| 1 | Mapping and validation of a dominant salt tolerance gene in the cultivated soybean(Glycine max) variety Tiefeng 8显示文摘Salt is an abiotic stress factor that strongly affects soybean growth and production. A single dominant gene has been shown to confer salt tolerance in the soybean cultivar Tiefeng 8.The objective of the present study was to genetically map the salt-tolerance gene in an F2:3population and a recombinant inbred line(RIL) population derived from a cross between two cultivated soybeans, Tiefeng 8(tolerant) and 85-140(sensitive). The F2:3families and RILs were treated with 200 mmol L-1Na Cl to evaluate salt tolerance. The F2:3population showed 1(42 tolerant): 2(132 segregating): 1(65 sensitive) segregation, indicating a single dominant gene for salt tolerance in Tiefeng 8. A sequence-characterized amplified region(SCAR) marker from a previously identified random amplified polymorphic DNA(RAPD)marker and four insertion/deletion polymorphism(In Del) markers were developed within the mapping region. Using these markers along with SSR markers, the salt-tolerance gene was mapped within 209 kb flanked by SCAR marker QS08064 and SSR marker Barcsoyssr_3_1301 on chromosome 3. Three markers that cosegregated with the salt tolerance gene and SCAR marker QS08064 were used to genotype 35 tolerant and 23 sensitive soybean accessions. These markers showed selection efficiencies of 76.2% to94.2%. The results indicate that these markers will be useful for marker-assisted breeding and facilitating map-based cloning of the salt tolerance gene in soybean. | Rongxia Guan Jiangang Chen Jinghan Jiang Guangyu Liu Ying Liu Lei Tian Lili Yu Ruzhen Chang Li-juan Qiu | 2014 | The Crop Journal2014，2，6： | 5 |
| 2 | Frequency-multiplexing photon-counting multi-beam LiDAR显示文摘We report a frequency-multiplexing method for multi-beam photon-counting light detection and ranging(Li DAR),where only one single-pixel single-photon detector is employed to simultaneously detect the multibeam echoes.In this frequency-multiplexing multi-beam Li DAR,each beam is from an independent laser source with different repetition rates and independent phases.As a result,the photon counts from different beams could be discriminated from each other due to the strong correlation between the laser pulses and their respective echo photons.A 16-beam Li DAR system was demonstrated in three-dimensional laser imaging with 16 pulsed laser diodes at 850 nm and one single-photon detector based on a Si-avalanche photodiode.This frequencymultiplexing method can greatly reduce the number of single-photon detectors in multi-beam Li DAR systems,which may be useful for low-cost and eye-safe Li DAR applications. | TIANXIANG ZHENG GUANGYUE SHEN ZHAOHUI LI LEI YANG HAIYAN ZHANG E WU GUANG WU | 2019 | Photonics Research2019，7，12： | 4 |

| 4 | Microstructure evolution,mechanical properties and diffusion behaviour of Mg-6Zn-2Gd-0.5Zr alloy during homogenization显示文摘The microstructure evolution and mechanical properties of Mg-6 Zn-2 Gd-0.5 Zr alloy during homogenization treatment were investigated. The as-cast alloy was found to be composed of dendritic primaryα-Mg matrix, α-Mg +W(Mg_3Zn_3Gd_2) eutectic along grain boundaries, and icosahedral quasicrystalline I(Mg_3Zn_6Gd) phase within α-Mg matrix. During homogenization process, α-Mg +W(Mg_3Zn_3Gd_2) eutectic and I phase gradually dissolved into a-Mg matrix, while some rod-like rare earth hydrides(GdH2)formed within α-Mg matrix. Both the tensile yield strength and the elongation showed a similar tendency as a function of homogenization temperature and holding time. The optimized homogenization parameter was determined to be 505℃ for 16 h according to the microstructure evolution. Furthermore,the diffusion kinetics equation of the solute elements derived from the Gauss model was established to predict the segregation ratio of Gd element as a function of holding time, which was proved to be effective to evaluate the homogenization effect of the experimental alloy. | Lei Xiao Guangyu Yang Yang Liu Shifeng Luo Wanqi Jie | 2018 | Journal of Materials Science & Technology2018，34，12： | 3 |
| 5 | Polyamine oxidase 3 is involved in salt tolerance at the germination stage in rice显示文摘Soil salinity inhibits seed germination and reduces seedling survival rate,resulting in significant yield reductions in crops.Here,we report the identification of a polyamine oxidase,OsPAO3,conferring salt tolerance at the germination stage in rice(Oryza sativa L.),through map-based cloning approach.OsPAO3 is up-regulated under salt stress at the germination stage and highly expressed in various organs.Overexpression of OsPAO3 increases activity of polyamine oxidases,enhancing the polyamine content in seed coleoptiles.Increased polyamine may lead to the enhance of the activity of ROS-scavenging enzymes to eliminate over-accumulated H;O;and to reduce Na;content in seed coleoptiles to maintain ion homeostasis and weaken Na;damage.These changes resulted in stronger salt tolerance at the germination stage in rice.Our findings not only provide a unique gene for breeding new salt-tolerant rice cultivars but also help to elucidate the mechanism of salt tolerance in rice. | Guangyu Liu Wanxia Jiang Lei Tian Yongcai Fu Lubin Tan Zuofeng Zhu Chuanqing Sun Fengxia Liu | 2022 | Journal of Genetics and Genomics2022，49，5： | 2 |
| 6 | Biosynthetic CdS-Thiobacillus thioparus hybrid for solar-driven carbon dioxide fixation显示文摘Synergistically combining biological whole-cell bacteria with man-made semiconductor materials innovates the way for sustainable solar-driven CO_(2)fixation,showing great promise to break through the bottleneck in traditional chemical photocatalyst systems.However,most of the biohybrids require uneconomical organic nutrients and anaerobic conditions for the successful cultivation of the bacteria to sustain the CO_(2)fixation,which severely limits their economic viability and applicability for practical application.Herein,we present an inorganic-biological hybrid system composed of obligate autotrophic bacteria Thiobacillus thioparus(T.thioparus)and CdS nanoparticles(NPs)biologically precipitated on the bacterial surface,which can achieve efficient CO_(2)fixation based entirely on cost-effective inorganic salts and without the restriction of anaerobic conditions.The optimized interface between CdS NPs and T.thioparus formed by biological precipitation plays an essential role for T.thioparus efficiently receiving photogenerated electrons from CdS NPs and thus changing the autotrophic way from chemoautotroph to photoautotroph.As a result,the CdS-T.thioparus biohybrid realizes the solar-driven CO_(2)fixation to produce multi-carbon glutamate synthase and biomass under visible-light irradiation with CO_(2)as the only carbon source.This work provides significant inspiration for the further exploration of the solar-driven self-replicating biocatalytic system to achieve CO_(2)fixation and conversion. | Guangyu Liu Feng Gao Hongwei Zhang Lei Wang Chao Gao Yujie Xiong | 2023 | Nano Research2023，16，4： | 2 |

| 8 | Degradation kinetics of functional components of honeysuckle flowers during controlled-atmosphere heat pump drying显示文摘To investigate the change law of functional components and exterior color of honeysuckle flowers(HF)during controlled-atmosphere heat pump drying,nitrogen was used as drying medium in this study to reduce the oxygen concentration.The influences of drying temperature,HF’s loading amount and oxygen concentration on chlorogenic acid content,cynaroside content and L value(on behalf of browning degree)were explored,and the degradation kinetics models of chlorogenic acid and cynaroside were constructed.The results showed that chlorogenic acid content,cynaroside content and L value decreased with the rise of temperature,HF’s loading amount and oxygen concentration.The degradation kinetics models of chlorogenic acid and cynaroside during the drying process were established through introducing an exponent r related to time t in the first order reaction kinetics equation.The models had good fitting precision and can be used to predict the degradation law of chlorogenic acid and cynaroside. | Luo Lei Yang Bin Zhu Wenxue Ren Guangyue Duan Xu Kang Xinyan | 2016 | International Journal of Agricultural and Biological Engineering2016，9，4： | 1 |

| 12 | The Establishment and Application of Mobile Electronic Surveillance System for Infectious Diseases with the Help of China—Sierra Leone,2016-Present显示文摘Introduction:Infectious disease surveillance has long been a challenge for low-income countries like Sierra Leone.Traditional approaches based on paper and Short Message Service(SMS)were subject to severe delays in obtaining,transmitting,and analyzing information.Methods:During the China aid operation for fighting Ebola since the end of 2014,a mobile electronic surveillance system for infectious diseases(MESSID)was developed in collaboration with the Republic of Sierra Leone Armed Forces(RSLAF),which comprised an Android-based reporting system and a complementary web-based program designed by Active Server Page.NET(ASP.NET)with the main functions including surveillance,real-time reporting,and risk assessment of infectious diseases.Results:MESSID was successfully registered in June 2016 and had been used by all medical and health institutions in RSLAF.From June 1,2016 to July 5,2021,34,419 cases were diagnosed with 47 infectious diseases of 5 categories,with a total of 42 clinical symptoms.Compared to traditional approaches based on paper and SMS,the MESSID showed flexibility,high efficiency,convenience,and acceptability.Discussion:MESSID is an accessible tool for surveillance of infectious diseases in Sierra Leone and possibly in other African countries with similar needs,capable of improving timeliness of disease reporting,thus rendering a timely outbreak detection and response. | Guangyu Zhao Haorong Chen Yanfeng Yan Jiafu Jiang Lei Lin Baogui Jiang Foday Sahr Stephen Sevalie Qiang Xu Jinjin Chen Henry Saidu Bangura Kandeh Bassie Kargbo Yajun Song Wei Liu Liqun Fang Yansong Sun | 2021 | China CDC weekly2021，3，36： | 1 |
| 13 | Bandgap broadening at grain boundaries in single-layer MoS2显示文摘Two-dimensional semiconducting transition-metal dichalcogenides have attractedconsiderable interest owing to their unique physical properties and futuredevice applications. In particular, grain boundaries (GBs) have been oftenobserved in single-layer MoS2 grown via chemical vapor deposition, which cansignificantly influence the material properties. In this study, we examined theelectronic structures of various GBs in single-layer MoS2 grown on highlyoriented pyrolytic graphite using low-temperature scanning tunneling microscopy/spectroscopy. By measuring the local density of states of a series of GBs with tiltangles ranging from 0° to 25°, we found that the bandgaps at the GBs can beeither broadened or narrowed with respect to the intrinsic single-layer MoS2.The bandgap broadening shows that the GBs can become more insulating,which may directly influence the transport properties of nanodevices based onpolycrystalline single-layer MoS2 and be useful for optoelectronics. | Dongfei Wang Hua Yu Lei Tao Wende Xiao Peng Fan Tingting Zhang Mengzhou Liao Wei Guo Dongxia Shi Shixuan Du Guangyu Zhang Hongjun Gao | 2018 | Nano Research2018，11，11： | 1 |
| 14 | Rules of Changes in Soil Nutrients and Enzyme Activities of Larix principis-rupprechtii in Different Forest Ages显示文摘In this study,three different ages of Larix principis-rupprechtii forests in 5,10 and 20 years were selected as the research objects,and the changes in soil nutrient and soil enzyme activities in different growth stages were analyzed. The results showed that the contents of organic matter and available phosphorus in the soil of different growth stages showed a significant downward trend with the increase of soil depth.For different forest ages in the same soil layer,the soil available phosphorus content declined with the increase of the forest age. The organic matter content of 40-60 cm in 20 years of forest age was the lowest in July,which was 4. 17 g/kg,significantly lower than that in other soil layers. Besides,the soil available phosphorus content of 5 years of forest age reached the maximum in July,with an average of 4. 44 mg/kg,which was higher than the available phosphorus content in soil in May and September,but the difference between the three months was not significant. The changes in ammonium nitrogen and nitrate nitrogen content in soil with different forest ages were consistent with the changes in the soil depth,showing a downward trend. In the new leaf stage,the ammonium nitrogen content of the L. principis-rupprechtii forest land in5 years of age at 20-40 and 40-60 cm of the soil depth was 13. 47 and 9. 09 mg/kg,respectively,which was 46. 9% and 64. 2% lower than that at 0-20 cm( 25. 36 mg/kg) of the soil depth. The soil nitrate nitrogen content of 20 years of forest age was 19. 24 mg/kg,which was25. 8% lower than that of 10 years of forest age,showing significant difference( P < 0. 05). In addition,with the increase of the age of L. principis-rupprechtii,soil catalase( CAT),alkaline phosphatase( ALP) and urease( Ure) decreased,and the decline of ALP was slow,while CAT and Ure decreased significantly. In summary,it is concluded that the soil fertility of forest land declined with the increase of forest age on the basis of change trend of soil nutrient and soil enzyme activity in the surveyed forest age. | Shenglan YE Guangyu LEI | 2019 | Asian Agricultural Research2019，11，4： | 1 |
| 15 | Smart light-responsive hierarchical metal organic frameworks constructed mixed matrix membranes for efficient gas separation显示文摘One type of new light-responsive hierarchical metal organic framework(MOF) has been successfully prepared using Co(NO_(3))_(3)·6H_(2)O as the metal salt and 4,4’-azobenzenedicarboxylic acid as the ligand by microwave method for the first time. It is found that MOF [Co(Az DC)] exhibits a light-responsive characteristic to SO_(2)adsorption due to the presence of azo group from the ligand. The light-responsive hierarchical MOFs are incorporated into Matrimid■ 5218(PI) matrix to prepare mixed matrix membranes(MMMs) for gas separation application. The morphology, crystallinity, chain mobility and thermal stability of MMMs are explored. Results show that Co(Az DC) may elevate both the CO_(2)(SO_(2)) permeability and CO_(2)(SO_(2))/N_(2)selectivity of the MMMs. In particular,the Co(Az DC) doped MMMs exhibit the significantly improved CO_(2)(SO_(2))/N_(2)selectivity from 33(123) for PI control membrane to 78(420) for MMMs, overcoming the 2008 Robeson upper bound for CO_(2)/N_(2)system. Sizesieving effect of Co(Az DC) with pore size 0.35 nm enhances the selectivity, while the –N=N– group from Co(Az DC) shows affinity to CO_(2)molecular rather than N_(2), also elevating selectivity of MMMs. In brief, enhanced selectivity of high-performance membrane is attributed to incorporation of Co(Az DC) particles, which displays synergistic effects both in size-sieving and CO_(2)-philic interaction for CO_(2)/N_(2)separation. Smart highly selective interface is constructed in MMMs by switching the configuration of MOFs from cis to trans. The SO_(2)permeability and SO_(2)/N_(2)selectivity of MMMs are investigated under both visible light and ultraviolet light states, and the SO_(2)/N_(2)separation performance under visible light is notably improved in comparison with that under ultraviolet light state. | Qingping Xin Xueting Cao Dandan Huang Shuo Li Xinghui Zhang Guangyu Xuan Mengting Wei Lei Zhang Xiaoli Ding Yuzhong Zhang | 2022 | Green Chemical Engineering2022，3，1： | 0 |
| 16 | Assessment and management of the performance risk of a pilot reclaimed water disinfection process显示文摘Chlorination disinfection has been widely used in reclaimed water treatment plants to ensure water quality. In order to assess the downstream quality risk of a running reclaimed water disinfection process, a set of dynamic equations was developed to simulate reactions in the disinfection process concerning variables of bacteria, chemical oxygen demand(COD), ammonia and monochloramine.The model was calibrated by the observations obtained from a pilot disinfection process which was designed to simulate the actual process in a reclaimed water treatment plant. A Monte Carlo algorithm was applied to calculate the predictive efuent quality distributions that were used in the established hierarchical assessment system for the downstream quality risk, and the key factors afecting the downstream quality risk were defined using the Regional Sensitivity Analysis method. The results showed that the seasonal upstream quality variation caused considerable downstream quality risk; the efuent ammonia was significantly influenced by its upstream concentration; the upstream COD was a key factor determining the process efuent risk of bacterial, COD and residual disinfectant indexes; and lower COD and ammonia concentrations in the influent would mean better downstream quality. | Guangyu Zhou Xinhua Zhao Lei Zhang Qing Wu | 2013 | Journal of Environmental Sciences2013，25，10： | 0 |
| 17 | Dynamic profiles of DNA methylation and the interaction with histone acetylation during fiber cell initiation of Gossypium hirsutum显示文摘Background:Fiber,as the main product of cotton,provides main raw material for the textile industry.Many key factors have been revealed a significant role in fiber cell development including Myb proteins,phytohormones,fatty acid metabolites,and epigenetic modifications.DNA methylation is one of the important epigenetic modifications to regulate plant development and responses to abiotic or biotic stimuli.In general,DNA methylation consisting of 5mC and 6mA regulates the chromatin structure and gene transcription to affect plant development,however,the detailed role and underlying mechanism of DNA methylation in the fiber development of cotton are yet vague.Results:Here,systematical study of the 5mC and 6mA DNA methylation profiles during the fiber initiation period of Xu142 and its glabrous mutant Xu142fl represented a clear alteration of global DNA methylation associated with fiber cell initiation.Then,the genome-wide identification of genes responsible for methylation regulation at the fifth carbon of cytosine and the sixth carbon of adenine of DNA was operated in Gossypium hirsutum.As a result,13,10,6,and 17 genes were identified for 5mC methylation,5mC demethylation,6mA methylation,and 6mA demethylation,respectively.We then investigated the tissue expression pattern of all these genes,and some genes showed higher expression levels in fiber initiation,among which some displayed a significant change in transcription between Xu142 and Xu142fl.The possible interaction between histone acetylation and DNA methylation in fiber initiation through in vitro culture was studied by dot blot,and the results showed that repressed histone deacetylation by Trichostatin A(TSA)inhibited the global DNA methylation,and some causal genes(e.g.,GhDMT13,GhDAMT2,GhALKBH12,GhDM7)were also identified.Conclusions:In this study,all the findings indicated the interplay between histone acetylation and DNA methylation,supporting their important roles and providing precious clues for the epigenetic modifications associated with DNA methylation in the fiber development of cotton. | CHEN Guangyu LI Yonghui WEI Zhenzhen GAN Lei LIU Jisheng WANG Zhi | 2022 | Journal of Cotton Research2022，5，1： | 0 |
| 18 | Sampling visual SLAM with a wide-angle camera for legged mobile robots显示文摘Precise localisation and navigation are the two most important tasks for mobile robots.Visual simultaneous localisation and mapping(VSLAM)is useful in localisation systems of mobile robots.The wide-angle camera has a broad field of vision and more abundant information on images,so it is widely used in mobile robots,including legged robots.However,wide-angle cameras are more complicated than ordinary cameras in the design of visual localisation systems,and higher requirements and challenges are put forward for VSLAM technologies based on wide-angle cameras.In order to resolve the problem of distortion in wide-angle images and improve the accuracy of localisation,a sampling VSLAM based on a wide-angle camera model for legged mobile robots is proposed.For the predictability of the periodic motion of a legged robot,in the method,the images are sampled periodically,image blocks with clear texture are selected and the image details are enhanced to extract the feature points on the image.Then,the feature points of the blocks are extracted and by using the feature points of the blocks in the images,the feature points on the images are extracted.Finally,the points on the incident light through the normalised plane are selected as the template points;the relationship between the template points and the images is established through the wide-angle camera model,and the pixel coordinates of the template points in the images and the descriptors are calculated.Moreover,many experiments are conducted on the TUM datasets with a quadruped robot.The experimental results show that the trajectory error and translation error measured by the proposed method are reduced compared with the VINS-MONO,ORB-SLAM3 and Periodic SLAM systems. | Guangyu Fan Jiaxin Huang Dingyu Yang Lei Rao | 2022 | IET Cyber-Systems and Robotics2022，4，4： | 0 |
| 19 | Spacecraft damage infrared detection algorithm for hypervelocity impact based on double-layer multi-target segmentation显示文摘To detect spacecraft damage caused by hypervelocity impact,we propose an advanced spacecraft defect extraction algorithm based on infrared imaging detection.The Gaussian mixture model(GMM)is used to classify the temperature change characteristics in the sampled data of the infrared video stream and reconstruct the image to obtain the infrared reconstructed image(IRRI)reflecting the defect characteristics.The designed segmentation objective function is used to ensure the effectiveness of image segmentation results for noise removal and detail preservation,while taking into account the complexity of IRRI(that is,the required trade-offs are different).A multi-objective optimization algorithm is introduced to achieve balance between detail preservation and noise removal,and a multi-objective evolutionary algorithm based on decomposition(MOEA/D)is used for optimization to ensure damage segmentation accuracy.Experimental results verify the effectiveness of the proposed algorithm. | Xiao YANG Chun YIN Sara DADRAS Guangyu LEI Xutong TAN Gen QIU | 2022 | Frontiers of Information Technology & Electronic Engineering2022，23，4： | 0 |
