The "whistle-to-whistle ban" was always poor legislation. By its own terms it only suppresses TV betting adverts in a defined window and lapses at 9pm, and it never touched the categories that actually make up most of the advertising we see; shirts, hoardings, and structural branding, etc. It was an utterly pointless measure that serves to achieve not a single one of it's initial goals.
I help engineers design traditional scanners (Philips, GE, Siemens, etc). To be frank, this statement stinks like utter pig shit.
Some PE bro preaching miracles about a technology that I am sure they are in some way invested in making profit from does not convince me of it's legitimacy. My base instincts, from the unfortunate experience of working daily with PE bros, tell me the opposite in fact. It gives déjà vu of the Theranos hysteria.
The authors report explicitly state that the system's resolution does not match clinical CT or MRI. The elevational resolution is 15–25mm, meaning each slice is effectively a thick 2D section rather than the fine isotropic 3D volume MRI provides. MRI also delivers far richer soft-tissue contrast; this device produces only three contrast types (reflectivity, speed of sound, attenuation), and because it uses a low 1MHz frequency, the reflection images come primarily from tissue boundaries rather than from internal tissue texture.
I could see this being valuable for adipose tissue mapping or fatty-liver monitoring at a large scale, as the machines would be significantly cheaper, but this isn't some revolutionary magic bullet like the Twitter post is insinuating.
As someone in the medical imaging field, are you aware of anyone working on passive sonar for medical imaging? I'm curious, as it's something that I've always thought would be fun to work on.
For context I'm in engineering consultancy, so by no means an expert but I probably have enough experience to be on the other side of the Kruger curve dip.
Passive sonar in the naval sense means listening only, not emitting. Do you mean imaging that relies solely on acoustic energy already present and emitted by the body? If so, then generally no. You have two types of "passive" imaging. First would be hardware-passive, as in MR elastography (most common), where the patient wears a transducer pad, and vibration is actively generated by a driver. You've then got algorithmically-passive, which is more analogue to passive sonar, reconstructing tissue stiffness from ambient broadband vibration without the emitted probing pulse, but that is very much entirely academic. I guess the question would be, why is it worth pursuing when you have something like optical coherence elastography (OCE) for non-invasive profiling. Doing it using noisy ultrasound method becomes redundant. There are other methods, but the outcome is the same.
Generally (this is true for all systems, not just humans) you need to induce energy into it to more effectively measure it's output. Think of it like a bell - if I want to hear the note it produces, it's much easier to hear what this is if I ring it with a hammer. Granted, it will be "passively" resonating to a point where, with a sensitive enough sensor, I could probably pick up the output without the hammer - but that is a pointless problem to solve. I could hit a bell with a soft hammer a million times over without causing damage to it. The lifetime of the person hitting it with a hammer is far shorter than the accumulative damage to the bell before it breaks. The same is true for humans. You could effectively run a very low-energy, 60Hz vibration through a person (which is how the pads work) for multiple lifetimes before it would cause significant damage, so there comes little point in solving that problem. As such, true "passive" imaging is functionally pointless if your outcome is "safely image a patient". You're overengineering your solution to solve a problem that is only relevant if your patient was planning on living for 1000+ years.
I'm thinking passive, as in using only acoustic energy that is already present. Partly it's about minimising irradiation, which you are saying is not a concern.
The more interesting aspect to me is whether the ambient emissions carry useful information. I recall a paper from a few years ago about yeast emitting sounds (mechanical vibrations) in the kHz range. I guess the question I am interested in is "what does life sound like at the cellular level?" Maybe it is silent, but my gut says it's probably making some sound, even if it's very weak. The questions are then along the lines of "What does a healthy cell sound like?", "Do different cells make different sounds?", "Do sick cells make different sounds to healthy cells?". It's absolute pie-in-the-sky stuff, but it would be fascinating to know.
My background is radio communications (with some acoustics) and radio comms has a history of things that used to be considered random noise turning out to be useful signal as processing has developed to the point where signals can be resolved. For example, multipath reflections used to be considered just random interference until the invention of MIMO, at which point they became useful signals and comms systems took a leap forward.
The one thing British people do preen about with regards to technology is cars, but I think that has more to do with the cultural influence of Top Gear than it does the history.
I'd also argue that while Softbank has capital ownership of the company, the leadership structure and how that capital is allocated is still done within the UK with standard board oversight. I know a few of the leadership team personally, and they have a wide remit, almost more so than a public company might do.
The author is a Dutch journalist with no technology background. I wouldn't jump to get my information from this source. As a person who works in the UK semiconductor industry, I noticed 4 or 5 glaring holes in the article in just the first couple of paragraphs.
I got to the second sentence ("Europe is pouring more than €2 billion into sovereign cloud initiatives") before I realize the author either doesn't know and/or didn't care to research properly.
While I do disgree with the "state funded media scope" - I'd go as far as saying the BBC has become so fearful to rock the boat in any way that it is at risk of becoming a redundant source - I do think the lack of "competition" for BBC funding leads to a worse journalistic rigour. It's not the centre of excellence for journlism it once was, and is often looked down on when compared to other paid news outlets like the Economist, Atlantic, the FT, et ceterea. Adding an element of competition into the equation could make for better journalism, but equally, that would likely require more funding in the end.
You're implying that Sales, Marketing, and Distribution is not a valuable service by saying 30% is not reasonable. I work in the electronics industry selling components. Suppliers regularly give us 30% margin, far more on some products, despite the upfront cost of making a new microcontroller or FPGA being far in excess of the most expensive video games ever made, with our value add being, to be frank, much less than Steam. 30% margin is about average for distribution, be it food, minerals, cars, or any other industry.
If I didn't have Steam (or equivalent service like GoG), I wouldn't buy new games. That's just reality. I would play the same games I have for decades. Instead, Steam has created a very effective recommendation engine that gives me a great selection. That's more than worth a 30% cut.
I want to make clear to the US folks here that there's about 2 or 3 cafes that still sell traditional eels, and it's explicitly a London food, not wider British cuisine. From the number of videos and articles I see about them though, you'd think the country was covered in Eel cafés. Honestly, covering them at all is tabloid ragebait content at this point.
It's a European issue because we look to the US and now appreciate more than ever the need to introduce barriers to stop temporary fascist governments doing the same permanent damage they have done in the US. Our democratic systems are just as vulnerable to populist leaders taking power. One of those barriers we must erect is the elimination of corporation with unfettered access to institutional data that can be used by fascist governments to maintain or grow their power base.
Wow. I picked up a copy of Hyperion this morning while taking a random stroll through town - something I rarely do during a work day anymore. I popped into a book shop on a complete whim, and picked it up as it had been on my list for a while. The coincidence feels deeply uncanny.
Totally agree with this, too! The books are great and I’ve read all four a few times over, but the audiobooks are something else. The guy who reads them manages to strike a near perfect balance between “reading” and “acting” that is just such a pleasure to listen to. I think we must have listened to it beginning to end about another three or four times as a family during long car trips!
That's the thing. It is acting. All the characters are played by actors. And they just simply nail their parts. You're right that it's an equal and almost perfect mix of acting while not changing the tone or impacting the content via the same acting process.
It legitimately is the best audio book I've ever heard. I think it's because their voices and tone and cadence matches what I hear in my head when reading the book.
I started reading it for the first time this week. It’s just a statistical anomaly… but humans are wired to notice and feel coincidence; it connects us to space and time in a way that must have helped make religion more believable.
