| 1 | The wide-area difference system for the regional satellite navigation system of COMPASS显示文摘The regional satellite navigation system of COMPASS (Phase I) provides both open services and authorized services. Authorized services offer differential corrections and integrity information to users to support higher positioning, navigation and timing precision. Experimenting with real data, positioning accuracy is estimated with a 3GEO/4IGSO COMPASS constellation. The results show that with dual-frequency and single-frequency pseudo-range measurements, the positioning errors are respectively 8 and 10 m (RMS) for open service users, while for authorized users, the errors are 4 and 5 m (RMS), respectively. The COMPASS constellation geometry may cause large error to occur in the height component by 7-9 m for dualor single-frequency users, which can be effectively reduced with the differential corrections supplied by the authorized services. Multipath errors are identified and corrected for COMPASS, resulting in 25% positioning accuracy improvement for dual-frequency users and 10% improvement for single-frequency users. | CAO YueLing HU XiaoGong WU Bin ZHOU ShanShi LIU Li SU RanRan CHANG ZhiQiao HE Feng ZHOU JianHua | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，7： | 21 |
| 2 | Gene expression signatures for phlegm-dampness constitution of Chinese Medicine显示文摘Dear Editor,The term'individualized medicine'was first used in Biochemistry Individuality in 1956 by Williams(Williams et al.,1956).With the emergence of the post-genome era in the21st century,individualized precision medicine has attracted increasing attention.In traditional Chinese medicine(TCM),there is also concept of individualized medicine,which is known as the Chinese constitutional theory,proposed in the1970s(Wang,2012).According to this theory,the | Lingru Li Juan Feng Haiqiang Yao Lan Xie Yu Chen Lingling Yang Shujuan Hou Shipeng Zhao Ranran Sun Yanling Wu Tongtong Bai Yingshuai Li Ruoxi Yu Ji Wang Qi Wang | 2017 | Science China(Life Sciences)2017，60，1： | 13 |
| 3 | Analysis of RDSS positioning accuracy based on RNSS wide area differential technique显示文摘The BeiDou Navigation Satellite System(BDS) provides Radio Navigation Service System(RNSS) as well as Radio Determination Service System(RDSS).RDSS users can obtain positioning by responding the Master Control Center(MCC) inquiries to signal transmitted via GEO satellite transponder.The positioning result can be calculated with elevation constraint by MCC.The primary error sources affecting the RDSS positioning accuracy are the RDSS signal transceiver delay,atmospheric trans-mission delay and GEO satellite position error.During GEO orbit maneuver,poor orbit forecast accuracy significantly impacts RDSS services.A real-time 3-D orbital correction method based on wide-area differential technique is raised to correct the orbital error.Results from the observation shows that the method can successfully improve positioning precision during orbital maneuver,independent from the RDSS reference station.This improvement can reach 50% in maximum.Accurate calibration of the RDSS signal transceiver delay precision and digital elevation map may have a critical role in high precise RDSS positioning services. | XING Nan SU RanRan ZHOU JianHua HU XiaoGong GONG XiuQiang LIU Li HE Feng GUO Rui REN Hui HU GuangMing ZHANG Lei | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，10： | 6 |

| 5 | New insights into the associations among feed efficiency, metabolizable efficiency traits and related QTL regions in broiler chickens显示文摘Background: Improving the feed efficiency would increase profitability for producers while also reducing the environmental footprint of livestock production. This study was conducted to investigate the relationships among feed efficiency traits and metabolizable efficiency traits in 180 male broilers. Significant loci and genes affecting the metabolizable efficiency traits were explored with an imputation-based genome-wide association study. The traits measured or calculated comprised three growth traits, five feed efficiency related traits, and nine metabolizable efficiency traits.Results: The residual feed intake(RFI) showed moderate to high and positive phenotypic correlations with eight other traits measured, including average daily feed intake(ADFI), dry excreta weight(DEW), gross energy excretion(GEE), crude protein excretion(CPE), metabolizable dry matter(MDM), nitrogen corrected apparent metabolizable energy(AMEn), abdominal fat weight(Ab F), and percentage of abdominal fat(Ab P). Greater correlations were observed between growth traits and the feed conversion ratio(FCR) than RFI. In addition, the RFI, FCR, ADFI, DEW,GEE, CPE, MDM, AMEn, Ab F, and Ab P were lower in low-RFI birds than high-RFI birds(P < 0.01 or P < 0.05), whereas the coefficients of MDM and MCP of low-RFI birds were greater than those of high-RFI birds(P < 0.01). Five narrow QTLs for metabolizable efficiency traits were detected, including one 82.46-kb region for DEW and GEE on Gallus gallus chromosome(GGA) 26, one 120.13-kb region for MDM and AMEn on GGA1, one 691.25-kb region for the coefficients of MDM and AMEn on GGA5, one region for the coefficients of MDM and MCP on GGA2(103.45–103.53 Mb), and one 690.50-kb region for the coefficient of MCP on GGA14. Linkage disequilibrium(LD) analysis indicated that the five regions contained high LD blocks, as well as the genes chromosome 26 C6 orf106 homolog(C26 H6 orf106), LOC396098, SH3 and multiple ankyrin repeat domains 2(SHANK2), ETS homologous factor(EHF), and histamine receptor H3-like(HRH3 L), which are known to be involved in the regulation of neurodevelopment, cell proliferation and differentiation, and food intake.Conclusions: Selection for low RFI significantly decreased chicken feed intake, excreta output, and abdominal fat deposition, and increased nutrient digestibility without changing the weight gain. Five novel QTL regions involved in the control of metabolizable efficiency in chickens were identified. These results, combined through nutritional and genetic approaches, should facilitate novel insights into improving feed efficiency in poultry and other species. | Wei Li Ranran Liu Maiqing Zheng Furong Feng Dawei Liu Yuming Guo Guiping Zhao Jie Wen | 2020 | Journal of Animal Science and Biotechnology2020，11，4： | 4 |
| 6 | Incorporation of silica nanoparticles to PLGA electrospun fibers for osteogenic differentiation of human osteoblast-like cells显示文摘The development of bone tissue engineering scaffolds still remains a challenging field,although various biomaterials have been developed for this purpose.Electrospinning is a promising approach to fabricate nanofibers with an interconnected porous structure,which can support cell adhesion,guide cell proliferation and regulate cell differentiation.The aim of this study is to fabricate composite fibers composed of poly(lactic-co-glycolic acid)(PLGA)and silica nanoparticles(NPs)via electrospinning and investigate the effect of PLGA/SiO_(2)composite fibers on the cellular response of osteoblast-like cells(SaOS-2 cells).SEM and EDX analysis showed that silica NPs were homogenously dispersed in the composite fibers.The mechanical behavior of the fibers showed that silica NPs acted as reinforcements at concentrations of 2.5 and 5 mg/ml.The incorporation of silica NPs led to enhancement of cell attachment and spreading on PLGA/SiO_(2)composite fibers.SaOS-2 cells cultured on PLGA/SiO_(2)composite fibers exhibited increased alkaline phosphatase activity,collagen secretion and bone nodules formation.The bone nodules formation of SaOS-2 cells increased along with the amount of incorporated silica NPs.The present findings indicate that PLGA/SiO_(2)composite fibers can stimulate osteogenic differentiation of SaOS-2 cells and may be a promising candidate scaffold for bone tissue engineering. | Xing Yang Yuanyuan Li Xujie Liu Qianli Huang Ranran Zhang Qingling Feng | 2018 | Regenerative Biomaterials2018，5，4： | 4 |
| 7 | Is transformational leadership always good for employee task performance?Examining curvilinear and moderated relationships显示文摘Transformational leadership,generally considered as a desirable leadership style,has positive effects on various performance outcomes of employees;however,its productivity has been called into question because of a relative neglect of its negative aspects.Addressing this gap,an attempt at rethinking the relationship between transformational leadership and employee performance is important.The paradoxical perspective indicates that conflicting positive and negative effects of transformational leadership can coexist,which provides possibility and rationality for thorough consideration of employees'task performance influenced by transformational leaders.Integrating the principle of diminishing marginal utility and the'Too-Much-of-a-Good-Thing(TMGF)'effect,this research explores an inverted U-shaped relationship between transformational leadership and employee task performance.Furthermore,applying social cognitive theory,we assume an employee's proactive personality moderates the curvilinear influence of transformational leadership on employees'task performance.As expected,results from a study of data from 209 supervisorsubordinate relationships from China showed that the inverted U-shaped relationship between transformational leadership and employees'task performance was moderated by employees'proactive personality.Theoretical and practical implications are discussed. | Yashuo Chen Ranran Ning Tong Yang Shangjun Feng Chunjiang Yang | 2018 | Frontiers of Business Research in China2018，12，4： | 2 |

| 11 | Thermal behavior of Mongolian low-rank coals during pyrolysis显示文摘Low temperature pyrolysis behavior of four low-rank coals from the biggest deposits of Mongolia were studied using a fixed-bed reactor and Gray-King retort.The coal samples and resultant chars were analyzed using Fourier transform infrared spectroscopy(FTIR),^(13)C nuclear magnetic resonance(^(13)C NMR)to explore the structure changes and thermogravimetric analyzer coupled with mass spectrometry(TG-MS)was used to investigate the pyrolysis reactivity of coal during thermal decomposition process.The results showed that the aliphatic structure in coal was significantly reduced and the carboxyl groups almost completely decomposed during pyrolysis process at 600℃.The tar yield of Gray-king test is higher than that obtained from the fixed-bed reactor.The gaseous evolution measured by TG-MS during pyrolysis showed that the maximum peaks of evolution of CH_(4),H_(2),C_(2)H_(2),C_(2)H_(5),CO,and CO_(2) gases were well corresponded to the maximum rate of weight loss in the range 428-445℃. | Ariunaa Alyeksandr Zongqing Bai Jin Bai Narangerel Janchig Purevsuren Barnasan Zhihao Feng Ranran Hou Chong He | 2021 | Carbon Resources Conversion2021，4，1： | 1 |

| 14 | Synthesis and Characterization of 4,4′-Dibromoazobenzene显示文摘Azobenzene molecules show excellent application potential in many fields due to their photoisomerization properties.Azobenzene molecules will gradually change from trans-structure to cis-structure under the irradiation of UV.In this paper,we have synthesized 4,4'-dibromoazobenzene molecules and characterized their photoisomerization properties.We found that with the extension of UV time,the trans absorption peak at 343 nm decreased significantly,while the cis absorption peak at 435 nm showed an upward trend.Furthermore,photoisomerization of azobenzene is not a first-order reaction. | Ranran Zhen Wei Lu Yun Zhou Minzhen Feng Ya Wang | 2019 | Organic Polymer Material Research2019，1，2： | 0 |
| 15 | Chiral selection of Troger's base-based macrocycles with different ethylene glycol chains length in crystallization显示文摘In the present work,two Troger's base-based macrocycles(TBBMs)with different bridging ethylene glycol chains(T1,n=1;T3,n=3)were successfully synthesized and studied via the crystal analysis.These two TBBMs possess rare rectangular-like cavities and show chiral selection during the crystallization.T1with short glycol chain(n=1)crystallized as racemates,while T3 with long glycol chain(n=3)was found as meso isomer.In contrast to T1 and T3,for T2(n=2)both rac-T2 and meso isomer R2NS2N-T2has been observed in our previous report.Thus,the synthesis of new TBBMs T1 and T3 with different bridging ethylene glycol chains not only makes the study of TBBMs more systematically,but also helps to understand the relationship between the size of the rectangular cavity and the chiral selection of Troger's base-based macrocycles during their crystallization. | Haohui Feng Yuan Chen Ranran Wang Pengbo Niu Conghao Shi Zhen Yang Ming Cheng Juli Jiang Leyong Wang | 2023 | Chinese Chemical Letters2023，34，7： | 0 |
