Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

open access: yesInfoMat, EarlyView.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Enhanced peripheral blood mononuclear cell lipid metabolism drives poor immunotherapy response via ferroptotic stress‐induced T cell exhaustion in hepatocellular carcinoma

open access: yesInterdisciplinary Medicine, EarlyView.
Integrated multi‐omics reveals that CD36‐mediated lipid overload in PBMCs drives T cell exhaustion via sub‐lethal ferroptotic stress and AKT suppression. This systemic metabolic signature serves as a robust predictor of immunotherapy response in HCC, suggesting that modulating lipid metabolism can rescue immune fitness.

Improving the Finite Sample Estimation of Average Treatment Effects Using Double/Debiased Machine Learning With Propensity Score Calibration

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT Double/debiased machine learning (DML) uses for estimating an average treatment effect (ATE) a double‐robust score function that relies on the prediction of nuisance functions, such as the propensity score, which is the probability of treatment assignment given covariates.

Decision‐making and risk‐taking as predictors of health risk behaviors in the Millennium Cohort Study

open access: yesJCPP Advances, EarlyView.
Abstract Background Facets of decision‐making and risk‐taking are implicated in adolescent health risk behaviors; however, whether they may lead to adolescent engagement in substance use, gambling, and self‐harm is unknown. Methods We used the Millennium Cohort Study to test whether a task‐based measure of decision‐making and risk‐taking predicts ...
