The ADIS must match this pair of x-rays. The teeth match, but the images are flipped [and different how else, if any?].

In its most significant challenge, the ADIS must be able to match x-ray pairs in which one image shows the same teeth at a different angle, as in this pair of matching x-rays.

By matching bicuspid to bicuspid and filling to filling, forensic investigators use dental records to give a John or Jane Doe a real name. Researchers from West Virginia University, Michigan State University and the University of Miami are combining advanced image-processing techniques with elements of logic to accelerate and improve the accuracy of identity matches.
The researchers are working on an Automated Dental Identification System (ADIS) that will compare a database of dental x-rays with x-rays of an unidentified victim. Currently, the FBI’s National Crime Information Center uses a text-based database with manually coded descriptions of an individual’s teeth and jaw.
Supported by a National Science Foundation Digital Government award, the team is led by West Virginia University computer science professor Hany Ammar and includes professors Robert Howell at West Virginia, Anil Jain at Michigan State and Mohamed Abdel-Mottaleb at Miami, as well as FBI collaborators in the Criminal Justice Information Services division.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
