Since most criminals only strike when they aren’t being watched, reliable surveillance of homes and businesses is a round-the-clock job. A University of Rhode Island researcher has made that job considerably easier and less expensive, thanks to a new technology he developed that can automatically track moving objects in real time.
Using low-cost, commercially available hardware, the Automatic Image Motion Seeking (AIMS) camera follows a moving object and keeps the target at the center of the field of view.
"This camera has broad impact for security surveillance, because it eliminates the need to have a full-time guard watching a video screen," said Ying Sun, URI professor of electrical engineering who began developing the device in 2002. "It’s one intelligence level above any other existing system, and we’ve found the right compromise between speed and accuracy."

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
