Chapter 2 - Magnonic circuits: comb structures

Abdellatif Akjouj, Housni Al-Wahsh, L. Dobrzynski, Bahram Djafari-Rouhani, El Houssaine El Boudouti

In the frame of long-wavelength Heisenberg model, a simple magnonic mono-mode circuit is designed to obtain transmission stop (pass) bands where the propagation of spin waves is forbidden (allowed). This simple device is composed of an infinite one-dimensional mono-mode waveguide along which side...

Optimal power allocation in a relay-aided cognitive network

Anne Savard, E. Veronica Belmega

In this paper, we address a power allocation problem in a relay-aided cognitive network. The network is composed by a primary and secondary user/ destination pair and a relay, which helps the communication between the secondary user and its destination. The transmission of the secondary user and...

Highly confined radial contour modes in phononic crystal plate based on pillars with cap layers

Mohammed Moutaouekkil, Abdelkrim Talbi, El Houssaine El Boudouti, Omar Elmazria, Bahram Djafari-Rouhani, Philippe Pernod, Olivier Bou Matar

We investigate highly confined and isolated surface modes in a phononic crystal plate based on pillars with cap layers. The structure is made of a thin membrane supporting periodic pillars each composed of one cylinder surmounted by a disk shaped cap layer. An optimal choice of the geometrical...

Near-infrared light activatable hydrogels for metformin delivery

Li Chengnan, Quentin Pagneux, Anna Voronova, Alexandre Barras, Amar Abderrahmani, Valérie Plaisance, Valérie Pawlowski, Nathalie Hennuyer, Bart Staels, Lea Rosselle, Nadia Skandrani, Musen Li, Rabah Boukherroub, Sabine Szunerits

Drug loaded hydrogels have proven to be versatile controlled-release systems. We report here on heat active hydrogel formation by mixing graphene oxide (GO) or carboxyl enriched reduced graphene oxide (rGO-COOH) with metformin hydrochloride, an insulin sensitizer drug currently used as the first...

Medical video coding based on 2nd-generation wavelets: performance evaluation

Merzak Ferroukhi, Abdeldjalil Ouahabi, Mokhtar Attari, Yassine Habchi, Abdelmalik Taleb-Ahmed

The operations of digitization, transmission and storage of medical data, particularly images, require increasingly effective encoding methods not only in terms of compression ratio and flow of information but also in terms of visual quality. At first, there was DCT (discrete cosine transform) then...

Blocking bacterial entry at the adhesion step reveals dynamic recruitment of membrane and cytosolic probes

Yann Ciczora, Sébastien Janel, Magali Soyer, Michka Popoff, Elisabeth Werkmeister, Frank Lafont

Background: Bacterial invasion covers two steps: adhesion and entry per se. The cell signalling response is triggered upon pathogen interaction at the cell surface. This response continues when the pathogen is internalised. It is likely that these two steps activate different molecular machineries...

Elastic wave propagation in smooth and wrinkled stratified polymer films

M Hesami, A. Gueddida, N Gomopoulos, H S Dehsari, K Asadi, S Rudykh, H-J Butt, Bahram Djafari-Rouhani, G Fytas

Periodic materials with sub-micrometer characteristic length scale can provide means for control of propagation of hypersonic phonons. In addition to propagation stopbands for the acoustic phonons, distinct dispersive modes can reveal specific thermal and mechanical behavior under confinement. Here...
