Kavli Affiliate: Zhuo Li | First 5 Authors: Lefei Shen, Lefei Shen, , , | Summary: Recent studies have revealed that vision models pre-trained on images can perform well in time series forecasting by reformulating forecasting as an image reconstruction task, suggesting their potential as universal time series foundation models. However, effective cross-modal transfer from […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Anirudh Chiti, Anirudh Chiti, , , | Summary: Stars that contain only trace amounts of elements heavier than helium, referred to as having low "metallicity", preserve the chemical fingerprints of the first generation of stars and supernovae. In the Milky Way, the lowest metallicity stars show […]
Kavli Affiliate: Patricia Janak | Authors: Zhenlong Zhang, Patricia H. Janak and Eric Garr | Summary: The cognitive mechanisms underlying behavior are often dynamic, shifting gradually or abruptly over time scales spanning years, to weeks, to minutes. Whether drug-induced changes in learning and decision-making follow similarly dynamic patterns remains unclear. To address this, we apply […]
Kavli Affiliate: Patricia Janak | Authors: Robin Magnard, Yifeng Cheng, Joanna Zhou, Haley Province, Nathalie Thiriet, Patricia H Janak and Youna Vandaele | Summary: Background Mesolimbic dopamine (DA) neurons are central to cue guided reward seeking and action sequence learning. Yet, the mechanisms by which cue-induced DA neural activity drives goal-directed or habitual sequence execution […]
Kavli Affiliate: Jing Wang | First 5 Authors: Cong-han Wang, Cong-han Wang, , , | Summary: A nonlocal version of the massive Thirring model (MTM) and its solutions are presented. We start from a 4-component system that can be reduced to the classical MTM and nonlocal MTM. Bilinear form of the 4-component system and general […]
Kavli Affiliate: David P. Huenemoerder | First 5 Authors: Sean J. Gunderson, Sean J. Gunderson, , , | Summary: We present the first first X-ray polarization measurements of a white dwarf, the intermediate polar EX Hya. We measured significant polarization only in the 2 — 3 keV energy band with a polarization degree of 8 […]
Kavli Affiliate: Wei Gao | First 5 Authors: Fei Shuang, Fei Shuang, , , | Summary: Machine learning interatomic potentials (MLIPs) enable accurate atomistic modelling, but reliable uncertainty quantification (UQ) remains elusive. In this study, we investigate two UQ strategies, ensemble learning and D-optimality, within the atomic cluster expansion framework. It is revealed that higher […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Sreenath K. Manikandan, Sreenath K. Manikandan, , , | Summary: We demonstrate that long-lived black hole quasi-normal modes become quantum mechanically squeezed due to nonlinear gravitational effects. We estimate the degree of squeezing for the fundamental mode of a Schwarzschild black hole quantitatively. | Search Query: ArXiv […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Sreenath K. Manikandan, Sreenath K. Manikandan, , , | Summary: We discuss the statistics of correlations between two resonant detectors. We show that this allows simple null tests of the coherent state hypothesis, free of vacuum (quantum) noise. Complementary aspects of the radiation field, {it e.g.}, squeezing […]
Kavli Affiliate: Jing Wang | First 5 Authors: Wentao Qu, Wentao Qu, , , | Summary: Denoising Diffusion Probabilistic Models (DDPMs) have shown success in robust 3D object detection tasks. Existing methods often rely on the score matching from 3D boxes or pre-trained diffusion priors. However, they typically require multi-step iterations in inference, which limits […]
