A Cortical Stress Signature of Fear‐Induced Walking: Mobile Electroencephalography Theta Suppression in Older Women With Fear of Falling

open access: yesPsychogeriatrics, Volume 26, Issue 6, November 2026.
ABSTRACT Background Fear of falling is one of the most common and disabling stress responses of later life, yet how it is expressed in the brain during real walking is poorly understood. We examined whether walking under a naturalistic psychological threat, a fear‐of‐falling stressor, changes cortical oscillatory activity in older women, using mobile ...

Local Generation of Plasmaspheric Plume Hiss

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The statistical analysis of hiss waves observed in the plasmaspheric plume (Wu et al., 2026, https://doi.org/10.1029/2026gl121667) is significant for identifying nonlinear wave growth processes in the equatorial region. Because nonlinear growth rates greatly exceed linear growth rates, they enable the local generation of new wave packets in ...

Curvature Classification for Trains using Along-Track and Cross-Track Accelerometer and a Heading Rate Gyroscope [PDF]

open access: yes, 2013
Real time curvature classification is crucial for all train localization problems. A reliable method to detected the track taken by the train after a switch is necessary and essential for train collision avoidance systems.

Opponent processes in human motion perception: shear and compression sensitivity, induced motion and motion capture [PDF]

open access: yes, 1994
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Sensitivity to differential motion components, shearing and compressive (opposed) motion, was examined. The hypothesis that the visual system contains local

The Evolution of Parallel Electric Field Across the Earth's Magnetosheath

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract In Earth's collisionless magnetosheath, turbulence evolution and energy transformation across the system, especially at kinetic scales, remain poorly quantified without full‐coverage of high‐resolution observations. Using multi‐traversal observations from the 2023 and 2024 Magnetospheric Multiscale (MMS) Unbiased Magnetosheath Campaign, we ...
