SAN FRANCISCO wholesale air max 90 , April 30 (Xinhua) -- A game developed by the University of Washington (UW) Center for Game Science in partnership with the Allen Institute for Brain Science enables citizen scientists to produce complete, three-dimensional reconstructions of neurons from different regions of the brain in animals and people.


With the game, known as Mozak, which was launched in November, novice players numbering roughly 200 a day and Allen Institute neuroscientists have been able to reconstruct neurons 3.6 times faster than previous methods.


The players have outperformed computers at tracing the complicated shapes of neurons. They can produce reconstructions that are 70 to 90 percent complete, compared to roughly 10 to 20 percent for the most effective computer-generated reconstructions.


Mozak shows players a magnified volumetric image of a neuron wholesale air max 270 , which a key type of brain cell that transmits information throughout the nervous system, and asks the viewer to trace or draw its visible branches, which can also appear as disconnected dots in more challenging areas of data.


Many neurons have delicate and highly branched structures that human eyes can distinguish far better than computers alone. People also tend to be much better at inferring the likely detailed structure from faint and sometimes discontinuous data. Yet computers are better at performing tedious tasks that can take humans a long time and are faster at reconstructing from clear and continuous data. Mozak brings together people and computing in a new way, to solve this enormous problem together.


"This is not a story about people beating computers because people are using subsets of these computational tools," said Center for Game Science director Zoran Popovic, a professor at the Paul G. Allen School of Computer Science & Engineering. "This is about leveraging the things that computers can do well and the things that people do really well when they're trained wholesale new air max , forming a symbiotic superpower capable of solving unsolved challenges in science."


The creation of Mozak was inspired partly by the growing needs for analyzing data generated by global projects like the BRAIN initiative, said neuroscientist Jane Roskams, who served on the BRAIN advisory working group.


Until recently, neuroscience labs were doing well to trace about one neuron a week, said Stephen Smith, senior investigator for the Allen Institute for Brain Science. Mozak can speed that progress wholesale air max 2019 , but fully understanding neural networks will require tracing many thousands of neurons.

OSLO, July 13 (Xinhua) -- Norwegian Directorate of Immigration (UDI) has undergone training in checking foreigners on social media websites and will use this knowledge to detect if asylum seekers are cheating, newspaper Aftenposten reported Thursday.


Norwegian immigration and police authorities use Facebook in order to reveal holes in asylum seekers' stories and check their identities, and in these cases social media play a key role, the report said.


UDI's executive officers have got their own guidelines for using social media and will use them in their work, the report said.


Hanne Merete Jendal wholesale air max 2018 , director of UDI's asylum department, told Aftenposten they investigated information available on Facebook, Twitter, and Instagram, but assured "we stay within that which is the legitimate use of such sources."


"Information that we find in open sources can therefore also give us an indication of other investigations we should take. These may include investigations related to family relationships, birthplace wholesale air max froma china , residence, nationality and education," she said.


According to Jendal, these findings can also reveal whether asylum seekers have been honest about their stay in Norway and whether they have been travelling back to the countries they fled.


After the sudden immigration stop at the end of 2015, UDI has worked on checking the old cases, after which several foreigners lost their Norwegian citizenship and residence permit.


Social media have been an important source in these situations wholesale air max free shipping , UDI added.


"We have examples when people have stated to be from Somalia, but where searches in social media give grounds for believing they are from Djibouti or Ethiopia," Jendal said.


False identity and background has also been discovered among stateless Palestinians who actually come from Jordan, as well as among Syrians who, before the civil war in Syria, sought asylum as Iraqis.


However wholesale air max black friday , Jensen emphasized that in all cases, foreigners have an opportunity to comment and give alternative explanations of UDI's social media findings before it makes a decision on revocation.


"The finding can be an indication that leads to further investigations, and these findings must always be weighted against other moments and other information," she added.


"During the asylum wave in 2015, we really saw the value in electronic communication. In the past, we did not really trust those kind of tracks. However wholesale air max shoes , during the chaos in 2015 ,it became clear to us that we had to make efforts to immediately find out more about asylum seekers," Jan Olav Frantsvold, head of the legal department at the Norwegian Police Immigration Services (PU), told Aftenposten.


Frantsvold added, however wholesale air max , that this was still a little explored field for the PU, although there were clear limits to what information poli.
