Iron minerals within specific microfossil morphospecies of the 1.88 Ga Gunflint Formation

Kevin Lepot, Ahmed Addad, Andrew H. Knoll, Jian Wang, David Troadec, Armand Béché, Emmanuelle J. Javaux

Problematic microfossils dominate the palaeontological record between the Great Oxidation Event 2.4 billion years ago (Ga) and the last Palaeoproterozoic iron formations, deposited 500-600 million years later. These fossils are often associated with iron-rich sedimentary rocks, but their affinities...

Ambipolar spin diffusion in p-type GaAs: A case where spin diffuses more than charge

Fabian Cadiz, V. Notot, J. Filipovic, D. Paget, C. Weber, L. Martinelli, A. Rowe, S. Arscott

We investigate the diffusion of charge and spin at 15 K in p-type GaAs, combining transient-grating and energy-resolved microluminescence measurements to cover a broad range of photoelectron density. At very low optical power, in a unipolar nondegenerate regime, charge and spin diffuse at the same...

Quantitative determination of small dielectric and loss tangent contrasts in liquids

Hind Bakli, Kamel Haddadi

Accurate measurement of dielectric constant and loss tangent in liquid media in the frequency range 2-6 GHz is proposed in this paper. The measurement set-up is based on an open-ended coaxial probe instrumented with a home-made microwave interferometer. The interferometer is used to match the...

Pillar-type acoustic metasurface

Yabin Jin, Bernard Bonello, Rayisa P. Moiseyenko, Yan Pennec, Olga Boyko, Bahram Djafari-Rouhani

We theoretically investigate acoustic metasurfaces consisting of either a single pillar or a line of identical pillars on a thin plate, and we report on the dependence on the geometrical parameters of both the monopolar compressional and dipolar bending modes. We show that for specific dimensions...

IEEE 802.11n Communications in the Presence of Frequency-Sweeping Interference Signals

Virginie Deniau, Christophe Gransart, Grecia Romero, Eric Pierre Simon, Joumana Farah

This paper presents an analysis of the impact of intentional electromagnetic (EM) interferences on the performance of Wi-Fi communications. The goal is to analyze the susceptibility of orthogonal frequency-division multiplexing (OFDM) signals and to understand how certain parameters of the..., Cet article présente une analyse de l'impact des interférences électromagnétiques intentionnelles (IEMI) sur la performance des communications Wi-Fi. L'objectif est d'analyser la susceptibilité des signaux de OFDM (Orthogonal Frequency Division Multiplex ) et de comprendre comment...

A 4-fJ/spike artificial neuron in 65 nm CMOS technology

Ilias Sourikopoulos, Sara Hedayat, Christophe Loyez, Francois Danneville, Virginie Hoel, Eric Mercier, A. Cappy

As Moore's law reaches its end, traditional computing technology based on the Von Neumann architecture is facing fundamental limits. Among them is poor energy efficiency. This situation motivates the investigation of different processing information paradigms, such as the use of spiking neural...

Microstructuration of Silicon Surfaces Using Nanoporous Gold Electrodes

E Torralba, Mathieu Halbwax, T El Assimi, V. Magnin, Joseph Harari, Jean-Pierre Vilcot, Sylvain Le Gall, Raphaël Lachaume, C Cachet-Vivier, Stéphane Bastide

Etching is a key process in the fabrication of silicon (Si) microstructures that are essential for several component families used in microelectronics, photonics and photovoltaics, among others. A large variety of microstructuring technologies exists nowadays (e.g. wet/dry etchings based on photo/...
