| 1 | TD-AltBOC:A new COMPASS B2 modulation显示文摘AltBOC(15,10) is the baseline of COMPASS B2 signal modulation.It is a BOC-like signal having different PN codes in the lower and the upper main split lobes,which allow one signal service per lobe.The two lobes can be received and processed separately like two BPSK(10) signals,or coherently processed to achieve better performance.Interoperability among COMPASS B2,Galileo E5 and GPS L5 is also achievable using AltBOC modulation.However,Galileo's 4-code AltBOC has drawbacks such as low efficiency and great receiver complexity.This paper presents a new modulation type named TD-AltBOC (Time Division AltBOC).The signal generation scheme and receiving method are presented,and are compared with AltBOC in the areas of power spectrum,ranging accuracy,anti-multipath performance,anti-interference performance,processing flexibility and complexity.Analysis results show TD-AltBOC has similar spectrum characteristics,interoperability,flexibility and anti-interference performance with AltBOC.When the frontend bandwidth is more than 50 MHz,TD-AltBOC can achieve better ranging accuracy and anti-multipath performance.It also has such advantages as high efficiency and low receiver complexity.TD-AltBOC could be a good solution to COMPASS B2 navigation signal. | TANG ZuPing ZHOU HongWei WEI JiaoLong YAN Tao LIU YuQi RAN YiHang ZHOU YanLing | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，6： | 20 |

| 3 | Trends in the major causes of death in China, 1982-2010显示文摘Since the introduction of a series of reform and open policies in its economic system in 1976,China has been in a boom period of social and economic fields.Rapid development in economy and the consequent improvement in living conditions,nutrition,and health care help to decrease infant mortality and deaths from infectious diseases,and notably effected the patterns of mortality.For example,respiratory diseases,acute infectious diseases,and tuberculosis were the leading causes of death in 1957,while diseases of heart,cerebrovascular disease,and malignant neoplasm were the fifth,sixth,and seventh leading causes of death.1 Up to 1975,cerebrovascular diseases,diseases of heart,and malignant neoplasm were the top three death causes,followed by respiratory diseases,digestive diseases,and pulmonary tuberculosis.1 A prospective cohort study involving a representative sample of the adult Chinese population was conducted in 2005,which revealed that the five leading causes of death were malignant neoplasm,diseases of heart,cerebrovascular disease,accidents,and infectious diseases among men and diseases of heart,cerebrovascular disease,malignant neoplasm,pneumonia and influenza,and infectious diseases among women. | Lian Zuping Xie Youke Lu Yunxin Huang Dingping Shi Huanzhong | 2014 | Chinese Medical Journal2014，，4： | 13 |
| 4 | The effective pressure law for permeability of clay-rich sandstones显示文摘To study the relative sensitivity of permeability to pore pressure Pp and confining pressure Pc for clay-rich rocks,permeability measurements were performed on samples of four clay-rich sandstones.A new method(hereafter denoted the 'slide method') was developed and used for analyzing the permeability data obtained.The effective pressure coefficients for permeability nk were calculated.The values of nk were found to be greater than 1.0 and insensitive to changes in pressure.These results confirmed observations previously made on clay-rich rocks.Also,the coefficients nk obtained had different characteristics for different samples because of differences in the types of clay they contained.The effective pressure law(σeff=Pc-nkPp) determined using the slide method gave better results about k(σeff) than classic Terzaghi's law(σeff=Pc-Pp). | Zhao Jinzhou Xiao Wenlian Li Min Xiang Zuping Li Lijun Wang Jun | 2011 | Petroleum Science2011，8，2： | 9 |

| 8 | Advances in studies on hepatic stem cells显示文摘The question whether hepatic stem cells exist or not has been debated for several decades. Current researches confirm that there are hepatic stem cells in the liver. Oval cells, putative bipotential hepatic stem cells, are probably located within canals of Hering, portal tracts or branches of biliary trees. Bone marrow is a potential source of oval cells, indicating that there exists a close relationship between liver and hematopoiesis in adulthood. Hepatic stem cells are able to proliferate in vitro and can be induced to differentiate into hepatocytes. This will provide a promising approach of cell transplantation, tissue engineering and gene therapy for liver diseases. In this review, the evidence of their presence, origin, identification, proliferation in vitro, differentiation by induction, application prospects of hepatic stem cells and future directions for the field are discussed. | HE Zuping, TANG Yuefeng, LIU Yabing and FENG Meifu(State Key Laboratory of Biomembrane and Membrane Biotechnology, Institute of Zoology, Chinese Academy of Sciences, Beijing 100080, China) | 2003 | Progress in Natural Science:Materials International2003，13，3： | 2 |

| 11 | A ROBUST PHASE-ONLY DIRECT DATA DOMAIN ALGORITHM BASED ON GENERALIZED RAYLEIGH QUOTIENT OPTIMIZATION USING HYBRID GENETIC ALGORITHM显示文摘A robust phase-only Direct Data Domain Least Squares (D3LS) algorithm based on gen- eralized Rayleigh quotient optimization using hybrid Genetic Algorithm (GA) is presented in this letter. The optimization efficiency and computational speed are improved via the hybrid GA com- posed of standard GA and Nelder-Mead simplex algorithms. First, the objective function, with a form of generalized Rayleigh quotient, is derived via the standard D3LS algorithm. It is then taken as a fitness function and the unknown phases of all adaptive weights are taken as decision variables. Then, the nonlinear optimization is performed via the hybrid GA to obtain the optimized solution of phase-only adaptive weights. As a phase-only adaptive algorithm, the proposed algorithm is sim- pler than conventional algorithms when it comes to hardware implementation. Moreover, it proc- esses only a single snapshot data as opposed to forming sample covariance matrix and operating matrix inversion. Simulation results show that the proposed algorithm has a good signal recovery and interferences nulling performance, which are superior to that of the phase-only D3LS algorithm based on standard GA. | Shao Wei Qian Zuping Yuan Feng | 2007 | Journal of Electronics(China)2007，24，4： | 2 |

| 13 | Cyclic di-adenosine monophosphate regulates the osteogenic and adipogenic differentiation of hPDLSCs via MAPK and NF-κB signaling显示文摘Cyclic di-adenosine monophosphate(c-di-AMP)is a bacterial second messenger that can be recognized by infected host cells and activate the immunoinflammatory response.The purpose of this study is to demonstrate the effect of c-di-AMP on the differentiation of human periodontal ligament stem cells(hPDLSCs)and its underlying mechanisms.In the present study,we find that the gingival crevicular fluid(GCF)of patients with chronic periodontitis has a higher expression level of c-di-AMP than that of healthy people.In vitro,c-di-AMP influences the differentiation of hPDLSCs by upregulating Toll-like receptors(TLRs);specifically,it inhibits osteogenic differentiation by activating NF-κB and ERK/MAPK and promotes adipogenic differentiation through the NF-κB and p38/MAPK signaling pathways.Inhibitors of TLRs or activated pathways reduce the changes induced by c-di-AMP.Our results establish the potential correlation among bacterial c-di-AMP,periodontal tissue homeostasis and chronic periodontitis pathogenesis. | Sirui Chen Zuping Wu Yuying He Li Zhu Jiahe Wang Hengyi Lin Jing Xie Chenchen Zhou Shujuan Zou | 2023 | Acta Biochimica et Biophysica Sinica2023，55，3： | 1 |
