A Census of Pulsars in Possible Association with Galactic Open Clusters

The Astrophysical Journal Letters
Among the ∼4000 known pulsars in our Galaxy, ≲10% are found in globular clusters, but none has been confirmed in any open clusters yet, although they outnumber globular clusters by about 20 times.

Real‐world insights on switching aflibercept dosage for enhanced outcomes in age‐related macular degeneration (RISE‐AMD): Safety data

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate real‐world safety experience with aflibercept 8 mg in a large case series of patients with neovascular age‐related macular degeneration (nAMD). Methods Due to a high proportion of patients on short treatment intervals, patients with nAMD at a Danish tertiary retina clinic were systematically switched to aflibercept 8 mg ...

A search for radio pulsars: from millisecond pulsars to magnetars

, 2012
Pulsars are rapidly rotating neutron stars that emit radiation in beams observable with telescopes at various wavelengths. They are used to study a wide variety of physical and astrophysical phenomena, e.g. for the detection of gravitational waves.

Polarimetric Evidence of the First White Dwarf Pulsar: The Binary System AR Scorpii

Galaxies, 2018
The binary star AR Scorpii was recently discovered to exhibit high amplitude coherent variability across the electromagnetic spectrum (ultraviolet to radio) at two closely spaced ∼2 min periods, attributed to the spin period of a white dwarf and the beat

TMEM16A channel signalling microdomains in the regulation of vascular function

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,
