Aging of Tetrafluoroethylene Propylene (FEPM) Material in High‐Pressure HighTemperature Hydrogen Sulfide Downhole Environment: Theory, Modeling, Experiments, and Material Lifetime Prediction

open access: yesMacromolecular Theory and Simulations, Volume 35, Issue 1, January 2026.
A novel approach that integrates AI‐based methodology, laboratory experimentation, and field application experience to accurately predict the lifespan of elastomeric materials in harsh downhole environments. ABSTRACT This paper presents a physics‐driven neural network (PINN) model to capture the constitutive behavior, elongation at break (EAB), modulus,

A Probabilistic Cut Finite Element Method With Random Field Generator and Bayesian Model Calibration for Flow Through Rough Cracks

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 1, Page 298-320, January 2026.
ABSTRACT A new model for the simulation of fluid flow through rough cracks is presented. The model combines a probabilistic cut finite element method (PCutFEM) to capture the unfitted boundary condition at the fluid interface, with a stochastic random field generator to represent the crack asperities.

Fluorescent Imaging in Thyroid Surgery to Preserve Parathyroid Function: A Systematic Review and Meta‐Analysis

open access: yesOtolaryngology–Head and Neck Surgery, Volume 174, Issue 1, Page 30-44, January 2026.
Abstract Objective Hypoparathyroidism and postoperative hypocalcemia are rare but dreaded complications of thyroid surgery, often requiring increased follow‐up and contributing to financial and quality‐of‐life burdens. This systematic review evaluates the effectiveness of intraoperative fluorescent imaging of parathyroid glands (PGs) in improving PG ...

Global Resource Disparities Between Pulmonary Hypertension Centers: Results From the International Survey by the PVRI IDDI Access to Care Workstream

open access: yesPulmonary Circulation, Volume 16, Issue 1, January 2026.
ABSTRACT There is a limited understanding of how pulmonary hypertension (PH) patients are managed worldwide. The Pulmonary Vascular Research Institute (PVRI) Innovative Drug Discovery Initiative (IDDI) global survey attempted to obtain insights into access to PH care in diverse international regions to pave future action plans.

Analysis of Methyl Substitution in Phenolic Compounds as Potential Biofuel Additives: From Solid‐State Description to Antioxidant Potential

open access: yesChemistrySelect, Volume 11, Issue 2, 15 January 2026.
The rising demand for renewable energy points to biodiesel as a viable fossil fuel alternative, yet its limited oxidative stability remains a challenge. This study reveals that methyl‐substituted hydroquinone derivatives exhibit enhanced antioxidant capacity, suggesting their promise as biofuel additives.
