Dual Guided Loss for Ground-Based Cloud Classification in Weather Station Networks

IEEE Access, 2019
In this paper, we propose a novel loss function named dual-guided loss (DGL) for ground-based cloud classification in weather station networks. The proposed DGL could integrate the knowledge of different convolutional neural networks (CNNs) in the ...

Large‐Area Printed PEDOT:PSS Shielding and Frequency Selective Surface (FSS) on Textiles

Advanced Materials Interfaces, EarlyView.
An all‐polymer e‐textile frequency selective surface (FSS) can present controlled shielding, presenting a competitive alternative to metal‐based inks. The results show how PEDOT: PSS‐based e‐textiles could be applied in RF devices for future wearable applications.

Enhancing Performance and Reliability of Hf1‐xZrxO2 Morphotropic Phase Boundary Films via Nanolaminate Structuring and Microwave Annealing

Advanced Materials Technologies, EarlyView.
Hf–Zr–O‐based morphotropic phase boundary (MPB) thin films often suffer from limited endurance and poor uniformity due to intrinsic phase instability. This work proposes a nanolaminate architecture that spatially separates competing phases, stabilizes phase formation, and suppresses wake‐up‐induced degradation.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
