Fig. 1: Alternative formulations of cellular activity do not affect bulk active nematic turbulence.
From: Mitigating density fluctuations in particle-based active nematic simulations
Snapshots of local director field nC colored by the scalar order parameter SC for the four different formulations of cellular activity, with an activity parameter of α = 0.15 in a square periodic domain of size ℓsys = 50. “Part.” corresponds to particle-carried activity \({\alpha }_{{{{{{{\rm{C}}}}}}}}^{{{{{{{\rm{P}}}}}}}}\) (Eq. (6)); “Cell” to cell-carried activity \({\alpha }_{{{{{{{\rm{C}}}}}}}}^{{{{{{{\rm{C}}}}}}}}\) (Eq. (8)); “Mod. Part.” to modulated particle-carried activity \({\alpha }_{{{{{{{\rm{C}}}}}}}}^{{{{{{{\rm{MP}}}}}}}}\) (Eq. (12)); “Mod. Cell” to modulated cell-carried activity \({\alpha }_{{{{{{{\rm{C}}}}}}}}^{{{{{{{\rm{MC}}}}}}}}\) (Eq. (11)). Corresponds to frame 75 of Supplementary Movie 1.
