# life: a proposito di bizzarri scenari, qui una transizione 'a gradino' di ipotetico scenario22

Congo Square, New Orleans (img from web).  https://en.m.wikipedia.org/wiki/Congo_Square

Una senz'altro immaginifica transizione di un sistema anch'esso senz'altro immaginifico "3vs3 palle" 

https://flashontrack.blogspot.com/2022/10/life-proposito-di-bizzarri-scenari-qui.html

qui potrebbe verificarsi una improvvisa mutazione "3vs3" verso un sistema auto- riconfigurato in "4vs2" palle.

(-) In prima approx il sistema destrogiro "4palle", sebbene caotico,  quasisticastico, potrebbe dimostrare chance di creativa stabilizzazione, anche a medio-lungo termine, anche grazie a non del tutto improbabili episodi di drammatiche funzionali fagocitosi (e.g. nelle forme predatorie del cannibalismo/ auto- cannibalismo, anche orgiastico estremo) al proprio interno.

(-) Il sistema levogiro "2palle" potrebbe invece lui medesimo risultare vincente sull'altro destrogiro nel caso riuscisse nell'im.probabile stabilizzazione,  ristrutturazione funzionale - dimostrando pubblicamente non banali capacità di risoluzione/ reimpostazione di problemi - perciò animandosi in modalità attrattive, coagulative su una parte significativa del 50% di quelle moltitudini verosimilmente costituite da entità fluttuanti nella solitaria condizione di pulviscoli erratici in emarginata sublimazione.

L'immagini, senz'altro campate in aria purtuttavia intriganti:  'episodi di drammatiche funzionali fagocitosi', 'cannibalismo, auto-cannibalismo anche orgiastico estremo' e 'solitaria condizione di pulviscoli erratici in emarginata sublimazione' meriterebbero una serie di poetiche, quasistocastiche perfino

# gst: vortex-pair dance and oscillation

       Fig. 4

This AA study << focuses on fundamental dynamics of vortex-pair fields, specifically known as vortex-pair beams (VPBs) in optics. VPBs have gained increasing attention due to their unique properties, including vortex attraction and repulsion. Here, (AA)  explore the dynamics of pure-phase VPBs (PPVPBs) and observe intriguing helical and intertwined behaviors of vortices, resembling a vortex-pair dance. >>

They << uncover the oscillation property of the intervortex distance for PPVPBs in free space. The observed dancing and oscillation phenomena are intricately tied to the initial intervortex distance and can be explained well in the hydrodynamic picture. Notably, the vortex dancing and oscillation alter the process of vortex-pair annihilation, extending the survival range for opposite vortices. >>

<< This discovery enhances our understanding of vortex interactions and sheds light on the intricate dynamics of both vortex-vortex and vortex-antivortex interactions. >>

<< Wearing more formal clothing was associated with higher action identification level (Study 1) and greater category inclusiveness (Study 2). Putting on formal clothing induced greater category inclusiveness (Study 3) and enhanced a global processing advantage (Study 4). The association between clothing formality and abstract processing was mediated by felt power (Study 5). The findings demonstrate that the nature of an everyday and ecologically valid experience, the clothing worn, influences cognition broadly, impacting the processing style that changes how objects, people, and events are construed. >>

# behav: adaptive synchronizations; the tendency to anticipate during auditory rhythms

<< Dancing and playing music require people to coordinate actions with auditory rhythms. In laboratory perception-action coordination tasks, people are asked to synchronize taps with a metronome. When synchronizing with a metronome, people tend to anticipate stimulus onsets, tapping slightly before the stimulus. The anticipation tendency increases with longer stimulus periods of up to 3500ms, but is less pronounced in trained individuals like musicians compared to non-musicians.  >>

# gst: apropos of dances, drops that dance following snake- and ouroboros-shaped trajectories on lubricated surfaces.

<< Recently, (AA) observed a curious breath figure pattern when water condenses on solid surfaces coated with a thin lubricant oil film. Water drops of various sizes, ranging from tens of microns to several millimetres, start to perform a self-avoiding, serpentinelike dance. As the drop moves, it consumes smaller droplets along its path, converting interfacial energy into kinetic energy to sustain its motion. These self-avoiding drops preferentially avoid crossing their own paths as well as the paths of other drops; they can only intersect their previous paths once sufficient recondensation has occurred. This self-avoiding behavior arises because the previous path (..) contains little to no water content to fuel self-propulsion, so the drops continually seek areas with higher local water content. >>️

<< This intricate serpentine dance is driven by short-range interactions between droplets, mediated by overlapping menisci, similar to the Cheerios effect. Remarkably, long-range order spontaneously emerges from these short-range interactions, with the collective motion exhibiting self-similarity—breath figure patterns appear roughly similar across different scales. >>

<< The serpentine motions of the drops, which can span distances many times their diameters, eventually deplete the local lubricant film, causing a transition from serpentine to circular motion. This circular motion can be seen as a unique form of serpentine motion occurring in lubricant-poor regions. As the drops move, they continually redistribute the lubricant across the substrate, leading to a dynamic interplay between serpentine and circular motions. This ongoing redistribution can be visualized by illuminating the surface with diffused white light and capturing the resulting interference patterns with a digital camera. Variations in lubricant thickness produce different hues, creating a vibrant, colorful canvas and an intricate dance floor for the condensing drops. >>️

<< The phenomenon described in (AA) paper represents a fascinating example of active matter driven by condensation, rather than the more commonly observed chemical reactions or Marangoni effects. >>

Apropos of 'homoclinic orbits' ...

<< the reinjection of the departing trajectories in the vicinity of an unstable fixed point of the saddle-focus type [..] is frequently associated with the emergence of orbits of a rather exceptional type known as 'homoclinic orbits'. These are trajectories that leave the fixed point but come back to it; in other words, they tend to the same limit when time t goes to +∞ as well as to -∞ . [..]. Homoclinic orbits are very sensitive to variation of parameter [parms] values and are generally destroyed if the [parms] do not satisfy a strict equality (in the terminology of [..] they are structurally unstable). However, for nearby values of the [parms] their disappearance leaves a very rich structure of orbit in phase space, some of which behave chaotically. >>️
