1An overview of the use of plastic-film mulching in China to increase crop yield and water-use efficiency显示文摘Since 1990,crop yields have stagnated in many parts of the world,posing a significant challenge to global food security[1].As such;innovative solutions are needed to increase the resource-use efficiency of cropping systems to produce more grains per unit area.Dongbao Sun Haigang Li Enli Wang Wenqing He Weiping Hao Changrong Yan Yuzhong Li Xurong Mei Yanqing Zhang Zhanxiang Sun Zhikuan Jia Huaiping Zhou Tinglu Fan Xucheng Zhang Qin Liu Fengju Wang Chaochun Zhang Jianbo Shen Qingsuo Wang Fusuo Zhang 2020National Science Review2020,7,10:19
2Interpretation of breast cancer screening guideline for Chinese women显示文摘Breast cancer is the most common malignant tumor in Chinese women.Early screening is the best way to improve the rates of early diagnosis and survival of breast cancer patients.The peak onset age for breast cancer in Chinese women is considerably younger than those in European and American women.It is imperative to develop breast cancer screening guideline that is suitable for Chinese women.By summarizing the current evidence on breast cancer screening in Chinese women,and referring to the latest guidelines and consensus on breast cancer screening in Europe,the United States,and East Asia,the China Anti-Cancer Association and National Clinical Research Center for Cancer(Tianjin Medical University Cancer Institute and Hospital)have formulated population-based guideline for breast cancer screening in Chinese women.The guideline provides recommendations on breast cancer screening for Chinese women at average or high risk of breast cancer according to the following three aspects:age of screening,screening methods,and screening interval.This article provides more detailed information to support the recommendations in this guideline and to provide more direction for current breast cancer screening practices in China.Yubei Huang Zhongsheng Tong Kexin Chen Ying Wang Peifang Liu Lin Gu Juntian Liu Jinpu Yu Fengju Song Wenhua Zhao Yehui Shi Hui Li Huaiyuan Xiao Xishan Hao 2019Cancer Biology & Medicine2019,16,4:10
3Model for Paleoearthquake Recurrence Along Baying Segment of the North Margin Fault of Fanshan Basin in Hebei Province显示文摘Based on the measurement of faulted geomorphic surfaces,large trench logging and systematic chronostratigraphic sampling,we suggest that the total slip amount along the Baying segment of the north margin fault of Fanshan Basin since 90 ka B.P.is 34 m.Nine paleoseismic events occurred in the last 75 ka.Among them,the four events A,B,C,and D revealed by the large trench were dated at 28 ka,14 ka,7.5 ka,and 656 B.P.,respectiv eJy.The model for paleoearthquake recurrence along the segment may have two stages; in the stage from 90 ka to 14 ka B.P.,the 'time-predictable model' is suitable,while in the stage from 14 ka B.P.to now,the 'displacement-attenuation model' applies.Ran Yongkang,Fang Zhongjing,Duan Ruitao,Li Zhiyi,Wang Jingbo,Yang Zhe,Ji Fengju,and Li JianpingInsatute of Geology,State Seismologlcal Bureau,Beijing 100029,China 1996Earthquake Research in China1996,10,1:3
4Spatial Distribution and Environmental Determinants of Denitrification Enzyme Activity in Reed-Dominated Raised Fields显示文摘Denitrification is an important process of nitrogen removal in lake ecosystems.However,the importance of denitrification across the entire soil-depth gradients including subsurface layers remains poorly understood.This study aims to determine the spatial pattern of soil denitrification enzyme activity(DEA) and its environmental determinants across the entire soil depth gradients in the raised fields in Baiyang Lake,North China.In two different zones of the raised fields(i.e.,water boundary vs.main body of the raised fields),the soil samples from 1.0 m to 1.1 m depth were collected,and the DEA and following environmental determinants were quantified:soil moisture,p H,total nitrogen(TN),ammonia nitrogen(NH4+-N),nitrate nitrogen(NO3–-N),total organic carbon(TOC),and rhizome biomass of Phragmites australis.The results showed that the soil DEA and environmental factors had a striking zonal distribution across the entire soil depth gradients.The soil DEA reached two peak values in the upper and middle soil layers,indicating that denitrification are important in both topsoil and subsurface of the raised fields.The correlation analysis showed that the DEA is negatively correlated with the soil depth(p < 0.05).However,this phenomenon did not occur in the distance to the water edge,except in the upper layers(from 0.2 m to 0.7 m) of the boundary zone of the raised fields.In the main body of the raised fields,the DEA level remained high;however,it showed no significant relationship with the distance to the water edge.The linear regression analysis showed significant positive correlation of the DEA with the soil TN,NO3–-N,NH4+-N,and TOC;whereas it showed negative correlation with soil p H.No significant correlations with soil moisture and temperature were observed.A positive correlation was also found between the DEA and rhizome biomass of P.australis.LAN Yan CUI Baoshan HAN Zhen LI Xia LI Fengju ZHANG Yongtao 2015Chinese Geographical Science2015,25,4:2

6Resilience patterns of human mobility in response to extreme urban floods显示文摘Large-scale disasters can disproportionately impact different population groups,causing prominent disparity and inequality,especially for the vulnerable and marginalized.Here,we investigate the resilience of human mobility under the disturbance of the unprecedented‘720’Zhengzhou flood in China in 2021 using records of 1.32 billion mobile phone signaling generated by 4.35 million people.We find that although pluvial floods can trigger mobility reductions,the overall structural dynamics of mobility networks remain relatively stable.We also find that the low levels of mobility resilience in female,adolescent and older adult groups are mainly due to their insufficient capabilities to maintain business-as-usual travel frequency during the flood.Most importantly,we reveal three types of counter-intuitive,yet widely existing,resilience patterns of human mobility(namely,‘reverse bathtub’,‘ever-increasing’and‘ever-decreasing’patterns),and demonstrate a universal mechanism of disaster-avoidance response by further corroborating that those abnormal resilience patterns are not associated with people’s gender or age.In view of the common association between travel behaviors and travelers’socio-demographic characteristics,our findings provide a caveat for scholars when disclosing disparities in human travel behaviors during flood-induced emergencies.Junqing Tang Pengjun Zhao Zhaoya Gong Hongbo Zhao Fengjue Huang Jiaying Li Zhihe Chen Ling Yu Jun Chen 2023National Science Review2023,10,8:1

10Effect of Multi-parameter Environmental Factors on Cucumber Leaf Surface Wetness显示文摘In this study, artificial leaf resistance was used to simulate leaf wetness. Specific to the solar greenhouse environment in Tianjin, microclimate monitoring equipment was installed for the collection of temperature group and humidity group data, as well as solar radiation and leaf wetness in the greenhouse. In order to reduce the complexity of multivariate factor prediction and ensure the richness of selected data types, correlation analysis was made to the 2 groups of data, screening 5 000 groups of data, including the humidity group data RH, RH_(20), RH_(40), temperature group data T, T_(20), T_(40), and solar radiation W. The data were then analyzed by principal component analysis, screening out 4 groups of principal components to show the leaf wetness index.Chunyang QIAN Jianchun WANG Fengju LI Zhiwen SONG Yan WANG 2019Agricultural Biotechnology2019,8,2:0
11Cohort profile: design and methods of the Chinese colorectal, breast, lung, liver, and stomach cancer screening trial(C-BLAST)显示文摘Given the rapid changes in social structure(urbanization),economic structure(industrialization),and demographic structure(population aging)in China,cancer has become a major public health problem1.Extensive evidence has indicated that screening can decrease cancer mortality,particularly among high-risk groups,and several representative national and regional cancer screening programs have been launched in China to cope with the increasing burden of cancer.Yubei Huang Zhangyan Lyu Yu Zhang Xiaomin Liu Yacong Zhang Ya Liu Chao Sheng Hongyuan Duan Zeyu Fani Chenyang Li Xiao Lin Zhuowei Feng Lu Zheng Zhaoxiang Ye Hong Lu Ying Zhu Dejun Zhou Xi Wei Li Ren Bin Meng Fangfang Song Fengju Song Kexin Chen 2023Cancer Biology & Medicine2023,20,10:0
12Exploring the efficiency of image metric for assessing the visual quality of 3D mesh model显示文摘Recent developments in 3D graphics technology have led to extensive processes on 3D meshes(e.g.,compression,simplification,transmission and watermarking),these processes unavoidably cause the visual perceptual degradation of the 3D objects.The existing mesh visual quality evaluation metrics either require topology constrain or fail to reflect the perceived visual quality.Meanwhile,for the 3D objects that are observed on 2D screens by the users,it is reasonable to apply image metric to assess the distortion caused by mesh simplification.We attempt to explore the efficiency of image metric for assessing the visual fidelity of the simplified 3D model in this paper.For this purpose,several latest and most effective image metrics,2D snapshots,number and pooling algorithms are involved in our study,and finally tested on the IEETA simplification database.The statistical data allow the researcher to select the optimal parameter for this image-based mesh visual quality assessment and provide a new perspective for the design and performance assessment of mesh simplification algorithms.Li Che Fengju Kang 2018International Journal of Modeling, Simulation, and Scientific Computing2018,9,6:0
13Researches on preconditioned wire arrayZpinches in Xi’an Jiaotong University显示文摘The dynamics of wire array Z pinches are greatly affected by the initial state of the wires,which can be preconditioned by a prepulse current.Recent advances in experimental research on preconditioned wire array Z pinches at Xi’an Jiaotong University are presented in this paper.Single-wire explosion experiments were carried out to check the state of the preconditioning and to obtain the current parameters needed for wire gasification.Double-wire explosion experiments were conducted to investigate the temporal evolution of the density distribution of the two gasified wires.Based on the results of these experiments,a double-pulse Z-pinch facility,Qin-1,in which a 10 kA prepulse current was coupled with the 0.8 MA main current was designed and constructed.Wire arrays of different wire materials,including silver and tungsten,can be preconditioned by the prepulse current to a gaseous state.Implosion of the two preconditioned aluminum wires exhibited no ablation and little trailing mass.Jian Wu Yihan Lu Fengju Sun Xiaofeng Jiang Zhiguo Wang Daoyuan Zhang Xingwen Li Aici Qiu 2019Matter and Radiation at Extremes2019,4,3:0
14Improved diagnosis of thyroid cancer aided with deep learning applied to sonographic text reports:a retrospective,multi-cohort,diagnostic study显示文摘Objective:Large volume radiological text data have been accumulated since the incorporation of electronic health record(EHR)systems in clinical practice.We aimed to determine whether deep natural language processing algorithms could aid radiologists in improving thyroid cancer diagnosis.Methods:Sonographic EHR data were obtained from the EHR database.Pathological reports were used as the gold standard for diagnosing thyroid cancer.We developed thyroid cancer diagnosis based on natural language processing(THCaDxNLP)to interpret unstructured sonographic text reports for thyroid cancer diagnosis.We used the area under the receiver operating characteristic curve(AUROC)as the primary metric to measure the performance of the THCaDxNLP.We compared the performance of thyroid ultrasound radiologists aided with THCaDxNLP vs.those without THCaDxNLP using 5 independent test sets.Results:We obtained a total number of 788,129 sonographic radiological reports.The number of thyroid sonographic data points was 132,277,18,400 of which were thyroid cancer patients.Among the 5 test sets,the numbers of patients per set were 439,186,82,343,and 171.THCaDxNLP achieved high performance in identifying thyroid cancer patients(the AUROC ranged from 0.857–0.932).Thyroid ultrasound radiologists aided with THCaDxNLP achieved significantly higher performances than those without THCaDxNLP in terms of accuracy(93.8%vs.87.2%;one-sided t-test,adjusted P=0.003),precision(92.5%vs.86.0%;P=0.018),and F1 metric(94.2%vs.86.4%;P=0.007).Conclusions:THCaDxNLP achieved a high AUROC for the identification of thyroid cancer,and improved the accuracy,sensitivity,and precision of thyroid ultrasound radiologists.This warrants further investigation of THCaDxNLP in prospective clinical trials.Qiang Zhang Sheng Zhang Jianxin Li Yi Pan Jing Zhao Yixing Feng Yanhui Zhao Xiaoqing Wang Zhiming Zheng Xiangming Yang Lixia Liu Chunxin Qin Ke Zhao Xiaonan Liu Caixia Li Liuyang Zhang Chunrui Yang Na Zhuo Hong Zhang Jie Liu Jinglei Gao Xiaoling Di Fanbo Meng Wei Ji Meng Yang Xiaojie Xin Xi Wei Rui Jin Lun Zhang Xudong Wang Fengju Song Xiangqian Zheng Ming Gao Kexin Chen Xiangchun Li 2022Cancer Biology & Medicine2022,19,5:0
15Identification and validation of stable quantitative trait loci for yield component traits in wheat显示文摘Grain weight and grain number are important yield component traits in wheat and identification of underlying genetic loci is helpful for improving yield.Here,we identified eight stable quantitative trait loci(QTL)for yield component traits,including five loci for thousand grain weight(TGW)and three for grain number per spike(GNS)in a recombinant inbred line population derived from cross Yangxiaomai/Zhongyou 9507 across four environments.Since grain size is a major determinant of grain weight,we also mapped QTL for grain length(GL)and grain width(GW).QTGW.caas-2D,QTGW.caas-3B,QTGW.caas-5A and QTGW.caas-7A.2 for TGW co-located with those for grain size.QTGW.caas-2D also had a consistent genetic position with QGNS.caas-2D,suggesting that the pleiotropic locus is a modulator of trade-off effect between TGW and GNS.Sequencing and linkage mapping showed that TaGL3-5A and WAPO-A1 were candidate genes of QTGW.caas-5A and QTGW.caas-7A.2,respectively.We developed Kompetitive allele specific PCR(KASP)markers linked with the stable QTL for yield component traits and validated their genetic effects in a diverse panel of wheat cultivars from the Huang-Huai River Valley region.KASP-based genotyping analysis further revealed that the superior alleles of all stable QTL for TGW but not GNS were subject to positive selection,indicating that yield improvement in the region largely depends on increased TGW.Comparative analyses with previous studies showed that most of the QTL could be detected in different genetic backgrounds,and QTGW.caas-7A.1 is likely a new QTL.These findings provide not only valuable genetic information for yield improvement but also useful tools for marker-assisted selection.Lingli Li Yingjie Bian Yan Dong Jie Song Dan Liu Jianqi Zeng Fengju Wang Yong Zhang Zhonghu He Xianchun Xia Yan Zhang Shuanghe Cao 2023The Crop Journal2023,11,2:0
16Postoperative changes in corneal epithelial and stromal thickness profiles after SMILE in high myopic eyes显示文摘Background:To observe changes in the epithelial and stromal thickness after small incision refractive lenticule extraction(SMILE)and investigate their relationship with the different refractive error.Methods:One hundred and eighty eyes of 90 patients with a manifest refraction spherical equivalent(MRSE)of-6.36±1.53 diopters(D)were included.The eyes were assigned to the moderate myopic group(MRSE-3.00 to-6.00 D),high myopic group(MRSE-6.00 to-8.00 D)and super-high myopic group(MRSE above-8.00 D).The spectral-domain optical coherence tomography(SD-OCT)measured corneal and epithelial thickness in 17 zones preoperatively and 1,3,and 6 months postoperatively.Stromal thickness was calculated by subtracting the epithelial thickness from the total corneal thickness.The observed changes were correlated with the degree of myopia corrected.Results:MRSE showed significant differences between 3 and 6 months in the super-high myopic group(P=0.024).At 6 months,a statistically significant epithelial thickness increase was observed in the central zone(7.18%for moderate,10.23%for high,and 13.76%for super-high myopia,P<0.05 for all groups).The peripheral thickness decreased between 3 and 6 months in the high myopia and super-high myopia groups(P<0.05,respectively).A positive correlation between MRSE corrected and the postoperative epithelial thickening was observed in the central(r2=0.551,P<0.05).Compared to 1 month values,the central stromal thickness showed a decrease(3.2±4.5μm)at 3 months and an increase(4.4±4.9μm)at 6 months.The stroma thickened in moderate and high myopic groups but the thickness reduction were in super-high myopia group at 6 months paracentrally and peripherally.Conclusions:Significant thickness changes in the epithelium and stroma were detected during the 6 months after SMILE.Preliminary results suggest that epithelial and stromal thickness profile changes after SMILE may have an impact on the refractive outcome in the long-term postoperative period,especially in super-higher degrees of myopia.Dan Wang Ning Guo Yu Li Yan Zheng Fengju Zhang 2021Annals of Eye Science2021,,1:0
17UUV formation system modeling and simulation research based on Multi-Agent Interaction Chain显示文摘Unmanned Underwater Vehicle(UUV)formation system has an important role in the utilization of marine resource.In order to provide an efficient method to research modeling and simulation of UUV formation in the marine environment,the novel approach based on Multi-Agent Interaction Chain was proposed for the UUV formation system.Firstly,Multi-Agent Interaction Chain was analyzed,which mainly considered task and role of UUV in the formation,and the overall modeling process of UUV formation system based on Multi-Agent Interaction Chain was established.Then,the static structure of Multi-Agent Interaction Chain was researched focusing on Hybrid UUV-Agent model structure from the UUV-Agent State-Set and UUV-Agent Rule-Base which were the two aspects to strengthen reliability of interaction chain;the dynamic mechanism of Multi-Agent Interaction Chain was designed,which was focused on collaboration model and communication model through the Adaptive Dynamic Contract Net Protocol and KQML/XML/RTI.Finally,three experiments were established to verify the validity and effectiveness of proposed modeling approach for UUV formation system.Simulation results show the proposed model has good performance,which has important theoretical innovation and application prospects.Hongtao Liang Fengju Kang Honghong Li 2015International Journal of Modeling, Simulation, and Scientific Computing2015,6,2:0
