We study the generalization of quasipositive links from three-sphere to arbitrary closed, orientable three-manifolds. Our main result shows that boundary any smooth, properly embedded complex curve in a Stein domain is link. This generalizes due Boileau and Orevkov, it provides first half topological characterization three-manifolds which bound curves filling. arguments replace pseudoholomorphi...

This article concerns the canonical empirical Bayes problem of estimating normal means under squared-error loss. General empirical estimators are derived which are asymptotically minimax and optimal. Uniform convergence and the speed of convergence are considered. The general empirical Bayes estimators are compared with the shrinkage estimators of Stein (1956) and James and Stein (1961). Estima...
