Integrating Eye Tracking and Inertial Sensing for Enhanced Freezing of Gait Detection in Parkinson's Disease

European Journal of Neuroscience, Volume 63, Issue 7, April 2026.
Wearable systems using inertial sensors can misclassify voluntary standing as freezing of gait (right). Adding eye‐gaze kinematics to a deep learning model reduces this error (left): standing misclassified as freezing decreases from 59.1% to 13.6%, standing recall more than doubles from 36.4% to 81.8%, and macro‐averaged F1 improves significantly from ...

Fractal Characteristics and Energy Evolution Analysis of Rocks under True Triaxial Unloading Conditions

Fractal and Fractional
To investigate the mechanical properties and energy evolution laws of rocks under true triaxial unloading conditions, a study was conducted using a true triaxial rock testing system on three different types of rocks: coal, sandy mudstone, and siltstone ...

Progressive damage and fracture behavior of brittle rock under multi-axial prestress constraint and cyclic impact load coupling

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
To explore the progressive damage and fracture mechanics characteristics of brittle rock materials under combined dynamic-static loading. Taking account of the coupling effect of the constraint states of uniaxial stress (σ 1 ≥ σ 2 = σ 3 = 0), biaxial ...

Stellar Streams as Probes of Dark Halo Mass and Morphology: A Bayesian Reconstruction

, 2011
Tidal streams provide a powerful tool by means of which the matter distribution of the dark matter halos of their host galaxies can be studied. However, the analysis is not straightforward because streams do not delineate orbits, and for most streams ...

Development and validation of three-way rigid true triaxial apparatus for soils

Yantu gongcheng xuebao
The intermediate principal stresses have a significant effect on the stress-strain behavior of soils. To describe the stress-strain behavior of soils more accurately, it is necessary to carry out true triaxial tests in the field of soil mechanics.
