Query: New integrable boundary conditions for the q-deformed supersymmetric U
  model and Bethe ansatz equations   New classes of integrable boundary conditions for the q-deformed (or
two-parameter) supersymmetric U model are presented. The boundary systems are
solved by using the coordinate space Bethe ansatz technique and Bethe ansatz
equations are derived.
