What makes low-frequency earthquakes low frequency?
Science Advances, 2023 Low-frequency earthquakes are repetitive seismic events that occur downdip of the seismogenic megathrust where slow aseismic fault slip dominates the tectonic budget. These tiny events, distinct from regular earthquakes, have the potential to provide in-situ constraints on the fault rheology where slow slip occurs, but are hard to study due to their ...

Physical Therapy, 2006 Muscle fatigue has been defined as a temporary loss in force or torque-generating ability due to recent muscle contraction.1 The mechanisms underlying muscle fatigue are numerous and may have their origins anywhere from the central nervous system (CNS) to cellular-level cross-bridge cycling.2,3 The major proposed mechanisms of fatigue production are ...

Low-Frequency Noise: Experiences from a Low-Frequency Noise Perceiving Population
International Journal of Environmental Research and Public Health, 2023 Although low-frequency noise (LFN) is associated with various complaints, there is still much unknown about this phenomenon. This research aims to provide an extensive description of (1) LFN perceptions, (2) LFN-related complaints, and (3) the characteristics of LFN complainants. In an explorative observational cross-sectional survey study, a sample of

Physical Review Applied, 2022 Exquisite sensitivities are a prominent advantage of quantum sensors. Ramsey sequences allow precise measurement of direct current fields, while Hahn-echo-like sequences measure alternating current fields. However, the latter are restrained for use with high-frequency fields (above approximately $1$ kHz) due to finite coherence times, leaving less ...
