Dear WG4 conveners, There are a few abstracts that have been submitted both to WG2 and WG4: #212, #369, #313, #163, #366 and #347. Out of these, we are considering to accept #366 as a talk, and #347 probably as a poster. On the other hand, #369 has been submitted by authors with Russian affiliations, and it is not yet clear how we should proceed in such a case. Due to the number of abstracts that we received, it is not possible for us to accommodate the abstracts number #212, #313 and #163. Can you please consider these abstracts, keeping in mind that we will not be able to accept them in WG2?
