Swimming, Feeding and Inversion of Multicellular Choanoflagellate Sheets
Lloyd Fung, Adam Konkol, Takuji Ishikawa +3
The recent discovery of the striking sheet-like multicellular choanoflagellate species that dynamically interconverts between two hemispherical forms of opposite…
Self-organisation of spermatozoa in bulk suspensions via unsteady elastohydrodynamic interactions
Nanami Taketoshi, Toshihiro Omori, Takuji Ishikawa
We developed a mechanical model of spermatozoal swimming in bulk suspensions. We traced the spatiotemporal elastohydrodynamic interactions and found that spermatozoa engaged in sel…
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…
Stability of dancing Volvox
Takuji Ishikawa, T. J. Pedley, K. Drescher +1
Biflagellate algal cells of the genus Volvox form spherical colonies that propel themselves, vertically upwards in still fluid, by the coordinated beating of thousands of flagella,…
Motility and Phototaxis of , the Simplest Differentiated Colonial Alga
Hélène de Maleprade, Frédéric Moisy, Takuji Ishikawa +1
Green algae of the lineage, spanning from unicellular to vastly larger , are models for the study of the evolution of multicellularity, flagella…
