Epilepsia, EarlyView.Abstract Objective Using a Dutch insurance claims registry, we examine whether people with epilepsy have an increased risk of major ischemic cardiovascular events or death compared to people without epilepsy. We also assess whether this risk differs between users of enzyme‐modulating and non‐enzyme‐modulating antiseizure medications (ASMs).

Hybrid Inverters With Dual Switching Frequencies for Switched Reluctance Motors
Energy 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.
