BACKGROUND Common diseases after radical gastrectomy include cholecystitis and pancreatitis,but the sudden onset of acute appendicitis in a short period following radical gastrectomy is very rare,and its clinical symptoms are easily misdiagnosed as duodenal stump *** SUMMARY This is a case report of a 77-year-old woman with lower right abdominal pain 14 d after radical resection of gastric *** pain was not relieved by conservative treatment,and her inflammatory markers were *** tomography showed effusion in the perihepatic and hepatorenal spaces,right paracolic sulcus and pelvis,as well as exudative changes in the right iliac *** puncture revealed a slightly turbid yellow-green *** exploration showed a swollen appendix with surrounding pus moss and no abnormalities of the digestive anastomosis or stump;thus,laparoscopic appendectomy was *** patient recovered well after the *** pathology showed acute purulent *** patient continued adjuvant chemotherapy after surgery,completing three cycles of oxaliplatin plus S-1(SOX regimen).CONCLUSION Acute appendicitis in the short term after radical gastrectomy needs to be differentiated from duodenal stump leakage,and early diagnosis and surgery are the most important means of treatment.

Surface particles growing in large aperture optical element （LAOE） have significant impact on LAOE＇s stable operation. It is a challenge for the online system to inspect the particles with long working distance, enough precision and high efficiency because of the system constraints. In this paper, an effective and portable inspection instrument is designed based on dark-field imaging principle. A Nikon lens and an industrial high definition （HD） camera are selected to construct the vision system to inspect particles of microns size spreading over hundreds of millimeters. Using two motors and other mechanical structure, the system can realize auto-focus and image rectification functions. The line light sources are installed on both sides of the LAOE in a sealed box while the vision system is portable and working outside the box. An adaptive binarization method is proposed to process the captured dark-field image. The distribution of particles on the LAOE＇s surface is investigated. Because of the high resolution of the captured image, the SSE2 instructions optimization method is used to reduce the time cost of the algorithm. Experiments show that the instrument can inspect LAOE effectively and accurately.

This paper is concerned with the waves generated by a 3 D body advancing beneath the free surface with constant speed in a two layer fluid of finite depth. By applying Green’s theorem, a layered integral equation system based on the Rankine source for the perturbed velocity potential generated by the moving body was derived with the potential flow theory. A four node isoparametric element method was used to treat with the solution of the layered integral equation system. The surface and interface waves generated by a moving ball were calculated numerically. The results were compared with the analytical results for a moving source with constant velocity.

钙钛矿量子点优异的光学特性使其成为太阳能电池、发光二极管、激光器、探测器等常规光电器件以及单光子源、纠缠光子源等非经典量子光源的理想材料.对于单个钙钛矿量子点荧光闪烁特性的研究可以为微纳光电器件的制备提供技术支撑.针对如何有效分析钙钛矿单量子点的荧光闪烁机制这一关键问题,本文基于荧光轨迹进行亮、暗态的幂律分析发现:弱光激发下钙钛矿单量子点荧光的亮、暗态概率密度服从幂律统计,量子点的荧光闪烁是表面俘获态的活化和非活化造成的;强光激发下,单量子点荧光的亮态概率密度服从指数截断的幂律统计,量子点的荧光闪烁是量子点充、放电和表面俘获共同作用的结果.

对"泸州遗赠案"争论的分析表明,原则裁判面临着前提难以达成共识、原则间的权衡问题以及多元价值观之间的冲突等困境。程序性控制、利益衡量方法、类型化尝试以及可接受性视角的转换等方案,可用于消解原则裁判中的紧张关系,提高原则裁判的合法性与合理性。对适用《民法通则》第七条进行裁判的243个样本案件的统计分析,阐明了适用公序良俗原则条款进行裁判的时间、地区、审级、案由、前提条件、原则类型、裁判模式以及原则在裁判依据中的地位,揭示了我国司法实践中适用公序良俗原则条款进行裁判的四种主要原则类型、两种典型模式以及援引原则条款的四种形式。在司法实践中,公序良俗原则条款最主要指向国家政策、合同效力、家庭关系和民间习俗四种类型,"规则漏洞—原则证成模式"和"依既有规则可解决—规则证成模式"是最常见的两种模式,公序良俗原则单独适用以及分别与《民法通则》第四、五、六条同时适用是法院援引法律原则的四种主要形式。统计还表明,在原则裁判的正当化方案中,程序性控制机制常常失灵,利益衡量方法存在局限,既有的类型化理论也需要更新。
