neutron stars: from the 'normal' rotation-powered pulsars, to magnetars, the
most... |

English: Current graph neural networks (GNNs) that tackle node classification on
graphs tend to only focus on nodewise scores and are solely evaluated by
nodewise metrics. This limits uncertainty estimation on graphs since nodewise
marginals do not fully characterize the joint distribution given the graph
structure. ... |

1996. Am... |
English: Adversarial examples pose a significant challenge to deep neural networks
(DNNs) across both image and text domains, with the intent to degrade model

reported C2/c.... |
English: We consider an altermagnet subject to the electron attractive potential
mediated by the dispersive phonons. While altermagnetism suppresses
superconductivity, scattering of electrons on the Fermi surface by thermal
phonons suppresses altermagnetism. We show that this leads to the re-entrant
superconductivity... |
