Site upgrade on May 16, 2018


Dear authors,

we will be upgrading the site to version 3.1 on Wednesday, May 16, 2018. The journal will not be accessible during most of the day and we may experience some issues during the next few weeks. All information, submissions and reviews will not be affected by the upgrade.

Please report any problems with the website to

Kind regards,
