Lightweight design of the skeletal structure is a critical challenge in the development of Blended-Wing-Body Underwater Gliders (BWBUGs). However, existing studies often rely on empirically derived configurations for parameter optimization, which limits the potential to fully exploit structural performance. To address this issue, this paper proposes a design approach for BWBUG skeletal structures that integrates topology optim...

Understanding the distribution pattern and its drivers of species is crucial for developing effective and sustainable management strategies. Amphioctopus fangsiao is the octopus of significant commercial and ecological value along the coast of China, with multiple distinct populations. However, research on their ecological dynamics remains limited and requires further investigation. Here, ensemble models were constructed to ex...
