ESA/390 Interpretive-Execution Architecture, Foundation for VM/ESA

The interpretive-execution facility of Enterprise Systems Architecture/390TM (ESA/390TM) provides an instruction for the execution of virtual machines. This instruction, called START INTERPRETIVE EXECUTION (SIE), was initially created for virtualizing either System/370m or 370-XA architectures and was used later for virtualizing ESA/370' and ESA/390 architectures. SIE has evolved to provide cap...

The ESA Ravenscar Benchmark

This article presents ERB, the ESA Ravenscar Benchmark. ERB aims at providing a synthetic benchmark comparing the efficiency of various Ada Ravenscar implementations and the RTEMS C implementation featuring the native threading model. ERB is original compared to existing Ada benchmarks, such as the ACES or the PIWG, not only because it is the first Ada Ravenscar benchmark, but also because it p...

Esa-randomized Controlled Trial

Objective: The aim of this study was to compare clinical outcomes of early versus delayed laparoscopic cholecystectomy (LC) in acute cholecystitis with more than 72 hours of symptoms. Background: LC is the treatment of acute cholecystitis, with consensus recommendation that patients should be operated within 72 hours of evolution. Data however remain weak with no prospective study focusing on p...
