| 1 | An updated estimation of the risk of transmission of the novel coronavirus(2019-nCov)显示文摘The basic reproduction number of an infectious agent is the average number of infections one case can generate over the course of the infectious period,in a naïve,uninfected population.It is well-known that the estimation of this number may vary due to several methodological issues,including different assumptions and choice of parameters,utilized models,used datasets and estimation period.With the spreading of the novel coronavirus(2019-nCoV)infection,the reproduction number has been found to vary,reflecting the dynamics of transmission of the coronavirus outbreak as well as the case reporting rate.Due to significant variations in the control strategies,which have been changing over time,and thanks to the introduction of detection technologies that have been rapidly improved,enabling to shorten the time from infection/symptoms onset to diagnosis,leading to faster confirmation of the new coronavirus cases,our previous estimations on the transmission risk of the 2019-nCoV need to be revised.By using time-dependent contact and diagnose rates,we refit our previously proposed dynamics transmission model to the data available until January 29th,2020 and re-estimated the effective daily reproduction ratio that better quantifies the evolution of the interventions.We estimated when the effective daily reproduction ratio has fallen below 1 and when the epidemics will peak.Our updated findings suggest that the best measure is persistent and strict self-isolation.The epidemics will continue to grow,and can peak soon with the peak time depending highly on the public health interventions practically implemented. | Biao Tang Nicola Luigi Bragazzi Qian Li Sanyi Tang Yanni Xiao Jianhong Wu | 2020 | Infectious Disease Modelling2020,5,1: | 54 |
| 2 | 饲料中添加水解鱼蛋白对半滑舌鳎稚鱼生长及生理生化指标的影响显示文摘试验研究了饲料中添加不同水平(0%、20%、40%和60%)的水解鱼蛋白(Fish potein hdrolysate,FPH)对半滑舌鳎(Cynoglossus semilaevis Günther)稚鱼生长及生理生化指标的影响。28d饲养实验结束后,对试验鱼生长指标、鱼体消化酶活性、碱性磷酸酶(AKP)及肠道发育情况进行分析。结果显示:实验鱼的存活率为64.44%—78.88%,其中20%与40%添加组存活率显著高于其他两组(P<0.05);实验鱼的特定生长率(SGR)随饲料中FPH添加水平升高呈下降趋势,20%添加组特定生长率最高,显著高于其他3组(P<0.05),且60%添加组与对照组(FM)之间无显著差异(P>0.05);各试验组鱼体消化酶(脂肪酶、淀粉酶、胃蛋白酶和胰蛋白酶)的比活力在14d与28d时的强弱关系不一致。鱼体碱性磷酸酶比活力大小依次为:20%组>40%组>对照组>60%组,各组间差异均显著(P<0.05);半滑舌鳎肠道微绒毛长度和黏膜厚度均以20%添加组为最优,显著优于其他3组(P<0.05)。以上结果表明,在实验条件下,饲料中FPH的添加水平为20%时,能提高半滑舌鳎稚鱼的存活率及生长性能,并增强其对营养物质的吸收能力。 | 柳旭东 梁萌青 张利民 王际英 常青 王家林 Yannis Kotzamanis | 2010 | 水生生物学报2010,34,2: | 20 |
| 3 | Laboratory investigation on the properties of asphalt mixtures modified with double-adding admixtures and sensitivity analysis显示文摘In order to improve the high temperature stability and low temperature cracking resistance of asphalt mixtures,two varieties of admixtures(anti-rutting agent and lignin fiber) were selected and then combined.This is called double-mixture technology.A series of tests about pavement performance of base asphalt mixtures and asphalt mixtures with admixture of anti-rutting agent or lignin fiber were conducted.Meanwhile sensitivity analyses were used to study the influence of three factors(i.e.,asphalt grade,aggregate type and gradation) on the high and low temperature performance and water stability of said asphalt mixtures.Test results indicated that the dynamic stability,residual stability,TSR and low temperature failure strain of asphalt mixtures have increased significantly with the additions of 0.40% anti-rutting agent and 0.36% lignin fiber.These results show that the high and low temperature and water stabilities of asphalt mixtures improve obviously.This supports the beneficial comprehensive effect of the double admixture.The problem of improving the asphalt mixtures performance with a single admixture is solved,in addition to also improving other pavement performance.Based on the sensitivity analysis,the most influential factors of dynamic stability,low temperature failure strain and TSR are the gradation,followed by asphalt grade and aggregate type. | Zhen Fu Yanni Dang Bo Guo Yue Huang | 2016 | Journal of Traffic and Transportation Engineering(English Edition)2016,3,5: | 17 |
| 4 | 特高压直流换流变压器试验标准和要求的探讨(英文)显示文摘中国目前正在建设两个打破世界纪录的特高压直流输电工程,一是±800kV云南—广东直流输电工程,二是±800kV向家坝—上海直流输电工程。文章探讨了这两项直流输电工程的换流变压器在型式试验期间遇到的一些技术问题。该试验是按照客户基于相关的IEC标准提出的项目设备规范要求实施的,因此研究结果与相关的IEC标准及该试验的实际经验有关。基于这些研究结果,KEMA提出了对将来工程中换流变压器的试验要求的建议以及针对个别具体试验的改进措施。有一点要强调的,KEMA所推荐的变压器试验顺序值得遵循,因为在这一方面IEC标准是不明确的。 | Yanny Fu Peter Vaessen Wilco Rorijs Mark Louwerse | 2009 | 南方电网技术2009,3,3: | 16 |
| 5 | The impacts of conservation agriculture on crop yield in China depend on specific practices, crops and cropping regions显示文摘For smooth and wide application of conservation agriculture(CA), remaining uncertainties about its impacts on crop yield need to be reduced. Based on previous field experiments in China, a meta-analysis was performed to quantify the actual impacts of CA practices(NT: no/reduced-tillage only, CTSR: conventional tillage with straw retention, NTSR: NT with straw retention) on crop yields as compared to conventional tillage without straw retention(CT).Although CA practices increased crop yield by 4.6% on average, there were large variations in their impacts. For each CA practice, CTSR and NTSR significantly increased crop yield by 4.9%and 6.3%, respectively, compared to CT. However, no significant effect was found for NT. Among ecological areas, significant positive effects of CA practices were found in areas with an annual precipitation below 600 mm. Similar effects were found in areas with annual mean air temperature above 5 °C. For cropping regions, CA increased crop yield by 6.4% and 5.5%compared to CT in Northwest and South China, respectively, whereas no significant effects were found in the North China and Northeast China regions. Among crops, the positive effects of CA practices were significantly higher in maize(7.5%) and rice(4.1%) than in wheat(2.9%). NT likely decreased wheat yield. Our results indicate that there are great differences in the impacts of CA practices on crop yield, owing to regional variation in climate and crop types. CA will most likely increase maize yield but reduce wheat yield. It is strongly recommended to apply CA with crop straw retention in maize cropping areas and seasons with a warm and dry climate pattern. | Chengyan Zheng Yu Jiang Changqing Chen Yanni Sun Jinfei Feng Aixing Deng Zhenwei Song Weijian Zhang | 2014 | The Crop Journal2014,2,5: | 15 |
| 6 | A deep learning-enabled portable imaging flow cytometer for cost-effective, highthroughput, and label-free analysis of natural water samples显示文摘We report a deep learning-enabled field-portable and cost-effective imaging flow cytometer that automatically captures phase-contrast color images of the contents of a continuously flowing water sample at a throughput of 100 mL/h.The device is based on partially coherent lens-free holographic microscopy and acquires the diffraction patterns of flowing micro-objects inside a microfluidic channel.These holographic diffraction patterns are reconstructed in real time using a deep learning-based phase-recovery and image-reconstruction method to produce a color image of each micro-object without the use of external labeling.Motion blur is eliminated by simultaneously illuminating the sample with red,green,and blue light-emitting diodes that are pulsed.Operated by a laptop computer,this portable device measures 15.5 cm×15 cm×12.5 cm,weighs 1 kg,and compared to standard imaging flow cytometers,it provides extreme reductions of cost,size and weight while also providing a high volumetric throughput over a large object size range.We demonstrated the capabilities of this device by measuring ocean samples at the Los Angeles coastline and obtaining images of its micro-and nanoplankton composition.Furthermore,we measured the concentration of a potentially toxic alga(Pseudo-nitzschia)in six public beaches in Los Angeles and achieved good agreement with measurements conducted by the California Department of Public Health.The cost-effectiveness,compactness,and simplicity of this computational platform might lead to the creation of a network of imaging flow cytometers for largescale and continuous monitoring of the ocean microbiome,including its plankton composition. | Zoltán Gӧrӧcs Miu Tamamitsu Vittorio Bianco Patrick Wolf Shounak Roy Koyoshi Shindo Kyrollos Yanny Yichen Wu Hatice Ceylan Koydemir Yair Rivenson Aydogan Ozcan | 2018 | Light(Science & Applications)2018,7,1: | 14 |

| 8 | A novel four-way combining catalysts for simultaneous removal of exhaust pollutants from diesel engine显示文摘A novel four-way combining catalysts containing double layers was applied to simultaneously remove four kinds of exhaust pollutants(NOx,CO,HC and PM) emitted from diesel engine.The four-way catalysts were characterized using scanning electron microscope(SEM) and Ultraviolet visible diffuse reflectance spectroscopy(UV-Vis DRS).Their catalytic performances were evaluated by temperature-programmed reaction technology.The double layer catalysts could effectively remove the four main pollutants.The highest catalytic activity was given by the two-layered catalysts of La0.6K0.4CoO3/Al2O3 and W/HZSM-5.Under the simulated exhaust gases conditions,the peak temperature of the soot combustion was 421°C,the maximal conversion of NO to N2 was 74%,the temperature of the HC total conversion was 357°C,and the maximum conversion ratio of CO was 99%. | Jian Liu,Jie Xu,Zhen Zhao,Aijun Duan,Guiyuan Jiang,Yanni Jing State Key Laboratory of Heavy Oil Processing,China University of Petroleum,Beijing 102249,China. | 2010 | Journal of Environmental Sciences2010,22,7: | 11 |
| 9 | Application of bioactive hydrogels combined with dental pulp stem cells for the repair of large gap peripheral nerve injuries显示文摘Due to the limitations in autogenous nerve grafting or Schwann cell transplantation,large gap peripheral nerve injuries require a bridging strategy supported by nerve conduit.Cell based therapies provide a novel treatment for peripheral nerve injuries.In this study,we first experimented an optimal scaffold material synthesis protocol,from where we selected the 10%GFD formula(10%GelMA hydrogel,recombinant human basic fibroblast growth factor and dental pulp stem cells(DPSCs))to fill a cellulose/soy protein isolate composite membrane(CSM)tube to construct a third generation of nerve regeneration conduit,CSM-GFD.Then this CSM-GFD conduit was applied to repair a 15-mm long defect of sciatic nerve in a rat model.After 12 week post implant surgery,at histologic level,we found CSM-GFD conduit could regenerate nerve tissue like neuron and Schwann like nerve cells and myelinated nerve fibers.At physical level,CSM-GFD achieved functional recovery assessed by a sciatic functional index study.In both levels,CSM-GFD performed like what gold standard,the nerve autograft,could do.Further,we unveiled that almost all newly formed nerve tissue at defect site was originated from the direct differentiation of exogeneous DPSCs in CSM-GFD.In conclusion,we claimed that this third-generation nerve regeneration conduit,CSM-GFD,could be a promising tissue engineering approach to replace the conventional nerve autograft to treat the large gap defect in peripheral nerve injuries. | Lihua Luo Yan He Ling Jin Yanni Zhang Fernando P.Guastaldi Abdullkhaleg A.Albashari Fengting Hu Xiaoyan Wang Lei Wang Jian Xiao Lingli Li Jianming Wang Akon Higuchi Qingsong Ye | 2021 | Bioactive Materials2021,6,3: | 11 |
| 10 | LAMOST Experiment for Galactic Understanding and Exploration (LEGUE)——The survey's science plan显示文摘We describe the current plans for a spectroscopic survey of millions of stars in the Milky Way galaxy using the Guo Shou Jing Telescope (GSJT, formerly called the Large sky Area Multi-Object fiber Spectroscopic Telescope - LAMOST). The survey will obtain spectra for 2.5 million stars brighter than r < 19 during dark/grey time, and 5 million stars brighter than r < 17 or J < 16 on nights that are moonlit or have low transparency. The survey will begin in the fall of 2012, and will run for at least four years. The telescope's design constrains the optimal declination range for observations to 10 < δ < 50 , and site conditions lead to an emphasis on stars in the direction of the Galactic anticenter. The survey is divided into three parts with different target selection strategies: disk, anticenter, and spheroid. The resulting dataset will be used to study the merger history of the Milky Way, the substructure and evolution of the disks, the nature of the first generation of stars through identification of the lowest metallicity stars, and star formation through study of open clusters and OB associations. Detailed design of the LAMOST Experiment for Galactic Understanding and Exploration (LEGUE) survey will be completed in summer 2012, after a review of the results of the pilot survey. | Li-Cai Deng Heidi Jo Newberg Chao Liu Jeffrey L.

| 11 | VNF-FG design and VNF placement for 5G mobile networks显示文摘Network function virtualization(NFV) is envisioned as one of the critical technologies in 5thGeneration(5G) mobile networks. This paper investigates the virtual network function forwarding graph(VNFFG) design and virtual network function(VNF) placement for 5G mobile networks. We first propose a two-step method composed of flow designing and flow combining for generating VNF-FGs according to network service requests. For mapping VNFs in the generated VNF-FG to physical resources, we then modify the hybrid NFV environment with introducing more types of physical nodes and mapping modes for the sake of completeness and practicality, and formulate the VNF placement optimization problem for achieving lower bandwidth consumption and lower maximum link utilization simultaneously. To resolve this problem, four genetic algorithms are proposed on the basis of the frameworks of two existing algorithms(multiple objective genetic algorithm and improved non-dominated sorting genetic algorithm). Simulation results show that Greedy-NSGA-II achieves the best performance among our four algorithms. Compared with three non-genetic algorithms(random, backtracking mapping and service chains deployment with affiliation-aware), Greedy-NSGA-II reduces 97.04%, 87.76% and88.42% of the average total bandwidth consumption, respectively, and achieves only 13.81%, 25.04% and 25.41%of the average maximum link utilization, respectively. Moreover, using our VNF-FG design method and GreedyNSGA-II together can also reduce the total bandwidth consumption remarkably. | Jiuyue CAO Yan ZHANG Wei AN Xin CHEN Jiyan SUN Yanni HAN | 2017 | Science China(Information Sciences)2017,60,4: | 8 |

| 13 | High-resolution, in vivo multimodal photoacoustic microscopy, optical coherence tomography, and fluorescence microscopy imaging of rabbit retinal neovascularization显示文摘Photoacoustic microscopy(PAM)is an emerging imaging technology that can non-invasively visualize ocular structures in animal eyes.This report describes an integrated multimodality imaging system that combines PAM,optical coherence tomography(OCT),and fluorescence microscopy(FM)to evaluate angiogenesis in larger animal eyes.High-resolution in vivo imaging was performed in live rabbit eyes with vascular endothelial growth factor(VEGF)-induced retinal neovascularization(RNV).The results demonstrate that our multimodality imaging system can noninvasively visualize RNV in both albino and pigmented rabbits to determine retinal pathology using PAM and OCT and verify the leakage of neovascularization using FM and fluorescein dye.This work presents high-resolution visualization of angiogenesis in rabbits using a multimodality PAM,OCT,and FM system and may represent a major step toward the clinical translation of the technology. | Wei Zhang Yanxiu Li Van Phuc Nguyen Ziyi Huang Zhipeng Liu Xueding Wang Yannis M.Paulus | 2018 | Light(Science & Applications)2018,7,1: | 7 |

| 15 | Proteomic Analysis of Macrophages:A Potential Way to Identify Novel Proteins Associated with Activation of Macrophages for Tumor Cell Killing显示文摘One major mechanism through which macrophages effectively kill tumor cells requires cell to cell contact,indicating that certain molecules expressed on cell surface of activated macrophages may mediate the tumoricidal capability. Tumor necrosis factor (TNF) and nitric oxide (NO) are the two classical mediators of tumor cell death. However,evidence of discrepancy is accumulating indicating these known mediators do not appear to account for the broad and potent tumoricidal activity of macrophages. To obtain a full repertoire of tumoricidal activation-associated membrane proteins,we combined one-dimensional SDS-PAGE with capillary liquid chromatography-tandem mass spectrometry (LC-MS/MS). Using this technique,we identified 454 activated macrophage specifically expressed proteins with extremely high confidence,including most known activation markers of macrophages,such as NO synthase (iNOS),Ym1,cyclooxygenase,etc. Membrane bound TNF-α was also identified on activated macrophages. However,it was also detected on thioglycolate elicited macrophages,indicating this molecule may not play a key role in conjugation-dependent tumor cell killing. In contrast,although NO has not been assigned as an effector molecule of conjugation-dependent tumoricidal pathway,iNOS was identified from membrane fraction of activated macrophages,suggesting NO may be involved in conjugation-dependent tumoricidal mechanism,because iNOS association with plasma membrane is ideally suited to deliver NO directly into the contacted tumor cells. This research provides not only new insights into macrophage conjugation-dependent tumoricidal mechanisms,but also a valuable data set of macrophage activation associated membrane proteins,thus providing better understanding of the functional mechanisms of macrophages in anti-tumor and other biological processes. | Lingbing Zhang Haoxuan Zhu Yanni Lun Dongmei Yan Leyang Yu Bairong Du Xun Zhu | 2007 | Cellular & Molecular Immunology2007,4,5: | 7 |
| 16 | A novel xeno-free and feeder-cell-free system for human pluripotent stem cell culture显示文摘While human induced pluripotent stem cells(hiPSCs)have promising applications in regenerative medicine,most of the hiPSC lines available today are not suitable for clinical applications due to contamination with nonhuman materials,such as sialic acid,and potential pathogens from animal-product-containing cell culture systems.Although several xeno-free cell culture systems have been established recently,their use of human fibroblasts as feeders reduces the clinical potential of hiPSCs due to batch-to-batch variation in the feeders and time-consuming preparation processes.In this study,we have developed a xeno-free and feeder-cell-free human embryonic stem cell(hESC)/hiPSC culture system using human plasma and human placenta extracts.The system maintains the self-renewing capacity and pluripotency of hESCs for more than 40 passages.Human iPSCs were also derived from human dermal fibroblasts using this culture system by overexpressing three transcription factors—Oct4,Sox2 and Nanog.The culture system developed here is inexpensive and suitable for large scale production. | Qihui Wang Xiaoning Mou Henghua Cao Qingzhang Meng Yanni Ma Pengcheng Han Junjie Jiang Hao Zhang Yue Ma | 2012 | Protein & Cell2012,3,1: | 6 |
| 17 | Novel circular RNA expression profile of uveal melanoma revealed by microarray显示文摘Objective: The present study aimed to investigate circular RNA(circRNA) expression in uveal melanoma(UM).Methods: First,we used microarray to compare the expression profiles of circRNA in five UM samples and five normal uvea tissues.Next,bioinformatics analyses,including gene ontology(GO) analysis and pathway analysis,were applied to study these differentially expressed circRNAs to predict pathogenic pathways that may be involved.Quantitative real-time polymerase chain reaction(qRT-PCR) in 20 UM samples and 20 normal uvea samples was used to confirm the circRNA expression profiles obtained from the microarray data.Finally,we analyzed the interaction between validated circRNAs and their potential cancer-associated miRNA targets.Results: In total,50,579 circRNAs [fold change(FC) ≥2.0; P<0.05],including 20,654 up-regulated and 29,925 down-regulated circRNAs,were identified as differentially expressed between UM tissues and normal uvea tissues.We used qRT-PCR to verify seven dysregulated circRNAs indicated by the microarray data,including hsa_circ_0119873,hsa_circ_0128533,hsa_circ_0047924,hsa_circ_0103232,hsa-circRNA10628-6,hsa_circ_0032148 and hsa_circ_0133460,which may be promising candidates to study future molecular mechanisms.Conclusions: This study explored,for the first time,the abnormal expression of circRNAs in UM and described the expression profile of circRNAs,providing a new potential target for the mechanism of UM and future treatment of UM. | Xuan Yang Yang Li Yueming Liu Xiaolin Xu Yingzhi Wang Yanni Yan Wenjia Zhou Jingyan Yang Wenbin Wei | 2018 | Chinese Journal of Cancer Research2018,30,6: | 6 |
| 18 | Natural variations in flavonoids and triterpenoids of Cyclocarya paliurus leaves显示文摘Cyclocarya paliurus is widely distributed in subtropical areas of China.Secondary metabolites in the leaves,including flavonoids and triterpenoids,provide protection against diseases such as hyperlipidemia,diabetes,hypertension,and hypoimmunity.In this study,343 C.paliurus leaves were collected from 32 distinct populations covering most of the main distribution,to deduce the response of flavonoids and triterpenoids to seven environmental factors.Principal component analysis was performed using seven flavonoid and six triterpenoid compounds.The results show that altitude,latitude,and longitude significantly contributed to variations in total flavonoid and triterpenoid contents.In addition,the interaction of these metabolites was extensively correlated with environment changes,and therefore should be considered during selection and cultivation. | Caowen Sun Xulan Shang Haifen Ding Yanni Cao Shengzuo Fang | 2021 | Journal of Forestry Research2021,32,2: | 6 |
| 19 | Ozone Profile Retrieval from Satellite Observation Using High Spectral Resolution Infrared Sounding Instrument显示文摘This paper presents a preliminary result on the retrieval of atmospheric ozone profiles using an im- proved regression technique and utilizing the data from the Atmospheric InfraRed Sounder (AIRS), a hyper-spectral Instrument expected to be flown on the EOS-AQUA platform in 20D2. Simulated AIRS spectra were used to study the sensitivity of AIRS radiance on the tropospheric and stratospheric ozone changes, and to study the impact of various channel combinations on the ozone profile retrieval. Sensitivity study results indicate that the AIRS high resolution spectral channels between the wavenumber 650- 800 cm-1 provide very useful information to accurately retrieve tropospheric and stratospheric ozone pro- files Eigenvector decomposition of AIRS spectra indicate that no more than 100 eigenvectors are needed to retrieve very accurate ozone profiles. The accuracy of the retrieved atmospheric ozone profile from the pres- ent technique and utilizing the AIRS data was compared with the accuracy obtained from current Advanced TIROS Operational Vertical Sounder (ATOVS) data aboard National Oceanic and Atmospheric Admini- stration (NOAA) satellites As expected, a comparison of retrieval results confirms that the ozone profile re- trieved with the AIRS data is superior to that of | Yanni Qu, Mitchell D.

| 20 | Meta-analysis on integrative medicine for the treatment of malignant ascites: a comparative study显示文摘OBJECTIVE: To compare the efficacy of integrated Chinese and Western Medicine with that of only Western Medicine for the treatment of malignant ascites.METHODS: All randomized controlled trials(January 2004 to March 2013) from the China National Knowledge Infrastructure Database, Chinese Biomedical Literature Database, and Wanfang Database were searched with keywords. Meta-analysis was conducted by combining the odds ratios of the individual studies. Review Manager 5.0 was used for the analysis.RESULTS: One thousand one hundred and fifty-six patients from 19 randomized controlled trails were included. Of them, 630 patients were treated with integrated Chinese and Western Medicine(the integrative group), and 526 patients were treated with Western Medicine alone(the control group). The Meta-analysis showed that the total effective rate was 78.73% in the integrated group, and 59.13% in the control group. The effective percentage was sig-nificantly higher in the integrative group than that of the control group [OR = 2.85, 95% CI(2.16,3.74),P < 0.01].CONCLUSION: The short-term curative effect in the integrative group was better than that in the control group. Integrative medicine may be beneficial for malignant ascites. | Li Yuan Lou Yanni Deng Bo Jia Liqun | 2015 | Journal of Traditional Chinese Medicine2015,35,1: | 5 |
