Peer-reviewed MDPI Entropy paper (21(10):939, doi:10.3390/e21100939; pub. 25 Sep 2019) estimating lower-bound accelerations for several UAP encounters, centered on the 2004 Nimitz case. A conference version appeared at the 39th MaxEnt Workshop, Garching, 2019.

Lead-authored by Kevin H. Knuth (Dept. of Physics, University at Albany / SUNY) with Robert M. Powell and Peter A. Reali (SCU). Method: assume constant acceleration for half the maneuver and equal deceleration for the second half to obtain conservative lower bounds, with deliberately liberal uncertainties. Result: estimated lower-bound accelerations from ~100 g to thousands of g with no air disturbance, sonic boom, or commensurate heat. The paper (as a published, methodologically explicit artifact) is documented; its physical estimates and 'far more advanced' conclusion are the claim.
