Article in Press

To accelerate the online publication of accepted manuscripts, this journal supports the concept of “Articles in Press”. These are accepted peer-reviewed articles that have not yet been assigned to any volume/issue, but which are already citable using a DOI (for more information about DOIs, please visit http://www.doi.org/). An accepted article will be published online under ‘Articles in Press’ as soon as an uncorrected proof has been produced. This is the first version of the article which is citable using the DOI. Subsequently, once the corrected proof has been received the uncorrected version will be replaced by the corrected one. Note that once the final published version of the article (the ‘version of record’ or VOR) has been released and assigned to a volume/issue, the article can also be cited using issue and page numbers.
