OBJECTIVE It is uncertain whether migraine prevalence has increased in modern society. The aim of this study was to assess any change in migraine prevalence over an 8-year period among the adult population in Denmark. DESIGN Prospective longitudinal population-based study. SETTING 30 000 twin individuals were invited to participate in two cross-sectional questionnaire surveys containing val...

Terrestrial water storage (TWS) plays an important role in the global cycle. Measuring dynamic changes TWS is essential for resources management, weather-related hazard monitoring and agricultural production. The Gravity Recovery Climate Experiment (GRACE) its following mission (GRACE-Follow on) have provided monthly terrestrial anomalies (TWSA) at a quasi-global scale since April 2002. This st...

Solar power generation is being touted as a solution to our ever-increasing energy consumption and dependence on fossil fuels. Satellites in Earth’s orbit can capture solar energy through photovoltaic cells and transmit that power to ground based stations. Solar cells in orbit are not hindered by weather, clouds, or night. The energy generated by this process is clean and pollution-free. Althou...

The Florida State Twin Registry began in 2002 through a pilot study of personality disorders and executive cognitive functioning in adult twins. Since 2006, the registry has grown substantially as part of the Learning Disability Research Center at Florida State University that recently began its second funding cycle through the National Institute of Child Health and Development. An update on th...

In recent years, several SAR satellites such as TerraSAR-X, COSMO-SkyMed and Radarsat-2 have been launched. These satellites provide high resolution data suitable for sophisticated interferometric applications. With shorter repeat cycles, smaller orbital tubes and higher bandwidth of the satellites; deformation time series analysis of distributed scatterers (DSs) is now supported by a practical...

1. Aeronautical Communications Systems must be reliable and efficient. Connection to Aeronautical networks is considered to be achieved by satellites with large coverage areas especially over oceanic regions during long-haul flights. The service concept needs to take into account today's peculiarities of satellite communications, thus it must cope with the available or in near future available ...
