Slower swimming promotes chemotactic encounters between bacteria and small phytoplankton
Riccardo Foffi, Douglas R. Brumley, François Peaudecerf +2
Chemotaxis enables marine bacteria to increase encounters with phytoplankton cells by reducing their search times, provided that bacteria detect noisy chemical gradients around phy…
Point torque representations of ciliary flows
Siluvai Antony Selvan, Peter W. Duck, Draga Pihler-Puzović +1
Ciliary flows are generated by a vast array of eukaryotic organisms, from unicellular algae to mammals, and occur in a range of different geometrical configurations. We employ a po…
Pairwise scattering and bound states of spherical microorganisms
C. Darveniza, T. Ishikawa, T. J. Pedley +1
The dynamic interactions between pairs of swimming microorganisms underpin the collective behaviour of larger suspensions, but accurately calculating pairwise collisions has typica…
Rheology of a concentrated suspension of spherical squirmers: monolayer in simple shear flow
T. Ishikawa, D. R. Brumley, T. J. Pedley
A concentrated, vertical monolayer of identical spherical squirmers, which may be bottom-heavy, and which are subjected to a linear shear flow, is modelled computationally by two d…
Bacteria push the limits of chemotactic precision to navigate dynamic chemical gradients
Douglas R. Brumley, Francesco Carrara, Andrew M. Hein +3
Ephemeral aggregations of bacteria are ubiquitous in the environment, where they serve as hotbeds of metabolic activity, nutrient cycling, and horizontal gene transfer. In many cas…
Stability of arrays of bottom-heavy spherical squirmers
Douglas R. Brumley, Timothy J. Pedley
The incessant swimming motion of microbes in dense suspensions can give rise to striking collective motions and coherent structures. However, theoretical investigations of these st…
