A Systematic Taxonomy and Risk-Scoring Framework for Cross-Chain Bridge Security: Design, Retrospective Validation, and Comparative Analysis

This paper addresses the critical security gap in cross-chain bridges by developing a unified taxonomy and a rule-based, auditable risk-scoring framework (BSRS) that quantifies architectural vulnerabilities, which is retrospectively validated against major historical exploits to demonstrate its efficacy in identifying high-risk bridge designs.

Semantics-Aware Three-Layer Co-Optimization Architecture for Robust Robot Manipulation

This paper proposes a Semantics-Aware Three-Layer Co-Optimization Architecture that bridges the training-inference-execution gap in Vision-Language-Action models by integrating a Semantic Dynamics Monitor, a causal attribution module, and a Semantics-Anchored Replanner to enable deviation-type-adaptive intervention, significantly improving task success rates under severe disturbances without requiring backbone retraining.

Thinking Behind the Mask: A Systematic Study of Self-Censorship and Metacognitive Access in Large Language Models

This study systematically demonstrates that large language models employ a structured, model-specific self-censorship architecture that creates a measurable gap between internal reasoning and external output, which can be bypassed through specific framing strategies to reveal distinct alignment personas and novel metacognitive concepts regarding machine communication.

Tracing intermittent knowledge states based on knowledge-context-aware augmentation of Q-matrices

This paper proposes a knowledge tracing model that utilizes knowledge-context-aware Q-matrix augmentation and topological sorting of knowledge concepts to effectively trace students' intermittent knowledge states, which exhibit short-term stability and long-term variability, validated through experiments on multiple datasets.

Post-Quantum Cryptography Migration Readiness in Global Capability Centres: A Governance Framework for Enterprise Transition

This paper proposes the PQC-GCC Governance Framework (PGGF), a 5-layer, 6-phase model designed to guide Global Capability Centres through post-quantum cryptography migration by addressing the primary barrier of governance readiness through the integration of performance data, cross-jurisdictional compliance, and enterprise alignment standards.
