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…
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…
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…
Asymmetry in cilia configuration induces hydrodynamic phase locking
Keiji Okumura, Seiya Nishikawa, Toshihiro Omori +2
To gain insight into the nature of biological synchronization at the microscopic scale, we here investigate the hydrodynamic synchronization between conically rotating objects term…
Orientational order in concentrated suspensions of spherical microswimmers
Arthur A. Evans, Takuji Ishikawa, Takami Yamaguchi +1
We use numerical simulations to probe the dynamics of concentrated suspensions of spherical microswimmers interacting hydrodynamically. Previous work in the dilute limit predicted…
Dancing Volvox: Hydrodynamic Bound States of Swimming Algae
Knut Drescher, Kyriacos C. Leptos, Idan Tuval +3
The spherical alga Volvox swims by means of flagella on thousands of surface somatic cells. This geometry and its large size make it a model organism for studying the fluid dynamic…
