Submitting paper to journals and/or conferences in different fields I know there have been numerous questions on this site discussing the submission of papers to a conference and a journal (simultaneously and subsequently), but I'm curious about a slightly different scenario. Perhaps this is a duplicate but I couldn't find any answers already posted.

If I'm working in a field where there is cross-disciplinary work, is it okay to submit a paper to a journal or conference in each field? For example, a submitting to a medical journal for a novel medical application and a computer science conference for a novel algorithm? Obviously in one the focus would be more on the application of the approach while the other would focus on the "how", but the basic experiment/research and probably most of the content would be the same for both.
Two important things that you need to consider:


If the papers share any substantial amount of text, then you would be guilty of self plagiarism.  If this is discovered then its likely that one or the other or both papers will be rejected before publication or retracted after publication.  
In submitting to most conferences and journals a condition of publication is that your article is an original contribution.  If reviewers become aware of a duplicate publication of essentially the same research (even if the text is distinct) then they can and should reject the paper as not being an original contribution.  Some editors might retract a paper after publication if they discovered that you'd published essentially the same research elsewhere.  


It might be reasonable to submit two different papers to journals or conferences in different disciplines as long as the papers really do contain different material.  However, it's utterly inappropriate to reuse text or even to submit two papers that report essentially the same results. 

Statements by various publishers about duplicate submission/publication don't include any exception for publication in journals from different disciplines.   In short, the answer to your question is "no."
