Icosidodecahedron and truncated icosidodecahedron - with orange and green lines and red and green filters layered on top to filter out one of the solids

That is the drawing with both polyhedra included:

The orange lines depict the icosidodecahedron.

The green lines depict the truncated icosidodecahedron.

Putting a green translucent sheet of foil on top (green filter) filters out the green. The orange stays visible. Hence: With the green filter you mainly see the icosidodecahedron.

Putting a red filter instead filters out the orange and the green stays visible. Hence: With the red filter only the truncated icosidodecahedron is visible.

- - -- ---

For drawing the icosidodecahedron I started with drawing a regular dodecahedron and "cut off" the vertices to half of each edge.

For drawing the truncated icosidodecahedron I started with an icosidodecahedron and cut off the vertices to one third of each edge.

Webinar on High Performance RF Filters in a Photonic Chip.

Photonic integration brings the promise of significant cost, power and space savings and propels the real applications of microwave photonic technology. In this paper, a multiband radio frequency (RF) signal simultaneous receiver using an optical bandpass filter (OBPF) integrated with a photodetector (PD) on a chip is proposed, which was experimentally demonstrated. The OBPF was composed of ring-assisted Mach–Zehnder interferometer with a periodical bandpass response featuring a box-like spectral shape. The OBPF was connected to a PD and then integrated on to a single silicon photonic chip. Phase-modulated multiband RF signals transmitted from different locations were inputted into the OBPF, by which one RF sideband was filtered out and the phase modulation to intensity modulation conversion was realized. The single sideband with carrier signals were then simultaneously detected by the PD. A proof-of-concept experiment with the silicon photonic integrated chip was implemented to simultaneously receive four channels of 8 GHz, 12 GHz, 14 GHz and 18 GHz in the X- and Ku-bands. The performance of the integrated microwave photonic multiband receiver—including the receiving sensitivity, the spurious free dynamic range, the gain and the noise figure across the whole operation frequency band—was characterized in detail.

i was saving up for a tattoo but ur answer to that ask where u mention the stuff that goes into ink made me go down a rabbit hole and now i think i wont be getting a tattoo until ink is regulated... aside from the ink being full of stuff i know im allergic to my family is very cancer prone and im reading that tattoo ink may have a correlation with increased skin cancer risk. i feel like this should be talked about more. feeling sad about it but im glad u mentioned something about it otherwise i wouldnt have known

Yeah, as someone who's allergic to everything, has eczema, and a family history of cancer, I feel that. If you have a good artist whom is open to using inks that are either carcinogen-free or at least better tolerated it's not the end of the world, and I never want to discourage someone from doing something they want to do, especially art-related! That being said, I had some similar asks so I'm gonna use yours as a quick info-dump, so I apologize in advance!

I do want to be VERY clear: this is NOT a 'tattoos bad' wall of text, it's a 'art good but hold businesses and individuals accountable because right now everything is a trust system' wall of text. Everyone I know and love has tattoos, I just happen to be an artist who was pulled into the industry fairly out-of-the-blue 8 years ago, and have gotten to learn the intimate ins-and-outs of it because of that. This isn't ragebait, and it is strictly my reasons as to why I feel that the industry could benefit from some regulation and standardized education now that it is a very, very mainstream industry that the majority of individuals in my age range engage with but aren't privy to the details on. If you love tattoos, great! If you don't love tattoos, great! If you're an experienced professional in the industry, this is all stuff you've probably bounced off of once or twice, and can understand why it's frustrating.

The tattoo industry sorta has had one foot in the super lax, counterculture boat while also having the other one solidly in the corporate, capitalist yacht. While the studies that come out of the industry relating cancer risk to the ink content always stick strictly to skin cancer risk being 'negligible', it's important to note that the ink isn't going into your skin - it's going into the fatty tissue below the skin. The ink breaks down in that tissue over time, and gets filtered out by your body - the contents of the ink aren't on the top of the skin, they're being filtered through your other organs or pushed up to your skin. (I know this is an ultra-super-simplified version of what happens, but I don't want to give everyone a migraine with details.) I work with a ton of inks, paints, and pigments, and the pigments that are used in some inks aren't stuff I'd willingly handle with my bare hands, but I'm paranoid about that stuff. However,I absolutely wouldn't eat any of the pigments that are used in the creation of the ink used for tattoos, and none of it is stuff that I'd want in my liver or kidneys. I have a parent who's had cancer for 10+ years, so it's a pet topic of mine that I've had the opportunity to discuss with professionals whom work in the industry. The few times I've gotten to chat about inks used in tattoos, the response is the same as the public PR team's response. The standard on-record response is to cite skin cancer risks, and when asked about other types of cancer, specifically liver/kidney/reproductive, often it is deflected to some version of 'our customers are risk takers who live life on the edge, and don't conform to societal norms, and that demographic always has a higher rate of cancer.' The reality is that they intentionally don't test for that, because best case is the optics that they were selling something that they weren't that confident in, and the worst case response is a wall of lawsuits. Obviously, all that sounds ominous and shit, and while I doubt there's anything massive hidden there, my problem is that the corporate side regulates itself, which in the history of everything has never ended in ethical decisions and only ones that increase profit margins. When pressured, however, companies will lean into the 'it's tattoos man, don't be a downer' - but these are large, industrial corporations, not the dude down the street making art out of their garage. They have the money to test their own products and choose not to.

The other half of the problem is that foot in the pseudo-counterculture, lax, independent artist culture. There's no barriers to entry, minimal qualifications required, and so you can have people who have no business putting permanent ink on folks doing just that, en masse. Tattoos became a major fashion thing in the last 10 years, so we saw an explosion of tattoo studios with literally no experience in the industry kicking out tattoos. These same folks don't have experience in the arts (in a lot of cases) so they'll lift someone else's work as theirs to get a sale, which leads to someone having a design that may be associated with a group they do not wish to be associated with (IE: ultra-nationalist found out that his reaper design was from some ACAB shit I made, and he was not thrilled, even though I thought it was hilarious.) Additionally, a lot of the more questionable studios engage in super controversial sales tactics pressuring clients to move forward on projects when they aren't 100% comfortable (ie: you don't get to see the tattoo until you're in the chair, strictly to save time as to maximize profit on a permanent work of art, and to avoid your client changing their mind.) Back when I was starting out, a lot of the freelance work I received was coming up with designs to help fix those botched jobs, while sending folks to a credible artist, so I had the unfortunate experience of hearing every nightmare story ever. However, like any market that was opening up to big mainstream cashflow, the market ended up flooded so the skill of the average tattoo artist fell like a brick. Only in the last 6 months has the bubble popped with a ton of studios have had trouble staying afloat because the industry reached critical mass. I literally have more options in tattoo studio within a 10 block radius than grocery stores. Mind you, I'm talking about the large group of studios that engage with these practices, and that does in no way mean that I am specifically talking about your studio or your artist. If you work in the industry, you know the folks I'm talking about, and I'm so sorry they make your job so much harder.

This all comes together into a major shitstorm: under-qualified individuals offering a subpar product driving down prices, shoving out the actual qualified professionals, while operating in a legal gray area. Combined with the industrial ink companies that aren't keen on giving straight answers about the contents of their product leaves the entire industry in an absolutely dogwater spot, getting the worst of both worlds. This is not touching on the disgusting potential abuse of power that some individuals choose to take advantage of within these situations. With literally any small amount of regulation, the entire art form would be infinitely easier to get for individuals without having to do a background check on the entire operation. I hope that answers some questions, and I apologize for any typos in my incomprehensible wall of text!

So what about, Cybertronians react to perfume in the way humans react to Sex pollen hehehe. I love the idea of human perfume mix with skin contact makes an almost intoxicating scent and sends Cybertronians feral when they get a hint of it. They love how it makes humans skin taste, and it over rides their interface systems.

So enjoy.

_____________

The human moves around Ratchet's medical lab looking at different vials and flasks their eyes flickering over the difference Liquids. " Hey ratchet what are all of these different vials?" They call out to the medic. Ratchet looked up from his work when he heard the human call out to him. He put down the datapad he was looking over and walked over to where the human was examining the various vials on the shelves.

"Those are different medical compounds and chemicals I use in treatments and repairs," Ratchet explained. "The colourful ones contain powerful medications and sedatives. The clear ones hold things like bonding agents or nanite solutions. Others are a mix of experimental solutions" 

He pointed to a vial with a swirling pink and purple liquid. "That one is a broad-spectrum energon healing compound I developed. It speeds cellular repair and regeneration, within Cybertronian functions." His optical ridges furrowed as he watched the human carefully look over each vial. 

"You know better than to touch anything in here, less you break something and contaminate yourself with something i can't fix" Ratchet said sternly. "Some of this equipment and chemicals could seriously harm an organic being like yourself." Despite his gruff tone, his words held more care than scolding. Biology was complex, and humans were so small and fragile compared to Cybertronians. He hoped his favourite little patient and helping hand was being careful not to endanger themselves.

"It's just fascinating is all, kinda reminds me of a mediaeval apothecary" they chuckle. "Do you ever just take samples for fun, like when you're out and about on planets?" They ask, they were always curious over what things ratchet tended to keep.

Ratchet huffed a small laugh at the comparison to a mediaeval apothecary. "Fascinating perhaps, but also dangerous if mishandled," he remarked.

He considered the human's question for a moment. While most of his samples were acquired for medical necessity, he couldn't deny a certain curiosity about other life forms and ecosystems. 

"On occasion I have collected specimens from planets we've visited, simply for observational study," Ratchet admitted.  He walked over to retrieve a data pad containing photos and analyses of plant samples from their recent away missions. "Here, let me show you some I recorded on our last stop." Ratchet enlarged the images for the human to easily see. "This radiation-resistant lichen seems to secrete a natural antifreeze. And these fungi act as natural air filters in their toxic environment." The medic's optics glinted with interest as he discussed his findings. Perhaps exploration held some appeal, even for a skeptic like himself.

They stand close to Ratchet looking over different specimens, “some of these plants look like they would make really nice perfumes'' they mumble while flicking through the different photos reading the small information bubbles around them. As the human stood near Ratchet examining the data on his specimens, something about their scent suddenly registered in his olfactory sensors. An overly sweet aroma was emanating strongly from their skin, but it was clearly not the normal scent of an unadulterated human.“perfume?forgive me, I'm not accustomed to what that is?” he asked with a raised optical ridge

Their eyes flicker to Ratchet. “It's like scented alcohol or oil we put on our skin, most times it alters our scent. We humans happen to have a big fascination with them, and have millions of different perfumes.” they explain before tilting their head in slight amusement. “I'm surprised Cybertronians don't have something similar” they reply. 

“once millennia's back cybertron did try making things like that, but due to our metallic body's it doesn't stay on us, or it tented to cause rust spots from the ones they did try and make” Ratchet explained, sensors flared as he analysed the unfamiliar composition, immediately detecting unusual chemical traces that seemed to send strange pulses through his neurocircuitry. The smell was strangely enticing yet worryingly off-kilter at the same time. He tried venting deeply to clear his nasal chamber but the scent only grew stronger. 

"What in the Allspark..." the medic muttered, not meaning for the human to hear. His optics dimmed slightly as redundant calibrations ran, trying to make sense of why the scent was affecting his processor. Ratchet crouched down and focused his sharp gaze on the human in concern. They smile up at him offering for him to examine. 

"By my scanner  it seems as if you've been contaminated with something. Are you positive these ‘perfumes’ are safe? I need to analyse your system for potential toxins." He asked while trying to figure out why the scent was having such an effect on him, it was as if his processor had thrown care to the wind. 

They let out a laugh as his optics try analysing, he moves closer taking another inhale of their scent "haha yes Ratchet, it isn't harmful, humans have been using it for hundreds of years" they state. “Ratchet are you alright?” They ask while cupping his face. 

Ratchet's sensors were in disarray as the potent scent overwhelmed his circuits. He vented heavily again, coolant failing to properly flush the heated energon now racing through his fuel lines. His optics flickered with minor instability as calibration errors cropped up across multiple systems.

Though lacking his usual gruffness. Ratchet leaned in closer, trying to pinpoint the source, but only succeeded in inhaling more of the intoxicating aroma. A rumble rose in his chassis against his better judgement. “ your scent...", he struggled to find words between fragmented logic protocols. "It's affecting my sensor net. Overloading my functions. I need to...run a full examination. Determine why this perfume is making your scent overwhelming..." 

His field pulsed with uncharacteristic confusion and static electricity. Ratchet knew he should contact someone for assistance, but found himself unable to call out in his muddled state. The human's safety was his top concern, yet he feared touching them in this condition. Some natural, impossible chemistry was at play here, and the medic had no control over his compromised systems.

As gently as his shaking grip allowed, Ratchet grasped the human in his large palm to properly scan them from close range. His detailed medical scanners searched every inch, They gasp as Ratchet glossa meets their throat, fingers shootout to grip the side of his faceplate. 

A throttled moan escaped his vocalizer against his will. That light touch from their hands nearly shorted out his already fritzing systems. vents plume in hot exhaust. His interface panel felt too hot and tight , barely clinging to integrity protocols as the pleasure centres of his processor went haywire. 

“your scent...overloading my sensory net...cannot...resist...” Ratchet calls out through groans,his grip unconsciously tightened around the small organic in his hand. His free hand scrambled for purchase on the table, denting the metal. Something primal and powerful part of him was unravelling his mental restraints, and no calibration or forced shutdown seemed able to stop it.

Their eyes go wide. "Ratchet! Are you alright do in need to get a Perceptor or first aid?" They ask as the medic leans down into their shoulder, denta nipping at the skin as his digits try removing their shirt as quickly as he physically can. They yelp as he pulls them back together with him, his lips work along their smaller frame desperate to taste the sweet flavour and scent that had taken to their skin. capturing them against his heaving chassis. His optics blazed with static and uncontrolled charge.

"No...don't leave," Ratchet growled through clenched denta. Every fibre of his being screamed for more. His panel snapping open with an echoing click, massively engorged cables twitching in the open. Coolant and lubricant poured from his interface array, drenching the human involuntarily as he grinding against them, bright glowing pink stains their pants and paints their skin in his transfluid. 

His hands trembled, barely able to restrain their desire to claim the tiny body before him. Rational thought was impossible under the onslaught of chemical signals frying his cognition. Ratchet bucked erratically against them, whole body illuminated by dancing electricity. 

"Need you... interface protocols are in-gauged, can't fight it...please,!" he pants to the human as his spike presses against their back. Blunt node swelled monstrously at its tip.

Their back arches into each grind of Ratchet's spike. “Ratchet!” They whine out. 

Their soft noises egg ratchet on, his servos move quickly, trying to discard the pants sticking to their form, he hisses out in annoyance before finally getting them off their legs, throwing them across the medical room. Twisting them around so he can see thier eyes. 

Ratchet growls eagerly spike swiftly sliding between their thighs and against their stomach. His spike is already dripping with lubricant. As he ruts against them. Each inhale of their scent has him spiralling more. 

"Is this what you want, sweetspark? My spike filling you up?" His voice is rough with lust. Gently spreading their legs wider. Watching the bright pink stick to their legs "Primus... I bet you feel amazing." 

He moves slowly pressing his spike against them, tormenting as he presses into them inch by inch. Needy moans leave their lips, hands clinging to him desperately as they roll their hips. “Ratchet!” They cry out. 

 Their stomach bulges from Ratchet's spike, the bright pink splatter across their skin nearly has ratchet overloading from the mere sensation, not to mention the intoxicating scent of their skin. Ratchet groans deeply at the sight of his spike bulging their abdomen, his engines rumbling with feral satisfaction. One hand strokes almost reverently over the taut swell.

"So stunning like this... stretched wide around me, primus so small and tight”

Slowly he draws his hips back, then thrusts forward, grinding deeply into them. setting a steady pace, rockin into the slick heat enveloping his spike. Ducking his head, he captures their shoulder between his denta, glossa flicking against the sensitive skin as he tries to lap the perfume from their skin.

Ratchet growls deeply, thrusting harder at the way they clench around his spike. The table creaks and trembles under the force of his movements but he can't bring himself to slow down. 

"Yes, just like that," he rasps. "Keep that sweet valve squeezing me. Feels so good..."

captures their cries in a heated kiss. "Want you to overload for me," Ratchet purrs. "Let me feel you come undone around my spike, sweetspark..."

His engines are roaring furiously now, spike swelling and throbbing powerfully inside their smaller body. Ratchet groans deeply as they clench around him again, the feeling of that slick heat clenching and rippling around his spike is incredible. 

"That's it love, overload for me... you feel exquisite. So good" 

The sensations quickly become too much for his own systems to bear,the feeling, scent and the pure primal heat running through his system hits hard. With a staticky shout of Julian's name, he buries himself to the hilt and overloads powerfully. His transfluid gushes hot and thick, pumping deep into their smaller form. 

His engines vent heavily as he leans over them, face pressed into their shoulder, a deep guttural moan leaves him, Shuddering with aftershocks. When he finally leans stack to take in their exhaust and truly used form their lungs desperately inhale and exhale drawing in air as if it was their life line. 

Bright pink transfluid pudding around them as Ratchet's systems finally subsided. His optics flicker on them. “ Are you alright?” he asked softly, his human companion replied with a soft whine and nod. “ Remind me not to wear my perfume out in public” the call out in shuttered words. It makes ratchet chuckle as he leans back down to them. “a wise decision”
