I read the summary thoroughly and scanned the rest, and I don’t think the paper supports the grandparent comment.
The paper says you can produce enough vitamin d to maintain healthy levels from a specific amount of sunlight per day, depending on latitude and skin color.
The original comment suggests that there’s some (very short!) limit beyond which the body is unable to produce more vitamin d, which is very different. I’d be very curious to see sources for that.
UVB synthesizes cholecalciferol (vitamin D3) in the skin, which the liver converts into calcifediol (what blood tests usually measure), which the kidneys convert to calcitriol (the active hormone). Wiki claims the kidneys have a negative feedback loop, converting excess calcifediol into inactive 24,25-dihydroxycholecalciferol. I wish I had better sources (for my vitamin D pdf folder).
The same wiki article says there is a limit to the capacity of synthesis by UVB due to the quantity of reagent 7-dehydrocholesterol produced in the skin, but I don't know the math on what amount of exposure would be required to hit that limit - presumably it (or something like it) is covered in the article above.
I’m a normal weight, and get asked the same question. More importantly, I can tell them, “I have a regular cycle” and they WILL NOT take that as an answer. I HAVE to give them a date, and they will ask me to make one up if I can’t remember or want to decline giving them that information.
Particularly given the alarming stories of people being prosecuted for having miscarriages, it feels ridiculous.
If anything I hope more automated diagnostics and triage could help women and POC get better care, but only if there’s safeguards against prejudice. There’s studies showing different rates of pain management across races and sexes, for example. A broken bone is a broken bone, regardless of sex or race.
The system doesn't know that you're a smart person who will only say "I have a regular cycle" when you've had something that could reasonably be called a regular cycle. A lot of patients are stupid, and requiring a quantitative answer eliminates one source of stupidity. Yeah, this particular doctor knows you're smart, but I hope you can see what disasters might result if the procedure said "the doctor may skip this step if the patient is smart".
It's the same reason why the doctor will take your temperature, instead of accepting your word that you took your own temperature and it is normal.
> Particularly given the alarming stories of people being prosecuted for having miscarriages
You need to delete your social media accounts and change where you're getting your news from. Nobody is "being prosecuted for having miscarriages". A few people have been investigated for drug abuse during pregnancy which led to the baby's death, which sensationalist news stories twisted into attention-grabbing headlines.
A doctor asking about cycle is just a core piece of diagnostic data like taking blood pressure and temperature, not some conspiracy to harm you.
I’ve observed that animals are pretty good at reading body language and can tell when they’re actually being seen by, rather than just sharing space with, a human.
The seeds have natural coagulants that clump particles enough to be mechanically filtered / settled.
I wonder what happens to the resulting sludge with concentrated plastics? That’s an issue with bioremediation for lead in soils. The plant materials needs to be removed from the site order to make any difference. If we’re currently using alum in the same way, there must be a strategy for cleaning it or disposing of it safely.
Sounds like this might not be a scalable solution, but great for diy setups and rural communities without access to industrial options.
> Candidates glean info about their possible teammates and work experience from the interviewer
From everything I’ve heard about working in Amazon warehouses, getting interviewed by a faceless robot is probably giving an accurate impression of the work culture. Even for a seasonal job it feels disrespectful to the candidates.
Okay. Let's say we find out tomorrow that Spirited Away was animated via generative AI. Unbeknownst to everyone, Ghibli has a top-secret AI division which—thanks to some key lucky breakthroughs—is many decades ahead of everyone else and has been for a long time. The animators are a front to hide the truth; Miyazaki's anti-AI declarations were pure jealousy.
You miss something critical here. For that to happen that GenAI would have had to be trained on another "Ghibli".
So your question isn't whether Ghibli had an AI, but whether Ghibli had a whole time traveling machine with it.
Your question feels like asking whether Einstein, Plato, etc. were secretly time travelers and copied someone else's style.
Something that is a general problem with all GenAI is that they copy and imitate. And just like with code being messy and dumb you'll find that Stable Diffusion in pieces of art does stupid and dumb stuff. Things it wasn't trained on. You can most prominently see that in big detailed fantasy (as in not just a photo) pictures, and looking at details. While the overall thing "looks cool" you don't get the details that artists do and you notice a lot of silly, dumb and what for a human author would be a "strange thing to invest time in and still do so badly" kind of situation.
I'd argue if we had AI in the sense that it had actually understood things and it could actually show creativity, etc. the story might be different, but as of today it is unknown whether that's possible. It would make sense, just like alien life would make a lot of sense. But for both actually thinking systems and alien life we have no clue how close we are to seeing one.
Every time someone takes an unbiased look at it (and there are many papers) it is shown that there is no understanding of anything, which to be fair is far from surprising given what the "training" (which is just a term that is an allegory and something that is kinda simulated, but also not really).
There might very well be hard and pretty obvious limitations, such as to feel and express like a human you need to be a human or provide away to simulate that and if you look at biology, anatomy, medicine, etc. you'll soon realize that even if we had technical means to do so we simply don't know most things yet, otherwise we could likely make Alzheimer, artificial brains, etc.
The topic then might be aside from all the ethical parts (when does something have human rights), whether a superhuman as all the futurists believe there will be even be able to create something of value to a regular human or are the experiences just too different. It can already be hard to get anything out of art you cannot relate to other than general analytical interest. However on that side of things Spirited Away already might be on the "little value" side.
This isn't to defend human creation per se, but to counter often completely off understanding of what GenAI is and does.
One final comparison: We already have huge amounts of people capable of reproducing Gibli and other art. Their work might be devalued (even though I'd assume some art their own stuff into their work).
People don't buy a Picasso, because they can't find a copy or a print that even has added benefits such as requiring as much care, being cheaper. Einstein isn't unimportant today, because you learn about his work in school or on Wikipedia.
But your question is like asking whether Einstein's work would be without value, if he secretly had Wikipedia.
> You miss something critical here. For that to happen that GenAI would have had to be trained on another "Ghibli".
Eh, maybe it got trained on Nausicaä, and then a lot of prompting and manual touch up work was used to adapt the style to what we now know as Spirited Away. Or maybe that animation department wasn't completely for show and they did draw some reference frames, but the AI figured out everything in between.
I don't really want to get into a discussion about the theoretical limits of AI, because I don't know what they are and I don't think anyone does. But if "the process is important for art," what happens if the creator lies about the process? If you initially experience the art without knowing about the lie, does learning the truth retroactively erase your previous experience? How does that make sense?
It has always seemed more logical to me that the final piece ought to be all that matters when evaluating art, and any details you know about the creator or process should be ignored to the greatest extent possible. That's difficult to do in many cases, but it can be a goal. I'm also aware that lots of people disagree with me on this.
Spirited Away is an intricate expression of Miyazaki's ethics as formed by his unique lived experience and nostalgia for classical Japanese culture, as well as a criticism of Western capitalist excess filtered through Shinto philosophy.
There is literally no universe in which a generative AI creates a work of art of that magnitude. You can get "make this meme is the style of Ghibli" from an AI and it can imitate the most facile properties of the style but that still requires the style to imitate. AI is never going to generate the genius of Hayao Miyazaki from first principles, that isn't even possible.
the process is not important for art, although it might have value for people. art is a subjective experience, one that comes to life in the obeserver.
