Remembrance of Tasks Past in Tunable Physical Networks
Purba Chatterjee, Marcelo Guzman, Andrea J. Liu
Sequential learning in physical networks is hindered by catastrophic forgetting, where training a new task erases solutions to earlier ones. We show that we can significantly enhan…
Hierarchical Loop Stabilization in Periodically Driven Elastic Networks
Purba Chatterjee, Eleni Katifori
Network remodeling, or adaptation, in the presence of periodically driven forcings has hereto remained largely unexplored, despite the fact that a broad class of biological transpo…
Pulsatile Driving Stabilizes Loops in Elastic Flow Networks
Purba Chatterjee, Sean Fancher, Eleni Katifori
Existing models of adaptation in biological flow networks consider their constituent vessels (e.g. veins and arteries) to be rigid, thus predicting a non physiological response whe…
DNA Supercoiling Drives a Transition between Collective Modes of Gene Synthesis
Purba Chatterjee, Nigel Goldenfeld, Sangjin Kim
Recent experiments showed that multiple copies of the molecular machine RNA polymerase (RNAP) can efficiently synthesize mRNA collectively in the active state of the promoter. Howe…
Three-body Interactions Drive the Transition to Polar Order in a Simple Flocking Model
Purba Chatterjee, Nigel Goldenfeld
A large class of mesoscopic or macroscopic flocking theories are coarse-grained from microscopic models that feature binary interactions as the chief aligning mechanism. However wh…
