Query: Recent progress in the studies of neutron rich and high-$Z$ systems
  within the covariant density functional theory   The analysis of statistical and systematic uncertainties and their
propogation to nuclear extremes has been performed. Two extremes of nuclear
landscape (neutron-rich nuclei and superheavy nuclei) have been investigated.
For the first extreme, we focus on the ground state properties. For the second
extreme, we pay a particular attention to theoretical uncertainties in the
description of fission barriers of superheavy nuclei and their evolution on
going to neutron-rich nuclei.
