This paper reports on a search for electroweak diboson ($WW/WZ/ZZ$) production in association with a high-mass dijet system, using data from proton-proton collisions at a center-of-mass energy of $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$. The data, corresponding to an integrated luminosity of $35.5\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, were recorded with the ATLAS detector in 2015 and 2016 at the Large Hadron Collider. The search is performed in final states in which one boson decays leptonically, and the other boson decays hadronically. The hadronically decaying $W/Z$ boson is reconstructed as either two small-radius jets or one large-radius jet using jet substructure techniques. The electroweak production of $WW/WZ/ZZ$ in association with two jets is measured with an observed (expected) significance of 2.7 (2.5) standard deviations, and the fiducial cross section is measured to be $45.1\ifmmode\pm\else\textpm\fi{}8.6(\mathrm{stat}.{)}_{\ensuremath{-}14.6}^{+15.9}(\mathrm{syst}.)\text{ }\text{ }\mathrm{fb}$.
The slotted nozzles can be an alternative to Laval nozzles. The jets inflowing through the holes can be directed towards each other (opposing jets) or be focused at a single point on the axis (focused jets).

It has been shown numerically and experimentally that it is necessary to consider the effect of viscosity for the numerical modeling of focused jets in order to predict the flow parameters on the channel surface.

Nevertheless, the calculation accuracy based on the unsteady Euler equation is quite sufficient for averaged values in the output cross section.
Let X be a family of graphs and X n the set of n-vertex graphs in X. A graph U (n) containing all graphs from X n as induced subgraphs is called n-universal for X. Moreover, we say that U (n) is a propern-universal graph for X if it belongs to X. In the present paper, we construct a proper n-universal graph for the class of split permutation graphs. Our solution includes two ingredients: a proper universal 321-avoiding permutation and a bijection between 321-avoiding permutations and symmetric split permutation graphs. The n-universal split permutation graph constructed in this paper has 4n 3 vertices, which means that this construction is order-optimal.
The structure of titanium carbide nanoparticles formed at electric arc spraying of composite Ti-C electrodes is studied.

It is shown that the size of titanium carbide particles in condensation products varies in the range of 10–50 nm, crystal lattice of nanoparticles corresponds to TiC carbide. Annealing the material in an oxygen-containing atmosphere leads to carbon burnout and oxidation of titanium carbide nanoparticles. The main part of carbon is oxidized in the temperature range of 250–500°C, oxidation of titanium carbide nanoparticles occurs in the range from 320 to 400°C. When annealed to the temperatures of 1000°C, sintering of oxide TiO 2 nanoparticles occurs.

The proposed method can be used to obtain particles of titanium carbide with a shape close to the TiC crystal.
Herewith, we report for the first time the crystal structure of tetrapeptide FwKT (Phe-D-Trp-Lys-Thr), which is considered to represent an epitope for biomedically relevant hormone somatostatin. The target molecule was successfully crystalized, solved and refined as a conjugate of the tetrapeptide moiety bearing a protective group DOTA at the N-terminus and methylated at the O-terminus. The combination of a hormone active site and a powerful chelator make the substance a highly prospective targeted drug delivery system, especially for peptide receptor radionuclide therapy (PRRT) applications.

BACKGROUND: Type 2 diabetes and osteoporosis are widespread diseases in the middle-aged and elderly people. Most studies of osteoporosis in patients with type 2 diabetes have been performed in women; meantime risk factors for lowering bone mineral density (BMD) in men have been little studied. AIMS: to identify risk factors for decreased BMD at the lumbar spine, femoral neck and forearm in men with type 2 diabetes . METHODS: Eighty two men from 50 to 75 years old, with duration of diabetes for at least one year, were included in the study. Individuals with known risk factors for secondary osteoporosis were not included. Twenty-three men with normal BMD having no diabetes or obesity were acted as control. The T-score at the lumbar spine, femoral neck and forearm of a non-dominant arm, as well as body composition parameters, were evaluated by dual-energy X-ray absorptiometry. The levels of hormones that affect bone metabolism (parathyroid hormone, free testosterone, 25-OH vitamin D) were measured in blood serum by ELISA. Risk factors for reducing BMD were identified using multivariate regression analysis and receiver operating characteristic (ROC) curves. RESULTS: Among patients with diabetes, 49 individuals had normal BMD and 33 showed decreased T-score values (<-1 SD). Free testosterone <5.92 pg/ml was predictor for decreased BMD at the lumbar spine (OR=4.4, p=0.04). For femoral neck, the risk factors were body weight <95.5 kg (OR=2.8, p=0.04), total fat mass <27 kg (OR=3.3, p=0.03), truncal fat mass<17.5 kg(OR=4.5, p=0.006), android (central abdominal) fat mass <3.2 kg(OR=4.0, p=0.01), gynoid (hip) fat mass <3.5 kg(OR=3.3, p=0.02), and lean mass <59 kg(OR=3.0, p=0.04). Risk factors for reduced BMD at the forearm were diabetes duration>15.5 years (OR=3.7, p=0.03) and HbA1c <8.15% (OR=3.8, p=0.03). Parathyroid hormone and 25-OH-vitamin D did not predict BMD independently. CONCLUSIONS: In men with type 2 diabetes, low free testosterone is a risk factor for decreased BMD in the lumbar spine, and diabetes duration is a risk factor for decreased BMD in the forearm. The presence of obesity is associated with an increase in BMD in the femoral neck; a high HbA1c is associated with an increase in BMD in the forearm.
We experimentally and numerically study the dynamics of whispering gallery modes slowly propagating within the cladding of an optical fiber near its end facet.

We demonstrated that modes reflect from the fiber cleave. The reflection coefficient appears to reach 70% for the sample under study.

Use of a facet provides a simple method to confine the axial propagation of the modes.
The expression of eukaryotic genes can be regulated at several stages, including the translation of mRNA. It is known that the structure of mRNA can affect both the efficiency of interaction with the translation apparatus in general and the choice of translation initiation sites.

To study the translated fraction of the transcriptome, experimental methods of analysis were developed, the most informative of which is ribosomal profiling (RP, Ribo-seq). Originally developed for use in yeast systems, this method has been adapted for research in translation mechanisms in many plant species. This technology includes the isolation of the polysomal fraction and high-performance sequencing of a pool of mRNA fragments associated with ribosomes. Comparing the results of transcript coverage with reads obtained using the ribosome profiling with the transcriptional efficiency of genes allows the translation efficiency to be evaluated for each transcript. The exact positions of ribosomes determined on mRNA sequences allow determining the translation of open reading frames and switching between the translation of several reading frames - a phenomenon in which two or more overlapping frames are read from one mRNA and different proteins are synthesized. The advantage of this method is that it provides quantitative estimates of ribosome coverage of mRNA and can detect relatively rare translation events.

Using this technology, it was possible to identify and classify plant genes by the type of regulation of their expression at the transcription, translation, or both levels. Features of the mRNA structure that affect translation levels have been revealed: the formation of G2 quadruplexes and the presence of specific motifs in the 5'-UTR region, GC content, the presence of alternative translation starts, and the influence of uORFs on the translation of downstream mORFs. In this review, we briefly reviewed the RP methodology and the prospects for its application to study the structural and functional organization and regulation of plant gene expression.
Male populations in the European North of Russia have not previously been investigated for semen quality. The aim of this study was to evaluate semen parameters, reproductive hormone levels, and lipid levels in volunteers from the general urban population of the European North of Russia, to compare the data published for men from the neighboring Northern or Eastern European countries, and to evaluate associations between sperm quality and serum hormonal and lipid levels. Ninety-nine volunteers aged 23–63 years residing in the city of Archangelsk were enrolled in the study. All men had blood samples drawn and completed a questionnaire concerning their health status and lifestyle; 90 men delivered semen samples. The medians for semen volume, sperm concentration, progressive motility, and normal morphology were 3.0 ml, 42.12 million/ml, 43.8%, and 6.5%, respectively. Sperm parameters below normal threshold values were found in 38.9% of participants. It seems that the sperm quality in our study group was slightly worse than in men from Finland, Norway, Sweden, or Estonia, but very similar to that in men from Denmark or Poland. The significant negative correlations of luteinizing hormone levels and positive correlations of inhibin B levels with sperm concentration and progressive motility were revealed. Higher levels of luteinizing hormone and lower levels of inhibin B were found in participants with impaired compared to normal sperm quality. No reliable links were found between serum total cholesterol, triglyceride, high and low-density lipoprotein cholesterol, and semen parameters.
GlideinWMS is a workload management and provisioning system that allows sharing computing resources distributed over independent sites. Based on the requests made by GlideinWMS frontends, a dynamically sized pool of resources is created by GlideinWMS pilot factories via pilot job submission to resource sites’ CEs. More than 400 CEs are currently serving more than ten virtual organizations through GlideinWMS, with CMS being the biggest user with 230 CEs. The complex configurations of the parameters defining resource requests, as submitted to those CEs, have been historically managed by manually editing a set of different XML files. New possibilities arise with CMS adopting the CRIC, an information system that collects, aggregates, stores, and exposes, among other things, computing resource data coming from various data providers. The paper will describe the challenges faced when CMS started to use CRIC to automatically generate the GlideinWMS factory configurations. The architecture of the prototype, and the ancillary tools developed to ease this transition, will be discussed. Finally, future plans and milestones will be outlined.
We report on the first BaGa4Se7 nanosecond optical parametric oscillator pumped by Q-switched Nd:YLiF4 laser at 1053 nm. The oscillator exhibits a pump threshold energy as low as 0.25 mJ. Mid-infrared (MIR) idler wave tuning from 2.6 μm to 10.4 μm is demonstrated with an angle-tuned type-I (o-ee) y-cut sample, highlighting the superior performance of this novel large bandgap chalcogenide nonlinear crystal to generate tunable coherent radiation over its full MIR transparency range (0.47–18 μm). The phase-matching data are used to identify the most accurate dispersion relations of this compound among three recently published Sellmeier equations. Damage threshold measurements yielded values as high as 2.04 J cm−2 at 100 Hz pulse repetition rate, one of the largest among existing MIR χ(2)nonlinear materials.
In the contract on rendering of services obligations occurs and is formed by the contract of compensated rendering of services. As a rule, the contract of civil paid services is a new type of contract in civil law, which is referred to in article 683 of the Civil code of the Republic of Kazakhstan. Terms of paid services include: telecommunications, medical services, veterinary medicine, audit, consulting, advertising, information, educational services, travel services, etc.in accordance with the agreement on paid services, the contractor undertakes to provide services on behalf of the customer, that is, to take certain actions or perform certain actions, and the customer undertakes to pay for it. Fees paid for these services under Soviet law are recognized as illegal profits and are not supported by the state. Legal support was provided when these services were transferred to the new economic relations and after the adoption of the Special part of the joint service of Kazakhstan. Depending on the nature of the adjustment, these terms are set out in the contract terms and conditions of service.In the future, taking into account the stable development of the market of services, it can be assumed that the service contract in the future will be one of the most popular and dynamically developingcivil law institutions.Key words: services, paid services, obligation, contractor, customer, contract.
1D grooved metal gratings are actively used in the terahertz plasmonics for excitation of surface plasmon polaritons (SPPs). SPPs are traveling charge density waves at the surface of conducting materials. Since these modes have a non-radiative nature, they can be excited only if the configuration meets the wavevector-matching condition for the incident light and SPP dispersion law. The wavelength gratings are the most suitable and cheapest solution to satisfy this requirement. Thorough optimization of the most suitable experimental parameters via numerical simulations leads to the enhancement of surface plasmon resonance response. In this paper, the numerical results of the optimization of gratings with different groove profiles are discussed.
Comparison of the two laser sources (UV nanosecond and IR femtosecond) used for the formation of micro-relief at the silicon surface showed the advantage of the second one.

A four-level silicon diffractive THz Fresnel lens has been fabricated by laser ablation at high repetition rate (f = 200 kHz) of femtosecond Yb:YAG laser. Features of the lens were investigated in the beam of the Novosibirsk free electron laser at the wavelength of 141 μm.

Detailed results of investigation of fabricated lens micro-relief are presented. The measured diffractive efficiency of the lens is in good agreement with the theoretical prediction.
One of the core symptoms of major depression in human is anhedonia. For that reason, one of the main requirements towards experimental depression models is that they be able to demonstrate anhedonia in animals, that have been exposed to stressful events, and other behavioral changes attributable to a depression-like state. However, the results presented in the literature are contradictory: sweet solution intake, which is considered as a parameter of hedonic/anhedonic behavior in animals, responds quite differently to stressful situations in that it is either unaffected or increased or decreased.

Different experimental designs used for the study of anhedonia in male mice exposed to chronic social defeat stress were tried to understand the reasons for so contradictory responses. Anhedonia appears as an abrupt reduction in sweet solution consumption in stressed animals and by failure to attain recovery after deprivation. However, it was also demonstrated that sucrose solution intake and preference strongly depend on the experimental context; that the possible critical factor may be prior acquaintance with the hedonic stimulus – or the lack whereof.

Analysis of literature data and ours allowed us to conclude that the lack of a significant decrease in sweet solution intake in stressed animals is no evidence of lack of depression. This decrease is evidence of anhedonia only provided other symptoms of depression are present. Hedonic consumable intake can be decreased over various motivations, conditions or diseases, in particular, a high level of anxiety or pathological aggression.
Simulations of proton-driven plasma wakefield accelerators have demonstrated substantially higher accelerating gradients compared to conventional accelerators and the viability of accelerating electrons to the energy frontier in a single plasma stage. However, due to the strong intrinsic transverse fields varying both radially and in time, the witness beam quality is still far from suitable for practical application in future colliders.

Here we demonstrate efficient acceleration of electrons in proton-driven wakefields in a hollow plasma channel. In this regime, the witness bunch is positioned in the region with a strong accelerating field, free from plasma electrons and ions.

We show that the electron beam carrying the charge of about 10% of 1 TeV proton driver charge can be accelerated to 0.6 TeV with preserved normalized emittance in a single channel of 700 m. This high quality and high charge beam may pave the way for the development of future plasma-based energy frontier colliders.
In spite of remarkable progress in the development of catalytic systems for oxidation at mild conditions, their application and further development are limited by the absence of cheap sources of reduced oxygen forms (H 2 O 2 , NaOCl, etc).The in situ generation of hydrogen peroxide is very promising to resolving this problem.It is suggested an approach based on in situ production of diluted hydrogen peroxide solutions from air oxygen in a new type electrochemical reactor with a swirled fluidized bed electrode for carrying out oxidative reactions with organic compounds.The reactor allows to process simultaneously the oxidant production and the oxidative reactions and to utilize entire reaction volume in contrast to electrochemical reactors with flat electrodes geometry.Reactor permits to use a variety of homogeneous and heterogeneous catalytic systems which require hydrogen peroxide.
Studies that track and compiled transformations of ilmenite and magnetite under conditions of different metamorphic grades are still very limited. The Sedova Zaimka intrusion in Western Siberia (Russia) is a good example to examine the effect of contact metamorphism from greenschist to low-amphibolite facies on magmatic Fe-Ti oxide minerals, as this small mafic-ultramafic body is located within contact metamorphic aureole of a large granite pluton. In the Sedova Zaimka, ilmenite with little to no magnetite is present as an accessory dissemination throughout metamorphosed rocks. Ilmenite is variably enriched in MnO (1 to 13.3 wt%) and depleted in MgO (less than 0.3 wt%), suggesting that its primary magmatic composition has been unevenly modified by diffusion re-equilibrium with coexisting metamorphic silicates. The elevated content of ZnO (up to 0.5 wt%) and NiO (up to 0.4 wt%) in ilmenite suggests that both ZnO and NiO, like MnO, must be strongly partitioned into ilmenite relatively to silicate minerals under the reducing contact metamorphic conditions, if chromite is absent. The textural observations of ilmenite–sulfide and ilmenite–titanite–sulfide relationships indicate that Ti-magnetite, in contrast to ilmenite, is an unstable phase in the presence of sulfur-rich reduced metamorphic fluids and is completely replaced by sulfides, with the development of specific “octahedral meshes” of ilmenite in sulfides.
To simulate the interaction of a nanoparticle with an electron beam, we previously developed a theoretical description for the general case of a particle fully embedded in an infinite arbitrary host medium. The theory is based on the volume-integral variant of frequency-domain Maxwell’s equations and, therefore, is naturally applicable in the discrete-dipole approximation. The fully-embedded approximation allows fast numerical simulations of the experiments for particles inside a substrate since the host medium discretization is not needed. In this work, we study how applicable the fully-embedded approach is for realistic scenarios with relatively thin substrates. In particular, we performed test simulations for a silver sphere both inside an infinite host medium and inside a finite box or sphere. For the host medium, we considered two non-absorbing cases (the denser one causes Cherenkov radiation), as well as an absorbing case. The peak positions in the obtained spectra approximately agree between substrates a few times thicker than the sphere and the infinite one. However, a much thicker substrate (of the order of μm) would be required to have a qualitative agreement for absolute peak amplitudes. The developed algorithm is implemented in the open-source code ADDA, allowing one to rigorously and efficiently simulate electron-energy-loss spectroscopy and cathodoluminescence by particles of arbitrary shape and internal structure embedded into any homogeneous host medium.
