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 ...

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Adaptive anomaly detection disruption prediction starting from first discharge on tokamak

Nuclear Fusion
Plasma disruption presents a significant challenge in tokamak fusion, especially in large-size devices like ITER, where it causes severe damage. While current data-driven machine learning methods perform well in disruption prediction, they require ...

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

Advanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy

Advanced Engineering Materials, EarlyView.
A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

The influence of electrode biasing on the up–down asymmetry of HFS-MSN divertor configuration in J-TEXT

Nuclear Fusion
The ${\mathbf{E}} \times {\mathbf{B}}$ drift is considered a key factor affecting particle and heat fluxes in the divertor. Recently, active modulation of the up–down asymmetry in high-field-side mid-plane single null (HFS-MSN) divertor configuration on ...
