Novel QSAR and QSPR descriptors?

For the past few weeks I have been working on a review article, which will contain a section with new QSAR/QSPR descriptors published in the period 2000-now. Here are a few:

2001: oxygen paths of length 3 10.1021/ci000116e
2002: a molecular shape descriptor 10.1021/ci000100o
2003: molecular signature 10.1021/ci020345w
2004: 4D-fingerprint 10.1021/ci049898s
2005: summed NMR shift difference 10.1021/ci049643e

If you know additional new descriptors, or feel like discussion one or more of the above, please leave a comment.
