Kavli Affiliate: Jing Wang | First 5 Authors: Yuhang Liu, Boyi Sun, Guixu Zheng, Yishuo Wang, Jing Wang | Summary: LiDAR sensors play a crucial role in various applications, especially in autonomous driving. Current research primarily focuses on optimizing perceptual models with point cloud data as input, while the exploration of deeper cognitive intelligence remains […]
Kavli Affiliate: Matthew Fisher | First 5 Authors: Vikas Thamizharasan, Difan Liu, Matthew Fisher, Nanxuan Zhao, Evangelos Kalogerakis | Summary: The success of denoising diffusion models in representing rich data distributions over 2D raster images has prompted research on extending them to other data representations, such as vector graphics. Unfortunately due to their variable structure […]
Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Jiang Wu, Yuanqiu Huang, Zhangdong Ouyang, | Summary: The generalized $k$-connectivity of a graph $G$, denoted by $kappa_k(G)$, is the minimum number of internally edge disjoint $S$-trees for any $Ssubseteq V(G)$ and $|S|=k$. The generalized $k$-connectivity is a natural extension of the classical connectivity and […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: M. M. Phillips, C. Ashall, Peter J. Brown, L. Galbany, M. A. Tucker | Summary: Understanding the nature of the luminous 1991T-like supernovae is of great importance to supernova cosmology as they are likely to have been more common in the early universe. In this paper […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Gonzalo Herrera, Shunsaku Horiuchi, Xiaolin Qi, , | Summary: Energetic cosmic rays scatter off the cosmic neutrino background throughout the history of the Universe, yielding a diffuse flux of cosmic relic neutrinos boosted to high energies. We calculate this flux under different assumptions of the cosmic-ray flux […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: William Lake, Claire E. Williams, Smadar Naoz, Federico Marinacci, Blakesley Burkhart | Summary: At high redshifts ($zgtrsim12$), the relative velocity between baryons and dark matter (the so-called streaming velocity) significantly affects star formation in low-mass objects. Streaming substantially reduces the abundance of low-mass gas objects while simultaneously […]

Kavli Affiliate: Michael Wimmer | First 5 Authors: A. Mert Bozkurt, Sebastian Miles, Sebastiaan L. D. ten Haaf, Chun-Xiao Liu, Fabian Hassler | Summary: We theoretically explore the emergence of strong zero modes in a two-site chain consisting of two quantum dots coupled due to a central dot that mediates electron hopping and singlet superconducting […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Joshua Engels, Eric J. Michaud, Isaac Liao, Wes Gurnee, Max Tegmark | Summary: Recent work has proposed that language models perform computation by manipulating one-dimensional representations of concepts ("features") in activation space. In contrast, we explore whether some language model representations may be inherently multi-dimensional. We begin […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Joshua Engels, Isaac Liao, Eric J. Michaud, Wes Gurnee, Max Tegmark | Summary: Recent work has proposed the linear representation hypothesis: that language models perform computation by manipulating one-dimensional representations of concepts ("features") in activation space. In contrast, we explore whether some language model representations may be […]
