Advection-Diffusion Equations for Internal State-Mediated Random Walks
Abstract. In many biological examples of biased random walks, movement statistics are determined by state dynamics that are internal to the organism or cell and that mediate respon...

Theoretical Cryptanalysis of the Klimov-Shamir Number Generator TF-1
The internal state of the Klimov–Shamir number generator TF-1 consists of four words of size w bits each, whereas its intended strength is 22w. We exploit an asymmetry in its out...
