Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Ohkyung Kwon, Stephan S. Meyer, Nathaniel Selub, Frederick Wehlen | Summary: We formulate a new hypothesis for causal coherence of gravitational quantum fluctuations, and test its predicted constraints on large-scale angular correlations in the cosmic microwave background (CMB). We posit that {it quantum fluctuations generate […]
Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Ohkyung Kwon, Stephan S. Meyer, Nathaniel Selub, Frederick Wehlen | Summary: We test the hypothesis that angular correlations of gravitationally-induced temperature anisotropy in the cosmic microwave background (CMB) vanish over a range of large angular separations constrained by causality. Standard conformal geometry is used to […]

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Ohkyung Kwon, Stephan S. Meyer, Nathaniel Selub, Frederick Wehlen | Summary: The global isotropy of the universe is analyzed on the scale of the cosmic horizon, using the angular correlation function $C(Theta)$ of cosmic microwave background (CMB) temperature at large angular separation $Theta$. Even-parity correlation […]

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Jinagyun Li, Chen Chen, Yisi Zhang, Haoran Shen | Summary: The Few-Shot Segmentation (FSS) aims to accomplish the novel class segmentation task with a few annotated images. Current FSS research based on meta-learning focus on designing a complex interaction mechanism between the query and support […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Akifumi Chitose, Masahiro Ibe, Yuhei Nakayama, Satoshi Shirai, Keiichi Watanabe | Summary: Metastable cosmic strings appear in models of new physics with a two-step symmetry breaking $Gto Hto 1$, where $pi_1(H)neq 0$ and $pi_1(G)=0$. They decay via the monopole-antimonopole pair creation inside. Conventionally, the breaking rate has […]

Kavli Affiliate: Jia Liu | First 5 Authors: Tian Xia, Jia Liu, Zhiping Chen, , | Summary: In this paper, we study the distributionally robust joint chance constrained Markov decision process. {Utilizing the logarithmic transformation technique,} we derive its deterministic reformulation with bi-convex terms under the moment-based uncertainty set. To cope with the non-convexity and […]
