Implications of fetal premature atrial contractions: systematic review
Ultrasound in Obstetrics &Gynecology, Volume 60, Issue 6, Page 721-730, December 2022., 2022 ABSTRACT Objective Fetal heart‐rate irregularities occur in 1–2% of pregnancies and are usually caused by premature atrial contractions (PAC). Although PAC are considered benign, they may be associated with cardiac defects and tachyarrhythmia. We aimed to determine the incidence of congenital heart defects (CHDs) and complications in fetuses with PAC ...

Journal of Traumatic Stress, Volume 34, Issue 3, Page 616-627, June 2021., 2021 Abstract Posttraumatic stress disorder (PTSD) has been linked to increased prevalence and incidence of cognitive and physical impairment. When comorbid, these conditions may be associated with poor long‐term outcomes. We examined associations between chronic PTSD and symptom domains with cognitive and physical functioning in World Trade Center (WTC ...

An algorithm for chip surface defect detection based on sequential similarity and light source automatic adjustment [PDF]
, 2017 为了解决当前缺陷检查算法在保护罩反光环境下易导致采集芯片连接器图像光照不均,使其缺陷检测精度较低,无法精确定位出浅插与破损的不足,设计了基于序贯相似性检测匹配与光源自动调节的芯片连接器表面缺陷检测识别算法。首先,基于序贯相似性检测匹配,定位出连接器位置,提取出连接器不良常发区域;然后设计了光源自动调节机制,视觉软件通过光源数字控制器SDK与网线触发光源关闭或调暗,消除保护罩反光对图像质量的影响;最后采用线检测,统计缺陷区域二值图特征,完成缺陷检查。实验数据显示,与当前缺陷检查技术相比 ...

Dianci bileiqi, 2022 由于电力线路绝缘子故障导致输电系统故障，基于高空作业平台的绝缘子检测系统得到了广泛的应用。绝缘子缺陷检测是在航空图像复杂背景下进行的，检测识别具有一定的挑战性。而基于主观的特征或浅层学习技术的传统方法只能在特定的检测条件下定位绝缘子并检测故障。为此，本研究讨论了利用航空图像自动检测绝缘子缺陷，精确定位从实际检测环境采集的输入图像中出现的绝缘子缺陷。提出了一种新颖的深卷积神经网络(convolutional neural network, CNN)级联结构，用于绝缘子缺陷的定位和检测 ...

基于改进Cascade R-CNN算法的多类型绝缘子缺陷图像联合检测
Dianci bileiqi, 2022 当前输电线路巡检工作主要采用无人机巡检的方式来完成,利用人工智能技术助力巡检图像的缺陷识别已成为趋势。以往绝缘子缺陷检测研究大部分集中于绝缘子爆片类缺陷的检测,提出了一种改进的Cascade R-CNN算法,基于绝缘子缺陷数据建立绝缘子缺陷数据集。该算法主要针对绝缘子爆片、绝缘子电弧烧伤及绝缘子伞裙破损的多类型绝缘子缺陷联合检测。首先,针对目标比例小导致生成的anchor正负样本比例失衡的现象,将损失函数更改为Focal loss;然后引入了RoI Align方法以解决小目标的漏检;通过联合绝缘子串模型,

The Oncologist, Volume 24, Issue 11, Page 1416-1419, November 2019., 2019 Abstract Immune checkpoint blockade (ICB) is an approved therapy for advanced metastatic mismatch repair (MMR)‐deficient cancer regardless of tissue of origin. Although therapy is effective initially, recurrence rates are significant, and long‐term outcomes remain poor for most patients.
