A Comparison of Realized Measures of Integrated Volatility: Price Duration‐ vs. Return‐Based Approaches

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT We study the accuracy of a variety of parametric price duration‐based realized variance estimators constructed via various financial duration models and compare their forecasting performance with the performance of various nonparametric return‐based realized variance estimators.

Hydrogen Halide Gas Sensors: Active Materials, Operation Principles, and Emerging Technologies

open access: yesInterdisciplinary Materials, EarlyView.
This review considers hydrogen halide (HX) gas sensors across functional materials and principles: acoustic, chemical, optical and nanophotonic. The strong acidity and reactivity of HX gases are discussed as constraints for stability and selectivity of these devices.

Computational design of two‐dimensional MA2Z4 family field‐effect transistor for future Ångström‐scale CMOS technology nodes

open access: yesInfoMat, EarlyView.
Two‐dimensional MA2Z4 such as MoSi2N4 offer a new path to extend transistor scaling beyond the limits of silicon. Due to their exceptional properties, these 2D semiconductors are promising candidates for future Ångström‐scale CMOS technology. This review outlines the computational design and roadmap bridging materials discovery, device design and ...

Forecasting Natural Gas Prices in Real Time

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT This paper provides a comprehensive analysis of the forecastability of the real price of natural gas in the United States at the monthly frequency considering a universe of models that differ in complexity and economic content. We find that considerable reductions in mean‐squared prediction error relative to a no‐change benchmark can be ...
