Rotation-to-translation conversion by geometric asymmetry in viscoelastic fluids

Takuya Kobayashi, Hiroki Kitano, Ryoichi Yamamoto

Microscale locomotion in Newtonian fluids is constrained by kinematic reversibility. Here we show that viscoelasticity provides a distinct route: an achiral fore-aft asymmetric bod…

Viscotaxis of chiral microswimmer in viscosity gradients

Takuya Kobayashi, Ryoichi Yamamoto

Microswimmers display an intriguing ability to navigate through fluids with spatially varying viscosity, a behavior known as viscotaxis, which plays a crucial role in guiding their…

Steady Motions of Single Spherical Microswimmers in Non-Newtonian Fluids

Takuya Kobayashi, Ryoichi Yamamoto

In biological systems, microswimmers often propel themselves through complex media. However, many aspects of swimming mechanisms in non-Newtonian fluids remain unclear. This study…

Nash epidemics

Simon K. Schnyder, John J. Molina, Ryoichi Yamamoto +1

Faced with a dangerous epidemic humans will spontaneously social distance to reduce their risk of infection at a socio-economic cost. Compartmentalised epidemic models have been ex…

Propulsion of a chiral swimmer in viscoelastic fluids

Takuya Kobayashi, John J. Molina, Ryoichi Yamamoto

Microswimmers often use chirality to generate translational movement from rotation motion, exhibiting distinct behaviors in complex fluids compared to simple Newtonian fluids. Howe…

Rational social distancing in epidemics with uncertain vaccination timing

Simon K. Schnyder, John J. Molina, Ryoichi Yamamoto +1

During epidemics people may reduce their social and economic activity to lower their risk of infection. Such social distancing strategies will depend on information about the cours…
