6电力系统经济调度中遗传算法的比较研究显示文摘本文介绍了在电力经济调度中用于改善系统运行性能的遗传算法的某些修改。目的是试图找出供遗传算法使用的最佳运行点。为了改善运行性能,涉及到问题的两个阶段:即首先是选择一种适当的遗传策略,其次是为所选定的遗传策略对各种参数的值进行协调。这两个阶段均已在六机系统中经过试验,并按照在线及离线两种情况对试验结果进行了比较。全部研究工作清楚地表明,采用先进的遗传算子及优化选择参数值能使系统性能显著增强。Y.H.

7Randomised controlled trial comparing modified Sano's and narrow band imaging international colorectal endoscopic classifications for colorectal lesions显示文摘AIM To assess the utility of modified Sano′s(MS) vs thenarrow band imaging international colorectal endoscopic(NICE) classification in differentiating colorectal polyps.METHODS Patients undergoing colonoscopy between 2013 and 2015 were enrolled in this trial.Based on the MS or the NICE classifications,patients were randomised for real-time endoscopic diagnosis.This was followed by biopsies,endoscopic or surgical resection.The endoscopic diagnosis was then compared to the final(blinded) histopathology.The primary endpoint was the sensitivity(Sn),specificity(Sp),positive predictive value(PPV) and negative predictive value(NPV) of differentiating neoplastic and non-neoplastic polyps(MSⅡ/Ⅱo/Ⅲa/Ⅲb vs I or NICE 1 vs 2/3).The secondary endpoints were 'endoscopic resectability'(MSⅡ/Ⅱo/Ⅲa vs Ⅰ/Ⅲb or NICE 2 vs 1/3),NPV for diminutive distal adenomas and prediction of post-polypectomy surveillance intervals.RESULTS A total of 348 patients were evaluated.The Sn,Sp,PPV and NPV in differentiating neoplastic polyps from non-neoplastic polyps were,98.9%,85.7%,98.2% and 90.9% for MS;and 99.1%,57.7%,95.4% and 88.2% for NICE,respectively.The area under the receiver operating characteristic curve(AUC) for MS was 0.92(95%CI:0.86-0.98);and AUC for NICE was 0.78(95%CI:0.69,0.88).The Sn,Sp,PPV and NPV in predicting 'endoscopic resectability' were 98.9%,86.1%,97.8% and 92.5% for MS;and 98.6%,66.7%,94.7% and 88.9% for NICE,respectively.The AUC for MS was 0.92(95%CI:0.87-0.98);and the AUC for NICE was 0.83(95%CI:0.75-0.90).The AUC values were statistically different for both comparisons(P = 0.0165 and P = 0.0420,respectively).The accuracy for diagnosis of sessile serrated adenoma/polyp(SSA/P) with high confidence utilizing MS classification was 93.2%.The differentiation of SSA/P from other lesions achieved Sp,Sn,PPV and NPV of 87.2%,91.5%,89.6% and 98.6%,respectively.The NPV for predicting adenomas in diminutive rectosigmoid polyps(n = 150) was 96.6% and 95% with MS and NICE respectively.The calculated accuracy of post-polypectomy surveillance for MS group was 98.2%(167 out of 170) and for NICE group was 92.1%(139 out of 151).CONCLUSION The MS classification outperformed the NICE classification in differentiating neoplastic polyps and predicting endoscopic resectability.Both classifications met ASGE PIVI thresholds.Leonardo Zorrón Cheng Tao Pu Kuan Loong Cheong Doreen Siew Ching Koay Sze Pheh Yeap Amanda Ovenden Mahima Raju Andrew Ruszkiewicz Philip W Chiu James Y Lau Rajvinder Singh 2018World Journal of Gastrointestinal Endoscopy2018,10,9:4

9Tagging and Utilization Bruchid Resistance Gene Using PCR Markers in Mungbean显示文摘Sixteen mungbean lines were analyzed using 56 random primers. Different DNA bands were detected between Bruchid resistant lines and susceptible lines. According to the cluster results, the 16 lines can be divided into four groups, including brucid resistant wild types, resistant cultivated lines, resistant progenies and a mixed group. BSA method was used to identify DNA markers that related with bruchid resistant gene by using resistant line and susceptible line and their F2 progeny. One codominant marker was identified, which generated a fragment of 1.79 kb in resistant lines and 1.03 kb in susceptible lines. Finally, this codominant marker was considered to be tightly linked with bruchid resistant gene and could be useful in resistant germplasm identification and marker-assisted selection.CHENG Xu-zhen WANG Su-hua WU Shao-yu ZHOU Ji-hong WANG Shu-min Charles Y Yang 2005Agricultural Sciences in China2005,4,8:3

19收缩压和舒张压变异性对脑卒中患者血管事件的不同影响显示文摘较高的血压变异性(blood pressure variability,BPV)是心血管病的危险因素。然而,在引发不同的血管事件时,收缩压变异性(systolic blood pressure variability,SBPV)和舒张压变异性(diastolic blood pressure variability,DBPV)是否存在不同作用仍不清楚。本研究旨在探讨SBPV或DBPV对急性缺血性脑卒中(acute ischaemic stroke,IS)或短暂性脑缺血发作(transient ischaemic attack,TIA)患者血管事件的作用是否存在区别。周卫(译) 袁源(摘) 叶鹏(审校) Dai L Cheng A Hao X Xu J Zuo Y Wang A Meng X Li H Wang Y Zhao X Wang Y 2020中华高血压杂志2020,28,11:2
