Improving sensitivity of oral fluid testing in IgG prevalence studies: application of mixture models to a rubella antibody survey [PDF]

, 2003
A method for the analysis of age-stratified antibody prevalence surveys is applied to a previously reported survey of antibody to rubella virus using oral fluid samples in which the sensitivity of the assay used was shown to be compromised.

Representation of Long‐Term Observed UK Winter Precipitation Trends and Variability in UKCP18 Global Climate Models

International Journal of Climatology, EarlyView.
Evaluating historical precipitation trends is complicated by interactions between variability in atmospheric circulation and thermodynamic forcing. This study assesses 1901–2023 UK winter precipitation trends in UK Climate Projections 2018 (UKCP18) global climate models using dynamical adjustment to separate circulation‐driven and non‐dynamical ...

Renal Trichodinosis in the Japanese Rice Fish, Oryzias latipes: First Report and Phylogenetic Classification

Journal of Fish Diseases, EarlyView.
ABSTRACT Investigation of a disease outbreak in a hobbyist's medaka (Oryzias latipes) collection led to the detection of Trichodina sp. in the kidney tubuli of individual fish. Based on this observation, a thorough clinical workup, including native microscopy, histopathology and molecular genetics, was conducted.

The Impact of an Integrated steM Camp on Middle School Students' Enjoyment, Career Knowledge, and Career Interest

School Science and Mathematics, EarlyView.
ABSTRACT Much of the work in STEM camps tends to be science‐driven with little attention given to mathematics. Guided by a mixed methods embedded research design using data from observations, questionnaires, and a group interview, we investigate if a camp that explicitly integrates mathematics had a positive impact on middle school students' STEM ...
