High Voltage, EarlyView.ABSTRACT To address the limitations of traditional transformer health index (HI), such as high dependence on data integrity and inability to assist in diagnosing latent faults, this study proposes an HI prediction method based on dynamic Bayesian network (DBN).

High Voltage, EarlyView.ABSTRACT With increasing demands for fire safety and environmental friendliness, retrofilling transformers with alternative insulating liquids has become a growing trend. However, retrofilling power transformers remains uncertain, as more residual mineral oil compromises K‐class flame retardancy, and its impact on environmental performance has yet to ...

High Voltage, EarlyView.ABSTRACT A reduced‐order model (ROM) for the temperature field based on time‐space proper orthogonal decomposition (POD) is presented to improve the computational efficiency of transient temperature rise in oil‐immersed power transformers with a complete oil natural convection cooling loop.

Trial‐Based Hemolysis Modeling to Investigate Operating Modes of Continuous‐Flow LVADs
Artificial Organs, EarlyView.This work presents a methodology for determining online‐capable hemolysis models for continuous‐flow LVADs, derived from in vitro trials. The models are based on fitting a modified power law and applying the Lagrangian approach. They assist clinicians in selecting treatment strategies that minimize hemolysis, as demonstrated with the Sputnik1 LVAD ...

Inflation expectations and time variations in the oil price pass‐through
Economic Inquiry, EarlyView.Abstract Previous literature suggests that the pass‐through of oil price shocks to inflation rates became weaker since the 1970s. I use a time‐varying parameter VAR to show that this trend has recently been reversed with headline and core inflation rates responding more sensitive to oil price shocks. Based on a counterfactual analysis, I offer evidence

European Journal of Haematology, EarlyView.ABSTRACT Background Central venous catheters (CVCs) are essential in pediatric hematology‐oncology, for the administration of chemotherapy and supportive therapy. Thrombocytopenia increases the risk of bleeding and current guidelines recommend prophylactic platelet transfusions below 40–50 × 109/L, though evidence is limited and transfusions entail ...

Headache: The Journal of Head and Face Pain, EarlyView.Abstract Objectives/Background Persistent headache (PH) after an aneurysmal subarachnoid hemorrhage (aSAH) and the influence of migraine history (MH) on its evolution and prognosis is poorly understood. Our study aims are to (1) determine the prevalence, characteristics, and prognostic factors of PH after aSAH; and (2) study the impact of personal MH ...

Immobilized CuCl2/TiO2 photocatalysts for the selective oxidation of benzyl alcohol to benzaldehyde
Photochemistry and Photobiology, EarlyView.The photocatalytic aerobic oxidation of benzyl alcohol to benzaldehyde was investigated using free and alginate‐immobilized CuCl2 and/or TiO2 (P25) catalysts under UV irradiation. Immobilization enabled catalyst recovery and maintained high benzaldehyde selectivity but led to reduced activity due to internal oxygen diffusion limitations, which were ...
