The published data on the preparation and the dispersion-structural properties of nano-sized
TiO 2 are considered. Attention is focused on its sol–gel synthesis from different precursors. …

Almost bent functions oppose an optimum resistance to linear and differential cryptanalysis.
We present basic properties of almost bent functions; particularly we give an upper bound …

… of the improvements on the Levenshtein bound, to Danyo Danev for helping with computations
of bounds and for careful reading of several parts of the manuscript, to Dmitrii Zinoviev for …

The experiment Neutrino-4 started in 2014 with a detector model and continued with a full-scale
detector in 2016–2021. In this article, we describe all the steps of the preparatory work …

We report Neutrino-4 experiment results of measurements of reactor antineutrinos flux and
spectrum dependence on the distance in range 6–12 m from the center of the reactor core. …

Several constructions are presented by which spherical codes are generated from groups of
binary codes. In the main family of constructions the codes are generated from equally …

Studying the coset weight distributions of the Z 4 -linear Goethals codes, e connect these
codes with the Kloosterman sums. From one side, e obtain for some cases, of the cosets of …

Polynomials of type x q + 2 + b x over the field F q 2 and of type x q 2 + q + 2 + b x over F q 3
, where q = p m > 2 is a power of a prime p are considered. All cases when these …

This work is devoted to the study of the sorption characteristics of various hollow
microspherical membranes to reveal particles most suitable for application in the membrane-sorption …

Experiments were performed to investigate the effects of grain size (2–1100 μm) and temperature
(77–1023 K) on the strength, hardness and ductility of stoichiometric Ni 3 Al with (0.35 …
