| 1 | Nondestructive 3D Image Analysis Pipeline to Extract Rice Grain Traits Using X-Ray Computed Tomography显示文摘The traits of rice panicles play important roles in yield assessment,variety classification,rice breeding,and cultivation management.Most traditional grain phenotyping methods require threshing and thus are time-consuming and labor-intensive;moreover,these methods cannot obtain 3D grain traits.In this work,based on X-ray computed tomography,we proposed an image analysis method to extract twenty-two 3D grain traits.After 104 samples were tested,the R^(2) values between the extracted and manual measurements of the grain number and grain length were 0.980 and 0.960,respectively.We also found a high correlation between the total grain volume and weight.In addition,the extracted 3D grain traits were used to classify the rice varieties,and the support vector machine classifier had a higher recognition accuracy than the stepwise discriminant analysis and random forest classifiers.In conclusion,we developed a 3D image analysis pipeline to extract rice grain traits using X-ray computed tomography that can provide more 3D grain information and could benefit future research on rice functional genomics and rice breeding. | Weijuan Hu Can Zhang Yuqiang Jiang Chenglong Huang Qian Liu Lizhong Xiong Wanneng Yang Fan Chen | 2020 | Plant Phenomics2020，2，1： | 6 |

| 5 | Study on Wall Temperature Distribution of Oscillating Tube显示文摘The wall temperature distribution and heat transfer process of the oscillating tube have been investigated in thispaper using both numerical simulation and experimental method. The wall temperature of oscillating tube increasesrapidly in the inlet and then decreases slowly, moreover, the rally phenomenon of wall temperature nearthe closed end is observed. With the increase of jet flow frequency, the highest wall temperature increases and thelocation of that moves towards the inlet. The velocity of pressure wave in the oscillating tube almost remainsconstant even its intensity changes. The quantity of heat transfer between the gas and inner wall of the oscillatingtube determines the wall temperature of every location, and the pressure wave disturbance can cause the heattransfer quantity change. Each pressure wave has its own disturbance range. The wall temperature distribution canbe explained by the change of pressure wave intensity and its disturbance time. Besides, the step and rally of walltemperature are discussed, which shows that the conditions of heat transfer can be improved due to intersection orreflection of pressure waves. | Dapeng HU Peiqi LIU Wenjing ZHAO Che ZHU Yudong WANG Yuqiang DAI Jiupeng ZOU | 2009 | Journal of Thermal Science2009，18，3： | 2 |

The new IFV project combines the advantage of running the shell and tube heat exchangers at high pressure with the advantage of compact space of heat exchangers. Thermal analysis on the two processes of forced convection and vaporization type heat transfer in the spiral wound tubes and vapor condensation /re-boiling type of heat transfer via intermediate fluid in shell side shows the feasibility of this promising technology. | Liu Fengxia Dai Yuqiang Wei Wei Zou Jiupeng Zhu Che Dong Chao Hu Dapeng | 2013 | China Petroleum Processing & Petrochemical Technology2013，15，1： | 2 |
| 7 | A Study on the Biocompatibility of MgO Coating Prepared by Anodic Oxidation Method on Magnesium Metal显示文摘Magnesium(Mg),is widely used for the bone repair in oral and orthopedic application due to excellent bioactivity,degradation and biocompatibility.However,the range of application is greatly limited because of the rapid degradation of Mg metal in the body.Surface modification is an effective method to enhance the corrosion resistance and reduce the degradation rate of Mg metal.In the present study,pure Mg metal(P-Mg)was subjected to alkali-heat treatment(AT-Mg)or anodic oxidation-heat treatment(AO-HT-Mg).Both AT-Mg and AO-HT-Mg had a layer of MgO on their surfaces after treatment.Then the effects of MgO coating on corrosion resistance,bioactivity,Mesenchymal Stem Cells’(MSCs)proliferation,adhesion and osteogenic differentiation,and the bone repair capability of Mg metal were investigated.We found both AT-Mg and AO-HT-Mg had stronger corrosion resistance than P-Mg.MSCs on both AT-Mg and AO-HT-Mg had higher expression of proteins and genes of ALP,OCN,Col-I and Runx2 than those on P-Mg.They also showed better bone repair property than P-Mg in vivo.In general,MgO layer formed by anodic oxidation-heat treatment had better resistance and biocompatibility than that produced by alkali-heat treatment.This study indicated the MgO coating not only improved the corrosion resistance of Mg metal,but also promoted the osteogenic differentiation of MSCs and bone regeneration. | Yangmei Chen Xugang Lu Fenghua Zhao Yi Hu Shibing Xiong Yuqiang Guo Ping Huang Bangcheng Yang | 2020 | Journal of Bionic Engineering2020，17，1： | 2 |
| 8 | Seasonal patterns of root and shoot interactions in an alpine meadow on the Tibetan Plateau显示文摘Aims Numerous studies have showed that the balance between negative and positive plant–plant interactions shifted along environmental gradients.But little is known how the positive or negative plant–plant interactions varied with temporal fluctuating habitat conditions and plant ontogenetic phases.Methods In a 2-year experiment,the four perennial grasses(Kobresia humilis,Stipa aliena,Elymus nutans and Saussurea superba)were grown under four interaction treatments(no root or shoot interaction,only shoot interaction,only root interaction,root and shoot interaction).Intensity of above-and belowground interactions is proposed to vary with the fluctuation of seasonal climatic conditions and soil available nutrients.Here we report measurements of above-and belowground interactions during entire growing season.Correlation between plant interaction intensity and seasonal soil available N as well as habitat climate conditions was also performed.Important findings Our experiment found that root interactions had negative effect on plant growth for the four species during growing season.However,both negative and positive shoot interactions occurred among the four species.Despite there being shoot facilitative effect for E.nutans and S.superba,the full interaction was negative,suggested that root interaction take more important role on plant growth than that of shoot interaction.The interaction between root and shoot effect varied as a function of species identity and growth phases.The weak correlation of plant interaction intensity to habitat environmental factors suggested that plant ontogenetic characteristics may be primary factors causing temporal variation in plant interaction. | Minghua Song Qiwu Hu Yuqiang Tian Hua Ouyang | 2012 | Journal of Plant Ecology2012，5，2： | 2 |

| 10 | Comparison of survival prediction values of different scoring models for patients undergoing transjugular intrahepatic portal shunt:A multicenter retrospective study显示文摘Aim:The aim of this study is to compare the prognostic values of the Child–Pugh,integrated model for end‐stage liver disease(iMELD),albumin–bilirubin(ALBI),and Freiburg index of postsurvival(FIPS)scores in patients undergoing transjugular intrahepatic portosystemic shunt(TIPS).Methods:We conducted a multicenter retrospective study including patients who underwent TIPS by collecting data from several hospitals in southwest China between January 2014 and February 2021.We compared the performance of different scoring models for survival prediction in these patients.The performance of each scoring model was assessed via area under the receiver‐operating characteristic(AUROC)curve analysis.Results:The study included 378 TIPS patients(268 men,110 women;median age 52[interquartile range,45–60]years).Age;cirrhosis etiology;ascites severity;albumin levels;international normalized ratio;total bilirubin levels;sodium levels;and Child–Pugh,iMELD,ALBI,and FIPS scores were significant prognostic factors in cirrhotic patients who underwent TIPS.The Child–Pugh,iMELD,ALBI,and FIPS scores were all independent predictors of survival in TIPS patients.Survival analysis showed that all scoring models effectively stratified the prognostic risk of these patients.The Child–Pugh score was the best predictor of postoperative survival,followed by the ALBI and FIPS scores.The iMELD score was the worst predictor.The Child–Pugh,iMELD,ALBI,and FIPS scores predicted the 1‐year postoperative survival,with AUROC values of 0.832,0.677,0.761,and 0.745,respectively,and the 3‐year postoperative survival,with AUROC values of 0.710,0.668,0.721,and 0.658,respectively.The calibration curve showed that the Child–Pugh,ALBI,and FIPS models performed well in predicting 1‐and 3‐year survival,whereas the iMELD model was a poor predictor.Conclusions:The four scoring models can predict survival in cirrhotic patients after TIPS and can effectively stratify prognostic risk.The Child–Pugh score may be more suitable for predicting survival after TIPS in patients with liver cirrhosis. | Yuyi Liu Zhiyong Mu Wei Xiong Hong Hu Aimin Liu Xuan An Yuqiang Xu Haohong Yu Jinneng Wang Jun Wang Xiao Xiao Dongfeng Chen Liangzhi Wen | 2022 | Portal Hypertension & Cirrhosis2022，1，2： | 1 |

| 14 | Study on wave rotor refrigerators显示文摘As a novel generation of a rotational gas wave machine,the wave rotor refrigerator(WRR)is an unsteadyflow device used for refrigeration,in whose passages pressured streams directly contact and exchange energy due to the movement of pressure waves.In this paper,the working mechanism and refrigeration principle are inves-tigated based on the one-dimensional unsteadyflow theory.A basic limitation on main structural parameters and operating parameters is deduced and the wave diagram of WRR to guide designing is sketched.The main influential factors are studied through an experiment.In the DUT Gas Wave Refrigeration Studying and Development Center(GWRSDC)lab,the isentropic efficiency can now reach about 65%.The results show that the WRR is a feasible and promising technology in pressured gas refrigeration cases. | Yuqiang DAI Dapeng HU Meixia DING | 2009 | Frontiers of Chemical Science and Engineering2009，3，1： | 0 |
| 15 | Expert Consensus on Diagnosis and Treatment of End-Stage Liver Disease Complicated with Infections显示文摘End-stage liver disease(ESLD)is a life-threatening clinical syndrome that markedly increases mortality in patients with infections.In patients with ESLD,infections can induce or aggravate the occurrence of liver decompensation.Consequently,infections are among the most common complications of disease progression.There is a lack of working procedure for early diagnosis and appropriate management for patients with ESLD complicated by infections as well as local and international guidelines or consensus.This consensus assembled up-to-date knowledge and experience across Chinese colleagues,providing data on principles as well as working procedures for the diagnosis and treatment of patients with ESLD complicated by infections. | Qin Ning Tao Chen Guiqiang Wang Dong Xu Yanyan Yu Qing Mao Taisheng Li Lanjuan Li Jun Li Xiaoju Lu Jiabin Li Zhiwei Li Wenhong Zhang Yonghong Xiao Qinghua Meng Yuqiang Mi Jia Shang Yunsong Yu Yingren Zhao Caiyan Zhao Hong Zhao Jianrong Huang Jie Peng Hong Tang Xiaoping Tang Jinhua Hu Bijie Hu Wei Guo Bo Zheng Baiyi Chen Yuexin Zhang Jia Wei Jifang Sheng Zhi Chen Minggui Wang Qing Xie Yuming Wang Fu-Sheng Wang Jinlin Hou Zhongping Duan Lai Wei Jidong Jia Chinese Society of Infectious Disease of Chinese Medical Association | 2022 | Infectious Diseases & Immunity2022，2，3： | 0 |
| 16 | Sensitive DNA Mutation Detection at Physiological Temperature with Endonuclease IV by Inhibiting Its Side Activity显示文摘Endonuclease IV(Endo IV)has the side activity to cleave the apurinic/apyrimidinic site in the single-stranded DNA probe(AP-ssDNA),which adversely affects its performance in single-nucleotide variation(SNV)detection.In this work,we developed a simple strategy to inhibit Endo IV's side activity by introducing an assistant strand into the detection system.The assistant strand effectively inhibited the side-activity of Endo IV by conf ini ng the freedom of AP-ssDNA through rigid double-stranded DNA formati on,and the inhibition efficiency could reach 98%.About 20 times enhancement of the discrimination factor(DF)was obtained compared to the detection system without the assistant strand.After optimization,a mean DF value was calculated to be 738 for different mutation types,and the sample with 0.005%allele frequency was discriminated from the wild-type target.Another advantage of using an assists nt stra nd was that the SNV detection could be executed at physiological temperature without precise temperature optimization as in other Endo IV-based SNV detection system.Besides,EGFR T790M mutant in the synthesized and clinical samples was detected by our strategy.The results showed satisfactory sensitivity and accuracy by comparison with Sanger sequencing.Thus,this strategy has the potential to be applied in the field of precision medicine. | Zhen Zhang Longjie Li Qingxu Liu Yuqiang Hu Wenqian Yuan Xianjin Xiao Tongbo Wu | 2021 | Chinese Journal of Chemistry2021，39，9： | 0 |
| 17 | Numerical Simulations on Geometrical Properties of Wall-attaching Transonic Jet显示文摘Effects of operating conditions and device's geometrical sizes on geometrical properties of wall-attaching transonic jet between two parallel plat plates are numerically simulated. Conclusions are as follows: 1) Upriver part of the wall-attaching jet's center streamline is in good accordance with parabola; 2) When both gas inlet pressure and outlet pressure as well as their ratio are not too high ( the outlet pressure is less than 10 MPa and the pressure ratio is less than 3), the center streamlines of the wall-attaching jet with the same pressure ratio coincide with each other very well, and the deflection degree of the center streamline decreases with rise of the pressure ratio; 3) The deflection degree of the jet's center streamline decreases with either broadening of nozzle's throat or rise of wall offset; 4) With rise of the pressure ratio, attachment distance of the jet increases, but the increase rate descends; 5) The attachment distance ascends with rise of either the nozzle's throat or the wall offset. | Hu Dapeng Chen Zuzhi Dai Yuqiang Chen Shengtao | 2008 | Engineering Sciences2008，6，1： | 0 |
| 18 | Microscopic pore-fracture configuration and gas-filled mechanism of shale reservoirs in the western Chongqing area,Sichuan Basin,China显示文摘Taking the Upper Ordovician Wufeng Formation to Lower Silurian Longmaxi Formation shale reservoirs in western Chongqing area as the study target,the argon ion polishing scanning electron microscope and nuclear magnetic resonance(NMR)experiments of different saturated wetting media were carried out.Based on the image processing technology and the results of gas desorption,the pore-fracture configuration of the shale reservoirs and its influence on gas-filled mechanism were analyzed.(1)The reservoir space includes organic pores,inorganic pores and micro-fractures and there are obvious differences between wells in the development characteristics of micro-fractures;the organic pores adjacent to the micro-fractures are poorly developed,while the inorganic pores are well preserved.(2)According to the type,development degree and contact relationship of organic pore and micro-fracture,the pore-fracture configuration of the shale reservoir is divided into four types.(3)Based on the differences in NMR T_(2) spectra of shale samples saturated with oil and water,an evaluation parameter of pore-fracture configuration was constructed and calculated.The smaller the parameter,the better the pore-fracture configuration is.(4)The shale reservoir with good pore-fracture configuration has well-developed organic pores,high porosity,high permeability and high gas content,while the shale reservoir with poor pore-fracture configuration has micro-fractures developed,which improves the natural gas conductivity and leads to low porosity and gas content of the reservoir.(5)Based on pore-fracture configuration,from the perspective of organic matter generating hydrocarbon,micro-fracture providing migration channel,three types of micro gas-filled models of shale gas were established. | FU Yonghong JIANG Yuqiang DONG Dazhong HU Qinhong LEI Zhi'an PENG Hao GU Yifan MA Shaoguang WANG Zimeng YIN Xingping WANG Zhanlei | 2021 | Petroleum Exploration and Development2021，48，5： | 0 |
| 19 | Probing and modulating the interactions of the DNAzyme with DNA-functionalized nanoparticles显示文摘DNA-functionalized gold nanoparticles are one of the most versatile bionanomaterials for biomedical and clinical diagnosis. Herein, we discovered that the performance of DNAzyme cleaving the substrate is highly related to its length. This intriguing phenomenon only appears at the interfaces of DNAfunctionalized gold nanoparticles. We systematically investigated the causes of this phenomenon. We conjectured that the DNAzyme with extended nucleotides that do not match its substrate strand is vulnerable to non-specific adsorption, electrostatic repulsion, and steric hindrance. Based on our improved understanding of this phenomenon, we have successfully developed a highly sensitive and specific amplifiable biosensor to detect human apurinic/apyrimidinic endonuclease 1. | Yuqiang Hu Zhen Zhang Wei Zhang Minghao Hu Xianjin Xiao Tongbo Wu | 2022 | Chinese Chemical Letters2022，33，6： | 0 |
