Abstract
The RED-100 experiment with a liquid xenon target was
carried out at Kalinin Nuclear Power Plant. The goal of the
experiment is the detection and study of the coherent elastic
neutrino ...nucleus scattering process (CEνNS) for the low-energy
antineutrinos in close vicinity to a reactor core. A good
understanding of the external radioactive background is needed to
achieve this goal. This paper describes the external background
conditions for the RED-100 experiment at Kalinin Nuclear Power
Plant.
The role of the nuclear protein coilin in the mechanisms of resistance of potato
Solanum tuberosum
cultivar Chicago to biotic and abiotic stresses was studied using the CRISPR–Cas9 technology. For ...the coilin gene editing, a complex consisting of the Cas9 endonuclease and a short guide RNA was immobilized on gold or chitosan microparticles and delivered into apical meristem cells by bioballistics or vacuum infiltration methods, respectively. Editing at least one allele of the coilin gene considerably increased the resistance of the edited lines to infection with the potato virus Y and their tolerance to salt and osmotic stress.
The subject of the research is social relations that arise in the course of the activities of voluntary squads during martial law, including the possibility of their involvement by law enforcement ...and other bodies in the performance of state tasks to ensure public order and national security. The purpose of the work is to determine the theoretical and applied problems of legal regulation of the administrativelegal status of a voluntary squad during the period of martial law. When writing the article, formal-legal, historical-and comparative-legal, logical methods were used. The relevance of the topic is associated with the lack of a clear and even mechanism for the creation and functioning of voluntary squads precisely during the period of martial law. At the legislative level, their competence (powers, forms and acts of responding to violations of laws by individuals and legal entities) in the process of ensuring public order in the controlled territory is not defined. The fact of the absence of a single terminological series in the formation of the legal basis for the activities of voluntary squads is stated. The main part of the article substantiates the conclusion that such voluntary public organizations, taking into account their basic characteristics, should be referred to in regulatory legal acts, regardless of the direction of their action, as a “voluntary people's squad”. A comparative analysis of the legal status of a voluntary squad and volunteer formations is presented. It is concluded that they do not correlate as general and private, voluntary formation, due to the specifics of the goals of education, functioning and financing, is not a kind of voluntary squads. The conclusion is substantiated that voluntary squads should be actively used by law enforcement agencies to ensure the strengthening of public order during martial law. The question is raised about the need to specify in the normative legal acts the administrative and legal status of voluntary squads precisely in the period of martial law. Proposals are made on the mechanism of legal regulation of the powers of voluntary teams and the social and legal protection of combatants when they perform state tasks under these conditions.

Abstract
The RED-100 two-phase xenon emission detector has been
deployed at 19-m distance from the reactor core of the Kalinin
Nuclear Power Plant (KNPP) in 2021–2022 for investigation of the
...possibility to observe reactor antineutrinos using the effect of
coherent elastic neutrino-nucleus scattering (CE
ν
NS). The
performance of the main systems of the RED-100 setup at operating
nuclear power plant is described. There is no correlation of the
radioactive background at the experimental setup site with ON and
OFF states of the reactor. The data taking run was carried out at
the beginning of the year 2022 and covered both the reactor OFF and
ON periods.

A combined passive shield of the RED-100 two-phase emission neutrino detector has been developed and built for suppressing the background of external γ rays and neutrons. The shield is composed of ...a 5‑cm-thick copper layer (the inner layer is adjacent to the detector) and a water layer with a total thickness of approximately 70 cm (including the water inside the copper shield). The Monte Carlo simulation of the shielding efficiency has been performed. The obtained attenuation factor of the copper shield for the γ-ray background has been experimentally verified in a laboratory test using a NaI(Tl) scintillator detector. The γ‑ray background rejection factor of the full shield has also been calculated.

The review presents the results of the blood substitute development based on perfluororganic compounds (PFC). The limitations of PFC due to which their further development was suspended are ...described. The presented data allows us to imagine a possible way to create optimal drugs based on PFC. Chemically inactive perfluorocomponents should be used — perfluorinated hydrocarbons and tertiary perfluorinated amines. However, in order to emulsify and stabilize the emulsion, other types of effective and chemically indifferent surfactants that do not interact with oxygen and other components of the drug are needed.
We present recent results on the first experimental observation of the coherent elastic scattering of the neutrino on atomic nuclei and review other experiments related to the detection and ...investigation of this process.

It is shown that the working volume of the RED-100 two-phase emission detector, which operates in a ground-based laboratory with liquid xenon used as a working substance, is a source of ...single-electron noise signals with a characteristic frequency of ~200 kHz. Possible mechanisms of generation of these noises and methods for their suppression are discussed.
A cycle of experimental investigations is carried out, specifically, the measurements and analysis of field dependences of the static magnetic susceptibility in samples of single-crystal SiC thin ...films grown on the (100), (110), and (111) surfaces of a Si single crystal by the method of the self-consistent substitution of atoms due to the chemical reaction of silicon with carbon-monoxide (CO) gas. As a result of investigations in SiC structures grown on Si(110) and Si(111), the appearance of two quantum effects is found in weak magnetic fields at room temperature. These effects are, first, the formation of hysteresis of the static magnetic susceptibility and, second, the generation of Aharonov–Bohm oscillations in the field dependences of the static magnetic susceptibility. The first effect is associated with the Meissner–Ochsenfeld effect and the second effect, with the presence of microdefects in the form of nanotubes and micropores formed during the synthesis of structures in them under the SiC layer. In the SiC structures grown on Si(100), these effects are not detected, which is related to a different mechanism of SiC formation on the Si(100) surface.
