Natural Gradient Boosting for Probabilistic Prediction of Soaked CBR Values Using an Explainable Artificial Intelligence Approach

open access: yesBuildings
The California bearing ratio (CBR) value of subgrade is the most used parameter for dimensioning flexible and rigid pavements. The test for determining the CBR value is typically conducted under soaked conditions and is costly, labour-intensive, and time-

How Regulatory Costs Impede Financial Technology Gains

open access: yesEuropean Financial Management, EarlyView.
ABSTRACT While financial technology innovation lowers intermediation costs, regulatory frictions may prevent these gains from reaching long‐term investors and borrowers. Using variation in retail investor participation driven by state securities registration lapses in peer‐to‐peer lending, we demonstrate that regulatory frictions are associated with ...

Severity of perineal tears and deviations in perineal body anatomy: A three‐dimensional ultrasound study

open access: yesActa Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 7, Page 1295-1302, July 2026.
Sonographic deviations in the muscles fusing into the perineal body were increasingly common with greater perineal tear severity 1 year after delivery in primiparous women. Abstract Introduction Perineal tears are classified into four degrees based on severity.
