Discrete turn strategies emerge in information-limited navigation
Jose M. Betancourt, Matthew P. Leighton, Thierry Emonet +2
Navigation up a smooth sensory gradient is one of the simplest behavioural tasks, and some organisms solve it by making continuous adjustments to their course. Bacteria instead emp…
In-vivo entropy production of A. subaru
Yu Fu, Emmy Dobson, Benjamin B. Machta +1
Entropy production is often used as a proxy for energy consumption of a non-equilibrium system. Lower bounds can be estimated from coarse-grained observations, and this has been do…
On the Analytic Origin of Two Species of Cochlear Eigenmodes
Asheesh S. Momi, Isabella R. Graf, Michael C. Abbott +1
After entering the ear, sound waves propagate as surface waves along the cochlea's basilar membrane. In recent work, we showed numerically that the system supports two types of mod…
Hair cells in the cochlea must tune resonant modes to the edge of instability without destabilizing collective modes
Asheesh S. Momi, Michael C. Abbott, Julian Rubinfien +2
Sound produces surface waves along the cochlea's basilar membrane. To achieve the ear's astonishing frequency resolution and sensitivity to faint sounds, dissipation in the cochlea…
