A statistical combination of searches is presented for massive resonances decaying to WW, WZ, ZZ, WH, and ZH boson pairs in proton-proton collision data collected by the CMS experiment at the LHC. The data are taken at centre-of-mass energies of 8 and 13 TeV, corresponding to respective integrated luminosities of 19.7 and up to 2.7 inverse femtobarns. The results are interpreted in the context of heavy vector triplet and singlet models that mimic properties of composite-Higgs models predicting W' and Z' bosons decaying to WZ, WW, WH, and ZH bosons. A model with a bulk graviton that decays into WW and ZZ is also considered. This is the first combined search for WW, WZ, WH, and ZH resonances and yields lower limits on masses at 95% confidence level for W' and Z' singlets at 2.3 TeV, and for a triplet at 2.4 TeV. The limits on the production cross section of a narrow bulk graviton resonance with the curvature scale of the warped extra dimension k = 0.5, in the mass range of 0.6 to 4.0 TeV, are the most stringent published to date.
Decays $D\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{e}^{+}{\ensuremath{\nu}}_{e}$ and ${D}_{s}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{e}^{+}{\ensuremath{\nu}}_{e}$ serve as probes that check the existence of constituent $q\overline{q}$ components in the wave functions of scalar mesons decaying into ${\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$. There exists a great deal of concrete evidence in favor of the exotic four-quark nature of light scalars.

We analyze the BESIII and CLEO data on the decays ${D}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{e}^{+}{\ensuremath{\nu}}_{e}$ and ${D}_{s}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{e}^{+}{\ensuremath{\nu}}_{e}$.

The results of these experiments together can be interpreted in favor of the four-quark nature of light scalar mesons $\ensuremath{\sigma}(500)$ and ${f}_{0}(980)$. Our approach can also be applied to the description of other similar decays involving light scalars.
LiGaSe2 (LGSe) and LiInSe2 (LISe) are wide band-gap nonlinear crystals transparent in the mid-IR spectral range. LiGa0.5In0.5Se2 (LGISe) is a new mixed crystal, a solid solution in the system LGSe–LISe, which exhibits the same orthorhombic structure (mm2) as the parent compounds in the same time being more technological with regard to the growth process. In comparison with LGSe and LISe its homogeneity range is broader in the phase diagram. About 10% of the Li ions in LGISe occupy octahedral positions (octapores) with coordination number of 3.

The band-gap of LGISe is estimated to be 2.94 eV at room temperature and 3.04 eV at 80 K. The transparency at the 0-level extends from 0.47 to 13 µm. LGISe crystals exhibit luminescence in broad bands centered near 1.7 and 1.25 eV which is excited most effectively by band-to-band transition. From the measured principal refractive indices and the fitted Sellmeier equations second-harmonic generation from 1.75 to 11.8 μm (fundamental wavelength) is predicted.

The nonlinear coefficients of LGISe have values between those of LGSe and LISe. 6LGISe crystals are considered promising also for detection of thermal neutrons.
Estimation of the structure response to seismic motion is an important part of structural analysis related to mitigation of seismic risk caused by earthquakes. Many methods of computing structure response require knowledge of mechanical properties of the ground which could be derived from near-surface seismic studies. In this paper we address computationally efficient implementation of the wave-equation tomography. This method allows inverting first-arrival seismic waveforms for updating seismic velocity model which can be further used for estimating mechanical properties. We present computationally efficient hybrid kinematic-dynamic method for finite-difference (FD) modeling of the first-arrival seismic waveforms. At every time step the FD computations are performed only in a moving narrowband following the first-arrival wavefront. In terms of computations we get two advantages from this approach: computation speedup and memory savings when storing computed first-arrival waveforms (it is not necessary to make calculations or store the complete numerical grid). Proposed approach appears to be specifically useful for constructing the so-called sensitivity kernels widely used for tomographic velocity update from seismic data. We then apply the proposed approach for efficient implementation of the wave-equation tomography of the first-arrival seismic waveforms.
Initial stage of downward flow of gas-sheared liquid film in a vertical rectangular duct was studied using brightness-based laser-induced fluorescence technique. Measurements were resolved along both longitudinal and transverse coordinates and time. The initial high-frequency waves which are formed at the inlet were found to be two-dimensional. These waves are promptly broken into localised horseshoe-shaped waves which merge downstream to form large-scale quasi-2D disturbance waves. Peculiarities of three-dimensional evolution of waves of different types were studied in a wide range of flow parameters.

The butterfly (Papilionoidea) fauna of Cambodia is very rich but too insufficiently studied. Results are presented of occasional photographic records of butterflies (Lepidoptera, Papilionoidea) made in 2016–2019 (some also in 2006) along with studies on the Odonata fauna in 67 localities of western and northern provinces of Cambodia: Pursat, Siem Reap, Preah Vihear and Stung Treng. This paper completes the two previous communications of this series devoted to the south-western and eastern provinces of this country. In total, 162 identified and 13 provisionally identified species are listed; 22 species ( Miletus ancon , Arhopala agrata , A. alesia , A. allata , A. ammonides , A. atrax , A. aurelia , A. moolaiana , A. silhetensis , Drupadia theda , Anthene licates , Prosotas aluta , Danaus chrysippus , Cirrochroa surya , Doleschallia bisaltide , Athyma ranga , Euthalia recta , Burara oedipodea , Hasora chromus , Pseudocoladenia dan , Koruthalaios sindu , Parnara ganga ) are for the first time reported in literature for Cambodia. These and some problematic species are illustrated. Some misidentifications in the two first communications of the series are made; due to reidentification Arhopala camdana and Borbo cinnara are for the first time reported for Cambodia in literature.
The method of experiments with internal targets in the storage ring was proposed at the moment of creation of the first storage ring of charged particles. This method has demonstrated dramatic advances during the last 50 years. The most clearly visible progress can be seen in experiments with polarized gas targets.

In this report we shall review: (a) the experiments on nuclear physics in the storage rings on the measure of polarization observables in different reactions with electron/positron and proton/deuteron beams, (b) the use of polarized gas targets in the storage ring for polarimetry of the circulated beams.

The present status of the activity in this field of experimental physics is given.
The etiologic factor of idiopathic scoliosis (IS) is a subject of discussions for scientists of different disciplines. The great number of theories testifies to an absence of a uniform sight on etiology and pathogenesis of this pathology. Objectives: to investigate the mechanism of genetic determination of IS. Materials and methods: 101 probands with II–IV grade IS and 703 family members of I–III degree of relationship were examined by clinical-genetic, radiological and optical-topographical methods. The pedigrees were processed by a method of segregation analysis. G3 exon of agrecan gene was studied from isolated family DNA by method of PCR reaction. Results: Segregation analysis of pedigrees, in which proband had II–IV grade IS has shown, that IS is inherited according to autosomal-dominant type with incomplete genotype penetrance depending on sex and age. It is revealed that idiopathic scoliosis is controlled by a major gene. Study of connection of agrecan gene to determination of IS development on a small sample of pedigrees has not revealed a reliable association of IC with polymorphism of G3 exon. Investigation of another exons of agrecan gene on expanded pedigrees is continued.
Zic3 regulates early embryonic patterning in vertebrates. Loss of Zic3 function is known to disrupt gastrulation, left-right patterning, and neurogenesis. However, molecular events downstream of this transcription factor are poorly characterized. Here we use the zebrafish as a model to study the developmental role of Zic3 in vivo, by applying a combination of two powerful genomics approaches – ChIP-seq and microarray. Besides confirming direct regulation of previously implicated Zic3 targets of the Nodal and canonical Wnt pathways, analysis of gastrula stage embryos uncovered a number of novel candidate target genes, among which were members of the non-canonical Wnt pathway and the neural pre-pattern genes. A similar analysis in zic3-expressing cells obtained by FACS at segmentation stage revealed a dramatic shift in Zic3 binding site locations and identified an entirely distinct set of target genes associated with later developmental functions such as neural development. We demonstrate cis-regulation of several of these target genes by Zic3 using in vivo enhancer assay. Analysis of Zic3 binding sites revealed a distribution biased towards distal intergenic regions, indicative of a long distance regulatory mechanism; some of these binding sites are highly conserved during evolution and act as functional enhancers. This demonstrated that Zic3 regulation of developmental genes is achieved predominantly through long distance regulatory mechanism and revealed that developmental transitions could be accompanied by dramatic changes in regulatory landscape.
The neutral partner of the Z ± b (10610), the Z 0 b (10610) decaying to ϒ(2, 3S)π 0 , is observed for the first time with a 6.5σ significance using a Dalitz analysis of ϒ(5S) → ϒ(2, 3S)π 0 π 0 decays.

The results are obtained with a 121.4 fb -1 data sample collected with the Belle detector at the ϒ(5S) resonance at the KEKB asymmetric-energy e + e -collider.

We report the first observation of ϒ(5S) → ϒ(1, 2, 3S)π 0 π 0 decays. First results on the analysis of the three-body± are also reported.
The article dedicates to the study of microelements in the blood serum of women of reproductive age, with newly diagnosed hypothyroidism (subclinical and manifest), living in disadvantaged areas of the Aral Sea region. This article presents the study of 1154 women. Every fourth woman (25%) has an essential deficiency of such microelements like iodine, selenium, iron, zinc independently of thyroid function. Our study discovered negative associations of TSH concentration with essential microelements like manganese, copper, selenium, and positiveassociation with iodine. We also obtain positive relationships between AT-TPO and zinc and iodine. The relationship of zinc with AT – TPO level and thyroid status, especially in the regions with sufficient ioduria among residents,require further researchto study it’spossible effecton thyroid dysfunctions. We established positive associations of free T4 with essential microelements like manganese, iron, and negative association with iodine. Estimation of thyroid status and toxic microelementsrevealed positive association of free T4 with cadmium, nickel, and lead, and negativewith mercury.

I discuss the accuracy and computational time of the discrete dipole approximation (DDA) when applied to metal nanoparticles. The accuracy of the DDA can be made satisfactory by refining discretization (or increasing number of dipoles), but the required discretization level strongly depends on particle shape and refractive index (or wavelength) as well as on a particular computed quantity of interest. I present certain guidelines for setting the appropriate discretization, but they can not be considered comprehensive. On contrary, the required computational time can be accurately estimated once the number of dipoles is set. For that approximate expression for the required number of iterations of the iterative solver is used, which validity was tested for a wide range of refractive index.
The N ‐(2,3‐butadienyl)carboxamide of isopimaric acid, that is, compound 3 , was prepared through a two‐step synthetic procedure starting from the natural diterpene isopimaric acid. The Pd‐catalyzed cross‐coupling and subsequent cyclization of terpenoid allene 3 with several aryl iodides and aryl bromides gave access to optically active diterpenoid–oxazoline derivatives in good to excellent yields. The functional group tolerance in the aryl iodides was demonstrated by several examples, including substrates with additional N ‐ tert ‐butoxycarbonyl‐protected amino, hydroxy, and carboxy substituents in the ortho position. The cross‐coupling–cyclization reaction of those compounds with allene 3 proceeded selectively with the formation of cyclization products on the substituent in the aromatic ring. This transformation opens a potential route to the synthesis of hybrid compounds containing a tricyclic diterpenoid and several heterocycles.
Induced pluripotent stem cells (iPSCs) are a new type of pluripotent cells that can be obtained by reprogramming animal and human differentiated cells.

In this review, issues related to the nature of iPSCs are discussed and different methods of iPSC production are described. We particularly focused on methods of iPSC production without the genetic modification of the cell genome and with means for increasing the iPSC production efficiency.

The possibility and issues related to the safety of iPSC use in cell replacement therapy of human diseases and a study of new medicines are considered.
The influence of the Reynolds number on the statistics of a near-wall reverse flow phenomenon, taking place in a turbulent duct flow, is studied. An increase in the NWRF probability is found in both the core and corner regions of the duct walls for higher Reynolds number. The mechanism of the NWRF formation, described recently by Zaripov et al. [1, 2], is validated for higher Reynolds number flows.
Intensively evaporating liquid films moving under the action of the cocurrent gas flow in a microchannel are promising for the use in modern cooling systems of semiconductor devices with high local heat release.

This work has studied the dependence of the critical heat flux on the inclination angle of the channel.

It has been found that the inclination angle in the plane parallel to the flow has no significant effect on the critical heat flux. Whereas the inclination angle in the plane perpendicular to the flow, on the contrary, significantly changes the value of the critical heat flux. However, for a given flow rate of fluid there is a threshold gas velocity at which the critical heat flux does not differ from the case of zero inclination of the channel. Thus, it can be concluded that the cooling system based on shear-driven liquid films can be potentially used when direction of the gravity changes.
Owing to their inherent pore structure, porous metal–organic frameworks (MOFs) can undergo postsynthetic modification, such as loading extra-framework proton carriers. However, strategies for improving the proton conductivity for nonporous MOFs are largely lacking, although increasing numbers of nonporous MOFs exhibit promising proton conductivities. Often, high humidity is required for nonporous MOFs to achieve high conductivities, but to date no clear mechanisms have been experimentally identified.

Here we describe the new materials MFM-550(M), [M(HL1)], (H4L1 = biphenyl-4,4′-diphosphonic acid; M = La, Ce, Nd, Sm, Gd, Ho), MFM-550(Ba), [Ba(H2L1)], and MFM-555(M), [M(HL2)], (H4L2 = benzene-1,4-diphosphonic acid; M = La, Ce, Nd, Sm, Gd, Ho), and report enhanced proton conductivities in these nonporous materials by (i) replacing the metal ion to one with a lower oxidation state, (ii) reducing the length of the organic ligand, and (iii) introducing additional acidic protons on the MOF surface. Additionally, we report a comprehensive investigation using in situ 2H NMR and neutron spectroscopy, coupled with molecular dynamic modeling, to elucidate the role of humidity in assembling interconnected networks for proton hopping.

Increased framework proton density in these materials can lead to an enhancement in proton conductivity of up to 4 orders of magnitude. This study constructs a relationship between framework proton density and the corresponding proton conductivity in nonporous MOFs, and directly explains the role of both surface protons and external water in assembling the proton conduction pathways.
The present work investigates the application of the plasma of glow discharge to deposit the fluoropolymer coatings.

Two series of experiments were carried out in which the influence of pressure and current strength on surface coatings morphology during its surface treatment with glow discharge plasma was investigated. The surface morphology is investigated by a scanning electron microscope (SEM), and the water contact angle (WCA) is measured.

The fact that the choice of pressure significantly affects the morphology and properties of the deposited coating is established.
In various fields of microscopy, a fairly common task is to count and determine the size of the studied objects. Sometimes this is a one-time tedious task that is done by lab personnel without the programming skills.

In this paper, we present an approach that allows researchers to perform automated processing of research imaging data using our services and even to train deep neural networks on their own in no code mode.
It is believed that damage to the membranes of brain cells of schizophrenia (SCZ) patients induces the formation of autoantigens and autoantibodies. Nevertheless, the importance of immunological changes leading to the loss of tolerance to self-antigens in the genesis of SCZ has not been established. The MALDI mass spectra of the IgG light chains of 20 healthy donors were relatively homogeneous and characterized by one peak with only one maximum. In contrast to the healthy donors, the MALDI mass spectra of IgG light chains corresponding to 20 SCZ patients demonstrated, similarly to 20 autoimmune systemic lupus erythematosus (SLE) patients, two maxima of a comparable intensity. In addition, the MALDI spectra of the IgG light chains of five SLE and four SCZ patients contained a small additional brightly pronounced peak with remarkably lower molecular mass compared with the main one. DNase autoantibodies (abzymes) can be found in the blood of patients with several autoimmune diseases, while the blood of healthy donors or patients with diseases without a significant disturbance of the immune status does not contain DNase abzymes. Here, we present the first analysis of anti-DNA antibodies and DNase abzymes in the sera of SCZ patients. Several strict criteria have been applied to show that the DNase activity is an intrinsic property of IgGs from the sera of SCZ patients. The sera of approximately 30% of SCZ patients displayed a higher content of antibodies (compared with 37% of SLE) interacting with single- and double-stranded DNA compared with healthy donors. Antibodies with DNase activity were revealed in 80% of the patients. These data indicate that some SCZ patients may show signs of typical autoimmune processes to a certain extent.
While Dehn functions D(n) of finitely presented groups have been well studied in the literature, mean Dehn functions have received less attention. Gromov introduced the notion of the mean Dehn function Dmean(n) of a group, suggesting that in many cases it should grow more slowly than the Dehn function itself This paper presents computations pointing in this direction. In the case of any finite presentation of an infinite finitely generated abelian group (for which it is well known that D(n) ~ n2 except in the 1-dimensional case), we show that the three variants Dosmean(n), Dsmean(n) and Dmean(n) all are bounded above by Kn(In n)2, where the constant K depends only on the presentation (and the geodesic combing) chosen. This improves an earlier bound given by Kukina and Roman'kov.
In the current study, we aimed to investigate the associations between the natural variability in hyperactivity and inattention scores, as well as their combination with EEG oscillatory responses in the Stop-Signal task in a sample of healthy children. During performance, the Stop-Signal task EEGs were recorded in 94 Caucasian children (40 girls) from 7 to 10 years. Hyperactivity/inattention and inattention scores positively correlated with RT variability. Hyperactivity/inattention and inattention scores negatively correlated with an increase in beta spectral power in the first 200 ms after presentation of the Go stimulus. Such results are in line with the lack of arousal model in ADHD children and can be associated with less sensory arousal in the early stages of perception in children with symptoms of inattention. The subsequent greater increase in theta rhythm at about 300 ms after presentation of the Go stimulus in children with higher inattention scores may be associated with increased attention processes and compensation for insufficient vigilance in the early stages of perception.

The aim of this paper is to select an optimal numerical method for determining the parameters of chemical reactions. The importance of the topic is due to the modern needs of industry, such as the improvement of chemical reactors and oil or gas processing.

The paper deals with the problem of determining reaction rate constants using gradient methods and stochastic optimization algorithms. To solve an forward problem, implicit methods for solving stiff ODE systems are used. A correlation method of practical identifiability of the required parameters is used. The genetic algorithm, particle swarm method, and fast annealing method are implemented to solve an inverse problem. The gradient method for the solution of the inverse problem is implemented, and a formula for gradient of the functional is given with the corresponding adjoint problem. We apply an identifiability analysis of the unknown coefficients and arrange the coefficients in the order of their identifiability.

We show that the best approach is to apply global optimization methods to find the interval of global solution and after that we refine inverse problem solution using gradient approach.
