Numerical Investigation of the Influence of Interparticle Cohesion During the Shear Behavior of Granular Soil

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Interparticle cohesive forces play a crucial role in governing the shear behavior of many soils; however, quantifying this effect remains challenging due to limited microscopic insights available from laboratory experiments. In this context, the current study aims to investigate the influence of microscale cohesion on the shear response using ...

How Regulatory Costs Impede Financial Technology Gains

European 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 ...
