A 25-year-old woman presented with fever of unknown origin, exhibiting malaise and low-grade fevers in evenings. These fevers exhibited a pattern of starting mid-menstrual cycle with resolution around the onset of menses, matching a pattern of "habitual hyperthermia" reported by H. Reimann in the 1930s. Extensive workup was unremarkable, and the fevers improved on oral synthetic estrogen and pr...

METHODS Within the Southampton Women's Survey the PA levels of 593 4-year-old children (51% female) were measured using (Actiheart) accelerometr...

Abstract The technique of transmission spectroscopy—the variation a planetary radius with wavelength due to opacity sources in the planet’s terminator region—has been one most successful characterization exoplanet atmospheres date, providing key insights into composition and structure these distant worlds. A common assumption made when using this technique, however, is that variations are same ...
