Defect-Mediated Nucleation and Dynamics across the Phase Transition in the Excitonic Insulator Candidate Ta2NiSe5
Guilherme Rodrigues-Fontenele, Gabriel Fontenele, Ângelo Malachias +1
Ta2NiSe5 is a quasi-one-dimensional material that exhibits a structural and electronic phase transition from a low-temperature monoclinic (semiconductor) to a high-temperature orth…
Experimental Kuramoto Platform
Leandro Freitas, Victor H. S. Bittencourt, Débora D. Superbi +3
Phase reduction provides a principled relationship between high-dimensional oscillator dynamics and low-dimensional phase models such as the Kuramoto model. However, connecting ana…
Pre-main Sequence B Stars Surrounding the Orion Nebula
P. H. F. B. Braz, A. Roman-Lopes, W. J. B. Corradi +6
Pre-main sequence (PMS) early-type stars are rare due to their rapid evolution. Confirming PMS B stars is accordingly valuable for constraining higher mass star formation scenarios…
SIMPLIFI -- Study of Interstellar Magnetic Polarization: a Legacy Investigation of Filaments. I. Magnetically-Guided Accretion onto the DR21 Ridge
Thushara G. S. Pillai, Jens Kauffmann, Juan D. Soler +15
We present first results from SIMPLIFI (Study of Interstellar Magnetic Polarization: a Legacy Investigation of Filaments), a SOFIA/HAWC+ polarimetric survey of Galact…
On Many-logic modal structures and information-based logics
Manuel Martins, Abílio Rodrigues, Marcelo Coniglio +1
This paper proposes an approach to information-based logics using many-logic modal structures (MLMS). These structures can express accessibility relations between worlds with diffe…
Large margin classifier with graph-based adaptive regularization
Vítor M. Hanriot, Turíbio T. Salis, Luiz C. B. Torres +2
This paper introduces the use of per-class regularization hyperparameters in Gabriel graph-based binary classifiers. We demonstrate how the quality index used for regularization be…
