Hello, Jinping Wang - I'm looking forward to working on your manuscript, and thank you for your note, that's very helpful.&nbsp;&nbsp;&nbsp;Because I'm not a subject-matter expert in your field, my ability to edit for content is limited, but I can make suggestions and will be glad to think about tightening up the text and the logical flow of argument.&nbsp; Thanks again for allowing me to work with you.&nbsp; RebeccaTDE
