Kavli Affiliate: Roberto Maiolino | First 5 Authors: Seunghwan Lim, Sandro Tacchella, Joop Schaye, Matthieu Schaller, Jakob M. Helton | Summary: Motivated by the recent JWST discovery of galaxy overdensities during the Epoch of Reionzation, we examine the physical properties of high-$z$ protoclusters and their evolution using the FLAMINGO simulation suite. We investigate the impact […]
Kavli Affiliate: Jing Wang | First 5 Authors: Panqi Jia, A. Burakhan Koyuncu, Jue Mao, Ze Cui, Yi Ma | Summary: The research on neural network (NN) based image compression has shown superior performance compared to classical compression frameworks. Unlike the hand-engineered transforms in the classical frameworks, NN-based models learn the non-linear transforms providing more […]
Kavli Affiliate: Ting Xu | First 5 Authors: Yanghao Su, Jie Zhang, Ting Xu, Tianwei Zhang, Weiming Zhang | Summary: Backdoor attacks pose a significant security vulnerability for deep neural networks (DNNs), enabling them to operate normally on clean inputs but manipulate predictions when specific trigger patterns occur. Currently, post-training backdoor detection approaches often operate […]
Kavli Affiliate: Ting Xu | First 5 Authors: Yanghao Su, Jie Zhang, Ting Xu, Tianwei Zhang, Weiming Zhang | Summary: Deep neural networks (DNNs) have revolutionized various industries, leading to the rise of Machine Learning as a Service (MLaaS). In this paradigm, well-trained models are typically deployed through APIs. However, DNNs are susceptible to backdoor […]
Kavli Affiliate: Xian Chen | First 5 Authors: Shun-Jia Huang, En-Kun Li, Jian-dong Zhang, Xian Chen, Zucheng Gao | Summary: The cosmic distance duality relation (CDDR), expressed as DL(z) = (1 + z)2DA(z), plays an important role in modern cosmology. In this paper, we propose a new method of testing CDDR using strongly lensed gravitational […]
Kavli Affiliate: Leon Balents | First 5 Authors: Léo Mangeolle, Lucile Savary, Leon Balents, , | Summary: We systematically derive the quantum kinetic equation in full phase space for any quadratic hamiltonian of bosonic fields, including in the absence of translational invariance. This enables the treatment of boundaries, inhomogeneous systems and states with non-trivial textures, […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Ahmed, H. Aihara | Summary: We present GFlaT, a new algorithm that uses a graph-neural-network to determine the flavor of neutral $B$ mesons produced in $Upsilon(4S)$ decays. It improves previous algorithms by using the information from all charged final-state […]

Kavli Affiliate: Yi Zhou | First 5 Authors: Liwen Tan, Yin Cao, Yi Zhou, , | Summary: Modality discrepancies have perpetually posed significant challenges within the realm of Automated Audio Captioning (AAC) and across all multi-modal domains. Facilitating models in comprehending text information plays a pivotal role in establishing a seamless connection between the two […]
Kavli Affiliate: Jia Liu | First 5 Authors: Haipeng An, Shuailiang Ge, Jia Liu, Zhiyao Lu, | Summary: In this study, we propose an investigation into dark photon dark matter (DPDM) within the infrared frequency band, utilizing highly sensitive infrared light detectors commonly integrated into space telescopes, such as the James Webb Space Telescope (JWST).
