Symmetry-Breaking Motility
Allen Lee, Ha Youn Lee, Mehran Kardar
Locomotion of bacteria by actin polymerization, and in vitro motion of spherical beads coated with a protein catalyzing polymerization, are examples of active motility. Starting fr…
Statistics of lines of natural images and implications for visual detection
Ha Youn Lee, Mehran Kardar
As borders between different regions, lines are an important element of natural images. Already at the level of the mammalian primary visual cortex (V1), neurons respond best to li…
Macroscopic equations for pattern formation in mixtures of microtubules and motors
Ha Youn Lee, Mehran Kardar
Inspired by patterns observed in mixtures of microtubules and molecular motors, we propose continuum equations for the evolution of motor density, and microtubule orientation. The…
Phase diagram of congested traffic flow: an empirical study
H. Y. Lee, H. -W. Lee, D. Kim
We analyze traffic data from a highway section containing one effective on-ramp. Based on two criteria, local velocity variation patterns and expansion (or nonexpansion) of congest…
