But exactly how large-scale spatial coherence over the entire surface of the Sun can arise at high magnetic Reynolds numbers, as lines of magnetic field are dragged along by fluid flow, has...

SCIENTIFIC REPORT Vitrectomy and gas for inferior break retinal detachments: are the results comparable to vitrectomy, gas, and scleral buckle?

Aims: To compare the success rates of vitrectomy and gas with vitrectomy, gas, and buckle in the treatment of inferior break retinal detachments. Methods: A retrospective case note review of 86 patients who presented with inferior break retinal detachments was carried out.
