AIM： TO investigate the safety of adult-to-adult living donor liver transplantation （A-A LDLT） in both donors and recipients. METHODS： From January 2002 to July 2006, 50 cases of A-A LDLT were performed at West China Hospital, Sichuan University, consisting of 47 cases using right lobe graft without middle hepatic vein （HHV）, and 3 cases using dual grafts （one case using two left lobe, 2 using one right lobe and one left lobe）. The most common diagnoses were hepatitis B liver cirrosis, 30 （60%） cases; and hepatocellular carcinoma, 15 （30%） cases in adult recipients. Among them, 10 cases had the model of end-stage liver disease （HELD） with a score of more than 25. Donor screening consisted of reconstruction of the hepatic blood vessels and biliary system with 3-dimension computed tomography and volumetry of whole liver and right liver volume. Various improved surgical techniques were adopted in the procedures for both donors and recipients. RESULTS： Forty-nine right lobes and 3 left lobes （2 left lobe grafts for 1 recipient, 1 left lobe graft for 1 recipient who had received right lobe graft donated by relative living donor） were obtained from 52 living donors. The 49 right lobe grafts, without HHV, weighed 400 g-850 g （media 550 g）, and the ratio of graft volume to recipient standard liver volume （GV/SLV） ranged from 31.74% to 71.68% （mean 45.35%）. All donors＇ remnant liver volume was over 35% of the whole liver volume. There was no donor mortality. With a follow- up of 2-52 mo （media 9 too）, among 50 adult recipients, complications occurred in 13 （26%） cases and 4 （8%） died postoperatively within 3 mo. Their 1-year actual survival rate was 92%.CONCluSION： When preoperative CT volumetry shows volume of remnant liver is more than 350, the ratio of right lobe graft to recipients standard liver volume exceeding 40%, A-A LDLT using right lobe graft without MHV should be a very safe procedure for both donors and recipients, otherwise dual grafts liver transplantation

【目的】设计喂入量模糊控制系统,为提高联合收获机收获效益提供支撑。【方法】采用油压力传感器检测喂入量,根据滚筒扭矩与行走速度之间的关系,建立喂入量模型。设计模糊控制器并在MATLAB下进行仿真,利用PLC建立模糊控制系统,通过电控静液压系统控制行走速度来调整喂入量,并以新疆-3稻麦联合收获机为试验机型,进行喂入量自动控制田间试验。【结果】基于模糊控制系统调整后的联合收获机损失率小于1.2%,破碎率小于1.0%,损失率和破碎率均与经验丰富的驾驶员手动控制结果基本持平,符合国标要求。在作物密度不均匀的区域进行试验,指令喂入量取2kg/s时计算平均喂入量为2.04kg/s;指令喂入量取3kg/s时计算平均喂入量为3.08kg/s,喂入量能稳定控制在±10%的范围以内。【结论】联合收获机喂入量模糊控制系统稳定可靠,能提高收获效益。

Carbon materials are widely recognized as highly promising electrode materials for various energy storage system *** tar residues(CTR),as a type of carbon-rich solid waste with high value-added utilization,are crucially important for the development of a more sustainable *** this study,we employed a straightforward direct carbonization method within the temperature range of 700-1000℃to convert the worthless solid waste CTR into economically valuable carbon materials as anodes for potassium-ion batteries(PIBs).The effect of carbonization temperature on the microstructure and the potassium ions storage properties of CTR-derived carbons(CTRCs)were systematically explored by structural and morphological characterization,alongside electrochemical performances *** on the co-regulation between the turbine layers,crystal structure,pore structure,functional groups,and electrical conductivity of CTR-derived carbon carbonized at 900℃(CTRC-900H),the electrode material with high reversible capacity of 265.6m Ah·g^(-1)at 50 m A·g^(-1),a desirable cycling stability with 93.8%capacity retention even after 100 cycles,and the remarkable rate performance for PIBs were ***,cyclic voltammetry(CV)at different scan rates and galvanostatic intermittent titration technique(GITT)have been employed to explore the potassium ions storage mechanism and electrochemical kinetics of *** indicate that the electrode behavior is predominantly governed by surface-induced capacitive processes,particularly under high current densities,with the potassium storage mechanism characterized by an“adsorption-weak intercalation”*** work highlights the potential of CTR-based carbon as a promising electrode material category suitable for high-performance PIBs electrodes,while also provides valuable insights into the new avenues for the high value-added utilization of CTR.

运动估计是视频压缩中最重要的环节.H.264编码器由于采用了高精度运动矢量,计算量迅速增长,运动估计消耗整个编码时间80%左右.本文在分析UMHexagonS算法的基础上,分别对UMHexagonS算法中搜索窗口大小的选择、大六边形搜索和小六边形(小钻石)搜索模式三方面做了优化,在保持了原有图象质量的情况下有效的节省了运动估计时间.通过对各种测试序列的实验证明,优化后的算法与UMHexagonS算法相比,在重建图象质量和码率接近的情况下,运动估计时间平均节省了18.292%,降低了算法的复杂度,提高了编码器的实时性.
