| 1 | 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.

| 2 | 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 |
| 3 | 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 |

| 7 | Highly efficient removal of perfluorooctanoic acid from aqueous solution by H2O2-enhanced electrocoagulation-electroflotation technique显示文摘Electrocoagulation(EC)technique was used to investigate the removal performance of aqueous perfluorooctanoic acid(PFOA)with relatively high concentration as simulating the wastewater from organic fluorine industry.A comparison was done with the similar amount of coagulant between EC and chemical coagulation process.PFOA removal obtained was higher with EC process,especially for Fe anode.Several factors were studied to optimize the EC process.At the optimal operating parameters including 37.5 mA/cm^2 of current density,initial pH 3.77,and 180 rpm of mixing speed,93%of PFOA could be removed with 100 mg/L of initial concentration after 90-min electrolysis.Furthermore,the remove efficiency could be obviously improved by H2O2 intermittent addition,which removed more than 99%of PFOA within 40-min EC.It could be attributed to that H2O2 facilitated the oxidative transformation from ferrous to ferric ion.In addition,the adsorptive removal of aqueous PFOA on Fe flocs during EC was also verified by fourier transform infrared spectra. | Bo Yang Yanni Han Yunpan Deng Yingying Li Qiongfang Zhuo Jinhua Wu | 2016 | Emerging Contaminants2016，2，1： | 2 |
| 8 | An algorithm for preferential selection of spectroscopic targets in LEGUE显示文摘We describe a general target selection algorithm that is applicable to any survey in which the number of available candidates is much larger than the number of objects to be observed. This routine aims to achieve a balance between a smoothly- varying, well-understood selection function and the desire to preferentially select certain types of targets. Some target-selection examples are shown that illustrate different possibilities of emphasis functions. Although it is generally applicable, the algorithm was developed specifically for the LAMOST Experiment for Galactic Understanding and Exploration (LEGUE) survey that will be carried out using the Chinese Guo Shou Jing Telescope. In particular, this algorithm was designed for the portion of LEGUE targeting the Galactic halo, in which we attempt to balance a variety of science goals that require stars at fainter magnitudes than can be completely sampled by LAMOST. This algorithm has been implemented for the halo portion of the LAMOST pilot sur- vey, which began in October 2011. | Jeffrey L. Carlin Sebastien Lepine Heidi Jo Newberg Li-Cai Deng Timothy C.

| 10 | Adjustment of precipitation measurements using Total Rain weighing Sensor(TRwS)gauges in the cryospheric hydrometeorology observation(CHOICE)system of the Qilian Mountains,Northwest China显示文摘Precipitation is one of the most important indicators of climate data,but there are many errors in precipitation measurements due to the influence of climatic conditions,especially those of solid precipitation in alpine mountains and at high latitude areas.The measured amount of precipitation in those areas is frequently less than the actual amount of precipitation.To understand the impact of climatic conditions on precipitation measurements in the mountainous areas of Northwest China and the applicability of different gauges in alpine mountains,we established a cryospheric hydrometeorology observation(CHOICE)system in 2008 in the Qilian Mountains,which consists of six automated observation stations located between 2960 and 4800 m a.s.l.Total Rain weighing Sensor(TRwS)gauges tested in the World Meteorological Organization-Solid Precipitation Intercomparison Experiment(WMO-SPICE)were used at observation stations with the CHOICE system.To study the influence of climatic conditions on different types of precipitation measured by the TRwS gauges,we conducted an intercomparison experiment of precipitation at Hulu-1 station that was one of the stations in the CHOICE system.Moreover,we tested the application of transfer functions recommended by the WMO-SPICE at this station using the measurement data from a TRwS gauge from August 2016 to December 2020 and computed new coefficients for the same transfer functions that were more appropriate for the dataset from Hulu-1 station.The new coefficients were used to correct the precipitation measurements of other stations in the CHOICE system.Results showed that the new parameters fitted to the local dataset had better correction results than the original parameters.The environmental conditions of Hulu-1 station were very different from those of observation stations that provided datasets to create the transfer functions.Thus,root-mean-square error(RMSE)of solid and mixed precipitation corrected by the original parameters increased significantly by the averages of 0.135(353%)and 0.072 mm(111%),respectively.RMSE values of liquid,solid and mixed precipitation measurements corrected by the new parameters decreased by 6%,20% and 13%,respectively.In addition,the new parameters were suitable for correcting precipitation at other five stations in the CHOICE system.The relative precipitation(RP)increment of different types of precipitation increased with rising altitude.The average RP increment value of snowfall at six stations was the highest,reaching 7%,while that of rainfall was the lowest,covering 3%.Our results confirmed that the new parameters could be used to correct precipitation measurements of the CHOICE system. | ZHAO Yanni CHEN Rensheng HAN Chuntan WANG Lei | 2022 | Journal of Arid Land2022，14，3： | 1 |

| 13 | An Adaptive User Service Deployment Strategy for Mobile Edge Computing显示文摘Mobile edge computing(MEC) is a cloud server running at the edge of a mobile network, which can effectively reduce network communication delay. However, due to the numerous edge servers and devices in the MEC, there may be multiple servers and devices that can provide services to the same user simultaneously. This paper proposes a userside adaptive user service deployment algorithm ASD(Adaptive Service Deployment) based on reinforcement learning algorithms. Without relying on complex system information, it can master only a few tasks and users. In the case of attributes, perform effective service deployment decisions, analyze and redefine the key parameters of existing algorithms, and dynamically adjust strategies according to task types and available node types to optimize user experience delay. Experiments show that the ASD algorithm can implement user-side decision-making for service deployment. While effectively improving parameter settings in the traditional Multi-Armed Bandit algorithm,it can reduce user-perceived delay and enhance service quality compared with other strategies. | Gang Li Jingbo Miao Zihou Wang Yanni Han Hongyan Tan Yanwei Liu Kun Zhai | 2022 | China Communications2022，19，10： | 1 |
| 14 | A flexible approach for cyber threat hunting based on kernel audit records显示文摘Hunting the advanced threats hidden in the enterprise networks has always been a complex and difficult task.Due to the variety of attacking means,it is difficult for traditional security systems to detect threats.Most existing methods analyze log records,but the amount of log records generated every day is very large.How to find the information related to the attack events quickly and effectively from massive data streams is an important problem.Considering that the knowledge graph can be used for automatic relation calculation and complex relation analysis,and can get relatively fast feedback,our work proposes to construct the knowledge graph based on kernel audit records,which fully considers the global correlation among entities observed in audit logs.We design the construction and application process of knowledge graph,which can be applied to actual threat hunting activities.Then we explore different ways to use the constructed knowledge graph for hunting actual threats in detail.Finally,we implement a LAN-wide hunting system which is convenient and flexible for security analysts.Evaluations based on the adversarial engagement designed by DARPA prove that our platform can effectively hunt sophisticated threats,quickly restore the attack path or assess the impact of attack. | Fengyu Yang Yanni Han Ying Ding Qian Tan Zhen Xu | 2022 | Cybersecurity2022，5，3： | 0 |
| 15 | An Investigation Report on Production Conditions of Sugarcane in Guangxi in 2016显示文摘To predict and assess production conditions of sugarcane in Guangxi in 2016,by using methods of field survey and data collection,the seedling situation,breed structure,planting area,planting period,plant diseases and insect pests of sugarcane in six major sugarcane producing cities of Guangxi were surveyed. The results show that the overall situation of sugarcane seedlings in Guangxi in 2016 became slightly worse than that in 2015,but there were enough good sugarcane seedlings in 2016. The dead heart rate of sugarcane decreased in most sugarcane regions from 2015 to 2016,that is,the comprehensive control of borers gave initial results; the smut infection rate of sugarcane rose from 2015 to 2016 and tended to increase. The situation of decrease in the planting area of sugarcane in three consecutive years was controlled,and the planting area of sugarcane increased slightly from 2015 to 2016. Due to the construction of ' double high' bases,the breed variety of sugarcane in Guangxi was improved further in 2016. It is necessary to strengthen field management and conduct chemical weeding,prevention and control of borers and aphids in the later period in time. | Yuchi DENG Weizan WANG RonghuaZHANG Shiyun TANG Shanhai LIN Qiang LIANG Weixing DUAN Xiang LI Guoying LU Shijian HAN Youzong HUANG Yebin YANG Yanni HUANG Lunwang WANG | 2017 | Asian Agricultural Research2017，9，6： | 0 |
| 16 | VAECGAN:a generating framework for long-term prediction in multivariate time series显示文摘Long-term prediction is still a difficult problem in data mining.People usually use various kinds of methods of Recurrent Neural Network to predict.However,with the increase of the prediction step,the accuracy of prediction decreases rapidly.In order to improve the accuracy of long-term prediction,we propose a framework Variational Auto-Encoder Conditional Generative Adversarial Network(VAECGAN).Our model is divided into three parts.The first part is the encoder net,which can encode the exogenous sequence into latent space vectors and fully save the information carried by the exogenous sequence.The second part is the generator net which is responsible for generating prediction data.In the third part,the discriminator net is used to classify and feedback,adjust data generation and improve prediction accuracy.Finally,extensive empirical studies tested with five real-world datasets(NASDAQ,SML,Energy,EEG,KDDCUP)demonstrate the effectiveness and robustness of our proposed approach. | Xiang Yin Yanni Han Zhen Xu Jie Liu | 2021 | Cybersecurity2021，4，1： | 0 |
| 17 | Cytokine storm promoting T cell exhaustion in severe COVID-19 revealed by single cell sequencing data analysis显示文摘Background:Evidence has suggested that cytokine storms may be associated with T cell exhaustion(TEX)in COVID-19.However,the interaction mechanism between cytokine storms and TEX remains unclear.Methods:With the aim of dissecting the molecular relationship of cytokine storms and TEX through single-cell RNA sequencing data analysis,we identified 14 cell types from bronchoalveolar lavage fluid of COVID-19 patients and healthy people.We observed a novel subset of severely exhausted CD8 T cells(Exh T_CD8)that co-expressed multiple inhibitory receptors,and two macrophage subclasses that were the main source of cytokine storms in bronchoalveolar.Results:Correlation analysis between cytokine storm level and TEX level suggested that cytokine storms likely promoted TEX in severe COVID-19.Cell–cell communication analysis indicated that cytokines(e.g.CXCL10,CXCL11,CXCL2,CCL2,and CCL3)released by macrophages acted as ligands and significantly interacted with inhibitory receptors(e.g.CXCR3,DPP4,CCR1,CCR2,and CCR5)expressed by Exh T_CD8.These interactions formed the cytokine–receptor axes,which were also verified to be significantly correlated with cytokine storms and TEX in lung squamous cell carcinoma.Conclusions:Cytokine storms may promote TEX through cytokine-receptor axes and be associated with poor prognosis in COVID19.Blocking cytokine-receptor axes may reverse TEX.Our finding provides novel insights into TEX in COVID-19 and new clues for cytokine-targeted immunotherapy development. | Minglei Yang Chenghao Lin Yanni Wang Kang Chen Yutong Han Haiyue Zhang Weizhong Li | 2022 | Precision Clinical Medicine2022，5，2： | 0 |
| 18 | Determination of Boron in Refractories显示文摘Refractory materials have been widely used in high-temperature industries,in which the boron content has a great influence on the performance.To control the detection quality and satisfy the requirement of production and scientific research of refractories,conditional tests involving three methods for the boron determination(alkali titrimetry,inductively coupled plasma atomic emission spectrometry(ICP-AES),and curcumin absorption spectrophotometry)were carried out in this work.The affecting factors on the determination of boron were analyzed and discussed by performing the experiment.The results show that compared with curcumin absorption spectrophotometry,alkali titrimetry and ICP-AES have the advantages of simple operation,quick analysis and high precision(relative standard deviation<5%),which are more appropriate for boron determination in refractories. | WANG Yanni HAN Dan LEI Xiaoyu ZHANG Yajing | 2020 | China's Refractories2020，29，2： | 0 |
| 19 | Formation and Bioactivity of SrTiO_3 Nanotubes on Titanium by Modified Anodization and Hydrothermal Treatment显示文摘SrTiO_3 nanotube films with good adhesion strengths to Ti substrates were fabricated by using a hybrid approach with a modified anodization and a hydrothermal treatment(HT). The effect of Sr^(2+) concentration in HT solutions on the morphologies and phase components of the nanotubes were investigated,the SrTiO_3 nanotubes formation mechanism was explored, and the adhesion strengths, hydrophilicity and apatite-forming ability of the SrTiO_3 nanotubes were also evaluated. The results demonstrated that with increasing the incorporation of Sr^(2+) into the nanotubes, no obvious changes of the lengths and outer diameters of the nanotubes were observed, but the wall thickness and the crystallinity of SrTiO_3 in the nanotubes increased. The accumulation of Sr at the inner tube wall indicated that the reaction of Sr^(2+) with TiO_2 mainly occurred in the vicinity of internal surfaces of the closely arranged nanotubes. The formation of the SrTiO_3 nanotubes could be attributed to an in situ dissolution–recrystallization process.The Sr TiO_3 nanotubes exhibited good hydrophilicity and bioactivity, and the induced apatite preferred to nucleate on the nanotubes with higher crystallinity and Sr content, indicating a good bio-adaptability of the SrTiO_3 nanotubes for orthopedic application. | Yanni Zhang Yong Han Lan Zhang | 2016 | Journal of Materials Science & Technology2016，32，9： | 0 |
| 20 | A cost-effective ts CUT&Tag method for profiling transcription factor binding landscape显示文摘Knowledge of the transcription factor binding landscape(TFBL)is necessary to analyze gene regulatory networks for important agronomic traits.However,a low-cost and high-throughput in vivo chromatin profiling method is still lacking in plants.Here,we developed a transient and simplified cleavage under targets and tagmentation(tsCUT&Tag)that combines transient expression of transcription factor proteins in protoplasts with a simplified CUT&Tag without nucleus extraction.Our tsCUT&Tag method provided higher data quality and signal resolution with lower sequencing depth compared with traditional ChIP-seq.Furthermore,we developed a strategy combining tsCUT&Tag with machine learning,which has great potential for profiling the TFBL across plant development. | Leiming Wu Zi Luo Yanni Shi Yizhe Jiang Ruonan Li Xinxin Miao Fang Yang Qing Li Han Zhao Jiquan Xue Shutu Xu Tifu Zhang Lin Li | 2022 | Journal of Integrative Plant Biology2022，64，11： | 0 |
