RESEARCHER'S RISK EXPOSURE INDEX (REI) USED BY THE UN OFFICE FOR DISASTER RISK REDUCTION
"From Superstorms to Factory Fires: Managing Unpredictable Supply-Chain Disruptions," published recently in the Harvard Business Review, describes a method developed by MIT professor David Simchi-Levi, founder of the MIT Forum for Supply Chain Innovation, to manage unpredictable supply chain disruptions. This method helps prioritize the financial impact of risk through the Risk Exposure Index (REI), enabling companies to focus mitigation efforts on the most important suppliers and risk areas. The method was implemented successfully at Ford Motor Company.

NEW THEORY COULD REDUCE NUMBER OF SENSORS REQUIRED FOR TERAHERTZ IMAGING SYSTEMS
Terahertz imaging, which is already familiar from airport security checkpoints, has a number of other promising applications—from explosives detection to collision avoidance in cars. Like sonar or radar, terahertz imaging produces an image by comparing measurements across an array of sensors. Those arrays have to be very dense, since the distance between sensors is proportional to wavelength.

MATH STUDENT DETECTS OAUTH, OPENID SECURITY VULNERABILITY
(Phys.org) —To get right to the point, a doctoral candidate in math has discovered two holes in OAuth and OpenID that could leak data and redirect victims to unsafe sites. Friday's tech sites accordingly were buzzing with news of the discovery about a vulnerability in OAuth and OpenID protocols. Be cautious, said the reports, of links that ask you to log in through well known sites such as Facebook and Google. The OAuth 2.0 and OpenID login tools are "used by many websites and tech titans" including Google, Facebook, and Microsoft, among others," said Aloysius Low, writer at CNET Asia and Seth Rosenblatt, who covers Google and security for CNET News.

CARNEGIE MELLON GROUP SHOWS IPAD SKEUOMORPHISM
(Phys.org) —The Human Interfaces Group at Carnegie Mellon, led by the group's director Chris Harrison, an assistant professor of Human Computer Interaction, have done work that shows how traditional hand movements to perform tasks such as measuring and erasing can be naturally applied to the digital screen, improving on a natural interaction with computers. They have come up with TouchTools, a gesture design approach. With TouchTools, you manipulate tools on the screen just as you would in real life; the idea is to make software more natural to use. They are showing the world their TouchTools concept, which Gizmodo recently referred to as "skeuomorphism applied to interaction design."
