The THESAN project: connecting ionized bubble sizes to their local environments during the Epoch of Reionization

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Meredith Neyer, Aaron Smith, Rahul Kannan, Mark Vogelsberger, Enrico Garaldi | Summary: An important characteristic of cosmic reionization is the growth of ionized gas bubbles surrounding early luminous objects. Understanding the connections between the formation and coalescence of these bubbles and their originating astrophysical sources is equally […]

Certifiably Robust Graph Contrastive Learning

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Minhua Lin, Teng Xiao, Enyan Dai, Xiang Zhang, Suhang Wang | Summary: Graph Contrastive Learning (GCL) has emerged as a popular unsupervised graph representation learning method. However, it has been shown that GCL is vulnerable to adversarial attacks on both the graph structure and node attributes. Although […]

Dual Prompt Tuning for Domain-Aware Federated Learning

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Guoyizhe Wei, Feng Wang, Anshul Shah, Rama Chellappa, | Summary: Federated learning is a distributed machine learning paradigm that allows multiple clients to collaboratively train a shared model with their local data. Nonetheless, conventional federated learning algorithms often struggle to generalize well due to the ubiquitous domain […]

A surprisingly high number of dual active galactic nuclei in the early Universe

Posted by klaurent Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Michele Perna, Santiago Arribas, Isabella Lamperti, Chiara Circosta, Elena Bertola | Summary: Merger events can trigger gas accretion onto supermassive black holes (SMBHs) sitting at the centre of galaxies, and form close pairs of active galactic nuclei (AGN). The fraction of AGN in pairs gives key information […]

A Neural Scaling Law from Lottery Ticket Ensembling

Posted by klaurent MIT

Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Max Tegmark, , , | Summary: Neural scaling laws (NSL) refer to the phenomenon where model performance improves with scale. Sharma & Kaplan analyzed NSL using approximation theory and predict that MSE losses decay as $N^{-alpha}$, $alpha=4/d$, where $N$ is the number of model parameters, […]

Integrability of Large-Charge Sectors in Generic 2D EFTs

Posted by klaurent Tokyo

Kavli Affiliate: Simeon Hellerman | First 5 Authors: Matthew Dodelson, Simeon Hellerman, Masataka Watanabe, Masahito Yamazaki, | Summary: It is shown that integrability is an accidental property of generic two-dimensional $O(2)$-symmetric asymptotically-free theories in the regime where the charge density is much larger than the dynamical scale. We show this by constructing an infinite tower […]

MAP1B Regulates Cortical Neuron Interstitial Axon Branching Through the Tubulin Tyrosination Cycle

Posted by klaurent Hopkins

Kavli Affiliate: Alex Kolodkin | Authors: Jakub Ziak, Joelle Dorskind, Brian Trigg, Sriram Sudarsanam, Randal Hand and Alex L Kolodkin | Summary: Regulation of directed axon guidance and branching during development is essential for the generation of neuronal networks. However, the molecular mechanisms that underlie interstitial axon branching in the mammalian brain remain unresolved. Here, […]

X-ray Polarization of the BL Lac Type Blazar 1ES 0229+200

Posted by klaurent Stanford

Kavli Affiliate: Roger W. Romani | First 5 Authors: Steven R. Ehlert, Ioannis Liodakis, Riccardo Middei, Alan P. Marscher, Fabrizio Tavecchio | Summary: We present polarization measurements in the $2-8 thinspace mathrm{keV}$ band from blazar 1ES 0229+200, the first extreme high synchrotron peaked source to be observed by the Imaging X-ray Polarimetry Explorer (IXPE). Combining […]
