| 1 | Digital zenith telescope prototype of China显示文摘Classical optical astronomy measures the direction of the local plumb line on the stellar background,and is influenced by variations of the earth gravity field.Therefore,classical optical astrometry can be used to measure and study variations of plumb line.This endows classical optical astrometric technologies special significance for the interdisciplinary researches of astronomy and geoscience,and makes them irreplaceable by technologies like very long baseline interferometry,satellite laser ranging.However,classical astrometric instruments have a major drawback of low efficiency,such as the low automaticity,more operating observers,and even operative error which makes it very difficult to reduce the random observation error in some visual instruments.To overcome this drawback,we have successfully developed the digital zenith telescope prototype(DZT-1)with the aperture of200 mm,using charge coupled device and other advanced technologies and new equipments.As proved by test observations,DZT-1 can observe thousands of stars over one night,which significantly reduces the random observation error and increases the observation accuracy.In addition,DZT-1 has a high degree of automation,even allowing unattended observation by remote control.Besides,DZT-1 has a small-size and is easy to move,making it convenient for mobile measurement of the deflection of the vertical.In summary,DZT can be widely used in the geoscience and astronomy fields. | Lili Tian Jinyun Guo Yanben Han Xiushan Lu Weidong Liu Zheng Wang Bo Wang Zhiqiang Yin Hongqi Wang | 2014 | Chinese Science Bulletin2014，59，17： | 4 |
| 2 | BURST-LDA: A NEW TOPIC MODEL FOR DETECTING BURSTY TOPICS FROM STREAM TEXT显示文摘Topic models such as Latent Dirichlet Allocation(LDA) have been successfully applied to many text mining tasks for extracting topics embedded in corpora. However, existing topic models generally cannot discover bursty topics that experience a sudden increase during a period of time. In this paper, we propose a new topic model named Burst-LDA, which simultaneously discovers topics and reveals their burstiness through explicitly modeling each topic's burst states with a first order Markov chain and using the chain to generate the topic proportion of documents in a Logistic Normal fashion. A Gibbs sampling algorithm is developed for the posterior inference of the proposed model. Experimental results on a news data set show our model can efficiently discover bursty topics, outperforming the state-of-the-art method. | Qi Xiang Huang Yu Chen Ziyan Liu Xiaoyan Tian Jing Huang Tinglei Wang Hongqi | 2014 | Journal of Electronics(China)2014，31，6： | 3 |

| 4 | Image and data processing of digital zenith telescope(DZT-1) of China显示文摘The first digital zenith telescope prototype(DZT-1)of China was successfully developed by National Astronomical Observatories,Chinese Academy of Sciences and Shandong University of Science and Technology at the end of 2011.Compared with classical astrometric telescopes,DZT-1 has features of small size,high automation,and high accuracy.It can be used to do classical astrometric observations as well as measurement of plumb line variation and deflection of the vertical.So DZT-1 plays a significant role in astronomy and geoscience.Although the measurement principle and method of DZT-1 are somewhat similar to classical photographic zenith tube,there are still many differences.The present paper introduces the principle,method,and procedure for processing DZT-1 star image and data,as well as the application software for astronomical latitude and longitude calculation using DZT-1 observations.The test observations and the observation results are also presented.According to the test observation results,the standard deviation of single observation is about 0.200–0.300,and 0.0700–0.0800in term of a group observations.In conclusion,the data processing software fulfills DZT-1’s demand for data processing,guaranteeing the automation and high accuracy for DZT-1. | Bo Wang Lili Tian Zheng Wang Zhiqiang Yin Weidong Liu Qiyuan Qiao Hongqi Wang Yanben Han | 2014 | Chinese Science Bulletin2014，59，17： | 2 |
| 5 | Nitrogen-doped Carbon Nanospheres-Modified Graphitic Carbon Nitride with Outstanding Photocatalytic Activity显示文摘Metals and metal oxides are widely used as photo/electro-catalysts for environmental remediation.However,there are many issues related to these metal-based catalysts for practical applications,such as high cost and detrimental environmental impact due to metal leaching.Carbon-based catalysts have the potential to overcome these limitations.In this study,monodisperse nitrogen-doped carbon nanospheres(NCs)were synthesized and loaded onto graphitic carbon nitride(g-C3N4,GCN)via a facile hydrothermal method for photocatalytic removal of sulfachloropyridazine(SCP).The prepared metal-free GCN-NC exhibited remarkably enhanced efficiency in SCP degradation.The nitrogen content in NC critically influences the physicochemical properties and performances of the resultant hybrids.The optimum nitrogen doping concentration was identified at 6.0 wt%.The SCP removal rates can be improved by a factor of 4.7 and 3.2,under UV and visible lights,by the GCN-NC composite due to the enhanced charge mobility and visible light harvesting.The mechanism of the improved photocatalytic performance and band structure alternation were further investigated by density functional theory(DFT)calculations.The DFT results confirm the high capability of the GCN-NC hybrids to activate the electron–hole pairs by reducing the band gap energy and efficiently separating electron/hole pairs.Superoxide and hydroxyl radicals are subsequently produced,leading to the efficient SCP removal. | Qiaoran Liu Hao Tian Zhenghua Dai Hongqi Sun Jian Liu Zhimin Ao Shaobin Wang Chen Han Shaomin Liu | 2020 | Nano-Micro Letters2020，12，2： | 2 |

| 13 | Identification of Glutaminyl Cyclase isoenzyme isoQC as a regulator of SIRPα-CD47 axis显示文摘Dear Editor,Cancer cells often upregulate the expression of ligands for the inhibitory immune checkpoints receptor to escape anti-tumor immunity1. Targeting inhibitory immune checkpoints has become one of the most promising anticancer therapeutic inventions. Infiltration of myeloid cells, especially phagocytic cells, to tumors is often associated with chemotherapy resistance and progression of various cancer types. Phagocytosis of cancer cells is the major mechanism for these myeloid cells-mediated antitumor activity. However, many types of cancer cells express high level of ‘don’t eat me’ signals on the cell surface to escape the phagocytic cells-mediated antitumor immunity. | Zhiqiang Wu Linjun Weng Tengbo Zhang Hongling Tian Lan Fang Hongqi Teng Wen Zhang Jing Gao Yun Hao Yaxu Li Hu Zhou Ping Wang | 2019 | Cell Research2019，29，6： | 1 |
