Spectrum Sensing Using Software Defined Radio for Cognitive Radio Networks: A Survey

Julio Manco-Vasquez, Iyad Dayoub, Amor Nafkha, Mohammad Alibakhshikenari, Hayfa Ben Thameur

Cognitive radio (CR) network has emerged as a potential solution to the under-utilization problem of the allocated radio spectrum, where spectrum sensing (SS) plays a key role to enable the coexistence between primary and secondary users. It has attracted research interests, and several works have...

Application of Complex Geophysical Methods for the Detection of Unconsolidated Zones in Flood Dikes

Tomisław Gołębiowski, Bogdan Piwakowski, Michał Ćwiklik

The flood levees in the vicinity of Krakow city (Poland) are, in some places, over 100 years old. Thereupon, in the flood dike, and its subsoil, can appear unconsolidated zones, which, during the flood stage, can be a simple way of water flow and/or even can be the place where the levee body will...

Metal nanoparticles decorated two-dimensional nanosheets as heterogeneous catalysts for coupling reactions

Manash Das, Najrul Hussain, Rituparna Duarah, Nidhi Sharma, Priyakhee Sarmah, Ashutosh Thakur, Prantika Bhattacharjee, Utpal Bora, Rabah Boukherroub

This review presents a brief discussion on the numerous synthetic techniques used to prepare metal nanoparticles supported on various two-dimensional (2D) materials. Special emphasis has been given to graphene and other 2D analogues such as g-C3N4, h-BN, MoS2, WS2 etc. supported metal nanoparticles...

The out-of-field dose in radiation therapy induces delayed tumorigenesis by senescence evasion

Erwan Goy, Maxime Tomezak, Caterina Facchin, Nathalie Martin, Emmanuel Bouchaert, Jerome Benoit, Clementine de Schutter, Joe Nassour, Laure Saas, Claire Drullion, Priscille Brodin, Alexandre Vandeputte, Olivier Molendi-Coste, Laurent Pineau, Gautier Goormachtigh, Olivier Pluquet, Albin Pourtier, Fabrizio Cleri, Eric Lartigau, Nicolas Penel, Corinne Abbadie

A rare but severe complication of curative-intent radiation therapy is the induction of second primary cancers. These cancers preferentially develop not inside the planning target volume (PTV) but around, over several centimeters, after a latency period of 1–40 years. We show here that normal human...

Wafer-level vapor cells filled with laser-actuated hermetic seals for integrated atomic devices

Vincent Maurice, Clément Carlé, Shervin Keshavarzi, Ravinder Kumar Chutani, Samuel Queste, Ludovic Gauthier-Manuel, Jean-Marc Cote, Rémy Vicarini, Moustafa Abdel Hafiz, Rodolphe Boudot, Nicolas Passilly

Atomic devices such as atomic clocks and optically-pumped magnetometers rely on the interrogation of atoms contained in a cell whose inner content has to meet high standards of purity and accuracy. Glass-blowing techniques and craftsmanship have evolved over many decades to achieve such standards...

A comparison of pad metallization in miniaturized microfabricated silicon microcantilever-based wafer probes for low contact force low skate on-wafer measurements

Khadim Daffe, Jaouad Marzouk, Christophe Boyaval, Gilles Dambrine, Kamel Haddadi, S. Arscott

Miniaturized, microfabricated microelectromechanical systems (MEMS)-based wafer probes are used here to evaluate different contact pad metallization at low tip forces (<mN) and low skate on the on-wafer pads. The target application is low force RF probes for on-wafer measurements which cause...

Decoding the neural signatures of valence and arousal from portable EEG headset

Nikhil Garg, Rohit Garg, Apoorv Anand, Veeky Baths

Emotion classification using electroencephalography (EEG) data and machine learning techniques have been on the rise in the recent past. However, past studies use data from medical-grade EEG setups with long set-up times and environment constraints. This paper focuses on classifying emotions on the...

Frequency response optimization of P-I-N photodiode based on InGaAsN lattice matched to GaAs for High-Speed photodetection applications

R. Amraoui, Abdelkader Aissat, Jean-Pierre Vilcot, Didier Decoster

This paper reports on pin photodiode frequency response optimization based on InxGa1-xAs1-yNy quaternary lattice matched to GaAs. Two transparent layers are placed on p-side and n-side in order to manage the photodiode frequency response limitations. The lattice matching condition is calculated in...

Face Sketch Synthesis using Generative Adversarial Networks

Mahfoud Sami, Daamouche Abdelhamid, Bengherabi Messaoud, Boutellaa Elhocine, Abdenour Hadid

Face Sketch Synthesis is crucial for a wide range of practical applications, including digital entertainment and law enforcement. Recent approaches based on Generative Adversarial Networks (GANs) have shown compelling results in image-to-image translation as well as face photo-sketch synthesis....

Redox-controlled conductance of polyoxometalate molecular junctions

Cécile Huez, David Guérin, Stéphane Lenfant, Florence Volatron, Michel Calame, Mickael Perrin, Anna Proust, Dominique Vuillaume

We demonstrate the reversible in situ photoreduction of molecular junctions of phosphomolybdate [PMo12O40]3- monolayer self-assembled on flat gold electrodes, connected by the tip of a conductive atomic force microscope. The conductance of the one electron reduced [PMo12O40]4- molecular junction is...
