在对医学影像自动生成文本报告的过程中,针对病灶尺寸小、形状不规则、训练数据量少等因素易导致影像报告出现误诊、漏诊的问题,提出变尺度特征融合与交叉训练的医学报告生成方法.首先将条件全局池化后的粗粒度特征与随机丢弃后的细粒度特征相融合,增强模型对不同尺度病灶的感知能力;然后通过整体数据和局部细节双路交叉训练的策略间接丰富数据集,增强模型的鲁棒性,并在双路中分别使用通道分离思想进一步挖掘影像的通道信息;最后通过多头注意力编解码网络,得到准确的医学报告.在IU-X-Ray和MIMIC-CXR数据集上与其他多种方法进行实验的结果表明,METEOR与BLEU-2分数分别提升5.70%和3.13%,所提方法可以有效地提升生成报告的可读性与准确性.

江浙士人史善长是乾嘉时期著名的游幕诗人,曾在西北幕游数年。其间,他用诗歌书写边塞的气候、风物、历史遗迹,以及自己所经历的西北回民的暴动。后来,他又入毕沅幕府,耳闻目睹发生于贵州、湖南的苗民起义与湖北的白莲教起义,并用诗歌进行书写。史善长的这些书写,忠实记录了重要的历史事件,提供了关于这一时期重要的历史资料,不但具有文学价值,而且具有极高的史学价值,使其诗歌创作具有诗史意义。而他的诗歌风格随着幕游地的变迁也相应地发生改变,由幕游之前的“豪宕感激”变为幕游之后的“慷慨激昂”。史善长的诗歌书写在清代游幕诗人中具有典型意义。

输电线路是电网电能传输的重要通道,输电线路带电作业对提高供电可靠率、减少停电时间作出重要贡献,它已经成为提高电网经济效益和电网设备安全运行的重要检修手段。本文针对输电线路直线塔带电检修时遇到天气突变,恰好遭遇施工设计时留下的缺陷,例如金具尺寸不吻合等特殊情况,导致不能快速恢复直线串导线的支撑连接,不能立即撤下作业工器具和撤离人员,以至于留下设备和人员的安全隐患,提出研制输电线路带电作业直线串导线临时防雨支撑棒专用工具的思路,起到临时支撑导线,保障人员和工具安全撤离,等待风雨过后再完成作业任务的作用。并介绍了导线临时防雨支撑棒工具的实用性,极大地提高了目前带电检修输电线路直线塔工作的安全性,推动带电作业的发展。

人诺如病毒(Human norovirus, HuNoV)属于杯状病毒科诺如病毒属,为无包膜单股正链RNA病毒,易发生重组,变异快,传染性强,致病剂量低;人群普遍易感,是全球急性胃肠炎(Acute gastroenteritis, AGE)的主要病因之一。HuNoV感染后,≤5岁儿童和>65岁老年人群中少数人会因大量失水导致电解质紊乱等重症,甚至死亡。HuNoV还易在封闭和/或半封闭人群拥挤的场所引起AGE暴发;新的变异株或/和型别出现,会导致暴发事件大幅升高,甚至出现大流行。因此,HuNoV导致了沉重的疾病负担,是全球性的公共卫生问题。本文综述了全球HuNoV AGE的流行病学研究进展,还从宿主、病毒和环境等多个方面综述了当前影响HuNoV AGE流行特征的主要影响因素,为HuNoV AGE的防控提供支撑。
