New adaptive filters as perceptual preprocessing for rate-quality performance optimization of video coding

Eloïse Vidal, Nicolas Sturmel, Christine Guillemot, Patrick Corlay, François-Xavier Coudoux

In this paper, we introduce two perceptual filters as pre-processing techniques to reduce the bitrate of compressed high-definition (HD) video sequences at constant visual quality. The goal of these perceptual filters is to remove spurious noise and insignificant details from the original video...

Three-dimensional (3D) culture of adult murine colon as an in vitro model of cryptosporidiosis: Proof of concept

Martha Baydoun, Sadia Benamrouz Vanneste, Colette Creusy, Karine Guyot, Nausicaa Gantois, Magali Chabe, Baptiste Delaire, Anthony Mouray, Atallah Baydoun, Gerard Forzy, Vincent Chieux, Pierre Gosset, Vincent Senez, Eric Viscogliosi, Jérôme Follet, Gabriela Certad

Cryptosporidium parvum is a major cause of diarrheal illness and was recently potentially associated with digestive carcinogenesis. Despite its impact on human health, Cryptosporidium pathogenesis remains poorly known, mainly due to the lack of a long-term culture method for this parasite. Thus,...

TUNING NEGATIVE DIFFERENTIAL RESISTANCE IN A SINGLE MOLECULE TRANSISTOR: DESIGNS OF LOGIC GATES AND EFFECTS OF VARIOUS OXYGEN-AND HYDROGEN-INDUCED DEFECTS

A Nasri, A Boubaker, B Hafsi, W Khaldi, A Kalboussi

In this paper, a theoretical study of Single Molecule Transistor (SMT) operating as a molecular field effect transistor (MFET) has been presented. We have applied the density functional theory (DFT) in conjugation with the non-equilibrium green's function (NEGF) formalism on a pentacene device...

Characterization of peptide attachment on silicon nanowires by X-ray photoelectron spectroscopy and mass spectrometry

Ievgen Kurylo, Mathieu Dupré, Sonia Cantel, Christine Enjalbal, Hervé Drobecq, Sabine Szunerits, Oleg Melnyk, Rabah Boukherroub, Yannick Coffinier

In this paper, we report an original method to immobilize a model peptide on silicon nanowires (SiNWs) via a photolinker attached to the SiNWs’ surface. The silicon nanowires were fabricated by a metal assisted chemical etching (MACE) method. Then, direct characterization of the peptide...

Finite element modeling of a piezoelectric slender bar transducer equipped with a multilayer backing for medical imaging applications

Nadia El Atlas, Abdelmajid Bybi, Hilal Drissi, Anne-Christine Hladky

The goal of this work is to investigate the impact of front and back matching layers properties on a piezoelectric slender bar transducer performances and to propose a novel multilayer backing absorber. Quarter-wavelength acoustic matching layers and backing are known as essential components to...

Modeling and optimization of core/shell p-i-n Si/Si0.2Ge0.8 nanowire for photovoltaic

Fethi Benyettou, Abdelkader Aissat, Isabelle Berbezier, Jean-Pierre Vilcot

In this work we propose a modeling and simulation of core/shell p-i-n Si/Si0.2Ge0.8 nanowire for photovoltaic. In the first step of this work, we have compared the core/shell p-i-n homo-junction Si and heterojunction Si/Si0.2Ge0.8 Nanowire (NW) solar cell having a length of 3 mu m and a radius of 0...
