The Insistence of Blackness and the Persistence of Antiblackness in Ireland

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT This paper positions Ireland as a critical site for examining the insistence of blackness and an antiblackness created and sustained through Irish ethnonationalist imaginaries and exclusionary processes. Drawing on connected sociologies and Irish Black Studies, this enquiry argues that antiblackness in Ireland operates as a generational force,

Late-T And Y Dwarf Parallaxes From The Spitzer Space Telescope

open access: yes, 2017
Y dwarfs provide a unique opportunity to study free-floating, planetary-mass objects with atmospheric temperatures approaching those of known Jupiter-like exoplanets. Obtaining distances to these objects is an essential step in determining absolute physical parameters such as mass, age, and metallicity.

Prevalence and Factors Associated With Alleged Offending Among Children Aged 10–13 Years in the Northern Territory of Australia

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Recent policy discourse in Australia focuses on the minimum age of criminal responsibility with minimal attention to prevention strategies. Guided by theory which views child development within nested environmental contexts and recognises the cumulative impact of risk factors, this retrospective cohort study uses de‐identified linked ...

Magellan Adaptive Optics first-light observations of the exoplanet $\beta$ Pic b. I. Direct imaging in the far-red optical with MagAO+VisAO and in the near-IR with NICI

open access: yes, 2014
We present the first ground-based CCD ($\lambda < 1\mu$m) image of an extrasolar planet. Using MagAO's VisAO camera we detected the extrasolar giant planet (EGP) $\beta$ Pictoris b in $Y$-short ($Y_S$, 0.985 $\mu$m), at a separation of $0.470 \pm 0.010''$

Animal models of lung cancer: Phenotypic comparison of different animal models of lung cancer and their application in the study of mechanisms

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Grafts used to construct lung cancer animal models come from various sources, primarily cell lines, patient‐derived tumor tissues, and circulating tumor cells. Based on the sources of grafts and research objectives, lung cancer animal models can be categorized into several types: chemical‐induced models, orthotopic transplantation models, heterotopic ...

Spectroscopic and Photometric Analysis of the HW Vir Star PTF1 J011339.09+225739.1

open access: yesOpen Astronomy, 2018
HW Vir systems are rare eclipsing binary systems including a subdwarf B star (sdB) with a faint companion, mostly M-dwarfs. Up to now, 19 HW Vir systems have been published, three of them with substellar companions. We report the spectroscopic as well as

Midlife Steroid‐Binding Globulin Levels and In Vivo Neuroimaging Measures of Tau in Older Men and Women

open access: yesAnnals of Neurology, EarlyView.
Objective In men and women, sex steroid hormones have been associated with increased risk of Alzheimer's disease (AD) dementia. We aimed to investigate the influence of midlife testosterone and sex hormone binding globulin (SHBG) levels on later‐life in vivo markers of β‐amyloid (Aβ) and tau deposition in clinically healthy older men. Methods This time‐
