A geometric measure-type regularity criterion for solutions to the 3D   Navier-Stokes equations
  A local anisotropic geometric measure-type condition on the super-level sets of solutions to the 3D NSE preventing the formation of finite-time singularity is presented; essentially, local one-dimensional sparseness of the regions of intense fluid activity in a very weak sense.
