In a nano-ridge waveguide under oblique illumination, we demonstrated transmission enhancement resulting from a hybrid effect between propagation modes and surface plasmon wave. The measured near-field intensity with 44-degree illumination was 1.6 times higher than that illuminated with normal incident light. Consequently, a wedge-shaped fiber probe was proposed to serve as a compact near-field...

An unfolding of a polyhedron P is obtained by ‘cutting’ the surface of P in such a way that it can be flattened into the plane into a single polygon. For most practical and theoretic applications, it is desirable for an algorithm to produce an unfolding which is simple, that is, non-overlapping. Currently, two methods for unfolding which guarantee non-overlap for convex polyhedra are known, the...

various dermatoglyphic parameters like finger print pattern, atd angle, absolute ridge count & ab, bc ,cd, and ad ridge counts were observed in 150 cases of congenital cardiac disease, comprising of 72 cases of ventricular septal defects (vsd), 60 cases of atrial septal defects (asd), 9 cases of coarctation of aorta (coa) & 9 cases of tetralogy of fallot’s (tof). same dermatoglyphic parameters ...

Herein, the mid-infrared (7.7–13.7 ?m) diamond-based phase shifter was designed and optimized by finite-element analysis. The ridge-shaped diamond waveguide is doped to form internal p–n structure, carrier distribution changed applying forward reverse voltages change effective refractive index achieve effect of ?-phase shift. results show that when p-doping concentration 4 × 1017 cm?3 n doping ...

BACKGROUND An epidermoid cyst is a common epithelial-lined cyst. There have been many studies on epidermoid cysts, but few focused on ruptured epidermoid cyst and its histopathologic characteristics. OBJECTIVE We evaluated the histopathologic differences between ruptured and unruptured epidermoid cysts, and their relationships. METHODS We retrospectively examined 359 excision biopsy specime...

OBJECTIVE The aim of this study was to determine the effect of different palatal vault shapes on the dimensional stability of a glass fiber reinforced heat polymerized acrylic resin denture base material. METHODS Three edentulous maxilla with shallow, deep and medium shaped palatal vaults were selected and elastomeric impressions were obtained. A maxillary cast with four reference points (A, ...

Asteroid (162173) Ryugu was the first spinning-top-shaped asteroid to be closely approached by a probe, Hayabusa2 spacecraft, which sent numerous high-resolution images of Earth and revealed nature this type asteroid. One notable features is equatorial ridge, considered result rapid spin in past. Despite advanced age indicated presence craters, ridge exhibits bluish color, indicating that it co...

PURPOSE The purpose of this study was to investigate the influence of mandibular residual ridge shape on the masticatory ability in complete denture wearers. METHODS The subject group consisted of 199 complete denture wearers. The mandibular residual ridge of each subject was evaluated using a replica of the ridge which was obtained with heavy-body silicone impression material. The basal area...
