  • This session solicits theoretical, simulation, and experimental studies that address aspects of both natural and synthetic biomolecule folding and assembly. (confex.com)
  • In this work, we develop a framework called SLIP ("Synthetic Landscape Inference for Proteins") for constructing synthetic landscapes with tunable difficulty based on Potts Models. (nips.cc)
