Alexander V Korovin, Yan Pennec, Matteo Stocchi, Davide Mencarelli, Luca Pierantoni, Tapani Makkonen, Jouni Ahopelto, Bahram Djafari-Rouhani

The generation of acoustic waves in structured nanobeams containing optomechanic cavities is a topic of current interest. In this paper, we theoretically study the efficient conversion of surface acoustic waves (SAW) generated on a substrate by an RF electric signal into the acoustic waves of a...

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...

Massless Dirac fermions in III-V semiconductor quantum wells

Sergey S. Krishtopenko, W. Desrat, K. Spirin, C. Consejo, S. Ruffenach, F. Gonzalez-Posada, Benoit Jouault, W. Knap, K. Maremyanin, V. Gavrilenko, G. Boissier, J. Torres, M. Zaknoune, E. Tournié, F. Teppe

We report on the clear evidence of massless Dirac fermions in two-dimensional system based on III-V semiconductors. Using a gated Hall bar made on a three-layer InAs/GaSb/InAs quantum well, we restore the Landau level fan chart by magnetotransport and unequivocally demonstrate a gapless state in...

Design of a four-branch optical power splitter based on gallium-nitride using rectangular waveguide coupling for telecommunication links

Retno Wigajatri Purnamaningsih, Nji Raden Poespawati, El Hadj Dogheche

This paper reports design of a simple four-branch optical power splitter using five parallel rectangular waveguides coupling in a gallium-nitride (GaN) semiconductor/sapphire for telecommunication links. The optimisation was conducted using the 3D FD-BPM method for long wavelength optical...

Ferroelectric multiple-valued logic units

Igor A. Luk'Yanchuk, Elena Zaitseva, Vitaly Levashenko, Miroslav Kvassay, Svitlana Kondovych, Yuri Tikhonov, Laurent Baudry, Anna Razumnaya

Employing many-valued logic (MVL) data processing allows to dramatically increase the performance of computing circuits. Here we propose to employ ferroelectrics for the material implementation of MVL units basing on their ability to pin the polarization as a sequence of multi-stable states. Two...

Exploring Light-Sensitive Nanocarriers for Simultaneous Triggered Antibiotic Release and Disruption of Biofilms Upon Generation of Laser-Induced Vapor Nanobubbles

Impaired penetration of antibiotics through bacterial biofilms is one of the reasons for failure of antimicrobial therapy. Hindered drug diffusion is caused on the one hand by interactions with the sticky biofilm matrix and on the other hand by the fact that bacterial cells are organized in densely...

Evaluation of the hydrophobic properties of latex microspheres and <em>Bacillus</em> spores. Influence of the particle size on the data obtained by the MATH method (microbial adhesion to hydrocarbons)

Christine Faille, Christelle Lemy, Audrey Allion-Maurer, Farzam Zoueshtiagh

The current experimental study investigates the influence of latex microsphere particles' size on the assessment of their hydrophilic/hydrophobic character, using the method known as “Microbial Adhesion to Hydrocarbons” (MATH). Since bacteria surfaces often change according to the environment...
