I understand Arxiv preprints are the way to go. But, I submitted a paper to an elsevier journal 2 months back. I am still to receive any review for it. I made a mistake of not putting in Arxiv before submitting it.
Now if someone does the same work as I have done. Can I complain about plagiarism based on the fact that I submitted the paper 2 months ago to the journal? Or, is Arxiv the only way to address this issue?
