    NNLO anomalous dimension matrix for twist-two flavor-singlet operators by V.M. Braun, K.G. Chetyrkin, A.N. Manashov

    Published 2022-11-01
    “…We show that this property allows one to calculate off-diagonal parts of the anomalous dimension matrices for leading-twist operators from a set of two-point correlation functions of gauge-invariant operators which can be evaluated using standard computer algebra techniques. As an illustration, we present the results for the NNLO anomalous dimension matrix for flavor-singlet QCD operators for spin N≤8.…”

    Computer Simulation of Stochastic Energy Fluctuations in Tensile Test of Elasto-Plastic Porous Metallic Material by Marcin Kamiński, Michał Strąkowski

    Published 2020-01-01
    “…The metal porous plasticity model applied here is based on Gurson&#8722;Tvergaard&#8722;Needleman theory and is included in the ABAQUS finite element system, while the external probabilistic procedures were programmed in the computer algebra system MAPLE 2017. Hybrid usage of these two computer systems enabled the determination of fluctuations in elastic and plastic energies due to initial variations in the ratio of the metal micro-voids, and the calculation of the first four probabilistic moments and coefficients of these energies due to Gaussian distribution of this ratio. …”
