Tim,
 
Very good article. I got the article I told you about (attached).
 
Barton, G., "On the Finite-Temperature Quantum Electrodynamics of Gravitational Acceleration", 
Physical Review D, Vol. 40, No. 12, 1989, pp. 4096-4099
 
This shows, that further analysis from Donogue & Holstein's approach leads to no deviation in 
the equivalence principle (as claimed and used by De Aquino). So the theory on which he bases 
his research is wrong.
 
Moreover, in his simplified approach using Hamiltonian etc., he also does some basic mistakes.
 
Please revise your quote based on this paper that I pointed out. The sentence about Gravity 
Probe B is fine.
 
Greetings,
 
Martin.
