From a Dalitz plot analysis of $B\ensuremath{\rightarrow}K{\ensuremath{\pi}}^{+}{\ensuremath{\psi}}^{\ensuremath{'}}$ decays, we find a signal for $Z(4430{)}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\psi}}^{\ensuremath{'}}$ with a mass $M=({4443}_{\ensuremath{-}12\ensuremath{-}13}^{+15+19})\text{ }\text{ }\mathrm{MeV}/{c}^{2}$, width $\ensuremath{\Gamma}=({107}_{\ensuremath{-}43\ensuremath{-}56}^{+86+74})\text{ }\text{ }\mathrm{MeV}$, product branching fraction $\mathcal{B}({\overline{B}}^{0}\ensuremath{\rightarrow}{K}^{\ensuremath{-}}Z(4430{)}^{+})\ifmmode\times\else\texttimes\fi{}\mathcal{B}(Z(4430{)}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\psi}}^{\ensuremath{'}})=({3.2}_{\ensuremath{-}0.9\ensuremath{-}1.6}^{+1.8+5.3})\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$, and significance of $6.4\ensuremath{\sigma}$ that agrees with previous Belle measurements based on the same data sample.

These results are obtained from a $605\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ data sample that contains $657\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ pairs collected near the $\ensuremath{\Upsilon}(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider.

In addition, we determine the branching fraction $\mathcal{B}({B}^{0}\ensuremath{\rightarrow}{K}^{*}(892{)}^{0}{\ensuremath{\psi}}^{\ensuremath{'}})=({5.52}_{\ensuremath{-}0.32\ensuremath{-}0.58}^{+0.35+0.53})\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ and the fraction of ${K}^{*}(892{)}^{0}$ mesons that are longitudinally polarized ${f}_{L}=({44.8}_{\ensuremath{-}2.7\ensuremath{-}5.3}^{+4.0+4.0})%$.
Reliable recognition of the promoters in eukaryotic genomes remains an open issue. This is largely owing to the poor understanding of the features of the structural-functional organization of the eukaryotic promoters essential for their function and recognition. However, it was demonstrated that detection of ensembles of regulatory signals characteristic of specific promoter groups increases the accuracy of promoter recognition and prediction of specific expression features of the queried genes. The ARGO_Motifs package was developed for the detection of sets of region-specific degenerate oligonucleotide motifs in the regulatory regions of the eukaryotic genes. The ARGO_Viewer package was developed for the recognition of tissue-specific gene promoters based on the presence and distribution of oligonucleotide motifs obtained by the ARGO_Motifs program. Analysis and recognition of tissue-specific promoters in five gene samples demonstrated high quality of promoter recognition. The public version of the ARGO system is available at http://wwwmgs2.bionet.nsc.ru/argo/ and http://emj-pc.ics.uci.edu/argo/.
The nuclear envelope (NE) is a fundamental structure of eukaryotic cells with a dual role: it separates two distinct compartments, and enables communication between them via nuclear pore complexes (NPCs). Little is known about NPCs and NE structural organization in plants.

We investigated the structure of NPCs from both sides of the NE in tobacco BY-2 cells.

We detected structural differences between the NPCs of dividing and quiescent nuclei. Importantly, we also traced the organizational pattern of the NPCs, and observed non-random NPC distribution over the nuclear surface. Lastly, we observed an organized filamentous protein structure that underlies the inner nuclear membrane, and interconnects NPCs. The results are discussed within the context of the current understanding of NE structure and function in higher eukaryotes.
Breeding group includes four genealogical lines of boars united by a successive father-son relationship. Three lines: MS2853, MS2987, and VTN300 inherited their Y chromosomes from boars of Vietnamese-South Asian breed. The fourth line (LNDR07) received Y chromosome from the Landrace boar.

This paper describes the results of the influence of Y-chromosome gene complex on pre- and postnatal growth of piglets of laboratory mini-pigs ICG SB RAS.

This study revealed that all three lines of boars carrying Asian Y chromosome did not differ in weight of newborn offspring, while the weight and, correspondingly, prenatal growth of newborns of boars carrying European Y chromosome were statistically significantly less. Thus, at this stage of research, there is reason to believe that the selection group of mini-pigs ICG SB RAS contains polymorphism in the complex of Y-chromosome genes involved in the control of prenatal growth process. An assumption was considered that growth retardation during prenatal and early postnatal periods, as well as an increased proportion of culled offspring of boars carrying European Y chromosome can be caused by poor compatibility of its gene complex with the allele pool inherited from the mini pigs ICG SB RAS from Vietnamese breed.
Thermal decomposition of complex salts [M(NH3)4]A (M = Pt, Pd; A = CrO4, Cr2O7) in oxygen atmosphere goes through the stage of formation of the phase MCrO2 with delafossite structure and it's further decomposition and formation of the chromium oxide(III) and monometallic platinum or palladium.

Thermal decomposition of complex salts [M(NH3)4]A (M = Pt, Pd; A = CrO4, Cr2O7) in hydrogen atmosphere proceeds with partial reduction of chromium to an metallic state and the formation of a metal solid solution MxCr1-x (M = Pt, Pd) with a chromium content up to 22 at.% and a chromium oxide(III).

Catalytic properties of bimetallic Pt-Cr2O3 and Pd-Cr2O3 composites obtained by thermal decomposition in hydrogen atmosphere at the temperature 500 °C differs a lot from monometallic Pt and Pd in CO TOX and PROX processes.Addition of Cr2O3 boosted oxidative activity of metals probably due to appearance of metal-oxide interface, which is of crucial importance in catalysis.

Hihg-power flows of plasma cause mechanical destruction of materials via non-uniform deformation and stresses. The possibility of synchrotron radiation scattering diagnostics of deformation is discussed. The experiments at the new scattering station "Plasma" on VEPP-4M demonstrated the measurements of change in the diffraction angle during pulsed heating.
Till yet there is no data concerning mechanisms of autoimmune diseases development. Experimental autoimmune encephalomyelitis (EAE) prone C57BL/6 (T- and B-lymphocyte response), non-autoimmune CBA, and Th mice with T cell response were immunized with myelin oligodendrocyte glycoprotein (MOG35–55) to compare different characteristics of autoimmune reaction development. Bone marrow differentiation profiles of hematopoietic stem cells (HSCs), lymphocyte proliferation in various organs associated with the production of antibodies against DNA, myelin basic protein (MBP), and MOG, as well as abzymes hydrolyzing these antigens, were analyzed before and after immunization. Profiles of HSC differentiation [BFU-E (erythroid burst-forming unit (early erythroid colonies), CFU-E (erythroid burst-forming unit (late erythroid colonies), CFU-GM (granulocytic-macrophagic colony-forming unit), and CFU-GEMM granulocytic-erythroid-megakaryocytic-macrophagic colony-forming unit] and patterns of lymphocyte proliferation in different organs (brain, spleen, thymus, and lymph nodes) were very different for C57BL/6, CBA, and Th mice. We conclude that only C57BL/6 mice were predisposed to spontaneous and MOG-induced acceleration of EAE development. CBA mice are not prone to the development of autoimmune reactions. After immunization, Th mice demonstrate changes in several parameters similar to C57BL/6 and other to CBA mice; Th mice are more prone to developing autoimmune reactions than CBA mice. Our data may be important for understanding the combined presence in mice lymphocytes with T and B cell responses for spontaneous and induced autoimmune diseases.
The development of efficient and convenient systems for the delivery of nucleic-acid-based drugs into cells is an urgent task. А promising approach is the use of various nanoparticles. Silica nanoparticles can be used as vehicles to deliver nucleic acid fragments into cells. In this work, we developed a method for the synthesis of silicon–organic (Si–NH 2 ) non-agglomerated nanoparticles by the hydrolysis of aminopropyltriethoxysilane (APTES). The resulting product forms a clear solution containing nanoparticles in the form of low molecular weight polymer chains with [─Si(OH)(C 3 H 6 NH 2 )O─] monomer units. Oligonucleotides (ODN) were conjugated to the prepared Si–NH 2 nanoparticles using the electrostatic interaction between positively charged amino groups of nanoparticles and negatively charged internucleotide phosphate groups in oligonucleotides. The Si–NH 2 nanoparticles and Si–NH 2 ·ODN nanocomplexes were characterized by transmission electron microscopy, atomic force microscopy and IR and electron spectroscopy. The size and zeta potential values of the prepared nanoparticles and nanocomplexes were evaluated. Oligonucleotides in Si–NH 2 ·ODN complexes retain their ability to form complementary duplexes. The Si–NH 2 Flu nanoparticles and Si–NH 2 ·ODN Flu nanocomplexes were shown by fluorescence microscopy to penetrate into human cells. The Si–NH 2 Flu nanoparticles predominantly accumulated in the cytoplasm whereas ODN Flu complexes were predominantly detected in the cellular nuclei. The Si–NH 2 ·ODN nanocomplexes demonstrated a high antisense activity against the influenza A virus in a cell culture at a concentration that was lower than their 50% toxic concentration by three orders of magnitude.
Sporadic Alzheimer’s disease (AD) is a severe disorder of unknown etiology with no definite time frame of onset. Recent studies suggest that middle age is a critical period for the relevant pathological processes of AD. Nonetheless, sufficient data have accumulated supporting the hypothesis of “neurodevelopmental origin of neurodegenerative disorders”: prerequisites for neurodegeneration may occur during early brain development. Therefore, we investigated the development of the most AD-affected brain structures (hippocampus and prefrontal cortex) using an immunohistochemical approach in senescence-accelerated OXYS rats, which are considered a suitable model of the most common—sporadic—type of AD. We noticed an additional peak of neurogenesis, which coincides in time with the peak of apoptosis in the hippocampus of OXYS rats on postnatal day three. Besides, we showed signs of delayed migration of neurons to the prefrontal cortex as well as disturbances in astrocytic and microglial support of the hippocampus and prefrontal cortex during the first postnatal week. Altogether, our results point to dysmaturation during early development of the brain—especially insufficient glial support—as a possible “first hit” leading to neurodegenerative processes and AD pathology manifestation later in life.
Heterochiasmy, a sex-based difference in recombination rate, has been detected in many species of animals and plants. Several hypotheses about evolutionary causes of heterochiasmy were proposed. However, there is a shortage of empirical data.

In this paper, we compared recombination related traits in females and males of the barn swallow Hirundo rustica (Linnaeus, 1758), the species under strong sexual selection, with those in the pale martin Riparia diluta (Sharpe and Wyatt, 1893), a related and ecologically similar species with the same karyotype (2N = 78), but without obvious sexual dimorphism. Recombination traits were examined in pachytene chromosome spreads prepared from spermatocytes and oocytes. Synaptonemal complexes and mature recombination nodules were visualized with antibodies to SYCP3 and MLH1 proteins, correspondingly.

Recombination rate was significantly higher (p = 0.0001) in barn swallow females (55.6 ± 6.3 recombination nodules per autosomal genome), caused by the higher number of nodules at the macrochromosomes, than in males (49.0 ± 4.5). They also showed more even distribution of recombination nodules along the macrochromosomes. At the same time, in the pale martin, sexual differences in recombination rate and distributions were rather small. We speculate that an elevated recombination rate in the female barn swallows might have evolved as a compensatory reaction to runaway sexual selection in males.
The arrays formation of submicron- and micron-sized SiGe and Ge dielectric particles on the Si and SiO 2 surfaces, which occur due to solid-state dewetting, is investigated. The shape of the particles and their spatial distribution turned out to be strongly dependent on the crystallographic Si surface orientation, the amount of deposited Ge and the Ge deposition rate, as well as on the presence of a SiO 2 film on the Si surface. Possible applications of various surface morphologies with metasurface properties are discussed.
The subject of the study is axisymmetric channel with a hemispherical bottom. The compressed air flows into the channel through the holes located on the surface of the hemispherical bottom. The ratio of all holes area to the outlet area of the channel is equal to 0.25. The experimental and numerical study of jets intersecting at a single point is performed. The countermoving jets and the focused jets are investigated. The distribution of pressure over the surface of the channel and the total pressure at the output of the channel are obtained. The main experimental result is as follows: the total pressure recovery coefficient for the focused jets is twice more than that for the countermoving jets.
The Ortsog-Uul mafic-ultramafic massif of Western Mongolia is located in a tectonic block with overturned bedding.

The massif hosts two intrusions: a rhythmically-layered peridotite-gabbro association (Intrusion 1) and massive Bt-bearing amphibole-olivine gabbro (Intrusion 2). Intrusions 1 and 2 have different petrology features. Early Intrusion 1 (278±2.5Ma) is characterized by lower concentrations of alkalis, titanium and phosphorus than late Intrusion 2 (272±2Ma). The chondrite-normalized REE and primitive mantle-normalized rare elements patterns of Ortsog-Uul intrusions have similar curves of elements distribution. However, Intrusion 2 is characterized higher contents of REE and rare elements. High concentrations of incompatible elements are indicative of strong fractionation process. Model calculations (COMAGMAT-3.57) show that parental melts of two intrusions were close to high-Mg picrobasaltic magmas. The concentration of MgO in melt is 16.21 (Intrusion 1) and 16.17 (Intrusion 2).

It has been suggested that Intrusions 1 and 2 derived from compositionally different parental melts. Isotopic data of Ortsog-Uul magmatic rocks exhibit different values of εNd (positive and negative) for Intrusion 1 and 2, respectively.
Experimental and numerical studies of spatiotemporal femtosecond soliton propagation over up to 1 km spans of parabolic graded-index fibers reveal that initial multimode soliton pulses naturally and irreversibly evolve into a single-mode soliton. This is carried by the fundamental mode of the fiber, which acts as a dynamical attractor of the multimode system for up to the record value (for multimode fibers) of 5600 chromatic dispersion distances. This experimental evidence invalidates the use of variational approaches, which intrinsically require that the initial multimode propagation of a self-imaging soliton is indefinitely maintained.
We establish Luzin N and Morse–Sard properties for functions from the Sobolev space W n , 1 ( ℝ n ) $\mathrm {W}^{n,1}(\mathbb {R}^n)$ .

For the proofs we establish and use some new results on Luzin-type approximation of Sobolev and BV $\mathrm {BV}$ -functions by C k $\mathrm {C}^k$ -functions, where the exceptional sets have small Hausdorff content.

Using these results we prove that almost all level sets are finite disjoint unions of C 1 $\mathrm {C}^1$ -smooth compact manifolds of dimension n - 1. These results remain valid also within the larger space of functions of bounded variation BV n ( ℝ n ) $\mathrm {BV}_n(\mathbb {R}^n)$ .
Self-similar sets with open set condition, the linear objects of fractal geometry, have been considered mainly for crystallographic data.

Here we introduce new symmetry classes in the plane, based on rotation by irrational angles. Examples without characteristic directions, with strong connectedness and small complexity were found in a computer-assisted search. We develop a classification of self-similar sets by symmetry class and algebraic numbers.

They are surprising since the rotations are given by rational matrices, and the proof of the open set condition usually requires integer data. Examples are given for various quadratic number fields.
It is widely believed that Robertsonian rearrangements have played a key role in the chromosome evolution of species of the Sorex araneus group.

We present FISH data relating to the distribution of telomeric repeats and 18S rDNA on the chromosomes of Sorex araneus and Sorex granarius, which have karyotypes with almost identical chromosome arms.All chromosomes in S. araneus (Novosibirsk race) are metacentrics, whereas S. granarius has an acrocentric karyotype with two metacentric exceptions.In FISH experiments we revealed telomeric repeats at the ends of all S. araneus chromosomes but only on the short arms of S. granarius acrocentrics, which, as we have shown earlier, amount up to 300 kb in length.FISH signals of the (TTAGGG)n probe and the probe derived by microdissection of the pericentric regions of S. granarius acrocentrics a and b were co-localised or sequentially localised on distinct chromatin fibres of S. granarius.18S rDNA clusters were found at the ends of short arms of 12 out of 16 S. granarius acrocentric pairs.In S. araneus primary cell culture fibroblasts rDNA was found at the ends of the q, t and u arms.However, after long cultivation of these cells an additional FISH signal of rDNA was found at the distal end of the o arm of chromosome go.In some regions the FISH signal of rDNA coincided with the signal of the telomeric probe.

We suppose that rapid concerted evolution of telomeric and rDNA led to the repatterning of these repetitive DNA fractions in the sibling species S. araneus and S. granarius as well as the formation of large telomeres with unusual structure at the ends of the S. granarius chromosomes.
X chromosome inactivation takes place in the early development of female mammals and depends on the Xist gene expression. The mechanisms of Xist expression regulation have not been well understood so far. In this work, we compared Xist promoter region of vole Microtus rossiaemeridionalis and other mammalian species. We observed three conserved regions which were characterized by computational analysis, DNaseI in vitro footprinting, and reporter construct assay. Regulatory factors potentially involved in Xist activation and repression in voles were determined. The role of CpG methylation in vole Xist expression regulation was established. A CTCF binding site was found in the 5′ flanking region of the Xist promoter on the active X chromosome in both males and females. We suggest that CTCF acts as an insulator which defines an inactive Xist domain on the active X chromosome in voles.
Exclusive dimuon production in ultraperipheral collisions (UPC), resulting from photon-photon interactions in the strong electromagnetic fields of colliding high-energy lead nuclei, $\mathrm{PbPb}(\gamma\gamma) \rightarrow \mu^+\mu^- (\mathrm{Pb}^{(\star)}\mathrm{Pb}^{(\star)} )$, is studied using $\mathcal{L}_{\mathrm{int}} = 0.48$ nb$^{-1}$ of $\sqrt{s_\mathrm{NN}}=5.02$ TeV lead-lead collision data at the LHC with the ATLAS detector. Dimuon pairs are measured in the fiducial region $p_{\mathrm{T}\mu} > 4$ GeV, $|\eta_{\mu}| 10$ GeV, and $p_{\mathrm{T,\mu\mu}} < 2$ GeV. The primary background from single-dissociative processes is extracted from the data using a template fitting technique. Differential cross sections are presented as a function of $m_{\mu\mu}$, absolute pair rapidity ($|y_{\mu\mu}|$), scattering angle in the dimuon rest frame ($|\cos \vartheta^{\star}_{\mu\mu}|$) and the colliding photon energies. The total cross section of the UPC $\gamma \gamma \rightarrow \mu^{+}\mu^{-}$ process in the fiducial volume is measured to be $\sigma_{\mathrm{fid}}^{\mu\mu} = 34.1 \! \pm \! 0.3 \mathrm{(stat.)} \! \pm \! 0.7 \mathrm{(syst.)}$ $\mu\mathrm{b}$. Generally good agreement is found with calculations from STARlight, which incorporate the leading-order Breit-Wheeler process with no final-state effects, albeit differences between the measurements and theoretical expectations are observed. In particular, the measured cross sections at larger $|y_{\mu\mu}|$ are found to be about 10-20% larger in data than in the calculations, suggesting the presence of larger fluxes of photons in the initial state. Modification of the dimuon cross sections in the presence of forward and/or backward neutron production is also studied and is found to be associated with a harder incoming photon spectrum, consistent with expectations.
At present new SuperKEKB collider is under commissioning at KEK (Japan) while the Belle II detector for experiments at this collider is at the final stage of the construction. The luminosity of this collider will exceed the previous one by about 40 times, amounting to 8 × 1035cm−2s−1. The electromagnetic calorimeter is a very important component of the BELLE II detector. This calorimeter is described in this report.
This paper reports on the investigation of coherent structures in a high-swirl jet with vortex breakdown (Re = 5 000) and combustion of a methane/air mixture (with equivalence ratio equal to 0.7 and 1.4). The measurements were performed by combined application of the stereo PIV, OH PLIF and HCHO PLIF techniques. The velocity data were processed by the proper orthogonal decomposition (POD) and the PLIF data was conditionally sampled according to the POD correlation coefficients. For the non-reacting jet and lean flame, the POD has revealed presence of a coherent structure, consisted of helical vortex structures in the inner and outer mixing layers. Based on the PLIF data it was found that the inner spiraling vortex structure was correlated with positive fluctuations of the local heat release.
New acceleration technology is mandatory for the future elucidation of fundamental particles and their interactions. A promising approach is to exploit the properties of plasmas. Past research has focused on creating large-amplitude plasma waves by injecting an intense laser pulse or an electron bunch into the plasma. However, the maximum energy gain of electrons accelerated in a single plasma stage is limited by the energy of the driver. Proton bunches are the most promising drivers of wakefields to accelerate electrons to the TeV energy scale in a single stage. An experimental program at CERN—the AWAKE experiment—has been launched to study in detail the important physical processes and to demonstrate the power of proton-driven plasma wakefield acceleration. Here we review the physical principles and some experimental considerations for a future proton-driven plasma wakefield accelerator.
The exact solution of the Schrödinger equation for the one-dimensional system of interacting particles with linear dispersion law in an arbitrary external field is found. The solution is reduced to two groups of particles moving with constant velocities in the opposite directions with a fixed distance between the particles in each group. The problem is applied to the edge states of the 2D topological insulator.
