We meet every Monday at 1.30pm to discuss the new developments in the fields of research relevant for GRAPPA members and affiliates. The idea is to discuss briefly, with the help of a projector, the results of ~5 interesting papers recently appeared on the arXiv, or anywhere else. Please choose one posted e.g. this week in your field and tell us about it in 5-10 minutes. Feel free to join us even if you haven't read anything.
