OBJECTIVE The effects of Yigu Capsule on NO and NOS of osteoblasts were studied. METHODS (1) Forty 12-month old Sprague-daweley female rats were divided into randomly four groups (Yigu Capsule high dose group, medium dose group and low dose group; saline group), the drug-containing serum and control serum were prepared. (2) The new-born Sprague-daweley(More)
A new compact difference scheme is proposed for solving the nonlinear Schrödinger equation. The scheme is proved to conserve the total mass and the total energy and the optimal convergent rate, without any restriction on the grid ratio, at the order of O h8 τ2 in the discrete L∞-norm with time step τ and mesh size h. In numerical analysis, beside the(More)
