I've recently noticed that some researchers are publishing papers in the same (or similar) IEEE journals where I've previously submitted (a year ago), covering topics closely related to my work. However, none of these papers cite my relevant paper on the same subject.
For instance, I recently found a paper in early access (not the final version) that I believe lacks a thorough analysis. In my view, referencing my work would have strengthened their discussion, as I addressed the same question a year ago. I’m genuinely puzzled as to how they could have overlooked such a relevant piece of research.
What would be the best way to address this with the journal? Would it be inappropriate to inform the authors directly?
