Dear authors,
we will soon close the reviewing process, and submit all accepted papers to Springer Nature for the publication process. We would like to distribute all published books to the WLF4 participants in Ljubljana during the WLF4.
Any further delays are not possible anymore, please, finish the revisions and upload the revised versions of the manuscript before January 9, 2017.
All the best in 2017,
Matjaž Mikoš
Editor-in-Chief
