A nonequilibrium allosteric model for receptor-kinase complexes: The role of energy dissipation in chemotaxis signaling

D Hathcock, Q Yu, BA Mello, DN Amin… - Proceedings of the …, 2023 - National Acad Sciences
The Escherichia coli chemotaxis signaling pathway has served as a model system for the
adaptive sensing of environmental signals by large protein complexes. The chemoreceptors …

Energy cost for flocking of active spins: the cusped dissipation maximum at the flocking transition

Q Yu, Y Tu - Physical review letters, 2022 - APS
We study the energy cost of flocking in the active Ising model (AIM) and show that, besides
the energy cost for self-propelled motion, an additional energy dissipation is required to …

Thermodynamics for reduced models of chemical reactions by PEA and QSSA

L Peng, L Hong - Physical Review Research, 2024 - APS
The partial equilibrium approximation (PEA) and the quasi-steady-state approximation
(QSSA) are two classical methods for reducing complex macroscopic chemical reactions …

Scaling of entropy production under coarse graining in active disordered media

L Cocconi, G Salbreux, G Pruessner - Physical Review E, 2022 - APS
Entropy production plays a fundamental role in the study of nonequilibrium systems by
offering a quantitative handle on the degree of time-reversal symmetry breaking. It depends …

Dissipation at limited resolutions: Power law and detection of hidden dissipative scales

Q Yu, PE Harunari - arXiv preprint arXiv:2407.13707, 2024 - arxiv.org
Nonequilibrium systems, in particular living organisms, are maintained by irreversible
transformations of energy that drive diverse functions. Quantifying their irreversibility, as …
