  • Majewski, M.Ł. (Історичний архів. Наукові студії, 2015)
    Po podpisaniu w 1921 roku traktatu pokojowego w Rydze, na terenie Polski znalazło się 20 tysięcy ukraińskich żołnierzy atamana Petlury. Ukraińscy żołnierze zostali umieszczeni w obozach na terytorium całego kraju. Jednym ...
  • Mazhaev, A. (Наука та інновації, 2017)
    Ukraine Virtual Observatory (UkrVO) has been a member of the International Virtual Observatory Alliance (IVOA) since 2011. The virtual observatory (VO) is not a magic solution to all problems of data storing and processing, ...
  • Schekotov, A.; Fedorov, E.; Hobara, Y.; Hayakawa, M. (Радіофізика та електроніка, 2013)
    The depression (reduction in amplitude) of ULF magnetic field variations of magnetospheric origin is studied at various distances from the epicenter of the strongest earthquake (EQ), which occurred in Japan on March 11, ...
  • Pavlenko, Ya.V. (Кинематика и физика небесных тел, 2005)
    We present results of modelling of spectra of M-, L-, T-dwarfs. Theoretical spectra are fitted to observed spectra to study the main parameters of the low-mass objects beyond the bottom of the Main Sequence. Application ...
  • Takemura, K.; Tsutsui, T. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    We introduce a ultradiscretization with parity variables of the q-difference Painlevé VI system of equations. We show that ultradiscrete limit of Riccati-type solutions of q-Painlevé VI satisfies the ultradiscrete Painlevé ...
  • Kondo, K. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    Ultradiscretization with negative values is a long-standing problem and several attempts have been made to solve it. Among others, we focus on the symmetrized max-plus algebra, with which we ultradiscretize the discrete ...
  • Kirilyuk, A.; Kimel, A.; Pisarev, R.V.; Hansteen, F.; Rasing, T. (Физика низких температур, 2006)
    The purpose of this review is to summarize the recent progress on laser-induced magnetization dynamics in magnetic dielectrics. Due to the slow phonon–magnon interaction in these materials, direct thermal effects of the ...
  • Ignatyuk, V.V.; Morozov, V.G. (Condensed Matter Physics, 2004)
    Non-Markovian kinetic equations in the second Born approximation are derived for a two-zone semiconductor excited by a short laser pulse. Both collision dynamics and running nonequilibrium correlations are taken ...
  • Korovin, A.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2012)
    The ultrafast interaction between high power laser light and plasma has been studied theoretically. The theoretical simulations are based on the nonlinear Schrödinger equation taking into account group velocity dispersion, ...
  • Protasov, I.V.; Slobodianiuk, S.V. (Український математичний журнал, 2015)
    A ballean (equivalently, a coarse structure) is an asymptotic counterpart of a uniform space. We introduce three ultrafilter satellites of a ballean (namely, corona, companion, and corona companion), evaluate the basic ...
  • Petrenko, O.V.; Protasov, I.V. (Algebra and Discrete Mathematics, 2015)
    For a discrete group G and a discrete G-space X, we identify the Stone-Cech compactifications βG and βX with the sets of all ultrafilters on G and X, and apply the natural action of βG on βX to characterize large, thick, ...
  • Vitusevich, S.A.; Danylyuk, S.V.; Danilchenko, B.A.; Klein, N.; Zelenskyi, S.E.; Drok, E.; Avksentyev, A.Yu.; Sokolov, V.N.; Kochelap, V.A.; Belyaev, A.E.; Petrychuk, M.V.; Luth, H. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2006)
    This paper describes measurements of the velocity of electrons at electric fields up to 100 kV/cm in GaN/AlGaN heterostructures. In order to avoid the Joule heating effect, a pulse technique with a time sweep of 10-30 ns ...
  • Strzyzewski, P.; Langner, J.; Sadowski, M.J.; Witkowski, J.; Sekutowicz, J. (Вопросы атомной науки и техники, 2007)
    The paper presents recent experimental studies aimed at the deposition of superconducting films of pure lead (Pb) by means of the UHV cathodic arc. Such layers can be used as photo-cathodes needed for modern accelerator ...

  • Goponov, Yu.A.; Sidnin, M.A.; Sumitani, K.; Takabayashi, Y.; Vnukov, I.E. (Вопросы атомной науки и техники, 2015)
    The use of ultra relativistic electron (positron) emission in thin crystals to estimate particle beam spatial sizes for projected electron-positron colliders is proposed. The existing position-sensitive X-ray range detectors ...
  • Balakirev, V.A.; Onishchenko, I.N.; Sidorenko, D.Yu.; Sotnikov, G.V. (Радиофизика и радиоастрономия, 2002)
    The theoretical investigations and simulation are performed for the emission of a relativistic electron bunch during the injection into a semi-infinite vacuum/dielectric waveguide. The exact solution of the problem is ...
