Query: Self-Organized Criticality and Intermittent Turbulence in an MHD Current
  Sheet with a Threshold Instability   We report numerical evidence of a self-organized criticality (SOC) and
intermittent turbulence (IT) symbiosis in a resistive magnetohydrodynamic (MHD)
current sheet model that includes a local hysteretic switch to capture plasma
physical processes outside of MHD that are described in the model as
current-dependent resistivity. Results from numerical simulations show
scale-free avalanches of magnetic energy dissipation characteristic of SOC, as
well as multi-scaling in the velocity field numerically indistinguishable from
certain hierarchical turbulence theories. We suggest that SOC and IT may be
complementary descriptions of dynamical states realized by driven current
sheets -- which occur ubiquitously in astrophysical and space plasmas.
