COLLABORATION AND AUTHORSHIP LEVEL

The following model is suggested to define collaboration and authorship level:

-  Conceptualization : X.X. and X.X.;  Data Curation : X.X. and X.X.;  Formal Analysis : X.X. and X.X.;  Funding Acquisition : X.X. and X.X.;  Investigation : X.X. and X.X.;  Methodology : X.X. and X.X.;  Project Administration : X.X. and X.X.;  Resources : X.X. and X.X.;  Software : X.X. and X.X.;  Supervision : X.X. and X.X.;  Validation : X.X. and X.X.;  Visualization : X.X. and X.X.;  Writing – Original Draft : X.X. and X.X.;  Writing – Review & Editing : X.X. and X.X.

- Before the References section, a paragraph detailing each author's contribution should be added, listing authors by their initials. It is not mandatory to complete all roles; they can be omitted if necessary.

- Authorship should be limited to those who have substantially contributed to the communicated work.
