| 2 | The Sunway TaihuLight supercomputer: system and applications显示文摘The Sunway Taihu Light supercomputer is the world's first system with a peak performance greater than 100 PFlops. In this paper, we provide a detailed introduction to the Taihu Light system. In contrast with other existing heterogeneous supercomputers, which include both CPU processors and PCIe-connected many-core accelerators(NVIDIA GPU or Intel Xeon Phi), the computing power of Taihu Light is provided by a homegrown many-core SW26010 CPU that includes both the management processing elements(MPEs)and computing processing elements(CPEs) in one chip. With 260 processing elements in one CPU, a single SW26010 provides a peak performance of over three TFlops. To alleviate the memory bandwidth bottleneck in most applications, each CPE comes with a scratch pad memory, which serves as a user-controlled cache. To support the parallelization of programs on the new many-core architecture, in addition to the basic C/C++and Fortran compilers, the system provides a customized Sunway Open ACC tool that supports the Open ACC2.0 syntax. This paper also reports our preliminary efforts on developing and optimizing applications on the Taihu Light system, focusing on key application domains, such as earth system modeling, ocean surface wave modeling, atomistic simulation, and phase-field simulation. | Haohuan FU Junfeng LIAO Jinzhe YANG Lanning WANG Zhenya SONG Xiaomeng HUANG Chao YANG Wei XUE Fangfang LIU Fangli QIAO Wei ZHAO Xunqiang YIN Chaofeng HOU Chenglong ZHANG Wei GE Jian ZHANG Yangang WANG Chunbo ZHOU Guangwen YANG | 2016 | Science China(Information Sciences)2016，59，7： | 45 |

| 4 | Predicting the spread of nuclear radiation from the damaged Fukushima Nuclear Power Plant显示文摘Japan suffered a M9.0 earthquake and massive tsunami on March 11, 2011, which seriously damaged the Fukushima Nuclear Power Plant and caused a nuclear crisis. The spread of nuclear radiation from the power plant through the atmosphere and ocean was predicted with a short-term climate forecasting model and an ocean circulation model under some idealized assumptions. If nuclear matter were leaked in the near-ground layer of 992 hPa, the climate model results show that the nuclear radiation would cover North America 10 days after the initial leakage, with the concentration at the forefront dramatically reduced to 10 millionths of the initial model concentration at the source. The radiation would span Europe in 15 days and cover much of the Northern Hemisphere in 30 days. If the initial leakage was assumed to occur in the layer 5000-m above the ground, the radiation would cover Europe in 10 days and cover much of the Northern Hemisphere in 15 days. Moreover, under the assumption that the nuclear matter leaked in the 10000-m layer, the radiation would affect much of China after 10 days. The ocean circulation model indicates that the nuclear material would be slowly transported northeast of Fukushima and reach 150°E in 50 days, and the nuclear debris in the ocean would be confined to a narrow band. Compared with the spread in the ocean, the area affected by leaked nuclear radiation in the atmosphere would be very large. Atmospheric monitors in North America and Europe will be helpful for estimating the effect in China of any leaked nuclear material. | QIAO FangLi WANG GuanSuo ZHAO Wei ZHAO JieChen DAI DeJun SONG YaJuan SONG ZhenYa | 2011 | Chinese Science Bulletin2011，56，18： | 18 |
| 5 | Complement C3 activation regulates the production of tRNA-derived fragments Gly-tRFs and promotes alcohol-induced liver injury and steatosis显示文摘Complement is known to play a role in alcoholic fatty liver disease (AFLD), but the underlying mechanisms are poorly understood, thereby constraining the development of a rational approach for therapeutic intervention in the complement system. C3 deficiency has been shown to impart protective effects against ethanol-induced hepatic steatosis and inflammation. Here we demonstrate a protection effect in wild-type mice by treatment with CR2-Crry, a specific inhibitor of C3 activation. The expression of glycine transfer (t) RNA-derived fragments (Gly-tRFs) is upregulated in ethanol-fed mice and inhibition of Gly-tRFs in vivo decreases chronic ethanol feeding-induced hepatosteatosis without affecting inflammation. The expression of Gly-tRF was downregulated in C3-deficient or CR2-Crry-treated mice, but not in C5-deficient mice;Gly-tRF expression was restored by the C3 activation products C3a or Asp (C3a-des-Arg) via the regulation of CYP2E1. Transcriptome profiling of hepatic tissues showed that Gly-tRF inhibitors upregulate the expression of sirtuin1 (Sirt1) and subsequently affect downstream lipogenesis and β-oxidation pathways. Mechanistically, Gly-tRF interacts with AGO3 to downregulate Sirt1 expression via sequence complementarity in the 3′ UTR. Notably, the expression levels of C3d, CYP2E1 and Gly-tRF are upregulated, whereas Sirt1 is decreased in AFLD patients compared to healthy controls. Collectively, our findings suggest that C3 activation products contribute to hepatosteatosis by regulating the expression of Gly-tRF. Complement inhibition at the C3 activation step and treatment with Gly-tRF inhibitors may be potential and precise therapeutic approaches for AFLD. | Fudi Zhong Zhigao Hu Keqing Jiang Biao Lei Zhan Wu Guandou Yuan Hongliang Luo Chunqiang Dong Bo Tang Chaowen Zheng Shuai Yang Yonglian Zeng Zhenya Guo Shuiping Yu Huizhao Su Guo Zhang Xiaoqiang Qiu Stephen Tomlinson Songqing He | 2019 | Cell Research2019，29，7： | 14 |

| 7 | 多极源随钻声波测井实验分析显示文摘本文针对随钻声波测井中钻铤波干扰地层声波测量的问题,设计了小尺寸随钻声波测井探头,在实验室内开展了多极源(单极源、偶极源和四极源)随钻声波测井实验研究.先在水池中对裸露的探头进行了随钻测量,记录到了沿钻铤传播的直达钻铤波,并获得了不同声源激发的钻铤波速度.之后在砂岩和有机玻璃模型中进行了随钻声波测井实验,观测到多极源随钻测井的全波波形,并通过与水池中实验结果的对比,分析了井中钻铤波的传播特性.特别地,在偶极随钻测井实验中不仅记录到了偶极一阶钻铤波,还观测到对弯曲波干扰较大的偶极二阶钻铤波,进而研究了不同声源频率下该波群的响应特性及其对弯曲波测量的影响.此外,基于单极源和偶极源随钻声波测井实验数据,本文发现:随着声源频率的增加,单极和偶极钻铤波的传播特性不同,但它们在测井全波中的相对幅度均降低,进而可从测井全波中较好地提取地层的声波速度.本文实验结果对随钻声波测井仪器设计及测井数据解释具有重要意义. | 王军 Zhu Zhenya 郑晓波 | 2016 | 地球物理学报2016，59，5： | 10 |
| 8 | The correctness to the spuriously simulated semi-annual cycle of the sea surface temperature in the equatorial eastern Pacific显示文摘One of the challenges faced by the climate model of the Community Climate System Model version 3 (CCSM3) is the spuriously simulated semi-annual cycle of the sea surface temperature (SST) in the equatorial eastern Pacific. This model bias has limited the performance of the climate simulation and prediction. Based on the surface wave-circulation coupled theory, an atmosphere-wave-ocean coupled model was developed, which incorporates the MASNUM (key laboratory of Marine Sciences and Numerical Modeling) wave number spectral model into CCSM3. The new coupled atmosphere-wave-ocean model successfully removes the spurious semi-annual cycle simulated by the original CCSM3 and reasonably produces an SST annual cycle with warm and cold phases in April and August, respectively. The correlation between the simulated and observed SST in the equatorial eastern Pacific is improved from 0.66 to 0.93. The ocean surface layer heat budget analysis indicates that the wave-induced vertical mixing is responsible for improving the simulation of the SST seasonal cycle in the equatorial eastern Pacific. | SONG ZhenYa QIAO FangLi WANG ChunZai | 2011 | Science China Earth Sciences2011，54，3： | 10 |
| 9 | Timing of transplantation of autologous bone marrow derived mesenchymal stem cells for treating myocardial infarction显示文摘It is still unclear whether the timing of intracoronary stem cell therapy affects the therapeutic response in patients with myocardial infarction.The natural course of healing the infarction and the presence of putative homing signals within the damaged myocardium appear to favor cell engraftment during the transendothelial passage in the early days after reperfusion.However,the adverse inflammatory environment,with its high oxidative stress,might be deleterious if cells are administered too early after reperfusion.Here we highlight several aspects of the timing of intracoronary stem cell therapy.Our results showed that transplantation of bone marrow mesenchymal stem cells at 2 4 weeks after myocardial infarction is more favorable for reduction of the scar area,inhibition of left ventricular remodeling,and recovery of heart function.Coronary injection of autologous bone marrow mesenchymal stem cells at 2 4 weeks after acute myocardial infarction is safe and does not increase the incidence of complications. | CHEN YiHuan TENG XiaoMei CHEN WeiQian YANG JunJie YANG ZiYing YU YunSheng SHEN ZhenYa | 2014 | Science China(Life Sciences)2014，57，2： | 7 |

| 11 | Release of VEGF and BMP9 from injectable alginate based composite hydrogel for treatment of myocardial infarction显示文摘Myocardial infarction(MI)is one of cardiovascular diseases that pose a serious threat to human health.The pathophysiology of MI is complex and contains several sequential phases including blockage of a coronary artery,necrosis of myocardial cells,inflammation,and myocardial fibrosis.Aiming at the treatment of different stages of MI,in this work,an injectable alginate based composite hydrogel is developed to load vascular endothelial active factor(VEGF)and silk fibroin(SF)microspheres containing bone morphogenetic protein 9(BMP9)for releasing VEGF and BMP9 to realize their respective functions.The results of in vitro experiments indicate a rapid initial release of VEGF during the first few days and a relatively slow and sustained release of BMP9 for days,facilitating the formation of blood vessels in the early stage and inhibiting myocardial fibrosis in the long-term stage,respectively.Intramyocardial injection of such composite hydrogel into the infarct border zone of mice MI model via multiple points promotes angiogenesis and reduces the infarction size.Taken together,these results indicate that the dual-release of VEGF and BMP9 from the composite hydrogel results in a collaborative effect on the treatment of MI and improvement of heart function,showing a promising potential for cardiac clinical application. | Yong Wu Tianqi Chang Weiqian Chen Xiaoyu Wang Jingjing Li Yueqiu Chen You Yu Zhenya Shen Qian Yu Yanxia Zhang | 2021 | Bioactive Materials2021，6，2： | 7 |

| 13 | Effect of illumination intensity and light application time on secondary organic aerosol formation from the photooxidation of α-pinene显示文摘Secondary organic aerosol (SOA) formation from hydroxyl radical (OH.) initiated photooxidation of α-pinene was investigated in a home-made smog chamber. The size distribution of SOA particles was measured using aerodynamic particle sizer spectrometer. The effects of illumination intensity and light application time on SOA formation for α-pinene were evaluated. Experimental results show that the concentration of SOA particles increased significantly with an increasing of illumination intensity, and the light application time, the concentration, and the size of SOA particles were also increased. In addition, the factors influencing the formation of SOA were discussed. In addition, this article compared the effect of α-pinene with that of toluene, and discussed the contribution of α-pinene to SOA formation. | LIU Xianyun, ZHANG Weijun, HUANG Mingqiang, WANG Zhenya, HAO Liqing, ZHAO Wenwu Laboratory of Environment Spectroscopy, Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences,Hefei 230031, China. | 2009 | Journal of Environmental Sciences2009，21，4： | 7 |
| 14 | The prediction on the 2015/16 El Nino event from the perspective of FIO-ESM显示文摘Recently atmospheric and oceanic observations indicate the tropical Pacific is at the El Ni?o condition. However,it's not clear whether this El Ni?o event of this year is comparable to the very strong one of 1997/98 which brought huge influence on the whole world. In this study, based on the Ensemble Adjusted Kalman Filter(EAKF)assimilation scheme and First Institute of Oceanography-Earth System Model(FIO-ESM), the assimilation system is setup, which can provide reasonable initial conditions for prediction. And the hindcast results suggest the skill of El Ni?o-Southern Oscillation(ENSO) prediction is comparable to other dynamical coupled models. Then the prediction for 2015/16 El Ni?o by using FIO-ESM is started from 1 November 2015. The ensemble results indicate that the 2015/16 El Ni?o will continue to be strong. By the end of 2015, the strongest strength is very like more than 2.0°C and the ensemble mean strength is 2.34°C, which indicates 2015/16 El Ni?o event will be very strong but slightly less than that of 1997/98 El Ni?o event(2.40°C) calculated relative a climatology based on the years1992–2014. The prediction results also suggest 2015/16 El Ni?o event will be a transition to ENSO-neutral level in the early spring(FMA) 2016, and then may transfer to La Ni?a in summer 2016. | SONG Zhenya SHU Qi BAO Ying YIN Xunqiang QIAO Fangli | 2015 | Acta Oceanologica Sinica2015，34，12： | 6 |
| 15 | Real-time detection of individual secondary organic aerosol particle from photooxidation of toluene using aerosol time of flight mass spectrometer显示文摘Photooxidation of the aromatic hydrocarbon toluene and its subsequent reactions were carried out using UV-irradiation of toluene/CH3ONO/NO/air mixtures in a home-made smog chamber. The secondary organic aerosols could be formed after those oxidation products of semi-volatile or- ganic compounds were partitioned between gas phase and particle phase. The aerosol time of flight mass spectrometer (ATOFMS) was used to measure size and molecular composition of individual secondary organic aerosol particle. Size distribution and chemical composition of secondary organic aerosol were got in real time. | WANG Zhenya HAO Liqing ZHOU Liuzhu GUO Xiaoyong ZHAO Wenwu FANG Li ZHANG Weijun | 2006 | Science China Chemistry2006，49，3： | 5 |
| 16 | The effect of the wave-induced mixing on the upper ocean temperature in a climate model显示文摘The significant underestimation of sea surface temperature(SST)and the temperature in the upper ocean is one of common problems in present climate models.The influence of the wave-induced mixing on SST and the temperature in the upper ocean was examined based on a global climate model.The results from the model coupled with wave-induced mixing showed a significant improvement in the simulation of SST and the temperature in the upper ocean compared with those of the original model without wave effects.Although there has still a cold bias,the new simulation is much closer to the climatology,especially in the northern ocean and tropical ocean.This study indicates that some important physical processes in the accurate simulation of the ocean may be ignored in present climate models,and the wave-induced mixing is one of those factors.Thus,the wave-induced mixing(or the effect of surface waves)should be incorporated properly into climate models in order to simulate or forecast the ocean,then climate system,more accurately. | HUANG Chuanjiang QIAO Fangli SONG Zhenya | 2008 | Acta Oceanologica Sinica2008，27，3： | 5 |
| 17 | Experimental study of photooxidation products of ethylbenzene显示文摘Smog chamber experiments were performed to investigate the composition of products formed from photooxidation of aromatic hydrocarbon ethylbenzene.Vacuum ultraviolet photoionization mass spectrometer and aerosol time-of-flight mass spectrometer were used to measure the products in the gas and particle phases in real-time.Experimental results demonstrated that ethylphenol,methylglyoxal,phenol,benzaldehyde,and 2-ethylfurane were the predominant photooxidation products in both the gas and particle phases.However,there were some dierences between detected gas phase products and those of particle phase,for example,2-ethylfurane,ethylglyoxylic acid,nitroethylbenzene,3,4-dioxopentanal and ethyl-nitrophenol were only existing in the particle-phase. The possible reaction mechanisms leading to these products were also discussed and proposed. | Mingqiang Huang Weijun Zhang Liqing Hao Zhenya Wang Li Fang Ruihong Kong Xiaobin Shan Fuyi Liu Liusi Sheng | 2010 | Journal of Environmental Sciences2010，22，10： | 5 |

| 19 | Could CMIP6 climate models reproduce the early-2000s global warming slowdown?显示文摘The unexpected global warming slowdown during 1998–2013 challenges the existing scientific understanding of global temperature change mechanisms,and thus the simulation and prediction ability of state-of-the-art climate models since most models participating in phase 5 of the Coupled Model Intercomparison Project(CMIP5)cannot simulate it.Here,we examine whether the new-generation climate models in CMIP6 can reproduce the recent global warming slowdown,and further evaluate their capacities for simulating key-scale natural variabilities which are the most likely causes of the slowdown.The results show that although the CMIP6 models present some encouraging improvements when compared with CMIP5,most of them still fail to reproduce the warming slowdown.They considerably overestimate the warming rate observed in 1998–2013,exhibiting an obvious warming acceleration rather than the observed deceleration.This is probably associated with their deficiencies in simulating the distinct temperature change signals from the human-induced long-term warming trend and/or the three crucial natural variabilities at interannual,interdecadal,and multidecadal scales.In contrast,the 4 models that can successfully reproduce the slowdown show relatively high skills in simulating the long-term warming trend and the three keyscale natural variabilities.Our work may provide important insight for the simulation and prediction of near-term climate changes. | Meng WEI Qi SHU Zhenya SONG Yajuan SONG Xiaodan YANG Yongqing GUO Xinfang LI Fangli QIAO | 2021 | Science China Earth Sciences2021，64，6： | 5 |
| 20 | Microstructure and Tensile Properties of ZK60 Alloy Fabricated by Simplified Rapid Solidification Powder Metallurgy (S-RS P/M) Process显示文摘This study investigated the microstructures and mechanical properties of ZK60 alloy prepared by a simplified rapid solidification powder metallurgy (RS P/M) processing system (S-RS P/M), which consists of warm press in dry air and hot extrusion. Microstructure characterizations showed that S-RS P/M alloy consisted of magnesium matrix and oxide stringers of~1 μm in width. TEM (transmission electron microscopy) observations illustrated nano-size magnesia particles (10-30 nm) constituted oxide stringer in detail. Due to a relatively higher volume of nano-size magnesia particle produced during S-RS P/M process, 0.2% yield strength of S-RS P/M ZK60 alloy was found to be as high as 382 MPa, which is 10% higher than that of RS P/M alloy. The improvement in mechanical properties is mainly attributed to the combination effects of Orowan mechanism and coefficient of thermal expansion (CTE) mismatch because of the approximately same average grain size. | Zhenya Zhang, Huashun Yu , Shaoqing Wang, Haitao Wang and Guanghui Min Key Laboratory of Liquid Structure and Heredity of Materials, Ministry of Education, Shandong University, Jinan 250061, China | 2010 | Journal of Materials Science & Technology2010，26，2： | 5 |
