‘Turkeys Cannot Vote for Christmas’: Why Epistemic Disobedience in an Anti‐Black World Matters
Australian Journal of Social Issues, EarlyView.ABSTRACT Never in the history of global coloniality has the idea of epistemic disobedience been as important as in the 21st century. This is not only because the struggle for decolonisation has shifted from physical confrontation between the coloniser and the colonised into a battle of ideas but also because the former has deployed the idea of ...

Unified Dark Matter scalar field models with fast transition [PDF]
, 2011 We investigate the general properties of Unified Dark Matter (UDM) scalar field models with Lagrangians with a non-canonical kinetic term, looking specifically for models that can produce a fast transition between an early Einstein-de Sitter CDM-like era

Inferring Cosmological Parameters with Evidential Physics-Informed Neural Networks
UniverseWe examine the use of a novel variant of Physics-Informed Neural Networks to predict cosmological parameters from recent supernovae and baryon acoustic oscillations (BAO) datasets. Our machine learning framework generates uncertainty estimates for target

Non-singular pre-big bang scenarios from all-order α′ corrections
Journal of High Energy Physics, 2023 We reformulate in Hamiltonian language the recent proposal by Hohm and Zwiebach of an action yielding the most general O(d, d)-symmetric string cosmology equations, at tree-level in the string-loop expansion, but to all orders in the α′ expansion.

The Anatomical Record, EarlyView.Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

A Critique of Cosmological Natural Selection [PDF]
, 2004 Mathematical physicist Lee Smolin has proposed a theory of Cosmological natural selection which, he argues, explains the existence of our life-supporting universe, and which, he claims, is superior to Anthropic Principle explanations.

The Open Journal of Astrophysics, 2016 It has recently been shown, in flat Robertson-Walker geometries, that the dynamics of gravitational actions which are minimally coupled to matter fields leads to the appearance of “attractors” - sets of physical observables on which phase space measures ...

Journal of High Energy Physics, 2023 Nonlinear sigma models on de Sitter background have proved a useful prototype for quantum gravity in summing the large logarithms which arise from loop corrections.
