The study titled "Modeling the effect of driving experience on lane keeping performance using ACT-R cognitive architecture," authored by Shi Cao, Yulin Qin, and Mowei Shen, has been published on CHINESE SCIENCE BULLETIN, 2013.
Driving experience is a critical human factor of driving safety. In China, there are currently more than 100 million licensed drivers, about one-third of whom are novice drivers with driving experience no more than 3 years. The lack of driving experience is a potential risk factor of accidents.
From the perspective of cognitive psychology, driving is a complex task that requires seamless coordination of multiple cognitive skills including perception, decision, and memory. Analyzing the differences between novice and experienced drivers and studying the mechanisms of driving skill learning are very important and valuable for improving driver training courses and the innovation of training techniques.
Previous studies on driving skills often focused on one cognitive skill but lacked an integrated view of all necessary skills. Considering different aspects of driving skills, Cao et al. used driving simulation to directly measure driving performance (Figure 1), compared the difference between novice and experienced drivers, and quantitatively modeled the difference using computational simulation of human performance.
As the first author Shi Cao said, there were two major challenges of this study: (1) building computerized models that can simulate what happens in a driver's mind in terms of cognitive information processing and (2) figuring out which cognitive factors are different between novice and experienced drivers. Cognitive sciences have provided theories about the architecture of human mind, that is, the mind is a complex integration of different functional modules such as visual encoding, memory, and decision modules. Cognitive-architecture-based models integrate all aspects of cognition to explain how the mind works. Researchers are using such models to support the design and evaluation of complex human-machine systems.
The results from this study showed that the experienced drivers had better control of vehicle lane position than the novice drivers, which was simulated by setting a closer visual attention point for the novice drivers in the cognitive models. It indicates that novice drivers' poorer control of lane position may be due to not utilizing road information farther enough.
The authors believe that there will be more and more simulation and intelligent systems that can be used to facilitate driver training and improve driving safety. The driving simulator used in this study can also run on common personal computers that most people have today. After some configuration of road and environment scenarios, such simulators can be used to train new drivers under simulated emergencies such as tire explosion and skid. Computational models will be able to track the development of skills and intelligently determine the contents and progress of training. The authors are planning to develop such training systems in the next phase of research.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
