Legal Liability for the Violation of Traffic Rules by a Person Subjected to an Administrative Penalty

In the article actual problems of qualification of repeated driving of a car, a tram or other mechanical vehicle by a person in the state of intoxication are considered (Article 264.1 of the Criminal Code of the Russian Federation). Ways to solve these problems are suggested. The problems of establishing administrative prejudice in criminal legislation are identified, taking into account the provisions of the decision of the Constitutional Court of the Russian Federation of February 10, 2017 no. 2-P. The problems of qualification of repeated driving of a vehicle by a person in the state of intoxication are investigated. It is substantiated that Art. 264.1 of the Criminal Code of the Russian Federation is a norm with double prevention. The conclusion is made that it is necessary to adopt a resolution of the Plenum of the Supreme Court of the Russian Federation where an interpretation will be given of the application of norms with administrative prejudice to develop a unified approach to understanding the criminalization of such acts and the grounds for prosecuting those who committed them

Formation of high-carbon abrasion-resistant surface layers when high-energy heating by high-frequency currents

The paper shows the possibility of carburization of low-carbon steel surface layers using high-frequency currents. The mathematical modeling of carburization using high-energy heating by high-frequency currents (HEH HFC) has been carried out, the temperature fields formed during the given processing have been calculated, as well as the structural changes in the surface layers have been simulated. The features of the structure formation in the surface layers of low-carbon steel after carburizing via HEH HFC have been determined by optical and scanning microscopy, which is confirmed by the computational models. The rational mode of fusion via HEH HFC has also been determined (power density of the source q[s]=(1.5...4.0)•10{8} W m{-2}, (the relative travel speed of parts V[p]=5 ... 100 mm /sec), with forming the compressive retained stresses in the surface layer ([sigma][RS]=-300...-400 MPa)

Crossreactive T Cells Spotlight the Germline Rules for αβ T Cell-Receptor Interactions with MHC Molecules

SummaryTo test whether highly crossreactive αβ T cell receptors (TCRs) produced during limited negative selection best illustrate evolutionarily conserved interactions between TCR and major histocompatibility complex (MHC) molecules, we solved the structures of three TCRs bound to the same MHC II peptide (IAb-3K). The TCRs had similar affinities for IAb-3K but varied from noncrossreactive to extremely crossreactive with other peptides and MHCs. Crossreactivity correlated with a shrinking, increasingly hydrophobic TCR-ligand interface, involving fewer TCR amino acids. A few CDR1 and CDR2 amino acids dominated the most crossreactive TCR interface with MHC, including Vβ8 48Y and 54E and Vα4 29Y, arranged to impose the familiar diagonal orientation of TCR on MHC. These interactions contribute to MHC binding by other TCRs using related V regions, but not usually so dominantly. These data show that crossreactive TCRs can spotlight the evolutionarily conserved features of TCR-MHC interactions and that these interactions impose the diagonal docking of TCRs on MHC

The article gives an estimation and a calculation of the reliability indexes for the downhole telemetry system downhole unit under severe operating conditions of high temperature environment. The reliability-growth methods are suggested. It is shown that the use of redundancy significantly extends mean time to failure even in high temperature environment. © 2017 Author(s).Work on PNIER RFMEFI57815X0134 was performed with the financial support of the Ministry of Education and Science of the Russian Federation as a part of the agreement No. 14.578.21.0134 on 27 October 2015

Steady state of atoms in a resonant field with elliptical polarization

We present a complete set of analytical and invariant expressions for the steady-state density matrix of atoms in a resonant radiation field with arbitrary intensity and polarization. The field drives the closed dipole transition with arbitrary values of the angular momenta $J_{g}$ and $J_{e}$ of the ground and excited state. The steady-state density matrix is expressed in terms of spherical harmonics of a complex direction given by the field polarization vector. The generalization to the case of broad-band radiation is given. We indicate various applications of these results.Comment: revtex, 26 pages, including 3 eps figures; PRA accepted for publication;v2 three typos are fixe

РЕОРГАНИЗАЦИЯ МЕЖКЛЕТОЧНЫХ АДГЕЗИОННЫХ КОНТАКТОВ И ПОЯВЛЕНИЕ МИГРАЦИОННОЙ АКТИВНОСТИ У КЛЕТОК MCF-7-SNAI1 ПРИ ИНДУКЦИИ ЭПИТЕЛИАЛЬНО-МЕЗЕНХИМАЛЬНОГО ПЕРЕХОДА

Using DIC and confocal microscopy, changes in morphology, migratory characteristics and adherence junctions (AJs) were analyzed in the mammary carcinoma cell line MCF-7-SNAI1  after activation of the EMT transcription factor SNAI1. Western Blot analysis showed that  after removal of tetracycline from the cell culture medium expression of SNAI1 reached its  peak in 24 hours and then plateaued for 7 days. During the 7 days the cells continued to  express E-cadherin; however, tangential AJs typical for cells with stable cell-cell adhesion,  changed into radial AJs. The radial AJs continued to accumulate E-cadherin during 24‑72  hours after tetracycline removal. As a result of SNAI1 activation, the cells underwent  epithelial-mesenchymal transition (EMT) and became migratory. On a two-dimensional  substrate, cells exhibited both individual and collective migration. As the tetracycline  washout period progressed, the fraction of the cells capable of migrating through migration chamber membranes increased; on the contrary, cells’ ability to invade an epithelial  monolayer decreased. These results demonstrate that retaining a hybrid epithelial/mesenchymal  phenotype and accumulation of E-cadherin in AJs during early stages of EMT do not impede  disruption of stable cell-cell adhesion and cells’ acquisition of migratory activity.С помощью DIC-микроскопии и конфокальной микроскопии были проанализированы изменения морфологии,  миграционных характеристик и межклеточных адгезионных контактов в культуре клеток рака молочной железы MCF-7-SNAI1 при активации экспрессии транскрипционного фактора ЭМП – SNAI1. Как показал Вестерн-блот  анализ, экспрессия SNAI1 достигала максимальных значений через 24 часа после переноса клеток в среду без  тетрациклина и поддерживалась на этом уровне в течение семи дней. В клетках в течение семи дней  сохранялась экспрессия Е-кадхерина, при этом тангенциальные межклеточные адгезионные контакты,  характерные для клеток со стабильной межклеточной адгезией, замещались радиальными контактами. В  радиальных контактах в течение 24–72 часов отмывки от тетрациклина продолжалась аккумуляция Е- кадхерина. В результате активации SNAI1 клетки вступали в ЭМП и приобретали миграционную активность. На  двумерном субстрате клетки мигрировали как индивидуально, так и коллективно. С увеличением  продолжительности отмывки от тетрациклина повышался процент клеток, мигрировавших через поры в  миграционных камерах, способность клеток инвазировать эпителиальный монослой, напротив, снижалась.  Полученные данные свидетельствуют о том, что сохранение гибридного эпителиально-мезенхимального  фенотипа и аккумуляция Е-кадхерина в межклеточных адгезионных контактах на ранних этапах ЭМП не  препятствуют разрушению стабильной межклеточной адгезии и приобретению клетками миграционной активности
