Defining representative workloads, involving workload intensity and service calls within user sessions, is a core requirement for meaningful performance testing. This paper presents the approach for obtaining representative workload models from production systems that has been developed in the DynaMod project for model-driven software modernization.
The specification of workloads is required in order to evaluate performance characteristics of application systems using load testing and model-based performance prediction. Defining workload specifications that represent the real workload as accurately as possible is one of the biggest challenges in both areas. To overcome this challenge, this paper… (More)
In eukaryotes, DNA methylation is an important epigenetic modification that is generally involved in gene regulation. Methyltransferases (MTases) of the DNMT2 family have been shown to have a dual substrate specificity acting on DNA as well as on three specific tRNAs (tRNA(Asp), tRNA(Val), tRNA(Gly)). Entamoeba histolytica is a major human pathogen, and… (More)
The major virulence factor of the neuroinvasive pathogen Escherichia coli K1 is the K1 capsule composed of α2,8-linked polysialic acid (polySia). K1 strains harboring the CUS-3 prophage modify their capsular polysaccharide by phase-variable O-acetylation, a step that is associated with increased virulence. Here we present the crystal structure of the… (More)
