"Up to 50% of patients with cannabis-related psychotic symptoms presenting to the ED requiring hospitalization will go on to develop schizophrenia. "
https://www.frontiersin.org/articles/10.3389/fpsyt.2021.640222/full
"Cannabis is involved in approximately 50% of psychosis, schizophrenia, and schizophreniform psychosis cases"
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3927252/
"In one recent study that followed nearly 2,000 teenagers as they became young adults, young people who smoked marijuana at least five times were twice as likely to have developed psychosis over the next 10 years as those who didn’t smoke pot."
"One of the best-known studies followed nearly 50,000 young Swedish soldiers for 15 years. Those who had smoked marijuana at least once were more than twice as likely to develop schizophrenia as those who had never smoked pot. The heaviest users (who said they used marijuana more than 50 times) were 6x as likely to develop schizophrenia as the nonsmokers."

"1/5th of cases of schizophrenia among young males might be prevented by averting [Cannabis Use Disorder]"

Daily weed use was associated with increased odds of psychotic disorder compared with never users, increasing to nearly 5x increased odds for daily use of high-potency types of cannabis. The PAFs calculated indicated that if high-potency cannabis were no longer available, 12% of cases of first-episode psychosis could be prevented across the 11 sites, rising to 30% in London and 50% in Amsterdam

This is a good take honestly. I probably should never use cannabis, not smoked or eaten even, since I have a direct family member affected with schizophrenia and psychotic symptoms. But I do think people have the right to use it with moderation and for health purposes, maybe a bit recreational too. It does worry me how normalized it's becoming, and how easy to abuse it is. Same with alcohol.

/x/ here, I wouldn't say that cannabis is a material causation for some type of schizophrenic chemical reaction but compared to other psychedelics it can actually be very dangerous and I don't think people talk about it enough. Especially edibles.
For spiritually receptive people it opens up the human mind to multiple spirit realms all at once, if a door closes another opens, not specific spirits or realms but an excess of them all sampling through the subject. With that in mind it can become overwhelming and chaotic very quickly, and unlike most other psychedelics weed seems to connect your sense of self to your body even tighter than you are normally. Add weed induced paranoia and dilating blood vessels with a harder heart beat and something difficult is bound to happen to the uninitiated with his mind now opened. Those who do not close the doors afterwards, ignore needed metaphysical work and let the fear consume them are in danger to fall into "schizophrenic" thinking.
The spiritually unreceptive don't know what they are recommending when they say it's just a relaxing substance.

Let's say you wanted to create a formula without using google, all by yourself that describes the grey area between those circles in terms of the three variables: the radii of the circles and distance between their centers. No googling allowed, just using pen and paper and calculator.

How hard would that be?

Question:
Say I have some (tensorflow) neural network. Given some linspaced values x, how can I make the initial weights/state of the neural network mimic some function f(x)?
I suppose one way to do it would be to train a network to mimic f(x), and then use those weights as the initial weights of the real network, but surely there's a better way to do this?
Basically what I want is for NN(x) in its initial state to look close to f(x), if plotted for some continous variable x. Like an ansatz, if you will

>The bummer is the implicitly packed into ranking. Suppose we were to compare correlation between guns and deaths. It seems that there are many different ways to rank cities or counties and we could tease out preferred results by ranking across arbitrary parameters.

Putting aside your /pol tier question, That isn't even close to how this statistic works.

You are not ranking cities. You are ranking the ordered pair of (number of guns in an area, gun deaths in an area), BY the order of the number of guns in an area, so as to create a ordered ranking of the gun deaths by area to see if they are out of order, and by how much. If the ranks of the gun deaths were perfectly in order in both monotonicity and difference, then the new function would return a 1. If they are out of order, the new function would return some value from zero to one that is closer to zero.

So if you are asking if you could pick samples or populations to fit your prior conclusions, that is true of every statistical measure, but the order of the rank of Y is set by ordering the X, which is monotonic increasing.

I was sent a video of someone who supposedly built a pyrolysis process that used microwaves to heat the plastic. Now I know how pyrolysis works, but would the microwaves actually be able to heat the plastic? As far as I understand the only reason microwaves work on water is because of its polarity, and plastics are (essentially) non-polar.
>>
>>16162917
Microwaves definitely work on non- and semi-polar molecules. Many plastics also have significant amount of C-O bonds, so are far from pure grease.
From what I've read, fats can reach some pretty insane temperatures too, often enough to fry bacon and scorch the food if they dry out (try microwaving a slice of sausage or pepperoni for too long, it gets toasty)

>then you've seen real autism.
As opposed to the not-real autism that would pose problems to your le vaccine-autism theory? Isn't this kind of self-defeating to have your hypothesis phrased in such a way as to only allow for the one possible outcome while ignoring all the other presentations even if they boil down to the exact same thing
>but if you've seen the retards who reach into toilet bowls to fish out their own turds and throw them around everywhere
Yes, but why do we pretend that this "autism" and asperger "autism" is one and the same thing? Antivax rhetoric always lacked nuance, especially in the things that are actually important. I don't disagree with the notion that a 4-year-old kid that starts regressing and gets epileptic fits suffers from something brought on by the environment rather than something genetic, but this, in no way, pertains to Asperger's (which is what antivaxxers imply all the time and which gets them busted)
>>
At that point, however, I simply stopped caring.

If your kid is functioning on the level of a three-year-old, throws shit and punches holes in the walls, the most likely answer is that you're a shit parent anyway (either because you were cursed by god or because you're on a shit ton of prescription drugs and drink). Concordingly, you deserve such a child.

Seeing such parents throw tantrums (just the same way their severely retarded kid does), breakdown, see them start screaming. I feel like there's also a good chance that the parents never were particularly high-functioning themselves in the first place.
>>
>>16162637
>your le vaccine-autism theory
I'm not OP, I don't think vaccines have much of an effect in the rise of autism cases we've been seeing over the past decades. I do accept the idea that autoimmunity plays a major role in autism, especially the regressive cases so I wouldn't completely rule out the idea of excessive vaccinations causing an extremely marginal increase in the chances of a child developing autism, but I think lack of diversity in the microbiome serving as an immunomodulatory effect is probably one of the more critical causes of certain subsets of autism.
>Yes, but why do we pretend that this "autism" and asperger "autism" is one and the same thing?
We shouldn't, merging asperger's with autism has done extreme damage to researching the actual special needs type of autism, I even think the concept of "autism" should be done with because all they use to diagnose it is the behavioral symptoms, while the more traditional definition of it is that it's a genetic disorder present from birth, and notion that children can develop it a few years into their life betrays that. Initially the term autism came from the behavior of schizophrenics on their negative episodes, and the etiology has been shown to have multiple causes meaning that it should be reclassified as a syndrome and not a disorder. But even aspies can suffer from some of the physical symptoms of autism such as poor coordination, gut dysbiosis, occasionally epilepsy.

Aspiring doctor brain dead after friends pushed him into lake knowing he can’t swim

https://nypost.com/2024/05/04/us-news/louisiana-aspiring-doctor-christopher-gilbert-left-brain-dead-after-friends-push-him-in-lake-to-drown/

An aspiring medical student was left brain dead last month when his friends pushed him into a Louisiana lake knowing he couldn’t swim — and then looked on while doing nothing to save the drowning man, according to a report.

Shocking video shows the group casually peering into the water moments after they shoved Christopher Gilbert off the dock at Lake D’Arbonne in Farmerville on April 14.

At least one woman can be seen slowly entering the water before abandoning the rescue mission.

It was another 10 minutes before a patron at a nearby restaurant intervened and yanked Gilbert back to land — just in the nick of time.

The World Health Oganisation's IARC classifies female contraceptives (steroids) as class 1 carcinogens. However, most US health sites downplay the associated risks and complications. Meanwhile, male steroids are heavily restricted in many countries despite being classified as only class 2a carcinogens. Male steroids are also highly effective (99%) as contraceptives. What are they concealing from us?

you'll notice that tobacco, alcoholic beverages and uv tanning salons are also class I carcinogens. I think what matters is to properly inform the women who wants to take the pill, and I think for a majority of women, the benefits of having controls over their pregnancy / family planning outweights the side effects. I'm not familiar enough with anabolic steroids to explain why they're prohibited for men
