This study addresses limitations in traditional Problem-Based Learning (PBL) for object-oriented programming (OOP) education, which focuses on isolated programming knowledge and fails to personalize learning. We propose an AI-driven framework where students collaborate with Agentic AI to tackle authentic challenges. The AI assists by decomposing projects into Minimum Viable Solutions (MVS), co-designing ...

We introduce Textbook2KG for building knowledge graphs from lengthy textbooks using large language models (LLMs) and smart prompts. Our framework uses a step-by-step approach: splitting texts, extracting key facts, and connecting concepts through reasoning. Tested on three real textbooks, it achieved 85.5% accuracy in direct fact extraction but 65% for inferred links, showing where LLMs shine and where ...

Large language models (LLMs) demonstrate strong general language capabilities but struggle with historical question answering due to fragmented reasoning and imprecise knowledge retrieval. To address these limitations, this study integrates finetuning, prompt engineering, and knowledge graph augmentation to enhance reasoning accuracy and factual consistency in complex historical queries. We fine-tune ...

This paper introduces a fresh, window-driven approach to building stock portfolios, emphasizing flexibility and precision in navigating complex financial markets. At its core is a hierarchical meta-ensemble model that powers stock price forecasting by combining multiple predictive models, like LSTM and XGBoost, to capture market trends effectively. Paired with a dynamic time window mechanism, the model ...

单链 DNA（single-stranded DNA，ssDNA）适配体是通过体外配体指数富集系统进化筛选获得的较短的单链脱氧核糖核苷酸序列。它们能够通过构象变化实现与靶标高亲和力和特异性结合，具有制备简单、成本低、稳定性高、易于修饰和免疫原性低等优点，因此被称为“化学抗体”。ssDNA 适配体已在食品安全检测领域显示出巨大潜力。作者综述了基于细胞指数富集配体系统进化（systematic evolution of ligands by exponential enrichment，SELEX）...
