Aura: Consistent Multi-Subject Video Generation via VLM-Grounded Semantic Alignment

Zixiang Zhou, Zhentao Yu, Yifeng Ma, Hongmei Wang, Wenqing Yu, Cong Wang, et al.

Subject-driven and multi-element video generation are central to controllable video synthesis, but existing methods still struggle to preserve identity consistency and model complex relationships among multiple subjects. In this paper, we propose Aura, a unified framework for hig…

Data-Driven Modeling and Control for Tethered Space Systems with Koopman-Informed Graphs

Ao Jin, Yifeng Ma, Panfeng Huang, Fan Zhang

Modeling tethered space systems is critical for advanced orbital operations. Flexible components such as tethers and space nets are integral to these systems but present significant control challenges due to their high dimensional, strongly coupled, and nonlinear dynamics. While…
