Application of Static Headspace GC-MS Method for Selective 1,4-Dioxane Detection in Food Additives
Foods, 2023 Efficient detection methods must be developed for 1,4-dioxane due to its suspected status as a human carcinogen, which is highly mobile in food and environmental resources.

Determination of the limit of quantification of the calorimeter using a mixture of benzoic acid and silicon dioxide [PDF]
Hemijska Industrija, 2011 In recent years quality control has received a great attention in laboratory work. Implementation of the international standard ISO/IEC 17025 is necessary for any laboratory that wishes to establish quality control in its work.

Limitations and challenges of genetic barcode quantification [PDF]
Scientific Reports, 2017 AbstractGenetic barcodes are increasingly used to track individual cells and to quantitatively assess their clonal contributions over time. Although barcode quantification relies entirely on counting sequencing reads, detailed studies about the method’s accuracy are still limited.

Ensemble-SINDy: Robust sparse model discovery in the low-data, high-noise limit, with active learning and control [PDF]
Proceedings of the Royal Society A, 2021 Sparse model identification enables the discovery of nonlinear dynamical systems purely from data; however, this approach is sensitive to noise, especially in the low-data limit. In this work, we leverage the statistical approach of bootstrap aggregating

Limits of Fat Quantification in the Presence of Iron Overload [PDF]
Journal of Magnetic Resonance Imaging, 2021 BackgroundChemical shift encoded magnetic resonance imaging (CSE‐MRI)‐based tissue fat quantification is confounded by increased R2* signal decay rate caused by the presence of excess iron deposition.PurposeTo determine the upper limit of R2* above which it is no longer feasible to quantify proton density fat fraction (PDFF) reliably, using CSE‐MRI ...
