Hi,<br />I know you have not edited this paper. I submited this file last night. When I tried to download the file to confirm if I uploaded successfully, I was told&nbsp;The document you requested was not found. So maybe there are some problems about the upload system. Then I sent you a message and attached the file. &nbsp;I have paided I am sure the editor I chose was you.&nbsp;<br />Thank you so much.
