Prof. M.R. Setare (1972-2022)
We are deeply saddened to announce today that our friend, colleague, and member of JHAP editorial board passed away. He was one of the great physicists in the top 2% of scientists around the world. We would like to dedicate the forth volume (https://jhap.du.ac.ir/issue_64_65.html) to the memory of Prof. M.R. Setare.
