Understanding Server-Assisted Federated Learning in the Presence of Incomplete Client Participation

Kavli Affiliate: Jia Liu | First 5 Authors: Haibo Yang, Peiwen Qiu, Prashant Khanduri, Minghong Fang, Jia Liu | Summary: Existing works in federated learning (FL) often assume an ideal system with either full client or uniformly distributed client participation. However, in practice, it has been observed that some clients may never participate in FL […]

Semi-supervised Symmetric Matrix Factorization with Low-Rank Tensor Representation

Kavli Affiliate: Ran Wang | First 5 Authors: Yuheng Jia, Jia-Nan Li, Wenhui Wu, Ran Wang, | Summary: Semi-supervised symmetric non-negative matrix factorization (SNMF) utilizes the available supervisory information (usually in the form of pairwise constraints) to improve the clustering ability of SNMF. The previous methods introduce the pairwise constraints from the local perspective, i.e., […]

Merging gas-rich galaxies that harbor low-luminosity twin quasars at z = 6.05: a promising progenitor of the most luminous quasars

Kavli Affiliate: John D. Silverman | First 5 Authors: Takuma Izumi, Yoshiki Matsuoka, Masafusa Onoue, Michael A. Strauss, Hideki Umehata | Summary: We present ALMA [CII] 158 $mu$m line and underlying far-infrared continuum emission observations ($0”.57 times 0”.46$ resolution) toward a quasar-quasar pair system recently discovered at $z = 6.05$ (Matsuoka et al. 2024). The […]

Exomoons & Exorings with the Habitable Worlds Observatory I: On the Detection of Earth-Moon Analog Shadows & Eclipses

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Mary Anne Limbach, Jacob Lustig-Yaeger, Andrew Vanderburg, Johanna M. Vos, Rene Heller | Summary: The highest priority recommendation of the Astro2020 Decadal Survey for space-based astronomy was the construction of an observatory capable of characterizing habitable worlds. In this paper series we explore the detectability of and […]

X-ray Winds In Nearby-to-distant Galaxies (X-WING) – I: Legacy Surveys of Galaxies with Ultrafast Outflows and Warm Absorbers in $z sim 0$-$4$

Kavli Affiliate: Claudio Ricci | First 5 Authors: Satoshi Yamada, Taiki Kawamuro, Misaki Mizumoto, Claudio Ricci, Shoji Ogawa | Summary: As an inaugural investigation under the X-ray Winds In Nearby-to-distant Galaxies (X-WING) program, we assembled a dataset comprising 132 active galactic nuclei (AGNs) spanning redshifts $z sim 0$-$4$ characterized by blueshifted absorption lines indicative of […]

Gravothermal Catastrophe in Resonant Self-interacting Dark Matter Models

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Vinh Tran, Daniel Gilman, Mark Vogelsberger, Xuejian Shen, Stephanie O’Neil | Summary: We investigate a self-interacting dark matter (SIDM) model featuring a velocity-dependent cross section with an order-of-magnitude resonant enhancement of the cross section at $sim 16,{rm km},{rm s}^{-1}$. To understand the implications for the structure of […]
