Materials and Methods: We designed a novel unit harmonization system combining BM25, sentence embeddings, Bayesian optimization, and a bidirectional transformer based binary classifier for retrieving and matching laboratory test entries. The system was evaluated using the Optum Clinformatics Datamart dataset (7.5…

We consider the problem of identifying the units of measurement in a data column that contains both numeric values and unit symbols in each row, e.g., "5.2 l", "7 pints". In this case we seek to identify the dimension of the column (e.g. volume) and relate the unit symbols to valid units (e.g. litre, pint) obtained…

In this paper, we present such a comprehensive quantity extraction framework from text data. It efficiently detects combinations of values and units, the behavior of a quantity (e.g., rising or falling), and the concept a quantity is associated with. Our framework makes use of dependency parsing and a dictionary of…

Large-scale data obtained from aggregation of already collected multi-site neuroimaging datasets has been brought benefits such as higher statistical power, reliability, and robustness to the studies. Despite these promises from growth in sample size, substantial technical variability stemming from differences in…

Toxicological omics studies require comprehensive metadata to support reproducibility, inter-operability, and regulatory reuse. However, metadata requirements differ across public repositories, reporting frameworks, and laboratory workflows, resulting in inconsistent annotation and limited data integration. To address…

'Barry M. Lester' ''] Abstract The United States (U.S.) National Institutes of Health-funded Environmental influences on Child Health Outcomes (ECHO)-wide Cohort was established to conduct high impact, transdisciplinary science to improve child health and development. The cohort is a collaborative research design in…

First, we identified and collated the survey questions and response options by domain ([sup1] and [sup1], available as [sup1] at IJE online). We determined all skip patterns in the questions and respondent universe for each relevant question. For some questions, only a subset of respondents was included, such as a…

Background Valuation is a critical part of the costing process in health economic evaluations. However, an overview of specific issues relevant to the European context on harmonizing methodological requirements for the valuation of costs to be used in health economic evaluation is lacking. We aimed to inform the…

Artificial intelligence (AI) is revolutionizing scientific research across various disciplines. The foundation of scientific research lies in rigorous scientific computing based on standardized physical units. However, current mainstream high-performance numerical computing libraries for AI generally lack native…

Data harmonization is an important method for combining or transforming data. To date however, articles about data harmonization are field-specific and highly technical, making it difficult for researchers to derive general principles for how to engage in and contextualize data harmonization efforts. This commentary…

'Florian Müller' 'Christoph Schwingshackl' 'Maren Scheel' 'Sebastian Tatzko' 'Malte Krack'] Sinusoidal excitation is particularly popular for testing structures in the nonlinear regime. Due to the nonlinear behavior and the inevitable feedback of the structure on the exciter, higher harmonics in the applied excitation…

Biomedical research faces significant challenges in harmonizing metadata across diverse datasets due to inconsistent labeling and the lack of universally adopted ontologies. Conventional solutions, such as Common Data Elements, face adoption difficulties as they impede scientific progress by requiring researchers to…

Surface-pressure–area-per-molecule (π–A) isotherms provide useful mechanical, molecular, and affinity information about surfactant monolayers, especially lipid monolayers at air–water interface. However, significant discrepancies are seen between the reported experimental π–A curves even for the same lipid composition.…

The SI brochure’s treatment of quantities that it regards as dimensionless, with the associated unit one, requires certain physical quantities to be regarded as simply numbers. The resulting formal system erases the nature of these quantities and excludes them from important benefits that quantity calculus provides…
