METHODS Patients with biopsy-proven colorectal adenocarcinoma who were operated between April 2005 and December 2008 were enrolled in this study. The GPS was estimated based on the measuremen...

Acquisition is the first step in the signal processing section of a Global Positioning System (GPS) receiver. It detects the presence of a GPS signal in the signals received by the antenna and provides estimates of code phase and Doppler to the tracking loops. The acquisition process depends upon the precorrelation bandwidth, analog-to-digital conversion (ADC), sampling frequency and predetecti...

Global positioning system (GPS) technology was made possible after the invention of the atomic clock. The first suggestion that GPS could be used to assess the physical activity of humans followed some 40 y later. There was a rapid uptake of GPS technology, with the literature concentrating on validation studies and the measurement of steady-state movement. The first attempts were made to valid...

BACKGROUND Current health policies assume that prescribing is more efficient and rational when general practitioners (GPs) work with a formulary or restricted drugs lists and thus with a limited range of drugs. Therefore we studied determinants of the range of drugs prescribed by general practitioners, distinguishing general GP-characteristics, characteristics of the practice setting, character...

METHODS Within the framework of the Quality and Costs of Primary Care in Europe (QUALICOPC) study, data were collected from a stratified sample of GPs using a standardized questionnaire between November 2011 and May 2012. Data analysis...
