We report on high spectral resolution observations of five damped Lyman-α absorbers: zabs = 3.0248 toward Q 0347–383, zabs = 2.1411 and 2.8112 toward Q 0528–250, zabs = 2.6184 toward Q 0913+072, and zabs = 2.5226 toward Q 1213+093. Line velocity profiles and heavy element abundances are discussed. Nitrogen is found to have abundances less than silicon in the systems toward Q 0347−383, Q 0913+07...

and model’s scores The RMSE improvement presented in the abstract corresponds to the RMSE on stations, given in Section 4. We agree that the model’s performance cannot be summarized by this mild improvement, and we should insist more on the better representation of the spatial variability. As the reviewer states, the results for NO in terms of total RMSE are “surprisingly low” when given in the...

Agricultural system models are tools to represent and understand major processes and their interactions in agricultural systems. We used the Root Zone Water Quality Model (RZWQM) with 26 years of data from a study near Nashua, IA to evaluate year to year crop yield, water, and N balances. The model was calibrated using data from one 0.4 ha plot and evaluated by comparing simulated values with d...

OBJECTIVES The 29-item Multiple Sclerosis Impact Scale (MSIS-29) is a psychometrically validated patient-reported outcome measure increasingly used in trials of treatments for multiple sclerosis. However, it is non-preference-based and not amenable for use across policy decision-making contexts. Our objective was to statistically map from the MSIS-29, version 2, to the EuroQol five-dimension (E...

With a planned launch no later than September 2018, the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) will provide a global distribution of geodetic elevation measurements for both the terrain surface and relative canopy heights. The Advanced Topographic Laser Altimeter System (ATLAS) instrument on-board ICESat-2 is a LiDAR system sensitive to the photon level. The photon-counting techno...

Received ; accepted – 2 – ABSTRACT We report the detection of velocity variations in the pulsating sdB star, PG 1605+072. Oscillations are detected at the same frequencies found from photom-etry and have amplitudes of up to 14 km s −1 for Hβ. The strongest oscillation found in previous photometric observations is not evident in our spectroscopy or photometry, and may be absent due to beating of...

We present time-series spectroscopy and multi-band photometry of the sdBV PG1605+072 carried out simultaneously at the Calar Alto 2.2m and 3.5m telescopes. The periodogram analysis of the radial velocity curves reveals three frequencies at 2.078, 2.756, and 1.985 mHz for Hβ and at 2.076, 2.753, and 1.978 mHz for Hγ . The corresponding radial velocity amplitudes are 12.7, 8.0, and 7.9 km/s for H...
