Forecasting Renminbi Exchange Rate Volatility Using CARR-MIDAS Model

open access: yesComplexity, 2022
In this study, we propose to employ the conditional autoregressive range-mixed-data sampling (CARR-MIDAS) model to model and forecast the renminbi exchange rate volatility. The CARR-MIDAS model exploits intraday information from the intraday high and low

Meniscus‐Guided Soft‐Lithographic Assembly of Grid‐Type Molecular Martensite Films for Single‐Crystal‐Like Actuation

open access: yesAdvanced Functional Materials, EarlyView.
A meniscus‐guided microtransfer molding strategy enables scalable fabrication of grid‐type molecular martensite films with b‐axis‐correlated preferential texture. Sequential growth across microchannel intersections creates structurally continuous grids and robust thermoelastic actuation (∼11% strain, > 50 cycles, maximum force density: 7.1 × 109 N m−3).
