Halpern et al., International Journal of Modern Physics B, Volume: 24, Issue: 10(2010) pp. 1309-1332 DOI: 10.1142/S021797921005555X. I’m pretty sure that has been blogged elsewhere, but call me Mr Sleepy. Anyway, a useful ref for those interested, and congrats to all involved for their patience with fools.
