In most cases, there is a conflict among the authors about their position and role in the article. Recently, many journals specify the authors contribution with their position. Usually the PI, Lab Head, Project Leader will act as corresponding author.
Now, what is your opinion dear fellow/peers about the authorship and contributors of the article.
Do you think any authors number limit for popular cited articles?? All co author will benefits from the citation similarly? How a first author will benefits more than the citation in such case?
