Heterogeneous Spectral-Spatial Network With 3D Attention and MLP for Hyperspectral Image Classification Using Limited Training Samples

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Methods based on convolutional neural networks (CNNs) have become a vital offshoot for hyperspectral image (HSI) classification. In recent years, the 3-D CNN (3-DCNN) has become dominant due to its excellent capability of extracting features.

Covert Anti-Jamming Communication Based on Gaussian Coded Modulation

open access: yesApplied Sciences, 2021
In several wireless communication systems, robustness against jammers and covertness against eavesdroppers are required simultaneously. In this paper, we propose a novel covert anti-jamming communication system.

“Going out to get in”—Roles of forest conflicts in bottom‐linked environmental governance progressing toward socio‐political innovations

open access: yesEnvironmental Policy and Governance, Volume 32, Issue 6, Page 478-491, December 2022., 2022
Abstract Social innovation literature focuses commonly on roles of cooperation in addressing co‐evolution of civil society initiatives and state‐based governance toward sustainable solutions. However, roles of conflicts in driving social change are scarcely addressed in social innovation literature.

Communicating astronomy with the public: perspectives of an international community of practice [PDF]

open access: yesJCOM_2003_2021_A11, 2021
Communities of practice in science communication can make important contributions to public engagement with science but are under-researched. In this article, we look at the perspectives of a community of practice in astronomy communication regarding (relations with) their public(s).
