JSE allows free and open access to full text articles (PDF) for all issues. The Journal depends in part on the payment of page charges for its operation. Payment of ￥200 Yuan (RMB, ~US$26) per printed page is expected from all authors who have funds available for that purpose. Requests for waiver of page charges should be submitted to the editorial office at jse@ibcas.ac.cn. Manuscripts are accepted or rejected purely on the basis of scientific merit. JSE will print color photographs, but authors must pay the additional cost at the following charges: ￥2000 (~US$260) for color figures (four-color process printing) per printed page, and ￥400 (~US$52) for high resolution black-and-white halftones (two-color process printing) per printed page.
