Importance of Design Simulation in Product Development
What is Design Simulation Service? It is a tool that is mainly used by engineers and designers to test their designs to identify any potential errors before building that in reality. The main benefit of using a design simulation service is that engineers can design their product/ construction without spending any real resources.
Complex Problem Solving
Design Simulation Service can also be used for complex problem-solving. For example, you as a construction engineer want to know how much pressure can your design hold before collapsing into the ground. Or a car designer wants to taste the effectiveness of the new safety. All these problems can be easily solved in a design simulation service accurately.
In order to solve these complex problems, engineers use FEA modeling services and Fatigue analysis services. 
Accurately Calculate Effects of Various Factors
Finite Element Analysis is a numerical method used in computers to solve complicated problems. This method uses math and geometry to simulate the effects of various types of forces on a structure. It can accurately show the results of all those forces and identify structural errors. As a result, designers can easily understand the errors and update their designs to overcome that failure. 
One problem with the FEA simulation is that it cannot predict the lifetime of your structure. Life expectancy is a very important part of engineering. It refers to the expected amount of time your design and structure can hold themselves. After the age of life expectancy, the structure starts to break and it becomes very risky to use it.
Calculate Structure Life Expectancy
To measure life expectancy, engineers use Fatigue Analysis Service. Fatigue Analysis Service evaluates your model with varying loads of pressure and identifies any susceptibility to fatigue damage. One pre-requirements of fatigue analysis are the stress result from static analysis. This analysis tool uses stress results and the loads your input to determine the load variation of one life cycle. With the data of one life cycle, fatigue analysis can estimate the number of cycles your model can go through before starting to break. Thus, it calculates long life and long damage. With the stress and load data, it can also determine a factor of safety for your model.
Test your Model to its limits
With this 2-design analysis tool, you can easily construct a practical virtual model for your structure and do a random test to make it perfect.
For example, you are given the assignment to construct a bridge for the transportation of semi-trucks that usually carries 80,000 pounds. So, the first thing you need to do is create a draft model by observing the spot, and determining the length and width of the bridge. Then you need to do is estimate how strong it should be. You determine all these factors from your observation of the place and given data. Now you test them by constructing a digital model using Finite element analysis services. You test it with random factors like weight, fire, and weather and eliminate all structural errors. Now what you need to do is estimate the life expectancy. To do that you need the stress results of your model and the number of 80,000 semi-trucks the bridge has to carry. 
Final thoughts
With these results, you can easily make a perfect bridge that has no potential errors and a determined life expectancy.

My thoughts on how the Milgram mv machine works based on the evidence we have:
(I know there’s been discussion about where exactly the interrogations take place, but wherever they are,) the prisoners are made to sit in a specific chair near the wall that houses the machine.
It’s ordinarily hidden, but the wall panels shift aside to reveal it when the mechanical sounds play in the dramas. As well as the walls moving, the chair transforms to restrain the prisoner and attach whatever it takes to access their brain. The fact that none of the more frightened prisoners try to run or break it makes it seem like they physically cannot. This is why Fuuta sounds so panicked, and why Amane is suddenly helpless in front of Es in their T1 vds.
(My mind conjures very classic sci-fi mad scientist machines with wires, pipes, lights, nodes, needles, etc, but I’d love to hear how other people visualize it.)
In some vds (maybe all? I’d need to check,) you can hear Es take some steps right before their iconic line -- it would make sense that for safety reasons, the power mechanism is placed across the room. Once again it could be anything, but the sound effect makes me think of one of those giant wall-mounted levers you have to pull down.
The voice dramas don’t really provide the type of crime details that an actual interrogation would reveal, and it’s odd that they’re placed before the extraction rather than after Es gets to see the new details. This leads me to believe the machine functions with priming. All Es needs to do is get them talking about their murder, so it’s on their mind.
The video produced is much like a (non-lucid) dream. Even if the prisoners figure out that this is how it works, they can’t control it just by thinking really hard about something else. The murders produce the strongest emotional affect, and that’s what it picks up on. If someone else used the machine, it would default to whatever gave them the strongest emotional reaction in the ~15 minutes beforehand, hence why Es’ video focuses on their daunting task ahead. (The Undercover theory is still a bit loose, though, given the private shots that Es wouldn't have known about). It’s why the videos are usually closely linked to the vd topics/beats. I also like to think that the reason their prisoner colors appear so much is because they’re looking at those colors on their uniform 24/7.
The bell rings to inform Es that it’s the optimal time to use the machine -- the prisoner has been thinking about things for long enough that the video will be about their crime, and if the conversation lasts much longer they’ll start thinking of other things. It’s at a different time for each prisoner because it’s based on the specific conversation. I guess Jackalope is listening in to the interrogation, timing it perfectly. (The only one that kind of messes with this theory is Yonah, because they just keep talking afterwards lol, but it could just show that the interrogation is still in Es’ control.)
Their “Sing your sins” is the final priming nudge to get them to think of their actions as a sin, revealing their guilt.
Once activated, the prisoner enters a sort of trance/sleeping state. It’s very much like REM sleep, with the machine forcibly activating neurons and recording the output. The prisoners have asked Es what they saw, meaning they don’t remember the mvs. I like to think the prisoners do experience the mv in real time, acting as the major version of themself that appears, but can’t remember it afterwards. It’s when you experience a dream, but as soon as you wake up you’re just left with fleeting emotions and memories right on the tip of your tongue.
The video plays immediately upon extraction -- whether on a huge projection or little screen depends on which room it’s in. It simultaneously saves the memory so that Es can rewatch it later (on those old TVs in the jailbreak mix). The machine downloads the song and video together, but requires special parts to retrieve them. The technology is pretty new and fragile, so if one is broken, there might be a delay between when Es can hear the extracted song and see it with the video. (That’s my justification for Kotoko’s delays -- after 9 prisoners the parts wear out, or maybe Mikoto himself overheats it with his complex situation.)
Based on the lack of conversation we get afterwards, I picture Es leaving before the prisoner wakes from the trance. The machine adjusts their brain back to normal before they awaken, restraints freed and able to return to the rest of the prison.
It’s very much like a dream, so it’s not harmful despite the amnesia/head injuries the prisoners have. It does, however, exhaust them. Brain activity alone takes a lot of energy, so forced brain activity with added emotional strain would cause them to feel pretty drained the rest of the day.

Why I personally think: 'This is Love' by Air Traffic Control could be about being Disabled/Chronically Ill 🙏
This gets really long and I'm running on no sleep making this but I've had this thought for a while and I had a surge of energy 🙏
Starting out with the very first line of the song, the opening that sets the tone for the rest of the song: "You're no good, you're no good, you could kill me and you should." For me, when I first heard this line I correlated it with love, but as I thought more about it and attempted to think about the song without the context of knowing it was a type of 'love song' (I say this loosely) I began to think about it in the context of being disabled.
For a lot of people, finding out you're disabled (especially as a teenager/kid) can feel horrible, it's a damning feeling that leaves you feeling lost.
It feels like a type of death.
The death of a life you dreamed about, the death of dreams that kept you going, the death of having that typical romcom life, the death of a future you thought you could reach.
Which, only cements itself with the next line: "I'm an idiot for thinking, this was anything but blood,"
Being disabled/chronically ill, for as much as abled people want to deny it, is a fight. It's a constant battle against your body with no surrender in sight; it's something you learn about and then have to consistently sit at the table to find ways around it, to find things that help but will never lessen the bloodshed.
The next line, personally, is the one that cements the underlying subject of disability within the lyrics: "On the wall, on the couch, on the corner of my mouth. You must like being the victim, you've done nothing to get out of this pattern of pain."
Abled people tend to assume that disabled people are simply unwilling to 'get better' and just wish to wallow in their pain in order to garner sympathy (which is laughable) from abled people. Doctors along with regular people on the street will offer advice that isn't anything other than "if I can do it so can you," or "You're just not trying hard enough," and refuse to listen when disabled people say they've either already tried it and it doesn't work, or that they are physically/mentally incapable of doing it.
Chalking it up to 'laziness' instead if an inherent issue within the culture/systems we live in.
"Washed away by the rain, you'll forgive me if I promise, and do nothing but the same." This line, to me, speaks to many of our shared experiences and traumas surrounding doctors or medical practitioners. We continuously go to doctors, ready to fight for ourselves, advocate, and just want to be heard and nearly every time they ignore symptoms or refuse to help (especially in regards to afab people).
It's... Exhausting to say the least.
"This is life until death," being chronically ill/disabled is something you can never get rid of, it's a life long aspect of your life. "Could be my last dying breath," many chronic illness and disabilities can kill you. Whether it is by the illness/disability itself or by outwards circumstances (caregivers, hate crimes, malpractice, ect).
"But this is love, love, shut up, this is love," this line just reminds me of people telling you they love/care about you while also diminishing your disability or your needs.
"Forget everything you used to know," when you're newly diagnosed, or when it's finally confirmed, it feels like you have to forget who you used to be; finding new tools and new understandings that could make you feel like a new person entirely even if nothing changed. The "rules of life" that were previously understood were now worthless with this new sheet of societal rules we're meant to follow.
"I think you better tell your friends to go," it is extremely hard to have/keep friends as a disabled person. (Especially as a disabled teenager which is where I have most of my own experience from.) Often, when you're newly diagnosed the friends you have will pull themselves back. The knowledge that they might need to accommodate or that they might not get to do the same things as before can make a lot of abled people pull away from their disabled friends.
"Stick around cause I'm about to show you, the beginning is the end." (This connects to the above paragraph about how it could be the beginning of the end of a lot of relationships)
"Yeah, I know wrong, I know right, but I just love to pick a fight," this line just makes me think of people trying (Ill intentioned) to offer advice contrary to what you know works best for your body (especially doctors) where you're then labeled as argumentive or difficult.
"I can sleep with one eye open," I just interpret this as being hyper vigilant of your disability. "If there's any sleep at night."
"I got my knife, got my gun," Your medication, "Let's see how fast you can run, you might think that you can hurt me but the damage has been done." I just thought about the medication chasing the disability and thought that was kinda funny. I could go deeper with this but it's already getting long.
"It's pathetic, I know, a jealous fool who won't let go." This line just personally hit me in the gut because for so long I was jealous of my friends who could live their lives without needing to make sure they would be safe or without planning ahead so they didn't end up hospitalized/in a flare and unable to move. For a long time I refused to let go of the wants I had for my future that I realized if never be able to get to, it was a mourning process they didn't understand which only made me even more jealous.
"If I was sorry for my actions, would I ever stoop so low?" This just made me think of all the times I had to apologize for being sick/unable to do something and it pissed me off so that's all I'm gonna say.
"Got no reason to live," Again, it just made me think of the mourning process that tends to happen when you have to let go of the life you wanted to live in the life you got.
"And I've got nothing left to give you, but my love!" This line felt like those moments when you're trying really hard, when you're putting all your tools and spoons into doing something and trying to keep other people from needing to accommodate only to be told you're not trying hard enough.
"Oh, I was hit as a kid," (refer to top paragraph)
"I was good but then I quit," most chronic illnesses that "don't show" in childhood usually get worse during puberty when your hormones are all fucked up and messy. Hensel feeling both like it's always been there and that it just spawned one day.
"Everyone that tried to fix me knows that I can't change a bit." Just...the constant ring-around of doctors that have been either unable to diagnose or unable to help.
"I've got no shame, got no pride, only skeletons to hide." Just, that odd feeling where a lot of people feel like they need to hide their disabilities to the best of their ability.
"And if you try to talk to someone, well then someone has to die." This just makes me think about the disabilities hiding themselves (or unconscious masking to the best of their ability) in front of Doctors, like they're a vampire hiding from the sun.
"Once you chase me down the hole," or once you try and figure the disability out, "yeah once you think you're in control," when you've been able to manage it for a few weeks or months or even years, "you'll believe that we are partners and you'll feel uncomfortable." or the classic "was I really that bad or was I just being dramatic" feeling that comes with feeling too good for long periods of time.
"Oh then the darkness rolls in," a flare, or a bad day. "And you'll forget who I have been," how to manage it.
"The simple love that your grandparents had, this kind of love will only make you mad." Realising that finding a partner will also include making sure it's someone that is okay with being "with a disabled person" which is, for some reason, not something people are okay with. 🙄
"It hurts at first but it ain't that bad," the beginning tends to be the worst but once you understand your body and it's limits it's not hard to "deal with" (I can't think of another word for what I mean) anymore. "You gotta wonder what it meant."
Anyway, this got really long but relating love songs (I use the term loosely) to the relationship disabled/chronically ill people tend to have with their disabilities. So.... ¯\_(ツ)_/¯

A protein found in human sweat may protect against Lyme disease
New Post has been published on https://thedigitalinsider.com/a-protein-found-in-human-sweat-may-protect-against-lyme-disease/
A protein found in human sweat may protect against Lyme disease
Tumblr media Tumblr media
Lyme disease, a bacterial infection transmitted by ticks, affects nearly half a million people in the United States every year. In most cases, antibiotics effectively clear the infection, but for some patients, symptoms linger for months or years.
Researchers at MIT and the University of Helsinki have now discovered that human sweat contains a protein that can protect against Lyme disease. They also found that about one-third of the population carries a genetic variant of this protein that is associated with Lyme disease in genome-wide association studies.
It’s unknown exactly how the protein inhibits the growth of the bacteria that cause Lyme disease, but the researchers hope to harness the protein’s protective abilities to create skin creams that could help prevent the disease, or to treat infections that don’t respond to antibiotics.
“This protein may provide some protection from Lyme disease, and we think there are real implications here for a preventative and possibly a therapeutic based on this protein,” says Michal Caspi Tal, a principal research scientist in MIT’s Department of Biological Engineering and one of the senior authors of the new study.
Hanna Ollila, a senior researcher at the Institute for Molecular Medicine at the University of Helsinki and a researcher at the Broad Institute of MIT and Harvard, is also a senior author of the paper, which appears today in Nature Communications. The paper’s lead author is Satu Strausz, a postdoc at the Institute for Molecular Medicine at the University of Helsinki.
A surprising link
Lyme disease is most often caused by a bacterium called Borrelia burgdorferi. In the United States, this bacterium is spread by ticks that are carried by mice, deer, and other animals. Symptoms include fever, headache, fatigue, and a distinctive bulls-eye rash.
Most patients receive doxycycline, an antibiotic that usually clears up the infection. In some patients, however, symptoms such as fatigue, memory problems, sleep disruption, and body aches can persist for months or years.
Tal and Ollila, who were postdocs together at Stanford University, began this study a few years ago in hopes of finding genetic markers of susceptibility to Lyme disease. To that end, they decided to run a genome-wide association study (GWAS) on a Finnish dataset that contains genome sequences for 410,000 people, along with detailed information on their medical histories.
This dataset includes about 7,000 people who had been diagnosed with Lyme disease, allowing the researchers to look for genetic variants that were more frequently found in people who had had Lyme disease, compared with those who hadn’t.
This analysis revealed three hits, including two found in immune molecules that had been previously linked with Lyme disease. However, their third hit was a complete surprise — a secretoglobin called SCGB1D2.
Secretoglobins are a family of proteins found in tissues that line the lungs and other organs, where they play a role in immune responses to infection. The researchers discovered that this particular secretoglobin is produced primarily by cells in the sweat glands.
To find out how this protein might influence Lyme disease, the researchers created normal and mutated versions of SCGB1D2 and exposed them to Borrelia burgdorferi grown in the lab. They found that the normal version of the protein significantly inhibited the growth of Borrelia burgdorferi. However, when they exposed bacteria to the mutated version, twice as much protein was required to suppress bacterial growth.
The researchers then exposed bacteria to either the normal or mutated variant of SCGB1D2 and injected them into mice. Mice injected with the bacteria exposed to the mutant protein became infected with Lyme disease, but mice injected with bacteria exposed to the normal version of SCGB1D2 did not.
“In the paper we show they stayed healthy until day 10, but we followed the mice for over a month, and they never got infected. This wasn’t a delay, this was a full stop. That was really exciting,” Tal says.
Preventing infection
After the MIT and University of Helsinki researchers posted their initial findings on a preprint server, researchers in Estonia replicated the results of the genome-wide association study, using data from the Estonian Biobank. These data, from about 210,000 people, including 18,000 with Lyme disease, were later added to the final Nature Communications study.
The researchers aren’t sure yet how SCGB1D2 inhibits bacterial growth, or why the variant is less effective. However, they did find that the variant causes a shift from the amino acid proline to leucine, which may interfere with the formation of a helix found in the normal version.
They now plan to investigate whether applying the protein to the skin of mice, which do not naturally produce SCGB1D2, could prevent them from being infected by Borrelia burgdorferi. They also plan to explore the protein’s potential as a treatment for infections that don’t respond to antibiotics.
“We have fantastic antibiotics that work for 90 percent of people, but in the 40 years we’ve known about Lyme disease, we have not budged that,” Tal says. “Ten percent of people don’t recover after having antibiotics, and there’s no treatment for them.”
“This finding opens the door to a completely new approach to preventing Lyme disease in the first place, and it will be interesting to see if it could be useful for preventing other types of skin infections too,” says Kara Spiller, a professor of biomedical innovation in the School of Biomedical Engineering at Drexel University, who was not involved in the study.
The researchers note that people who have the protective version of SCGB1D2 can still develop Lyme disease, and they should not assume that they won’t. One factor that may play a role is whether the person happens to be sweating when they’re bitten by a tick carrying Borrelia burgdorferi.
SCGB1D2 is just one of 11 secretoglobin proteins produced by the human body, and Tal also plans to study what some of those other secretoglobins may be doing in the body, especially in the lungs, where many of them are found.
“The thing I’m most excited about is this idea that secretoglobins might be a class of antimicrobial proteins that we haven’t thought about. As immunologists, we talk nonstop about immunoglobulins, but I had never heard of a secretoglobin before this popped up in our GWAS study. This is why it’s so fun for me now. I want to know what they all do,” she says.
The research was funded, in part, by Emily and Malcolm Fairbairn, the Instrumentarium Science Foundation, the Academy of Finland, the Finnish Medical Foundation, the Younger Family, and the Bay Area Lyme Foundation.

genuinely did not realize there were so many in-game gaster enjoyers out there… obviously there’s always been a ton of affection for him in like a meme/headcanon sense even in the days of very early undertale fandom, but i feel like i never see anyone talking about the in-game dude except in a strictly lore context. i’ve never seen anyone just lay out a character analysis or whatever. im glad im not as crazy as i thought lol

Cycle counting and damage accumulation calculation for fatigue analysis of race car components
Assuming a lap and the most critical situation at this one, it is possible to evaluate the fatigue stress and safety factor for many components of a race car. Some of them is not so complex, as the wheel hub, but components as the uprigh requires another technique Actually, when the number of cycles can not be precisely defined, the it is possible estimate through the variable amplitude loading…

i can’t believe LL fandom had to go over the “LL team wrote Sage’s response to everything that happened in the timeskip rather realistically and it’s unfair to his character to throw fits about a traumatized person not being the same person you once fell in love with” conversation just so that today i have to read “i wish sage comes back; the real sage not the timeskip sage” with my own eyes

oh BTW my cursed seminar instructor did not reply to my email abt presentation topics and instead sent out a mail to all of us saying he doesn't have time to reply to individual emails and we need to go see him during office hours 🙄🙄 now i need to wait until next friday to do that so i think i will choose one of the two topics i had in mind and get started on research and then just clarify the thesis with him.
