Query: The Universal Scaling Exponents of Anisotropy in Turbulence and their
  Measurement   The scaling properties of correlation functions of non-scalar fields
(constructed from velocity derivatives) in isotropic hydrodynamic turbulence
are characterized by a set of universal exponents. It is explained that these
exponents also characterize the rate of decay of the effects of anisotropic
forcing in developed turbulence. This set has never been measured in either
numerical or laboratory experiments. These exponents are important for the
general theory of turbulence, but also for modeling anisotropic flows. We
propose in this letter how to measure these exponents using existing data bases
of direct numerical simulations and by designing new laboratory experiments.
