Measurement-induced quantum walks

Quantum systems generally lack precise trajectories. Hence, the notion of a quantum random walk is somewhat problematic. One way to make the idea precise is to consider quantum evolution which is repeatedly interrupted by position measurements, each of which localises the system to a particular state. Read more

Afterslip Moment Scaling and Variability from a Global Compilation of Estimates

Aseismic afterslip is the gentle slipping or sliding of a fault over several months or years following an earthquake. The process involves aseismic shear and post-seismic readjustment occurring on and close to the fault planes of the parent earthquake, quite distinct from generally deeper and more distributed viscoelastic relaxation.

Forecasting new diseases in low-data settings using transfer learning

Epidemic models fall into two broad categories – those which fit an epidemic curve to past data in order to make predictions about the future, and mechanistic models which simulate more general scenarios based on specific underlying assumptions on factors such as varying contact rates Read more
