These press releases correspond to a series of papers now in press in the Planetary and Space Sciences journal. There are a number of Huygens-related papers there, haven't quite perused them all, yet.

Are these the same papers noted in Huygens post 408?

Probably. Just access http://www.sciencedirect.com/science?_ob=PublicationURL&_tockey=%23TOC%235823%239999%23999999999%2399999%23FLA%23&_cdi=5823&_pubType=J&view=c&_auth=y&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=9d7727cc6430820045da2d0b24d8aee7, and scroll down. Most of the papers in the upcoming special listed are posted.

Fernando Simões, from the PWA team and author of one of those papers, wrote some words about the Titan's radio wave for http://spaceurope.blogspot.com/2007/06/regarding-latest-findings-about-another.html.
He presents three alternatives:
"There are three major scenarios for explaining the origin of this signal: electronics problem - malfunction of PWA or interference with other instruments; mechanical vibrations - interference with the booms that hold the electrodes of the dipole antenna, the parachutes or the Huygens craft; natural signal – resonance within the cavity of Titan."

It is good to be back...

The electron density plot is cut off at 45km altitude...what happened after that?

from the paper:

QUOTE

The density profile (Fig. 14) is limited intentionally, downwards, to the altitude of 40 km because of the lack of accuracy when the conductivity decreases (a consequence of the calibration with respect to low altitude conductivity measurements).

(conductivity steadily decreases below 40 km)
