Query: Fingerprints of classical diffusion in open 2D mesoscopic systems in the
  metallic regime   We investigate the distribution of the resonance widths ${\cal P}(\Gamma)$
and Wigner delay times ${\cal P}(\tau_W)$ for scattering from two-dimensional
systems in the diffusive regime. We obtain the forms of these distributions
(log-normal for large $\tau_W$ and small $\Gamma$, and power law in the
opposite case) for different symmetry classes and show that they are determined
by the underlying diffusive classical dynamics. Our theoretical arguments are
supported by extensive numerical calculations.
