Research of X-ray induced conductivity of ZnSe sensors for their application in isotopic thickness gaugesJun 11 2011Measurements of intrinsic conductivity and X-ray induced conductivity were performed on specially undopped ZnSe samples. The measurements demonstrated that sensors made of ZnSe have minor intrinsic conductivity when heating up to the temperature of 180 ... More

On the hidden symmetries of relativistic hydrogen atomJun 14 2019The Dirac equation in the external Coulomb field is proved to possess the symmetry determined by the 31 operators, which form the 31-dimensional algebra. Two different fermionic realizations of the SO(1,3) algebra of the Lorentz group are found. Two different ... More

Covariant local field theory equations following from the relativistic canonical quantum mechanics of arbitrary spinAug 22 2014Sep 19 2014The new relativistic equations of motion for the particles with spin s=1, s=3/2, s=2 and nonzero mass have been introduced. The description of the relativistic canonical quantum mechanics of the arbitrary mass and spin has been given. The link between ... More

Quantum Lie algebras of type A_nOct 03 1995Dec 07 1995It is shown that the quantised enveloping algebra of sl(n) contains a quantum Lie algebra, defined by means of axioms similar to Woronowicz's., This gives rise to Lie algebra-like generators and relations for the locally finite part of the quantised enveloping ...

Effect of traps on the current impulse from X-ray induced conductivity in wide-gap semiconductorsDec 10 2014This article presents a theoretical model for the calculation of the current impulse from X-ray induced conductivity in wide-gap semiconductors that contain different types of traps and recombination centres. The absorption of one X-ray photon in a semiconductor ... More

Kinetics of Charge Transport in Wide-Band Semiconductors at the Detection of X-Ray RadiationJan 28 2011As a result of absorption of X-ray quantum in a semiconductor, the generation of electron-hole pairs takes place in a small volume (diameter < 0.5 mkm). Their surplus energy is lost due to the scattering on phonons of the crystal lattice. Spatial distribution ... More

Likelihood-free MCMC with Approximate Likelihood RatiosMar 10 2019We propose a novel approach for posterior sampling with intractable likelihoods. This is an increasingly important problem in scientific applications where models are implemented as sophisticated computer simulations. As a result, tractable densities ... More

Simulating Data Access Profiles of Computational Jobs in Data GridsFeb 26 2019The data access patterns of applications running in computing grids are changing due to the recent proliferation of high speed local and wide area networks. The data-intensive jobs are no longer strictly required to run at the computing sites, where the ... More
