Hyperpolarized Noble Gas MR Imaging SNR comparison between 73.5 mT and 3 T in Rat Lung
Introduction In Hyperpolarized Noble Gas (HNG) MR imaging (i.e.Xe and He), the available magnetization is independent of magnetic field strength. Above a cut-off Larmor frequency when the sample (i.e. body) noise dominates the RF coil noise [1], the signal-to-noise ratio (SNR) is expected to decrease with field for band-matched imaging due to a reduction in the transverse relaxation time, T2* [...
متن کاملHow Do Brokers Broker? Tertius Gaudens, Tertius Iungens, and the Temporality of Structural Holes
Organizational network research has demonstrated that multiple benefits accrue to people occupying brokerage positions. However, the extant literature offers scant evidence of the process postulated to drive such benefits –information brokerage– and therefore leaves unaddressed the question of how brokers broker. We address this gap by examining the information-brokerage interactions in which a...
متن کاملFibularis Tertius Muscle: Cadaveric Study in Indians
Introduction: Fibularis tertius muscle (FTM) is a small, unipennate muscle of the anterior compartment of the leg which is peculiar to human [1]. Usually FTM is considered as a part of the extensor digitorum longus (EDL) muscle which arises Background: Fibularis tertius is a small, unipennate muscle of the anterior compartment of the leg which is peculiar to human. It is highly variable muscle....
متن کاملThe Education of Mr. T
U2 and U6 snRNAs pair to form a phylogenetically conserved complex at the catalytic core of the spliceosome. Interactions with divalent metal ions, particularly Mg(II), at specific sites are essential for its folding and catalytic activity. We used a novel Förster resonance energy transfer (FRET) method between site-bound luminescent lanthanide ions and a covalently attached fluorescent dye, co...
متن کاملExotic species with explicit noble metal-noble gas-noble metal linkages.
We present a study of the isoelectronic Pt2Ng2F4 and [Au2Ng2F4]2+ species with noble gas atoms (Ng = Kr, Xe, Rn) acting as links bridging the two noble metal atoms. The stability of the species is investigated using several thermodynamic, kinetic and reactivity indicators. The results are compared against [AuXe4]2+, which is thermodynamically unstable in the gas phase but is stabilized in the s...
