| 2 | Multi-scale spatial relationships between soil total nitrogen and influencing factors in a basin landscape based on multivariate empirical mode decomposition显示文摘The relationships between soil total nitrogen(STN)and influencing factors are scale-dependent.The objective of this study was to identify the multi-scale spatial relationships of STN with selected environmental factors(elevation,slope and topographic wetness index),intrinsic soil factors(soil bulk density,sand content,silt content,and clay content)and combined environmental factors(including the first two principal components(PC1 and PC2)of the Vis-NIR soil spectra)along three sampling transects located at the upstream,midstream and downstream of Taiyuan Basin on the Chinese Loess Plateau.We separated the multivariate data series of STN and influencing factors at each transect into six intrinsic mode functions(IMFs)and one residue by multivariate empirical mode decomposition(MEMD).Meanwhile,we obtained the predicted equations of STN based on MEMD by stepwise multiple linear regression(SMLR).The results indicated that the dominant scales of explained variance in STN were at scale 995 m for transect 1,at scales 956 and 8852 m for transect 2,and at scales 972,5716 and 12,317 m for transect 3.Multi-scale correlation coefficients between STN and influencing factors were less significant in transect 3 than in transects 1 and 2.The goodness of fit root mean square error(RMSE),normalized root mean square error(NRMSE),and coefficient of determination(R2)indicated that the prediction of STN at the sampling scale by summing all of the predicted IMFs and residue was more accurate than that by SMLR directly.Therefore,the multi-scale method of MEMD has a good potential in characterizing the multi-scale spatial relationships between STN and influencing factors at the basin landscape scale. | ZHU Hongfen CAO Yi JING Yaodong LIU Geng BI Rutian YANG Wude | 2019 | Journal of Arid Land2019，11，3： | 0 |
| 3 | Survival in the Marginalized World-An Existential Analysis of The Well by Elizabeth Jolley显示文摘Taking The Well,written by Australian novelist Elizabeth Jolley,as the research object,this paper aims to clarify the complex disputes between the protagonists and applies existentialism theory to analyze the dilemma confronted by the protagonists,the relationship between self and other,existence and free choice,which causes people to ponder deeply over how marginalized people should exist in the human world and find the access to the meaning of existence,so as to appeal the social care for those at the margins. | PAN Hongfen YANG Yongchun | 2022 | US-China Foreign Language2022，20，2： | 0 |
| 4 | Effect of digit ratio on contact heat evoked potentials in China显示文摘To the Editor:Contact heat evoked potentials(CHEPs)has become an important electrophysiologic diagnostic approach for small fiber neuropathy,[1]which is characterized by involvement of myelinated Aδand unmyelinated C fibers as a result of various etiologies.[1,2]CHEPs are affected by gender,age,body height,and so on.[1,2]The effect of the second to fourth(2D:4D)digit ratio on CHEP parameters has not been investigated.Digit ratio is defined as the length of the index finger dividing the length of the ring finger,which is smaller in men than in women.[3]We aimed to find out whether digit ratio has any role influencing CHEPs,and to strengthen the understanding and improve the methodology of CHEPs. | Bo Sun Hongfen Wang Zhengqing He Xusheng Huang Zhaohui Chen Fei Yang | 2022 | Chinese Medical Journal2022，，4： | 0 |
| 5 | Gold nanoparticle-decorated MoSe_(2) nanosheets as highly effective peroxidase-like nanozymes for total antioxidant capacity assay显示文摘A visual colorimetric detection strategy is reported for total antioxidant capacity(TAC)assay by using 3,3',5,5'-tetramethylbenzidine(TMB)oxidation as chromogenic substrate based on gold nanoparticle-decorated MoSe_(2) nanosheets(Au@MoSe_(2)).Au@MoSe_(2) nanostructures exhibit high peroxidase-like activity and can catalyze H_(2)O_(2)to oxidize TMB.Based on inhibition effect of ascorbic acid(AA)on TMB oxidation,a facile and sensitive colorimetric method was developed for AA detection.Under optimal conditions,the proposed method showed a sensitivity for AA in a concentration range from 2 to 120μM and limit of detection was 0.41μM.Furthermore,the method was employed for TAC assay in actual samples,including commercial beverages and vitamin C tablets.This work represents a model in nanostructure design and will lead to further development of TAC assay in evaluation of antioxidant food quality. | Chengyi Hong Lingling Chen Jiayi Huang Yunling Shen Hongfen Yang Zhiyong Huang Ren Cai Weihong Tan | 2023 | Nano Research2023，16，5： | 0 |
