    We study quantum integrable models with GL(3) trigonometric R-matrix and solvable by the nested algebraic Bethe ansatz. Using the presentation of the universal Bethe vectors in terms of projections of products of the ...
  • Beyond Dualism Between Determinism and Voluntarism in Dynamic Economics, or Essay on the “Paradox of History-creating Decision” 
    Rozmainsky, I.V. (Економічний вісник Донбасу, 2013)
    The paper contains attempt to go beyond dualism between determinism and voluntarism in dynamic economics. On one hand, economic dynamics is not predetermined by tastes, endowments and technologies (as Neoclassical Economics ...
  • Beyond RPV Design Life 
    Ballesteros, A.; Garcia, G.; Bogede, L.; Bros, J. (Проблемы прочности, 2004)
    A set of standard reactor pressure vessels (RPV) surveillance programs for monitoring the design life (up to 40 years of reactor operation) have been analyzed. In view of the improved test methods and embrittlement ...
  • Beyond the Gaussian 
    Fujii, K. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    In this paper we present a non-Gaussian integral based on a cubic polynomial, instead of a quadratic, and give a fundamental formula in terms of its discriminant. It gives a mathematical reinforcement to the recent result ...
