Two-dimensional topological states of matter offer a route to quantum computation that would be topologically protected against the nemesis of the quantum circuit model: decoherence. Research groups in industry, government and academic institutions are pursuing this approach. We give a mathematicians perspective on some of the advantages and challenges of this model, highlighting some recent ad...

BACKGROUND An unresolved issue in psychiatry research concerns the assumption that detrimental effects of negative life events on mental health may be buffered by a multitude of positive life events. However, there is clear lack of empirical evidence for this assumption, and one may even argue that positive life events act as additional stressors and thus increase (and not decrease) the risk fo...

Heterogeneity, ranging from measurement error to variation among individuals or regions, influences all levels of data collected for risk assessment. In its role as a nemesis, heterogeneity can reduce the precision of estimates, change the shape of a population model, or reduce the generalizability of study results. In many contexts, however, heterogeneity is the primary object of inference. In...
