Wolfgang R. Dick thanks for your help. The link does not mention how the publisher cooperates with ResearchGate.https://help.researchgate.net/hc/en-us/sections/14292301411217-Publishers.
I want to know how the publisher registered into ResearchGate,can you give me more favor ?
For more information, see https://www.researchgate.net/journal-home and the "Contact us" button at the end of the page. I am just a user of RG and do not have more details.
