  • Analysis of direct transformation from graphite to diamond crystal 
    Tian, B.; Xu, B.; Xu, Y. (Сверхтвердые материалы, 2016)
    The lattice parameters of cubic diamond and rhombohedral graphite under the probable direct transformation synthesis conditions have been obtained by means of linear expansion coefficient and elastic constant. Based on the ...
  • Discrete Fourier Analysis and Chebyshev Polynomials with G₂ Group 
    Li, H.; Sun, J.; Xu, Y. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    The discrete Fourier analysis on the 30°-60°-90° triangle is deduced from the corresponding results on the regular hexagon by considering functions invariant under the group G₂, which leads to the definition of four families ...
  • Role of turbulence and electric fields in the formation of transport barriers and the establishment of improved confinement in tokamak plasmas through inter-machine comparison 
    Van Oost, G.; Bulanin, V.; Donné, A.J.H.; Gusakov, E.; Krämer-Flecken, A.; Krupnik, L.; Heikkinen, J.; Melnikov, A.; Razumova, K.; Rozhansky, V.; Stöcke, J.; Tendler, M.; Van Schoor, M.; Vershkov, V.; Zajac, J.; Altukov, A.; Andreev, V.; Askinazi, L.; Bondarenko, I.; Dnestrovskij, A.; Eliseev, L.; Esipov, L.; Grashin, S.; Gurchenko, A.; Hogeweij, G.M.D.; Kantor, M.; Kaveeva, E.; Kiviniemi, T.; Khrebtov, S.; Kouprienko, D.; Kurki-Suonio, T.; Lashkul, S.; Lebedev, S.; Leerink, S.; Lysenko, S.; Ogando, F.; Perfilov, S.; Petrov, A.; Popov, A.; Shelukhin, D.; Shurygin, R.; Soldatov, S.; Stepanov, A.; Xu, Y. (Вопросы атомной науки и техники, 2009)
    Over the past decade new regimes of tokamak operation have been identified, whereby electrostatic and magnetic turbulence responsible for anomalous transport, can be externally suppressed, leading to improved confinement. ...
  • S-conditionally permutable subgroups and p-nilpotency of finite groups 
    Xu, Y.; Li, X.H. (Український математичний журнал, 2014)
    We study the p-nilpotency of a group such that every maximal subgroup of its Sylow p-subgroups is s-conditionally permutable for some prime p. By using the classification of finite simple groups, we get interesting new ...
  • Tight Frame with Hahn and Krawtchouk Polynomials of Several Variables 
    Xu, Y. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    Finite tight frames for polynomial subspaces are constructed using monic Hahn polynomials and Krawtchouk polynomials of several variables. Based on these polynomial frames, two methods for constructing tight frames for the ...
