There is this infamous DANCAVAS study [1] in which they ran cardiovascular screening on older population and found absolutely no benefit in doing so. Note that while the linked study claims there was a benefit to screening (reduced mortality in men aged 65-69), the apparent effect was caused by improper statistics (primary endpoint did not show benefit, only subgroup analysis, which however lacked statistical power to be reliable). And indeed, their follow up study showed that there was no benefit in the subgroup. [2]

Many a dollar is wasted every year on trying to prove population-wide screening prevents mortality or increases patients’ quality of life and every time we don’t cheat with statistics we get the same answer - population-wide screening isn’t effective.

I mean Steady State Visually Evoked Potentials (SSVEPs). https://en.wikipedia.org/wiki/Steady_state_visually_evoked_p...

I am pretty sure you’re right, they are probably recording alpha waves, possibly combined with heart rate.

Decoding limb joint movements from EEG scalp recordings is basically an unsolved problem (we can barely do it in lab with implants), I doubt an advertising company has cracked it.

There is quite a number of freely available EEG software for different paradigms (one such collection is MOABB - Mother of All BCI Benchmarks, and there’s a huge number of scientific articles).

The biggest bottleneck for a hobbyist is that when using EEG, most paradigms require somewhat expensive hardware to work and that most paradigms still don’t work well with scalp recordings outside a lab environment, even when using mid-cost devices.

There’s also the issue that classifiers usually have to be quite simple because datasets are small, because they are time consuming to record (and after you remove noisy epochs, you have even less data left). Cross-session and cross-subject learning rarely works, since EEG is dependent on so many factors like subjects’ brain anatomy, the type and precise location of electrodes, amount of gel (or lack thereof) and how dried out it is, mood and focus of the subjects, a huge number of environmental factors that influence subjects’ focus and many others.

The only paradigm I have seen to work a bit more reliably than others is Steady State Visual Potentials, because you have extra information that doesn’t need to be learned from EEG (the frequency of visual stimuli is roughly the same as the one in subjects’ occipital lobe).

But the 18th century artist who did portraits and wedding paintings is the today’s (wedding) photographer.

Does it take less money to commission a single wedding photo rather than a wedding painting? Yes. But many more people commission them and usually in tens to hundreds, together with videos, etc.

An 18th century wedding painter wasn’t in the business of paintings, but in the business of capturing memories and we do that today on much larger scale, more often and in a lot of different ways.

I’d also argue more landscape painters exist today than ever.

I assume you’re talking about another country, because in Denmark there was no general curfew under Covid (attendance to events might have required proof of negative COVID test or vaccination, but shops never did).

It’s intentional and requires quite a lot of focus.

The original paper [0] mentions electrodes are placed over Broca’s area (speech production, translates words to mouth movements) and motor area (adjusts the mouth movements). It’s attempted speech, not thoughts.

There is a lot of fear in mainstream media and populace of devices decoding thoughts, but that is a significantly harder problem, at this moment on the level of sci-fi of Civilisation Type II on Kardashev scale. There is a reason why the electrodes are not over Wernicke’s area instead (language comprehension and production).

I find this distinction unnecessarily nitpicky in this context. A BCI can be implement using EEG as an input so yes, you can definitely make a BCI using PiEEG.

130dB SNR is also not too shabby for a low-cost device, I wonder how it compares in a real world scenario with some of the OpenBCI offerings. For now at least it seems to be a cheaper option to OpenBCI Cyton with a comparable performance, unless I missed something.

Grant application and advancement in scientific careers. As a junior researcher, you either publish in impactful peer reviewed journals or you don’t get your PhD. As a senior researcher, you either publish in impactful peer reviewed journals or your PhD student doesn’t get the PhD degree (this hurts both of you). Moreover, you won’t get grants so you can’t even hire a PhD student in the first place.

While scientists’ prestige might be a part of the equation, it’s mostly the academic leaderships and fonds that have brought us here.

Not only does English get you by in most big cities, a fair amount of European citizens are multilingual and often it’s the neighbouring countries that people speak the language of.

Every in-demand field of study is guarded by the all-important grade-point average from High School. If yours is too low, well, sorry, you’re just not going to study psychology or become a midwife. It doesn’t matter whether you came from an underprivileged background, did a million extracurriculars, or hail from an ethnic minority. You either make the grade for your first choice or you pick something else to study.

This is not Denmark specifically, it’s just Europe, and it’s not even true.

In Denmark there’s something called Quota 2, which is an admission track that is not based on the average, but on extra-curriculars, volunteering, work experience, …

Ofc it’s easier if you have the average and a lot depends on what subjects you choose to graduate from, but not all is lost even if you chose the wrong subjects. If you need let’s say extra physics classes, a lot of universities/schools offer pre-university courses which can teach you the subject in the summer and you can apply for your dream programme the same year.

A lot of people actually start university and then later find out it’s not what they like and switch to another programme or (trade) school after a year. Generally, in Denmark, you can study what you want, unless you’re really ill-equipped for some reason (but then you probably have bigger issues to resolve first).

That being said, I don’t know about any way how you can get into a university programme based on being a member of an ethnic minority.

In Denmark the situation is a tad different. A lot of immigrants of Middle Eastern descent have rather poor English and their Danish is much better (they need to be somewhat fluent in Danish in order to stay). Their kids’ English is however on par with “native” Dane’s kids.

The inability to blend in, IMO, is primarily language based. I have a better hold of Danish than most of my international friends and I have also felt more welcome in Denmark than them. Folks that have been in Denmark for 5 years longer, are even more homey in Denmark IME (regardless of skin colour, mind you).

This is obviously anecdotal evidence, I am sure there are some older folks that aren’t as accepting (my friends are generally young, as I am). But still, a lot of them can be open minded. I am reminded of this story a friend of mine has told me. She ran an org helping immigrants in Denmark and one of the activities she organised was connecting immigrants willing to learn the language with older folks in care homes who longed to speak to more people. An older resident lady has told her once that while she is not keen on those immigrants from Middle East, Muhammad is a very nice person whom she enjoyed spending time with. So much about accepting other cultures and people is about exposure (probably why cities are more liberal than countryside)

While US has ratified the Universal Declaration of Human rights[1], I am not sure how binding it is. There are also two Conventions about statelessness that US has not signed, and maybe that’s why similar revocations of citizenship has happened in the past[2] Even though link discusses a case where a terrorist lost the citizenship, not a law-abiding doctor, the grounds for revocation were the same - diplomatic immunity at the time).

Abstract is not (only) the main finding of the study. It’s often a mini version of the article, with a background, methods, results and conclusion.

The length of the abstract in the linked article is well justified, in my opinion.

Some extra context:

EEG has poor spatial resolution, but great time resolution. It measures electrical activity.

fNIRS has a great spatial resolution, but poor time resolution. It measures blood flow in specific parts of the brain.

I doubt that rabies has evolutionary developed to target dogs. It’s just a “happy” accident that dogs are so plentiful and can infect many other animals (until recently at least).

If I had to guess I’d say rabies had evolutionarily targeted species that today are largely asymptomatic and can easily survive a rabies infection, like bats or birds.

No, that’s usually not how it works. People usually get called a conspiracy theorist for making claims not based on (scientific) evidence. Often conspiracy theorists are not experts in the field and cannot distinguish between good and bad arguments (even though some conspiracy theorists have a uni degree in the field).

Questioning a study does not a conspiracy theorist make, quality of of your arguments does.

Hopefully this will never be the case.

On the other hand it can be used to detect micro sleep in drivers and there it can save lives.

So yeah, as with any tech you can use it for good or bad and you should not use it for everything

Most likely because they are de-facto monopoly, so they will take as much as they can.

I am not a CS student, but I do study in a field where computers, maths and clever algorithms play a big role (biomedical signal processing). Also I am not necessarily a good student - I care only somewhat about grades, and if I find something that is not part of the curriculum, but is more interesting, I pursue it instead, sometimes at a cost of a better grade.

Indie programming is fun for me in short term, but research is more rewarding in the long run, because of the positive impact and opportunities it brings. Research is also more varied (includes not only writing code, but also math and words and also working on study design, statistical analysis and subject testing).

Healthcare tech can be both, the latter is sometimes called biomedical engineering. Siemens is also known for the latter (development and selling of medical devices). Check Siemens Healthineers if you’re interested (I have no affiliation with Siemens, but I dabble in healthcare/biomedical tech)

I read it the same way. The signal analysed comes from the sensorimotor cortex, so this is less “words you are thinking of” and more “words you are attempting to speak”.

Fitbit gives you a nice animation when you hit your goal and a star for that day in the history overview.

Additionally, it’s great if you add a friend in the app to compete for the max steps in the last 7 days.

Do you maybe have an example or two at hand? I would be interested to read some.

According to the article he did:

EDIT: it seems that people have been making Tate clips and uploading them to TikTok and those are also the ones that got banned.

TikTok has also banned an account belonging to Mr Tate as part of an ongoing investigation to remove content that violates its policies.

A TikTok spokesperson told the BBC: "Misogyny is a hateful ideology that is not tolerated on TikTok.

"We've been removing violative videos and accounts for weeks, and we welcome the news that other platforms are also taking action against this individual."

I don’t think your article applies here - it seems Andrew Tate has created misogynistic content on each platform that banned him. The timing might be suspicious, but ultimately, TikTok banned Tate because of the TikTok content he made, Google banned him because of the YouTube content and Twitter banned him based on his tweets.

I am also confused about why do you refer to people like Tate as ‘villains’ in quotes. The dude is a star of incels and like-minded women-haters. The world is better off without his content.

Given that we are talking about a website, what is the worst legal enforceable thing you could agree to in this way?

Things like “rights to your first born” are illegal and unenforceable.

“you must visit the site everyday from now on” is unenforceable.

“or we close your account” - they don’t need your consent for that

You generally don't need a consent for gathering data that is required to run the site.

But if you use the data for analytics purposes, you do need the users' consent for that, even if it's the same data that you use for operational purposes.

If you are based in EU you could try to go the legal way and demand the decision about your account is not taken purely by an algorithm (there is a GDPR clause like that). I don't know how enforceable it is, but I guess it is worth a try.
