Growth temperature effect on physical and mechanical properties of nitrogen rich InN epilayers

Z. Benzarti, T. Sekrafi, A. Khalfallah, Zahia Bougrioua, D. Vignaud, M. Evaristo, A. Cavaleiro

A set of N-polar InN epilayers has been grown at different temperatures by plasma-assisted molecular beam epitaxy (PA-MBE) on GaN/AlN/Al2O3(0001) templates. The purpose is to understand how the variation of crucial factor, such as the temperature, impacts the growth process and the resulting…

An advanced ageing methodology for robustness assessment of normally-off AlGaN/GaN HEMT

F. Albany, A. Curutchet, N. Labat, F. Lecourt, E. Walasiak, H. Maher, Y. Cordier, N. Defrance, N. Malbert

The semi-on-state reliability of normally-off AlGaN/GaN high electron mobility transistor fabricated by fluorine ion plasma implantation technology is reported, focusing on an advanced dc step-stress methodology. By inserting a non-stressful fixed-bias step between each stress step, a reliable in-…

The Map3k12 (Dlk)/JNK3 signaling pathway is required for pancreatic beta-cell proliferation during postnatal development

Mathie Tenenbaum, Valérie Plaisance, Raphael Boutry, Valérie Pawlowski, Cécile Jacovetti, Clara Sanchez-Parra, Hélène Ezanno, Julien Bourry, Nicole Beeler, Gianni Pasquetti, Valery Gmyr, Stéphane Dalle, Julie Kerr-Conte, François Pattou, Syu-Ichi Hirai, Romano Regazzi, Amélie Bonnefond, Philippe Froguel, Amar Abderrahmani

Unveiling the key pathways underlying postnatal beta-cell proliferation can be instrumental to decipher the mechanisms of beta-cell mass plasticity to increased physiological demand of insulin during weight gain and pregnancy. Using transcriptome and global Serine Threonine Kinase activity (STK)…

Development of broadband high-frequency piezoelectric micromachined ultrasonic transducer array

Xu-Bo Wang, Le-Ming He, You-Cao Ma, Wen-Juan Liu, Wei-Jiang Xu, Jun-Yan Ren, Antoine Riaud, Jia Zhou

Piezoelectric micromachined ultrasonic transducers (PMUT) are promising elements to fabricate a two-dimensional (2D) array with a pitch small enough (approximately half wavelength) to form and receive arbitrary acoustic beams for medical imaging. However, PMUT arrays have so far failed to combine…

High-Q silicon nitride drum resonators strongly coupled to gates

Xin Zhou, Srisaran Venkatachalam, Ronghua Zhou, Hao Xu, Alok Pokharel, Andrew Fefferman, Mohammed Zaknoune, Eddy Collin

Silicon nitride (SiN) mechanical resonators with high quality mechanical properties are attractive for fundamental research and applications. However, it is challenging to maintain these mechanical properties while achieving strong coupling to an electrical circuit for efficient on-chip integration…

Optomechanic Coupling in Ag Polymer Nanocomposite Films

Adnane Noual, Eunsoo Kang, Tanmoy Maji, Manos Gkikas, Bahram Djafari-Rouhani, George Fytas

Particle vibrational spectroscopy has emerged as a new tool for the measurement of elasticity, glass transition, and interactions at a nanoscale. For colloid-based materials, however, the weakly localized particle resonances in a fluid or solid medium renders their detection difficult. The strong…

A comprehensive theoretical evaluation of the end-to-end performance of SoftCast-based linear video delivery schemes

Anthony Trioux, M Gharbi, François-Xavier Coudoux, Patrick Corlay

SoftCast-based linear video delivery (LVD) schemes have been proposed as an alternative to traditional video transmission schemes in wireless error-prone environments. The end-to-end performance of SoftCast-based schemes have been evaluated in Xiong et al. (2016), where a theoretical model based on…

CRC-Based Multi-Error Correction of H.265 Encoded Videos in Wireless Communications

Vivien Boussard, Stephane Coulombe, François-Xavier Coudoux, Patrick Corlay, Anthony Trioux

This paper analyzes the benefits of extending CRC-based error correction (CRC-EC) to handle more errors in the context of error-prone wireless networks. In the literature, CRC-EC has been used to correct up to 3 binary errors per packet. We first present a theoretical analysis of the CRC-EC…

UWB radar detection theory

Laila Sakkila, C. Tatkeu, Atika Rivenq, J. Zaidouni, Michael Bocquet

In this paper, a study of UWB receivers in terms of detection theory is presented. The UWB radar which is presented in many works previously [1]-[3] has many applications. For road UWB radar application, the receiver based on correlation is the optimum receiver [4]. In fact, it maximizes the…
