Infrasound Detection Using Polymer Networks in Liquid Films [PDF]
IEEE Sensor Letters 8 (5), 1-4 (2024)Recording and analyzing infrasound signals is essential to study natural phenomena, such as earthquakes, weather, or avalanches, but also has practical importance in aviation industry, optimization of wind turbines, and many more. However, the detection of faint infrasound signals is still a significant challenge as the transducers (e.g., mechanical ...

Ultrasound fundamentals and their clinical implications for interventional cytopathologists
Cytopathology, EarlyView.Interventional cytopathologists need to know about ultrasound physics and instrumentation to produce an image that faithfully recreates the lesion discovered by the sonographer and diagnosed by the radiologist. A deep quantitative understanding of physics is not required.

UAS‐Based Observations of Infrasound Directionality at Stromboli Volcano, Italy
Geophysical Research Letters, 2023 Infrasound (low frequency sound waves) can be used to monitor and characterize volcanic eruptions. However, infrasound sensors are usually placed on the ground, thus providing a limited sampling of the acoustic radiation pattern that can bias source size

Inferring Eruption Dynamics From Seismometer Tilt: A Case Study of Erebus and Augustine Volcanoes
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.Abstract Broadband seismometers are sensitive to tilt as a consequence of their design. We used broadband data from Erebus volcano on Ross Island, Antarctica, and Augustine volcano in Lower Cook Inlet, Alaska, to make tilt measurements associated with individual volcanic explosions and investigate the near‐terminal magmatic system configuration of each

Uncertainty Reduction for Subaerial Landslide‐Tsunami Hazards
Journal of Geophysical Research: Earth Surface, Volume 130, Issue 4, April 2025.Abstract Subaerial rock slopes may generate a tsunami by rapidly moving into the water. Large uncertainty in landslide characteristics propagates into large uncertainty in tsunami hazard, making hazard assessment more difficult for land and emergency managers.
