- This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete release of the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, which reached its goal of surveying over 10,000 nearby galaxies. The complete release of the MaNGA Stellar Library accompanies this data, providing observations of almost 30,000 stars through the MaNGA instrument during bright time. DR17 also contains the complete release of the Apache Point Observatory Galactic Evolution Experiment 2 survey that publicly releases infrared spectra of over 650,000 stars. The main sample from the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), as well as the subsurvey Time Domain Spectroscopic Survey data were fully released in DR16. New single-fiber optical spectroscopy released in DR17 is from the SPectroscipic IDentification of ERosita Survey subsurvey and the eBOSS-RM program. Along with the primary data sets, DR17 includes 25 new or updated value-added catalogs. This paper concludes the release of SDSS-IV survey data. SDSS continues into its fifth phase with observations already underway for the Milky Way Mapper, Local Volume Mapper, and Black Hole Mapper surveys.

Study of energy response and resolution of the ATLAS Tile Calorimeter to hadrons of energies from 16 to 30 GeV
- 2021
-
In: European Physical Journal C. - : Springer Science and Business Media LLC. - 1434-6044 .- 1434-6052. ; 81:6
-
Journal article (peer-reviewed)abstract
- Three spare modules of the ATLAS Tile Calorimeter were exposed to test beams from the Super Proton Synchrotron accelerator at CERN in 2017. The detector’s measurements of the energy response and resolution to positive pions and kaons, and protons with energies ranging from 16 to 30 GeV are reported. The results have uncertainties of a few percent. They were compared to the predictions of the Geant4-based simulation program used in ATLAS to estimate the response of the detector to proton-proton events at the Large Hadron Collider. The determinations obtained using experimental and simulated data agree within the uncertainties.

Soil moisture and hydrology projections of the permafrost region-a model intercomparison
- 2020
-
In: Cryosphere. - : Copernicus GmbH. - 1994-0416. ; 14:2, s. 445-459
-
Journal article (peer-reviewed)abstract
- This study investigates and compares soil moisture and hydrology projections of broadly used land models with permafrost processes and highlights the causes and impacts of permafrost zone soil moisture projections. Climate models project warmer temperatures and increases in precipitation (P) which will intensify evapotranspiration (ET) and runoff in land models. However, this study shows that most models project a long-term drying of the surface soil (0-20 cm) for the permafrost region despite increases in the net air-surface water flux (P-ET). Drying is generally explained by infiltration of moisture to deeper soil layers as the active layer deepens or permafrost thaws completely. Although most models agree on drying, the projections vary strongly in magnitude and spatial pattern. Land models tend to agree with decadal runoff trends but underestimate runoff volume when compared to gauge data across the major Arctic river basins, potentially indicating model structural limitations. Coordinated efforts to address the ongoing challenges presented in this study will help reduce uncertainty in our capability to predict the future Arctic hydrological state and associated land-atmosphere biogeochemical processes across spatial and temporal scales.

Impact of non-adherence to direct oral anticoagulants amongst Swedish patients with non-valvular atrial fibrillation: results from a real-world cost-utility analysis
- 2022
-
In: Journal of Medical Economics. - : Taylor & Francis. - 1369-6998 .- 1941-837X. ; 25:1, s. 1085-1091

Journal article (peer-reviewed)abstract
- Aims: A third of non-valvular atrial fibrillation (NVAF) patients are non-adherent to direct oral anticoagulants (DOACs). Estimates of the economic value of full adherence and the cost of two types of adherence improving interventions are important to healthcare planners and decision-makers.Methods: A cost-utility analysis estimated the impact of non-adherence over a 20-year horizon, for a patient cohort with a mean age of 77 years, based on data from the Stockholm Healthcare database of NVAF patients with incident stroke between 2011 and 2018. Adherence was defined using a medication possession ratio (MPR) cut-off of 90%; primary outcomes were the number of ischemic strokes and associated incremental cost–utility ratio.Results: Hypothetical comparisons between cohorts of 1,000 patients with varying non-adherence levels and full adherence (MPR >90%) predicted an additional number of strokes ranging from 117 (MPR = 81–90%) to 866 (MPR <60%), and years of life lost ranging from 177 (MPR = 81– 90%) to 1,318 (MPR < 60%; discounted at 3%). Chronic disease co-management intervention occurring during each DOAC prescription renewal and patient education intervention at DOAC initiation will be cost-saving to the health system if its cost is below SEK 143 and SEK 4,655, and cost-effective if below SEK 858 and SEK 28,665, respectively.Conclusion: Adherence improving interventions for NVAF patients on DOACs such as chronic disease co-management and patient education can be cost-saving and cost-effective, within a range of costs that appear reasonable to the Swedish healthcare system.
