A Framework for the Automation of Discrete-Event Simulation Experiments

Simulation is an important resource for researchers in diverse fields. However, many researchers have found flaws in the methodology of published simulation studies and have described the state of the simulation community as being in a crisis of credibility. This work describes the project of the Simulation Automation Framework for Experiments (SAFE), which addresses the issues that undermine credibility by automating the workflow in the execution of simulation studies. Automation reduces the number of opportunities for users to introduce error in the scientific process thereby improvingthe credibility of the final results. Automation also eases the job of simulation users and allows them to focus on the design of models and the analysis of results rather than on the complexities of the workflow.

Biomarkers for Hepatocellular Apoptosis in the Management of Liver Diseases

Apoptosis is a rare event in normal hepatocytes. However, multiple signals can trigger apoptosis in hepatocytes and it plays a role in the pathogenesis of many liver diseases. This review summarizes the mechanisms of hepatocellular apoptosis and the importance of apoptosis in the pathological processes of liver disease. The potential for non-invasive biomarkers of apoptosis to gauge the extent and follow the evolution of clinical disease is emphasized.

Is 7-day event triggered ECG recording equivalent to 7-day Holter ECG recording for atrial fibrillation screening?

Prolonged ECG monitoring is standard for atrial fibrillation (AF) screening. This study investigated whether 7-day event triggered (tECG) ECG recording is equivalent to 7-day continuous Holter (cECG) ECG recording for AF screening.
