Space group Cc: an update.

Space groups P1 and Cc: how are they doing?

A survey of recent entries in the Cambridge Structural Database suggests that the percentage of structures described in space groups of inappropriately low symmetry has decreased from about 10% in the early 2000s to less than 5% today for space group Cc, but that for space group P1 it remains close to 8%.

The perils of Cc revisited

The space groups of 98 structures originaJly reported in Cc are revised. In 75 cases the revised space group is C2/c and the revision entails adding a center of symmetry, usually leading to large changes in bond lengths and angles. In the remaining 23 cases, where the revised space group is Fdd2, R3c or (in one case) 14c2, the lattice type is changed but no center is added; in these cases the m...

The role of metformin in polycystic ovary syndrome: a systematic review.

This meta-analysis evaluated the effectiveness of metformin in subfertile women with polycystic ovary syndrome (PCOS). Only randomized trials investigating the effectiveness of metformin and PCOS definition consistent with the Rotterdam consensus criteria, were eligible. Primary outcome was live birth rate. A literature search identified 27 trials. In therapy naïve women, we found no evidence o...

Spaces of Maps into Topological Group with the Whiteny Topology

Let X be a separable locally compact metrizable space and G a separable completely metrizable ANR topological group without isolated points. By C(X, G), we denote the topological group of all continuous maps f : X → G endowed with the Whitney (graph) topology and by Cc(X, G) the subgroup consisting of all maps with compact support. It is known that if X is compact and non-discrete then the spac...
