Information transfer through a signaling module with feedback: a perturbative approach
Gerardo Aquino, Martin Zapotocky
Signal transduction in biological cells is effected by signaling pathways that typically include multiple feedback loops. Here we analyze information transfer through a prototypica…
A model of fasciculation and sorting in mixed populations of axons
Debasish Chaudhuri, Peter Borowski, Martin Zapotocky
We extend a recently proposed model (Chaudhuri et al., EPL 87, 20003 (2009)) aiming to describe the formation of fascicles of axons during neural development. The growing axons are…
Dynamics of path aggregation in the presence of turnover
Debasish Chaudhuri, Peter Borowski, P. K. Mohanty +1
We investigate the slow time scales that arise from aging of the paths during the process of path aggregation. This is studied using Monte-Carlo simulations of a model aiming to de…
Response and fluctuations of a two-state signaling module with feedback
Manoj Gopalakrishnan, Peter Borowski, Frank Jülicher +1
We study the stochastic kinetics of a signaling module consisting of a two-state stochastic point process with negative feedback. In the active state, a product is synthesized whic…
Topological defects and the short-distance behavior of the structure factor in nematic liquid crystals
Martin Zapotocky, Paul M. Goldbart
The scattering of light at large wave-vector magnitudes k in nematic systems containing topological defects is investigated theoretically. At large k the structure factor S(k) is d…
Dynamical Multiscaling in Quenched Skyrme Systems
Andrew D. Rutenberg, Wojtek J. Zakrzewski, Martin Zapotocky
Strong dynamical scaling violations exist in quenched two-dimensional systems with vector O(3) order parameters. These systems support non-singular topologically stable configurati…
