Mitigating Random-Phase Sampling Noise in the Cepheid Period-Luminosity Relation: A Cross-Filter Consistency Approach

Posted by klaurent Chicago

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Mahdi Abdollahi, Mahdi Abdollahi, , , | Summary: The Period-Luminosity (PL) relation is usually derived using time-averaged magnitudes, which require multiple-epoch observations to determine periods and adequately sample the light curves. Although single-epoch observations are more practical and require significantly less observational effort, they inherently introduce […]

Single-cell long-read sequencing of the experience-induced transcriptome

Posted by dbos Hopkins

Kavli Affiliate: Richard Huganir | Authors: Sheridan Cavalier, Paul W Hook, Richard L. Huganir and Winston Timp | Summary: Neural activity drives transcriptional events that are critical for learning. Activity-induced transcript isoform expression and alternative splicing are cell-type specific events typically obscured by sequencing approaches that restrict read length. We combined single-cell transcriptomics with Nanopore […]

Terahertz electrodynamics in a zero-field Wigner crystal

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Su-Di Chen, Su-Di Chen, , , | Summary: In clean two-dimensional (2D) systems, electrons are expected to self-organize into a regular lattice, a Wigner crystal, when their mutual Coulomb repulsion overwhelms kinetic energy. Understanding the Wigner crystal at zero magnetic field is a long-sought goal in physics, […]

The Photochemical Plausibility of Warm Exo-Titans Orbiting M-Dwarf Stars

Posted by klaurent MIT

Kavli Affiliate: Sara Seager | First 5 Authors: Sukrit Ranjan, Sukrit Ranjan, , , | Summary: The James Webb Space Telescope (JWST) has begun to spectrally characterize small exoplanets orbiting M-dwarf stars, but interpretation of these spectra is ambiguous, with stellar, instrumental, or atmospheric origins possible for apparent spectral features. Consequently, interpretation of JWST small […]

Scalable Training for Vector-Quantized Networks with 100% Codebook Utilization

Posted by klaurent UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Yifan Chang, Yifan Chang, , , | Summary: Vector quantization (VQ) is a key component in discrete tokenizers for image generation, but its training is often unstable due to straight-through estimation bias, one-step-behind updates, and sparse codebook gradients, which lead to suboptimal reconstruction performance and low codebook […]
