The learners' electronic portfolio system (E-Portfolio) as an element of the information enviroment for managing the educational process

This article is devoted to the methodological and practical approaches to developing and implementing the electronic portfolios for learners as part of the electronic educational environment for managing the learning process. Based on the modern model of education in the pedagogical university, as well as on the federal state standard, the main sections of the system of the students' electronic portfolio have been formulated, which describe the main educational, scientific and other achievements of the students. In addition, the functional capabilities of the software implementation of an example of the electronic portfolio, software architecture and the methodological approaches to working with the system have been substantiated. The application of the students' electronic portfolios allows us to quickly obtain the information about the status of the main parameters of student activities and to stimulate them in different areas of the activities

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
