D4-branes wrapped on topological disks from matter-coupled F(4) gauged supergravity
Patharadanai Nuchino, Parinya Karndumri
We study a number of supersymmetric solutions with being a topological disk with non-trivial holonomy on the boundary or a ``half-spindle'' from matter-c…
Unified Agent: Managing Interactions across Devices
Xinshuang Liu, Runfa Blark Li, Shaoxiu Wei +2
As capabilities rapidly increase, AI agents can move from running inside one app to acting across a user's devices over time. Yet existing agent systems still fall short in this sc…
GaussianSelector: Lightweight Human-Guided Object Selection in 3D Gaussian Splatting with Graph Optimization
Baihan Yang, Tiexin Li, Yuheng Liu +4
Selecting a complete 3D object from a reconstructed scene with minimal user effort is essential for practical scene editing and embodied interaction. Existing 3DGS-based methods ei…
Score-Regularized Joint Sampling with Importance Weights for Flow Matching
Xinshuang Liu, Runfa Blark Li, Shaoxiu Wei +1
Flow matching models effectively represent complex distributions, yet estimating expectations of functions of their outputs remains challenging under limited sampling budgets. Inde…
DexFuture: Hierarchical Future-State Visuomotor Targeting for Bimanual Dexterous Tool Use
Runfa Blark Li, Kuang-Ting Tu, Nikola Raicevic +6
Bimanual dexterous tool use remains challenging for robots due to high-dimensional hand configurations and complex hand-tool-object dynamics and contact. Most existing control poli…
PhysGraph: Physically-Grounded Graph-Transformer Policies for Bimanual Dexterous Hand-Tool-Object Manipulation
Runfa Blark Li, David Kim, Xinshuang Liu +7
Bimanual dexterous manipulation for tool use remains a formidable challenge in robotics due to the high-dimensional state space and complicated contact dynamics. Existing methods n…
