The broken DOI links of papers published since issue 3, vol. 14 (2013) were all corrected. All recent publications now have correct DOI links that can be referred to.
There is still a problem with DOI link of only issue number 2, vol. 14 (2013), that will take a little more time to solve. We kindly ask the authors having papers in this issue a little more patience, that the problem will be corrected in time.
We are available should any doubts appear on this matter.
