Measurements of ${B}_{c}^{+}$ production and mass are performed with the decay mode ${B}_{c}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{\ensuremath{\pi}}^{+}$ using $0.37\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of data collected in $pp$ collisions at $\sqrt{s}=7\text{ }\text{ }\mathrm{TeV}$ by the LHCb experiment.

The ratio of the production cross section times branching fraction between the ${B}_{c}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{\ensuremath{\pi}}^{+}$ and the ${B}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{+}$ decays is measured to be $\mathbf{(}0.68\ifmmode\pm\else\textpm\fi{}0.10(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.03(\mathrm{syst})\ifmmode\pm\else\textpm\fi{}0.05(\mathrm{\text{lifetime}})\mathbf{)}%$ for ${B}_{c}^{+}$ and ${B}^{+}$ mesons with transverse momenta ${p}_{\mathrm{T}}>4\text{ }\text{ }\mathrm{GeV}/c$ and pseudorapidities $2.5<\ensuremath{\eta}<4.5$.

Arterial hypertension is one of the most common chronic diseases in adults all over the world. This pathology can not only reduce patients’ life quality, but can also be accompanied by a number of complications. Despite the fact that there is a large group of antihypertensive drugs on the market, mainly representing different combinations of inhibitors of the renin-angiotensin system, adrenoreceptor blockers in combination with diuretics, there is no generally accepted “gold standard” for drugs that would not have side effects. The review discusses the main aspects of antisense oligonucleotides use in the context of arterial hypertension. It is well known that the medical implementation of antisense oligonucleotides aims to block the expression of particular genes involved in the pathology development, and a key advantage of this technique is a high selectivity of the effect. However, with the undoubted advantages of the method, there are difficulties in its application, related both to the properties of the oligonucleotides themselves (insufficient stability and poor penetration into cells), and to the variety of mechanisms of the origin of a particular pathology, arterial hypertension, in our case. The review provides a brief description of the main molecular targets for antisense treatment of hypertensive disease. The newest targets for therapy with oligonucleotides – microRNAs – are discussed. The main modifications of antisense nucleotides, designed to increase the duration of their effects and simplify the delivery of this type of drugs to the targets are discussed, in particular, combining antisense oligonucleotides with adenovirus-based expression vectors. Particular attention is given to antisense oligonucleotides in the complex with nanoparticles. The review discusses the results of the use of titanium dioxide (TiO2) containing antisense nanocomposites for the angiotensin converting enzyme in rats with stress induced arterial hypertension (ISIAH). It was shown that the use of antisense oligonucleotides continues to be a promising technique for studying the mechanisms of various forms of hypertensive disease and has a high potential for therapeutic use.
Spun-knots (respectively, spinning tori) in [Formula: see text] made from classical 1-knots compose an important class of 2-knots (respectively, embedded tori) contained in [Formula: see text]. Virtual 1-knots are generalizations of classical 1-knots.

We generalize these constructions to the virtual 1-knot case by using what we call, in this paper, the spinning construction of submanifolds. The construction proceeds as follows: For a virtual 1-knot [Formula: see text], take an embedded circle [Formula: see text] contained in (a closed oriented surface [Formula: see text])×(a closed interval [Formula: see text]), where [Formula: see text] is called a representing surface in virtual 1-knot theory. Embed [Formula: see text] in [Formula: see text] by an embedding map [Formula: see text], and let [Formula: see text] stand for [Formula: see text] Regard the tubular neighborhood of [Formula: see text] in [Formula: see text] as the result of rotating [Formula: see text] around [Formula: see text]. Rotate [Formula: see text] together then with [Formula: see text]. When [Formula: see text], we obtain an embedded torus [Formula: see text]. We generalize the construction in the virtual 1-knot case written in the first paragraph, and we also succeed to make a consistent construction of one-dimensional-higher submanifolds from any virtual two-dimensional knot.

We prove the following: The embedding type [Formula: see text] in [Formula: see text] depends only on [Formula: see text], and does not depend on [Formula: see text]. Furthermore, the submanifolds, [Formula: see text] and 'the embedded torus made from [Formula: see text] by using Satoh's method', of [Formula: see text] are isotopic. Fiberwise equivalence of diagrams refers to fiberwise equivalence of tori in 4-space that lie over the diagrams. We prove that two virtual 1-knot diagrams [Formula: see text] and [Formula: see text] are fiberwise equivalent if and only if [Formula: see text] and [Formula: see text] are rotational welded equivalent (see the body of the paper for this definition). Note that Satoh's method says nothing about the virtual 2-knot case. Rourke's interpretation of Satoh's method is that one puts 'fiber-circles' on each point of each virtual 1-knot diagram. If there is no virtual branch point in a virtual 2-knot diagram, our way gives such fiber-circles to each point of the virtual 2-knot diagram. Furthermore we prove the following: If a virtual 2-knot diagram [Formula: see text] has a virtual branch point, [Formula: see text] cannot be covered by such fiber-circles. Hence Rourke's method cannot be generalized to the virtual 2-knot case. Only the spinning construction introduced in this paper works for now.
Main technical features of Low Energy Charged Particle Sensor (LECPS) are described, taking into account LECPS high sensitivity, wide dynamic range, and conditions of in-flight operation on-board a satellite. LECPS input cascade is capable of current measurement as low as 1 pA within a 120 dB dynamic range, providing error level below 20%. Statistical calculations of acquired data, measuring time considerations and implementation of input cascade auto-calibration technique were applied to gain the best possible stability and accuracy over −20° to +50°C operation temperature.
The Regge inspired k T -factorization scheme expresses the scattering amplitude for exclusive leptoproduction of a light vector meson ρ in terms of two impact factors, one for the γ *ρ transition and the other one for the nucleon to nucleon transition, with, at leading order, a two "reggeized" gluon exchange in the t-channel.

We report here on a recent phenomenological study [?] where we apply a previously developped scheme [?] which consistently takes into account the twist 3 distribution amplitudes for transversely polarized ρ meson.The computation of the γ * → ρ impact factor are performed within collinear factorization of QCD, up to the twist 3 level, based on the Collinear Factorization scheme applied to the amplitudes γ * (λ γ )g(k) → g(rk)ρ(λ ρ ).

Our results are in good agreement with high energy experimental data for the ratios of helicity amplitudes.
We have studied the two-phase flow in a microchannel with cross-section of 0.05×20 mm2. The following two-phase flow regimes have been registered: jet, bubble, stratified, annular, and churn ones.

The main features of flow regimes in this channel such as formation of liquid droplets in all two-phase flows have been distinguished.
N-doping of carbon support prevents sintering of Cu and provides its high catalytic activity in H2 formation from formic acid.
Impact of different parameters on the decomposition rates of hydrate at negative temperatures with depressurisation method has been studied. In previous work it was demonstrated that decomposition rates of hydrates suspensions in oil at static conditions can be limited by the self-preservation phenomenon. Our experimental research shows that appearance of self-preservation depends on many parameters such as components composition of oil, presence of shear in the system while decomposing hydrates and probably on the history of the sample.
Настоящая работа продолжает исследования принципов больших уклонений обобщенных процессов восстановления, начатые в [1], [2].

Основным объектом изучения являются вероятности больших уклонений траекторий обобщенных процессов восстановления. Работа состоит из двух частей. В части I при некотором условии на распределение процесса получен так называемый первый частичный локальный принцип больших уклонений для траекторий обобщенного процесса восстановления. В части II при альтернативном условии получен второй частичный локальный принцип больших уклонений.

При дополнительных условиях получены также "полный локальный" и "полный интегральный" принципы больших уклонений для обобщенных процессов восстановления.
The MBD4 enzyme initiates the process of DNA demethylation by the excision of modified DNA bases, resulting in the formation of apurinic/apyrimidinic sites. MBD4 contains a methyl-CpG-binding domain which provides the localization of the enzyme at the CpG sites, and a DNA glycosylase domain that is responsible for the catalytic activity. The aim of this work was to clarify the mechanisms of specific site recognition and formation of catalytically active complexes between model DNA substrates and the catalytic N-glycosylase domain MBD4cat. The conformational changes in MBD4cat and DNA substrates during their interaction were recorded in real time by stopped-flow detection of the fluorescence of tryptophan residues in the enzyme and fluorophores in DNA. A kinetic scheme of MBD4cat interaction with DNA was proposed, and the rate constants for the formation and decomposition of transient reaction intermediates were calculated. Using DNA substrates of different lengths, the formation of the catalytically active complex was shown to follow the primary DNA binding step which is responsible for the search and recognition of the modified base. The results reveal that in the primary complex of MBD4cat with DNA containing modified nucleotides, local melting and bending of the DNA strand occur. On the next step, when the catalytically competent conformation of the enzyme-substrate complex is formed, the modified nucleotide is everted from the double DNA helix into the active center and the void in the helix is filled by the enzyme's amino acids.
The wild type red fox is common to Europe, Asia, North Africa, and North America. Furthermore, it has accommodated itself so well in Australia, where it was taken from England, that it has spread over the entire continent. It adapts easily to different climates and biocoenoses—in the open; in the forest, highland or lowland; on the coast; or inland.

In 1827, C. A. Bjorkman was the first to try to make the cross fox reproduce in captivity, but his attempt failed. Modern fur animal farming is believed to have been started in 1895 on Prince Edward Island, St. Lawrence Bay, Canada, by Charles Dalton, Robert Oulton, and Robert Rayner. Their animals were the origin of the farm-bred standard silver fox. Another stock of silver fox was associated with animals bred by J. Beetz, a pair of which was shipped to Norway in 1914.

Over the past 100 yr, fur animal breeding has developed into an industry of great economic importance, especially in Nordic countries.
These measurements are obtained from a sample of (772±11)×10⁶ BB̄ pairs collected at the Υ(4S) resonance by the Belle detector at the KEKB asymmetric energy electron–positron collider.

We report the first observation of the Ξc(2930)⁰ charmed-strange baryon with a significance greater than 5σ. The Ξc(2930)⁰ is found in its decay to K⁻Λc⁺ in B⁻ → K⁻Λc⁺Λ̄c⁻ decays. The measured mass and width are [2928.9 ± 3.0(stat.)⁺⁰.⁹₋₁₂.₀(syst.)] MeV/c² and [19.5 ± 8.4(stat.) ⁺⁵.⁹₋₇.₉(syst.)] MeV, respectively, and the product branching fraction is B(B⁻ → Ξc(2930)⁰Λ̄c⁻)B(Ξc(2930)⁰ → K⁻Λc⁺)=[1.73 ± 0.45(stat.) ± 0.21(syst.)]×10⁻⁴. We also measure B(B⁻ → K⁻Λc⁺Λ̄c⁻) = [4.80 ± 0.43(stat.) ± 0.60(syst.)] × 10⁻⁴ with improved precision, and search for the charmonium-like state Y(4660) and its spin partner, Yη, in the Λc⁺Λ̄c⁻ invariant mass spectrum.

No clear signals of the Y(4660) nor its spin partner are observed and the 90% credibility level (C.L.) upper limits on their production rates are determined.
The review assesses the recently published book by V. T. Golovachev, dedicated to the ethnographic expedition of Russian naval officer and researcher Paul (Pavel Ivanovich) Ibis to Taiwan in early 1875. This expedition laid the foundation for scientific study of the material and spiritual culture of the island natives, from the Paleolithic era to ethnographical time. A thorough study of the book was conducted, as it contains all currently available archival and published materials. As a result of the work of V. T. Golovachev, Russia's priority in the study of Taiwan's ethnology can be considered conclusively proven.
We discuss two families of closed orientable three-dimensional manifolds which arise as cyclic generalizations of two hyperbolic icosahedral manifolds listed by Everitt. Everitt's manifolds are cyclic coverings of the lens space $L_{3,1}$ branched over some 2-component links. We present results on covering properties, fundamental groups, and hyperbolic volumes of the manifolds belonging to these families.
Long-Lived spin States (LLSs) hold a great promise for sustaining non-thermal spin order and investigating various slow processes by Nuclear Magnetic Resonance (NMR) spectroscopy. Of special interest for such application are molecules containing nearly equivalent magnetic nuclei, which possess LLSs even at high magnetic fields.

In this work, we report an LLS in trans- 15 N, 15 N′-azobenzene. The singlet state of the 15 N spin pair exhibits a long-lived character. We solve the challenging problem of generating and detecting this LLS and further increase the LLS population by converting the much higher magnetization of protons into the 15 N singlet spin order. As far as the longevity of this spin order is concerned, various schemes have been tested for sustaining the LLS.

Lifetimes of 17 minutes have been achieved at 16.4 T, a value about 250 times longer than the longitudinal relaxation time of 15 N in this magnetic field. We believe that such extended relaxation times, along with the photochromic properties of azobenzene, which changes conformation upon light irradiation and can be hyperpolarized by using parahydrogen, are promising for designing new experiments with photo-switchable long-lived hyperpolarization.
To assess the long-term outcomes of coronary artery bypass grafting (CABG) and their association with calcification biomarkers.

The study included 129 men (mean age, 61,5±7,5 years) with coronary atherosclerosis who were admitted for CABG surgery. Patients were divided into 2 groups: with favorable and unfavorable (death, myocardial infarction, stroke, surgery) 5-year prognosis after surgery. Before the surgery, the blood concentrations of calcification biomarkers (osteoprotegerin, osteopontin, osteonectin and osteocalcin) were determined in all patients. Results. Long-term outcomes of myocardial revascularization were studied in 92 patients (71%). An unfavorable long-term 5-year period was identified in 28 men (30,4%). In men with an unfavorable 5-year prognosis, the blood osteocalcin level before CABG was 1,2 times higher than in men with a favorable one. Multivariate linear regression showed that the risk of a 5-year unfavorable prognosis for coronary atherosclerosis after myocardial revascularization was associated with the blood osteocalcin concentration, determined before CABG (B=0,018, R 2 =0,285, p=0,008).

The data obtained indicate the relevance of continuing studies on osteocalcin, including with respect to its contribution to coronary atherosclerosis and calcification.
We give a beautiful explicit example of a convex plane curve such that the outer billiard has a given finite number of invariant curves. Moreover, the dynamics on these curves is a standard shift. This example can be considered as an outer analog of the so-called Gutkin billiard tables. We test total integrability of these billiards, in the region between the two invariant curves. Next, we provide computer simulations on the dynamics in this region. At first glance, the dynamics looks regular but by magnifying the picture we see components of chaotic behavior near the hyperbolic periodic orbits. We believe this is a useful geometric example for coexistence of regular and chaotic behavior of twist maps.
We consider an equation by Navier-Stokes type

investigate some questions of identification of solutions and coefficients on the base of analytical representation of solution, in particular by representation of solution in ray series form
Formic acid is a promising liquid organic hydrogen carrier (LOHC) since it has relatively high hydrogen content (4.4 wt%), low inflammability, low toxicity and can be obtained from biomass or from CO2. The aim of the present research was the creation of efficient 1 wt% Pd catalysts supported on mesoporous graphitic carbon (Sibunit) for the hydrogen production from gas-phase formic acid. For this purpose, the carbon support was modified by pyrolysis of deposited precursors containing pyridinic nitrogen such as melamine (Mel), 2,2′-bipyridine (Bpy) or 1,10-phenanthroline (Phen) at 673 K. The following activity trend of the catalysts Pd/Mel/C > Pd/C ~ Pd/Bpy/C > Pd/Phen/C was obtained. The activity of the Pd/Mel/C catalyst was by a factor of 4 higher than the activity of the Pd/C catalyst at about 373 K and the apparent activation energy was significantly lower than those for the other catalysts (32 vs. 42–46 kJ/mol). The high activity of the melamine-based samples was explained by a high dispersion of Pd nanoparticles (~2 nm, HRTEM) and their strong electron-deficient character (XPS) provided by interaction of Pd with pyridinic nitrogen species of the support. The presented results can be used for the development of supported Pd catalysts for hydrogen production from different liquid organic hydrogen carriers.
A long, narrow, relativistic charged particle bunch propagating in plasma is subject to the self-modulation (SM) instability.

We show that SM of a proton bunch can be seeded by the wakefields driven by a preceding electron bunch. With this seeding method, we independently control the amplitude of the seed wakefields with the charge of the electron bunch and the growth rate of SM with the charge of the proton bunch.

SM timing reproducibility and control are at the level of a small fraction of the modulation period. Seeding leads to larger growth of the wakefields than in the instability case.
In many late-replicating euchromatic regions of salivary gland polytene chromosomes, DNA is underrepresented. A mutation in the SuUR gene suppresses underreplication and leads to normal levels of DNA polytenization in these regions.

We identified the SuUR gene and determined its structure. In the SuUR mutant stock a 6-kb insertion was found in the fourth exon of the gene. A single SuUR transcript is present at all stages of Drosophila development and is most abundant in adult females and embryos. The SuUR gene encodes a protein of 962 amino acids whose putative sequence is similar to the N-terminal part of SNF2/SWI2 proteins.

Staining of salivary gland polytene chromosomes with antibodies directed against the SuUR protein shows that the protein is localized mainly in late-replicating regions and in regions of intercalary and pericentric heterochromatin.
The spectroscopical parameters for the molecules from GEISA database have been used. Hence the selection of the molecules was substantially based on the availability of the parameters in the database.

A calculation of the absorption cross section of some molecules at the wavelengths transmitted by a CO2 laser filled with different isotopes is presented. The pressure and temperature dependence of the cross sections are described by coefficients; these coefficients were calculated for the largest absorption cross sections for each molecule.

The results of the calculations may be used in designing the differential absorption technique for remote monitoring of these molecules. The absorption cross sections of CH3OH and HCOOH at low pressures for all these CO2 lasers are also presented. These calculations are provided for design of new CO2-laser-pumped far-infrared lasers.
Facial pain resembling trigeminal neuralgia is not a common clinical feature of cervical spinal cord tumor. Depending on nature of the facial pain, differential diagnosis tends to include neurovascular conflict, multiple sclerosis, cerebellopontine angle tumors, herpes zoster, facial injuries, and other conditions involving trigeminal nerve, ganglion, and root.

Here, we present a unique case of pain in trigeminal distribution due to an intramedullary tumor in the upper cervical spinal cord.A 27-year-old male was admitted with complaints of intense facial pain on the right side lasting for several years. MRI revealed an intramedullary lesion at the C1 level and no signs of a neurovascular conflict or a demyelination. This lesion was removed microsurgically, with the subtotal resection immediately abolishing the pain and causing no additional neurological deficit. Histological analysis revealed ganglioglioma, Grade 1.

After 5-day hospital stay, the patient was discharged home; 2-year follow-up showed no tumor recurrence on MRI and persistent relief of facial pain.Secondary trigeminal neuralgia may be explained by a pathological process in vicinity of the spinal trigeminal nuclei. Removing the tumor may be expected to provide complete and lasting pain relief.
