objectives: differential diagnosis of bifid mandibular condyle (bmc) is important, since it may play a role in temporomandibular joint (tmj) dysfunctions and joint symptoms. in addition, radiographic appearance of bmc may mimic tumors and/or fractures. the aim of this study was to evaluate the prevalence and orientation of bmc based on cone beam computed tomography (cbct) scans.   materials and...

introduction: due to the complexity of facial asy-mmetry, the diagnosis of different aspects of asymmetry via conventional radiographs is not precise. in this study, we investigated findings of facial asymmetry by using cone- beam computed tomography (cbct) images. materials and methods: in this descriptive study, we evaluated cbct findings of 18 patients i.e. a group of 14 females and 4 males ...

Cone photoreceptors in fish are typically arranged into a precise, reiterated pattern known as a "cone mosaic." Cone mosaic patterns can vary in different fish species and in response to changes in habitat, yet their function and the mechanisms of their development remain speculative. Zebrafish (Danio rerio) have four cone subtypes arranged into precise rows in the adult retina. Here we describ...

recently, choudhury and metiya [fixed points of weak contractions in cone metric spaces, nonlinear analysis 72 (2010) 1589-1593] proved some fixed point theorems for weak contractions in cone metric spaces. weak contractions are generalizations of the banach's contraction mapping, which have been studied by several authors. in this paper, we introduce the notion of $f$-weak contractions and als...

In this paper, we have studied the hydrogen adsorption onto CNCs and BNNCs nano-cones using GCMC simulations. The effects of length and cone apex angle on adsorption property have been investigated. Our results show that with increasing the pressure and decreasing the cone length and cone apex angle except for CNC-300˚, the hydrogen adsorption onto the BNNCs and CNCs was increased. It was also ...

OBJECTIVE To identify key factors for predicting positive cone margin and appropriate cone length. METHODS We retrospectively reviewed the margin status of patients who received conization with high grade cervical intraepithelial neoplasia, along with other factors such as patient age, parity, preoperative cytology, size of disease, type of transformation zone, and cone length from patient re...

Foveal cone spacing was measured in vivo using an objective technique: ocular speckle interferometry. Cone packing density was computed from cone spacing data. Foveal cone photopigment density difference was measured in the same subjects using retinal densitometry with a scanning laser ophthalmoscope. Both the cone packing density and cone photopigment density difference decreased sharply with ...
