  1. Surg-InvNeRF: Invertible NeRF for 3D tracking and reconstruction in surgical vision

    cs.CV 2025-08 unverdicted novelty 6.0 of 10

    An invertible-NeRF test-time optimization approach tracks points in 2D and 3D across surgical videos, reporting roughly 50% higher average precision than prior optimization-based 2D trackers.

  2. Foundational Structure of Local Amplitudes in Quantum Gravity

    gr-qc 2025-08 conditional novelty 6.0 of 10

    Local amplitudes for causal diamonds can be constructed from null-slab boundary states, projectors, and vacuum intertwiners, with Ward identities and charge conservation as consequences.
