TL;DR: Rosemary extracts showed higher antioxidant activity, even more than the phenol compounds separately, and ethanol oregano extracts containing high concentrations of phenols, mainly rosmarinic acid, efficiently prevented colour deterioration.

TL;DR: The first Fermi-LAT catalog of >10GeV sources (1FHL) has 514 sources as discussed by the authors, of which 449 (87%) could be associated with known sources, of which 393 (76% of the 1FHL sources) are active galactic nuclei.
Abstract: We present a catalog of gamma-ray sources at energies above 10 GeV based on data from the Large Area Telescope (LAT) accumulated during the first three years of the Fermi Gamma-ray Space Telescope mission. The first Fermi-LAT catalog of >10GeV sources (1FHL) has 514 sources. For each source we present location, spectrum, a measure of variability, and associations with cataloged sources at other wavelengths. We found that 449 (87%) could be associated with known sources, of which 393 (76% of the 1FHL sources) are active galactic nuclei. Of the 27 sources associated with known pulsars, we find 20 (12) to have significant pulsations in the range >10GeV (>25GeV). In this work we also report that, at energies above 10 GeV, unresolved sources account for 27+/-8 % of the isotropic gamma-ray background, while the unresolved Galactic population contributes only at the few percent level to the Galactic diffuse background. We also highlight the subset of the 1FHL sources that are best candidates for detection at energies above 50-100 GeV with current and future ground-based gamma-ray observatories.

TL;DR: Density functional theory optimized basis sets for gradient corrected functionals for 3d transition metal atoms are presented and results are compared with available experimental data as well as with other theoretical data from the literature.
Abstract: Density functional theory optimized basis sets for gradient corrected functionals for 3d transition metal atoms are presented. Double zeta valence polarization and triple zeta valence polarization basis sets are optimized with the PW86 functional. The performance of the newly optimized basis sets is tested in atomic and molecular calculations. Excitation energies of 3d transition metal atoms, as well as electronic configurations, structural parameters, dissociation energies, and harmonic vibrational frequencies of a large number of molecules containing 3d transition metal elements, are presented. The obtained results are compared with available experimental data as well as with other theoretical data from the literature.

TL;DR: An efficient computational implementation of a path deletion K shortest paths algorithm and a new algorithm for the same problem that avoids the last K−1 executions of a shortest path algorithm are presented, resulting in a suprising and very substantial reduction in the execution time.

TL;DR: The algorithm is compared with other state-of-the-art SA algorithms and advanced global optimization methods and found better designs than the other SA-based algorithms and converged much more quickly to the optimum than HPSO and HS.
