| Computer program assesses quality of Wikipedia entries Posted: 06 Aug 2014 11:22 AM PDT Wikipedia the free, online collaborative encyclopedia is an important source of information. However, while the team of volunteer editors endeavors to maintain high standards, there are occasionally problems with the veracity of content, deliberate vandalism and incomplete entries. Computer scientists have now devised a software algorithm that can automatically check a particular entry and rank it according to quality. |
| Ion duet offers tunable module for quantum simulator Posted: 06 Aug 2014 10:45 AM PDT Physicists have demonstrated a pas de deux of atomic ions that combines the fine choreography of dance with precise individual control. The ion duet is a component for a flexible quantum simulator that could be scaled up in size and configured to model quantum systems of a complexity that overwhelms traditional computer simulations. |
| Sensors that improve rail transport safety Posted: 06 Aug 2014 06:48 AM PDT A new kind of human-machine communication is to make it possible to detect damage to rail vehicles before it's too late. The technology also leads to an improvement in the servicing of trains, providing it only when needed. The technology relies on a cloud-supported, wireless network of sensors. |
| New prosthetic arm controlled by neural messages Posted: 06 Aug 2014 06:47 AM PDT A new prosthetic system aims to identify the memory of movement in the amputee's brain in order to manipulate the device. Controlling a prosthetic arm by just imagining a motion may now be possible. |
| Physicists eye neural fly data, find formula for Zipf's law Posted: 05 Aug 2014 01:33 PM PDT Physicists have identified a mechanism that may help explain Zipf's law -- a unique pattern of behavior found in disparate systems, including complex biological ones. The mathematical models demonstrate how Zipf's law naturally arises when a sufficient number of units react to a hidden variable in a system. |
