there are many different ways to subdivide the spectrum of a bounded linear operator; some of them aremotivated by applications to physics (in particular, quantum mechanics). in this study, the relationship betweenthe subdivisions of spectrum which are not required to be disjoint and goldberg's classification are given.moreover, these subdivisions for some summability methods are studied.
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
a secundum atrial septal defect is the most common congenital heart defect. transcatheter treatment of secundum atrial septal defects is a popular and less invasive alternative to surgery. procedural complications may occur in a wide spectrum, particularly device embolus as the most emergent one, but luckily they do not commonly occur in the clinical setting. mortality from adverse events relat...
In this paper, the electronic transport of a graphene nanoribbon including a bond defect as well as a polyacetylene nanowire, including an extra bond, has been studied based on Green's function technique at the tight-binding approach. The results show that the behavior of electronic conductance is different in resonance and nonresonance cases with respect to variation of bond defect position. T...
purpose: to present a case of unilateral epibulbar dermoid cyst in a girl with vacterl syndrome. case report: a 4-year-old girl was referred with a white, soft and painless mass in the inferotemporal limbus of the left eye having presented since birth. the patient was healthy with normal growth. other ocular examinations were normal. systematic review revealed a group of abnormalities including...
Background: Joint attention has received a lot of attention by researchers and specialists of autism spectrum disorder in recent years and refers to a developmental skill resulting in joining attention or processing messages of others. Defect in growth of joint attention is particular to children with autism spectrum disorder and is one of the symptoms for diagnosing autism spectrum disorder in...
A simple method is introduced for analyzing error score distributions from the Farnsworth-Munsell 100-Hue test. The method involves fitting a sine wave directly to the error distribution, and produces estimates of three parameters that characterize the severity of the defect, the degree of bipolarity, and the orientation of the axis of bipolarity, if one is present. The method produces good est...
