Moving Breather Collisions in the Peyrard-Bishop DNA Model
We consider collisions of moving breathers (MBs) in the Peyrard-Bishop DNA model. Two identical stationary breathers, separated by a fixed number of pair-bases, are perturbed and b...

On the Salsa20 Core Function
In this paper, we point out some weaknesses in the Salsa20 core function that could be exploited to obtain up to 231 collisions for its full (20 rounds) version. We first find an i...
