An epidemic model with relapse and spatial diffusion is studied. Such a model is appropriate for tuberculosis, including bovine tuberculosis in cattle and wildlife, and for herpes. By using the linearized method, the local stability of each of feasible steady states to this model is investigated. It is proven that if the basic reproduction number is less than unity, the diseasefree steady state...

We introduce an integral structure in orbifold quantum cohomology associated to the K-group and the b Γ-class. In the case of compact toric orbifolds, we show that this integral structure matches with the natural integral structure for the Landau-Ginzburg model under mirror symmetry. By assuming the existence of an integral structure, we give a natural explanation for the specialization to a ro...

The story of the ox and oxherd, separate at first, but united in the realization of the inner unity of all existence, is an old Taoist story, updated and modified by a twelfth century Chinese Buddhist master to explain the path to enlightenment. The ox symbolizes the ultimate, undivided reality, the Buddha-nature, which is the ground of all existence. The oxherd symbolizes the self, who initial...
