super eciency data envelopment analysis(dea) model can be used in ranking the performanceof ecient decision making units(dmus). in dea, non-extreme ecient unitshave a super eciency score one and the existing super eciency dea models do notprovide a complete ranking about these units. in this paper, we will propose a methodfor ranking the performance of the extreme and non-extreme ecient u...
Severe combined immunodeficiency is a rare, fatal syndrome of diverse genetic cause in which there is combined absence of T-lymphocyte and B-lymphocyte function (and in many cases also natural killer, or NK lymphocyte function). These defects lead to extreme susceptibility to serious infections. Without intervention, the T and B-cell dysfunction usually results in severe infection and death in ...
desmoids tumors, characterized by monoclonal proliferation of myofibroblasts, could occur in 5-10% of patients with familial adenomatous polyposis (fap) as an extra-colonic manifestation of the disease. fap can develop when there is a germ-line mutation in the adenomatous polyposis coli gene. although mild or attenuated fap may follow mutations in 5΄ extreme of the gene, it is more likely that ...
Purpose: Morphological dental anomalies of the maxillary lateral incisors are relatively common. However, their simultaneous occurrence is a relatively rare event. We report a case of dens invaginatus and talon cusp concurrently affecting maxillary lateral incisors. The etiology, pathophysiology, association with other dental anomalies, as well as various treatment modalities of these anomalies...
Super eciency data envelopment analysis(DEA) model can be used in ranking the performanceof ecient decision making units(DMUs). In DEA, non-extreme ecient unitshave a super eciency score one and the existing super eciency DEA models do notprovide a complete ranking about these units. In this paper, we will propose a methodfor ranking the performance of the extreme and non-extreme ecient units.
abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
s:1750:"Background: We propose in this work to assess the effect of total and severe teratozoospermia on the outcome of intra cytoplasmic sperm injection( ICSI) essentially the biological side and try to highlight the factor in the success or failure of the attempt in cases of extreme or total teratozoospermia. Materials and Methods: This is a comparative retrospective study including 140 coupl...
Research on the roots and causes of dangerous phenomenon of exaggeration, ghuluv, mainly appeared as overstating Shiite Imams, is of considerable important. Needless to say, exact acquaintance to the roots and causes of exaggeration, in many cases, would support people against this danger. Relying on precedent historical, traditional, sectarian documents and noting to different views in the fie...
In this paper, presenting two simple methods for ranking of efficient DMUs in DEA models that included to add one virtual DMU as ideal DMU and is using the additive model. Note that, we use an ideal point just for comparing efficient DMUs with. Although these methods are simple, they have ability for ranking all efficient DMUs, extreme points and the others, also they are capable of ranking t...
