A new sensor system being developed at the University of Missouri-Rolla may help get rescue personnel to the scene faster the next time a tornado or terrorist damages a bridge or other structure because of its ability to “memorize” the location of the damage.
Unlike all other infrastructure-embedded sensors, which reset following the disaster, the distributed cable sensors under development at UMR could “memorize” the most severe damage that occurred during a prior catastrophic event, allowing for an immediate assessment of the structure’s performance and integrity.
“This is critical to making a rapid decision for emergency responses and evaluations immediately following the catastrophic event,” says Dr. Genda Chen, associate professor of civil engineering at UMR. “The current practice requires sending an engineer inspector to every bridge along the emergency vehicle route to get into the striking area to rescue people. In the future, you could use a hand-held piece of equipment to detect whether there’s damage or not. We can detect the location and severity of damage areas within two inches.”

Researchers create new technique for manipulating polarization of terahertz radiation

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
