| 2 | Spatial correlation analysis of sea-bottom backscattering显示文摘The principle of the spatial correlation characteristics of sea-bottom backscattering was expounded.The Kirchhoff model is introduced to simulate sea-bottom backscattering and the spatial correlation is calculated.Some sediment characteristic parameters,such as the ratio of sediment mass density to water mass density,the ratio of sediment sound speed to water sound speed,the attenuation coefficient of sound waves,the strength and exponent of seabottom interface roughness spectrum,are considered while simulating and their influences on spatial correlation are analyzed.By establishing the expressions of the sediment characteristic parameters with the logarithmic sediment grain size,the variation tendency of the spatial correlation versus the logarithmic sediment grain size is obtained.The width of the major lobe of the spatial correlation function narrows as the logarithmic sediment grain size increases.The comparisons between simulated data and in-situ data collected in October 2007 have proven that their spatial correlation function waveforms agree well under the same sediment characteristics. | KUAI Duojie WANG Changhong FENG Lei WANG Yuling QIU Wei YI Huiqin CHEN Long | 2012 | Chinese Journal of Acoustics2012，31，3： | 9 |
| 3 | Alternations in the gut microbiota and metabolome with newly diagnosed unstable angina显示文摘Gut microbiota plays an important role in coronary heart disease, but its compositional and functional changes in unstable angina(UA) remain unexplored. We performed metagenomic sequencing of 133 newly diagnosed UA patients and 133 sex-and age-matched controls, and profiled the fecal and plasma metabolomes in 30 case-control pairs. The alpha diversity of gut microbiota was increased in UA patients:the adjusted odds ratios(ORs) per standard deviation increase in Shannon and Simpson indices were 1.30(95% confidence interval, 1.01-1.70) and 1.36(1.05-1.81), respectively. Two common species(depleted Klebsiella pneumoniae and enriched Streptococcus parasanguinis;P ≤ 0.002) and three rare species(depleted Weissella confusa, enriched Granulicatella adiacens and Erysipelotrichaceae bacterium 6_1_45;P ≤ 0.005) were associated with UA. The UA-associated gut microbiota was depleted in the pathway of Lphenylalanine degradation(P = 0.001), primarily contributed by Klebsiella pneumoniae. Consistently, we found increased circulating phenylalanine in UA patients(OR = 2.76 [1.17-8.16]). Moreover, Streptococcus parasanguinis was negatively correlated with fecal citrulline(Spearman's r_(s)=-0.470, P = 0.009), a metabolite depleted in UA patients(OR = 0.26 [0.08-0.63]). These findings are informative to help understand the metabolic connection between gut microbiota and UA. | Xuezhen Liu Miaoyan Shen Han Yan Pinpin Long Haijing Jiang Yizhi Zhang Lue Zhou Kuai Yu Gaokun Qiu Handong Yang Xiulou Li Xinwen Min Meian He Xiaomin Zhang Hyungwon Choi Chaolong Wang Tangchun Wu | 2022 | Journal of Genetics and Genomics2022，49，3： | 1 |
| 4 | Dispersion and support dictated properties and activities of Pt/metal oxide catalysts in heterogeneous CO oxidation显示文摘The source of activity of metal/metal oxides has always been an interesting,important but highly challenging research topic in heterogeneous catalysis.In CO oxidation reaction,this work clarifies dispersion and support dictated activities of Pt including single-atom(Pt1),2.8 nm(PtNP-S)and 36 nm(PtNP-L)Pt supported on both reducible TiO_(2) and“inert”Al_(2)O_(3) supports.The X-ray absorption fine structure(XAFS)shows that chemical state of Pt is affected by both dispersion and support:Pt1 presents fully oxidized state in both Pt1/TiO_(2) and Pt1/Al_(2)O_(3);PtNP-S in PtNP-S/TiO_(2) appear nearly oxidized state while about half of Pt is metallic state in PtNP-S/Al_(2)O_(3);PtNP-L in both PtNP-L/TiO_(2) and PtNP-L/Al_(2)O_(3) exhibit metallic state.All the Pt species supported on TiO_(2) present much lower apparent activation barriers(Eapp)than that on Al_(2)O_(3).Moreover,Pt1/TiO_(2) possesses dozen times of efficiency than PtNP-S/TiO_(2) although they have similar Eapp values.A truth is finally made clear that a reducible metal oxide with low oxygen vacancy formation energy is critical to endow Pt/metal oxide a high activity and the single-atom dispersion of Pt is the way to maximize the active sites of Pt/metal oxide. | Jiaojiao Song Yixuan Yang Shoujie Liu Lei Li Nan Yu Yuteng Fan Zhiming Chen Long Kuai Baoyou Geng | 2021 | Nano Research2021，14，12： | 1 |
