Time to relax the rules about administration of mifepristone.
Pre-clinical and clinical data indicate that mifepristone is a safe and effective drug for the termination of pregnancy. The author suggests that it could be given by nursing staff rather than by a doctor, and that the 2-hour post-administration observation period is unnecessary in the majority of cases.

متن کاملHow to Relax a Bisimulation?
Merge-and-shrink abstraction (M&S) is an approach for constructing admissible heuristic functions for cost-optimal planning. It enables the targeted design of abstractions, by allowing to choose individual pairs of (abstract) states to aggregate into one. A key question is how to actually make these choices, so as to obtain an informed heuristic at reasonable computational cost. Recent work has...
متن کاملTighten after Relax: Minimax-Optimal Sparse PCA in Polynomial Time
We provide statistical and computational analysis of sparse Principal Component Analysis (PCA) in high dimensions. The sparse PCA problem is highly nonconvex in nature. Consequently, though its global solution attains the optimal statistical rate of convergence, such solution is computationally intractable to obtain. Meanwhile, although its convex relaxations are tractable to compute, they yiel...
