[Topic-models] derivation of updates for variance parameters in variational Kalman filtering

Is there any derivation for the updates of the variational "variance
parameters" (the \nu^hat_t's) for the following papers?
1. Dynamic topic model --
2. Continuous time dynamic topic model --
I'm trying to implement these models myself and having a hard time deriving
some of the updates. Any help will be much appreciated.
