An optimizing microseismic method for rock burst early warning based on mining production process

open access: yesDeep Underground Science and Engineering, EarlyView.
A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.

Triboelectric–Electromagnetic Generator‐Enabled Hybrid Power Backpack for Self‐Powered Field Safety Management

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A lightweight hybrid backpack integrating SC‐TENGs and R‐EMGs harvests biomechanical energy during walking. With a low activation speed of 3 km h−1 and a high specific power of 0.18 W kg−1, it enables self‐powered field safety management. The power backpack refers to an energy‐harvesting solution engineered to mitigate battery reliance in wearable ...

Effectiveness and tolerability of fenfluramine in pediatric and adult patients with developmental and epileptic encephalopathies: A multicenter, retrospective, real‐world clinical‐practice study

open access: yesEpilepsia, EarlyView.
Abstract Objective Developmental and epileptic encephalopathies (DEEs) are characterized by drug‐resistant seizures and developmental slowing/regression. We examined the efficacy and tolerability of fenfluramine (FFA) in pediatric and adult patients with Lennox–Gastaut syndrome (LGS), Dravet syndrome (DS), and other DEEs.

Antiseizure potency and neurotoxicity of the enantiomers of fenfluramine and norfenfluramine in rats and correlations with their concentrations in plasma and brain

open access: yesEpilepsia, EarlyView.
Abstract Objective Based on the evidence that fenfluramine‐induced anorexia, weight loss, and cardiovascular toxicity are primarily mediated by the d‐enantiomers of fenfluramine and its metabolite norfenfluramine, we investigated pharmacokinetic/pharmacodynamic correlations for the active enantiomers of fenfluramine and norfenfluramine in the rat ...

Hybrid Inverters With Dual Switching Frequencies for Switched Reluctance Motors

open access: yesEnergy Science &Engineering, EarlyView.
A hybrid dual‐switching‐frequency inverter for SRMs is proposed, combining SiC and IGBT devices based on rotor inductance. The method enables accurate current tracking with simple hysteresis control, significantly reducing torque ripple, vibration, and acoustic noise while cutting inverter cost compared to full‐SiC solutions.
