The ion–molecule reactions in pure nitrogen and nitrogen containing traces of water were
studied with a pulsed electron‐beam mass spectrometer having a field‐free high‐pressure …

The formation of H + (H 2 O) n clusters in moist oxygen is of interest since this process must
occur in the troposphere and has been observed to occur in the D region of the ionosphere. …

Purpose As MR scanner hardware has improved, allowing for increased gradient strengths,
we are able to generate higher b values for diffusion-weighted (DW) imaging. Our purpose …

Two series of drugs, the aliphatic-N-methyl propargylamines and the aliphatic propargylamines,
have been synthesised and shown to be specific, irreversible, and potent monoamine …

The Chequamegon Heterogeneous Ecosystem Energy-Balance Study Enabled by a High-Density
Extensive Array of Detectors 2019 (CHEESEHEAD19) is an ongoing National …

Avermectin endectocides are used for the treatment of cattle against a variety of nematode
and arthropod parasites, and consequently may appear in milk after normal or off-label use. …

Stereospecific replacement of deuterium in the α-carbon side chain position of dopamine (DA)
was achieved by decarboxylation of l-3,4-dihydroxyphenylalanine (l-dopa) using hog …

The highly interactive and variable nature of scales of space and time featured in components
of the Earth system imparts enormous complexity to land‐atmosphere interactions. Here, …

A mass spectrometer for high‐pressure ion–molecule reaction studies was constructed using
a pulsed 4‐keV electron beam and pulsed “gate‐open” mass‐spectrometer detection. The …

Computed tomography (CT) and magnetic resonance (MR) imaging are used routinely to
stage skull base neoplasms preoperatively, define the extent of the tumor, identify perineural …
