High performance architecture design for large scale fibre-optic sensor arrays using distributed EDFAs and hybrid TDM/DWDM [PDF]

, 2013
A distributed amplified dense wavelength division multiplexing (DWDM) array architecture is presented for interferometric fibre optic sensor array systems. This architecture employs a distributed erbium doped fibre amplifier (EDFA) scheme to decrease the

Distinct difference configurations: multihop paths and key predistribution in sensor networks [PDF]

, 2010
A distinct difference configuration is a set of points in Z2 with the property that the vectors (difference vectors) connecting any two of the points are all distinct. Many specific examples of these configurations have been previously studied: the class

Highly-sensitive, biomimetic hair sensor arrays for sensing low-frequency air flows [PDF]

, 2009
In this paper, we report, to the best of our knowledge, the most sensitive artificial hair-based flow-sensor arrays operating in air, to date. Artificial hair sensors are bio-inspired from the cerci of crickets, one of nature’s best in sensing small air ...

The microbiome in human skin aging

FEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.
