Topological valley, pseudospin, and pseudospin-valley protected edge states in symmetric pillared phononic crystals

Wei Wang​, Bernard Bonello, Bahram Djafari-Rouhani, Yan Pennec

We present a symmetric double-sided pillared phononic crystal (PPnC) where either quantum spin Hall effect (QSHE) or quantum valley Hall effect (QVHE) is emulated by solely imposing different perturbations to the geometry. When occurring at the deep subwavelength scale, the valley-polarized edge...

Giant, Anomalous Piezoimpedance in Silicon-on-insulator

H. Li, C.T.K. Lew, B.C. Johnson, J.C. Mccallum, S. Arscott, A.C.H. Rowe

A giant, anomalous piezoresponse of fully depleted silicon-on-insulator devices under mechanical stress is demonstrated by impedance spectroscopy. This piezoresponse strongly depends on the measurement frequency, ω, and consists of both a piezoresistance (PZR) and a piezocapacitance, whose maximum...

Numerical Modelling of Vibration Characteristics of a Partially Metallized Micro Electromechanical System Resonator Disc

Ismail Naciri, Abdessamad Rguiti, Lahoucine Elmaimouni, Jean-Etienne Lefebvre, Faniry Emilson Ratolojanahary, J. G. Yu, Youssef Belkassmi, Ali El Moussati

In this paper, we report an extension of a polynomial and numerical vibrational characterization of an annular piezoelectric disc resonator partially covered with electrodes. The three governing partial differential equations of motion are solved to provide the frequency response of the...

Optimization of surface treatment on MEMS probes for single-cell capture and release

Kensaku Hayashi, Momoko Kumemura, Shohei Kaneda, Vivek Menon, Laurent Jalabert, Saeko Tachikawa, Mehmet Tarhan, Teruo Fujii, Beomjoon Kim, Hiroyuki Fujita

Micro-electromechanical systems (MEMS) tweezers developed for the trapping and characterization of bio molecules such as DNA are also capable of cell handling, which will enable further application involving single cell characterization. However, cellular adhesion to Si tweezers surfaces can...

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...

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...

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...

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...
