Molecular Communications Pulse-Based Jamming Model for Bacterial Biofilm Suppression [PDF]

open access: yesIEEE Transactions on NanoBioscience, 2018
Studies have recently shown that the bacteria survivability within biofilms is responsible for the emergence of superbugs. The combat of bacterial infections, without enhancing its resistance to antibiotics, includes the use of nanoparticles to quench the quorum sensing of these biofilm-forming bacteria.

NOVEL JAMMING SUPPRESSION METHOD USING POLARIZATION SAR DATA [PDF]

open access: yesProgress In Electromagnetics Research C, 2014
Barrage and deceptive jamming can mask the synthetic aperture radar (SAR) signals and render SAR useless. In this paper, a novel jamming suppression method based on polarization SAR (PolSAR) is proposed. After range compression, the barrage jamming has a noise-like characteristic while the real echo and deceptive jamming are focused. According to this,
