Research Notes: Gradient sensing in Bayesian chemotaxis
Andrea Auconi, Maja Novak, Benjamin M. Friedrich
Bayesian chemotaxis is an information-based target search problem inspired by biological chemotaxis. It is defined by a decision strategy coupled to the dynamic estimation of targe…
Surfing along concentration filaments: sperm chemotaxis in physiological shear flows
Steffen Lange, Benjamin M. Friedrich
Many motile biological cells navigate along concentration gradients of signaling molecules: This chemotaxis guides for instance sperm cells from marine invertebrates, which have to…
Chemokinetic scattering, trapping, and avoidance of active Brownian particles
Justus A. Kromer, Noelia de la Cruz, Benjamin M. Friedrich
We present a theory of chemokinetic search agents that regulate directional fluctuations according to distance from a target. A dynamic scattering effect reduces the probability to…
Limited Resources Induce Bistability in Microtubule Length Regulation
Matthias Rank, Aniruddha Mitra, Louis Reese +2
The availability of protein is an important factor for the determination of the size of the mitotic spindle. Involved in spindle-size regulation is kinesin-8, a molecular motor and…
Optimal decision making for sperm chemotaxis in the presence of noise
Justus A. Kromer, Steffen Märcker, Steffen Lange +2
For navigation, microscopic agents such as biological cells rely on noisy sensory input. In cells performing chemotaxis, such noise arises from the stochastic binding of signaling…
Load response of shape-changing microswimmers scales with their energy efficiency
Benjamin M. Friedrich
External forces acting on a microswimmer can feed back on its self-propulsion mechanism. We discuss this load response for a generic microswimmer that swims by cyclic shape changes…
Critical Point in Self-Organized Tissue Growth
Daniel Aguilar Hidalgo, Steffen Werner, Ortrud Wartlick +3
We present a theory of pattern formation in growing domains inspired by biological examples of tissue development. Gradients of signaling molecules regulate growth, while growth ch…
Droplet Ripening in Concentration Gradients
Christoph A. Weber, Chiu Fan Lee, Frank Jülicher
Living cells use phase separation and concentration gradients to organize chemical compartments in space. Here, we present a theoretical study of droplet dynamics in gradient syste…
Emergent stochastic oscillations and signal detection in tree networks of excitable elements
Justus Kromer, Ali Khaledi-Nasab, Lutz Schimansky-Geier +1
We study the stochastic dynamics of strongly-coupled excitable elements on a tree network. The peripheral nodes receive independent random inputs which may induce large spiking eve…
Sequential pattern formation governed by signaling gradients
David J. Jörg, Andrew C. Oates, Frank Jülicher
Rhythmic and sequential segmentation of the embryonic body plan is a vital developmental patterning process in all vertebrate species. However, a theoretical framework capturing th…
Stochastic resetting in backtrack recovery by RNA polymerases
Édgar Roldán, Ana Lisica, Daniel Sánchez-Taltavull +1
Transcription is a key process in gene expression, in which RNA polymerases produce a complementary RNA copy from a DNA template. RNA polymerization is frequently interrupted by ba…
