The faintest galaxies

, 2010
We investigate the nature of Ultra Faint dwarf spheroidal galaxies (UF dSphs) in a general cosmological context, simultaneously accounting for various "classical" dSphs and Milky Way (MW) properties, including their Metallicity Distribution Function (MDF)

The Inner Halo of M87: A First Direct View of the Red-Giant Population [PDF]

, 2010
An unusually deep (V,I) imaging dataset for the Virgo supergiant M87 with the Hubble Space Telescope ACS successfully resolves its brightest red-giant stars, reaching M_I(lim) = -2.5.

Breeding cold‐tolerant Orius laevigatus lines improves thermal tolerance and body size: implications for biological control

Pest Management Science, EarlyView.
Biological control agents performance is influenced by temperature. Two cold‐tolerant lines of O. loevigatus were developed, improving their fitness at both low and high temperatures, offering advantages far augmentative biological control. Abstract BACKGROUND The performance of biological control agents (BCAs) is strongly influenced by environmental ...

Multi-Element Abundance Measurements from Medium-Resolution Spectra. III. Metallicity Distributions of Milky Way Dwarf Satellite Galaxies [PDF]

, 2011
We present metallicity distribution functions (MDFs) for the central regions of eight dwarf satellite galaxies of the Milky Way: Fornax, Leo I and II, Sculptor, Sextans, Draco, Canes Venatici I, and Ursa Minor.

Efficient Masked Autoencoder for Birdsong Representation with Applications on Wild Bird Species Classification

Integrative Zoology, EarlyView.
Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...
