Combining audio and visual displays to highlight temporal and spatial seismic patterns

Arthur Paté, Gaspard Farge, Benjamin Holtzman, Anna Barth, Piero Poli, Lapo Boschi, Leif Karlstrom

Data visualization, and to a lesser extent data sonification, are classic tools to the scientific community. However, these two approaches are very rarely combined, although they are highly complementary: our visual system is good at recognizing spatial patterns, whereas our auditory system is…

A Gradual Resource Allocation Technique for Massive MIMO-NOMA

Eric Pierre Simon, Joumana Farah, Pierre Laly, Gauthier Delbarre

In this paper, a new perspective for channel allocation and user pairing is proposed for a crowded downlink system using massive multiple-input multiple-output (MIMO), non-orthogonal multiple access (NOMA), and Zero-forcing (ZF) beamforming. The proposed user clustering technique allocates users to…

Characterization of IEEE 802.11 communications and detection of low power jamming attacks in noncontrolled environment based on a clustering study

Jonathan Villain, Virginie Deniau, Christophe Gransart, Anthony Fleury, Eric Pierre Simon

Wireless connections are more and more used in different applications and in public areas for services to consumers but also for handling (sometimes) sensitive communications (for instance in railway systems or for remote video monitoring systems). Such systems can have to face different kind of…

Bio‐Inspired Adaptive Sensing through Electropolymerization of Organic Electrochemical Transistors

Mahdi Ghazal, Michel Daher Mansour, Corentin Scholaert, Thomas Dargent, Yannick Coffinier, Sébastien Pecqueur, F. Alibart

Organic electrochemical transistors are considered today as a key technology to interact with a biological medium through their intrinsic ionic-electronic coupling. In this paper, the authors show how this coupling can be finely tuned (in operando) post-microfabrication via the…

Sensitivity-Bandwidth Optimization of PMUT with Acoustical Matching Using Finite Element Method

Le-Ming He, Wei-Jiang Xu, Yan Wang, Jia Zhou, Jun-Yan Ren

A new model in finite element method to study round-trip performance of piezoelectric micromachined ultrasonic transducers (pMUTs) is established. Most studies on the performance of pMUT are based only on the transmission sensibility, but the reception capacity is as much important as the…

The holy grail of pyrene-based surface ligands on the sensitivity of graphene-based field effect transistors

Vladyslav Mishyn, Adrien Hugo, Teresa Rodrigues, Patrik Aspermair, Henri Happy, Leonel Marques, Charlotte Hurot, Riadh Othmen, Vincent Bouchiat, Rabah Boukherroub, Wolfgang Knoll, Sabine Szunerits

Graphene has received intensive research interest due to its remarkable charge mobility, and the efforts in the use of graphene-based field effect transistors (GFETs) for the sensing of biological biomarkers is on the rise. Because of the high non-specific protein adsorption on graphene, well-…

Investigation of Lattice Plasmon Modes in 2D Arrays of Au Nanoantennas

Antonio Ferraro, Joseph Marae Djouda, Giuseppe Emanuele Lio, Gaëtan Lévêque, Pierre-Michel Adam, Cesare Paolo Umeton, Thomas Maurer, Roberto Caputo

The coupling of gold nanoantennas (AuNAs) in the arrangement of monomers in bidimensional gratings is investigated both experimentally and numerically. The influence of edge diffraction, corresponding to the grazing propagation of specific diffracted orders, and the dependence of grating parameters…

Enabling User Relaying In MCM-NOMA Under Doubly Selective Channels Using Iterative Interference Cancellation Schemes For Wireless IoT Networks

Anis Amazigh Hamza, Iyad Dayoub, Ihsen Alouani, Abderrahmane Amrouche

Cell-edge users of future cellular internet of things (IoT) sensor networks can suffer from extremely severe channel conditions, especially under mobility with high speeds, i.e., doubly selective channels. This paper presents a performance improvement method for IoT cell-edge users downlink…

Impact of colistin and colistin-loaded on alginate nanoparticles on pigs infected with a colistin-resistant enterotoxigenic Escherichia coli strain

Djamel Drider, Rabah Boukherroub, Laetitia Le Devendec, Yanath Belguesmia, Noura Hazime, Gwenaelle Mourand, Frédéric Paboeuf, Isabelle Kempf

Colistin is frequently used for the control of post-weaning diarrhoea in pigs. Colistin resistance caused by plasmidic genes is a public health issue. We evaluated, in experimental animal facilities, whether free colistin or colistin-loaded on alginate nanoparticles (colistin/Alg NPs) could select…

Short bends using curved mirrors in silicon waveguides for terahertz waves

Mattias Verstuyft, Elias Akiki, Mathias Vanwolleghem, Guillaume Ducournau, Jean-Francois Lampin, Benjamin Walter, Fuanki Bavedila, Édouard Lebouvier, Marc Faucher, Bart Kuyken

Dielectric waveguides are capable of confining and guiding terahertz waves along sub-wavelength sized structures. A small feature size allows for a denser integration of different photonic components such as modulators, beam-splitters, wavelength (de)multiplexers and more. The integration of…
