Low‐temperature soft electrochemical actuator based on hierarchically structured polypyrrole membranes for subzero operation

open access: yesFlexMat, EarlyView.
A soft electrochemical actuator using a hierarchically structured polypyrrole membrane with coral‐like hollow vesicles achieves stable performance at −24°C. The unique architecture ensures continuous conductivity and rapid ion diffusion, resulting in large strain, low energy consumption, and high coulombic efficiency under subzero conditions. This work

Coherent Forecasting of Realized Volatility

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT The QLIKE loss function is the stylized favorite of the literature on volatility forecasting when it comes to out‐of‐sample evaluation and the state of the art model for realized volatility (RV) forecasting is the HAR model, which minimizes the squared error loss for in‐sample estimation of the parameters.

Mesoscale Circulation and Coral Community Disturbance at Isolated Reefs

open access: yesGlobal Change Biology Communications, EarlyView.
The Loop Current is a seasonally and interannually dynamic mesoscale oceanographic feature in the Gulf of Mexico that strongly influences connectivity and environmental conditions across the region. We investigated the influence of Loop Current variability on coral reef disturbances at isolated reefs in the northwest Gulf, including coral disease ...
