Dipole-independent measurements of nearly-zero CMB correlation: a possible symmetry of primordial causal quantum coherence

Posted by klaurent December 26, 2023Chicago

Kavli Affiliate: Stephan Meyer | Summary:Anisotropy of space-time is measured on the scale of the cosmic horizon, using the angular correlation function $C(Θ)$ of cosmic microwave background (CMB) temperature at large angular separation $Θ$. Even-parity correlation $C_rm even(Θ)$ is introduced to obtain a direct, precise measure of horizon-scale curvature anisotropy independent of the unknown dipole, […]

Causal bounds on cosmological angular correlation

Posted by December 26, 2023Chicago

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 […]

Dual-scale Enhanced and Cross-generative Consistency Learning for Semi-supervised Medical Image Segmentation

Posted by dbos December 26, 2023UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Yunqi Gu, Tao Zhou, Yizhe Zhang, Yi Zhou, Kelei He | Summary: Medical image segmentation plays a crucial role in computer-aided diagnosis. However, existing methods heavily rely on fully supervised training, which requires a large amount of labeled data with time-consuming pixel-wise annotations. Moreover, accurately segmenting lesions […]
