| 1 | Temporal and spatial variations of the active layer along the Qinghai-Tibet Highway in a permafrost region显示文摘Using monitored active layer thickness(ALT) and environmental variables of 10 observation fields along the Qinghai-Tibet Highway in permafrost region of the Qinghai-Tibetan Plateau(QTP),a model for ALT estimation was developed.The temporal and spatial characteristics of the ALT were also analyzed.The results showed that in the past 30 years ALT in the study region increased at a rate of 1.33 cm a-1.Temperatures at the upper limit of permafrost and at 50 cm depth,along with soil cumulative temperature at 5 cm depth also exhibited a rising trend.Soil heat flux increased at a rate of 0.1 Wm-2 a-1.All the above changes demonstrated that the degradation of permafrost happened in the study region on the QTP.The initial thawing date of active layer was advanced,while the initial freezing date was delayed.The number of thawing days increased to a rate of 1.18 da-1.The variations of active layer were closely related to the permafrost type,altitude,underlying surface type and soil composition.The variations were more evident in cold permafrost region than in warm permafrost region,in high-altitude region than in low-altitude region,in alpine meadow region than in alpine steppe region;and in fine-grained soil region than in coarse-grained soil region. | LI Ren ZHAO Lin DING YongJian WU TongHua XIAO Yao DU ErJi LIU GuangYue QIAO YongPing | 2012 | Chinese Science Bulletin2012，57，35： | 51 |
| 2 | Characterization of Arabidopsis MYB transcription factor gene AtMYB17 and its possible regulation by LEAFY and AGL15显示文摘MYB transcription factors compose one of the largest transcription factor families in Arabidopsis, which play important roles in various developmental processes as well as defense responses against environmental stresses.In this study, we report the characterization of AtMYB17 gene, a putative R2R3 type MYB gene family member in Arabidopsis.AtMYB17 was found exclusively localized in nuclear, with an activation domain at its C-terminus.AtMYB17 was highly expressed in inflorescences and siliques, especially at early flower developmental stages.The level of AtMYB17 transcripts was also found to increase after imbibition during seed germination and gradually concentrate to the shoot apex.Bioinformatics analysis identified several binding sites of LEAFY(LFY) and AGL15 in the promoter re-gion of AtMYB17.Promoter-GUS fusion analysis showed that the LFY binding sites were important in fine-tuning regulation of the spatio-temporal expression of AtMYB17 in transgenic plants.Moreover, AtMYB17 was up-regulated in 35S::AGL15 plants.Taken together, our data suggest that LFY may be involved in the regulation of AtMYB17, possibly together with AGL15, and thereafter in early inflorescence development and seed germination. | Yunfei Zhang Guangyu Cao Li-Jia Qu Hongya Gu | 2009 | Journal of Genetics and Genomics2009，36，2： | 24 |
| 3 | ClimateAP: an application for dynamic local downscaling of historical and future climate data in Asia Pacific显示文摘While low-to-moderate resolution gridded climate data are suitable for climate-impact modeling at global and ecosystems levels, spatial analyses conducted at local scales require climate data with increased spatial accuracy. This is particularly true for research focused on the evaluation of adaptive forest management strategies. In this study, we developed an application, Climate AP, to generate scale-free(i.e., specific to point locations) climate data for historical(1901–2015) and future(2011–2100)years and periods. Climate AP uses the best available interpolated climate data for the reference period 1961–1990 as baseline data. It downscales the baseline data from a moderate spatial resolution to scale-free point data through dynamic local elevation adjustments. It also integrates and downscales the historical and future climate data using a delta approach. In the case of future climate data, two greenhouse gas representative concentration pathways(RCP 4.5 and 8.5) and 15 general circulation models are included to allow for the assessment of alternative climate scenarios. In addition, Climate AP generates a large number of biologically relevant climate variables derived from primary monthly variables. The effectiveness of the local downscaling was determined based on the strength of the local linear regression for the estimate of lapse rate. The accuracy of the Climate AP output was evaluated through comparisons of Climate AP output against observations from 1805 weather stations in the Asia Pacific region. The local linear regression explained 70%–80% and 0%–50% of the total variation in monthly temperatures and precipitation, respectively, in most cases. Climate AP reduced prediction error by up to27% and 60% for monthly temperature and precipitation,respectively, relative to the original baselines data. The improvements for baseline portions of historical and futurewere more substantial. Applications and limitations of the software are discussed. | Tongli WANG Guangyu WANG John L.INNES Brad SEELY Baozhang CHEN | 2017 | Frontiers of Agricultural Science and Engineering2017，4，4： | 22 |
| 4 | Contemporary crustal tectonic movement in the southern Sichuan-Yunnan block based on dense GPS observation data显示文摘We analyzed 360 permanent and campaign GPS data from 1999 to 2017 in the southern Sichuan-Yunan block, and obtained crustal horizontal deformation in this region.Then, we derived the strain rate using a multi-scale spherical wavelet method.Results reveal a complex pattern of tectonic movement in the southern Sichuan-Yunnan block.Compared to the stable Eurasian plate, the maximum rate of the horizontal deformation in the southern Sichuan-Yunnan block is approximately 22 mm/a.The Xiaojiang fault shows a significantly lower deformation—a left-lateral strike-slip movement of 9.5 mm/a.The Honghe fault clearly shows a complex segmental deformation from the north to south.The northern Honghe fault shows 4.3 mm/a right strike-slip with 6.7 mm/a extension; the southern Honghe fault shows 1.9 mm/a right strike-slip with 1.9 mm/a extension; the junction zone in the Honghe and Lijiang–Xiaojinhe faults shows an obvious clockwise-rotation deformation.The strain calculation results reveal that the maximum shear-strain rate in this region reaches 70 nstrain/a, concentrated around the Xiaojiang fault and at the junction of the Honghe and Lijiang–Xiaojinhe faults.We note that most of the earthquakes with magnitudes of 4 and above that occurred in this region were within the high shear strain-rate zones and the strain rate gradient boundary zone, which indicates that the magnitude of strain accumulation is closely related to the seismic activities.Comparison of the fast shear-wave polarization direction of the upper-crust with the upper-mantle anisotropy and the direction of the surface principal compressive strain rate obtained from the inversion of the GPS data reveals that the direction of the surface principal compressive strain is basically consistent with the fast shear-wave polarization direction of the upper crust anisotropy, but different from the polarization direction of the upper mantle.Our results support the hypothesis that the principal elements of the deformation mechanism in the southern Sichuan-Yunnan block are decoupling between the upper and lower crust and ductile flow in the lower crust. | HongLin Jin Yuan Gao XiaoNing Su GuangYu Fu | 2019 | Earth and Planetary Physics2019，3，1： | 18 |
| 5 | Epidemiological and risk analysis of the H7N9 subtype influenza outbreak in China at its early stage显示文摘Dozens of human cases infected with H7N9 subtype avian influenza virus (AIV) have been confirmed in China since March, 2013. Distribution data of sexes, ages, professions and regions of the cases were analyzed in this report. The results showed that the elderly cases, especially the male elderly, were significantly more than expected, which is different from human cases of H5N1 avian influenza and human cases of the pandemic H1N1 influenza. The outbreak was rated as a Grade Ⅲ (severe) outbreak, and it would evolve into a Grade IV (very severe) outbreak soon, using a method reported previously. The H7N9 AIV will probably circulate in humans, birds and pigs for years. Moreover, with the driving force of natural selection, the virus will probably evolve into highly pathogenic AIV in birds, and into a deadly pandemic influenza virus in humans. Therefore, the H7N9 outbreak has been assumed severe, and it is likely to become very or extremely severe in the future, highlighting the emergent need of forceful scientific measures to eliminate any infected animal flocks. We also described two possible mild scenarios of the future evolution of the outbreak. | ZHUANG QingYe WANG SuChun WU MeiLi LIU Shuo JIANG WenMing HOU GuangYu LI JinPing WANG KaiCheng YU JianMin CHEN JiMing CHEN JiWang | 2013 | Chinese Science Bulletin2013，58，26： | 18 |
| 6 | Hyperbaric oxygen therapy improves cognitive functioning after brain injury显示文摘Hyperbaric oxygen therapy has been widely applied and recognized in the treatment of brain injury;however,the correlation between the protective effect of hyperbaric oxygen therapy and changes of metabolites in the brain remains unclear.To investigate the effect and potential mechanism of hyperbaric oxygen therapy on cognitive functioning in rats,we established traumatic brain injury models using Feeney’s free falling method.We treated rat models with hyperbaric oxygen therapy at 0.2 MPa for 60 minutes per day.The Morris water maze test for spatial navigation showed that the average escape latency was significantly prolonged and cognitive function decreased in rats with brain injury.After treatment with hyperbaric oxygen therapy for 1 and 2 weeks,the rats’spatial learning and memory abilities were improved.Hydrogen proton magnetic resonance spectroscopy analysis showed that the N-acetylaspartate/creatine ratio in the hippocampal CA3 region was significantly increased at 1 week,and the N-acetylaspartate/choline ratio was significantly increased at2 weeks after hyperbaric oxygen therapy.Nissl staining and immunohistochemical staining showed that the number of nerve cells and Nissl bodies in the hippocampal CA3 region was significantly increased,and glial fibrillary acidic protein positive cells were decreased after a 2-week hyperbaric oxygen therapy treatment.Our findings indicate that hyperbaric oxygen therapy significantly improves cognitive functioning in rats with traumatic brain injury,and the potential mechanism is mediated by metabolic changes and nerve cell restoration in the hippocampal CA3 region. | Su Liu Guangyu Shen Shukun Deng Xiubin Wang Qinfeng Wu Aisong Guo | 2013 | Neural Regeneration Research2013，8，35： | 16 |
| 7 | High-speed colour-converting photodetector with all-inorganic CsPbBr_(3) perovskite nanocrystals for ultraviolet light communication显示文摘Optical wireless communication(OWC)using the ultra-broad spectrum of the visible-to-ultraviolet(UV)wavelength region remains a vital field of research for mitigating the saturated bandwidth of radio-frequency(RF)communication.However,the lack of an efficient UV photodetection methodology hinders the development of UV-based communication.The key technological impediment is related to the low UV-photon absorption in existing silicon photodetectors,which offer low-cost and mature platforms.To address this technology gap,we report a hybrid Sibased photodetection scheme by incorporating CsPbBr_(3) perovskite nanocrystals(NCs)with a high photoluminescence quantum yield(PLQY)and a fast photoluminescence(PL)decay time as a UV-to-visible colourconverting layer for high-speed solar-blind UV communication.The facile formation of drop-cast CsPbBr_(3) perovskite NCs leads to a high PLQY of up to ~73% and strong absorption in the UV region.With the addition of the NC layer,a nearly threefold improvement in the responsivity and an increase of ~25% in the external quantum efficiency(EQE)of the solar-blind region compared to a commercial silicon-based photodetector were observed.Moreover,timeresolved photoluminescence measurements demonstrated a decay time of 4.5 ns under a 372-nm UV excitation source,thus elucidating the potential of this layer as a fast colour-converting layer.A high data rate of up to 34 Mbps in solar-blind communication was achieved using the hybrid CsPbBr_(3)-silicon photodetection scheme in conjunction with a 278-nm UVC light-emitting diode(LED).These findings demonstrate the feasibility of an integrated high-speed photoreceiver design of a composition-tuneable perovskite-based phosphor and a low-cost silicon-based photodetector for UV communication. | Chun Hong Kang Ibrahim Dursun Guangyu Liu Lutfan Sinatra Xiaobin Sun Meiwei Kong Jun Pan Partha Maity Ee-Ning Ooi Tien Khee Ng Omar F.Mohammed Osman M.Bakr Boon S.Ooi | 2019 | Light(Science & Applications)2019，8，1： | 14 |
| 8 | Comparative study on the effects and efficiencies of three sublimation drying methods for mushrooms显示文摘Freeze drying(FD)yields the best quality of dried mushrooms but needs long drying time and higher cost.Air drying(AD)gives relatively poor product quality.In order to achieve faster drying along with high product quality,microwave freeze drying(MFD)and atmospheric freeze drying(AFD)were developed to dry mushrooms.By comparison of three sublimation drying processes,it was concluded that FD could lead to the best product quality,but cost the highest energy consumption.AFD mushrooms had the worst quality and longest drying time,but the lowest energy consumption.Compared with FD and AFD,MFD could get relatively acceptable quality and drying efficiency.As a result,MFD can be used to replace traditional FD,and AFD also should be popularized because of its low energy consumption. | Duan Xu Liu Wei Ren Guangyue Liu Wenchao Liu Yunhong | 2015 | International Journal of Agricultural and Biological Engineering2015，8，1： | 13 |

| 10 | Additive manufacturing of Ti-6Al-4V lattice structures with high structural integrity under large compressive deformation显示文摘Additively manufactured Ti-6 Al-4 V lattice structures have found important niche applications. However, they often show insufficient compressive ductility or insufficient structural integrity. In this study,a batch of 45 octahedral Ti-6 Al-4 V lattice structures was manufactured in three different strut diameters(0.5, 1.0, 1.5 mm) by selective electron beam melting(SEBM). The influence of post-SEBM annealing on the compressive deformation characteristics of the lattice structure was investigated. The as-built Ti-6 Al-4 V lattices fragmented when the compressive strain reached 13%–23% depending on strut diameter.Annealing at 950?C(β transus temperature: 995?C) only slightly improved the compressive ductility of the lattice structures. However, annealing at 1050?C(β-annealing) fundamentally changed the compressive deformation mode of the lattice structures. The resultant compressive stress-strain curve was featured by a long smooth plateau and no facture occurred even after significant densification of the lattice structure had taken place(>50% of compressive strain). | Kun Yang Jian Wang Liang Jia Guangyu Yang Huiping Tang Yuanyuan Li | 2019 | Journal of Materials Science & Technology2019，35，2： | 12 |
| 11 | The influence of particle size and concentration combined with pH on coagulation mechanisms显示文摘In order to evaluate the influence of particle size and particle concentration on the coagulation process, two kinds of particle suspensions, nanoparticles and microparticles,were employed to investigate the effect of particle size on coagulation mechanisms with varying coagulation parameters. Results showed that it is easier for nanoparticles to cause self-aggregation because of Brownian motion, while interception and sedimentation are the mainly physical processes affecting particle transport for microparticles, so they are more stable and disperse more easily. The particle size distribution and particle concentration had distinct influence on the coagulation mechanisms. Under neutral conditions, as the amount of coagulant increased, the coagulation mechanism for nanoparticles changed from charge neutralization to sweep flocculation and the nanoparticles became destabilized, re-stabilized and again destabilized. For microparticles, although the coagulation mechanism was the same as that of nanoparticles, the increased rate of aluminum hydroxide precipitation exceeded the adsorption of incipiently formed soluble alum species, resulting in the disappearance of the re-stabilization zone. Under acidic conditions, Brownian motion dominates for nanoparticles at low particle concentrations, while sweep flocculation is predominant at high particle concentrations. As for microparticles, charge neutralization and sweep flocculation are the mechanisms for low and high particle concentrations respectively.Under alkaline condition, although the mechanisms for both nano-and microparticles are the same, the morphology of flocs and the kinetics of floc formation are different. At low particle concentrations, nanoparticles have larger growth rate and final size of flocs, while at high particle concentrations, nanoparticles have higher fractal dimension and recovery factors. | Hongyan Sun Ruyuan Jiao Hui Xu Guangyu An Dongsheng Wang | 2019 | Journal of Environmental Sciences2019，31，8： | 12 |
| 12 | A novel human mAb (MERS-GD27) provides prophylactic and postexposure efficacy in MERS-CoV susceptible mice显示文摘Dear Editor,Since September 2012, the Middle East respiratory syndrome coronavirus (MERS-CoV) cases have been reported in more than 27 countries, and more than 2,000 cases have been confirmed in the laboratory (http://gffzz36b398b81f8a4a4ch0b66bp0cqcfw69qb.ffgz.tsg.suse.edu.cn/emergencies/mers-cov/en/). MERS-CoV causes an acute and severe respiratory illness with a high mortality rate(~35%) in humans (Shi et al., 2017, Zaki et al., 2012).Neutralizing antibodies targeting the spike of MERS-CoV have been shown to be a therapeutic option for treatment of lethal disease (Agrawal et al., 2016, Ying et al., 2014). | Peihua Niu Guangyu Zhao Yao Deng Shihui Sun Wenling Wang Yusen Zhou Wenjie Tan | 2018 | Science China(Life Sciences)2018，61，10： | 11 |
| 13 | An effective route to improve the catalytic performance of SAPO-34 in the methanol-to-olefin reaction显示文摘An effective route to improve the catalytic performance of SAPO-34 in the methanol-to-olefin reaction by simple oxalic acid treatment was investigated.The samples were characterized by XRD,SEM,N2 adsorption-desorption,XRF,TG,29Si MAS NMR and NH3-TPD techniques.The results indicated that the external surface acidity of SAPO-34 was finely tuned by oxalic acid treatment,and the selectivity to C2H4 on SAPO-34 and the catalyst lifetime in the methanol-to-olefin reaction were greatly improved. | Guangyu Liu Peng Tian Qinhua Xia Zhongmin Liu | 2012 | Journal of Natural Gas Chemistry2012，21，4： | 11 |

| 15 | Corrosion mechanism investigation of TiN/Ti coating and TC4 alloy for aircraft compressor application显示文摘It is imperative to develop multifunctional erosion and corrosion resistant coatings for compressor blades of aircraft engines in harsh environment.PVD(Physical Vapor Deposition)technology has the advances in processing erosion-resistant coatings;however,the performance of PVD coatings to combat corrosion depends on various coating defects.Determining and comparing the corrosion performances of PVD TiN/Ti coating and uncoated TC4 alloy was the main objective of present work.The 960 h salt spray corrosion and 116 h hot corrosion tests were conducted to simulate the grounding and working environments of the aircraft compressors.The corrosion mechanisms due to the coating defects such as pinhole,columnar boundary and large grain were analyzed based on the OM,Confocal microscope,electrochemical measurements,SEM,XRD and EDS results.Owing to the disordered state associated with the columnar boundary and the coating defect,nitrogen could be easily replaced by oxygen in the hot corrosion process,these structures were channels for fast diffusion of oxygen.Moreover,the Gibbs energy changes of Ti oxidation and TiN oxidation were thermodynamically calculated according to the working condition of aircraft compressors,and considerable research effort was focused on mapping out the phase diagram of Ti,TiN and high pressure gases.The findings of this research can provide insights into developing multifunctional coatings for future aircraft engines. | Zhiping SUN Guangyu HE Qingjie MENG Yuqin LI Xiaodong TIAN | 2020 | Chinese Journal of Aeronautics2020，33，6： | 11 |

| 17 | Historic distribution and driving factors of human-caused fires in the Chinese boreal forest between 1972 and 2005显示文摘Aims The pattern and driving factors of forest fires are of interest for fire occurrence prediction and forest fire management.The aims of the study were:(i)to describe the history of human-caused fires by season and size of burned area over time;(ii)to identify the spatial patterns of human-caused fires and test for the existence of‘hotspots’to determine their exact locations in the Daxing’an mountains;(iii)to determine the driving factors that determine the spatial distribution and the possibility of human-caused fire occurrence.Methods In this study,K-function and Kernel density estimation were used to analyze the spatial pattern of human-caused fires.The analysis was conducted in s-plus and arcgIs environments,respectively.The analysis of driving factors was performed in SPSS 19.0 based on a logistic regression model.The variables used to identify factors that influence fire occurrence included vegetation types,meteorological conditions,socioeconomic factors,topography and infrastructure factors,which were extracted and collected through the spatial analysis mode of arcgIs and from official statistics,respectively.Important Findings The annual number of human-caused fires and the area burnt have declined since 1987 due to the implementation of a forest fire protection act.There were significant spatial heterogeneity and seasonal variations in the distribution of human-caused fires in the Daxing’an mountains.The heterogeneity was caused by elevation,distance to the nearest railway,forest type and temperature.a logistic regression model was developed to predict the likelihood of human-caused fire occurrence in the Daxing’an mountains;its global accuracy attained 64.8%.The model was thus comparable to other relevant studies. | Futao Guo John L.Innes Guangyu Wang Xiangqing Ma Long Sun Haiqing Hu Zhangwen Su | 2015 | Journal of Plant Ecology2015，8，5： | 10 |
| 18 | NEW NONSTANDARD JOB SHOP SCHEDULING ALGORITHM显示文摘Considering the complex constraint between operations in nonstandard job shop scheduling problem (NJSSP), critical path of job manufacturing tree is determined according to priority scheduling function constructed. Operations are divided into dependent operations and independent operations with the idea of subsection, and corresponding scheduling strategy is put forward according to operation characteristic in the segment and the complementarities of identical function machines. Forward greedy rule is adopted mainly for dependent operations to make operations arranged in the right position of machine selected, then each operation can be processed as early as possible, and the total processing time of job can be shortened as much as possible. For independent operations optimum scheduling rule is adopted mainly, the inserting position of operations will be determined according to the gap that the processing time of operations is subtracted from idle time of machine, and the operation will be inserted in the position with minimal gap. Experiments show, under the same conditions, the result that operations are scheduled according to the object function constructed, and the scheduling strategy adopted is better than the result that operations are scheduled according to efficiency scheduling algorithm. | XIE Zhiqiang YE Guangjie ZHANG Dali TAN Guangyu | 2008 | Chinese Journal of Mechanical Engineering2008，21，4： | 10 |
| 19 | Two-photon-excited near-infrared emissive carbon dotsas multifunctional agents for fluorescence imaging andphotothermal therapy显示文摘C dots (CDs) have shown great potential in bioimaging and phototherapy.However, it is challenging to manipulate their fluorescent properties andtherapeutic efficacy to satisfy the requirements for clinic applications. In thisstudy, we prepared S, Se-codoped CDs via a hydrothermal method anddemonstrated that the doping resulted in excitation wavelength-independentnear-infrared (NIR) emissions of the CDs, with peaks at 731 and 820 nm.Significantly, the CDs exhibited a photothermal conversion efficiency of -58.2%,which is the highest reported value for C nanostructures and is comparable tothat of Au nanostructures. Moreover, the CDs had a large two-photon absorptioncross section (-30,045 GM), which allowed NIR emissions and the photothermalconversion of the CDs through the two-photon excitation (TPE) mechanism. Invitro and in vivo tests suggested that CDs can function as new multi functionalphototheranostic agents for the TPE fluorescence imaging and photothermaltheraov of cancer cells. | Minhuan Lan Shaojing Zhao Zhenyu Zhang Li Yan Liang Guo Guangle Niu Jinfeng Zhang Junfang Zhao Hongyan Zhang Pengfei Wang Guangyu Zhu Chun-Sing Lee Wenjun Zhang | 2017 | Nano Research2017，10，9： | 9 |
| 20 | Dynamics of major air pollutants from crop residue burning in China's Mainland,2000–2014显示文摘Based on satellite image data and China's Statistical Yearbooks(2000 to 2014), we estimated the total mass of crop residue burned, and the proportion of residue burned in the field vs.indoors as domestic fuel. The total emissions of various pollutants from the burning of crop residue were estimated for 2000-2014 using the emission factor method. The results indicate that the total amount of crop residue and average burned mass were 8690.9 Tg and4914.6 Tg, respectively. The total amount of emitted pollutants including CO_2, CO, NOx,VOCs, PM_(2.5), OC(organic carbon), EC(element carbon) and TC(total carbon) were 4212.4–8440.9 Tg, 192.8–579.4 Tg, 4.8–19.4 Tg, 18.6–61.3 Tg, 18.8–49.7 Tg, 6.7–31.3 Tg, 2.3–4.7 Tg, and8.5–34.1 Tg, respectively. The emissions of pollutants released from crop residue burning were found to be spatially variable, with the burning of crop residue mainly occurring in Northeast, North and South China. In addition, pollutant emissions per unit area(10 km ×10 km) were mostly concentrated in the central and eastern regions of China. Emissions of CO_2, NOx, VOCs, OC and TC were mainly from rice straw burning, while burning of corn and wheat residues contributed most to emissions of CO, PM_(2.5) and EC. The increased ratio of PM_(2.5) emissions from crop residue burning to the total emitted from industry during the study period is attributed to the implementation of strict emissions management policies in Chinese industry. This study also provides baseline data for assessment of the regional atmospheric environment. | Quanfeng Jin Xiangqing Ma Guangyu Wang Xiajie Yang Futao Guo | 2018 | Journal of Environmental Sciences2018，30，8： | 9 |
