I recall that Short Time Scientific Missions (STSMs) are a great opportunity for all scientists within the COST Action to exchange visits and strengthen collaborations. In 2015 there will be three different calls for STSMs covering the periods: Jan-April, May-Aug, and Sept-Dec.
Applications are now invited for the first round of STSMs. The approved STSMs will therefore take place between 01.01.15 and 30.04.15. Applications outside this timeframe will be discarded.
The deadline for applications is set to be December 7, 2014, so that the results of the evaluation can be made available before the Christmas break.
