Friedrich-Wintgen bound states in the continuum and induced resonances in a loop laterally coupled to a waveguide

Madiha Amrani, Soufyane Khattou, El Houssaine El Boudouti, Abdelkrim Talbi, Abdellatif Akjouj, Leonard Dobrzynski, Bahram Djafari-Rouhani

The concept of bound states in the continuum (BICs) in a simple cavity attracts much interest in recent works in wave physics. The BICs are perfectly confined modes with an infinite lifetime that reside inside the continuous spectrum of radiative modes, but they remain totally decoupled from it....

Solid-state 3D micro-supercapacitors based on ionogel electrolyte: Influence of adding lithium and sodium salts to the ionic liquid

Thibaud Guillemin, Camille Douard, Kévin Robert, Bouchra Asbani, Christophe Lethien, Thierry Brousse, Jean Le Bideau

The ever-increasing interest in miniaturized Internet of Things devices and embedded electronics has given rise to a host of inquiries surrounding the need for safe, high performance energy storage devices. Solid-state 3D micro-supercapacitors based on ionogels provide a promising response to many...

Sustainability in (bio-)analytical chemistry [Editorial]

Antje Baeumner, Günter Gauglitz, Luigi Mondello, María Cruz Moreno Bondi, Sabine Szunerits, Qiuquan Wang, Stephen Wise, Adam Woolley

We all live on this amazing planet, which, with available sunlight and abundant resources, offers more than enough to maintain life and livelihood. Nevertheless, how we continue to consume what the Earth provides will decide for what duration humanity will still be able to meet these ongoing needs...

Bound states in the continuum and Fano resonances in photonic and plasmonic loop structures

Madiha Amrani, Soufyane Khattou, Housni Al-Wahsh, Yamina Rezzouk, El Houssaine El Boudouti, Cécile Ghouila-Houri, Abdelkrim Talbi, Abdellatif Akjouj, L. Dobrzynski, Bahram Djafari-Rouhani

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...

Distinguishing cellular from abiotic spheroidal microstructures in the ca. 3.4 Ga Strelley Pool Formation

Maxime Coutant, Kevin Lepot, Alexandre Fadel, Ahmed Addad, Élodie Richard, David Troadec, Sandra Ventalon, Kenichiro Sugitani, Emmanuelle Javaux

The morphogenesis of most carbonaceous microstructures that resemble microfossils in Archean (4–2.5 Ga old) rocks remains debated. The associated carbonaceous matter may even—in some cases—derive from abiotic organic molecules. Mineral growths associated with organic matter migration may mimic...

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...

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...

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...

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...
