The Global Wheat Head detection(GWHd)dataset was created in 2020 and has assembled 193,634 labelled wheat heads from 4700 RGB images acquired from various acquisition platforms and 7 countries/*** an associated competition hosted in Kaggle,GWHd_2020 has successfully attracted attention from both the computer vision and agricultural science *** this first experience,a few avenues for improvements have been identified regarding data size,head diversity,and label *** address these issues,the 2020 dataset has been reexamined,relabeled,and complemented by adding 1722 images from 5 additional countries,allowing for 81,553 additional wheat *** now release in 2021 a new version of the Global Wheat Head detection dataset,which is bigger,more diverse,and less noisy than the GWHd_2020 version.

尽管脑血管病的影响广泛且对其病理生理学的理解已取得一些进展，但“卒中”一词在临床实践、临床研究和公共卫生评价中的定义并不统一。经典的卒中定义主要是临床定义，不能反映科学技术的进步。因此，美国心脏协会卒中委员会／美国卒中协会召集了一个写作组，旨在对21世纪的卒中新定义制定一份专家共识文件。中枢神经系统（centralnervoussystem，CNS）梗死被定义为缺血导致的脑、脊髓或视网膜细胞死亡，并且具有永久性损伤的神经病理学、神经影像学和（或）临床证据。CNS梗死具有一系列临床表现：缺血性卒中特指伴有明显症状的CNS梗死，而无症状梗死则顾名思义不引起明显症状。广义的卒中还包括脑出血和蛛网膜下腔出血。卒中的新定义结合了临床和组织学标准，因此能被融入临床实践、研究和公共卫生评价。
