Query: Uniqueness of positive solutions to semilinear elliptic equations with
  double power nonlinearities   We consider semilinear elliptic equations with double power nonlineaities.
The condition to assure the existence of positive solutions is well-known. In
the present paper, we remark that the additional condition to assure uniqueness
proposed by Ouyang and Shi is unnecessary.
