sci-hub doesn't get new research papers any more, and the new alternatives are all much less user friendly. As far as I can tell, wosonhj.com is what's currently recommended, where you have to post in a forum and wait for either a bot or a human to send the paper to you. Other alternatives, like annas-archive, nexusbot or STC all didn't have the paper I was looking for.
I just want old sci-hub back, honestly.

For all those other non-Americans like me who are not completely up to date on this:
Trump was barred by the Colorado Supreme Court from appearing in the Republican primary in the state because of his role in the January 6 insurrection, reversing a previous decision by a lower court that ruled that while Trump did engage in insurrection, he's technically not an "officer of the United States", which apparently makes insurrection OK. This will almost certainly go to the US Supreme Court which appears likely to overturn it, given some of their previous decisions and the fact that it contains 3 Trump appointees. Colorado is a solidly Democratic state which is very likely to go to Biden anyway, but the decision still seems quite important, given that this is the first time something like this has happened.
Trump's campaign called the decision "undemocratic", Biden's campaign declined to comment.

I used the Video DownloadHelper plugin for Firefox, the same plugin exists for Chrome too and should work. I'm sure you can find some websites that let you simply paste the URL too and download the files that way, if you don't want to download a plugin.

Here's the study, for anyone who wants to read it. It's surprisingly short and open access.
A few things:
The participants took Wasabi supplements once a day for 12 weeks, not just normal Wasabi. In each pill, there was 0.8 mg of the active compound (6-MSITC). Quick googling gave me the following for the level of that compound in actual Wasabi:

Another study determined ~550-556 μg/g of 6-MSITC in wet weight of wasabi root [10] . The present study observed a concentration of 120-150 μg/g wet weight of 6-MSITC in stem and rhizome blend.

In other words, you could actually also get the same amount of 6-MSITC that was in the supplements by eating a few grams of regular wasabi each day, assuming that the processed stuff still has similar levels. The abstract provides a reasonable summary of the study, and of the fact that it agrees largely with some previous science on the subject (although there's not a lot, two studies in small journals):

Cognitive functions decline with age. Declined cognitive functions negatively affect daily behaviors. Previous studies showed the positive effect of spices and herbs on cognition. In this study, we investigated the positive impact of wasabi, which is a traditional Japanese spice, on cognitive functions. The main bioactive compound of wasabi is 6-MSITC (6 methylsulfinyl hexyl isothiocyanate), which has anti-oxidant and anti-inflammatory functions. Anti-oxidants and anti-inflammatories have an important role in cognitive health. Therefore, 6-MSITC is expected to have positive effects on cognitive function. Previous studies showed the beneficial effects on cognitive functions in middle-aged adults. However, it is unclear that 6-MSITC has a positive effect on cognitive functions in healthy older adults aged 60 years and over. Here, we investigated whether 12 weeks’ 6-MSITC intervention enhances cognitive performance in older adults using a double-blinded randomized controlled trial (RCT). Methods: Seventy-two older adults were randomly assigned to 6-MSITC or placebo groups. Participants were asked to take a supplement (6-MSITC or a placebo) for 12 weeks. We checked a wide range of cognitive performances (e.g., executive function, episodic memory, processing speed, working memory, and attention) at the pre- and post-intervention periods. Results: The 6-MSITC group showed a significant improvement in working and episodic memory performances compared to the placebo group. However, we did not find any significant improvements in other cognitive domains. Discussion: This study firstly demonstrates scientific evidence that 6-MSITC may enhance working memory and episodic memory in older adults. We discuss the potential mechanism for improving cognitive functions after 6-MSITC intake.

They tested the study participants once before and once after the 12 weeks of daily wasabi supplements. The participants were not tested for any long term cognitive effects.

As someone else has pointed out here in the comments, the study does list a Wasabi company as one of the sources of funding:

Funding
This study was founded[sic] by KINJIRUSHI Co., Ltd. and the Japan Society for the Promotion of Science (19H01760, 22H01088).
Conflicts of Interest
This study was supported by KINJIRUSHI Co., Ltd. The funding body had no role in the design of the study, collection, analyses, or interpretation of the data, writing of the manuscript, or the decision to publish the results.

Also, I don't want to poison the well too much, but I feel like I should mention that the editorial board of the journal resigned in 2018 because the publishers "pressured them to accept manuscripts of mediocre quality and importance". Doesn't mean it's all bad, but it's a very early study and more research should be done.

I believe this is the entire first season for streaming:
https://www.avf2.cn/index.php/vod/play/id/485708/sid/1/nid/1.html
You may have to wait a few minutes for the video to start, but it did play for me eventually.
Edit: Only 11 out of 14 episodes.

Got a point there, but it's what the sources say. One possibility might be that it's the teenagers that got scammed (or even just filing the complaint?), but their parents' accounts that got emptied. This part of the report is unfortunately really lacking in detailed descriptions of the data.

The headline is pretty misleading. Reading the headline, I was imagining Nigerian Prince scams. But in the article, they state "Compared to older generations, younger generations have reported higher rates of victimization in phishing, identity theft, romance scams, and cyberbullying."
Teens get bullied more than the elderly? Say it ain't so!
While GenZ is, according to their source, also the generation with the highest percentage of victims if phishing scams, it's actually millenials that fall for identity theft and romance scams the most.

The article also states that the "cost of falling for those scams may also be surging for younger people: Social Catfish’s 2023 report on online scams found that online scam victims under 20 years old lost an estimated $8.2 million in 2017. In 2022, they lost $210 million."
The source for Social Catfish's claim is data released in 2023 by the FBI Internet Crime Complaint Center. According to that data, in 2022, there were 15,782 complaints for internet crime by victims under 20 totaling $210.5 million in losses. In the same year, there were 88,262 complaints by victims over 60, totaling $3.1 billion in losses.

Every generation since the beginning of times has claimed that the following generation was rude, stupid, and stopped doing things the "right way" like we used to do in the good old days. It has always been bullshit, it will always be bullshit. Stop stressing, the kids are alright.

Thank you for the comment!
You can see the parts in the pictures in the post. Yes, as far as I can tell, only a few layers were printed, then I lost adhesion. The build did stay on the tank's floor, from which I had to scrape it off. The machine kept going until "finished", but did not print anything for more than 90% of the printing process.
I will try angling the parts next time, did not think it was necessary since the first test print, which was not angled, went so well.

Thanks for the suggestion! Just trying to understand, why would reducing the exposure time for the bottom layer help with adhesion?

No worries, I had no idea what TSMC even is and was confused by these settings having two different numbers, but now that you've mentioned it I was able to Google it and I think I understand now.
Anyway, thanks for the suggestion and for helping me learn, I might try that!

It completed, but was stuck to the resin tank. No errors this time.

 

Hello everyone! As it says in the title, I very recently bought my first 3D printer, the Elegoo Mars 4 Max. Two days ago, I did my first test print, and it came out pretty good (although maybe a bit too hard, but details looked sharp). The only problem was that I somehow got an error message in the end ("error printing file data exception"), but the print seemed to have finished, so I didn't really worry too much.

I was pretty happy, so yesterday, I tried printing some more. I tried to print some exposure test files (3DRS starship https://3drs.com/pages/3drs-starship-resin-calibration-test and Cones of Calibration https://www.tableflipfoundry.com/) after slicing them with Chitubox. No error message this time, but the prints failed very early. Can anyone help me figure out what the problem might have been?

Here's some additional info:
For the first test print, I did not do any slicing or calibration, I just used the .goo file that came with the printer.
Cleaned the build plate with IPA and paper towel after first print
Did not clean or empty the Resin Tank after first print
Did not level the build plate again
24 hours between first and second print
I stirred the resin a bit before the second print, but maybe not enough
I don't know what the exact temperature was yesterday, but it was still pretty warm.
In Chitubox, I changed the settings to my printer, then downloaded the PDF with the settings for my printer/resin combo (Standard 2.0 grey) and put them in. I then dragged the .stl files into the window and sliced the files, exporting them as .goo files. I then copied the .goo files onto the USB stick and plugged it into the printer.

True, GPT does not return a "yes" or "no" 100% of the time in either case, but that's not the point. The point is that it's impossible to say if GPT has actually gotten better or worse at predicting prime numbers with their test set. Since the test set is composed of only prime numbers, we do not know if GPT is more likely to call a number "prime" when it actually is a prime number than when it isn't. All we know is that it was very likely to answer "yes" to the question "is this number prime?" in March, and very likely to answer "no" in July. We do not know if the number makes a difference.
