Constraints on stellar parameters of the SPB star HD182255 from complex asteroseismology

, 2012
Seismic modeling of the Slowly Pulsating B-type star HD182255 yields strong constraints on the radial orders of the two dominant modes. For these frequencies, we derive also the empirical values of the complex nonadiabatic parameter $f$.

Dark-ages Reionization and Galaxy Formation Simulation - X. The small contribution of quasars to reionization

, 2017
Motivated by recent measurements of the number density of faint AGN at high redshift, we investigate the contribution of quasars to reionization by tracking the growth of central supermassive black holes in an update of the Meraxes semi-analytic model ...

Galaxy And Mass Assembly (GAMA): end of survey report and data release 2 [PDF]

, 2015
The Galaxy And Mass Assembly (GAMA) survey is one of the largest contemporary spectroscopic surveys of low redshift galaxies. Covering an area of ˜286 deg2 (split among five survey regions) down to a limiting magnitude of r < 19.8 mag, we have collected ...

Prenatal Environmental Hypoxia Enhances Adult Hypoxia Tolerance in Brandt's Voles (Lasiopodomys brandtii): Behavioral and Transcriptomic Insights

Integrative Zoology, EarlyView.
Prenatal hypoxia enhances adult hypoxia tolerance in Brandt's voles, preserving cognitive and memory functions. Transcriptomic analysis reveals adaptive changes in energy metabolism, oxygen transport, and neuroprotective mechanisms, highlighting developmental plasticity.

Observing the very low-surface brightness dwarfs in a deep field in the VIRGO cluster: constraints on Dark Matter scenarios [PDF]

, 2017
We report the discovery of 11 very faint (r< 23), low surface brightness ({\mu}_r< 27 mag/arcsec^2) dwarf galaxies in one deep field in the Virgo cluster, obtained by the prime focus cameras (LBC) at the Large Binocular Telescope (LBT).

Malaysia's Ambivalent Middle Power Status: A Global South Perspective From a Reconceptualised Geoeconomics

Global Policy, EarlyView.
ABSTRACT This article adds a geoeconomics dimension to the geopolitics‐focused middle power literature that generally depicts Malaysia as an ambivalent middle power, especially from the identity and behavioral perspectives, even if the country's middle power status stands on stronger capability indicators.

Consistency of cosmic microwave background temperature measurements in three frequency bands in the 2500-square-degree SPT-SZ survey

, 2019
We present an internal consistency test of South Pole Telescope (SPT) measurements of the cosmic microwave background (CMB) temperature anisotropy using three-band data from the SPT-SZ survey.

Automorphisms of Real 4 Dimensional Lie Algebras and the Invariant Characterization of Homogeneous 4-Spaces [PDF]

, 2002
The automorphisms of all 4-dimensional, real Lie Algebras are presented in a comprehensive way. Their action on the space of $4\times 4$, real, symmetric and positive definite, matrices, defines equivalence classes which are used for the invariant ...
