Response of cell behavior to small changes in parameter values | ||
---|---|---|
Parameter | Response to increase in value | Response to decrease in value |
σ _{ R } | Lesion expansion is abated sooner | Steadily approaches no EPO case |
σ _{ M } | Robust | Robust, until a_{ M }= 0 when no inflammation occurs |
σ _{ F } | Lesion abatement becomes less efficient | Lesion expansion is abated sooner |
σ _{ P } | Lesion expansion is abated sooner | Steadily approaches no EPO case |
Λ | Robust | Robust (must have Λ > 0) |
