Effects of 5-fluorouracil on 5-fluorodeoxyuridine 5'-monophosphate and 2-deoxyuridine 5'-monophosphate pools, and DNA synthesis in solid mouse L1210 and rat Walker 256 tumors.

Abstract

A perfect bsp for a set S of disjoint line segments in the plane is a bsp in which none of the objects is cut. We study a specific class of bsps, called autopartitions and we prove that it is np-hard to find if a perfect auto-partition exists for a set of lines.
