Stochastic Control of Drawdowns via Reinsurance under Random Inspection
We consider a diffusion risk model where proportional reinsurance can be bought. In order to stabilise the surplus process, one tries to keep the drawdown, that is the difference of the surplus to its historical maximum, in an interval $[0,d)$. The o...

Cosmic ray spectrum and anisotropies from the knee to the second knee
We consider the scenario in which the knee in the cosmic ray spectrum is due to a change in the escape mechanism of cosmic rays from the Galaxy from one dominated by transverse diffusion to one dominated by drifts. We show that this scenario explai...
