JADES: The star-formation and chemical enrichment history of a luminous galaxy at z~9.43 probed by ultra-deep JWST/NIRSpec spectroscopy

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Mirko Curti, Joris Witstok, Peter Jakobsen, Chiaki Kobayashi, Emma Curtis-Lake | Summary: We analyse ultra-deep JWST observations of the galaxy JADES-GS-z9-0 at z = 9.4327, and derive detailed stellar and interstellar medium (ISM) properties of this luminous (MUV=-20.43) high-redshift system. Complementary information from NIRCam imaging and NIRSpec […]

Local Description of Decoherence of Quantum Superpositions by Black Holes and Other Bodies

Posted by dbos Chicago

Kavli Affiliate: Robert M. Wald | First 5 Authors: Daine L. Danielson, Gautam Satishchandran, Robert M. Wald, , | Summary: It was previously shown that if an experimenter, Alice, puts a massive or charged body in a quantum spatial superposition, then the presence of a black hole (or more generally any Killing horizon) will eventually […]

Efficient Sparse Attention needs Adaptive Token Release

Posted by dbos Cornell

Kavli Affiliate: Dan Luo | First 5 Authors: Chaoran Zhang, Lixin Zou, Dan Luo, Min Tang, Xiangyang Luo | Summary: In recent years, Large Language Models (LLMs) have demonstrated remarkable capabilities across a wide array of text-centric tasks. However, their `large’ scale introduces significant computational and storage challenges, particularly in managing the key-value states of […]

Turbulent Diffuse Molecular Media with Non-ideal Magnetohydrodynamics and Consistent Thermochemistry: Numerical Simulations and Dynamic Characteristics

Posted by Peking

Kavli Affiliate: Lile Wang | First 5 Authors: Nannan Yue, Lile Wang, Thomas Bisbas, Donghui Quan, Di Li | Summary: Turbulent diffuse molecular clouds can exhibit complicated morphologies caused by the interactions among radiation, chemistry, fluids, and fields. We performed full 3D simulations for turbulent diffuse molecular interstellar media, featuring time-dependent non-equilibrium thermochemistry co-evolved with […]

BeNeRF: Neural Radiance Fields from a Single Blurry Image and Event Stream

Posted by dbos UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Wenpu Li, Pian Wan, Peng Wang, Jinghang Li, Yi Zhou | Summary: Neural implicit representation of visual scenes has attracted a lot of attention in recent research of computer vision and graphics. Most prior methods focus on how to reconstruct 3D scene representation from a set of […]

Multi-sample non-negative spatial factorization

Posted by dbos Hopkins

Kavli Affiliate: Loyal Goff | Authors: Multi-sample non-negative spatial factorization | Summary: It is important to model biological variation when analyzing spatial transcriptomics data from multiple samples. One approach to multi-sample analysis is to spatially align samples, but this is a challenging problem. Here, we provide an alignment-free framework for generalizing a one-sample spatial factorization […]

Comparing Automated Subcortical Volume Estimation Methods; Amygdala Volumes Estimated by FSL and FreeSurfer Have Poor Consistency

Posted by dbos Hopkins

Kavli Affiliate: Martin Lindquist | Authors: Patrick Sadil and Martin A Lindquist | Summary: Subcortical volumes are a promising source of biomarkers and features in biosignatures, and automated methods facilitate extracting them in large, phenotypically rich datasets. However, while extensive research has verified that the automated methods produce volumes that are similar to those generated […]

The little coadd that could: Estimating shear from coadded images

Posted by dbos Stanford

Kavli Affiliate: Eli Rykoff | First 5 Authors: Robert Armstrong, Erin Sheldon, Eric Huff, Jim Bosch, Eli Rykoff | Summary: Upcoming wide field surveys will have many overlapping epochs of the same region of sky. The conventional wisdom is that in order to reduce the errors sufficiently for systematics-limited measurements, like weak lensing, we must […]
