| 1 | Summer atmospheric boundary layer structure in the hinterland of Taklimakan Desert, China显示文摘Understanding the characteristics of the structure of desert atmospheric boundary layer and its land surface process is of great importance to the simulations of regional weather and climate.To investigate the atmospheric boundary layer structure and its forming mechanism of Taklimakan Desert,and to improve the accuracy and precision of regional weather and climate simulations,we carried out a GPS radiosonde observation experiment in the hinterland of Taklimakan Desert from 25 June to 3 July,2015.Utilizing the densely observed sounding data,we analyzed the vertical structures of daytime convective boundary layer and nighttime stable boundary layer in summer over this region,and also discussed the impacts of sand-dust and precipitation events on the desert atmospheric boundary layer structure.In summer,the convective boundary layer in the hinterland of Taklimakan Desert developed profoundly and its maximum height could achieve 4,000 m;the stable boundary layer at nighttime was about 400–800-m thick and the residual mixing layer above it could achieve a thickness over 3,000 m.Sand-dust weather would damage the structures of nighttime stable boundary layer and daytime convective boundary layer,and the dust particle swarm can weak the solar radiation absorbed by the ground surface and further restrain the strong development of convective boundary layer in the daytime.Severe convective precipitation process can change the heat from the ground surface to the atmosphere in a very short time,and similarly can damage the structure of desert atmospheric boundary layer remarkably.Moreover,the height of atmospheric boundary layer was very low when raining.Our study verified the phenomenon that the atmospheric boundary layer with supernormal thickness exists over Taklimakan Desert in summer,which could provide a reference and scientific bases for the regional numerical models to better represent the desert atmospheric boundary layer structure. | WANG Minzhong WEI Wenshou HE Qing YANG Yuhui FAN Lei ZHANG Jiantao | 2016 | Journal of Arid Land2016,8,6: | 17 |
| 2 | Hydrology and water resources variation and its response to regional climate change in Xinjiang显示文摘Based on the surface runoff, temperature and precipitation data over the last 50 years from eight representative rivers in Xinjiang, using Mann-Kendall trend and jump detection method, the paper investigated the long-term trend and jump point of time series, the surface runoff, mean annual temperature and annual precipitation. Meanwhile, the paper analyzed the relationship between runoff and temperature and precipitation, and the flood frequency and peak flow. Results showed that climate of all parts of Xinjiang conformably has experienced an increase in temperature and precipitation since the mid-1980s. Northern Xinjiang was the area that changed most significantly followed by southern and eastern Xinjiang. Affected by temperature and precipitation variation, river runoff had changed both inter-annually and intra-annually. The surface runoff of most rivers has increased significantly since the early 1990s, and some of them have even witnessed the earlier spring floods, later summer floods and increasing flood peaks. The variation characteristics were closely related with the replenishment types of rivers. Flood frequency and peak flow increased all over Xinjiang. Climate warming has had an effect on the regional hydrological cycle. | XU Changchun CHEN Yaning YANG Yuhui HAO Xingming SHEN Yongping | 2010 | Journal of Geographical Sciences2010,20,4: | 17 |
| 3 | Spectral analysis and self-adjusting mechanism for oscillation phenomenon in hydrogen-oxygen continuously rotating detonation engine显示文摘The continuously rotating detonation engine(CRDE)is a new concept of engines for aircraft and spacecraft.Quasi-stable continuously rotating detonation(CRD)can be observed in an annular combustion chamber,but the sustaining,stabilizing and adjusting mechanisms are not yet clear.To learn more deeply into the CRDE,experimental studies have been carried out to investigate hydrogen-oxygen CRDE.Pressure histories are obtained during each shot,which show that stable CRD waves are generated in the combustor,when feeding pressures are higher than 0.5 MPa for fuel and oxidizer,respectively.Each shot can keep running as long as fresh gas feeding maintains.Close-up of the pressure history shows the repeatability of pressure peaks and indicates the detonation velocity in hydrogen–oxygen CRD,which proves the success of forming a stable CRD in the annular chamber.Spectrum of the pressure history matches the close-up analysis and confirms the CRD.It also shows multi-wave phenomenon and affirms the fact that in this case a single detonation wave is rotating in the annulus.Moreover,oscillation phenomenon is found in pressure peaks and a self-adjusting mechanism is proposed to explain the phenomenon. | Liu Yusi Wang Yuhui Li Yongsheng Li Yang Wang Jianping | 2015 | Chinese Journal of Aeronautics2015,28,3: | 14 |
| 4 | Carbon-supported Fe/Co-N electrocatalysts synthesized through heat treatment of Fe/Co-doped polypyrrole-polyaniline composites for oxygen reduction reaction显示文摘In this paper,we synthesized cathode catalysts(PANI-PPYR,Fe/PANI-PPYR,Co/PANI-PPYR and Fe-Co/PANI-PPYR)with high performance oxygen reduction by using a simple heat treatment process.These catalysts were fabricated by directly calcining the Fe and/or Co doped polyaniline(PANI)-polypyrrole(PPYR)composites.Their electrocatalytic activity for ORR both in acidic and in alkaline media was investigated by voltammetric techniques.Among the prepared catalysts,Co/PANI-PPYR presents the most positive ORR onset potential of 0.62 V(vs.SCE)in 0.5 mol/L H2SO4 solution or?0.09 V(vs.SCE)in 1 mol/L NaOH solution.In addition,the Co/PANI-PPYR catalyst shows the largest limiting-diffusion current density for ORR,which is 4.3 mA/cm2@0.2 V(vs.SCE)in acidic and 2.3 mA/cm2@?0.3 V(vs.SCE)in alkaline media.In acidic media,a four-electron reaction of ORR on the Co/PANI-PPYR and Fe/PANI-PPYR catalysts is more dominant than a two-electron reaction.In alkaline media,however,a four-electron and a two-electron mechanisms are co-present for the ORR on all the prepared catalysts.Co/PANI-PPYR catalyst also presents good electrocatalytic activity stability for ORR both in acidic and in alkaline media. | YI QingFeng ZHANG YuHui LIU XiaoPing YANG YaHui | 2014 | Science China Chemistry2014,57,5: | 8 |

| 7 | Efficacy and safety of low-dose interleukin-2 in combination with methotrexate in patients with active rheumatoid arthritis:a randomized,double-blind,placebo-controlled phase 2 trial显示文摘Rheumatoid arthritis(RA)is an aggressive autoimmune arthritis,and current therapies remain unsatisfactory due to low remission rate and substantially adverse effects.Low-dose interleukin-2(Ld-IL2)is potentially a therapeutic approach to further improve the disease.This randomized,double-blind,placebo-controlled trial was undertaken to evaluate the efficacy and safety of Ld-IL2 in patients with active RA.Patients were randomly assigned(1:1)to receive Ld-IL2,defined as a dose of 1 million IU,or placebo in a 12-week trial with a 12-week follow-up.Three cycles of Ld-IL2 or placebo were administered subcutaneously every other day for 2 weeks(a total of 7 doses),followed by a 2-week break.All patients received a stable dose of methotrexate(MTX).The primary outcomes were the proportion of patients achieving the ACR20,DAS28-ESR<2.6,and the change from baseline in CDAI or SDAI at week 24.Secondary endpoints included other clinical responses and safety.The primary outcomes were achieved in the perprotocol population.The improvements from baseline in CDAI and SDAI were significantly greater across time points for the LdIL2+MTX group(n=17)than for the placebo+MTX group(n=23)(P=0.018 and P=0.015,respectively).More patients achieved ACR20 response in the Ld-IL2+MTX group than those in the placebo+MTX group at week 12(70.6%vs 43.5%)and at week 24(76.5%vs 56.5%)(P=0.014).In addition,low Treg and high IL-21 were associated with good responses to Ld-IL2.Ld-IL-2 treatment was well-tolerated in this study.These results suggested that Ld-IL2 was effective and safe in RA.ClinicalTrials.gov number:NCT 02467504. | Xiaoying Zhang Miao Miao Ruijun Zhang Xu Liu Xiaozhen Zhao Miao Shao Tian Liu Yuebo Jin Jiali Chen Huixin Liu Xia Zhang Yun Li Yunshan Zhou Yue Yang Ru Li Haihong Yao Yanying Liu Chun Li Yuhui Li Limin Ren Yin Su Xiaolin Sun Jing He Zhanguo Li | 2022 | Signal Transduction and Targeted Therapy2022,7,4: | 7 |
| 8 | Molecular Cytogenetic Characterization of a Wheat-Leymus mollis 3D(3Ns) Substitution Line with Resistance to Leaf Rust显示文摘Leymus mollis(Trin.)Pilger(NsNsXmXm,2n?28),a wild relative of common wheat,possesses many potentially valuable traits that could be transferred to common wheat during breeding programs.In this study,the karyotypic constitution of a wheat e L.mollis 3D(3Ns#1)disomic substitution line isolated from the F5progeny of octoploid Tritileymus M842-16 Triticum durum cv.D4286,which was designated as 10DM57,was determined using genomic in situ hybridization(GISH),fluorescent in situ hybridization(FISH),SSR markers,and ESTSTS markers.Screening of mitosis and meiosis showed that 10DM57 had a chromosome karyotype of 2n?42?21II.GISH indicated that10DM57 was a line with 40 chromosomes from wheat and two of the Ns chromosomes from L.mollis,which formed a ring bivalent in pollen mother cells at metaphase I.FISH analysis showed that the chromosome 3D may be replaced by 3Ns#1 in 10DM57.DNA markers,including SSR and EST-STS primers,showed that the pair of wheat chromosome 3D in 10DM57 was substituted by the pair of chromosome 3Ns#1from L.mollis.Evaluation of the agronomic traits showed that,compared with its common wheat relative 7182,10DM57 was resistant to leaf rust while the spike length and number of spikes per plant were improved significantly,which correlated with a higher wheat yield.The new germplasm,10DM57,could be exploited as an intermediate material in wheat genetic and breeding programs. | Yuhui Pang Xinhong Chen Jixin Zhao Wanli Du Xueni Cheng Jun Wu Yanli Li Liangming Wang Jing Wang Qunhui Yang | 2014 | Journal of Genetics and Genomics2014,41,4: | 6 |
| 9 | Impacts of Climatic Change on River Runoff in Northern Xinjiang of China over Last Fifty Years显示文摘The characteristics of climatic change and river runoff, as well as the response of river runoff to climatic change in the northern Xinjiang are analyzed on the basis of the hydrological and meteorological data over the last 50 years by the methods of Mann-Kendall nonparametric test and the nonlinear regression model. The results show that: 1) The temperature and the precipitation increased significantly in the whole northern Xinjiang, but the precipitation displayed no obvious change, or even a decreasing trend in the northern mountainous area of the northern Xinjiang. 2) River runoff varied in different regions in the northern Xinjiang. It significantly increased in the northern slope of the Tianshan Mountains and the north of the northern Xinjiang (p = 0.05), while slightly increased in the west of the northern Xinjiang. 3) North Atlantic Oscillation (NAO) affects river runoff by influencing temperature and precipitation. The NAO and precipitation had apparent significant correlations with the river runoff, but the temperature did not in the northern Xinjiang. Since the mid-1990s river runoff increase was mainly caused by the increasing temperature in the northern slope of the Tianshan Mountains and the north of the northern Xinjiang. Increased precipitation resulted in increased river runoff in the west of the northern Xinjiang. | YANG Yuhui CHEN Yaning LI Weihong WANG Minzhong SUN Guili | 2010 | Chinese Geographical Science2010,20,3: | 6 |
| 10 | Research on Mobile Internet Mobile Agent System Dynamic Trust Model for Cloud Computing显示文摘This paper analyzes the reasons for the formation of security problems in mobile agent systems, and analyzes and compares the security mechanisms and security technologies of existing mobile agent systems from the perspective of blocking attacks. On this basis, the host protection mobile agent protection technology is selected, and a method to enhance the security protection of mobile agents (referred to as IEOP method) is proposed. The method first encrypts the mobile agent code using the encryption function, and then encapsulates the encrypted mobile agent with the improved EOP protocol IEOP, and then traces the suspicious execution result. Experiments show that using this method can block most malicious attacks on mobile agents, and can protect the integrity and confidentiality of mobile agents, but the increment of mobile agent tour time is not large. | Weijin Jiang Yang Wang Yirong Jiang Jiahui Chen Yuhui Xu Lina Tan | 2019 | China Communications2019,16,7: | 5 |
| 11 | Molecular toxicity of earthworms induced by cadmium contaminated soil and biomarkers screening显示文摘Earthworms(Eisenia fetida) were used to study the impact of low-dose cadmium in treated artificial soil(0,0.6,3,6,15,30 mg/kg) and contaminated natural soil(1.46 mg/kg).The changes of earthworms' physiological related gene expressions of metallothionein(MT),annetocin,calreticulin and antimicrobial peptides were detected using real-time PCR after a 70-day incubation period.The results showed that low doses of cadmium could up regulate earthworms' MT and down regulate annetocin gene expression and show a significant positive and negative correlation respectively.The expression of two other genes,calreticulin and anti-microbial peptides,was induced at low doses of cadmium(highest gene expression at 0.6 mg/kg for calreticulin and 6 mg/kg for anti-microbial peptides) and inhibited at high doses.No significant correlation was found for these two genes.This study shows that MT and annetocin genes expression found in earthworms in contaminated soil have the potential to be developed as biomarkers of soil cadmium pollution. | Xiaohui Mo Yuhui Qiao Zhenjun Sun Xiaofei Sun Yang Li | 2012 | Journal of Environmental Sciences2012,24,8: | 4 |
| 12 | Non-contact tensile viscoelastic characterization of microscale biological materials显示文摘Many structures and materials in nature and physiology have important 'meso-scale' structures at the micron lengthscale whose tensile responses have proven difficult to characterize mechanically. Although techniques such as atomic force microscopy and micro-and nano-identation are mature for compression and indentation testing at the nano-scale, and standard uniaxial and shear rheometry techniques exist for the macroscale, few techniques are applicable for tensile-testing at the micrometre-scale, leaving a gap in our understanding of hierarchical biomaterials. Here, we present a novel magnetic mechanical testing(MMT) system that enables viscoelastic tensile testing at this critical length scale. The MMT system applies non-contact loading, avoiding gripping and surface interaction effects. We demonstrate application of the MMT system to the first analyses of the pure tensile responses of several native and engineered tissue systems at the mesoscale, showing the broad potential of the system for exploring micro-and meso-scale analysis of structured and hierarchical biological systems. | Yuhui Li Yuan Hong Guang-Kui Xu Shaobao Liu Qiang Shi Deding Tang Hui Yang Guy M.Genin Tian Jian Lu Feng Xu | 2018 | Acta Mechanica Sinica2018,34,3: | 3 |
| 13 | Effect of Lactobacillus salivarius H strain isolated from Chinese dry-cured ham on the color stability of fresh pork显示文摘The aim of this research is to investigate the effect of lactic acid bacteria(LAB)on color stability of fresh pork.Of the seven LAB strains isolated from the Chinese dry-cured hams,H strain was identified as Lactobacillus salivarius(CCTCC M2010374)by serial biochemical tests and 16S rRNA analysis.The fresh pork samples were immersed in the H strain and Lactobacillus fermentum extracts for 1 min after ultrasonic cells disruption and samples immersed in sterile 0.9%(m/V)saline was served as a control group,then samples were vacuum packaged and stored at 4◦C.Nitrate oxide synthase(NOS)and metmyoglobin(MetMb)reductase were found in the cells extracts of H strain.After 6 days of storage,H strain group was found to be associated with the highest CIE a*values(P<0.05)and the lowest MetMb(41%).L.salivarius H strain has thus shown a beneficial effect on the color stability of fresh pork.Further research is necessary to elucidate its mechanism.©2013 Beijing Academy of Food Sciences.Production and hosting by Elsevier B.V.All rights reserved. | Zhen Luo Vincent Gasasira Yuhui Huang Dengyong Liu Xihong Yang Shihong Jiang Wenfeng Hu | 2013 | Food Science and Human Wellness2013,2,3: | 3 |
| 14 | A New Time-Aware Collaborative Filtering Intelligent Recommendation System显示文摘Aiming at the problem that the traditional collaborative filtering recommendation algorithm does not fully consider the influence of correlation between projects on recommendation accuracy,this paper introduces project attribute fuzzy matrix,measures the project relevance through fuzzy clustering method,and classifies all project attributes.Then,the weight of the project relevance is introduced in the user similarity calculation,so that the nearest neighbor search is more accurate.In the prediction scoring section,considering the change of user interest with time,it is proposed to use the time weighting function to improve the influence of the time effect of the evaluation,so that the newer evaluation information in the system has a relatively large weight.The experimental results show that the improved algorithm improves the recommendation accuracy and improves the recommendation quality. | Weijin Jiang Jiahui Chen Yirong Jiang Yuhui Xu Yang Wang Lina Tan Guo Liang | 2019 | Computers, Materials & Continua2019,,8: | 3 |

| 16 | Measuring loblolly pine crowns with drone imagery through deep learning显示文摘In modeling forest stand growth and yield,crown width,a measure for stand density,is among the parameters that allows for estimating stand timber volumes.However,accurately measuring tree crown size in the field,in particular for mature trees,is challenging.This study demonstrated a novel method of applying machine learning algorithms to aerial imagery acquired by an unmanned aerial vehicle(UAV)to identify tree crowns and their widths in two loblolly pine plantations in eastern Texas,USA.An ortho mosaic image derived from UAV-captured aerial photos was acquired for each plantation(a young stand before canopy closure,a mature stand with a closed canopy).For each site,the images were split into two subsets:one for training and one for validation purposes.Three widely used object detection methods in deep learning,the Faster region-based convolutional neural network(Faster R-CNN),You Only Look Once version 3(YOLOv3),and single shot detection(SSD),were applied to the training data,respectively.Each was used to train the model for performing crown recognition and crown extraction.Each model output was evaluated using an independent test data set.All three models were successful in detecting tree crowns with an accuracy greater than 93%,except the Faster R-CNN model that failed on the mature site.On the young site,the SSD model performed the best for crown extraction with a coefficient of determination(R^(2))of 0.92,followed by Faster R-CNN(0.88)and YOLOv3(0.62).As to the mature site,the SSD model achieved a R^(2)as high as 0.94,follow by YOLOv3(0.69).These deep leaning algorithms,in particular the SSD model,proved to be successfully in identifying tree crowns and estimating crown widths with satisfactory accuracy.For the purpose of forest inventory on loblolly pine plantations,using UAV-captured imagery paired with the SSD object detention application is a cost-effective alternative to traditional ground measurement. | Xiongwei Lou Yanxiao Huang Luming Fang Siqi Huang Haili Gao Laibang Yang Yuhui Weng I.-K.uai Hung | 2022 | Journal of Forestry Research2022,33,1: | 3 |

| 18 | Ultrathin hexagonal boron nitride as a van der Waals,force initiator activated graphene for engineering efficient non-metal electrocatalysts of Li-CO_(2) battery显示文摘Reasonably regulating electronic coupling to promote charge transfer and exciton separation has been regarded a promising approach in catalysis.The material engineering of van der Waals heterojunction(vdWsH)based on two-dimensional(2D)materials would be a potential way to optimize the as-prepared extrinsic physicochemical characteristics.However,it was still an almost uncultivated land waiting for exploration in catalysis.Herein,we introduced the inert h-boron nitride(h-BN)in non-metal reduced graphene oxide(GN)catalysts and constructed BN-GN vdWsH.The theoretical calculation demonstrated that the h-BN can effectively modify the electronic properties of graphene.With the introduction of h-BN,the BN-GN vdWsH can obviously enhance the catalytic activity of Li-CO_(2) battery.The existence of BN-GN vdWsH can reduce the overpotential more than 700 mV compared with reduced graphene oxide during the CO_(2) reduction reaction(CO_(2)RR)and CO_(2) evolution reaction(CO_(2)ER),and it extended cyclic stability more than three times,which was one structure design made it work as a high efficient electrocatalyst,catalytic materials. | Zemin Sun Di Wang Liu Lin Yuhui Liu Mengwei Yuan Caiyun Nan Huifeng Li Genban Sun Xiaojing Yang | 2022 | Nano Research2022,15,2: | 3 |
| 19 | Development of T. aestivum L.eH. californicum Alien Chromosome Lines and Assignment of Homoeologous Groups of Hordeum californicum Chromosomes显示文摘Hordeum californicum(2n=2x=14, HH) is resistant to several wheat diseases and tolerant to lower nitrogen. In this study, a molecular karyotype of H. californicum chromosomes in the Triticum aestivum L. cv. Chinese Spring(CS)eH. californicum amphidiploid(2n=6x=56, AABBDDHH) was established. By genomic in situ hybridization(GISH) and multicolor fluorescent in situ hybridization(FISH) using repetitive DNA clones(pTa71, pTa794 and pSc119.2) as probes, the H. californicum chromosomes could be differentiated from each other and from the wheat chromosomes unequivocally. Based on molecular karyotype and marker analyses, 12 wheatealien chromosome lines, including four disomic addition lines(DAH1, DAH3, DAH5 and DAH6), five telosomic addition lines(MtH7L,MtH1 S, MtH1 L, DtH6 S and DtH6L), one multiple addition line involving H. californicum chromosome H2, one disomic substitution line(DSH4) and one translocation line(TH7S/1BL), were identified from the progenies derived from the crosses of CSeH. californicum amphidiploid with common wheat varieties. A total of 482 EST(expressed sequence tag) or SSR(simple sequence repeat) markers specific for individual H. californicum chromosomes were identified, and 47, 50, 45, 49, 21, 51 and 40 markers were assigned to chromosomes H1, H2, H3, H4, H5, H6 and H7, respectively. According to the chromosome allocation of these markers, chromosomes H2,H3, H4, H5, and H7 of H. californicum have relationship with wheat homoeologous groups 5, 2, 6, 3, and 1, and hence could be designated as 5Hc, 2Hc, 6Hc, 3Hcand 1Hc, respectively. The chromosomes H1 and H6 were designated as 7Hcand 4Hc, respectively, by referring to SSR markers located on rye chromosomes. | Yuhui Fang Jingya Yuan Zhangjun Wang Haiyan Wang Jin Xiao Zhixi Yang Ruiqi Zhang Zengjun Qi Weigang Xu Lin Hu Xiu-E Wang | 2014 | Journal of Genetics and Genomics2014,41,8: | 2 |
| 20 | Development and identification of a dwarf wheat-Leymus mollis double substitution line with resistance to yellow rust and Fusarium head blight显示文摘Leymus mollis (Trin.) Pilger (2n = 4x = 28, NsNsXmXm,), a wild relative of common wheat, possesses many potentially valuable traits for genetic improvement of wheat, including strong, short stems, long spikes with numerous spikelets, tolerance to drought and cold stresses, and resistance to many fungal and bacterial diseases. In the present study, a wheat-L. mollis double substitution line DM96 was selected from a F6 progeny of a cross between M842-16 (an octoploid Tritileymus line) and D4286 (a Triticum durum line) using genomic in situ hybridization (GISH), simple sequence repeat (SSR) markers, and expressed sequence tagged sequence site (EST-STS) markers. Chromosome analysis at mitosis and meiosis showed that DM96 had a chromosome constitution of 2n = 42 = 21II. GISH analysis indicated that DM96 carried 38 chromosomes from wheat and two homologous pairs of Ns chromosomes from L. mollis. Fluorescent in situ hybridization (FISH) showed that chromosomes 2Ns and 3Ns from L. mollis had replaced wheat chromosomes 2D and 3D in DM96, which was confirmed by SSR and STS markers. The newly developed substitution line DM96 has shorter height, longer spikes and more kernels than its parents and showed high resistance to stripe rust and Fusarium head blight (FHB). Thus, this line is a new bridge material for the production of useful translocation lines for wheat genetic research and genetic improvement of wheat yield and disease resistance in breeding programs. | Jixin Zhao Yang Liu Xueni Cheng Yuhui Pang Jiachuang Li Zhenqi Su Jun Wu Qunhui Yang Guihua Bai Xinhong Chen | 2019 | The Crop Journal2019,7,4: | 2 |
