This is interesting data. I want to see Vitamin D status included in a large population study like this because I've been following two smaller studies covering about a thousand cases total that shows Vitamin D deficiency has a risk ratio of 10 to 20 (more even than being age 80+ in the above study). The studies:
Table 1 in each of those papers show Vitamin D status vs Outcomes. The correlation between Vitamin D status, where Normal is >30 ng/ml (or 75 nmol/L), and death rates is stark.
From [1] (which had n=780 cases) here is the punchline: "98.9% of Vitamin D deficient cases died while only 1.1% of them were active cases. 87.8% of Vitamin D insufficient cases died while only 12.2% of them were active cases. Only 4.1% of cases with normal Vitamin D levels died while 95.9% of them were active cases."
From [2] (which had n=212 cases) here is the punchline: "Of the 212 (100.0%) cases of Covid-2019, 49 (23.1%) were identified mild, 59 (27.8%) were ordinary, 56 (26.4%) were severe, and 48 (22.6%) were critical (Table 1). Mean serum 25(OH)D level was 23.8 ng/ml. Serum 25(OH)D level of cases with mild outcome was 31.2 ng/ml, 27.4 ng/ml for ordinary, 21.2 ng/ml for severe, and 17.1 ng/ml for critical."
Note: the classification for outcomes was "(1) mild – mild clinical features without pneumonia diagnosis, (2) ordinary – confirmed pneumonia in chest computer tomography with fever and other respiratory symptoms, (3) severe – hypoxia (at most 93% oxygen saturation) and respiratory distress or abnormal blood gas analysis results (PaCO2 >50 mm Hg or PaO2 < 0 mm Hg), and (4) critical – respiratory failure requiring intensive case monitoring."
I want to see a dozen more studies like [1] and [2] to see if this holds up to replication with larger populations.

The show notes for the parent video are quite comprehensive with links to references. The summary above leaves out the detailed discussion of the interplay between Vitamin D, the renin-angiotensin-system, the ACE2 receptor, and SARS-CoV-2:

Here's a description of a "press-pulse" protocol that includes fasting, calorie restriction, and ketogenic diet scenarios (main goal seems to be to limit glucose intake as part of the treatment as part of an effort at stressing the energy systems of the cancer cells to cause cell death):

Check the references for some other papers on fasting and chemotherapy. Also, here's a related human case study: https://www.ncbi.nlm.nih.gov/pubmed/29651419
While lacking in lots of built-in UI widgets, I use Cinder like a UI library. https://libcinder.org/ Perhaps "graphics library" would be a better descriptor and explains why I didn't find it on the list. But with mouse/touch, images, audio, video, etc. support, "graphics library" seems too narrow of a description. Maybe it's better to think of as a GUI library without a lot of commitments to the usual set of GUI widgets.
I suppose a bit more context would be explanatory. My real interest is not the free-space performance of the antenna, but the eventual installed performance. In the video describing the setup he says "I talked with a couple of engineers, and some other guys, and we've come to the conclusion that if I put 100 watts into it, it might radiate a milliwatt. And not all that well." I'm not sure if they were thinking of it as a magnetic loop antenna the way you described or coming up with the numbers some other way. But then at the end mentions, "I'm gonna set it on the top part of that air conditioner and put it right in the window." How much of his success is a result of sticking the antenna on what may be effectively a (admittedly electrically small compared to 20m) metal box? That's what I think is interesting to simulate.
Can anyone simulate this light bulb setup in HFSS or another antenna simulation software? I'm always on the lookout for comparisons on weird cases like this for the simulation code I've written. If I can find material property data on custard as easily as for tungsten (watch the temperature dependence!) I might give that a shot next.
