Suppression of sawtooth oscillations by m/n = 2/2 resonant magnetic perturbation

Nuclear Fusion
Significant extension of sawtooth control toward higher electron density ( n _e ) and edge safety factor ( q _a ) ranges has been achieved by m / n = 2/2 resonant magnetic perturbation (RMP), which is ∼8 times stronger than the previous RMP generated by ...

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

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Flexural Behavior of 3D‐Printed Porous Bouligand‐Structured Polymers: Influence of Pitch Angle and Porosity

Advanced Engineering Materials, EarlyView.
This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight

Impact of low-Z impurity injection on the post-disruption runaway electron current in the J-TEXT tokamak

Nuclear Fusion
Major disruptions in tokamak plasmas pose a severe threat to the safe and stable operation of the device, and the runaway current formed by high-energy runaway electrons is one of the hazardous consequences. Massive impurity injection serves as a primary
