A novel cloud approach for connected vehicles

Geoffrey Wilhelm, Marwane Ayaida, Hacène Fouchal

Cooperative intelligent transport systems (C-ITSs) are being deployed all around the world. Shortly, in addition to vehicles, bicycles, pedestrians, buses, and all moving equipment will be compatible with C-ITS. These systems are connected through wireless local area networks based on WIFI IEEE 802…

Friction dynamics of elasto-inertial turbulence in Taylor–Couette flow of viscoelastic fluids

Masoud Moazzen, Tom Lacassagne, Vincent Thomy, S. Amir Bahrani

Dynamic properties of elasto-inertial turbulence (EIT) are studied in a Taylor–Couette geometry. EIT is a chaotic flow state that develops upon both non-negligible inertia and viscoelasticity. A combination of direct flow visualization and torque measurement allows to verify the earlier onset of…

Development of nanomaterial enabling highly sensitive SALDI‐MS peptide analysis

Aline Cournut, Ioana Silvia Hosu, Flavie Braud, Paul Moustiez, Yannick Coffinier, Christine Enjalbal, Claudia Bich

RationaleSALDI-MS (Surface-Assisted Laser Desorption/Ionisation Mass Spectrometry) is an approach derived from MALDI-MS (Matrix-Assisted Laser Desorption/Ionisation) which overcomes the drawbacks associated with the use of organic matrices required to co-crystallize with the analytes. Indeed,…

Nanoscale electronic transport at graphene/pentacene van der Waals interface

Michel Daher Mansour, Jacopo Oswald, Davide Beretta, Michael Stiefe, Roman Furrer, Michel Calame, Dominique Vuillaume

We report a study on the relationship between structure and electron transport properties of nanoscale graphene/pentacene interfaces. We fabricated graphene/pentacene interfaces from 10-30 nm thick needle-like pentacene nanostructures down to two-three layers (2L-3L) dendritic pentacene islands,…

Epitaxial La_0.5Sr_0.5MnO_3‐δ Bipolar Memristive Devices with Tunable and Stable Multilevel States

Carlos Moncasi, Gauthier Lefèvre, Quentin Villeger, Laetitia Rapenne, Thoai‐khanh Khuu, Fabrice Wilhelm, Andrei Rogalev, Carmen Jiménez, Mónica Burriel

Valence change memories are novel data storage devices in which the resistance is determined by a reversible redox reaction triggered by voltage. The oxygen content and mobility within the active materials of these devices play a crucial role in their performance. Therefore, materials which present…

Quantum Computing for solving the 3SAT problem by reduction to the MIS combinatorial optimization problem

Samuel Deleplanque

This work tries to anticipate the main issues related to the D-Wave machines topology for solving the 3Sat problem. The polynomial reduction to the Maximum Independent Set Problem (MIS) is employed for solving a 3Sat instance to furnish a less dense graph to the machine. These analog quantum…

Infinite ergodicity in generalized geometric Brownian motions with nonlinear drift

Stefano Giordano, Fabrizio Cleri, Ralf Blossey

Geometric Brownian motion is an exemplary stochastic processes obeying multiplicative noise, with widespread applications in several fields, e.g. in finance, in physics and biology. The definition of the process depends crucially on the interpretation of the stochastic integrals which involves the…
