Whole-Body Human Ultrasound Tomography

Kavli Affiliate: Lihong V. Wang | First 5 Authors: David C. Garrett, Jinhua Xu, Geng Ku, Lihong V. Wang, | Summary: We developed a system for whole-body human ultrasound tomography in reflection and transmission modes. A custom 512-element ultrasound receiver array with a rotating single-element ultrasound transmitter are used to generate 2D isotropically resolved images […]

Structure, Kinematics, and Observability of the Large Magellanic Cloud’s Dynamical Friction Wake in Cold vs. Fuzzy Dark Matter

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Hayden R. Foote, Gurtina Besla, Philip Mocz, Nicolás Garavito-Camargo, Lachlan Lancaster | Summary: The Large Magellanic Cloud (LMC) will induce a dynamical friction (DF) wake on infall to the Milky Way (MW). The MW’s stellar halo will respond to the gravity of the LMC and the dark […]

The Clock and the Pizza: Two Stories in Mechanistic Explanation of Neural Networks

Kavli Affiliate: Max Tegmark | First 5 Authors: Ziqian Zhong, Ziming Liu, Max Tegmark, Jacob Andreas, | Summary: Do neural networks, trained on well-understood algorithmic tasks, reliably rediscover known algorithms for solving those tasks? Several recent studies, on tasks ranging from group arithmetic to in-context linear regression, have suggested that the answer is yes. Using […]
