| 2 | Roles and Functions of Tourism Destinations in Tourism Region of South Anhui:A Tourist Flow Network Perspective显示文摘Theoretic and practical significance has been highlighted in the research of the roles and functions of destinations,as destinations are restricted by the spatial structure based on tourist flow network from the perspective of relationship.This article conducted an empirical analysis for Tourism Region of South Anhui(TRSA) and revealed the necessity and feasibility of studying the roles and functions of destinations from tourist flow network's perspective.The automorphic equivalence analysis and centrality analysis were used to classify 16 destinations in TRSA into six role types:tourist flow distribution center,hub of tourist flows,passageway destination,common touring destination,attached touring destination,and nearly isolated destination.Some suggestions were given on suitable infrastructure construction and destinations service designs according to their functions in network.This destination role positioning was based on tourist flow network structure in integral and macroscopic way.It provided an important reference for the balanced and harmonious development of all the destinations of TRSA.In addition,this article verified the applicability of social network analysis on tourist flow research in local scale,and expanded this method to destination role and function positioning. | LIU Fajian ZHANG Jinhe ZHANG Jie CHEN Dongdong LIU Zehua LU Song | 2012 | Chinese Geographical Science2012,22,6: | 8 |
| 3 | Effect of ZrO_2 Content on the Properties of Diamond Grinding Wheel Vitrified Bond显示文摘The effect of ZrO2 content on the performance of vitrified bond was discussed. The results showed that when the ZrO2 content was less than 2 mol%, Zr4+ could enter into the glassy network as mending nets and agglomeration composition. In this case, with the increasing of ZrO2, the vitrified bond's bending strength increased and the expansion coefficient decreased. It was also found that the wetting angle between the vitrified bond and diamond got small because Zr4+ was enriched on diamond surface. When ZrO2 content was more than 2 mol%, a part of ZrO2 existing in vitrified bond as ZrO2 particles played the role in nucleating agents and promoting the separation of spodumene. When ZrO2 content was 3 mol%, the bending strength of the vitrified bond reached its maximum of 128 MPa and the wetting angle with the diamond reached its minimum of 37.6°. | 刘小磐 QIAO Ang WAN Long HU Weida SONG Dongdong LI Zheng YIN Zhongjie 潘瑞琨 | 2014 | Journal of Wuhan University of Technology(Materials Science)2014,29,1: | 7 |
| 4 | Corrosion behavior of Al_(0.4)CoCu_(0.6)NiSi_(0.2)Ti_(0.25) high-entropy alloy coating via 3D printing laser cladding in a sulphur environment显示文摘High-entropy alloys(HEAs) are of great interest in materials science and engineering communities owing to their unique phase structure.HEAs are constructed with five or more principal alloying elements in equimolar or near-equimolar ratios.Therefore,they can derive their performance from multiple principal elements ratherthan a single element.In this work,three-dimensional printing laser cladding was applied to produce an Al_(0.4)CoCu_(0.6)NiSi_(0.2)Ti_(0.25) HEA coating.The experimental results confirmed that the laser cladding could be used to produce a thin coating of 120 μm in thickness.In the high-temperature laser cladding process,some Fe elements diffused from the substrate to the coating,forming a combination of face-centred cubic and body-centred cubic phase structures.The HEA coating metallurgically bonded well with the substrate.Owing to the increased dislocation density and number of grain boundaries,the HEA coating was harder and had a stronger hydrophobicity than X70 steel.The electrochemistry results showed that the HEA coating had better corrosion resistance than X70 steel.Aluminium oxides formed on the surface of the HEA coating had a certain protective effect.However,because of the laser cladding,the HEA coating generated cracks.In future work,the laser cladding technology will be improved and heat treatment will be implemented to prevent formation of cracks. | Hongxia Wan Dongdong Song Xiaolei Shi Yong Cai Tingting Li Changfeng Chen | 2021 | Journal of Materials Science & Technology2021,,1: | 6 |

| 6 | A transceptor-channel complex couples nitrate sensing to calcium signaling in Ambidopsis显示文摘Nitrate-induced Ca^(2+) signaling is crucial for the primary nitrate response in plants.However,the molecular mechanism underlying the generation of the nitrate-specific calcium signature remains unknown.We report here that a cyclic nucleotide-gated channel(CNGC)protein,CNGC15,and the nitrate transceptor(NRT1.1)constitute a molecular switch that controls calcium influx depending on nitrate levels.The expression of CNGC15 is induced by nitrate,and its protein is localized at the plasma membrane after establishment of young seedlings.We found that disruption of CNGC15 results in the loss of the nitrate-induced Ca^(2+) signature(primary nitrate response)and retards root growth,reminiscent of the phenotype observed in the nrt1.1 mutant.We further showed that CNGC15 is an active Ca^(2+)-permeable channel that physically interacts with the NRT1.1 protein in the plasma membrane.Importantly,we discovered that CNGC15-NRT1.1 interaction silences the channel activity of the heterocomplex,which dissociates upon a rise in nitrate levels,leading to reactivation of the CNGC15 channel.The dynamic interactions between CNGC15 and NRT1.1 therefore control the channel activity and Ca^(2+) influx in a nitrate-dependent manner.Our study reveals a new nutrient-sensing mechanism that utilizes a nutrient transceptor-channel complex assembly to couple nutrient status to a specific Ca^(2+) signature. | Xiaohan Wang Changxin Feng LiLi Tian Congcong Hou Wang Tian Bin Hu Qian Zhang Zhijie Ren Qi Niu Jiali Song Dongdong Kong Liangyu Liu Yikun He Ligeng Ma Chengcai Chu Sheng Luan Legong Li | 2021 | Molecular Plant2021,14,5: | 5 |
| 7 | Joints of continuous carbon fiber reinforced lithium aluminosilicate glass ceramics matrix composites to Ti60 alloy brazed using Ti-Zr-Ni-Cu active alloy显示文摘Continuous carbon fiber reinforced lithium aluminosilicate glass ceramics matrix composites(C_f/LAS composites) are joined to Ti60 alloy vacuum brazed using Ti-Zr-Ni-Cu brazing alloy. The effects of the brazing temperature on the interfacial microstructure and mechanical properties of brazed joints are investigated in details. The interfacial microstructure varies apparently with an increase of the brazing temperature. The thicknesses of the banded Ti solid solution(Ti(s, s)) and the reactive layer between Cf/LAS composites and the interlayer grow gradually. The mechanical properties of brazed joints increase firstly and then decrease with an increasing temperature. In addition, a joint that is brazed at 980 °C for 10 min shows the highest shear strength of$38.13 MPa. At the same time, the fracture paths of brazed joints also change as the temperature increases. When the brazing temperature is 950 °C, the fracture position is in the TiC + ZrC +Ti_2O + ZrSi_2+ Ti_5Si_3 layer on the composite side. When the brazing temperature is 980 °C, the fracture position is on the side of the braze seam(Ti, Zr)2(Ni, Cu), Ti_2O + ZrSi_2+ Ti_5Si_3 layer,and carbon fiber in the composite material. When the brazing temperature is 990 °C, the fracture position is in the Ti_2O + ZrSi_2+ Ti_5Si_3 layer on the composite side and the carbon fiber in the composite material. | Shengpeng HU Dongdong FENG Long XIA Ke WANG Renwei LIU Zhentao XIA Hongwei NIU Xiaoguo SONG | 2019 | Chinese Journal of Aeronautics2019,32,3: | 4 |
| 8 | Ferrimagnetic m PEG-b-PHEP copolymer micelles loaded with iron oxide nanocubes and emodin for enhanced magnetic hyperthermia–chemotherapy显示文摘As a non-invasive therapeutic method without penetration-depth limitation,magnetic hyperthermia therapy(MHT)under alternating magnetic field(AMF)is a clinically promising thermal therapy.However,the poor heating conversion efficiency and lack of stimulus–response obstruct the clinical application of magnetofluid-mediated MHT.Here,we develop a ferrimagnetic polyethylene glycol-poly(2-hexoxy-2-oxo-1,3,2-dioxaphospholane)(m PEG-b-PHEP)copolymer micelle loaded with hydrophobic iron oxide nanocubes and emodin(denoted as EMM).Besides an enhanced magnetic resonance(MR)contrast ability(r2=271 m M^-1 s^-1)due to the high magnetization,the specific absorption rate(2518 W/g at 35 k A/m)and intrinsic loss power(6.5 n Hm2/kg)of EMM are dozens of times higher than the clinically available iron oxide nanoagents(Feridex and Resovist),indicating the high heating conversion efficiency.Furthermore,this composite micelle with a flowable core exhibits a rapid response to magnetic hyperthermia,leading to an AMF-activated supersensitive drug release.With the high magnetic response,thermal sensitivity and magnetic targeting,this supersensitive ferrimagnetic nanocomposite realizes an above 70%tumor cell killing effect at an extremely low dosage(10μg Fe/m L),and the tumors on mice are completely eliminated after the combined MHT–chemotherapy. | Yonghong Song Dongdong Li Yang Lu Kun Jiang Yi Yang Yunjun Xu Liang Dong Xu Yan Daishun Ling Xianzhu Yang Shu-Hong Yu | 2020 | National Science Review2020,7,4: | 4 |

| 10 | Hd1,Ghd7,and DTH8 synergistically determine the rice heading date and yield-related agronomic traits显示文摘Heading date determines the seasonal and regional adaptation of rice(Oryza sativa L.)varieties and is mainly controlled by photoperiod sensitivity(PS).The core heading date genes Hd1,Ghd7,DTH8,and PRR37 act synergistically in regulating the PS.In this study,we systematically analyze the heading date,PS,and agronomic traits of eight homozygous lines with various combinations of Hd1,Ghd7,and DTH8 alleles in the prr37 background under long-day(LD)and short-day(SD)conditions,respectively.We find that Hd1 alone promotes heading,regardless of the day length.However,under LDs,Hd1 suppresses flowering,in coordination with functional Ghd7 or with Ghd7 and DTH8.These loci cooperate to negatively regulate the Ehd1-Hd3 a/RFT1 pathway and delay heading.Under SDs,Hd1 competes with various heading suppressors to promote heading.Therefore,the dual function of Hd1 is vital for PS.The lines carrying Hd1 alone show reduced plant height with fewer primary and secondary branches in panicles.Lines carrying Ghd7 and DTH8(with hd1)show delayed heading and improve agronomic traits.Overall,our results reveal the regulation of rice PS flowering by the core heading date genes and their effects on agronomic traits,providing valuable information for the selection of rice varieties for adaptation to different light and temperature conditions. | Kangli Sun Minghui Huang Wubei Zong Dongdong Xiao Chen Lei Yanqiu Luo Yingang Song Shengting Li Yu Hao Wanni Luo Bingqun Xu Xiaotong Guo Guangliang Wei Letian Chen Yao-Guang Liu Jingxin Guo | 2022 | Journal of Genetics and Genomics2022,49,5: | 4 |
| 11 | Discovery of Late Carboniferous strata and their tectonic significance in the southern margin of the North China Block(Huoqiu and Gushi areas)显示文摘Late Carboniferous fossils(such as Boultonia? sp., Tabulata, and spiriferoid specimens with smooth shells), bioclastic material(such as crinoid stems and sponge fragments), and Late Ordovician microfossils of the conodont Belodina have been discovered in the lower part of the strata typically referred to as the Neoproterozoic on the boundary of the provinces of Anhui and Henan in the southern margin of the North China Block. These findings prove that the strata contain macrofossils belonging to the Late Carboniferous, which belonged to a carbonate debris flow deposit that was formed under a carbonate slope environment. The conodont fossils might belong to a detrital deposit. Thus, it is possible to reset the stratigraphic sequences and tectonic attributes belonging to the North Huaiyang tectonic belt and limit the Shouxian fault to the boundary between the Dabie Orogen and North China Block. | Shuangying Li Zaifei Ji Song Wang Cheng Cheng Lixiang Guo Dongdong Yang Hao Niu | 2014 | Chinese Science Bulletin2014,59,7: | 3 |

| 13 | Efficient red phosphorescent OLEDs based on the energy transfer from interface exciplex: the critical role of constituting molecules显示文摘A novel acceptor material,9-(4′-(4,6-diphenyl-1,3,5-triazin-2-yl)-[1,1′-biphenyl]-3-yl)-9H-carbazole(o-DTPPC)was developed to form interface exciplex with commonly used donors,to maximize the performances of red phosphorescent organic light emitting diodes(PHOLEDs).It is found that the exciplex involving 4,4′-(cyclohexane-1,1-diyl)bis(N,N-di-p-tolylaniline)(TAPC)exhibits the most significant thermally activated delayed fluorescence(TADF)property,derived from the high triplet energy level as well as strong hole-transporting ability of TAPC.Intriguingly,it is the same donor-acceptor combination which achieved the highest device efficiency when adopted as the host for red PHOLEDs.Maximum efficiencies as high as31.36 cd A^(-1),17.95 lm W^(-1),and 21.01%for the current efficiency,power efficiency and external quantum efficiency,respectively with low efficiency roll-off were realized.The improved performance can be attributed to the efficient TADF properties of the interface exciplex-forming host constituting TAPC,benefiting the F?rster energy transfer.The article first underlines the importance of the constituting molecules in the interface exciplex-forming hosts,shedding new insight about the choice of interface exciplex as the host for PHOLEDs,which may lead to even higher performances,paving their ways towards practical applications. | Xiaozeng Song Dongdong Zhang Tianyu Huang Minghan Cai Lian Duan | 2018 | Science China Chemistry2018,61,7: | 3 |
| 14 | Fixing, preventing, and recovering from concurrency bugs显示文摘Concurrency bugs are becoming widespread with the emerging ubiquity of multicore processors and multithreaded software. They manifest during production runs and lead to severe losses. Many effective concurrency-bug detection tools have been built. However, the dependability of multi-threaded software does not improve until these bugs are handled statically or dynamically. This article discusses our recent progresses on fixing, preventing, and recovering from concurrency bugs. | DENG DongDong JIN GuoLiang de KRUIJF Marc LI Ang LIBLIT Ben LU Shan QI ShanXiang REN JingLei SANKARALINGAM Karthikeyan SONG LinHai WU YongWei ZHANG MingXing ZHANG Wei ZHENG WeiMin | 2015 | Science China(Information Sciences)2015,58,5: | 2 |
| 15 | Sparse channel recovery with inter-carrier interference self-cancellation in OFDM显示文摘A new sparse channel estimation method of orthogonal frequency division multiplexing(OFDM) system based on intercarrier interference(ICI) self-cancellation is investigated. Firstly,based on the characteristic that the ICI generated by a subcarrier to the two adjacent subcarriers is approximately equal, a data pair with opposite sign and equal magnitude is modulated onto two adjacent subcarriers as pilot pair to eliminate the effect of ICI on pilots. Secondly, a new OFDM channel estimation model based on linear time-varying(LTV) model and compressed sensing(CS) is constructed, which obtains the mean of the gains of the multipath.Finally, a pilot pair optimization algorithm based on two layers loop is used to realize the minimization of the mutual coherence of the measurement matrix. For time-varying channel scenes with different numbers or delay of multipath and maximum Doppler frequency shift, the performances of several channel estimation methods are verified by simulation. The result shows that the new method has obvious advantage in both the performance of the channel estimation and the spectral efficiency. | HU Jiansheng SONG Zuxun GUO Shuxia ZHANG Qian SHUI Dongdong | 2018 | Journal of Systems Engineering and Electronics2018,29,4: | 2 |
| 16 | Jigsaw-like mini-pillar platform for multi-mode biosensing显示文摘The multiple sensing provides booming options to eliminate interference and ensure the accuracy of detection by mutually coupling and validating multiple data sets.Here,we integrate the jigsaw-like multifunctional mini-pillar platform to perform multi-mode(electrochemical,fluorescence,surface-enhanced Raman scattering(SERS)and colorimetric)sensing in individual microdroplets.Each mini-pillar connector can parallelize together by specific concave-convex interface to form integrated jigsaw-like platform for multi-mode sensing,and each specific mini-pillar can be modified into the individual sensing unit to read the prescribed signals.We successfully implemented electrochemical,fluorescence,SERS and colorimetric detection by multiple signals coupling to reduce the false positive analysis.Such platform brings a promising clue of in-situ analysis and point-of-care testing for disease diagnosis and health monitoring. | Yongchao Song Dongdong Wang Zehua Li Lirong Wang Chuan Fan Xuecheng He Tailin Xu Xueji Zhang | 2022 | Chinese Chemical Letters2022,33,8: | 1 |
| 17 | Acceleration-Dependent Analysis of Vertical Ball Screw Feed System without Counterweight显示文摘The distinguishing feature of a vertical ball screw feed system without counterweight is that the spindle system weight directly acts on the kinematic joints.Research into the dynamic characteristics under acceleration and deceleration is an important step in improving the structural performance of vertical milling machines.The magnitude and direction of the inertial force change significantly when the spindle system accelerates and decelerates.Therefore,the kinematic joint contact stiffness changes under the action of the inertial force and the spindle system weight.Thus,the system transmission stiffness also varies and affects the dynamics.In this study,a variable-coefficient lumped parameter dynamic model that considers the changes in the spindle system weight and the magnitude and direction of the inertial force is established for a ball screw feed system without counterweight.In addition,a calculation method for the system stiffness is provided.Experiments on a vertical ball screw feed system under acceleration and deceleration with different accelerations are also performed to verify the proposed dynamic model.Finally,the influence of the spindle system position,the rated dynamic load of the screw-nut joint,and the screw tension force on the natural frequency of the vertical ball screw feed system under acceleration and deceleration are studied.The results show that the vertical ball screw feed system has obviously different variable dynamics under acceleration and deceleration.The influence of the rated dynamic load and the spindle system position on the natural frequency under acceleration and deceleration is much greater than that of the screw tension force. | Cunfan Zou Huijie Zhang Jun Zhang Dongdong Song Hui Liu Wanhua Zhao | 2021 | Chinese Journal of Mechanical Engineering2021,34,3: | 1 |
| 18 | Promoting surface reconstruction of NiFe layered double hydroxides via intercalating[Cr(C_(2)O_(4))_(3)]^(3-)for enhanced oxygen evolution显示文摘Rationally manipulating surface reconstruction of catalysts for water oxidation,inducing formation and dynamic accumulation of catalytically active centers still face numerous challenges.Herein,the introduction of[Cr(C_(2)O_(4))_(3)]^(3-)into NiFe LDHs by intercalation engineering to promote surface reconstruction achieves an advanced oxygen evolution reaction(OER)activity.In view of the weak electronegativity of Cr^(3+) in[Cr(C_(2)O_(4))_(3)]^(3-),the intercalation of[Cr(C_(2)O_(4))_(3)]^(3-)is expected to result in an electron-rich structure of Fe sites in NiFe LDHs,and higher valence state of Ni can be formed with the charge transfer between Fe and Ni.The optimized electronic structure of NiFe-[Cr(C_(2)O_(4))_(3)]^(3-)-LDHs with more active Ni^(3+) species and the expedited dynamic generation of Ni^(3+) (Fe)OOH phase during the OER process contributed to its excellent catalytic property,revealed by in situ X-ray absorption spectroscopy,Raman spectroscopy,and quasi-in situ X-ray photoelectron spectroscopy.With the modulated electronic structure of metal sites,NiFe-[Cr(C_(2)O_(4))_(3)]^(3-)-LDHs exhibited promoted OER property with a lower overpotential of 236 mV at the current density of 10 mA cm^(-2).This work illustrates the intercalation of conjugated anion to dynamically construct desired Ni^(3+) sites with the optimal electronic environment for improved OER electrocatalysis. | Yujie Wu Minglei Song Yu-Cheng Huang Chung-Li Dong Yingying Li Yuxuan Lu Bo Zhou Dongdong Wang Jianfeng Jia Shuangyin Wang Yanyong Wang | 2022 | Journal of Energy Chemistry2022,31,11: | 1 |

| 20 | A Unique Ru-N_(4)-P Coordinated Structure Synergistically Waking Up the Nonmetal P Active Site for Hydrogen Production显示文摘Numerous experiments have demonstrated that the metal atom is the active center of monoatomic catalysts for hydrogen evolution reaction(HER),while the active sites of nonmetal doped atoms are often neglected.By combining theoretical prediction and experimental verification,we designed a unique ternary Ru-N_(4)-P coordination structure constructed by monodispersed Ru atoms supported on N,P dual-doped graphene for highly efficient hydrogen evolution in acid solution.The density functional theory calculations indicate that the charge polarization will lead to the most charge accumulation at P atoms,which results in a distinct nonmetallic P active sites with the moderate H∗adsorption energy.Notably,these P atoms mainly supply highly efficient catalytic sites with ultrasmall absorption energy of 0.007 eV.Correspondingly,the Ru-N_(4)-P demonstrated outstanding HER performance not only in an acidic condition but also in alkaline environment.Notably,the performance of Ru-NPC catalyst at high current is even superior to the commercial Pt/C catalysts,whether in acidic or alkaline medium.Our in situ synchrotron radiation infrared spectra demonstrate that a P-H_(ads) intermediate is continually emerging on the Ru-NPC catalyst,actively proving the nonmetallic P catalytically active site in HER that is very different with previously reported metallic sites. | Chuanqiang Wu Shiqing Ding Daobin Liu Dongdong Li Shuangming Chen Huijuan Wang Zeming Qi Binghui Ge Li Song | 2020 | Research2020,,1: | 1 |
