We establish Gr\"{o}bner-Shirshov bases theory for Gelfand-Dorfman-Novikov algebras over a field of characteristic $0$. As applications, a PBW type theorem in Shirshov form is given and we provide an algorithm for solving the word problem of Gelfand-Dorfman-Novikov algebras with finite homogeneous relations. We also construct a subalgebra of one generated free Gelfand-Dorfman-Novikov algebra which is not free.
The paper provides an overview of the results of multiyear joint researches of team of collaborators of Institute of Laser Physics SB RAS together with NF IRTC 'Eye Microsurgery' for the period from 1988 to the present

in which were first proposed and experimentally realized laser medical technologies for correction of refractive errors of known today as LASIK, the treatment of ophthalmic herpes and open-angle glaucoma. It is proposed to carry out operations for the correction of refractive errors the use of UV excimer KrCl laser with a wavelength of 222 nm. The same laser emission is the most suitable for the treatment of ophthalmic herpes, because it has a high clinical effect, combined with many years of absence of recrudescence. A minimally invasive technique of glaucoma operations using excimer XeCl laser (λ=308 nm) is developed.

Its wavelength allows perform all stages of glaucoma operations, while the laser head itself has high stability and lifetime, will significantly reduce operating costs, compared with other types of lasers.
Synaptonemal complex (SC) chains were revealed in semisterile intraspecific F1 hybrids of Ellobius tancrei Blasius, 1884 (2n = 49, NF=56 and 2n=50, NF=56), heterozygous for Robertsonian (Rb) translocations. Chains were formed by Rb submetacentrics with monobrachial homology.

Chromosome synapsis in spermatocytes of these hybrids was disturbed, apparently because of the problematic release of the chromosomes from the SC chains.

These hybrids suffer from low fertility, and our data support the opinion that this is because a formation of Rb metacentrics with monobrachial homology within different races of the same species might be an initial event for the divergence of chromosomal forms.
We report a comparative study of the binding of I2 (iodine) in a pair of redox-active metal-organic framework (MOF) materials, MFM-300(VIII) and its oxidized, deprotonated analogue, MFM-300(VIV).

Adsorption of I2 in MFM-300(VIII) triggers a host-to-guest charge-transfer, accompanied by a partial (∼30%) oxidation of the VIII centers in the host framework and formation of I3- species residing in the MOF channels. Importantly, this charge-transfer induces a significant enhancement in the electrical conductivity (Δσ = 700000) of I2@MFM-300(VIII/IV) in comparison to MFM-300(VIII). In contrast, no host-guest charge-transfer or apparent change in the conductivity was observed upon adsorption of I2 in MFM-300(VIV). High-resolution synchrotron X-ray diffraction of I2@MFM-300(VIII/IV) confirms the first example of self-aggregation of adsorbed iodine species (I2 and I3-) into infinite helical chains within a MOF.

This paper reviews a construction called iterant algebra that reconstructs Clifford algebra and matrix algebra from the point of view of the symmetric group acting on vectors as ordered lists of their components.

This algebraic background is then used to discuss

the braiding of Majorana Fermions, the structure of the Dirac equation and the form of the the version of the Dirac equation due to Majorana.
Transcripts of many enzymes involved in base excision repair (BER) undergo extensive alternative splicing, but functions of the corresponding alternative splice variants remain largely unexplored.

In this review, we cover the studies describing the common alternatively spliced isoforms and disease-associated variants of DNA glycosylases, AP-endonuclease 1, and DNA polymerase beta.

We also discuss the roles of alternative splicing in the regulation of their expression, catalytic activities, and intracellular transport.
Outbreaks of influenza, which is a contagious respiratory disease, occur throughout the world annually, affecting millions of people with many fatal cases. The D222G/N mutations in the hemagglutinin (HA) gene of A(H1N1)pdm09 are associated with severe and fatal human influenza cases. These mutations lead to increased virus replication in the lower respiratory tract (LRT) and may result in life-threatening pneumonia. Targeted NGS analysis revealed the presence of mutations in major and minor variants in 57% of fatal cases, with the proportion of viral variants with mutations varying from 1% to 98% in each individual sample in the epidemic season 2018–2019 in Russia. Co-occurrence of the mutations D222G and D222N was detected in a substantial number of the studied fatal cases (41%). The D222G/N mutations were detected at a low frequency (less than 1%) in the rest of the studied samples from fatal and nonfatal cases of influenza. The presence of HA D222Y/V/A mutations was detected in a few fatal cases. The high rate of occurrence of HA D222G/N mutations in A(H1N1)pdm09 viruses, their increased ability to replicate in the LRT and their association with fatal outcomes points to the importance of monitoring the mutations in circulating A(H1N1)pdm09 viruses for the evaluation of their epidemiological significance and for the consideration of disease prevention and treatment options.

In the present work a variation of schlieren technique increasing its sensitivity and usability is described. New self-adjustable adaptive transparencies (cutoffs) based on bleaching effect are suggested. The transparencies are thin layers made of translucent substance which are placed in the focal plane of the receiving lens of a shlieren system. To implement the technique laser light sources have to be used. It was shown the transparencies have low response time (10-20 µs) allowing significantly reduce liability of the system to vibrations. Such adaptive visualizing transparencies (AVT) have an increased sensitivity and usability and enable one to obtain a quantitative data.
Different generation modes of all-positive-dispersion all-fibre Yb laser mode-locked due to effect of non-linear polarization evolution are investigated. For the first time we realized in the same laser both generation of single picoseconds pulse train and a newly observed lasing regime where generated are picosecond wave-packets, each being a train of femtosecond sub-pulses. Using both experimental results and numerical modeling we discuss in detail the mechanisms of laser mode-locking and switching of generation regimes and show a strong dependence of output laser characteristics on configuration of polarization controllers. A good qualitative agreement between experimental results and numerical modeling is demonstrated.
Background Hypertension is recognized as an important contributor to high cardiovascular mortality in Russia. A comprehensive analysis of data from Russian studies that measured blood pressure in population-based samples has not been previously undertaken. This study aims to identify trends and patterns in mean blood pressure and the prevalence of hypertension in Russia over the most recent 40 years. Methods We obtained anonymized individual records of blood pressure measurements from 14 surveys conducted in Russia in 1975–2017 relating to a total of 137,687 individuals. For comparative purposes we obtained equivalent data from 4 surveys in the USA and England for 23,864 individuals. A meta-regression on aggregated data adjusted for education was undertaken to estimate time trends in mean systolic and diastolic blood pressure, the prevalence of elevated blood pressure (> 140/90 mmHg), and hypertension (defined as elevated blood pressure and/or the use of blood pressure-lowering) medication. A meta-analysis of pooled individual-level data was used to assess male-female differences in blood pressure and hypertension. Results During the period 1975–2017 mean blood pressure, the prevalence of elevated blood pressure and hypertension remained stable among Russian men. Among Russian women, mean systolic blood pressure decreased at an annual rate of 0.25 mmHg ( p < 0.1) at age 35–54 years and by 0.8 mmHg ( p < 0.01) at ages 55 and over. The prevalence of elevated blood pressure also decreased by 0.8% per year ( p < 0.01), but the prevalence of hypertension remained stable. Mean blood pressure and prevalence of hypertension were higher in Russia compared to the USA and England at all ages and for both sexes. Conclusions In contrast to the generally observed downward trend in elevated blood pressure in many other countries, levels in Russia have changed little over the past 40 years, although there are some positive trends among women. Improved strategies to bring down the high levels of mean blood pressure and hypertension in Russia compared to countries such as England and the USA are important to further reduce the high burden of CVD in Russia.

One of the reasons for changes in translation of such sentences, as it seems to us, is the fact that standard characterization schemes in Russian and German have different semantic potentials, that is, meanings that can be implicitly represented in the characterization structure of one language cannot be rendered by a similar structure in another. The purpose of this contrastive study is therefore to find out how identical the characterization structures in Russian and German are from the point of view of semantic potential.

To achieve this goal, we analyze the causes of changes in rendering attributive characterization in translation. We apply a structural-semantic approach in a comparative examination of Russian and German proposals for qualitative characterization. The novelty of the study is that we trace the process of this semantics’ formation in their non-standard structures, as well as in how expressivity is realized or maintained in the reviewed sentences. In the study, we used the method of continuous sampling of sentences and their translations from the Russian Language National Corpus. The structural-semiotic method allowed us to trace the process of characterization semantics formation in structures, which are usually used to express other meanings. Contextual and comparative methods allowed us to identify the causes of changes in the translation, and the method of quantitative analysis – the frequency of translation transformations. Using interlinear and reverse translations, differences in the structure and semantics of the original and translated sentences were shown.

We found that the proposition of attributive characterization is expressed in a non-standard way in translations only in a small percentage of instances, which is mainly due to the difference in the stylistic norms of languages, and in some cases, to the difference in the semantic potential of the characterization structure. In particular cases, the Russian structure is capable of implicitly expressing the metaphor of the feature presented in it, which in the German translation requires explication, and, accordingly, a change in the way of its rendering. Along with the semantic changes accompanying the substitution of the structure, we revealed a decrease in the categorization of the attribute, creation of a more “lively” image, intensification of an attribute, strengthening of its static character, putting the reader closer to the point of view of the narrator.
Hydrogenation of γ-valerolactone (GVL) in polar solvents (n-butanol, 1,4-dioxane) to 1,4-pentanediol (PDO) and 2-methyltetrahydrofuran (MTHF) was performed at 363–443 K in a fixed bed reactor under overall H2 pressure of 0.7–1.3 MPa. Preliminary screening in a batch reactior was performed with a series of Ru, Ir, Pt, Co, and Cu catalysts, earlier efficiently applied for levulinic acid hydrogenation to GVL. The fresh catalysts were analyzed by transmission electron microscopy (TEM), X-ray fluorescent analysis (XRF), temperature programmed reduction by H2 (H2-TPR), and N2 physisorption. Cu/SiO2 prepared by reduction of copper hydroxosilicate with chrysocolla mineral structure provided better selectivity of 67% towards PDO at 32% GVL conversion in a continuous flow reactor. This catalyst was applied to study the effect of temperature, hydrogen pressure, and contact time. The main reaction products were PDO, MTHF, and traces of pentanol, while no valeric acid was observed. Activity and selectivity to PDO over Cu/SiO2 did not change over 9 h, indicating a fair resistance of copper to leaching.
We discuss some problems concerning the application of perturbative QCD to high energy soft processes. We show that summing the contributions of the lowest twist operators for non-singlet $t$-channel leads to a Regge-like amplitude. Singlet case is also discussed.
Настоящий обзор освещает последние тенденции в области психолого-педагогических вмешательств для детей с расстройствами аутистического спектра (РАС) с учетом стремительного роста числа публикаций по этой тематике в последние несколько лет. В настоящий момент внимание специалистов в области вмешательств при РАС сосредоточено на соблюдении стандартов научной доказательности и высоком качестве исследований. Согласно недавним систематическим обзорам, все комплексные программы вмешательства для детей с РАС с доказанной эффективностью в той или иной степени основаны на научной дисциплине прикладного анализа поведения (ПАП). Реализация таких интенсивных поведенческих программ улучшает траекторию развития ребенка с РАС. В частности, метааналитические исследования демонстрируют существенное улучшение показателей IQ и адаптивного поведения у детей, помощь которым оказывалась в рамках ранних интенсивных комплексных программ, основанных на ПАП. Более того, большинство целевых вмешательств с доказанной эффективностью для детей с РАС либо также основаны на ПАП, либо являются компонентами комплексных программ вмешательств, основанных на ПАП. В последнее время возрастает интерес к модульным вмешательствам, которые позволяют обеспечить высокую степень индивидуализации программы помощи для каждого ребенка с РАС, в то же время удовлетворяя стандартам научной доказательности. Рост числа строгих оценок эффективности различных вмешательств, применяемых в реальных неклинических условиях для компенсации основных дефицитов, связанных с РАС, создает адекватную базу для внедрения и широкого использования вмешательств с доказанной эффективностью в системе помощи людям с РАС, в том числе неспециалистами, прошедшими базовую подготовку.
The reflection of probe infrared femtosecond radiation pulses from a gallium arsenide substrate of the (001) orientation in the presence of more powerful pump pulses of the same radiation with a peak power of up to 1 GW/cm2 was investigated. A Yb3+:KY(WO4)2 laser with a central wavelength of 1 035 nm, a repetition rate of 70 MHz, a pulse duration of 130 fs, and an average power of not more than 0.9 W worked in the GaAs transparency region. The experimental dependence of the recorded signal on the pump radiation intensity is in qualitative agreement with the model dependence for two-photon absorption. The results are important for the correct interpretation of reflectivity kinetics of quantum wells.
The results of cartographic modeling of the temperature fields of soils of the land fund of the Novosibirsk region using satellite data obtained by the MODIS/Terra spectroradiometer are considered. The developed cartographic models give a clear idea of the spatial structure of the temperature fields of the soil cover of the Novosibirsk region and the qualitative changes in the temperature regime of soils in different years. According to the data of daytime and nighttime surveys, the peculiarities of the temperature distribution of the soil cover for 2001 and 2010 were established. The values of the average annual temperature of the underlying surface for 2001–2014 were calculated. It is assumed that thermal resources not reflected in the generalization of zonal zoning can be identified on cartographic models. These resources have independent ecological significance and characterize the diversity of landscape, anthropogenic and other types of climate.
Background: There is ample experimental evidence supporting the hypothesis that the brain serotonergic system is involved in the control of chronic social defeat stress (CSDS), depression and anxiety. The study aimed to analyze mRNA levels of the serotonergic genes in the raphe nuclei of the midbrain that may be associated with chronic social defeats consistently shown by male mice in special experimental settings.Methodology/Principal Findings:The serotonergic genes were the Tph2, Sert, Maoa and Htr1a. The Bdnf, Creb, Cphn, Gapdh, Hprt, B2M, 18S and Actb genes were also studied. The experimental groups were composed of male mice with experience of defeats in 21 daily encounters and male mice with the same track record of defeats followed by a no-defeat period without agonistic interactions (relative rest for 14 days). It has been shown that mRNA levels of the Tph2, Maoa, Sert, Htr1a, Bdnf and Creb genes in the raphe nuclei of defeated mice are decreased as compared with the controls. Under CSDS the Cphn, Gapdh, Hprt, B2M, 18S, Actb genes are also down-regulated. The expression of the serotonergic genes as well as the Cphn and Creb genes is not restored to the control level after the 2 weeks of relative rest. mRNA levels of other genes are not recovered to the control levels, although some up-regulation was observed in rested losers. Significant positive correlations were found between the total time of avoidance behavior demonstrated by the 21-day defeaters in agonistic interactions and Sert, Maoa, Bdnf, Gapdh and 18S mRNA levels. Conclusions: CSDS experience inducing the development of mixed anxious/depression-like state in male mice down-regulates the serotonergic genes expression associated with the synthesis, inactivation and reception of serotonin. The Bdnf and Creb genes as well as the cell and metabolic Cphn, Gapdh, Hprt, B2M, Actb and 18S genes in the midbrain raphe nuclei are also down-regulated under CSDS. Period of relative rest is not enough for most genes to recover expression to the control levels.
The article deals with the contradictions of two forms of dealing with the past – history and memory. Based on the analysis of the concept of the 20th century classic Paul Ricoeur, it is shown how memory can turn from a testimonial of experience into a substitution of the past in the form of a 'obligated memory'.

The idea of 'obligated memory' is considered on the example of the ideologeme of victory in the Russian politics of memory, which obscures the experience of grief and destruction suffered by the victorious people.

It is shown that 'obligated memory' only seems to be memory, thereby forcing one to take its images seriously, but it does not rely on real experience, which is necessary for the survival as of individuals so of societies as a whole.
