Arthritis Care &Research, EarlyView.Objective Race and household income impact outcomes in patients with rheumatic conditions; however, their role in pediatric antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV) remains poorly understood. We aimed to evaluate whether race and ethnicity and household income are associated with severe AAV disease and renal outcomes among

On negative infrared flares of flare stars
The Astrophysical Journal, 1988 The basic formulation of the so-called fast electron hypothesis is presented. According to this hypothesis, the optical flares of UV Cet-type stars are caused by the inverse compton effect, i.e., nonthermal interactions of infrared photons with fast electrons (E equal to about 1.5 MeV), as well as nonthermal bremsstrahlung.

New EUV Selected Flare Stars [PDF]
International Astronomical Union Colloquium, 1995 The ROSAT Wide Field Camera all-sky EUV survey of 1990-91 identified over 200 active late-type stars (Pounds et al. 1993). Most of these were not known to be active prior to the survey and follow-up optical spectroscopy has been successful in selecting the most active dMe stars.

Flare stars at radio wavelengths [PDF]
, 1989 The radio emission from dMe flare stars is discussed using Very Large Array and Arecibo observations as examples. Active flare stars emit weak, unpolarized, quiescent radio radiation that may be always present.

Arthritis Care &Research, EarlyView.Objective Although the definition of a gout flare is well established, the state of gout flare resolution has not yet been defined. This study aimed to explore patients’ experiences and perceptions of gout flare resolution. Methods Semistructured interviews were conducted with 24 people with gout, guided by open‐ended questions exploring their ...

Detection of Radio Emission from Superflaring Solar-type Stars in the VLA Sky Survey
The Astrophysical JournalSolar-type stars have been observed to flare at optical wavelengths with energies much higher than is observed for the Sun. To date, no counterparts have been observed at longer wavelengths.
