An Investigation of the Channel Capacity of Bacterial Chemotactic Sensors for Low Chemoattractant Concentrations
Ziyi Cui, Sarah Marzen
Bacterial chemotactic sensing converts noisy chemical signals into running and tumbling. We analyze the static sensing limits of mixed Tar/Tsr chemoreceptor clusters in individual…

Predictions for and lack of maximal information transmission in the neuromuscular junction
Eitan Goldfein, Sarah Marzen
A key question in theoretical biology is how effectively biological systems preserve information about their inputs while operating under physical and functional constraints. We ex…

Transformers represent belief state geometry in their residual stream
Adam S. Shai, Sarah E. Marzen, Lucas Teixeira +2
What computational structure are we building into large language models when we train them on next-token prediction? Here, we present evidence that this structure is given by the m…
