We consider the fidelity of vector meson dominance (VMD) assumption as an instrument for relating electromagnetic vector-meson production reaction $e + p \to e^\prime V p$ to purely hadronic process $V V+p$. Analyses photon vacuum polarisation and photon-quark vertex reveal that such a VMD Ansatz might be reasonable light vector-mesons. However, when vector-mesons are described by momentum-depe...

Abstract The problem of common mode voltage in inverters can be considered as a major issue which leads to motor bearing failures. To eliminate these voltages, proposing some methods seems to be necessary. This paper has a comparative study on estimating modulation methods of eliminating common mode voltage. The main idea of these methods is based on generation of reference vector with nearest ...

a highly efficient cloning vector was constructed for cloning pcr products by inserting an 80 bp dna fragment into pgem-5zf (+) vector. the xcm i digestion of this vector gave rise to a 3’ overhanging deoxythymidine offering the possibility of cloning pcr products with 3' adenosine overhang created by taq dna polymerase. furthermore, two ecor i sites were added to the construct for identificati...

various statistical methods have been proposed in terms of predicting the outcomes of facing special factors. in the classical approaches,  making the probability distribution or known probability density functions is ordinarily necessary to predict the desired outcome. however, most of the times enough information about the probability distribution of studied variables is not available to the ...
