Synthetic Over-sampling for Imbalanced Node Classification with Graph Neural Networks

Kavli Affiliate: Xiang Zhang | First 5 Authors: Tianxiang Zhao, Xiang Zhang, Suhang Wang, , | Summary: In recent years, graph neural networks (GNNs) have achieved state-of-the-art performance for node classification. However, most existing GNNs would suffer from the graph imbalance problem. In many real-world scenarios, node classes are imbalanced, with some majority classes making […]

Impact of late-time neutrino emission on the diffuse supernova neutrino background

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Nick Ekanger, Shunsaku Horiuchi, Kei Kotake, Kohsuke Sumiyoshi, | Summary: In the absence of high-statistics supernova neutrino measurements, estimates of the diffuse supernova neutrino background (DSNB) hinge on the precision of simulations of core-collapse supernovae. Understanding the cooling phase of protoneutron star (PNS) evolution ($gtrsim1,{rm s}$ after […]

Evolution of a Relativistic Outflow and X-ray Corona in the Extreme Changing-Look AGN 1ES 1927+654

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Megan Masterson, Erin Kara, Claudio Ricci, Javier A. García, Andrew C. Fabian | Summary: 1ES 1927+654 is a paradigm-defying AGN and one of the most peculiar X-ray nuclear transients. In early 2018, this well-known AGN underwent a changing-look event, in which broad optical emission lines appeared […]

A Fresh Look at AGN Spectral Energy Distribution Fitting with the XMM-SERVS AGN Sample

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Adam Marshall, Matthew W. Auger-Williams, Manda Banerji, Roberto Maiolino, Rebecca Bowler | Summary: We perform spectral energy distribution (SED) fitting to 711 luminous X-ray AGN at 0.7 < z < 4.5 using 10-bands of optical and infra-red photometric data for objects within XMM-SERVS. This fitting provided 510 […]

Spin Pumping into Anisotropic Dirac Electrons

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Takumi Funato, Takeo Kato, Mamoru Matsuo, , | Summary: We study spin pumping into an anisotropic Dirac electron system induced by microwave irradiation to an adjacent ferromagnetic insulator theoretically. We formulate the Gilbert damping enhancement due to the spin current flowing into the Dirac electron system using […]
