Purpose: To review drusen and sub retinal drusenoid deposits in age related macular degeneration as regards their pathogenesis, morphology, differentiation and their importance as regards the visual prognosis of age related macular degeneration (AMD). Results: Each type of drusen or drusenoid deposits has a different visual prognosis, and the differentiation of them using multimodal imaging tes...

BACKGROUND Person-centered reproductive health care is recognized as critical to improving reproductive health outcomes. Yet, little research exists on how to operationalize it. We extend the literature in this area by developing and validating a tool to measure person-centered maternity care. We describe the process of developing the tool and present the results of psychometric analyses to ass...

the response of karoun basin in lumped and semi-distributed simulation were compared. also, the flood intensity of the sub-basins and the effects of physical parameters on flood hydrograph have been investigated. results demonstrated that there was no significant difference between the characteristics of flood hydrograph in lumped and semi-distributed simulation. also, results showed that the f...

Efficiency of optimistic fair exchange using trusted devices is studied. Pfitzmann, Schunter and Waidner (PODC 1998) have shown that four messages in the main sub-protocol is optimal when exchanging idempotent items using non-trusted devices. It is straightforward that when using trusted devices for exchanging nonidempotent items this number can be reduced to three. This however comes at the co...

In this paper we study an allocation and scheduling problem with maintenance constraints. It consists of two difficult sub-problems: a resource allocation sub-problem and a maintenance scheduling sub-problem. A Column Generation model is proposed to solve this problem. In order to be able to find optimal solutions for the relaxed (non integer) problem a model based on a graph with supernodes ha...

background: magnetic resonance imaging (mri) has improved the diagnosis and management of patients with multiple sclerosis (ms). montreal cognitive assessment (moca) is a brief, sensitive test that has been recommended by national institute of neurological diseases and stroke and canadian stroke network (ninds-csn) as a reliable tool to detect mild cognitive impairments. this study aimed to eva...

This paper has two objectives: (a) to provide a clear description of three methods for controlling the maximum exposure rate in computerized adaptive testing -the Symson-Hetter method, the restricted method, and the item-eligibility method- showing how all three can be interpreted as methods for constructing the variable sub-bank of items from which each examinee receives the items in his or he...
