| 2 | Assessment of coral bleaching using symbiotic zooxanthellae density and satellite remote sensing data in the Nansha Islands,South China Sea显示文摘Coral bleaching,characterized by a significant loss of symbiotic zooxanthellae,is the primary cause of mass coral mortality and reef degradation throughout the world.The characteristics,processes,and resistance of corals to bleaching varies significantly and is dependent on environmental conditions.We documented a mass coral bleaching event in June 2007 at the Meiji and Zhubi Reefs,Nansha Islands (NS),South China Sea using ecological surveys and measurement of coral zooxanthellae density and sea surface temperatures (SST).More than 35 species of corals (between 0-20 m in depth) were bleached.These bleached corals accounted for 15.6% of total corals in the investigated quadrats.The branching corals Pocillopora and Acropora were the most vulnerable species whereas the massive corals Porites and Favia were more tolerant of the high SSTs.Surprisingly,we found no evidence of bleaching in Agariciidae corals suggesting that this family is resistant to thermal stresses.The bleached corals had lost 72%-90% of their symbiotic zooxanthellae.Furthermore,corals that had no visual signs of bleaching had also lost 31%-53% of their zooxanthellae suggesting that most corals were experiencing the early stage of bleaching.The monthly mean SST during June 2007 was 30.8°C,the highest since 1998.Based on measurements of SST and the Hotspots and DHW data (NOAA),we conclude that it the extremely high SSTs triggered this coral bleaching event.Our results suggest that the previously accepted temperature thresholds used to predict coral bleaching based on satellite data are likely to underestimate the extent and intensity of coral bleaching,at least in the NS. | LI Shu,YU KeFu,CHEN TianRan,SHI Qi & ZHANG HuiLing CAS Key Laboratory of Marginal Sea Geology,South China Sea Institute of Oceanology,Chinese Academy of Sciences Guangzhou 510301,China | 2011 | Chinese Science Bulletin2011，56，10： | 15 |

| 7 | Magnetohydrodynamics (MHD) numerical simulations on the interaction of the solar wind with the magnetosphere: A review显示文摘The magnetosphere is the outermost layer of the geospace, and the interaction of the solar wind with the magnetosphere is the key element of the space weather cause-and-effect chain process from the Sun to Earth, which is one of the most challenging scientific problems in the geospace weather study. The nonlinearity, multiple component, and time-dependent nature of the geospace make it very difficult to describe the physical process in geospace using traditional analytic analysis approach. Numerical simulations, a new research tool developed in recent decades, have a deep impact on the theory and application of the geospace. MHD simulations started at the end of the 1970s, and the initial study was limited to two-dimensional (2D) cases. Due to the intrinsic three-dimensional (3D) characteristics of the geospace, 3D MHD simulations emerged in the 1980s, in an attempt to model the large-scale structures and fundamental physical processes in the magnetosphere. They started to combine with the space exploration missions in the 1990s and make comparisons with observations. Physics-based space weather forecast models started to be developed in the 21st century. Currently only a few space-power countries such as USA and Japan have developed 3D magnetospheric MHD models. With the rapid advance of space science in China, we have developed a new global MHD model, namely PPMLR-MHD, which has high order spatial accuracy and low numerical dissipation. In this review, we will briefly introduce the global 3D MHD modeling, especially the PPMLR-MHD code, and summarize our recent work based on the PPMLR-MHD model, with an emphasis on the interaction of interplanetary shocks with the magnetosphere, large-scale current systems, reconnection voltage and transpolar potential drop, and Kelvin-Helmholtz (K-H) instability at the magnetopause. | WANG Chi GUO XiaoCheng PENG Zhong TANG BinBin SUN TianRan LI WenYa HU YouQiu | 2013 | Science China Earth Sciences2013，56，7： | 10 |

| 10 | Exploitation of Bi2O2Se/graphene van der Waals heterojunction for creating efficient photodetectors and short-channel field-effect transistors显示文摘The formation of heterojunction within solid-state devices enables them with eventually high performances,but provides a challenge for material synthesis and device fabrication because strict conditions such as lattice match are needed.Herein,we show a facile method to fabricate a van der Waals(vdW)heterojunction between two-dimensional(2D)bismuth oxyselenide(Bi2O2Se)and graphene,during which the graphene is directly transferred to the Bi2O2Se and served as a lowcontract-resistant electrode with small work function mismatch(~50 meV).As an optoelectronic device,the Bi2O2Se/graphene vdW heterojunction allows for the efficient sensing toward 1200-nm incident laser.Regarding the application of fieldeffect transistors(FETs),the short-channel(50 nm)sample can be synthesized by utilizing these two 2D materials(ie,channel:Bi2O2Se;drain/source terminal:graphene)and the n-type characteristic can be observed with the accordant field modulation.It is confirmed that we show a simple way to prepare the vdW heterojunction which is aiming to the high-performance applications among optoelectronics and FETs. | Congwei Tan Shipu Xu Zhenjun Tan Luzhao Sun Jinxiong Wu Tianran Li Hailin Peng | 2019 | InfoMat2019，1，3： | 8 |
| 11 | Hierarchical resource allocation for integrated modular avionics systems显示文摘Recently the integrated modular avionics(IMA) architecture which introduces the concept of resource partitioning becomes popular as an alternative to the traditional federated architecture.A novel hierarchical approach is proposed to solve the resource allocation problem for IMA systems in distributed environments.Firstly,the worst case response time of tasks with arbitrary deadlines is analyzed for the two-level scheduler.Then,the hierarchical resource allocation approach is presented in two levels.At the platform level,a task assignment algorithm based on genetic simulated annealing(GSA) is proposed to assign a set of pre-defined tasks to different processing nodes in the form of task groups,so that resources can be allocated as partitions and mapped to task groups.While yielding to all the resource constraints,the algorithm tries to find an optimal task assignment with minimized communication costs and balanced work load.At the node level,partition parameters are optimized,so that the computational resource can be allocated further.An example is shown to illustrate the hierarchal resource allocation approach and manifest the validity.Simulation results comparing the performance of the proposed GSA with that of traditional genetic algorithms are presented in the context of task assignment in IMA systems. | Tianran Zhou Huagang Xiong Zhen Zhang | 2011 | Journal of Systems Engineering and Electronics2011，22，5： | 7 |
| 12 | Estimate of carbonate production by scleractinian corals at Luhuitou fringing reef,Sanya,China显示文摘Carbonate production by scleractinian corals not only maintains coral reef growth, but also represents an important source of atmospheric carbon dioxide. In this paper the carbonate production by scler-actinian corals at Luhuitou fringing reef, Sanya, Hainan Island, China, is investigated with an ecological census-based method. Averaged carbonate production is 1.16 ± 0.55 kg·m-2·a-1 and 3.52 ± 1.32 kg·m-2·a-1 on the reef flat and reef slope, respectively, depending on the composition and distribution of corals and the intergeneric difference of skeletal growth. In response to the rapidly increasing human impacts, coral carbonate production has decreased by 80%―89% at this fringing reef since the 1960s; as a result, the reef accretion rate declined and became lower than the rate of sea level rise. Further development of the Luhuitou fringing reef will switch significantly from lateral extension sea-wards to vertical growth, reflecting a response of coral reef biogeomorphic process to strong human impacts under the background of global sea level rise. In addition, decrease in coral carbonate production reduced CO2 release from this fringing reef. In the future, it is likely that the role played by coral reefs, especially of fringing reefs, in the ocean and even in the global carbon cycle will be modified or weakened by the increasing human impacts. | SHI Qi ZHAO MeiXia ZHANG QiaoMin YU KeFu CHEN TianRan LI Shu WANG HanKui | 2009 | Chinese Science Bulletin2009，54，4： | 7 |

| 16 | Construction of a small-caliber tissue-engineered blood vessel using icariin-loaded β-cyclodextrin sulfate for in situ anticoagulation and endothelialization显示文摘The rapid endothelialization of tissue-engineered blood vessels(TEBVs) can effectively prevent thrombosis and inhibit intimal hyperplasia. The traditional Chinese medicine ingredient icariin is highly promising for the treatment of cardiovascular diseases.β-cyclodextrin sulfate is a type of hollow molecule that has good biocompatibility and anticoagulation properties and exhibits a sustained release of icariin. We studied whether icariin-loaded β-cyclodextrin sulfate can promote the endothelialization of TEBVs. The experimental results showed that icariin could significantly promote the proliferation and migration of endothelial progenitor cells; at the same time, icariin could promote the migration of rat vascular endothelial cells(RAVECs). Subsequently,we used an electrostatic force to modify the surface of the TEBVs with icariin-loaded β-cyclodextrin sulfate, and these vessels were implanted into the rat common carotid artery. After 3 months, micro-CT results showed that the TEBVs modified using icariin-loaded β-cyclodextrin sulfate had a greater patency rate. Scanning electron microscopy(SEM) and CD31 immunofluorescence results showed a better degree of endothelialization. Taken together, icariin-loaded β-cyclodextrin sulfate can achieve anticoagulation and rapid endothelialization of TEBVs to ensure their long-term patency. | Jingyuan Yang Keyu Wei Yeqin Wang Yanzhao Li Ning Ding Da Huo Tianran Wang Guanyuan Yang Mingcan Yang Tan Ju Wen Zeng Chuhong Zhu | 2018 | Science China(Life Sciences)2018，61，10： | 5 |
| 17 | A Lunar-based Soft X-ray Imager(LSXI)for the Earth's magnetosphere显示文摘We propose to use the Moon as a platform to obtain a global view of Earth's magnetosphere by a Lunar-based Soft X-ray Imager(LSXI).LSXI is a wide field-of-view Soft X-ray telescope,which can obtain X-ray images of Earth's magnetosphere based on the solar wind charge exchange(SWCX)X-ray emission.Global perspective is crucial to understand the overall interaction of the solar wind with magnetosphere.LSXI is capable of continuously monitoring the evolution of geospace conditions under the impact of the solar wind by simultaneous observation of the bow shock,magnetosheath,magnetopause and cusps for the first time.This proposal is answering the call for the Chinese Lunar Exploration Program Phase IV. | Yihong GUO Chi WANG Fei WEI Tianran SUN Xizheng YU Songwu PENG Graziella BRANDUARDI-RAYMONT Steven SEMBAY | 2021 | Science China Earth Sciences2021，64，7： | 5 |
| 18 | Direct generation of watt-level yellow Dy^(3+)-doped fiber laser显示文摘Yellow lasers(∼565–590 nm)are of tremendous interest in biomedicine,astronomy,spectroscopy,and display technology.So far,yellow lasers still have relied heavily on nonlinear frequency conversion of near-infrared lasers,precluding compact and low-cost yellow laser systems.Here,we address the challenge through demonstrating,for the first time,to the best of our knowledge,watt-level high-power yellow laser generation directly from a compact fiber laser.The yellow fiber laser simply consists of a Dy^(3+)-doped ZBLAN fiber as gain medium,a fiber end-facet mirror with high reflectivity at yellow and a 450-nm diode laser as the pump source.We comprehensively investigated the dependence of the yellow laser performance on the output coupler reflectivity and the gain fiber length and demonstrated that the yellow fiber laser with an output coupler reflectivity of 4% and a gain fiber length of∼1.8 m yields a maximum efficiency of 33.6%.A maximum output power of 1.12 W at 575 nm was achieved at a pump power of 4.20 W.This work demonstrated the power scaling of yellow Dy^(3+)-doped ZBLAN fiber lasers,showing their promise for applications in ophthalmology,astronomical exploration,and high-resolution spectroscopy. | Jinhai Zou Tianran Li Yanbo Dou Jin Li Nan Chen Yikun Bu Zhengqian Luo | 2021 | Photonics Research2021，9，4： | 5 |
| 19 | The Soft X-ray Imager(SXI)on the SMILE Mission显示文摘The Soft X-ray Imager(SXI)is part of the scientific payload of the Solar wind Magnetosphere Ionosphere Link Explorer(SMILE)mission.SMILE is a joint science mission between the European Space Agency(ESA)and the Chinese Academy of Sciences(CAS)and is due for launch in 2025.SXI is a compact X-ray telescope with a wide field-of-view(FOV)capable of encompassing large portions of Earth’s magnetosphere from the vantage point of the SMILE orbit.SXI is sensitive to the soft X-rays produced by the Solar Wind Charge eXchange(SWCX)process produced when heavy ions of solar wind origin interact with neutral particles in Earth’s exosphere.SWCX provides a mechanism for boundary detection within the magnetosphere,such as the position of Earth’s magnetopause,because the solar wind heavy ions have a very low density in regions of closed magnetic field lines.The sensitivity of the SXI is such that it can potentially track movements of the magnetopause on timescales of a few minutes and the orbit of SMILE will enable such movements to be tracked for segments lasting many hours.SXI is led by the University of Leicester in the United Kingdom(UK)with collaborating organisations on hardware,software and science support within the UK,Europe,China and the United States. | S.Sembay A.L.Alme D.Agnolon T.Arnold A.Beardmore A.Belén Balado Margeli C.Bicknell C.Bouldin G.Branduardi-Raymont T.Crawford J.P.Breuer T.Buggey G.Butcher R.Canchal J.A.Carter A.Cheney Y.Collado-Vega H.Connor T.Crawford N.Eaton C.Feldman C.Forsyth T.Frantzen G.Galgóczi J.Garcia G.Y.Genov C.Gordillo H-P.Gröbelbauer M.Guedel Y.Guo M.Hailey D.Hall R.Hampson J.Hasiba O.Hetherington A.Holland S-Y.Hsieh M.W.J.Hubbard H.Jeszenszky M.Jones T.Kennedy K.Koch-Mehrin S.Kögl S.Krucker K.D.Kuntz C.Lakin G.Laky O.Lylund A.Martindale J.Miguel Mas Hesse R.Nakamura K.Oksavik N.Østgaard H.Ottacher R.Ottensamer C.Pagani S.Parsons P.Patel J.Pearson G.Peikert F.S.Porter T.Pouliantis B.H.Qureshi W.Raab G.Randal A.M.Read N.M.M.Roque M.E.Rostad C.Runciman S.Sachdev A.Samsonov M.Soman D.Sibeck S.Smit J.Søndergaard R.Speight S.Stavland M.Steller TianRan Sun J.Thornhill W.Thomas K.Ullaland B.Walsh D.Walton C.Wang S.Yang | 2024 | Earth and Planetary Physics2024，8，1： | 4 |
| 20 | Deriving the magnetopause position from wide field-of-view soft X-ray imager simulation显示文摘Imaging techniques provide essential information in astronomical and space physics studies.The Soft X-ray Imager(SXI)will obtain images of the Earth’s magnetosphere via the solar wind charge exchange process in a global view.However,it is a challenge to reconstruct its 3-D structures from the observed 2-D image(s).In this paper,a recently proposed method,Tangent Fitting Approach(TFA),is validated to reconstruct the large-scale magnetopause from a single X-ray image obtained by instrument simulation.It is revealed that the large-scale magnetopause under a medium solar wind number density can be well reconstructed,although the locations of maximum X-ray photon counts are scattered in the image due to instrumental effects and diffusive sky background.Higher solar wind number density leads to stronger signals and further leads to better reconstruction results.For lower solar wind density,the X-ray maximum photon counts may not be identified from the SXI simulations,preprocessing of the images shall be considered before applying TFA.Furthermore,the subsolar magnetopause can be well derived when the satellite is on the dayside orbits. | Yihong GUO Tianran SUN Chi WANG Steven SEMBAY | 2022 | Science China Earth Sciences2022，65，8： | 4 |
