Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like

How Much Physics Should a Neural Network Know? Thermodynamics‐Informed Neural Networks for Rock Constitutive Modeling With Epistemic Uncertainty

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Machine learning offers a flexible route to constitutive modeling, with two emergent questions for geoscience applications: what level of thermodynamic constraint should be embedded in the network architecture, and how should predictive uncertainty be quantified when extrapolating from laboratory to field conditions? We address both challenges

Dissipated energy in undrained cyclic triaxial tests

open access: yes, 2015
Energy-based methods are an emerging tool for the evaluation of liquefaction potential. These methods relate excess pore water pressure build-up to seismic energy dissipated per unit volume. Further development of these methods require their validation through laboratory testing.

Identification of Activity, Insulin, and Dietary Thresholds Associated With Exercise‐Related Hypoglycaemia and Hyperglycaemia in Children With Type 1 Diabetes: A Free‐Living Study Using Explainable Machine Learning

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 10, Page 9505-9517, October 2026.
ABSTRACT Aims Some studies have explored associations between physical activity (PA) and hypoglycaemia in real‐life in type 1 diabetes (T1D) but without fully accounting for two major confounders, diet and insulin. We aimed to identify thresholds of PA characteristics, insulin, and carbohydrates associated with dysglycaemia across the exercise‐recovery

Infrared Thermographic Assessment of Fatigue Behavior in Bolted Composite Joints

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 10, Page 4136-4149, October 2026.
ABSTRACT This study investigates the temperature evolution of bolted thick glass fiber reinforced polymer composites during fatigue testing. Three different adherend thicknesses (8, 10, and 12 mm) and three different bolt tightening torques (30, 40, and 50 N ·m were considered to evaluate the effects of adherend thickness and bolt tightening torque on ...

Seismic and Aseismic Slip Compete to Regulate Permeability Evolution During Fault Reactivation

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Crustal permeability can be created through microearthquakes as observed at field and laboratory scales. The respective roles of seismic and aseismic slip in governing permeability evolution remain ill‐constrained. Here, we present observations of controlled pore pressure stepping experiments designed to distinguish the separate influences of ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Advanced Electron Microscopy and Microcomputed Tomography Analysis of Single‐Crystal Ni‐Base Superalloys After Short‐Term Multiaxial Creep

open access: yesAdvanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...

Wearable‐Derived Diurnal Alignment Between Physical Activity and Device Temperature Predicts Future Disease and Mortality Risk

open access: yesAdvanced Science, Volume 13, Issue 52, 18 September 2026.
Wearable‐derived diurnal alignment between physical activity and device temperature, decomposed into 24 h coupling strength (M24), phase deviation (D24), and 12 h harmonic magnitude (M12), is examined in approximately 90,000 UK Biobank participants.
