Query: On the algebra A_{\hbar,\eta}(osp(2|2)^{(2)}) and free boson
  representations   A two-parameter quantum deformation of the affine Lie super algebra
$osp(2|2)^{(2)}$ is introduced and studied in some detail. This algebra is the
first example associated with nonsimply-laced and twisted root systems of a
quantum current algebra with the structure of a so-called infinite Hopf family
of (super)algebras. A representation of this algebra at $c=1$ is realized in
the product Fock space of two commuting sets of Heisenberg algebras.
