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 ...

Protein improvement strategies today involve widely varying combinations of rational design with random mutagenesis and screening. To make further progress—defined as making subsequent protein ...
