Error Algebras [PDF]

open access: yes, 2007
In computations over many-sorted algebras, one typically encounters error cases, caused by attempting to evaluate an operation outside its domain (e.g.

IGF2 knockout reduces but does not abolish osteosarcoma growth in vitro and in vivo

open access: yesFEBS Open Bio, EarlyView.
To test whether endogenous IGF2 promotes osteosarcoma growth, IGF2 was knocked out in Saos2 cells via CRISPR‐Cas9. KO cells showed reduced proliferation in vitro, and knockout xenografts in mice reached only ~25% of wild‐type tumor volume. Insulin‐like growth factor 2 (IGF2) is implicated in osteosarcoma, but direct functional evidence of its role is ...

Rheumatoid arthritis, frailty, and outcomes of surgical hospitalizations: A national population‐based analysis

open access: yesArthritis Care &Research, Accepted Article.
OBJECTIVE Hospitalization, particularly for surgery, represents a period of heightened stress. We evaluated how frailty attenuates the association of rheumatoid arthritis (RA) with negative health outcomes after elective non‐cardiac surgery. METHODS We conducted a cross‐sectional study using the National Inpatient Sample (2018 to 2020), including ...

Analysis of the Influence of Meshing Error and Phase Angle on Load Sharing Characteristic of Compound Planetary Gear Train

open access: yesJixie chuandong, 2016
Taking the compound planetary gear train as research object,a nonlinear translation- torsion coupled dynamics model is established for compound planetary gear train considering the time- varying meshing stiffness,gear backlash and synthetic meshing ...

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

open access: yesAdvanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Statistical analysis of the measurement errors in an installation of water meters. Study on the volume of the water loss in the installation

open access: yesMATEC Web of Conferences, 2017
The paper presents the estimation of the statistical parameters for experimental data collected in an installation consisting of several water meters and also a study on the volume of the water loss in the installation, aiming to emphasize ways in which errors in metering the consumed water are produced.
