Upper Cervical Cord Area as a Biomarker of Conversion to Secondary Progressive Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study assessed whether upper cervical cord area (UCCA) measured on routine brain MRI can serve as a biomarker of conversion to SPMS. Methods This is a single‐center retrospective cohort study of RRMS patients with cross‐sectional and longitudinal analyses of clinical and MRI data. Future SPMS converters were matched by age, sex,

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.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Space-Vector Modulation Scheme for Three-Level Switched-Capacitor Boost Inverter With Constant Common-Mode Voltage

IEEE Access
The existing switched-capacitor quasi-switched boost inverter (SC-qSBI) has addressed neutral point voltage (NPV) unbalance issue. However, the common-mode voltage (CMV) of this topology is too high which causes high leakage current through parasitic ...

Tunable Complementary Doping Strategy Enables High‐Performance Homo‐Channel CMOS in Monolayer WSe2

Advanced Functional Materials, EarlyView.
Polarity‐selective modulation enables a homo‐channel WSe2 CMOS platform from a single 2D semiconductor. MoOx and AlN tune WSe2 toward p‐ and n‐type operation, respectively, yielding complementary FETs and inverters with balanced switching, high voltage gain, low static power, and promising scalability for 2D logic integration.
