This thesis presents a theory of 3-D imaging in partially coherent light under a non-paraxial condition. The transmission cross-coefficient (TCC) has been used to characterize partially coherent imaging in a 2D and 3-D paraxial model. It is shown that the 3-D TCC under the non-paraxial condition is an overlap integral of three hemispheres or 3-D pupil functions. By an inspection of the overlap ...

In this paper, we introduce a cone generalized semi-cyclicφ−contraction maps and prove best proximity points theorems for such mapsin cone metric spaces. Also, we study existence and convergence results ofbest proximity points of such maps in normal cone metric spaces. Our resultsgeneralize some results on the topic.

We performed an evaluation of the CyberKnife InCise MLC by comparing plan qualities for single and multiple brain lesions generated using the first version of InCise MLC, fixed cone, and Iris collimators. We also investigated differences in delivery efficiency among the three collimators. Twenty-four patients with single or multiple brain mets treated previously in our clinic on a CyberKnife M6...

Photobiomodulation is used to accelerate tooth movement during orthodontic treatments. The changes in root morphology in a group of orthodontic patients who received photobiomodulation were evaluated using the cone beam computed tomography technique. The device used is called OrthoPulse, which produces low levels of light with a near infrared wavelength of 850 nm and an intensity of 60 mW/cm(2)...

[1] The combination of the Wang-Sheeley-Arge (WSA) coronal model, ENLIL heliospherical model version 2.7, and CONED Model version 1.3 (WSA-ENLIL with CONED Model) was employed to form ensemble forecasts for 15 halo coronal mass ejections (halo CMEs). The input parameter distributions were formed from 100 sets of CME cone parameters derived from the CONED Model. The CONED Model used image proces...

PURPOSE To evaluate the effectiveness of internal fixation versus cone hemiarthroplasty for the treatment of unstable intertrochanteric fractures in elderly patients. METHODS The choice of treatment was based on the year of admission: between 2001 and 2003, 42 patients (mean age, 73 years) underwent cone hemiarthroplasty using a cementless press fit through a posterior approach, whereas betwe...

Let A be an element of the copositive cone COP. A zero u of A is a nonnegative vector whose elements sum up to one and such that uTAu = 0. The support of u is the index set suppu ⊂ {1, . . . , n} corresponding to the nonzero entries of u. A zero u of A is called minimal if there does not exist another zero v of A such that its support suppv is a strict subset of suppu. Our main result is a char...

Considering the importance of determining potential hazards and factors that can cause anunexpected fire and due to the important role of nanotechnology to achieve more effectiveproperties, this paper presents our experiments on preparing nanocomposites based onPoly(ethylene terephthalate)(PET) and montmorillonite (MMT) as organoclay via meltblending with different clay loadings to investigate ...
