The design and study of structures exhibiting bound states in the continuum (BICs) are the object of continuous works in wave physics. These long-lived states which are localized in some parts of the system without interacting with the background have found several potential applications due to…

RGBD deep multi-scale network for background subtraction

Ihssane Houhou, Athmane Zitouni, Yassine Ruichek, Salah Eddine Bekhouche, Mohamed Kas, Abdelmalik Taleb-Ahmed

This paper proposes a novel deep learning model called deep multi-scale network (DMSN) for background subtraction. This convolutional neural network is built to use RGB color channels and Depth maps as inputs with which it can fuse semantic and spatial information. In comparison with previous deep…

Facial age estimation using tensor based subspace learning and deep random forests

O. Guehairia, F. Dornaika, A. Ouamane, Abdelmalik Taleb-Ahmed

Recently, the estimation of facial age has attracted much attention. This letter extends and improves a recently developed method (Guehairia et al., 2020) for fusing multiple deep facial features for age estimation. This method was based on deep random forests. We propose a new pipeline that…

Selective sublimation of GaN and regrowth of AlGaN to co-integrate enhancement mode and depletion mode high electron mobility transistors

Thi Huong Ngo, Rémi Comyn, Sébastien Chenot, Julien Brault, Maud Nemoz, Philippe Vennéguès, Benjamin Damilano, S. Vézian, Eric Frayssinet, Flavien Cozette, N. Defrance, François Lecourt, Nathalie Labat, Hassan Maher, Yvon Cordier

In the present study, the selective sublimation of the p-GaN cap layer of Al(Ga)N/GaN HEMTs is developed to replace the commonly used dry etching with no risk of damage in the barrier layer in order to fabricate enhanced mode transistors. Thanks to this approach, enhancement-mode transistors are…

Desorption timescales on epitaxial graphene via Fermi level shifting and Reststrahlen monitoring

Ngoc Thanh Mai Tran, Swapnil Mhatre, Cristiane Santos, Adam Biacchi, Mathew Kelley, Heather Hill, Dipanjan Saha, Chi-Te Liang, Randolph Elmquist, David Newell, Benoit Hackens, Christina Hacker, Albert Rigosi

This work reports information on the transience of hole doping in epitaxial graphene devices when nitric acid is used as an adsorbent. Under vacuum conditions, desorption processes are monitored by electrical and spectroscopic means to extract the relevant timescales from the corresponding data. It…

Improvement of emotion recognition from facial images using deep learning and early stopping cross validation

Mohamed Bentoumi, Mohamed Daoud, Mohamed Benaouali, Abdelmalik Taleb-Ahmed

Inthis paper, we present a new approach for emotion recognition from facial images. The proposed method is based on the association of a pretrained convolutional neural network (CNN) model (VGG16, ResNet50) with a multilayer perceptron (MLP) classifier. The pretrained CNN model is used as a feature…

Statistical mechanics of rate-independent stick-slip on a corrugated surface composed of parabolic wells

Stefano Giordano

The stick-slip phenomenon, at the basis of friction, is crucial for several applications ranging from nanotechnology and biophysics to mechanics and geology. Deep understanding of friction mechanisms and, in particular, the methodologies for its reduction must be sought in its nanoscopic nature,…
