By changing systematically the shear rates that symbolize the degree of differential rotation in nascent proto-neutron stars (PNSs), we derive a scaling relation between the turbulent stress sustained by the MRI and the shear- vorticity ratio. Our parametric survey shows a power-law scaling between the turbulent stress ($<< w_{\\rm tot}>>$) and the shear- vorticity","authors_text":"K. Kotake, T. Sano, T. Takiwaki, Y.
