Hybrid machine learning models for enhanced arrhythmia detection from ECG signals using autoencoder and convolution features.

PloS one
Automated arrhythmia detection from electrocardiogram (ECG) signals is crucial and important for the early treatment of cardiac disease (CD). In this investigation, eight machine-learning models have been developed to identify improved ECG arrhythmia...

Interpretable Yield Prediction of Supercritical CO Extraction from Various Essential Oil Sources Using Optimized Machine Learning and PCA-Based Descriptors.

Journal of chemical information and modeling
Predicting essential oil yield in supercritical CO (SC-CO) extraction remains difficult due to variations in plant composition and process conditions. Conventional models often assume uniform feedstock behavior, which limits their applicability acros...

A Hybrid OPES-eABF Framework for Efficient Exploration and Data-Driven Collective Variable Discovery in Complex Free-Energy Landscapes.

Journal of chemical information and modeling
Molecular dynamics (MD) simulations are powerful tools for studying biomolecular systems, but they are fundamentally limited by accessible time scales, making the study of rare events such as protein folding or ligand unbinding computationally challe...

Multiobjective Optimization of Metal-Organic Framework Structural Properties and Synthesis Costs through Machine Learning.

Journal of chemical information and modeling
Metal-organic frameworks (MOFs) are a novel class of porous materials characterized by high surface area, high porosity, and tunable structure, possessing immense application potential. Many synthesis methods have been developed for MOFs, such as che...

The alternative splicing landscape of hepatocellular carcinoma and its potential for HCC detection.

Hepatology communications
BACKGROUND: Pre-mRNA alternative splicing contributes to oncogenic gene expression in hepatocellular carcinoma (HCC), and some oncogenic isoforms escape the tumor into circulation. This study aimed to characterize the alternative splicing landscape o...

Orthogonal Biochemical Sensing for Concentration-Independent Bacterial Fingerprinting.

Analytical chemistry
Array-based biosensors hold substantial promise for rapid bacterial identification. However, conventional approaches face two key limitations: their reliance on nonspecific interactions with bacterial surfaces hinders biochemical interpretation, and ...

Development and validation of a predictive model for postoperative acute respiratory distress syndrome in patients with type A aortic dissection based on the 2023 updated definition.

Respiratory research
BACKGROUND: Acute respiratory distress syndrome (ARDS) is a common complication after type A aortic dissection surgery and often leads to worsened clinical outcomes for patients. The early prediction of postoperative ARDS is a crucial challenge in cl...

Artificial Intelligence in Ocular Drug Delivery: Precision Drug Delivery's New Horizon.

AAPS PharmSciTech
BACKGROUND: Artificial intelligence is emerging as a transformative force in pharmaceutical sciences by enabling data-driven decision-making, automation, and predictive modeling. In ocular drug delivery, where therapeutic efficacy is hindered by comp...

Explainable machine learning to predict prolonged post-operative opioid use in rotator cuff patients.

BMC musculoskeletal disorders
BACKGROUND: Opioid overuse is a costly and significant problem in the United States. Medical specialties including surgery are a contributor to opioid prescriptions while having few clear prescribing guidelines. Machine learning predictive tools can ...

Feature learning augmented with sampling and heuristics (FLASH) improves model performance and biomarker identification.

NPJ systems biology and applications
Big biological datasets, such as gene expression profiles, often contain redundant features that degrade model performance and limit generalization across independent datasets with complexities like class imbalance and hidden sub-clusters. To overcom...
