WAPR: A Foundation Model for Wide-Angle Refinement in Unseen Object Pose Estimation
Yulin Wang, Mengting Hu, Hongli Li +2
Real-world applications require 6D pose estimation to be accurate, fast, and scalable to unseen objects. This paper introduces WAPR, a zero-shot wide-angle pose refinement model th…
Primordial Magnetogenesis from Killing Vector Fields
Nagabhushana Prabhu
Papapetrou showed that the covariant derivative of a Killing vector field satisfies Maxwell's equations in vacuum. We extend Papapetrou's result to show that the covariant derivati…
Static Solitons in an Expanding Universe
Nagabhushana Prabhu
We show, analytically, that a static sine-Gordon soliton cannot exist in 1 + 1 non-dynamical de Sitter spacetime if , where is the mass parameter of the sine-G…
CultureMINE: Datasets and Methods for Improving the Cultural Capabilities of NLP Systems
Tania Chakraborty, Eylon Caplan, Zhaoqing Wu +4
In recent years, there has been a surge of interest in Cultural NLP, with substantial efforts to create globally inclusive NLP systems. The rapid growth of literature in this field…
Spatiotemporal Flux Probing for Single-Photon Videography
Jerry Yan, Matteo Forlivesi, Bowen Tan +3
We address the problem of recovering high-speed videos from dynamic scenes under extreme photon sparsity. Existing methods rely on aggregating photon detections in local spatiotemp…
Formation of Ryugu's parent planetesimal beyond the CO snow line from small pebbles: insights from thermal evolution modeling
Sota Arakawa, Hidenori Genda, Noriyuki Kawasaki +3
Astronomical observations of planet-forming circumstellar disks indicate that planetesimals form from 0.1-mm- to 1-cm-sized dust aggregates, commonly called ``pebbles.'' When such…
