Query: Numerical evaluation of some master integrals for the 2-loop general
  massive self-mass from differential equations   The 4-th order Runge-Kutta method in the complex plane is proposed for
numerically advancing the solutions of a system of first order differential
equations in one external invariant satisfied by the master integrals related
to a Feynman graph. Some results obtained for the 2-loop self-mass MI are
reviewed. The method offers a reliable and robust approach to the direct and
precise numerical evaluation of master integrals.
