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).

The Isaac Newton Telescope Monitoring project: Stellar population in the IC 10 dwarf irregular galaxy [PDF]
Iranian Journal of Astronomy and Astrophysics, 2019 We have conducted an optical monitoring survey of IC 10 dwarf irregular galaxy in the Local Group, using the Isaac Newton Telescope (INT) with the wide-field camera (WFC), to identify the Asymptotic Giant Branch stars (AGBs).

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 ...

Prioritized Real‐Time UAV‐Based Vessel Detection for Efficient Maritime Search
Journal of Field Robotics, EarlyView.ABSTRACT Real‐time vessel detection in maritime environments is crucial for diverse applications requiring speed and accuracy. Static camera views often introduce blind spots, compromising detection efficiency. This paper proposes a novel, real‐time UAV‐based system that uses a dynamic camera control strategy to address this limitation.

The FEBS Journal, EarlyView.Antifreeze proteins from winter‐active spiders were purified using their affinity for ice. After LC–MSMS characterization, corresponding transcripts were identified. The antifreeze protein folds as a β‐solenoid with a large flat ice‐binding site on one surface and can bind to ice crystals and prevent their growth at −4 °C.
