A 43-year-old Tibeta. female was brought to the department of general surgery with abdominal *** tomography(CT)scan revealed cystic hepatic echinococcosis in the right liver(Figure 1A).Further magnetic resonance cholangiopancreatography showed that there were cyst-biliary communications at right posterior bile duct,and several hydatid cysts inside common bile duct(Figure 1B,yellow arrow head showed rupture,white arrow heads showed bile duct hydatid cysts).Low confluence of right posterior bile duct to the common hepatic duct suggests biliary *** serum tota. bilirubin was normal,serum alkaline phosphata.e and gamma-gluta.yl transpeptidase were elevated mildly with the value of 278 and 107 U/L *** underwent right hemihepatectomy plus choledochoscopic hydatid cysts extraction through right posterior hepatic duct stump(Figure 1C,yellow arrow head showed right posterior bile duct stump,white arrow heads showed bile duct hydatid cysts).To prevent the spread of echinococcosis,we covered the surgical area with hypertonic saline gauze.A large number of hydatid cysts presented inside hepatectomy specimen that mixed with a lot of bile(Figure 1D).Hydatid cyst inside bile duct was removed completely,and postoperative recovery was *** removed all the liver cysts,and no signs of any lesion residue in post-operative image.

新《行政处罚法》增设第41条,其意义在于确立了以“利用电子技术监控设备”为代表的自动化行政在事实认定方面的规范基础,并非构建了一种独立于传统行政程序的新型程序。事实认定由两阶段构成,先形成一定的基础事实,再结合证明标准完成案件事实的推断。基础事实本质上属于法律事实,自动化行政虽能高效获取外在的客观事实,但为确保其符合证据特性仍应经人工审核方能升格为法律事实。基于自动化行政所形成的基础事实并不等同于最终的案件事实。首先,当行政相对人提出异议时,行政机关仍应履行全面调查义务。其次,行政机关得于个案中结合证明标准判断最终的案件事实是否清楚。若案件适用简易程序,则选取优势证明标准,可从电子基础事实出发推断待证事实;若案件适用普通程序,无论采高度盖然性证明标准抑或排除合理怀疑证明标准,均无法基于电子基础事实直接推断待证事实。至此,围绕第41条的电子数据“定案孤证说”无从证立。

近年来,无人机在军用领域和民用领域得到了广泛的应用,给人们带来极大便利的同时也带来了重大的安全挑战,精准识别无人机的需求日益迫切,其中无人机辐射源个体识别方法得到广泛关注和深入研究。基于深度学习的方法因其卓越性能而受到广泛关注,然而这些方法大多依赖于大量独立同分布的训练数据,而在实际应用中,无人机射频数据的采集和标注充满挑战,训练数据和测试数据之间往往存在较大的分布差异。针对无人机射频数据采集和标注困难、训练数据和测试数据分布差异大等现实应用需求,提出了一种面向无人机辐射源个体识别的域适应模型设计方法。采用自助抽样法对无人机数据集进行重采样,增加数据集中的样本多样性。将Transformer编码器与域对抗神经网络结合,使特征在高斯分布下进行优化。引入最大均值差异作为度量方法来减少训练过程中源域和目标域之间的分布差异。基于权重的加权投票法增强模型的泛化性,提高模型适应新环境的能力。实验结果表明,基于3种典型环境,构建6种域适应场景,本文所提的方法识别率高于现有方法约5%。此外,还研究了源域样本数量和目标域样本数量对域适应效果的影响,在目标域含有少量样本时依然可以达到较高的性能,较好地平衡了无人机辐射源个体识别精确度与泛化性、可靠性的需求。
