Today, I want to specially congratulate my graduate student Itai Danieli for his newly accepted paper. This was one of the toughest professional adventures I experienced, but every round of reviews and rejections prompted Itai do improve the paper until this last version where one could not comment but accept. The process took some 14 months! To which I will add that the original idea and the mathematical developments are 100% Itai’s, which is indeed an outstanding achievement.
