Recent experiments seem to confirm predictions that interactions lead to charge density wave ground states in higher Landau levels. These new ``correlated'' ground states of the quantum Hall system manifest themselves for example in a strongly ...

Optimization of constant power control of wind turbines to provide power reserves [PDF]
In several countries, the wind power penetration increased tremendously in the last years. As the current wind turbines do not participate in frequency control nor reserve provision, this may compromise the proper functioning of the primary control and ...

Current Principles of Motor Control, with Special Reference to Vertebrate Locomotion.
The vertebrate control of locomotion involves all levels of the nervous system from cortex to the spinal cord. Here, we aim at covering all main aspects of this complex behavior - from the operation of the microcircuits in the spinal cord to the systems ...

Validation of suitable internal control genes for expression studies in aging. [PDF]
Quantitative data from experiments of gene expression are often normalized through levels of housekeeping genes transcription by assuming that expression of these genes is highly uniform. This practice is being questioned as it becomes increasingly clear

Maintenance of Millimeter-level Geodetic Reference Framework
The high-precision terrestrial reference frame, as the spatial benchmark for geodesy, is an important national infrastructure. However, due to the influence of nonlinear factors related to geophysical phenomena, the overall maintenance accuracy of the ITRF framework is still at the centimeter level.
