Abstract What do football passes and financial transactions have in common? Both are networked walk processes that we can observe, where records take the form of timestamped events move something tangible from one node to another. Here propose an approach analyze this type data extracts actual trajectories taken by items involved. The main advantage analyzing resulting compared using, e.g., exi...

Researchers have identified trajectories of pain derived using statistical techniques on longitudinal data. These trajectories have potential to be of use clinically but the repeated data collection required is currently impractical for such situations. Our aim was to investigate the validity of a self-report (Visual Trajectories Questionnaire-Pain) for pain. Analysis included participants from...

In this paper, we study the transport of air masses to San Pietro Capofiume (SPC) in Po Valley, Italy, by means of back trajectories analysis. Our main aim is to investigate whether air masses originate over different regions on nucleation event days and on nonevent days, during three years when nucleation events have been continuously recorded at SPC. The results indicate that nucleation event...

This work compares two ways of spiral scanning in MRI, i.e., scanning with an odd or with an even number of k-space trajectories. Within each scan, the angles between adjacent trajectories are equal to each other. On the condition that prior correction for experimental phase distortion of the image be feasible, we show that an odd number of trajectories yields about twice as much information as...

OBJECTIVE Previous studies on developmental trajectories have used ad hoc definitions of oppositional defiant behaviors (ODB), which makes it difficult to compare results. This article defines developmental trajectories of ODB from ages 3-5 based on five different standard measurements derived from three separate instruments. METHOD A sample of 622 three-year-old preschoolers, followed up at ...
