| 1 | Great flood in the middle-lower Yellow River reaches at 4000 a BP inferred from accurately-dated stalagmite records显示文摘Recently,Wu et al.[1]suggested an earthquake-induced landslide dam outburst flood on the eastern Tibetan Plateau at 1920BCE(3870 a BP,BP denotes year before 1950 CE)caused the Great Flood in the middle-lower Yellow River reaches,and resulted in the founding of Xia Dynasty at 3850 a BP.This age is$150–300younger than the previously estimated age of the Xia Dynasty[2].While the geological evidence of the outburst flood。 | Liangcheng Tan Chuan-Chou Shen Yanjun Cai Hai Cheng R.Lawrence Edwards | 2018 | Science Bulletin2018,63,4: | 16 |
| 2 | Diagnosabilities of exchanged hypercube networks under the pessimistic one-step diagnosis strategy显示文摘The exchanged hypercube EH(s, t)(where s≥1 and t ≥1) is obtained by systematically reducing links from a regular hypercube Qs+t+1. One-step diagnosis of exchanged hypercubes which involves only one testing phase during which processors test each other is discussed. The diagnosabilities of exchanged hypercubes are studied by using the pessimistic one-step diagnosis strategy under two kinds of diagnosis models: the PMC model and the M M*model. The main results presented here are the two proofs that the degree of diagnosability of the EH(s, t) under pessimistic one-step t1/t1 fault diagnosis strategy is 2s where1≤s≤t(respectively, 2t, where 1≤t≤s) based on the PMC model and that it is also 2s where 1≤s≤t(respectively, 2t,where 1≤t≤s) based on the M M*model. | Jiarong Liang Ying Huang Liangcheng Ye | 2015 | Journal of Systems Engineering and Electronics2015,26,2: | 12 |
| 3 | Application of Avaatech X-ray fluorescence core-scanning in Sr/Ca analysis of speleothems显示文摘Application of X-ray fluorescence core-scanning(XRF-CS) on both marine and lake sediments has achieved remarkable results. However, its application has not been widely extended to the research on speleothems. In this study, we measure the Sr abundance and the Sr/Ca ratios of three stalagmites(two aragonite stalagmites, one calcite stalagmite) using the state-of-the-art fourth-generation Avaatech high-resolution XRF core scanner. Through comparisons among different scan paths and among different scan resolutions, as well as comparisons with inductively coupled plasma optical emission spectrometer(ICP-OES), Itrax XRF, and Artax XRF results, we confirm that the Avaatech XRF core scanner could precisely, quickly, and nondestructively analyze the high-resolution Sr abundance of speleothems. Furthermore, we combine the stalagmite δ^(18)O records to explore the paleoclimatic significance of the measured stalagmite Sr/Ca. | Dong LI Liangcheng TAN Fei GUO Yanjun CAI Youbin SUN Gang XUE Xing CHENG Hong YAN Hai CHENG R.Lawrence EDWARDS Yongli GAO Jessica KELLEY | 2019 | Science China Earth Sciences2019,62,6: | 7 |
| 4 | The selection of a primary marker for the Anthropocene显示文摘Since Homo sapiens appeared,the planet has experienced continuing environmental changes[1,2].In 2000,Crutzen and Stoermer[3]systematically analysed the global changes caused by human activity over the previous 300 years and suggested that the Holocene epoch ended in the 1750s and a new geological age,the Anthropocene,began.Afterwards,the Anthropocene drew a lot of attention from both scientific community and the general public.The recognition and placement of the Anthropocene/Holocene boundary has been a subject of heated debates over the past two decades.At the 35th International Geological Congress(2016;IGC),the Anthropocene Working Group(AWG)recommended the Anthropocene to be formalised with an epoch rank,with the 1950s as its lower boundary[4]. | Tianli Wang Liangcheng Tan Hai Xu Jingjie Zang Dong Li Jianghu Lan Yongming Han Li Li | 2019 | Science Bulletin2019,64,22: | 4 |

| 8 | Dust storms in northern China during the last 500 years显示文摘The history and mechanisms of dust storms in northern China remain unclear owing to the paucity of reliable longterm,high-resolution geological records.In this study,we reconstructed the dust storm history of the last~500 years in northern China,based on sedimentary coarse fraction(>63μm)of a well-dated core from Lake Daihai,Inner Mongolia.The highresolution data reveal three intervals of frequent dust storms:AD 1520–1580,AD 1610–1720,and AD 1870–2000.The dust storm events in the Lake Daihai area were broadly synchronous with those inferred from other historical or geological records and generally occurred during cold intervals.Changes in the intensity of Siberian High and the westerlies modulated by temperature variations are the likely major factors controlling dust storm dynamics.An interesting feature is that although the intensities of dust storms have been systematically increased during the recent warming period,a clear decreasing trend within this period is evident.The recent increase in average dust storm intensity may be ascribed to an increase in particle supply resulting from a rapid increase in human activity,whereas the weakening trend was likely caused by decreases in average wind speed resulting from the recent global warming. | Shuang ZHANG Hai XU Jianghu LAN Yonaton GOLDSMITH Adi TORFSTEIN Guilin ZHANG Jin ZHANG Yunping SONG Kang’en ZHOU Liangcheng TAN Sheng XU Xiaomei XU Yehouda ENZEL | 2021 | Science China Earth Sciences2021,64,5: | 3 |
| 9 | Late Holocene hydroclimatic variations and possible forcing mechanisms over the eastern Central Asia显示文摘Hydroclimatic variations over the eastern Central Asia are highly sensitive to changes in hemispheric-scale atmospheric circulation systems. To fully understand the long-term variability and relationship between hydroclimate and atmospheric circulation system, we present a high-resolution lascustrine record of late Holocene hydroclimate from Lake Sayram, Central Tianshan Mountains, China, based on the total organic carbon, total nitrogen, and carbonate contents, carbon/nitrogen ratios, and grain size. Our results reveal four periods of substantially increased precipitation at the interval of 4000–3780, 3590–3210, 2800–2160, and 890–280 cal yr BP, and one period of slightly increased precipitation from 1700–1370 cal yr BP. These wetter periods broadly coincide with those identified in other records from the mid-latitude Westerlies-dominated eastern Central Asia, including the northern Tibetan Plateau. As such, a similar hydroclimatic pattern existed over this entire region during the late Holocene. Based on a close similarity of our record with reconstruction of North Atlantic Oscillation indices and solar irradiance, we propose that decreased solar irradiance and southern migration of the entire circum-North Atlantic circulation system, particularly the main pathway of the mid-latitude Westerlies, significantly influenced hydroclimate in eastern Central Asia during the late Holocene. Finally, the inferred precipitation at Lake Sayram has increased markedly over the past 100 years, although this potential future changes in hydroclimate in Central Asia need for further investigation. | Jianghu LAN Hai XU Keke YU Enguo SHENG Kangen ZHOU Tianli WANG YuANDa YE Dongna YAN Huixian WU Peng CHENG Waili ABULIEZI Liangcheng TAN | 2019 | Science China Earth Sciences2019,62,8: | 3 |
| 10 | Dynamic Load Identification in Time Domain显示文摘- In the time domain method the dynamic load is successfully identified when the accelerations, velocities and displacements or velocities and displacements of the structure are known. But in engineering practice or experiments usually only the acceleration response is recorded. In this paper an improved time domain method is proposed for dynamic load identification. In this method by using of Duhamel integral, only the acceleration response is required for load identification. As an application of the present method, the dynamic ice load on a Bohai offshore platform is identified based on some measured acceleration. The identified values of ice load are in good agreement with the measured ones. | Chu, Liangcheng Qu, Naisi Wu, Ruifeng Lu, Min Yang, Guojin | 1991 | China Ocean Engineering1991,6,3: | 3 |

| 13 | A high-sensitivity MEMS gravimeter with a largedynamic range显示文摘Precise measurement of variations in the local gravitational acceleration is valuable for natural hazard forecasting,prospecting,and geophysical studies.Common issues of the present gravimetry technologies include their high cost,high mass,and large volume,which can potentially be solved by micro-electromechanical-system(MEMS)technology.However,the reported MEMS gravimeter does not have a high sensitivity and a large dynamic range comparable with those of the present commercial gravimeters,lowering its practicability and ruling out worldwide deployment.In this paper,we introduce a more practical MEMS gravimeter that has a higher sensitivity of 8μGal/√Hz and a larger dynamic range of 8000 mGal by using an advanced suspension design and a customized optical displacement transducer.The proposed MEMS gravimeter has performed the co-site earth tides measurement with a commercial superconducting gravimeter GWR iGrav with the results showing a correlation coefficient of 0.91. | Shihao Tang Huafeng Liu Shitao Yan Xiaochao Xu Wenjie Wu Ji Fan Jinquan Liu Chenyuan Hu Liangcheng Tu | 2019 | Microsystems & Nanoengineering2019,5,1: | 2 |

| 15 | Aeolian dust dynamics in the Fergana Valley, Central Asia, since -30 ka inferred from loess deposits显示文摘Knowledge of the interactions among atmospheric dynamics,dust emissions and climate system is essential to understand the physical mechanisms for the dust lifecycle,their role in loess formation as well as the predictions of future dust concentration.However,these issues still remain relatively poorly known in Central Asia(CA).The extensive loess deposits on the CA pediments provide a promising archive to explore atmospheric dust dynamics and climatic conditions in the past and their association with loess formation.This study investigates the granulometric and magnetic properties of a loess section(named Osh section)in the Fergana Valley,which provides a sensitive record of atmospheric dust dynamics since 30 ka based on radiometric(AMS ^(14)C)dating.The frequency-dependent magnetic susceptibility(χfd)and the mean grain size are used to reconstruct the broadscale effective moisture and summer atmospheric dynamics pattern in CA,respectively.The results show that the precession forcing exerts a huge influence on the wind-regime variabilities in CA,but with different physical processes under the impact of the Northern Hemisphere ice sheet(NHIS)before and after 15 ka.The origin of the sedimentation rate variations in the Osh loess is also linked to the NHIS-modulated changes of the atmospheric circulation patterns.Either the strengthened westerlies or the increased surface roughness from higher vegetation cover in loess-deposition areas have significantly accelerated the loess accumulation.As a result,these complicated influence factors of sedimentation rate change in the Osh loess section,especially during the Holocene epoch,may hamper accessibility of the authentic dust emission flux and atmospheric dust concentration in CA. | Yue Li Yougui Song Dimitris G.Kaskaoutis Jinbo Zan Rustam Orozbaev Liangcheng Tan Xiuling Chen | 2021 | Geoscience Frontiers2021,12,5: | 1 |
