TT4D: Tensor‐Train‐based 4D Time‐Dependent Volume Rendering

Computer Graphics Forum, EarlyView.
Abstract Visualizing large‐scale, time‐varying volumetric data using direct volume rendering remains a significant challenge in scientific visualization, particularly as data sizes and resolutions continue to increase. One promising direction for addressing this challenge is the use of tensor decompositions, which have proven to be a useful tool for ...

Network‐dependent remote effects and local tau burden jointly shape neuronal dysfunction in Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract BACKGROUND Tau pathology in Alzheimer's disease (AD) propagates along the brain's connectome, yet the mechanisms by which tau drives neuronal dysfunction remain unclear. We hypothesized that dysfunction primarily emerges in regions close to tau‐harboring epicenters. METHODS One hundred thirty‐one amyloid‐positive individuals underwent dynamic [

Design and simulation of dynamic voltage restorer (DVR) for power quality improvement

Journal of Physics: Conference Series, 2022
Abstract Power quality (PQ) is one of the main issues faced in the present era. The PQ issues such as voltage sags, swells, harmonics, and unbalance as well as the impact on sensitive loads are often occurred in any power distribution system. To tackle the issues, a powerful dynamic voltage restorer (DVR) is commonly installed.
