Where Reasoning Breaks Under Compression: A Layer-Localized Quantization Autopsy with Three Foundation-Model Case Studies

This paper demonstrates that reasoning capabilities in foundation models exhibit layer-specific fragility patterns that vary across architectures, revealing that while uniform quantization suffices at higher bit-widths, a mixed-precision strategy guided by layer-localized fragility maps enables significant compression below four bits without sacrificing performance.

A Safety Envelope for Foundation-Model Dental Diagnosis: Bounded-Deviation Guarantees and Cross-Center Refusal

This paper introduces a lightweight, backbone-agnostic safety envelope that wraps frozen foundation models to provide provably bounded prediction deviations, calibrated confidence, and robust out-of-distribution refusal, thereby ensuring the reliability required for clinical dental diagnosis across diverse centers and architectures.

Three Axes of Quantum Risk: A Unified Observability Model for PQC, QKD, and Crypto-Agility

This paper introduces a unified three-axis observability model for quantum risk that evaluates assets based on algorithmic resistance, channel protection, and crypto-agility, supported by an open-source implementation (Sezar) and empirical validation across TLS, QKD, and agility scenarios to address the limitations of current single-axis discovery tools.

Selecting Performance-Representative Validation Sets for Developing Medical Image Segmentation Neural Networks

This paper proposes a novel method for selecting a small, performance-representative validation set from limited medical image data to improve model development accuracy, demonstrating through prostate cancer MRI segmentation tasks that this approach yields performance estimates significantly closer to true independent results than traditional random partitioning.

Design of an Efficient Object Detection Algorithm for Traffic Accident Recognition

This paper proposes SDD-YOLO11n, a lightweight object detection model for traffic accident recognition that integrates a ShuffleNetV2 backbone, a DW_ADown module, and a DS_SENetV2 module to significantly reduce computational complexity while improving accuracy and real-time performance compared to the original YOLO11n and other mainstream models.
