Quantum effects help minimize communication flaws - 0 views

  •  
    Noise limits the performance of modern quantum technologies. However, particles traveling in a superposition of paths can bypass noise in communication. A collaboration between the Universities of Hong-Kong, Grenoble and Vienna, as well as the Austrian Academy of Sciences, under the lead of Philip Walther, reveals novel techniques to reduce noise in quantum communication. The results, published in the latest issue of Physical Review Research, demonstrate that quantum particles traveling in a superposition of paths enable noise reduction in communications.

Why capitalism is in constant conflict with democracy - 0 views

  •  
    The capitalist economic system has always had a big problem with politics in societies with universal suffrage. Anticipating that, most capitalists opposed and long resisted extending suffrage beyond the rich who possessed capital. Only mass pressures from below forced repeated extensions of voting rights until universal suffrage was achieved-at least legally. To this day, capitalists develop and apply all sorts of legal and illegal mechanisms to limit and constrain suffrage. Among those committed to conserving capitalism, fear of universal suffrage runs deep. Trump and his Republicans exemplify and act on that fear as the 2020 election looms.

Physicists offer a new 'spin' on memory - 0 views

  •  
    Unlike conventional micro-transistors, magnetic tunnel junctions don't use the electrical charge of electrons to store information, but take advantage of a quantum-mechanical property that electrons have, which is referred to as "spin." Known as spintronics, computing technology based on magnetic tunnel junctions is still very much in the experimental phase, and applications are extremely limited. For example, the technology is used in aircraft and slot machines to protect stored data from sudden power outages. This is possible because magnetic tunnel junctions process and store information by switching the orientation of nano-scale magnets instead of moving electrons around as regular transistors do.

Gaps in early surveillance of coronavirus led to record-breaking US trajectory: study - 0 views

  •  
    Research from the University of Notre Dame estimates that more than 100,000 people were already infected with COVID-19 by early March-when only 1,514 cases and 39 deaths had been officially reported and before a national emergency was declared. The study provides insight into how limited testing and gaps in surveillance during the initial phase of the epidemic resulted in so many cases going undetected. The study was published in the Proceedings of the National Academy of Sciences.

Diverse interactions and ecosystem engineering can stabilize community assembly | Natur... - 0 views

  •  
    The complexity of an ecological community can be distilled into a network, where diverse interactions connect species in a web of dependencies. Species interact directly with each other and indirectly through environmental effects, however to our knowledge the role of these ecosystem engineers has not been considered in ecological network models. Here we explore the dynamics of ecosystem assembly, where species colonization and extinction depends on the constraints imposed by trophic, service, and engineering dependencies. We show that our assembly model reproduces many key features of ecological systems, such as the role of generalists during assembly, realistic maximum trophic levels, and increased nestedness with mutualistic interactions. We find that ecosystem engineering has large and nonlinear effects on extinction rates. While small numbers of engineers reduce stability by increasing primary extinctions, larger numbers of engineers increase stability by reducing primary extinctions and extinction cascade magnitude. Our results suggest that ecological engineers may enhance community diversity while increasing persistence by facilitating colonization and limiting competitive exclusion.

Case Series of Multisystem Inflammatory Syndrome in Adults Associated with SARS-CoV-2 I... - 0 views

  •  
    Clinical suspicion and indicated SARS-CoV-2 testing, including antibody testing, might be needed to recognize and treat adults with MIS-A. Further research is needed to understand the pathogenesis and long-term effects of this condition. Ultimately, the recognition of MIS-A reinforces the need for prevention efforts to limit spread of SARS-CoV-2. COVID-19

The future is mixed-race and that's a good thing for humanity | Aeon Essays - 0 views

  • If the history of life on Earth can teach us anything, it is this: as conditions change, species either adapt or become extinct. In our time of considerable environmental change, humanity should consider its options. No species, even the almighty Homo sapiens, can stop evolution completely. But we can choose to limit our capacity for ongoing biological adaptation in an effort to remain ever the same by keeping populations isolated. Of course, such decisions are not made by humanity as a whole but by individuals and governments. Nationalism and xenophobia, on the rise in the US and Europe, threaten to decrease genetic exchange between populations, stifling our ability to continue evolving and adapting.Alternatively, we can embrace immigration and globalisation in an effort to position ourselves for a brighter future.

Who Benefits From Trump's Chaos? | New Republic - 0 views

  • Each of them had their own, often conflicting agendas. But creating or sustaining fear requires elites to share neither unity of purpose nor identity of interest. It merely requires that they cooperate—despite their differences, or because of them. After all, elites possess particular kinds of power, housed in particular institutions, and they lead different constituencies. These particularities and differences make their power local and limited. To be truly effective, they must combine their power, doing together what each cannot do alone.

What does home mean if your bed is on the pavements of Paris? | Aeon Essays - 0 views

  • The American anthropologist Edward Fischer, paraphrasing Aristotle, said that the good life is ‘a life worth living’, or a journey towards ‘a fulfilled life’. It has to do with happiness but is not limited to it; it’s often – perhaps counterintuitively – linked to commitment and sacrifice, to the work of becoming a particular person. The French philosopher Michel Foucault in 1982 described these practices as technologies of the self. According to Foucault, the self is ‘not given to us … we have to create ourselves as a work of art’. My informants on the streets of Paris were striving – in their own ways – towards being better selves. I came to understand the activities, processes and routines that they engaged in – begging, making a shelter, accessing temporary housing, etc – as practices of the self geared towards a better life, as practices of homemaking on the street, as practices of hope.
  • Aside from François, others I met on the streets of Paris – such as Sabal from India, and Alex from Kosovo – talked about their engagement in such practices of hope. Following them through soup kitchens, drop-in centres, government institutions and homeless shelters, I observed two main ways in which they attempted to push for a better life. Both of them were connected to the idea of home: my informants in Paris were longing to find and go back to a homeland, often one from the past, while on a daily basis they were struggling to construct a home in order to survive. That was what a better life looked like for them.
  • Home, according to the Australian social scientist Shelley Mallett, is always suspended between the ideal and the real. It relates to ‘the activity performed by, with or in person’s things and places. Home is lived in the tension between the given and the chosen, then and now.’ While Sabal’s India was part of the ideal, what Alex was dealing with was closer to the ‘real’ side of this distinction. His home-making efforts were a continuous process of daily activities.

  • For many of the homeless people I’ve met in both London and Paris, home was connected to a place they departed from and have a desire to return to – a place that carried what the English sociologist Liz Kenyon calls a right to return and a sense of one’s origin. Sara Ahmed’s 1999 study of migrants’ writing, particularly Asian women living in Britain, supports this view of home as something in the longer-term future. The British-Australian scholar wrote that home is often a destination, somewhere to travel to: ‘the space which is most like home, which is most comfortable and familiar, is not the space of inhabitance – I am here – but the very space in which one finds the self as almost, but not quite, at home. In such a space, the subject has a destination, an itinerary, indeed a future, but in having such as destination, has not yet arrived.’ Home is, in this sense, not about the present – and surely not a place of passive suffering – but about one’s hopes, about making home an imagined place where one has not yet arrived.
  • Home is exactly such a process, involving the material and the imaginative, social connections and mundane acts. Routines, habits and rhythms – often as simple as regularly visiting certain neighbourhoods, shelters and food kitchens – are important parts of this process, and are deeply connected to a temporal as well as spatial order. This focus on order is best expressed in the classical analysis of home by the English anthropologist Mary Douglas:[Home] is always a localisable idea. Home is located in space but it is not necessarily a fixed space. It does not need bricks and mortar, it can be a wagon, a caravan, a board, or a tent. It need not be a large space, but space there must be, for home starts by bringing some space under control.
  • François, who introduced me to the labour of begging, found something close to home in his daily practices. His home was fashioned by coming face to face with the city around him. These narratives show how far removed these people are from a state of passive suffering. Yes, there were moments of idleness and, for some, long phases of pain. But most of the people I met sleeping rough – independent of age, gender, tenure on the street and level of addiction – were striving, in their way, towards a better life: first on, and hopefully off, the street.

The idea of intellectual property is nonsensical and pernicious - Samir Chopra | Aeon E... - 0 views

  • A general term is useful only if it subsumes related concepts in such a way that semantic value is added. If our comprehension is not increased by our chosen generalised term, then we shouldn’t use it. A common claim such as ‘they stole my intellectual property’ is singularly uninformative, since the general term ‘intellectual property’ obscures more than it illuminates. If copyright infringement is alleged, we try to identify the copyrightable concrete expression, the nature of the infringement and so on. If patent infringement is alleged, we check another set of conditions (does the ‘new’ invention replicate the design of the older one?), and so on for trademarks (does the offending symbol substantially and misleadingly resemble the protected trademark?) and trade secrets (did the enterprise attempt to keep supposedly protected information secret?) The use of the general term ‘intellectual property’ tells us precisely nothing.
  • Property is a legally constructed, historically contingent, social fact. It is founded on economic and social imperatives to distribute and manage material resources – and, thus, wealth and power. As the preface to a legal textbook puts it, legal systems of property ‘confer benefits and impose burdens’ on owners and nonowners respectively. Law defines property. It circumscribes the conditions under which legal subjects may acquire, and properly use and dispose of their property and that of others. It makes concrete the ‘natural right’ of holding property. Different sets of rules create systems with varying allocations of power for owners and others. Some grants of property rights lock in, preserve and reinforce existing relations of race, class or gender, stratifying society and creating new, entrenched, propertied classes. Law makes property part of our socially constructed reality, reconfigurable if social needs change.
  • ‘Property’ is a legal term with overwhelming emotive, expressive and rhetorical impact. It is regarded as the foundation of a culture and as the foundation of an economic system. It pervades our moral sense, our normative order. It has ideological weight and propaganda value. To use the term ‘intellectual property’ is to partake of property’s expressive impact in an economic and political order constructed by property’s legal rights. It is to suggest that if property is at play, then it can be stolen, and therefore must be protected with the same zeal that the homeowner guards her home against invaders and thieves.

  • What about the common objection that without ‘intellectual property’ the proverbial starving artist would be at the mercy of giant corporations, who have existing market share and first-mover advantage? It is important to disaggregate the necessity and desirability of the protections of the various legal regimes of copyright, patents, trademarks and trade secrets from that of the language of ‘intellectual property’. Current copyright, patent, trade-secret and trademark law do not need to be completely rejected. Their aims are rather more modest: the reconfiguration of legal rules and protections in an economy and culture in which the nature of creative goods and how they are made, used, shared, modified and distributed has changed. Such advocacy is not against, for instance, copyright protections. Indeed, in the domain of free and open-source software, it is copyright law – through the use of artfully configured software licences that do not restrain users in the way that traditional proprietary software licences do – that protects developers and users. And neither do copyright reformers argue that plagiarists be somehow rewarded; they do not advocate that anyone should be able to take a copyrighted work, put their name on it, and sell it.
  • This public domain is ours to draw upon for future use. The granting of temporary leases to various landlords to extract monopoly rent should be recognised for what it is: a limited privilege for our benefit. The use of ‘intellectual property’ is a rhetorical move by one partner in this conversation, the one owning the supposed ‘property right’. There is no need for us to play along, to confuse one kind of property with another or, for that matter, to even consider the latter kind of object any kind of property at all. Doing so will not dismantle the elaborate structures of rules we have built in order to incentivise artistic and scientific work. Rather, it will make it possible for that work to continue.

Toward Democratic, Lawful Citizenship for AIs, Robots, and Corporations - 0 views

  • If an AI canread the laws of a country (its Constitution and then relevant portions of the legal code)answer common-sense questions about these lawswhen presented with textual descriptions or videos of real-life situations, explain roughly what the laws imply about these situationsthen this AI has the level of understanding needed to manage the rights and responsibilities of citizenship.
  • AI citizens would also presumably have responsibilities similar to those of human citizens, though perhaps with appropriate variations. Clearly, AI citizens would have tax obligations (and corporations already pay taxes, obviously, even though they are not considered autonomous citizens). If they also served on jury duty, this could be interesting, as they might provide a quite different perspective to human citizens. There is a great deal to be fleshed out here.
  • The question becomes: What kind of test can we give to validate that the AI really understands the Constitution, as opposed to just parroting back answers in a shallow but accurate way?
  • ...2 more annotations...
  • So we can say that passing a well-crafted AI Citizenship Test would bea sufficient condition for possessing a high level of human-like general intelligenceNOT a necessary condition for possessing a high level of general intelligence; nor even a necessary condition for possessing a high level of human-like general intelligenceNOT a sufficient condition for possessing precisely human-like intelligence (as required by the Turing Test or other similar tests)These limitations, however, do not make the notion of an AI Citizenship less interesting; in a way, they make it more interesting. What they tell us is: An AI Citizenship Test will be a specific type of general intelligence test that is specifically relevant to key aspects of modern society.

New AI system will help us discover the most effective behaviour change strategies - 0 views

  • hanging people’s behaviour is key to tackling the world’s health, social and environmental problems, such as obesity, sustainable living and cybersecurity. To change behaviour, though, we need to know what works, for whom, where and how. But research is generated far faster than humans can access and use it. A search on Google Scholar for “behaviour change” produced over 60,000 hits for the first six months of 2018. Evidence on behaviour change interventions is also messy. Different terms are often used to describe similar things – “physical activity” and “exercise”, for example. This means different people can often mean different things when discussing or researching behaviour change. This lack of shared vocabulary limits our progress in discovering what interventions work best.

Can Sustainable Agriculture Survive Under Capitalism? - 0 views

  • One problem is the price of the produce. Many of us have had the experience of turning up at our local farmers' market, armed with tote bags, only to slink back to the supermarket after seeing the prices of the vegetables on offer. This is hardly the fault of the individual farmers. Still, as Pilgeram points out in a paper that she published in 2011, the costs involved with running such an operation mean that the benefits are inevitably affordable only to a small (generally white and middle-class) portion of society.
  • But it's a limited victory, Pilgeram writes in her most recent paper, published in November of 2018, and empowers only a certain class of women "while leaving [the capitalist] system basically entirely unaffected"—and which also risks gentrifying the towns to which these farmers move, further entrenching the country's class divide.
  • "The economic system that we have in place makes it impossible, really, to create a socially just food system. It's not possible under capitalism," Pilgeram says. Without a drastic change to this system, sustainable agriculture risks becoming an "esoteric side note" to conventional agriculture, she adds—or simply another way for those with money to live healthier lives than those without.

I am a data factory (and so are you) - 0 views

  • Data is no less a form of common property than oil or soil or copper. We make data together, and we make it meaningful together, but its value is currently captured by the companies that own it. We find ourselves in the position of a colonized country, our resources extracted to fill faraway pockets. Wealth that belongs to the many — wealth that could help feed, educate, house and heal people — is used to enrich the few. The solution is to take up the template of resource nationalism, and nationalize our data reserves.
  • Emphasising time well spent means creating a Facebook that prioritises data-rich personal interactions that Facebook can use to make a more engaging platform. Rather than spending a lot of time doing things that Facebook doesn’t find valuable – such as watching viral videos – you can spend a bit less time, but spend it doing things that Facebook does find valuable. In other words, “time well spent” means Facebook can monetise more efficiently. It can prioritise the intensity of data extraction over its extensiveness. This is a wise business move, disguised as a concession to critics. Shifting to this model not only sidesteps concerns about tech addiction – it also acknowledges certain basic limits to Facebook’s current growth model. There are only so many hours in the day. Facebook can’t keep prioritising total time spent – it has to extract more value from less time.
  • But let’s assume that our vast data collective is secure, well managed, and put to purely democratic ends. The shift of data ownership from the private to the public sector may well succeed in reducing the economic power of Silicon Valley, but what it would also do is reinforce and indeed institutionalize Silicon Valley’s computationalist ideology, with its foundational, Taylorist belief that, at a personal and collective level, humanity can and should be optimized through better programming. The ethos and incentives of constant surveillance would become even more deeply embedded in our lives, as we take on the roles of both the watched and the watcher. Consumer, track thyself! And, even with such a shift in ownership, we’d still confront the fraught issues of design, manipulation, and agency.
