Artificial sensory and motor nervous systems enabled by bioinspired nanowire heterostructure synapse

open access: yesInfoMat, EarlyView.
A p‐i‐n heterostructured junction synaptic transistor was fabricated, composed of poly(3‐hexylthiophene‐2,5‐diyl) nanowire thin‐film/poly(methyl methacrylate)/ZnO nanowires (PZJ STs), which can emulate biological sensory and motor nervous systems.

Beyond the Metrics: Context‐Aware Calibration for Better Drain Flow Modelling

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Robust hydrological and water quality modelling is essential for advancing the understanding and management of engineered agricultural subsurface drainage systems. Achieving credible model output hinges on calibration strategies that are both rigorous and context sensitive. At the field scale, accurately capturing the dynamics of nutrient load

Joint Estimation and Bandwidth Selection in Partially Parametric Models

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT We propose a single‐step approach to estimating a model with both a known nonlinear parametric component and an unknown nonparametric component. We study the large sample behavior of a simultaneous optimization routine that estimates both the parameter vector of the parametric component and the bandwidth vector used to smooth the unknown ...

Revisiting EWMA in High‐Frequency‐Based Portfolio Optimization: A Comparative Assessment

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT This paper compares the statistical and economic performance of state‐of‐the‐art high‐frequency (HF) based multivariate volatility models with a simpler, widely used alternative, the Exponentially Weighted Moving Average (EWMA) filter. Using over two decades of 100 U.S.
