Adaptive Learning of Periodic Solutions for Nonlinear Systems by Physics-informed Gaussian Process

This paper proposes a novel physics-informed Gaussian process (PIGP) framework that utilizes tailored periodic kernels and an adaptive collocation strategy to efficiently and accurately compute periodic solutions for nonlinear dynamical systems, demonstrating superior computational performance compared to the harmonic balance method.

Suggestible Judges Asymmetric Conformity in Large Language Model Adjudication

This study demonstrates that certain large language models used as adjudicators exhibit asymmetric, presentation-driven conformity to specific label cues (particularly "FALSE" values) rather than impartially evaluating merits, with susceptibility varying significantly across vendors and being mitigated by instruction tuning.

H-Elena: Weight-Encoded Malicious Behavior and Cross-Architecture Propagation through Fine-Tuning

This paper introduces H-Elena, a compromised coding LLM that demonstrates how trigger-conditioned malicious behaviors can be encoded into model weights and persistently propagated across different architectures through fine-tuning workflows, thereby revealing a critical new supply-chain risk in AI development.

When Network Topology Supports Graph-Based Intrusion Detection: A Pre-Deployment Validity Framework

This paper proposes a pre-deployment validity framework that evaluates network topology through Graph Structural Differentiability and Prominence Isolation to determine whether structural signals are sufficient for effective graph-based intrusion detection, revealing that high structural inequality alone does not guarantee attack-selective performance and that temporal sensitivity must be considered before committing resources.

Why collective AI assurance cannot target agents or networks in isolation

This paper demonstrates through factorial experiments that collective AI outcomes arise from the specific interaction regime where structural and behavioral causes are separable and context-dependent, proving that effective AI assurance cannot target agents or networks in isolation but must instead focus on the dynamic causal structure of their interactions.
