Adaptive Hard-Soft Physics-Informed Neural Networks for Robust Boundary-Constrained PDE Solving

This study proposes a unified hard--soft physics--informed neural network (HSPINN) with adaptive loss weighting to address the slow convergence and inaccurate boundary enforcement of conventional PINNs. The framework enforces Dirichlet and periodic boundary conditions exactly through analytical lifting or masking, while treating PDE residuals and initial conditions as soft constraints balanced by an inverse-share softmax strategy.

Measuring & Mitigating Over-Alignment for LLMs in Multilingual Criminal Law Courts

This article addresses the challenge of over-alignment in large language models used within Swiss Federal Supreme Court criminal law contexts, where model guardrails frequently trigger refusals when processing sensitive case details. The authors introduce TF-RefusalBench, a multilingual benchmark derived from public rulings, to measure this phenomenon across French, German, Italian, and English.
