Our team effort is and will be continued. The meetings and the special work settings at ISSI have proven extremely useful for starting intense discussions which later on resulted in joint publications which would otherwise have not been possible in the given constellation of authors and ideas. New strong collaborations have been started which enriched our original perspective and objectives. We’d like to thank ISSI very much for the support of our project.
