The earliest cost data in our repository Gutenberg Open Science (DSpace) date back to 2022. Currently, all data is stored internally, but growing interest in cost transparency has prompted a first try at implementing openCost. [...]

Contemporary particle accelerators allow for the generation of a narrow pencil beamof electrons which can be scanned to deliver a clinical dose distribution at an ultra-high (FLASH)dose rate. This study develops a radiotherapy beam model and discrete ordinates Boltzmann solverfor such an accelerator and then applies the method to treatment planning for superficial brainmetastases. [...]

Ultralight dark matter may couple quadratically to Standard Model particles. Such quadratic interactions give rise to both coherent and stochastic signals in pulsar timing array (PTA) observations. [...]

Dynamics, morphology, and structure of glassy water are highly relevant for cryochemical techniques, in particular for cryo–electron microscopy. Here, we study the structural dynamics of a deposit consisting of thousands of micrometer-sized glassy water droplets during and after droplet coalescence using x-ray photon correlation spectroscopy at the micro- and meso-scale. [...]

The large van der Waals gap in transition metal dichalcogenides (TMDs) offers an avenue to tune the ground state of 2D materials through the intercalation of magnetic atoms. Here, we investigate the charge correlations in Fe1/3⁢TaS2, Co1/3⁢TaS2, and Fe0.35⁢NbS2 by combining angle-resolved photoemission spectroscopy (ARPES), x-ray scattering, magnetometry, and density functional theory (DFT) [...]

Residual stresses were quantified in a 316 L stainless steel additive manufacturing benchmark arch to assess part-to-part and machine-to-machine variability and the influence of baseplate during stress-relief heat treatment. Nominally identical arches were built by laser powder bed fusion (LPBF) on a MetalFAB1 and an EOS M290 using each vendor’s recommended process window, then characterized by synchrotron and neutron diffraction. [...]

Non-destructive Schottky detectors are indispensable devices widely used in experiments at heavy-ion storage rings. In particular, they can be used to accurately determine the masses and lifetimes of short-lived exotic nuclear species. [...]

Silicon strip sensors developed for the ATLAS Inner Tracker Upgrade have shown a strong dependence of the breakdown voltage on varying levels of relative humidity (RH). The solution to this humidity sensitivity has so far been to store and test the sensors in a dry environment (RH < 10 %). [...]

Ecto-5’-nucleotidase (CD73) is a potential new drug target for cancer immunotherapy. Its overexpression is associated with various aggressive cancers, including triple-negative breast cancer (TNBC) and pancreatic cancer, making it a promising target for diagnostic imaging. [...]
