Core Insights - A new algorithm developed by a team from Shanghai's Tenth People's Hospital can accurately identify ST-segment elevation myocardial infarction (STEMI) patients through standard 12-lead electrocardiograms (ECGs), potentially reducing mortality rates and the risk of sudden cardiac death [1][3][4] - The success rate of treating acute myocardial infarction is highly time-dependent, with a significant difference in mortality rates between patients receiving rapid treatment and those experiencing delays [3] - The integration of artificial intelligence (AI) in analyzing ECG waveforms is expected to optimize emergency decision-making and improve patient outcomes [3][4] Technology Development - The research team has developed a wearable 12-lead ECG vest, which has received national Class II medical registration and is now in mass production [4] - The vest automatically transmits ECG signals to the cloud, where software can provide alerts for myocardial infarction and malignant arrhythmias [4] - The team has compiled over 10,000 preoperative ECG data samples and is expanding its dataset to enhance the AI's ability to identify and locate myocardial infarction [4] Future Implications - The AI-driven ECG system aims to provide efficient early warnings for high-risk groups and postoperative patients, potentially lowering the incidence of myocardial infarction and sudden cardiac death [4] - The system may also enhance the capabilities of emergency departments and chest pain centers in identifying acute myocardial infarction, thereby improving patient prognosis [4]
小流域治理也不能忘了防洪
小流域综合治理是一项综合性、系统性的工程,作为其中的关键组成部分,汛期防洪工作不仅关系到人 民群众生命财产的安全,也直接影响整个治理项目的成效与长期运行的稳定性。因此,在推进小流域综 合治理的过程中,必须将汛期防洪纳入整体规划,并在实施过程中予以高度重视和科学部署。 当前正值汛期,很多地方的防洪任务艰巨。但也有个别地方在小流域综合治理中忽视汛期防洪工作,不 仅不认真开展流域生态环境修复,不建设防范山洪灾害的工程设施 ,还因其他主客观原因,随意改变 河道形状及水流状态,甚至在河道上、急流处建设影响泄洪的旅游设施,导致存在很多安全隐患,给当 地防洪工作造成不利影响。 由于小流域往往地形起伏较大、地表覆盖不均,降雨后汇流速度快,极易在短时间内形成较大的径流 量,进而引发山洪、泥石流等突发性灾害。因此,在小流域综合治理过程中,应充分结合流域内的自然 地理特征和历史水文资料,因地制宜布设排水沟渠、拦洪堤坝、导流渠等防洪排涝设施,构建起结构合 理、功能完备的防洪工程体系。例如,在城镇等沿岸重要保护目标附近,修建淤地坝、沉沙塘等设施, 拦截山洪泥沙,稳固河床,避免泥沙大量涌入城镇建成区。同时,还应加快建立和完善雨情、水情、 ...

天文学家发现第三个进入太阳系的“星际访客”
Guan Cha Zhe Wang· 2025-07-04 03:02
【文/观察者网 陈思佳】据美国有线电视新闻网(CNN)7月3日报道,天文学家近日证实,一个来自星 际空间的天体3I/ATLAS已经进入太阳系,预计它将在今年晚些时候从火星附近掠过,最终飞出太阳 系。这是迄今为止人类发现的第三个进入太阳系的星际天体。 当地时间1日,位于智利里奥乌尔塔多、由美国国家航空航天局(NASA)资助的小行星撞击地球最后 预警系统(ATLAS)望远镜首次报告发现一颗来自星际空间的彗星,它来自人马座方向,最初被标记 为物体A11pl3Z,现已被正式命名为3I/ATLAS和C/2025 N1。 NASA称,研究人员随即查阅了全球三台ATLAS望远镜和加利福尼亚州帕洛玛山天文台兹威基瞬变观测 设施的档案,追溯到6月14日的观测数据。对彗星运动轨迹的计算表明,这颗天体来自太阳系以外。 NASA喷气推进实验室近地天体研究中心主任保罗·乔达斯(Paul Chodas)表示:"当我们追溯它的轨 迹,我们发现它显然起源于太阳系之外。它肯定来自另一个恒星系统,并且可能已在星际空间中飞行了 数百万年,直到它偶然造访我们的太阳系。" 意大利虚拟望远镜项目捕捉到的3I/ATLAS图像 虚拟望远镜项目网站 目前,天 ...
