To complete the proof, we first show that the prey ((x t))) is weakly persistent, that is to say, (limsup_{trightarrow infty}x t)>0).
Then system (4) is uniformly persistent, that is, there exists a positive constant (epsilon>0) such that every solution ((S t), I t)) ) of (4) satisfies (liminf_{ttoinfty} I t) geqepsilon).
This earlier study was based on microarrays and identified SNEPs (termed ' labile') that were significantly affected by the treatment/recovery protocol and SNEPs (termed ' persistent') that remained different between the strains.
This study suggests that the more persistent that patients are and the longer that they persist with treatment the better they will perform on cognitive, global, and functional outcomes.
