The article deals with the importance of a modern university teacher (and mentor) for the future students who will help them to become a qualified candidate in the chosen specialty. As the title implies, the article describes the leadership skills of a mentor, his knowledge and his attitude to work. The aim of the article is to show that the teacher (mentor) has to be constantly developing and take additional courses, lectures, and engage in self-development. Much attention is given to communication with students and the personality of a teacher and such features as sense of humor, responsibility, independence, kindness and so on. The results show that the successful mentor should completely trust students, learn from them and help students to identify their weaknesses and get rid of them as well as develop his own soft skills. Summing up the results, it can be concluded that a successful modern teacher (mentor) must keep up with modern changes of education and be creative, smart, charismatic and thirsty for the knowledge as well as to be a good psychologist. Higher education teachers should constantly undergo additional retraining, and remain a person-example for students who is interesting to listen to and who can be trusted.
The current coverage of oil wells with telemetry does not allow timely determination of deviations in the operation of about 40% of electric submersible pumps. To solve this problem, a model of virtual sensors has been developed that allows the prediction of temperature and pressure growth at the pump intake in the absence of submersible sensors based on modern big data processing and machine learning technologies. The developed models of virtual sensors are embedded directly into the process control system, which allows notifying the technologists and operators about a possible reduction in the planned average pump operating time and their possible failures for various reasons.
These differ from dehalogenation of related (aza) aromatics (e.g.benzenes, naphthalenes, quinoxalines).

At the first stage of electrochemical reduction in DMF, fluorinated/chlorinated 2,1,3-benzothia/selenadiazoles formed long-lived radical anions characterized by EPR and DFT.Gas-phase electron affinities (EA1) from DFT correlated well with the first-peak potentials separately for S and Se derivatives, and the latter were found to be better electron acceptors than the former in contrast to the atomic EA1 and Allen electronegativity.At the second stage, chalcogen-and halogen-dependent dehalogenation proceeded: non-hydrodefluorination of selenadiazoles through their n-electron activation (n ≥ 2), and hydrodechlorination of thia/selenadiazoles through H + addition to their dianions.

At the second stage, chalcogen-and halogen-dependent dehalogenation proceeded: non-hydrodefluorination of selenadiazoles through their n-electron activation (n ≥ 2), and hydrodechlorination of thia/selenadiazoles through H + addition to their dianions.These differ from dehalogenation of related (aza) aromatics (e.g.benzenes, naphthalenes, quinoxalines).
In this work, mathematical modelling of the process of rupturing the wall of a human fusiform aneurysm is carried out. We consider 3-parameter and 5-parameter Mooney-Rivlin models. The comparison between the results of the modelling and the experimental data is made. Analyzing the relation of parameters of 3-parameters and 5-parameters Mooney-Rivlin models, the relation between the greatest (least) value and Cauchy strain was found. The field of application of these models for hemodynamics was shown.
Rational synthesis of a series of new heterometallic MOFs was carried out by the judicious choice of the corresponding pivalate complexes [Li2M2(piv)6(py)2] (M = Zn2+, Co2+, piv- = pivalate anion and py = pyridine) as a source of secondary building units, {LiM(O2CR)3} and an organic tricarboxylate linker as a node defining the dimensionality of the framework by the orientation of the carboxylic group in or out of the central aromatic ring plane. Thus the trimesate (btc3-) linker results in 3D srs topology frameworks with intersecting systems or isolated channels, and 1,3,5-benzenetribenzoate (btb3-) results in layered hcb isostructural compounds additionally stabilized with H-π interactions between the layers. The layered compounds demonstrate a permanent porosity with a BET surface area of up to 688 m2·g-1 with the possibility of selective gas adsorption (CO2 over N2 and CH4). Zn-Based coordination polymers show notable color changes and drastic (up to 30 times) quenching of luminescence upon inclusion of different nitroaromatics.
Serpentinization is an important post-magmatic process in spreading and subducted zones. This process is the cause of the remobilization and redistribution of highly mobile elements, platinum group elements (PGE) and base metals.

Secondary platinum group minerals (PGMs) formed because of PGE remobilization under the action of mantle and crustal fluid on the rocks. The formation of the secondary PGMs can occur in several stages. Under the effect on the chromitites of reduced mantle fluids, native PGE alloys were formed during early serpentinization. Under dehydrating subducted slab fluid phase was caused in serpentinization mantle peridotites and have been dissolved magmatic high-temperature platinum group minerals.

During the obduction of ophiolites, an inversion from reducing to oxidizing condition took place with the formation of nickel arsenides and As, Sb – bearing PGMs.
If torsion exists, it generates gravitational four-fermion interaction (GFFI). This interaction gets dominating on the Planck scale. If one confines to the regular, axial-axial part of this interaction, the results do not comply with the Friedmann-Lemaitre-Robertson-Walker (FLRW) cosmology for the spatial flat or closed Universe. In principle, the anomalous, vector-vector interaction could restore the agreement.
Nowadays researchers provide more and more evidence that it is necessary to develop an ecologically friendly approach to pest control. This is reflected in a sharp increase in the value of the biological insecticide market in recent decades.

In our study, we found a virus strain belonging to the genus Cypovirus (Reoviridae); the strain was isolated from Dendrolimus sibiricus: that possesses attractive features as a candidate for mass production of biological agents for lepidopteran-pest control. We describe morphological, molecular, and ecological features of the new Cypovirus strain. This strain was found to be highly virulent to D. sibiricus (half-lethal dose is 68 occlusion bodies per second-instar larva) and to have a relatively wide host range (infects representatives of five families of Lepidoptera: Erebidae, Sphingidae, Pieridae, Noctuidae, and Lasiocampidae). The virus strain showed a strong interaction with a nontoxic adjuvant (optical brightener), which decreased the lethal dose for both main and alternative hosts, decreased lethal time, and may expand the host range. Moreover, we demonstrated that the insecticidal features were preserved after passaging through the most economically suitable host.

By providing strong arguments for possible usefulness of this strain in pest control, we call on virologists, pest control specialists and molecular biologists to give more attention to the Cypovirus genus, which may lead to new insights in the field of pest control research and may provide significant advantages to compare with baculoviruses and Bacillus thuringiensis products which are nowadays main source of bioinsecticides. Significance statement Within this article we are describing unique set of features of newly discovered cypovirus strain which possess by significant premises for modern biological insecticides requirements: high potency, universality, true regulating effect, flexible production (possibility to choose host species for production), interaction with enhancing adjuvants, ecologically friendly. Basing on genome alignment we suggest that increasing of host range of new strain is the sequence of evolutionary event which was occurred after coinfection of different CPV species within same host. This finding open new perspective to consider CPVs as perspective agent of biocontrol products.
We consider within QCD collinear factorization the process p + p → jet + jet + X, where two forward high-pT jets are produced with a large separation in rapidity Δy (Mueller-Navelet jets [1]).

The hard part of the reaction receives large higher-order corrections ∼ αns (Δy)n, which can be accounted for in the BFKL approach. We calculate cross section and azimuthal decorrelation, using the next-to-leading order jet vertices, in the small-cone approximation [2].
The paper is focused on light scattering by aggregates of optically soft particles with a size larger than the wavelength, in particular, blood platelets. We conducted a systematic simulation of light scattering by dimers and larger aggregates of blood platelets, each modeled as oblate spheroids, using the discrete dipole approximation. Two-dimensional (2-D) light scattering patterns (LSPs) and internal fields showed that the multiple scattering between constituent particles can be neglected. Additionally, we derived conditions of the scattering angle and orientation of the dimer, under which the averaging of the 2-D LSPs over the azimuthal scattering angle washes out interference in the far field, resulting in averaged LSPs of the aggregate being equal to the sum of that for its constituents. We verified theoretical conclusions using the averaged LSPs of blood platelets measured with the scanning flow cytometer (SFC). Moreover, we obtained similar results for a model system of aggregates of polystyrene beads, studied both experimentally and theoretically. Finally, we discussed the potential of discriminating platelet aggregates from monomers using the SFC.
The article reviews the history of the founding of Novosibirsk State University in the context of the first years of Akademgorodok in Novosibirsk, the largest scientific center in the eastern part of Russia. It describes the logic of the formation of a system for training researchers: physic and mathematic School – University – institutes of the Siberian Branch of the Russian Academy of Sciences. The main characteristics of the principle "education through research" are presented along with the current status of the University and plans for the future.
In this paper, the results of numerical calculations of a vapor bubble growth in superheated water at different pressures are presented. Modeling is based on a previously developed by the authors semi-analytical solution. The results are verified by experimental data obtained at atmospheric and subatmospheric pressures. The presented simulation results and experimental data are in good agreement. The advantage of the solution over the earlier ones (based on the thermal growth model) is shown.
In this work, numerical and analytical solutions of heat transfer in a dielectric layer during melting in the microwave field were considered.

We considered solutions, where the source term was obtained based on the solution of Maxwell equation, as well as using the Lambert law. The conditions applicable for analytical solutions, allowing the parametric analysis, are determined.

The areas of application of the technology of microwave melting of dielectrics, in particular with melting ice on water, defrosting products, etc., were also considered.
Let G be a locally finite group and let F ⁢ ( G ) {F(G)} be the Hirsch–Plotkin radical of G . Let S denote the full inverse image of the generalized Fitting subgroup of G / F ⁢ ( G ) {G/F(G)} in G . Assume that there is a number k such that the length of every nested chain of centralizers in G does not exceed k . The Borovik–Khukhro conjecture states, in particular, that under this assumption, the quotient G / S {G/S} contains an abelian subgroup of finite index bounded in terms of k . We disprove this statement and prove a weak analogue of it.
A polynomial-time algorithm is constructed that, given a graph $\Gamma$, finds the full set of nonequivalent Cayley representations of $\Gamma$ over the group $D\cong C_p\times C_{p^k}$, where $p\in \{2,3\}$ and $k\geq 1$. This result implies that the recognition and isomorphism problems for Cayley graphs over $D$ can be solved in polynomial time.
The possibility of using of pulsed supersonic gas jets for the formation of high intensity cluster ion beams are discusses. The results of experimental investigations of pulsed gases expansion are generalized in terms of dimensionless similarity parameters. The results of the experimental study of formation of an high-intensity cluster beam of argon are presented. The fundamental phenomenon influences on the main parameters of cluster beam (cluster size, intensity ect.) are considered.
The cathode was initially activated to a state of negative electron affinity in our photocathode preparation facility, achieving a quantum efficiency of 3% at a wavelength of 532 nm.

We present measurements of the transverse and longitudinal energy spread of photoelectrons emitted from a GaAsP photocathode as a function of its degradation state. It was then transferred under XHV conditions to our transverse energy spread spectrometer, where energy spread measurements were made while the photocathode was progressively degraded through a controlled exposure to oxygen. Data have been collected under photocathode illumination at 532 nm, and the changing photoelectron energy distribution associated with the changes in the level of electron affinity due to quantum efficiency degradation through an exposure to 0.25 L of oxygen has been demonstrated.

Our experiments have shown that GaAsP boasts a significantly higher resilience to degradation under exposure to oxygen than a GaAs photocathode, though it does exhibit a higher level of mean transverse energy. Coupled with the favourable published data on GaAsP photoemission response times, we conclude that GaAsP is a viable candidate material as a particle accelerator electron source.
We report on the examination of several approaches to simulate computationally the unstable regime of a model Kaplan turbine operating at off-design load.

Numerical simulations complemented by laboratory experiments have been performed for a 60:1 scaled-down laboratory turbine model using two Reynolds-averaged Navier–Stokes (RANS) models (linear eddy viscosity model (LEVM), and a Reynolds stress model (RSM), including realizable , k-ω SST, and LRR), detached eddy simulation model (DES), and large eddy simulation model (LES).

Unlike the LEVM, the RSM, DES, and LES reproduced the mean velocity components and the intensities of their fluctuations and pressure pulsations well. The underperformance of the LEVM is attributed to the high eddy viscosity as a consequence of an excessive production of the turbulent kinetic energy due to the models' inability to account for the turbulent stress anisotropy and the stress-stain phase lag, both naturally accounted for by the RSM. This led to a much larger modelled and a smaller resolved turbulent kinetic energy compared to those in the RSM.
Senescence-accelerated OXYS rats are an experimental model of accelerated aging that was established from Wistar stock via selection for susceptibility to cataractogenic effects of a galactose-rich diet and via subsequent inbreeding of highly susceptible rats. Currently, we have the 102nd generation of OXYS rats with spontaneously developing cataract and accelerated senescence syndrome, which means early development of a phenotype similar to human geriatric disorders, including accelerated brain aging.

In recent years, our group found strong evidence that OXYS rats are a promising model for studies of the mechanisms of brain aging and neurodegenerative processes similar to those seen in Alzheimer disease (AD). The manifestation of behavioral alterations and learning and memory deficits develop since the fourth week of age, i.e., simultaneously with first signs of neurodegeneration detectable on magnetic resonance imaging and under a light microscope. In addition, impaired long-term potentiation has been demonstrated in OXYS rats by the age of 3 months. With age, neurodegenerative changes in the brain of OXYS rats become amplified. We have shown that this deterioration happens against the background of overproduction of amyloid precursor protein (AβPP), accumulation of β-amyloid (Aβ), and hyperphosphorylation of the tau protein in the hippocampus and cortex. The development of AMD-like retinopathy in OXYS rats is also accompanied by increased accumulation of Aβ in the retina.

These published data suggest that the OXYS strain may serve as a spontaneous rat model of AD-like pathology and could help to decipher the pathogenesis of AD.
In this paper, wave modes are modeled for a countercurrent flow of vertically falling liquid film and turbulent gas. In the case of small Reynolds numbers for long wave perturbations, the problem is reduced to a nonlinear integro-differential equation for the film thickness deviation from the undisturbed level. Solutions of this model equation are studied. Several typical scenarios for the evolution of periodic perturbations are presented
Epoxidation of propylene into propylene oxide (PO) in the gas phase is a highly challenging reaction. Cu-based catalysts have been active for this reaction, but the state of Cu as an active species is still debatable. In this paper, we report the propylene epoxidation activity of solution combustion synthesized Cu/CeO2 catalysts with the CO + O2 mixture at low temperatures (50–100 °C) peaking at ∼80 °C. The highest PO yield was obtained with 20–25% Cu loading in CeO2. In contrast, the reaction over the catalyst containing nonreducible support such as Cu/SiO2 occurred above 170 °C. Detailed structural characterization indicated two types of Cu species such as Cu2+ partly (∼3%) dissolved in CeO2 forming a CuxCe1–xO2−δ phase and the remaining amount formed highly dispersed CuO as a separate phase. Thus, the highest activity relates to the optimum presence of CuO along with Ce1–xCuxO2−δ. The reducibility of the Cu species in two phases was significantly shifted toward lower temperatures, indicating strong electronic interaction between the two phases. The substituted Cu2+ was reduced first, and then, the bulk CuO reduction was initiated. In situ spectroscopic studies showed Cu+ formation from Cu2+ over Cu/CeO2 catalysts even at room temperature unlike in CeO2 or CuO + CeO2 physical mixtures, indicating strong electronic interaction between Ce1–xCuxO2−δ and CuO phases on CO adsorption in the Cu/CeO2 catalyst. It is proposed that substituted Cu2+ along with Ce4+ is reduced easily, and then, Ce3+ promotes the reduction of the interfacial CuO phase that might donate active oxygen species for epoxidation reaction.
Recent results from the KEDR detector obtained in the charmonium energy range are reported

We developed and implemented into software an algorithm for high-performance simulation of electrical logs from oil and gas wells using high-performance heterogeneous computing. The numerical solution of the 2D forward problem is based on the finite-element method and the Cholesky decomposition for solving a system of linear algebraic equations (SLAE). Software implementations of the algorithm used the NVIDIA CUDA technology and computing libraries are made, allowing us to perform decomposition of SLAE and find its solution on central processor unit (CPU) and graphics processor unit (GPU). The calculation time is analyzed depending on the matrix size and number of its non-zero elements. We estimated the computing speed on CPU and GPU, including high-performance heterogeneous CPU-GPU computing. Using the developed algorithm, we simulated resistivity data in realistic models.
Objective. To perform comparative analysis of the results of surgical treatment of patients with intervertebral disc herniation of different age groups. Material and Methods. The results of treatment of 2,448 patients (1,307 men and 1,141 women) with lumbar intervertebral disc herniation were analyzed. Out of them, 393 (16 %) people were elderly and senile patients with a mean age of 66 years. Evaluation of the treatment results in patients with herniated intervertebral discs was carried out in two groups: Group I – young and middle-aged patients; and Group II – elderly and senile patients. Mandatory preoperative evaluation included clinical and neurological examination, radiation diagnostic methods (X-ray, CT, CT-myelography, MRI), and survey using scales and questionnaires (VAS, ODI, CCI). Results. Body mass index (BMI), blood loss, duration of surgery, and length of hospital stay were statistically significantly greater in patients of Group II. In terms of pain, quality of life before and within 5 years after surgical treatment, patients of groups I and II have no statistically significant differences. The total complication rate was 4.9 %, while in patients of Group II complications developed statistically significantly more often (1.7 times) than in patients of Group I (p = 0.02). The most common complication was unintentional durotomy, which occurred in 3.6 % of cases, without statistically significant differences between groups. Epidural hematomas requiring revision intervention were observed in 13 patients, statistically significantly more often in patients of Group II (p = 0.04). The volume of blood loss in patients of Group II is significantly greater (p < 0.001). The cumulative index of reoperations over the 5-year follow-up period in Group I was 11.5 %, in Group II – 13.6 %. During the first year, reoperations in Group I amounted to 6.0 %, in Group II – 8.7 % (p = 0.05), which indicates the possible effect of age on the frequency of repeated operations. Convincing data on the effect of BMI and the comorbidity index on this indicator have not been obtained. The most common cause of reoperation in patients with herniated discs in both groups was hernia recurrence at the operated level, while the relapse rate in Group II was slightly higher – 46 % (n = 37) compared with 36 % (n = 168) in Group I. Conclusion. No difference was found between the clinical outcomes of surgical treatment of herniated intervertebral discs in patients of different age groups during a 5-year follow-up period. Elderly and senile age is a predictor of a higher frequency of early and intraoperative complications, an increase in the surgery duration and in the volume of intraoperative blood loss. Obesity and concomitant somatic pathology do not affect the clinical outcomes of surgical treatment and the cumulative index of repeated operations in patients with herniated discs of the lumbar spine.
