Researchers: Computer-Based Deep Learning Is Essential for Physics Exploration

Deep learning can improve physicists’ ability to explore and discover subatomic particles, according to a new paper by the University of California, Irvine (UCI), scientists. They say computer-driven deep learning can help solve fundamental physics questions. Finding elusive particles such as the Higgs boson requires sifting through massive datasets from particle accelerators and other sources. Machine learning techniques—in which systems learn from information they process, rather than just follow explicitly programmed instructions—can keep scientists from having to write large amounts of code to analyze their data. The UCI researchers built a machine-learning system that increased particle detection by 8 percent over previous approaches. They published their findings in the journal Nature Communications.

Smartphone Application Secures DNA Data

A smartphone application developed at the University of California, Irvine, lets users securely store their DNA data on a mobile device and access it when necessary. GenoDroid is an Android application that encrypts the information so that only small portions of the user’s genetic data are available at a given time. Only the test results are disclosed, which means the user’s personal genetic information remains secure and private. The application could be used for genetic testing and custom drugs as well as secure paternity tests. The UC Irvine researchers worked with Palo Alto Research Center and New York Institute of Technology scientists. They published their results in the Association for Computing Machinery’s Proceedings of the 2012 ACM Workshop on Privacy in the Electronic Society.

Researchers Use 3D Printing to Help Small Manufacturers

3D printing technology has greatly reduced the time and cost associated with creating prototype parts. However, the cost has still been prohibitive for many small businesses because 3D printers typically cost between $50,000 and $1 million. The University of California, Irvine’s RapidTech is helping small businesses by providing affordable printing services for only the cost of the materials used. The system—which creates objects by adding layers of material based on the way it is programmed—has helped Airflow Systems—which makes aircraft cooling systems—, manufacture new parts, including those for vintage airplanes for which parts are not easy to find. For example, Airflow used the system to recreate parts needed by a museum to restore a 1938 Japanese Zero fighter plane based on incomplete and corroded original parts. The UC Irvine researchers say they work with businesses based on criteria including the project’s intellectual merit, as well as the project’s potential to train students and help other business enterprises.
