Reconstructing the arrival direction of neutrinos in deep in-ice radio detectors

European Physical Journal C: Particles and Fields, 2023
In-ice radio detectors are a promising tool for the discovery of EeV neutrinos. For astrophysics, the implications of such a discovery will rely on the reconstruction of the neutrino arrival direction.

X-ray Dark-Field Imaging for Improved Contrast in Historical Handwritten Literature

Journal of Imaging, 2022
If ancient documents are too fragile to be opened, X-ray imaging can be used to recover the content non-destructively. As an extension to conventional attenuation imaging, dark-field imaging provides access to microscopic structural object information ...

Evaluation of the Weighted Mean X-ray Energy for an Imaging System Via Propagation-Based Phase-Contrast Imaging

Journal of Imaging, 2020
For imaging events of extremely short duration, like shock waves or explosions, it is necessary to be able to image the object with a single-shot exposure. A suitable setup is given by a laser-induced X-ray source such as the one that can be found at GSI

Microstructure evolution of AZ91 alloy processed by a combination method of equal channel angular pressing and rolling

Journal of Magnesium and Alloys, 2020
In the present work, AZ91 alloy was successfully processed by equal channel angular pressing (ECAP) for up to 16 passes and rolling (R) for multiple passes with a total reduction of 75% in addition to a combination method with ECAP plus rolling (ECAP+R).

Complaints and Diagnoses of Emergency Department Patients in the Netherlands: A Comparative Study of Integrated Primary and Emergency Care. [PDF]

PLoS ONE, 2015
In the Netherlands, an increasing number of emergency departments (EDs) and general practitioner cooperatives collaborate by creating one Emergency-Care-Access-Point (ECAP). This has resulted in fewer patients at ECAP EDs. The objective of this study was

Effect of ECAP process on mechanical properties and microstructure of AA-6061 recycled chips [PDF]

Engineering and Technology Journal, 2023
The oxidation of aluminum machined chips makes successful recycling via the traditional re-melting technique difficult. A viable solution to this problem is to utilize solid-state recycling to transform aluminum machined chips directly into semi-finished
