A Novel Solution Based on Differential Evolution for Short-Term Combined Economic Emission Hydrothermal Scheduling

This paper presents a novel approach based on differential evolution for short-term combined economic emission hydrothermal scheduling, which is formulated as a bi-objective problem: 1) minimizing fuel cost and 2) minimizing emission cost. A penalty factor approach is employed to convert the bi-objective problem into a single objective one. In the proposed approach, heuristic rules are proposed to handle water dynamic balance constraints and heuristic strategies based on priority list are employed to repair active power balance constraints violations. A feasibility-based selection technique is also devised to handle the reservoir storage volumes constraints. The feasibility and effectiveness of the proposed approach are demonstrated and the test results are compared with those of other methods reported in the literature. Numerical experiments show that the proposed method can obtain better-quality solutions with higher precision than any other optimization methods. Hence, the proposed method can well be extended for solving the large-scale hydrothermal sched-uling.

Combination of acoustic radiation force impulse imaging, serological indexes and contrast-enhanced ultrasound for diagnosis of liver lesions

AIM To assess the value of combined acoustic radiation force impulse(ARFI) imaging, serological indexes and contrast-enhanced ultrasound(CEUS) in distinguishing between benign and malignant liver lesions. METHODS Patients with liver lesions treated at our hospital were included in this study. The lesions were divided into either a malignant tumor group or a benign tumor group according to pathological or radiological findings. ARFI quantitative detection, serological testing and CEUS quantitative detection were performed and compared. A comparative analysis of the measured indexes was performed between these groups. Receiver operating characteristic(ROC) curves were constructed to compare the diagnostic accuracy of ARFI imaging, serological indexes and CEUS, alone or in different combinations, in identifying benign and malignant liver lesions. RESULTS A total of 112 liver lesions in 43 patients were included, of which 78 were malignant and 34 were benign. Shear wave velocity(SWV) value, serum alpha-fetoprotein(AFP) content and enhancement rate were significantly higher in the malignant tumor group than in the benign tumor group(2.39 ± 1.20 m/s vs 1.50 ± 0.49 m/s, 18.02 ± 5.01 ng/m L vs 15.96 ± 4.33 ng/m L, 2.14 ± 0.21 d B/s vs 2.01 ± 0.31 d B/s; P < 0.05). The ROC curve analysis revealed that the areas under the curves(AUCs) of SWV value alone, AFP content alone, enhancement rate alone, SWV value + AFP content, SWV value + enhancement rate, AFP content + enhancement rate and SWV value + AFP content + enhancement rate were 85.1%, 72.1%, 74.5%, 88.3%, 90.4%, 82.0% and 92.3%, respectively. The AUC of SWV value + AFP content + enhancement rate was higher than those of SWV value + AFP content and SWV value + enhancement rate, and significantly higher than those of any single parameter or the combination of any two of parameters.CONCLUSION The combination of SWV, AFP and enhancement rate had better diagnostic performance in distinguishing between benign and malignant liver lesions than the use of any single parameter or the combination of any two of parameters. It is expected that this would provide a tool for the differential diagnosis of benign and malignant liver lesions.

Q学习差分进化算法求解热电动态经济排放调度

热电联产动态经济排放调度同时考虑了燃料成本花费和污染气体排放两个目标值,且下一时间段的热电产量受当前时间段热电产量的影响,这是近年来电力系统运行中的一个重要问题。文中提出一种基于Q学习强化多目标差分进化(Q Learning Multi-Objective Differential Evolution,QLMODE)算法,以此求解热电联产动态经济排放调度(Combined Heat and Power Dynamic Economic Emission Dispatch,CHPDEED)问题。在QLMODE中,采用Q学习技术调整算法的比例因子参数,即在迭代过程中利用子代解和父代解之间的支配关系确定动作奖励和惩罚,并通过Q学习调整参数值,以获得最适合环境模型的算法参数。文中将所提QLMODE用于求解11机组和33机组的热电联产动态经济排放调度问题。仿真结果表明,与4种成熟的多目标优化算法相比,QLMODE算法燃料成本最小,污染气体排放最少,收敛性和多样性指标优于其他4种算法,且QLMODE在两组问题上都获得了更好的Pareto最优前沿。

基于六维辨证观拆解慢性阻塞性肺疾病辨治体系

六维辨证观是综合多种辨证思维所提出的辨证观念,旨在从病因、病位、病期、病性、病势、病理等6个维度对疾病证态进行系统辨析,有利于临床把握整体,抓住机要。慢性阻塞性肺疾病(COPD)是一种以进行性气流受限和持续的呼吸道症状为特征的呼吸系统疾病,发病多责之于肺气本虚,内外感召或他脏及肺,常有慢性肺系疾病迁延日久或先天不足因素。病位主要在肺,最常波及脾肾,病久可牵连心肝及六腑,是典型的多系统复杂疾病。基本病机是本虚标实,即肺脾肾虚损,痰瘀互结成积,除见气虚气滞、阴阳虚损等病理状态外,还最常见痰饮瘀及微型癥瘕等病理产物。本病分期明确,卫气同病、气分期和气营同病阶段病情寒热之性及邪正之势多变,可因病邪性质、季节地域、体质等因素表现不一,需要谨慎判断和用药;气血同病阶段寒热错杂、虚实并见,治疗棘手,恰是中医药发挥优势的大好时机。

“脏络”辨治儿童病

吴敏教授从“土壅木郁,痰瘀互结”分型辨证治疗甲状腺结节经验精粹

甲状腺结节(Thyroid nodule,TN)是临床常见病、多发病。吴敏教授依据临床多年实践经验,认为TN多与情志失调有关,病位涉及肝脾,气滞、痰凝、血瘀为TN主要病理因素,提出“土壅木郁、痰瘀互结”是其核心病机,并将西医的病理分型与中医证型相结合,分型辨证治疗TN,将中西医融会贯通,治疗上以疏肝理气为先,不离健脾助运之法,化痰散结,活血消瘿,对良性TN可以有效缩小甲状腺肿,减轻症状,对于恶性TN可以降低术后复发率,减少西药不良反应等。此外,吴敏教授倡导“防大于治”,临床实践中尤注重中医预防调摄,效果显著。

针药并用从“肾主水”论治五液失常病症

现基于经典理论,剖析五液内涵与“肾主水”理论,总结历代医家诊治经验,探讨从“肾主水”论治五液失常病症。《黄帝内经》首先提出“肾主水”,后世医家不断继承与发展丰富,是现代中医基础理论脏象学说重要组成部分。五脏功能失调均可导致所主的五液摄纳失常,肾之液虽表现为“唾”,但因主持全身水液的输布和排泄,其余四脏之液的疏泄失常与肾脏的功能亦密切相关,如“多涕”病症可能与肺卫相关性不大,而以肾脏虚弱为主。基于经典理论和名家诊治经验,中医在整体观念的指导下,“五脏之五液”以肾水为根本,五液之间相互影响,不独主于本脏,牵一发而动全身,治疗以调护根本为主兼顾它脏,并提出针药并用治疗五液病症思路与方法,为临床治疗五液相关病症拓展辨证思路,启发辨证思维,有效指导临床实践。

基于分数混合阶的交叠组合稀疏全变分HFOGSTV去噪模型

针对全变分(TV)模型引起的阶梯效应,造成图像出现块状伪影的问题,提出了基于分数混合阶的交叠组合稀疏正则项全变分(HFOGSTV)去噪模型。考虑到交叠组合稀疏正则项与分数阶微分能够抑制全局以及局部的块状伪影的特点,将二者引入TV模型,可以较好地抑制阶梯效应。并引入高阶微分,提高模型的去噪效率,构建了基于HFOGSTV去噪模型。新模型采用交替方向乘子法(ADMM)分解为各个子问题进行依次迭代求解,并选择合适的参数。实验结果表明,HFOGSTV模型与非局部均值去噪(NLM)、TV和混合非凸高所交叠组合稀疏全变分(HNHOTV-OGS)模型相比,峰值信噪比(PSNR)分别提升7.2%、5.3%、1.9%,结构相似性(SSIM)分别提升6.6%、6.1%、3.4%,耗时分别减少89%、51%、45%,不仅有效抑制了阶梯效应,而且去噪效果更佳,运行时长大大降低。
