Array analysis of the seismic wavefield of long-period events and volcanic tremor at Arenal volcano, Costa Rica
(2014-06-06)
We use wavefield decomposition methods (time domain cross correlation and frequency domain multiple-signal classification) to analyze seismic data recorded by a dense, small-aperture array located 2 km West of Arenal ...
Objective measures of unobstructed walking and obstacle avoidance in Parkinson's disease subtypes
(Elsevier B.V., 2018-05-01)
Background: Objective measures of gait in Parkinson's disease (PD) patients according to motor subtypes are not yet fully understood. Although recent advances have been made for unobstructed walking, further work is required ...
On data reduction methods for volcanic tremor characterization: the 2012 eruption of Copahue volcano, Southern Andes
(Terra Scientific Publishing, 2020-12)
Improving the ability to detect and characterize long-duration volcanic tremor is crucial to understand the long-term dynamics and unrest of volcanic systems. We have applied data reduction methods (permutation entropy and ...
Is Cortical Activation during Walking Different between Parkinson's Disease Motor Subtypes?
(2021-04-01)
Parkinson's disease (PD) is often classified into tremor dominant (TD) and postural instability gait disorder (PIGD) subtypes. Degeneration of subcortical/cortical pathways is different betweenPD subtypes, which leads to ...
Postural control after unexpected external perturbation: Effects of Parkinson's disease subtype
(2019-04-01)
Different clinical subtypes of Parkinson's disease (PD) have long been recognized. Recent studies have focused on two PD subtypes: Postural Instability and Gait Difficulty (PIGD) and Tremor Dominant (TD). PIGD patients ...
Seismic responses to fluid pressure perturbations in a slipping fault
(American Geophysical Union, 2015)
Seismicity induced by fluid injection in a natural fault is investigated in situ in the near field of the source. We present synchronous seismic and hydromechanical measurements directly recorded in the decametric injection ...
