Glide formation, a process whereby an underlying high front vowel is realized as a palatal glide, is shown to occur only in unstressed prevocalic position in German, and to be blocked by specific surface restrictions such as *ji and *“j. Traditional descriptions of glide formation (including derivational as well as Optimality theoretic approaches) refer to the syllable in order to capture its c...

Passive vision techniques to estimate aircraft position during landing can be developed using a runway model, images acquired by onboard imaging sensor, orientation information provided by the inertial navigation system and the position estimate provided by devices such as the global positioning system. In this paper expressions are derived for the sensitivity of point features to errors in the...

We report that kink motion is a universal plastic deformation mode in all carbon nanotubes when being tensile loaded at high temperatures. The kink motion, observed inside a high-resolution transmission electron microscope, is reminiscent of dislocation motion in crystalline materials: namely, it dissociates and multiplies. The kinks are nucleated from vacancy creation and aggregation, and prop...

Glial cells differentiate from the neuroepithelium. In flies, gliogenesis depends on the expression of glial cell deficient/glial cell missing (glide/gcm). The phenotype of glide/gcm loss- and gain-of-function mutations suggested that gliogenesis occurs in cells that, by default, would differentiate into neurons. Here we show that glide/gcm is able to induce cells even from a distinct germ laye...

NiTi instrument separation is a serious concern in endodontic therapy. The analysis of NiTi files after torsional fracture reveals that the majority of torsional separations occur in the last mm. of the files and in the files with lower taper and/ or diameter. Consequentely, the tip of the smaller files presents the higher risk of torsional fracture and should be protected using low torque moto...

The end game is an oft forgotten phase in a software project, despite the fact it can make or break a project. Successful project managers and technical leads seek to ensure their project follows a controlled glide path to a successful conclusion. However, things can and will go wrong and then success is characterized by an ability to adapt and change to meet and manage new challenges. Patterns...

In the clinical practice, it is much more efficient to use NiTi rotary files compared to hand instrumentation. However, misuse of NiTi rotary files can result in procedural errors such as transportation, ledge, perforation, and file separation. Generally, following suggestions could be considered to avoid these errors. 1. Enlarge the coronal half of the root canal before preparing the apical pa...

Alternations involving place-changing palatalization (e.g. t+j  ʧ in spirit – spiritual) are very common and have been a focus of much generative phonological work since Chomsky & Halle’s (1968) ‘Sound Pattern of English’. The interest in palatalization and its mechanisms (see e.g. Sagey 1990; Chen 1996; Bateman 2007) has somewhat obscured the question of how these processes fit into a wider t...

In the system being developed for accessing lexical items from the speech signal, an initial step is to identify landmarks which indicate the presence of vowel, glide, and consonant segments. This thesis addresses the problem of identifying the glide landmarks. The acoustic properties measured to locate glide landmarks are based on a model of glide production. This model states that a tight con...
