Limits of feedback control in bacterial chemotaxis. [PDF]

open access: yesPLoS Computational Biology, 2014
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 important in navigation.

Siah2 control of T-regulatory cells limits anti-tumor immunity [PDF]

open access: yesNature Communications, 2020
The ubiquitin ligase Siah2 has been implicated in immune responses. Here, the authors show that Siah2 null immune cells have an increased inflammatory response to inoculated melanoma cells, along with a reduced number of infiltrating immunosuppressive ...

Probing the Limits to MicroRNA-Mediated Control of Gene Expression. [PDF]

open access: yesPLoS Computational Biology, 2016
According to the 'ceRNA hypothesis', microRNAs (miRNAs) may act as mediators of an effective positive interaction between long coding or non-coding RNA molecules, carrying significant potential implications for a variety of biological processes.

Symbiosis constraints: Strong mycobiont control limits nutrient response in lichens [PDF]

open access: yesEcology and Evolution, 2017
Symbioses such as lichens are potentially threatened by drastic environmental changes. We used the lichen Peltigera aphthosa—a symbiosis between a fungus (mycobiont), a green alga (Coccomyxa sp.), and N2‐fixing cyanobacteria (Nostoc sp.)—as a model ...

Position-Commanding Anti-Sway Controller for 2-D Overhead Cranes Under Velocity and Acceleration Constraints

open access: yesIEEE Access, 2023
This paper proposes an anti-sway controller for two-dimensional overhead cranes. The controller is of the position-commanding type, i.e., it sends position commands to the position-controlled trolley, and it uses the sensor information of the payload ...
