Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Formation mechanism of macrosegregation in dissimilar-filler welding of aluminum alloys

Journal of Materials Research and Technology, 2022
Dissimilar-filler welding is widely used for joining aluminum components. However, macrosegregation that will degrade the performance of the weld joint commonly occurs within the weld metal, because of the compositional difference between the filler and ...

Metal/metal oxides/silsesquioxanes as fillers for functional polymer composites

BME Horizon, 2023
Integration of inorganic fillers with polymer matrices opens up exciting possibilities for creating high-performance functional materials. Metal/metal oxides/silsesquioxanes as nanofillers are gaining attention for enhancing polymer matrices. Understanding the dispersion and interaction of these nanofillers is crucial for modifying properties in ...

What Do Large Language Models Know About Materials?

Advanced Engineering Materials, EarlyView.
If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...
