# life: landing on a swinging perch: peach-faced lovebirds (Agapornis roseicollis) prefer extremes.

<< Birds frequently must land safely and accurately on moving branches or power lines, and seemingly accomplish such maneuvers with acrobatic precision. To examine how birds target and land successfully on moving supports, (AA) investigated how peach-faced lovebirds (Agapornis roseicollis) approach and land on a swinging perch.  >>️

<< In support of (AA) hypothesis for stable landings, lovebirds timed their landings in a majority of trials (51.3%), when the perch was approaching either extreme of its motion with its velocity nearing zero (27.5% in the same direction as the bird’s approach – SDs, and 23.8% in the opposite direction to the bird’s approach – ODs). As a result, lovebirds exhibited a robust bimodal strategy for timing their landing to the phase of the swinging perch. Less commonly, lovebirds landed when the perch was moving at high velocity either toward the bird’s approach (12.3%) or in the same direction as the bird’s approach (11.5%); with the remainder (21.9%) of trials distributed over a broad range of swing phases. >>️

# 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

<< Hello! Today: new research is shining a light on how our brains flit between states of stability and chaos, depending on what we’re doing. >>

<< Our brains exist in a state somewhere between stability and chaos as they help us make sense of the world, according to recordings of brain activity taken from volunteers over the course of a week. >>

<< As we go from reading a book to chatting with a friend, for example, our brains shift from one semi-stable state to another—but only after chaotically zipping through multiple other states in a pattern that looks completely random. >>

<< Understanding how our brains restore some degree of stability after chaos could help us work out how to treat disorders at either end of this spectrum. Too much chaos is probably what happens when a person has a seizure, whereas too much stability might leave a person comatose. >>

# 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.

# gst: like steering a marble through a tilting labyrinth, randomness seems to quickly deliver specific outcomes.

<< According to the infinite monkey theorem, a monkey randomly hitting the keys of a typewriter will eventually write something worth reading—but it might take a few trillion years of trying. For those lacking the patience to wait, (AA)  now show that randomness can deliver specific outcomes much more quickly.  Simulating a 2D nanocluster of a dozen particles, (they) determine the temperature at which thermal fluctuations can most quickly rearrange those particles into a predetermined shape. They find that this time can be dramatically cut by applying an appropriate macroscopic force to the particles. >>

<< The duo also simulated nanoclusters that were subject to a macroscopic force field, for example, metallic nanoparticles in an electric field. Like steering a marble through a tilting labyrinth, they found the optimal global force to apply at each iteration such that the nanocluster navigated the space of possible configurations several orders of magnitude more quickly. >>️️

# life: aproposito di '1or2achoos' (da Wuhan (?)) ...

a proposito di '1or2achoos' (da Wuhan (?)) ... cfr Weekly epidemiological update on COVID-19 - 6 July 2022. Edition 99. Emergency Situational Updates. https://www.who.int/publications/m/item/weekly-epidemiological-update-on-covid-19---6-july-2022   img   https://cdn.who.int/media/images/default-source/mca/mca-covid-19/coronavirus-2.tmb-768v.jpg?sfvrsn=4dba955c_12 

Qui l'approccio semplice, diretto, efficace che ho usato per la prevenzione ed eventuale gestione personale dell'entità coronavirus /  SARS-COV-2 (SARS: Severe Acute Respiratory Syndrome ) 

In data 20 Marzo 2020 ho pubblicato sul mio blog FonT - e, giusto per intendersi, ho contemporaneamente inviato il testo a una mia mail criptata - un approccio nell'ipotesi di disattivare / spegnere il coronavirus (sars-cov-2) che causa covid-19;   

Qui il link   ('you can get more security by spraying...)'   https://flashontrack.blogspot.com/2020/03/life-funky-immediate-approach-of.html

L'approccio pubblicato consisteva nell'uso di una soluzione di alcool (uso alimentare, 96%), perossido di idrogeno (3%) e acqua da nebulizzare con un generico dosatore spray tascabile (usato per nebulizzare profumi); 

La stechiometria di due dei tre componenti (alcool e perossido di idrogeno) era indicata sul sito del WHO (e consigliata per disinfettare superfici);

Qui il link attuale del doc 

12 WHO-recommended handrub formulations (2009) - Formulation I      

https://www.ncbi.nlm.nih.gov/books/NBK144054  che a quel tempo era presente, e attualmente assente, sul sito WHO al link 

https://www.who.int/infection-prevention/tools/hand-hygiene/handrub-formulations/en  

e scaricabile nella forma di doc.pdf

https://www.who.int/gpsc/5may/Guide_to_Local_Production.pdf  

Modificai la soluzione con la sostituzione di glicerolo con acqua per consentire la nebulizzazione del prodotto; 

Da allora ho sempre usato la miscela spray per disinfettare mani e mascherine di cotone (doppia mascherina, di cotone, riusabile, in posizione esterna e quando disponibile ffp2 in posizione interna); 

Tuttavia ho usato la stessa miscela per trattare i tre 'flu' (ipoteticamente covid-19) che ho contratto nei tre anni 2020, 2021 e 2022.  

In particolare, tutte le volte che ho avuto necessità di soffiare il naso (per secrezione mucosa, causa rinorrea) ho successivamente trattato entrambi naso e gola con la miscela spray; direttamente sulla mucosa orale e indirettamente nella mucosa nasale inspirando la soluzione preventivamente nebulizzata sul dorso della mano;

Nei primi due casi (2020 e 2021) ho spento il 'flu' in mezza giornata (in entrambe le situazioni non ero vaccinato); nel terzo caso ho spento il 'flu' in 2 giorni scarsi di trattamento (ero già stato vaccinato con le 2+1 dosi perchè obbligatorie in Italia specialmente per chi era iscritto all'Ordine dei Biologi e comunque per chi aveva raggiunto l'età di 50+ anni  

( OMS - Piano vaccini anti Covid-19

https://www.salute.gov.it/ )

I flu precedenti al 2020 (circa 60 flu nell'arco di 70 anni di età, a ciclicità annuale) mi avevano sempre impegnato in circa tre giorni di pre- crisi, tre giorni di crisi a letto e tre giorni di post- crisi (convalescenza) per un totale di mai meno di quattro-cinque giorni di parziale compromissione dell'autonomia; 

Nelle mie tre individuali esperienze, confrontate con tutte le pregresse, l'immunità sembra essere stata quasi immediata, senza alcuna compromissione dell'autonomia.

Se (beninteso, se e solo se) le future risposte individuali del mio sistema immunitario alle future probabili ondate epidemiche da flu opp sars saranno equivalenti alle tre citate sopra, per quello che mi riguarda questa problematica si è chiusa a far data dal 20 marzo 2020, indipendentemente dalle future disponibilità di vaccini anti-flu anti-sars. 

Qui l'ipotetico meccanismo di azione.

I coronavirus (come i virus flu a causa di orthomyxoviridae) si duplicano nelle mucose orale e nasale; il capside virale ( e.g. Chung-ke Chang et al. Antiviral Res. 2014 Mar. https://pubmed.ncbi.nlm.nih.gov/24418573/ ) in presenza di alcool probabilmente si apre per denaturazione proteica e questo consente a un sistema immunitario fisiologicamente attivo di leggere sia il capside (che dovrebbe comunque conservare la struttura primaria) sia parti della sua metameccanica molecolare interna;

# gst: synchronous dynamics by uncorrelated noise

<< Synchronization is a widespread phenomenon observed in physical, biological, and social networks, which persists even under the influence of strong noise. Previous research on oscillators subject to common noise has shown that noise can actually facilitate synchronization, as correlations in the dynamics can be inherited from the noise itself. However, in many spatially distributed networks, such as the mammalian circadian system, the noise that different oscillators experience can be effectively uncorrelated. >>️

<< Here, (AA) show that uncorrelated noise can in fact enhance synchronization when the oscillators are coupled. Strikingly, (their) analysis also shows that uncorrelated noise can be more effective than common noise in enhancing synchronization. >>️

# blues; New Moon Jelly Roll Freedom Rockers. Vol. 1 (Stony Plain). Sep 4, 2020.

<< In 2007, while rolling through the American night in a ramshackle retirement home vehicle badly disguised as a tour bus, blues legend Charlie Musselwhite and North Mississippi Allstars' guitarist Luther Dickinson engaged in conversation. The younger man related Alvin Youngblood Hart's philosophical desire to live as a "freedom rocker." The wily elder bluesman listened to his words, then looked out the window and knowingly pointed at the rising moon. He replied: "New Moon Freedom Rockers." Back in Mississippi at the Zebra Ranch studio, Musselwhite and Cody and Luther Dickinson joined forces with their dad, roots rock legend Jim Dickinson (who promptly added the words "Jelly Roll" to the band's name), Alvin Hart, and Jimbo Mathus, with NMA bassist Chris Chew and Paul Taylor as guests. They circled chairs, placed mikes, and hit "record." Afterwards, the session tapes were archived. They sat in the vault until Jim Dickinson passed in 2009, and they became apocryphal. Stony Plain's Holger Peterson contacted Luther and Cody about releasing them. >>

AA << discovered that simple shifts in gene activity in the leaf bud provide a flexible mechanism for how leaves of all shapes and sizes are made. >>

<< We've discovered a general principle by which leaves from flat sheets to needle-like and curved shapes are formed,  (..) We found that the complex leaf shapes of carnivorous plants evolved from species with flat leaves through simple shifts in gene activity in the leaf bud. What surprised us is that how such a simple mechanism could underlie such a wide diversity of leaf shapes.  (..) If you want to understand why water boils at 100°C, look for situations in which it doesn't, like the top of Mount Everest where it boils at 70°C. From that we learn the general principle that boiling point depends on air pressure. Similarly, if you want to understand why most leaves are flat, you might study exceptions, like the leaves of some carnivorous plants which form pitchers to trap prey, >> Enrico Coen.

AA << report that, if the magnitudes of the black hole spins are allowed to extend to high values, the effective spins for these systems indicate a 0.015 odds ratio against an aligned angular distribution compared to an isotropic one [isotropic spin orientation: the spins of the black holes are randomly oriented with respect to the orbit of the binary system]. When considering the effect of ten additional detections, this odds ratio decreases to 2.9 × 10−7 against alignment >>
