Objectives It was aimed to compare the cyclic fatigue resistances of ProGlider (PG), One G (OG), and HyFlex EDM (HEDM) nickel titanium glide path files in single- and double-curved artificial canals. Materials and Methods 40 PG (16/0.02), 40 OG (14/0.03), and 40 HEDM (10/0.05) single-file glide path files were used in the present study. Sixty files were subjected to cyclic fatigue test by usi...

The application of surface diathermy to the sclera, followed by ophthalmoscopic observation of the choroido-retinal reaction, is a time-honoured technique which may be used with shallow detachments; it fails with deep detachments, as no reaction can then be seen with the ophthalmoscope. Stallard (1958) advocated the focusing of a narrow beam of light from an ophthalmoscope on to the retinal hol...

We tested the hypothesis that common principles govern the production of the locomotor patterns for both straight-ahead and curved walking. Whole body movement recordings showed that continuous curved walking implies substantial, limb-specific changes in numerous gait descriptors. Principal component analysis (PCA) was used to uncover the spatiotemporal structure of coordination among lower lim...

Fascinating and elegant shapes may be folded from a single planar sheet of material without stretching, tearing or cutting, if one incorporates curved folds into the design. We present an optimizationbased computational framework for design and digital reconstruction of surfaces which can be produced by curved folding. Our work not only contributes to applications in architecture and industrial...

Few computer implementations of shape grammars have been written that are applicable to curved shapes. The reason for this is that underlying representations of curves do not lend themselves to providing a unique description of curved shapes. Such a representation is essential for shape algorithms. This paper explains the problems posed in representing curves for shape grammar implementation. T...
