Estimating Treatment Effects With Limited Exogeneity: A Machine Learning Approach to Selection Bias

International Studies of Economics, Volume 21, Issue 1, Page 2-8, March 2026.
ABSTRACT This paper presents a novel method for estimating treatment effects in cases where prior knowledge of the exogeneity of the treatment variable is limited. We employ a machine learning technique, double selection via Lasso, to identify a robust set of control variables without requiring prior assumptions about their specific identities or ...

A Stacking Ensemble Model for Specific Yield Prediction: Framework Development and Application to Groundwater Storage Change Estimation in the North China Plain

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Specific yield (SY) is a key parameter in estimating groundwater storage change. Accurately predicting SY in unconfined aquifers remains challenging, as SY varies with groundwater‐level fluctuations and unsaturated‐zone moisture fluxes. This challenge is particularly evident in the North China Plain (NCP), which has experienced substantial ...

More Than Just a Game: How Intrinsic Motivation and Artificial Intelligence‐Enhanced Trading Shape Consumer Well‐Being in Virtual Markets

Psychology &Marketing, Volume 43, Issue 2, Page 401-430, February 2026.
ABSTRACT This study aims to enhance our understanding of the factors that predict well‐being in video gaming, a rapidly growing form of entertainment and social engagement. Using self‐determination theory (SDT), the research explores the behaviors of gamer consumers. Data were collected through an online questionnaire.

Evaluating the Complementary Relationship Hypothesis in a Monsoon Climate: Challenges and Future Directions

JAWRA Journal of the American Water Resources Association, Volume 61, Issue 6, December 2025.
ABSTRACT The complementary relationship of evapotranspiration (CRE) hypothesis has been widely used to estimate actual evapotranspiration (AET) indirectly under various climatic conditions. However, its applicability in monsoon‐dominated regions remains underexplored. This study investigates the dynamics of potential evapotranspiration (PET) and AET in

Theory of dynamical superradiance in organic materials

Nanophotonics, Volume 14, Issue 27, Page 5323-5336, December 2025.
Abstract We develop the theory of dynamical superradiance – the collective exchange of energy between an ensemble of initially excited emitters and a single‐mode cavity – for organic materials where electronic states are coupled to vibrational modes.

Improving Dryland Depth to Water Table Estimate Using an Integrated Model With Three Submodels

Water Resources Research, Volume 61, Issue 10, October 2025.
Abstract Investigating dryland phreatic water assets requires an in‐deep understanding of depth to water table (DWT). However, current DWT methods suffer from limited accuracy and demand refinement. Therefor, this study suggests one novel integrated model cascaded by twin, assimilation, and DWT submodels.

Advancing Evapotranspiration Modeling With Optimized Soil and Canopy Resistance Combinations

Water Resources Research, Volume 61, Issue 6, June 2025.
Abstract Dual‐source remotely sensed evapotranspiration (ET) models require accurate separation of soil evaporation (Es), plant transpiration (Ec), and precipitation interception (Ei) based on soil and canopy resistances. Despite the availability of several ET products and algorithms, comprehensive evaluations of resistance configurations remain scarce.

Seasonal Delay of Tropical Rainfall Enhanced by the Interhemispheric Contrast of SST Warming

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract The seasonal delay of tropical rainfall is a robust feature under global warming. This study finds that the seasonal delay of tropical rainfall is much more pronounced under spatially patterned sea surface temperature (SST) warming compared to uniform SST warming.
