Hierarchical path-finding for Navigation Meshes (HNA*) [PDF]

open access: yes, 2016
Path-finding can become an important bottleneck as both the size of the virtual environments and the number of agents navigating them increase. It is important to develop techniques that can be efficiently applied to any environment independently of its ...

Harry Hess and sea-floor spreading [PDF]

open access: yes, 1999
Harry Hess's hypothesis of sea-floor spreading brought together his long-standing interests in island arcs, oceanic topography, and the oceanic crust. The one unique feature of Hess's hypothesis was the origin of the oceanic crust as a hydration rind on ...

Fungal diversity is not determined by mineral and chemical differences in serpentine substrates.

open access: yesPLoS ONE, 2012
The physico-chemical properties of serpentine soils lead to strong selection of plant species. Whereas many studies have described the serpentine flora, little information is available on the fungal communities dwelling in these sites. Asbestos minerals,

Are Ophiolitic Substrates Drivers for Reticulate Evolution in Armeria (Plumbaginaceae)?

open access: yesEcology and Evolution
Ultramafic substrates can play a role in fostering ecological adaptation and microevolutionary dynamics. The Armeria denticulata complex includes two flowering plant species (A. denticulata and A.

Global Distribution of Serpentine on Mars

open access: yesGeophysical Research Letters
The distribution and origin of serpentine on Mars can provide insights into the planet's aqueous history, habitability, and past climate. In this study, we used dynamic aperture factor analysis/target transformation applied to 15,760 images from the ...
