A Passive Low‐Frequency, High‐Sensitivity Diamagnetic Levitation Accelerometer
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Despite the great potential of diamagnetic levitation accelerometers in detecting low‐frequency and weak motion, there is still a demand to further enhance their sensitivity for geophysical and microgravity applications. In this study, a straightforward structural modulating approach is presented to enhance the sensitivity of diamagnetic ...

Stray Light Analysis and Mitigation Perspectives for Next Generation Gravitational-Wave Detectors
GalaxiesThe low-frequency sensitivity of gravitational-wave detectors can be degraded by noise arising from the re-coupling of stray light with the main interferometer beam. This review describes the re-coupling mechanism and shows how the experience gained with

Permafrost and Periglacial Processes, EarlyView.ABSTRACT The progressive weakening of alpine rockwalls through subcritical cracking, driven by repeated low‐magnitude stress processes, plays a key role in alpine rock weathering. Laboratory studies using acoustic emission (AE) monitoring have shown that thermal stresses from freeze–thaw cycling induce crack propagation, with recent work highlighting ...

Permafrost and Periglacial Processes, EarlyView.ABSTRACT The existence of permafrost was explored at tropical latitude on Nevado Coropuna (southern Peruvian Andes) using a combination of ground‐penetrating radar (GPR) and vertical electrical sounding (VES) in order to strengthen the mutual validation of data processing and interpretation.

Near‐resonant excitation of the Adriatic barotropic modes: The seiche events of December 2019
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study examines severe flooding in the northern Adriatic Sea in December 2019, which existing forecasting systems failed to predict. Analysis of wind and sea‐level data, alongside reanalysis datasets and a high‐resolution hydrodynamic model, revealed a wind‐induced resonance mechanism.
