据悉，后续，阿里达摩院将联合浙大一院在全国范围内推广iAorta模型。 （文章来源：新华财经） 据介绍，iAorta是阿里达摩院基于在"平扫CT+AI"方面的领先技术，联合浙江大学医学院附属第一医院 （下简称"浙大一院"）历时三年多研发出的AI模型，攻克了急性主动脉综合征（AAS）的漏诊、误诊频 发的国际难题。在20万人的大规模临床试验中，iAorta模型的敏感性和特异性分别达到95.5%和99.4%， 可将AAS的漏诊率从48.8%显著降低至4.8%，平均确诊时间从4.3小时缩短至1.7小时。 相关专家表示，该AI模型所需检查手段仅为常规平扫CT，偏远地区和基层医院无需额外采购设备即可 部署，具有重大的医疗普惠意义。 新华财经北京12月15日电 记者从阿里获悉，近日，工业和信息化部、国家药品监督管理局联合组织的 2025年人工智能医疗器械创新任务揭榜挂帅入围单位公布，阿里达摩院牵头研发的"急性主动脉综合征 CT图像智能辅助分诊软件"iAorta成功入选。该AI模型已在全国十余家医院落地，帮助减少急性主动脉 综合征的漏诊、误诊。 ...

12月15日，今天A股表现较弱，下方支撑依然是120日均线。有人担心股市复刻2015-2016的走势，我认为这是"杞人忧天"，属于"刻舟求剑"的谬误观点。 这一轮牛市上涨的核心逻辑是中国资产的价值重估，DeepSeek让世界认识到了中国企业的研发实力强大。中国有世界一流的科技企业，却有第三世界国家 的估值水平，投资人要对中国经济和股市有信心，要坚定看多唱多，不仅是保持正能量、乐观的心态，而是要相信中国必将在未来成为世界经济的领军力 量。 若能坚定以上信念，那么本轮牛市中的每一波下跌，都将是我们的财富机遇。 若确信中国经济和股市将在未来十年或者二十年蒸蒸日上，那么我们可以采取一种匹配该预期的投资方式。择股和择时我说很多遍了。 那么今天，我来谈一种基于仓位管理的投资策略。做法很简单，我称之为"半仓持股法"。即永远持有半仓。比如你用50%的现金买入A股票，同时保留50% 的现金。若A股票下跌下跌20%，此时你A股市值和现金比重为4:6（非严谨计算），那么此时你可以拿出现金，重新让市值和现金的比例回到1:1。 这个持仓配置非常适合那些：长期经营稳定，但短期来看，企业股价波动率较大的股票。 该投资策略来自计算机之父香农 ...

千问把PPT制作、写作润色、翻译、拍题答疑和资料检索等高频需求以免费方式提供，被不少学生 视为"把好几个会员合在一起"。也有用户在小红书评论称，省下的订阅费用"算下来够一台iPad了"。 大学生对千问的用法各式各样。四六级考试结束后，有人在小红书发帖称，自己用千问App押中了 作文题目。除了备考，论文场景也被频繁提起：不少学生把它当成"格式克星"，能直接套用内置的近千 所高校论文模板，把原本最耗时间的页眉页脚、目录、参考文献样式调整压缩到几分钟内完成。 这股热度背后，是学生对"会员墙"的集体疲劳。过去一年，写作、翻译、资料检索、PPT生成等学 习类AI工具密集上线，但多数产品把核心能力切成碎片、再用订阅逐层解锁，用户不得不在多个App之 间拼凑工作流。 近日，阿里巴巴旗下千问App宣布将学习、文档等核心能力向用户免费开放，这一举措很快在高校 学生群体中引发关注。多名学生在社交平台分享称，如果将PPT制作、资料下载、翻译、文档写作等常 用工具的订阅费用叠加计算，千问的免费策略一年可以帮他们省下最高2000元的会员开支。 | 阿里千问 免费功能 | AI PPT | Al 写作 | Al 文库 | Al 讲题 | ...
