованиями печени, большинство поражений протекают бессимптомно, что снижает вероятность их обнаружения на раннем этапе и не имеют специфических лабораторных отклонений, что затрудняет дифференциальную диагностику выявленных образований.

The work continues a series of articles devoted to the peculiarities of solving coefficient inverse problems for nonlinear singularly perturbed equations of the reaction-diffusion-advection-type with data on the position of the reaction front. In this paper, we place the emphasis on some problems of the numerical solving process. One of the approaches to solving inverse problems of the class under consideration is the use of methods of asymptotic analysis. These methods, under certain conditions, make it possible to construct the so-called reduced formulation of the inverse problem. Usually, a differential equation in this formulation has a lower dimension/order with respect to the differential equation, which is included in the full statement of the inverse problem. In this paper, we consider an example that leads to a reduced formulation of the problem, the solving of which is no less a time-consuming procedure in comparison with the numerical solving of the problem in the full statement. In particular, to obtain an approximate numerical solution, one has to use the methods of the numerical diagnostics of the solution’s blow-up. Thus, it is demonstrated that the possibility of constructing a reduced formulation of the inverse problem does not guarantee its more efficient solving. Moreover, the possibility of constructing a reduced formulation of the problem does not guarantee the existence of an approximate solution that is qualitatively comparable to the true one. In previous works of the authors, it was shown that an acceptable approximate solution can be obtained only for sufficiently small values of the singular parameter included in the full statement of the problem. However, the question of how to proceed if the singular parameter is not small enough remains open. The work also gives an answer to this question.
ATM (ataxia-telangiectasia mutated) is a central molecule for DNA quality control. Its activation by DNA damage promotes cell-cycle delay, which facilitates DNA repair prior to replication. On the other hand, persistent DNA damage has been implicated in ATM-dependent cell death via apoptosis; however, the mechanisms underlying this process remain elusive.

Here we find that, in response to persistent DNA strand breaks, ATM phosphorylates transcription factor Sp1 and initiates its degradation. We show that Sp1 controls expression of the key base excision repair gene XRCC1, essential for DNA strand break repair.

Therefore, degradation of Sp1 leads to a vicious cycle that involves suppression of DNA repair and further aggravation of the load of DNA damage. This activates transcription of pro-apoptotic genes and renders cells susceptible to elimination via both apoptosis and natural killer cells. These findings constitute a previously unrecognized 'gatekeeper' function of ATM as a detector of cells with persistent DNA damage.

When creating geoinformation systems of a city scale, relation this or that information from Internet, there comes the task of creation an ontology of urbanonyms taking into account their historical changes. The account of historical changes is necessary, for example, to process messages about urban event from blogs: since more and more representatives of the middle and older generations are becoming active Internet users, the massages often contain the former names of urbanonyms. Let us note that it is the accounting of historical changes that is required to solve this problem that determines the need to create not a thesaurus, which is sufficient, as shown in [1], to take into account geographical names commonly used (at least in natural science articles) in their actual from, but an ontology. Taking into account the specifics of the task of creating an ontology of Almaty, in should be bilingual: in the Kazakh and Russian languages.

This study examines the benefit of using Ocean Mean Temperature (OMT) to aid in the prediction of the sign of Indian Summer Monsoon Rainfall (ISMR) anomalies. This is a statistical examination, rather than a process study. The thermal energy needed for maintaining and intensifying hurricanes and monsoons comes from the upper ocean, not just from the thin layer represented by sea surface temperature (SST) alone. Here, we show that the southwestern Indian OMT down to the depth of the 26 °C isotherm during January–March is a better qualitative predictor of the ISMR than SST. The success rate in predicting above- or below-average ISMR is 80% for OMT compared to 60% for SST. Other January–March mean climate indices (e.g., NINO3.4, Indian Ocean Dipole Mode Index, El Niño Southern Oscillation Modoki Index) have less predictability (52%, 48%, and 56%, respectively) than OMT percentage deviation (PD) (80%). Thus, OMT PD in the southwestern Indian Ocean provides a better qualitative prediction of ISMR by the end of March and indicates whether the ISMR will be above or below the climatological mean value.
This paper reviews results about discrete physics and non-commutative worlds

explores further the structure and consequences of constraints linking classical calculus and discrete calculus formulated via commutators. In particular, we review how the formalism of generalized non-commutative electromagnetism follows from a first order constraint and how, via the Kilmister equation, relationships with general relativity follow from a second order constraint.

It is remarkable that a second order constraint, based on interlacing the commutative and non-commutative worlds, leads to an equivalent tensor equation at the pole of geodesic coordinates for general relativity.
BTF is a peculiar high explosive which is completely hydrogen-free: its molecular formula is C 6 N 6 O 6 . Results are compared with the conductivity distributions in detonating hexogen (RDX, C 3 H 6 N 6 O 6 ) and triaminotrinitrobenzene based explosive (TATB, C 6 H 6 N 6 O 6 ).

Electrical conductivity profile behind the detonation front in the benzotrifuroxane (BTF) was measured using high-resolution technique.

The conductivity in BTF was found to be similar to that observed in the common explosives which contain hydrogen. Thus, the contribution of hydrogen (e.g., ions produced by the dissociation of water) in the conductivity is minor, both in the reaction zone and in the final detonation products. The characteristics of the conductivity profiles generally support the idea of contact conductivity through the connected structures of carbon particles formed in the detonation wave.
In this work, a possibility of using hydraulic fracturing proppants (HFP) as supports for deep oxidation catalysts, employed in the fluidized bed catalytic combustion, was considered.

Two methods based on leaching with alkali solution were used to increase a specific surface area of HFP.The samples were characterized by physico-chemical methods (XPS, XRD, low-temperature nitrogen adsorption).CuCrcontaining catalysts, based on HFP and obtained by the wet-impregnation method, and industrial catalysts were tested in the process of combustion brown coal in fluidized bed.

It was shown that catalysts based on HFP allow us to reach a high degree of burnout (95%) which typical for industrial catalysts and higher than in the case when using an inert material (70%).

The aim of the study was to determine the levels of depression and life exhaustion in men and women of the open urban population in the age range. Materials and methods. A single-stage epidemiological study was conducted among people of both sexes aged 25-64 in Tyumen. A representative sample was formed from the electoral lists of citizens by the method of "random numbers" - 2000 men and women with a response among men 85.0%, among women - 70.3%. The study of depression was conducted according to the algorithms of the program of the world health organization "MONICA-psychosocial". Results. The prevalence of depression in the Tyumen population and in the age and sex groups showed a predominance of the average level over the high, in the age categories 25-34 and 35-44 years - significantly higher prevalence of high levels of depression in women. The higher prevalence of the average level of men and women IN the open population was determined to be relatively high. The average level of LIFE significantly prevails in women in the older age categories and in the population as a whole, the high level of LIFE - at the age of 25-34 years in women and at the age of 55-64 years in men. Conclusion. Therefore, in the open population of the middle-urbanized Siberian city there is a need to form an integrated approach to the prevention of non-infectious diseases, especially cardiovascular diseases, as it is established that prevention programs lead to a reduction in the burden of depression and, and effective approaches to the prevention of psycho-emotional States at the level of individual communities include school-oriented programs to teach positive thinking among the population, starting from a young age.

Computational modeling based on data on the compositions of melt inclusions in chrome-spinelids using the COMAGMAT [12] and PETROLOG [11] programs indicates the similarity of the parent melt of meimechites [4] with the picritic magma of the Gulinsky massif. Experimental data on the inclusions confirm this conclusion, showing the reliability of the actually calculated trends in the fractionation of ultrabasic melts. In general, the calculations showed that the crystallization of olivine from the high-magnesium pyrite melt occurred in the temperature range of 1510–1260 ° C, mainly at a pressure of 6–7 kbar. At the same time, the melt evolves and approaches its composition to olivine basalt, from which, starting from 1200 ° C, clinopyroxene mainly crystallizes with enrichment of the residual melt with alkalis, rare and rare-earth elements. The similarity of the compositions of the parental melts for meimechites and Gulinsky pluton rocks and the proximity of P – T parameters of their evolution indicates a possible genetic relationship of these magmatic formations.
A fully developed turbulent air flow at constant Reynolds number Re = 5300 is injected to space, filled with air, carbon dioxide or helium with a small co-flow, with variable density being due to the mixing of different gases.
