AIM The aim of this study was to compare sizes of the first instrument with or without a taper that binds at the apical constriction of a root canal after coronal flaring. METHODS AND MATERIALS A total of 310 canals were evaluated in patients presenting for root canal therapy. Canals with intact apices were selected. After gaining straight line endodontic access, the coronal third was flared ...

Accurate and effective voice activity detection (VAD) is a fundamental step for robust speech or speaker recognition. In this study, we proposed a hierarchical framework approach for VAD and speech enhancement. The modified Wiener filter (MWF) approach is utilized for noise reduction in the speech enhancement block. For the feature selection and voting block, several discriminating features wer...

This paper introduces the topic of " Collaborative Distance " within Distributed Collaboration as being an introduction to this Special Issue on Collaborative Working Environments 1 (CWE). It starts in discussing various related concepts, identified during an extensive literature review, on both proximity and distance in distributed collaboration. Then, a Collaborative Distance Framework (CDF) ...

We propose a new approach to commutative watermarkingencryption (CWE). A permutation cipher is used to encrypt the multimedia data, which leaves the global statistics of the multimedia data intact. Therefore, any non-localized watermarking scheme that depends only on global statistics of the multimedia data can be combined with the permutation cipher to form a CWE scheme. We demonstrate this ap...

Numerous studies have shown that older adults exhibit deficits in motor sequence learning, but the mechanisms underlying this effect remain unclear. Our recent work has shown that visuospatial working-memory capacity predicts the rate of motor sequence learning and the length of motor chunks formed during explicit sequence learning in young adults. In the current study, we evaluate whether age-...
