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.
