Replication data for: "Measuring vocabulary use in L2 English and L2 French writing: How methodological decisions shape the results"
No full textDataset for the statistical analyses in the paper: "Measuring vocabulary use in L2 English and L2 French writing: How methodological decisions shape the results". Data were collected from second language learners of English and French in secondary school (grade 10 and grade 12), who each completed a vocabulary test and writing tasks in both languages. The dataset contains participants' scores on the vocabulary tests and the values computed for several indices of vocabulary use in writing (lexical diversity and lexical sophistication). The indices were computed repeatedly for each participant, based on four operationalizations (two types of lemmatization and two types of word inclusion)
Howling Corrupted Music Speech (HCMS)
No full textThe database contains in total 28 music files and 30 speech files. The original speech files are taken from 8 original signals files including recorded male and female speech in four languages (Chinese, English, Dutch, and Russian) from an audiobook database [1]. while the original music files is taken from 7 pieces spanning various genres (e.g., jazz, opera) from 2 different music databases [2, 3]. Each file is a 20 s excerpt where the howling is simulated to start between the 8th and 9th second. This is simulated by feeding the music or speech source signal to a closed-loop system with a varying broadband gain. A total of 8 acoustic impulse responses (AIRs) were used for the simulations, hence covering a wide range of howling frequencies. The final dataset1 contains fewer excerpts than the number of excerpts originally generated, as it went through a pruning step conducted by three experts, aiming to eliminate unsuitable examples (exhibiting howling at multiple howling frequencies or no howling at all).

Replication Data for: Evolution of tolerance to chlorpyrifos causes cross-tolerance to another organophosphate and a carbamate, but reduces tolerance to a neonicotinoid and a pharmaceutical
No full textExposure to pesticides is a major stressor in freshwater ecosystems. While populations can evolve tolerance to pesticides and thereby ensure their persistence in contaminated environments, this may have important consequences for their sensitivity to other pollutants. Indeed, tolerance to one pollutant may both increase (as a cost of tolerance) or decrease (cross-tolerance) the sensitivity to other pollutants. Despite the increasing concern of pharmaceuticals in waterbodies, no patterns of pesticide-induced (cross-)tolerance have been studied. We conducted 48 h acute toxicity assays with a range of concentrations of different pollutants to determine how the evolution of tolerance to the insecticide chlorpyrifos affects the sensitivity to other pesticides and a pharmaceutical in the water flea Daphnia magna, a keystone zooplankton species in aquatic food webs. We capitalized on an experimental evolution trial with chlorpyrifos, hence could unambiguously identify any patterns in increased tolerance or sensitivity to the other pollutants as a direct result of the evolution of tolerance to chlorpyrifos. We found that evolution of tolerance to chlorpyrifos conferred cross-tolerance to another organophosphate, namely malathion (mean change in EC50,48h: factor 3.1), and to the carbamate carbaryl (factor 1.7), confirming that a shared mode of action favours the evolution of cross-tolerance. While the evolution of tolerance to chlorpyrifos did not affect the sensitivity to the pyrethroid esfenvalerate, it increased the sensitivity to the neonicotinoid imidacloprid as shown by the decrease in EC50,48h (factor 0.6). Notably, we demonstrated for the first time that the evolution of tolerance to a pesticide increased the sensitivity to a pharmaceutical, namely fluoxetine (decrease in EC50,48h with factor 0.7), thereby identifying an overlooked cost of tolerance to a pesticide. Given the increasing exposure to pesticides and pharmaceuticals, our results highlight that considering cross-tolerance and costs of tolerance is crucial in risk assessment of both pesticides and pharmaceuticals in aquatic ecosystems

Replication Data for: PRISM: Simple and Compact Identification and Signatures from Large Prime Degree Isogenies
No full textSageMath implementation of PRISM: PRime degree ISogeny Mechanism.
We give a proof of concept implementation of PRISM. In some cases, cleaner and more readable code is preferred over a fully optimized implementation.
The code, and in particular the ideal-to-isogeny translation algorithm, is based on the SQIsign2D-West SageMath implementation, which has been privately shared with us by the authors. This can be found in the folder sqisign2d_west. The code to compute (2,2)-isogenies using theta coordinates is based on ThetaIsogenies/two-isogenies. It can be found in theta_isogenies and theta_structures. The Kummer line code is based on FESTA-PKE/FESTA-SageMath. It can be found in montgomery_isogenies
Altered muscle transcriptome as molecular basis of long-term muscle weakness in survivors from critical illness
No full textData integrated in the manuscript “Altered muscle transcriptome as molecular basis of long-term muscle weakness in survivors from critical illness”.
Background: Critically ill patients requiring intensive care unit (ICU) admission suffer from muscle weakness that persists for years, compromising quality-of-life. The pathophysiology of this long-term weakness remains unclear. We hypothesized that former ICU-patients show a long-term abnormal RNA-expression profile, which may contribute to lower long-term strength and for which modifiable risk factors can be identified. Methods: This pre-planned secondary analysis of the EPaNIC-trial compared muscle transcriptomes of 115 former ICU-patients 5 years after critical illness and 30 matched controls with RNA-sequencing, followed by pathway over-representation and differential co-expression analyses of the differentially expressed RNAs. We used multivariable linear regression analyses to identify which of the abnormal RNA-expressions associated with the long-term muscle strength of the patients and to identify potential risk factors for the abnormal RNA-expressions. Results: In former patients, 234 down-regulated and 116 up-regulated RNAs were identified after adjustment for age, sex, and BMI. Pathway over-representation and further molecular and histological analyses indicated impaired mitochondrial energy metabolism, disturbed lipid metabolism, and increased collagen formation/fibrosis in former patients. Abnormal muscle RNA-expression in former patients correlated with lower long-term muscle strength. Several treatments given in-ICU and at 5-year follow-up associated with abnormal RNA-expression, most notably in-ICU early parenteral nutrition (early PN) and glucocorticoid use. Conclusion: Abnormal RNA-expression profiles 5 years after critical illness suggest disrupted mitochondrial function, disturbed lipid metabolism, and fibrosis, associated with lower long-term muscle strength and partly attributable to possibly avoidable risk factors. These findings open perspectives for prevention and possibly treatment of long-term muscle weakness after critical illness
