A more realistic representation of overshoot at the base of the solar convective envelope as seen by helioseismology [PDF]
, 2011 The stratification near the base of the Sun's convective envelope is governed by processes of convective overshooting and element diffusion, and the region is widely believed to play a key role in the solar dynamo. The stratification in that region gives

Sheaf-Theoretic Stratification Learning from Geometric and Topological Perspectives [PDF]
, 2020 In this paper, we investigate a sheaf-theoretic interpretation of stratification learning from geometric and topological perspectives. Our main result is the construction of stratification learning algorithms framed in terms of a sheaf on a partially ...

Mesoscale variability of the Mexican Tropical Pacific using TOPEX and SeaWiFS data
Ciencias Marinas, 2006 The Mexican Tropical Pacific has oligotrophic characteristics; however, it sustains an abundant biodiversity, mainly because of upwelling promoted by its relatively shallow thermocline, strong winds and mesoscale eddies.
