| 1 | A new unequal-weighted triple-frequency first order ionosphere correction algorithm and its application in COMPASS显示文摘As the introduction of triple-frequency signals in GNSS,the multi-frequency ionosphere correction technology has been fast developing.References indicate that the triple-frequency second order ionosphere correction is worse than the dual-frequency first order ionosphere correction because of the larger noise amplification factor.On the assumption that the variances of three frequency pseudoranges were equal,other references presented the triple-frequency first order ionosphere correction,which proved worse or better than the dual-frequency first order correction in different situations.In practice,the PN code rate,carrier-to-noise ratio,parameters of DLL and multipath effect of each frequency are not the same,so three frequency pseudorange variances are unequal.Under this consideration,a new unequal-weighted triple-frequency first order ionosphere correction algorithm,which minimizes the variance of the pseudorange ionosphere-free combination,is proposed in this paper.It is found that conventional dual-frequency first-order correction algorithms and the equal-weighted triple-frequency first order correction algorithm are special cases of the new algorithm.A new pseudorange variance estimation method based on the three carrier combination is also introduced.Theoretical analysis shows that the new algorithm is optimal.The experiment with COMPASS G3 satellite observations demonstrates that the ionosphere-free pseudorange combination variance of the new algorithm is smaller than traditional multi-frequency correction algorithms. | WenXiang Liu WeiHua Mou FeiXue Wang | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，3： | 5 |
| 2 | Continuous and comprehensive atmospheric observations in Beijing:a station to understand the complex urban atmospheric environment显示文摘Due to profound impact on climate and human health,air quality has attracted attention from all levels of the civil society.The key step in the provision of required tools for the society to tackle the complex air quality problem is to characterize it in a comprehensive manner with a long-term perspective.Here,we describe a continuous and comprehensive observation station and its accompanying state-ofthe-art instrumentation that was established to investigate the complex urban atmospheric environment in a rapidly developing Chinese Megacity.The station,located in downtown Beijing,aims to study air quality by identifying the major atmospheric pollutants and key processes determining their formation and loss mechanisms.A few hundreds of parameters are continuously measured with the state-of-the-art instruments,including trace gas concentrations,aerosol particle size distributions,and mass concentrations,covering aerosol particle chemical composition from molecules to micrometer-sized aerosol particles.This produced long-term,comprehensive big data with around 1�10^(11)bytes per year.In this paper,we provide an overview on the facilities of the station,the instrumentation used,the workflow of continuous observations and examples of results from 2018 to 2019 and a basis for establishing a modern long-term,comprehensive atmospheric urban observation station in other megacities. | Yongchun Liu Chao Yan Zemin Feng Feixue Zheng Xiaolong Fan Yusheng Zhang Chang Li Ying Zhou Zhuohui Lin Yishou Guo Ying Zhang Li Ma Wenshuo Zhou Zhikun Liu Lubna Dada Kaspar Dallenbach Jenni Kontkanen Runlong Cai Tommy Chan Biwu Chu Wei Du Lei Yao Yonghong Wang Jing Cai Juha Kangasluoma Tom Kokkonen Joni Kujansuu Anton Rusanen Chenjuan Deng Yueyun Fu Rujing Yin Xiaoxiao Li Yiqun Lu Yiliang Liu Chaofan Lian Dongsen Yang Weigang Wang Maofa Ge Yuesi Wang Douglas R.Worsnop Heikki Junninen Hong He Veli-Matti Kerminen Jun Zheng Lin Wang Jingkun Jiang Tuukka Petaja Federico Bianchi Markku Kulmala | 2020 | Big Earth Data2020，4，3： | 3 |
| 3 | Expression of S100A10 gene and its regulation by sex hormones in mouse uterus显示文摘S100A10 belongs to the S100 calcium binding protein superfamily, and functions as one of the mediators of calcium-dependent signaling pathway. Recently, S100A10 gene was proved to be significantly up-regulated at the implantation site. In the present study, semi-quantitative reverse transcriptase-polymerase chain reaction and in situ hybridization are used to investigate the tissue-specificity of S100A10 expression and the expression pattern of S100A10 in the uteri during the estrous cycle and pregnancy. Meanwhile, the regulation of S100A10 expression by sex steroid hormones is studied in ovariectomized mice. The results show that S100A10 could be detected in various kinds of tissues, with relatively high expression in reproductive tracts including ovary, uterus, testis and epididymis.During pregnancy, the expression of S100A10 in the uteri is significantly up-regulated on the 4th day. The transcript is strongly detected in endometrial stromal cells and weakly in luminal epithelium cells at the implantation site, but almost not at the inter-implantation site.From gestational day 5 till labor, S100A10 mRNA maintains a certain level in both uteri and placentae. During the estrous cycle, expression of S100A10 is up-regulated in the uteri at proestrus and estrus. Estradiol significantly induces the expression of S100A10, while progesterone can abolish the effect of estradiol. The data suggests that S100A10 may be involved in preventing luminal epithelial cells from over-apoptosis, inducing proliferation and decidualization of stromal cells during implantation, and responding to reproductive stress triggered by copulation. | CHEN Zhiqiang LIU Jing LI Feixue SUN Xiaoyang ZHANG Huaiyun WANG Yanling | 2005 | Progress in Natural Science:Materials International2005，15，10： | 2 |

| 8 | A Layout Method of Space-Based Pseudolite System Based on GDOP Geometry显示文摘The pseudolite system can be used to provide positioning and timing service for users in a specific area.In order to provide better positioning and timing service,a good geometric configuration needs to be formed for the pseudolite system.For the problem of pseudolite system deployment,the average and mean square values of geometric dilution of precision(GDOP)are optimized in this paper for users in a target area.We proposed a space-based pseudolite deployment method based on GDOP geometry,starting from the minimum GDOP value for users in the central area.From the simulation results,it can be seen that,compared with the empirical method and the NSGA-II method,the method in this paper has the smallest average GDOP,a better robustness,and a higher positioning accuracy in the target area,through which a pseudolite deployment proposal can be quickly obtained. | YANG Xin WANG Feixue LIU Wenxiang XIAO Wei YE Xiaozhou | 2023 | Chinese Journal of Electronics2023，32，5： | 0 |

| 10 | Biological calcium phosphate nanorods for piezocatalytical extraction of U(VI)from water显示文摘The application of nanomaterials in energy and environmental fields has recently made great progress.As a key element in the nuclear industry,the discharge of uranium(U(VI))contained wastewater usually induces environmental issues and waste of resources.Although the catalytically generated H_(2)O_(2)by nanomaterials has recently shown application potential in extracting U(VI)from water,low-cost and highly efficient nanocatalysts are still urgently needed.In this work,a cheap and readily available piezocatalyst of calcium phosphate nanorods was successfully fabricated by calcining chicken bones.Under ultrasonication,H_(2)O_(2)was produced and used to extract U(VI)from water.It is worth noting that the yield of H_(2)O_(2)reached 179.7μmol·g^(−1)·h^(−1),and the extraction efficiency of U(VI)in water reached 97.16%(100 ppm)within 330 min.Through the capture and quantitative analysis of the active species,it is found that the generation of H_(2)O_(2)depends on the combination of soluble oxygen and piezoelectrons,which thus dominates the extraction of U(VI).This simple and powerful piezocatalytic strategy greatly reduces the cost of H_(2)O_(2)production for U(VI)extraction in water,and is of great significance for the treatment of U(VI)-containing wastewater. | Feixue Gao Zhe Wang Ming Fang Xiaoli Tan Shao Hui Xu Mao Liu Guang Tao Fei Li De Zhang | 2023 | Nano Research2023，16，11： | 0 |
| 11 | Liensinine alleviates septic heart injury by targeting inflammation,oxidative stress,apoptosis,and autophagy显示文摘Sepsis is one of the most commonly discussed worldwide health issues,with high rates of morbidity and mortality[1].Severe sepsis can trigger a systemic inflammatory response,which can result in organ failure and death in a short time.Of all organs,the heart is one of the most vulnerable target organs during sepsis[2].Previous research has revealed that sepsis-induced heart damage is often accompanied by uncontrolled inflammation,oxidant/antioxidant imbalance,excessive apoptosis,and autophagy. | Wei Zhang Tianling Wang Huizhen Chen Hui Fan Feixue Liu Xiao Zhang Haitao Yang Xueqing Li Zibo Dong Jingquan Dong | 2023 | Acta Biochimica et Biophysica Sinica2023，55，3： | 0 |
| 12 | Early rehabilitation and neuroprotective drug therapy outcomes in elderly patients with acute stroke显示文摘Sixty elderly patients, who suffered from acute stroke and were admitted within a 1-year period to the Department of Geriatrics in the First Affiliated Hospital of School of Medicine, Zhejiang University, China, underwent early rehabilitation in combination with neuroprotective drug therapy. Limb movement, cognitive functions and daily life self-care ability in elderly patients upon admission and discharge were assessed using the Hunt-Hess scale, functional independence measures and mini-mental state examination. The mean duration of hospital stay among the 60 patients was 35 days. Upon discharge, 42 (75%) of the patients exhibited cognitive impairment to varying degrees, and 25 (45%) of the 56 stroke patients who underwent rehabilitation evaluation attained independence in daily living activities, 11 (20%) required intermittent supervision, and 20 (36%) required 24-hour constant supervision during performance of these activities. Results demonstrated that early rehabilitation treatment in combination with neuroprotective therapy for acute stroke was effective. | Yue Chen Lufang Chen Yiqing Tao Feixue Zhou Chunlan Cui Shichao Liu | 2011 | Neural Regeneration Research2011，6，11： | 0 |
