Query: Material Line Fluctuations Slaved to Bulk Correlations in
  Two-Dimensional Turbulence   An analogy is pointed out between a polymer chain fluctuating in a
two-dimensional nematic background and a freely floating material line buffeted
by a two-dimensional turbulent fluid in the inertial (Kraichnan) regime. Under
certain conditions, the back-reaction of the line on the turbulent flow may be
neglected. The fractal exponent related to the size-contour relation of the
material line is connected to a "nematic" correlation function in the bulk.
