Dynamical and topological robustness of the mammalian cell cycle network: A reverse engineering approach (2013)
Journal Article

A common gene regulatory network model is the threshold Boolean network, used for example to model the Arabidopsis thaliana floral morphogenesis network or the fission yeast cell cycle network. In this paper, we analyze a logical model of the mammali... Read More about Dynamical and topological robustness of the mammalian cell cycle network: A reverse engineering approach.

Compressed sensing signal and data acquisition in wireless sensor networks and internet of things (2013)
Journal Article

The emerging compressed sensing (CS) theory can significantly reduce the number of sampling points that directly corresponds to the volume of data collected, which means that part of the redundant data is never acquired. It makes it possible to creat... Read More about Compressed sensing signal and data acquisition in wireless sensor networks and internet of things.

Transformation of an uncertain video search pipeline to a sketch-based visual analytics loop (2013)
Journal Article

Traditional sketch-based image or video search systems rely on machine learning concepts as their core technology. However, in many applications, machine learning alone is impractical since videos may not be semantically annotated sufficiently, there...
