Impact of 2025 ASE Update Recommendations for the Evaluation of Left Ventricular Diastolic Function in Patients With End‐Stage Renal Disease

Yunxiang Miao, Wenwen Chen, Yuping Liao, Yao Yao et autres

BACKGROUND: Left ventricular diastolic dysfunction (LVDD) is highly prevalent in end-stage renal disease (ESRD) but remains difficult to assess accurately. The 2025 American Society of Echocardiography (ASE) update has introduced left atrial reservoir strain (LARS) as a novel parameter for estimating left …

CDFIT: A Transformer Using Cross-Modal Dual-Stream Feature Interaction for Multispectral Pedestrian Detection

Zihao Huang, Wenshi Li, Yuzhen Zhang, Jiaren Guo et autres

Modality imbalance is a significant challenge for multi-modal interaction at various depths in multispectral pedestrian detection under varying illumination environments. To overcome the limitations of current cross attention in addressing the modality imbalance, we propose the Cross-Modal Dual-Stream Feature Interaction Transformer (CDFIT). …
