Recovery rates from Middlebrook 7H11-selective 7H11 biplates and Lowenstein-Jensen slants (LJ) used with BACTEC 12B vials were compared for 5,399 specimens. For 578 specimens that were inoculated onto three media, 580 mycobacteria were isolated, including 277 (48%) Mycobacterium avium complex isolates, 230 (40%) Mycobacterium tuberculosis isolates, and 73 (12%) other mycobacteria. For BACTEC 12...

We present a HST WFC3 transmission spectrum for the transiting exoplanet HAT-P-12b. This warm (1000 K) sub-Saturn-mass planet has a smaller mass and a lower temperature than the hotJupiters that have been studied so far. We find that the planet’s measured transmission spectrum lacks the expected water absorption feature for a hydrogen-dominated atmosphere, and is instead bestdescribed by a mode...

Abstract The atmospheric structure of WASP-12b has been hotly contested for years, with disagreements on the presence a thermal inversion as well carbon-to-oxygen ratio, C/O, due to retrieved abundances H 2 O, CO , and other included species such HCN C . Previously, these difficult-to-diagnose discrepancies have attributed model differences; assumptions in models were thought drive retrievals t...

Transit and radial velocity models were applied to archival data in order examine exoplanet properties, particular for the recently discovered super-Earth GJ 357b. There is however considerable variation estimated model parameters across literature, especially their uncertainty estimates. This applies even relatively uncomplicated systems basic parameters. Some published accuracy values thus ap...

An American Type Culture Collection reference strain and eight clinical strains of Mycobacterium tuberculosis, all of which were susceptible to isoniazid (INH) (mean MIC, 0.06 mg/liter) and negative for the Ser315Thr katG mutation, were left in their BACTEC 12B vials (for use with the BACTEC 460-TB method) containing 0.1 mg of INH per liter for periods of up to 28 days after the completion of t...
