Penn State researchers have developed a computer program that mimics the results when a human appraises a task as threatening and feels worried before starting.
Dr. Frank Ritter, associate professor in the School of Information Sciences and Technology (IST), says, "In this study, we used our program to mimic the results achieved by people who can be seen as having a type of math anxiety. However, the program could also be used to study the effects of feeling threatened or worried before driving a car, using a computer or other stressful task -- and to help develop remedial strategies."
The results were described in a paper, "Using Cognitive Modeling To Study Behavior Moderators: Pre-Task Appraisal and Anxiety," presented this month at the 48th Annual Meeting of the Human Factors and Ergonomics Society in New Orleans. The authors are Ritter, Andrew Reifers, an IST doctoral student; Laura C. Klein, assistant professor of biobehavioral health, College of Health and Human Development; Karen Quigley, New Jersey Medical School, University of Medicine and Dentistry of New Jersey; and Mike Schoelles, Rensselaer Polytechnic Institute.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
