> vaccine which is tested exclusively on young men
is COMPLETELY wrong.
1. The trials have been performed on both men and women
2. Age groups <65 AND >= 65
3. Also included chronically ill
From Moderna:
> As of today, the COVE study includes more than 7,000 Americans over the age of 65. It also includes more than 5,000 Americans who are under the age of 65 but have high-risk chronic diseases that put them at increased risk of severe COVID-19, such as diabetes, severe obesity and cardiac disease. These medically high-risk groups represent 42% of the total participants in the Phase 3 COVE study.

The blog post is a 3,500 word advertisement to Amazon affiliation links. A selection of "helpful" advice given in the post:
- How to chop food? "Just search them on YouTube"
- "When you are first learning to cook I recommend avoiding complex recipes"
- "Get cooking"
Finally: "The goal of this post is [..] to provide fairly comprehensive [..] roadmap for going from a cooking noob to solid home chef." Sorry. This is not it.
[^] Alternatively, the title might be interpreted to mean "Cooking for founders [who are visiting you]". This is also not the case.
It seems about 87%-53% = 34% of Americans fly once a year.

> One-third (33.9%) of the Spanish population may be at risk for Vitamin D deficiency.
So that doesn't explain the >80% from TFA.
So doesn't explain the whole observed effect
Edit: also the study was in Spain, not USA
Also because he wasn't referring to Black people but rather to young people. You have to read your own link better.
From Snopes: " What's True
While speaking in the Senate in 1993 in favor of the Violent Crime Control and Law Enforcement Act, Biden referred to young people who have become criminals as "predators."
What's False
Biden did not use the term "super-predator," nor did he specifically refer to Black people. It was Hillary Clinton who, while speaking about the Violent Crime Control and Law Enforcement Act a few years later, referred to young gang members as "super-predators." "
"The trained network was able to differentiate positive and negative IBV samples with high accuracy (91.4%), sensitivity (91.9%) and specificity (90.9%) (Fig.2G). Of note, these probabilities refer to single virus particles in the sample and not the whole sample; the probability of correctly identifying a sample with hundreds or thousands of IBV virus particles will therefore approach 100%. "
But then when the actual lab tests are performed:
"The trained network was able to distinguish between virus-positive and virus-negative samples with excellent accuracy, distinguishing between SARS-CoV-2-positive and negative BBXs with an accuracy of ~70% (Fig.3A)".
An accuracy of 70% is totally useless for such tests if widely applied, right? What am I missing here?

So could any other type of antenna, basically. It doesn't have to be a dipole, though.

Based on the images, that's not what happens here

That is absolute horseshit. Large dipole arrays will suffer from high mutual coupling which could drastically reduce performance (depending on design choices). Different antenna types might be more suitable for different scenarios, but that's why I would like EmRod to explain their choices.
Furthermore, a rectenna gives you DC power out, but why would EmRod want this?
3 meter diameter panels @ 5 GHz gives a diffraction-limited beamwidth (FWHM) of lambda/D = (3e8/5e9)/3 * 180/pi = 1.5 degrees
0.75 degrees (1.5 degrees is the full angle) gives tan(0.75×pi/180)×(2×40) = 1 meter panels at receive (40 meter from transmit) to intercept the FWHM power. So a 3 meter receive panel will intercept more than the FWHM --> 70% seems like a realistic number for the percentage of power intercepted.
I have crunched the numbers again on a new envelope, and with some realistic Tx/Rx panel size (3 meters) at 5 GHz, I see how you may end up with 70% efficiency assuming diffraction limited panels but also with 100% efficiency of the electronics.
Since I have the idea that you are part of Emrod, I would like to ask you why you opted for rectennas at receive and not some other antenna tech? Is it simply the integration between antenna and rectifier (smaller footprint?) or are there more reasons?
If you are wondering why D614A is not mentioned in the Nature article: the preprint has been out for 2 days (Nature published yesterday) and this information is only based on a single pre-print, not a peer-reviewed scientific article. I don't think saying "who cares about obscure -stans" is fair towards the author of this article.
