How Crime Responds to Deterrence: A Modeling Perspective

Modelling and understanding how crime responds to deterrence is an interesting yet ambitious undertaking. Crime is shaped by a web of social environments, economic incentives, institutional structures, and individual decision-making. Any formal model, no matter how sophisticated, must necessarily simplify this reality to make the problem analytically tractable

The secrets of espresso brewing

During the brewing process of an espresso, hot water flows through a cylindrical filter that is densely packed with coffee grounds. Along the way, chemicals are extracted such that the liquid leaving the filter is not pure water anymore, but espresso. The concentration of dissolved chemicals in the liquid that comes out of the machine is the quantity of interest in a wide range of mathematical models for espresso brewing.

Magnetic fields and imaging technologies

Magnetic fields are at the core of many imaging technologies. A widely known modality is MRI, a standard procedure in medical imaging, which is however limited by a long scanning time and the ability to only image anatomical regions containing sufficient amounts of water. The more recent magnetic particle imaging (MPI) instead promises functional images of the dynamics of nanoparticle tracers with high temporal resolution.
