Biber et al.'s (2016) set of 150 BNC items for the analysis of dispersion measures: Dataset for "Evaluation of text-level measures of lexical dispersion"
No full textThis dataset contains frequencies for a set of 150 word forms in the BNC. The set of items was compiled by Biber et al. (2016) for the purpose of analyzing the behavior of dispersion measures in different distributional settings. It was therefore assembled to cover a broad range of frequency and dispersion levels. For each form, the dataset lists (i) the number occurrences in each of the 4049 text files in the BNC, including zero counts; and (ii) the length of each text file, i.e. the number of word tokens it contains
Replication Data for: Harvesting history affects soil respiration and litterfall but not overall carbon balance in boreal Norway spruce forests
No full textThis dataset contains data on aboveground litter fluxes, soil respiration, basal area and microclimate of 24 forests stands in South-Eastern Norway. The stands were paired across forest management history, so that each of the 12 pairs consists of one previously clear-cut forest (aged 43–82) and one near-natural forest i.e. never clear-cut (mean age of dominating trees 96–189). We studied how forest management history affects carbon fluxes, and which factors drive soil respiration in these 24 stands. This study is part of the EcoForest project: https://ecoforest.no
Stand-out: A systematic review of the role of salience in second language acquisition
No full textDataset description:
This dataset contains the query results, and subsequent annotations, of a systematic review of empirical research on the role of salience in second language acquisition. Files includes a list of articles comprising the search results of our queries and their annotations after removing duplicates, a reference list of the included articles, and three sets of annotations of the included articles: one where rows are delineated by each salience manifestation variable, one where the rows are further expanded according to methodology used (to account for when multiple methodologies were employed in a single study), and one where the rows are further expanded according to additional variables considered alongside each manifestation variable (to account for when multiple additional variables were considered alongside a given manifestation variable).Article abstract:
Salience is frequently cited as a post-hoc explanation of results in second language acquisition (SLA) research. However, how salience is operationalized varies considerably and empirical investigations into the causal effect of salience are sparse. This systematic review analyzes studies that manipulated theorized salience manifestations in second-language contexts toward three primary objectives: (1) to provide an overview of how salience has been empirically operationalized in SLA research, (2) to synthesize existing findings on the impact of salience on second-language learning, and (3) to identify gaps in the current literature to guide future research toward a more comprehensive understanding of salience and its role in second-language acquisition. We extracted 473 references from the Web of Science and Scopus databases, retaining 42 studies for detailed analysis. Results indicate a positive relationship between higher levels of salience and second-language learning outcomes. Findings also show remaining gaps regarding isolated salience manifestations in general and psycholinguistic manifestations in particular.</p
Supporting data for: Accelerated Sarcopenia Phenotype in the DJ-1/Park7-Knockout Zebrafish
No full textThis dataset represent muscle samples from 4 and 12 month- old wild type and DJ-1/PARK7 knockout zebrafish labeled with TMT16-plex.Eclipse Orbitrap instrument was used and the data analysed with Proteome Discoverer Version 2.5.Abstract:Age-dependent loss of muscle mass and function is associated with oxidative stress. DJ-1/Park7 acts as an antioxidant through multiple signalling pathways. DJ-1-knockout zebrafish show a decline in swimming performance and loss of weight gain between 6 and 9 months of age. Here, we address the degree to which this is associated with muscle degeneration and identify molecular changes preceding dysregulation of muscle performance. Loss of DJ-1 reduced the skeletal muscle fibre cross-section area. The highly mitochondrial-dependent red slow muscle was more affected than the white muscle, and degeneration of sub-sarcolemma red muscle mitochondria was observed. Using TandemMassTag-based quantitative proteomics, we identified a total of 3721 proteins in the multiplex sample of 4 and 12-month-old muscles. A total of 68 proteins, mainly associated with inflammation and mitochondrial function, were dysregulated in the young DJ-1-null adults, with Annexin A3, Sphingomyelin phosphodiesterase acid-like 3B, Complement C3a, and 2,4-dienoyl CoA reductase 1 being the most affected. The loss of DJ-1 also accelerated molecular features associated with sarcopenia, such as a decrease in the NAD+/NADH ratio and a reduction in Prostaglandin reductase 2 and Cytosolic glycerol-3-phosphate dehydrogenase levels. In view of the experimental power of zebrafish, the DJ-1-null zebrafish makes a valuable model for understanding the connection between oxidative stress and age-dependent muscle loss and function
Replication Data for: "Vortex structures under dimples and scars in turbulent free-surface flows" (PART 3/4)
No full textThis data archive (along with parts 1, 2 and 4) contains simulation data for direct numerical simulations of isotropic turbulence interacting with a free surface, for different Reynolds numbers and Weber numbers.
The data is generated by computing time evolution of the incompressible Navier-Stokes equations and continuity equation on a three-dimensional domain, which is periodic in horizontal directions, restricted from above by a deformable free surface (resolved by the kinematic and dynamic boundary conditions on a surface-adhering grid) and below by a free-slip boundary. Turbulence is generated by linear forcing in the centre of the domain.
For more detail on the simulations, parameters and flow problem, see the research article "Vortex structures under dimples and scars in turbulent free-surface flows", by Aarnes, JR, Babiker, O, Xuan, A, Shen, Lian, and Ellingsen, SA, in the Journal of Fluid Mechanics (2025).
The data archive is split over four different repositories (case details in Aarnes et al., 2025).):
Part 1: Data for case 1, Re = 2500, We = infinity. (doi.org/10.18710/XQ81WH)
Part 2: Data for case 2, Re = 2500, We = 20. (doi.org/10.18710/MBK9JF)
Part 3: Data for case 3, Re = 2500, We = 10. (doi.org/10.18710/PN7DZA)
Part 4: Data for cases 4-6, Re = 1000, We = infinity, 20, 10. (doi.org/10.18710/UAT043)
Each archive also contains the same readme file with instruction on how to get started and a data loader script which can read the binary files which the .tar-files contain. Due to storage limitations, only data for the upper part of the flow is included in this data archive. The thickness of the upper part is two times the viscous boundary layer. Moreover, the data is limited to approximately half of each time series, also to limit the storage requirement

Background data for: Soil characteristics at artificial salt licks and their potential impacts on occurrence of chronic wasting disease
No full textBackground Data for Soil characteristics at artificial salt licks and their potential impacts on occurrence of chronic wasting diseaseAbstract
Salt lick sites, where artificial salt blocks are placed at permanent locations, are common in summer grazing areas for free ranging sheep in Norwegian mountains. These areas often overlap with areas used by wild reindeer and reindeer are frequently observed at these salt lick sites. The first cases of chronic wasting disease (CWD) were discovered among Norwegian wild reindeer in 2016, and salt lick sites were presumed to be hotspots for transmission of CWD. In this study we compare soil properties at salt lick and nearby control sites not affected by salt blocks, and review how salt-induced changes may influence persistence and transmission of CWD. Three wild reindeer areas were studied: one CWD-affected area, Nordfjella, and two areas without CWD, Knutshø and Forollhogna. The soils at the salt lick sites were strongly influenced by dissolving salt blocks and increased animal activity. The salt lick sites had higher pH and ionic strength and increased levels of sodium (Na), chlorine (Cl), calcium (Ca), magnesium (Mg), zinc (Zn), manganese (Mn) and iodine (I), reflecting the composition of the salt blocks. The increased animal activity was reflected in eroded topsoil causing less soil organic matter (SOM), and there were higher amounts of elements related to defecation and urination, giving higher concentrations of inorganic nitrogen (Inorg-N), phosphate (PO4-P), sulphate (SO4-S), potassium (K) as well as high gastrointestinal parasite frequency and diversity. The high salt content in the salt lick soils may stimulate geophagy and as the soil is heavily contaminated by animal excretions, this may facilitate prion transmission. In addition, the high pH and ionic strength in the salt licks soils increases both the cation attraction and anion diffusion towards the soil particles thereby facilitating both persistence and transmission of CWD. There was an increase in salinity at the salt lick sites in a gradient from west to east most likely related to the coinciding decrease in precipitation. This suggest that if the use of permanent salt lick sites is discontinued the salt lick sites in the east will maintain their attraction for congregating animals and geophagy longer than the western sites
