the effect of symmetric (non-symmetric) foreign exchange rate shocks on iranian agricultural import and exports was explored throughout the current research.. time series of 1973-2007 along with hodrick and prescott filter method were employed. the results as obtained through vector error correction and johnson model indicated that positive (negative) shocks introduce positive (negative) effect...

The degree to which measurement accuracy in a vector network analyzer can be improved through error correction is dependent on a number of factors. Modern error correction methods have improved the system accuracy and simplified the calibration procedure. Methods are in place to determine the accuracy of error corrected measurements. And the quality of the calibration standards is key to system...

We propose a simplified version of the Kitaev’s surface code in which error correction requires only three-qubit parity measurements for Pauli operators XXX and ZZZ. The new code belongs to the class of subsystem stabilizer codes. It inherits many favorable properties of the standard surface code such as encoding of multiple logical qubits on a planar lattice with punctured holes, efficient dec...

Abstract This article is an empirical attempt to explore the relationship between sanctions (financial and non-financial), oil price shocks and Iran-Russian bilateral trade flows over the period 1991–2014. In contrast to earlier studies in which a gravity model has been estimated through a panel data approach, in this paper the authors apply a gravity model for only two countries and do the es...
