Stroke is one of the leading causes disability and mortality. Both short long sleep durations are associated with adverse health outcomes. Cross-sectional studies have shown an increased prevalence stroke in sleepers. Long duration increases incidence mortality prospective epidemiological studies. Accumulating evidence suggests that magnitude association between appears to be stronger for longe...

Millisecond magnetars produced in the center of dying massive stars are one prominent model to power gamma-ray bursts (GRBs). However, their detailed nature remains a mystery. To explore effects initial mass, rotation rate, wind mass loss, and metallicity on GRB progenitors newborn magnetar properties, we evolve 227 $10-30~M_\odot$ single star models from pre-main-sequence core collapse by usin...
