全文都是开放获取，但不缴费出版费：
Open access
Every peer-reviewed research article appearing in this journal will be published open access. This
means that the article is universally and freely accessible via the internet in perpetuity, in an easily
readable format immediately after publication. The author does not have any publication charges for
open access. The King Saud University will pay to make the article open access.

想知道到底收不收版面费呢。。。
