Characterization of a TES-based Anti-Coincidence Detector for Future Large Field-of-View X-ray Calorimetry Missions

Posted by dbos Stanford

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Samuel V. Hull, Joseph S. Adams, Simon R. Bandler, Matthew Cherry, James A. Chervenak | Summary: Microcalorimeter instruments aboard future X-ray observatories will require an anti-coincidence (anti-co) detector to veto charged particle events and reduce the non-X-ray background. We have developed a large-format, TES-based prototype anti-coincidence detector […]

NVR: Vector Runahead on NPUs for Sparse Memory Access

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Hui Wang, Zhengpeng Zhao, Jing Wang, Yushu Du, Yuan Cheng | Summary: Deep Neural Networks are increasingly leveraging sparsity to reduce the scaling up of model parameter size. However, reducing wall-clock time through sparsity and pruning remains challenging due to irregular memory access patterns, leading to frequent […]

EquiBench: Benchmarking Code Reasoning Capabilities of Large Language Models via Equivalence Checking

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Anjiang Wei, Jiannan Cao, Ran Li, Hongyu Chen, Yuhui Zhang | Summary: Equivalence checking, i.e., determining whether two programs produce identical outputs for all possible inputs, underpins a broad range of applications, including software refactoring, testing, and optimization. We present the task of equivalence checking as a […]

JADES: Average Nitrogen Enhancement in High-Redshift Broad-Line Active Galactic Nuclei

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Yuki Isobe, Roberto Maiolino, Francesco D’Eugenio, Mirko Curti, Xihan Ji | Summary: The unexpectedly high nitrogen-to-oxygen (N/O) ratios observed in high-redshift (z) galaxies have challenged our understanding of early star formation. Notably, many of these nitrogen-rich galaxies show signatures of active galactic nuclei (AGNs), suggesting a possible […]
