| 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 | Prenatal and early life home environment exposure in relation to preschool children's asthma, allergic rhinitis and eczema in Taiyuan, China显示文摘Prenatal and early life home environment might be related to children’s asthma or allergic diseases later in life.A cross-sectional epidemiological study was designed and a questionnaire survey was performed in 3700 preschool children in urban areas in Taiyuan,Shanxi Province,China.Questions on children’s asthma and allergic diseases from the International Study on Asthma and Allergies in Childhood(ISAAC)were integrated with questions on home environment from the Swedish Dampness in Buildings and Health(DBH)study,appropriately modified for Chinese life habits.By multivariate regression analyses controlling for age,gender,heredity,location in urban/suburban or rural areas,environmental tobacco smoke(ETS)and breastfeeding,we found that home new furniture(HNF)before birth(referring to 1 year before pregnancy and during pregnancy)was positively associated with wheezing ever(odds ratio(OR)1.23 with 95%CI of 1.03–1.48)and wheezing last 12 months(1.24,1.00–1.54),allergic rhinitis(AR)(1.26,1.06–1.51),and eczema(1.42,1.01–1.99).HNF between 0–1 years old was also positively associated with wheezing last 12 months.Home new decoration(HND)during 0–1 years old was positively associated with AR symptoms and eczema symptoms,more in the last 12 months.Stronger positive associations were found for signs of home mold and dampness with almost all children’s asthmatic and allergic symptoms(OR ranging from 1.23–1.85,P<0.05).By mutual adjustment between HNF before children’s birth and home mold or dampness,all the significance remained unchanged.Prenatal HNF and home mold or dampness was independently associated with children’s asthmatic and allergic diseases later in life. | ZHAO ZhuoHui ZHANG Xin LIU RanRan NORBACK Dan WIESLANDER Gunilla CHEN Jie SUNDELL Jan | 2013 | Chinese Science Bulletin2013，58，34： | 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 |

| 6 | 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 |
| 7 | Image denoising using statistical model based on quaternion wavelet domain显示文摘Image denoising is the basic problem of image processing.Quaternion wavelet transform is a new kind of multiresolution analysis tools.Image via quaternion wavelet transform,wavelet coefficients both in intrascale and in interscale have certain correlations.First,according to the correlation of quaternion wavelet coefficients in interscale,non-Gaussian distribution model is used to model its correlations,and the coefficients are divided into important and unimportance coefficients.Then we use the non-Gaussian distribution model to model the important coefficients and its adjacent coefficients,and utilize the MAP method estimate original image wavelet coefficients from noisy coefficients,so as to achieve the purpose of denoising.Experimental results show that our algorithm outperforms the other classical algorithms in peak signal-to-noise ratio and visual quality. | YIN Ming LIU Wei KONG Ranran | 2012 | Computer Aided Drafting,Design and Manufacturing2012，22，2： | 4 |
| 8 | 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 |

| 10 | A selected population study reveals the biochemical mechanism of intramuscular fat deposition in chicken meat显示文摘Background:Increasing intramuscular fat(IMF)is an important strategy to improve meat quality,but the regulation mechanism of IMF deposition needs to be systematically clarified.Results:A total of 520 chickens from a selected line with improved IMF content and a control line were used to investigate the biochemical mechanism of IMF deposition in chickens.The results showed that the increased IMF would improve the flavor and tenderness quality of chicken meat.IMF content was mainly determined both by measuring triglyceride(TG)and phospholipid(PLIP)in muscle tissue,but only TG content was found to be decisive for IMF deposition.Furthermore,the increase in major fatty acid(FA)components in IMF is mainly derived from TGs(including C16:0,C16:1,C18:1n9c,and C18:2n6c,etc.),and the inhibition of certain very-long-chain FAs would help to IMF/TG deposition.Conclusions:Our study elucidated the underlying biochemical mechanism of IMF deposition in chicken:Prevalent accumulation of long-chain FAs and inhibitions of medium-chain FAs and very long chain FA would jointly result in the increase of TGs with the FA biosynthesis and cellular uptake ways.Our findings will guide the production of high-quality chicken meat. | Huanxian Cui Lu Liu Xiaojing Liu Yongli Wang Na Luo Xiaodong Tan Yuting Zhu Ranran Liu Guiping Zhao Jie Wen | 2022 | Journal of Animal Science and Biotechnology2022，13，5： | 2 |

| 14 | Electrostatic self-assembly of 2D/2D CoWO_(4)/g-C_(3)N_(4)p-n heterojunction for improved photocatalytic hydrogen evolution:Built-in electric field modulated charge separation and mechanism unveiling显示文摘Two-dimensional(2D)semiconductor heterojunctions are considered as an effective strategy to achieve fast separation of photoinduced carriers.Herein,a novel CoWO_(4)/g-C_(3)N_(4)(CWO/CN)p–n junction was synthesized using an electrostatic selfassembly method.The constructed 2D/2D p–n heterostructure had a rich hetero-interface,increased charge density,and fast separation efficiency of photoinduced carriers.The in-situ Kelvin probe force microscopy confirmed that the separation pathway of photoinduced carriers through the interface obeyed an II-scheme charge transfer mechanism.Experimental results and density functional theory calculations indicated the differences of work function between CWO and CN induced the generation of built-in electric field,ensuring an efficient separation and transfer process of photoinduced carriers.Under the optimized conditions,the CWO/CN heterojunction displayed enhanced photocatalytic H_(2)generation activity under full spectrum and visible lights irradiation,respectively.Our study provides a novel approach to design 2D/2D hetero-structured photocatalysts based on p–n type semiconductor for photocatalytic H_(2)generation. | Haiyang Wang Ranran Niu Jianhui Liu Sheng Guo Yongpeng Yang Zhongyi Liu Jun Li | 2022 | Nano Research2022，15，8： | 1 |
