Sums over paths adapted to quantum theory in phase space
(1986)
The concept of phase space plays a decisive role in the study of the transition from classical to quantum physics. This is particularly the case in areas such as nonlinear dynamics and chaos, geometric quantization and the ...
Contrasting Patterns of Population History and Seed-mediated Gene Flow in Two Endemic Costa Rican Oak Species
(2018)
Lower Central America is an important area to study recent population history and diversification of Neotropical species due to its complex and dynamic geology and climate. Phylogeographic studies in this region are few ...

The roles of growth regulation and appendage patterning genes in the morphogenesis of treehopper pronota.
(2022-06)
Treehoppers of the insect family Membracidae have evolved enlarged and elaborate pronotal structures, which is hypothesized to involve co-opted expression of genes that are shared with the wings. Here, we investigate the ...
Distribución espacio-temporal de la radiación solar neta en superficie sobre el trópico americano del Hemisferio Norte
(1996)
The results of Pinker and Laszlo's physical model for solar radiation budget are used in order to analize the daily net surface solar radiation (Q*) on tropical regions of the Northern lkmisphere of the Americas. The values ...
Low Froude Number stratified flows interacting with an isolated obstacle
(1997)
In previous studies it has been postulated that vortices, which are observed in the lee of mesoscale mountains,
may be due to a variety of interactions of the upstream flow with the mountain including the inviscid ...
