Interdiction Models and Heuristics for Graph Propagation

Networks, EarlyView.
ABSTRACT Given a graph G=(V,E)$$ G=\left(V,E\right) $$ and a set S⊂V$$ S\subset V $$ of activated/infected nodes, we consider the problem of determining the set of c$$ c $$ nodes that minimizes the network propagation on the subgraph that results from the removal of those c$$ c $$ nodes. To measure network propagation, we assume that a node i$$ i $$ is

Novelty for the flora of Espírito Santo, Brazil: a new species of Ouratea Aubl. (Ochnaceae)

Nordic Journal of Botany, EarlyView.
Here, we describe and illustrate the new species Ouratea oberdanii Fraga & Deccache, which is named after Dr Oberdan José Pereira. This new species is found in the mountainous regions of the evergreen Atlantic Forest in the Brazilian state of Espírito Santo. Ouratea oberdanii is similar to O. linearis (A.Gray) Sastre & Offroy and O.

Canscora agni (Gentianaceae), a new species from the fire‐prone Indian savannas

Nordic Journal of Botany, EarlyView.
We describe Canscora agni from the Indian savannas as a distinct species which differs from its allied species Canscora alata in having fewer and shorter leaves, pedicel‐wings unequal across the length, bracts with glandular hair on the margins, calyx‐wings being four, wider, up to 2.3 mm, with distinct reticulate venation and having ovary length up to
