triangulax: Differentiable Simulations with Triangular Meshes across Soft Matter Physics
Samuel Silliman, Qiwei Yu, Nikolas Claussen
Many physical and biological systems -foams, membranes, elastic shells, or tissue sheets- can be mathematically described as 2D surfaces. These surfaces can host complex dynamics,…
Dynamic Instabilities and Pattern Formation in Chemotactic Active Matter
Hongbo Zhao, Qiwei Yu, Andrej Košmrlj +1
Collectives of actively-moving particles can spontaneously segregate into dilute and dense phases through a process known as motility-induced phase separation (MIPS). This captivat…
Dissipation at limited resolutions: Power law and detection of hidden dissipative scales
Qiwei Yu, Pedro E. Harunari
Nonequilibrium systems, in particular living organisms, are maintained by irreversible transformations of energy that drive diverse functions. Quantifying their irreversibility, as…
Exact minimax entropy models of large-scale neuronal activity
Christopher W. Lynn, Qiwei Yu, Rich Pang +2
In the brain, fine-scale correlations combine to produce macroscopic patterns of activity. However, as experiments record from larger and larger populations, we approach a fundamen…
Time-reversal symmetry breaking in the chemosensory array reveals mechanisms for dissipation-enhanced cooperative sensing
David Hathcock, Qiwei Yu, Yuhai Tu
The Escherichia coli chemoreceptors form an extensive array that achieves cooperative and adaptive sensing of extracellular signals. The receptors control the activity of histidine…
Exactly solvable statistical physics models for large neuronal populations
Christopher W. Lynn, Qiwei Yu, Rich Pang +2
Maximum entropy methods provide a principled path connecting measurements of neural activity directly to statistical physics models, and this approach has been successful for popul…
Pattern formation of phase-separated lipid domains in bilayer membranes
Qiwei Yu, Andrej Košmrlj
Giant unilamellar vesicles (GUVs) composed of as few as three lipid species can phase separate into small-scale lipid domains with stripes and dots patterns. These patterns have be…
Resolving the binding-kinase discrepancy in bacterial chemotaxis: A nonequilibrium allosteric model and the role of energy dissipation
David Hathcock, Qiwei Yu, Bernardo A. Mello +3
The Escherichia coli chemotaxis signaling pathway has served as a model system for studying the adaptive sensing of environmental signals by large protein complexes. The chemorecep…
The energy cost for flocking of active spins: the cusped dissipation maximum at the flocking transition
Qiwei Yu, Yuhai Tu
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 t…
State-space renormalization group theory of nonequilibrium reaction networks: Exact solutions for hypercubic lattices in arbitrary dimensions
Qiwei Yu, Yuhai Tu
Nonequilibrium reaction networks (NRNs) underlie most biological functions. Despite their diverse dynamic properties, NRNs share the signature characteristics of persistent probabi…
The energy cost and optimal design of networks for biological discrimination
Qiwei Yu, Anatoly B. Kolomeisky, Oleg A. Igoshin
Many biological processes discriminate between correct and incorrect substrates through the kinetic proofreading mechanism which enables lower error at the cost of higher energy di…
Scaling of Energy Dissipation in Nonequilibrium Reaction Networks
Qiwei Yu, Dongliang Zhang, Yuhai Tu
The energy dissipation rate in a nonequilibirum reaction system can be determined by the reaction rates in the underlying reaction network. By developing a coarse-graining process…
