In situ coating strategy for flexible all‐perovskite tandem modules: A new path toward high‐efficiency flexible photovoltaics

FlexMat, EarlyView.
A gas‐quenching‐assisted in situ additive strategy (MP‐CW) enables the fabrication of high‐quality wide‐bandgap perovskite films on flexible substrates. By leveraging Cl‐DMSO coordination channels, the approach promotes vertical additive diffusion to remove residual DMSO and passivate buried interfaces. As a result, flexible all‐perovskite tandem solar

A Deep Learning Framework for Forecasting Medium‐Term Covariance in Multiasset Portfolios

Journal of Forecasting, EarlyView.
ABSTRACT Forecasting the covariance matrix of asset returns is central to portfolio construction, risk management, and asset pricing. However, most existing models struggle at medium‐term horizons, several weeks to months, where shifting market regimes and slower dynamics prevail.

Beyond the Bin: The Effect of Waste Reduction on Real Earnings Management

International Journal of Finance &Economics, EarlyView.
ABSTRACT We investigate the effect of waste management strategies on real earnings management. Using a sample of 6515 firm‐year observations from 22 countries spanning the 2011–2022 period, we show that companies that reduce their waste generation are less likely to engage in real earnings management, supporting the ethical theoretical perspective ...

Diversifying Environmental, Social and Governance Portfolios: Evidence From China

International Journal of Finance &Economics, EarlyView.
ABSTRACT This study extends traditional portfolio optimization methods by incorporating Environmental, Social and Governance (ESG) performance measures into diversification strategies, specifically focusing on data from the Chinese stock market. By integrating ESG scores and their constituent components (E, S and G), the study examines portfolio ...

Managing maternity: Moving care, not patients, using artificial intelligence (AI), internet‐of‐things (IOT) and point‐of‐care testing (POCT) devices

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract The integration of artificial intelligence (AI) into healthcare is accelerating and maternity care is at a pivotal moment for the strategic implementation of these technologies. This article explores how AI‐assisted women's health innovations, often termed “FemTech,” may transform pregnancy care by addressing long‐standing disparities ...
