New Mechanism of Pulsar Radio Emission

open access: yesPhysical Review Letters, 2002
It is shown that pulsar radio emission can be generated effectively through a streaming motion in the polar-cap regions of a pulsar magnetosphere causing nonresonant growth of waves that can escape directly. As in other beam models, a relatively low-energy high-density beam is required. The instability generates quasi-transverse waves in a beam mode at

Imaging findings differentiating uterine cavity polypoidal masses

open access: yesJournal of Endometriosis and Uterine Disorders
Uterine leiomyomas uncommonly manifest as submucous pedunculated masses, a few of which are adenomyomas. These must be differentiated from endometrial polyps (EPs) due to their different malignant potential, prognosis and management.
