| 3 | Effects of closing and reopening live poultry markets on the epidemic of human infection with avian influenza A virus显示文摘Live poultry markets(LPMs) are crucial places for human infection of influenza A(H7N9 virus).In Yangtze River Delta,LPMs were closed after the outbreak of human infection with avian influenza A(H7N9) virus,and then reopened when no case was found.Our purpose was to quantify the effect of LPMs' operations in this region on the transmission of influenza A(H7N9) virus.We obtained information about dates of symptom onset and locations for all human influenza A(H7N9) cases reported from Shanghai,Jiangsu and Zhejiang provinces by May 31,2014,and acquired dates of closures and reopening of LPMs from official media.A two-phase Bayesian model was fitted by Markov Chain Monte Carlo methods to process the spatial and temporal influence of human cases.A total of 235 cases of influenza A(H7N9) were confirmed in Shanghai,Jiangsu and Zhejiang by May 31,2014.Using these data,our analysis showed that,after LPM closures,the influenza A(H7N9) outbreak disappeared within two weeks in Shanghai,one week in Jiangsu,and one week in Zhejiang,respectively.Local authorities reopened LPMs when there was no outbreak of influenza A(H7N9),which did not lead to reemergence of human influenza A(H7N9).LPM closures were effective in controlling the H7N9 outbreak.Reopening of LPM in summer did not increase the risk of human infection with H7N9.Our findings showed that LPMs should be closed immediately in areas where the H7N9 virus is confirmed in LPM.When there is no outbreak of H7N9 virus,LPMs can be reopened to satisfy the Chinese traditional culture of buying live poultry.In the long term,local authorities should take a cautious attitude in permanent LPM closure. | Jian Lu Wendong Liu Rui Xia Qigang Dai Changjun Bao Fenyang Tang Yefei Zhu Qiao Wang | 2016 | The Journal of Biomedical Research2016，30，2： | 7 |
| 4 | New innovations in pavement materials and engineering:A review on pavement engineering research 2021显示文摘Sustainable and resilient pavement infrastructure is critical for current economic and environmental challenges.In the past 10 years,the pavement infrastructure strongly supports the rapid development of the global social economy.New theories,new methods,new technologies and new materials related to pavement engineering are emerging.Deterioration of pavement infrastructure is a typical multi-physics problem.Because of actual coupled behaviors of traffic and environmental conditions,predictions of pavement service life become more and more complicated and require a deep knowledge of pavement material analysis.In order to summarize the current and determine the future research of pavement engineering,Journal of Traffic and Transportation Engineering(English Edition)has launched a review paper on the topic of'New innovations in pavement materials and engineering:A review on pavement engineering research 2021'.Based on the joint-effort of 43 scholars from 24 well-known universities in highway engineering,this review paper systematically analyzes the research status and future development direction of 5 major fields of pavement engineering in the world.The content includes asphalt binder performance and modeling,mixture performance and modeling of pavement materials,multi-scale mechanics,green and sustainable pavement,and intelligent pavement.Overall,this review paper is able to provide references and insights for researchers and engineers in the field of pavement engineering. | JTTE Editorial Office Jiaqi Chen Hancheng Dan Yongjie Ding Yangming Gao Meng Guo Shuaicheng Guo Bingye Han Bin Hong Yue Hou Chichun Hu Jing Hu Ju Huyan Jiwang Jiang Wei Jiang Cheng Li Pengfei Liu Yu Liu Zhuangzhuang Liu Guoyang Lu Jian Ouyang Xin Qu Dongya Ren Chao Wang Chaohui Wang Dawei Wang Di Wang Hainian Wang Haopeng Wang Yue Xiao Chao Xing Huining Xu Yu Yan Xu Yang Lingyun You Zhanping You Bin Yu Huayang Yu Huanan Yu Henglong Zhang Jizhe Zhang Changhong Zhou Changjun Zhou Xingyi Zhu | 2021 | Journal of Traffic and Transportation Engineering(English Edition)2021，8，6： | 7 |
| 5 | The CO_2 absorption and desorption performance of the triethylenetetramine + N,N-diethylethanolamine + H_2O system显示文摘Post-combustion CO_2 capture(PCC) process faces significant challenge of high regeneration energy consumption.Biphasic absorbent is a promising alternative candidate which could significantly reduce the regeneration energy consumption because only the CO_2-concentrated phase should be regenerated. In this work, aqueous solutions of triethylenetetramine(TETA) and N,N-diethylethanolamine(DEEA) are found to be efficient biphasic absorbents of CO_2. The effects of the solvent composition, total amine concentration, and temperature on the absorption behavior, as well as the effect of temperature on the desorption behavior of TETA–DEEA–H2 O system were investigated. An aqueous solution of 1 mol·L-1 TETA and 4 mol·L-1 DEEA spontaneously separates into two liquid phases after a certain amount of CO_2 is absorbed and it shows high CO_2 absorption/desorption performance.About 99.4% of the absorbed CO_2 is found in the lower phase, which corresponds to a CO_2 absorption capacity of 3.44 mol·kg-1. The appropriate absorption and desorption temperatures are found to be 30 °C and 90 °C,respectively. The thermal analysis indicates that the heat of absorption of the 1 mol·L-1 TETA and 4 mol·L-1 DEEA solution is-84.38 kJ·(mol CO_2)-1 which is 6.92 kJ·(mol CO_2)-1 less than that of aqueous MEA. The reaction heat, sensible heat, and the vaporization heat of the TETA–DEEA–H2 O system are lower than that of the aqueous MEA, while its CO_2 capacity is higher. Thus the TETA–DEEA–H2 O system is potentially a better absorbent for the post-combustion CO_2 capture process. | Yaoyao Li Changjun Liu Richard Parnas Yingying Liu Bin Liang Houfang Lu | 2018 | Chinese Journal of Chemical Engineering2018，26，11： | 6 |

| 7 | A single mutation in the PBC loop of VP2 is involved in the in vitro replication of infectious bursal disease virus显示文摘To test whether amino acid mutations in the PBC and PHI loops of VP2 are involved in the replication and virulence of infectious bursal disease virus(IBDV), a pair of viruses, namely the moderately virulent IBDV(rG x-F9VP2) and the attenuated strain(rGt), were used. Residue mutations A222P(P_(BC)) and S330R(PHI), selected by sequence comparison, were introduced individually into r Gx-F9VP2 by using a reverse genetics system. In addition, the reverse mutation of either P222 A or R330 S was introduced into r Gt. The four modified viruses were then rescued and evaluated in vitro(CEF cells) and in vivo(SPF chickens). Results showed that A222 P elevated the replication efficiency of rG x-F9VP2 while P222 A reduced that of rG t in CEF cells. A mutation at residue 330 did not alter IBDV replication. In addition, animal experiments showed that a single mutation at either residue 222 or 330 did not significantly influence the virulence of IBDV. In conclusion, residue 222 in PBC of VP2 is involved in the replication efficiency of IBDV in vitro but does not affect its virulence in vivo, further facilitating our understanding of the gene-function of IBDV. | Xiaole Qi Xiang Gao Zhen Lu Lizhou Zhang Yongqiang Wang Li Gao Yulong Gao Kai Li Honglei Gao Changjun Liu Hongyu Cui Yanping Zhanga Xiaomei Wang | 2016 | Science China(Life Sciences)2016，59，7： | 2 |

| 10 | Preparation and water sorption properties of novel SiO_(2)-LiBr microcapsules for water-retaining pavement显示文摘Novel SiO_(2)-LiBr microcapsules for water-retaining pavement were prepared and firstly characterized by scanning electron microscope(SEM),particle size analysis,and Fourier transform infrared spectroscopy(FT-IR).The water vapor sorption and desorption of the formulated microcapsules was then experimentally studied using dynamic vapor sorption(DVS),with the results fitted to three kinds of adsorption kinetics models.In addition,the specific surface area(SSA)was also calculated based on BET theory;and the thermal performance was investigated by laser flash analysis(LFA).Experimental results show a change of 103%in mass of the microcapsule sample under 90%relative humidity(RH)at 30℃after water vapor sorption.The fitting of results indicates that the adsorption process is mainly governed by the intra-particle diffusion mechanism,followed by the pseudo-first-order adsorption process.In comparison with most conventional pavement materials,it is found that the SSA of the formulated microcapsules is much larger while the thermal conductivity is lower.The unique properties of the formulated SiO_(2)-LiBr microcapsules have significant potential to take the edge off the urban heat island effect and reduce rutting when applied to water-retaining pavement materials. | Wenjing Li Gilmore Wellio Tiejun Lu Changjun Zou Yongliang Li | 2021 | Chinese Journal of Chemical Engineering2021，34，6： | 1 |
| 11 | Strategy evaluation and optimization with an artificial society toward a Pareto optimum显示文摘Strategy evaluation and optimization in response to troubling urban issues has become a challenging issue due to increasing social uncertainty,unreliable predictions,and poor decision-making.To address this problem,we propose a universal computational experiment framework with a fine-grained artificial society that is integrated with data-based models.The purpose of the framework is to evaluate the consequences of various combinations of strategies geared towards reaching a Pareto optimum with regards to efficacy versus costs.As an example,by modeling coronavirus disease 2019 mitigation,we show that Pareto frontier nations could achieve better economic growth and more effective epidemic control through the analysis of real-world data.Our work suggests that a nation’s intervention strategy could be optimized based on the measures adopted by Pareto frontier nations through large-scale computational experiments.Our solution has been validated for epidemic control,and it can be generalized to other urban issues as well. | Zhengqiu Zhu Bin Chen Hailiang Chen Sihang Qiu Changjun Fan Yong Zhao Runkang Guo Chuan Ai Zhong Liu Zhiming Zhao Liqun Fang Xin Lu | 2022 | The Innovation2022，3，5： | 1 |

| 13 | The quasi-activity coefficients of non-electrolytes in aqueous solution with organic ions and its application on the phase splitting behaviors prediction for CO_(2) absorption显示文摘CO_(2)capture with a low energy consumption is of important application significance for reducing CO_(2)emission.The phase-change absorbent developed in recent years shows its potential for low-energy CO_(2)capture.The unclear phase-splitting rule hinders the efficient development of CO_(2)phase-change absorbents.To predict phase-splitting behaviors of mono/poly-amine-organic solvent-water system with various concentrations,a quasi-activity coefficient was developed based on Debye&Mc Aulay equation and some Density function theory descriptors.Six models based on Debye&Mc Aulay equation were developed with different ion radius,descriptors or poly-amine-CO_(2)products.The phase-splitting boundary was drawn on the model with the best predictability.This quasi-activity coefficient would provide guidance for the phase-splitting systems development,especially for polyamines. | Xiaomeng Zhao Xingyu Li Changjun Liu Shan Zhong Houfang Lu Hairong Yue Kui Ma Lei Song Siyang Tang Bin Liang | 2022 | Chinese Journal of Chemical Engineering2022，35，3： | 1 |

| 15 | Production of glycerol carbonate using crude glycerol from biodiesel production with DBU as a catalyst显示文摘The biodiesel production technology catalyzed by 1,8-diazabicycloundec-7-ene(DBU)is developed in this work.Crude glycerol containing DBU and DBU/glycerol/CO_2(DGC)ionic compounds reacts directly with dimethyl carbonate(DMC)to produce high value-added glycerol carbonate(GC)catalyzed by DBU and DGC.The catalytic performance of DBU and DGC,as well as the kinetics of the reaction catalyzed by DBU,were investigated.The results show that DGC has a weak catalytic effect on the transesterification of glycerol and DMC.When the temperature is higher than 60°C,DGC catalyzes the reaction jointly with DBU,which is produced from the decomposition of DGC.DBU has a good catalytic effect on the reaction between glycerol and DMC,with 90%conversion of glycerol and 84%selectivity to GC under the following conditions:DMC-to-glycerol molar ratio of 3:1,4.0%DBU(based on glycerol mass),reaction time of 60 min,and reaction temperature of 40°C.The apparent kinetics results show that the activation energies are 30.95 kJ·mol^(-1)and 55.16 kJ·mol^(-1)for the forward and reverse GC generation reactions,respectively,and the activation energy of the decomposition reaction of GC to glycidol(GD)is 26.58 kJ·mol^(-1). | Ying Qing Houfang Lu Yingying Liu Changjun Liu Bin Liang Wei Jiang | 2018 | Chinese Journal of Chemical Engineering2018，26，9： | 0 |
| 16 | Effect of Tongxinluo on basic fibroblast growth factor mRNA after cerebral ischemia/reperfusion injury显示文摘BACKGROUND: Basic fibroblast growth factor (bFGF) can cause proliferation and differentiation of plentiful cells which are derived from mesoblast and neural ectoblast. Previous researches suggested that Tongxinluo could promote differentiation from neural stem cells (NSCs) to neurons and astrocytes after cerebral ischemia/reperfusion injury. OBJECTIVE: To observe the effect of Tongxinluo on bFGF mRNA of rats after cerebral ischemia/reperfusion injury and analyze its dosage-dependence. DESIGN: Randomized controlled study. SETTING: Department of Neurology, Nanfang Hospital of Southern Medical University. MATERIALS: The experiment was carried out in Neurological Department of Nanfang Hospital affiliated to Southern Medical University from May 2005 to March 2006. A total of 192 healthy Wistar rats, weighing (200±20) g, of SPF grade, of both gender by half, were provided by Experimental Animal Center of Nanfang Hospital Affiliated to Southern Medical University. Tongxinluo was consisted of renshen, wugong, quanxie, shuizhi, chishao, bingpian, etc. and was provided by Shijiazhuang Yiling Pharmaceutical Co., Ltd. (batch number: 9906115). Main reagents: Agarose, DEPC-treated water, total RNA purification kit and one-step reverse transcription polymerase chain reaction (RT-PCR) kit were provided by Beijing Saibaisheng Gene Technique Co., Ltd. METHODS: All rats were randomly divided into 4 groups, including high-dosage Tongxinluo group, low-dosage Tongxinluo group, model group and sham operation group with 48 in each group. Rats in the former three groups were observed at 3, 5, 7, 14, 21 and 30 days after ischemia/reperfusion. In addition, rats in sham operation group were selected at the relevant time points. Every 8 rats were selected from each group for once. ① Right middle cerebral artery occlusion-reperfusion models were induced by Koizumi method and modified; moreover, neurological impairment was evaluated with Zealonga method. Except rats in sham operation group, rats in other three groups were involved in the final analysis, if scores of neurological impairment were higher than 2 at 6 hours after modeling. ② Administration: Rats in high-dosage Tongxinluo group were perfused with 150 g/L 1 g/(kg·d) Tongxinluo suspension; rats in low-dosage Tongxinluo group were perfused with 75 g/L 0.5 g/(kg·d) Tongxinluo suspension; rats in sham operation group and control group were perfused with the same volume of distilled water. Rats in each group were administrated at the wakeful time after reperfusion immediately. ③ Preparation of brain tissue: Rats were anesthetized at 3, 5, 7, 14, 21 and 30 days after perfusion to obtain their brains, separate brain tissue on ischemic site, extract total RNA, perform RT-PCR and semi-quantitative analysis and detect expression of bFGF mRNA at ischemic brain tissue. ④ Statistical analysis: Intensity at each time point was measured with analysis of variance and F test. MAIN OUTCOME MEASURES: Changes of bFGF mRNA during proliferation and differentiation of NSCs in ischemic brain tissue at each time point after cerebral ischemia/reperfusion injury. RESULTS: All 192 rats were involved in the final analysis. Expression of bFGF mRNA was hardly measured at focal side of rats in sham operation group. Otherwise, expression of bFGF mRNA was measured at various time points at ischemic side of rats in model group; moreover, the expression was the strongest on the 7th day, decreased on the 14th day and fallen down to the basic value on the 30th day. At 5, 7, 14, 21 and 30 days after modeling, expressions of bFGF mRNA at focal side were 0.86±0.04, 0.87±0.04; 0.88±0.02, 0.87±0.02; 0.79±0.02, 0.81±0.03; 0.52±0.04, 0.54±0.04; 0.46±0.03, 0.45±0.03 in high-dosage Tongxinluo group and low-dosage Tongxinluo group, respectively, which were stronger than those in model group (0.62±0.06, 0.63±0.05, 0.52±0.06, 0.43±0.06, 0.19±0.04, P < 0.05). Expression of bFGF mRNA at each time point was similar in high-dosage Tongxinluo group to that in low-dosage Tongxinluo group. In addition, expression of bFGF mRNA was the strongest at focal side in high-dosage Tongxinluo group and low-dosage Tongxinluo group on the 7th day after modeling; meanwhile, the expression was still stronger within 30 days after ischemia. CONCLUSION: ① Tongxinluo can strengthen the expression of bFGF mRNA at ischemic side; meanwhile, the expression may last for 30 days. ② This effect does not show as dosage-dependence. | Ruixue Yin Bingxun Lu Lixin Wang Jianzhong Fan Changjun Lu Hongzhen Zhou | 2006 | Neural Regeneration Research2006，1，6： | 0 |
| 17 | Algorithms for the Prize-Collecting k-Steiner Tree Problem显示文摘In this paper,we study the prize-collecting k-Steiner tree(PCkST) problem.We are given a graph G=(V,E) and an integer k.The graph is connected and undirected.A vertex r ∈ V called root and a subset R?V called terminals are also given.A feasible solution for the PCkST is a tree F rooted at r and connecting at least k vertices in R.Excluding a vertex from the tree incurs a penalty cost,and including an edge in the tree incurs an edge cost.We wish to find a feasible solution with minimum total cost.The total cost of a tree F is the sum of the edge costs of the edges in F and the penalty costs of the vertices not in F.We present a simple approximation algorithm with the ratio of 5.9672 for the PCkST.This algorithm uses the approximation algorithms for the prize-collecting Steiner tree(PCST) problem and the k-Steiner tree(kST) problem as subroutines.Then we propose a primal-dual based approximation algorithm and improve the approximation ratio to 5. | Lu Han Changjun Wang Dachuan Xu Dongmei Zhang | 2022 | Tsinghua Science and Technology2022，27，5： | 0 |

| 19 | Large-Scale Vehicle Platooning:Advances and Challenges in Scheduling and Planning Techniques显示文摘Through vehicle-to-vehicle(V2V)communication,autonomizing a vehicle platoon can significantly reduce the distance between vehicles,thereby reducing air resistance and improving road traffic efficiency.The gradual maturation of platoon control technology is enabling vehicle platoons to achieve basic driving functions,thereby permitting large-scale vehicle platoon scheduling and planning,which is essential for industrialized platoon applications and generates significant economic benefits.Scheduling and planning are required in many aspects of vehicle platoon operation;here,we outline the advantages and challenges of a number of the most important applications,including platoon formation scheduling,lane-change planning,passing traffic light scheduling,and vehicle resource allocation.This paper’s primary objective is to integrate current independent platoon scheduling and planning techniques into an integrated architecture to meet the demands of large-scale platoon applications.To this end,we first summarize the general techniques of vehicle platoon scheduling and planning,then list the primary scenarios for scheduling and planning technique application,and finally discuss current challenges and future development trends in platoon scheduling and planning.We hope that this paper can encourage related platoon researchers to conduct more systematic research and integrate multiple platoon scheduling and planning technologies and applications. | Jing Hou Guang Chen Jin Huang Yingjun Qiao Lu Xiong Fuxi Wen Alois Knoll Changjun Jiang | 2023 | Engineering2023，，9： | 0 |
| 20 | Relations between soil heterogeneity and common reed(Phragmites australis Trin.ex Steud.) colonization in the Keriya River Basin,Xinjiang of China显示文摘How common reed(Phragmites australis Trin. ex Steud.) colonization correlates to soil heterogeneity and environmental determinants remains unclear in arid areas. We conducted a field investigation and soil sampling in 100 plots along Keriya River Basin to uncover the relationship between common reed and heterogeneous soils. Reed colonization variables and its soil properties were measured and recorded for the analysis of their relationship using Pearson correlation and redundancy analysis methods. The comparison results of common reed characteristics among 100 plots showed that common reeds performed strong tolerance and ecophysiological plasticity to edaphic stresses. Common reed colonization was tightly connected to soil heterogeneity according to the correlation analysis between its colonization characteristics and soil properties. Common reed colonization got feedbacks on soil properties as well, including the increase of soil organic matter and the alleviation of salt uplifting. The main limiting environmental determinant of common reed colonization was soil salt, followed by pH and soil water content. | Lu GONG ChangJun LI Tashpolat TIYIP | 2014 | Journal of Arid Land2014，6，6： | 0 |
