Given a graph G and a (multi-)set of pairs of vertices in it, the classical NP-hard maximum edge-disjoint-paths problem (MDP) is to connect as many of the given pairs as possible using pairwise edge-disjoint paths in G. We study a relative of this problem: we have a network with fixed link capacities that may have to service large demands when necessary. In particular, individual demands are allowed...
We consider the bilateral contract satisfaction problem arising from electrical power networks due to the proposed deregulation of the electric utility industry in the USA. Given a network and a (multi)set of pairs of vertices (contracts) with associated demands, the goal is to find the maximum number of simultaneously satisfiable contracts. We study how four different algorithms perform in fairly...
Orange fruit quality is highly dependent on time-specific expression of developmental genes in peel tissues, especially those controlling physical structure and synthesis of pigments and aromatic secondary metabolites. Using a custom microarray platform, we examined expression of 366 genes of interest in peel pericarp and endocarp during three developmental stages of Washington Navel orange fruit...
We report on evidence of long term stability inthe geographic pattern of geneticdifferentiation among cod (Gadus morhua)collected from 5 spawning banks offNewfoundland and Labrador over a periodspanning three decades (1964–1994) and 2orders of magnitude of population sizevariation. Six microsatellite DNA lociamplified from archived otoliths (1964 and1978) and contemporary (1990s) tissue samplesrevealed...
