We report for the first time Tl isotope ratios ten geological reference materials (RMs), namely SGR‐1b (from USGS), and GBW07302, GBW07303a, GBW07401a, GBW03104, GBW07103, GBW07109, GBW07110, GBW07111 GBW07113 China). The principal matrix characteristics of these range from sediments to igneous rocks, including stream sediment, soil, shale, granite, nepheline syenite, trachyte, granodiorite rhyolite. Analytically, procedure we developed includes a sample digestion step, simplified...
We present two efficient chemical procedures to separate Zn from geological samples using single-stage column with AG1-X8 (100-200 mesh) for high-precision isotope ratio determination. These methods take advantage...
A single-stage column separation method based on an anion exchange resin is developed to purify Cd from geological and environmental materials for high-precision determination of isotopes by double spike MC-ICP-MS.
To evaluate the homogeneity of geological reference material BIR ‐1a (basalt; United States Geological Survey, USGS ) for Re‐Os isotopic studies at 0.2–1.0 g test portion size level, sixty‐three precise measurement results Re and Os mass fractions isotope amount ratios were obtained over an 18‐month period. These data reveal that has higher (0.691 ± 0.022 ng −1 , 2 s n = 63) lower (0.343 0.089 than UB ‐N (serpentinite, CRPG is homogeneous in 187 Os/ 188 ratio (0.13371 0.00092, level. The are...
A two-stage Cd purification method with anion exchange resin and BPHA extraction is developed to purify from geological materials for high precision determination of isotopic compositions by double spike MC-ICP-MS.
Determination of the Tl isotopic composition geological materials via MC-ICP-MS with mass bias corrected using external normalization.
This study reports an improved procedure for the simultaneous determination of Re–Os and S isotopic compositions sulfur-bearing minerals using negative thermal ionization mass spectrometry (N-TIMS) multicollector-inductively coupled plasma-mass (MC-ICP-MS), respectively.
Background Physical activity has been shown to have an effect on Carotid plaque (CP) which is a predictor of Cardiovascular disease (CVD). Studies that physical can alter the composition gut microbiota, whether its influence CP was mediated by microbiota yet be proved. Methods We conducted case–control study involving 30 patients and 31 controls. Logistic regression used analyze association between activity. LefSe explore as well CP, PhyloMed examine mediating in CP. Results After adjusting...
We are developing a novel imaging method that combines calcium and high-resolution adaptive-optics to study light responses of individual retinal ganglion cells in living macaque mouse eyes.
Abstract The seawater Molybdenum isotopic composition has been thought to have undergone little change over the Cenozoic Era, compared other redox sensitive isotope systems, such as Carbon and Sulfur. However, newly reconstructed Era δ 98/95 Mo values, based on analysis of a hydrogenic ferromanganese (Fe-Mn) crust obtained from Pacific Ocean, reveal significant decrease in values 2.80% at 53 Ma 2.34% 36.7 Ma. By utilizing steady-state mass balance model, we observed that primary factor...
Neural network based spectral mask estimation for acoustic beamforming, which consists of linear filtering and estimation, has shown to be a promising approach robust speech recognition in noisy environments. Nevertheless, few improvements are made on the filtering. In this paper, we investigate Speech Distortion Weighted Multichannel Wiener Filter (SDW-MWF) variable span filter, prove that they can linked by Generalized Eigenvalue Decomposition (GEVD) covariance matrix. The resulting GEVD...
