Self‐Sterilizing Face Mask Employing Enzymatic Power Generation

open access: yesAdvanced Materials Technologies, EarlyView.
Electric face mask with flexible biofuel cell integration for on‐the‐go sterilization is developed utilizing ethanol oxidation via alcohol dehydrogenase, and oxygen reduction via bilirubin oxidase. Modified face mask exhibited bacterial death rates of 40–60% at only 20 µA of electric current, easily generated by the biofuel cell continuously over hours

Smart Theremin Based on Electromagnetic Metasurfaces for Fine Dual‐Hand Perception

open access: yesAdvanced Optical Materials, EarlyView.
The proposed Meta‐Theremin leverages a frequency‐spatial multiplexing metasurface to enable robust dual‐hand perception by shielding environmental noise and confining EM fields to interaction zones. Its physics‐informed neural network decouples hand‐specific echoes, enhancing accuracy.

Relationships of Smiling and Flirtation to Aggression and 2D:4D, a Prenatal Androgen Index

open access: yesEvolutionary Psychology, 2011
Smiling has been reported to be a signal of submission/lower status, or a sign of cooperation. In the present study, use of smiling and flirtation to “make people receptive to my ideas” was conceptualized as mild aggression, since it is mildly ...

Face Gender Influences the Looking Preference for Smiling Expressions in 3.5-Month-Old Human Infants.

open access: yesPLoS ONE, 2015
Young infants are typically thought to prefer looking at smiling expressions. Although some accounts suggest that the preference is automatic and universal, we hypothesized that it is not rigid and may be influenced by other face dimensions, most notably
