A Young Star Cluster in the Leo a Galaxy
Open Astronomy, 2015 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).

Spectral Energy Distributions for 258 Local Volume Galaxies
The Astronomical Journal, 2023 We present model spectral energy distribution (SED) fits to ultraviolet/optical/infrared observations for the 258 nearby galaxies in the Local Volume Legacy survey, a sample dominated by lower-luminosity dwarf irregular systems.

Journal of Sleep Research, EarlyView.ABSTRACT Home sleep apnea tests (HSATs) have emerged as alternatives to in‐laboratory polysomnography (PSG), but Type IV HSATs often show limited diagnostic performance. This study clinically validates SleepAI, a novel remote digital health system that applies AI algorithms to raw oximetry data for automated sleep staging and obstructive sleep apnea ...

Periodic bursts of star formation in irregular galaxies [PDF]
Astronomy & Astrophysics, 2004 We present N-body/SPH simulations of the evolution of an isolated dwarf galaxy including a detailed model for the ISM, star formation and stellar feedback. Depending on the strength of the feedback, the modelled dwarf galaxy shows periodic or quasi-periodic bursts of star formation of moderate strength.

Anxious Projections: Mass Hysteria and the Problem of Interpretation
Medical Anthropology Quarterly, EarlyView.Abstract Stories of “mass hysteria” among teenage girls have often graced the headlines of Nepal's local and national newspapers, creating a public spectacle of a strange and mysterious form of affliction. Treatments include both shamanic rituals and psychosocial interventions, a new therapeutic modality that has gained prominence over the past two ...

Morphology of star formation regions in irregular galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 The location of HII regions, which indicates the locus of present star formation in galaxies, is analyzed for a large collection of 110 irregular galaxies (Irr) imaged in H$ $ and nearby continuum. The analysis is primarily by visual inspection, although a two-dimensional quantitative measure is also employed.

Hunting for Paradoxes: A Research Strategy for Cognitive Science
Topics in Cognitive Science, EarlyView.Abstract How should we identify interesting topics in cognitive science? This paper suggests that one useful research strategy is to hunt for, and attempt to resolve, paradoxes: that is, apparent or real contradictions in our understanding of the mind and of thought.

Experimental Physiology, EarlyView.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 ...
