Kavli Affiliate: Jia Liu | First 5 Authors: Lifeng Chen, Jia Liu, Yan Ke, Wenquan Sun, Weina Dong | Summary: A watermarking algorithm is proposed in this paper to address the copyright protection issue of implicit 3D models. The algorithm involves embedding watermarks into the images in the training set through an embedding network, and […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Keisuke Inomata, Masahiro Kawasaki, Kyohei Mukaida, Tsutomu T. Yanagida, | Summary: The stochastic gravitational wave background (SGWB) recently detected by the PTA collaborations could be the gravitational waves (GWs) induced by curvature perturbations. However, primordial black holes (PBHs) might be overproduced if the SGWB is explained by […]
Kavli Affiliate: Jia Liu | First 5 Authors: Weina Dong, Jia Liu, Yan Ke, Lifeng Chen, Wenquan Sun | Summary: The utilization of implicit representation for visual data (such as images, videos, and 3D models) has recently gained significant attention in computer vision research. In this letter, we propose a novel model steganography scheme with […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: So Chigusa, Dan Kondo, Hitoshi Murayama, Risshin Okabe, Hiroyuki Sudo | Summary: We propose to use the nuclear spin excitation in the ferromagnetic A1 phase of the superfluid $^3$He for the axion dark matter detection. This approach is striking in that it is sensitive to the axion-nucleon […]
Kavli Affiliate: David N. Spergel | First 5 Authors: Oliver H. E. Philcox, Morgane J. König, Stephon Alexander, David N. Spergel, | Summary: The shapes of galaxies trace scalar physics in the late-Universe through the large-scale gravitational potential. Are they also sensitive to higher-spin physics? We present a general study into the observational consequences of […]
Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: We introduce and begin the study of quasi-BPS categories for K3 surfaces, which are a categorical version of the BPS cohomologies for K3 surfaces. We construct semiorthogonal decompositions of derived categories of coherent sheaves on moduli stacks of semistable […]
Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: In previous work, we studied quasi-BPS categories (of symmetric quivers with potential, of preprojective algebras, of surfaces) and showed they have properties analogous to those of BPS invariants/ cohomologies. For example, quasi-BPS categories are used to formulate categorical analogues […]
Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: We study certain categories associated to symmetric quivers with potential, called quasi-BPS categories. We construct semiorthogonal decompositions of the categories of matrix factorizations for moduli stacks of representations of (framed or unframed) symmetric quivers with potential, where the summands […]
Kavli Affiliate: Jia Liu | First 5 Authors: Moyan Li, Jinmiao Fu, Shaoyuan Xu, Huidong Liu, Jia Liu | Summary: On shopping websites, product images of low quality negatively affect customer experience. Although there are plenty of work in detecting images with different defects, few efforts have been dedicated to correct those defects at scale. […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Garv Chauhan, Shunsaku Horiuchi, Patrick Huber, Ian M. Shoemaker, | Summary: Sterile neutrinos can be produced through mixing with active neutrinos in the hot and dense core of a core-collapse supernova (SN). The standard bounds on the active-sterile mixing ($sin^2 theta$) from SN arise from SN1987A energy-loss, […]
