The dimensional change card-sorting task (DCCS task) is frequently used to assess young children's executive abilities. However, the source of children's difficulty with this task is still under debate. In the standard DCCS task, children have to sort, for example, test cards with a red cherry or a blue banana into two boxes marked with target cards showing a blue cherry and a red banana. Typic...

OBJECTIVE The objective of this study was to compare the surface morphology and dimensional stability of the bracket slot at the onset of treatment and after 12 months of intraoral exposure. The study also compared the amount of calcium at the bracket base which indicates enamel loss among the three orthodontic brackets following debonding after 12 months of intraoral exposure. MATERIALS AND ...

Nonlinear time series analysis techniques have been used to analyze physiologic signals such as EEG and heart rate. The authors illustrate the application of dimensional analysis (DA) to assess neonatal sleep states at increasing gestational ages up to full-term age. One hundred and sixteen EEG-polygraphic recordings were performed on 55 neonatal subjects between 28 and 43 weeks gestational age...

In this paper I present the model of ‘bounded revision’ that is based on two-dimensional revision functions taking as arguments pairs consisting of an input sentence and a reference sentence. The key idea is similar to the model of ‘revision by comparison’ investigated by Fermé and Rott (Artificial Intelligence 157, 2004). In contrast to the latter, however, bounded revision satisfies the AGM a...

The effectiveness of change-detection algorithms is often assessed on real-world datasets by injecting synthetically generated changes. Typically, the magnitude of the introduced changes is not controlled, and most of experimental practices lead to results that are difficult to reproduce and compare with. This problem becomes particularly relevant when the datadimension scales, as it happens wi...

The method of change (or anomaly) detection in high-dimensional discrete-time processes using a multivariate Hotelling chart is presented. We use normal random projections as a method of dimensionality reduction. We indicate diagnostic properties of the Hotelling control chart applied to data projected onto a random subspace of R. We examine the random projection method using artificial noisy i...

Accelerated partial breast irradiation is commonly done with the MammoSite applicator, which requires symmetry to treat the patient. This paper describes three cases that were asymmetric when initially placed and became symmetric over time, without manipulation.

The electrically operated phase-change random access memory (PRAM) features faster write/read, improved endurance, and much simpler fabrication as compared with the traditional transistor-based nonvolatile semiconductor memories. Low-dimensional phase-change materials in nanoscale dimensions offer advantages over their bulk or thin-film counterpart in several aspects such as reduced programmabl...

PURPOSE The final goal of regenerative periodontal therapy is to restore the structure and function of the periodontium destroyed or lost due to periodontitis. However, the role of periosteum in periodontal regeneration was relatively neglected while bone repair in the skeleton occurs as a result of a significant contribution from the periosteum. The aim of this study is to understand the histo...
