Law of Localization in Chemical Reaction Networks.
In living cells, chemical reactions are connected by sharing their products and substrates, and form complex networks, e.g., metabolic pathways. Here we developed a theory to predict the sensitivity, i.e., the responses of concentrations and fluxes to perturbations of enzymes, from network structure alone. Nonzero response patterns turn out to exhibit two characteristic features, localization a...
متن کاملChemical source localization in real environments integrating chemical concentrations in a probabilistic plume mapping approach
Chemical plume source localization algorithms can be classified either as reactive plume tracking or gas distribution mapping approaches [1-2]. Here, we focus on gas distribution mapping methods where the robot does not need to track the plume to find the source and can be used for other tasks [3]. Probabilistic mapping approaches have been previously applied to real-world data successfully; e....
متن کاملChemical Source Localization Fusing Concentration Information in the Presence of Chemical Background Noise †
We present the estimation of a likelihood map for the location of the source of a chemical plume dispersed under atmospheric turbulence under uniform wind conditions. The main contribution of this work is to extend previous proposals based on Bayesian inference with binary detections to the use of concentration information while at the same time being robust against the presence of background c...
متن کاملEnsemble-based Chemical Data Assimilation II: Covariance Localization
Data assimilation is the process of integrating observational data and model predictions to obtain an optimal representation of the state of the atmosphere. As more chemical observations in the troposphere are becoming available, chemical data assimilation is expected to play an essential role in air quality forecasting, similar to the role it has in numerical weather prediction. Considerable p...
متن کاملChemical Source Localization using Mobile Robots in Indoor Arena
This paper presents a virtual-physics force based control strategy for swarm robotic chemical source localization. The control force includes: structure formation force, goal force, and obstacle avoidant force. For swarm formation, the robots maintain the regular polygon formation and a virtual robot is located at the center of the polygon. The motion of the virtual robot depends on the goal fo...
