Cell-to-cell information at a feedback-induced bifurcation point
Amir Erez, Tommy A. Byrd, Michael Vennettilli +1
A ubiquitous way that cells share information is by exchanging molecules. Yet, the fundamental ways that this information exchange is influenced by intracellular dynamics remain un…
Biochemical feedback and its application to immune cells II: dynamics and critical slowing down
Tommy A. Byrd, Amir Erez, Robert M. Vogel +4
Near a bifurcation point, the response time of a system is expected to diverge due to the phenomenon of critical slowing down. We investigate critical slowing down in well-mixed st…
Universality of biochemical feedback and its application to immune cells
Amir Erez, Tommy A. Byrd, Robert M. Vogel +2
We map a class of well-mixed stochastic models of biochemical feedback in steady state to the mean-field Ising model near the critical point. The mapping provides an effective temp…
Dynamic sampling and information encoding in biochemical networks
Garrett D. Potter, Tommy A. Byrd, Andrew Mugler +1
Cells use biochemical networks to translate environmental information into intracellular responses. These responses can be highly dynamic, but how the information is encoded in the…
Matter, Energy, and Heat Transfer in a Classical Ballistic Atom Pump
Tommy A. Byrd, Kunal K. Das, Kevin A. Mitchell +2
A ballistic atom pump is a system containing two reservoirs of neutral atoms or molecules and a junction connecting them containing a localized time-varying potential. Atoms move t…
Ballistic atom pumps
Megan K. Ivory, Tommy A. Byrd, Andrew J. Pyle +4
We examine a classically-chaotic system consisting of two reservoirs of particles connected by a channel containing oscillating potential-energy barriers. We investigate whether su…
Communication shapes sensory response in multicellular networks
Garrett D Potter, Tommy A Byrd, Andrew Mugler +1
Collective sensing by interacting cells is observed in a variety of biological systems, and yet a quantitative understanding of how sensory information is collectively encoded is l…
Scattering by an oscillating barrier: quantum, classical, and semiclassical comparison
Tommy A. Byrd, Megan K. Ivory, Andrew J. Pyle +4
We present a detailed study of scattering by an amplitude-modulated potential barrier using three distinct physical frameworks: quantum, classical, and semiclassical. Classical phy…
