Observational Manifestations of the First Protogalaxies in the 21 cm Line
, 2012 The absorption properties of the first low-mass protogalaxies (mini-halos) forming at high redshifts in the 21-cm line of atomic hydrogen are considered. The absorption properties of these protogalaxies are shown to depend strongly on both their mass and

Advanced Intelligent Systems, EarlyView.During lengthy minimally invasive surgeries, fatigue can cause surgeon tremor and poor endoscopic coordination. This study proposes a robot‐assisted endoscopic adjustment system. It employs a lightweight instrument detection model and a hierarchical multiconstraint controller for visual servoing.

The Insistence of Blackness and the Persistence of Antiblackness in Ireland
Australian 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,

Australian Journal of Social Issues, EarlyView.ABSTRACT Migrant healthcare workers in Australia find themselves at the centre of three intersecting concerns, often presented as ‘crises’ in contemporary discourse: the ‘care crisis’, the ‘housing crisis’ and the ‘migration crisis.’ Yet their own perspectives on these issues are rarely foregrounded. This paper explores the role of homeownership in the
