目的了解2012—2021年重庆市长寿区外环境禽流感病毒阳性及分布情况,为防控辖区人感染禽流感疫情提供数据支撑。方法采集2012—2021年重庆市长寿区外环境4种场所的5种类型外环境标本,采用荧光定量PCR方法对标本进行流感病毒甲型通用、H5、H7和H9亚型流感病毒检测。率的比较采用χ^(2)检验,P<0.05为差异有统计学意义。结果2012—2021年重庆市长寿区采集禽流感外环境标本1074份,检出甲型流感病毒阳性标本202份,阳性率为18.81%,各年度均有阳性标本检出,阳性率差异无统计学意义(χ^(2)=6.835,P=0.650);阳性样本中H5亚型占30.69%,H9亚型占51.98%、H5+H9混合型占13.37%,其他型别(甲型非H5、非H9、非H7型别)占3.96%;4类场所中仅城乡活禽市场中检出阳性,阳性率为29.28%;5种类型外环境标本阳性率差异有统计学意义(χ^(2)=89.561,P<0.001),其中清洗禽类污水禽流感病毒检出阳性率最高(35.09%),其次为宰杀或摆放禽肉案板表面擦拭(30.20%);不同季度采集的标本均可检测到阳性,各季度阳性率差异有统计学意义(χ^(2)=13.312,P<0.001),第3季度标本阳性率最高(25.00%),其次为第1季度(20.24%)。结论现有监测数据分析表明:重庆市长寿区活禽市场外环境有长期被甲型流感病毒污染的风险,应警惕活禽市场外环境长期阳性引起禽流感病毒传人的情况发生。

大跨度异形空间网架结构在大型公共建筑项目中广泛应用,但该类结构存在大量球形构件,传统全站仪监测的测量精度和效率较低,因此提出一种基于激光点云的大跨度异形空间网架球节点中心点坐标高效自动检测方法。利用三维激光扫描仪获取结构成形态的钢结构屋盖点云数据,然后对点云进行降噪处理,基于深化设计模型并根据后续工序的精度要求设置空间域,提取目标点云,最后采用编程算法对焊接球节点的中心点坐标实现自动化批量提取。为验证拟合球体中心点精度,对比了深化设计模型球节点与点云重构球节点的半径。以杭州西站大跨度异形空间网架焊接球节点为分析对象,结果表明,由该方法提取得到的大跨度异形空间网架球节点坐标精度高、效率大幅提升,具有良好的工程应用前景。

为了提升推荐模型的预测精度,传统方法通常是利用更多的附加信息参与模型的构建.然而,此类方法在提高算法精度的同时也大大增加了算法的时间开销,同时对数据集也存在一定的要求.为了解决上述问题,提出一种基于Bagging集成的矩阵分解模型.该模型根据用户、产品评分数为基学习器动态分配权重,并通过加权求和得到预测评分.在三个不同规模的真实数据集上的实验结果显示:该动态加权Bagging矩阵分解模型拥有与传统矩阵分解模型一样的时间消耗,并且在各个衡量指标上都优于传统的矩阵分解模型。
