With deep regret and sorrow we have just heard from our Ukrainian colleague Liudmyla Deretska that Nikolai Kyryliuk had passed away after a heart attack in February earlier this year. Liudmyla writes that Nikolai, who was only 53, will stay in the memory of his colleagues as a very kind, calm, and nice person, always open hearted, devoted to his work and to the care of his family. We are going to remember Nikolai during the incoming B09 conference.
