A Bayesian perspective on Biogen's aducanumab trial
Alzheimer's &Dementia, Volume 18, Issue 11, Page 2341-2351, November 2022., 2022 Abstract This perspective is a companion to a recent editorial on the use of Bayesian analysis in clinical research. We aim to introduce and highlight the relevance and advantages that Bayesian inference offers to clinical trials using the data on the amyloid antibody aducanumab presented at a Food and Drug Administration hearing in November 2020 as an

British Journal of Educational Technology, Volume 52, Issue 5, Page 1898-1916, September 2021., 2021 Abstract Recent years have seen a surge of calls for personalization of education. Automatised adaptivity in serious games has been advocated as a potential instantiation of such calls. Yet little is known about the extent to which personalised learning through automatised adaptivity poses an advantage for language learning over generalised teacher‐led

The use of Minimal Spanning Tree to characterize the 2D cluster galaxy distribution [PDF]
, 1998 We use the Minimal Spanning Tree to characterize the aggregation level of given sets of points. We test 3 distances based on the histogram of the MST edges to discriminate between the distributions.
