Cybersecurity Development Problems in Ukraine
To date, the problem of cybersecurity is topical. Every day, each of us is faced
with the need to use information technology, beginning with the placement of
personal information on the Internet, to the use of ATMs, bank accounts, etc. Hence
the question arises whether this problem is controlled by national legislation and
whether our information is well protected
A new method for the experimental study of topological effects in the quark-gluon plasma
A new method is presented for the quantitative measurement of charge
separation about the reaction plane. A correlation function is obtained whose
shape is concave when there is a net separation of positive and negative
charges. Correlations not specifically associated with charge, from flow, jets
and momentum conservation, do not influence the shape or magnitude of the
correlation function. Detailed simulations are used to demonstrate the
effectiveness of the method for the quantitative measurement of charge
separation. Such measurements are a pre-requisite to the investigation of
topological charge effects in the QGP as derived from the "strong
problem".Comment: Six pages 13 figures. Submitted for publicatio
Glauber-based evaluations of the odd moments of the initial eccentricity relative to the even order participant planes
Monte Carlo simulations are used to compute the centrality dependence of the
odd moments of the initial eccentricity , relative to the even
order (n) participant planes in Au+Au collisions. The results
obtained for two models of the eccentricity -- the Glauber and the factorized
Kharzeev-Levin-Nardi (fKLN) models -- indicate magnitudes which are essentially
zero. They suggest that a possible correlation between the orientations of the
the odd and even participant planes ( and
respectively), do not have a significant influence on the calculated
eccentricities. An experimental verification test for correlations between the
orientations of the the odd and even participant planes is also proposed.Comment: 3 pages, 1 figure. Version accepted for publicatio
