In the worst case, this increases time requirements to O(a × nm).
Moreover, since the main computations of EPIA are independent, they can be performed in parallel efficiently, with storage requirement O(n), where n is the number of the control points.
However, the requirement of O-GlcNAcylation for maintaining glucose homeostasis by regulating pancreatic β cell mass and function is unclear.
Compared to the original VF algorithm, VF2 lowers the memory requirements from O(n2) to O(n) with respect to the number of nodes in the graphs.
Requirements for O-fucose during imaginal development were evaluated by characterizing clones of cells expressing only Ofut1 R 245 A. These clones phenocopy fringe mutant clones, indicating that the absence of O-fucose is functionally equivalent to the absence of elongated O-fucose.
With the same argument as above, we can reduce the storage requirement of two layers to O(m · | V|) by considering only the sublist of S that consists of the nodes V. Hence, the whole procedure requires O(m · | V| + | E|) storage.
While this was initially taken to reflect a universal requirement for O-fucose on Notch, more recently a second function for OFUT1 was identified [ 10].
Lack of requirement for O-fucosylation is further supported by the absence of embryonic phenotypes in Gmd mutants, which lack all forms of fucosylation.
A simplified model, which assumes that the horizon of the material δ="O N-1), was prO N-1d to reduce the computational cost and memory requirement to O(N).
