BackgroundNon-invasive brain stimulation techniques such as transcranial magnetic and direct current hold promise for inducing plasticity. However, their limited precision may hamper certain applications. In contrast, Transcranial Ultrasound Stimulation (TUS), known its deep targeting capabilities, requires further investigation to establish efficacy in producing enduring effects treating neurological psychiatric disorders.ObjectiveTo investigate the of different pulse repetition frequencies...
GPS signals are refracted by the dispersive ionosphere, resulting in ranging errors dependent on both given signal frequency and ionospheric total electron content. Such range translate into a degradation of positioning accuracies. While it is possible to mitigate impact effects applications through ionosphere modeling and/or differential techniques (DGPS), residual may persist regions where steep gradients or localized irregularities density exist, particularly during periods high...

Enhanced ionospheric effects may exist during space weather events, leading to degradations in GPS performance and positioning accuracies. This issue is a concern for reliable operation of safety-critical systems, such as marine DGPS services or Satellite-Based Augmentation Systems (SBAS) aviation applications. These storm-related tend peak the years following solar maximum, will continue be applications over next few (2002-2003). In order provide timely predictions we have recently...
