Rotationally Cold OH^{-} Ions in the Cryogenic Electrostatic Ion-Beam Storage Ring DESIREE.

Physical review letters

Schmidt HT, Eklund G, Chartkunchand KC, Anderson EK, Kamińska M, de Ruette N, Thomas RD, Kristiansson MK, Gatchell M, Reinhed P, Rosén S, Simonsson A, Källberg A, Löfgren P, Mannervik S, Zettergren H, Cederquist H.
PMID: 28949695
Phys Rev Lett. 2017 Aug 18;119(7):073001. doi: 10.1103/PhysRevLett.119.073001. Epub 2017 Aug 14.

We apply near-threshold laser photodetachment to characterize the rotational quantum level distribution of OH^{-} ions stored in the cryogenic ion-beam storage ring DESIREE at Stockholm University. We find that the stored ions relax to a rotational temperature of 13.4±0.2...

Moraxella catarrhalis is a Gram-negative commensal and pathogenic bacterium found in the human respiratory tract. It is associated with otitis media and respiratory tract infections. Here, we report the draft genome sequence of M. catarrhalis type strain CCUG 353(T),...

Resistance Mutations in gyrA and parC are Common in Escherichia Communities of both Fluoroquinolone-Polluted and Uncontaminated Aquatic Environments.

Front Microbiol. 2015 Dec 09;6:1355. doi: 10.3389/fmicb.2015.01355. eCollection 2015.

Alterations in the target proteins of fluoroquinolones, especially in GyrA and ParC, are known to cause resistance. Here, we investigated environmental Escherichia communities to explore the possible link between the abundance of mutations, and the exposure to fluoroquinolones. Sediment...

Personality traits are major determinants of social behavior influencing various diseases including addiction. Twin and family studies suggest personality and addiction to be under genetic influence. Identification of DNA susceptibility variants relies on valid and reliable phenotyping approaches. We...
