Current-voltage characteristics were investigated in highly anisotropic , and isotropic single crystals which were irradiated in the direction parallel to the c-axis. In the range of magnetic fields from to (where is the matching field), same scaling functions can be used to describe the transition in those two systems. The field- and sample-independent critical exponents, which were found to be , using , are in a very good agreement with numerical simulations for strongly screened vortex line interactions. Moreover, the obtained scalings are the same despite a large difference in anisotropy.
