Ultra-sensitive heterodyne detection at room temperature in the atmospheric windows
Mohammadreza Saemian, Livia Del Balzo, Djamal Gacemi +9
We report room temperature heterodyne detection of a quantum cascade laser beaten with a local oscillator on a unipolar quantum photodetector in two different atmospheric windows,…
Highly coherent phase-lock of an 8.1 m quantum cascade laser to a turn-key mid-IR frequency comb
B. Chomet, D. Gacemi, O. Lopez +5
A continuous-wave Fabry-Perot quantum cascade laser (QCL) emitting at 8.1 m operating in the single mode regime has been coherently phase locked to a turn-key low-noise commerci…
An indoor DSO-based ceiling-vision odometry system for indoor industrial environments
Abdelhak Bougouffa, Emmanuel Seignez, Samir Bouaziz +1
Autonomous Mobile Robots operating in indoor industrial environments require a localization system that is reliable and robust. While Visual Odometry (VO) can offer a reasonable es…
Unleashing the Transformative Power of Deliberation With Contextual Citizens
Ariane Lambert-Mogiliansky, Irénée Frérot
In this paper, we investigate deliberation procedures that invite citizens with contextual opinions to explore alternative thinking frames. Contextuality is captured in a simple qu…
Are Stellar Embryos in Perseus Radio-Synchrotron Emitters? Statistical data analysis with Herschel and LOFAR paving the way for the SKA
Andrea Bracco, Marco Padovani, Daniele Galli +3
Cosmic rays (CRs) are fundamental to the chemistry and physics of star-forming regions, influencing molecular gas ionization, mediating interactions with interstellar magnetic fiel…
Bow Metrics and Hyperbolicity
Feodor F. Dragan, Guillaume Ducoffe, Michel Habib +1
A ()-bow metric was defined in (Dragan & Ducoffe, 2023) as a far reaching generalization of an -metric (which is equivalent to a ()-bow metric). A graph is…
