Analog Control of Reconfigurable GHz Resonances from Chiral Spin Texture Ensembles

Advanced Materials, EarlyView.
Tunable microwave components ‐ essential for wireless technology ‐ typically require costly, customized nanofabrication. We show that ambient spin texture ensembles (e.g., magnetic skyrmions) in chiral multilayer films can enable reconfigurable microwave resonators.

Sparse-grid finite-volume multigrid for 3D-problems [PDF]

Advances in Computational Mathematics, 1995
This paper introduces a multigrid method based on Haar wavelets, and the method is applied to second-order, elliptic partial differential equations. It is shown that the question of which collection of Haar wavelets to use as a basis has significant influence on the computational efficiency.

Chemomechanical Origin of Morphological Disparity in Lithium Metal Electrodeposition

Advanced Materials, EarlyView.
Selective dissociation of either solvent or salt on copper current collector induced different solid electrolyte interphase (SEI) layers. The solvent derived organic SEI favors formation of Li whisker, while salt derived SEI favors formation of Li particle, revealing the root cause of Li morphology disparity within the same cell.

SCNet: Subdivision Coding Network for Object Detection Based on 3D Point Cloud

IEEE Access, 2019
High-precision real-time 3D object detection based on the LiDAR point cloud is an important task for autonomous driving. Most existing methods utilize grid-based convolutional networks to handle sparse and cluttered point clouds. However, the performance

Downscaling top-down CO2 emissions and sinks in China empowered by hybrid training

npj Climate and Atmospheric Science
Atmospheric CO2-based top-down approaches enable objective evaluation of climate mitigation efforts but face dual constraints: sparse monitoring limits spatial resolution, while emission heterogeneity hampers downscaling. To enhance downscaling accuracy,
