Dear Colleague, 
       
As you may know by now, recently Combustion and Flame (CNF) transitioned from the Elsevier Editorial System (EES) to Editorial Manager (EM). The transition was relatively smooth (with very few exceptions) and we believe that EM is a better platform compared to EES.
         
With this note, we want to bring to your attention two important changes as indicated now in the updated CNF Guide for Authors.  
        

The first change is that manuscripts from France and Germany must now be submitted to the US Office. More specifically, it is stated in the Guide for Authors that:

• All manuscripts originating in the Americas, Australia and Oceania, France, Germany, Russia, Middle East (except Iran), and all of Asia (except China) should be sent to Professor Fokion N. Egolfopoulos, while those originating elsewhere from Europe (except France and Germany) Africa, China, and Iran should be sent to Dr. Thierry Poinsot.

The second change is that special attention is needed when an earlier version of a paper has been submitted to a conference, which has been a point of controversy in recent years. As a result, we have decided that specific language needs to be introduced in order to minimize double counting by search engines (that index scholarly literature), when the same work receives multiple DOI numbers.
  
More specifically, it is stated now in the Guide for Authors that:

• To verify originality, all submitted articles are checked automatically upon submission by the iThenticate software. If an earlier version of the work has been submitted to a conference, there are two topics that require attention. First, transferring copyright to the society organizing the conference automatically disqualifies a manuscript from further consideration. Additionally, conference manuscripts with a DOI number assigned to them will be identified by iThenticate. In those cases, the authors must disclose in the cover letter or a separate document the major differences between the two manuscripts. If such disclosure is not made, the editors will use the similarity index as the basis to either disqualify a manuscript from further consideration or to request a disclosure from the authors.   
  

With our best regards,
Fokion Egolfopoulos and Thierry Poinsot
