A Pad\'e-aided analysis of nonperturbative $NN$ scattering in $^1S_0$   channel
  We carried out a Pad\'e approximant analysis on a compact factor of the $T$-matrix for $NN$ scattering to explore the nonperturbative renormalization prescription in a universal manner. The utilities and virtues for this Pad\'e analysis were discussed.
