If you make the following changes (and stick with biber), everything should work out just fine:
% \usepackage[utf8]{inputenc}
\usepackage{fontspec}
With fontspec you have a lot more font options anyway. I recommend typing texdoc fontspec at a terminal prompt (assuming you use TeX Live and aren't stuck on Windows).
An easy way to make your file compilable by either latex/pdflatex or lualatex would be (assuming no other packages are determining what you can or can't do):
\usepackage{ifluatex}
\ifluatex % LuaTeX
\usepackage{fontspec}
\defaultfontfeatures{Ligatures=TeX}
% load your system fonts; e.g.:
\setmainfont{LinLibertineO}
\setsansfont{LinBiolinumO}
\setmonofont{Inconsolata}
\else % pdfTeX
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
% load some Type 1 font; e.g.:
\usepackage[fulloldstylenums,largesmallcaps]{kpfonts}
\fi
Something similar could be done with the package ifxetex....
First thing to do is to add a field for the journal abbreviation to the article entrytype, journalabbr in the MWE. Therefore you need to declare a datamodel (an extra file; in the MWE I've used filecontents to simulate that) and you have to tell biblatex/biber to use it in the package options.
Then you have to modify the cite command, so it fits your needs. \citep from the authoryear-style (your citestyle) uses the \cite command. There you just have to add a switch, which checks if the field journalabbr is empty or not, and prints it out or not.
Last but not least you have to add the abbreviation fields to the entries.
MWE:
\begin{filecontents}{min.bib}

\printbibliography

On CentOS 7, biblatex.sty is not available. The command
yum provides "*biblatex.sty"return no results. I decide to use the natbib which is available and functionnal.Thanks
