| 1 | Fast increasing of surface ozone concentrations in Pearl River Delta characterized by a regional air quality monitoring network during 2006–2011显示文摘Based on the observation by a Regional Air Quality Monitoring Network including 16 monitoring stations, temporal and spatial variations of ozone(O3), NO2and total oxidant(Ox) were analyzed by both linear regression and cluster analysis. A fast increase of regional O3concentrations of 0.86 ppbV/yr was found for the annual averaged values from 2006 to 2011 in Guangdong, China. Such fast O3increase is accompanied by a correspondingly fast NOx reduction as indicated by a fast NO2 reduction rate of 0.61 ppbV/yr. Based on a cluster analysis, the monitoring stations were classified into two major categories – rural stations(non-urban) and suburban/urban stations. The O3concentrations at rural stations were relatively conserved while those at suburban/urban stations showed a fast increase rate of 2.0 ppbV/yr accompanied by a NO2 reduction rate of 1.2 ppbV/yr. Moreover, a rapid increase of the averaged O3 concentrations in springtime(13%/yr referred to 2006 level) was observed, which may result from the increase of solar duration, reduction of precipitation in Guangdong and transport from Eastern Central China. Application of smog production algorithm showed that the photochemical O3production is mainly volatile organic compounds(VOC)-controlled. However, the photochemical O3production is sensitive to both NOx and VOC for O3pollution episode. Accordingly, it is expected that a combined NOx and VOC reduction will be helpful for the reduction of the O3 pollution episodes in Pearl River Delta while stringent VOC emission control is in general required for the regional O3 pollution control. | Jinfeng Li Keding Lu Wei Lv Jun Li Liuju Zhong Yubo Ou Duohong Chen Xin Huang Yuanhang Zhang | 2014 | Journal of Environmental Sciences2014，26，1： | 51 |

| 3 | Experimental long-distance quantum secure direct communication显示文摘Quantum secure direct communication(QSDC) is an important quantum communication branch, which realizes the secure information transmission directly without encryption and decryption processes.Recently, two table-top experiments have demonstrated the principle of QSDC. Here, we report the first long-distance QSDC experiment, including the security test, information encoding, fiber transmission and decoding. After the fiber transmission of 0.5 km, quantum state fidelities of the two polarization entangled Bell states are 91% and 88%, respectively, which are used for information coding. We theoretically analyze the performance of the QSDC system based on current optical communication technologies,showing that QSDC over fiber links of several tens kilometers could be expected. It demonstrates the potential of long-distance QSDC and supports its future applications on quantum communication networks. | Feng Zhu Wei Zhang Yubo Sheng Yidong Huang | 2017 | Science Bulletin2017，62，22： | 25 |
| 4 | Safety Research in Traditional Chinese Medicine: Methods, Applications, and Outlook显示文摘Traditional Chinese medicine (TCM) is a medical system that has collected and summarized abundant clinical experience over its long history of more than 2000 years. However, the frequent occurrence of TCM-induced adverse reactions has hindered the modernization and internationalization of TCM, while attracting increasing attention from around the world. Unlike chemical drugs and biological agents, the difficulties involved in research on the toxicity and safety of TCM mainly include the complexity of its components and the unpredictability of drug–body interactions. Much of TCM, which has overall therapeutic effects, has the typical mechanisms of multiple components, multiple pathways, and multiple targets. While considering the gradualness and unpredictability of TCM toxicity, the ambiguity of toxicants and safe dosage, and individual differences during long-term TCM administration, we have systematically established key techniques for the toxicity assessment of TCM. These techniques mainly include TCM toxicity discovery in an early phase, based on a combination of drug toxicology genomics and metabolomics;methods to identify dose–toxicity relationships in TCM;and integrated techniques for the exploration of TCM interactions, such as fast-screening tests based on drug-metabolizing enzymes and receptor pathways. In particular, we have developed a new technical system for TCM safety evaluation using molecular toxicology, which has been validated well in research on TCM compatibility contraindication, quality control, and allergen discovery. The application of this key technical platform is introduced here in detail. This application includes model organisms, toxicant biomarkers, a magnetic suspension technique, and the application of network toxicology and computational toxicology in research on the toxicity of Fructus toosendan, Semen cassiae, Polygonum multiflorum, and Fructus psoraleae. | Yue Gao Aihua Liang Xiaohui Fan Limin Hu Feiran Hao Yubo Li | 2019 | Engineering2019，5，1： | 19 |
| 5 | Dynamics of Saline-alkali Land and Its Ecological Regionalization in Western Songnen Plain, China显示文摘As the important reserve land resources for food production,saline-alkali land should play a significant role to ensure the national food security in the context of global food crisis. The western Songnen Plain is one of main distribution regions of saline-alkali land in China,with great potential in agricultural development. In this study,the extent,transformation,spatial distribution and temporal change of saline-alkali land in the western Songnen Plain during 1954–2005 were investigated by using remote sensing and GIS spatial analysis methods. Saline-alkali land change was detected from a temporal series of topographic maps in 1954,satellite images of Landsat MSS in 1976,Landsat TM/ETM in 1988,2000 and 2005 through artificial visual interpretation. The results indicated a significant expansion in saline-alkali land area and aggravation in salinization. The area of saline-alkali land had increased from 401.48×103 ha in 1954 to 1 097.45×103 ha in 2005. While the ratio of light,moderate and serious salinized land areas changed from 6.72︰2.92︰1.00 to 1.25︰1.06︰1.00 in the study period. Grassland,cropland,swampland and water body were the major land use and land cover types from which saline-alkali land transformed. And the secondary salinization occured mainly in Da′an City,Tongyu County,Changling County,Daqing City,Dorbod Mongolian Autonomous County and Zhaoyuan County. Finally,seven large ecoregions and 14 corresponding sub-ecoregions were delineated out based on spatio-temopral dynamic characteristics of saline-alkali land and geo-relational environmental attributes. According to the results,measures of amelioration and ways of development of saline-alkali land in the western Songnen Plain were put forward. | YANG Jiuchun ZHANG Shuwen LI Ying BU Kun ZHANG Yubo CHANG Liping ZHANG Yangzhen | 2010 | Chinese Geographical Science2010，20，2： | 17 |

| 7 | A survey of executive compensation contracts in China's listed companies显示文摘We analyze 228 executive compensation contracts voluntarily disclosed by Chinese listed firms and find that central-government-controlled companies disclose more information in executive compensation contracts than localgovernment-controlled and non-government-controlled companies. Cashbased payments are the main form of executive compensation, whereas equity-based payments are seldom used by Chinese listed companies. On average, there are no significant differences in the value of basic salaries and performance-based compensation in executive compensation contracts.But, compared with their counterparts in non-government-controlled companies, executives in government-controlled companies are given more incentive compensation. Accounting earnings are typically used in executive compensation contracts, with few firms using stock returns to evaluate their executives. However, the use of non-financial measures has increased significantly since 2007. | Yubo Lia Fang Lou Jiwei Wang Hongqi Yuan | 2013 | China Journal of Accounting Research2013，，3： | 15 |
| 8 | Effect of microporosity on scaffolds for bone tissue engineering显示文摘Microporosity has a critical role in improving the osteogenesis of scaffolds for bone tissue engineering.Although the exact mechanism,by which it promotes new bone formation,is not well recognized yet,the related hypothesis can be found in many previous studies.This review presents those possible mechanisms about how the microporosity enhances the osteogenic-related functions of cells in vitro and the osteogenic activity of scaffolds in vivo.In summary,the increased specific surface areas by microporosity can offer more protein adsorption sites and accelerate the release of degradation products,which facilitate the interactions between scaffolds and cells.Meanwhile,the unique surface properties of microporous scaffolds have a considerable effect on the protein adsorption.Moreover,capillary force generated by the microporosity can improve the attachment of bone-related cells on the scaffolds surface,and even make the cells achieve penetration into the micropores smaller than them.This review also pays attention to the relationship between the biological and mechanical properties of microporous scaffolds.Although lots of achievements have been obtained,there is still a lot of work to do,some of which has been proposed in the conclusions and perspectives part. | Ke Zhang Yubo Fan Nicholas Dunne Xiaoming Li | 2018 | Regenerative Biomaterials2018，5，2： | 15 |
| 9 | Response of grain yield to plant density and nitrogen rate in spring maize hybrids released from 1970 to 2010 in Northeast China显示文摘The objective of this study was to identify the response of grain yield to plant density and nitrogen rate in spring maize hybrids released from 1970 to 2010 and grown extensively in Northeast China.Twenty-one hybrids were grown for 2 years in Northeast China at densities of 30,000,52,500,75,000,and 97,500 plants ha^(-1)and N application levels of 0,150,300,and 450 kg N ha^(-1).Irrespective of density or nitrogen application rate,grain yields both per plant and per unit area were significantly higher for newer than older hybrids.As plant density increased from 30,000 to 97,500 plant ha^(-1),yield per plant of 1970 s,1980 s,1990 s,and 2000 s hybrids decreased by 50%,45%,46%,and 52%,respectively.The response of grain yield per unit area to plant density was curvilinear.The estimated optimum plant densities were about 58,000,49,000,65,000,and 65,000 plants ha^(-1)for hybrids released in the 1970 s,1980s,1990 s,and 2000 s,respectively.The theoretical optimum densities for the hybrids released from the 1970 s to the 2000 s increased by 1750 plants ha^(-1)decade^(-1).Nitrogen fertilization significantly increased grain yields per plant and per unit area for all hybrids.The theoretical optimum N application rates for high yield for hybrids released in the 1970 s and 1980 s were about 280 and 360 kg ha^(-1),and the hybrids from the 1990 s and 2000 s showed highest yield at 330 kg ha^(-1)N.No significant difference in the grain yields of 2000 s hybrids between the N levels of 150 to 450 kg ha^(-1)was found.Significant yield gains per plant and per unit area were found,with average increases of 17.9 g plant^(-1)decade^(-1)and936 kg ha^(-1)decade^(-1)over the period 1970–2010,respectively.Yield gains were attributed mainly to increased yield per plant,contributed by increases in kernel number per ear and1000-kernel weight.The rates of lodging and barren plants of newer hybrids were significantly lower than those of older ones,especially at high plant density. | Chunrong Qian Yang Yu Xiujie Gong Yubo Jiang Yang Zhao Zhongliang Yang Yubo Hao Liang Li Zhenwei Song Weijian Zhang | 2016 | The Crop Journal2016，4，6： | 15 |

| 11 | Passive source range estimation with a single receiver in shallow water显示文摘An approach for long-range passive impulsive source ranging with a single receiver in shallow water is proposed,which utilizes the frequency spectrum of the warped signal autocorrelation function via warping transform.For an ideal waveguide,there are invariable frequency features both in the frequency spectrum of the warped signal corresponding to modal cut-off frequencies and the warped signal autocorrelation function due to modal interference.These intrinsic frequency features can be used to passive source ranging.So,the approximate relationship between the frequency of warped signal at an unknown source range and the intrinsic frequency extracted by the time warping transform is derived.These rules can be generalized to an actual shallow water waveguide.Employing an acoustic model to offer the invariable frequency spectrum features,the impulsive signal data collected by a single hydrophone in the North Yellow Sea in December 2011 are analyzed to verify the proposed source ranging approach.The estimated ranges are in good agreement with the ranges measured by GPS,and the mean relative error of range estimation is less than 10%. | QI Yubo ZHOU Shihong REN Yun WANG Dejun LIU Jianjun FENG Xiqiang | 2015 | Chinese Journal of Acoustics2015，34，1： | 13 |

| 13 | Effect of ultrasonic treatment and Sr addition on microstructure of Al-20%Si alloy显示文摘Many investigations have revealed that transition of melt structure can effectively infl uence the fi nal solidifi cation microstructures.In this study,ultrasonic treatment was applied to Al-20%Si melt and Sr-modif ied Al-20%Si melt at 720℃(i.e.above liquidus of about 690℃)for 60 s,and then the melt was quickly quenched to room temperature.Experimental results show that ultrasonic treatment can ref ine the primary Si phase andα-Al of Al-20%Si alloy;strontium can make the morphology of Si phase spheroidized and refi ned as Sr addition changes the faceted growth characteristic of Si phase;however,the ref inement effect of ultrasonic treatment on the primary Si phase andα-Al is weakened by Sr addition. | Miao Long Lu Yiping Zhang Yubo Fu Ying Li Tingju | 2013 | China Foundry2013，10，4： | 10 |
| 14 | Multipartite entanglement concentration for nitrogen-vacancy center and microtoroidal resonator system显示文摘We describe a high efcient entanglement concentration protocol(ECP)for multi-particle less-entangled nitrogen-vacancy(N-V)center and microtoroidal resonator system.In the ECP,we only require one pair of less-entangled state,two auxiliary N-V center in microcavities and some single photons.After the photon passing through the microcavity,by measuring the polarization of the photon,a maximally entangled W state can be obtained with some success probability.This ECP does not need to destroy the solid qubit,which makes it more feasible.Moreover,by resorting to more single photons,it can be repeated to reach a high success probability.These features make this ECP useful in current long-distance quantum communications. | SHENG YuBo LIU Jiong ZHAO ShengYang ZHOU Lan | 2013 | Chinese Science Bulletin2013，58，28： | 10 |
| 15 | A Trusted Attestation Mechanism for the Sensing Nodes of Internet of Things Based on Dynamic Trusted Measurement显示文摘Internet of things has been widely applied to industrial control, smart city and environmental protection, in these application scenarios, sensing node needs to make real-time response to the feedback control of the application layer. Therefore, it is necessary to monitor whether or not awareness nodes are trusted in real time, but the existing mechanisms for trusted certification lack the real-time measurement and tracking of the sensing node. To solve the above problems,this paper proposes a dynamic metric based authentication mechanism for sensing nodes of Internet of things. Firstly, the dynamic trustworthiness measure of the sensing nodes is carried out by introducing the computational function such as the trust function, the trustworthiness risk assessment function, the feedback control function and the active function of the sensing node. The dynamic trustworthiness measure of sensing nodes from multiple dimensions can effectively describe the change of trusted value of sensing nodes. Then, on the basis of this, a trusted attestation based on node trusted measure is realized by using the revocable group signature mechanism of local verifier. The mechanism has anonymity, unforgeability and traceability, which is proved the security in the standard model. Simulationexperiments show that the proposed trusted attestation mechanism is flexible, practical and efficient and has better attack resistance. It can effectively guarantee the reliable data transmission of nodes and realize the dynamic tracking of node reliability, which has a lower impact on system performance. | Bei Gong Yubo Wang Xiangang Liu Fazhi Qi Zhihui Sun | 2018 | China Communications2018，15，2： | 10 |
| 16 | Comparative study of the mechanical properties,micro-structure,and composition of the cranial and beak bones of the great spotted woodpecker and the lark bird显示文摘Woodpeckers are well able to resist head injury during repeated high speed impacts at 6-7 m s-1 with decelerations up to 1000 g.This study was designed to compare the mechanical properties,microstructures and compositions of cranial bone and beak bone of great spotted woodpecker(Dendrocopos major) and the Mongolian sky lark(Melanocorypha mongolica).Microstructures were observed using micro-computed tomography and scanning electron microscopy and their compositions were characterized by X-ray powder diffraction and Fourier-transform infrared spectroscopy.Under high stress,the cranial bone and the beak of the woodpecker exhibited distinctive mechanical features,which were associated with differences in micro-structure and composition,compared with those of the lark.Evolutionary optimization of bone micro-structure has enabled functional adaptation to the woodpecker's specific lifestyle.Its characteristic micro-structure efficiently avoids head impact injury and may provide potential clues to the prevention of brain injury using bio-inspired designs of shock-absorbing materials. | WANG LiZhen ZHANG HongQuan FAN YuBo | 2011 | Science China(Life Sciences)2011，54，11： | 9 |
| 17 | Temporal and Spatial Distribution of the Late Devonian (Famennian) Strata in the Northwestern Border of the Junggar Basin, Xinjiang, Northwestern China显示文摘The base of the Saerba Member(Mbr) of the Hongguleleng Formation(Fm.) probably lies in the Famennian Palmatolepis crepida Zone;the Longkou Mbr is probably a sedimentary wedge that thins out northwards;the Duguer Mbr has an approximate age from the upper part of the Pa.marginifera Zone or the Lower Pa.rugosa trachytera Zone through the top of the Pa.perlobata postera Zone;the Wulan Mbr has an age approximately corresponding to the whole Pa.gracilis expansa Zone.In the Bulongguoer section,the Lower Mbr of the Hongguleleng Fm.corresponds to Famennian Pa.crepida Zone through Pa.marginifera Zone;the Middle Mbr probably ranges from the Pa.r.trachytera Zone through the Pa.g.expansa Zone.The basal Namu Mbr of the Heishantou Fm.is probably the product during and after the Hangenberg Event in the upper part of the Siphonodella praesulcata Zone,which is still within the Devonian.In this context,the underlying Chasi Mbr may approximately correspond to the lower part of the S.praesulcata Zone(before the Hangenberg Event).Lateral distribution of strata indicates that the Upper Devonian in the Gennaren and Saerba areas each constitutes a structure of syncline,which differs from the previous recognition of a monocline structure. | MA Xueping ZHANG Meiqiong ZONG Pu ZHANG Yubo Lü Dan | 2017 | Acta Geologica Sinica(English Edition)2017，91，4： | 9 |
| 18 | Biomimetic delivery of signals for bone tissue engineering显示文摘Bone tissue engineering is an exciting approach to directly repair bone defects or engineer bone tissue for transplantation.Biomaterials play a pivotal role in providing a template and extracellular environment to support regenerative cells and promote tissue regeneration. A variety of signaling cues have been identified to regulate cellular activity, tissue development, and the healing process. Numerous studies and trials have shown the promise of tissue engineering, but successful translations of bone tissue engineering research into clinical applications have been limited, due in part to a lack of optimal delivery systems for these signals. Biomedical engineers are therefore highly motivated to develop biomimetic drug delivery systems, which benefit from mimicking signaling molecule release or presentation by the native extracellular matrix during development or the natural healing process. Engineered biomimetic drug delivery systems aim to provide control over the location, timing, and release kinetics of the signal molecules according to the drug's physiochemical properties and specific biological mechanisms. This article reviews biomimetic strategies in signaling delivery for bone tissue engineering, with a focus on delivery systems rather than specific molecules. Both fundamental considerations and specific design strategies are discussed with examples of recent research progress, demonstrating the significance and potential of biomimetic delivery systems for bone tissue engineering. | Ming Dang Laura Saunders Xufeng Niu Yubo Fan Peter X.Ma | 2018 | Bone Research2018，6，3： | 9 |
| 19 | A novel genetic algorithm based on all spanning trees of undirected graph for distribution network reconfiguration显示文摘Network reconfiguration is of theoretical and practical significance to guarantee safe and economical operation of distribution system.In this paper,based on all spanning trees of undirected graph,a novel genetic algorithm for electric distribution network reconfiguration is proposed.Above all,all spanning trees of simplified graph of distribution network are found.Tie branches are obtained with spanning tree subtracted from simplified graph.There is one and only one switch open on each tie branch.Decimal identity number of open switch on each tie branch is taken as the optimization variable.Therefore,the length of chromosome is very short.Each spanning tree corresponds to one subpopulation.Gene operations of each subpopulation are implemented with parallel computing method.Individuals of offspring after gene operation automatically meet with radial and connected constraints for distribution network operation.Disadvantages of conventional genetic algorithm for network reconfiguration that a large amount of unfeasible solutions are created after crossover and mutation,which result in very low searching efficiency,are completely overcome.High calculation speed and superior capability of the proposed method are validated by two test cases. | Jian ZHANG Xiaodong YUAN Yubo YUAN | 2014 | Journal of Modern Power Systems and Clean Energy2014，2，2： | 9 |
| 20 | Removal of phosphate from wastewater using alkaline residue显示文摘Alkaline residue(AR) was found to be an efficient adsorbent for phosphate removal from wastewater. The kinetic and equilibrium of phosphate removal were investigated to evaluate the performance of modified alkaline residue. After treatment by NaOH(AR-NaOH), removal performance was significantly improved, while removal performance was almost completely lost after treatment by HCl(AR-HCl). The kinetics of the removal process by all adsorbents was well characterized by the pseudo second-order model. The Langmuir model exhibited the best correlation for AR-HCl, while AR was effectively described by Freundlich model. Both models were well fitted to AR-NaOH. The maximum adsorption capacities calculated from Langmuir equation were in following manner: AR-NaOH > AR > AR-HCl. Phosphate removal by alkaline residue was pH dependent process. Mechanisms for phosphate removal mainly involved adsorption and precipitation, varied with equilibrium pH of solution. For AR-HCl, the acid equilibrium pH(< 6.0) was unfavorable for the formation of Ca-P precipitate, with adsorption as the key mechanism for phosphate removal. In contrast, for AR and ARNaOH, precipitation was the dominant mechanism for phosphate removal, due to the incrase on pH(> 8.0) after phosphate removal. The results of both XRD and SEM analysis confirmed CaHPO4·2H2O formation after phosphate removal by AR and AR-NaOH. | Yubo Yan Xiuyun Sun Fangbian Ma Jiansheng Li Jinyou Shen Weiqing Han Xiaodong Liu Lianjun Wang | 2014 | Journal of Environmental Sciences2014，26，5： | 8 |
