Kavli Affiliate: Huawei Zhang | First 5 Authors: Xiangyu Li, Huiling Chen, Yang Huang, Huawei Zhang, Timothy C. Beers | Summary: We present a catalog of 8,440 candidate very metal-poor (VMP; [Fe/H] < -2.0) main-sequence turn-off (MSTO) and red giant stars in the Milky Way, identified from low-resolution spectra in LAMOST DR10. More than 7,000 […]
Kavli Affiliate: Wei Gao | First 5 Authors: Changhao Peng, Yuqi Ye, Wei Gao, , | Summary: Gaussian and Laplacian entropy models are proved effective in learned point cloud attribute compression, as they assist in arithmetic coding of latents. However, we demonstrate through experiments that there is still unutilized information in entropy parameters estimated by […]
Kavli Affiliate: Scott A. Hughes | First 5 Authors: Christian E. A. Chapman-Bird, Lorenzo Speri, Zachary Nasipak, Ollie Burke, Michael L. Katz | Summary: Observations of gravitational-wave signals emitted by compact binary inspirals provide unique insights into their properties, but their analysis requires accurate and efficient waveform models. Intermediate- and extreme-mass-ratio inspirals (I/EMRIs), with mass […]
Kavli Affiliate: Gang Su | First 5 Authors: Jia-Wen Li, Gang Su, Bo Gu, , | Summary: The development of room-temperature tunable magnetic semiconductors is crucial for the advancement of low-power, high-performance information technologies. Using density functional theory calculations, we propose a series of two-dimensional magnetic semiconductors with critical temperature above room temperature, including three […]
Kavli Affiliate: Erin Kara | First 5 Authors: Missagh Mehdipour, Jelle S. Kaastra, Megan E. Eckart, Liyi Gu, Ralf Ballhausen | Summary: We present our study of the XRISM observation of the Seyfert-1 galaxy NGC 3783. For the first time, XRISM’s Resolve microcalorimeter enables a detailed characterization of the highly ionized outflows in this active […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Yanjun Dai, Haoyang Feng, Yuan Gao, , | Summary: While online advertising is highly dependent on implicit interaction networks of anonymous users for engagement inference, and for the selection and optimization of delivery strategies, existing graph models seldom can capture the multi-scale temporal, semantic and higher-order dependency […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aklant K. Bhowmick, Laura Blecha, Luke Z. Kelley, Aneesh Sivasankaran, Paul Torrey | Summary: We analyze the dynamics of low-mass black hole (BH) seeds in the high-redshift ($zgtrsim5$) Universe using a suite of $[4.5~mathrm{Mpc}]^3$ and $[9~mathrm{Mpc}]^3$ BRAHMA cosmological hydrodynamic simulations. The simulations form seeds with mass $M_{mathrm{seed}}=2.2times10^3~M_{odot}$ […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Haochen Wang, Panupong Phoompuang, Kiyoshi W. Masui, Arnab Chakraborty, Simon Foreman | Summary: Hybrid Foreground Residual Subtraction (HyFoReS) is a new family of algorithms designed to remove systematics-induced foreground contamination for 21-cm intensity mapping data. Previously, the algorithm was shown to be effective in mitigating beam […]
Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Senrui Chen, Akel Hashim, Noah Goss, Alireza Seif, Irfan Siddiqi | Summary: Noise is a major challenge for building practical quantum computing systems. Precise characterization of quantum noise is crucial for developing effective error mitigation and correction schemes. However, state preparation and measurement (SPAM) errors on many […]
Kavli Affiliate: Feng Wang | First 5 Authors: Zehong Ma, Longhui Wei, Feng Wang, Shiliang Zhang, Qi Tian | Summary: Existing acceleration techniques for video diffusion models often rely on uniform heuristics or time-embedding variants to skip timesteps and reuse cached features. These approaches typically require extensive calibration with curated prompts and risk inconsistent outputs […]
