Accelerometers are becoming more widely used in the assessment of physical activity in children, and converting the output to min of moderate-to-vigorous physical activity (MVPA) requires the use of age-specific cut-off point definitions. However, numerous cut-off points are available among children, and different cutoff point definitions of MVPA have been used in different studies. Comparison ...
We show that only the segment borders have to be taken into account as cut point candidates in searching for the optimal multisplit of a numerical value rangewith respect to convex attribute evaluation functions. Segment borders can be found efficiently in a linear-time preprocessing step. For strictly convex evaluation functions inspecting all segment borders is also necessary. With Training S...
In multicast routing, one of the basic problems consists of sending data from a set of sources to a set of destinations with minimum cost. A formalization of this problem using graph theory is given by the nonfixed Point-to-Point Connection (PPC) Problem. The optimization version of this problem is known to be NP-hard, and it can be also applied in areas such as circuit switching and VLSI desig...
INTRODUCTION Our goal was to develop cut points for amyloid positron emission tomography (PET), tau PET, flouro-deoxyglucose (FDG) PET, and MRI cortical thickness. METHODS We examined five methods for determining cut points. RESULTS The reliable worsening method produced a cut point only for amyloid PET. The specificity, sensitivity, and accuracy of cognitively impaired versus young clinica...
