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…
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…
Stochastic bubble dynamics in phase-separated scalar active matter
Mingqi Yan, Erwin Frey, Marcus Müller +1
In ABP systems, phase separation is accompanied by the emergence of vapor bubbles within liquid domains. Using large-scale particle-based simulations, we study the stochastic dynam…
