2Optimal operation of electricity, natural gas and heat systems considering integrated demand responses and diversified storage devices显示文摘In recent years, the increasing penetration level of renewable generation and combined heat and power(CHP) technology in power systems is leading to significant changes in energy production and consumption patterns. As a result, the integrated planning and optimal operation of a multi-carrier energy(MCE) system have aroused widespread concern for reasonable utilization of multiple energy resources and efficient accommodation of renewable energy sources. In this context, an integrated demand response(IDR) scheme is designed to coordinate the operation of power to gas(P2 G) devices, heat pumps,diversified storage devices and flexible loads within an extended modeling framework of energy hubs. Subsequently, the optimal dispatch of interconnected electricity,natural gas and heat systems is implemented considering the interactions among multiple energy carriers by utilizing the bi-level optimization method. Finally, the proposed method is demonstrated with a 4-bus multi-energy systemand a larger test case comprised of a revised IEEE 118-bus power system and a 20-bus Belgian natural gas system.Linna NI Weijia LIU Fushuan WEN Yusheng XUE Zhaoyang DONG Yu ZHENG Rui ZHANG 2018Journal of Modern Power Systems and Clean Energy2018,6,3:30
3Relationship between Cognition Function and Hippocampus Structure after Long-term Microwave Exposure显示文摘Objective To analyze the effects of long-term microwave exposure on hippocampal structure and function in the rat.Methods Experiments were performed on 184 male Wistar rats(three exposure groups and a sham group).Microwaves were applied daily for 6 min over 1 month at average power densities of 2.5,5,and 10 mW/cm2.Learning and memory abilities were assessed by Morris water maze.High performance liquid chromatography was used to detect neurotransmitter concentrations in the hippocampus.Hippocampal structures were observed by histopathological analysis.Results Following long-term microwave exposure there was a significant decrease in learning and memory activity in the 7 d,14 d,and 1 m in all three microwave exposure groups.Neurotransmitter concentrations of four amino acids(glutamate,aspartic acid,glycine,and gamma-aminobutyric acid) in hippocampus were increased in the 2.5 and 5 mW/cm2 groups and decreased in the 10 mW/cm2 group.There was evidence of neuronal degeneration and enlarged perivascular spaces in the hippocampus in the microwave exposure groups.Further,mitochondria became swollen and cristae were disordered.The rough endoplasmic reticulum exhibited sacculated distension and there was a decrease in the quantity of synaptic vesicles.Conclusion These data suggest that the hippocampus can be injured by long-term microwave exposure,which might result in impairment of cognitive function due to neurotransmitter disruption.ZHAO Li PENG Rui Yun WANG Shui Ming WANG Li Feng GAO Ya Bing DONG Ji LI Xiang SU Zhen Tao 2012Biomedical and Environmental Sciences2012,25,2:27
4Three-dimensional cooperative guidance laws against stationary and maneuvering targets显示文摘This paper presents the cooperative strategies for salvo attack of multiple missiles based on the classical proportional navigation(PN) algorithm.The three-dimensional(3-D) guidance laws are developed in a quite simple formulation that consists of a PN component for target capture and a coordination component for simultaneous arrival.The centralized algorithms come into effect when the global information of time-to-go estimation is obtained, whereas the decentralized algorithms have better performance when each missile can only collect information from neighbors.Numerical simulations demonstrate that the proposed coordination algorithms are feasible to perform the cooperative engagement of multiple missiles against both stationary and maneuvering targets.The effectiveness of the 3-D guidance laws is also discussed.Zhao Jiang Zhou Rui Dong Zhuoning 2015Chinese Journal of Aeronautics2015,28,4:28
5Augmented reality technology for preoperative planning and intraoperative navigation during hepatobiliary surgery: A review of current methods显示文摘Background: Augmented reality(AR) technology is used to reconstruct three-dimensional(3D) images of hepatic and biliary structures from computed tomography and magnetic resonance imaging data, and to superimpose the virtual images onto a view of the surgical field. In liver surgery, these superimposed virtual images help the surgeon to visualize intrahepatic structures and therefore, to operate precisely and to improve clinical outcomes.Data Sources: The keywords 'augmented reality', 'liver', 'laparoscopic' and 'hepatectomy' were used for searching publications in the Pub Med database. The primary source of literatures was from peer-reviewed journals up to December 2016. Additional articles were identified by manual search of references found in the key articles.Results: In general, AR technology mainly includes 3D reconstruction, display, registration as well as tracking techniques and has recently been adopted gradually for liver surgeries including laparoscopy and laparotomy with video-based AR assisted laparoscopic resection as the main technical application. By applying AR technology, blood vessels and tumor structures in the liver can be displayed during surgery,which permits precise navigation during complex surgical procedures. Liver transformation and registration errors during surgery were the main factors that limit the application of AR technology.Conclusions: With recent advances, AR technologies have the potential to improve hepatobiliary surgical procedures. However, additional clinical studies will be required to evaluate AR as a tool for reducing postoperative morbidity and mortality and for the improvement of long-term clinical outcomes. Future research is needed in the fusion of multiple imaging modalities, improving biomechanical liver modeling,and enhancing image data processing and tracking technologies to increase the accuracy of current AR methods.Rui Tang Long-Fei Ma Zhi-Xia Rong Mo-Dan Li Jian-Ping Zeng Xue-Dong Wang Hong-En Liao Jia-Hong Dong 2018Hepatobiliary & Pancreatic Diseases International2018,17,2:27

7Effects of pH and particle size on kinetics of nitrobenzene reduction by zero-valent iron显示文摘Nitrobenzene has been considered as a significant groundwater contaminant due to its wide usage in explosives, insecticides, herbicides, pharmaceuticals and dyes. Nitrobenzene is of environmental concern because of its toxicity. In the presence of zero-valent iron (ZVI), reduction of the nitro group is the dominant transformation process for nitrobenzene. A series of experiments were carried out to investigate the kinetics of nitrobenzene reduction by ZVI and the effects of pH and ZVI particle size on nitrobenzene removal in groundwater. The results indicated that nitrobenzene could be reduced to aniline by ZVI; the reduction of nitrobenzene by ZVI followed a pseudo first-order kinetics; the observed nitrobenzene reduction rate constant (k obs ) was 0.0006 min 1 and the half-life of nitrobenzene (t 1/2 ) was 115.5 min; the mass balance achieved 87.5% for nitrobenzene reduction by the 1 mm ZVI particle and the final removal efficiency was 80.98%. In addition, the pH and ZVI particle size were found to exhibit significant influences on the nitrobenzene reduction. The observed nitrobenzene reduction rate constant linearly decreased with increase pH and the data fitted on polynomial regression equation for the observed nitrobenzene reduction rate constant and ZVI particle size. Therefore, use of ZVI based permeable reactive barrier technology to remedy nitrobenzene contaminated groundwater was feasible.Jun Dong Yongsheng Zhao Ran Zhao Rui Zhou 2010Journal of Environmental Sciences2010,22,11:23
8Effect and Safety of Guanxinning Tablet(冠心宁片) for Stable Angina Pectoris Patients with Xin(Heart)-Blood Stagnation Syndrome:A Randomized,Multicenter,Placebo-Controlled Trial显示文摘Objective: To investigate the effect and safety of Guanxinning Tablet(冠心宁片, GXN) for the treatment of stable angina pectoris patients with Xin(Heart)-blood stagnation syndrome(XBSS). Methods: One hundred and sixty stable angina pectoris patients with XBSS were randomly assigned to receive GXN(80 cases) or placebo(80 cases, Guanxinning simulation tablets, mainly composed of lactose), 4 tablets(0.38 g/tablet), thrice daily for 12 weeks. After treatment, an exercise stress test(treadmill protocol), Chinese medicine(CM) syndrome score, electrocardiogram(ECG), and nitroglycerin withdrawal rate were evaluated and compared in the patients between the two groups. Meanwhile, adverse events(AEs) were evaluated during the whole clinical trial. Results: Compared with the control group, the time extension of exercise duration in the GXN group increased 29.28±17.67 s after treatment(P>0.05);moreover, the change of exercise duration in the GXN group increased 63.10±96.96 s in subgroup analysis(P<0.05). The effective rates of angina pectoris, CM syndrome and ECG as well as nitroglycerin withdrawal rate were 81.33%, 90.67%, 45.76%, and 70.73%, respectively in the GXN group, which were all significantly higher than those in the control group(40.58%, 75.36%, 26.92%, 28.21%, respectively, P<0.05). Conclusion: GXN was a safe and effective treatment for stable angina pectoris patients with XBSS at a dose of 4 tablets, thrice daily.SUN Ming-yue MIAO Yang JIN Min DONG Yao-rong LIU Shu-rong WANG Mu-lan GAO Rui 2019Chinese Journal of Integrative Medicine2019,25,9:22

10Observation and analysis of atmospheric volatile organic compounds in a typical petrochemical area in Yangtze River Delta, China显示文摘Volatile organic compounds(VOCs) are a kind of important precursors for ozone photochemical formation. In this study, VOCs were measured from November 5 th, 2013 to January 6 th, 2014 at the Second Jinshan Industrial Area, Shanghai, China. The results showed that the measured VOCs were dominated by alkanes(41.8%), followed by aromatics(20.1%), alkenes(17.9%), and halo-hydrocarbons(12.5%). The daily trend of the VOC concentration showed a bimodal feature due to the rush-hour traffic in the morning and at nightfall. Based on the VOC concentration, a receptor model of Positive Matrix Factorization(PMF) coupled with the information related to VOC sources was applied to identify the major VOC emissions. The result showed five major VOC sources: solvent use and industrial processes were responsible for about 30% of the ambient VOCs, followed by rubber chemical industrial emissions(23%), refinery and petrochemical industrial emissions(21%), fuel evaporations(13%) and vehicular emissions(13%). The contribution of generalized industrial emissions was about 74% and significantly higher than that made by vehicle exhaust. Using a propylene-equivalent method, alkenes displayed the highest concentration, followed by aromatics and alkanes. Based on a maximum incremental reactivity(MIR)method, the average hourly ozone formation potential(OFP) of VOCs is 220.49 ppbv. The most significant source for ozone chemical formation was identified to be rubber chemical industrial emissions, following one by vehicular emission. The data shown herein may provide useful information to develop effective VOC pollution control strategies in industrialized area.Yunchen Zhang Rui Li Hongbo Fu Dong Zhou Jianmin Chen 2018Journal of Environmental Sciences2018,30,9:21

12Gastrointestinal symptoms: A comparison between patients undergoing peritoneal dialysis and hemodialysis显示文摘AIM: To compare the prevalence and diversity of gastrointestinal(GI) symptoms in patients undergoing peritoneal dialysis(PD) and hemodialysis(HD).METHODS: Two hundred and ninety-four end-stage renal disease patients participated in the study, including 182 HD and 112 PD patients. Dimension scores were calculated from a modified gastrointestinal symptom rating scale(GSRS) 18-item questionnaire, including items concerning eating dysfunction, and were used for measuring GI symptoms. Information on patient age, condition contributing to end-stage renal disease and the most recent dialysis adequacy assessment(serum Kt/V urea value) was obtained from the follow-up database and by interviewing patients and/or reviewing the medical records. Differences between the HD and PD groups were evaluated using Student's t, Pearson's χ2 or Fisher's exact tests.RESULTS: The overall prevalence of GI symptoms,defined by a GSRS > 1, in end-stage renal disease patients was 70.7%(208/294), which differed between HD and PD patients(76.4% vs 61.6%, P < 0.01). HD patients had a higher prevalence of constipation, abdominal pain and diarrhea compared to PD patients(36.3% vs 17.9%, 32.4% vs 5.4%, 17.6% vs 4.5%, respectively, P < 0.05). PD patients had a higher prevalence of reflux compared to HD patients(32.1% vs 24.2%, P < 0.05). Additionally, reflux and eating dysfunction were more severe in PD patients(GSRS: 1.71 ± 1.15 vs 1.30 ± 0.67, 1.57 ± 0.84 vs 1.39 ± 0.61, respectively, P < 0.05), whereas HD patients had greater abdominal pain, diarrhea and constipation(GSRS: 1.22 ± 0.39 vs 1.04 ± 0.19, 1.19 ± 0.53 vs 1.07 ± 0.35, 1.51 ± 0.83 vs 1.23 ± 0.58, respectively, P < 0.05). Finally, 14.8%(27/182) of HD patients presented with more than three GI symptoms, compared to 7.2%(8/112) of PD patients(P < 0.01).CONCLUSION: HD and PD patients differ in prevalence, severity and diversity of GI symptoms.Rui Dong Zhi-Yong Guo Jia-Rong Ding Yang-Yang Zhou Hao Wu 2014World Journal of Gastroenterology2014,20,32:20
13Association of platelet to lymphocyte ratio with in-hospital major adverse cardiovascular events and the severity of coronary artery disease assessed by the Gensini score in patients with acute myocardial infarction显示文摘Background:The platelet to lymphocyte ratio(PLR)has recently emerged as a potential inflammatory biomarker and has been shown to be significantly associated with atherosclerotic coronary artery disease(CAD).Therefore,we aimed to explore the association of PLR with in-hospital major adverse cardiovascular events(MACEs)and the severity of CAD assessed by the Gensini score(GS)in patients with acute myocardial infarction(AMI)undergoing coronary angiography.Methods:A total of 502 patients with AMI consecutively treated at the Affiliated Hospital of Qingdao University(Qingdao,China)and underwent coronary angiography from August 2017 to December 2018 were recruited in this study.The demographic,clinical,angiographic characteristics,and laboratory parameters were collected.According to the presence of in-hospital MACEs,the included patients were divided into the MACE group(n=81)and the non-MACE group(n=421).Further,according to tertiles of the GS,the patients were classified into three groups:the low GS group(GS≤32 points,n=173),medium GS group(32 pointsXue-Ting Li Hao Fang Dong Li Feng-Qiang Xu Bin Yang Rui Zhang Yi An 2020Chinese Medical Journal2020,,4:19

15Microwave Exposure Impairs Synaptic Plasticity in the Rat Hippocampus and PC12 Cells through Over-activation of the NMDA Receptor Signaling Pathway显示文摘Objective The aim of this study is to investigate whether microwave exposure would affect the N-methyl-D-aspartate receptor(NMDAR) signaling pathway to establish whether this plays a role in synaptic plasticity impairment. Methods 48 male Wistar rats were exposed to 30 m W/cm2 microwave for 10 min every other day for three times. Hippocampal structure was observed through H&E staining and transmission electron microscope. PC12 cells were exposed to 30 m W/cm2 microwave for 5 min and the synapse morphology was visualized with scanning electron microscope and atomic force microscope. The release of amino acid neurotransmitters and calcium influx were detected. The expressions of several key NMDAR signaling molecules were evaluated. Results Microwave exposure caused injury in rat hippocampal structure and PC12 cells, especially the structure and quantity of synapses. The ratio of glutamic acid and gamma-aminobutyric acid neurotransmitters was increased and the intracellular calcium level was elevated in PC12 cells. A significant change in NMDAR subunits(NR1, NR2 A, and NR2B) and related signaling molecules(Ca2+/calmodulin-dependent kinase II gamma and phosphorylated c AMP-response element binding protein) were examined. Conclusion 30 m W/cm2 microwave exposure resulted in alterations of synaptic structure, amino acid neurotransmitter release and calcium influx. NMDAR signaling molecules were closely associated with impaired synaptic plasticity.XIONG Lu SUN Cheng Feng ZHANG Jing GAO Ya Bing WANG Li Feng ZUO Hong Yan WANG Shui Ming ZHOU Hong Mei XU Xin Ping DONG Ji YAO Bin Wei ZHAO Li PENG Rui Yun 2015Biomedical and Environmental Sciences2015,28,1:16
16Two surgical procedures for esophagogastric variceal bleeding in patients with portal hypertension显示文摘AIM:To determine the clinical value of a splenorenal shunt plus pericardial devascularization(PCVD)in portal hypertension(PHT)patients with variceal bleeding.METHODS:From January 2008 to November 2012,290 patients with cirrhotic portal hypertension were treated surgically in our department for the prevention of gastroesophageal variceal bleeding:207 patients received a routine PCVD procedure(PCVD group),and83 patients received a PCVD plus a splenorenal shunt procedure(combined group).Changes in hemodynamic parameters,rebleeding,encephalopathy,portal vein thrombosis,and mortality were analyzed.RESULTS:The free portal pressure decreased to 21.43±4.35 mmHg in the combined group compared with24.61±5.42 mmHg in the PCVD group(P<0.05).The changes in hemodynamic parameters were more significant in the combined group(P<0.05).The long-term rebleeding rate was 7.22%in the combined group,which was lower than that in the PCVD group(14.93%),(P<0.05).CONCLUSION:Devascularization plus splenorenal shunt is an effective and safe strategy to control esophagogastric variceal bleeding in PHT.It should be recommended as a first-line treatment for preventing bleeding in PHT patients when surgical interventions are considered.Lin Yang Li-Juan Yuan Rui Dong Ji-Kai Yin Qing Wang Tao Li Jiang-Bin Li Xi-Lin Du Jian-Guo Lu 2013World Journal of Gastroenterology2013,19,48:15
17Liquefaction macrophenomena in the great Wenchuan earthquake显示文摘On May 12,2008 at 14:28,a catastrophic magnitude Ms 8.0 earthquake struck the Sichuan Province of China.The epicenter was located at Wenchuan(31.00oN,103.40oE).Liquefaction macrophenomena and corresponding destruction was observed throughout a vast area of 500 km long and 200 km wide following the earthquake.This paper illustrates the geographic distribution of the liquefaction and the relationship between liquefaction behavior and seismic intensity,and summarizes the liquefaction macrophenomena,including sandboils and waterspouts,ground subsidence,ground fi ssures etc.,and relevant liquefaction features.A brief summary of the structural damage caused by liquefaction is presented and discussed.Based on comparisons with liquefaction phenomena observed in the 1976 Tangshan and 1975 Haicheng earthquakes,preliminary analyses were performed,which revealed some new features of liquefaction behavior and associated issues arising from this event.The site investigation indicated that the spatial non-uniformity of liquefaction distribution was obvious and most of the liquefi ed sites were located in regions of seismic intensity VIII.However,liquefaction phenomena at ten different sites in regions of seismic intensity VI were also observed for the fi rst time in China mainland.Sandboils and waterspouts ranged from centimeters to tens of meters,with most between 1 m to 3 m.Dramatically high water/sand ejections,e.g.,more than 10 m,were observed at four different sites.The sand ejections included silty sand,fi ne sand,medium sand,course sand and gravel,but the ejected sand amount was less than that in the 1976 Tangshan earthquake.Possible liquefaction of natural gravel soils was observed for the fi rst time in China mainland.Chen Longwei Yuan Xiaoming Cao Zhenzhong Hou Longqing Sun Rui Dong Lin Wang Weiming Meng Fanchao Chen Hongjuan 2009Earthquake Engineering and Engineering Vibration2009,8,2:14
18Molecular cloning and functional analysis of the FLOWERING LOCUS T(FT) homolog Gh FT1 from Gossypium hirsutum显示文摘FLOWERING LOCUS T(FT) encodes a member of the phosphatidylethanolamine-binding protein(PEBP) family that functions as the mobile floral signal, playing an important role in regulating the floral transition in angiosperms. We isolated an FT-homolog(Gh FT1) from Gossypium hirsutum L. cultivar,Xinluzao 33 Gh FT1 was predominantly expressed in stamens and sepals, and had a relatively higher expression level during the initiation stage of fiber development. Gh FT1 m RNA displayed diurnal oscillations in both long-day and short-day condition,suggesting that the expression of this gene may be under the control of the circadian clock. Subcellular analysis revealed that Gh FT1 protein located in the cytoplasm and nucleus. Ectopic expression of Gh FT1 in transgenic arabidopsis plants resulted in early flowering compared with wild-type plants. In addition,ectopic expression of Gh FT1 in arabidopsis ft-10 mutants partially rescued the extremely late flowering phenotype. Finally, several Researchflowering related genes functioning downstream of At FT were highly upregulated in the 35S::Gh FT1 transgenic arabidopsis plants. In summary, Gh FT1 is an FT-homologous gene in cotton that regulates flower transition similar to its orthologs in other plant species and thus it may be a candidate target for promoting early maturation in cotton breeding.Danli Guo Chao Li Rui Dong Xiaobo Li Xiangwen Xiao Xianzhong Huang 2015Journal of Integrative Plant Biology2015,57,6:14

20Real-time transient stability assessment in power system based on improved SVM显示文摘Due to the strict requirements of extremely high accuracy and fast computational speed, real-time transient stability assessment(TSA) has always been a tough problem in power system analysis.Fortunately, the development of artificial intelligence and big data technologies provide the new prospective methods to this issue, and there have been some successful trials on using intelligent method, such as support vector machine(SVM) method.However, the traditional SVM method cannot avoid false classification, and the interpretability of the results needs to be strengthened and clear.This paper proposes a new strategy to solve the shortcomings of traditional SVM,which can improve the interpretability of results, and avoid the problem of false alarms and missed alarms.In this strategy, two improved SVMs, which are called aggressive support vector machine(ASVM) and conservative support vector machine(CSVM), are proposed to improve the accuracy of the classification.And two improved SVMs can ensure the stability or instability of the power system in most cases.For the small amount of cases with undetermined stability, a new concept of grey region(GR) is built to measure the uncertainty of the results, and GR can assessment the instable probability of the power system.Cases studies on IEEE 39-bus system and realistic provincial power grid illustrate the effectiveness and practicability of the proposed strategy.Wei HU Zongxiang LU Shuang WU Weiling ZHANG Yu DONG Rui YU Baisi LIU 2019Journal of Modern Power Systems and Clean Energy2019,7,1:14
