From the introduction:

We examine three major parameters:

1) the likelihood rate of abiogenesis ({\lambda}A);

2) evolutionary timescales (Tevo); and

3) probability of self-annihilation of complex life (Pann)

To my understanding:

1) Unknown.

2) Unknown outside earth.

3) Unknown.

Given the title and the problems above, I didn't read beyond the introduction as time is limited.

It sounds like an updating of the Drake equation without addressing the fundamental problems with that as an estimation tool rather than a more modest method for informing interesting speculation.
