'Infotaxis' as a strategy for searching without gradients

Article Abstract:

A search algorithm, called "infotaxis", is proposed that is designed to work without gradients and its efficiency is demonstrated by using a computational model of odor plume propagation and experimental data on mixing flows. The proposed search algorithm is relevant to the design of olfactory robots, but the general idea of infotaxis can be applied to any situation where competing demands of exploration and exploitation must be efficiently balanced.

Stochastic gene expression out-of-steady-state in the cyanobacterial circadian clock

Article Abstract:

The development and testing of common model for studying and forecasting stochastic expression of genes driven by the Synechococcus elongatus circadian clock is presented. It is found that the model is applicable to out-of-steady-state system and is required for knowing the fidelity of dynamic cellular systems.

Multistability in the lactose utilization network of Escherichia coli

Article Abstract:

Multistability refers to the capacity to achieve multiple internal states in response to a single set of external inputs of a switch. Herein, the phase diagram of the bistable lactose utilization network of Escherichia coli is presented.
