Can Social Support on Facebook Influence Fertility Outcomes?

Social support is known to reduce stress and increase quality of life among patients undergoing IVF. Increasing social media use introduces a social support mechanism, yet data regarding the effect of this support on IVF outcomes are scarce. This observational, retrospective cohort study included women undergoing their first IVF cycle at an academic tertiary medical center.

Control of spontaneous emission in the presence of collisions.

We explore the coherent suppression of spontaneous emission processes in the presence of decoherence due to collisions with an external bath.

Complete suppression of spontaneous decay of a manifold of states by infrequent interruptions.

Complete suppression of spontaneous decay of a manifold of states is shown to be achievable in a model system by a combination of coherent excitation of overlapping resonances and a judicious infrequent application of microwave pulses.

Coherently controlled asymmetric synthesis with achiral light.

A laser-based method of increasing the enantiomeric excess of a chiral enantiomer in a racemic mixture is described. Neither the initial reagents nor the incident light need be chiral. Both formal and computational results show that enhancement of the enantiomer of choice, controlled by laser parameters, can be extensive.
