Combinatorial decision-making driven by multicomponent surface condensates
Aidan Zentner, Ethan V. Halingstad, Cameron Chalk +4
Living organisms rely on molecular networks, such as gene circuits and signaling pathways, for information processing and robust decision-making in crowded, noisy environments. Rec…
Optimal Staged Self-Assembly of General Shapes
Cameron Chalk, Eric Martinez, Robert Schweller +3
We analyze the number of tile types , bins , and stages necessary to assemble squares and scaled shapes in the staged tile assembly model. For squar…
Universal Shape Replicators via Self-Assembly with Attractive and Repulsive Forces
Cameron Chalk, Erik D. Demaine, Martin L. Demaine +4
We show how to design a universal shape replicator in a self-assembly system with both attractive and repulsive forces. More precisely, we show that there is a universal set of con…
Programming and Training Rate-Independent Chemical Reaction Networks
Marko Vasic, Cameron Chalk, Austin Luchsinger +2
Embedding computation in biochemical environments incompatible with traditional electronics is expected to have wide-ranging impact in synthetic biology, medicine, nanofabrication…
Concentration Independent Random Number Generation in Tile Self-Assembly
Cameron Chalk, Bin Fu, Eric Martinez +2
In this paper we introduce the \emph{robust random number generation} problem where the goal is to design an abstract tile assembly system (aTAM system) whose terminal assemblies c…
Programming Substrate-Independent Kinetic Barriers with Thermodynamic Binding Networks
Keenan Breik, Cameron Chalk, David Doty +2
Engineering molecular systems that exhibit complex behavior requires the design of kinetic barriers. For example, an effective catalytic pathway must have a large barrier when the…
