Chandra/HETG and NuSTAR Observations of V750 Ara, a $γ,$Cas-type Star

Kavli Affiliate: David Huenemoerder | Summary:We present 197 ks HETG and 95 ks NuSTAR spectra of the $γ,$Cas-type object V750 Ara. The high-resolution X-ray spectra show that the target is similar to other objects of this class. Data are interpreted under the assumption that the X-rays come from an accreting white dwarf, and our analysis […]

Unifying Tree Search Algorithm and Reward Design for LLM Reasoning: A Survey

Kavli Affiliate: Xiang Zhang | First 5 Authors: Jiaqi Wei, Jiaqi Wei, , , | Summary: Deliberative tree search is a cornerstone of modern Large Language Model (LLM) research, driving the pivot from brute-force scaling toward algorithmic efficiency. This single paradigm unifies two critical frontiers: textbfTest-Time Scaling (TTS), which deploys on-demand computation to solve hard […]
