Abstract The Large Magellanic Cloud supernova remnant J0454-6713 abutting the H ii region N9 has been observed with XMM-Newton. Two groups of lines from Fe xvii account for half emission and xviii , O vii viii are also clearly detected XMM RGS. Isothermal equilibrium fits EPIC spectra reproduce basic spectral form show little variation throughout but insensitive to high-temperature ions. These ...

We present two algorithms in the quantum CONGEST-CLIQUE model of distributed computation that succeed with high probability: one for producing an approximately optimal Steiner tree, and exact directed minimum spanning each which uses O˜(n1/4) rounds communication O˜(n9/4) messages, achieving a lower asymptotic round message complexity than any known classical model. At level, we achieve these r...

peptide synthesis. Enzymatic peptide synthesis is more advantageous than chemical synthesis since the enzymatic method is stereoselective and is secure from racemization. There are, however, several problems to be solved with this method. Secondary hydrolysis of the resulting peptide may arise from the inherent nature of the protease. Moreover, the method is limited to the use of amino acid der...
