It's interesting because when dealing with inanimate objects, the term manipulation is pretty neutral. It's only when we refer to people that the term manipulation takes on a negative implication.

I think it's the lack of reciprocity that's the difference. If someone manipulates me to be more productive at work, but I don't see any benefit in return, it's different than if I get a raise or a bonus as a result.

Even if I do get a raise or bonus, the manipulation can violate a personal boundary, and as a result, have mixed positive and negative consequences.

I did read the article, but it lacked important details on how the data were acquired. Here's the link to the actual journal article:

https://www.nature.com/articles/s41598-023-27444-3

They used a distributed acoustic sensing (DAS) interrogator unit (hooked up to underwater telecom-grade fiber optic cables) to collect the data. I am more familiar with DAS, having processed seismic data derived from the "raw" strain-rate measurements it produces (one could also derive temperature changes along the fiber in other configurations), but in my case the DAS interrogator was hooked up to a fiber optic cable specifically designed for that use case. My understanding is there are quite a few differences between those types of cables and the ones used by the telecoms (in terms of glass quality in the core as well as the thickness/type of materials used to protect the core). My understanding is there are also quite a few differences between the hardware used to "interrogate" the fiber (e.g., the DAS unit vs. the OTDR unit you mentioned earlier). All the differences amount to some kind of loss in sensitivity to the smaller amplitude seismic waves.

So my question (from before) is more related to how sensitive the hardware/diagnostics are on your end? I would have assumed they are geared more towards identifying the outcome from a high-strain event (e.g., one large enough to at least slightly damage the core or materials protecting it). Would you be able to identify lower strain events (ones that do no permanent damage) with your type of hardware/diagnostics? Take my earlier example and assume you had >10km of subsea telecom fiber optic hooked up in a typical configuration for two-way communications (say between an island and the mainland). If somewhere in the middle, you had 1000s of scuba divers lightly squeezing (or gently tapping) a 500m section of cable for a few seconds (or a few minutes even), would that be enough to disrupt communications? Or would it introduce a negligible amount of noise on the signals?

I ask because that hypothetical level of strain is probably still an order of magnitude greater than the strain imposed on the cable from a passing P wave (which would be detected in the early warning system and used to warn about potentially damaging waves arriving 10s of seconds later). If the answer to the former is "no" and the latter is "yes," then I suspect that advancements in algorithms alone would not allow someone using typical telecom hardware to detect these subtle changes. New hardware (i.e., DAS interrogators) would be needed for that application and would likely need to be hooked up to spare/dedicated fibers (assuming there are multiple glass fibers in a single cable) not actively being used for communications

Well if you are already on a wait list maybe consider seeing a myofuntional therapist in the meantime - they often have a network of airway focused dental professionals and ents that take it more seriously, you might get info that is helpful. Maybe start with looking up the website for the breathe institute, lots of info and a list of professionals in your area that have focused on this area of study. Good luck!

Not from a gun store. Private sale, yes. Noone in thier right mind risks an FFL and a visit from the atf to sell a gun. He'll, if I owned a gun store I wouldnt sell a personal firearm to a friend w/o check just to make sure the feds don't show up. Your point is valid that there are ways around that check but using those avenues have strict lanes to stay in and I can't see a state passing a law that any ffl dealer would lean on to get around it.

If the hazmat suit isn't appropriate PPE, that's part of several good reasons to dispense with it. That's why the IAEA PRTM-5 makes specific recommendations for considering both the use and non-use of PPE in a way that considers both the capabilities of specific PPE and their relation to the specific hazard.

For example, an individual who had to work quickly in an environment with pure neutron radiation would not wear a leaded apron. I'm happy to go into more detail if the topic interests you.

Nothing that I read offered a solution. They implied that pre-carbonating gets over the problem of cracking of the concrete as it carbonates, but that isn't a serious issue. Corrosion of reinforcing steel can and does occur in uncracked concrete if the pH is not kept alkaline. The permeability of the concrete to air is ample to allow this. Subsequently cracking occurs because the corrosion products have a higher volume than the steel they replace. The cracking is a result of the corrosion, not the cause of it.

I can understand that. I'm not a big fan most art that you would find in galleries, I don't understand it and I don't think it really speaks to me. But I can understand how if you think of the right context it can help you, on a particular if you think about the technique and how the artists use certain tricks displayed some skillet can enhance the value of the art, or your appreciation

It's like how a musician will appreciate certain musical compositions for their challenging nature or for the way they break conventions or do something interesting or new.

I work in research, and when I see a really elegant research design, I always appreciate the study a bit more. Is somebody from the outside world who doesn't see that elegance as easily because it's outside their experience probably would not feel the same. On the contrary, they might find it a little disconcerting because it's easy to misunderstand or it sounds confusing or whatever.

At any rate, whatever works for people is what works for people.

I think this article is just acknowledging people like me. I don’t care about most of those bullet points for many works of art, but knowing how something is made or done is of value to me. So even if I don’t care about the finished artwork itself (like instances where those bullet points don’t apply to me), I can still find interest in something about it.

What moves people changes with the times. Just like what we thought was funny decades ago kinda falls flat now. Historical context is important.

I’d rather someone who has never taken an art class or art history read the placards and walk away with a better appreciation for fine art, than that same person run through a museum in a fifth of the time to see everything and not actually get anything from it.

My personal enjoyment isn’t more important than increasing the world’s appreciation and support of art. Those people that read the placards and stand in you way for all of two minutes are potential donors and volunteers. They might be inspired to purchase local art from upcoming artists for their walls instead of mass produced stuff from a corporate store. They might pass on that new found love of art onto their future partners or children.

If anything I feel like making art museums even more easily accessible with mini documentaries in a small seating area would be fantastic. Art should be for everyone not just the people that have the education or time to learn about it.
