Introduction In recent years numerous approaches for the efficient, accurate and simultaneous quantitation of T1, T2, and M0 have been proposed – Ref 1 and 2 among them. Indeed, growing interest in generating synthetic MR images [2] and in “quantitative” tissue characterization continues to drive technical developments in MR relaxometry. Here we propose a novel 2D multi-slice pulse sequence tha...

Ground-based counts and colors of faint galaxies in the U and R bands in one field at high Galactic latitude are presented. Integrated over flux, a total of 1.2 × 10 sources per square degree are found to U = 25.5 mag and 6.3 × 10 sources per square degree to R = 27 mag, with d logN/dm ∼ 0.5 in the U band and d logN/dm ∼ 0.3 in the R band. Consistent with these number-magnitude curves, sources ...

The present study aimed to investigate the therapeutic effect of monoammonium glycyrrhizinate (MAG) on lipopolysaccharide- (LPS-) induced acute lung injury (ALI) in mice and possible mechanism. Acute lung injury was induced in BALB/c mice by intratracheal instillation of LPS, and MAG was injected intraperitoneally 1 h prior to LPS administration. After ALI, the histopathology of lungs, lung wet...

The MACHO Project is a microlensing survey that monitors the brightnesses of ∼60 million stars in the Large Magellanic Cloud (LMC), Small Magellanic Cloud, and Galactic bulge. Our database presently contains about 80 billion photometric measurements, a significant fraction of all astronomical photometry. We describe the calibration of MACHO two-color photometry and transformation to the standar...

We show that the luminosity dependence of the red clump stars on age and metallicity can cause a difference of up to ∼ <0.6 mag in the mean absolute I magnitude of the red clump between different stellar populations. We show that this effect may resolve the apparent ≈0.4 mag discrepancy between red clump-derived distance moduli to the Magellanic Clouds and those from, e.g., Cepheid variables. T...

We test and analyze an existing statistical typing method, and further apply that method to construct a luminosity functions which covers stars down to a luminosity of 16.0 mag. These methods are implemented on data sets collected using the near-infrared integral field spectrograph OSIRIS on Keck II. Previously, the data has allowed for separation of early-type stars (∼4-6 Myr) from late-type s...
