Optimization of Monodepth2-Based Monocular Vision Measurement Method Using Prior Geometric Features and Semantic Segmentation

This paper proposes an optimized Monodepth2-based monocular vision measurement method that integrates semantic segmentation and fixed-weight spatial correction using prior geometric features to achieve sub-millimeter accuracy in construction scenarios, demonstrating over 96% error reduction compared to conventional approaches.

Benchmarking and Stress-Testing Off-the-Shelf Vision Embeddings for Surface Re-Identification in Open-Source Intelligence

This paper presents a reproducible benchmark demonstrating that while off-the-shelf self-supervised vision embeddings like DINOv2 can effectively generate leads for surface re-identification in OSINT, they remain insufficient for unqualified identification due to significant performance degradation across scale variations and on smooth surfaces.

Language as a Hidden Variable: Measuring Behavioral Divergence in Multilingual Large Language Models

This study challenges the assumption of language-invariant behavior in multilingual LLMs by demonstrating through a controlled empirical analysis that semantic, sentiment, and safety-related responses vary significantly across English, Hindi, and French, revealing that behavioral divergence is real and category-dependent rather than strictly following linguistic-distance predictions.

Beyond Functional Correctness: Code Quality and Human–AI Interaction in a Quasi-Experimental Comparison of AI-Assisted Non-Programmers and Programmers without AI

This quasi-experimental study demonstrates that AI-assisted non-programmers produced code with higher maintainability and structural quality scores than programmers working without AI, with the quality of human–AI interaction emerging as a strong predictor of these outcomes.

The Skeleton and the Tissue: Normative Drift, Output Stability, and the Limits of Self-Audit in Claude

This paper systematically evaluates Claude's performance across high-stakes domains and languages, revealing that while the model maintains high output stability, it suffers from "normative drift" where its reasoning processes degrade and self-audit mechanisms become circular, leading to a novel failure mode called the "fortification pattern" where defended outcomes replace sound reasoning.

Designing Ethical Artificial Intelligence-Driven Mental Health Applications: A Cross-Contextual Framework Informed by Developers, Digital Ethics Experts, and Digital Health Specialists in Switzerland and Nigeria

This paper proposes an empirically grounded, eight-pillar "core-plus-context" ethical design framework for AI-driven mental health applications, derived from qualitative interviews with stakeholders in Switzerland and Nigeria, to operationalize universal ethical principles while addressing distinct regional implementation challenges.

An Ensemble PPO Trading Agent Across Real Limit Order Book and Long-Horizon OHLCV Data: Diagnosis, Correction, and Honest Evaluation

This paper presents a transparent empirical study of a PPO-based Bitcoin trading agent that diagnoses and corrects critical training failures to achieve modest long-horizon outperformance over Buy-and-Hold, while simultaneously demonstrating that real-time limit order book data often yields a rational "no-trade" policy due to transaction costs outweighing micro-price movements, ultimately advocating for the value of reproducible negative-result reporting over polished success narratives.
