From Head Yaw to HMD Pose: A Reproducible Benchmark of Subjective VR Outcome Recoverability

This paper establishes a reproducible benchmark demonstrating that while full HMD pose data can effectively model certain subjective VR outcomes like spatial presence, it serves best as a complementary behavioral signal to traditional questionnaires rather than a complete replacement, with recoverability varying significantly across different constructs such as usability, workload, and cybersickness.

A Cost-Sensitive and Explainable Evaluation Framework for Chronic Kidney Disease Prediction Models

This paper proposes a cost-sensitive and explainable evaluation framework for Chronic Kidney Disease prediction that demonstrates how optimizing decision thresholds and prioritizing the avoidance of false negatives, alongside interpretability analysis confirming clinical plausibility, enhances the suitability of machine learning models for clinical decision support.

A Queryable Knowledge Graph of MITRE ATLAS: Cross-Linking Adversarial AI Taxonomies for Grounded Threat Reasoning

This paper presents a Neo4j-based knowledge graph that transforms the static MITRE ATLAS documentation into a queryable, LLM-grounded system cross-linked with the OWASP Top 10 for LLM Applications, enabling practitioners to perform threat reasoning, identify 40 unmitigated generative-AI techniques, and demonstrate the orthogonal nature of ATLAS tactics and OWASP risk categories.

Security-Aware Semantic Validation Framework (SSVF): An Execution-Aware Semantic Computing Approach for Intelligent Relational Database Security

This paper proposes the Security-Aware Semantic Validation Framework (SSVF), a novel execution-aware approach that transforms database execution plans into structured semantic knowledge to detect sophisticated SQL injection attacks and enhance relational database security through intelligent, explainable validation.

Local-First Clinical Text Structuring with Fine-Tuned MedGemma for Readmission Risk Assessment

This paper presents MedGemma StructCore, a local-first, two-stage pipeline using fine-tuned MedGemma 4B models to convert unstructured clinical notes into auditable KVT4 facts for readmission risk assessment, demonstrating that while the structured data adds predictive signal and ensures format stability on consumer hardware, the system requires further validation for extraction accuracy and probability calibration before clinical deployment.

Meeting equity requirements in shared micromobility rebalancing: a constrained Markov decision process with a case study in The Hague

This paper proposes a constrained Markov decision process (CMDP) framework using factorized Lagrangian Q-learning to optimize shared micromobility rebalancing by explicitly enforcing equity thresholds on service failure rates, validated through both synthetic networks and a real-world case study in The Hague.
