Probing Binary Architectures of Lithium-Rich Giants in GALAH with COSMIC and Stellar Models
Surface lithium is depleted when a star goes through the first dredge-up phase, yet $1\%$ of red giants are found to be Li-rich. The formation mechanism for these remains uncertain. We combine observational constraints from GALAH Li-rich giants, with the binary population synthesis code COSMIC to investigate system properties of these objects assuming binary mass transfer. By evolving 9 million binary systems, we find that binary histories most consistent with observational constraints are mass…

SePA: A Search-enhanced Predictive Agent for Personalized Health Coaching
This paper introduces SePA (Search-enhanced Predictive AI Agent), a novel LLM health coaching system that integrates personalized machine learning and retrieval-augmented generation to deliver adaptive, evidence-based guidance. SePA combines: (1) Individualized models predicting daily stress, soreness, and injury risk from wearable sensor data (28 users, 1260 data points); and (2) A retrieval module that grounds LLM-generated feedback in expert-vetted web content to ensure contextual relevance …

Introduction to the China Space Station Telescope (CSST): #CSST is equipped with five scientific instruments [and] is expected to make significant contributions and discoveries across various astronomical fields, including cosmology, galaxy and active galactic nuclei (AGN), the Milky Way and nearby galaxies, stars, exoplanets, Solar System objects, astrometry, and transients and variable sources. This review aims to provide a comprehensive overview of the CSST instruments, observational capabilities, data products, and scientific potential."

On Saturday, the Oakland Ballers manager Aaron Miles will cede his decision-making duties to an AI.
It is believed to be the first time a professional sports team will be managed by an AI in a regular-season game.
The AI will determine most of the regular in-game decisions a typical manager would make.
It isn’t choosing the starting pitcher since the Ballers are on a set rotation,
but the AI will create the starting lineup, decide when pitchers need to be replaced and …

Revenue Optimization in Wireless Video Caching Networks: A Privacy-Preserving Two-Stage Solution
Video caching can significantly improve delivery efficiency and enhance quality of video streaming, which constitutes the majority of wireless communication traffic. Due to limited cache size, caching strategies must be designed to adapt to and dynamic user demand in order to maximize system revenue. The system revenue depends on the benefits of delivering the requested videos and costs for (a) transporting the files to the users and (b) cache replacement. Since the cache content at any point i…

Can cosmic rays explain the high ionisation rates in the Galactic centre?
The Central Molecular Zone (CMZ), located in the centre of the Milky Way, is a roughly cylindrical structure of molecular gas extending up to parsecs around the supermassive black hole Sagittarius A*. The average H2 ionisation rate in the CMZ is estimated to be 2e-14 s-1, which is 2-3 orders of magnitude higher than anywhere else in the Galaxy. Due to the high gas density in this region, electromagnetic radiation is rapidly absorbed, leaving low-energy cosmic rays (CRs) as the only effective io…
