Dynamic flat lens with metasurface actuated with MEMS - 2 views

  •  
    Great engineering feat from Capasso's idea - an integrated flat lens electrically controlled enabling dynamic beam steering. Reconfigurabilility is the aim. The lens can be used microscope systems, holographic and projection imaging, LIDAR and laser printing. Besides working now on the mid-IR, visible light is the target.

AI racks up insane high scores after finding bug in ancient video game * The Register - 2 views

  •  
    Evolutionary Strategies are able to explore broader areas of the search space than reinforcement learning techniques. Thus, they are able to encounter strange bugs resulting in large rewards.

Alibaba's AI Outguns Humans in Reading Test - Bloomberg - 4 views

  •  
    any papers or insights on methods available?
  •  
    Couldn't find a paper for Alibaba's results but Microsoft Research's performance on this dataset was very close. The paper is here: https://www.microsoft.com/en-us/research/wp-content/uploads/2017/05/r-net.pdf Btw the 'reading test' is a publicly available dataset called 'Stanford Question Answering Dataset (SQuAD)'. Their website shows a leaderboard: https://rajpurkar.github.io/SQuAD-explorer/

Synthesis of Carbon Nanofibres direct from CO2 atmosphere - 9 views

  •  
    It may be feasible to use this in the Marsian atmosphere (9mbar CO2) to directly grow Carbon Nanofibres for infrastructural needs

    This is clearly interesting for the new YGT on Space Architecture (with background on fabrics) that comes in October. Since I was asked to provide input here, this could be a solid ground to start with. Thanks. :)
  •  
    nice!

    gave it to Hanna, she is looking into it now. Manchester and Ghent University could be potential collaborators.

An AI physicist can derive the natural laws of imagined universes - 1 views

  •  
    I'm afraid I take some issue with this rather glorious title. I've only skimmed this paper but looking at the experimental details, their 'imagined universes' comprise of a ball confined in a 2D space as well as a double pendulum. Work along this area is nothing new - it's known in the control community as Inverse Reinforcement Learning - learning dynamics of some system from demonstration trajectories. The paper title ('Toward an AI Physicist for Unsupervised Learning') is more moderate so yet again the issue is how AI is reported in the media...

Quantum Artificial Life in an IBM Quantum Computer - 6 views

  •  
    I tried reading the abstract and my eyes glazed over at the buzzword density. Is this hot doo doo or a meaningful result?
  •  
    wow, quantum, artificial life, biomimetic, quantum supremacy .... quantum machine learning, and quantum artificial intelligence and, wait for it ...... quantum complexity. All in one abstract is this the new champion?

Demonstrating a new technology for space debris removal using a bi-directional plasma t... - 2 views

  •  
    Some people answering the question 'What's cooler than blasting space debris with lasers...?'.
  •  
    If it fires in both directions, can we align it such that it deorbits two debris with one shot?
  •  
    :) the idea of having this method for debris removal is actually an ACT one from Claudio Bombardelli (ACT RF in MAD https://en.wikipedia.org/wiki/Ion-beam_shepherd). This is just a technological device to implement it so that the system on board is simplified (i.e. instead of two engines, you get away with one and a weird nozzle) Marcus, you cannot align it to get rid of two debris as you need to keep the spacecraft close to the debris as this is a long duration acion. One of the two would drift away (can only follow one!)

Scientists plan huge European AI hub to compete with US - 1 views

  •  
    "Leading scientists have drawn up plans for a vast multinational European institute devoted to world-class artificial intelligence (AI) research in a desperate bid to nurture and retain top talent in Europe. The new institute would be set up for similar reasons as Cern, the particle physics lab near Geneva, which was created after the second world war to rebuild European physics and reverse the brain drain of the brightest and best scientists to the US."

Smallest transistor with 1-nanometer carbon nanotube gate - 0 views

  •  
    Amazing engineering feat: 1 nm transistor. Besides we can argue Moore law is still OK, dennard scaling is gone and with it the performance boost, as alluded subtly. Link article: http://science.sciencemag.org/content/354/6308/99.full

To Sleep, Perchance to Clean - University of Rochester Medical Center - 2 views

  •  
    Why do we sleep? One answer could be: to clear waste products accumulated during the day. To prevent aging and neurodegeneration, the body must maintain homeostasis. What would happen if we experience chronic sleep loss? What would happen if microgravity impairs the cerebrospinal fluid to flush the brain? What would happen if cosmic radiations increase the amount of daily waste products?
