Cosmic acceleration in the nonlocal approach to the cosmological constant problem
European Physical Journal C: Particles and Fields, 2018 We have recently constructed a manifestly local formulation of a nonlocal approach to the cosmological constant problem which can treat with quantum effects from both matter and gravitational fields. In this formulation, it has been explicitly shown that

Journal of the Royal Anthropological Institute, EarlyView.While death remains a popular topic for anthropology, relatively few ethnographic accounts consider the modern bureaucratic processes accompanying it. One such process is public health autopsy, which scholars have largely taken for granted. Existing analysis has regarded it as a form of ‘cultural brokering’ and autopsy reluctance in communities is seen,

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.

Journal of the Royal Anthropological Institute, EarlyView.In recent decades, solid waste has proliferated worldwide, becoming a pressing global issue. This article explores the role of Indigenous people dwelling within and upon emerging waste scenarios, with a specific focus on involved forms of sociality and ontological contestation. Drawing on the case of a municipal landfill sited on a Guarani community in

Physics and Cosmology : the Milli-Electron-Volt Scale
, 2009 A short review about vacuum energy and the cosmological constant is presented. The observed acceleration of the universe introduces a new meV energy scale. The problem is that, theoretically, the predicted vacuum energy is many orders of magnitude larger

American Ethnologist, EarlyView.Abstract This commentary examines how artificial intelligence (AI) reshapes scholarly authorship through Fredrik Barth's figures of the guru and the conjurer. The guru instructs within moral and scholarly frameworks, while the conjurer mystifies through spectacle.

A speculative approach to quantum gravity
Electronic Journal of Differential Equations, 2000 The bare bones of a theory of quantum gravity are exposed. It may have the potential to solve the cosmological constant problem. Less certain is its behavior in the Newtonian limit.

The cosmological nature of the dark Universe
European Physical Journal C: Particles and Fields, 2018 This paper deals with the cancellation mechanism, which identifies the energy density of space-time expansion in an empty universe with the zero-point energy density and avoids the scale discrepancy with the observed energy density (cosmological constant

Gravity in the dynamical approach to the cosmological constant
, 2003 One of the most disturbing difficulties in thinking about the cosmological constant is that it is not stable under radiative corrections. The feedback mechanism proposed in [hep-th/0306108] is a dynamical way to protect a zero or small cosmological ...
