This article aims to provide a coherent foundation for empirical studies of interpersonal discussion on risk.

Some species of proteins which can form liquid-like condensates, also exhibit growth into fibers (or fibrils). One particularly interesting set of such proteins are those that are associated with neurodegeneration in which the fiber growth may be related to the pathological fibrils observed in disea…

In the Netherlands, levying tax on inheritances at death has been a fact of life for centuries. The presumed double taxation and its sad precursor are elements of the discussion about the levy of this inheritance tax, but so too are the possibilities to reduce the tax through ingenious legal constru…

Nonadiabatic energy transfer from the translational motion (T) of a molecule impinging on metal surface to the metal’s electrons may determine whether the molecule can lose enough energy to adsorb or react.

Violence during war often involves upswings and downturns that have, to date, been insufficiently explained. Why does violence at a particular point in time increase in intensity and why do actors in war decrease the level of violence at other points?
