Query: Universal size properties of "star-ring" polymer structure in disordered
  environment   We consider the complex polymer system, consisting of ring polymer connected
to the $f_1$-branched star-like structure, in good solvent in presence of
structural inhomogeneities. We assume, that structural defects are correlated
at large distances $x$ according to a power law $~x^{-a}$. Applying the direct
polymer renormalization approach, we evaluate the universal size
characteristics such as the ratio of the radii of gyration of star-ring and
star topologies, and compare the effective sizes of single branches in complex
structures and isolated polymers of the same total molecular weight. The
non-trivial impact of disorder on these quantities is analyzed.
