Connectivity requirements are a common component of forest planning models, with important examples arising in wildlife habitat protection. In harvest scheduling models, one way of addressing preservation concerns consists of requiring that large contiguous patches of mature forest are maintained. In the context of nature reserve design, it is common(More)
Let G = (V, E) be a graph. A nonempty subset S ⊆ V is a (strong defensive) alliance of G if every node in S has at least as many neighbors in S than in V \ S. This work is motivated by the following observation: when G is a locally structured graph its nodes typically belong to small alliances. Despite the fact that finding the smallest alliance in a graph(More)
suMMARY Ankle valgus is an insidious deformity that may develop during childhood due to a variety of etiologies including cerebral palsy. This may be concomitant, with or mistaken for hind foot valgus. These conditions pathology alter the growth rate of the distal fibula resulting in shortening and ankle valgus. These patients have problems with the ankle(More)

A major challenge in forest harvest scheduling is to balance economic gain with the preservation of wildlife habitat. One way of addressing preservation concerns in profit maximizing models consists in requiring that large contiguous patches of mature forest to be left standing after harvest. Another way of addressing such concerns in the context of nature(More)
