Controlled dynamic performance analysis [PDF]

open access: yesProceedings of the 7th international workshop on Software and performance, 2008
We are interested in obtaining detailed performance information on-the-fly from long-running systems without adversely affecting the performance of the systems. We have developed a methodology consisting of a framework, DYPER, and a number of specialized agents called proflets each of which analyzes a different performance aspect.

Time Toxicity in Wilms Tumor: Quantifying the Burden of Healthcare Interaction in the First Year After Diagnosis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Dynamic Performance and the Performance–Performance Rating Relation

open access: yesIndustrial and Organizational Psychology, 2008
In this commentary we discuss the appropriateness and usefulness of taking into account the dynamic nature of performance when considering the relation between job performance and ratings of job performance. Like the vast majority of research in this area, Murphy (this issue) does not critically examine whether or how changes in ratee performance over ...
