TL;DR: In this article, the number-phase uncertainty products proposed by Carruthers and Nieto are studied to determine whether they are minimized by coherent states, and it is found that coherent states do not minimize these products.
Abstract: The number‐phase uncertainty products proposed by Carruthers and Nieto are studied to determine whether they are minimized by coherent states. It is found that coherent states do not minimize these products. States that do minimize some of the uncertainty products are constructed. Variational techniques for the study of arbitrary uncertainty products are developed.

TL;DR: In this article, a UML profile for software product lines is proposed, which includes stereotypes, tagged values, and structural constraints, making it possible to define PL models with variabilities.
Abstract: This paper proposes a UML profile for software product lines. This profile includes stereotypes, tagged values, and structural constraints and it makes possible to define PL models with variabilities. Product derivation consists in generating product models from PL models. The derivation should preserve and ensure a set of constraints which are specified using the OCL.
