Spin foam models of Riemannian quantum gravity (2008)
John C. Baez, J. Daniel Christensen, Thomas R. Halford, C. Tsang
Abstract. Using numerical calculations, we compare three versions of the Barrett– Crane model of 4-dimensional Riemannian quantum gravity. In the version with face and edge amplitudes as described...
A dynamic upper atmosphere of Venus as revealed by VIRTIS on Venus Express (2007)
Drossart, P., Piccioni, G., Gerard, M., Sanchez-Lavega, A., Lopez-Valverde, M. A., Hueso, R., ...
The upper atmosphere of a planet is a transition region in which energy is transferred between the deeper atmosphere and outer space. Molecular emissions from the upper atmosphere (90–120 km...
