Feedback Between Motion and Sensation Provides Nonlinear Boost in Run-and-tumble Navigation
Junjiajia Long, Steven W. Zucker, Thierry Emonet
Many organisms navigate gradients by alternating straight motions (runs) with random reorientations (tumbles), transiently suppressing tumbles whenever attractant signal increases.…
Adaptability of non-genetic diversity in bacterial chemotaxis
Nicholas W Frankel, William Pontius, Yann S Dufour +3
Bacterial chemotaxis systems are as diverse as the environments that bacteria inhabit, but how much environmental variation can cells tolerate with a single system? Diversification…
Limits of feedback control in bacterial chemotaxis
Yann S. Dufour, Xiongfei Fu, Luis Hernandez-Nunez +1
Inputs to signaling pathways can have complex statistics that depend on the environment and on the behavioral response to previous stimuli. Such behavioral feedback is particularly…
Adaptation dynamics in densely clustered chemoreceptors
William Pontius, Michael W. Sneddon, Thierry Emonet
In many sensory systems, transmembrane receptors are spatially organized in large clusters. Such arrangement may facilitate signal amplification and the integration of multiple sti…
Relationship between cellular response and behavioral variability in bacterial chemotaxis
Thierry Emonet, Philippe Cluzel
Bacterial chemotaxis in Escherichia coli is a canonical system for the study of signal transduction. A remarkable feature of this system is the coexistence of precise adaptation in…
Polarization of photospheric lines from turbulent dynamo simulations
J. Sánchez Almeida, T. Emonet, F. Cattaneo
We employ the magnetic and velocity fields from turbulent dynamo simulations to synthesize the polarization of a typical photospheric line. The synthetic Stokes profiles have prope…
The physics of twisted magnetic tubes rising in a stratified medium: two dimensional results
T. Emonet, F. Moreno-Insertis
The physics of a twisted magnetic flux tube rising in a stratified medium is studied using a numerical MHD code. The problem considered is fully compressible (no Boussinesq approxi…
