On the Information Required for Feedback Control
Matthew P. Leighton, Jose M. Betancourt, Thierry Emonet +2
Biological systems across scales, along with many engineering problems, must control noisy systems with limited information. Here we study information-limited feedback control of s…
Thermal fluctuations set fundamental limits on ion channel function
Jose M. Betancourt, Benjamin B. Machta
Voltage-gated ion channels are essential for propagating signals in neurons. Each channel senses the local membrane potential created by nearby ions. Fluctuations in these ions int…
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…
The Strength of Local Structures in Decentralized Network Formation
Jose M. Betancourt
I study dynamic network formation games in which agents meet stochastically and form links based on their valuation of the network. I show that these games can be represented in te…
Tractability and Phase Transitions in Endogenous Network Formation
Jose M. Betancourt
The dynamics of network formation are generally very complex, making the study of distributions over the space of networks often intractable. Under a condition called conservativen…
