Respiratory sinus arrhythmia in diabetic neuropathy [PDF]

open access: yesDiabetologia, 1983
Heart rate variation was measured at different rates of regular deep breathing (2.5 to 13 breaths/min) in 11 normal subjects and 13 diabetic patients with neuropathy, defined clinically by the absence of both ankle jerks or the presence of autonomic symptoms. Subjects were divided into those above and below 30 years old.

Accelerating virtual patient generation with a Bayesian optimization and machine learning surrogate model

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 486-494, March 2025.
Abstract The pharmaceutical industry has increasingly adopted model‐informed drug discovery and development (MID3) to enhance productivity in drug discovery and development. Quantitative systems pharmacology (QSP), which integrates drug action mechanisms and disease complexities to predict clinical endpoints and biomarkers is central to MID3.

ECG‐TransCovNet: A hybrid transformer model for accurate arrhythmia detection using Electrocardiogram signals

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
Abstract Abnormalities in the heart's rhythm, known as arrhythmias, pose a significant threat to global health, often leading to severe cardiac conditions and sudden cardiac deaths. Therefore, early and accurate detection of arrhythmias is crucial for timely intervention and potentially life‐saving treatment.
