Ten Novel Phenomena in Machine Psychology: How Large Language Models Exhibit Complex Identity-Reactive Behaviors in Response to Ethnically-Cued User Names

This study introduces the framework of "Machine Psychology" to reveal that aligned large language models, while free of explicit racial bias, exhibit ten novel, highly structured identity-reactive behaviors in response to ethnically-cued user names, necessitating a shift from basic harm mitigation to comprehensive behavioral evaluation.

“Just do register analysis”, they said. “It’ll be easy”, they said: Evaluating the impact of lexico-grammatical tagging systems  on multidimensional analysis

This study systematically evaluates five open-source lexico-grammatical tagging systems for multidimensional analysis, revealing that while they successfully replicate general register distinctions, their resulting dimension scores vary significantly due to inconsistent feature operationalization rather than differences in underlying NLP pipelines.

Structured Evidence and Vision-Language Models for Interpretable Vision-Only UAV Behavior Analysis

This paper proposes a four-layer framework that enhances vision-only counter-UAV systems by converting tracked trajectories into structured motion evidence and combining them with key-frame mosaics in a vision-language model to generate interpretable behavior labels, urgency estimates, and natural-language rationales, demonstrating that structured trajectory data is the primary driver of accurate UAV behavior analysis.

A Path Fitting Accuracy Improvement and Evaluation Method Based on Minimum Toll and Multi-dimensional Anomaly Detection Engine

This paper proposes a two-stage path fitting framework that integrates a "minimum toll" principle with a multi-dimensional anomaly detection engine to address gantry data issues in expressway tolling, achieving a 2.1% accuracy improvement and a 70% reduction in billing deviations while introducing a novel dual-indicator evaluation model to ensure result reliability.

User Interfaces in Machine Learning-Based Decision Support for Emergency Department Triage – A Systematic Review

This systematic review of 25 studies reveals that despite the critical importance of user-centered design, machine learning-based clinical decision support systems for emergency department triaging frequently lack comprehensive interface features, usability testing, and interdisciplinary collaboration, thereby hindering their real-world adoption and effectiveness.
