No Evidence of Phase-Amplitude Coupling in Auditory Steady-State Responses

IEEE Transactions on Neural Systems and Rehabilitation Engineering
Phase-amplitude coupling (PAC), reflecting the modulation of high-frequency amplitude by the phase of lower-frequency oscillations, is increasingly recognized as a key mechanism underlying neural information processing.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Decoding stress resilience: The role of heart rate variability and cross-frequency coupling during mental arithmetic stress

NeuroImage
Stress triggers various physiological and neural responses, but phase-amplitude coupling (PAC) in the brain under stress remains underexplored. This study computed modulation indices (MIs) to quantify PAC between theta-alpha (4–13 Hz) and low-gamma (LG ...

Variable Stiffness Flexure Structures Enabled by Phase‐Change Gallium and Adhesive Interfacial Locking for Soft Robotic Applications

Advanced Engineering Materials, EarlyView.
A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing
