A fidelity measure for quantum channels

We propose a fidelity measure for quantum channels in a straightforward analogy to the corresponding mixed-state fidelity of Jozsa. We describe properties of this fidelity measure and discuss some applications of it to quantum information science.Comment: 14 pages; elsart.st

IECLB: decadência por cima — renovação por baixo

Como é fácil perceber os artigos deste número partem, em sua expressiva maioria, de experiências vividas. Este é também o caso na contribuição de Werner Fuchs, que tem por base experiências feitas junto ao trabalho nas comunidades de Santa Helena e Curitiba (PR). Seu texto "provoca" comunidades, pastores/as e a instituição eclesiástica, a fim de encararem os conflitos existentes. O artigo trata da decadência e renovação dentro da Igreja. Procura ver estes processos tanto em relação à instituição ("em cima") como na reação que desencadeiam nas bases ("em baixo"). Sobretudo avalia o papel desempenhado pela "estrutura" da igreja e o conflito de classes existente dentro da IECLB. Werner não tem dúvidas: a renovação vem de baixo para cima

Genome-Based Analyses of Fitness Effects and Compensatory Changes Associated with Acquisition of blaCMY-, blaCTX-M-, and blaOXA-48/VIM-1-Containing Plasmids in Escherichia coli

Background: Resistance plasmids are under selective conditions beneficial for the bacterial host, but in the absence of selective pressure, this carriage may cause fitness costs. Compensation of this fitness burden is important to obtain competitive ability under antibiotic-free conditions. In this study, we investigated fitness effects after a conjugative transfer of plasmids containing various beta-lactamase genes transferred into Escherichia coli. (2) Methods: Fourteen beta-lactamase-encoding plasmids were transferred from clinical donor strains to E. coli J53. Growth rates were compared for all transconjugants and the recipient. Selected transconjugants were challenged in long-term growth experiments. Growth rates were assessed at different time points during growth for 500 generations. Whole-genome sequencing (WGS) of initial and evolved transconjugants was determined. Results: Most plasmid acquisitions resulted in growth differences, ranging from −4.5% to 7.2%. Transfer of a single blaCMY-16-carrying plasmid resulted in a growth burden and a growth benefit in independent mating. Long-term growth led to a compensation of fitness burdens and benefits. Analyzing WGS revealed genomic changes caused by Single Nucleotide Polymorphisms (SNPs) and insertion sequences over time. Conclusions: Fitness effects associated with plasmid acquisitions were variable. Potential compensatory mutations identified in transconjugants’ genomes after 500 generations give interesting insights into aspects of plasmid–host adaptationsPeer Reviewe
