We quantitatively predict the observed continuum-like spectral broadening in a 90-mm weakly birefringent all-normal dispersion-flattened photonic crystal fiber pumped by 1041-nm 229-fs 76-MHz pulses from a solid-state Yb:KYW laser. The well-characterized continuum pulses span a bandwidth of up to 300 nm around the laser wavelength, allowing high spectral(More)
BACKGROUND The objective of this study was to analyse the association between area deprivation at municipality level and the prevalence of type 2 diabetes (T2D) and obesity across Germany, controlling for individual socioeconomic status (SES). METHODS The analyses are based on a large survey conducted in 2006. Information was included from 39,908 adults(More)
Although monitoring smoking behavior is considered as most important to tackle the smoking epidemic, empirical evidence concerning age-specific variations of its income-related inequalities still seems scarce. This paper uses a semiparametric extension of the concentration index to measure age-specific variations of income-related inequalities in smoking(More)
