Interested in submitting to this journal? We recommend that you review the About the Journal page for the journal's section policies, as well as the Author Guidelines. Authors need to register with the journal prior to submitting or, if already registered, can simply log in and begin the five-step process.
What changed
No manuscript has been accepted since 2015: there is no registration, no five-step process and no submission desk. The guidelines are kept because they describe how the published papers were handled, not because a window is open. Correspondence about a published paper goes to the editorial secretariat.
