Recent experiments indicate that uncorrelated noise models may not be enough to explain the physical behavior of quantum devices, and correlated error must taken into account. Here, authors use a simple model numerically study variational algorithms with is either in time or space. They find can actually improve algorithm performance, due fact there are simply more ways for errors occur system.

Correlations in traffic patterns are an important facet of the workloads faced by real systems, and one that has far-reaching consequences on the performance and optimization of the systems involved. However, all the existing analytical work on understanding the effect of correlations between successive service requirements (job sizes) is limited to First-Come-First-Served scheduling. This leav...

Understanding how correlations can be used for quantum communication protocols is a central goal of quantum information science. While many authors have linked global measures of correlations such as entanglement or discord to the performance of specific protocols, in general the protocols may require only on correlations between specific observables. Here, we introduce a pairwise measure of co...

this research is to examine the relationship between corporate organizational culture and financial performance in iranian ict ministry-affiliated corporations. denison's questionnaire was used to measure organizational culture while four indicators namely return on assets, return on sales, return on owner's equity ratio and operating expenses/operating income ratio were employed in a...

Background: It was hypothesized that under apparently good management practices in dairy farms, some cows may not be metabolically perfect during the breeding period and this may affect their performance. Aims: This study was conducted to assess probable metabolic drawbacks in mid-lactation dairy cows affecting their performance. Methods: Thirt...

Many constraints of organismal design at the cell and organ level, including muscle fiber types, musculoskeletal gearing and control-surface geometry, are believed to cause performance trade-offs at the whole-organism level. Contrary to this expectation, positive correlations between diverse athletic performances are frequently found in vertebrates. Recently, it has been proposed that trade-off...
