On The Performance Of Beamforming Techniques Based On 3D Predefined Codebook Designs In 3GPP Mobile Communication Systems

Semah Mabrouki, Iyad Dayoub, Marion Berbineau

The next decade will encounter many emerging applications that require the connection of new devices and the exchange of higher data rates. The mm Wave bands are considered as a solution that gives new facilities with a tremendous amount of spectrum to the fifth generation and beyond communications…

Ultrahigh vacuum Raman spectroscopy for the preparation of III–V semiconductor surfaces

Wijden Khelifi, Damien Canneson, Maxime Berthe, Sébastien Legendre, Christophe Coinon, Ludovic Desplanque, Xavier Wallart, Louis Biadala, Bruno Grandidier, Pierre Capiod

Raman spectroscopy is well-suited for the characterization of semiconductor materials. However, due the weakness of the Raman signal, the studies of thin semiconductor layers in complex environments, such as ultrahigh vacuum, are rather scarce. Here, we have designed a Raman apparatus based on the…

Strain topological metamaterials and revealing hidden topology in higher-order coordinates

Florian Allein, Adamantios Anastasiadis, Rajesh Chaunsali, Ian Frankel, Nicholas Boechler, Fotios Diakonos, Georgios Theocharis

Abstract Topological physics has revolutionized materials science, introducing topological phases of matter in diverse settings ranging from quantum to photonic and phononic systems. Herein, we present a family of topological systems, which we term “strain topological metamaterials”, whose…

Generation of β-like cell subtypes from differentiated human induced pluripotent stem cells in 3D spheroids

Lisa Morisseau, Fumiya Tokito, Stéphane Poulain, Valérie Plaisance, Valerie Pawlowski, Soo Hyeon Kim, Cecile Legallais, Rachid Jellali, Yasuyuki Sakai, Amar Abderrahmani, Eric Leclerc

Since the identification of four different pancreatic β-cell subtypes and bi-hormomal cells playing a role in the diabetes pathogenesis, the search for in vitro models that mimics such cells heterogeneity became a key priority in experimental and clinical diabetology. We investigated the potential…

On the One‐Dimensional Transition State Theory and the Relation between Statistical and Deterministic Oscillation Frequencies of Anharmonic Energy Wells

Stefano Giordano, Fabrizio Cleri, Ralf Blossey

The transition state theory allows the development of approximated models useful to study the non‐equilibrium evolution of systems undergoing transformations between two states (e.g., chemical reactions). In a simplified 1D setting, the characteristic rate constants are typically written in terms…

Robust backbone network based on hybrid selection of relays for multi-hop data dissemination in VANETs

Abdelmonom Hajjej, Marwane Ayaida, Sameh Najeh, Nadhir Messai, Leila Najjar

Relay nodes selection as a key word to ensure efficient multi-hop data dissemination in VANETs has received tremendous attention for many years. However, previous literature often fails to address two critical topics. Firstly, the conception of a reliable relay distribution model to ensure…

Magnetostrictive strain monitoring in Non-Oriented Si-Fe steels using a SAW resonator sensor

Othmane Marbouh, A. Mazzamurro, O. Bou Matar, Y. Dusch, W. Bekir, D. Laloy, K. Ettihir, A. Tounzi, A. Benabou, Abdelkrim Talbi

The aim of this study is to introduce a new technique for characterizing the magnetostrictive behavior of non-oriented ferromagnetic steel sheets using miniaturized wireless surface acoustic wave sensors (SAW). Unlike conventional optical and electromechanical techniques, this type of sensor offers…

Emergence and highly directed output of long-lived resonances in photonic step ladder structure

Leonard Dobrzynski, Housni Al-Wahsh, Abdellatif Akjouj, Eman Abdel-Ghaffar

A bound state eigenfunction is defined here to be strictly localized within a subspace of a system and has no decreasing behavior. Its eigenvalue can be within state continua. Bound states in the continuum (BICs) and long-lived resonances have become a unique way to produce the extreme localization…
