Big Day, Huh?

Request from anon: Can you do a Spencer daughter reader where she has autism, like she always needs his help (can she be young like kid age)?

Spencer Reid x daughter!reader (child)

Summary: Spencer's autistic daughter has an eventful morning at the BAU.

A/N: Thank you for the request! I've never written a young child before so I hope this is okay.

CW: autistic reader going non verbal, eating habits, overwhelmed

---

You sat under your dad's desk, off in your own little world, as you tried to take apart one of his pens in a manner that would let you put it back together.

You had the day off school, but your usual nanny was away on vacation so you got to spend the day with your dad at the office.

You took the metro every day with him to get you to school, but the ride to Quantico was about twice as long as your ride to school. Spencer had told you that ahead of time so you could keep track on your wrist watch. He was thankful that watching the clock go by had kept you occupied and calm at the same time. When your normal schedule was disrupted you didn't like it, but making things as predictable as possible in unpredictable situations helped you cope.

Just like your dad, you liked numbers. He told you how many metro stops it would be (12), how many blocks you'd have to walk (3), how many security checks you'd go through (2- the metal detector for you and a search of your bag), and how many floors the elevator old climb (6) to get to the BAU.

The bullpen was already busy by the time the two of you arrived, Spencer holding your hand so you stayed close. To get away from the busy visual of the office, you'd found refuge under his desk.

“You can tap my knee if you need anything, okay?”

Too overwhelmed to speak, you nodded in response. He helped you pull out your noise canceling headphones and then one of your stuffed animals- the kind with beads in it so you could play with the way the weight changed depending on how you placed it. You started with balancing it on your head, and then in your hand, and eventually your dad's shoe.

At the time that you would normally switch from reading time to math class you had asked your dad for something new to do.

“What about this puzzle?” He pulled a small sliding puzzle from your bag.

“No. Teacher gives us things not from our bag to do.”

Spencer hadn't considered this before, but it was true. During reading time you got something from your bag and during math time the teacher gave you handouts. So he'd given you a sheet of paper with some simple equations and a pen, purposefully making the problems easy so you wouldn't get frustrated.

After you had “turned in your work” your dad let you keep the pen. You'd always liked to take things apart and then put them back together and pens were no different. Spencer secretly hoped one day it would be something more cool, like a spectroscopy machine or a space shuttle, but pens were a good place to start.

Once you had taken the cap off the top, the spring easily fell out and then the ink. You were careful to line each of the pieces up on the floor to keep them orderly. Once you put the pen back together you clicked it a few times just to make sure it was working correctly before starting the process over again.

You checked your watch- it was nearly time for lunch. You tapped your dad on the knee. He scooted his chair back so he could look at you under the desk.

“Hey, what is it?” he asked.

“It’s lunch time,” you told him.

Spencer thought quickly- technically his lunch break wasn’t for another two hours, but it wasn’t worth waiting if it meant you’d have a stomach ache later which could possibly lead to a meltdown.

“Okay,” he said. “Let’s go eat lunch.”

You took your lunch box out of your bag and crawled out from underneath the desk. It was even busier now than it was this morning. You started to grind your teeth and clench your fists, feeling something you couldn’t quite pinpoint boil inside you. Your dad noticed immediately.

“(Y/N),” he cooed. “Can I carry you to the lunch room?”

You nodded and Spencer picked you up. As soon as you were in his arms, he wrapped his limbs around you tightly, providing you with a calming pressure. You buried your head in his shoulder and closed your eyes, reducing the amount of visual input your brain was receiving. The familiar smell of your dad’s shirt was calming and you balled your fists in the fabric, holding onto him tight as he carried you to the conference room.

Once the two of you were inside, he shut the door. Unless there was a case, the room would be empty other than the two of you. He helped you climb up into one of the chairs and unpack your lunch. You ate the same thing every day- a bag of apple slices, a peanut butter and jelly sandwich with the crust cut off, banana chips, and some crackers. Everything was perfectly portioned as always. You ate each of them one at a time, never switching between foods but always finishing one before starting on another.

Spencer worked on files as you ate, keeping any crime scene photos carefully concealed from your line of vision. He knew after this it would be your normal rest time, and since change always made you tired, he hoped you might even take a nap.

Once you were finished eating, Spencer helped you clean up your lunch area. He closed up the files he was working on and thought about where you could possibly have rest time. You asked him to carry you back through the bullpen, to which he gladly obliged, and put your lunchbox away in your bag.

You yawned, clearly tired and a bit overwhelmed. “Rest time,” you told your dad.

“Do you want me to carry you again?” he asked.

You lifted your arms towards him, asking to be picked up. He carried you down the hall towards JJ’s office. There was a large leather chair in the corner of her office that you could curl up in for a little while, but by the time he reached her office door, you were already fast asleep in his arms.

“JJ?” Spencer said softly so he didn’t wake you.

“Hey, Spence,” JJ replied. She smiled when she saw you asleep in his arms. “Big day, huh?”

“Yeah,” he said. “Do you mind if we sit in the chair for a little bit? Just so she can get some rest?”

“Of course. Make yourself at home.”

Spencer walked over to the chair and sat down on it carefully. You stirred a bit in his arms but didn’t wake up. JJ closed the door to reduce the amount of sound in the room. Spencer kept you cradled in his grasp, feeling the softness of your breath against his shoulder and the gentle rise and fall of your tiny diaphragm against his body.

“You’re a great dad, Spence,” JJ told him. “She’s lucky to have you.”

Spencer smiled a bit. “She’s the best thing that ever happened to me.”

He began to feel himself relax. You were in a deep sleep now and the room was quiet other than the soft scratching of JJ’s pen against paper. He closed his eyes, telling himself that it would only be a minute, but before he knew it he was asleep too.

I was researching a small old ghost town that was situated on the same spot as the neighborhood I grew up in. I didn't know about it when I lived there. Even now it's still a very rural neighborhood of a dozen or so houses, next to what is now a 7-mile-long man-made lake and still surrounded by a lot of woods. I've been researching for several years with not much luck but I recently found an old hand-drawn map of the village online, drawn by a man who was born and lived there. My friend and I want to go and search for artifacts where the church, the store, the Post Office, and the blacksmith once stood. Those lots are vacant and have been since the original buildings were demolished in the very early 1900's, so they've sat undisturbed since then. We're going to take a metal detector and see if we can find any artifacts.

While researching and comparing that map to current google maps to pinpoint things, I was using terrain view and I noticed an odd formation on a ridge in the woods less than half a mile away. It's a perfect circular dome, with a sort of "tail" on it. Looks almost like a tadpole. There's no reason for it to be there - it doesn't look like normal erosion. It occurred to me it might be a Native American mound.

So all week I've been researching to find out what tribes, if any, used to be in that area and there WAS a settlement just 1.5 miles to the east of the mound. Holy crap I might really have found something! Then I found a map of the main NA trails in that county and it's right along the main trail in that area. 😮 I didn't know about any of that when I first thought it might be a NA mound - it all bolsters my theory, though.

We're going to go check it out. See what it looks like. Measure it. Maybe dig a little around it (not the mound itself, just the ground surrounding it) to see if we can find artifacts, which would be even more support for my theory. Then, if we still think it's a likely mound, I have to find an archaeologist or someone to report it to who would be able to determine if that's what it is.

This is so fun, it's like a treasure hunt! The ghost town, the mound, all of it. I love looking for forgotten history in this region, I study old maps all the time looking at what used to be there. I'm now searching for other forgotten mounds and I found several mound-looking formations a couple of counties over. And it turns out those are on another main trail and within 1-2 miles of a group of known burial mound sites (those mounds have sadly been destroyed) and there was a settlement very nearby, too, so I'm psyched! I could be wrong about them but the trails and settlements and other mound sites back it up. How cool would it be if even one of these turns out to be an actual forgotten Native mound!

The Night's Jewel: Black Cat's Stolen Hearts by Jade Gretz

The alleyway stank of rain-soaked garbage. Neon signs from the nearby club, flickering and dying, painted the puddles in putrid hues of pink and green. Felicia Hardy, the infamous Black Cat, crouched on a rusty fire escape, studying the warehouse below.

Normally, a break-in this straightforward was beneath her. Jewels, priceless artworks – those were her game. But this warehouse held something different: the Quantum Shifter prototype. Dr. Heinrich Weiss, a fringe physicist with more theories than sense, claimed it could pinpoint and open doorways to parallel universes. He'd died mysteriously last week, and the prototype had vanished.

Black Cat wasn't interested in the whole multiverse theory. She was interested in the buyers: a shadowy consortium of international tech companies rumored to be dabbling in dangerous, lucrative, and utterly off-the-books research. If they wanted access to alternate dimensions, whatever was in those realities had to be more precious than diamonds.

She dropped down, as silent as her namesake. The warehouse was surprisingly lax on security, considering the tech inside. A few infrared lasers and a motion detector were child's play.

Within minutes, she was inside the lab. The scent of stale coffee and burnt electronics lingered in the air. She spotted the prototype instantly – a gleaming metal sphere resting amidst a tangle of wires on a workbench.

"Bingo," she whispered with a grin, reaching out.

Her fingers froze when a ghostly whisper echoed through the warehouse. "Intruder detected. Primary lockdown sequence activated."

The metal shutters slammed down over the windows, plunging the room into darkness. Red emergency lights flickered to life, painting the prototype in a hellish glow.

"Not my style," Felicia muttered, flicking on her infrared goggles.

Something was incredibly wrong. Doors didn't seal themselves. Ghostly voices didn't announce intruders. And Dr. Weiss had been a disorganized mess, not the type to build hyper-complex lockdown protocols.

The Quantum Shifter, however, pulsed with an o …(see the rest of the story at deviantart.com/jadegretzAI). For more supergirl, chun li, batgirl, tifa, lara croft, wonder woman, rogue and much more, please visit my page at www.deviantart.com/jadegretzai - Thanks for your support :)

Toonami Weekly Recap 06/24/2023

Dr. Stone: New World (Age of Exploration Arc) EP#39 (04) - Eyes of Science: The existence of Why-Man is heavily debated as he may be a new enemy. Senku immediately crafts Scientific Eyes, using glass coated in Sphalerite and the electricity channeling power of crystals he creates a rudimentary Cathode-ray tube television screen, which when connected to the radio tower becomes a radar/sonar to accurately pinpoint targets over vast distances, even underwater. Testing the sonar Chrome is astounded it can even find fish, a welcome bonus for the upcoming voyage. The next issue arises; an engine big enough for a ship will requires tonnes of iron. Surprisingly it is Chrome who solves the issue; using what he learned from Senku he connects an electromagnet to the radar and spontaneously reinvents the Metal detector. Locating an iron deposit in a cave mile from the village they begin mining with Senku declaring they have reached the Industrial Revolution. Senku uses a petrol by-product plus gravel to make Asphalt concrete, allowing iron to be driven from the mine to the river by a paved road where Ryusui then sails it to the village. Under Senku and Kaseki's expertise the Minecarts are designed to make mining the iron even easier.

Unicorn: Warriors Eternal EP#09 - A Love's Last Light: The Evil takes over the cosmic realm and traps the heroes within it as well, where they learn that the Evil intends to destroy time itself.

Nona the Ninth, Chapter 32

(Curious what I'm doing here? Read this post! For detail on The Locked Tomb coverage and the index, read this one!)

(Open tomb icon) In which someone goes full American Horror Story.

Nona is wrapped in one of the big black cloaks, and Pyrrha carries her out, with Paul supporting Crux, with Kiriona. Aiglamene leads them down passages, until they stop before a door, and Aiglamene turns off the lantern. Pyrrha asks if they have to go in blind, but Aiglamene says bad enough that anyone's going in besides the Reverend Daughter and her cavalier. Kiriona says the Daughter has no living cav anyway.

They open the door, and Nona is carried into a void of a cathedral cave, with a rock in front of a tunnel.

And standing before the rock—a lantern by one booted foot—was Crown. Nona’s eyes had been tricked by the light. It wasn’t Crown. It was someone exactly Crown’s height, someone with Crown’s face, but like someone had washed her in hot water and soaked the colour out—a Crown who gangled, without any of Crown’s lovely curvy softnesses or bignesses, a wretched white Crown.(1) A Crown with an arm that was all bones—metal-shod bones, real moving bones, with bony gold fingers holding a tiny pinpoint of orange light. Nona realised that it really was her arm; that it really was a cigarette.

Pyrrha steps forward, but her feet are caught by some "soft, jammy yellow" substance on the floor. So are Paul's. Kiriona asks how Ianthe got here before her. Ianthe says she didn't, she just looked for "any signs of God and slithered downward".(2) She advises the rest not to move, and puzzles over her assumptions about not-Cam until they say their name is Paul. Ianthe says she can respect the choice, but not admire it.(3)

Pyrrha asks if John sent Ianthe, but she ignores the question and asks who Pyrrha is, really. Pyrrha admits that Varun ate G1deon, she's just "his leftover cavalier parts." Ianthe asks if that's typical of Lyctors, and Pyrrha says, no. Ianthe is relieved and says no, John didn't send her.

Ianthe moves to stand before Kiriona, and they stare each other down. Kiriona asks if she really has to smoke in here, there are fire detectors. Ianthe rolls her eyes and stubs out the cig on her flesh hand, tossing the butt over her shoulder. She asks if they brought her sister, and Kiriona confirms, she's upstairs for the taking when they're done. The Sixth leaders are there too, but she's not sure if John will want them, or the rest of their House.

It had slowly dawned on Nona—by the look of everyone else caught in the yellow muck, it was dawning on them too—that this conversation was not being carried out in a way anyone had expected. Ianthe reached out—her sleeve fell away from her wrist—and Nona saw a strange fat bracelet ringing her bony wrist: a braided, hyper-coloured cord in shades that were somehow even uglier than the cords she had seen before—in her class—and on the wrist of— “Friendship bracelets,” she fairly shouted. “They’re wearing friendship bracelets.”(3)

Ianthe frees Kiriona from the sticky stuff, and they do a secret handshake. Paul asks if they can be freed to get into the Tomb or not. The stick extends to take Nona out of Pyrrha's arms and pull her over to Ianthe, who says she's just doing what she thinks "Harry" would want, to keep the Tomb closed, and asks what Kiriona thinks. Kiriona says she tries not to, and they laugh in genuine, friendly mirth.

Ianthe says it's good to see her, and Kiriona says, yeah, but, time to get this Tomb opened so they can get out of here. Ianthe is confused, but Kiriona draws her sword, and Ianthe returns the favour, calling her a "three-way double crosser." Kiriona says she hasn't double-crossed anyone, John sent her. Pyrrha and Ianthe express doubt on this account.

“No. He did,” said the corpse prince. “I didn’t sneak onto that ship for my health. Don’t you see? This is my chance. We go in there, we open up the Tomb, I take down whatever’s inside—Alecto, Annabel, I don’t care, whatever her name is—boom, we’re done. Dad won’t be immortal anymore, but he says he doesn’t care about that, and I believe him, Tridentarius … I’ll be his cavalier. I’m the First. Hell, I’m his child and heir. Isn’t this the neatest way? Are you going to help me, or not?”

Ianthe has withdrawn, disgusted, saying Kiriona can't really believe that. Kiriona says he's never recovered, and if they weren't around, she's not sure what he'd do. Ianthe says he'd drown his sorrows with "whatever or whoever comes to hand". She even saw Grand Admiral Sarpedon coming out of his room the other day.

Kiriona is mega grossed out, because Sarpedon looks so old, and John doesn't, and also because John's her father and she doesn't want to know about his affairs.Ianthe calls her all sorts of names and says the important part is, nobody's killing or releasing the thing inside the Tomb, and Kiriona isn't becoming John's new cav, and is this all just about Harrow after all? Kiriona gives her a dressing down in return, and they argue for some more paragraphs until Kiriona says John told her that, with her blood, with his blood, she was the only one who could do it.

“He loves her!” Ianthe howled. “John loves Alecto—John needs Alecto! Without that piece of goddamned fridge meat, he’s nothing—and we need to keep him that way!” The secret was told: the secret was out—the middle brain disappeared. Nona unravelled.

I won't relay the details of this one, there are too many, but Kiriona begs Harrow to keep it together, and Paul gives Pyrrha a signal, at which she shoots Ianthe, who just falls and rolls and screams. Pyrrha says she was saving that one for John, since she stole the Herald bullet from Wake. She asks if they can still save Nona, and Paul tells someone to open the door, now.

Kiriona lifts Nona's shoulders, Pyrrha has her hips. Pyrrha warns Paul to keep her arm in place as it tries to fall off. Paul has no problem rolling the rock away, and Crux warns of the traps, but Paul takes point on those, too.

Nona remembers being Alecto, walking down this corridor, with a promise from John that there was something pretty to show her.

Paul reports that the traps have been disabled already, and it was very tidy work. Nona blacks out, until she hears Kiriona urgently asking someone to take something, as Crux mourns, and someone doesn't need all of something, but needs to keep it wet.(5) Pyrrha says they need fresh thanergy to activate something.

John loved her. She was John’s cavalier. She loved John. For she so loved the world that she had given them John. For the world so loved John that she had been given. For John had so loved her that he had made her she. For John had loved the world.(6)

They argue, but Crux offers that they should take his life to do this.

(Another memory of Alecto entering this place, being bound with chains and ice.)

Crux says he's the only one who knows how to properly die for Harrow anyway. Kiriona, though in a new voice altogether,(7) says it's the only good he'd ever do Harrow, and the only thing any of the Ninth knew how to give her. Crux protests that Kiriona doesn't know what she's talking about, and Aiglamene forbids it outright, but Kiriona snarls that he wants to die, and she's wanted to do it for years.

(Another memory, John saying the thing is so beautiful, Alecto saying there are hardly any beautiful things left, and she'd like to talk to Anastasia.)

“Then do it, coward,” Crux said. “Do it—the knife is before you; the work has been done.” “Did you know I’m God’s child?” Kiriona demanded. “Did you know all the things you did—[...]—did you know I was the real, true-blue daughter of the Emperor? I want you to know that—I want you to know what I am!” “You remain—what you are,” said Crux. “A worthless millstone hung about my darling’s neck. You were born to make her suffer. You died as you lived, Gideon Nav—a disappointment to me—and to God.”(8) There was a wet, meaty sound. The old man exhaled. It was dark. Then there was light, bright, cold, electrifying, like death; and the noise of another rock—slowly—agonisingly—grinding away. And Kiriona kept saying— “It didn’t feel good … Fuck … It didn’t feel good. Why didn’t it feel good?” A rising, hysterical note. “Why didn’t it feel good? You fucking old … You hideous, cruel … you bastard … Why didn’t … Why can’t I…”(9) Glowworms, she had told John. Technically beetles, said John, but I always loved them.

Glowworms take up most of a paragraph as Harrow's body loses a foot, Paul jams it back on, and they come to the giant pool of saltwater(10) where she had knelt and taken a drink...

She moved the baby’s body apart from the others. They could not stop her. She stepped into the water: A-a-a-ah! That was good. The water was ice-cold—it froze the baby’s heart in its tracks—but she was moving her now and did not need her heart. Someone said, “Let her go. It’s gravity. Let her go,” and those voices were dim now—she could no longer distinguish them. Most human voices sounded alike, after all. They were not beautiful. The waters parted for her and it became possible to walk, crunching through the bones at the bottom. The bones at the bottom; what did they make her think of?

She and John had swum to the not quite island in the pool, he told her to lie down on the marble, and she had liked hard things to lay down on.

An echo down the tunnel, Ianthe, still screaming, drawing closer.

Alecto finds her body, just as John made it, so ugly.(11)

But there she was—and within her the child, asleep, with the strange sword.(12) The sword—her sword—her own edge had been pushed out, her swinging edge, her toy. Her plain bladed sword. And her body was chained up …

Someone howls defiance from the shore, but she looks up, sees Anastasia's skeleton, where she lay once, ready to close the door after it had opened.(13)

Her vision swam: her heart was in her throat. “Well, happy birthday to me, I guess,” sighed Nona. And Nona tumbled forward onto the icy dead breast of the Body.

=====

(1) The first person Nona hasn't thought was beautiful or at least interesting. The very first person she's ever seen and described in the text who's not beautiful and who she doesn't love instantly. And it's IANTHE! The wretched pale imitation of her sister. I cackled the first time and I'm giggling now. Also, my above-the-cut description is at this appearance. It's not exactly that AHS:Coven meme scene, but Ianthe would absolutely "Surprise, bitch" the fuck out of these pals. (2) Very evocative of the snake in the Garden of Eden. (3) We haven't had any indications that the modern Nine Houses use any form of the our-world Christian bible, but do you think Ianthe got crash courses from John, or did some reading in a Mithraeum library of some sort, to make this reference? Or, unexpected third (pun intended) option, do the Houses have their own stories about famous Pauls? (4) You may or may not recall that back in GtN, when Harrow had cocooned herself in the Facility, Gideon wondered if Harrow had been murdered, and if it would be awkward to be married to Harrow's murderer in gratitude, or if maybe they should just swap friendship bracelets instead. (5) Gotta have something for Harrow to come back to. (6) Hard to even pretend to attribute this to Nona at all. It also has a very biblical bent to the phrasing, doesn't it? (7) A new voice to Nona-Alecto. Possibly the same Gideon we knew in GtN. (8) How much of this is his genuine feeling? How much is that he knows he's dying, can probably feel that corrupted devil wound spreading, knows this is the last gift he can give the daughter he never had, or perhaps the girl who replaced the daughter he once actually had, who died to bring that miracle-abomination into the world. How much is him letting Kiriona have her vengeance if it will make her feel better? Do you think he'd still do it, knowing how she feels after, or would he have been gentler with her, like he was with young pre-Canaan Harrow? (I'm just gonna need a moment to weep before I continue, you wouldn't have noticed but I felt it worth noting.)

(9) (Oops, another weepy moment already, bear with.) John has been driven for ten thousand years to avenge someone he killed first, even if those he sought vengeance against would have done it eventually, and even if those decision makers are long, long gone. We don't know much about Wake or her life except that she had at least one sibling, at least one niece. But, I think it's fair to say that she was also driven to vengeance against the man who had been persecuting her and her ancestors for ten thousand years over an injustice that never happened and would have resolved itself almost that very long ago. But Kiriona, but our Gideon, is not her parents. She was raised in a love-hate environment, it's true, but that just means she is not the pure product of her genes. She is so much more than the sum of those parts. She puts on a front because she's been hurt so, so goddamn much, but she loves, maybe almost as much as Nona does, and her heart, her soul, her body know that vengeance isn't what she ever sought from Crux. She fantasized about killing him, even thought she regretted not doing so, but she did it because that was the only framework she'd ever been given to contextualize her feelings. I really think that this moment is setting her up for something special in AtN when she finally reckons with it all.

(10) I suspect the reason Harrow's family used a saltwater pool to share secrets ties back to this, the secret saltwater pool in the biggest half-secret of the Ninth House entire. (11) The only thing Nona-Alecto has described as ugly, as far as I can remember or tell? Is the toy-body John built without her asking, without her consent, without her input at all. His conception of beauty, such an ugly thing. (12) Harrow did have another place to escape to, when she didn't want to return her soul lest she hurt Gideon's chances. Alecto made that connection with her… and she made one back. At least, I think this is what this means, since the last time we saw Harrow, in the last chapter before the epilogue that properly belonged to Nona, she was in a coffin with Gideon's sword and titty mags. (13) Anastasia locked herself in the Tomb? John put Alecto to sleep, chained her. Why did Anastasia stay?

Eyes on Hera: Asteroid mission's cameras ready ESA's Hera asteroid mission for planetary defense is about to gain its sight. Two complete and fully tested Asteroid Framing Cameras have reached OHB in Germany for integration aboard Hera's payload module. This instrument will provide the very first star-like view of Hera's target for the mission to steer towards the Dimorphos asteroid, which last year had its orbit altered by an impact with NASA's DART mission. "It is a huge milestone to have the very first Hera payload ready for integration onto the spacecraft," says Hannah Goldberg, Hera system engineer. "And the Asteroid Framing Camera, AFC, is not only our first payload, but also the most important, since by itself it can obtain all the mission's core goals. Hera payloads are arranged with core and opportunity objectives in mind—based firstly on the data we have to acquire, then the secondary results we seek to obtain whenever possible. "Our October 2024 launch date is creeping ever closer, but the mission subsystems are beginning to come together as planned. So the next time we'll see these cameras will be aboard the complete Hera flight model when overall spacecraft testing begins this autumn." Hera is Europe's contribution to an international planetary defense experiment. Following the DART mission's impact with the Dimorphos asteroid last year—modifying its orbit and sending a plume of debris thousands of kilometers out into space—Hera will return to Dimorphos to perform a close-up survey of the crater left by DART. The mission will also measure Dimorphos' mass and make-up, along with that of the larger Didymos asteroid that Dimorphos orbits around. Operated on a redundant basis—meaning one unit will be kept in reserve in case of failure—the AFC will play a pivotal role in Hera's mission. As well as acquiring detailed views of the surface of Dimorphos for scientific analysis, including the crater left by the DART impact, the AFC will also be used for guidance, navigation and control. The AFC will home in on Dimorphos when it is still a single point of light in the sky—seen in conjunction with the larger asteroid Didymos. The AFC will then transition to close-up navigation, utilizing edge detection to keep the asteroid centered in its field of view while tracking surface features to derive Hera's exact position from the asteroid in a similar manner to self-driving car software. Around the same size and shape as a household vase, the 1.3 kg AFC has been designed, manufactured and tested by Jena-Optronik in Germany. The compact design with its long baffle to protect the camera's optics from sunglare shares heritage with the startracker units that Jena-Optronik specializes in—utilized to map the stars around a spacecraft in order to pinpoint its position in space. Steffen Schwarz, Head of Marketing & Sales at Jena-Optronik, comments: "Hera is a prestigious mission and we at Jena-Optronik are looking forward to make a decisive contribution to its success through our camera." Possessing a 5.5 degree field of view, the monochromatic AFC acquires images using complementary metal–oxide–semiconductor active pixel sensor (CMOS APS) technology—an advanced, rad-hardened version of the imaging used in modern smartphone cameras—the FaintStar2 detector chip marketed by Caeleste in Belgium, initially designed for startrackers through a project in ESA's General Support Technology Program. "The images we will see from the AFC will resemble those returned by DART before its impact," adds Hannah. "For example, the picture we saw of the two asteroids together in DART's field of view, and then later on the boulder-strewn surface of Dimorphos as DART was about to collide. "The AFC's images will be complemented by color images from other instruments, including Hera's HyperScout instrument which will see in 25 different colors and the ASPECT hyperspectral imager aboard the Milani CubeSat, whose vision will extend beyond visible light into the infrared." Other Hera subsystems are currently being finalized: Hera's laser-based PALT (Planetary Altimeter) coming from Portugal; the HyperScout2 imager from the Netherlands; the Milani CubeSat from Italy and the Juventas CubeSat from Luxembourg; and the TIRI thermal imager contributed by Japan. TOP IMAGE....The Asteroid Framing Camera, AFC, will play a pivotal role in Hera’s mission. As well as acquiring detailed views of the surface of Dimorphos for scientific analysis, including the crater left by the DART impact, the AFC will also be used for guidance, navigation and control. The AFC will home in on Dimorphos when it is still a single point of light in the sky – seen in conjunction with the larger asteroid Didymos. The AFC will then transition to close-up navigation, utilising edge detection to keep the asteroid centered in its field of view while tracking surface features to derive Hera’s exact position from the asteroid in a similar manner to self-driving car software. Around the same size and shape as a household vase, the 1.3 kg AFC has been designed, manufactured and tested by Jena-Optronik in Germany.

The Comprehensive Guide to Repairing Auto Air Conditioning Systems

In the scorching heat of summer or the biting cold of winter, a functioning air conditioning system in your vehicle can be a saving grace. However, like all mechanical components, auto air conditioning systems are susceptible to wear and tear, leaving you sweating or shivering on your daily commute. Fear not! This comprehensive guide will walk you through everything you need to know about repairing auto air conditioning systems, from identifying common issues to troubleshooting and performing repairs yourself.

Understanding Auto Air Conditioning Systems:

Before delving into repairs, it's crucial to understand how Repair Auto Air Conditioning systems work. Most modern vehicles utilize a closed-loop system that circulates refrigerant to absorb and dissipate heat, providing cool air inside the cabin. The main components include the compressor, condenser, evaporator, and expansion valve or orifice tube. Refrigerant flows through these components, undergoing phase changes to transfer heat effectively. Familiarizing yourself with these components will aid in diagnosing and repairing issues.

Identifying Common Issues:

When your car's air conditioning system malfunctions, it's often due to one of several common issues. These can include refrigerant leaks, compressor failure, clogged condenser or evaporator, electrical problems, or issues with the cooling fans. Symptoms may manifest as weak airflow, warm air blowing from vents, strange noises from the compressor, or visible leaks under the vehicle. Identifying these symptoms early can prevent further damage and costly repairs down the road.

Diagnosing the Problem:

Diagnosing air conditioning issues requires a systematic approach. Begin by inspecting visible components for leaks or damage. Next, use a manifold gauge set to measure refrigerant pressure and ensure it falls within the manufacturer's specifications. If pressure is low, it may indicate a leak or compressor failure. Electrical issues can be diagnosed using a multimeter to test components for continuity and proper voltage. Additionally, specialized tools such as UV dye kits or electronic leak detectors can pinpoint elusive refrigerant leaks.

Repairing Refrigerant Leaks:

Refrigerant leaks are a common culprit behind malfunctioning air conditioning systems. Once you've identified the leak, repair methods vary depending on its location and severity. Small leaks in hoses or connections can often be fixed using rubber O-rings or replacement fittings. Larger leaks may require welding or soldering of metal components. After repairs are complete, it's essential to evacuate and recharge the system with the correct amount of refrigerant to ensure optimal performance.

Compressor Replacement:

If your compressor fails, it's a critical component that must be replaced to restore cooling functionality. Symptoms of compressor failure include loud noises, clutch slippage, or a lack of cold air despite proper refrigerant levels. Compressor replacement involves draining the refrigerant, removing the old compressor, and installing a new one. It's also advisable to replace other components such as the receiver-dryer or accumulator and orifice tube to prevent contamination and ensure system longevity.

Cleaning and Maintenance:

Regular maintenance is key to preventing air conditioning issues. Keep the condenser and evaporator clean by removing debris such as leaves, bugs, and dirt that can restrict airflow and hinder heat transfer. Check refrigerant levels annually and top up if necessary to prevent system inefficiency. Additionally, inspect hoses, connections, and seals for signs of wear or damage and replace as needed to prevent leaks.

Seeking Professional Help:

While DIY repairs can save you money, some air conditioning issues may require professional expertise. If you're unsure about diagnosing or repairing a problem, it's best to consult a certified technician. They have the tools, knowledge, and experience to accurately diagnose issues and perform repairs safely. Moreover, professional repairs often come with warranties, providing peace of mind knowing the job is done right.

Conclusion:

A malfunctioning auto air conditioning system can turn a comfortable drive into a miserable experience, especially during extreme weather conditions. However, with the knowledge gained from this guide, you're equipped to tackle common issues and perform basic repairs yourself. Remember to prioritize safety and follow manufacturer guidelines when working on your vehicle's air conditioning system. By staying proactive with maintenance and addressing issues promptly, you can ensure your car's air conditioning keeps you cool and comfortable mile after mile.

With inspiration from “Tetris,” MIT researchers develop a better radiation detector

New Post has been published on https://sunalei.org/news/with-inspiration-from-tetris-mit-researchers-develop-a-better-radiation-detector/

With inspiration from “Tetris,” MIT researchers develop a better radiation detector

The spread of radioactive isotopes from the Fukushima Daiichi Nuclear Power Plant in Japan in 2011 and the ongoing threat of a possible release of radiation from the Zaporizhzhia nuclear complex in the Ukrainian war zone have underscored the need for effective and reliable ways of detecting and monitoring radioactive isotopes. Less dramatically, everyday operations of nuclear reactors, mining and processing of uranium into fuel rods, and the disposal of spent nuclear fuel also require monitoring of radioisotope release.

Now, researchers at MIT and the Lawrence Berkeley National Laboratory (LBNL) have come up with a computational basis for designing very simple, streamlined versions of sensor setups that can pinpoint the direction of a distributed source of radiation. They also demonstrated that by moving that sensor around to get multiple readings, they can pinpoint the physical location of the source. The inspiration for their clever innovation came from a surprising source: the popular computer game “Tetris.”

The team’s findings, which could likely be generalized to detectors for other kinds of radiation, are described in a paper published in Nature Communications, by MIT professors Mingda Li, Lin-Wen Hu, Benoit Forget, and Gordon Kohse; graduate students Ryotaro Okabe and Shangjie Xue; research scientist Jayson Vavrek SM ’16, PhD ’19 at LBNL; and a number of others at MIT and Lawrence Berkeley.

Radiation is usually detected using semiconductor materials, such as cadmium zinc telluride, that produce an electrical response when struck by high-energy radiation such as gamma rays. But because radiation penetrates so readily through matter, it’s difficult to determine the direction that signal came from with simple counting. Geiger counters, for example, simply provide a click sound when receiving radiation, without resolving the energy or type, so finding a source requires moving around to try to find the maximum sound, similarly to how handheld metal detectors work. The process requires the user to move closer to the source of radiation, which can add risk.

To provide directional information from a stationary device without getting too close, researchers use an array of detector grids along with another grid called a mask, which imprints a pattern on the array that differs depending on the direction of the source. An algorithm interprets the different timings and intensities of signals received by each separate detector or pixel. This often leads to a complex design of detectors.

Typical detector arrays for sensing the direction of radiation sources are large and expensive and include at least 100 pixels in a 10 by 10 array. However, the group found that using as few as four pixels arranged in the tetromino shapes of the figures in the “Tetris” game can come close to matching the accuracy of the large, expensive systems. The key is proper computerized reconstruction of the angles of arrival of the rays, based on the times each sensor detects the signal and the relative intensity each one detects, as reconstructed through an AI-guided study of simulated systems.

Of the different configurations of four pixels the researchers tried — square, or S-, J- or T-shaped — they found through repeated experiments that the most precise results were provided by the S-shaped array. This array gave directional readings that were accurate to within about 1 degree, but all three of the irregular shapes performed better than the square. This approach, Li says, “was literally inspired by ‘Tetris.’”

Key to making the system work is placing an insulating material such as a lead sheet between the pixels to increase the contrast between radiation readings coming into the detector from different directions. The lead between the pixels in these simplified arrays serves the same function as the more elaborate shadow masks used in the larger-array systems. Less symmetrical arrangements, the team found, provide more useful information from a small array, explains Okabe, who is the lead author of the work.

“The merit of using a small detector is in terms of engineering costs,” he says. Not only are the individual detector elements expensive, typically made of cadmium-zinc-telluride, or CZT, but all of the interconnections carrying information from those pixels also become much more complex. “The smaller and simpler the detector is, the better it is in terms of applications,” adds Li.

While there have been other versions of simplified arrays for radiation detection, many are only effective if the radiation is coming from a single localized source. They can be confused by multiple sources or those that are spread out in space, while the “Tetris”-based version can handle these situations well, adds Xue, co-lead author of the work.

In a single-blind field test at the Berkeley Lab with a real cesium radiation source, led by Vavrek, where the researchers at MIT did not know the ground-truth source location, a test device was performed with high accuracy in finding the direction and distance to the source.

“Radiation mapping is of utmost importance to the nuclear industry, as it can help rapidly locate sources of radiation and keep everyone safe,” says co-author Forget, an MIT professor of nuclear engineering and head of the Department of Nuclear Science and Engineering.

Vavrek, another co-lead-author, says that while in their study they focused on gamma-ray sources, he believes the computational tools they developed to extract directional information from the limited number of pixels are “much, much more general.” It isn’t restricted to certain wavelengths, it can also be used for neutrons, or even other forms of light, ultraviolet light, adds Hu, a senior scientist at MIT Nuclear Reactor Lab.

Nick Mann, a scientist with the Defense Systems branch at the Idaho National Laboratory, says, “This work is critical to the U.S. response community and the ever-increasing threat of a radiological incident or accident.”

Additional research team members include Ryan Pavlovsky, Victor Negut, Brian Quiter, and Joshua Cates at Lawrence Berkely National Laboratory, and Jiankai Yu, Tongtong Liu, Stephanie Jegelka at MIT. The work was supported by the U.S. Department of Energy.
