Kavli Affiliate: Wei Gao | First 5 Authors: Chunyang Fu, Ge Li, Rui Song, Wei Gao, Shan Liu | Summary: In point cloud compression, sufficient contexts are significant for modeling the point cloud distribution. However, the contexts gathered by the previous voxel-based methods decrease when handling sparse point clouds. To address this problem, we propose […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Zhenhai Yu1, Xuejiao Chen, Wei Xia, Ningning Wang, Xiaodong Lv | Summary: The rich nontrivial topological phases rooted in the interplay between magnetism and topology in the layered antiferromagnet EuCd2As2 have captured vast attention, especially the ideal Weyl semimetal state realized in the spin-polarized ferromagnetic (FM) […]
Kavli Affiliate: Wei Gao | First 5 Authors: Xianghao Zang, Ge Li, Wei Gao, , | Summary: In video surveillance, pedestrian retrieval (also called person re-identification) is a critical task. This task aims to retrieve the pedestrian of interest from non-overlapping cameras. Recently, transformer-based models have achieved significant progress for this task. However, these models […]
Kavli Affiliate: W. L. Kimmy Wu | First 5 Authors: Dominic Beck, Ari Cukierman, W. L. Kimmy Wu, , | Summary: We investigate simulation-based bandpower covariance matrices commonly used in cosmological parameter inferences such as the estimation of the tensor-to-scalar ratio $r$. We find that upper limits on $r$ can be biased low by tens […]

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Robert T. Zellem, Bijan Nemati, Vanessa P. Bailey, Eric J. Cady, M. Mark Colavita | Summary: NASA’s next flagship mission, the Nancy Grace Roman Space Telescope, is a 2.4-meter observatory set to launch no later than May 2027. Roman features two instruments: the Wide Field Imager and […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Shuai A. Chen, Qianqian Chen, Zheng Zhu, , | Summary: Recent realization of well-controlled quantum simulators of the triangular-lattice Fermi-Hubbard model, including the triangular optical lattices loaded with ultracold Fermions and the heterostructures of the transition-metal dichalcogenides, as well as the more advanced techniques to probe them, […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Justin M. Wittrock, Stefan Dreizler, Michael A. Reefe, Brett M. Morris, Peter P. Plavchan | Summary: We explore the transit timing variations (TTVs) of the young (22 Myr) nearby AU Mic planetary system. For AU Mic b, we introduce three Spitzer (4.5 $mu$m) transits, five TESS transits, […]

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Veselin B. Kostov, Brian P. Powell, Saul A. Rappaport, Tamas Borkovits, Robert Gagliano | Summary: We present a catalog of 97 uniformly-vetted candidates for quadruple star systems. The candidates were identified in TESS Full Frame Image data from Sectors 1 through 42 through a combination of machine […]
