Corvus A: A Low-mass, Isolated Galaxy at 3.5 Mpc
We report the discovery of Corvus A, a low-mass, gas-rich galaxy at a distance of approximately 3.5 Mpc, identified in DR10 of the Dark Energy Camera Legacy Imaging Survey during the initial phase of our ongoing SEmi-Automated Machine LEarning Search for

‘A Sort of Armed Argument’: Ireland's Civil War of Words
Abstract This article sets out to contribute to the study of the languages of European civil wars through outlining and analysing the deployment of language as a weapon by the opposing sides of the Irish independence movement that split over the terms of the Anglo‐Irish Treaty of December 1921.

A Young Star Cluster in the Leo a Galaxy
We report a serendipitous discovery of a star cluster in the dwarf irregular galaxy Leo A. Young age (~28 Myr) and low mass (~510 M⊙) estimates are based on the isochrone fit assuming a metallicity derived for HII regions (Z = 0.0007).

Skepticism and Ontological Parsimony
ABSTRACT External world skepticism is often thought to entail that we should suspend judgment about the existence of the external world. I challenge this orthodoxy by arguing that, when combined with a plausible principle of ontological parsimony, the skeptical challenge intensifies into an argument for outright disbelief in the external world.

Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

Ultradeep Imaging of Nearby Dwarf Irregular Galaxies: Stellar Haloes and Disk Structure
We have examined the stellar structure of 10 nearby, low stellar mass (10 ^6 –6 × 10 ^7 M _⊙ ) dwarf irregular galaxies by fitting ellipses as a function of surface brightness on ultradeep V images. These are compared to far-ultraviolet images as tracers

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
