acute cardiac tamponade occurs in 0.1%-2% of patients undergoing catheter ablation of atrial fibrillation （AF） in experienced centers.1-4 Once it is diagnosed, emergency pericardiocentesis is required.5 With the intervention, sternotomy and open surgical repair can be avoided in the most patients6. Generally, pericardial blood is reinjected directly back into the patient through the femoral venous sheath in order to invert hemodynamic instability promptly.

猴群算法(MA)是一种只适于求解连续变量优化问题的群智能算法.针对MA的局限并结合输电网扩展规划问题的特点,设计了能够求解含有离散变量优化问题的离散猴群算法(DMA).算法中提出的大、小2种爬过程解决了原猴群算法求解离散优化问题时爬过程失效的问题,合作过程和随机扰动机制的引入也提高了算法的计算效率.算例结果表明,DMA计算速度快,鲁棒性强,用很小的猴群规模就能够对不同维数的输电网扩展规划问题均达到很好的计算效果.

Since fibre-reinforced polymer(FRP) and stainless steel(SS) offer advantages of corrosion resistance and hybrid confinement, this study proposed a new type of composite column: sea sand concrete(SSC)-filled SS tubular columns with an inner FRP tube(CFSTFs) to help exploit abundant ocean resources in marine engineering. To study compressive behaviours of these novel members, eight CFSTFs and two SSC-filled SS tubular columns(CFSTs)were tested under axial compression. Their axial load-displacement curves, axial load-strain curves in SS or FRP tubes were obtained, and influences of key test parameters(the existence of glass FRP(GFRP) tubes, steel tube shapes, and GFRP tube thicknesses and diameters) were discussed. Further, specimen failure mechanism was analyzed employing the finite element method using ABAQUS software. Test results confirmed the excellent ductility and load-bearing capacity of CFSTFs. The existence of GFRP tubes inside can postpone SS tube buckling, and the content of inner FRP tubes, particularly increasing diameters, was found to improve compressive behaviours. GFRP contents helped develop the second elastic-plastic stage of the load-displacement curves. Furthermore, the bearing capacity of CFSTFs with a circular cross-section was approximately 26% higher than that with a square cross-section, and this difference narrowed with the increase in GFRP ratios.

充分挖掘负荷侧资源的响应潜力是提升负荷资源调控能力的有效手段之一。为有效感知负荷的响应潜力,提出了一种基于SWARA(逐步加权评估比率分析)-CRITIC(基于相关性的权重求取)-MARCOS(基于折中方案的备选方案排序)的负荷侧资源响应潜力评估方法。首先,基于负荷、经济、社会和系统层面构建负荷响应潜力的多维影响因素指标,并采用模糊数理论对指标权重和负荷的响应潜力进行评估;其次,将SWARA和CRITIC相结合计算各指标的综合权重;然后,采用MARCOS综合指标权重计算各负荷的响应潜力效用函数值,得到各类负荷的响应潜力排序结果;最后,以上海市部分可调度用户负荷为基础的算例验证了所提方法的有效性。

This article presents the designing and fabrication of a microfluoidic chip with an integrated supported-liquid-membrane extraction-back-extraction and chip-based capillary electrophoresis system(SLMEBE-CCE).A 3-dimensional channel network for the SLMEBE-CCE system was fabricated with a four-layer glass/PTFE-membrane hybrid structure. With a gravity pump for sample and back-extraction solution delivery and a multi-channel high-voltage supply for CCE separation,the microchip with the coupled SLMEBE-CCE system was demonstrated by the pre-concentration,separation and detection of a mixed solution of fluorescein and butyl-rhodamine *** to chip-based CCE without SLMEBE,the developed SLMEBE-CCE system produced a 7-fold increase in the signal of the model analyte of fluorescein and a 4-fold decrease in the signal of the model co-existing compound of butyl-rhodamine B.
