Effective Benchmarks for Optical Turbulence Modeling
Artificial Intelligence for the Earth SystemsAbstract Optical turbulence poses a significant challenge for communication, directed energy, and imaging systems, particularly in the atmospheric boundary layer. Effective modeling of optical turbulence is crucial for the development and deployment of these systems, yet the lack of standardized evaluation tools and benchmark datasets

Dynamic Spillovers Between FinTech, Blockchain, and Green Finance: A Quantile Connectedness Approach
Business Strategy and the Environment, EarlyView.ABSTRACT This paper explores how financial innovation and environmental sustainability intersect by analyzing spillovers between FinTech, blockchain energy use, and green finance. Using a Quantile Vector Autoregression (QVAR) framework, we examine weekly data from 2018 to 2024 across 11 digital, environmental, and macro‐financial indices.

Fueling Tomorrow: Scenario Planning for the Future of Gas Stations
Business Strategy and the Environment, EarlyView.ABSTRACT Transport electrification is reshaping the service infrastructures that mediate everyday mobility, yet most electrification scenario studies remain macrolevel and offer limited insight into how incumbent forecourt (gas‐station) networks can adapt under deep uncertainty.

Too Complex to Control? How Firms Navigate Scope 3 Governance Under Institutional Uncertainty
Business Strategy and the Environment, EarlyView.ABSTRACT As Scope 3 emissions make up the largest share of many firms' carbon footprints, firms face growing pressure to manage emissions beyond their direct control. Ongoing revisions of the CSRD, the GHG Protocol, and the SBTi Net‐Zero Standard further increase regulatory and methodological uncertainty.

Atmospheric Turbulence Phase Reconstruction via Deep Learning Wavefront Sensing
SensorsThe fast and accurate reconstruction of the turbulence phase is crucial for compensating atmospheric disturbances in free-space coherent optical communication. Traditional methods suffer from slow convergence and inadequate phase reconstruction accuracy.

Business Strategy and the Environment, EarlyView.ABSTRACT What propels a CFO in an emerging economy to champion ESG investments when formal regulations are weak? Moving beyond structural explanations, we provide a behavioural account arguing that a manager's internal ethical compass—moral intelligence (MI)—is a key driver.
