See image below for reference.
The keywords and DOI are displayed below abstract. A line space between abstract, keywords, and DOI and bold face for Keywords and DOI would be nice. There is a extra line for Keywords and also DOI at the bottom of the page. I would like to remove both. I looked at the article.tpl page but can’t find where to make the changes (I could remove the DOI at the bottom). Any help will be appreciated.
