| 1 | Principles and construction of MSD adder in ternary optical computer显示文摘The two remarkable features of ternary values and a massive unit with thousands bits of parallel computation will make the ternary optical computer (TOC) with modified signed-digit (MSD) adder more powerful and e?cient than ever before for numerical calculations. Based on the decrease-radix design presented previously, a TOC can satisfy either a user requiring huge capacity for data calculations or one with a moderate amount of data, if it is equipped with a prepared adder. Furthermore, with the application of pipelined operations and the proposed data editing technique, the e?ciency of the prepared adder can be greatly improved, so that each calculated result can be obtained almost within one clock cycle. It is hopeful that by employing a MSD adder, users will be able to enter a new dimension with the creation of a new multiplier, new divider, as well as new matrix operator in a TOC in the near future. | JIN Yi SHEN YunFu PENG JunJie XU ShiYi DING GuangTai YUE DongJian YOU HaiHang | 2010 | Science China(Information Sciences)2010，53，11： | 26 |
| 2 | Evolution of Sedimentation and Tectonics of the Youjiang Composite Basin, South China显示文摘Located at the southern margin of the South China plate, the Youjiang basin is a closely related to the NW- and NE-trending syndepositional faults in respect to the configuration and structure of the basin. The evolution of the Youjiang basin progressed through two stages. In the Hercynian period, the opening of the Ailaoshan-Honghe ocean basin gave rise to a number of NW-trending rift belts in the Youjiang area. During this period, deep-water sediments were dominant and the basin was possesed of the characteristics of the rift system of passive continental margins. In the early Indosinian after the Dongwu movement, the circum - Pacific tectonism led to a major change in the configuration and structure of the basin. In the meantime, the Ailaoshan ocean basin began to be subducted towards the northeast, thus causing the basin to be split and expand again, and then the basin developed into the stage of the back -arc basin. At the end of the Indosinian period, the basin gradually closed from east to west, | Zeng Yunfu, Liu Wenjun, Cheng Hongde, Zheng Rongcai, Zhang Jinquan Chengdu Institute of Technology, Chengdu, SichuanLi Xiaoquan and Jiang Tingcao Regional Geological Survey Party of Guangxi,Guilin,Guangxi Jiang M inxi | 1995 | Acta Geologica Sinica(English Edition)1995，69，4： | 18 |
| 3 | Neuroprotective effect of ischemic preconditioning in focal cerebral infarction: relationship with upregulation of vascular endothelial growth factor显示文摘Neuroprotection by ischemic preconditioning has been confirmed by many studies, but the precise mechanism remains unclear. In the present study, we performed cerebral ischemic preconditioning in rats by simulating a transient ischemic attack twice(each a 20-minute occlusion of the middle cerebral artery) before inducing focal cerebral infarction(2 hour occlusion-reperfusion in the same artery). We also explored the mechanism underlying the neuroprotective effect of ischemic preconditioning. Seven days after occlusion-reperfusion, tetrazolium chloride staining and immunohistochemistry revealed that the infarct volume was significantly smaller in the group that underwent preconditioning than in the model group. Furthermore, vascular endothelial growth factor immunoreactivity was considerably greater in the hippocampal CA3 region of preconditioned rats than model rats. Our results suggest that the protective effects of ischemic preconditioning on focal cerebral infarction are associated with upregulation of vascular endothelial growth factor. | Yong Liu Suiqiang Zhu Yunfu Wang Jingquan Hu Lili Xu Li Ding Guangjian Liu | 2014 | Neural Regeneration Research2014，9，11： | 15 |
| 4 | Architecture design for reliable and reconfigurable FPGA-based GNC computer for deep space exploration显示文摘SRAM(static random access memory)-based FPGA(field programmable gate array), owing to its large capacity, high performance, and dynamical reconfiguration, has become an attractive platform for So PC(system on programmable chip) development. However, as the configuration memory and logic memory of the SRAM-based FPGA are highly susceptible to SEUs(single-event upsets) in deep space, it is a challenge to design and implement a highly reliable FPGA-based system for spacecraft, and no practical architecture has been proposed. In this paper, a new architecture for a reliable and reconfigurable FPGAbased computer in a highly critical GNC(guidance navigation and control) system is proposed. To mitigate the effect of an SEU on the system, multi-layer reconfiguration and multi-layer TMR(triple module redundancy) techniques are proposed, with a reliable reconfigurable real-time operating system(Space OS) managing the system level fault tolerance of the computer in the architecture. The proposed architecture for the reconfigurable FPGA-based computer has been implemented with COTS(commercial off the shelf) FPGA and has firstly been applied to the GNC system of a circumlunar return and reentry flight vehicle. The in-orbit results show that the proposed architecture is capable of meeting the requirements of high reliability and high availability, and can provide the expressive varying functionality and runtime flexibility for an FPGA-based GNC computer in deep space. | YANG MengFei LIU Bo GONG Jian LIU HongJin HU HongKai DONG YangYang SHI Lei ZHAO YunFu MIAO ZhiFu | 2016 | Science China(Technological Sciences)2016，59，2： | 10 |
| 5 | Pioneering function of Isl1 in the epigenetic control of cardiomyocyte cell fate显示文摘Generation of widely differing and specialized cell types from a single totipotent zygote involves large-scale transcriptional changes and chromatin reorganization. Pioneer transcription factors play key roles in programming the epigenome and facilitating recruitment of additional regulatory factors during successive cell lineage specification and differentiation steps. Here we show that Isl1 acts as a pioneer factor driving cardiomyocyte lineage commitment by shaping the chromatin landscape of cardiac progenitor cells. Using an Isl1 hypomorphic mouse line which shows congenital heart defects, genome-wide profiling of Isl1 binding together with RNA- and ATAC-sequencing of cardiac progenitor cells and their derivatives, we uncover a regulatory network downstream of Isl1 that orchestrates cardiogenesis. Mechanistically, we show that Isl1 binds to compacted chromatin and works in concert with the Brg1-Baf60c-based SWI/SNF complex to promote permissive cardiac lineage-specific alterations in the chromatin landscape not only of genes with critical functions in cardiac progenitor cells, but also of cardiomyocyte structural genes that are highly expressed when Isl1 itself is no longer present. Thus, the Isl1/Brg1-Baf60c complex plays a crucial role in orchestrating proper cardiogenesis and in establishing epigenetic memory of cardiomyocyte fate commitment. | Rui Gao Xingqun Liang Sirisha Cheedipudi Julio Cordero Xue Jiang Qingquan Zhang Luca Caputo Stefan Günther Carsten Kuenne Yonggang Ren Shoumo Bhattacharya Xuejun Yuan Guillermo Barreto Yihan Chen Thomas Braun Sylvia M.

| 6 | Principle of a one-step MSD adder for a ternary optical computer显示文摘While investigating a three-step MSD adder and the reliability thereof for ternary optical computers(TOC),the principle of one-step MSD addition was found.An important concept,the mid-bit transform,is proposed.Next,the important mid-bit transform table(MTT)for 3-bit MSD input and the corresponding mid-bit transform unit(MTU)are obtained.Using the principle,the concept structure of a one-step MSD adder is proposed such that the sum of the addition can be obtained easily in one step in parallel.By restricting the input symbols,a simplified MTT is obtained and the principle of a one-step adder with restricted input symbols is introduced,together with the corresponding simplified concept structure of a one-step MSD adder.Two examples are presented to demonstrate the principles of one-step MSD adders.This work lays the theoretic foundation for the design of an optical MSD adder in future study. | SHEN YunFu PAN Lei | 2014 | Science China(Information Sciences)2014，57，1： | 4 |
| 7 | On the Carboniferous Sequence Stratigraphy in the Tazhong Area, Xinjiang——A Model of the Sequence Stratigraphy Framework of Intracratonic Depressional Basins显示文摘The Carboniferous prototype sedimentary basin in the Tazhong (Central Tarimbasin) area is recognized as a compressive intracratonic depressional one. Three type Ⅰ sequenceboundaries and three type Ⅱ sequence boundaries can be identified in the CarboniferousSystem, which can accordingly be divided into five sedimentary sequences. These sequencespossess stratigraphic characters of the standard sequence and correspond to the depositionalstratigraphic unit of a third-order eustatic cycle. They can be regionally or globally correlatedwith each other. The framework of sequence stratigraphy of the intracratonict basin in thestudy area distinctly differs from that of the passive continental-margin basin in the lack ofdepositional systems of early-middle lowstand, poor development of the deeply incised valleyand condensed section of the maximum sea-flood, good development of type Ⅱ sequenceboundaries and coastal plain depositional systems coexisting with shelf-type fan deltas underwet climatic conditions, Which consequently led to the formation of a paralic lithofacies frame-work. | Guo Jianhua Zeng Yunfu Zhai Yonghong and Gao Zhenzhong Jianghan Petroleum Institute, Jingsha, Hubei Chengdu Institute of Technology, Chengdu, Sichuan Jianghan Petroleum Institute, Jingsha, Hubei Liu Xinzhu | 1997 | Acta Geologica Sinica(English Edition)1997，71，3： | 4 |

| 10 | Tumor-associated Exosomes Are Involved in Hepatocellular Carcinoma Tumorigenesis, Diagnosis, and Treatment显示文摘Hepatocellular carcinoma(HCC)has become a challenging disease worldwide.There are still limitations in the diagnosis and treatment of HCC,and its high metastatic capacity and high recurrence rate are the main reasons for its poor prognosis.The ability of extracellular vesicles(EVs)to transfer functionally-active substances and their widespread presence in almost all body fluids suggest their unprecedented potential in the study of various cancers.The unique physicochemical properties of EVs determine their potential as antitumor vaccines and drug carriers.In the last decade,the study of EVs in HCC has evolved from a single hot topic to a system with considerable scale.This paper summarizes the role of EVs,especially exosomes,in the occurrence,metastasis and tumor immunity of HCC,reviews their applications in tumor diagnosis,prognosis and treatment,describes the pros and cons of these studies,and looks forward towards the future research directions of EVs in HCC. | Hang Wang Liang Yu Peng Huang Yongxu Zhou Wangyang Zheng Nanfeng Meng Risheng He Yi Xu Tey Sze Keong Yunfu Cui | 2022 | Journal of Clinical and Translational Hepatology2022，10，3： | 2 |

| 12 | Global antimicrobial resistance:a system-wide comprehensive investigation using the Global One Health Index显示文摘Background:Antimicrobial resistance(AMR)is one of the top ten global public health challenges.However,given the lack of a comprehensive assessment of worldwide AMR status,our objective is to develop a One Health-based system-wide evaluation tool on global AMR.Methods:We have further developed the three-hierarchical Global One Health Index(GOHI)-AMR indicator scheme,which consists of five key indicators,17 indicators,and 49 sub-indicators,by incorporating 146 countries'data from diverse authoritative databases,including WHO's Global Antimicrobial Resistance and Use Surveillance System(GLASS)and the European CDC.We investigated the overall-or sub-rankings of GOHI-AMR at the international/regional/national levels for data preprocessing and score calculation utilizing the existing GOHI methodology.Additionally,a correlation analysis was conducted between the GOHI-AMR and other socioeconomic factors.Results:The average GOHI-AMR score for 146 countries is 38.45.As expected,high-income countries(HICs)outperform the other three income groups on overall rankings and all five key indicators of GOHI-AMR,whereas lowincome countries unexpectedly outperform upper-middle-income countries and lower-middle-income countries on the antibiotics-resistant key indicator(ARR)and ARR-subordinate indicators,including carbapenem-,β-lactam-,and quinolone resistance,and even HICs on aminoglycoside resistance.There were no significant differences among the four groups on the environmental-monitoring indicator(P>0.05).GOHI-AMR was positively correlated with gross domestic product,life expectancy,and AMR-related publications,but negatively with natural growth rate and chronic respiratory disease.In contrast to Cyprus,the remarkably lower prevalence of'ESKAPE pathogens'in high-scoring Sweden and Denmark highlights Europe's huge gaps.China and Russia outperformed the other three BRICS countries on all key indicators,particularly India's ARR and Brazil's AMR laboratory network and coordination capacity.Furthermore,significant internal disparities in carbapenem-resistant Klebsiella pneumoniae(CRKP)and methicillin-resistant Staphylococcus aureus(MRSA)prevalence were observed between China and the USA,with MRSA prevalence both gradually declining,whereas CRKP prevalence has been declining in the USA but increasing in China,consistent with higher carbapenems-related indicator'performance in USA.Conclusions:GOHI-AMR is the most comprehensive tool currently available for the assessment of AMR status worldwide.We discovered unique features impacting AMR in each country and offered precise recommendations to improve the capacity to tackle AMR in low-ranking countries. | Nan Zhou Zile Cheng Xiaoxi Zhang Chao Lv Chaoyi Guo Haodong Liu Ke Dong Yan Zhang Chang Liu Yunfu Chang Sheng Chen Xiaokui Guo Xiao-Nong Zhou Min Li Yongzhang Zhu | 2022 | Infectious Diseases of Poverty2022，11，4： | 2 |
| 13 | Rapamycin reverses ferroptosis by increasing autophagy in MPTP/MPP+-induced models of Parkinson's disease显示文摘Parkinson’s disease is a neurodegenerative disorder,and fe rroptosis plays a significant role in the pathological mechanism underlying Parkinson’s disease.Rapamycin,an autophagy inducer,has been shown to have neuroprotective effects in Parkinson’s disease.However,the link between rapamycin and ferroptosis in Parkinson’s disease is not entirely clear.In this study,rapamycin was administe red to a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced Parkinson’s disease mouse model and a 1-methyl-4-phenylpyridinium-induced Parkinson’s disease PC12 cell model.The results showed that rapamycin improved the behavioral symptoms of Parkinson’s disease model mice,reduced the loss of dopamine neurons in the substantia nigra pars compacta,and reduced the expression of ferroptosis-related indicators(glutathione peroxidase 4,recombinant solute carrier family 7,member 11,glutathione,malondialdehyde,and reactive oxygen species).In the Parkinson’s disease cell model,rapamycin improved cell viability and reduced ferro ptosis.The neuroprotective effect of rapamycin was attenuated by a ferroptosis inducer(methyl(1S,3R)-2-(2-chloroacetyl)-1-(4-methoxycarbonylphenyl)-1,3,4,9-tetrahyyridoindole-3-carboxylate)and an autophagy inhibitor(3-methyladenine).Inhibiting ferro ptosis by activating autophagy may be an important mechanism by which rapamycin exerts its neuroprotective effects.Therefo re,the regulation of ferroptosis and autophagy may provide a therapeutic target for drug treatments in Parkinson’s disease. | Tongyu Liu Peihan Wang Huan Yin Xiangfei Wang Jing Lv Jiang Yuan Jing Zhu Yunfu Wang | 2023 | Neural Regeneration Research2023，18，11： | 1 |
