Tunka Advanced Instrument for cosmic rays and Gamma Astronomy
The paper is a script of a lecture given at the ISAPP-Baikal summer school in
2018. The lecture gives an overview of the Tunka Advanced Instrument for cosmic
rays and Gamma Astronomy (TAIGA) facility including historical introduction,
description of existing and future setups, and outreach and open data
activities.Comment: Lectures given at the ISAPP-Baikal Summer School 2018: Exploring the

Measurement of the Pion Form Factor in the Energy Range 1.04-1.38 GeV with the CMD-2 Detector
The cross section for the process is measured in the
c.m. energy range 1.04-1.38 GeV from 995 000 selected collinear events
including 860000 events, 82000 events, and 33000
events. The systematic and statistical errors of measuring the
pion form factor are equal to 1.2-4.2 and 5-13%, respectively.Comment: 5 pages, 2 figure
The FLASHForward Facility at DESY
The FLASHForward project at DESY is a pioneering plasma-wakefield
acceleration experiment that aims to produce, in a few centimetres of ionised
hydrogen, beams with energy of order GeV that are of quality sufficient to be
used in a free-electron laser. The plasma wave will be driven by high-current
density electron beams from the FLASH linear accelerator and will explore both
external and internal witness-beam injection techniques. The plasma is created
by ionising a gas in a gas cell with a multi-TW laser system, which can also be
used to provide optical diagnostics of the plasma and electron beams due to the
<30 fs synchronisation between the laser and the driving electron beam. The
operation parameters of the experiment are discussed, as well as the scientific
program.Comment: 19 pages, 9 figure
Formation of a digital educational environment in the practical classes at the Department of Histology (On example of the Ural State Medical University)
The article provides the experience of the Department of Histology of the Ural State Medical University (USMU) in creating a digital educational environment in practical histology classes. Most of the class time is devoted to work using individual microscopes and sets of histological preparations. Students consider it correct and quite effective to use full‑slide images of micropreparations as an additional educational resource in the study. A promising area of work on the digitalization of the educational process at the Department of Histologyof the USMU is the placement of developed digital educational products (gallery, atlas of full‑slide images of micropreparations) and methodological support for them in the public domain on the USMU server.В статье обобщен опыт работы кафедры гистологии Уральского государственного медицинского университета (УГМУ) по созданию цифровой образовательной среды в рамках практических занятий, определены факторы, ускорившие цифровизацию. Большая часть времени занятий отводится на работу с использованием индивидуальных микроскопов и наборов гистологических препаратов. Студенты считают правильным и достаточно эффективным применение оцифрованных микропрепаратов в качестве дополнительного обучающего ресурса при изучении микропрепаратов. Перспективным направлением работы по цифровизации образовательного процесса на кафедре гистологии УГМУ является размещение разработанных цифровых образовательных продуктов (галереи, атласа полнослайдовых изображений микропрепаратов) и методического сопровождения к ним в открытом доступе на сервере УГМУ
Nuclear Polarization of Molecular Hydrogen Recombined on a Non-metallic Surface
The nuclear polarization of molecules formed by recombination
of nuclear polarized H atoms on the surface of a storage cell initially coated
with a silicon-based polymer has been measured by using the longitudinal
double-spin asymmetry in deep-inelastic positron-proton scattering. The
molecules are found to have a substantial nuclear polarization, which is
evidence that initially polarized atoms retain their nuclear polarization when
absorbed on this type of surfac
