Tropical Linear Spaces and Tropical Convexity [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2015
In classical geometry, a linear space is a space that is closed under linear combinations. In tropical geometry, it has long been a consensus that tropical varieties defined by valuated matroids are the tropical analogue of linear spaces. It is not difficult to see that each such space is tropically convex, i.e.

Tropical dermatology: viral tropical diseases

open access: yesJournal of the American Academy of Dermatology, 2003
Viruses are important pathogens in tropical areas; most of them, especially the tropical hemorrhagic fevers, produce mucocutaneous manifestations. More than any other kind of pathogen, viruses have the possibility for being widespread, since they have a greater probability of mutation than do bacteria, can cross species barriers easily, and infect both
