Autor: Reina-Valero, José, Díaz-Morcillo, Alejandro, Gadea-Rodríguez, José, Gimeno, Benito, Lozano-Guerrero, Antonio José, Monzó-Cabrera, Juan, Navarro-Madrid, Jose R., Pedreño-Molina, Juan Luis

We present the first analysis of Dark Matter axion detection applying neural networks for the improvement of signal-to-noise ratio. The main sources of thermal noise from a typical read-out chain are simulated, constituted by resonant and amplifier n

The Zirconium (Z = 40) isotopic chain has attracted interest for more than four decades. The abrupt lowering of the energy of the first $2^+$ state and the increase in the transition strength B(E2; $2_1^\rightarrow 0_1^+$ going from $^{98}$Zr to $^{1

Learning diffusion at lightspeed

Autor: Terpin, Antonio, Lanzetti, Nicolas, Gadea, Martin, Dörfler, Florian

Diffusion regulates numerous natural processes and the dynamics of many successful generative models. Existing models to learn the diffusion terms from observational data rely on complex bilevel optimization problems and model only the drift of the s

Reading Order Independent Metrics for Information Extraction in Handwritten Documents

Autor: Villanova-Aparisi, David, Tarride, Solène, Martínez-Hinarejos, Carlos-D., Romero, Verónica, Kermorvant, Christopher, Pastor-Gadea, Moisés

Information Extraction processes in handwritten documents tend to rely on obtaining an automatic transcription and performing Named Entity Recognition (NER) over such transcription. For this reason, in publicly available datasets, the performance of
