The first question is chock-full of technical jargon and it is about a fairly esoteric subject. It is not likely that there are many people who can adequately answer this question without first putting in copious effort to research it completely. Given that, it's unsurprising that there are no good answers because not many are going to look at it and find it worthwhile to put in such large amounts of effort for an old question. The answer isn't likely to be helpful anymore and the reward in reputation isn't likely to be worth the time.
As to the second question, I honestly can't even explain why it was highly voted in the first place. From the look of it, it seems to be saying "I was reading some literature and didn't understand something. I tried doing that thing myself but don't know if I did it right. Here is what I did, did I get something wrong somewhere? What am I missing?" The only difference between this question and the run-of-the-mill questions we close every day is that this isn't basic physics from a first-year textbook. To me, this still looks like a check-my-work question that doesn't seem to be about any concepts and wouldn't really be useful to others. So again, I'm not sure why it was upvoted and I don't personally care why nor that it hasn't been answered. Probably because nobody wanted to check the OP's work.
