The faint outer regions of the Pegasus dwarf irregular galaxy: A much larger and undisturbed galaxy [PDF]

, 2009
We investigate the spatial extent and structure of the Pegasus dwarf irregular galaxy (PegDIG) using deep, wide-field, multicolour CCD photometry from the Sloan Digital Sky Survey (SDSS) and new deep H I observations.

From cells to pixels: A decision tree for designing bioimage analysis pipelines

Journal of Microscopy, EarlyView.
Abstract Bioimaging has transformed our understanding of biological processes, yet extracting meaningful information from complex datasets remains a challenge, particularly for biologists without computational expertise. This paper proposes a simple general approach, to help identify which image analysis methods could be relevant for a given image ...

Clinical Validation of Artificial Intelligence Algorithms for the Diagnosis of Adult Obstructive Sleep Apnea and Sleep Staging From Oximetry and Photoplethysmography—SleepAI

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 ...

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.

BVR photometry of the resolved dwarf galaxy Ho IX

, 2004
We present BVR CCD photometry down to limiting magnitude B=23.5 mag for 232 starlike objects and 11 diffuse objects in a 5.4' x 5.4' field of Ho IX. The galaxy is a gas-rich irregular dwarf galaxy possibly very close to M 81, which makes it especially ...

Stellar Content and Recent Star Formation History of the Local Group Dwarf Irregular Galaxy IC 1613 [PDF]

, 2007
We present resolved-star VI photometry of the Local Group dwarf irregular galaxy IC 1613 reaching I ∼ 23.5, obtained with the wide-field camera at the 2.5 m Isaac Newton Telescope. A fit to the stellar density distribution shows an exponential profile of
