We study the stochastic dynamics of a particle with two distinct motility states. Each one is characterized by two parameters: one represents the average speed and the other represents the persistence quantifying the tendency to maintain the current direction of motion. We consider a run-and-tumble process, which is a combination of an active fast motility mode (persistent motion) and a passive slow mode (diffusion). Assuming stochastic transitions between the two motility states, we derive an…

Run-and-tumble bacteria slowly approaching the diffusive regime.
It is found that for models (i), (ii), (iii), and (iv) the relaxation to diffusion can take much longer than the mean time between tumble events, evidencing the existence of large tails in the particle displacements.
How slowly do run-and-tumble bacteria approach the diffusive regime?
The run-and-tumble (RT) dynamics followed by bacterial swimmers gives rise first to a ballistic motion due to their persistence, and later, through consecutive tumbles, to a diffusive process. Here

Flocking with a q-fold discrete symmetry: Band-to-lane transition in the active Potts model.
A reorientation transition of the phase-separated profiles from transversal band motion to longitudinal lane formation is found, which is absent in the Vicsek model and the active Ising model.
Anomalous diffusion in a bench-scale pulsed fluidized bed.
Results indicate weak ergodicity breaking, which along with ageing characterizes the nonstationary and out-of-equilibrium dynamics of a bench-scale pulsed fluidized bed, which represents a weakly confined system.

This paper addresses symmetric Ito diffusions, with general position-dependent velocities and diffusion coefficients, that run over the real line. The paper establishes an explicit characterization
Distinct Speed and Direction Memories of Migrating Cells Diversify Their Possible Search Strategies
The results suggest that migrating cells can improve their search efficiency through the directional or speed persistence or the speed-direction correlation, especially in crowded environments.
Anomalous Subdiffusion in Living Cells: Bridging the Gap Between Experiments and Realistic Models Through Collaborative Challenges
A quick overview of the existing techniques used to analyze anomalous diffusion in cells are given and a collaborative challenge to foster the development of state-of-the-art analysis algorithms is proposed.
Amoeboid Cell Migration through Regular Arrays of Micropillars under Confinement
This work studies how migration and search efficiency of HL-60 cells differentiated into neutrophils in quasi two-dimensional environments are influenced by the lateral and vertical confinement and spatial arrangement of obstacles.
Treadmilling and dynamic protrusions in fire ant rafts
It is shown here that sustained shape evolution is permitted by the competing mechanisms of perpetual raft contraction aided by the transition of bulk structural ants to the free active layer and outward raft expansion owing to the deposition of free ants into the structural network at the edges, culminating in global treadmilling.


Persistent-random-walk approach to anomalous transport of self-propelled particles.
It is shown that the interplay of step length and turning angle distributions and self-propulsion produces various signs of anomalous diffusion at short time scales and asymptotically a normal diffusion behavior with a broad range of diffusion coefficients.
Anomalous diffusion of self-propelled particles in directed random environments.
It is proved the existence of different dynamical regimes of anomalous motion, and that the crossover times between these regimes as well as the asymptotic diffusion coefficient can be increased by several orders of magnitude within biologically relevant control parameter ranges.

The effect of crowding on the run-and-tumble dynamics of swimmers such as bacteria is studied using a discrete lattice model of mutually excluding particles that move with constant velocity along a
Anomalous diffusion in run-and-tumble motion.
A random walk scheme, consisting of alternating phases of regular Brownian motion and Lévy walks, is proposed as a model for run-and-tumble bacterial motion, and the long-time and short-time behavior of the mean squared displacement of the walker is obtained.
Run-and-pause dynamics of cytoskeletal motor proteins
This work presents an analytical model for the dynamics of self-propelled particles which undergo frequent pause phases, and addresses the role of initial conditions of motion on the resulting dynamics.
Averaged run-and-tumble walks
A random walk consisting of a run phase at constant speed interrupted by tumble events is analyzed and analytically solved for arbitrary time distributions. A general expression is given for the
Enhanced diffusion and anomalous transport of magnetic colloids driven above a two-state flashing potential.
A persistent random walk model is presented and numerical simulations are performed to demonstrate that the anomalous motion originates from the dynamic disorder in the structure of the magnetic lattice, induced by the slightly irregular shape of bubbles.
Anomalous transport in the crowded world of biological cells.
A large body of recent experimental evidence for anomalous transport in crowded biological media is reported on in cyto- and nucleoplasm as well as in cellular membranes, complemented by in vitro experiments where a variety of model systems mimic physiological crowding conditions.
Run-and-tumble dynamics of self-propelled particles in confinement
Run-and-tumble dynamics is a wide-spread mechanism of swimming bacteria. The accumulation of run-and-tumble microswimmers near impermeable surfaces is studied theoretically and numerically in the
Ergodic and nonergodic processes coexist in the plasma membrane as observed by single-molecule tracking
It is shown that an ergodic and a nonergodic process coexist in the plasma membrane and that when the cell is treated with drugs that inhibit actin polymerization, the diffusion pattern of Kv2.1 channels recovers ergodicity.
