Impedance Modeling and Analysis of PV Inverters Considering Fractional‐Order Characteristics of Elements

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
This manuscript finds that the previous impedance modeling and stability analysis methods for photovoltaic inverters have not yet considered the fractional‐order characteristics of the elements; in order to make up for the blank in this research field, this paper carried out relevant work.

Blasting effects of cross‐fault deep‐buried excavation on adjacent existing tunnel stability

open access: yesDeep Underground Science and Engineering, EarlyView.
Based on the theoretical analysis of cylindrical wave propagation in a deep rock mass in the fault with a filling layer, the calculation method of peak particle velocity caused by wave propagation in the existing tunnel is established. The viscoelastic characteristics of a rock mass are examined in the analysis.

A contemporary simple risk score for prediction of severe acute kidney injury after heart transplantation

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1166-1175, April 2025.
A contemporary simple risk score for prediction of severe AKI after HT. Abstract Background The aim of this study was to develop a simple risk score to estimate severe acute kidney injury (AKI) risk based on a large contemporary heart transplantation (HT) cohort.

Uncertainty in inventories for life cycle assessment: State‐of‐the‐art, challenges, and new technologies

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Uncertainty is a critical factor that can hinder the quality and potential applications of life cycle assessment (LCA) results. A prominent source of uncertainty stems from the life cycle inventory (LCI) data. Various methodologies exist to estimate the uncertainty associated with LCI data, primarily based on the widely used structured ...
