Transistor‐Level Activation Functions via Two‐Gate Designs: From Analog Sigmoid and Gaussian Control to Real‐Time Hardware Demonstrations

Advanced Materials, EarlyView.
Screen gate‐based transistors are presented, enabling tunable analog sigmoid and Gaussian activations. The SA‐transistor improves MRI classification accuracy, while the GA‐transistor supports precise Gaussian kernel tuning for forecasting. Both functions are implemented in a single device, offering compact, energy‐efficient analog AI processing ...

A Spatio-Temporal Model of House Prices in the US [PDF]

, 2006
In this paper we model the dynamic adjustment of real house prices using data at the level of US States. We consider interactions between housing markets by examining the extent to which real house prices at the State level are driven by fundamentals ...

Unlocking the Full Potential of Zinc Oxide/Cerium Oxide Composite Nanoparticles for Removal of Mixed Pharmaceutical and Dye Pollutants in Water

Advanced Materials Interfaces, EarlyView.
ZnO/CeO2 composite nanoparticles synthesized via a facile hydrothermal method simultaneously degrade ciprofloxacin, tetracycline, methylene blue, and methyl orange in a four‐component mixture under UV irradiation. The Ce3+/Ce4+ redox cycling and oxygen vacancies at the ZnO/CeO2 interface suppress charge recombination and enhance reactive species ...
