| 1 | Determining "abnormal" levator hiatus distensibility using three-dimensional transperineal ultrasound in Chinese women显示文摘The dimension of the levator hiatus is a possible predictor of pelvic organ prolapse (POP). Thisretrospective study investigated 360 women who went to urogynecological clinic for pelvic floor discomfort.Levator hiatus dimensions were obtained by three-dimensional transperineal ultrasound and results werecompared between women with and without significantly objective prolapse (International Continence SocietyPOP quantification, grade 2 or higher). Receiver operating characteristic (ROC) curve analyses were performed todetermine valid screening index for detecting abnormal levator hiatus distensibility. Women with significantlyobjective prolapse had significantly higher levator hiatus dimensions than those without (all P 〈 0.001). ROCcurve analyses confirmed that hiatal area (HA) of 19.5 cm2 during Valsalva maneuver can be used as single-screening index for abnormal levator hiatus distensibility with sensitivity of 0.80 and specificity of 0.70. In thisstudy, we used a two-step method and achieved higher sensibility (0.80 vs. 0.87) without reducing specificity (0.70vs. 0.71) compared with a single-screening index method. As a result, we suggest that HA ≥ 19.5 cm2 duringValsalva maneuver is an indicator of abnormal levator hiatus distensibility in Chinese women and that the two-step method has higher sensitivity in detecting abnormal distensibility. | Chaoran Dou Qin Li Tao Ying Yulin Yan Xia Wang Bing Hu | 2018 | Frontiers of Medicine2018，12，5： | 21 |
| 2 | Effect of wheat bran insoluble dietary fiber with different particle size on the texture properties, protein secondary structure, and microstructure of noodles显示文摘This study was conducted to explore how the insoluble dietary fiber(IDF)of wheat bran with different particle size affects the texture properties,water distribution,protein secondary structure and microstructure of noodles.The results suggested that IDF addition increased the cooking loss and decreased the sensory evaluation because of the damage on dough structure,while as the IDF particle size decreased,the sensory score increased from 78.8 to 82.3 and cooking loss decreased from 8.65%to 7.65%,which could be attributed to that small particle-sized IDF limited the damage on protein network structure,decreased the T22 and t-structure,and increased the β1-structure.Moreover,IDF particle size had a significant correlation with protein secondary structures,texture properties and evaluation score of noodles.In conclusion,adding appropriate particle sizewould be an effectiveway of enhancing the nutritional and textural properties of noodles. | Jian Zhang Mengqin Li Chaoran Li Yanqi Liu | 2019 | Grain & Oil Science and Technology2019，2，4： | 20 |
| 3 | Degradation of Nitrobenzene-Containing Wastewater with O_3 and H_2O_2 by High Gravity Technology显示文摘Nitrobenzene-containing industrial wastewater was degraded in the presence of ozonecoupled with H2O2 by high gravity technology. The effect of high gravity factor, H2O2 concentration, pH value, liquid flow-rate, and reaction time on the efficiency for removal of nitrobenzene was investigated. The experimental results show that the high gravity technology enhances the ozone utilization efficiency with O3 /H2O2 showing synergistic effect. The degradation efficiency in terms of the COD removal rate and nitrobenzene removal rate reached 45.8% and 50.4%, respectively, under the following reaction conditions, viz.: a high gravity factor of 66.54, a pH value of 9, a H2O2 /O3 molar ratio of 1:1, a liquid flow rate of 140L/h, an ozone concentration of 40mg/L, a H2O2 multiple dosing mode of 6mL/h, and a reaction time of 4h. Compared with the performance of conventional stirred aeration mixers, the high gravity technology could increase the COD and nitrobenzene removal rate related with the nitrobenzene-containing wastewater by 22.9% and 23.3%, respectively. | Jiao Weizhou Liu Youzhi Liu Wenli Li Jing Shao Fan Wang Chaoran | 2013 | China Petroleum Processing & Petrochemical Technology2013，15，1： | 16 |
| 4 | A Flexible Multi-Layer Map Model Designed for Lane-Level Route Planning in Autonomous Vehicles显示文摘An increasing number of drivers are relying on digital map navigation systems in vehicles or mobile phones to select optimal driving routes in order to save time and improve safety. In the near future, digital map navigation systems are expected to play more important roles in transportation systems. In order to extend current navigation systems to more applications, two fundamental problems must be resolved: the lane-level map model and lane-level route planning. This study proposes solutions to both problems. The current limitation of the lane-level map model is not its accuracy but its flexibility;this study proposes a novel seven-layer map structure, called as Tsinghua map model, which is able to support autonomous driving in a flexible and efficient way. For lane-level route planning, we propose a hierarchical route-searching algorithm to accelerate the planning process, even in the presence of complicated lane networks. In addition, we model the travel costs allocated for lane-level road networks by analyzing vehicle maneuvers in traversing lanes, changing lanes, and turning at intersections. Tests were performed on both a grid network and a real lane-level road network to demonstrate the validity and efficiency of the proposed algorithm. | Kun Jiang Diange Yang Chaoran Liu Tao Zhang Zhongyang Xiao | 2019 | Engineering2019，5，2： | 14 |
| 5 | Degradation of Wastewater Containing Nitrobenzene by High Gravity-Ultrasonic/Ozonation/Electrolysis Technology显示文摘The integrated high gravity-ultrasonic/ozonation/electrolysis technology was applied in the pretreatment of wastewater containing nitrobenzene.The effect of pH value,high gravity factor,liquid flow-rate and electric current density on removal of COD and nitrobenzene compounds was investigated.Experimental results have determined the optimal process regime involving a high gravity factor of 100,an electric current density of 20mA/cm2,a liquid flow-rate of 100L/h,and an initial liquid pH value of 11.After the wastewater had been treated for 180 min,the degradation of nitrobenzene and COD reached 99% and 80%,respectively,with the biochemical coefficient(BOD/COD) equating to 0.64,and the subsequent treatment of wastewater could be carried out by conventional biochemical means.Compared with traditional aerationozone contactors,a rotating packed bed with high mass transfer characteristics could be used to increase the ozonation treatment efficiency. | Jiao Weizhou Liu Youzhi Shao Fan Liu Wenli Li Jing Wang Chaoran | 2012 | China Petroleum Processing & Petrochemical Technology2012，14，3： | 11 |

| 8 | Additivity of pore structural parameters of granular activated carbons derived from different coals and their blends显示文摘A series of granular activated carbons(GACs) were prepared by briquetting method from Chinese coals of different ranks and their blends,with coal pitch as the binder.Pore structural parameters including BET specific surface area(SBET),total pore volume(VT) and average pore diameter(da) were measured and calculated as well as process parameters such as yield of char(CY) and burn-off(B).The relationship between the pore structural parameters of the GAC from coal blend(BC-GAC) and the ones of the GACs from corresponding single coals(SC-GACs) was analyzed,in which an index,the relative error(d),was presented to define the bias between fitted values and experimental values of these parameters of the BC-GACs.The results show that the BC-GAC keeps qualitatively the pore structural features of the SC-GACs;as concerned as the quantitative relationship,the pore structural parameters of the BC-GAC from coal blend consisting of non-caking coals can be obtained by adding proportionally the pore structural parameters of the SC-GACs with d less than 10%.Meanwhile,for the BC-GAC from coal blend containing weak caking bituminous coal,the d increases up to 25% and the experimental pore size distribution differs greatly from the fitted one. | Yao Xin Xie Qiang Yang Chuan Zhang Bo Wan Chaoran Cui Shanshan | 2016 | International Journal of Mining Science and Technology2016，26，4： | 6 |
| 9 | Pre-course student performance prediction with multi-instance multi-label learning显示文摘Dear editor,Studying courses is one of the most basic and important tasks for college students.For each new course,the initial period of learning is crucial for students,and seriously influences subsequent learning activities.However,given a large number of classes in universities,it has become impossible for teachers to keep track of the individual performance of each student.In these circumstances,it is desirable to predict each student’s performance on a certain course prior to its commencement. | Yuling MA Chaoran CUI Xiushan NIE Gongping YANG Kashif SHAHEED Yilong YIN | 2019 | Science China(Information Sciences)2019，62，2： | 5 |
| 10 | Pharmacological Activation of RXR-a Promotes Hematoma Absorption via a PPAR-y-dependent Pathway After Intracerebral Hemorrhage显示文摘Endogenously eliminating the hematoma is a favorable strategy in addressing intracerebral hemorrhage(ICH).This study sought to determine the role of retinoid X receptor-ot(RXR-a)in the context of hematoma absorption after ICH.Our results showed that pharmacologically activating RXR-a with bexarotene significantly accelerated hematoma clearance and alleviated neurological dysfunction after ICH.RXR-ot was expressed in microglia/macro-phages,neurons,and astrocytes.Mechanistically,bexarotene promoted the nuclear translocation of RXR-a and PPAR-y,as well as reducing neuroinflammation by modulating microglia/macrophage reprograming from the Ml into the M2 phenotype.Furthermore,all the beneficial effects of RXR-a in ICH were reversed by the PPAR-y inhibitor GW9662.In conclusion,the pharmacological activation of RXR-a confers robust neuroprotection against ICH by accelerating hematoma clearance and repolarizing microglia/macrophages towards the M2 phenotype through PPAR-y-related mechanisms.Our data support the notion that RXR-ot might be a promising therapeutic target for ICH. | Chaoran Xu Huaijun Chen Shengjun Zhou Chenjun Sun Xiaolong Xia Yucong Peng Jianfeng Zhuang Xiongjie Fu Hanhai Zeng Hang Zhou Yang Cao Qian Yu Yin Li Libin Hu Guoyang Zhou Feng Yan Gao Chen Jianru Li | 2021 | Neuroscience Bulletin2021，37，10： | 4 |
| 11 | Photonic matrix multiplication lights up photonicaccelerator and beyond显示文摘Matrix computation,as a fundamental building block of information processing in science and technology,contributes most of the computational overheads in modern signal processing and artificial intelligence algorithms.Photonic accelerators are designed to accelerate specific categories of computing in the optical domain,especially matrix multiplication,to address the growing demand for computing resources and capacity.Photonic matrix multiplication has much potential to expand the domain of telecommunication,and artificial intelligence benefiting from its superior performance.Recent research in photonic matrix multiplication has flourished and may provide opportunities to develop applications that are unachievable at present by conventional electronic processors.In this review,we first introduce the methods of photonic matrix multiplication,mainly including the plane light conversion method,Mach–Zehnder interferometer method and wavelength division multiplexing method.We also summarize the developmental milestones of photonic matrix multiplication and the related applications.Then,we review their detailed advances in applications to optical signal processing and artificial neural networks in recent years.Finally,we comment on the challenges and perspectives of photonic matrix multiplication and photonic acceleration. | Hailong Zhou Jianji Dong Junwei Cheng Wenchan Dong Chaoran Huang Yichen Shen Qiming Zhang Min Gu Chao Qian Hongsheng Chen Zhichao Ruan Xinliang Zhang | 2022 | Light(Science & Applications)2022，11，2： | 4 |
| 12 | A novel miRNA negatively regulates resistance to Glomerella leaf spot by suppressing expression of an NBS gene in apple显示文摘Glomerella leaf spot(GLS)of apple(Malus×domestica Borkh.),caused by Glomerella cingulata,is an emerging fungal epidemic threatening the apple industry.Little is known about the molecular mechanism underlying resistance to this devastating fungus.In this study,high-throughput sequencing technology was used to identify microRNAs(miRNAs)involved in GLS resistance in apple.We focused on miRNAs that target genes related to disease and found that expression of a novel miRNA,Md-miRln20,was higher in susceptible apple varieties than in resistant ones.Furthermore,its target gene Md-TN1-GLS exhibited the opposite expression pattern,which suggested that the expression levels of Md-miRln20 and its target gene are closely related to apple resistance to GLS.Furthermore,downregulation of MdmiRln20 in susceptible apple leaves resulted in upregulation of Md-TN1-GLS and reduced the disease incidence.Conversely,overexpression of Md-miRln20 in resistant apple leaves suppressed Md-TN1-GLS expression,with increased disease incidence.We demonstrated that Md-miRln20 negatively regulates resistance to GLS by suppressing Md-TN1-GLS expression and showed,for the first time,a crucial role for miRNA in response to GLS in apple. | Yi Zhang Qiulei Zhang Li Hao Shengnan Wang Shengyuan Wang Wenna Zhang Chaoran Xu Yunfei Yu Tianzhong Li | 2019 | Horticulture Research2019，6，1： | 4 |
| 13 | Nicotine from cigarette smoking and diet and Parkinson disease:a review显示文摘Evidence from epidemiological studies suggest a relationship between cigarette smoking and low risk of Parkinson disease(PD).As a major component of tobacco smoke,nicotine has been proposed to be a substance for preventing against PD risk,with a key role in regulating striatal activity and behaviors mediated through the dopaminergic system.Animal studies also showed that nicotine could modulate dopamine transmission and reduce levodopa-induced dyskinesias.However,previous clinical trials yield controversial results regarding nicotine treatment.In this review,we updated epidemiological,preclinical and clinical data,and studies on nicotine from diet.We also reviewed interactions between genetic factors and cigarette smoking.As a small amount of nicotine can saturate a substantial portion of nicotine receptors in the brain,nicotine from other sources,such as diet,could be a promising therapeutic substance for protection against PD. | Chaoran Ma Yesong Liu Samantha Neumann Xiang Gao | 2017 | Translational Neurodegeneration2017，6，1： | 4 |
| 14 | Low soil temperature reducing the yield of drip irrigated rice in arid area by influencing anther development and pollination显示文摘Drip irrigation can produce high rice yields with significant water savings;therefore,it is widely used in arid area water-scarce northern China.However,high-frequency irrigation of drip irrigation with low temperature well water leads to low root zone temperature and significantly reduce the rice yield compared to normal temperature water irrigated rice,for example,reservoir water.The main purpose of this paper is to investigate the effects of low soil temperature on the yield reduction of drip irrigated rice in the spike differentiation stage.The experiment set the soil temperatures at 18℃,24℃and 30℃under two irrigation methods(flood and drip irrigation),respectively.The results showed that,at the 30℃soil temperature,drip irrigation increased total root length by 53%but reduced root water conductivity by 9%compared with flood irrigation.Drip irrigation also increased leaf abscisic acid and proline concentrations by 13%and 5%,respectively.These results indicated that drip irrigated rice was under mild water stress.In the 18℃soil temperature,drip irrigation reduced hydraulic conductivity by 58%,leaf water potential by 40%and leaf net photosynthesis by 25%compared with flood irrigation.The starch concentration in male gametes was also 30%less in the drip irrigation treatment than in the flood irrigation treatment at soil temperature 18℃.Therefore,the main reason for the yield reduction of drip irrigated rice was that the low temperature aggravates the physiological drought of rice and leads to the decrease of starch content in male gametes and low pollination fertilization rate.Low temperature aggravates physiological water deficit in drip irrigated rice and leads to lower starch content in male gametes and low pollination fertilization rate,which is the main reason for the reduced yield of drip irrigated rice.Overall,the results indicated that the low soil temperatures aggravated the water stress that rice was under in the drip irrigated environment,causing declines both in the starch content of male gametes and in pollination rate.Low temperature will ultimately affect the rice yield under drip irrigation. | ZHANG Jun DONG Peng ZHANG Haoyu MENG Chaoran ZHANG Xinjiang HOU Jianwei WEI Changzhou | 2019 | Journal of Arid Land2019，11，3： | 3 |

| 17 | Two pathogenesis-related proteins interact with leucine-rich repeat proteins to promote Alternaria leaf spot resistance in apple显示文摘Alternaria leaf spot in apple(Malus x domestica),caused by the fungal pathogen Alternaria alternata f.sp.mali(also called A.mali),is a devastating disease resulting in substantial economic losses.We previously established that the resistance(R)protein MdRNL2,containing a coiled-coil,nucleotide-binding,and leucine-rich repeat(CC R-NB-LRR)domain,interacts with another CC R-NB-LRR protein,MdRNL6,to form a MdRNL2–MdRNL6 complex that confers resistance to A.mali.Here,to investigate the function of the MdRNL2–MdRNL6 complex,we identified two novel pathogenesis-related(PR)proteins,MdPR10-1 and MdPR10-2,that interact with MdRNL2.Yeast two-hybrid(Y2H)assays and bimolecular fluorescence complementation(BiFC)assays confirmed that MdPR10-1 and MdPR10-2 interact with MdRNL2 and MdRNL6 at the leucine-rich repeat domain.Transient expression assays demonstrated that accumulation of MdPR10-1 and MdPR10-2 enhanced the resistance of apple to four strains of A.mali that we tested:ALT1,GBYB2,BXSB5,and BXSB7.In vitro antifungal activity assays demonstrated that both the proteins contribute to Alternaria leaf spot resistance by inhibiting fungal growth.Our data provide evidence for a novel regulatory mechanism in which MdRNL2 and MdRNL6 interact with MdPR10-1 and MdPR10-2 to inhibit fungal growth,thereby contributing to Alternaria leaf spot resistance in apple.The identification of these two novel PR proteins will facilitate breeding for fungal disease resistance in apple. | Qiulei Zhang Chaoran Xu Haiyang Wei Wenqi Fan Tianzhong Li | 2021 | Horticulture Research2021，8，1： | 2 |
| 18 | Representing surface wind stress response to mesoscale SST perturbations in western coast of South America using Tikhonov regularization method显示文摘Interaction between mesoscale perturbations of sea surface temperature(SSTmeso)and wind stress(WSmeso)has great influences on the ocean upwelling system and turbulent mixing in the atmospheric boundary layer.Using daily Quik-SCAT wind speed data and AMSR-E SST data,SSTmeso and WSmeso fields in the western coast of South America are extracted by using a locally weighted regression method(LOESS).The spatial patterns of SSTmeso and WSmeso indicate strong mesoscale SST-wind stress coupling in the region.The coupling coefficient between SSTmeso and WSmeso is about 0.0095 N/(m^2·℃)in winter and 0.0082 N/(m^2·℃)in summer.Based on mesoscale coupling relationships,the mesoscale perturbations of wind stress divergence(Div(WSmeso))and curl(Curl(WSmeso))can be obtained from the SST gradient perturbations,which can be further used to derive wind stress vector perturbations using the Tikhonov regularization method.The computational examples are presented in the western coast of South America and the patterns of the reconstructed WS meso are highly consistent with SSTmeso,but the amplitude can be underestimated significantly.By matching the spatially averaged maximum standard deviations of reconstructed WSmeso magnitude and observations,a reasonable magnitude of WSmeso can be obtained when a rescaling factor of 2.2 is used.As current ocean models forced by prescribed wind cannot adequately capture the mesoscale wind stress response,the empirical wind stress perturbation model developed in this study can be used to take into account the feedback effects of the mesoscale wind stress-SST coupling in ocean modeling.Further applications are discussed for taking into account the feedback effects of the mesoscale coupling in largescale climate models and the uncoupled ocean models. | CUI Chaoran ZHANG Rong-Hua WANG Hongna WEI Yanzhou | 2020 | Journal of Oceanology and Limnology2020，38，3： | 2 |
| 19 | An improved artificial bee colony-random forest(IABC-RF)model for predicting the tunnel deformation due to an adjacent foundation pit excavation显示文摘An improved artificial bee colony-random forest(IABC-RF)model is proposed for predicting the tunnel deformation due to the excavation of an adjacent foundation pit.A new search strategy of the artificial bee colony(ABC)algorithm is herein developed and incorporated,with the results showing that a much higher computational efficiency can be achieved with the new model,while high computational accuracy can also be maintained.The improved ABC algorithm is thereafter utilised and combined with the random forest(RF)model,where four important hyper-parameters are optimized,for a tunnel deformation prediction.Results are thoroughly compared with those of other prediction methods based on machine learning(ML),as well as the monitored data on the site.Via the comparisons,the validity and effectiveness of the proposed model are fully demonstrated,and a more promising perspective can be seen of the method for its potential wide applications in geotechnical engineering. | Tugen Feng Chaoran Wang Jian Zhang Bin Wang Yin-Fu Jin | 2022 | Underground Space2022，7，4： | 2 |
| 20 | The effects of straw‑returning and inorganic K fertilizer on the carbon–nitrogen balance and reproductive growth of cotton显示文摘Background:Many studies have indicated that straw-returning could meet part or even all of the potassium(K)demand for crop growth in the field,but few have compared the effects of crop straw as K source and inorganic K fertilizer on carbon–nitrogen(C–N)balance of cotton and the reproductive growth.To address this,field experiments were conducted using the cotton cultivar,Siza 3,under there treatments(CK as control group one,no crop straw and inorganic K fertilizer were applied;K150 as control group two,150 kg·ha^(-1) of K2O was applied;and W9000,9000 kg·ha^(-1) wheat straw,which could provide K2O about 150 kg·ha^(-1),was incorporated into soil).Results:Although the final reproductive organ biomass did not differ between W9000 and K150,W9000 had a higher ratio of reproductive organ biomass to total biomass(RRT),suggesting that straw-returning was more conducive to the allocation of biomass to reproductive organs.The theoretical maximum biomass of reproductive organ was higher,but the average and maximum accumulation rates of reproductive organ biomass were 2.8%∼8.3%and 2.5%∼8.2%lower under W9000 than K150.Also,the duration of rapid-accumulation period for reproductive organ biomass(T)was 2.0∼2.8 d longer under W9000 than K150,which was a reason for the higher RRT under W9000.Straw-returning altered the dynamics of leaf K with the growth period,so that W9000 had a more drastic effect on leaf C metabolism than K150.Consequently,lower soluble sugar/free amino acid and C/N ratios were measured under W9000 than K150 at boll-setting(BSS)and boll-opening(BOS)stages.Higher leaf net photosynthetic rate,sucrose phosphate synthase and sucrose synthase activities,and lower acid invertase activity were observed under W9000 than K150 at BSS and BOS and these were more conducive to sucrose accumulation.However,less sucrose was measured under W9000 than K150 at these stages.This should be because straw-returning promoted the assimilate transport capacity when compared with inorganic K fertilizer application,which also explained the higher RRT under W9000 than K150.The lower acid invertase activity under W9000 inhibited the conversion of sucrose to other sugars,hence lower contents of soluble sugar and starch were measured under W9000 than K150.Conclusion:Under low K condition,crop straw as K source can increase the assimilate transport from source to sink,leading to lower C/N ratio in leaf and higher allocation of biomass to reproductive organs than inorganic K fertilizer. | HU Wei YU Chaoran ZHAO Wenqing LIU Ruixian YANG Changqinand ZHOU Zhiguo | 2021 | Journal of Cotton Research2021，4，4： | 2 |
