Dark-Matter-Induced Weak Equivalence Principle Violation
(American Physical Society, 2009)
A long-range fifth force coupled to dark matter can induce a coupling to ordinary matter if the dark matter interacts with Standard Model fields. We consider constraints on such a scenario from both astrophysical observations ...
Patterns of Water and Heat Flux Across a Biome Gradient From Tropical Forest to Savanna in Brazil
(American Geophysical Union, 2009)
We investigated the seasonal patterns of water vapor and sensible heat flux along a tropical biome gradient from forest to savanna. We analyzed data from a network of flux towers in Brazil that were operated within the ...
Explosively launched spores of ascomycete fungi have drag-minimizing shapes
(Proceedings of the National Academy of Sciences, 2008)
The forcibly launched spores of ascomycete fungi must eject through several millimeters of nearly still air surrounding fruiting bodies to reach dispersive air flows. Because of their microscopic size, spores experience ...
