  • Limits of applicability of the weakly relativistic approximation in the theory of plasma waves 
    Pavlov, S.S.; Castejón, F. (Вопросы атомной науки и техники, 2018)
    The more general weakly-relativistic plasma dispersion functions are introduced and discussed in the frame of the fully relativistic approach for the theory of plasma waves.
  • Limits of Gaudin Systems: Classical and Quantum Cases 
    Chervov, A.; Falqui, G.; Rybnikov, L. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    We consider the XXX homogeneous Gaudin system with N sites, both in classical and the quantum case. In particular we show that a suitable limiting procedure for letting the poles of its Lax matrix collide can be used to ...
  • Limits on the real line of symmetric spaces on segments 
    Kucher, О.V.; Plichko, A.M. (Український математичний журнал, 1995)
    In the same way as the known spacesM p ,M p , andI p are constructed on the basis of the spaceL p (−1, 1), we construct the corresponding “limit” spacesM E ,M E , andI E on the real line on the basis of a symmetric function ...
  • The limit stochastic equation changes type 
    Makhno, S.Ya. (2005)
    We study the weak convergence of solutions of the Itˆo stochastic equation, whose coeffcients depend on a small parameter. Conditions under which the limit process changes the type and will be a solution of the stochastic ...

    Bondarenko, A. (2007)
    A limit theorem for the strongly regular semi-Markov process is proved under conditions C1 – C3.
  • A limit theorem for symmetric Markovian random evolution in R^m 
    Kolesnik, A.D. (2008)
    We consider the symmetric Markovian random evolution X(t) performed by a particle that moves with constant finite speed c in the Euclidean space R^m, m >= 2. Its motion is subject to the control of a homogeneous Poisson ...
  • A limit theorem for the number of sign changes for a sequence of one-dimensional diffusions 
    Kulik, A.M. (2008)
    The (normalized) number of sign changes for a weakly convergent sequence of onedimensional diffusion processes is considered. The limit theorem for this number is established.
  • Limit theorems for backward stochastic equations 
    Makhno, S.Ya.; Yerisova, I.A. (2008)
  • Limit theorems for oscillatory functionals of a Markov process 
    Androshchuk, T.O.; Kulik, A.M. (2005)
    We study the limit behavior of a family of functionals from a given Markov process which are called oscillatory functionals. The typical oscillatory functional is homogeneneous and non-negative but neither additive nor ...
  • Limnoricus ponticus sp. n. — новый вид щупальцевых инфузорий (Ciliophora, Suctorea) с гарпактикоид рода Tisbe 
    Довгаль, И.В.; Лозовский В.Л. (Вестник зоологии, 2008)
    Приведено описание нового вида сукторий-парацинетид Limnoricus ponticus Dovgal et Lozowskiy, sp. n. От других видов рода (L. ceter и L. seticolus) новый вид отличается наличием длинного, складчатого стеблевидного выроста ...
  • Limnothrix redeckei (Van Goor) Meffert (Cyanoprokaryota) в планктоне р. Барнаулки (Россия) 
    Романов, Р.Е. (Альгология, 2007)
    В результаті досліджень в кінці літа – на початку осені 2002-2003 рр. в планктоні нижньої течії рівнинної р. Барнаулки з незарегульованим стоком виявлено значний розвиток лімнофільного Limnothrix redeckei (Van Goor) Meffert, ...
  • Linac failure diagnostics 
    Akchurin, Yu.I.; Boriskin, V.N.; Ivahnenko, M.V.; Levandovsky, S.P.; Orlova, E.I.; Savchenko, A.N. (Вопросы атомной науки и техники, 1999)
    The data processing subroutine from 60 discrete detectors is developed for the operating control system [1] of the technological linac. It uses a dialogue regime of work. This subroutine allows us to find a basic cause of ...
  • Linear accelerators for radiation sterilization developed in NPK LUTS NIIEFA 
    Vorogushin, M.F.; Gavrish, Yu.N.; Demsky, M.I.; Maksimov, V.M. (Вопросы атомной науки и техники, 2004)
    NPK LUTS NIIEFA has been developing linear accelerators for industrial applications during about 30 years. More than 150 linear accelerators for different applications have been manufactured by this company and installed in ...
  • Linear and Nonlinear EEG Synchronization in Alzheimer’s Disease 
    Vyšata, O.; Vališ, M.; Procházka, A.; Rusina, R.; Pazdera, L. (Нейрофизиология, 2015)
    As is known, Alzheimer’s disease (AD) is associated with cognitive deficits due to significant neuronal loss. Reduced connectivity might be manifested as changes in the synchronization of electrical activity of collaborating ...
  • Linear and nonlinear instability of flow in channel occupied porous media 
    Avramenko, A.A.; Dmitrenko, N.P.; Kovetskaya, Y.Y. (Промышленная теплотехника, 2017)

    Slutskii, M.I. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2004)
    The electrical field dependencies of current I and its variation under phonon pulses - ΔIph, were measured in δ-doped GaAs with n = 5*10¹¹ nm⁻². It was shown that if E< 1 V/cm and T = 2 K, E/I, and E/Iph linearly increase ...
