Background: It is suggested that HA-1 mismatching among hematopoietic stem cell transplanted recipients-donors is associated with acute graft-versus-host disease (aGVHD). So the aim of this study was to evaluate HA-1 frequency and examine the correlation between HA-1 disparity and GVHD patients who received transplantation from a HLA-identical sibling. Samples and Methods: the DNA was extracted...

INTRODUCTION Major efforts have been made to improve the health care system in Hunan province, China. The aims of this study were to assess whether and to what extent these efforts have impacted on gender and regional disparities of Tuberculosis (TB) incidence in recent years, especially for less developed areas. METHODS We obtained data from the 2005-2009 China Information System for Disease...

In this paper, we propose a new and simple approach to obstacle and free space detection in an indoor and outdoor environment in real-time using stereo vision as sensor. The real-time obstacle detection algorithm uses two dimensional disparity map to detect obstacles in the scene without constructing the ground plane. The proposed approach combines an accumulating and thresholding techniques to...

purpose: to determine stereopsis with local (titmus) and global (tno) tests in symptomatic and asymptomatic subjects according to induced disparity (crossed or uncrossed). methods: in this cross sectional study, 80 students of zahedan university of medical sciences who fulfilled the inclusion criteria were randomly selected. at first, refractive error was determined by retinoscopy and then base...

industrial revolution, colonialism and spreading of patterns of development and consequently the vast rural and urban migrations and centralism in recent century caused the creation of unbalanced population distribution pattern in iran. in addition to areas in which inequalities of environmental and productive resources increase space disparity of distribution of populations, in arease like aze...

In depth cue-conflict conditions, various depth cues could represent different extents of depth. Previous studies have investigated the perceived size of negative afterimage in depth cue-correlated conditions in which different cues introduce almost the same amounts of depth to the visual system. This study examined the perceived size of the afterimage in the human observers in a condition that...

The Healthy People 2010 initiative challenges us to measure progress toward the reduction of disparities among subgroups in the population. Pair-wise comparisons provide specific information about absolute or relative differences between rates. Changes in disparity between two groups can be measured by comparing the disparity between rates at one point in time with the disparity between compara...

In this paper, we present a cooperative stereo vision algorithm with three cameras for dense disparity mapping and occlusion detection. Based on nonlinear iteration and multiple cameras, the disparity maps are smooth and the object boundaries are accurate. Occlusions for each stereo pair are detected effectively by examining the iterative inhibition and magnification of the matching evaluation....

Abstrct The detection of ground plane and free space remains challenging for non-flat plane, especially with the varying latitudinal and longitudinal slope or in the case of multi-ground plane. In this paper, we propose a framework of the ground plane detection with stereo vision. The main contribution of this paper is a newly proposed descriptor which is implemented in the disparity image to o...
