this paper uses a multivariate garch model to simultaneously estimate the mean and conditional variance using daily returns among different tehran sector indexes from tir 1386 to tir 1391. since different financial assets are traded based on these sector indexes, it is important for financial market participants to understand the volatility transmission mechanism over time and across sectors in...

Two perspectives stand out in examining international variations innovative new venture creation: institutions and national culture.

Assessment of FTR is challenging due to the complex anatomy of both the TV and the RV. However, identification of the mechanism of regurgitation, reliable grading of its severity, accurate quantitative data about extent of TV tethering, TA dilatation, and RV enlargement are crucial for selecting patients who may benefit of early surgical repair and tailor the intervention in order to avoid prog...

The phrase 'bury your head in the sand' means failure to acknowledge a problem. It emanates from the habit of ostriches who hide when faced by predators with the critically flawed assumption that if you can't see it, it can't see you. The obvious shortcoming of Surgeon Specific Mortality Data (SSMD) is the premise that the surgeon bears responsibility for all post-operative deaths irrespective ...

The reduction of ferredoxin-thioredoxin reductase (FTR) by plant-type ferredoxin plays an important role in redox regulation in plants and cyanobacteria. Nuclear magnetic resonance (NMR) was used to map the binding sites on Synechocystis ferredoxin for FTR. A gallium-substituted structural analog of this [2Fe-2S] ferredoxin was obtained by reconstituting the apoprotein in a refolding buffer con...
