| 1 | TOWARD COLLECTIVE INTELLIGENCE OF ONLINE COMMUNITIES:A PRIMITIVE CONCEPTUAL MODEL显示文摘Inspired by the ideas of Swarm Intelligence and the'global brain',a concept of'community intelligence'is suggested in the present paper,reflecting that some'intelligent'features may emerge in a Web-mediated online community from interactions and knowledge-transmissions between the commumty members.This possible research field of community intelligence is then examined under the backgrounds of'community'and'intelligence'researches.Furthermore,a conceptual model of community intelligence is developed from two views.From the structural view,the community intelligent system is modeled as a knowledge supernetwork that is comprised of triple interwoven networks of the media network,the human network,and the knowledge network.Furthermore,based on a dyad of knowledge in two forms of'knowing'and'knoware',the dynamic view describes the basic mechanics of the formation and evolution of'community intelligence'.A few relevant research issues are shortly discussed on the basis of the proposed conceptual model. | Shuangling LUO Haoxiang XIA Taketoshi YOSHIDA Zhongtuo WANG | 2009 | Journal of Systems Science and Systems Engineering2009，18，2： | 10 |
| 2 | New Re-Os Isotopic Constrains on the Formation of the Metalliferous Deposits of the Lower Cambrian Niutitang Formation显示文摘The Terreneuvian Epoch(541–521 Ma)is also an important period for metallogenesis in South China, as was represented by the widespread occurrences of Ni-Mo polymetallic layers on the antecedent shallow platform margin and the V-enriched black shales in deeper slope-basin settings. In this study, we have measured Re-Os isochron ages of Ni-Mo polymetallic layers(Songlin, Niuchang, Sancha, Chuanpengwan), V-rich black shales(Bahuang), and non-metalliferous black shales(Shuidong) in the basal Niutitang Formation in Guizhou and Hunan province, South China. The Ni-Mo polymetallic layers and V-enriched black shales have similar Re-Os isochron ages, suggesting concurrent deposition of these two types of metalliferous ores. This suggestion is consistent with the traditional stratigraphic correlation by using the nodular phosphorite bed directly underlying these metalliferous layers as a stratigraphic marker. Furthermore, the metalliferous ores and non-metalliferous black shales have similar initial ^(187)Os/^(188) Os ratios of 0.8–0.9, arguing for a dominant seawater origin with minor contribution of hydrothermal activity. Furthermore, Re-Os isotopic data also imply that Ni-Mo and V ore might have derived from the same source. We suggest that the spatial distribution of metalliferous ores can be explained by the development of non-sulfidic anoxic-suboxic wedge(NSASW) in the slope-basin and sulfidic wedge in the previous platform margin. Upwelling of deep water first transects the mildly reduced, organic rich NSASW, in which V(V) is reduced to V(IV), and is preferentially removed from seawater by organometallic complex formation. As a result, V-rich black shale deposits in the slope-basin of Yangtze Platform. Further movement of deep water into the sulfidic platform margin results in Ni-Mo polymetallic layer formation. | Yong Fu Lin Dong Chao Li Wenjun Qu Haoxiang Pei Wenlang Qiao Bing Shen | 2016 | Journal of Earth Science2016，27，2： | 9 |
| 3 | Experimental Study on Interaction Between Degrees of Freedom in a Wave Buoy显示文摘Increasing degrees of freedom(DOFs)is a useful way to raise the power capture efficiency of oscillating wave energy converters.Thus,this study proposes a buoy with three DOFs,which are surge,heave,and pitch.The hydrodynamic performance and power capture efficiency of the buoy is physically modeled.Amplitudes of unidirectional and coupled motions are compared to analyze the interaction effect between freedoms under conditions with and without power take-off damping.The capture width ratio and corresponding growth rates are also calculated.Results show that the buoy makes a periodic sinusoidal(or approximate)movement in every DOF.Coupling effect can cause an increase in the amplitude in one DOF and a decrease in the amplitudes of the others.This phenomenon shows that the kinematic energy of the buoy redistributes to all DOFs compared with the unidirectional conditions.Adding DOFs can improve the power absorption of the buoy in most cases,but the number of DOFs is not the more the better. | HUANG Shuting SHI Hongda CAO Feifei TAN Junzhe CHENG Haixun LI Demin LIU Shangze GONG Haoxiang TAO Ji | 2019 | Journal of Ocean University of China2019，18，6： | 5 |
| 4 | Experimental investigation of a hypersonic I-shaped configuration with a waverider compression surface显示文摘Lift-to-drag ratio (L/D) is nearly the most important index in determining the aerodynamic performance of a hypersonic flight vehicle,because the flight distance is linearly proportional to the L/D according to Breguet's equation.In general,the higher the L/D of a vehicle,the greater the flight range if the specific impulse,structural mass ratio,and flight velocity are given.Naturally,the pursuit of a high L/D for hypersonic vehicles has never ceased [1,2]. | GuangLi Li Kai Cui YingZhou Xu HaoXiang Wang Jing Yang XianGui Xu | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，5： | 5 |
| 5 | Prussian Blue Analogues in Aqueous Batteries and Desalination Batteries显示文摘In the applications of large-scale energy storage,aqueous batteries are considered as rivals for organic batteries due to their environmentally friendly and low-cost nature.However,carrier ions always exhibit huge hydrated radius in aqueous electrolyte,which brings difficulty to find suitable host materials that can achieve highly reversible insertion and extraction of cations.Owing to open threedimensional rigid framework and facile synthesis,Prussian blue analogues(PBAs)receive the most extensive attention among various host candidates in aqueous system.Herein,a comprehensive review on recent progresses of PBAs in aqueous batteries is presented.Based on the application in different aqueous systems,the relationship between electrochemical behaviors(redox potential,capacity,cycling stability and rate performance)and structural characteristics(preparation method,structure type,particle size,morphology,crystallinity,defect,metal atom in highspin state and chemical composition)is analyzed and summarized thoroughly.It can be concluded that the required type of PBAs is different for various carrier ions.In particular,the desalination batteries worked with the same mechanism as aqueous batteries are also discussed in detail to introduce the application of PBAs in aqueous systems comprehensively.This report can help the readers to understand the relationship between physical/chemical characteristics and electrochemical properties for PBAs and find a way to fabricate high-performance PBAs in aqueous batteries and desalination batteries. | Chiwei Xu Zhengwei Yang Xikun Zhang Maoting Xia Huihui Yan Jing Li Haoxiang Yu Liyuan Zhang Jie Shu | 2021 | Nano-Micro Letters2021，13，11： | 4 |
| 6 | Concentration of circulating microparticles:a new biomarker of acute heart failure after cardiac surgery with cardiopulmonary bypass显示文摘Acute heart failure(AHF)is a severe complication after cardiac surgery with cardiopulmonary bypass(CPB).Although some AHF biomarkers have been used in clinic,they have limitations when applied in the prediction and diagnosis of AHF after cardiac surgery with CPB,and there are still no effective and specific biomarkers.We and other researchers have shown that circulating microparticles(MPs)increased in a variety of cardiovascular diseases.However,whether the concentration of circulating MPs could be a new biomarker for AHF after cardiac surgery remains unknown.Here,90 patients undergoing cardiac surgery with CPB and 45 healthy subjects were enrolled.Patients were assigned into AHF(n=14)or non-AHF(n=76)group according to the diagnosis criteria of AHF.The concentrations of circulating MPs were determined before,as well as 12 h and 3 days after operation with nanoparticle tracking analysis technique.MPs concentrations in patients before surgery were significantly higher than those of healthy subjects.Plasma levels of MPs were significantly elevated at 12 h after surgery in patients with AHF,but not in those without AHF,and the circulating MPs concentrations at 12 h after surgery were higher in AHF group compared with non-AHF group.Logistic regression analysis indicated that MPs concentration at postoperative 12 h was an independent risk factor for AHF.The area under receiver operating characteristic curve for MPs concentration at postoperative 12 h was 0.87 and the best cut-off value is 5.20×10~8 particles mL~(–1)with a sensitivity of 93%and a specificity of 70%.These data suggested that the concentration of circulating MPs might be a new biomarker for the occurrence of AHF after cardiac surgery with CPB. | Yuquan Li Haoxiang Yuan Caiyun Chen Chao Chen Jian Ma Yating Chen Yan Li Yupeng Jian Donghong Liu Zhijun Ou Jingsong Ou | 2021 | Science China(Life Sciences)2021，64，1： | 3 |

| 8 | Research on mode localization of reticulated shell structures显示文摘Reticulated shell structures (RSSs) are characterized as cyclically periodic structures. Mistuning of RSSs will induce structural mode localization. Mode localization has the following two features: some modal vectors of the structure change remarkably when the values of its physical parameters (mass or stiffness) have a slight change; and the vibration of some modes is mainly restricted in some local areas of the structure. In this paper, two quantitative assessment indexes are introduced that correspond to these two features. The first feature is studied through a numerical example of a RSS, and its induced causes are analyzed by using the perturbation theory. The analysis showed that internally, mode localization is closely related to structural frequencies and externally, slight changes of the physical parameters of the structure cause instability to the RSS. A scaled model experiment to examine mode localization was carried out on a Kiewit single-layer spherical RSS, and both features of mode localization are studied. Eight tests that measured the changes of the physical parameters were carried out in the experiment. Since many modes make their contribution in structural dynamic response, six strong vibration modes were tested at random in the experimental analysis. The change and localization of the six modes are analyzed for each test. The results show that slight changes to the physical parameters are likely to induce remarkable changes and localization of some modal vectors in the RSSs. | Yan Weiming Wang Zhuo He Haoxiang | 2011 | Earthquake Engineering and Engineering Vibration2011，10，1： | 3 |
| 9 | Cu3(PO4)2: Novel Anion Convertor for Aqueous Dual‑Ion Battery显示文摘Electrode materials which can reversibly react with anions are of interest for aqueous dual-ion batteries.Herein,we propose a novel anion electrode,Cu3(PO4)2,for constructing an aqueous dual-ion cell.The Cu3(PO4)2 electrode can operate in a quasi-neutral condition and deliver a reversible capacity of 115.6 mAh g^−1 with a well-defined plateau at−0.17 V versus Ag/AgCl.Its reaction mechanism shows that Cu3(PO4)2 decomposes into Cu2O and subsequently is converted into Cu during the initial discharge process.In the following charge process,Cu is oxidized into Cu2O.It suggests Cu3(PO4)2 reacts with OH−ions instead of PO43−ions after the initial discharge process and its potential thereby depends upon the OH−ions concentration in electrolyte.Additionally,an aqueous dual-ion cell is built by using pretreated Cu3(PO4)2 and Na0.44MnO2 as anode and cathode,respectively.During cycling,OH−ions and Na^+ions in electrolyte can be stored and released.Such a cell can provide a discharge capacity of 52.6 mAh g^−1 with plateaus at 0.70 and 0.45 V,exhibiting the potential of application.This work presents an available aqueous dual-ion cell and provides new insights into renewable energy storage and adjustment of the OH−ions concentration in aqueous buffer solution. | Haoxiang Yu Chenchen Deng Huihui Yan Maoting Xia Xikun Zhang Zhen‑Bo Wang Jie Shu | 2021 | Nano-Micro Letters2021，13，3： | 3 |
| 10 | Hydrogen Bond-Assisted Ultra-Stable and Fast Aqueous NH_(4)^(+)Storage显示文摘Aqueous ammonium ion batteries are regarded as eco-friendly and sustainable energy storage systems.And applicable host for NH_(4)^(+)in aqueous solution is always in the process of development.On the basis of density functional theory calcula-tions,the excellent performance of NH_(4)^(+)insertion in Prussian blue analogues(PBAs)is proposed,especially for copper hexacyanoferrate(CuHCF).In this work,we prove the outstanding cycling and rate performance of CuHCF via electrochemical analyses,delivering no capacity fading during ultra-long cycles of 3000 times and high capacity retention of 93.6%at 50 C.One of main contributions to superior performance from highly reversible redox reaction and structural change is verified during the ammoniation/de-ammoniation progresses.More importantly,we propose the NH_(4)^(+)diffusion mechanism in CuHCF based on con-tinuous formation and fracture of hydrogen bonds from a joint theoretical and experimental study,which is another essential reason for rapid charge transfer and superior NH_(4)^(+)storage.Lastly,a full cell by coupling CuHCF cathode and polyaniline anode is constructed to explore the practical application of CuHCF.In brief,the outstanding aqueous NH_(4)^(+)storage in cubic PBAs creates a blueprint for fast and sustainable energy storage. | Xikun Zhang Maoting Xia Haoxiang Yu Junwei Zhang Zhengwei Yang Liyuan Zhang Jie Shu | 2021 | Nano-Micro Letters2021，13，9： | 2 |
| 11 | A New Type of Rare Metal Deposit:The Yushishan Leptynite-Type Nb-Ta Deposit in Eastern Altun,Gansu Province,NW China显示文摘The Yusishan deposit is a newly found leptynite-type niobium and tantalum(Nb-Ta)deposit,which is located in the Eastern Altun of Gansu Province.The leptynite of the Neoproterozoic Aoyougou Formation occurs more than 10 km long and 3 km wide.In this paper,we carried out a detailed study of the leptynite and related mineralization.The U-Pb dating of zircon reveals ages of 831±5 Ma and 790±5 Ma for the unmineralized leptynite and 491±4 Ma and 455±4 Ma for the mineralized leptynite.The petrographic and geochemical evidence identified the protolith of the leptynite as alkalin e volcanic rocks that erupted during Neoproterozoic at ca.830 Ma.At ca.490 Ma,the tectono-magmatic and metamorphic event triggered remobilization and enrichment of Nb-Ta as well as other critical metals(REE,Zr,Hf etc)with the formation of industry orebodies in the leptynite strata.The Yushishan deposit presents many similarities with the alkaline volcanic rocks related rare metal deposits in the south Qinling of China and the Brochman,Toogni and Southern Peak Range deposits in Australian.We therefore propose that the Yushishan deposit is a new type(sub-type)of Nb-Ta deposit and termed as leptynite type that represents the metamorphic counterpart of the alkaline volcanic rocks related rare metal deposits. | JIANG SHAOYONG LIU TAO ZHANG HAOXIANG CAO SHUYUN ZHENG RUOHONG LI TONGGUO YU JUNPENG WU YIBU | 2022 | Acta Geologica Sinica(English Edition)2022，96，5： | 2 |
| 12 | Characterization of viromes within mosquito species in China显示文摘Mosquitoes are vectors of multiple disease-causing agents that cause worldwide outbreaks of serious infectious diseases in both humans and animals. These arboviral agents include Dengue virus (DENV), Zika virus (ZIKV), chikungunya virus, yellow fever virus, Japanese encephalitis virus (JEV),and Rift Valley fever virus. Thus, mosquitoes are key to the study of viral origin, spread, and the epidemic tendency of these infectious diseases (Hall and Macdonald, 2016). | Jiang Du Fan Li Yelin Han Shihong Fu Bo Liu Nan Shao Haoxiang Su Weijia Zhang Dandan Zheng Wenwen Lei Jie Dong Lilian Sun Ying He Jianmin Wang Fan Yang Huanyu Wang Guodong Liang Zhiqiang Wu Qi Jin | 2020 | Science China(Life Sciences)2020，63，7： | 2 |
| 13 | Precise Background Noise Power Estimate for Echo Cancellation显示文摘The reconstruction of background noise from an error signal of an adaptive filter is a key issue for developing Variable Step-Size Normalized Least Mean Square (VSS-NLMS) algorithm in the context of Echo Cancellation (EC). The core parameter in this algorithm is the Background Noise Power (BNP); in the estimation of BNP, the power difference between the desired signal and the filter output, statistically equaling to the error signal power, has been widely used in a rough manner. In this study, a precise BNP estimate is implemented by multiplying the rough estimate with a corrective factor, taking into consideration the fact that the error signal consists of background noise and misalignment noise. This corrective factor is obtained by subtracting half of the latest VSS value from 1 after analyzing the ratio of BNP to the misalignment noise. Based on the precise BNP estimate, the PVSS-NLMS algorithm suitable for the EC system is eventually proposed. In practice, the proposed algorithm exhibits a significant advantage of easier controllability application, as prior knowledge of the EC environment can be neglected. The simulation results support the preciseness of the BNP estimation and the effectiveness of the proposed algorithm. | Wen Haoxiang Lai Xiaohan Chen Longdao | 2012 | China Communications2012，9，11： | 2 |
| 14 | Phylogenetic Analysis of the Dengue Virus Strains Causing the 2019 Dengue Fever Outbreak in Hainan,China显示文摘Dengue virus is an arthropod-borne pathogen that is transmitted to humans primarily by Aedes spp.mosquitos,causing the acute infectious disease,dengue fever(DF).Until 2019,no dengue outbreak had been reported in Hainan Province for over 20 years.However,in early September of 2019,an increasing number of infected cases appeared and the DF outbreak lasted for over one month in Haikou City,Hainan Province.In our study,we collected 97 plasma samples from DF patients at three hospitals,as well as 1585 mosquito larvae samples from puddles in different areas of Haikou.There were 49(50.5%)plasma samples found to be strongly positive and 9(9.3%)plasma samples were weakly positive against the NS1 antigen.We discovered DENV both in the patient's plasma samples and mosquito larvae samples,and isolated the virus from C6/36 cells inoculated with the acute phase serum of patients.Phylogenetic analysis revealed that the new strains were the most closely related to the epidemic strain in the southern regions of China,belonging to lineageⅣ,genotypeⅠ,DENV-1.Compared to the seven closest strains from neighboring countries and provinces,a total of 18 amino acid mutations occurred in the coding sequences(CDS)of the new isolated strain,DENV1 HMU-HKU-2.Our data shows that dengue virus is re-emerged in Hainan,and pose new threats for public health.Thus regular molecular epidemiological surveillance is necessary for control and prevention of DENV transmission. | Jiang Du Liyuan Zhang Xiaoyuan Hu Ruoyan Peng Gaoyu Wang Yi Huang Wenqi Wang Kunliang Wu Qiang Wang Haoxiang Su Fan Yang Yun Zhang Chuanning Tang Xiuji Cui Lina Niu Gang Lu Meifang Xiao Yongguo Du Feifei Yin | 2021 | Virologica Sinica2021，36，4： | 2 |
| 15 | Environment-friendly surface cleaning using micro-nano bubbles显示文摘Cleaning a surface using a solution containing a large number of micro to nano scale bubbles has significant advantage regarding environmental protection.This review first briefly introduces the cleaning mechanism of micro-nano bubbles(MNBs),including physical and chemical effects.Then the applications of MNBs in cleaning of metal parts,precision parts,cultural relics or food are introduced.After that,coupled cleaning method of ultrasound and bubbles is introduced.Finally,the characterization methods for the cleaning effect are introduced,which mainly focuses on the changes of physico-chemical properties(mass or cleaning area,infiltration,colony number and light scattering intensity)of the cleaned parts or that(like conductivity)of the solvent.It is believed that MNBs technology will be applied in a broader range of surface cleaning applications. | Nuo Jin Fenghua Zhang Yan Cui Le Sun Haoxiang Gao Ziang Pu Weimin Yang | 2022 | Particuology2022，20，7： | 2 |
| 16 | A MODIFIED ANT-BASED TEXT CLUSTERING ALGORITHM WITH SEMANTIC SIMILARITY MEASURE显示文摘Ant-based text clustering is a promising technique that has attracted great research attention. This paper attempts to improve the standard ant-based text-clustering algorithm in two dimensions. On one hand, the ontology-based semantic similarity measure is used in conjunction with the traditional vector-space-model-based measure to provide more accurate assessment of the similarity between documents. On the other, the ant behavior model is modified to pursue better algorithmic performance. Especially, the ant movement rule is adjusted so as to direct a laden ant toward a dense area of the same type of items as the ant’s carrying item, and to direct an unladen ant toward an area that contains an item dissimilar with the surrounding items within its Moore neighborhood. Using WordNet as the base ontology for assessing the semantic similarity between documents, the proposed algorithm is tested with a sample set of documents excerpted from the Reuters-21578 corpus and the experiment results partly indicate that the proposed algorithm perform better than the standard ant-based text-clustering algorithm and the k-means algorithm. | Haoxiang XIA Shuguang WANG Taketoshi YOSHIDA | 2006 | Journal of Systems Science and Systems Engineering2006，15，4： | 2 |
| 17 | Onset of instability of a flag in uniform flow显示文摘This paper numerically and analytically studies the onset of instability of a flag in uniform flow.The three-dimensional(3D) simulation is performed by using an immersed-boundary method coupled with a nonlinear finite element method.The global stability,bistability and instability are identified in the 3D simulations.The Squire's theorem is extended to analyze the stability of the fluid-flag system with 3D initial perturbations.It is found that if a parallel flow around the flag admits an unstable 3D disturbance for a certain value of the flutter speed,then a two-dimensional(2D) disturbance at a lower flutter speed is also admitted.In addition,the growth rate of 2D disturbance is larger than that of the 3D disturbance. | Fangbao Tian Xiyun Lu Haoxiang Luo | 2012 | Theoretical & Applied Mechanics Letters2012，2，2： | 2 |

| 20 | Multi-stage Defender-Attacker-Defender Model for Distribution System Resilience Enhancement in Ice Storms with Line Hardening,Mobile Device and Repair Crew Dispatching显示文摘This paper proposes a co-optimal strategy using line hardening,mobile devices(mobile ice-melting device,mobile emergency generator,mobile energy storage system),and repair crew dispatching to improve distribution system resilience during ice storms.A multi-stage defender-attacker-defender model is established to take into account interactions and coupling relationships between different measures.In our proposed model,ice storms will attack the distribution and transportation system in a worst-case scenario,affecting system performance from various perspectives.Corresponding to the different operating states in the distribution system affected by ice storms,aiming at minimizing the weighted load shedding value,this paper applies various measures to different stages to improve the response and defense capabilities to ice storms and realize restoration of the distribution system ultimately.The nested column-and-constraint generation algorithm is used to solve the model efficiently.The effectiveness of the proposed model and solution method for enhancing the distribution system resilience is verified on the modified IEEE 33-bus distribution system and modified realworld zone of Caracas 141-bus distribution system. | Ran Tao Dongmei Zhao Haoxiang Wang Xuan Xia | 2023 | CSEE Journal of Power and Energy Systems2023，9，3： | 1 |
