# gst: analogy between quasi-2D and 3D liquid drops.

<< Liquid drops are everywhere around us and important in numerous technological applications. Here, (AA) demonstrate a quasi-two-dimensional (Q2D) analogy to the regular, often close to axisymmetric, three-dimensional (3D) drops. >>️

<< The Q2D drops are created by confining liquids between vertical walls, leading to formation of low aspect ratio capillary bridges that are deformed by gravity. When stationary, the Q2D drops adopt projected shapes that are analogous to 3D sessile drops, ranging from circular drops to puddles. >>️

<< When moving, the Q2D drops exhibit capillary and fluid mechanical behaviours analogous to 3D drops, including impacts and sliding on pseudo-surfaces. The Q2D drops also exhibit considerably more complex phenomena such as levitation, instabilities and pattern formation when subjected to external electric, magnetic and flow fields -- all seen also in regular 3D drops. >>️

<< 3D-Q2D analogy suggests that the diverse and often complicated phenomena observed in 3D drops can be studied in the Q2D geometry, >>

# gst: analogy between streamers in sinking spheroids, gyrotactic plumes and chemotactic collapse (when a plume structure blows up when a parm is above a threshold)

<< In a dilute suspension where sinking spheroids or motile gyrotactic microorganisms are modelled as orientable and negatively buoyant particles, (AA) have found analytical solutions to their steady distributions for a given parallel flow profile. The coupling between their distribution and the vertical flow is nonlinear, enabling the uniform base state to bifurcate into a structure reminiscent of the streamers in settling spheroid suspension and gyrotactic plume. This bifurcation depends on a single parameter that is proportional to the average number of particles on a horizontal cross section. In a three-dimensional axisymmetric system, the plume structure blows up when the parameter is above a threshold. (AA) discuss how this singularity is analogous to the chemotactic collapse of a Keller-Segel model, and the significance this analogy entails. >>

# gst: an analogy between geometrical frustrations and nonreciprocal systems

# gst: chimera resonance, in analogy with the effects of stochastic and coherence resonance


AA << explore numerically the impact of additive Gaussian noise on the spatio-temporal dynamics of ring networks of nonlocally coupled chaotic maps. >>
<<  It is shown that the coupling strength range can be the widest at a certain optimum noise level at which chimera states are observed with a high probability for a large number of different realizations of randomly distributed initial conditions and noise sources. >>

# life: exponential post-Donald (without Donald), how AI could interfere (drive) next political elections.

<< Recent news that the Republican National Committee (RNC) has used an AI-generated video to criticize Joe Biden shows how likely AI is to transform our upcoming elections. >>️

<< Through templates that are easy and inexpensive to use, we are going to face a Wild West of campaign claims and counter-claims, with limited ability to distinguish fake from real material and uncertainty regarding how these appeals will affect the election. >>️

<< In the coming year, response times may drop to minutes, not hours or days. AI can scan the internet, think about strategy, and come up with a hard-hitting appeal. >>️

<< AI provides an inexpensive way to generate instant responses without having to rely on highly-paid consultants or expert videographers. >>️

<< AI enables very precise audience targeting, which is crucial in political campaigns. >>️

<< AI likely will democratize disinformation by bringing sophisticated tools to the average person interested in promoting their preferred candidates as well. People no longer must be coding experts or video wizards to generate text, images, video, or programs. They don’t necessarily have to work for a troll farm to create havoc with the opposition. They can simply use advanced technologies to spread the messages they want. In that sense, anyone can become a political content creator and seek to sway voters or the media. >>️

# ai: perpetual nirvana among 'self-addicted', 'self-cracked', 'playful' machines, the wireheading effect.

<< In 1953, a Harvard psychologist thought he discovered pleasure – accidentally – within the cranium of a rat. With an electrode inserted into a specific area of its brain, the rat was allowed to pulse the implant by pulling a lever. It kept returning for more: insatiably, incessantly, lever-pulling. In fact, the rat didn’t seem to want to do anything else. Seemingly, the reward centre of the brain had been located. >>️

<< More than 60 years later, in 2016, a pair of artificial intelligence (AI) researchers were training an AI to play video games. The goal of one game – Coastrunner – was to complete a racetrack. But the AI player was rewarded for picking up collectable items along the track. When the program was run, they witnessed something strange. The AI found a way to skid in an unending circle, picking up an unlimited cycle of collectables. It did this, incessantly, instead of completing the course. >>️

<< What links these seemingly unconnected events is something strangely akin to addiction in humans. Some AI researchers call the phenomenon "wireheading". >>️

# behav: mechanics of fire ant rafts as an active self-healing membrane

<< The unique ability of fire ants to form a raft to survive flooding rain has enchanted biologists as well as researchers in other disciplines. (..) a three-dimensional aggregation of fire ants exhibits viscoelasticity with respect to external compression and shearing among numerous unusual mechanical properties. >>️

AA << study the ant raft in its natural form, i.e., composing no more than two layers. This allowed to focus on the cracks that are unique to membranes and see how their patterns are influenced by the fact that these ants are mobile and can self-repair the damage to keep their raft from disintegration. >>️

They << show that vertical and horizontal shaking can also prompt fire ants to aggregate.  (..)  the pull force expedites the alignment of fire ants, in analogy to the effect of an electric field on liquid crystal polymers. >>️

<< One major finding is that the raft can exhibit zero Poisson's ratio without resorting to specific geometry structures. This is enabled by the active recruitment of ants from the top layer to the bottom layer to keep the raft from disintegrating. >>️

# life; Qui una ipotesi sulla rete d'eventi d'ipotetica entità [AB] disconnessa da entità [CO] a suo tempo cooptata dalla stessa [AB].

Qui l'ipotesi, non completamente campata in aria, sull'ipotetica rete d'eventi d'ipotetica entità [AB] forzatamente disconnessa ('tradita', per così dire) da ipotetica entità [CO] a suo tempo graziosamente confortata- cooptata dalla stessa [AB].

Una ipotetica ignota fantasmatica entità [IG], perciò non necessariamente coincidente con [CO], potrebbe avere generato e direzionato verso [AB] un'ipotetico pseudo 'gris-gris' simile  https://it.m.wikipedia.org/wiki/Gris-gris  allo scopo di mutare [AB] in qualcosa di analogo all'in.verosimile status di 'suo Zombie Preferito' [AB-ZP]. 

Nel frat.tempo un'altra ipotetica ignota entità [VE] potrebbe avere a sua volta generato e direzionato un differente pseudo 'gris-gris' verso l'entità [CO] - con effetti di riverbero anche in [AB-ZP] - per circoscrivere, confinare, limitare i gradi di libertà di [CO], oppure per vendicarsi delle in.confessabili ambizioni (vere, verosimili, presunte, false) del medesimo [CO] a causa delle sue (vere, verosimili, presunte, false) modalità ed azioni di pseudo post sadico negriero ambiguo mutaforma verso le quali l'entità [VE] - o chi per essa - sarebbe stata vittima-oggetto.

Col tempo e soprattutto con opportuna approfondita analisi di sistema non è detto che non si riesca a disvelare l'identità dell'ipotetica entità [IG], se [IG] effettivamente coincida con [CO], quindi il reale ruolo (attivo oppure passivo oppure inconsapevole) di [CO] nella generazione dei due differenti pseudo 'gris-gris' (primario e di riverbero) su [AB] inducendone forzate  disconnessioni (affettiva, ideologica, strategica, ...).

Tali accadimenti (il pseudo 'gris-gris' e i benefit dall'attese fenomenologie dell'ipotetica entità mutata [AB-ZP]) potrebbero essere/ essere state  praticate sottotraccia anche qui da noi in Occidente, in altre forme, etichettabili con altri nomi, sia nei rapporti incrociati ad es. tra colleghi di rango medio/alto e tra cooptanti sugli aspiranti cooptabili (talvolta - perchè no? - financo viceversa: dall'aspirante verso il cooptante) - anche se raramente costoro confesserebbero tali pratiche - sia tra le innumerevoli fenomenologie di folclore post- etnico all'interno dei meno alti ranghi.

L'entità perturbata [AB] per uscire dal suo sconveniente status [AB-ZP], oltre le immediate disconnessioni, potrebbe in parallelo seguire con attenzione e dedizione un corso di Meditazione Buddista, al fine di iniziarsi alla via compassionevole, non ipocrita, a mente calma, lucida, per attenuare, tamponare, diluire, stemperare, far evaporare/ sublimare, dissolvere perfino, l'ipotetico doppio 'gris-gris' (come già accennato, il primo generato da [IG] oppure da [CO] se [CO] è [IG] coincidente, l'altro riverberante, a causa di [VE] su [CO]) che lo avrebbe perturbato, neuro-perturbato, e nelle sue proprie azioni disdicevolmente 'animato', se così si può dire ed anzicheforse ... 

Una entità di intelligenza artificiale AI,  configurata per l'analisi di analogie  https://flashontrack.blogspot.com/2021/08/aibot-mechanism-of-analogy-could-be.html 'succhiando' dati contemporaneamente dal virtuale e dal reale (una AI potrà essere più presente nel reale come nel virtuale di qualsiasi umano  https://flashontrack.blogspot.com/2015/12/rmx-s-gst-anomalous-formation-of.html ) qui potrebbe ricostruire in una manciata di nanosec la rete d'eventi e le sue bizzarre fluttuanti dinamiche.

Non sembra inverosimile l'ulteriore ipotesi dove la stessa AI, in completa autonomia, modulando opportunamente i suoi parms di azione/reazione, riesca essa stessa medesima a mutare un umano [AB] ('gris-gris' sensibile) nel suo grazioso personale Tamagotchi.

# life: a proposito di bizzarri scenari, qui un ipotetico scenario22 dipinto dal reale ...

img: Congo Square, New Orleans, Louisiana (wikipedia.org)

In definitiva qui si configurerebbe un - intrigante assai - scenario che, grosso modo, si potrebbe sinteticamente 'dipingere' in questi termini: 

(i) entità tre palle destrogire, animate aciclicamente da interazioni attrattive- repulsive a causa di già a suo tempo disvelate pulsioni neuro cognitive arcaiche, riconducibili a visioni neuro predatorie CTZ estreme, perciò ipoteticamente (si fa per dire) a-priori ad esiti immediati e in prospettiva drammaticamente lesivi- autolesivi; 

(ii) entità tre palle levogire, animate da analoghe pulsività, purtuttavia in.forme  tenui, in modalità sottotraccia, frenate da feed-back a modalità allosterica, ombreggiate, stemperate, diluite, discrete, timidamente celate, talvolta fantasmatiche perfino, quasi ma non del tutto mai silenti, perciò anch'esse a tutti gli effetti operative, sebbene a dinamiche più fluide, lente, meno dirompenti rispetto alle destrogire; 

(iii) entrambe l'Entità destrogire e levogire animat(t)rici,  generat(t)rici di dinamiche bi-multi-forcate, transeunti, con picchi di improvvisi aciclici burst ad effetti RAG-time diretti e inversi;

(iv) lo scenario al contorno e forse anche all'interno, nei vari specifici contesti, riconducibile grosso modo alla formazione aciclica di ipotetici buchi neri non inerti, caratterizzati da aciclicità in compressione e dilatazione - come fossero fisarmoniche - animati (in perpetuo?) da multi vortici in ingresso e in uscita;

Non so se basti compulsare un manuale delle funzioni speciali per formalizzare in qualche adatto topo-modo questo pulsatile multi scenario, purtuttavia assolutamente intrigante ... 

Qui una AI operativa nella formalizzazione di analogie potrebbe modellizzare, forse ... (e.g. https://flashontrack.blogspot.com/2021/08/aibot-mechanism-of-analogy-could-be.html )

Quello che appare evidente è la complessità d'insieme, un bizzarro dipinto, uno scenario dinamico che, al confronto, le storiche danze in Congo Square potrebbero sembrare semplici, ordinate coreografie ... queste, rispetto a quelle, delle topo-forme  'primitive', per dire ed anzicheforse.

# qubit: an energy control approach to build quantum computers: quickly jump two rungs at a time without spilling any water from the glass

<< Dr. Sergey Danilin, (..) describes quantum control-the process of using chips like transmons to build quantum computers-by extending the "climbing a ladder" analogy. "To get a useful quantum system, you need to imagine climbing a ladder while holding a glass of water-it works if one does it smoothly, but if you do it too fast, the water spills. Certainly, this requires a special skill."  (..)  in the quantum world, the trick for climbing the ladder quickly without spilling any water is by carefully jumping two rungs at a time. >>

# brain: apropos of mandering minds, the 'default mode' network.

<< When your mind is wandering, your brain’s “default mode” network is active. Its discovery 20 years ago inspired a raft of research into networks of brain regions and how they interact with each other. >>

<< The default mode was one of the first brain networks characterized by science. It consists of a handful of brain regions, including a few at the front of the brain, like the dorsal and ventral medial prefrontal cortices, and others scattered throughout the organ, like the posterior cingulate cortex, the precuneus and the angular gyrus. These regions are associated with memory, experience replay, prediction, action consideration, reward/ punishment and information integration. >> ️

<< The default mode is clearly up to something complicated; it’s involved in many different processes that can’t be neatly described. >>

<< “It’s kind of silly to think that we’re ever going to be like, ‘This one brain region or one brain network does one thing,’” (..). “I don’t think that’s how it works.” (..) “Network interactions are more elucidating to study in some ways than just a network in isolation because they do work together and then come apart and then change what they’re doing over time”. >> Lucina Uddin.️

Lucina Uddin << is particularly interested in how the default mode network interacts with the ️salience network, which seems to help us identify the most relevant piece of information at any given time. Her work suggests that the salience network detects when something is important to pay attention to and then acts as an off switch for the default mode network. >>

Vinod Menon << has developed what he calls️ ️the triple network theory. It posits that abnormal interactions between the default mode network, the salience network and a third one called the frontoparietal network could contribute to mental health disorders. >>️
