Haqq-Misra and Kopparapu analyse limits on inferring motion from 112 released sensor-video records. Angular motion depends on range, viewing geometry and platform motion. A transverse-speed bound does not establish total speed or identify every object.

Knuth and colleagues explain Bayesian evidence, prior-sensitive model comparison and approximate estimation. Their examples show how assumptions, dependent observations and numerical uncertainty affect apparent model winners. The paper provides methods context for evaluating claims; its sensor example overlaps an earlier study and supplies no independent UAP observations.

Davis proposes wormhole propulsion while rejecting a claimed magnetic wormhole solution as a hypercylinder. He cites private technical communications, acknowledges colleagues and reports partial NIDS support. The proposed physics and contacts do not establish an achieved device, classified UAP briefing or recovered hardware.

Keto and Watters test satellite timing on two balloon examples and a snowy scene where ground alignment fails. Apparent fast motion is parallax. Timing is inferred under fixed-rate and negligible-motion assumptions, with incomplete independent ground truth and uncertainty.
Amir Siraj, Abraham Loeb. arxiv.org. September 12, 2019.
Siraj and Loeb argue that a roughly kilometer-scale Borisov nucleus better matches an assumed ordinary Oort-cloud mass budget. An eight-kilometer alternative produces substantial tension with that benchmark, without independently disproving the larger size. Their figure uses four points for three object families, including two alternative Borisov radii. Sparse Poisson bounds do not capture every observing or population uncertainty. This is a conditional argument using reported observations, not a new measurement campaign or artificial-origin finding.

Siraj and Loeb infer an interstellar meteor trajectory from catalogue inputs and an assumed error model. The paper attributes uncertainty information to Heavner and quotes a reported DoD statement, with Worden, Daniels, Shaw, Mozer, an anonymous analyst and Hurd credited for distinct clarification roles. Original correspondence and classified data were not received. Conditional confidence, ordinary bound comparators, population assumptions and mass-budget tension remain. Government review does not establish researcher classified access, artificial origin or recovered material.

A calibrated light-sensor model helps a robot locate a known white circle with fewer reported measurements. The task uses fixed lighting, distance and prior shape assumptions. Supplied uncertainty values are missing, and native equation, count and date discrepancies remain unresolved. These results do not establish general object recognition or UAP performance.
