Outwelling from arid mangrove systems is sustained by inwelling of seagrass productivity
(
Inter-Research
, 2014 , Article)
Mangrove forest productivity is normally sustained by nutrients from terrestrial runoff, with freshwater inputs driving the resulting outwelling of production, but arid mangroves lack this input. The movement of material ...
Parallelizing exact motif finding algorithms on multi-core
(
Springer Science+Business Media
, 2014 , Article)
The motif finding problem is one of the important and challenging problems in bioinformatics. A variety of sequential algorithms have been proposed to find exact motifs, but the running time is still not suitable due to ...
