On the optimal sampling design for the Graph Total Variation decoder: recovering piecewise-constant graph signals from a few vertex measurements
Rodrigo Cerqueira Gonzalez Pena
Compressed Sensing teaches us that measurements can be traded for offline computation if the signal being sensed has a simple enough representation. Proper decoders can exactly recover the high-dimensional signal of interest from a lower-dimensional vector ...
EPFL2020Convergent beam electron diffraction of multilayer Van der Waals structures
Convergent beam electron diffraction is routinely applied for studying deformation and local strain in thick crystals by matching the crystal structure to the observed intensity distributions. Recently, it has been demonstrated that CBED can be applied for ...
2020Stability of spatial patterns in water chemistry across temperate ecoregions
Human activity has polluted freshwater ecosystems across the planet, harming biodiversity, human health, and the economy. Improving water quality depends on identifying pollutant sources in river networks, but pollutant concentrations fluctuate in time. Co ...
IOP PUBLISHING LTD2019Short cavity InGaN-based laser diodes with cavity length below 300 mu m
Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Hua Zhang, Denis Martin, Ching-Wen Shih
We report on a practical method for developing InGaN-based edge emitting laser diodes of cavity length down to 45 mu m. Samples consisting of one uncoated cleaved facet and one etched facet coated with a high-reflectivity (HR) dielectric distributed Bragg ...
