Protein folding on rugged energy landscapes: Conformational diffusion on fractal networks
Gregg Lois, J. Blawzdziewicz, Corey S. O'Hern
We employ simulations of model proteins to study folding on rugged energy landscapes. We construct ``first-passage'' networks as the system transitions from unfolded to native stat…
Entropic origin of stress correlations in granular materials
Gregg Lois, Jie Zhang, Trushant S. Majmudar +4
We study the response of granular materials to external stress using experiment, simulation, and theory. We derive an entropic, Ginzburg-Landau functional that enforces mechanical…
A percolation model for slow dynamics in glass-forming materials
Gregg Lois, Jerzy Blawzdziewicz, Corey S. O'Hern
We identify a link between the glass transition and percolation of mobile regions in configuration space. We find that many hallmarks of glassy dynamics, for example stretched-expo…
Non-random coil behavior as a consequence of extensive PPII structure in the denatured state
Aitziber L. Cortajarena, Gregg Lois, Eilon Sherman +3
Unfolded proteins may contain native or non-native residual structure, which has important implications for the thermodynamics and kinetics of folding as well as for misfolding and…
Reliable protein folding on non-funneled energy landscapes: the free energy reaction path
Gregg Lois, Jerzy Blawzdziewicz, Corey S. O'Hern
A theoretical framework is developed to study the dynamics of protein folding. The key insight is that the search for the native protein conformation is influenced by the rate r at…
The jamming transition and new percolation universality classes in particulate systems with attraction
Gregg Lois, Jerzy Blawzdziewicz, Corey S. O'Hern
We numerically study the jamming transition in particulate systems with attraction by investigating their mechanical response at zero temperature. We find three regimes of mechanic…
