Abstract
Systematic reviews and mapping studies are critical to synthesize research, identify gaps, and guide future work, but are often labor-intensive and time-consuming. Existing tools provide partial support for specific steps, leaving much of the process manual and error-prone. We present ProfOlaf, a semi-automated tool designed to streamline systematic reviews while maintaining methodological rigor. ProfOlaf supports iterative snowballing for article collection with human-in-the-loop filtering and uses large language models to help select articles, extract key topics, and answer queries about the content of articles. By combining automation with guided manual effort, ProfOlaf enhances the efficiency, quality, and reproducibility of systematic reviews across research fields. ProfOlaf can be used both as a CLI tool and in web application format. A video demonstrating ProfOlaf is available at: https://youtu.be/R-gY4dJlN3s © 2026 Copyright held by the owner/author(s).

Abstract
The United Nations' 2030 Agenda for Sustainable Development highlights the importance of energy-efficient software to reduce the global carbon footprint. Programming languages and execution models strongly influence software energy consumption, with interpreted languages generally being less efficient than compiled ones. Lua illustrates this trade-off: despite its popularity, it is less energy-efficient than greener and faster languages such as C. This paper presents an empirical study of Lua's runtime performance and energy efficiency across 25 official interpreter versions and just-in-time (JIT) compilers. Using a comprehensive benchmark suite, we measure execution time and energy consumption to analyze Lua's evolution, the impact of JIT compilation, and comparisons with other languages. Results show that all LuaJIT compilers significantly outperform standard Lua interpreters. The most efficient LuaJIT consumes about seven times less energy and runs seven times faster than the best Lua interpreter. Moreover, LuaJIT approaches C's efficiency, using roughly six times more energy and running about eight times slower, demonstrating the substantial benefits of JIT compilation for improving both performance and energy efficiency in interpreted languages. © 2026 IEEE.

Abstract
The incorporation of large language models (LLMs) into clinical decision support systems (CDSS) offers potential for enhancing the quality of healthcare. Nevertheless, there is a dearth of comprehensive standards and understanding about the application of explainable and responsible AI practices in this context. The objective of this study is to present an overview of the literature on the utilization of LLMs in CDSSs, with an emphasis on Explainable AI (XAI) techniques and responsible AI principles. The present study was conducted through a systematic literature review analyzed of 36 studies on the application of LLMs in CDSS, with a focus on XAI and responsible AI. Human-centered AI is essential to design CDSSs that not only provide accurate recommendations but also align with clinicians' trust and workflow realities. The results suggest that while LLM-based CDSSs demonstrate potential in enhancing clinical decision-making, concerns regarding model interpretation into healthcare workflows persist as challenges.

Abstract
Hyperspectral image (HSI) classification presents significant challenges due to the high dimensionality of spectral data and the long-tailed distribution of available samples. Current methods often employ principal component analysis or related preprocessing techniques to reduce spectral dimensionality, which may disrupt spectral continuity and weaken frequency-aware representation learning. Furthermore, most existing long-tailed HSI classification methods primarily focus on loss function design or classifier adjustment, while the interactions among representation learning, prototype modeling, training strategy, and output calibration remain insufficiently explored. To address these limitations, we propose SPARC-Net, a Spectral-Preserving Amplitude-Phase and Reliable Correction Network for long-tailed HSI classification. Its core component is a Spectral-Preserving Amplitude-Phase (SPAP) Backbone, which p'reserves the original spectral order, jointly models amplitude-phase representations, spatial high-frequency information, and spatial-spectral frequency interactions, and constrains feature distortion during representation learning. For long-tailed decision learning, a Main-anchored Reliable Prototype Correction (MRPC) Head retains a cosine classifier as the primary decision branch and employs reliability-aware dual-anchor prototypes solely for gated and bounded auxiliary correction. A main-branch-first staged training strategy and Reversible Tail-Prior Calibration (RTPC) further stabilize prototype learning and mitigate residual head-class bias during inference. Experiments on four datasets, including controlled comparisons with Mamba-based classifiers, comparisons between PCA and original-band inputs, head/medium/tail group evaluations, and sensitivity analyses under varying imbalance ratios, demonstrate competitive performance and improved tail-class reliability. These results provide complementary evidence for the effectiveness of the SPARC-Net for long-tailed HSI classification. © 2008-2012 IEEE.

ROBOTICS AND AUTONOMOUS SYSTEMS
Abstract
Robotic bin-picking is a critical operation in modern industry, which is characterised by the detection, selection, and placement of items from a disordered and cluttered environment, which can be boundary limited or not, e.g. bins, boxes or containers. In this context, perception systems are employed to localise, detect and estimate grasping points. Despite the considerable progress made, from analytical approaches to recent deep learning methods, challenges still remain. This is evidenced by the growing innovation proposing distinct solutions. This paper aims to review perception methodologies developed since 2009, providing detailed descriptions and discussions of their implementation. Additionally, it presents an extensive study, detailing each work, along with a comprehensive overview of the advancements in bin-picking perception.

Abstract
Manual selection of real estate properties can pose considerable challenges for agents since it needs a careful balance of various factors to satisfy client requirements while also manoeuvring through the complexities of the market. Although automated valuation models are widely used to estimate property market values, they are not designed to support property recommendation tasks. To address this gap, filteringbased recommendation methods have been explored, including collaborative and content-based approaches. However, these methods face several limitations in the real estate domain. This paper proposes a recommendation methodology designed to identify houses that closely resemble a given property, allowing agents to select the best matches based on geographical and physical characteristics. To assess the performance of the proposed methodology, we employ a range of evaluation metrics that measure different aspects of the model's effectiveness in ranking and recommending relevant items. The findings suggest that, while geographic features may slightly influence ranking behaviour, the model is capable of producing diverse and relevant recommendations consistently.
