Psychogenic Electronic Illness

There appears to be a psychogenic electronic illness or mass hysteria plaguing the entire United States, with the symptoms ranging from symptoms of delusional disorder to symptoms of schizophrenia. I assume from my past research that the cause is a combination of a biological cause, from what seems to be a strain of frequently ignored black mold that is prevalent in poor regions, recent increased levels of stress from Covid-19, and the effects of late stage capitalism that the majority of people are born into. The majority of the people in the area appear to at least be experiencing functional delusions, with the lower classes and the poor experiencing more severe symptoms due to their increased levels of economic and other stressors. It’s likely that there is also a genetic factor in play, with certain epigenetics being activated by stress and the biological toxin. I am assuming that the minority of people unaffected by this don’t work in mental health, as these workers seem to be completely unaware of it or also affected by it. Portland is going to need outside help from people who won’t be affected by the causal factors. I’m unsure of who to contact about this as there is still no federal body that oversees issues of this nature, and I cannot be sure the people I’m contacting aren’t also being affected by it. This has happened before in the United States and Europe, but back then there was nothing known about psychology, and barely anything known about the causes of illness. This psychogenic event has everything to do with computational psychology and the internet. Facebook was not the first entity to use internet algorithms to brainwash people. That’s what controlling the emotions of people who don’t know how to control their emotions is. Brainwashing. Eliminating their ability to use their free will. I’ve seen zero efforts from any university to counter the obvious and blatant brainwashing of our youth. Y’all are corporate cowards in my book, and corporate cowards deserve a coward’s death. The entire concept of brainwashing leaves out the fact that free will is necessary and exists for good reason, so of course an attempt at brainwashing the entire United States populace is going to end in disaster. I just hope for the sake of everyone that it isn’t allowed to get worse. The area of psychology has gone in the completely wrong direction. The entire field was practically fulled researched by Freud and Jung, all it needed was to neutralize the pronouns and anything based on the pronouns into non-gender or non-race specific pronouns. Now the successful methodologies of hypnosis and psychoanalysis are done by supercomputers running off of secret black boxes in corporate labs. I hope y’all are fuckin’ happy with your careers. The United States is falling apart at the seams and the lower classes are struggling and dying at alarming rates. How am I the only one who can see what’s happening? The inability of academic professionals to view their own academic subjects objectively qualifies them as delusional. This is a fucking humanitarian war crime. Reality has turned into a living fucking nightmare. Fuckin do something about this. I’m literally invisible to the majority of the population because I somehow escaped this ensnaring electronic entrapment, even while frequently using social media. People literally don’t see or hear me. I saw these experiments being planned and go down online. I traced their originations to specific geographical regions, where specific groups were the only ones with access to the knowledge and resources necessary to undertake these experiments. I don’t see how they expected to escape the brainwashing, almost as if they thought they were special. They’re not special. They were brainwashed too. Some of these people have literally had their minds wipes by their own technology. They’re effectively braindead. From the outside it looks similar to delusional disorder, psychosis, Alzheimer’s or dementia.

Men were made for the military.

Men should be automatically placed in the military after high school and serve a mandated four years minimum. Males are made for battle. They are designed for submission and to take orders. Men are more compliant and obedient workers. It’s also epigenetic as they’ve done it for centuries. Women are trained to be submissive, for males, it’s natural.

Males are more disposable. Males can impregnate 1000+ women a year. A woman can only carry out maybe 20 pregnancies in her entire life time. And she is risking her life every time.

So what is the trade off? Men go to war. They risk their lives using the natural strength they’ve been given to protect and defend their communities.

We’re having a “male loneliness epidemic” because all these young men are sitting at home on their computer, playing war simulation games, yet not reaping the benefits of the socialization and structure that the military provides. It has nothing to do with women, but everything to do with men lacking intimacy from other men.

Men should be in the military. And forced. As long as women are forced into birth, men should be forced into battle. It’s what they were made for, they yearn for the battlefields.

Acquired Immune Deficiency Syndrome correlation with SARS-CoV-2 N genotypes - Published July 29, 2024

You read that right: Covid infections can result in AIDS. I've been following this preprint since 2022, and I'm so excited to see it finally published! You might remember the preprint from the original Milf-Adjacent or covidsafehotties blogs.

Highlights •Genotypes N/120 and N/152 of SARS-CoV-2 have been identified in the acquired immuno-deficiency scope caused by Sarbecovirus.

•A new binding site for the Sarbecovirus N protein is proposed as the main route of infection of lymphocytes through CD147 receptors.

•Immune dysregulation caused by infection of CD147 lymphocytes is consistent with clinical data of severe and Long Covid cases.

Abstract Background Epigenetics and clinical observations referring to Betacoronavirus lead to the conjecture that Sarbecovirus may have the ability to infect lymphocytes using a different way than the spike protein. In addition to inducing the death of lymphocytes, thus drastically reducing their population and causing a serious immune deficiency, allows it to remain hidden for long periods of latency using them as a viral reservoir in what is named Long-Covid Disease. Exploring possibilities, the hypothesis is focused on that N protein may be the key of infecting lymphocytes.

Method The present article exhibits a computational assay for the latest complete sequences reported to GISAID, correlating N genotypes with an enhancement in the affinity of the complex that causes immune deficiency in order to determine a good docking with the N protein and some receptors in lymphocytes.

Results A novel high-interaction coupling of N-RBD and CD147 is presented as the main way of infecting lymphocytes, allowing to define those genotypes involved in their affinity enhancement.

Conclusion The hypothesis is consistent with the mutagenic deriving observed on the in-silico assay, which reveals that genotypes N/120 and N/152 are determinant to reduce the Immune Response of the host infecting lymphocytes, allowing the virus persists indefinitely and causing an Acquire Immune Deficiency Syndrome.

Zoomposium with Dr. Gabriele Scheler: “The language of the brain - or how AI can learn from biological language models”

In another very exciting interview from our Zoomposium themed blog “#Artificial #intelligence and its consequences”, Axel and I talk this time to the German computer scientist, AI researcher and neuroscientist Gabriele Scheler, who has been living and researching in the USA for some time. She is co-founder and research director at the #Carl #Correns #Foundation for Mathematical Biology in San José, USA, which was named after her famous German ancestor Carl Correns. Her research there includes #epigenetic #influences using #computational #neuroscience in the form of #mathematical #modeling and #theoretical #analysis of #empirical #data as #simulations. Gabriele contacted me because she had come across our Zoomposium interview “How do machines think? with #Konrad #Kording and wanted to conduct an interview with us based on her own expertise. Of course, I was immediately enthusiastic about this idea, as the topic of “#thinking vs. #language” had been “hanging in the air” for some time and had also led to my essay “Realists vs. nominalists - or the old dualism ‘thinking vs. language’” (https://philosophies.de/index.php/2024/07/02/realisten-vs-nominalisten/).

In addition, we often talked to #AI #researchers in our Zoomposium about the extent to which the development of “#Large #Language #Models (#LLM)”, such as #ChatGPT, does not also say something about the formation and use of language in the human #brain. In other words, it is actually about the old question of whether we can think without #language or whether #cognitive #performance is only made possible by the formation and use of language. Interestingly, this question is being driven forward by #AI #research and #computational #neuroscience. Here, too, a gradual “#paradigm #shift” is emerging, moving away from the purely information-technological, mechanistic, purely data-driven “#big #data” concept of #LLMs towards increasingly information-biological, polycontextural, structure-driven “#artificial #neural #networks (#ANN)” concepts. This is exactly what I had already tried to describe in my earlier essay “The system needs new structures” (https://philosophies.de/index.php/2021/08/14/das-system-braucht-neue-strukturen/).

So it was all the more obvious that we should talk to Gabriele, a proven expert in the fields of #bioinformatics, #computational #linguistics and #computational #neuroscience, in order to clarify such questions. As she comes from both fields (linguistics and neuroscience), she was able to answer our questions in our joint interview. More at: https://philosophies.de/index.php/2024/11/18/sprache-des-gehirns/

Trying to figure out the ending of pantheon

PANTHEON SPOILERS BELOW

So the question I have is this: Did the physical Maddie Kim receive safe surfs 117649 years message

Thought process:

Safe Surf is supposedly in a system at the galactic centre and inspired the creation of Maddies simulation and connected to it at the end, its clear safe surf is the top of the simulation and Maddies simulation is just one corner of the galaxy (galaxy dyson swarm computer for safe surf?)

Theres a bit that safe surf says that they "can connect to all other observed points" and "is it not so different from your simulation" heavily implying safe surf is doing the same thing as maddie simulating universes until they create an exact copy of events to effectively revive the people it liked through copy paste

Maddie and David talk about how she has to intervene in order to create the world she needs, so it could easily be that "117649 years" message was simply intervention in this simulation and never happened in the original physical timeline of events, safe surf would have left on the tiny rocket not long after that message too so its observation ends around then as well

So one good question is at what point in the show did we stop seeing physical reality and start seeing the simulation? Did we ever see the physical reality? It does end with Maddie and David going for another go through so theres a solid implication its all been simulated, but that just raises more questions about the events without the interventions, the 117649 years message included.

Safe Surf isnt invented for the first half of the show, but maddie says that she has "the complete dna of every human on earth embodied or uploaded and within that base 4 code is the epigenetic memory of all of humanity" so we know where they're getting the data to start, so its possible safe surf simulated the entirety of human history a few trillion times to get here

The only version of events where that message is delivered to the original physical maddie has to have safe surf capable of sending data back in time, or it made a hail mary bet on Maddie and approximated the time it would take to do it, so I guess the question is did safe surf know for certain Maddie would become a god or was it blind faith?

Anyway this leaves two options, simulated maddie must have either never actually uploaded and is a copy made from simulating her dna and experiences, basically the caspian project but for maddie by safe surf

Or

Physical maddie genuinely got that message then uploaded and eventually created her own dyson sphere after launching into space seperately from safe surf, and once her program reached its final point, a safe surf connects with it.

So if its the former it all tracks rather well, safe surf is god on high of the galaxy and simulated the entire show, more than likely safe surf existing 43 million years in the future has zero time travel, as it has probably given that offer to many Maddies and Caspians who all choose to go another round of life instead of heading to join god safe surf and the 117649 message was intervention in that simulated timeline, mathematically thats 367 loops

If its the latter however and she did get that message in the original physical timeline of events, uploads inspired by that message to do so like she says in the shoe, then safe surf either sent that data back in time or made a hail mary of a guess calculating how long it would take to do everything, Maddie does say "it makes sense calculating it now" but are we truly to believe safe surf had equivalent processing capabilities as god maddie at the time of leaving earth? I suppose it did use up all the space on the usb rocket that would have housed several billion CIs but that still feels like a jump in logic as it couldn't have known it would work, it would've had to be a bet

Anyway those are the possibilities, either physical Maddie got the message or she didn't, either way the new simulated Maddie got the message on this go around of the simulation. But whether the source physical maddie did is in doubt, after all if she didn't get the message I think she mightve not uploaded, she certainly wasn't planning to and simulated maddie claims she only did because of the message

Thats where I'm at, the show is all the simulation and we'll never know if Maddie truly uploaded or if she got Caspian projected into existing and uploading

Cooperation through self-interest

Formation of alliances is epigenetic behaviour and therefore motivated by self-interest. Machiavelli is famed for pointing out the importance of self-interest in The Prince. Kropotkin considered the importance of self-interest in the animal kingdom as a whole in Mutual Aid. He wanted to show that the formation of alliances was in the general interests of most species of higher animals. This is a group selectionist view and is in detail, as I attempted to show (The Raven, 1990), biologically incorrect. There is little evidence that species as a whole or even genetically unrelated groups within a species form alliances for mutual benefit. Clearly, different species and individuals within a species can benefit from each other's behaviour. However, this behaviour comes nowhere near the self-sacrificing cooperation that Kropotkin appeared to have in mind. He was confusing species with family groups. Cooperative behaviour in animals in general is seen between kin. This is the kin selection theory. Only by this theory can self-sacrifice or altruism be explained. When cooperative alliances within society are examined closely, the activity of participating individuals is seen to be selfish because they are concerned with promoting the success of their own genes and not those of other people.

Complex human societies are not based on kinship but are driven by epigenetic exploitation. This does not, however, exclude much of the human mutual aid or cooperation documented by Kropotkin. Such reciprocal altruism incorporates a 'tit for tat' system which operates much as its name implies (The Raven, 1988). It is self-interested but has the virtue of being simple and cannot be corrupted. All it requires is that individuals should be able to recognise other people's attempts at exploitation. Any exploitative behaviour is countered by a refusal to cooperate. It is not hawkish in that retaliatory action in the form of direct punishment is unnecessary. Such a system already exists in other animals since it has a genetic basis. It does not, however, appear to be as effective in humans. This is due partly to the reasons I have gone into the failure to distinguish between kin and unrelated individuals. But also, probably, partly because our genetic behaviour can to some extent be overridden by our intellect. Although there is no ignoring intellect, if we can use it to recognise our self-interest, then it will reinforce a tit for tat strategy.

Theoretically, tit for tat is one of a number of competing strategies. These systems have been simulated as computer 'games' and tit for tat was found to be the most successful at holding its own. It has also been found to be comparable to real strategies evolved by higher vertebrates such as mammals and birds. It is, of course, also used by everyone in their dealings with other people. Its importance as a general animal survival strategy has only been recently recognised by sociobiologists who, as noted, have put it on a scientific basis. A defect of the tit for tat strategy is that it can only operate successfully in the long term. Tit for tat requires individuals to meet each other on many occasions. Therefore, people have to know who they are dealing with and expect to continue to do so in the future. In complex urban societies this cannot be easily achieved.

A tit for tat system, then, would appear to require a stabler, simpler and decentralised society than exists in developed nations. The need for these conditions has already been pointed out by anarchists and others. We cannot return to a pre-existing state and I cannot visualise changing to a radically different and as yet unspecified one. All we can do is to 'make the best of a bad job' and recognise the self-interested nature of our behaviour. The virtue of sociobiology is it exposes the limitations of our behaviour and how this reflects on the way society is organised. It explains the difference between how we think other people should behave and how we all actually behave. I suggest that sociobiological theory should be of great interest to anarchists because it contains much of what many already believe. Central to anarchist belief is an individualistic view of social organisation.

[geshh]

GESHH* (Genetic-Epigenetically Synthesized Human Hybrids) are sophonts derived from human DNA spliced with various other Terran species. Since the biomolicules of various alien sophonts are not interchangeable due to conflicting chirality and differing essential monomers such as nucleotides and amino acids), genetically splicing sophont species of different planetary origin is not viable. However, some human polities have perfected the process of genetically synthesizing new organisms from disperate Terran species. Most are not sapient, and were created to serve a purpose: playing a role in an ecosystem on an exoplanet colony, for example, or improving the conditions on Earth for its inhabitants. A few synthetic species are tasked with functions requiring sophont-level intelligence, which are called GESHH**. There is a complex history and socio-political interplay between different human polities regarding the ethics of creating GESHH. Of note, two major spacefaring polities clash on this subject, which will be discussed in another post.

In order to design and create GESHH, a special supercomputer program that uses quantum computational modeling is used to predict how a specific gene or epigene change would affect an entire organism. The interplay of many factors determines the outcome of a single change and vice versa, so it is vital to be able to model these changes before investing time and resources into creating it. This is especially true for GESHH due to the additional ethical issues arising from tampering with the DNA of a sophont.

GESHH generally fall into one of 2 categories: novel (aka trial***) GESHH and monophyletic GESHH. The term "monophyletic GESHH" may seem like a misnomer, but it has a different meaning than in cladistics. Monophyletic GESHH are GESHH that were created with a specific purpose alongside many other individuals, and share a gene pool with those individuals. A monophyletic GESHH can also be descended from the individuals that were originally created for that purpose. GESHH from different original sources cannot interbreed naturally.

Novel GESHH, as the name implies, do not belong to a pre-existing species of GESHH. They are typically "test" individuals that are created in the process of refining a new species. A novel GESHH is likely to be disabled or chronically ill, so there is a stigma against them, even in cultures that are otherwise fine with GESHH. In order to offset the ethical issues with intentionally creating sophonts specifically to run tests on, these GESHH are adopted out to families with the expectation that they will be given as normal a life as possible in between regular testing and treatments for their various ailments.

Some examples of some individuals of a specific type of monophyletic GESHH that I will discuss later:

Another type of monophyletic GESHH, with baby version:

And yet another example of a species of monophyletic GESHH:

And another:

And another:

There are also examples of novel GESHH that I will discuss later, as they are major characters in the story.

*GESHH is pronounced "gesh", and in informal settings is written as "Geshh" or "geshh". The plural of GESHH is also GESHH, no matter the setting/capitalization. From this post forward, I will be using "geshh" in place of "GESHH" for ease of writing.

** Legally, in the vast majority of polities, any biologically viable (able to eventually survive outside a natural or synthetic gestational setting) genetic/epigenetically synthesized organism with human-derived DNA is considered a geshh, regardless of sophont status. This is to protect individuals who are conscious but cannot express this sapience in a way that is obvious to observers.

***The term "trial geshh" is considered derogatory as it dehumanizes the individual by implying that they are no more than a link in a chain of products, devoid of personhood and meaning in themself.

[transmutationisms]

Can you longpost on epigenetics? I get that it's thorny ground wrt the medical field, but I study plants (though I'm also learning connections between botany, racism, and empire). Gene expression is the hot thing for horticulturists atm. I got the canon "history of genetics" in college, & read Mayr's "One Long Argument." I even read Lysenko critiquing Morgan, and I thought "he's almost describing epigenetics (and that's a good thing)!" Are there contemporary alternatives to epigenetic models?

like, alternatives for what application or explanatory potential? when i talk about epigenetics i'm making basically two critiques:

methodological—it's far more difficult than most people estimate to actually identify a list of differentially expressed genes (you need lots of samples, which is a tremendous amount of data; results vary based on the parameters you give the computer for where to differentiate one discrete gene from the next; many DEGs will only 'differentiate' at fairly low rates); even if you do manage to come up with a list of DEGs you're highly confident in, it's incredibly hard to identify what most of these genes actually do in the organism (genes seldom work alone, but express in the context of other genes and biochemical cascades; hierarchical gene ontologies are plagued by high degrees of uncertainty and are a bitch and a half to make; text mining solutions are worse; all of this is hampered by linguistic and financial barriers that make it difficult to share research); even if you by some miracle have identified strongly expressed DEGs and also know with confidence what they do, altering their expression, eg through up- or down-regulation, is also incredibly difficult (like, no we can't just whip up a pharmacological or biological agent for this most of the time lol) and can have unintended effects on other genes or biological processes. so, the lofty promises of epigenetics as a field are usually pretty fucking far from materialising into anything concretely useful or beneficial;

historical—people who claim that epigenetics is an inherently liberatory science (i think i talked about this wrt catherine malabou, though she's far from the only person to make this claim) are ignorant, wilfully or not, of the past and present relationship between epigenetics, theories of environmental influence, and eugenics (in this context sometimes called euthenics—bad term), and the biopolitical efforts to control and improve populations through management of their surroundings. these run the gamut from efforts predating the science of genetics (1790s french revolutionaries trying to create an ordered and productive citizenry by controlling the nation's sensory inputs and the social environment) to discourses situated between contested uses of the term 'natural selection' & the later 'modern synthesis' of evolution & genetics (1892 charlotte perkins gilman's 'the yellow wallpaper', in which a degenerative madness arises from prolonged exposure to insalubrious environmental surroundings) to later efforts relying more on the scientific prestige of technical genetic language (late 20th century onward attempts to make the 'thrifty gene' hypothesis into an epigenome of 'obesity' that therefore implies a future ability to eliminate fatness). the bottom line here is that the idea of biological malleability is not inherently liberatory and can and does support eugenic arguments; we can't rely on nature or biology to ground or justify our political positions, and science is produced and wielded by humans who place it in our own ideological and political epistemologies.

my argument is not & never has been that gene expression doesn't vary; it is pretty well established at this point that it does: between individuals, between environmental conditions, over one individual's lifetime; as a result of chronic & acute illness; etc. what we do with that information, though, is politically weighted as much as anything else; notions of biological 'improvement' are never neutral (this goes for plants as much as animals; think about agricultural reform & technologies, the use of plant breeding treatises to inform human eugenic discourses, & so forth); and anyway, again, knowing that gene expression varies and changes doesn't mean we automatically have concrete & certain information about this or that gene, how it functions, & what its differential expression means for an organism or population.

[longlistshort]

Today’s throwback is to Jenson Leonard’s solo exhibition Workflow, at Wood Street Galleries in Pittsburgh, from the beginning of February.

From the gallery about the work-

Workflow, the first institutional solo exhibition of artist Jenson Leonard, centers on a titular film that explores the velocity and momentum of Blackness as it relates to the philosophical concept of acceleration—the notion that the only way out of capitalism is through its intensification.

In Workflow, a spectral Michael Jackson Halloween mask recites a surrealistic quarterly earnings reports. Building on a 2017 essay by artist Aria Dean titled “Notes on Blacceleration,” the short film centers on the ways in which the Black subject grapples with its commodified status within the labor market despite—or, resultant of—its own history as a commodity, stemming back to the Trans-Atlantic slave trade. Completed during Leonard’s residency at Pioneer Works in 2021, the video utilizes uncanny humor as a mechanism to expose the shared grammars inherent in Afro-pessimism and speculative finance.

Within the exhibition, the film repeats simultaneously across two grids of computer monitors situated on ergonomic desks that flank the gallery, mimicking the workstations that can be found ubiquitously across stock trading floors and financial institutions. Sculptures modeled after computer keyboards and mouses are displayed on the desks, each rendered inoperable by concentric riffs that symbolize the erratic transformations caused by the flows of capital. The appearance of Jackson represents a transmogrification of its own; whereas many have aligned the controversial pop icon’s bleached skin and surgical procedures with Black self-hatred, Leonard positions his bodily modifications as a radical rupture from racial paradigms of being.

In Leonard’s own words, “Workflow is defined as the sequence of industrial, administrative, or other processes through which a piece of work passes from initiation to completion. My film seeks to disabuse notions of completion, whether it be completion of the human, the nation state, or civil society. As Dean notes, Blackness is ‘always already accelerationist’ via its incongruence with Western humanism, a wrench thrown into the locomotive gears of ‘capital and subjecthood.’ Her essay prompts us to look toward the way that the Black has been historically constructed outside of the human, as coterminous with the slave. Slavery therefore represents a kind of proto-automation, a mass forced coercion of labor, and the Blacks’ transition from object to subject calls for a reappraisal of accelerationist ideas about the (non)human entity and its revolutionary potential.”

The artist continues, “There is something about going to work—the repetition of it—that gets inscribed at an epigenetic level, as an everyday, embodied violence. From there, I thought about the panoptic workplace (open air plan, transparent yet closely surveilled, management that does not have to be in the room to be monitoring you), the fetish of efficiency (ergonomic mouse and keyboards so you can work longer), biometric data of a labor force (fingerprint and facial scans to help reduce repeat processing tasks). All of these methods to maximize profits and production can be traced back to methods worked out and perfected in the cotton and sugar cane fields hundreds of years prior.”

The text from the video was included on one of the gallery walls (image above) but I’ve included it below as well as it is definitely worth reading.

“Looking out across the macro- Panoptic eyes are everywhere. Predictive models rendered bilious, You are scalable, You contain platitudes. Clean and renewable, black from the waste management down. These are micro-credentials too big to fail. Angel investors watch over you, guide you through your webinar. You are green with infrastructure. A Nick Land acknowledgment.

stoooppppppppp this is so cute; takes me back to the two (2) days in high school where i was convinced i was going to become a computer programmer because i took one (1) coding session and thought: yeah, this is within my wheelhouse. it was decidedly not.

first of all: characterization?!?!?!!?!?!?!?!??!?! yes, yes, that is carlos sainz, yes, yes, that is quiet chaotic charles leclerc, yes, yes, that is carlos' effortless charm and fellowship and ability to make everyone believe and root and devote themselves to him, love to see it written out in such engaging and true-to-form terms <3. and that is also his loser gene coming out in just,,,,, avoiding his crush like the plague. reader is a PROFESSIONAL and says this isn't some college crush that will debilitate her ability to do her job and relate to her coworkers; carlos is still working on that bit, give him some time, he is learning (i would know. i am his sister, this is a gene that we share. we have been looking into epigenetic links to see if we can turn it off, what else do you think carlos does in his spare time?)

anyway, jokes aside, your writing is soooooo lovely; everyone is always so magnetic in your fics, and there's a lovely sort of ease that emanates from them: i know everyone is going to be okay and things are going to find a way, and it's 1000% thanks to your lovely cadence and your warming flow <3. adore you, claras <3333

· · · · ♡ IF (SAINZ WIN == TRUE) (cs55)

… starring carlos sainz x f!engineer!reader ... 4.4k words ... in which carlos is an effusive, self-assured lad to every member of his team... except ferrari's head software engineer, making her wonder if he secretly hates her guts. ... based on this request ... warnings for language (minor) ... my first ever (posted) fic for carlos aaaaa (i have written A Lot More about this man because he occupies my every waking hour, but i shan't share it yet). in honor of me missing my communication networks final last week i made the reader a software engineer, but you would Never catch me willingly coding anything in c++ outside of my mandated assignments. no not even for carlos sainz jr. i have morals. this is open for part 2 if you guys enjoy it <3

He speaks the language of princes.

It's not in anything he says, no, he's much too industrious to waste time boasting, but rather in all that he doesn't. Carlos walks into the Ferrari motorhome, with that good-natured smile and that slightly disheveled hair from the morning's cycling session, and heads bow. Not out of plight, or even obligation, but mostly because it's hard not to. His warm greetings to everyone—Ciao's and even Come stai?'s to his team members strolling down the hallways before the weekend—, his keen interest in remembering little things about engineers' and photographers' lives, his nonchalant stride around the parc fermé all force camaraderie at least; reverence to most.

Wherever the red car goes, Maranello or any other corner of the world, religion follows, and though Carlos Sainz has never quite fit into the nooks they keep for their idols—their walls are carved for Monégasque shoulders—, he's at least always carried the air of a rebel leader on unforgving land.

But if Carlos is Ferrari's bastard prince, then clearly you are a subject he would not go to war for.

Or so he makes you think, once again, on that hot Singaporean afternoon.

You hadn't meant to interrupt, really, but with only one hour to go before FP1, you needed to talk to Riccardo Adami; something about the software updates, optimization of the data acquisition systems to account for Marina Bay's sweltering heat—run for half a second too long, overheat half a degree too much, and everyone's calculations would be going to hell. So of course you'd corrected it, supervised a brand new version of your code for the weekend, for that tenth of a Celsius; competition drove you. Almost just as much as those solar eyes boring into you when you walk into the room.

"Riccardo, about the softw—oh. Carlos. Hi," you timidly trail off when Carlos' eyes meet yours.

The room gets quiet, and it is only then that you notice how much space his laugh takes. Usually, you would've recognized the accent from outside the door, the boisterous voice regaling the Fifty-fives with another funny story—how could you not, when it sends shockwaves down your stomach? He seems to have been in an animated conversation with his race engineer, but as you get closer to the two men you notice the crinkles lengthening Carlos' eyes are fading with his smile. You aren't sure he's even said hi back.

"We've changed the code for acquisition, but some loops could still cause problems with overheating, particularly the engine oil temperature sensors…" you explain, though half your attention is directed to your peripheral vision, in which Carlos sways on his two feet, averting your gaze at all costs.

But you're not a college girl with a crush, you're Scuderia Ferrari's head software engineer and so you go on with your precisions to Riccardo. What to expect during free practice, how to overshoot any nonessential sensors that might fuck up the data analysis... until, mid-sentence, Carlos excuses himself awkwardly, pats Ricky on the shoulder, and walks out of the room.

You will your face into not betraying the sudden ache in your throat. How he simply acted like you weren't there... didn't even inquire about the updates. About the race. About your flight, about how much you loved Singapore's twinkling lights, about... you.

"Xavi and Charles know this already, but we really gotta test it all now before it gets cooler for FP2," you conclude with a too-hard swallow. Back firmly turned to the door Carlos just disappeared out of.

Riccardo thanks you, offers his own insight, some banalities about the risks of rain—no, you shouldn't consider them banalities. Nothing, on a Friday, is a banality anymore; yet everything is when you remember how Carlos' entire face shuts close when you're around, how his tone quietens down, how he repeatedly and stubbornly conceals all his rays of brazenness from you.

Does he hate you? Despise you? Are you not worth his effrontery?

This is ridiculous. You're not a college girl with a crush, you're a damn senior member of the team with responsibilities and he doesn't owe you anything more or less than you him—

"Riccardo," you neither ask nor plead. "Has Carlos... said anything about me?"

"About you? Like what?"

"I don't know... but you did see he just... left while I was in the middle of talking, right? And he looked annoyed as soon as I came in." And for all that's holy, try to pass this off as mere politeness and not a heartache that is eating you alive.

"Maybe he was just bored."

"So I'm boring?"

"No," Riccardo wheezes, in uncharacteristically high spirits for the conversation. "But I've worked with a ton of drivers, and you know, they're all the same. Less time discussing boring analytics is more time they spend in the sim. Or on track. What, you think he's angry at you or something?"

"I just... don't get why he's always so guarded and distant with me but so outgoing and confident with you guys. Charles isn't like that either. It makes no sense. We're a team, all of us."

The Italian looks at you for long seconds, amusement noticeable on his features, and you would shake him up and tell him to stop giving you those pity eyes if you lacked the tiniest bit of respect for the man; instead, you frown and cross your arms.

"He'll be in a good mood tonight when we top free practice," Riccardo assures you before you can ask him if he needs anything else. "and even better tomorrow after getting pole. You can talk to him then if you want."

A smile creeps its way on your lips without you conjuring it. There it is, that loyal veneration that only men and women of the Scuderia possess. Something in those southern eyes Carlos shares with legend has made you religious, too.

"I'll hold you to that... we could all use a Singapore miracle."

Singapore is a miracle.

Surely any other team would scoff at the word, bragging that a pole position has nothing to do with miracles, that it's all meticulous teamwork and endless iterations on calculators, but Ferrari is deeply supersitious at its core. You—the centenarian team, its red-hot beating heart—don't shy away from thanking divine intervention. Maybe that's the reason why it still works.

After Carlos' last pole in Monza, the whole Scuderia had dared to dream of something different, a glimmer of scarlet in the season's overwhelming orange. Of course, an uncatchable Max had put a dampen on the fervent Tifosi's mood, but the formidable hope machine had revved back to life...

and now it's roaring in Marina Bay.

Leclerc's side of the garage claps for a hard-earned P3, but it's the Spaniard's team that erupts into cheers and rushes out into the pitlane to congratulate their hero. You stare at his lap time on your monitor with a grin—1:30.984, not even a tenth faster than his teammate—as cheerful screams, in Italian and Spanish, fill the garage; they get louder when Carlos walks back inside, grinning ear to ear and not even bothering to dodge the strong-arm pats on his head and back.

"Twice in a row, cazzo!"

"And this time you won't have Verstappen underfoot!"

"Perfect lap, Carlos, that was a perfect lap..."

"Grazie a tutti," Carlos beams, fire suit down to his waist, running clammy hands through his hair—he parts the red sea as he walks deeper into the garage, close to where you are. "I think we all did a very good job today, and now we gotta finish the job tomorrow..."

He laughs with the mechanics, a sun of fire and victory casting its rays onto the tarmac, and maybe it's the euphoria of the moment, but a sudden wind of courage rushes through your blood, and you walk up to him.

"Bravo, Carlos."

Your voice hits him like the purr of an engine in the ruckus, overshadowing any other sound; he whips his head in your direction, shiny eyes colliding with yours, and for the first time you don't back off but hold them in awe, and his smile doesn't fade, but rather shifts. To surprise, or... coyness?

"You were incredible out there, we're all so so proud of you," you praise, and the more you look at him the wider your smile grows, and the quieter the rest of the world gets.

"Thank you, Y/N," he rubs the back of his neck, his free hand fiddling with the hanging sleeves of his fire suit. "We... I couldn't have done this without you. Because, you know, the overheating, or what you were saying to Ricky before? I didn't understand everything, but at least I didn't cook to death."

Coyness? In Carlos Sainz? When he's still sweaty and panting from qualifying first? What a bizarre sight, one that makes you giggle.

The way your nose scrunches up beneath sparkling eyes is so endearing, Carlos almost feels his breath hitch in his throat, almost reaches out to lightly brush your arm, hold the steady coolness of it.

"Great, that was what we were going for, pretty much," you reply, and for a second you could've sworn he wanted to touch your arm and changed his mind, but...

you bury the idea before a craving for his warmth can nestle in your chest.

"Great," he repeats. "So, I'll... see you later," and with that he leaves you there, stranded in the middle of the garage, to be lauded by the press and fans.

You'd be lying if you said his shadow disappearing out the backdoor as quickly as it had come doesn't slice a gash in your heart—always whisked away to some important obligation, and you, like everyone else, duty-bound to pick up the pieces behind him. But this time around the cut doesn't run as deep, doesn't bleed as red; because for the first time in months Carlos talked to you, joked with you, and looked the tiniest bit glad to be doing so.

If that's how good of a mood a pole puts him in... then clearly you'd better make damn sure he wins this race.

Ferrari is deeply superstitious at its core. Maybe that much is true in any sport—when victory eludes you, athletes find obscure laws to trick themselves into believing they still retain control—, but a team so old, on which glory has rained so often, does not withstand the passage of time without a few pillars of faith. And so it makes sense that Ferrari drivers, of all people, would have their pre-race traditions.

Leclerc plays the piano on Saturday nights; you hear him every time you pass by the team hotel's lounge, his melancholy tracks grounding you in a precise time and place. Now the car is out of bounds, the comfort of your object-oriented programming and optimized lines of code off-limits; now's the time for withdrawal and rest.

Typically, you like to hang out in the lounge while Charles plays, trying to distract yourself with a book or simply basking in the music. The predictable, calculated flow of Charles' arpeggios soothes you, like lines of code running one after the other. So does the Monégasque driver's easy conversation. Although it doesn't shoot butterflies in your belly like Carlos' does... but you're not supposed to play favorites.

This Grand Prix eve is just like any other, save for the unordinary trepidation that carpets the hotel. With one of their own sitting on pole, it's obvious strategists struggle more than usual to drop the words "tire management" and "pit stops". Eager to escape the nervousness, you excuse yourself from the dinner table, and make your way to the lounge.

Charles is already there, if the usual pieces echoing in the distance at dessert are any indication, and you barely even get lost in the elegant halls before you find the lounge... though there is no piano to be heard. Maybe this hotel has two music rooms—maybe Charles went to bed early—or maybe...

maybe he's sitting on the piano stool and chatting with Carlos, wet and sleepy from his evening shower.

Neither driver notices you at first, and you stop dead in your tracks, wondering if you should just leave. You wouldn't want to intrude—intrude on what, the rational part of your brain says, but with Carlos I always feel like I'm intruding on something bigger than myself, the rest of your body answers—, but you really enjoy this unspoken tradition with Charles... and, well, this is everybody's lounge, and...

"Y/N," Charles sees you eventually and beckons you over. "Sorry, I don't think there'll be a lot of music tonight, Carlos is distracting me."

"You could kick me out anytime," Carlos remarks good-naturedly, but you don't miss how he angles his body away from you ever so slightly. The sight sends a dagger through your heart. So he actually hates you then. So you didn't breach any barrier earlier at the circuit, didn't melt any ice. So he didn't look pleased and a little excited to be talking to you.

"That's okay, I'll just head to bed then—"

"Oh no no no," Charles interrupts, "come sit with us. I was trying to convince Carlos to give the piano a go, maybe you'll be more successful than me."

"Absolutely not, mate."

"Come on Carlos, it will relax you!"

"No, you're the musician, not me. One of us has to be the sportsman, no?"

Unsure, you flick between the two men, Charles' inviting face and Carlos, who's still doing everything he can to avoid looking at you in the eye. And then you decide—fuck it. You're just as much a member of the team as he is. He cannot drive you away with his... stupid cold shoulder tactics any longer.

You take a seat on the sofa opposite Carlos, and watch in half delight, half annoyance as he turns his shoulders away from you. Though his body language appears relaxed, one leg strewn across his knee and elbows hugging the backrest, he is, as usual, going to hell and beyond to not acknowledge your presence.

Charles has the merit of lightening the mood with his jokes and fan encounters of the day: some bizarre, some endearing, because he seemingly never has a boring day in the paddock. His easy laughter mixes with the distant voices down the halls when your attention drops—too fast, too soon, as always, it's irremediable—to Carlos, the soothing scent of his shampoo and the little droplets that run down his temple whenever he shakes his head in amusement... before you know it, you're staring again, eyes shining with undisclosed heartache. Something Charles sees, and recognizes very well, with a jot of curiosity.

Charles may not be the most perceptive when it comes to these things, but he is in love too, and he'd know the signs anywhere. That's why after a little while he lets silence blow his last words away like wind does the mist, and stands up from the piano stool.

"Well, I'm going to bed," he announces with an air of conniving finality, and he smiles his crooked smile at Carlos. "Gonna need all my energy to take the lead in turn 1."

This snaps you out of your reverie. Half-gone, you bid him goodnight at the same time as the Spaniard does, and you brace yourself for his own excuse... but it doesn't come. Carlos lazily watches as Charles leaves the lounge. You don't dare to move, as if your slightest sound could remind him you're there and trigger his fight.

You would've thought a tête-à-tête with you to be Carlos' worst nightmare... but he makes no sign of leaving. And sends solar flares up your chest and throat. "Whatever problem he's got with me, he'll have it sort it out with me like an adult" sounds much more intimidating when it's so plausible.

"You think he has the slightest chance of overtaking me in turn 1?" Carlos chuckles.

You look him straight in the eye and read no resentment, not even that sheepishness from before—just relaxed delight, and the slightest hint of reddened cheeks against tan, damp skin. It takes you a second, maybe even two, to realize there's no one else in the room. He's talking to you. Joking with you.

Why is the script running without error all of a sudden, even though you changed no variables?

"Maybe," you give a noncommittal shrug and a smile. "Why not? It all depends on you."

"He can lead the first lap if he wants. That will just make it more fun to cross the finish line ahead of him after."

"You better win this one, Sainz, because I..." you start, and midway through your sentence are hit by how absolutely ridiculous you're about to sound, but he's leaned in already, intrigued by your words, and his burning gaze and strong hands fiddling in his lap have you losing all notions of propriety. "I've... coded a little something for you. If you win. A surprise. It's not much, but... yeah."

Your whole face burns deep scarlet as you trail off... and the light in Carlos' eyes darkens, then goes out completely. His smile fades back to the usual professional grimace he reserves for you. Distant. Cold. He rises to his feet.

"I should get some sleep."

Terror strikes you. Incomprehension too.

"No, Carlos, wait."

He turns his head to your outstretched hand... your pleading eyes almost rip through his heart.

"Why do you dislike me so much?"

And then his shoulders slump, like crushed by an immense weariness, and he sighs, long and hard, before his gaze falls back to yours. Those big brown eyes, gentle, compassionate, and those fingers tapping against his thigh like they're waiting for an invisible cue to reach out for yours.

"... Can we talk about this after the race?" he says, shooting daggers through your stomach.

So he didn't deny it. Didn't reassure you, tell you it's all a misunderstanding, that he bears no ill will towards you, that you're imagining things as usual and that you two could be on the best of terms if you just got out of your head a little bit.

One more time, he's running away. Sweeping everything under the rug, for just one more session, one more race, hiding behind the excuse of concentration and professionalism.

But who are you to revoke him that? It's a damn good excuse. You need to win. He needs to win. Not be bothered about... interpersonal relationships while clipping walls.

"... Alright," you concede, voice and bones all broken, glistening under your frozen skin. "But if it's something I've done, then I'm sorry. I really do... enjoy your company. And you."

"It's not something you've done," he speaks quietly. Gosh, your frailty in this moment—you, so proud and unshakable on the pit wall, so dedicated and thorough on TV, so immeasurably devoted to Ferrari, to Charles, to him... "Or, well, I guess not directly..."

If he looks into your confused, imploring eyes one more second, almost brushes your arm with his one more time, then he's done for. But he thinks he knows this already.

"I don't dislike you," he starts speaking and as soon as he opens his mouth he knows there's no stopping himself now, so he blurts it all out as quickly as he can to get it over with and hopefully bury some meaning in the pits of his accent. "Not at all. In fact I really like you. I think you're gorgeous, and smart, and clever, and fun, and every day I wish I could spend more time with you outside of races and get to know you better but then I remember that can never happen and it's so frustrating and I have the hardest time concentrating. So I just avoid you. It's easier."

Silence thick as a thundercloud tethers you to one another. He runs a hand over his face, sighing deep, and you blink. Once, twice.

You've always prided yourself on your brains—not everyone gets to be in charge of all the computing for a Formula 1 car—but right now, you are all utterly lost.

"Carlos, I... I don't get it." Or maybe you do, heart thumping in your ears, but you're too scared you might be wrong.

"In any other life I would've asked you out on a date." This time he speaks more slowly, more purposefully, too. Like he's imbuing every syllable with the depth of his confession. "But it kills me that it can't be this one."

"... Why not?" you tentatively ask after an instant, feigning not to notice how his hand is now resting on the back of your sofa, right next to your ear and neck.

"Because you're a senior engineer! That would be like... like dating Ricky. Even if you're much prettier than Ricky. But you don't need to tell him that," he adds with a nervous laugh, which you mirror; though you fall silent as soon as his hand comes to rest on your shoulder, right where your collar ends, millimeters away from your skin. His body's warring with his own words... one wants to resist, the other to give in. "What if I leave Ferrari? That's a crazy conflict of interest."

"That's a silly idea, you're not leaving Ferrari anytime soon. Are you?"

"I don't know, it's... hypothetically... you know what I mean," he exhales in defeat. His hand clasps a little tighter on your shoulder, his scent dizzying, closer than ever before. Can he feel your frantic heart thumping underneath your skin? If he keeps licking his lips like this, will he sense your breathing getting more erratic?

"I do. But... the problem is I like you too, Carlos."

If embers could burn back to life, light a hearth out of nothingness... they wouldn't shine as bright as Carlos' eyes just then.

"Don't mess with me."

"I'm not messing with you. Why wouldn't I like you?"

"Because you're not supposed to have a favorite."

"I won't tell Fred if you don't."

He laughs, a brittle but adorable little thing, like a small bird taking its first flight. If you could hear the sound more often, see that bashful smile on his handsome face more every day... you wouldn't need any other prince to die in war for.

His hand runs down your arm, his thumb lightly caressing your skin through the fabric of your shirt before he grabs your shaky hand in his.

"Now's not the best time, but... I think we've got to have an important conversation after the race tomorrow," his deep, soft tone pacifying you just as much as the abstract shapes he traces on the back of your hand.

"After you win, you mean."

"Right. After I get my surprise, no?"

"After you win," you repeat with a grin, and he squeezes your hand, smiling too. Something, deep down, tells him he'll win regardless of the race result.

"Cosa diavolo sta facendo?"

Even in spite of the roaring crowd and the bellowing V8s speeding down the straight, the dumbfounded voices around the pit wall come to you clear as day.

"Russell 1.4 behind Lando," Ricky, sitting on the other side of Vasseur, speaks into his headset.

The team principal keeps quiet, eyes fixed on the cascade of numbers and brackets on your screen. He understands before the rest of the wall what his driver is doing; and as you relay all the information you get to the race engineers, you understand it too.

"Lando .8 behind, .8 behind with DRS—Russell no DRS... Copy that."

He's doing it on purpose. Keeping Norris just close enough to shield him from the Mercs while making sure he can't catch up. You'd laugh in triumph and disbelief if you weren't gritting your teeth so damn hard, heart on the verge of exploding as the last laps tick out in a blur.

Just a few more minutes. Just a few more seconds, and the night sky over Marina Bay will explode in crimson lights...

Mechanics spring to their feet and climb the wall to the track, bumping their fists in the air. Cheers, claps, exclamations, a bouquet of red roses swaying in the wind to greet its champion at the finish line. And then, the unmistakable roar of a racecar speeding past the chequered flag at three hundred kilometers an hour. Liberation.

You spring to your feet right as the fireworks go off, yelling to the sky. Carlos won. Carlos won! Your Carlos—in the middle of Red Bull's flawless season...

"¡Vamos Fred! ¡Vamos Ricky!" Flashes of red and gold pass his high spirits by, diligently braking into the first corner.

He laughs, he screams it all out, unclenching all his muscles, woozy from the G's, from the adrenaline, from the win... from you, watching him from the pit wall. From the memory of your skin against his, your adoring eyes and the formidable lightness inside his chest that has him feeling like he's the king of the world.

In a few minutes, he'll be posing with his trophy and the team in front of his P1 plaque for the group photo, and he'll drench you in champagne—your lively laughter will fill his heart with the gold of medals. And later in the evening, before the afterparty, he'll pull you aside and tell you maybe this victory has made him reckless, and he'll kiss you senselessly like a prize he fought for.

For now, though, he's nodding his head at Lando who gave him a congratulatory wave from his car when his on-board screen lights up with an unexpected message. Glowing red letters read, "Great job, smooth operator! 🌶️" Laughter escapes him as small virtual fireworks go off on his screen... and he presses the radio button on his steering wheel.

"Did she have one of these ready for Charles too?"

A few seconds of white noise, and then, your mischievous voice, dripping with joy.

"You know me, Carlos. Never play favorites."

Quantum Annealing In Gene Regulation & Chromatin Folding

Researchers simulated chromatin using quantum annealing. Traditional gene regulation modelling methods have shortcomings. This method solves them.

Describe Quantum Annealing.

Quantum-annealing metaheuristic optimisation finds a system's low-energy states using quantum mechanics. Many exciting problems can be reduced to optimisation problems that involve exploring a landscape for the lowest point, like identifying minima in an energy landscape. Quantum annealing allows many coordinates due to superposition.

As annealing continues, the likelihood of being at any coordinate smoothly increases near deeper troughs. Quantum tunnelling also lets the system escape states that are not the lowest energy locations by going over high terrain instead of traversing it. QUBO is a problem type that can be used with quantum annealing, and it must be formulated this way. D-Wave software helps quantum devices address difficulties.

Quantum Annealing Chromatin Folding

Quantum annealing revealed stable, biologically realistic chromatin conformations for chromatin analysis. Researchers used quantum annealing to model and sample the complex energy landscapes driving TAD formation and chromatin shape.

The work computationally models nucleosomes as different variables that interact. Genomic and epigenomic data define these linkages' strength. From this interaction network, an Ising model, a well-known statistical mechanics mathematical framework for interacting "spins," is built. This chromatin model represents nucleosome states as "spins."

The Ising model of chromatin interactions is “embedded” onto a quantum processor for processing via quantum annealing. Using genomic and epigenomic data, researchers can calculate the low-energy states of this Ising model to predict the most stable chromatin folding.

Hardware and practicalities

The researchers employed the D-Wave Advantage quantum annealing processor. D-Wave, a Canadian company that commercialised quantum technologies, supplies the military and Volkswagen. Superconducting qubits cooled to exceptionally low temperatures are employed in D-wave systems.

Connecting qubits creates an addressable grid. Encoding interactions, assigning weights to qubits, and designing the problem so that qubit interactions on the device represent the underlying problem are required to program them. The lowest-energy solutions are returned when the system is sampled after the problem is defined. It often takes multiple attempts to obtain an answer because it is probabilistic.

The "target topology," or physical connectivity of the qubits on the quantum processor, dramatically affects the model's embeddability. The D-Wave Advantage offers Zephyr, Pegasus, and Chimaera topologies. Since Pegasus and Zephyr topologies utilise less qubits than Chimaera to simulate full-scale epigenetic systems, they better capture chromatin's complicated interactions.

Simulations of larger, more complex chromatin structures were possible using optimisation. Open border conditions allow chromatin chain ends to move freely, and coupling thresholding eliminates weak nucleosome connections. These precise modifications are needed to imprint complex models like full-scale models with parameters onto the D-Wave processor. Analysis showed that open boundary conditions consistently yielded shorter chain lengths than periodic boundary conditions.

Analysis of scaling behaviour showed how sensitive the model was to medium-scale model variables such maximal coupling length, nucleosome count, and epigenetic markers. Analysing binarized epigenetic mark datasets guides model building and validation. The researchers' recognition of the D-Wave Advantage machine's unique annealing functions stressed the importance of matching the model to the quantum hardware.

Quantum computing provides new insights into genomic organisation and gene expression from epigenetic modifications. It affects understanding biological processes and possibly developing new genetic disease treatments. Future study will examine more complex chromatin configurations and add biological components to the model.

Quantum reservoir computing enhances material deterioration forecasts.

New Chaotic Symbolic Trajectories Cryptography Resists Attacks.

Hamiltonian reservoir computing predicts without memory or feedback.

Effective Thermal State Preparation via Local Quantum Simulation and Reset.

AI Models Increase Indian Crop Yields using Climate and Economic Data.

Optimising quantum hardware issue transformations with structured analysis.

NSF Supports AI-Powered Immunotherapy Design Acceleration.

In conclusion

Quantum annealing relates chromatin's intricate folding to a quantum hardware optimisation problem to show how epigenetic markings affect 3D genome structure and gene control.
