A Deep Neural Network Based on Two‐Stage Training for Estimating Heart Rate Variability From Camera Videos

open access: yesHealth Care Science, Volume 5, Issue 1, Page 74-84, February 2026.
Heart Rate Variability Estimation from Camera Videos ABSTRACT Background Studies have shown that heart rate variability (HRV) is a predictor of the prognosis of cardiovascular diseases. Contact heartbeat monitoring equipment is widely used, especially in hospitals, and benefits from the rapidity and accuracy of the detection of physiological health ...

Bifurcation, Chaotic Behavior, Sensitivity Analysis, and Traveling Wave Solutions of the Nonlinear Telecommunication Model Through Transmission Lines

open access: yesDiscrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.
This paper explores a nonlinear telecommunication transmission line model with the incorporation of the M‐truncated fractional derivative, providing memory‐dependent effects that go beyond the classical nonlinear transmission line models. The Hamilton–Jacobi and Jacobian dynamical frameworks are, for the first time, utilized in this fractional ...

Towards aperiodic tesellation: a self-organising particle spring system approach [PDF]

open access: yes, 2008
The derivation of novel programming methods for the generation of aperiodic tiling patterns, predominantly in 2d space, has attracted considerable attention from both researchers and practicing architects.

Brain–Pupil Coupling Revealed Through Deep Learning of Intracranial Recordings

open access: yesHuman Brain Mapping, Volume 46, Issue 17, 01 December 2025.
Pupillary dynamics are closely linked to cognitive performance and band‐limited power in task‐relevant neural networks during attentional set‐shifting. Deep learning models based on intracranial neural recordings captured patterns predictive of changes in pupil size using a network of limbic, prefrontal and posterior regions.

The Dynamic Management of Working Memory Is Supported by Aperiodic Neural Activity

open access: yesPsychophysiology, Volume 62, Issue 9, September 2025.
ABSTRACT “Metacontrol” refers to the ability to achieve an adaptive balance between more persistent and more flexible cognitive‐control styles. Recent evidence from tasks focusing on the regulation of response conflict and of switching between tasks suggests a consistent relationship between aperiodic EEG activity and task conditions that are likely to

EEG Spectral Exponents and Visual Chirp Responses Mirror Anti‐Seizure Medication Load in Refractory Focal Epilepsy

open access: yesAnnals of Clinical and Translational Neurology, Volume 12, Issue 6, Page 1265-1275, June 2025.
ABSTRACT Objective Quantitative markers of cortical excitability may help identify responders to anti‐seizure medications (ASMs). We studied the relationship between ASM load and two electroencephalography (EEG) markers of cortical excitability in people with refractory epilepsy. Methods We included individuals with refractory focal epilepsy undergoing
