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

InfoMat, 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 ...

High‐Frequency Instruments With Time‐Varying Reliability: Understanding Identification in Macroeconomics

Journal of Applied Econometrics, EarlyView.
ABSTRACT The effects of monetary policy shocks are regularly estimated using high‐frequency surprises in asset prices around central bank meetings as an instrument. These studies, insofar as they explicitly model the relationship between instrument and structural shock, assume a constant relationship between the instrument and the monetary policy shock.

Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations

Journal of Applied Toxicology, EarlyView.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of

Melanoma Cells Exposed to Clomiphene Citrate Respond With Cell Cycle Arrest and Reduced Invasiveness

Journal of Applied Toxicology, EarlyView.
ABSTRACT Epidemiological studies have suggested that clomiphene citrate (CC) exposure may increase the risk of malignant melanoma, but mechanisms are unknown. We investigated the effects of CC on melanoma cell line A375. Cells were treated with CC at 2, 20, 200, and 2000 ng/mL, followed by assessment of cell viability and metabolism, cell cycle ...
