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 ...

A Sliding Time‐Window Energy Ratio Method for Weak Signal Enhancement of Deep Subgrade Voids in GPR Data

Applied Research, Volume 5, Issue 4, August 2026.
A sliding time‐window energy ratio method is proposed to enhance weak GPR reflections from deep pavement voids. By combining target‐window localization with same‐window normalization, STWER suppresses non‐target interference and improves defect localization, as demonstrated by numerical simulations and field cases verified by excavation and core ...

EVALUATION OF ENGINEERING PROPERTIES OF THERMAL POWER PLANT WASTE FOR SUBGRADE TREATMENT

Journal of Civil Engineering, Science and Technology, 2021
Soft cohesive soils have low strength, high plasticity, and a large expansion ratio making them unsuitable as a road subgrade. This study aims to evaluate the potential of power plant waste (fly ash) from the Barapukuria Thermal Power Plant, Dinajpur, Bangladesh to improve the characteristics of such soft cohesive soil.

Field‐Validated Predictive Model for Strain Modulus of Dispersive Clay Stabilized With a Waste Calcium Composite for Sustainable Subgrade Design

Engineering Reports, Volume 8, Issue 7, July 2026.
A field‐validated predictive model accurately estimates the strain modulus of waste calcium composite‐stabilized dispersive clay. The model provides a reliable, sustainable, and cost‐effective tool for subgrade design, reducing dependence on extensive field testing while improving pavement performance.

Economic Potential of Reusing Construction and Demolition Waste (CDW) as Aggregates in Retrofit Projects

Environmental Quality Management, Volume 36, Issue 1, July 2026.
ABSTRACT This study investigates the technical and economic feasibility of reusing Class A Construction and Demolition Waste (CDW) in urban retrofit projects in Recife, Pernambuco. The research focuses on the production of recycled aggregates for soil stabilization in foundations, a geotechnical application seldom explored in retrofit contexts.
