Volatility made observable at last [PDF]
The Cartier-Perrin theorem, which was published in 1995 and is expressed in the language of nonstandard analysis, permits, for the first time perhaps, a clear-cut mathematical definition of the volatility of a financial asset.

Variable‐Range Hopping Conduction in Amorphous, Non‐Stoichiometric Gallium Oxide
Advanced Electronic Materials, EarlyView.The combination of experimental evidence, ab‐initio DOS calculations and quantitative modeling by kinetic Monte Carlo simulations reveals: Variable‐range hopping (VRH) is the dominant electron conduction mechanism in a‐GaOx (x = 0.8 to 1.0), even at room temperature, which leads to a new, fundamental understanding of a‐GaOx‐based electronic devices ...

Advanced Electronic Materials, EarlyView.A highly robust double memristor based on a molybdenum oxide‐molybdenum sulfide/perovskite heterojunction is demonstrated. Good resistive switching behavior with an endurance of 100 cycles, high retention of 2·× 104 s, and ON/OFF ratio of ≈102 is reported to emulate successfully the biosynapse's behavior.

A Comprehensive Guide to Fully Inkjet‐Printed IGZO Transistors
Advanced Electronic Materials, EarlyView.Inkjet printing of indium‐gallium‐zinc‐oxide (IGZO), a promising material for liquid‐crystal display thin‐film transistors (TFTs), has been common practice for many years. Nevertheless, fully inkjet‐printed IGZO transistors, including dielectric and electrode components, are a novelty. This review thoroughly reviews ink formulations, the intricacies of
