Seasonal Snow Cycles and Their Possible Influence on Seismic Velocity Changes and Eruptive Activity at Ruapehu Volcano, New Zealand

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 12, December 2024.
Abstract Understanding volcanic eruption triggers is critical toward anticipating future activity. While internal magma dynamics typically receive more attention, the influence of external processes remains less understood. In this context, we explore the relationship between seasonal snow cycles and eruptive activity at Ruapehu, New Zealand.

Small‐scale measurement of fracture toughness of muddy marine sediments via bubble injection

Limnology and Oceanography: Methods, Volume 22, Issue 8, Page 527-535, August 2024.
Abstract Muddy marine sediments are elastic materials in which bubbles grow and worms extend their burrows by fracture. Bubble growth and burrowing behavior are dependent on the stiffness and fracture toughness (KIc) of these muds. This article describes a custom laboratory apparatus to measure the fracture toughness of muddy, cohesive sediments using ...

A finely segmented semi‐monolithic detector tailored for high‐resolution PET

Medical Physics, Volume 51, Issue 5, Page 3421-3436, May 2024.
Abstract Background Preclinical research and organ‐dedicated applications use and require high (spatial‐)resolution positron emission tomography (PET) detectors to visualize small structures (early) and understand biological processes at a finer level of detail.

Timing performance evaluation of a dual-Axis rotational PET system according to NEMA NU 4-2008 standards: A simulation study

Biomedical Physics & Engineering Express
Abstract Introduction: Positron Emission Tomography (PET) imaging’s diagnostic accuracy is dependent on the scanner design and image quality, which is affected by several factors including the coincidence timing window (CTW).
