One-loop corrections to the fermion rest mass M_1, wave functionrenormalization Z_2 and speed of light renormalization C_0 are presented forlattice actions that combine improved glue with clover or D234 quark actionsand keep the temporal and spatial lattice spacings, a_t and a_s, distinct. Weexplore a range of values for the anisotropy parameter \chi = a_s/a_t and treatboth massive and massless fermions.Comment: 45 LaTeX pages with 4 postscript figure

One-loop self-energy and renormalization of the speed of light for some anisotropic improved quark actions
