    "abstract": "We construct an extended Hubbard model with open boundaries from a $R$-matrix\nbased on the $U_q[Osp(2|2)]$ superalgebra. We study the reflection equation and\nfind two classes of diagonal solutions. The corresponding one-dimensional open\nHamiltonians are diagonalized by means of the Bethe ansatz approach.",
