Adaptive Calculation Method of Line Loss of Distribution Network Based on Genetic Algorithm and Artificial Neural Network

Engineering Reports, Volume 8, Issue 4, April 2026.
A GA‐BP neural network model with optimized preprocessing and clustering reduces line loss calculation errors and improves efficiency in distribution networks. ABSTRACT Traditional methods for calculating distribution line losses often rely on complex mathematical models and extensive operational data, leading to cumbersome processes that struggle to ...

Generalized Additive Model With Dynamic Coefficients for Spatiotemporal Ozone Predictions

Environmetrics, Volume 37, Issue 3, April 2026.
ABSTRACT Accurate prediction of surface‐level ozone concentrations is critical for air quality management and public health protection. This study develops a flexible spatiotemporal statistical modeling framework to predict daily mean O3 concentrations across Italy by integrating satellite‐derived ozone estimates with ground‐based observations and high‐

Underweight Status Amplifies Respiratory Infection Mortality in Diabetes: Findings From a Nationwide Cohort Study

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 2, April 2026.
ABSTRACT Background Diabetes increases susceptibility to infectious respiratory diseases, but the impact of underweight status on mortality from these conditions remains unclear. We evaluated the association between low body mass index (BMI) and respiratory infection‐related mortality in a large nationwide cohort of individuals with diabetes.

Contact Index–Guided Pulsed Field Ablation: A Two‐Phase Validation of the Impedance Change Threshold to Prevent Acute Pulmonary Vein Gaps

Journal of Arrhythmia, Volume 42, Issue 2, April 2026.
This two‐phase study demonstrates that a Contact Index impedance change of ≥ 10% reliably indicates adequate catheter contact during pulsed field ablation (PFA). Enforcing this threshold significantly reduced acute pulmonary vein gaps (PVGs) without prolonging procedure or fluoroscopy times.

Large Deformation Pile‐soil Interaction Under Lateral Vehicle Impact Using Hybrid SPH+FEM and EFG+FEM Models

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 5, Page 2648-2669, 10 April 2026.
ABSTRACT This study presents large deformation computational methods to simulate lateral vehicular impacts on steel piles in granular soil. Soil‐mounted longitudinal barrier systems rely on energy dissipation in both the piles and the surrounding soil to safely redirect errant vehicles, so dynamic pile‐soil interaction is important for design ...

Improving Population Pharmacokinetic Modelling with Artificial Patients using Generative Artificial Intelligence

Pharmacology Research &Perspectives, Volume 14, Issue 2, April 2026.
ABSTRACT In population pharmacokinetics (PopPK), non‐linear mixed effects (NLME) models are used to simultaneously describe a drug's pharmacokinetics (PK) and dynamics (PD) in a patient population using systems of ordinary differential equations. In this field, machine learning is mainly used for data preparation, hypothesis generation, predictive ...

Flexible yet Sparse Bayesian Survival Models With Time‐Varying Coefficients and Unobserved Heterogeneity

Statistics in Medicine, Volume 45, Issue 8-9, April 2026.
ABSTRACT Survival analysis is an important area of medical research, yet existing models often struggle to balance simplicity with flexibility. Simple models require minimal adjustments but come with strong assumptions, while more flexible models require significant input and tuning from researchers.
