Multidimensional stationary probability distribution for interacting active particles.
TL;DR: In this paper, the stationary probability distribution for a non-equilibrium system composed by an arbitrary number of degrees of freedom that are subject to Gaussian colored noise and a conservative potential is derived.

Flagellated bacterial motility in polymer solutions
Vincent A. Martinez,Jana Schwarz-Linek,Mathias Reufer,Laurence G. Wilson,Alexander Morozov,Wilson C. K. Poon +5 more
TL;DR: The current standard model of how bacteria propelled by rotary helical flagella swim through concentrated polymer solutions postulates bacteria-sized pores, allowing them relative easy passage is overturned, and clear evidence for non-Newtonian effects in the highest-molecular-weight PVP solution is found.

Multidimensional Stationary Probability Distribution for Interacting Active Particles
TL;DR: The stationary probability distribution for a non-equilibrium system composed by an arbitrary number of degrees of freedom that are subject to Gaussian colored noise and a conservative potential is derived based on a multidimensional version of the Unified Colored Noise Approximation.
Journal ArticleDOI
Enhanced diffusion of nonswimmers in a three-dimensional bath of motile bacteria
TL;DR: It is shown that the diffusivity of nonmotile cells in a three-dimensional (3D) population of motile E. coli is enhanced by an amount proportional to the active cell flux, indicating that fluid entrainment is not relevant for diffusion enhancement in 3D.

John C. Crocker,David G. Grier +1 more
TL;DR: In this article, a set of image processing algorithms for extracting quantitative data from digitized video microscope images of colloidal suspensions is described, which can locate submicrometer spheres to within 10 nm in the focal plane and 150 nm in depth.

Chemotaxis in Escherichia coli analysed by Three-dimensional Tracking
Howard C. Berg,Douglas A. Brown +1 more
TL;DR: Chemotaxis toward amino-acids results from the suppression of directional changes which occur spontaneously in isotropic solutions.
