W−Re alloys were prepared by powder metallurgy. The effect of annealing temperature on the microstructure and properties of the W−Re alloys were investigated by tensile mechanical properties testing, hardness testing, and optical microscope analy

We study the problem of counting lattice points of a polytope that are weighted by an Ehrhart quasi-polynomial of a family of parametric polytopes. As applications one can compute integrals and maximum values of such quasi-polynomials, as well as obt

In this paper, we explore affine semigroup versions of the convex geometry theorems of Helly, Tverberg, and Caratheodory. Additionally, we develop a new theory of colored affine semigroups, where the semigroup generators each receive a color and the
