In this paper we develop a simulator modeling a kidney exchange program, in which donor-recipient pairs with characteristics drawn from a distribution based on real data join the system over time, and a centralized authority organizes a suitably chosen set of exchanges among the pairs in the pool at regular intervals of time, as it happens in the Netherlands or in the US. We compare and discuss...

exchange rate and national income of countries trading with each other are among the most important factors affecting each country's trade. considering the political and economic ties between iran and venezuela in recent years, the goal of this paper was to investigate the effect of exchange rate volatility on exports of iran to venezuela. data used in this research include annual data for...

Computational intelligence approaches have gradually established themselves as a popular tool for forecasting the complicated financial markets. Forecasting accuracy is one of the most important features of forecasting models; hence, never has research directed at improving upon the effectiveness of time series models stopped. Nowadays, despite the numerous time series forecasting models propos...

This study examines the impacts of real exchange rate fluctuations on the companies' strategic investments in Iran. The data of 92 listed companies in Tehran Stock Exchange during the period of 2002-2015areused. First, the volatility of exchange rate is estimated by the Generalized Autoregressive Conditional Heteroskedasticity (GARCH). The model is estimated by GMM and system GMM methods. The r...

this study was conducted to evaluate the effect of purslane hydro alcoholic extract on blood urea nitrogen (bun), creatinine (cr) and kidney histopathology of kidney aging model induced by d-galactose in female mice. in this experimental study, 72 female naval medical research institute (nmri) mice (30-35 g) were randomly divided into six groups including: control, purslane, d-galactose, d-gala...

With cross-over living donor kidney transplantation, immunologic incompatibilities within the original donor/recipient pair can be overcome. As minimal invasive techniques for organ recovery are increasingly applied, this should also be performed in a cross-over kidney transplantation. We present the first report of a successful simultaneous laparoscopic kidney recovery for cross-over kidney tr...

PURPOSE Multislice maps of extracellular pH (pHe) are needed to interrogate the heterogeneities of tumors and normal organs. To address this need, we have developed a multislice chemical exchange saturation transfer (CEST) MRI acquisition method with a CEST spectrum-fitting method that measures in vivo pHe over a range of 6.3 to 7.4. METHODS The phase offset multiplanar (POMP) method was adap...

exchange rate has the fundamental role as one of the economy key variables in determining the domestic price. so it is important to know how is the empirical relationship between the exchange rate and domestic prices and the factors influencing this relationship. the main objective of this study is to determine the effect of vehichel imports share on the exchange rate pass – through on domestic...
