Split Attractor Flows and the Spectrum of BPS D-branes on the Quintic
(Institute of Physics, 2001)
We investigate the spectrum of type IIA BPS D-branes on the quintic from a four dimensional supergravity perspective and the associated split attractor flow picture. We obtain some very concrete properties of the (quantum ...
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 ...
