Given a convex rational polytope $\Omega (b) := \{x \epsilon R_{+}^{n} \mid Ax = b\}$, we consider the function $b \mapsto f(b)$, which counts the nonnegative ...

We present some relations that allow the efficient approximate inversion of linear differential operators with rational function coefficients. We employ expansions in terms of a large class of ...

Peptoids, or n-substitued glycines, are complex and diverse oligomeric structures which have been explored for a number of biomimetic applications including drug delivery, surfactants, and catalysts.
