Aims This study assessed the effect of access design on angle, radius, and location of primary canal curvature in mesial roots of Type IV mandibular molars at different phases of root canal preparation. Methodology Twenty-four teeth were selected radiographically and via μCT and accessed with contracted (CEC; n = 12) or traditional endodontic cavity (TEC; n = 12) designs. Angle, radius, and loc...

Non-steroidal anti-inflammatory drugs and COX-2 inhibitors bind to COX-2 and provide relief from the symptoms of pain and inflammation. However, they lack anti-thrombotic activity and hence lead to cardiovascular and renal liabilities apart from gastrointestinal irritation. J Martel-Pelletier et al. reported that dual 5-LOX/COX inhibitors are potential new drugs to treat inflammation. They act ...

Dislocation dynamics simulations of the interaction between prismatic dipolar loops and a glide screw dislocation are presented. As a result of stress gradients generated by the glide dislocation, dipolar loops execute drift motion along their glide cylinders. Simulations of the combined motion of two dipolar loops in the stress field of a glide dislocation clearly show that inter-loop forces a...

When a long glide with a short temporal gap in its middle crosses with a continuous short glide at the temporal midpoint of both glides, the gap is perceived in the short glide instead of in the long glide. In the present article, we tested possible explanations for this "gap transfer illusion" by obtaining points of subjective equality of the pitches and durations of the two short tones that a...

Generative phonologists usually take high vowels like [i,u] and glides like [j,w] to be identical (respectively) in terms of distinctive features. The main argument for this assumption comes from theoretical economy: since syllable theory independently provides us with a means of distinguishing between vowels and glides – as syllable nuclei and margins respectively – there is no need for a feat...

Glide's ability to identify active compounds in a database screen is characterized by applying Glide to a diverse set of nine protein receptors. In many cases, two, or even three, protein sites are employed to probe the sensitivity of the results to the site geometry. To make the database screens as realistic as possible, the screens use sets of "druglike" decoy ligands that have been selected ...

Two Doppler LIght Detection And Ranging (LIDAR) systems have been operated by the Hong Kong Observaotry (HKO) at the Hong Kong International Ai rport (H KIA) for the det ection and alerting of low-level windshear to be encountered by the aircraft. The windshear al erting algorithm is based on the automatic identification of abrupt changes of headwinds along the glide paths of HKIA, which are me...
