| 1 | Temperature rise and flow of Zr-based bulk metallic glasses under high shearing stress显示文摘Deformation of the bulk metallic glasses (BMGs) and the creation and propagation of the shear bands are closely interconnected.Shearing force was loaded on Zr 41.2 Ti 13.8 Cu 12.5 Ni 10.0 Be 22.5 (Vit.1) BMGs by cutting during the turning of the BMG rod.The temperature rise of alloy on the shear bands was calculated and the result showed that it could reach the temperature of the super-cooled liquid zone or exceed the melting point.The temperature rise caused viscous fluid flow and brought about the deformation of BMGs.This suggested that the deformation of BMGs was derived,at least to some extent,from the adiabatic shear temperature rise. | ZHANG WeiGuo MA MingZhen SONG AiJun LIANG ShunXing HAO QiuHong TAN ChunLin JING Qin LIU RiPing | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，11： | 2 |

| 3 | Climate change and water security in the northern slope of the Tianshan Mountains显示文摘Water security is under threat worldwide from climate change. A warming climate would accelerate evaporationand cryosphere melting, leading to reduced water availability and unpredictable water supply. However, thewater crisis in the Northern Slope of Tianshan Mountains(NSTM) faces dual challenges because water demandsforfast-growing urban areas have put heavy pressure on water resources. The mountain-oasis-desert system featuresglacier-fed rivers that sustain intensive water use in the oasis and end in the desert as fragile terminal lakes.The complex balance between water conservation and economic development is subtle. This paper investigateschanges in hydroclimatic variables and water security-related issues on the NSTM. The spatiotemporal variationsin glaciers, climatic variables, rivers, lakes and reservoirs, groundwater, surface water, human water use, andstreamflow were analyzed for the past four decades. The results show that temperature in the NSTM exhibitedan apparent upward trend with a more significant warming rate in the higher altitude regions. Glacier massloss and shrinkage was strong. The average annual streamflow increased from 1980-1989 to 2006–2011 at mosthydrological stations. The monthly dynamics of surface water area showed notable variability at both inter-annual and seasonal scales, revealing the impacts of both natural and anthropogenic drivers on surface wateravailability in the region. The terrestrial water storage anomaly showed a decreasing trend, which might berelated to groundwater pumping for irrigation. Human water use for agriculture and industry grew with theincrease in cultivated land area and gross domestic product (GDP). The increased agricultural water use wasstrongly associated with the expansion of oases. It is unclear whether water availability would remain high underfuture climatic and hydrological uncertainties, posing challenges to water management. In the context of rapidurban growth and climate change, balancing water for humans and nature is vital in achieving the SustainableDevelopment Goals (SDGs) in NSTM. This study provides a baseline understanding of the interplay among water,climate change, and socio-economic development in NSTM. It would also shed light on wise water managementunder environmental changes for other rapidly developing mountain-oasis-desert systems worldwide. | Qiuhong Tang Xingcai Liu Yuanyuan Zhou Puyu Wang Zhongqin Li Zhixin Hao Suxia Liu Gang Zhao Bingqi Zhu Xinlin He Fadong Li Guang Yang Li He Haoxin Deng Zongxia Wang Xiang Ao Zhi Wang Paul P.J.Gaffney Lifeng Luo | 2022 | Geography and Sustainability2022，3，3： | 1 |
| 4 | RNA-seq analysis of Brachypodium distachyon responses to Barley stripe mosaic virus infection显示文摘Barley stripe mosaic virus(BSMV) is the type member of the genus Hordeivirus. Brachypodium distachyon line Bd3-1 shows resistance to the BSMV ND18 strain, but is susceptible to an ND18 double mutant(βNDTGB1R390K, T392K) in which lysine is substituted for an arginine at position 390 and for threonine at position 392 of the triple gene block 1(TGB1) protein. In order to understand differences in gene expression following infection with ND18 and double mutant ND18, Bd3-1 seedlings were subjected to RNA-seq analyses at 1, 6, and14 days post inoculation(dpi). The results revealed that basal immunity genes involved in cellulose synthesis and pathogenesis-related protein biosynthesis were enhanced in incompatible interactions between Bd3-1 and ND18. Most of the differentially expressed transcripts are related to trehalose biosynthesis, ethylene, jasmonic acid metabolism,protein phosphorylation, protein ubiquitination, transcriptional regulation, and transport process, as well as pathogenesis-related protein biosynthesis. In compatible interactions between Bd3-1 and ND18 mutant, Bd3-1 developed weak basal resistance responses to the virus. Many genes involved in cellulose biosynthesis, protein amino acid phosphorylation,protein biosynthesis, protein glycosylation, glycolysis and cellular macromolecular complex assembly that may be related to virus replication, assembly and movement were up-regulated. Some genes involved in oxidative stress responses were also up-regulated at14 dpi. BSMV ND18 mutant infection suppressed expression of genes functioning in regulation of transcription, protein kinase, cellular nitrogen compound biosynthetic process and photosynthesis. Differential expression patterns between compatible and incompatible interactions in Bd3-1 to the two BSMV strains provide important clues for understanding mechanism of resistance to BMSV in the model plant Brachypodium. | Guoxin Wang Ling Wang Yu Cui Meihua Yu Chen Dang Hao Wang Xuejiao Jin Lijie Yan Qiuhong Wu Dawei Li Zhiyong Liu | 2017 | The Crop Journal2017，5，1： | 0 |
| 5 | Altitudinal variations of hydraulic traits in Faxon fir(Abies fargesii var.faxoniana):Mechanistic controls and environmental adaptability显示文摘Global climate change has been seen to result in marked impacts on forest ecosystems such as accelerated tree mortality worldwide due to incidental hydraulic failure caused by intensified and more frequent occurrence of extreme drought and heat-waves.However,it is well understood how the tree hydrological strategies would adjust to environmental variability brough about by climate changes.Here we investigated the hydraulic adjustment as a mechanism of acclimation to different climate conditions along an altitudinal gradient in Faxon fir(Abies fargesii var.faxoniana)–a tree species that plays a key role in conservation of wildlife and maintenance of ecosystem services in subalpine forests.The hydraulic traits and selective morphological and physiological variables were measured seasonally along an altitudinal gradient from 2,800 to 3,600 m a.s.l.We found that the native percentage loss of conductivity(PLC)increased with altitude across the seasonal measurements.Both the native sapwood-specific hydraulic conductivity(Ks)and native leaf-specific hydraulic conductivity(Kl)significantly decreased with altitude for measurements in July and October,coinciding with the timing for peak growth and pre-dormancy,respectively.The morphological traits varied toward more conservative tree hydrological strategies with increases in altitude,exhibiting trade-offs with hydraulic traits.The total non-structural carbohydrates in both needle(NSCNeedle)and branch(NSCBranch)as well as photosynthetic capacity of current-year leaves played variable roles in maintaining the integrity of the hydraulic functioning and shaping the hydraulic adjustment under prevailing environmental conditions.Our findings indicate that Faxon fir possesses some degree of hydraulic adaptability to water limitation imposed by climate fluctuations in subalpine region through morphological and physiological modifications. | Shao-an Pan Guangyou Hao Xuhua Li Qiuhong Feng Xingliang Liu Osbert J.Sun | 2022 | Forest Ecosystems2022，9，3： | 0 |
| 6 | User Attribute Prediction Method Based on Stacking Multimodel Fusion显示文摘The user’s age and gender play a vital role within the user portrait.In view of the lack of basic attribute information,such as the age and gender of users,this paper constructs an attribute prediction method based on stacking multimodel integration.The user’s browsing and clicking history is analyzed to predict the user’s basic attributes.First,LR,RF,XGBoost,and ExtraTree were selected as the base classifiers for the first layer of the stacking framework,and the training results of the first layer were input as new training data into the second layer LightGBM for training.Experiments show that the proposed model can improve the accuracy of prediction results. | Qiuhong Chen Caimao Li Hao Lin Hao Li Yuquan Hou | 2022 | 国际计算机前沿大会会议论文集2022，，2： | 0 |

| 8 | Factorization Machine Based on Bitwise Feature Importance for CTR Prediction显示文摘Click-through-rate(CTR)prediction is a crucial task in recommendation systems.The accuracy of CTR prediction is strongly influenced by the precise extraction of essential data and the modeling strategy chosen.The data of the CTR task are often very sparse,and Factorization Machines(FMs)are a class of general predictors working effectively with it.However,the performance of FMs can be limited by the fixed feature representation and the same weight of different features.In this work,we propose an improved Bitwise Feature Importance Factorization Machine(BFIFM)to improve the accuracy.The necessity of learning the degree of effect of the same feature under various situations is learned through the low-order intersection method,and the deep neural network(DNN)in our model is used in parallel to study high-order intersections.According to the final results obtained,the BFIFM model significantly outperforms other state-of-the-art models. | Hao Li Caimao Li Yuquan Hou Hao Lin Qiuhong Chen | 2022 | 国际计算机前沿大会会议论文集2022，，1： | 0 |
| 9 | Focusing on the Importance of Features for CTR Prediction显示文摘TraditionalCTR recommendation models have concentrated on howto learn low-order and high-order characteristics.The majority of them make many efforts at combining low-order and high-order functions.However,they ignore the importance of the attentionmechanism for learning input features.The ECABiNet model is proposed in this article to enhance the performance of CTR.On the one hand,the ECABiNet model can learn the importance of features dynamically via the LayerNorm and ECANET layers.On the other hand,through the use of a biinteraction layer and a DNN layer,it is capable of effectively learning the feature interactions.According to the experimental results on two public datasets,the ECABiNet model is more effective than the previous CTR model. | Yuquan Hou Caimao Li Hao Li Hao Lin Qiuhong Chen | 2022 | 国际计算机前沿大会会议论文集2022，，1： | 0 |
| 10 | Comparison of viral propagation and drug response among SARS-CoV-2 VOCs using replicons capable of recapitulating virion assembly and release显示文摘Several variants of concern(VOCs)have emerged since the WIV04 strain of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)was first isolated in January 2020.Due to mutations in the spike(S)protein,these VOCs have evolved to enhance viral infectivity and immune evasion.However,whether mutations of the other viral proteins lead to altered viral propagation and drug resistance remains obscure.The replicon is a noninfectious viral surrogate capable of recapitulating certain steps of the viral life cycle.Although several SARS-CoV-2 replicons have been developed,none of them were derived from emerging VOCs and could only recapitulate viral genome replication and subgenomic RNA(sgRNA)transcription.In this study,SARS-CoV-2 replicons derived from the WIV04 strain and two VOCs(the Beta and Delta variants)were prepared by removing the S gene from their genomes,while other structural genes remained untouched.These replicons not only recapitulate viral genome replication and sgRNA transcription but also support the assembly and release of viral-like particles,as manifested by electron microscopic assays.Thus,the S-deletion replicon could recapitulate virtually all the post-entry steps of the viral life cycle and provides a versatile tool for measuring viral intracellular propagation and screening novel antiviral drugs,including inhibitors of virion assembly and release.Through the quantification of replicon RNA released into the supernatant,we demonstrate that viral intracellular propagation and drug response to remdesivir have not yet substantially changed during the evolution of SARS-CoV-2 from the WIV04 strain to the Beta and Delta VOCs. | Lingqian Tian Qiuhong Liu Rongjuan Pei Yingshan Chen Chonghui Xu Jielin Tang Hao Sun Kunpeng Liu Qi Yang Lei Yang Leshan Li Yongli Zhang Yuan Zhou Chao Shan Xue Hu Xinwen Chen Yun Wang | 2022 | Virologica Sinica2022，37，5： | 0 |
