The publication describes complex support structures and scaffolds for stem cells and organoids. Consideration of geometric and structural parameters has an influence on stem cell development and organogenesis comparable to that of molecular genetics and biochemical parameters. [...]

Beam phase control loops have become an important sub-system of the low-level radio frequency (LLRF) systems of ion synchrotrons. A wide range of different implementations exists today. [...]

Objective.Accurate estimation of tissue stopping power ratios (SPRs) from computed tomography (CT) data is essential in charged particle therapy (CPT), yet it remains a major source of range uncertainties. While various SPR calibration methods have been developed for clinical CT scanners, they are not tailored to cone beam type Micro CT scanners commonly used in pre-clinical studies involving small animals.
