We numerically study a one-dimensional system of self-propelled particles on a lattice where the state of each particle is given by its moving direction (left or right) and its position on the lattice. Particles obey run-and-tumble dynamics and interact with each other via excluded volume. Besides particle motion, we consider the collective motion of aggregates towards the direction dictated by the majority of their constituents (in a momentum-conservation manner). Our results show that this…

Universal scaling in active single-file dynamics.
TLDR
A universal scaling behavior in the single-file dynamics of interacting active particles is revealed, including multiple peaks that are reminiscent of particle clustering induced by effective attractive interactions, while the dynamical variant shows non-diffusive scaling.

"J."
however (for it was the literal soul of the life of the Redeemer, John xv. io), is the peculiar token of fellowship with the Redeemer. That love to God (what is meant here is not God’s love to men)
I and i
TLDR
There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
