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.

Proteomic signatures of equine dental tooth tissues in ageing and disease
Equine Veterinary Journal, EarlyView.Abstract Background Ageing and dental disease in horses lead to structural and functional deterioration of dental tissues, yet their molecular signatures remain poorly characterised. Understanding how these processes alter the protein composition of enamel, dentin, cementum and pulp is essential for improving equine oral health and identifying ...

Bacteremia in horses undergoing routine dental prophylaxis: Before, during, and after the procedure
Equine Veterinary Journal, EarlyView.Abstract Background Transient bacteremia after dental procedures is well‐documented in the literature, but the prevalence and clinical significance in horses remains largely unexplored. Objectives To assess whether routine dental prophylaxis in clinically healthy horses is associated with detection of bacteria in blood, using culture and 16S rDNA ...

Mining Oral Probiotics Based on Their Pathogen Inhibition and Deodorization Roles
Food Bioengineering, EarlyView.A promising oral probiotic strain Streptococcus salivarius MY‐6 stood out from 41 candidate lactic acid bacteria through the high‐throughput strategy based on its inhibitions of the growth and biofilm formation of the main oral pathogens Fusobacterium nucleatum and Porphyromonas gingivalis, as well as its elimination of oral malodor‐associated ...

Head &Neck, EarlyView.ABSTRACT Background Near‐infrared (NIR) fluorescence‐guided surgery using EGFR‐targeted tracers (e.g., panitumumab‐IRDye800CW) can provide real‐time visualization of tumors and margins in Head and Neck Squamous Cell Carcinoma. Prior studies have demonstrated its safety and potential to improve intraoperative decision‐making and margin assessment ...

Interdisciplinary Medicine, EarlyView.Here, we present a tetrahedral DNA framework (TDF)‐mediated Cas12a ordered assembly strategy. TDFs arrange CRISPR/Cas12a into ordered structures controllably, enhancing catalytic efficiency through localized Cas12a hotspots while maintaining spatial intervals to facilitate substrate diffusion.
