Full Characterisation of Heroin Samples Using Infrared Spectroscopy and Multivariate Calibration

the collected spectral data and PLS modelling. These models were able to identify heroin correctly for 96% of the samples of the external test set with precision, specificity and sensitivity values of ...

Attributing Ethiopian animal health losses to high-level causes using expert elicitation

high-level causes (infectious, non-infectious, and external). Separate in-person workshops were conducted with eight cattle, nine small ruminant, and eight chicken experts. Following the ...

Comparing frailty prevalence between countries: validation of the Global Burden of Disease study Frailty Index (GBD-FI) in the survey of health, ageing and retirement in Europe

generate frailty scores from items available in the Global Burden of Disease study. OBJECTIVE: To externally validate the GBD- FI. METHODS: Data were obtained from the Survey of Health Ageing and Retirement ...

Multidimensional chromatographic fingerprinting combined with chemometrics for the identification of regulated plants in suspicious plant food supplements

explored: (a) binary modelling and (b) multiclass modelling. The correct classification rate % (ccr%) for cross validation, modelling and external test prediction were used to select the optimal model for ...

SCORE2-Diabetes: 10-year cardiovascular risk estimation in type 2 diabetes in Europe.

regions. External validation included 217 036 further individuals (38 602 CVD events), and showed good discrimination, and improvement over SCORE2 (C-index change from 0.009 to 0.031). Regional calibration ...

COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS

square – discriminate analysis. A minimum of 86% correct classification rate for external test set validation (17 sample for binary dataset and 59 samples for multiclass dataset) was observed for all ...

Multidimensional Chromatographic Fingerprinting Combined with Chemometrics for the Identification of Regulated Plants in Suspicious Plant Food Supplements.

DA) through (a) binary modelling and (b) multiclass modelling. The correct classification rates (ccr%) by cross-validation, modelling, and external test set validation were satisfactory for both ...

Advances in the physicochemical characterization of nanoparticles in a regulatory context.

its resolution covering 1-100 nm, its possibility to identify constituent particles in aggregates and agglomerates and to measure key parameters such as their minimal external dimension on ...

Methodological considerations in injury burden of disease studies across Europe: a systematic literature review.

European countries. Approximately 79% of injury BoD studies reported the BoD by external cause-of-injury. Most independent studies used the incidence-based approach to calculate YLD s. About half of the ...

Use of near infrared spectroscopy and chemometrics for the classification of different Cannabis spp. samples found in Belgium

of 92 % (for the benchtop) and 93 % (for the handheld device),  meaning that 51 of the 56 samples and 52 of 56 samples in the external test set are correctly classified as recreational drug, industrial ...
