Methylation of elongation factor 1α in mouse 3T3B and 3T3BSV40 cells

AbstractTwo-dimensional gel electrophoretic (NEPHGE) analysis of proteins from mouse 3T3B and 3T3B/SV40 cells labelled with [methyl-3H]methionine in the presence of cycloheximide have revealed that the elongation factor 1α (EF-1α) in these cells is methylated and that the extent of methylation is higher in the SV40 transformed cell type. It is suggested that methylation may account for differences in growth properties for the different cell types

Implementation of a two-qubit controlled-U gate based on unconventional geometric phase with a constant gating time

We propose an alternative scheme to implement a two-qubits Controlled-U gate in the hybrid system atom-$CCA$ (coupled cavities array). Our scheme results in a constant gating time and, with an adjustable qubit-bus coupling (atom-resonator), one can specify a particular transformation $U$ on the target qubit. We believe that this proposal may open promising perspectives for networking quantum information processors and implementing distributed and scalable quantum computation.Comment: 4 pages, 1 figure, APS format, an extended version is in progress with some improvement
