The level of toxin varies in time, favouring the growth of one strain under low drug concentration and the other strain when the toxin level is high.

Coupled environmental and demographic fluctuations shape the evolution of cooperative antimicrobial resistance

no code implementations • 12 Jul 2023 • Lluís Hernández-Navarro, Matthew Asker, Alastair M. Rucklidge, Mauro Mobilia

The inactivation of antimicrobials by resistant microbes can often be viewed as a cooperative behavior leading to the coexistence of resistant and sensitive cells in large populations and static environments.

Density Distribution in Soft Matter Crystals and Quasicrystals

The density distribution in solids is often represented as a sum of Gaussian peaks (or similar functions) centred on lattice sites or via a Fourier sum.

Deriving phase field crystal theory from dynamical density functional theory: consequences of the approximations

no code implementations • 7 Aug 2019 • Andrew J. Archer, Daniel J. Ratliff, Alastair M. Rucklidge, Priya Subramanian

Phase field crystal (PFC) theory, extensively used for modelling the structure of solids, can be derived from dynamical density functional theory (DDFT) via a sequence of approximations.
