Event-driven cardiac arrhythmia classification using antidictionaries, Classification d’arythmie cardiaque par antidictionaires en mode évènementiel

Julien Duforest

Cardiovascular diseases are the leading cause of death globally, represent-ing 31.4% of all deaths in the world in 2022. With more than half of all cardiovascu-lar disease-related deaths happening in settings outside of the hospital, there is a needfor constant at-home monitoring to prevent them.…, Les maladies cardiovasculaires sont la principale cause de mortalité dans le monde, représentant 31.4% des morts dans le monde en 2022. Avec plus de la moitié des morts liées aux maladies cardiovasculaires survenant en dehors de l'hôpital, il y a un besoin pour un système de surveillance à la…

Selective area epitaxy of in-plane HgTe nanostructures on CdTe(001) substrate

N Chaize, X Baudry, P-H Jouneau, E Gautier, J-L Rouvière, Y Deblock, J Xu, M Berthe, C Barbot, B Grandidier, L Desplanque, H Sellier, P Ballet

Semiconductor nanowires (NWs) are believed to play a crucial role for future applications in electronics, spintronics and quantum technologies. A potential candidate is HgTe but its sensitivity to nanofabrication processes restrain its development. A way to circumvent this obstacle is the selective…
