Here, the authors introduce the concept of Janus acoustic metascreen for independent wavefront manipulations for two opposite incidences. They use acoustic circulators with rotating inner cores to achieve high nonreciprocity, and demonstrate tunable

International audience; In 1964, a set of 53 Buddhist bronze statues were discovered at Prakhon Chai (Buriram province, Thailand) without any indication of the origin of the statues nor the reason of their presence. The stylistic study of some of the
