Researchers have adapted techniques from functional neuroimaging to map internal "functional networks" in large language models. By presenting the model with task-based prompts in an on/off pattern, they identified distinct networks preferentially activated for domains like political science, radiology, and paleontology.

They found the greatest overlap between networks for radiology and pathology, suggesting shared semantic representations. The activated connections were fairly consistent across runs with similar tasks, and strongly predicted the prompted task in held-out experiments.

This offers a new way to peel back the black box of large models and understand their hidden organizational logic. It could help explain failures, selectively target parts of a model for fine-tuning, or monitor "alignment" during inference. The techniques parallel those used for decades to map functional networks in the brain.

I think it is the flippant manner in which they expose the security concern and recommend a product few would actually use.

I cut myself significantly less with a single blade than I ever did with the disposables. Disposables breed laziness for "it's good for one more shave" syndrome. And you tend to get razor burn frequently. With a single blade "wet shave" you tend to take a bit more time and make shaving an art and "manly" routine. Emphasis technique and you actually feel the difference of blades and wearing. I suggest purchasing an amazon tester pack of blades, eventually you will find ones that work. You can get a decent weight Parker shaving kit with a badger hair brush for the amount of a few blade packs, but they last forever.

There are tons of videos online with technique.

Stick with it for a few weeks until your skin adjusts to the awesomeness of the shave. Invest in a good alcohol free aftershave moisturizer.

As an American the phrase "chiefly freedom" sends shivers down my spine. I'm sure you don't mean it as such, but it sounds so narrow minded and "rah rah" patriotic. I wish America was "chiefly education and free thought".

I'm more upset on how blatantly racist the initial and other tweets seem.

No rechargeable remote? Should of had a simple dock on top to charge the remote and another dock purchased with the game pad. No need for batteries.

I always thought that the digital stock market should take a page from the cryptocurrencies and add a digital proof-of-work that will cap the speed of a transition. A "temporal tax" would keep the system from wild swings and reactions, similar to what we saw a few months back.

Doesn't work well in my 9.4 T MRI environment :)

The joke between us engineers at work is to estimate the project time, then multiply by pi.

I think most of your repliers are forgetting about Blackwater. (/tinfoil-hat)

see above, pls.

As far as I can tell, the x-ray works similar to the dentist office. While, the basic idea behind the active backscatter mm-wave is similar to radar. It is my understanding that the majority of the TSA owned mm-wave machines are active. You have a number of antennas that pulse and listen. I would need to look up the specs, but I suspect they are in the 75 GHz range which is above the oxygen absorption (60 GHz) but below more expensive technologies in the 100+ GHz range. There are a number of "cheap" technologies that have emerged for radar in this range on the market at the 75 GHz frequency, and I think it is being driven by this technology.

All in all, the mm-wave at the powers they use are harmless. The depth of penetration to the skin is sub millimeter and your body dissipates any heat that would be generated. It is most likely a pulsed system and your overall exposure time is small. But, the most fragile part of your body is your eyes. The capillary blood vessels are much smaller and wouldn't dissipate the heat as readily as the body. And it is my professional opinion, that overtime, it could do damage to your lenses and cause cataracts. I would love to get a grant to study these effects.

As far as I have seen, there are no IEEE specs on specific absorption rates (how much heat energy is created by being irradiated with a source), they are typically categorized as "body", "head", and "appendages". If anyone has information on specific body parts (I personally need it for teeth and fingernail work I do) I would be very interested in the FDA specific absorption rates.

When you close your eyes your eyelids will dissipate any heat generated and the mm-wave will not penetrate through the skin. One interesting test would be if anyone could get what the images look like, and see if you can tell where the eyes are. If there there is a difference in the backscatter, that would mean that the mm-wave is being absorbed differently in the soft tissue of the eye.

In my professional opinion, just close your eyes. If you fly once a year, it probably isn't a big deal. If you fly all the time, I would close my eyes.

Agreed, I opt-out every time I can. This gives me a chance to talk to the TSA agent. This puts human faces on the, typically, blurry screen of human mass.

When they ask why I opt-out, I explain about the numerous times I have filled out the comment cards mentioning the real danger of cataracts because you don't tell people to close their eyes. Explain that my engineering background fully understands both the x-ray and mm-wave technology. I explain that even the weak, yet not disclosed, powers of mm-wave back scatter can, over time, cause damage to your eyes.

This gives them something to think about, that isn't the typical "freedom" complaint they hear. I hope, one day, to overhear a TSA agent tell people to close their eyes.

First, the threat to your eyes is real. But, my underline reason is by making people close their eyes it will give a sense of vulnerability that the current systems don't have. I am hoping, one day, that this is the tipping point needed for more people to opt-out.

An engineer can dream.

I don't think this is the case.

But on a smaller scale: The Bush administration would put out a piece of legislation that was a hyperbole, watch the public/democrats react, then ram through a "less worse" bill in the guise of compromise.
