Stick‐Slip Tremor Beneath an Alpine Glacier
Geophysical Research Letters, 2021 Sliding of glacial ice over its base is typically described by a frictionless or slowly deforming bed. This view is challenged by recent seismic observations of stick‐slip motion at the ice‐bed interface.

The Characteristics of Tremor Motion Help Identify Parkinson's Disease and Multiple System Atrophy
Frontiers in Neurology, 2020 Background/Objectives: Distinguishing between Parkinson's disease (PD) and multiple system atrophy (MSA) is challenging in the clinic because patients with these two conditions present with similar symptoms in motor dysfunction.

Tremor analysis with wearable sensors correlates with outcome after thalamic deep brain stimulation
Clinical Parkinsonism & Related Disorders, 2020 Introduction: Thalamic deep brain stimulation (DBS) provides excellent tremor control in most patients with essential tremor (ET). However, not all tremor patients show clinically significant improvement after DBS surgery. Currently, there is no reliable

Modeling source parameters of quasi-periodic tremor
Volcanica, 2020 Modeling harmonic tremor recorded at volcanoes is an essential practice in improving eruption forecasting methods and warning systems. We model the conduit dynamics of quasi-periodic tremor (chugging) recorded at Karymsky, Tungurahua, and Fuego volcanoes

Spectral analysis of harmonic tremor signals at Mt. Semeru Volcano, Indonesia [PDF]
Geophysical Research Letters, 1995 A detailed spectral analysis of tremor signals recorded at Mt. Semeru volcano, Indonesia, in October 1992 by the German‐Indonesian Volcano Expedition (GIVE'92) reveals clearly harmonic spectra containing up to 11 integer harmonics. The spectral features can be explained by any rhythmically pulsating source producing a temporarily stable source signal ...

Laryngoscope Investigative Otolaryngology, 2022 Objectives The success of type 2 thyroplasty (TP2) for adductor spasmodic dysphonia (AdSD) depends on the selection of optimally sized titanium bridges, which requires accurate assessment of intraoperative vocal changes.

Dynamics of the Askja caldera July 2014 landslide, Iceland, from seismic signal analysis: precursor, motion and aftermath [PDF]
Earth Surface Dynamics, 2018 Landslide hazard motivates the need for a deeper understanding of the events that occur before, during, and after catastrophic slope failures. Due to the destructive nature of such events, in situ observation is often difficult or impossible. Here, we

Journal of NeuroEngineering and Rehabilitation, 2021 Background Some people with Parkinson’s disease (PD) report poorer dynamic postural stability following high-frequency deep brain stimulation of the subthalamic nucleus (STN-DBS), which may contribute to an increased falls risk.

Tremor and its duration‐amplitude distribution at Popocatépetl volcano, Mexico
Geophysical Research Letters, 2016 The duration‐amplitude distribution was calculated for the tremor observed at Popocatépetl volcano during episodes of activity in 2000 and 2012–2014. An exponential function was used to obtain a good fit for the duration‐amplitude distribution, and the ...

Observations of two special kinds of tremor at Galeras volcano, Colombia(1989-1991)
Annals of Geophysics, 1999 Since the reactivation of Galeras volcano in 1988 its seismic activity has been dominated by a variety of LP waveforms and tremor events. Some of these signals occurred as a response to volcanic activity.
