Last year, Aston published a paper called “Is radioactive decay really exponential?” (Euro Phys Lett 97 52001). The paper questioned the almost universally accepted belief that radioactive decay is always exponential. He considered various arguments that suggest that slowly decaying isotopes may decay non-exponentially, which is hard to verify experimentally due to the long timescales […]

The article “Nonlinear energy transfer between fluid sloshing and vessel motion” has been accepted for publication in the Journal of Fluid Mechanics. The article examines the dynamic coupling between a sloshing fluid and the motion of the vessel containing the fluid. A nonlinear mechanism is identified which leads to an energy exchange between the vessel […]

Jon Bevan will be giving a talk in the PDE seminar at Oxford on Monday 14th January on “N-covering stationary points and constrained variational problems”. The talk will show how degree N maps of the form u_N(z) = frac{z^N}{|z|^{N-1}}} arise naturally as stationary points of functionals like the Dirichlet energy. Moreover it is shown that […]
