A study in the US has revealed that, apart from motion due to tides, seismic activity and other geophysical phenomena, the ground also moves entirely at random, at least over scales ranging from ...

Random walks in random environments constitute a pivotal area of research at the interface of probability theory, statistical physics and mathematical modelling. This field investigates stochastic ...

Juggling competing demands in a network of feverishly calculating computers drawing on the same memory resources is like trying to avert collisions among blindfolded, randomly zigzagging ice skaters.
