3D printing as an additive manufacturing method has proven to be of great interest for the computerized production of oral splints. Various parameters must be taken into consideration when assessing the durability of oral splints in a wet environment, such as the mouth. The aim of this in vitro study was to assess the wear behavior and water sorption of two 3D-printed splint materials depending on their building orientation and post-processing parameters.

- This study examines how the placement of plane-parallel ionization chambers affects the calculation of specific factors and beam quality correction factors in proton beams.
- Monte Carlo simulations were used to analyze six ionization chamber types with different positioning methods, showing significant differences, especially in areas with steep dose gradients.
- The findings indicate that using the effective point of measurement as recommended by the updated TRS-398 code may introduce systematic errors in the correction factors for these chambers, potentially impacting dosimetry accuracy.
Diazirines are versatile carbene precursors that are extensively used in biological target identification experiments. However, their photo-activation wavelength ( 365 nm) precludes their use in living organisms. Here we show that a reconceptualization of the diazirine hybridization state leads to conjugation of the diazirine motif to longer-wavelength chromophores.

- The study focuses on detecting multijet signatures from proton-proton collisions at a high energy of 13 TeV, analyzing a dataset totaling 128 fb^{-1}.
- A special data scouting method is utilized to pick out events with low combined momentum in jets.
- This research is pioneering in its investigation of electroweak particle production in R-parity violating supersymmetric models, particularly examining hadronically decaying mass-degenerate higgsinos, and it broadens the limits on the existence of R-parity violating top squarks and gluinos.
Background: Treatment planning in radiation therapy (RT) is performed on image sets acquired with commercial x-ray computed tomography (CT) scanners. Considering an increased frequency of verification scans for adaptive RT and the advent of alternatives to x-ray CTs, there is a need to review the requirements for image sets used in RT planning.
Purpose: This study aims to derive the required image quality (IQ) for the computation of the dose distribution in proton therapy (PT) regarding spatial resolution and the combination of spatial resolution and noise.
