Segmentation and classification of benign and malignant breast tumors via texture characterization from ultrasound images

Mohamed Benaouali, Mohamed Bentoumi, Menad Touati, Abdelmalik Taleb-Ahmed, Malika Mimi

The present paper deals with breast tumors classification from ultrasound images. The proposed procedure consists of four steps, namely preprocessing, segmentation, feature extraction and classification. To improve the quality of ultrasound images, the preprocessing step consists of anisotropic...

Adsorption-reduction of Cr(VI) onto unmodified and phytic acid-modified carob waste: Kinetic and isotherm modeling

Kenza Bouaouina, Alexandre Barras, Nacer Bezzi, Mohammed Amin, Sabine Szunerits, Rabah Boukherroub

Carob waste (CW) is an agro-biomass material abundant in nature with potential use for eco-friendly remediation. However, like many biomass-based adsorbents, it suffers from its low adsorption capacity for organic/inorganic pollutants. Therefore, modification using physical and/or chemical means is...

[Review] Lessons from neonatal β-cell epigenomic for diabetes prevention and treatment

Amar Abderrahmani, Cécile Jacovetti, Romano Regazzi

Pancreatic β-cell expansion and functional maturation during the birth-to-weaning period plays an essential role in the adaptation of plasma insulin levels to metabolic needs. These events are driven by epigenetic programs triggered by growth factors, hormones, and nutrients. These mechanisms...

Damage mechanisms assessment of Glass Fiber-Reinforced Polymer (GFRP) composites using multivariable analysis methods applied to acoustic emission data

W. Harizi, S. Chaki, G. Bourse, Mohamed Ourak

This work presents a coupling between three multivariable analysis techniques (Principal Component Analysis (PCA), K-means and Kohonen Self-Organizing Map (KSOM)) applied to the acoustic emission data recorded on Glass Fiber-Reinforced Polymer (GFRP) composite materials in order to monitor and...

Ionic Transport and Charge Distribution in Miniaturized Electrochemical Energy Storage Devices by Modeling Investigation

Yannick Dufil, Frederic Favier, Thierry Brousse, Christophe Lethien, Jean Le Bideau, Olivier Fontaine

Ions are at the core of the mechanism involved in electrochemical energy storage. However, it remains difficult to physically measure the local ionic transport inside a working device. Limiting factors in the local transport in miniaturized electrochemical energy storage (MEES), especially in 3D Li...

Influence of size and charge of carbon quantum dots on corneal penetration

Ines de Hoon, Alexandre Barras, Mike Wels, Bernd Vanmeerhaege, Stefaan de Smedt, Felix Sauvage, Sabine Szunerits

Purpose : Corneal blindness is the fourth leading cause of blindness. Currently, corneal transplantation is the only remaining therapeutic option as pharmacotherapy remains limited. As the cornea has several physiological and anatomical barriers, direct delivery of therapeutics into the eye remains...
