The bidomain model is the standard model for cardiac electrophysiology. In this paper, we investigate the instability and asymptotic behavior of planar fronts and planar pulses of…
Long-Time Behavior of a PDE Replicator Equation for Multilevel Selection in Group-Structured Populations
Daniel B. Cooney, Yoichiro Mori
In many biological systems, natural selection acts simultaneously on multiple levels of organization. This scenario typically presents an evolutionary conflict between the incentiv…
A single-layer based numerical method for the slender body boundary value problem
William H. Mitchell, Henry G. Bell, Yoichiro Mori +2
Fluid flows containing dilute or dense suspensions of thin fibers are widespread in biological and industrial processes. To describe the motion of a thin immersed fiber, or to desc…

The Peskin problem models the dynamics of a closed elastic filament immersed in an incompressible fluid. In this paper, we consider the case when the inner and outer viscosities ar…
Evolution of prosocial behavior in multilayer populations
Qi Su, Alex McAvoy, Yoichiro Mori +1
Human societies include diverse social relationships. Friends, family, business colleagues, and online contacts can all contribute to one's social life. Individuals may behave diff…
Accuracy of slender body theory in approximating force exerted by thin fiber on viscous fluid
Yoichiro Mori, Laurel Ohm
We consider the accuracy of slender body theory in approximating the force exerted by a thin fiber on the surrounding viscous fluid when the fiber velocity is prescribed. We term t…
