Motion‐Robust Multichannel sEMG Array for High‐Fidelity Muscle Fatigue Monitoring

ABSTRACT Real‐time muscle fatigue monitoring during dynamic activities is critical for preventing injury and optimizing performance, yet remains hindered by motion‐induced signal artifacts in conventional wearable systems. Here, we present a motion‐robust, multichannel surface el...

Dynamic modeling and simulation of supercritical carbon dioxide recompression Brayton cycle energy converter coupled with a 400MWth natural circulation lead-cooled reactor

The natural circulation lead-cooled fast reactor (NCLFR) possesses excellent neutron economy, thermal safety characteristics, and application potential. Meanwhile, the supercritical carbon dioxide recompression closed Brayton cycle (s-CO 2 -RCBC) has the merits of high thermal en...

Temperature Effects on Interfacial Area Concentration and Void Fraction in LBE-N2 Bubbly Flow

Temperature-dependent local two-phase flow parameters in lead–bismuth eutectic (LBE)–gas bubbly flows are essential for validating the closure models used in safety analyses of steam generator or heat exchanger tube rupture accidents in lead-cooled fast reactors. However, publish...

Synergistic Optimization of Reference Electrode and Solid Electrolyte for Bi/Bi2O3 Oxygen Sensors

The Bi/Bi2O3-type oxygen sensor is extensively employed for oxygen monitoring in liquid lead-bismuth eutectic (LBE)-cooled reactors, yet its low-temperature measurement accuracy remains a critical bottleneck limiting engineering deployment. This study aims to extend the lower ope...
