| 1 | Quantum secure direct communication with cluster states显示文摘A quantum secure direct communication protocol with cluster states is proposed.Compared with the deterministic secure quantum communication protocol with the cluster state proposed by Yuan and Song(Int.J.Quant.Inform.,2009,7:689),this protocol can achieve higher intrinsic efficiency by using two-step transmission.The implementation of this protocol is also discussed. | CAO WeiFeng 1,YANG YuGuang 3,4,5* & WEN QiaoYan 2 1 College of Electric and Information Engineering,Zhengzhou University of Light Industry,Zhengzhou 450002,China 2 State Key Laboratory of Networking and Switching Technology,Beijing University of Posts and Telecommunications,Beijing 100876,China 3 College of Computer Science and Technology,Beijing University of Technology,Beijing 100124,China 4 State Key Laboratory of Integrated Services Network,Xidian University,Xi’an 710071,China 5 State key Laboratory of Information Security Gradute University of Chinese Academy of Sciences,Beijing 100049,China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，7： | 20 |
| 2 | A New Critical Nitrogen Dilution Curve for Rice Nitrogen Status Diagnosis in Northeast China显示文摘In-season diagnosis of crop nitrogen(N) status is crucial for precision N management. Critical N(N_c) dilution curve and N nutrition index(NNI) have been proposed as effective methods to diagnose N status of different crops. The N_c dilution curves have been developed for indica rice in the tropical and temperate zones and japonica rice in the subtropical-temperate zone, but they have not been evaluated for short-season japonica rice in Northeast China. The objectives of this study were to evaluate the previously developed N_c dilution curves for rice in Northeast China and to develop a more suitable N_c dilution curve in this region. A total of17 N rate experiments were conducted in Sanjiang Plain, Heilongjiang Province in Northeast China from 2008 to 2013. The results indicated that none of the two previously developed N_c dilution curves was suitable to diagnose N status of the short-season japonica rice in Northeast China. A new N_c dilution curve was developed and can be described by the equation N_c = 27.7 W^(-0.34) if W ≥ 1 Mg dry matter(DM) ha^(-1) or N_c = 27.7 g kg^(-1) DM if W < 1 Mg DM ha^(-1), where W is the aboveground biomass. This new curve was lower than the previous curves. It was validated using a separate dataset, and it could discriminate non-N-limiting and N-limiting nutritional conditions. Additional studies are needed to further evaluate it for diagnosing N status of different rice cultivars in Northeast China and develop efficient non-destructive methods to estimate NNI for practical applications. | HUANG Shanyu MIAO Yuxin CAO Qiang YAO Yinkun ZHAO Guangming YU Weifeng SHEN Jianning YU Kang Georg BARETH | 2018 | Pedosphere2018，28，5： | 10 |
| 3 | Antidepressant-Like Action of Single Facial Injection of Botulinum Neurotoxin A is Associated with Augmented 5-HT Levels and BDNF/ERK/CREB Pathways in Mouse Brain显示文摘The present study was designed to examine the therapeutic effects of Botulinum neurotoxin A(BoNT/A)on depression-like behaviors in mice and to explore the potential mechanisms.These results revealed that a single facial injection of BoNT/A induced a rapid and prolonged improvement of depression-like behaviors in naive and space-restriction-stressed(SRS)mice,reflected by a decreased duration of immobility in behavioral despair tests.BoNT/A significantly increased the 5-hydroxytryptamine(5-HT)levels in several brain regions,including the hippocampus and hypothalamus,in SRS mice.BoNT/A increased the expression of the N-methyl-Daspartate receptor subunits NR1 and NR2 B in the hippocampus,which were significantly decreased in SRS mice.Furthermore,BoNT/A significantly increased the expression of brain-derived neurotrophic factor(BDNF)in the hippocampus,hypothalamus,prefrontal cortex,and amygdala,which were decreased in SRS mice.Finally,BoNT/A transiently increased the levels of phosphorylated extracellular signal-regulated kinase(p-ERK)and cAMPresponse element binding protein(p-CREB),which were suppressed in the hippocampus of SRS mice.Collectively,these results demonstrated that BoNT/A treatment has antidepressant-like activity in mice,and this is associated with increased 5-HT levels and the activation of BDNF/ERK/CREB pathways in the hippocampus,supporting further investigation of BoNT/A therapy in depression. | Yang Li Jing Liu Xu Liu Cun-Jin Su Qi-Lin Zhang Zhi-Hong Wang Lei-Fang Cao Xue-Yan Guo Ya Huang Weifeng Luo Tong Liu | 2019 | Neuroscience Bulletin2019，35，4： | 10 |
| 4 | Rhizosheath formation and involvement in foxtail millet(Setaria italica) root growth under drought stress显示文摘The rhizosheath, a layer of soil particles that adheres firmly to the root surface by a combination of root hairs and mucilage, may improve tolerance to drought stress. Setaria italica(L.) P. Beauv.(foxtail millet), a member of the Poaceae family, is an important food and fodder crop in arid regions and forms a larger rhizosheath under drought conditions. Rhizosheath formation under drought conditions has been studied, but the regulation of root hair growth and rhizosheath size in response to soil moisture remains unclear. To address this question, in this study we monitored root hair growth and rhizosheath development in response to a gradual decline in soil moisture. Here, we determined that a soil moisture level of 10%–14%(w/w)stimulated greater rhizosheath production compared to other soil moisture levels. Root hair density and length also increased at this soil moisture level, which was validated by measurement of the expression of root hair-related genes.These findings contribute to our understanding of rhizosheath formation in response to soil water stress. | Tie-Yuan Liu Nenghui Ye Tao Song Yunying Cao Bei Gao Di Zhang Fuyuan Zhu Moxian Chen Yingjiao Zhang Weifeng Xu Jianhua Zhang | 2019 | Journal of Integrative Plant Biology2019，61，4： | 6 |
| 5 | Influence of particle composition on thorium scavenging in the marginal China seas显示文摘Thorium-234 and particle composition (organic matter, biogenic silica, carbonate and lithogenic component) were examined in the East China Sea (ECS) and the northern South China Sea (NSCS) in order to constrain the particle types scavenging thorium isotopes. Good positive correlations be-tween particulate organic matter (POM) or carbonate and thorium-234 in suspended particulate matter (SPM) indicates that POM and carbonate are efficient to scavenge thorium-234. No relation-ship between biogenic silica and thorium-234 suggests that geochemical behavior of thorium-234 may be not influenced by biogenic silica. A simple model was used to evaluate the affinity of thorium-234 to different particle components. The results show that POM is the most efficient scavenger for thorium-234 in the ECS and the NSCS, followed by carbonate. The authors’ re-sults lend support to the utility of thorium-234 as a proxy of POC and carbonate in the upper layer. However, the strong dependence of thorium scavenging on particle composition challenges thorium-230 as a constant flux proxy. | YANG Weifeng CHEN Min CAO Jianping QIU Yusheng ZHANG Run MA Qiang TONG Jinlu YANG Junhong YANG Zhi LUE E | 2009 | Acta Oceanologica Sinica2009，28，2： | 4 |

| 10 | Effects of bias voltage on coating structures and anticorrosion performances of PA-PVD Al coated NdFeB magnets显示文摘Al coated NdFeB magnets were prepared by plasma-assisted-physical-vapor-deposition(PA-PVD)method fo r enhancing the corro sion resistance.Mo rphologies and structures were characterized by an Xray diffractometer and a scanning electron microscope.Corrosion behaviors of the samples with different bias voltages were studied by electrochemical methods and neutral salt spray test,respectively.The bias voltage during the deposition process was optimized according to the coating structures and corrosion resistances.The density and flatness of Al coating increase with increasing the bias voltage,and at the same time the thickness decreases.The coating density and thickness turn to be stable when bias voltage is 1800 V.Also,the corrosion behaviors of PA-PVD Al coatings in different media,such as NaOH,HNO_(3) and NaCl solutions,were studied.The self-corrosion potentials(E_(corr)) of PA-PVD Al coatings almost keep constant in NaOH and HNO_(3) solutions with diffe rent concentrations.However,the self-corrosion current densities(J_(corr)) decrease with the increasing concentrations.E_(corr) shifts to negative potential and J_(corr)decreases gradually when increasing the concentration of NaCl solution.The corrosion mechanisms of Al coatings are discussed based on the corrosion behaviors in different media. | Yujie Cao Pengjie Zhang Wei Sun Weifeng Zhang Hanzhong Wei Jiquan Wang Bingshan Li Xiaofei Yi Guangqing Xu Yucheng Wu | 2021 | Journal of Rare Earths2021，39，6： | 2 |
| 11 | The leaf extract of crofton weed(Eupatorium adenophorum)inhibits primary root growth by inducing cell death in maize root border cells显示文摘The extract of crofton weed(Eupatorium adenophorum) inhibits seed germination and weed growth;however,the physiological mechanisms underlying the effect of crofton weed extract on the modulation of seedling growth and root system development remain largely unclear.In this study,we investigated the effects of the leaf extract of crofton weed(LECW) on primary root(PR) growth in maize seedlings.Treatment with LECW markedly inhibited seed germination and seedling growth in a dose-dependent manner.Physiological analysis indicated that the LECW induced reactive oxygen species(ROS) accumulation in root tips,thereby leading to cell swelling and deformation both in the root cap and elongation zone of root tips,finally leading to cell death in root border cells(RBCs) and PR growth inhibition.The LECW also inhibited pectin methyl esterase(PME) activity,thereby decreasing the RBC number.Taken together,our results indicated that the LECW inhibited PR growth by inducing ROS accumulation and subsequent cell death in RBCs.The present study provides a better understanding of how the LECW modifies root system development and provides insight for evaluating the toxicity of crofton weed extracts in plants. | Jinhu Ma Xinxin Feng Xiaohuan Yang Yongheng Cao Weifeng Zhao Liangliang Sun | 2020 | Plant Diversity2020，42，3： | 2 |
| 12 | Modeling for tungstic precipitation and extraction based on Pitzer equation显示文摘This work presented the results of tungstic precipitation from Na_2WO_4-Na_2SO_4-H_2O system at 293.15 K, with which the Pitzer parameters of β_(Na2WO4)^(0) and β(Na2WO4)^(1) were determined from Pitzer equation by regression. Thus the mean ionic activity coefficients of sodium tungstate were calculated. The obtained β_(Na2WO4)^(0) and β(Na2WO4)^(1) were substituted as fixed values in extraction modeling from Na_2WO_4-H_2SO_4-H_2O system by primary amine(N1923) in toluene as diluent. Meanwhile the activity coefficient expressions in organic phase were varied based on Pitzer theory that the interaction term for the solvent should not be included. The Pitzer parameters for organic phase were re-regressed in order to make the model more accurate. The average absolute relative deviation(AARD) for calculated and experimental molality of WO_4~(2-) in aqueous phase was 5.24%. The results showed that the model can not only correlate but also predict the liquid-liquid equilibrium(LLE) data. | Xinyue Zhang Pengge Ning Weifeng Xu Hongbin Cao Yi Zhang | 2016 | Science China Chemistry2016，59，4： | 2 |

| 14 | Thermodynamic models based on Pitzer-NRTL and Pitzer-Margules equations for the extraction of tungstic acid with primary amine N1923显示文摘The thermodynamic model of the extraction of W with primary amine under near neutral conditions is reported in this paper. The activity coefficients of the nonelectrolytes in organic phase are calculated by the Margules and NRTL equations which are based on previously tested liquid-liquid extraction equilibrium data in combination with mass balances and charge balance formula. The activity coefficients of the electrolytes in aqueous phase are calculated by the Pitzer equation. The thermodynamic model of the extraction of W by a primary amine is constructed from the calculated activity coefficients of electrolytes and nonelectrolytes. The extraction of W using primary amine is also predicated, and the data is compared to the calculated results of the thermodynamic model. It is concluded that Margules equation proves to be suitable and reliable for calculating the activity coefficients of nonelectrolytes in complex organic phase systems. | LIN Xiao NING PengGe XU WeiFeng CAO HongBin ZHANG Yi | 2015 | Science China(Technological Sciences)2015，58，5： | 1 |
| 15 | Three Novel Avastroviruses Identified in Dead Wild Crows显示文摘Dear Editor,Astroviruses(AstVs)are non-enveloped,single-stranded RNA viruses with a diameter of approximately 35 nm(Madeley and Cosgrove 1975).The genomes of AstVs range in size from 6.8 to 7.9 kb(De Benedictis et al.2011),consisting of a 5'-untranslated region(UTR),three open reading frames(ORFs),a 3'-UTR,and a poly-adenylated(polyA)tail(Pantin-Jackwood et al.2006).In 1975,AstVs were first discovered in faeces of infants(Madeley and Cosgrove 1975).Until now,a variety of animal species,including cows,sheep,pigs,dogs,deer,rats,bats,chickens,ducks,turkeys,sea lions and seals have been reported to be infected with AstVs(Tzipori et al.1981;Cattoli et al.2007;Chu et al.2008,2010;Atkins et al.2009;Toffan et al.2009;Rivera et al.2010;Guix et al.2013;Kang et al.2012;Reuter et al.2012a,2012b;Li et al.2021).Currently,AstVs comprise two genera,Mamastrovirus(MAstV)and Avastrovirus(AAstV).Herein,we describe three novel AAstVs identified from dead crow tissues.To our knowledge,this is the first report for identification of AstVs in crows. | Chunge Zhang Yongchun Yang Tao Hu Hong Zhou Cheng Zhang Jian Cao Juan Li Peihan Wang Gary Wong Xiaodu Wang Houhui Song George FGao Weifeng Shi Yuhai Bi | 2021 | Virologica Sinica2021，36，6： | 1 |

| 19 | Small extracellular vesicles with nanomorphology memory promote osteogenesis显示文摘Nanotopographical cues endow biomaterials the ability to guide cell adhesion, proliferation, and differentiation. Cellular mechanical memory can maintain the cell status by retaining cellular information obtained from past mechanical microenvironments. Here, we propose a new concept “morphology memory of small extracellular vesicles (sEV)” for bone regeneration. We performed nanotopography on titanium plates through alkali and heat (Ti8) treatment to promote human mesenchymal stem cell (hMSC) differentiation. Next, we extracted the sEVs from the hMSC, which were cultured on the nanotopographical Ti plates for 21 days (Ti8-21-sEV). We demonstrated that Ti8-21-sEV had superior pro-osteogenesis ability in vitro and in vivo. RNA sequencing further confirmed that Ti8-21-sEV promote bone regeneration through osteogenic-related pathways, including the PI3K-AKT signaling pathway, MAPK signaling pathway, focal adhesion, and extracellular matrix-receptor interaction. Finally, we decorated the Ti8-21-sEV on a 3D printed porous polyetheretherketone scaffold. The femoral condyle defect model of rabbits was used to demonstrate that Ti8-21-sEV had the best bone ingrowth. In summary, our study demonstrated that the Ti8-21-sEV have memory function by copying the pro-osteogenesis information from the nanotopography. We expect that our study will encourage the discovery of other sEV with morphology memory for tissue regeneration. | Liang Ma Wencan Ke Zhiwei Liao Xiaobo Feng Jie Lei Kun Wang Bingjin Wang Gaocai Li Rongjin Luo Yunsong Shi Weifeng Zhang Yu Song Weibin Sheng Cao Yang | 2022 | Bioactive Materials2022，7，11： | 1 |
| 20 | Rigid–flexible hybrid surfaces for water-repelling and abrasionresisting显示文摘Droplets impacting solid superhydrophobic surfaces is appealing not only because of scientific interests but also for technological applications such as water-repelling.Recent studies have designed artificial surfaces in a rigid–flexible hybrid mode to combine asymmetric redistribution and structural oscillation water-repelling principles,resolving strict impacting positioning;however,this is limited by weak mechanical durability.Here we propose a rigid–flexible hybrid surface(RFS)design as a matrix of concave flexible trampolines barred by convex rigid stripes.Such a surface exhibits a 20.1%contact time reduction via the structural oscillation of flexible trampolines,and even to break through the theoretical inertial-capillary limit via the asymmetric redistribution induced by rigid stripes.Moreover,the surface is shown to retain the above water-repelling after 1,000 abrasion cycles against oilstones under a normal load as high as 0.2 N·mm−1.This is the first demonstration of RFSs for synchronous waterproof and wearproof,approaching real-world applications of liquid-repelling. | Songtao HU Weifeng HUANG Jinbang LI Tom REDDYHOFF Xiaobao CAO Xi SHI Zhike PENG Andrew DEMELLO Daniele DINI | 2023 | Friction2023，11，4： | 0 |
