| 1 | Nataf transformation based point estimate method显示文摘Structural probabilistic analysis quantifies the effect of input random variables, such as material proper- ties, geometrical parameters and loading conditions, on the structural responses. The point estimate method (PEM) is a direct and easy-used way to perform the structural probabilistic analysis in practice. In this paper, a novel and efficient point estimate method is proposed for computing the first four statistical moments of structural response which is a function of input random variables. The method adopts Nataf transformation to replace Rosenblatt transformation in conventional point estimate method. Because of the nature of engineering problems and limited statistical data, the joint probability density function (PDF) of all input random variables is hard to acquire, but it must be known in Rosenblatt transformation. A more common case is that the marginal PDF of each random variable and the correlation matrix are available, which just satisfy the service condition of Nataf transformation. Hence the Nataf transformation based point estimate method is particularly suitable for engineering applications. The comparison between the proposed method and the conventional point estimate method shows that (1) they are equivalent when all random variables are mutually independent; (2) if the marginal PDFs and the correlation matrix are known, the conventional PEM cannot be applicable, but the proposed method can give a rational approximation. Finally, the procedure is demonstrated in detail through a simple illustration. | LI HongShuang LU ZhenZhou YUAN XiuKai | 2008 | Chinese Science Bulletin2008，53，17： | 34 |
| 2 | Climatology and seasonal variability of satellite-derived chlorophyll a around the Shandong Peninsula显示文摘The chlorophyll a(Chl a)is an important indicator of marine ecosystems.The spatiotemporal variation of the Chl a greatly aff ects the mariculture and marine ranching in coastal waters of the Shandong Peninsula.In the current study,the climatology and seasonal variability of surface Chl-a concentration around the Shandong Peninsula are investigated based on 16 years(December 2002-November 2018)of satellite observations.The results indicate that the annual mean Chl-a concentration is greater in the Bohai Sea than in the Yellow Sea and decreases from coastal waters to off shore waters.The highest Chl-a concentrations are found in Laizhou Bay(4.2-8.0 mg/m^(3)),Haizhou Bay(4.2-5.9 mg/m^(3))and the northeast coast of the Shandong Peninsula(4.4-5.0 mg/m^(3)),resulting from the combined eff ects of the intense riverine input and long residence time caused by the concave shape of the coastline.The seasonal Chl-a concentration shows a significant spatial variation.The Chl-a concentrations in these three subregions generally exhibit an annual maximum in August/September,due to the combined eff ects of sea surface temperature,river discharge and sea surface wind.In the southeast coast region,however,the Chl-a concentration is lowest throughout the year and reaches a maximum in February with a minimum in July,forced by the seasonal evolution of the Yellow Sea Cold Water and monsoon winds.The interannual Chl-a concentration trends vary among regions and seasons.There are significant increasing trends over a large area around Haizhou Bay from winter to summer,which are mainly caused by the rising sea surface temperature and eutrophication.In other coastal areas,the Chl-a concentration shows decreasing trends,which are clearest in summer and induced by the weakening land rainfall.This study highlights the differences in the Chl-a dynamics among regions around the Shandong Peninsula and is helpful for further studies of coupled physical-ecological-human interactions at multiple scales. | Xiukai SONG Yanzhen GU Fangguo ZHAI Peiliang LI Pengxia LIU Zizhou LIU Wenfan WU Yaozu CHEN Xiangyang JIANG Jianlong HE | 2021 | Journal of Oceanology and Limnology2021，39，4： | 3 |

| 4 | An atlas of CNV maps in cattle, goat and sheep显示文摘Copy number variation(CNV)is the most prevalent type of genetic structural variation that has been recognized as an important source of phenotypic variation in humans,animals and plants.However,the mechanisms underlying the evolution of CNVs and their function in natural or artificial selection remain unknown.Here,we generated CNV region(CNVR)datasets which were diverged or shared among cattle,goat,and sheep,including 886 individuals from 171 diverse populations.Using 9 environmental factors for genome-wide association study(GWAS),we identified a series of candidate CNVRs,including genes relating to immunity,tick resistance,multi-drug resistance,and muscle development.The number of CNVRs shared between species is significantly higher than expected(P<0.00001),and these CNVRs may be more persist than the single nucleotide polymorphisms(SNPs)shared between species.We also identified genomic regions under long-term balancing selection and uncovered the potential diversity of the selected CNVRs close to the important functional genes.This study provides the evidence that balancing selection might be more common in mammals than previously considered,and might play an important role in the daily activities of these ruminant species. | Yongzhen Huang Yunjia Li Xihong Wang Jiantao Yu Yudong Cai Zhuqing Zheng Ran Li Shunjin Zhang Ningbo Chen Hojjat Asadollahpour Nanaei Quratulain Hanif Qiuming Chen Weiwei Fu Chao Li Xiukai Cao Guangxian Zhou Shudong Liu Sangang He Wenrong Li Yulin Chen Hong Chen Chuzhao Lei Mingjun Liu Yu Jiang | 2021 | Science China(Life Sciences)2021，64，10： | 2 |

| 15 | The influence of water-sediment regulation on macrobenthic community structures in the Huanghe River(Yellow River)Estuary during 2012–2016显示文摘To determine if water-sediment regulation has affected macrobenthic community structure in the Huanghe River Estuary,China,macrobenthic samples were collected following regulation events from 2012 to 2016.We identify seven phyla and 138 macrobenthic species from within samples throughout the survey area,over time.Species richness and abundance in 2012 were significantly higher than in 2016.Biomass did not differ significantly during 2012–2016.Dominant species were mostly small polychaetes,with mollusks,arthropods,and echinoderms all being relatively rare.In 2016,dominant species were small polychaetes.MDS reveals macrobenthic communities at all surveyed distances from the estuary to have become the same community structure over time.Shannon-Wiener diversity and Margalef richness indexes trended down over time.CCA reveals the most dominant sediment-dwelling species to prefer lower dissolved oxygen,sulfides,and pH,and sediments with high D50 and low clay content.We speculate that water-sediment regulation has affected seabed communities,particularly Region A in our survey area. | Shaowen Li Fan Li Xiukai Song Mingliang Zhang | 2020 | Acta Oceanologica Sinica2020，39，10： | 1 |
| 16 | Oscillation of current-induced interfacial spins reorientation in a like-synthetic antiferromagnet/antiferromagnet system显示文摘Antiferromagnets have been attracting tremendous interest in the spintronics community due to their intrinsic appealing properties,such as zero stray field and ultrafast spin dynamics.Recently,the electrical manipulation of bulk properties of antiferromagnets has been widely studied,but exploring the use of antiferromagnetic(AFM)interfacial properties to investigate some key issues in spintronic devices is urgently desired.In this study,the magnetic and spin transport properties mediated by interlayer exchange coupling(IEC)are examined through spin-orbit torque(SOT)-induced tunability of interfacial spins in heavy-metal/like-synthetic antiferromagnet/antiferromagnet heterostructure devices.We found that the exchange bias and coercivity and the critical current density for SOT switching can be modulated by IEC,associating with the oscillation of SOTinduced interfacial spins reorientation at zero field,which can be well understood with the modified Ruderman-Kittel-KasuyaYosida model.Our finding opens a new route for understanding and using the AFM interfacial spins in spintronics. | XiongHua Liu YongCheng Deng XiuKai Lan RunZe Li KaiYou Wang | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，6： | 0 |
