The correlation between inertial-range velocity fluctuations
and energy dissipation in fully developed turbulence is studied
using high-resolution direct numerical simulation.
Runs with microscale Reynolds number up to
have been performed
in order to achieve the maximum extent of the scaling range compatible
with a proper resolution of the dissipative scales.
The bridge relations, a set of scaling relations
which express quantitatively the statistical dependence
of dissipation-scale velocity fluctuations
on inertial-range ones, are verified.
