Band structure tuning at (La,Sr)MnO3 / (Ba,Sr)TiO3 interface

Jérôme Wolfman, Antoine Ruyter, B. Negulescu, Pascal Andreazza, Xavier Wallart, Sylvie Schamm-Chardon, Robin Cours, Teresa Hungria, Cecile Autret

Band structure engineering in silicon-based heterostructures dedicated to microelectronic and energy harvesting applications has been common material scientist playground for decades. Careful design of the energy level variation at hetero-interfaces is used e.g. to collect electron while preventing…

100 Gbit/s THz Data Transmission and Beyond using Multicore Fiber Combined with UTC Photodiode Array

Alfred Bewindin Sawadogo, Aritrio Bandyopadhyay, Malek Zegaoui, Mohammed Zaknoune, P. Szriftgiser, Karen Baudelle, Monika Bouet, Géraud Bouwmans, Davy Gaillot, Esben Ravn Andresen, Guillaume Ducournau, Laurent Bigot

Photonics-driven transmitters are leading the race towards high data-rates at THz frequencies. Here, spatial-multiplexing based on multicore fiber and photodiodes array is considered to alleviate the limited output power. Sub-systems have been developed and validated.

Parametric excitation of a gravity–capillary wave by radiation pressure of ultrasound

Leonid Krutyansky, Vladimir L. Preobrazhensky, Andrey Brysev, Philippe Pernod, R. Klopotov

Parametric instability of a standing gravity–capillary wave is observed in conditions of irradiation of a surface of a liquid by a plane ultrasound beam modulated by amplitude. A threshold value of ultrasound intensity for excitation of the parametric oscillations of the surface is determined, and…

Single cell classification using statistical learning on mechanical properties measured by mems tweezers

Bahram Ahmadian, Deborah Mbujamba, Jean Claude Gerbedoen, Momoko Kumemura, Hiroyuki Fujita, Dominique Collard, Sophie Dabo-Niang, Chann Lagadec, Mehmet Tarhan

Cell population is heterogenous and so presents a wide range of properties as metastatic potential. But using rare cells for clinical applications requires precise classification of individual cells. Here, we propose a multi-parameter analysis of single cells to classify them using statistical…

The good, the bad and the ugly polishing: Effect of abrasive size on standardless EDS analysis of Portland cement clinker’s calcium silicates

Vincent Thiéry, Emmanuel Dubois, Séverine Bellayer

Standardless Energy dispersive spectroscopy (EDS) on polished samples of Portland cement clinker is routinely performed both for unhydrated phases as well as in cement pastes. Typically, the calcium to silica ratio is investigated. EDS analyses are highly dependent on the polishing quality of the…

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…

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…

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…

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…
