The thermo-driven photocatalytic CO2 hydrogenation was studied for NiOx/Nb2O5 from the point of CO2 and H2 adsorption behavior. Photothermal synergistic and Ni modification dramatically changed the electron transfer behavior of CO2 adsorption (CO2 (ads)) and H2 (ads) via regulating Fermi level...

Three most prominent theoretical state variables, inflation, scaled market prices, and market variance, are identified as best market return predictor variables via best subset variable selection. They work better together than individually, consistent with multifactor equity premia stressed by...

Bankruptcy and delisting due to other failures are two closely related yet sharply different distress events. Using a state-of-the-art adaptive Lasso variable selection method, we identify two different models for bankruptcy risk and other-failure risk. Both selected models gain better...

The functional coefficient regression models assume that the regression coefficients vary with some "threshold" variable, providing appreciable flexibility in capturing the underlying dynamics in data and avoiding the so-called "curse of dimensionality" in multivariate nonparametric estimation....

Nonparametric quantile regression with multivariate covariates is a difficult estimation problem due to the "curse of dimensionality". To reduce the dimensionality while still retaining the flexibility of a nonparametric model, we propose modeling the conditional quantile by a single-index...

We consider the classic cake-division problem when the cake is a heterogeneous good represented by an interval in the real line. We provide a mechanism to implement, in an anonymous way, an envy-free and efficient allocation when agents have private information on their preferences. The...
