Introduction The sediments of the Yellow River delta record environmental changes in basin on a long time scale and are sensitive to river diversion sedimentary environment evolution. Methods In this study, cores YDC YDG near estuary since 1976 were taken as research object, parameterized end-member analysis model was used analyze grain-size data cores. Results results show that: main silty san...

VopL and VopF (VopL/F) are tandem WH2-domain actin assembly factors used by infectious Vibrio species to induce actin assembly in host cells. There is disagreement about the filament assembly mechanism of VopL/F, including whether they associate with the filament barbed or pointed end. Here, we used multicolor total internal reflection fluorescence microscopy to directly observe actin assembly ...

A compilation of Fe-bearing chlorite analyses is used: (1) to investigate the Alfree di-trioctahedral (AFDT) substitution 2Fe +□ = 3(Mg,Fe) in chlorite; and (2) to estimate the composition of a ferri-sudoite end-member (Si3Al)[(Fe ,Mg)2Fe 3+ 2 □Al]O10(OH)8 within the chlorite solid-solution domain. According to our observations, up to two Fe cations might be allocated in the M2-M3 chlorite site...
