UNSTRUCTURED Dear Editor, Per your instruction, I have submitted a formal request to withdraw our manuscript 18108 on June 11th with an explanation for the withdraw and a scan of the signed letter. The same letter has been uploaded to your online system as well. I am sending this withdraw letter again due to the “request for a revised manuscript” email get to us again! Feel free to contact me should you have any question. But, please help DO NOT send any further junk mail to 40+ co-authors. It is really bad that we have submitted the withdraw petition several times with an explanation, but the system is still sending emails to all authorships. Best regards, Jian-Bing Fan (the corresponding author)
