IRT‐based response style models and related methodology: Review and commentary
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract We provide a review and commentary on recent methodological research related to item response theory (IRT) modelling of response styles in psychological measurement. Our review describes the different categories of IRT models that have been proposed, their associated assumptions and extensions, and the varying purposes they can serve.

Brain Pathology, EarlyView.The efficacy of the novel anti‐tau active immunotherapy, p5555kb, was tested using two mouse models of tau pathology. p5555kb inoculation increased the survival rate and reduced tau pathology in tau‐overexpressing P301L mice and decreased tau seeding in the brains of C57BL/6 mice injected with human‐purified Alzheimer's disease tau.

Dynamical Gaussian, lognormal, and reverse lognormal maximum‐likelihood ensemble filter
Quarterly Journal of the Royal Meteorological SocietyAbstractWe present a non‐Gaussian ensemble data assimilation method based on the maximum‐likelihood ensemble filter, which allows for any combination of Gaussian, lognormal, and reverse lognormal errors in both the background and the observations.
