Matter coupling in partially constrained vielbein formulation of massive gravity [PDF]

, 2015
We consider a consistent linear effective vielbein matter coupling without introducing the Boulware-Deser ghost in ghost-free massive gravity. This is achieved in the partially constrained vielbein formulation.

Post‐Traumatic Growth in the Global South: Possibilities in Relational Ethics from Communities to Classrooms

TESOL Quarterly, EarlyView.
Abstract This article reports on a qualitative study of the way instructors and students understand and respond to traumatizing events in a Sri Lankan university. It shows how the attitudes and practices in the society at large are carried over to classrooms even though local institutions do not have a programmatic trauma‐informed pedagogy.

On the effect of renormalization group improvement on the cosmological power spectrum

European Physical Journal C: Particles and Fields, 2018
Asymptotically safe quantum gravity predicts running gravitational and cosmological constants, while it remains a meaningful quantum field theory because of the existence of a finite number of non-Gaussian ultraviolet fixed points.

From the manager's point of view: work intensification, posthuman ethnography, and healthcare in England Du point de vue des managers : intensification du travail, ethnographie post‐humaine et soins de santé en Angleterre

Journal of the Royal Anthropological Institute, EarlyView.
Drawing on fieldwork conducted in a hospital in Greater Manchester, England in 2016–17, we describe how a set of national health priorities were translated into work for hospital managers and clinicians during a period of significant organizational pressure.

Backreaction in cosmic screening approach

Physics Letters B, 2023
We investigate the backreaction of nonlinear perturbations on the global evolution of the Universe within the cosmic screening approach. To this end, we have considered the second-order scalar perturbations.

Dependence of Inflationary Reconstruction upon Cosmological Parameters

, 1995
The inflationary potential and its derivatives determine the spectrum of scalar and tensor metric perturbations that arise from quantum fluctuations during inflation.

On Non-Gaussianity in the Curvaton Scenario [PDF]

, 2003
Since a positive future detection of non-linearity in the cosmic microwave background anisotropy pattern might allow to descriminate among different mechanisms giving rise to cosmological adiabatic perturbations, we study the evolution of the second ...

Phantasmic Encounters in the Arctic: Haunting Materialities Beyond the Ghosts of War

Anthropology of Consciousness, EarlyView.
ABSTRACT In the vast north, ghostly experiences are common for locals and outsiders alike. Here, we explore how cultural‐natural attributes, like remoteness and extreme seasonal variation, compound experiences of the haunting in visceral ways. This provides the Arctic region with an unusually pronounced baseline of other‐than‐human agency, which in the

Matter perturbations in scaling cosmology [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
A suitable nonlinear interaction between dark matter with an energy density $ _{M}$ and dark energy with an energy density $ _{X}$ is known to give rise to a non-canonical scaling $ _{M} \propto _{X}a^{- }$ where $ $ is a parameter which generally deviates from $ =3$.

Late‐Holocene evolution of a small Sub‐Arctic glacier, Gljúfurárjökull (Tröllaskagi, northern Iceland)

Boreas, EarlyView.
Gljúfurárjökull, located on the Tröllaskagi Peninsula in northern Iceland, is a small glacier approximately 3.8 km in length. This study analyses the glacier's evolution through a combination of methods including: (i) geomorphological mapping, (ii) Cosmic‐Ray Exposure (CRE) dating, (iii) lichenometry and (iv) palaeoglacier reconstruction (volume ...
