In this folder we present articles that have been sent for publication in our journal and have successfully passed the review stage. The article text will still be given to editorial and technical processing. They have not yet been assigned to a specific volume and do not have specific page numbers, but they have been given a final registered DOI number, so they can already be cited in other publications. The final version of the articles will appear in upcoming issues of the journal and then the assigned DOI of each article will be registered in the CrossRef and other databases.
