We show that the capacitive transduction of a MEMS device using a setup based on a microwave detection scheme achieves the measurement of the thermomechanical noise spectrum of a high-frequency (>10 MHz) high-stiffness (>10 5 N/m) resonator, reaching the outstanding displacement resolution of…

Modeling of ZigBee (IEEE 802.15.4) channel in rail environment for Intelligent Transport

Ulrich Biaou, Laïd Sadoudi, Michael Bocquet, Atika Rivenq

To deploy Wireless Sensor Networks (WSNs) in the railway transport, knowledge of signal propagation in this environment is required for the safety and the reliability of whole system. This calls to two domains of research. Firstly, the study of the propagation characteristics is necessary to…

Drift velocity versus electric field in < 110 > Si nanowires: Strong confinement effects

Jing Li, Gabriel Mugny, Yann-Michel Niquet, Christophe Delerue

We have performed atomistic simulations of the phonon-limited high field carrier transport in < 110 > Si nanowires with small diameter. The carrier drift velocities are obtained from a direct solution of the non-linear Boltzmann transport equation. The relationship between the drift velocity…

Kinetic proofreading of chromatin remodeling: from gene activation to gene repression and back

Raghvendra Singh, Guillaume Brysbaert, Marc Lensink, Fabrizio Cleri, Ralf Blossey

ATP-dependent chromatin remodeling is the active displacement of nucleosomes along or off DNA induced by chromatin remodeling complexes. This key process of gene regulation in eukaryote organisms has recently been argued to be controlled by a kinetic proofreading mechanism. In this paper we present…

Ambiguity function and Cramer-Rao bounds for standard and new modified Costas signals

Nadjah Touati, Charles Tatkeu, Thierry Chonavel, Yassin El Hillali, Atika Rivenq

The Cramer-Rao bound (CRB) gives a lower variance bound that an estimator can achieve. Presented is a mathematical approach to estimate it for specific radar signals, namely Costas signals and their modified versions. The modified versions design consists in widening Costas frequency hops and…

QAM-32/0.588 THz communication using electronic Schottky transceivers

Guillaume Ducournau, Pascal Szriftgiser, Denis Bacquet, Emilien Peytavit, Mohammed Zaknoune, Rédha Kassi, Jean-Francois Lampin

We report on THz communication system using vectorial modulations schemes above 500 GHz. Using schottky-based electronic technologies at 588 GHz, potentialities of high-level multi-carrier modulation schemes for wireless links are analyzed. The wireless link is composed of an emitter with sub-…
