Using five million responses to thousands of practice examination questions on an optional study service known as Problem Roulette, we explore subject-specific differences in assessment style, grade benefit from usage of the service, and differential features in study behavior and grade outcome by birth sex. Our study includes more than 20,000 students enrolled in eight terms of introductory courses in general chemistry, physics and statistics. Student responses in the space of accuracy and response time reveal domain differences;by these measures, physics problems are typically both more difficult and more complex. Grouping students by term-length practice volume, we find significant positive grade benefits to higher volumes of study in chemistry and statistics. Across all subjects, we find that females gain more grade benefit from high study volume than males. Female students also outwork males during prime study hours yet, on average, earn 0:13 +/- 0:03 lower grade points in chemistry than males with the same response accuracy in practice, with null results in statistics and physics.

Energy management and energy efficiency for small electricity customers as part of a Smart Grid strategy are gaining significance with increasing share of renewable and distributed generation. The concept presented provides a single Gateway between the customer and the grid on top of which a variety of applications shall be executable, which access costumer devices, user displays, smart meters, measuring data, pricing data etc.

The introduction of smart meter solutions especially within the residential and commercial customer segment-will lead to new opportunities for customer interaction with the energy market and for boosting consumer awareness for electricity consumption. Both of them help to increase end user energy efficiency. Within the BMWi project E-Energy the E-DeMa consortium with the members RWE, Siemens, ***, Stadtwerke Krefeld, Miele and ProSyst draws on the capabilities of current smart meter solutions and extends them to a future marketplace for all services and products around demand side management, flexible tariff structures or network services. The subscriber as prosumer (simultaneously producer and consumer) develops to become an active market player. The aim of this project is to create conditions for the efficient hand-ling of energy resources.

The National Bernstein Network Computational Neuroscience is a funding initiative of the German Federal Ministry of Education and Research (BMBF). It aims at understanding the brain's function through the interdisciplinary approach of Computational Neuroscience. In a joint collaborative effort, biologists, physicians, psychologists, physicists, mathematicians, and computer scientists translate experimental results into mathematical models that can be tested in computer simulations. Their insights into normal and pathologically altered brain functions open new perspectives for innovative treatments as well as technological applications.
