Universal structures for adaptation in biochemical reaction networks

RP Araujo, LA Liotta - Nature Communications, 2023 - nature.com
At the molecular level, the evolution of life is driven by the generation and diversification of
adaptation mechanisms. A universal description of adaptation-capable chemical reaction …

Turing patterns on discrete topologies: from networks to higher-order structures

R Muolo, L Giambagli, H Nakao, D Fanelli… - Proceedings …, 2024 - royalsocietypublishing.org

[HTML][HTML] Control of diffusion-driven pattern formation behind a wave of competency

Y Liu, PK Maini, RE Baker - Physica D: Nonlinear Phenomena, 2022 - Elsevier
In certain biological contexts, such as the plumage patterns of birds and stripes on certain

Turing instability in quantum activator–inhibitor systems

Y Kato, H Nakao - Scientific Reports, 2022 - nature.com
Turing instability is a fundamental mechanism of nonequilibrium self-organization. However,
despite the universality of its essential mechanism, Turing instability has thus far been …

Amplitude equations for wave bifurcations in reaction–diffusion systems

E Villar-Sepúlveda, A Champneys - Nonlinearity, 2024 - iopscience.iop.org
A wave bifurcation is the counterpart to a Turing instability in reaction–diffusion systems, but
