background: in this article, we used a panel smooth transition regression model to estimate the relationship between health expenditure and income. this approach is employed to continuously model changing parameters among countries and during time. it is thus suitable for eliminating heterogeneity among countries and the variability of the relationship between gross domestic product (gdp) and h...

[1] We use the GEOS-Chem chemical transport model to interpret observations of tropospheric ozone from the Tropospheric Emission Spectrometer (TES) satellite instrument in summer 2005. Observations from TES reveal elevated ozone in the middle troposphere (500–400 hPa) across North Africa and the Middle East. Observed ozone abundances in the middle troposphere are at a maximum in summer and a mi...
