Sensors, 2022 Atrial fibrillation (AF) is the most common clinically significant arrhythmia; therefore, AF detection is crucial. Here, we propose a novel feature extraction method to improve AF detection performance using a ballistocardiogram (BCG), which is a weak ...

Machine learning for forecasting initial seizure onset in neonatal hypoxic-ischemic encephalopathy. [PDF]
EpilepsiaAbstract Objective This study was undertaken to develop a machine learning (ML) model to forecast initial seizure onset in neonatal hypoxic–ischemic encephalopathy (HIE) utilizing clinical and quantitative electroencephalogram (QEEG) features. Methods We developed a gradient boosting ML model (Neo‐GB) that utilizes clinical features and QEEG to ...

Recurrence Quantification Analysis of F-Waves and the Evaluation of Neuropathies
Neurology Research International, 2015 Electrodiagnostic (EDX) patterns of neuropathic dysfunction have been based on axonal/demyelinating criteria requiring prior assumptions. This has not produced classifications of desired sensitivity or specificity.

Team Cognition Research Is Transforming Cognitive Science
Topics in Cognitive Science, EarlyView.Abstract About 30 years ago, the Dynamical Hypothesis instigated a variety of insights and transformations in cognitive science. One of them was the simple observation that, quite unlike trial‐based tasks in a laboratory, natural ecologically valid behaviors almost never have context‐free starting points.

Recurrence quantification analysis of heart rate variability to detect both ventilatory thresholds.
PLoS ONE, 2021 Aims of this study were: to verify if Recurrence Quantification Analysis (RQA) of Heart Rate Variability (HRV) time series could determine both ventilatory thresholds in individuals with different fitness levels, and to assess the validity of RQA method ...

The 3‐Hit Metabolic Signaling Model for Autism Spectrum Disorder: A Summary
Autism Research, Volume 19, Issue 5, May 2026.ABSTRACT Autism spectrum disorder (ASD) is a highly heritable yet environmentally sensitive neurodevelopmental condition whose biological heterogeneity has resisted a unifying causal explanation for over 100 years. The 3‐hit metabolic signaling model proposes that ASD arises from abnormal persistence of an evolutionarily conserved stress‐response ...
