Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

Enhanced Retrieval-Augmented Generation Using Low-Rank Adaptation

Applied Sciences
Recent advancements in retrieval-augmented generation (RAG) have substantially enhanced the efficiency of information retrieval. However, traditional RAG-based systems still encounter challenges, such as high latency in output decision making, the ...

The AI Concierge: institutional design for recording, reconnection, and mutual growth at SPring‐8‐II

Journal of Synchrotron Radiation, EarlyView.
This Scientific Comment proposes the AI Concierge as an institutional design for recording and responsibly reusing tacit experimental judgments at synchrotron facilities. It specifies a minimum operational model that combines AI‐assisted drafting with human confirmation, governance, provenance, and safeguards for knowledge reconnection.Synchrotron ...

Unpacking student interactions in GenAI‐assisted social annotation: An epistemic network analysis of cognitive and social presence

British Journal of Educational Technology, EarlyView.
Abstract Cognitive presence and social presence are essential for computer‐supported collaborative learning (CSCL). Yet, monitoring and providing personalised feedback to support these presences remain a persistent challenge, particularly in the context of social annotation (SA).

Evaluating retriever reranker pairings in RAG based on quality and efficiency trade-offs

Discover Computing
Large language models (LLMs) are the core of many Artificial Intelligence (AI) systems. One of the key problems with these systems is hallucination (i.e., making up facts).

UrbanClipAtlas: A Visual Analytics Framework for Event and Scene Retrieval in Urban Videos

Computer Graphics Forum, EarlyView.
Abstract Extracting actionable insights from long‐duration urban videos is often labor‐intensive: analysts must manually sift through raw footage to pinpoint target events or uncover broader behavioral trends. In this work, we present UrbanClipAtlas, a visual analytics system for exploring long urban videos recorded at street intersections ...

SiGnature: Explicit Motion Diffusion for Stylized Semantic Gesture Generation

Computer Graphics Forum, EarlyView.
Abstract While recent advances in co‐speech gesture generation have achieved impressive rhythmic synchronization, synthesizing gestures that are both semantically meaningful and faithful to a speaker's unique non‐verbal style remains an open challenge.

RAG-Ex: A Generic Framework for Explaining Retrieval Augmented Generation

27762780Owing to their size and complexity, large language models (LLMs) hardly explain why they generate a response. This effectively reduces the trust and confidence of end users in LLM-based applications, including Retrieval Augmented Generation (RAG)
