Scientific and methodological support for socialization of teenage mothers in the specialized agencies

The paper deals with the issues that arise in solving problems of socialization of teenage mothers. The article is based on an analysis of the activities of the specialized agencies, in which minor expectant mothers from fourteen years, and teenage mothers with children under the age of one year (as an exception - up to three years) can live. Problems associated with the socialization of teenage mothers, are due to the internal and external factors on the activities of the institution. In addition, most pupils personalities do not fit the conventional patterns. In the period when the pupils live in their learning institutions, they are provided with life skills in modern conditions, formation of their abilities and skills for life, child-rearing, recreation, family budgeting, etc. Socialization of pupils considering their situations is focused on their social adaptation, increase of their socially active position, facilitating their professional orientation and obtaining a profession. All this requires a strengthening of the scientific and methodical work. Consequently, it is necessary to study the scientific and methodical directions and content of interaction with the social institutions of Moscow in order to realize their potential in solving the problems of socialization of pupils, effective use of social and cultural institutions, institutions of general and vocational education

Coherent information analysis of quantum channels in simple quantum systems

The coherent information concept is used to analyze a variety of simple quantum systems. Coherent information was calculated for the information decay in a two-level atom in the presence of an external resonant field, for the information exchange between two coupled two-level atoms, and for the information transfer from a two-level atom to another atom and to a photon field. The coherent information is shown to be equal to zero for all full-measurement procedures, but it completely retains its original value for quantum duplication. Transmission of information from one open subsystem to another one in the entire closed system is analyzed to learn quantum information about the forbidden atomic transition via a dipole active transition of the same atom. It is argued that coherent information can be used effectively to quantify the information channels in physical systems where quantum coherence plays an important role.Comment: 24 pages, 7 figs; Final versiob after minor changes, title changed; to be published in Phys.

Elliptic flow of charged particles at midrapidity relative to the spectator plane in Pb–Pb and Xe–Xe collisions

Measurements of the elliptic flow coefficient relative to the collision plane defined by the spectator neutrons v2{ SP} in collisions of Pb ions at center-of-mass energy per nucleon–nucleon pair √ 2.76 TeV and Xe ions at √ sNN = sNN =5.44 TeV are reported. The results are presented for charged particles produced at midrapidity as a function of centrality and transverse momentum for the 5–70% and 0.2–6 GeV/c ranges, respectively. The ratio between v2{ SP} and the elliptic flow coefficient relative to the participant plane v2{4}, estimated using four-particle correlations, deviates by up to 20% from unity depending on centrality. This observation differs strongly from the magnitude of the corresponding eccentricity ratios predicted by the TRENTo and the elliptic power models of initial state fluctuations that are tuned to describe the participant plane anisotropies. The differences can be interpreted as a decorrelation of the neutron spectator plane and the reaction plane because of fragmentation of the remnants from the colliding nuclei, which points to an incompleteness of current models describing the initial state fluctuations. A significant transverse momentum dependence of the ratio v2{ SP}/v2{4} is observed in all but the most central collisions, which may help to understand whether momentum anisotropies at low and intermediate transverse momentum have a common origin in initial state f luctuations. The ratios of v2{ SP} and v2{4} to the corresponding initial state eccentricities for Xe–Xe and Pb–Pb collisions at similar initial entropy density show a difference of (7.0 ±0.9)%with an additional variation of +1.8% when including RHIC data in the TRENTo parameter extraction. These observations provide new experimental constraints for viscous effects in the hydrodynamic modeling of the expanding quark–gluon plasma produced in heavy-ion collisions at the LHC

First measurement of Ωc0 production in pp collisions at s=13 TeV

The inclusive production of the charm–strange baryon 0 c is measured for the first time via its hadronic √ decay into −π+ at midrapidity (|y| <0.5) in proton–proton (pp) collisions at the centre-of-mass energy s =13 TeV with the ALICE detector at the LHC. The transverse momentum (pT) differential cross section multiplied by the branching ratio is presented in the interval 2 < pT < 12 GeV/c. The pT dependence of the 0 c-baryon production relative to the prompt D0-meson and to the prompt 0 c-baryon production is compared to various models that take different hadronisation mechanisms into consideration. In the measured pT interval, the ratio of the pT-integrated cross sections of 0 c and prompt + c baryons multiplied by the −π+ branching ratio is found to be larger by a factor of about 20 with a significance of about 4σ when compared to e+e− collisions

Detection of the PRAME Protein on the Surface of Melanoma Cells Using a Fluorescently Labeled Monoclonal Antibody

Abstract: Determination of the expression level of tumor marker PRAME protein is important both for predicting the course of the disease and for monitoring the effectiveness of anticancer therapy. A fluorescently labeled monoclonal antibody to the PRAME protein was obtained by periodate oxidation of glycans followed by modification with a bifunctional azido-oxyamine reagent and a “click” reaction with alkyne-modified sulfonated cyanine dye Cy3. A new approach to the synthesis of a bifunctional azido-oxyamine reagent using the ethoxyethylidene protecting group for oxyamine is proposed. The labeled antibodies were characterized with UV/Vis absorption spectra and the stoichiometry of the modification was determined. It has been demonstrated that the fluorescent antibodies retain affinity and can be used as a diagnostic tool for detecting the residual marker (the PRAME protein) after anticancer therapy. © 2021, Pleiades Publishing, Ltd
