Machine learning‐based predictive models versus traditional risk scores in hemodialysis patients with comorbid urolithiasis

Precision Medical Sciences, EarlyView.
Machine learning‐based predictive models outperform traditional risk scores in hemodialysis patients with comorbid urolithiasis by capturing nonlinear, dialysis‐specific interactions. These approaches enable more accurate prediction of stone recurrence, sepsis, hospitalization, and mortality, supporting personalized risk stratification and precision ...

Amplification of MHD waves in swirling astrophysical flows

, 2003
Recently it was found that helical magnetized flows efficiently amplify Alfv\'en waves (Rogava et al. 2003, A&A, v.399, p.421). This robust and manifold nonmodal effect was found to involve regimes of transient algebraic growth (for purely ejectional ...

Towards the Development of a Conceptual Framework of the Determinants of Pre‐eclampsia: A Hierarchical Systematic Review of Biomarkers

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Background Pre‐eclampsia is a leading cause of maternal and perinatal morbidity and mortality. There are several determinants of individual pregnant women's risk of developing pre‐eclampsia, including biomarkers and ultrasound markers. Objective A conceptual framework to collate and summarise the extensive body of literature on biomarkers ...

Magnetohydrodynamic generators using two-phase liquid-metal flows [PDF]

, 1969
Two-phase flow generator cycle of a magnetohydrodynamic /MHD/ generator uses a working fluid which is compressible and treated as an expanding gas. The two-phase mixture passes from the heat source through the MHD generator, where the expansion process ...

Efficiency comparison between new single‐needle dialysis and conventional double‐needle dialysis and exploration of the optimal prescription parameters for single‐needle hemodialysis

Therapeutic Apheresis and Dialysis, Volume 29, Issue 3, Page 419-427, June 2025.
Abstract Objective To compare the dialysis efficiency parameters between new single‐needle dialysis and conventional double‐needle dialysis and to explore the optimal prescription parameters for single‐needle hemodialysis. Methods This study involved a prospective, cross‐over design. Eight patients were randomly divided into two cohorts, which received
