Query: Coherence, space non-locality and lacunarity in a cascade model of
  turbulence   We use multiscale-multispace correlations and Fourier transform techniques,
to study some intermittent random field properties, which escape analysis by
structure function scaling. These properties are parametrized in terms of a set
of scale ratios, giving the typical interaction distances in space and scale of
the random field fluctuations, and the characteristic lengths over which these
fluctuations act coherently to generate intermittency. The relevance of these
techniques in turbulence theory is discussed.
