Although recovery from spinal cord injury is generally meager, evidence suggests that step training can improve stepping performance, particularly after neonatal spinal injury. The location and nature of the changes in neural substrates underlying the behavioral improvements are not well understood. We examined the kinematics of stepping performance and cellular and synaptic electrophysiologica...

The large (V/m) mesospheric electric fields have been identified as a possible cause of VLF phase perturbations. These fields affect the fundamental processes that govern the lower D region parameters, primarily the electron temperature and effective collision frequency. The main ionospheric parameter needed to calculate VLF phase perturbations is the low-frequency electron plasma conductivity....

[1] An array of seven ELF/VLF receivers in Alaska is utilized for direction finding and determination of ionospheric exit point of whistler mode chorus waves from the Earth’s magnetosphere. Each receiver records both orthogonal horizontal magnetic components of the chorus waves. All sites use GPS-synchronized sampling, allowing for the localization of ionospheric exit points utilizing both arri...

Mathematical modeling and analysis of a DRT-VLF high voltage test generator. Due to the forced construction of regenerative decentralized power generation systems, high and ultra high voltage cables are frequently used, such that the demand on an efficient possibility for the on-site testing of the quality of the cables has increased in recent years. Therefore, test generators with very low fre...

[1] The MF data recorded by the low-altitude satellite DEMETER have been used to survey the MF waves around the Earth. A global map of the MF emissions indicates that there exists a wave activity in the frequency range 2–2.5 MHz above the main powerful VLF ground-based transmitters operating in the frequency range 18–50 kHz. It is shown that this is due to the high-frequency part of whistlers i...
