Enter your abstract here. Usage of formulas
\[a^2+b^2=c^2\]
and figures is allowed as long as you don't change anything in the preamble (except for filling title and author information) and do not exceed one page. Font size and margins of the template are small, so there is enough space on the single space for the abstract.

You~\cite{refA,refB} can also use up to five references~\cite{refC}.
If you need to include graphics files, please submit a zip archive containing your tex file and the necessary graphics files. Acceptable file formats for the graphics files are only JPG, PNG and PDF. Figure~\ref{fig:myfig} shows an example plot that doesn't need any graphics files.
