  Energetic partons traveling in a strongly interacting medium lose energy by
emitting radiation and through collisions with medium constituents.
Non-perturbative, next-to-leading order and leading order collision kernels are
implemented within AMY-McGill formalism. The resulting gluon emission rates are
then evaluated and compared by considering scattering occurring in a brick of
quark-gluon plasma, as well as in a realistic simulation of Pb-Pb, collisions
at $\sqrt{s}=2.76$ ATeV using MARTINI. We find that the variations in quenching
of hard partons resulting from using different kernels can be important,
depending on the overall value of the strong coupling constant $\alpha_s$.
