Eleven spherically symmetric constant density solutions with cosmological constant

, 2006
Einstein's field equations with cosmological constant are analysed for a static, spherically symmetric perfect fluid having constant density. Five new global solutions are described.

‘Vitamins’, shortcuts, and athletic citizenship in Ethiopia and Cameroon: considering sporting ethics beyond biomedicine « Vitamines », courts‐circuits et citoyenneté sportive en Éthiopie et au Cameroun : l’éthique du sport, au‐delà de la biomédecine

Journal of the Royal Anthropological Institute, EarlyView.
This article argues that the current way of thinking about ethics in sport in primarily biomedical terms, and in particular in terms of the presence of particular pharmaceutical substances, fails to account for broader notions of sporting ethics and fairness in the Global South.

Hadrons, superconductor vortices, and cosmological constant

Physics Letters B
We explore the roles of the trace anomaly in several hadron properties. We derive the scale invariant expression for the pressure from the gravitational form factors (GFF) of QCD which results in consistent results for the mass and rest energy from the ...

Holographic (De)confinement Transitions in Cosmological Backgrounds

, 2011
For type IIB supergravity with a running axio-dilaton, we construct bulk solutions which admit a cosmological background metric of Friedmann-Robertson-Walker type.

Tactile tensions: uncertainty, mutuality, and therianthropic nightmares in Highland Odisha Tact et tensions : incertitude, mutualité et cauchemars thérianthropiques dans les hautes terres de l'Odisha

Journal of the Royal Anthropological Institute, EarlyView.
In the central highlands of Odisha, India, Kutia Kondh families navigate a precarious reality shaped by productive autonomy, decentralized authority, and material and relational uncertainty. Abundance and destitution are finely balanced in a world where humans, animals, ancestors, and spirits are co‐present and co‐dependent but also opaque and ...

Upper Bounds on the Mass of Fundamental Fields from the Primordial Universe

The Astrophysical Journal
We study the fluctuations in the vacuum zero-point energy associated with quantum fields and their statistical distributions during inflation. It is shown that the perturbations in the vacuum zero-point energy have large amplitudes that are highly non ...

Quantum Fields and the Cosmological Constant

Universe
It has been shown that if one solves self-consistently the semiclassical Einstein equations in the presence of a quantum scalar field, with a cutoff on the number of modes, spacetime become flatter when the cutoff increases. Here, we extend the result to

Axiomatic approach to the cosmological constant

, 2008
A theory of the cosmological constant Lambda is currently out of reach. Still, one can start from a set of axioms that describe the most desirable properties a cosmological constant should have.

Weaponizing Nature, Naturalizing Violence: Anthropologies of Ecofascism

American Anthropologist, EarlyView.
ABSTRACT After decades of denial and obstruction, the global Right is increasingly willing to acknowledge that climate change is a threat to lives and lifeways everywhere. Moreover, some seize on the specter of ecological collapse to advance fascistic politics.
