| 1 | Reliability Evaluation of Electricity-heat Integrated Energy System with Heat Pump显示文摘Integrated energy system(IES)has the advantages of improving the efficiency of energy utilization and promoting the consumption of renewable energy.It is of great importance to evaluate the reliability of an IES.This paper proposes a novel reliability evaluation method for the electricity-heat IES with heat pump.First,the load-point reliability indices and systemlevel reliability indices are defined according to the characteristics of electricity-heat IES.Second,the model of maximum output heat power of heat pump at the user-side considering the safety criterion of distribution network is established,and the stepvaried repeated power flow method is applied to solve the model.Third,the reliability evaluation procedure of electricityheat IES with heat pump based on the Monte Carlo simulation is presented.Case studies are carried out on the electricityheat IES of an industrial park,and the results show that the configuration site,capacity and coefficient of performance of heat pump as well as the security constraints of distribution network can significantly affect the reliability indices. | Shenxi Zhang Min Wen Haozhong Cheng Xiao Hu Guodong Xu | 2018 | CSEE Journal of Power and Energy Systems2018，4，4： | 7 |
| 2 | A Survey of Bitmap Index Compression Algorithms for Big Data显示文摘With the growing popularity of Internet applications and the widespread use of mobile Internet, Internet traffic has maintained rapid growth over the past two decades. Internet Traffic Archival Systems(ITAS) for packets or flow records have become more and more widely used in network monitoring, network troubleshooting, and user behavior and experience analysis. Among the three key technologies in ITAS, we focus on bitmap index compression algorithm and give a detailed survey in this paper. The current state-of-the-art bitmap index encoding schemes include: BBC, WAH, PLWAH, EWAH, PWAH, CONCISE, COMPAX, VLC, DF-WAH, and VAL-WAH. Based on differences in segmentation, chunking, merge compress, and Near Identical(NI) features, we provide a thorough categorization of the state-of-the-art bitmap index compression algorithms. We also propose some new bitmap index encoding algorithms, such as SECOMPAX, ICX, MASC, and PLWAH+, and present the state diagrams for their encoding algorithms. We then evaluate their CPU and GPU implementations with a real Internet trace from CAIDA. Finally, we summarize and discuss the future direction of bitmap index compression algorithms. Beyond the application in network security and network forensic, bitmap index compression with faster bitwise-logical operations and reduced search space is widely used in analysis in genome data, geographical information system, graph databases, image retrieval, Internet of things, etc. It is expected that bitmap index compression will thrive and be prosperous again in Big Data era since 1980s. | Zhen Chen Yuhao Wen Junwei Cao Wenxun Zheng Jiahui Chang Yinjun Wu Ge Ma Mourad Hakmaoui Guodong Peng | 2015 | Tsinghua Science and Technology2015，20，1： | 5 |

| 4 | Isolation of a strong matrix attachment region (MAR) and identification of its function in vitro and in vivo显示文摘Inclusion of MARs in transgene cassettes enhances their expression and reduces position-effect variations in the transgenic host. Four new MARs (TM2, TM3, AM1 and AM2) were isolated from tobacco and Arabidopsis by PCR method. The nuclei isolated from suspension-cultured cells of rice were used to prepare nuclear matrix. With a characterized MAR (TM1) as a positive control, the Matrix-MAR interactions were tested by an in vitro binding assay to identify the DNA sequences as MARs and their binding strength to nuclear matrix in vitro was compared. The results showed that TM2 and TM3 had stronger binding strength than TM1. To determine the functions of the four new MARs in vivo, binary vectors pBI121 carrying a uidA GUS reporter gene were modified with direct repeat MARs inserted on both sides of the reporter gene cassette and were transferred into tobaccos via Agrobacterium-mediated transformation procedure. Quantitative GUS assays of the transgenic tobaccos showed that when flanking a GUS reporter gene | Kewei Zhang Jianmei Wang Guodong Yang Xingqi Guo Fujiang Wen Decai Cui Chengchao Zheng | 2002 | Chinese Science Bulletin2002，47，23： | 2 |
| 5 | Analysis of Propagation Characteristics of Electromagnetic Disturbance from the Off-Line of Pantograph-Catenary in High-Speed Railway Viaducts显示文摘Pantograph arcing caused by Off-line of pan to graph-ca tenary(OLPC)will generate Electromagnetic disturbance(EMD),which will aflfect train control system and communication system.This paper proposes a simplified model of the train and pantograph to investigate propagation characteristics of EMD from OLPC in the viaduct scenario,containing attenuation law in transverse and longi tu dinal direc tio ns.As a resul t,the elec trie field st reng th of EMD from OLPC increases with distance in transverse direction from 10m to 30m in the viaduct scenario,which is different from the ground scenario.The fitting formulas are found to research the attenuation law at different frequency points.We get the conclusion that the limit and measurement distance is not applicable for the viaduct scenario in current standard.To prove this,measurement in the viaduct scenario is completed,and the plausible evidence to explain the result is discussed.These results are useful in the measurement of radiated emissions,on-board equipment layout and the research of standard in high-speed railway. | LI Meng WEN Yinghong SUN Xiaokang WANG Guodong | 2020 | Chinese Journal of Electronics2020，29，5： | 2 |

| 8 | Recent progress of carbon-based metal-free materials in thermal-driven catalysis显示文摘The carbon-based metal-free materials as catalysts(named as carbocatalysts) have been attracting tremendous attentions in electric-,solar-and thermal-driven reactions nowadays.Compared to electrocatalysis and photocatalysis,the thermal-driven catalysis(thermocatalysis) including liquid phase and gas phase reactions involves wider scope and is relatively easy to realize practical large-scale applications.Over the past several years,some striking achievements on the design of new carbon-based metal-free materials with well-defined structures and heteroatom groups as well as the revelation of new reaction mechanisms and active sites in thermocatalysis have been obtained.However,comparative discussions regarding these recent achievements have been rarely highlighted.In this review,we systematically summarize and discuss six kinds of carbocatalysts and their applications in thermocatalysis.These materials include typical oxygen-attached carbon,surface modified carbon(graft with certain organic compounds),mono-doped carbon,co-doped carbon,carbon nitride and materials with carbon as dopant.Some new reaction processes as well as the related reaction mechanisms,active sites and intermediates are reviewed critically.Moreover,an outlook on the in-depth investigation of the metalfree carbocatalysis in the future is provided. | Shuchang Wu Linhui Yu Guodong Wen Zailai Xie Yangming Lin | 2021 | Journal of Energy Chemistry2021，30，7： | 1 |

| 11 | Palladium and carbon synergistically catalyzed room-temperature hydrodeoxygenation(HDO) of vanillyl alcohol–A typical lignin model molecule显示文摘Vanillyl alcohol,which is made up of an aromatic ring,an alcoholic hydroxyl group,a phenolic hydroxyl group and a methoxy group,was selected as the model molecule of lignin.Various carbon materials supported Pd catalysts were chosen to catalyze the HDO of vanillyl alcohol.The catalysts were characterized via TEM,TPD,XRD,XPS and CO-chemisorption.It was found that different carbon materials could obviously influence the particle sizes,dispersion and distribution of Pd or Pd O particles.Palladium and carbon can synergistically catalyze the room-temperature HDO of vanillyl alcohol even at room temperature,and the carboxyl group was found to be the effective active acid site during the reaction.Possible reaction mechanism was also proposed.The existence of the effective active acid sites on the carbon supports could obviously lower the reaction temperature without decreasing the selectivity,as a result,making the production of renewable fuels by HDO much more economically feasible,which is of much importance. | Qi Wang Neeraj Gupta Guodong Wen Sharifah Bee Abd Hamid Dang Sheng Su | 2017 | Journal of Energy Chemistry2017，26，1： | 1 |

| 14 | Separation of Pd and Pt from highly acidic leach liquor of spent automobile catalysts with monothio-Cyanex 272 and trioctylamine显示文摘Platinum group metals(PGMs),especially Pd,Pt,and Rh,have drawn great attention due to their unique features.Direct separation of Pd and Pt from highly acidic automobile catalyst leach liquors is disturbed by various factors.This work investigates the effect of various parameters including the acidity,extractant concentration,phase ratio A/O,and diluents on the Pd and Pt extraction and their stripping behaviors.The results show that the Pd and Pt are successfully separated from simulated leach liquor of spent automobile catalysts with monothioCyanex 272 and trioctylamine(TOA).Monothio-Cyanex 272 shows strong extractability and specific selectivity for Pd,and only one single stage is needed to recover more than 99.9% of Pd,leaving behind all the Pt,Rh,and base metals of Fe,Mg,Ce,Ni,Cu,and Co in the raffinate.The loaded Pd is efficiently stripped by acidic thiourea solutions.TOA shows strong extractability for Pt and Fe at acidity of 6 mol·L^(–1) HCl.More than 99.9% of Pt and all of the Fe are extracted into the organic phase after two stages of countercurrent extraction.Diluted HCl easily scrubs the loaded base metals(Fe,Cu,and Co).The loaded Pt is efficiently stripped by 1.0 mol·L^(–1) thiourea and 0.05–0.1 mol·L^(–1) Na OH solutions.Monothio-Cyanex 272 and TOA can realize the separation of Pd and Pt from highly acidic leach liquor of spent automobile catalysts. | Junlian Wang Lu Liu Wen Xu Hui Liu Guodong Xu Kun Huang Fengshan Yu Guoyong Huang | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，5： | 1 |

| 17 | The role ofβ,γ,δ-substituent of dialkylphosphinic acids in HREE extraction and separation behaviors显示文摘Heavy rare earth element(HREE)separation has always been a great challenge.The kind of dialkylphosphinic acids is recognized as the third generation of organophosphorous acid extractants.However,detailed relationship betweenβ-substituent(especially when it changes from H to methyl,and further to ethyl)and their extraction behaviors and selectivity for HREEs have rarely been reported.Besides,there are also few reports on effect ofγ,δ-substituent on HREE extraction and separation.In this paper,we synthesized five and collected two dialkylphosphinic acids with differentβ,γ,δ-substituents(from H to ethyl).These extractants were divided into two groups to discuss their extraction behaviors and selectivity for HREEs:β-substituent group(P208,INET-1,P218,USTB-1 and P227)andγ,δ-substituent group(P218,P2132 and Cyanex 272).To evaluate and compare their extractabilities,P507 was used as a reference and Tm,Yb,Lu were extracted with 0.01 mol/L of these extractants from single Tm,Yb and Lu solutions(~4×10^(-4)mol/L)at different initial pH.Besides,pH_(0.5)(Tm),pH_(0.5)^(Yb)and pH_(0.5)^(Lu)values and their differences(ΔpH_(0.5)^(Tm-Yb),ΔpH_(0.5)^(Yb-Lu),ΔpH_(0.5)^(Tm-Lu))for each extractant were given to roughly evaluate their separation performance for Tm,Yb and Lu.To further investigate the selectivity of these extractants for HREEs,Tb,Dy,Ho,Er,Tm,Yb and Lu were extracted from their mixed solution with initial pH of 4.00 at phase ratio A/O of 2:1,1:1 or 1:2.Their HREE separation performance is mainly discussed based on the adjacent HREE separation factors(β_(N+1/N))and their average value(β_(Tb-Lu)). | Junlian Wang Wen Xu Jianguo Cui Guodong Xu Yufu Chen Peilong Wang Ziyong Chang | 2023 | Journal of Rare Earths2023，41，11： | 1 |
| 18 | Carbon and nitrogen budget in fish-polychaete integrated aquaculture system显示文摘Integrated multi-tropic aquaculture(IMTA)systems have been used in China for many years and have achieved significant economic,social,and ecological benefits.However,there is still a lack of benthic bioremediation species that can effectively utilize the aquaculture particulate organic waste in the system.Polychaete Perinereis aibuhitensis Grube is used as an environmental remediation species for large-scale aquaculture to reduce particulate organic waste,which is of great significance to environmental protection.To improve bio-elements utilization efficiency,P.aibuhitensis was applied for IMTA indoor fish(Hexagrammos otakii)farming.Results showed that in the system,production of 1 kg of the fish discharged 2141-2338 mg of carbon and 529-532 mg of nitrogen,while in the monoculture of the fish,the figures were 3033-3390 mg and 764-794 mg,or 24.84%-35.26%and 30.35%-33.32%less,respectively.This approach promoted IMTA technology that could utilize the particulate organic waste from intensive aquaculture and reduce the adverse environmental effects. | Fawen HU Ming SUN Jinghui FANG Guodong WANG Li LI Fengxiang GAO Yuxia JIAN Xue WANG Guangbin LIU Yan ZOU Wen GUO | 2021 | Journal of Oceanology and Limnology2021，39，3： | 1 |

| 20 | Effect of pre-treatments on drying characteristics of Chinese jujube (Zizyphus jujuba Miller)显示文摘Chinese jujube is delicious and nourishing fruit.However,fresh Chinese jujube is liable to rot and drying is a necessary process.Traditional drying is a time-consuming task due to the thick cuticle of Chinese jujube.To improve its drying efficiency,fresh Chinese jujube was pretreated with nine different methods prior to hot-air drying.Among these methods,dipping in 2%ethyl oleate plus 5%K_(2)CO_(3) for 10 min(alkaline emulsion of ethyl oleate,AEEO)was recommended for its time-saving effect,which was found more significant at lower drying temperatures.The beneficial effect was considered based on its cuticle destruction by AEEO pre-treatment.In the meantime,the drying process was divided into three stages;each of them obeyed the first order reaction kinetics.Activation energies for the first,second and third stages of control over jujube drying were 41.45 kJ/mol,35.24 kJ/mol and 49.52 kJ/mol,and reduced by 20.9%,22.1%and 29.0%,respectively,after AEEO pre-treatment,and the drying process was well predicted by Midilli et al.model.In view of browning during drying at higher temperatures,AEEO pretreated jujube was suggested to be dried at 60°C.This finding was considered to be helpful to the industrial drying of Chinese jujube. | Zhu Baomeng Wen Xuesen Wei Guodong | 2014 | International Journal of Agricultural and Biological Engineering2014，7，1： | 1 |
