BACKGROUND Characterising intra and inter-subject variability of motor-evoked potential (MEP) measurements from transcranial magnetic stimulation (TMS) is key to its development as a diagnostic tool. METHODS We performed three experiments to elucidate MEP variability within subjects: (i) repeated measurements at different levels of stimulation and muscle(More)
Xenograft trials allow tumor growth in human cell lines to be monitored over time in a mouse model. We consider the problem of inferring the effect of treatment combinations on tumor growth. A piecewise quadratic model with flexible phase change locations is proposed to model the effect of change in therapy over time. Each piece represents a growth phase,(More)
This paper presents a method for semi-automatic analysis of morphometry in image cytometry studies. We examine morphological changes in neuroblastoma cells caused by a toxin. Nuclei are automatically recognized from images using a constrained seeded region growing algorithm. The shape of the nuclei is quantified by fitting ellipses to the identified(More)
