Why not make an example of him? What are they trying to hide?
Might be some weird laws.
What happened to the presumption of innocence, AKA "innocent until proven guilty"? The suspect hasn't been tried or convicted yet..
The paper you linked to says N95 are effective down to 2nm. That's over 100 times smaller that the 0.3 microns you mentioned. To quote the paper:
In addition, the increase in filtration efficiency due to electrostatic attraction is most significant for 2 to 100 nm particles illustrating that filtration efficiency depends on the particle size and air flow.
and
Large particles (5 ~ 10 [micro]m in diameter) and small particles (2 ~ 1000 nm in diameter) were attached on the outer, filter, and inner layers (Figure S5). Hence, mechanical filtration allowed N95 respirators to retain their filtration efficiencies despite a loss of dipole charge during decontamination.
It's both. 18 million smart electricity meters, and 13 million smart gas meters.
No, the 95% efficiency is measured at the "most penetrating particle size", or MPPS, which is the particle size the masks work least well with. N95 masks filter both smaller and larger particles more efficiently than that.
That paper says: "In conclusion, a loss of electrostatic charge does not directly correlate to decreased performance of either respirator [N95 or KN95]"
I was going by this paper: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7961645/ which says:
"Electrostatic filtration was responsible for approximately 1/3 of the filtration efficiency for the N95 respirators tested."
I'm out of my depth here - I don't know who is right.
Sometimes, sometimes not. You can have a full engineering model, a bench model (same h/w componants, but layed out on a bench), a simulation running using the same physical processor, or a complete software simulation. And probably other variations.
Modifing the on-board spacecraft software is often done to cope with hardware that's either failing, or behaving differently than expected. It's not just s/w bug fixing. That kind of fix might be easier to test in a software simulation, were you have full control over the virtual hardware, and you can make it behave how you want.
N95 masks have an electret filtration layer, which effectively has a permanent electrostatic charge. It's not a just a mechanical filter like a sieve, they actively attract submicrometer-sized aerosol particles to the mask fibres. This is also why you should be wary of trying to clean masks for re-use - soaps can significantly degrade the electret charge.
I tried using Spotify a few years ago. I asked it to play something and it played me that then instead of continuing to play the specific band I had asked for it went all loopy and played me something else that had a similar name. So I considered it broken.
Did they fix that? I assumed it was a feature you had to pay for, to actually listen to what you want and not random stuff that you could simply listen to over FM!
My understanding is that the music licensing costs for internet radio streaming are lower than on-demand streaming, and that the Spotify free service counts as internet radio, which is why they do it like that,
The fact that the receiver pays most or all the costs for mobile phone calls in the US doesn't help (I think - is that still true?). In Europe the caller always pays, so robocalling is a lot less cost effective.
Pretty much everywhere the frequency is deliberately adjusted to keep such clocks accurate.
I've sideloaded an app on an old Android device because the version in the play store only supported Android 10+. There are several sites that offer old versions of apps for download, I just wish I had some reliable way of knowing which ones can be trusted (if any).
I've also sideloaded an app that was only available in the US play store, for no good reason I could fathom.
It seems that a lot of people aren't familiar with some of the useful search modifiers available in Google. For example, you could add a "site:slashdot.com" to limit your search to the specified URL. Haven't needed this in a while so I can't confirm that it still works, but it used to.
It does. There is always https://www.google.com/advance... for thoese people that don't know the search modifiers .
It reminded my of Rachel Riley's dress from Cats does Countdown
6 GHz is about 2 light-inches. That is, light travels about 2 inches in one clock cycle.
Not just VMS, the ISO-9660 data CD standard also has file version numbers. Dunno if anyone ever used them.
