SDO: Subspace Deconflicting Operator for Multi-Adapter Composition
Zhongsheng Wang, Zhedong Lin, Qian Liu +2
Composing independently trained adapters within a shared diffusion backbone provides a modular approach to multi-character generation, but naive joint deployment often causes ident…
Active Model B from Mass-Conserving Reaction-Diffusion Systems
Davide Toffenetti, Beatrice Nettuno, Henrik Weyer +1
We show that the late-time dynamics of a minimal three-component mass-conserving reaction--diffusion system reduce to a scalar active field theory, Active Model B (AMB), in…
Pattern Formation Beyond Turing: Physical Principles of Mass-Conserving Reaction--Diffusion Systems
Erwin Frey, Henrik Weyer
Intracellular protein patterns govern essential cellular functions by dynamically redistributing proteins between membrane-bound and cytosolic states, conserving their total number…
Coarsening dynamics of chemotactic aggregates
Henrik Weyer, David Muramatsu, Erwin Frey
Auto-chemotaxis, the directed movement of cells along gradients in chemicals they secrete, is central to the formation of complex spatiotemporal patterns in biological systems. Sin…
Chemotaxis-induced phase separation
Henrik Weyer, David Muramatsu, Erwin Frey
Chemotaxis allows single cells to self-organize at the population level, as classically described by Keller-Segel models. We show that chemotactic aggregation can be understood usi…
Deciphering the Interface Laws of Turing Mixtures and Foams
Henrik Weyer, Tobias A. Roth, Erwin Frey
For cellular functions like division and polarization, protein pattern formation driven by NTPase cycles is a central spatial control strategy. Operating far from equilibrium, no g…
