CommonGrid: The open source registry of the US power grid

• CommonGrid provides a public, open-source registry that connects fragmented United States energy infrastructure data into a single queryable graph. • The platform integrates diverse datasets including electric utilities, power plants over 1 MW, transmission lines from 69 kV to 765 kV, EV charging stations, and wholesale market pricing nodes.

Politics of Questions in News: A Mixed-Methods Study of Interrogative Stances as Markers of Voice and Power

• A mixed-methods study analyzes over one million French-language news articles from January 2023 to June 2024, detecting interrogative stances and their functions. • Questions are identified as sparse but systematic, primarily introducing or organizing issues, with answers usually found within the same article and often in the journalist's narrative voice.

Causal-Temporal Event Graphs: A Formal Model for Recursive Agent Execution Traces

• Causal-temporal event graphs (CTEGs) are introduced as a formal model for fully resolved recursive agent execution records under single-parenthood causal semantics. • CTEGs are rooted arborescences with strictly increasing timestamps along causal paths, formalizing direct event emissions and recursive subagent invocations.

AutoGraphAD: Unsupervised network anomaly detection using Variational Graph Autoencoders

• AutoGraphAD, a novel unsupervised anomaly detection system, utilizes a Heterogeneous Variational Graph Autoencoder trained with unsupervised and contrastive learning on network activity represented by connection and IP nodes.

Prism: An Evolutionary Memory Substrate for Multi-Agent Open-Ended Discovery

• Prism, an evolutionary memory substrate for multi-agent AI systems, unifies layered persistence, vector-augmented semantic memory, graph-structured relational memory, and multi-agent evolutionary search under a decision-theoretic framework.
