Micro‐habitat selection by boreal woodland caribou improves access to food

open access: yesWildlife Biology, EarlyView.
Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

Radio to infrared spectra of late-type galaxies with Planck and WMAP data

open access: yes, 2011
We use the Planck Early Release Compact Source Catalogue combined with WMAP and other archival measurements to construct continuum spectra of three nearby dusty star-forming galaxies: Messier 82, NGC 253 and NGC 4945.

An asteroseismic test of diffusion theory in white dwarfs [PDF]

open access: yes, 2005
The helium-atmosphere (DB) white dwarfs are commonly thought to be the descendants of the hotter PG1159 stars, which initially have uniform He/C/O atmospheres.

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

open access: yesWildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

An observational test of common-envelope evolution

open access: yes, 1995
By analysing and modelling the change in the abundance ratio of $^{12}$C/$^{13}$C and $^{16}$O/$^{17}$O on the surface of the lower mass star of a binary during the common-envelope (CE) phase of evolution, we propose a simple observational test of the CE

The MUSE view of He 2-10: no AGN ionization but a sparkling starburst [PDF]

open access: yes, 2017
We study the physical and dynamical properties of the ionized gas in the prototypical HII galaxy Henize 2-10 using MUSE integral field spectroscopy. The large scale dynamics is dominated by extended outflowing bubbles, probably the results of massive gas

Crossroads of the Life of Vittorio Alfieri

open access: yesJournal for Eighteenth-Century Studies, EarlyView.
Abstract This article examines Vittorio Alfieri's Life as a deliberately constructed narrative of cultural, linguistic, and political self‐fashioning within eighteenth‐century European intellectual networks. Rather than treating the autobiography as a transparent record of experience, the article argues that Alfieri retrospectively reorganizes his ...

Vibration Analysis on the Bridge Structures Caused by Train Load

open access: yesJurnal Teknik Sipil dan Perencanaan, 2020
: The Muktiharjo Kaligawe railway bridge or BH 9 which located in KM 3+450 is truss bridge that has a special function,that is as a railway network where the BH 9 is a bridge with the steel frame type.

Evidence of nuclear disks in starburst galaxies from their radial distribution of supernovae

open access: yes, 2012
Galaxy-galaxy interactions are expected to be responsible for triggering massive star formation and possibly accretion onto a supermassive black hole, by providing large amounts of dense molecular gas down to the central kiloparsec region.
