  • B2B Exchanges — opportunity for Purchasing Process 
    Kot, S. (Электронное моделирование, 2007)
    The paper presents background of B2B exchanges and review of their forms and functionalities. The rapid growth of B2B trade revenues and their details are noticed. European and Polish interest in B2B trade is next aspect ...
  • Bäcklund-Darboux Transformation for Non-Isospectral Canonical System and Riemann-Hilbert Problem 
    Sakhnovich, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    A GBDT version of the Bäcklund-Darboux transformation is constructed for a non-isospectral canonical system, which plays essential role in the theory of random matrix models. The corresponding Riemann-Hilbert problem is ...
  • Bäcklund-Darboux Transformations and Discretizations of Super KdV Equation 
    Xue, L.L.; Liu, Q.P. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    For a generalized super KdV equation, three Darboux transformations and the corresponding Bäcklund transformations are constructed. The compatibility of these Darboux transformations leads to three discrete systems and ...
  • Bäcklund Transformation for the BC-Type Toda Lattice 
    Kuznetsov, V.; Sklyanin, E. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    We study an integrable case of n-particle Toda lattice: open chain with boundary terms containing 4 parameters. For this model we construct a Bäcklund transformation and prove its basic properties: canonicity, commutativity ...

    Carillo, S.; Lo Schiavo, M.; Schiebold, C. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    Classes of third order non-Abelian evolution equations linked to that of Korteweg-de Vries-type are investigated and their connections represented in a non-commutative Bäcklund chart, generalizing results in [Fuchssteiner ...
  • Bäcklund Transformations for First and Second Painlevé Hierarchies 
    Sakka, A.H. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    We give Bäcklund transformations for first and second Painlevé hierarchies. These Bäcklund transformations are generalization of known Bäcklund transformations of the first and second Painlevé equations and they relate the ...
  • Bäcklund Transformations for the Kirchhoff Top 
    Ragnisco, O.; Zullo, F. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    We construct Bäcklund transformations (BTs) for the Kirchhoff top by taking advantage of the common algebraic Poisson structure between this system and the sl(2) trigonometric Gaudin model. Our BTs are integrable maps ...
  • Bäcklund Transformations for the Trigonometric Gaudin Magnet 
    Ragnisco, O.; Zullo, F. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    We construct a Bäcklund transformation for the trigonometric classical Gaudin magnet starting from the Lax representation of the model. The Darboux dressing matrix obtained depends just on one set of variables because of ...
  • Backpressure at ECAP as a way for decreasing grain size and increasing ductility of UFG materials 
    Raab., G.I; Krasilnikov, N.A.; Valiev, R.Z. (Физика и техника высоких давлений, 2003)
    The investigation of the backpressure effect during equal-channel angular pressing (ECAP) on formation of ultrafine-grained (UFG) structure in pure copper has revealed that the increased hydrostatic pressure can contribute ...
  • Back-scattering and neutralization coefficients of nitrogen ions on iron surface 
    Kuzmichev, A.; Melnichenko, M. (Problems of Atomic Science and Technology, 2022)
    The coefficients of back-scattering and neutralization of nitrogen ions (N⁺) on iron surface during ion bombardment at the processes of ion sputtering and niriding have been calculated using TRIM code. The pure iron target ...
  • Back surface reflector optimization for thin single crystalline silicon solar cells 
    Kopach, V.R.; Kirichenko, M.V.; Shramko, S.V.; Zaitsev, R.V.; Tymchuk, I.T.; Antonova, V.A.; Listratenko, A.M. (Functional Materials, 2007)
    It has been shown that for single crystalline silicon solar cells (Si-SC) with 180-200 μm thick base crystals, the optimum back surface reflector (BSR) is TiO₂/Al with 0.18 μm thick oxide layer. At such BSR, the reflection ...
  • Backward electromagnetic waves in a magnetodisordered dielectric 
    Ivanchenko, E.A. (Физика низких температур, 2000)
    A nonlinear-evolution set of equations of the hydrodynamic type describing a magnet with a noncollinear arrangement of spins is investigated. An explicit expression invariant to right and left spin rotations is used for ...

    Stepanchikov, D.; Burykin, N.; Dyukova, T.; Ebrey, T.G.; Balashov, S.P.; Korchemskaya, E. (Functional Materials, 2006)
    We present our results on the optimization of light-induced anisotropy characteristics and holography recording on the films of genetically and chemically modified bacteriorhodopsin (BR), the photochromic retinal protein. ...

    Xiaojiang Guo; Shum, K.P. (Algebra and Discrete Mathematics, 2008)
    We consider Baer rings and Baer semisimple R-modules which are generalizations of semisimple modules. Several characterization theorems of Baer semisimple modules are obtained. In particular, we prove that a ring R is a ...

    Berceanu, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    We determine the matrix of the balanced metric of the Siegel-Jacobi ball and its inverse. We calculate the scalar curvature, the Ricci form and the Laplace-Beltrami operator of this manifold. We discuss several geometric ...

    Lukic, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    In this paper we show how Einstein metrics are naturally described using the quantization of the algebra of functions C∞(M) on a Kähler manifold M. In this setup one interprets M as the phase space itself, equipped with ...

    We show that every ballean (equivalently, coarse structure) on a set X can be determined by some group G of permutations of X and some group ideal I on G. We refine this characterization for some basic classes of balleans ...
