A measurement of off-shell Higgs boson production in the $ZZ\to4\ell$ and $ZZ\to2\ell2\nu$ decay channels, where $\ell$ stands for either an electron or a muon, is performed using data from proton-proton collisions at a centre-of-mass energy of $\sqrt{s}=13$ TeV. The data were collected by the ATLAS experiment in 2015 and 2016 at the Large Hadron Collider, and they correspond to an integrated luminosity of 36.1 fb$^{-1}$. An observed (expected) upper limit on the off-shell Higgs signal strength, defined as the event yield normalised to the Standard Model prediction, of 3.8 (3.4) is obtained at 95% confidence level (CL). Assuming the ratio of the Higgs boson couplings to the Standard Model predictions is independent of the momentum transfer of the Higgs production mechanism considered in the analysis, a combination with the on-shell signal-strength measurements yields an observed (expected) 95% CL upper limit on the Higgs boson total width of 14.4 (15.2) MeV.
It is widely suggested that a eukaryotic mRNA typically contains one translation start site and encodes a single functional protein product. However, according to current points of view on translation initiation mechanisms, eukaryotic ribosomes can recognize several alternative translation start sites and the number of experimentally verified examples of alternative translation is growing rapidly. Also, the frequent occurrence of alternative translation events and their functional significance are supported by the results of computational evaluations. The functional role of alternative translation and its contribution to eukaryotic proteome complexity are discussed. BioEssays 30:683–691, 2008. © 2008 Wiley Periodicals, Inc.
Suppose that L is one of the finite simple groups PSL 4 (q) or PSU 4 (q) and L acts on a vector space W over a field whose characteristic divides q.

We prove that the natural semidirect product of W and L contains an element whose order differs from the order of any element of L

An Important task in the treatment of oncological and neurodegenerative diseases is the search for new inhibitors of DNA repair system enzymes. Tyrosyl-DNA phosphodiesterase 1 (Tdp1) is one of the DNA repair system enzymes involved in the removal of DNA damages caused by topoisomerase I inhibitors. Thus, reducing the activity of Tdp1 can increase the effectiveness of currently used anticancer drugs. We describe here a new class of semisynthetic small molecule Tdp1 inhibitors based on the bile acid scaffold that were originally identified by virtual screening. The influence of functional groups of bile acids (hydroxy and acetoxy groups in the steroid framework and amide fragment in the side chain) on inhibitory activity was investigated. In vitro studies demonstrate the ability of the semisynthetic derivatives to effectively inhibit Tdp1 with IC50 up to 0.29 µM. Furthermore, an excellent fit is realized for the ligands when docked into the active site of the Tdp1 enzyme.
We describe a richly decorated iron helmet owned by the Moscow Kremlin Armoury. The specimen has never been analyzed in detail before. As we found out, it was one of the gifts sent by the Khotogoid Lama Erdene Dajan mergen Lanja to the Russian Tsar Mikhail Fyodorovich Romanov on 14 January, 1635. The helmet had been handed over to the State Treasury no later than 29 November, 1636, and later transferred to the Armoury. Apart from the helmet proper, the headgear in its initial condition includes a tripartite aventail made of narrow iron plates and decorated with colored velvet and silk, a cloth liner, and yellow satin ribbons, which were tied under the warrior’s chin. All the organic parts have been missing since the early 1700s. The dome of the helmet has a patterned applied strip and a visor with the Simhamukha Mantra written in Sanskrit and meant to protect the warrior from adverse charms and weapons. The technological analysis suggests that letters on the band were gilt, and those on the visor, silvered. Initially, the Armoury experts identifi ed the helmet as a “Manchu hat”. The typological analysis suggests that the headgear was made by Central Asian (Mongolian or Oirat) artisans in the late 16th or early 17th century. The specimen may be used as a standard for dating and attributing randomly found and unattributed battle and ceremonial headgears worn by late medieval and early modern Central Asian nomads.
Various clinical scenarios of the course of the post-COVID syndrome in the period of convalescence were studied. The frequency and volume of studies in combined pathology in patients who have undergone COVID-19 are considered. The controlled indicators of the medical state within the framework of follow-up monitoring and the minimum frequency of follow-up visits were clarified. Key words: New coronavirus infection, convalescents, the long COVID syndrome, follow-up monitoring
Three databases that provide data on transcriptional regulation are described. TRANSFAC is a database on transcription factors and their DNA binding sites. TRRD (Transcription Regulatory Region Database) collects information about complete regulatory regions, their regulation properties and architecture. COMPEL comprises specific information on composite regulatory elements.

Here, we describe the present status of these databases and the first steps towards their federation.
Применение современных оптико-электронных приборов расширяет возможности исследований в области экспериментальной механики жидкостей. Методы вычислительной фотографии за счет использования основанных на ней устройств постепенно проникают в различные области науки и техники. Камера светового поля может использоваться для регистрации трехмерных распределений скорости в потоках жидкости и газа там, где расположение нескольких панорамных оптических сенсоров затруднено за счет ограничения оптического доступа и вибраций.

В работе исследованы возможности пленоптической системы, состоящей из доступной на рынке промышленной камеры светового поля применительно для диагностики течений жидкости и газа. Предложен и протестирован новый программный алгоритм для вычисления карты глубины регистрируемой измерительной области.

Согласно полученным результатам, пространственное разрешение метода по глубине при использовании 11 мегапиксельного сенсора достигает 1/40 от глубины резкости оптической системы. Указанный метод был использован для измерения 3D-полей скорости турбулентной струи внутри щелевого канала по всей его глубине. В будущем количество задач, в которых целесообразно использование пленоптических устройств с высоким пространственным разрешением, будет расти.

In this paper a computer simulation of a blood flow in cerebral vessels with a giant saccular aneurysm at the bifurcation of the basilar artery is performed. The modelling is based on patient-specific clinical data (both flow domain geometry and boundary conditions for the inlets and outlets). The hydrodynamic and mechanical parameters are calculated in the frameworks of three models: rigid-wall assumption, one-way FSI approach, and full (two-way) hydroelastic model. A comparison of the numerical solutions shows that mutual fluid- solid interaction can result in qualitative changes in the structure of the fluid flow. Other characteristics of the flow (pressure, stress, strain and displacement) qualitatively agree with each other in different approaches. However, the quantitative comparison shows that accounting for the flow-vessel interaction, in general, decreases the absolute values of these parameters. Solving of the hydroelasticity problem gives a more detailed solution at a cost of highly increased computational time.
The distribution patterns of the X0/XX and neo-XY/neo-XX chromosome races, subraces, and "hybrids" between subraces of the grasshopper P. sapporensis were analyzed.

The origin of the observed variation is Robertsonian translocations between a sex chromosome and an autosome, and chromosome rearrangements. The fixation levels of inversions varied depending on geographic regions.

No hybrid population is known implying that a strong reproductive isolation system exists in hybrids between the different chromosomal races. The probable reasons for the purity of X0 and neo-XY chromosome races and high chromosome polymorphism in contact zones between chromosomal subraces are discussed. The presence of isolating barriers between chromosome races indicates a review of the taxonomic structure of P. sapporensis is required. It is proposed to divide P. sapporensis into two sibling species, which differ in the chromosome mechanisms of the sex determination system. The analysis of the distribution of chromosomal races and subraces of P. sapporensis allows a reconstruction of the history of this species in the Okhotsk sea region.
Modern ideas about socio-economic systems as systems of high complexity determine the search for management models that can develop adaptive properties to ensure their flexible maneuverability in an environment filled with fluctuations of different categories and uncertainty of the behavior of its subjects. Adaptation, according to the laws of evolution, is carried out within a certain limit, where actions are considered as a threshold response to changes. In the article, the limit is con sidered as a developing concept, starting from the philosophical interpretation, mathematical representation and purpose in management. Methods for determining the limit as a numerical sequence, represented as an information granule, using methods of mathematical statistics and fuzzy set theory are generalized. The causality of the transition from a feedback control model formed by significant deviations to a robust control model with predicted variants of the system maneuvering trajectory in the environment is revealed. A methodological approach to the definition of a robust limit as a numerical sequence (set), its structure, with the definition of a qualitative assessment of subsets in the contours of which a socio-economic system should exist and successfully develop with the use of a robust control mechanism, is presented.
Highly dispersed framework NZP-type zirconium phosphates were synthesized via both sol-gel method(SG)and mechanochemical activation(MA) of solid precursors followed by their hydrothermal treatment (HTT) in the presence of surfactants. Genesis of samples real structure and its effect on the surface properties and activity in hexane isomerization were studied.
Aquifers with waters characterized by low (< 0.2) to maximum saturation (0.8-1.0) with gases have been established within Cretaceous, Jurassic and Paleozoic deposits of the West Siberian sedimentary basin (WSSB), along with an increase in the saturation degree of formation waters with gases as the occurrence depth of reservoir intervals increases, and a relationship between gas saturation of formation waters and their total gas saturation value.

Computer simulation of physicochemical equilibria and evasion-invasion processes in the water-gas system enables modeling gas saturation degree variability and the physical nature of gaseous diffusion redistribution at the hydrocarbon accumulation – formation waters interface and in the transition zone from hydrocarbon accumulation to the peripheral waters.

All waters with total gas saturation exceeding 1.8 L/L become ultimately saturated with gases (Kg = 1.0), providing thereby theoretical prerequisites for the formation of hydrocarbon accumulations. The zone of Kg values spanning from 0.8 to 1.0 is associated with major gas condensate accumulations, while less saturated waters – with oil accumulations. The simulation results allow to assess the current state of the petroleum system of the West Siberian sedimentary basin, its part or a separate horizon within its limits, and to substantiate forecasts of its oil and gas potential at regional, zonal or local levels. The application of modeling techniques to water-gas equilibrium enables significant improvement of the reliability of oil and gas reserves assessment and largely contributes to the solution of problems with respect to searches of skipped accumulations in multi-reservoir fields during their further exploration.
The work is aimed at a detailed study of large-scale helical vortex structures emerging in a high turbulent intensively swirling flow.

It was shown that the vortex formed in the chamber by installing diaphragm with shifted outlet is folded into a single-helical vortex. The flow visualization shows that although the vortex axis performs slow oscillations (precession), on average this structure is fixed in space. The velocity fields were measured with the aid of a nonintrusive method of flow diagnostics (PIV). Verification of the calculation results obtained using a LES simulation was performed based on measured experimental data to confirm the correctness of the chosen mathematical modelling approach.

It has been asserted that the investigated regimes are in a self-similarity area relative to Reynolds number.
We construct a flexible (non-embedded) suspension with a hexagonal equator in Euclidean 3-space. It is known that the volume bounded by such a suspension is well defined and constant during the flex. We study its properties related to the Strong Bellows Conjecture which reads as follows: if a, possibly singular, polyhedron $\mathcal P$ in Euclidean 3-space is obtained from another, possibly singular, polyhedron $\mathcal Q$ by a continuous flex, then $\mathcal P$ and $\mathcal Q$ have the same Dehn invariants. It is well known that if $\mathcal P$ and $\mathcal Q$ are embedded, with the same volume and the same Dehn invariant, then they are scissors congruent.
Avian Influenza (AI) is a complex but still poorly understood disease; specifically when it comes to reservoirs, co-infections, connectedness and wider landscape perspectives. Low pathogenic (Low-path LP) AI in chickens caused by less virulent strains of AI viruses (AIVs)-when compared with highly pathogenic AIVs (HPAIVs)-are not even well-described yet or known how they contribute to wider AI and immune system issues. Co-circulation of LPAIVs with HPAIVs suggests their interactions in their ecological aspects.

Here we show for the Pacific Rim an international approach how to data mine and model-predict LP AI and its ecological niche with machine learning and open access data sets and geographic information systems (GIS) on a 5 km pixel size for best-possible inference. This is based on the best-available data on the issue (~ 40,827 records of lab-analyzed field data from Japan, Russia, Vietnam, Mongolia, Alaska and Influenza Research Database (IRD) and U.S. Department of Agriculture (USDA) database sets, as well as 19 GIS data layers). We sampled 157 hosts and 110 low-path AIVs with 32 species as drivers.

The prevalence across low-path AIV subtypes is dominated by Muscovy ducks, Mallards, Whistling Swans and gulls also emphasizing industrial impacts for the human-dominated wildlife contact zone. This investigation sets a good precedent for the study of reservoirs, big data mining, predictions and subsequent outbreaks of HPAI and other pandemics.
This review of the main publications about the problems of Japanese archaeology (from Paleolithic epoch up to the period of Kofun culture) represents teaching materials for students with specialty in archaeology (within the course «Archaeology of overseas Asia») and with specialty in oriental studies (within the course «History and culture of Japan»). Taking into account the main task of this publication – namely, support for educational process – authors of this review, first of all, engaged most authoritative summarizing editions, because their conceptions and conclusions passed through necessary approbation and were maintained by the greater part of academic community. The main problems under discussion in Japanese archaeology are as follows: chronology of the first inhabitation of Archipelago; classification of the stone implements according technologies of production and ways of usage; early ceramics in the context of Northeast Asian archaeology; the origin of Ainu and their predecessors; beginning of agriculture and development of bronze and iron metallurgy; semantics of dogu and haniva figurines; characteristics of megalithic monuments; attribution of «horse-rider culture»; correlation between ethno-linguistic and archaeological data; using of historical records for interpretation of excavated relics; the routes of ancient migrations etc. As a result, this review of ancient past of Japan obviously demonstrates that so called isolation of insular population had quiet relative character. During thousands and thousands years, islanders came into contacts with bearers of different cultures of Eurasian mainland and island part of it, as well. The result of these permanent cultural exchanges served as foundation for creation of Japanese ethnos. In certain periods the contacts were more intensive along Northern, or Southern routes; the most significant way went through Korean Peninsula. For Siberian archaeologists the matter of special interest is represented by the finds of early ceramics on Honshu and in East Amur area; by analogies between cultures of Archipelago and Maritime regions of Russia (including Sakhalin and Kuril Islands) in Early Iron Age; by similarities between «Old-kurgans’ culture» at Japan and those in Central Asia. In selection of published materials for this review the preference was given to those available for teachers and students in the universities’ libraries or through free Internet access (published mostly in Russian and English as working languages).
We study a noncommutative generalization of Jordan algebras called Jordan dialgebras. These are algebras that satisfy the identities $[x_1 x_2]x_3= 0$, $(x_1^2,x_2,x_3)=2(x_1,x_2,x_1x_3)$, $x_1(x_1^2 x_2)=x_1^2(x_1 x_2)$; they are related with Jordan algebras in the same way as Leibniz algebras are related to Lie algebras. We present an analogue of the Tits---Kantor---Koecher construction for Jordan dialgebras that provides an embedding of such an algebra into Leibniz algebra.
The article presents the results of a new approach application for oil well galvanic and induction resistivity logs simulation to enhance the efficiency of geological environment parameters evaluation and to speed up the interpretation.

The use of modern machine learning technologies allows us to create algorithms for resistivity logs simulation in high-detailed two-dimensional anisotropic geoelectric models.

The developed algorithms are characterized by a qualitatively new level of performance compared to the approaches used today.
Over the last few years, genome-wide association (GWA) studies became a tool of choice for the identification of loci associated with complex traits. Currently, imputed single nucleotide polymorphisms (SNP) data are frequently used in GWA analyzes. Correct analysis of imputed data calls for the implementation of specific methods which take genotype imputation uncertainty into account.

We developed the ProbABEL software package for the analysis of genome-wide imputed SNP data and quantitative, binary, and time-till-event outcomes under linear, logistic, and Cox proportional hazards models, respectively. For quantitative traits, the package also implements a fast two-step mixed model-based score test for association in samples with differential relationships, facilitating analysis in family-based studies, studies performed in human genetically isolated populations and outbred animal populations.

ProbABEL package provides fast efficient way to analyze imputed data in genome-wide context and will facilitate future identification of complex trait loci.

The article is devoted to the overview of the most popular digital repository support systems and their information model. The choice of DSpace for the data warehouse of the scientific and educational information system is justified.
Raman conversion in multimode GRIN fibers is accompanied by sufficient improvement of the output beam quality in comparison with that for pump radiation, which offers opportunities to create amplifiers and lasers of new type based on directly 9xx-nm diode pumped passive GRIN fibers, which may operate at almost any wavelength in transmission window (0.95-2 micron) of silica fibers. Here we review experimental results and physical mechanisms leading to the beam quality improvement (beam cleaning) in multimode Raman lasers and amplifiers, including effects of Raman gain, fiber Bragg gratings and Rayleigh backscattering feedback in GRIN fibers.
We report the results of a search for the rare, purely leptonic decay B^{-}→μ^{-}ν[over ¯]_{μ} performed with a 711 fb^{-1} data sample that contains 772×10^{6} BB[over ¯] pairs, collected near the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider.

The signal events are selected based on the presence of a high momentum muon and the topology of the rest of the event showing properties of a generic B-meson decay, as well as the missing energy and momentum being consistent with the hypothesis of a neutrino from the signal decay.

We find a 2.4 standard deviation excess above background including systematic uncertainties, which corresponds to a branching fraction of B(B^{-}→μ^{-}ν[over ¯]_{μ})=(6.46±2.22±1.60)×10^{-7} or a frequentist 90% confidence level interval on the B^{-}→μ^{-}ν[over ¯]_{μ} branching fraction of [2.9,10.7]×10^{-7}.
The energy calibration of nuclear recoil detectors is of primary importance to rare-event experiments such as those of direct dark matter search and coherent neutrino-nucleus scattering. In particular, such a calibration is performed by measuring the ionization yield of nuclear recoils in liquid Ar and Xe detection media, using neutron elastic scattering off nuclei. In the present work, the ionization yield for nuclear recoils in liquid Ar has for the first time been measured in the higher energy range, at 80 and 233 keV, using a two-phase Cryogenic Avalanche Detector (CRAD) and DD neutron generator. The ionization yield in liquid Ar at an electric field of 2.3 kV/cm amounted to and at 80 and 233 keV, respectively. The Jaffe model for nuclear recoil-induced ionization, in contrast to that of Thomas-Imel, can probably consistently describe the energy dependence of the ionization yield.
The electronic width of the J / ψ meson and its product by the branching fractions of J / ψ meson decay to hadrons and electrons measured with the KEDR detector at the VEPP-4M e + e − collider have been reported in ref. [1].
