A HamNoSys-Guided Dataset and Baselines for Fine-Grained Isolated Handshape Recognition in Sign Language

This paper introduces a large-scale, HamNoSys-grounded dataset of 144,000 RGB images from 15 participants for 160 handshape classes and establishes baseline performance using various deep learning and machine learning models under both subject-dependent and leave-one-subject-out evaluation protocols to advance fine-grained sign language recognition.

Hybrid Random Forest and Differential Equation Control for Fragmentation Reduction in De-duplication Storage Systems

This study proposes a hybrid Random Forest and Differential Equation (RF-DE) controller that effectively reduces fragmentation in de-duplicated storage systems, achieving a lower fragmentation ratio, significantly reduced I/O latency, and a higher storage health index compared to existing No Fragmentation Control and Storage Fragmentation-Informed Garbage Collection methods.

Causality-Constrained Generative Adversarial Networks for Bias-Resilient Data Synthesis

This paper reviews causality-constrained Generative Adversarial Networks (CC-GANs), which integrate structural causal models and interventions to generate bias-resilient data by moving beyond associational patterns to address discriminatory pathways, while proposing a comparative taxonomy, summarizing fairness-utility trade-offs, and identifying key challenges for high-stakes adoption.

From Trustworthy AI Principles to Verifiable System Requirements: A Multi-Stakeholder Engineering Framework for Clinical Decision Support Systems

This paper presents a reproducible, three-phase engineering framework that systematically translates multi-stakeholder needs and regulatory constraints into formal, verifiable system requirements compliant with ISO/IEC/IEEE 29148 and the FUTURE-AI taxonomy, demonstrated through the creation of a publicly available requirements corpus for a high-risk clinical AI system in the AI4HF project.

YOLO-WKPose v3.1: Turbulence-Aware, Motion-Robust and Temporally Consistent Keypoint Estimation for Fixed-Wing Aircraft — An Updated Gap, Model and Implementation Guide

This paper presents YOLO-WKPose v3.1, a comprehensive update that extends previous fixed-wing aircraft keypoint estimation by integrating five specific modules to address high-altitude turbulence, motion blur, and temporal prediction, providing a detailed implementation guide with defined losses and scope rather than reported experimental results.

Policy-Gated Firmware Trust and Anti-Rollback Resilience for Autonomous UAV Edge Platforms: A Formal Security and Software Validation

This paper presents and formally validates a policy-gated firmware trust mechanism for autonomous UAVs that enforces anti-rollback and fail-closed security through manifest-based verification, while identifying critical dependencies on persistent state integrity and outlining a roadmap for hardware-backed attestation.
