A New Spin on Electronics - 0 views

shared by pacome delva on 26 Nov 09 - Cached
  • Incorporating both the magnetic leads and the underlying semiconductor, a spintronics circuit could hold its memory when turned off, as the magnetic elements remain magnetized. Manipulating spin could also require far less power than steering charges does, says Ron Jansen of the University of Twente in Enschede, Netherlands. Some physicists even aspire to create a spooky quantum connection called "entanglement" between spin-polarized currents to make a quantum computer that could crack problems that stymie an ordinary one.

  • When first discovered in 2010, the Stuxnet computer worm posed a baffling puzzle. Beyond its unusually high level of sophistication loomed a more troubling mystery: its purpose. Ralph Langner and team helped crack the code that revealed this digital warhead's final target -- and its covert origins. In a fascinating look inside cyber-forensics, he explains how.

Ants Take a Cue From Facebook - ScienceNOW - 2 views

shared by pacome delva on 13 Apr 11 - No Cached
  • This pattern of interactions matches how humans share information on social networking sites like Facebook, says the study's lead author, biologist Noa Pinter-Wollman. Most Facebook users are connected to a relatively small number of friends. A handful of users, however, have thousands of friends and act as information hubs.
  • computer simulations of the ants' social networks showed that information flows fastest when a small number of individuals act as information hubs. Fast-flowing information allows ant colonies to respond faster to threats such as predators and weather hazards, Pinter-Wollman says.
  • These well-connected ants might have an advantage in responding to threats, but they are also more vulnerable to infectious diseases, which can spread quickly through the colony.

Speeding swarms of sensor robots - 2 views

  • the algorithm is designed for robots that will be monitoring an environment for long periods of time, tracing the same routes over and over. It assumes that the data of interest — temperature, the concentration of chemicals, the presence of organisms — fluctuate at different rates in different parts of the environment.
  • But it turns out to be a monstrously complex calculation. “It’s very hard to come up with a mathematical proof that you can really optimize the acquired knowledge,”
  • The new algorithm then determines a trajectory for the sensor that will maximize the amount of data it collects in high-priority regions, without neglecting lower-priority regions.
  • ...1 more annotation...
  • At the moment, the algorithm depends on either some antecedent estimate of rates of change for an environment or researchers’ prioritization of regions. But in principle, a robotic sensor should be able to deduce rates of change from its own measurements, and the MIT researchers are currently working to modify the algorithm so that it can revise its own computations in light of new evidence. “

    This could become quite relevant in future control systems if the setup can be made simple to keep alive and stable. I was doing some follow-up on a story about people controlling aircraft with their brainwaves (through EEG) when I ran into this really cool story. The idea of growing the neurons in patterns is incidentally very similar to the Physarium slime-mold stuff that Dario and me were curious about a little while ago.
  • Paul N on 02 Jun 14
     
    I think we already had a discussion on this during a wednesday meeting :P
  • johannessimon81 on 03 Jun 14
     
    Oh, I thought that was on the little robot that was controlled by rat neurons and bumped into EVERYTHING. The interesting thing here is that they add a surface patterning (with some kind of nutrient) to control the growth of cells. (Maybe that is not new either, though.)

    Amazing how some guys from some other university also did pretty much the same thing (although they didn't use the bidirectional stuff) and published it just last month. Just goes to show you can dump pretty much anything into an RNN and train it for long enough and it'll produce magic. http://arxiv.org/pdf/1410.1090v1.pdf

    Seems like quite the trend. And the fact that google still tries to use LSTMs is even more surprising.

    LSTMs: that was also the first thing in the paper that caught my attention! :) I hadn't seen them in the wild in years... My oversight most likely. The paper seems to be getting ~100 citations a year. Someone's using them.

    There are a few papers on them. Though you have to be lucky to get them to work. The backprop is horrendous.

    There is this optical neuron that gets stimulated from motion. Mapping it is difficult in the lab: "The stumbling block is a lack of fine-grained anatomical detail about how the neurons in the retina are wired up to each other." So, use people deciphering from 2D images --> the 3D neuron structure using the human spatial reasoning to figure out what is part of a branching cell and what is just background noise in the images (yet incomparable to their best algorithms' performance) 120.000 users so far mapped 2% of the retina

"What we believe is that there may be, in fact, some more fundamental reason why [quantum mechanics] looks the way it does."

    A common data hub that allows the representation and comparison of data from numerous space missions. "The IMPEx portal offers tools for the visualization and analysis of datasets from different space missions. Furthermore, several computational model databases are feeding into the environment." As they say, with its massive 3D-visualization capabilities it offers the possibility of displaying spacecraft trajectories, planetary ephemerides as well as scientific representations of observational and simulation datasets.

Einstein even called quantum effects "spooky."
