| 1 | Accuracy Analysis of Low Altitude Photogrammetry with Wide-angle Camera显示文摘Firstly,the relationship between the accuracy of low altitude aerial photogrammetry and the field angle of camera is made by a quantitative analysis from the theory.The conclusion that the low altitude photogrammetry should use wide-angle camera as much as possible is done.Then,the limitation of the single lens camera to expand field angle and the combined wide-angle camera existing on the market not suitable for light load of low altitude UAV(Unmanned Aerial Vehicle)due to excessive weight are pointed out.The characteristics of combined wide-angle low altitude light camera with self-calibration and self-stabilization developed by the author are described,especially the principle of self-calibration for the combination of static error and dynamic error.Based on the practice of large scale mapping,a technical procedure in aerial photography by taking with wide-angle camera and large overlap simultaneously for improving the accuracy of low altitude photogrammetry is proposed.The typical engineering produced data is used to verity the above theoretical analysis.A technical route for increasing accuracy of low altitude photogrammetry with combined wide-angle camera is expounded. | Zongjian LIN Feifei XIE Guozhong SU | 2018 | Journal of Geodesy and Geoinformation Science2018，1，1： | 5 |

| 3 | 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 |

| 6 | Development and validation of InDel markers for identification of QTL underlying flowering time in soybean显示文摘Soybean [Glycine max(L.) Merrill] is a major plant source of protein and oil. An accurate and well-saturated molecular linkage map is a prerequisite for forward genetic studies of gene function and for modern breeding for many useful agronomic traits. Next-generation sequence data available in public databases provides valuable information and offers new insights for rapid and efficient development of molecular markers. In this study, we attempted to show the feasibility and facility of using genomic resequencing data as raw material for identifying putative In Del markers. First, we identified 17,613 In Del sites among 56 soybean accessions and obtained 12,619 primer pairs. Second, we constructed a genetic map with a random subset of 2841 primer pairs and aligned 300 polymorphic markers with the 20 consensus linkage groups(LG). The total genetic distance was 2347.3 c M and the number of mapped markers per LG ranged from 10 to 23 with an average of 15 markers. The largest and smallest genetic distances between adjacent markers were 52.3 c M and 0.1 cM, respectively. Finally, we validated the genetic map constructed by newly developed In Del markers by QTL analysis of days to flowering(DTF) under different environments. One major QTL(qDTF4) and four minor QTL(qDTF20, qDTF13, qDTF12,and q DTF11) on 5 LGs were detected. These results demonstrate the utility of the In Del markers developed in this work for map-based cloning and molecular breeding in soybean. | Jialin Wang Lingping Kong Kanchao Yu Fengge Zhang Xinyi Shi Yanping Wang Haiyang Nan Xiaohui Zhao Sijia Lu Dong Cao Xiaoming Li Chao Fang Feifei Wang Tong Su Shichen Li Xiaohui Yuan Baohui Liu Fanjiang Kong | 2018 | The Crop Journal2018，6，2： | 1 |
| 7 | Characteristics of Liver Functions in Patients With COVID-19 and Construction of a Prognostic Evaluation Decision Model Based on Liver Functions显示文摘A number of studies have suggested that coronavirus disease 2019(COVID-19)can cause liver damage.However,clinical features and outcome of COVID-19 in patients with liver injury remain to be further investigated.In this study,the clinical data of 265 COVID-19 patients admitted to seven tertiary hospitals were collected.Based on a threshold for transaminase or total bilirubin levels at two times the normal upper limit,patients were divided into mild or moderate/severe liver injury groups.Among the 265 patients,183 patients showed liver injury within 48 hours of admission.Aspartate aminotransferase levels were predominantly elevated in the liver injury group,but albumin levels were reduced.Moreover,fibrinogen and D-dimer were significantly increased.Furthermore,68%of the patients with moderate/severe liver injury had one or more underlying diseases.Almost half of these patients developed acute respiratory distress syndrome(44%)and secondary infections(46%).These patients showed increased interleukin-6 and interleukin-10 levels and a decrease in PaO2 and the oxygenation index.In addition,levels of alanine aminotransferase,aspartate aminotransferase,and albumin were correlated with the oxygenation index,D-dimer and lymphocyte counts.Furthermore,a novel prognostic assessment model based on liver function was established,which accuracy reached 88%and was able to accurately assess the prognosis of COVID-19 patients. | Tongtong Pan Dazhi Chen Chenwei Pan Yi Kang Junping Liu Feifei Su Liang Hong Huili Li Hui Zhao Zhuo Lin Xiaodong Wang Hongwei Lin Qianjing Du Chao Cai Yongping Chen | 2020 | Infectious Microbes & Diseases2020，2，4： | 1 |
| 8 | Phenol degradation in waters with high iodide level by layered double hydroxide-peroxodisulfate:Pathways and products显示文摘Recently, layered double hydroxide-peroxodisulfate(LDH-PDS) as an advanced oxidation system can effectively remove organics by the pathway of free radical. However, little has been known if there is a potential risk regarding the formation of high toxic iodine byproducts through another pathway when LDH-PDS is used in high iodide waters at coastal areas.Therefore, this study investigated phenol degradation pathways and transformation products to evaluate both removal mechanism and potential risk by LDH-PDS in high iodide waters. The results showed that in LDH-PDS system, with the degradation of PDS, phenol degraded till below detection limit in 1 hr in the presence of iodide, while PDS and phenol were hardly degraded in the absence of iodide, indicating iodide accelerated the transformation of PDS and the degradation of phenol. What is more, it reached the highest phenol removal efficiency under the condition of 100 mg/L LDH, 0.1 mmol/L PDS and 1.0 mmol/L iodide. In LDH-PDS system, iodide was rapidly oxidized by the highly active interlayer PDS, resulting in the formation of reactive iodine including hypoiodic acid, iodine and triiodide instead of free radicals, which contributed rapid degradation of phenol. However, unfortunately toxic iodophenols were detected. Specifically, 2-iodophenol and 4-iodophenol were formed firstly,afterwards 2,4-diiodophenol and 2,6-diiodophenol were produced, and finally iodophenols and diiodophenols gradually decreased and 2,4,6-Triiodophenol were produced. These results indicated that LDH-PDS should avoid to use in high iodide waters to prevent toxic iodine byproduct formation although iodide can accelerate phenol degradation. | Qingqing Su Peiyue Gao Ning Li Feifei Wang Xin Huang | 2022 | Journal of Environmental Sciences2022，34，6： | 0 |
| 9 | One droplet reaction for synthesis of multi-sized nanoparticles显示文摘Reaction kinetics of nanoparticles can be controlled by tuning the Peclet number(Pe)as it is an essential parameter in synthesis of multi-sized nanoparticles.Herein,we propose to implement a self-driven multi-dimension microchannels reactor(MMR)for the one droplet synthesis of multi-sized nanoparticles.By carefully controlling the Pe at the gas-liquid interface,the newly formed seed crystals selectively accumulate and grow to a specific size.By the combination of microchannels of different widths and lengths,one droplet reaction in the same apparatus achieves the synchronous synthesis of diverse nanoparticles.MMR enables precise control of nanoparticle diameter at 5 nm precision in the range of 10-110 nm.The use of MMR can be extended to the synthesis of uniform Ag,Au,Pt,and Pd nanoparticles,opening towards the production and engineering of nanostructured materials.This approach gives the chance to regulate the accumulation probability for precise synthesis of nanoparticles with different diameters. | Bingda Chen Feifei Qin Meng Su Daixi Xie Zeying Zhang Qi Pan Huadong Wang Xu Yang Sisi Chen Jingwei Huang Dominique Derome Jan Carmeliet Yanlin Song | 2023 | Nano Research2023，16，4： | 0 |
| 10 | Research on the structural features and influencing factors of the scientific exchange network of countries along 'the belt and road'显示文摘'The Belt and Road' is an initiative proposed by China in recent years to cooperate and develop to build a community with a shared future for mankind. Analyzing the academic exchanges of countries along the 'The Belt and Road' can provide a quantitative reference for future international scientific and technological exchanges, collaborative innovation development and related research. We carry out matrix construction and network structure analysis on the citation and cooperation of highly cited papers among countries along the 'Belt and Road' included in China from 2013 to 2018 included in Web of Science Core Collection, and explore the current status of scientific exchanges in countries along 'the Belt and Road'. The Quadratic Assignment Procedure analysis method verifies the influence of five variables, including geographic proximity, differences in economic levels, scientific productivity, similarity of research content,and economic and trade cooperation, on scientific exchange networks. The research results show that the countries along the 'the Belt and Road' have relatively close academic exchanges;Geographical proximity, similarity of research content, differences in economic level between countries, and differences in scientific productivity are significantly correlated with each other;the similarity of scientific and technological level and research content and the closeness of economic and trade cooperation have a positive effect on scientific exchanges as a whole. | Feifei Wang Wenfei Han Xinyue Yi Ziyao Su | 2022 | Data Science and Informetrics2022，2，2： | 0 |

| 13 | Construction and usage of terminology services for information retrieval显示文摘In information retrieval, thesauri have increasingly become vital as an aid to effective retrieval. In the networked environment, terminology services become an ideal way to employ thesauri in application systems. However, most of existing projects or systems focused mainly on the construction of terminology services and seldom gave attention to their usage. The overall purpose of this study is to investigate the construction of terminology services and their usage. Firstly, taking Chinese Thesaurus as a source vocabulary, a system was built with the use of REST architecture and Semantic Web technologies. After the construction of terminology services, this study used the above mentioned six terminology services to investigate the usage of terminology services in information retrieval systems based on the embedded client. Taking the get Synonym service as an example, the usefulness of terminology services was tested with an experiment of 30 user queries to the library OPAC system and Baidu Search Engine. OPAC’s experiment results showed that the average recall increases 26.7% while the average precision decreases 4.6%. Baidu’s experiment results showed that the P@5 precision increases 16%. Four usage modes were designed, including multiple choice for query expansion, single choice for query replacement, hybrid of query expansion and replacement, and automatic query expansion. To evaluate their usability, a user testing was carried out in the library OPAC system and Baidu Search Engine with 24 human subjects based on four usability criteria(effectiveness, efficiency, user satisfaction and learnability). The evaluation results showed that multiple choice for query expansion was the best usage mode which is more effective, easier to use, easier to learn, and has higher user satisfaction. | OU Shiyan TANG Zhengui SU Feifei | 2016 | Journal of Library Science in China2016，，1： | 0 |
| 14 | Recognition for avian influenza virus proteins based on support vector machine and linear discriminant analysis显示文摘Total 200 properties related to structural characteristics were employed to represent structures of 400 HA coded proteins of influenza virus as training samples. Some recognition models for HA proteins of avian influenza virus (AIV) were developed using support vector machine (SVM) and linear discriminant analysis (LDA). The results obtained from LDA are as follows: the identification accuracy (Ria) for training samples is 99.8% and Ria by leave one out cross validation is 99.5%. Both Ria of 99.8% for training samples and Ria of 99.3% by leave one out cross validation are obtained using SVM model, respectively. External 200 HA proteins of influenza virus were used to validate the external predictive power of the resulting model. The external Ria for them is 95.5% by LDA and 96.5% by SVM, respectively, which shows that HA proteins of AIVs are preferably recognized by SVM and LDA, and the performances by SVM are superior to those by LDA. | LIANG GuiZhao CHEN ZeCong YANG ShanBin MEI Hu ZHOU Yuan YANG Li ZHOU Peng YANG ShengXi SHU Mao LIAO ChunYang WU ShiRong LI GenRong HE Liu GAO JianKun Gan MengYu LI DeJing CHEN GuoPing WANG GuiXue LONG Sha JING JuHua ZHENG XiaoLin ZENG Hui ZHANG QiaoXia ZHANG MengJun YANG Qi TIAN FeiFei TONG JianBo WANG JiaoNa LIU YongHong LI Bo QIU LiangJia CAI ShaoXi ZHAO Na YANG Yan SU XiaLi SONG Jian CHEN MeiXia ZHANG XueJiao SUN JiaYing LI JingWei CHEN GuoHua CHEN Gang DENG Jie PENG ChuanYou ZHU WanPing XU LuoNan WU YuQuan LIAO LiMin LI Zhi LI Jun LU DaJun SU QinLiang HUANG ZhengHu ZHOU Ping LI ZhiLiang | 2008 | Science China Chemistry2008，51，2： | 0 |
| 15 | Identifying human-induced influence on microbial community:A comparative study in the effluent-receiving areas in Hangzhou Bay显示文摘Microbial community structure is afiected by both natural processes and human activities.In coastal area,anthropegenetic activity can usually lead to the discharge of the effluent from wastewater treatment plant(WWTP)to sea,and thus the water quality chronically turns worse and marine ecosystem becomes unhealthy.Microorganisms play key roles in pollutants degradation and ecological restoration;however,there are few studies about how the WWTP effluent disposal influences coastal microbial communities.In this study,sediment samples were collected from two WWTP effluentreceiving areas(abbreviated as JX and SY)in Hangzhou Bay.First,based on the high-throughput sequencing of 16S rRNA gene,microbial community structure was analyzed.Secondly,several statistical analyses were conducted to reveal the microbial community characteristics in response to the effluent disposal.Using PCoA,the significant difference of in microbial community structure was determined between JX and SY;using RDA,water COD and temperature,and sediment available phosphate and ammonia nitrogen were identified as the key environmental factors for the community difference;using LDA effect size analysis,the most distinctive microbes were found and their correlations with environmental factors were investigated;and according to detrended beta-nearesttaxon-index,the sediment microbial communities were found to follow'niche theory'.An interesting and important finding was that in SY that received more and toxic COD,many distinctive microbes were related to the groups that were capable of degrading toxic organic pollutants.This study provides a clear illustration of eco-environmental deterioration under the long-term human pressure from the view of microbial ecology. | Yuhan Zheng Zhiguo Su Tianjiao Dai Feifei Li Bei Huang Qinglin Mu Chuanping Feng Donghui Wen | 2019 | Frontiers of Environmental Science & Engineering2019，13，6： | 0 |
| 16 | Diversity and independent evolutionary profiling of rodent-borne viruses in Hainan,a tropical island of China显示文摘The risk of emerging infectious diseases(EID)is increasing globally.More than 60%of EIDs worldwide are caused by animal-borne pathogens.This study aimed to characterize the virome,analyze the phylogenetic evolution,and determine the diversity of rodent-borne viruses in Hainan Province,China.We collected 682 anal and throat samples from rodents,combined them into 28 pools according to their species and location,and processed them for next-generation sequencing and bioinformatics analysis.The diverse viral contigs closely related to mammals were assigned to 22 viral families.Molecular clues of the important rodent-borne viruses were further identified by polymerase chain reaction for phylogenetic analysis and annotation of genetic characteristics such as arenavirus,coronavirus,astrovirus,pestivirus,parvovirus,and papillomavirus.We identified pestivirus and bocavirus in Leopoldoms edwardsi from Huangjinjiaoling,and bocavirus in Rattus andamanensis from the national nature reserves of Bangxi with low amino acid identity to known pathogens are proposed as the novel species,and their rodent hosts have not been previously reported to carry these viruses.These results expand our knowledge of viral classification and host range and suggest that there are highly diverse,undiscovered viruses that have evolved independently in their unique wildlife hosts in inaccessible areas. | Youyou Li Chuanning Tang Yun Zhang Zihan Li Gaoyu Wang Ruoyan Peng Yi Huang Xiaoyuan Hu Henan Xin Boxuan Feng Xuefang Cao Yongpeng He Tonglei Guo Yijun He Haoxiang Su Xiuji Cui Lina Niu Zhiqiang Wu Jian Yang Fan Yang Gang Lu Lei Gao Qi Jin Meifang Xiao Feifei Yin Jiang Du | 2023 | Virologica Sinica2023，38，5： | 0 |
| 17 | Deposition processes of gas hydrate-bearing sediments in the inter-canyon area of Shenhu Area in the northern South China Sea显示文摘The Shenhu Submarine Canyon Group on the northern slope of the South China Sea consists of 17 slope-confined canyons,providing a good example for investigating their hosting sediments.Three drilling sites,including W07,W18,and W19,have proven the occurrence of gas hydrate reservoirs in the inter-canyon area between canyons C11 and C12.Whereas,variations of the geomorphology and seismic facies analyzed by high-resolution 3D seismic data indicate that the gas hydrate-bearing sediments may form in different sedimentary processes.In the upper segment,a set of small-scale channels with obvious topographic lows can be identified,revealing fine-grained turbidites supplied from the shelf region during a very short-term sea-level lowstand.In the middle part,gas hydrate units at Site W07 showing mounded or undulation external configuration are interpreted as sliding sedimentary features,and those features caused by gravity destabilization were the main formative mechanism of gas hydrate-bearing sediments that were sourced from the upper segments.In contrast,for the canyon transition zone of lower segments between C11-C12 inter-canyon and C12 intra-canyon areas,where W18 and W19 sites are located,the gas hydratebearing sediments are deposited in the channelized feature in the middle to lower segment and slide erosive surface.Gas hydrate-bearing sediments of the lower segment were migrated through channelized features interconnecting with the middle to lower slope by gravity-driven flows.The majority of deposits tended to be furtherly moved by lateral migration via erosive surface created by sediment failed to intra-canyon area.The conclusion of this study may help better understand the interaction between the formation mechanism of gas hydrate-bearing sediments and the geomorphologic effects of inter-canyon areas. | Zhixuan LIN Ming SU Haiteng ZHUO Pibo SU Jinqiang LIANG Feifei WANG Chengzhi YANG Kunwen LUO | 2023 | Journal of Oceanology and Limnology2023，41，2： | 0 |
