A new spectral index for the extraction of built-up land features from Landsat 8 satellite imagery

Rafik Bouhennache, Toufik Bouden, Abdelmalik Taleb-Ahmed, Abbas Cheddad

Extracting built-up areas from remote sensing data like Landsat 8 satellite is a challenge. We have investigated it by proposing a new index referred as built-up land features extraction index (BLFEI). The BLFEI index takes advantage of its simplicity and good separability between the four major…

Développement d'un microsystème étirable pour l'étude de l'activité électrique de cellules neuronales sous contrainte mécanique, Development of a stretchable microsystem for the study of electronic activity of neuronal cells under mechanical strain

Tiffany Baëtens

Alors que 50 million de personnes souffrent de traumatismes crâniens chaque année dans le monde entier, le choc (stress mécanique externe), engendré à cette occasion sur le réseau neuronal, peut amener à l’apparition de lésions cérébrales traumatiques. A moyen et long termes, ce processus peut…, 50 million people suffer from head trauma each year worldwide. The shock (external mechanical stress) acting on neural networks insided the brain can lead to the appearance of traumatic brain injuries (TBI). In the short term and long term, this process can lead to neuroinflammation and the…

Single-electron tunneling PbS/InP neuromorphic computing building blocks

P F Jarschel, J H Kim, Louis Biadala, Maxime Berthe, Yannick Lambert, R M Osgood, G. Patriarche, B. Grandidier, Jimmy Xu

We study single-electron tunneling (SET) characteristics in crystalline PbS/InP junctions, that exhibit single-electron Coulomb-blockade staircases along with memory and memory-fading behaviors. This gives rise to both short-term and long-term plasticities as well as a convenient non-linear…

[Invited] Hydrogels and Other Ionic Conductors in ‘Piezo-Ionic’ Sensors, Actuators and Electrochemical Devices

John D.W. Madden, Yuta Dobashi, Mirza Sarwar, Dickson Yao, Saeedeh Ebrahimi Takalloo, Claire Preston, Tan Ngoc Nguyen, Justin Wyss, Bertille Dupont, Yael Petel, Carl Michal, Cedric Plesse, Giao Tran-Minh Nguyen, Frederic Vidal, Eric Cattan, Sébastien Grondel, David Shepherd, Geoffrey Spinks

Ionic conductors offer exciting device possibilities, particularly with the advent of highly extensible and easily synthesized hydrogels. Following on from recent work on hydrogel “ionic skin”, ‘piezo-ionic’ sensors and ionic artificial muscle, we present example ionic devices, including…

Iuliacumite: A Novel Chemical Short-Range Order in a Two-Dimensional Wurtzite Single Monolayer InAs 1– x Sb x Shell on InAs Nanowires

M. Schnedler, T. Xu, Isabelle Lefebvre, J.-P. Nys, S R Plissard, Maxime Berthe, H. Eisele, R. E Dunin-Borkowski, Ph. Ebert, B. Grandidier

A chemical short range order is found in single monolayer InAs 1-x Sb x shells, which inherit a wurtzite structure from the underlying InAs nanowire, instead of crystallizing in the energetically preferred zincblende structure. The chemical order is characterized by an anti-correlation ordering…

Intrinsic versus shape anisotropy in micro-structured magnetostrictive thin films for magnetic surface acoustic wave sensors

Harshad Mishra, Michel Hehn, Daniel Lacour, Omar Elmazria, Nicolas Tiercelin, Hamid Mjahed, Karine Dumesnil, Sébastien Petit, Vincent Polewczyk, Abdelkrim Talbi, Olivier Bou Matar, Sami Hage-Ali

This work aims at studying the interaction between surface acoustic waves (SAW) and micro-structured magnetostrictive layers under a magnetic field with a perspective to develop magnetic field sensors. The impact of the competition between the strong intrinsic magnetic anisotropy of the magnetic…
