Expensive by UK standards, but cheap vs Bay Area: Cambridge UK. I've not been anywhere else that has the density of interesting people doing interesting stuff. London is not far if you need to break the bubble (and Stansted Airport eve

generally = sometimes it is less expensive. I guess it wasn't clear, but my point was that healthcare is on average much more expensive in the US.

"In the US food is generally cheaper than it is in Europe, medical care generally more expensive." I'm not sure when medical care is cheaper in the US. Within the VA system, maybe? Also, the ranking does not stack up against

I did my PhD in a lab with a few people do 3d printing of organ scaffolds. Many (all?) of them used gelatin over collagen - I think the main factor was cost being much lower. There may have been something about gelatin being easier to extru

Its great that the NFL is supporting biomechanics research (and will hopefully help the sport as well). However, while the models are open source they seem to be created for LS-DYNA, which is a fairly expensive program. I'm not aware o

I don't think it's 100% of either of these (outcome vs tech used). If its true research, the outcome isn't known. There are major benefits in developing technology for it's own sake, which then provides tools that can be

To be truely useful as a diagnostic in major decision-making, it needs to be 90-95%+ accurate. But unfortunately there isn't anything close to this yet. High blood pressure, for example, probably more accurate than the retinal image te

There is an interesting additional link between cardiovascular disease and bones: calcification (calcium deposits in arteries) also seem to have some link with heart attacks and strokes.

Seen similar things, with the effect of learning curve being fairly massive - particularly for the first 5-10 procedures done. Really understated in the article for being a fairly major factor.

Agreed that multiple stents and multiple vessels can be stented in one cath session. My point was more that there isn't very strong evidence or criteria for what constitutes a vessel that should be stented versus which should not. Wors

People in a clinical trial typically don't pay for the treatment (or placebo).

Stents are an incredible piece of engineering, but probably are over-used (particularly in the USA). There are a few issues at play: -Chest pain -Artery narrowing -Heart attack risk They aren't the same, although there is correlation b

Agreed. A large amount of time also goes into things like making figures, which is mostly time-consuming grunt work. I think the key is differentiating between creative work (which is better to be done deep with fewer hours) and grunt work

In some ways 25 years is an ideal amount of time - means that key patents recently expired. A similar factor lead to the explosion of consumer 3D printers about 5 years ago.

I learned mostly from MATLAB documentation. Good if you want theory and implementation, and most capabilities can be done with open source equivalents if you don't have MATLAB. https://uk.mathworks.com/products/com

I think you've amplified an out-of-context statement to try and start an argument, and in fact part of my point is that the main responsibility would go to the teacher. But I would say there is still some responsibility for a creator -

Protest here was more of 'make a comment on'... I think its a cool site. I was thinking of showing it to high school students I teach summer courses to, but its probably not appropriate for them. That's why labels are helpful

I was going to protest the full Lena image without a NSFW warning, but hadn't realised the full story of its history[1]... The site in general is a beautiful work of art, a great blend of attention to detail with comedy of computing in

I think the incentives of different investor types should be considered. If you're a speculative investor and plan to own for <1 month or so, who cares about voting rights. If you're a long term investor, say >2 years, non-v

There is different math for each system. In the USA: if riskFromTreatment <= riskFromNoTreatment: doTreatment In most public systems: if (treatmentCost <= someThresholdPerBenefit) && (riskFromTreatment <= riskFromNoTreatme

This would be a pretty big step - right now there is a big incentive to be first to publish. Often the researchers who would be doing the replication are competitors, who are racing to publish their results first. Part of publishing is to p

Usually, if you want the full details you look/ ask for the thesis or full report that the journal article is the condensed version of. Most journals also allow supplementary sections for more detailed methods. If its too long, people

And U of Toronto has one of the top Neural Networks groups anywhere. UBC is also a great university in a nice city.

You work from the key stops (decimal and comma), then go backwards to the only steps that can get you to these stops.

Probably not intended, but the implication this argument leads to is for the development of regulation in use and censorship - like the FCC for radio.

So what's the take-away? Make many high risk bets in hoping one will pay off? Newton is an exception as well. While his biographers down-play his failures, he is also credited (at least in High School Physics) with things that were the
