How Political Science Can Contribute to Public Health: A Response to Gagnon and Colleagues

Dark Radiation and Localization of Gravity on the Brane

We discuss the dynamics of a spherically symmetric dark radiation vaccum in the Randall-Sundrum brane world scenario. Under certain natural assumptions we show that the Einstein equations on the brane form a closed system. For a de Sitter brane we determine exact dynamical and inhomogeneous solutions which depend on the brane cosmological constant, on the dark radiation tidal charge and on its ...

Why and How Political Science Can Contribute to Public Health? Proposals for Collaborative Research Avenues

Written by a group of political science researchers, this commentary focuses on the contributions of political science to public health and proposes research avenues to increase those contributions. Despite progress, the links between researchers from these two fields develop only slowly. Divergences between the approach of political science to public policy and the expectations that public hea...

From Massive Gravity to Dark Matter Density

Massive gravity previously constructed as the spin-2 quantum gauge theory is studied in the classical limit. The vector graviton field v which does not decouple in the limit of vanishing graviton mass gives rise to a modification of general relativity. The modified Schwarzschild solution contains a contribution from the v-field which can be interpreted as the dark matter mass density. We calcul...
