3月3日，上海交通大学等单位在《自然·生物医学工程》（Nature Biomedical Engineering）发表论文An ophthalmic video foundation model for surgical recognition and navigation with wet-lab porcine eye validation，报告他们研发了一款专为眼科显微手术的识别和导航而设计的视频基础模型（OVFM）。其采用自监督视觉变换器架构，在包含144种手术类型、110万段视频片段的眼科视频数据集上完成训练，习得眼科手术的时空运动特征。研究团队采用知识蒸馏技术，在保持模型精度的同时缩减模型规模，使其可部署于手术显微镜设备。在十位外科医生开展的猪眼白内障手术中，使用OVFM能有效缩小医师间的技术差距。

Angharad Saunders says she will struggle to find a place to park once the restrictions come into place
This time around, Liverpool made no mistake at Molineux. They stayed on the road to Wembley, thanks to two players signed in 2017, beloved veterans with uncertain futures. Andy Robertson and Mohamed Salah scored the goals to ease the pain of Tuesday’s Premier League defeat before Curtis Jones’s strike completed a night of relative comfort. Wolves crashed back to the reality of eight remaining top-flight matches before the drop. Their goal from Hwang Hee-chan came far too late.
