I quickly got three responses.
The first was from a member of the Advisory Editorial Board, Prof. Muhammad Aslam Noor of COMSATS Institute of Information Technology, Pakistan:
Many thanks for the information.
You may your own opinion about Prof. Ji-Huan He.
I would appreciate it very much if you please stop this nonsense, unprofessional and unethical character assassination of a leading mathematician and scientists.
Instead of this, you must appreciate his outstanding contributions to the scientific community.
I hope that you understand.
The second was from Managing Editor Prof. Barry Sanders of the Institute for Quantum Information Science at the University of Calgary:
I appreciate you raising this matter and am studying your web pages and original documents from SIAM and Elsevier. Before I make any decision I want to hear from various parties. The integrity of scientific publishing is paramount.
The third was from AMIS Editor-in-Chief Prof. Mahmoud Abdel-Aty of Sohag University, Egypt & University of Bahrain:
We thank you for your e-mail and we would like to inform you that we have formed a new committee from the Editorial Board to discuss the matter and investigate with high accuracy and objectivity this subject.
We will inform you of the decision of the Committee.
That's encouraging. If they keep He after investigating, I'm fine with it. The cases where there's no response at all are the ones that bother me.
