Query: Constructing regular self-similar solutions to the 3D Navier-Stokes
  equations originating at singular and arbitrary large initial data   Global-in-time smooth self-similar solutions to the 3D Navier-Stokes
equations are constructed emanating from homogeneous of degree -1 arbitrary
large initial data belonging only to the closure of the test functions in the
space of uniformly-locally square-integrable functions.
