The absence of women's scientific contributions in core UK pre‐university science qualifications

British Educational Research Journal, EarlyView.
Abstract Despite their groundbreaking contributions to our understanding of the natural world and the universe, women's roles in biology, chemistry, physics, astronomy, environmental science and geology remain largely absent from standard educational specifications in the United Kingdom (UK), particularly at Key Stage 4 (KS4) and Key Stage 5 (KS5), or ...

Gravitational particle production of scalars: analytic and numerical approaches including early reheating

Journal of High Energy Physics
Cosmological gravitational particle production (GPP) is a generic mechanism by which particles are produced during the inflationary epoch. In this work we consider the GPP of massive scalars in an effort to fully understand the spectrum of the produced ...

Neutrinos in cosmology

New Journal of Physics, 2004
The current status of neutrino cosmology is reviewed, from the question of neutrino decoupling and the presence of sterile neutrinos to the effects of neutrinos on the cosmic microwave background and large scale structure. Particular emphasis is put on cosmological neutrino mass measurements.

COSMOLOGICAL PERTURBATIONS IN RENORMALIZATION GROUP DERIVED COSMOLOGIES [PDF]

International Journal of Modern Physics D, 2004
A linear cosmological perturbation theory of an almost homogeneous and isotropic perfect fluid Universe with dynamically evolving Newton constant G and cosmological constant Λ is presented. A gauge invariant formalism is developed by means of the covariant approach, and the acoustic propagation equations governing the evolution of the comoving ...

The matrilineal Turn: Wiradjuri matrilineal leadership, colonial disruption, and the work of cultural return

Feminist Anthropology, EarlyView.
Abstract This article advances three claims regarding the matrilineal organization of Wiradjuri society in central New South Wales. Drawing on the late nineteenth and early twentieth century ethnographic record, it demonstrates that Wiradjuri descent, totem, moiety identity, and ceremonial authority were and are matrilineally organized, despite ...

Vacuum energy with mass generation and Higgs bosons

Physics Letters B, 2020
We discuss the Higgs mass and cosmological constant hierarchy puzzles with emphasis on the interplay of Poincaré invariance, mass generation and renormalization group invariance.

Bridging Worlds: Can Evidence, Regulation and Indigenous Leadership Shape the Future of Traditional, Complementary and Integrative Medicine?

The International Journal of Health Planning and Management, EarlyView.
ABSTRACT Background and need As the WHO Global Traditional Medicine Strategy 2025–2034 encourages countries to consider integrating traditional, complementary and integrative medicine (TCIM) into health systems, there is a need to clarify the principal scientific, regulatory, ethical, and governance challenges involved. Renewed global attention to TCIM,

Crescendo beyond the horizon: more gravitational waves from domain walls bounded by inflated cosmic strings

Journal of High Energy Physics
Gravitational-wave (GW) signals offer a unique window into the dynamics of the early universe. GWs may be generated by the topological defects produced in the early universe, which contain information on the symmetry of UV physics.

KiDS-1000 cosmic shear reanalysis using METACALIBRATION

Astronomy & Astrophysics
A number of cosmic shear studies have reported results that are in mild tension with Planck cosmic microwave background measurements. To explore if this can be caused by biases in shear estimation, we revisit data analyses from the Kilo-Degree Survey ...

Leading loop effects in pseudoscalar-Higgs portal dark matter

Journal of High Energy Physics, 2019
We examine a model with a fermionic dark matter candidate having pseudoscalar interaction with the standard model particles where its direct detection elastic scattering cross section at tree level is highly suppressed. We then calculate analytically the
