Topotaxis of Active Particles Induced by Spatially Heterogeneous Sliding along Obstacles
Zeinab Sadjadi, Heiko Rieger
Many biological active agents respond to gradients of environmental cues by redirecting their motion. Besides the well-studied prominent examples such as photo- and chemotaxis, the…
Kinematics of Persistent Random Walkers with Two Distinct Modes of Motion
M. Reza Shaebani, Heiko Rieger, Zeinab Sadjadi
We study the stochastic motion of active particles that undergo spontaneous transitions between two distinct modes of motion. Each mode is characterized by a velocity distribution…
Migration of Cytotoxic T Lymphocytes in 3D Collagen Matrices
Z. Sadjadi, R. Zhao, M. Hoth +2
To fulfill their killing functions, cytotoxic T lymphocytes (CTLs) need to migrate to search for their target cells in complex biological microenvironments, a key component of whic…
Orientational Memory of Active Particles in Multistate Non-Markovian Processes
Zeinab Sadjadi, M. Reza Shaebani
The orientational memory of particles can serve as an effective measure of diffusivity, spreading, and search efficiency in complex stochastic processes. We develop a theoretical f…
Persistent-random-walk approach to anomalous transport of self-propelled particles
Zeinab Sadjadi, M. Reza Shaebani, Heiko Rieger +1
The motion of self-propelled particles is modeled as a persistent random walk. An analytical framework is developed that allows the derivation of exact expressions for the time evo…
Anomalous Diffusion of Self-Propelled Particles in Directed Random Environments
M. Reza Shaebani, Zeinab Sadjadi, Igor M. Sokolov +2
We theoretically study the transport properties of self-propelled particles on complex structures, such as motor proteins on filament networks. A general master equation formalism…
