In this article, we investigate optically induced terahertz radiation in ferromagnetic FeCo layers of varying thickness on Si and SiO2 substrates. Efforts have been made to account for the influence of the substrate on the parameters of the THz radiation generated by the ferromagnetic FeCo film....

Study of the economic impact of cryptosporidiosis in calves after implementing good practices to manage the disease on dairy farms in Belgium, France, and the Netherlands

Maud Roblin, Evi Canniere, Anne Barbier, Yvonne Daandels, Martine Dellevoet-Groenewegen, Pedro Pinto, Anastasios Tsaousis, Hélène Leruste, Julii Brainard, Paul Hunter, Jérôme Follet

Cryptosporidium spp. are widespread parasitic protozoans causing enteric infections in humans and animals. The parasites cause neonatal diarrhoea in calves, leading to a high mortality rate in the first three weeks. Losses are significant for farmers, but the cost of cryptosporidiosis remains...

Silicon Compatible Process To Integrate Impedance Cytometry With Mechanical Characterization

Quentin Rezard, Faruk Azam Shaik, Jean Claude Gerbedoen, Fabrizio Cleri, Dominique Collard, Chann Lagadec, Mehmet Tarhan

We introduced 3D silicon electrodes to perform impedance cytometry on single cells without compromising practical integration with sensors measuring complementary properties, e.g., mechanical properties. Microfabricated from a highly-doped SOI wafer, some design modifications were made to improve...

Frequency stable and low phase noise THz synthesis for precision spectroscopy

Léo Djevahirdjian, Loïc Lechevallier, Marie-Aline Martin-Drumel, Olivier Pirali, Guillaume Ducournau, Rédha Kassi, Samir Kassi

We present a robust approach to generate a continuously tunable, low phase noise, Hz linewidth and mHz/s stability THz emission in the 0.1 THz to 1.4 THz range. This is achieved by photomixing two commercial telecom, distributed feedback lasers locked by optical-feedback onto a single highly stable...

A fuzzy/possibility approach for area coverage in wireless sensor networks

Adda Boualem, Cyril de Runz, Marwane Ayaida, Herman Akdag

The literature approaches, devoted to sensor improve network coverage, are deterministic in terms of deployment environment and node configuration parameters. Nevertheless, this type of approaches has not proven to be very successful in uncertain deployment environments. This paper aims to deal...

Ultrafast Modulation of Polarization in Spintronic THz Emitters Enhanced by Field Induced Spin Reorientation Transition

Geoffrey Lezier, Pierre Koleják, Jean-Francois Lampin, Kamil Postava, Mathias Vanwolleghem, Nicolas Tiercelin

We demonstrate an efficient and simple modulation of the polarization in Spin-tronic Terahertz Emitters, by rapid switching of the magnetization using high-frequency magnetic field, enhanced by field induced Spin Reorientation Transition (SRT). The instability of the magnetic layer at the...

Progress in process development of La0.7Sr0.3MnO3 thin films for uncooled THz bolometers

Thomas Quinten, Yoann Lechaux, Victor Pierron, Chantal Gunther, Laurence Méchin, Jean-Francois Lampin, Marc Faucher, Benjamin Walter, Bruno Guillet

We present preliminary results of uncooled THz bolometers based on La 0.7 Sr 0.3 MnO 3 thin films on SrTiO3 buffered high resistivity silicon substrates. Fabrication improvements enable to obtain low contact resistance and the impedance measurements show that it is possible to minimize the...

Nanomechanical damping via electron-assisted relaxation of two-level systems

Olivier Maillet, Dylan Cattiaux, Xin Zhou, Rasul R. Gazizulin, Olivier Bourgeois, Andrew D. Fefferman, Eddy Collin

We report on measurements of dissipation and frequency noise at millikelvin temperatures of nanomechanical devices covered with aluminum. A clear excess damping is observed after switching the metallic layer from superconducting to the normal state with a magnetic field. Beyond the standard model...
