[Tex/LaTex] Set limit on number of authors in citation call-out when using the IEEEtranN bibliography style

bibliographiesbibtexieeetran

I know the thread Set limit to one author when using “et al.” in biblatex but this thread is about BibTeX.

Code where bibliography in BibTeX

\documentclass{beamer}

\setbeamertemplate{bibliography item}{\insertbiblabel} % I think not necessary

\begin{document}
\begin{frame}
\frametitle{Cesarean Section and Epidemiology}

\begin{itemize}
\item First Modern C-section by Ferdinand Adolf Kehrer 1881. \cite{history_c_section}
\item Surgical procedure where one or more incisions are made through a mother's abdomen and uterus to deliver one or more babies.
\item 2012, 23M globally. \cite{molina} 10-15\% of all. \cite{who_c_section} but >19\% better? 
\end{itemize}

\bibliographystyle{IEEEtranN}
\bibliography{task}

\end{frame}

Task.bib

@book{ history_c_section,
  author = "Dadebo, Dr. Benjamin",
  year = 2012,
  title = "Begat By God: Understanding the Concept of Being Born Again",
  publisher = "Xlibris Corporation",
  pages = "31–",
  note = "ISBN 978-1-4771-0612-9"
}

@article{ who_c_section,
  author = "WHO",
  title = "{WHO Statement on Caesarean Section Rates}",
  year = 2015,
  note= "[Online; accessed 7-Feb-2015]"
}

@article{ molina,
  author = "Molina, G and Weiser, TG and Lipsitz, SR and Esquivel, MM and Uribe-Leitz, T and Azad, T and Shah, N and Semrau, K and Berry, WR and Gawande, AA and Haynes, AB",
  year = 2015,
  title = "{Relationship Between Cesarean Delivery Rate and Maternal and Neonatal Mortality}",
  journal = "JAMA 314",
  volume = "21",
  pages = "2263–70"
}

Output in one page where you see the problem with Molina

Complication After adding `\usepackage{natbib}` in beginning

Mico's solution solves the initial bug but causes a complication.
I get the strange top-bar references in each slide

Why is there the references top-bar?

How can you limit the amount of authors in the bibliography of Beamer?

Since you're using the IEEEtranN bibliography style -- hint: the final N in IEEEtranN stands for "natbib" -- you should load the natbib citation management package. Once you do that, you'll get the desired, i.e., truncated list of authors in the citation call-outs generated by \cite.

[Tex/LaTex] how to get the string “submitted” into the citation call-out when using the apalike bibliography style

You will need to modify the bibliography style file -- here: apalike.bst -- to get BibTeX/LaTeX to print "submitted" rather than "tted" in the citation call-outs. I suggest you proceed as follows:

Find the file apalike.bst in your TeX distribution. Make a copy of this file, and name the copy (say) myapalike.bst. (Don't edit an original file of the TeX distribution directly.)
Open the file myapalike.bst in a text editor; the editor you use to edit your tex files will do fine.
In myapalike.bst, find the function calc.label. (In my copy of this file, the function starts on line 896.)
In this function, locate the following line:
```
  year field.or.null purify$ #-1 #4 substring$ 
```
In case you're curious: the instruction purify$ #-1 #4 substring$ extracts the final four characters from the year string. Usually, this will be the ordinary four-numeral year string; in the case at hand, though, it's "tted".
Change this string to
```
  year field.or.null 
```
i.e., delete the purify$ #-1 #4 substring$ part.
Save the file myapalike.bst, either in the directory where your main tex file is located or in a directory that's searched by BibTeX. If you choose the latter option, be sure to update the filename database of your TeX distribution appropriately.
Start using the modified bibliography style by changing the argument of the \bibliographystyle macro. Be sure to re-run LaTeX, BibTeX, and LaTeX twice more to fully propagate all changes.

Consider the following MWE that's based on your code snippets:

\RequirePackage{filecontents}
\begin{filecontents}{myref.bib}
@preamble{ " \newcommand{\noop}[1]{} " }
@article{author2015,
  author  = "Author Author", 
  title   = "Some Title",
  journal = "Some Journal",
  year    = "\noop{2015}submitted",
}
\end{filecontents}

\documentclass[11pt,a4paper, twoside]{article}
\usepackage[authoryear]{natbib}
\begin{document}
A study by \citet{author2015}
\bibliographystyle{myapalike}
\bibliography{myref}
\end{document}

After running LaTeX and BibTeX, the file \jobname.bbl -- the file that contains the sorted and formatted bibliographic entries -- looks like this:

 \newcommand{\noop}[1]{}
\begin{thebibliography}{}

\bibitem[Author, \noop{2015}submitted]{author2015}
Author, A. (\noop{2015}submitted).
\newblock Some title.
\newblock {\em Some Journal}.

\end{thebibliography}

Observe that the term \noop{2015}submitted occurs twice. It occurs first in the optional argument of the \bibitem instruction. The optional argument is used by natbib to format the citation call-out. E.g., \citet{author2015} will generate Author (\noop{2015}submitted), and \citep{author2015} will generate (Author, \noop{2015}submitted). In both cases, LaTeX will then evaluate \noop{2015}, making the citation call-outs look like Author (submitted) and (Author, submitted), respectively.

The term \noop{2015}submitted occurs again later on, this time surrounded by parentheses. Of course, (\noop{2015}submitted) is evaluated by LaTeX to (submitted), and that's what you see in the typeset output.
