# game: pulsating as a Toffoli gate: Parrondo's paradox with a three-state coin (heads, tails, and a side)

<< Parrondo's paradox - an apparent paradox in which two losing strategies combine to make a winning strategy - can emerge as a coin game with a single coin in the quantum realm, but only when the coin has three states (heads, tails, and a side) rather than the conventional two. >>

<< In the new study, [AA] have demonstrated a Parrondo's game using a three-state coin, which they represent with a qutrit, a quantum system with three states. >>

quando lessi per la prima volta in bibliografia circa il "Parrondo Game"  mi venne in mente una strategia che avevo immaginato e piu' volte usato a suo tempo - da meta'  anni '70 a tutti gli anni '80 (e oltre) - composta da una sorta di "tit-for-tat stocastico" cioe' una strategia di gioco di  "cooperazione/ defezione" con decisioni di scelta pilotate da "lancio di moneta" all'interno di due (e poi anche tre) scenari riconducibili al tipo Parrondo ... in pratica la generazione di scenari senz'altro di  "frontiera", evolutivi,  immediatamente generabili all'interno di situazioni (se-si-puo-dire ... or, namely, "sire-die-soup") del tipo "standard", supposte "lineari".  Anzicheforse.

# phys: a holographic image of a black hole

<< by applying a magnetic field to a small, irregularly shaped graphene flake, the flake becomes a quantum hologram of a black hole. This means that the graphene flake recreates the spatial structure and characteristic properties of a black hole, but in a much smaller, lower-dimensional system. >>

<< The type of holographic duality illustrated by the SYK [Sachdev-Ye-Kitaev] model is particularly interesting because it exhibits some of the signature properties of black holes, such as non-zero residual entropy and quantum chaos propagation. >>

# trade: job career quick transitions, from Silicon Valley to the Cannabis Marketplace

<< For decades, those looking to change the world arrived in Silicon Valley seeking the latest frontier: social media companies, gadget makers, delivery and transportation apps, e-commerce platforms. >>

<< But as the emerging markets of yesterday become today's stalwarts, a growing number of technology workers are migrating to an even newer sector-so new that it isn't legal at the federal level. >>

<<  The U.S. cannabis market is expected to grow to $75 billion in sales by 2030 from $10 billion, said Troy Dayton, chief executive of cannabis investment and market research firm Arcview. >>

<< Eaze, which aspires to be something of an Amazon for pot, has raised more than $50 million from tech investors such as DCM and Fresh VC. PAX Labs, whose cannabis vaporizers resemble Apple gadgets, has raised more than $100 million from Silicon Valley and institutional investors. And Baker Technologies, which is essentially a Salesforce for dispensaries, made it into 500 Startups' prestigious accelerator program in 2015. >>

# behav: social isolation vs. evolutionary dynamics

<< For some animals—such as beetles, ants, toads, and primates—short-term social isolation can be just as vital as social interaction to development and long-term evolution. In a review published July 17 in the journal Trends in Ecology & Evolution, two evolutionary biologists describe approaches for testing how an animal's isolation might impact natural selection and evolution. >>

AA << suggest that the 'index of social isolation', the mismatch between actual and optimal social interaction experienced by individuals within a population, may play a key role in releasing cryptic genetic variation, adaptation rates, diversification patterns, and ecosystem-level processes. Evolutionary dynamics arising from social isolation could have significant impacts in applied settings such as conservation, animal breeding, control of biological invasions, and evolutionary resilience to anthropogenic change. >>
