This study proposed a natural-rule-based-connection (NRBC) method to connect river segments after water body detection from remotely sensed imagery. A complete river network is important for many hydrological applications. While water body detection methods using remote sensing are well-developed, less attention has been paid to connect discontinuous river segments and form a complete river net...
background: asphyxia is a common cause of perinatal mortality in 5-10% of all births worldwide. the present parameters for determining perinatal asphyxia, e.g. preeclampsia, cannot be considered as markers per se, and require auxiliary markers, e.g. increased number of nucleated red blood (nrbc) cells, for early diagnosis of perinatal asphyxia. objective: in this study, we evaluated the mean nr...
Considering the incidence of meconium-stained amniotic fluid (MSAF) in newborns and its complications, and also based on indirect reports pointing out relationship between nucleated red blood cell (nRBC), as a marker of chronic hypoxia, and MSAF in term newborns, and in order to determine this relationship more accurately, this study was done on women with uncomplicated singleton term pregnancy...
Myelodysplastic syndromes (MDS) are clonal stem cell disorders which frequently show a hypercellular dysplastic bone marrow (BM) associated with inefficient hematopoiesis and peripheral cytopenias due to increased apoptosis and maturation blockades. Currently, little is known about the role of cell proliferation in compensating for the BM failure syndrome and in determining patient outcome. Her...
Background: Intraventricular hemorrhage (IVH) is one of the most serious complications of premature deliveries, especially in very low birth weight (VLBW) newborns. The current study compared the number of nucleated red blood cells (NRBCs) in newborns with and without IVH.Methods: This cross-sectional study was carried out on 109 VLBW neonates who were referred to the Neonatal Intensive C...
We report in this paper a fast and accurate algorithm for computing the exact spherical nonreflecting boundary condition (NRBC) for time-dependent Maxwell’s equations. It is essentially based on a new formulation of the NRBC, which allows for the use of an analytic method for computing the involved inverse Laplace transform. This tool can be generically integrated with the interior solvers for ...
Problems of linear time-dependent dispersive waves in an unbounded domain are considered. The infinite domain is truncated via an artificial boundary B, and a high-order non-reflecting boundary condition (NRBC) is imposed on B. Then the problem is solved by a finite difference (FD) scheme in the finite domain bounded by B. The sequence of NRBCs proposed by Higdon is used. However, in contrast t...
The purpose of this study was to determine acceptability of the nucleated red blood cells counts (NRBC) as early prognostic parameter for adverse outcome in preterm neonates born from pregnancies complicated with severe preeclampsia. We analysed 77 premature newborns who were born from pregnancies with severe preeclampsia during eight years (2004-2011) in our tertiary center. Women with other p...
BACKGROUND Perinatal asphyxia is a major cause of neurologic morbidity and mortality. The purpose of this study was to investigate variations in nucleated red blood cell (NRBC) count per 100 white blood cells (WBC) and absolute NRBC/mm3 in blood associated with perinatal asphyxia and its relationship to both the severity and short term prognosis of asphyxia. METHODS A prospective (case-contro...
Introduction: Increased numbers of nucleated red blood cells (NRBC) circulating in the blood of neonates can be associated with relative hypoxia and adverse outcomes. Thus, the aim of this study was to assess the NRBC count during the first week of life in neonates diagnosed with asphyxia as compared to healthy neonates and to determine the short-term morbidity and mortality for the affected ba...
