Bridging the Dimensional Gap: from Kink in One Dimension to Curved   Domain Wall in Three Dimensions
  Improved expansion in width is applied to a curved domain wall in nonrelativistic dissipative $\lambda(\Phi^2 - v^2)^2 $ model with real scalar order parameter $\Phi$. Approximate analytic description of such a domain wall to second order in the width is presented.
